Functional Dependence of IM and HV Angle in Hallux Valgus Deformity before and after Operative

Hallux valgus is a relatively common and multifaceted complex deformity of the front part of the foot. It is the result of multiple effects of innate (endogenous) and exogenous etiological factors with different degrees of influence. The degree of hallux valgus deformity is usually assessed by radiological values of hallux valgus (HV) and intermetatarsal (IM) angles. The aim of the paper is to justify the definition of hallux valgus deformity as a function of one angle, (HVA or IMA), and then to determine the functional connection and the most suitable function equalizing the values of the angles IMA and HVA. As hallux valgus is a double angulation deformity, the analytically determined connection between the HVA and IMA angles reduces the study of the deformity to the study of function with one argument, and makes the analysis of deformity changes before and after operative treatment simpler. For the determined connections between the angles, the values of linear proportionality coefficients and regression coefficients of corresponding linear functions of analytical equalization of the value of the IM angle and the degree of deformity for a given value of the HV angle were experimentally determined. The obtained results were checked on a sample of 396 operatively treated hallux valgus deformities. The presented analytical approach and the obtained functional links of IMA and HVA enable quantitative observation of the change in the degree of deformity based on the radiologically determined value of these angles, and the established nonlinear function will be useful for evaluating the expected value of the IM angle and the degree of deformity based only on the measured value of the HV angle. .

The application of the strip-shaped cymba conchae orthosis in the nonsurgical correction of complex auricular deformity

Objective: This study aims to evaluate the efficacy and safety of using a strip-shaped cymba conchae orthosis for the nonsurgical correction of complex auricular deformities. Methods: Clinical data were collected from 2020 to 2021 for 6 patients who underwent correction using a stripshaped cymba conchae orthosis. The indications, corrective effects, and complications associated with use of the orthosis were analyzed. Results: There were four indications for treatment: cryptotia with helix adhesion;cryptotia with grade I microtia;cryptotia with excessive helix thickness;and auricular deformity beyond the treatment time window(≥6 months). Excellent corrective effects were observed in all 6 patients. Complications occurred in one patient, who recovered after symptomatic treatment. Conclusion: The use of a strip-shaped cymba conchae orthosis alone or combined with a U-shaped helix orthosis presents a feasible approach for correcting complex auricular deformities or deformities beyond the treatment time window in pediatric patients.

Classification of Hallux Valgus Using Conjugated Deformity

Hallux valgus is a complex deformity of the forefoot. It is the result of multiple effects of endogenous and exogenous etiological factors with different degrees of influence. The degree of hallux valgus deformity was assessed by radiological values of hallux valgus (HVA) and intermetatarsal (IMA) angle. Thus, each hallux valgus deformity corresponds to a pair (HVA, IMA) of hallux valgus angle (HVA) and intermetatarsal angle (IMA) values in the plane of the deformity. The intensity of the point position vector S (HVA, IMA) in the deformation plane determined by the relation represents the absolute (conjugate) value of the power deformities. The goal of the article is to explain the advantage of the definition of the degree of hallux valgus deformity using its absolute (conjugate) value, and then to show that the degree of deformity defined in this way enables a better classification of deformities for all values of the HVA and IMA angles. Furthermore, in this article, applying the definition of conjugate deformity, analytical expressions were constructed for the assessment of the average value of deformity correction after operative treatment, as well as the error assessment of deformity correction after operative treatment. All obtained results were checked on a sample of 396 operatively treated feet.

"Meridian-sinew Acupuncture Method"Improves Deformity Joint Dysfunction in Rheumatoid Arthritis

Joint deformity and dysfunction are common and serious complications in the late stage of rheumatoid arthritis,which seriously affect the quality of life of patients.Traditional Chinese medicine(TCM)believes that joint deformity and dysfunction in some patients with rheumatoid arthritis are closely related to the apraxia of meridians and tendons due to enduring illness.Based on the theory of meridians and tendons circulation,using the local and nearby therapeutic effect of acupoints as the treatment method in clinical practice,we conducted penetration needling of Houxi,Baxie,Wailaogong as well as Ashi points of interphalangeal joints of both hands through bilateral Sanjian,and used the uniform reinforcing-reducing method to soothe tendons and meridians,thus effectively improving the dysfunction of deformed joints.

Coronal plane deformity around the knee in the skeletally immature population:A review of principles of evaluation and treatment

Coronal plane deformity around the knee,also known as genu varum or genu valgum,is a common finding in clinical practice for pediatricians and orthopedists.These deformities can be physiological or pathological.If untreated,pathological deformities can lead to abnormal joint loading and a consequent risk of premature osteoarthritis.The aim of this review is to provide a framework for the diagnosis and management of genu varum and genu valgum in skeletally immature patients.

Management of tear trough deformity with and without tear trough-orbicularis retaining ligament complex release in transconjunctival blepharoplasty: a comparative study

AIM: To evaluate the effect of releasing the orbicularis retaining ligament(ORL) complex of the tear trough combined with the transconjunctival blepharoplasty in the surgical management of tear trough deformity compared with the effect of blepharoplasty alone. METHODS: A prospective, randomized(by closed envelope technique), controlled surgical trial which included 50 patients(100 eyes) with bilateral visible tear trough deformity and lower eyelid fat bulging, was divided into two groups where 25 patients(50 eyes) had tear trough-ORL release with blepharoplasty and 25 patients(50 eyes) didn't. Qualitative and quantitative assessments of tear trough deformity were done at 6 mo postoperatively, achieving grade 0 or 1 of Barton's classification was considered a success. Standardized photographic documentation of each patient was done pre and postoperatively, also assessment of the patients' satisfaction postoperatively was done and ranked as excellent, very good, good or fair. RESULTS: There was statistically significant difference between the two groups in the overall aesthetic results postoperatively regarding the qualitative and quantitative analysis of the tear trough deformity, where patients who had tear trough-ORL complex release had more successful outcomes than those of the second group. CONCLUSION: ORL release should be done in patients with tear trough deformity in order to release the tethering effect of this ligament which causes the prominence of the naso jugal groove.

Novel association between sperm deformity index and oxidative stress-induced DNA damage in infertile male patients

Aim:To investigate the impact of abnormal sperm morphology using the sperm deformity index (SDI) on reactive oxygen species (ROS) production and its correlation with sperm DNA damage.Methods:Semen samples were collected from men undergoing infertility screening (n=7) and healthy donors (n=6).Mature spermatozoa were isolated and incubated with 5 mmol/L β-nicotinamide adenine dinucleotide phosphate (NADPH) for up to 24 h to induce ROS.Sperm morphology was evaluated using strict Tygerberg's criteria and the SDI.ROS levels and DNA damage were assessed using chemiluminescence and terminal deoxynucleotidyl transferase-mediated fluorescein- dUTP nick end labeling (TUNEL) assays,respectively.Results:SDI values (median [interquartiles]) were higher in patients than donors (2 [1.8,2.1] vs.1.53 [1.52,1.58],P=0.008).Aliquots treated with NADPH showed higher ROS levels (1.22 [0.30,1.87] vs.0.39 [0.10,0.57],P=0.03) and higher incidence of DNA damage than those not treated (10 [4.69,24.85] vs.3.85 [2.58,5.10],P=0.008).Higher DNA damage was also seen following 24 h of incubation in patients compared to donors.SDI correlated with the percentage increase in sperm DNA damage following incubation for 24 h in samples treated with NADPH (r=0.7,P=0.008) and controls (r=0.58,P=0.04). Conclusion:SDI may be a useful tool in identifying potential infertile males with abnormal prevalence of oxidative stress (OS)-induced DNA damage.NADPH plays a role in ROS-mediated sperm DNA damage,which appears to be more evident in infertile patients with semen samples containing a high incidence of morphologically abnormal spermatozoa.

Cochlear implantation outcomes in children with common cavity deformity;a retrospective study

Objective: A common cavity deformity(CCD) is a deformed inner ear in which the cochlea and vestibule are confluent forming a common rudimentary cystic cavity that results in profound hearing loss. There are few studies paying attention to common cavity. Our group is engrossed in observing the improvement of auditory and verbal abilities in children who have received cochlear implantation(CI), and comparing these targets between children with common cavity and normal inner ear structure.Material and methods: A retrospective study was conducted in 12 patients with profound hearing loss that were divided into a common cavity group and a control group, six in each group matched in sex, age and time of implantation, based on inner ear structure. Categories of Auditory Performance(CAP) and speech intelligibility rating(SIR) scores and aided hearing thresholds were collected and compared between the two groups. All patients wore CI for more than 1 year at the Cochlear Center of Anhui Medical University from 2011 to 2015.Results: Postoperative CAP and SIR scores were higher than before operation in both groups(p < 0.05), although the scores were lower in the CCD group than in the control group(p < 0.05). The aided threshold was also lower in the control group than in the CCD group(p < 0.05).Conclusion: Even though audiological improvement in children with CCD was not as good as in those without CCD, CI provides benefits in auditory perception and communication skills in these children.

Computer-aided Design and Custom-made Guide in Corrective Osteotomy for Complex Femoral Deformity

Summary： Preoperative planning of corrective osteotomy with traditional radiography has limitations in regards to determining the ideal osteotomy location and orientation in three-dimensional femoral de- formities. Though a successful operation can be planned preoperatively, intraoperative contingencies might adhere to the procedural plan in the performance of operation. To efficiently perform a planned procedure, proposed is a design to implement three-dimensional reconstruction photography, based on computer-tomography （CT） scan. A custom-made guide was designed to navigate the osteotomy as planned, and additionally, a personalized intramedullary nail was used for fixation after osteotomy. Three-dimensional （3D） photography of deformed femur was established based on the CT dataset and transferred into 3D photography processing software for further planning. Osteotomy planes were de- signed and adjusted at deformity sites to correct the 3D deformities. The methodology of a custom-made osteotomy guide was introduced in femoral corrective osteotomy, for the first time, to navigate the op- eration as planned. After the virtual osteotomy and reduction of bone segments, the parameters of a custom-made intramedullary nail were measured for manufacturing. Findings Virtual operation in computer shows complete correction of the 3D deformity. The osteotomy guide, obtained by rapid-prototyping techniques, navigates mimicking surgery on rapid-prototyping model of the involved femur as planned. Internal fixation was achieved using the custom-made intramedullary nail. Interpreta- tion three-dimensional visualization introduces an advantage in preoperative planning for corrective os- teotomy of 3D femoral deformity, and the custom-made osteotomy guide is crucial to realize such a de- liberate plan during the actual procedures. The internal fixator, such as an intramedullary nail, can be modified or personalized for fixation in unique cases.

Predictors of spine deformity progression in adolescent idiopathic scoliosis: A systematic review with meta-analysis

AIM: To evaluate published data on the predictors of progressive adolescent idiopathic scoliosis(AIS) in order to evaluate their efficacy and level of evidence. METHODS: Selection criteria:(1) study design: randomized controlled clinical trials, prospective cohort studies and case series, retrospective comparative and none comparative studies;(2) participants: adolescents with AIS aged from 10 to 20 years; and(3) treatment: observation, bracing, and other. Search method: Ovid MEDLINE, Embase, the Cochrane Library, Pub Medand patent data bases. All years through August 2014 were included. Data were collected that showed an association between the studied characteristics and the progression of AIS or the severity of the spine deformity. Odds ratio(OR), sensitivity, specificity, positive and negative predictive values were also collected. A metaanalysis was performed to evaluate the pooled OR and predictive values, if more than 1 study presented a result. The GRADE approach was applied to evaluate the level of evidence.RESULTS: The review included 25 studies. All studies showed statistically significant or borderline association between severity or progression of AIS with the following characteristics:(1) An increase of the Cobb angle or axial rotation during brace treatment;(2) decrease of the rib-vertebral angle at the apical level of the convex side during brace treatment;(3) initial Cobb angle severity(> 25o);(4) osteopenia;(5) patient age < 13 years at diagnosis;(6) premenarche status;(7) skeletal immaturity;(8) thoracic deformity;(9) brain stem vestibular dysfunction; and(10) multiple indices combining radiographic, demographic, and physiologic characteristics. Single nucleotide polymorphisms of the following genes:(1) calmodulin 1;(2) estrogen receptor 1;(3) tryptophan hydroxylase 1;(3) insulin-like growth factor 1;(5) neurotrophin 3;(6) interleukin-17 receptor C;(7) melatonin receptor 1B, and(8) Scoli Score test. Other predictors included:(1) impairment of melatonin signaling in osteoblasts and peripheral blood mononuclear cells(PBMC);(2) G-protein signaling dysfunction in PBMC; and(3) the level of platelet calmodulin. However, predictive values of all these findings were limited, and the levels of evidence were low. The pooled result of brace treatment outcomes demonstrated that around 27% of patents with AIS experienced exacerbation of the spine deformity during or after brace treatment, and 15% required surgical correction. However, the level of evidence is also low due to the limitations of the included studies.CONCLUSION: This review did not reveal any methods for the prediction of progression in AIS that could be recommended for clinical use as diagnostic criteria.

Mid-term Outcomes of Primary Constrained Condylar Knee Arthroplasty for Severe Knee Deformity

This study aimed to examine the clinical and radiographic outcomes of primary total knee arthroplasy（TKA） with use of Nex Gen#174; Legacy#174; Constrained Condylar Knee（CCK） prosthesis for severe knee deformity. Clinical data of 46 patients（48 knees in total, aged 61 years on average） with severe knee deformity who underwent TKA with Nex Gen#174; Legacy#174; CCK prosthesis between December 2007 and February 2012 were retrospectively analyzed. There were 34 knees with severe valgus with incompetent medial collateral ligament, 11 knees with severe flexion contracture with inability to achieve knee balancing in flexion and extension by posterior soft tissue release, 2 knees with Charcot arthritis with severe varus and bone loss, and 1 with traumatic osteoarthritis with severe varus and ligamentous instability. The mean duration of follow-up was 71 months（range 40–90 months）. The New Knee Society scoring（NKSS） system and the Hospital for Special Surgery（HSS） score were used to evaluate the functional and clinical outcomes. Visual Analogue Scale（VAS） was used for pain measurement and Knee Society criteria for evaluation of radiological images. The results showed that, in the total 48 knees, 1 case of loosening due to short-stem tibial component at 3 months post-operatively underwent revision. The 6-year prosthesis survival rate in this cohort was 97.9%. There was no component infection occurring within 6 years. Significant post-operative improvements were found in NKSS and HSS scores. Patient satisfaction was significantly increased. Pain score was decreased significantly. Total functional score was improved from 31.46±11.43 to 86.42±8.87, range of motion（ROM） from 42.42°±23.57° to 95.31°±23.45° and the flexion contracture from 5.31°±7.87° to 0.92°±1.80°. Preoperative radiographic study showed excessive valgus（≥7°） in 37 knees, and varus deformity in 3 knees. Post-operative femorotibial alignment was valgus 3.88°±1.76° in 48 knees. Antero/posterior（A/P） view of X-ray films showed 4 radiolucent lines（RLL） in 48 tibial components. It was concluded that TKA with CCK is effective for the treatment of the severe unstable knee that cannot be balanced by soft tissue.

Modified treatment of knee osteoarthritis complicated with femoral varus deformity:A case report

BACKGROUND Surgical treatment of knee osteoarthritis(KOA)complicated by extra-articular deformity has always been controversial regardless of whether it is simultaneous or staged.Simultaneous total knee arthroplasty(TKA)combined with supracondylar osteotomy without plate for treatment of KOA complicated by femoral varus deformity has not been reported in the literature.CASE SUMMARY A 53-year-old Chinese woman complained of left knee pain for 6 years that worsened for 4 mo during her visit on April 3,2020,accompanied by instability in walking,which seriously affected quality of life.According to her medical history and preoperative imaging,the patient was diagnosed with left KOA with varus deformity.We used the angular center of rotation principle for osteotomy of the femur deformity and placed a poststabilized femur prosthesis into the knee joint.At the same time,a 13 mm×130 mm femur extension rod was used instead of a steel plate to fix the end of the femur osteotomy,reducing the possible complications caused by steel plate implantation and reducing the economic burden on patients.The operation successfully solved two major problems of KOA and varus deformity,and the clinical and imaging evaluation of postoperative followup were satisfactory.CONCLUSION TKA and supracondylar femoral osteotomy can be used for simultaneous KOA treatment and deformity correction.

Three-dimensional printing technology for patient-matched instrument in treatment of cubitus varus deformity:A case report

BACKGROUND Recently,medical three-dimensional printing technology(3DPT)has demonstrated potential benefits for the treatment of cubitus varus deformity(CVD)by improving accuracy of the osteotomy through the use of an osteotomy guide,with or without a patient-mated plate.Here,we present an interesting CVD case,involving a patient who was treated with corrective biplanar chevron osteotomy using an innovative customized osteotomy guide and a newly designed patient-matched monoblock crosslink plate created with 3DPT.CASE SUMMARY A 32-year-old female presented with a significant CVD from childhood injury.A computer simulation was processed using images from computerized tomography scans of both upper extremities.The biplanar chevron osteotomy was designed to create identical anatomy between the mirror image of the contralateral distal humerus and the osteotomized distal humerus.Next,the customized osteotomy guide and patient-matched monoblock crosslink plate were designed and printed.A simulation osteotomy was created for the real-sized bone model,and the operation was performed using the posterior paratricipital approach with k-wire positioning from the customized osteotomy guide as a predrilled hole for screw fixation to achieve immediate control of the reduction after osteotomy.Our method allowed for successful treatment of the CVD case,significantly improving the patient’s radiographic and clinical outcomes,with satisfactory result.CONCLUSION 3DPT-created patient-matched osteotomy guide and instrumentation provides accurate control during CVD correction.

Classification of congenital thumb hypoplasia and deformity

Background:Congenital thumb deformities account for one-third or more of all cases of congenital hand deformity.However,the current classification schemes of congenital thumb hypoplasia are no longer adequate due to their lack of adaptability to increasing knowledge in the field.Hence,a modified system with the potential to adapt to ongoing advances in knowledge and understanding is desperately needed.Methods:Based on the photographs collected from thousands of cases of congenital deformities of the hand and upper limb over multiple decades in our department,we subdivided thumb hypoplasia according to the variables of morphological characteristics,anatomical structures,functional status,the relationship between thumb deformity and hand deformity,the relationship between congenital hand deformity syndrome and thumb hypoplasia,and the selection of treatment methods.Results:A total of 10 types were presented,which were elucidated with nomenclatures as well as pathological feature and symptoms.Conclusion:This modified system may shed additional light on the classification of congenital thumb anomalies,which will assist in a more effective selection of treatment modalities and offers significant benefits to both patients and practice.

Re-revision surgery for re-recurrent valgus deformity after revision total knee arthroplasty in a patient with a severe valgus deformity: A case report

BACKGROUND A recurrent valgus deformity was a common complication after total knee arthroplasty(TKA)in patients with valgus deformity.However,re-revision surgery for re-recurrent valgus deformity after revision TKA in patients with valgus deformity before primary TKA was uncommon.CASE SUMMARY We reported a 72-year-old female patient with two recurrent valgus deformities after TKA for a valgus knee deformity who underwent two revision surgeries to rectify the deformity.In the re-revision surgery,bone defects were successfully reconstructed by the augments and cement in combination with screws and a sleeve.An appropriate neutral alignment of the lower limb was restored by the perfect femoral entry point and the long diaphyseal cementless stem.Adequate fixation of the metaphysis and diaphysis of the femur was obtained by the sleeve and long diaphyseal cementless stem.The patient was pain-free and deformityfree for 2.5 years.CONCLUSION The management of bone defects,the choice of the stem and the femoral entry point were of vital importance in the revision or re-revision TKA for a recurrent valgus deformity.

Deformity frequencies of benthic marine diatoms associated with contaminated sediments in Hong Kong

The relationship between contaminated sediments and deformity frequencies for benthic diatoms was the subject of this study. There were two basic types of diatom deformities observed in this study of Tolo Harbour diatoms: 1. Diatoms with deformed cell wall morphology and 2. diatoms with deformed ornamentation. Deformed individuals of Fragilaria capucina and Achananthes hauckiana Grun. displayed external cell wall deformities while deformed individuals of Diatoma displayed deformities in valve ornamentation. Abnormal cell morphology was used as an indicator of a degraded ecosystem. There was a significant correlation( P <0.05, r s=0.652) between sediment toxicity as reflected by the microtox test and benthic diatom diversity. Species diversity and species richness levels at the twelve sites were closely correlated with one another and inversely correlated with sediment toxicity as reflected by our microtox results( r s=0.809, P <0.01). The microtox test for acute toxicity was correlated ( P <0.05) with diatom species richness. The deformity frequencies and microtox tests were not significantly correlated. This lack of correlation was expected as in numerous laboratory studies, toxic substances were not necessarily mutagenic. The use of diatom deformity frequencies as a means of assessing the mutagenic/teratogenic impacts of anthropogenic substances on a marine benthic diatom community necessitates the enumeration of a large number of diatoms making this method extremely labor intensive.

Volume and fat infiltration of spino-pelvic musculature in adults with spinal deformity

AIM: To investigate fat infiltration and volume of spino-pelvic muscles in adults spinal deformity(ASD) with magnetic resonance imaging(MRI) and 3D reconstructions.METHODS: Nineteen female ASD patients(mean age 60 ± 13) were included prospectively and consecutively and had T1-weighted Turbo Spin Echo sequence MRIs with Dixon method from the proximal tibia up to T12 vertebra. The Dixon method permitted to evaluate the proportion of fat inside each muscle(fat-water ratio). In order to investigate the accuracy of the Dixon method for estimating fat vs water, the same MRI acquisition was performed on phantoms of four vials composed of different proportion of fat vs water. With Muscl'X software, 3D reconstructions of 17 muscles or group of muscles were obtained identifying the muscle's contour on a limited number of axial images [Deformation of parametric specific objects(DPSO) Method]. Musclar volume(Vmuscle), infiltrated fat volume(Vfat) and percentage of fat infiltration [Pfat, calculated as follow: Pfat = 100 ×(Vfat/Vmuscle)] were characterized by extensor or flexor function respectively for the spine, hip and knee and theirs relationship with demographic data were investigated. RESULTS: Phantom acquisition demonstrated a non linear relation between Dixon fat-water ratio and the real fat-water ratio. In order to correct the Dixon fatwater ratio, the non linear relation was approximated with a polynomial function of degree three using the phantom acquisition. On average, Pfat was 13.3% ± 5.3%. Muscles from the spinal extensor group had a Pfat significantly greater than the other muscles groups, and the largest variability(Pfat = 31.9% ± 13.8%, P < 0.001). Muscles from the hip extensor group ranked 2nd in terms of Pfat(14% ± 8%), and were significantly greater than those of the knee extensor(P = 0.030). Muscles from the knee extensor group demonstrated the least Pfat(12% ± 8%). They were also the only group with a significant correlation between Vmuscle and Pfat(r =-0.741, P < 0.001), however this correlation was lacking in the other groups. No correlation was found between the Vmuscle total and age or body mass index. Except for the spine flexors, Pfat was correlated with age. Vmuscle and Vfat distributions demonstrated that muscular degeneration impacted the spinal extensors most.CONCLUSION: Mechanisms of fat infiltration are not similar among the muscle groups. Degeneration impacted the spinal and hip extensors most, key muscles of the sagittal alignment.

Effect of osteoarthritic knee flexion deformity correction by total knee arthroplasty on sagittal spinopelvic alignment in Indian population

BACKGROUND Sagittal alignment of the spine,pelvis,and lower extremities is essential for maintaining a stable and efficient posture and ambulation.Imbalance in any element can result in compensatory changes in the other elements.Knee flexion is a compensatory mechanism for spinopelvic sagittal alignment and is markedly affected in severe knee osteoarthritis(OA).The correction of knee flexion deformity(KFD)by total knee arthroplasty(TKA)can lead to complementary changes in the sagittal spinopelvic parameters(SSPs).AIM To determine the SSP changes in patients with knee OA,with or without KFD undergoing TKA.METHODS The study was conducted in 32 patients who underwent TKA.A neutral standing whole-spine lateral radiograph was performed before surgery and 3 mo after surgery in these patients.Subjects were divided into two groups(Group 1 obtained>10°corrections in KFD;group B obtained<10°correction).The pelvic tilt(PT),pelvic incidence(PI),sacral slope(SS),lumbar lordosis(LL),and sagittal vertical axis(SVA)were measured.RESULTS The median of change in PT,PI,SS,LL,and SVA was 0.20 mm,1.00 mm,2.20 mm,−0.40 mm,and 6.8 mm,respectively.The difference in the change in SSPs between the two groups was statistically non-significant.CONCLUSION SSPs,such as PI,PT,SS,LL,and SVA,do not change significantly following TKA in end-stage knee OA despite a significant correction(>10°)in KFD.

Single-Shot 360-Degree Cranial Deformity Detection System Using Digital Image Correlation

In this paper,a single-shot 360-degree cranial deformity detection system using digital image correlation(DIC)is presented to quickly obtain and detect accurate 3D data of infants’cra-nium.By introducing plane mirrors into a stereo 3D DIC measurement system,a multi-view 3D imaging model is established to convert 3D data from real and virtual perspectives into 360-degree 3D data of the tested infant cranium,achieving single-shot and panoramic 3D measurement.Exper-imental results showed that the performance and measurement accuracy of the proposed system can meet the requirements for cranial deformity detection,which provides a fast,accurate,and low-cost solution medically.

The impact of individualized care after artificial knee replacement surgery for patients with valgus deformity of the knee

Objective:To evaluate the perioperative nursing of total knee arthroplasty for patients with valgus deformity of the knee.Methods:Seventy-six patients who underwent surgical treatment were enrolled in the study from March 2014 to March 2018.The patients in the control group were treated with routine nursing.The experimental group was treated not only with routine nursing but also with health education,psychological care,family social support,and other nursing intervention.Hospital for special surgery and Pittsburgh sleep quality index were used to evaluate the effect of nursing intervention on patients after operation.Results:All the index scores of the experimental group were lower than those of the control group(P<0.05),indicating that the function of the diseased limb and the patient's sleep status improved significantly after the intervention.Conclusions:Individualized nursing can improve the recovery of limb function and improve the patients'quality of life.It is very effective for nurses to implement individualized nursing measures for patients after surgery.
