Treatment of Children’s Shaft Fracture of Tibia and Fibula with ESIN Fixation

The Objective is to evaluate Elastic Stable Intrame-dullary Nailing (ESIN) fixation through the treat-ment of children’s shaft fracture of tibia and fibula. From January 2007 to January 2009, 16 cases of children’s shaft fracture of tibia and fibula had been treated by ESIN. 15 cases were followed up after the surgery and the follow-up time was 4 - 12 months (4.5 in average). The results turn out that all the patients’ fractures have got healed by Phase I and the healing time is 10 weeks in average. The near joints’ activity and affected extremity completely return to normal. This group of cases doesn’t show any sign of infection, bone nonunion, malunion or epiphysis injury. And six patients have had their intramedullary nails taken out after six months. It can be concluded that ESIN is good for treating children’s long diaphysis fracture which has difficulty in closed diaplasis and is suitable for children aged 6 - 13. ESIN has the advantages of small incision, slight injury of soft tissue, short sur-gery time, rapid recovery and few complications.

Locking plates for distal fibula fractures in young and elderly patients:A retrospective study

BACKGROUND Ankle fractures are common injuries in the young and elderly populations.To prevent post-traumatic arthritis,an anatomic reconstruction of the ankle structure is mandatory.Open reduction and internal fixation is the treatment of choice among orthopaedics.Conventional plates allow stability of the fracture if bone quality is present.Locking plates might offer an advantage for the treatment of lateral malleolar fracture in patients with comminution,severe instability,distal fractures,or osteoporotic bone.Our hospital introduced a new locking plate for fracture of the distal fibula.AIM To evaluate locking plates in terms of outcomes and complications in young and elderly patients.METHODS We retrospectively reviewed a total of 67 patients treated for displaced distal fibula fractures.Demographic data,number of comorbidities,use of inter fragmentary screw,complication,time of fracture healing,partial or full weight bearing,and reoperation were recorded for all patients.Clinical outcome was assessed by the American Orthopedic Foot and Ankle Society clinical scoring system.Radiographs were obtained at 4,8,12,16,20,and 24 wk until radiographic union was obtained.RESULTS All patients displayed complete bony union on radiographic assessment,and no patients developed any serious complications.We observed two superficial infections,one delayed wound healing,and two plate intolerances.Significant differences were observed between the two age groups in terms of radiographic healing(11.9 wk in younger patients vs 13.7 wk in older patients;P=0.011)and in the American Orthopedic Foot and Ankle Society score at 6 mo after surgery(88.2 in younger patients vs 86.0 in older patients;P=0.001)and at 12 mo after surgery(92.6 in younger patients vs 90.0 in older patients;P=0.000).CONCLUSION Locking plates provide a stable and rigid fixation in multifragmentary and comminuted fractures or in the presence of poor bone quality.

Outcomes of early versus late irrigation and debridement of pediatric open long bone fractures

BACKGROUND Open long bone fractures are a major concern for pediatric patients due to the risk of surgical site infection(SSI).Early studies have recommended irrigation and debridement of open fractures within 6 hours-8 hours for the prevention of SSI.According to the American College of Surgeons(ACS)Best Practice Guidelines,in 2015,irrigation and debridement should be done within 24 hours.AIM To identify whether early irrigation and debridement,within 8 hours,vs late,between 8 hours and 24 hours,for pediatric open long bone fractures impacts rate of SSI.METHODS Using retrospective data review from the National Trauma Data Bank,Trauma Quality Improvement Project(TQIP)of 2019.TQIP database is own by the ACS and it is the largest database for trauma quality program in the world.Propensity matching analysis was performed for the study.RESULTS There were 390 pediatric patients with open long bone fractures who were incl-uded in the study.After completing propensity score matching,we had 176 patients in each category,irrigation and debridement within 8 hours and irrigation and debridement between 8 hours and 24 hours.We found no significant differences between each group for the rate of deep SSI which was 0.6%for patients who received surgical irrigation and debridement within 8 hours and 1.1%for those who received it after 8 hours[adjusted odd ratio(AOR):0.5,95%CI:0.268-30.909,P>0.99].For the secondary outcomes studied,in terms of length of hospital stay,patients who received irrigation and debridement within 8 hours stayed for an average of 3.5 days,and those who received it after 8 hours stayed for an average of 3 days,with no significant difference found,and there were also no sig-nificant differences found between the discharge dispositions of the patients.CONCLUSION Our findings support the recommendation for managing open long bone fractures from the ACS:Complete surgical irrigation and debridement within 24 hours.

Functional Outcomes of Adult Tibia Shaft Fractures Treated with Solid Intramedullary Nails versus Hollow Nails: A Systematic Review

Introduction: The management of fractures of the tibia shaft is an important aspect of orthopaedic care, and the selection of the surgical method for fixation can substantially impact patient outcomes. The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.

Relationship between serum adhesion molecules, trace elements and delayed union of tibial and fibula fractures

Objective:To investigate the relationship between serum adhesion molecules, trace elements and delayed union of tibial and fibula fractures.Methods:A total of 46 patients with delayed union of tibial and fibula fractures in our hospital from May 2014 to June 2016 were selected as the observation group, 46 patients with normal healing of tibial and fibula fractures were selected as the control group, then the serum adhesion molecules and trace elements levels of two groups at forth, eighth and sixteenth week after the surgery were compared.Results:The serum dhesion molecules levels of observation group at forth, eighth and sixteenth week after the surgery were all higher than those of control group, the serum trace elements levels were all lower than those of control group, and the serum adhesion molecules levels of two groups at eighth week after the surgery were all higher than those at other time, the trace elements levels were all lower than those at other time (allP<0.05).Conclusions:The serum adhesion molecules and trace elements of patients with delayed union of tibial and fibula fractures show obviously abnormal state, so those indexes of those patients should be paid to more monitoring and improvement.

Total knee arthroplasty and fractures of the tibial plateau

Tibial plateau fractures are common injuries that occur in a bimodal age distribution. While there are various treatment options for displaced tibial plateau fractures, the standard of care is open reduction and internal fixation(ORIF). In physiologically young patients with higher demand and better bone quality, ORIF is the preferred method of treating these fractures. However, future total knee arthroplasty(TKA) is a consideration in these patients as post-traumatic osteoarthritis is a common long-term complication of tibial plateau fractures. In older, lower demand patients, ORIF is potentially less favorable for a variety of reasons, namely fixation failure and the need for delayed weight bearing. In some of these patients, TKA can be considered as primary mode of treatment. This paper will review the literature surrounding TKA as both primary treatment and as a salvage measure in patients with fractures of the tibial plateau. The outcomes, complications, techniques and surgical challenges are also discussed.

Experimental and finite element analysis of tibial stress fractures using a rabbit model

AIM: To determine if rabbit models can be used to quantify the mechanical behaviour involved in tibial stress fracture(TSF) development.METHODS: Fresh rabbit tibiae were loaded under compression using a specifically-designed test apparatus. Weights were incrementally added up to a load of 30 kg and the mechanical behaviour of the tibia was analysed using tests for buckling, bone strain and hysteresis. Structural mechanics equations were subsequently employed to verify that the results were within the range of values predicted by theory. A finite element(FE) model was developed using cross-sectional computer tomography(CT) images scanned from one of the rabbit bones, and a static load of 6 kg(1.5 times the rabbit's body weight) was applied to represent running. The model was validated using the experimental strain gauge data, then geometric and elemental convergence tests were performed in order to find the minimum number of cross-sectional scans and elements respectively required for convergence. The analysis was then performed using both the model and the experimental results to investigate the mechanical behaviour of the rabbit tibia under compressive load and to examine crack initiation.RESULTS: The experimental tests showed that un der a compressive load of up to 12 kg, the rabbit tibia demonstrates linear behaviour with little hysteresis Up to 30 kg, the bone does not fail by elastic buckling however, there are low levels of tensile stress which predominately occur at and adjacent to the anterio border of the tibial midshaft: this suggests that fatigue failure occurs in these regions, since bone under cycli loading initially fails in tension. The FE model predic tions were consistent with both mechanics theory and the strain gauge results. The model was highly sensi tive to small changes in the position of the applied load due to the high slenderness ratio of the rabbit s tibia. The modelling technique used in the curren study could have applications in the development o human FE models of bone, where, unlike rabbit tibia the model would be relatively insensitive to very sma changes in load position. However, the rabbit mode itself is less beneficial as a tool to understand the me chanical behaviour of TSFs in humans due to the sma size of the rabbit bone and the limitations of human scale CT scanning equipment.CONCLUSION: The current modelling technique could be used to develop human FE models. However, the rabbit model itself has significant limitations in under standing human TSF mechanics.

Ipsilateral femur and tibia fractures in pediatric patients:A systematic review

AIM To better understand how pediatric floating knee injuries are managed after the wide spread use of new orthopaedic technology.METHODS We searched EMBASE, COCHRANE and MEDLINE computerized literature databases from the earliest date available in the databases to February 2017 using the following search term including variants and pleural counterparts: Pediatric floating knee. All studies were thoroughly reviewed by multiple authors. Reference lists from all articles were scrutinized to identify any additional studies of interest. A final database of individual patients was assembled from the literature. Univariate and multivariate statistical tests were applied to the assembled database to assess differences in outcomes.RESULTS The English language literature contains series with a total of 97 pediatric patients who sustained floating knee injuries. Patients averaged 9.3 years of age and were mostly male(73). Approximately 25% of the fractures were open injuries, more tibia(27) than femur(10). Over 75% of the fractures of both the tibia and the femur involved the diaphysis. More than half(52) of the patients were treated non-operatively for both fractures. As a sequela of the injury 32(33%) patients were left with a limb length discrepancy, 24(25%) patients had lengthening of the injured limb at follow up, while 8(8%) had shortening of the affected limb. Infection developed in 9 patients and 3 had premature physeal closure. Younger patients were more likely to be treated non-operatively(P < 0.001) and patients treated with operative intervention had statistically significant shorter hospital length of stays(P = 0.001).CONCLUSION Given the predominance of non-operative managementin published studies, the available literature is not clinically relevant since the popularization of internal fixation for pediatric long-bone

Comparative efficacy of ketamine,lidocaine,acetaminophen,and dexmedetomidine combined with morphine patient-controlled analgesia in treating opium-addicted patients undergoing tibia fracture surgery:A randomized clinical trial

Objective:To compare the effect of ketamine,lidocaine,acetaminophen,and dexmedetomidine combined with morphine patient-controlled analgesia for opium addicts after tibial fracture surgery.Methods:This double-blind clinical trial included opium-addicted patients undergoing tibia fracture surgery.Patients were recruited and randomized to four different groups including the ketamine group,the lidocaine group,the acetaminophen group,and the dexmedetomidine group.The hemodynamic parameters such as heart rate(HR),mean arterial pressure,and arterial SaO2,alongside visual analog scale pain scores,sedation assessed by Ramsay score,nausea and vomiting,and opioid use were recorded and compared among the four groups.Results:This study included 140 patients,aged 37(32,41)years,with 92 males and 48 females,and each group had 35 patients.Dexmedetomidine-sedated subjects had the lowest blood pressure from 1 to 24 h after surgery,decreased HR at 12 and 24 h after surgery,and more satisfactory sedation(P<0.05).Notwithstanding no significant difference was noted in the pain scores,or nausea and vomiting among the groups(P>0.05).Conclusions:Dexmedetomidine has a better sedation effect compared to ketamine,lidocaine,and acetaminophen for pain control,but the final choice hinges on the patients’physical condition and the anesthesiologist's preference.Clinical registration:It is registered in Iranian Registry Clinical Trial by code IRCT20141209020258N146.

Strategies and outcomes in severe open tibial shaft fractures at a major trauma center: A large retrospective case-series

BACKGROUND Severe open tibia fractures are challenging to treat with a lack of published clear management strategies.Our aim was to provide an overview of the largest singlecenter experience in the literature,with minimum 1-year follow-up,of adult type 3 open tibial shaft fractures at Cambridge University Hospitals(a United Kingdom major trauma center).We sought to define patient characteristics and our main outcome measures were infection,union and re-fracture.AIM To retrospectively define patient and injury characteristics,present our surgical methods and analyze our outcomes–namely infection,union and re-fracture rates.METHODS Consecutive series of 74 patients with 75 open tibial fractures treated between 2014 and 2020(26 classified as Gustilo-Anderson 3A,47 were 3B and two were 3C).Nine patients underwent intramedullary nailing(IMN),61 underwent Taylor spatial frame(TSF)fixation and 5 were treated with Masquelet technique(IMN and subsequent bone grafting).RESULTS Mean follow-up was 16 mo(IMN)and 25 mo(TSF).We had an infection rate of 6.7%(5),non-union rate of 4%(3)and re-fracture rate of 2.7%(2).Average time to union was 22 wk for IMN and 38.6 wk for TSF.Thirty-three cases had a bone defect with a mean of 5.4 cm(2-11).Patient age,sex,diabetes,smoking status or injury severity did not have a significant effect on union time with either fixation method.Our limb salvage rate was 98.7%.CONCLUSION Grade 1 to 3A injuries can effectively be treated with reamed or unreamed IMN.Grade 3B/C injuries are best treated by circular external fixators as they provide good,reproducible outcomes and allow large bone defects to be addressed via distraction osteogenesis.

To assess the effect of using buttress plate associated with antografting of fibula and iliac bone for the treatment of distal femoral C3 type fracture.Methods Seventeen cases of distal femoral C3 type fracture using buttress plate associated with antografting of fibula and iliac bone were analyzed retrospectively.Results All cases were followed up for an average of 24 months（8～55 months）.The average time of octets bridge forming were 4 months（3～5 months） while the average time for bone union were 8 months （6～14 months）.According to Shelbourne rating system,result of all 18 cases were excellent and no malunion,infection were found.Conclusion Buttress plate associated with antografting of fibula and iliac bone is an effective alternative for the treatment of distal femoral C3 type fracture.It can provide more stable fixation to the bone and earlier functional exercises can be achieved.5 refs,3 figs,1 tab.

Minimally invasive percutaneous plate osteosynthesis through fracture site approach for fracture of both tibia and fibula

Objective:To introduce the experience of treating fracture of both tibia and fibula with micro-invasive percutaneous plate internal fixation through fracture site approach. Methods:The data of 15 patients(11 males and 4 females),including 14 adults(aged 22-73 years,mean=40 years)and 1 child(aged 10 years),with fracture of both tibia and fibula were studied retrospectively in this study.A small incision was made at the fracture site of tibia.Then reposition was made under direct vision,and internal fixation was employed with steel plates inserting through the small incision. Results:Anatomical reduction was obtained.No complication was found.Union occurred on time in 14 patients.One case healed after a second operation. Conclusions:Micro-invasive percutaneous plate internal fixation is beneficial to the healing of bone and soft tissues.Without X-ray examination,it is also easy to reach anatomical reduction and make tibial internal fixation with both plates with micro-invasive percutaneous plate internal fixation.

Correlative Factors Research of Tibial Shaft Fracture with Ipsilateral Posterior Malleolar Crack Fractures

Background:Missed diagnosis rate of spiral tibia shaft fracture with posterior malleolus crack fracture(PMCF)is high in the clinical.However,the mechanism and related factors of fracture are still unclear.Moreover,PMCF has been observed in other types of tibial shaft fractures.Objective:To explore the correlative factors of tibial shaft fracture with ipsilateral PMCF,decrease the rate of clinical missed diagnosis,strengthen the effective fixation of PMCF,and reduce the incidence of traumatic arthritis.Methods:From September 2014 to May 2019,we collected 137 tibiofibular fracture.Only 68 cases involved in ankle joint CT examination and were retrospectively analyzed.The patients were divided into posterior malleolus group(30 cases)and non-posterior malleolus group(38 cases)according to whether come up PMCF or not.The posterior malleolus group contained 24 males and 6 females,27-77(47.57±11.79)years old,the non-posterior malleolus group contained 23 males and 15 females,18-85(48.71±13.84)years old.The gender,age,location,fibula fracture and tibial shaft fracture classification were observed for univariate and multivariate analysis.Results:The probability of PMCF was higher with right tibial shaft fracture(OR=3.6995%CI:1.13-12.08 P<0.05);the probability of PMCF following distal fibular fracture was higher than that without fibular fracture(OR=11.3695%CI:1.72-75.05 P<0.05);the probability of PMCF with type A tibial shaft fracture was higher than type C(OR=4.8295%CI:1.19-19.58 P<0.05).Conclusion:Right type A tibial shaft fracture accompanied by distal fibular fracture are very important factors related to PMCF,which needs highly attention to avoid clinical missed diagnosis.

Stature Estimation Based on the Length of Tibia and Fibula Measured by Digital X-ray in Chinese Han Teenagers

Objective To derive regression formulae for stature estimation using forensic radiography from the tibia and fibula of Chinese Han teenagers in Sichuan Province. Methods To construct equations, measurements were conducted on the training sample (412 adults, 201 males and 211 females). The whole length of the fibula and four measurements of tibia were determined using CR radiography, rectified through theoretical magnification. The regression formulae were relatively constructed to the real stature measured in an erect position. Through using the testing sample (40 adults) for the regression formulae, the reliability of the regression formulae was assessed. Results The range of correlation coefficients of four measurements for tibia was 0.880-0.895 in the sex-unknown group, 0.869-0.893 in the male, and 0.8450.855 in the female. The five measurements were found to be better correlated with stature in the male than in the female. Conclusion The digital X-ray of the tibia and fibula for stature estimation is proved to be effective in forensic individual identification; therefore, these equations can be of great assistance to the stature estimation of the contemporary Chinese Han teenagers.

Treatment of Non-union Femoral Neck Fractures with Vascularized Fibula Grafting

Objective: To investigate the value of transplantation of vascularized fibula in treating non-union femoral neck fractures and preventing ischemic necrosis of the femoral head. Methods : Vascularized heterotopic fibula was transplanted to the anterior-lateral part of the femoral neck. The fibula artery and vein were anastomosised with lateral circumflex artery and vein. Results : One hundred and twenty-nine cases of non-union femoral neck fracture were treated with vascularized fibula graft in our hospital from 1982 to 2002. Eighty-seven cases of them were followed up for 3 to 19 years with functional and X-ray examination. The percentage of fracture healing and effect were 94. 3 and 81. 6, respectively. Conclusion:The fibula with blood supply has a synergistic fixation impact on the non-union femoral neck fractures. The fibula is solid enough for supporting the femoral head and preventing it from collapse. The vascularized fibula grafting, by providing blood supply to the affected femoral head and neck, could promote the femoral head restoration and reconstruction. In addition, the periosteum of fibula plays a role in fracture healing.

Ankle Arthrodesis Nail Combined with Locking Compression Plate to Stabilize Two-Level Pathologic Tibial Fractures

Treatment of fragility fractures of the distal tibia in the elderly is demanding because of osteopenic bone quality, the delicate soft tissue cuff and frequent critical circulation. We report the case of two-level tibial pseudarthroses in an 83- year-old woman caused by multiple myeloma successfully stabilized by a long ankle arthrodesis nail combined with locking compression plate osteosynthesis. This case is unique, as to our best knowledge, herein diaphyseal fractures were treated for the first time using a technique reported hitherto primarily for fragility ankle and pilon fractures.

Distal Tibial Stress Fracture Secondary to Severe Osteoarthritis Knee

Stress fractures of the tibia are commonly seen in young athletes or military recruits due to repetitive micro trauma. These are rare in elderly patients. Osteoarthritis knee with varus deformity leading to stress fracture is rare but has been reported in literature. Stress fracture in osteoarthritis more commonly occurs in upper third tibia. We report a patient who had stress fractures of distal tibial shaft secondary to advanced osteoarthritis of knee with varus deformity.

Simultaneous, Asymmetrical, Comminuted and Bilateral Ballistic Fractures by Multiple Gunshot Wounds and a Review of Its Literature: A Case Report in Chad

Although open leg fractures are very common in orthopedics and traumatology, bilateral open leg fractures are extremely rare and are usually associated with an increased risk of complications. We report a case of a simultaneous, asymmetrical, comminuted and bilateral open fracture of the tibia and fibula by a firearm that occurred during an escape attempt in a 29-year-old prisoner. The pre-operative radiological assessment found an open fracture of both legs of the ballistic type;multiple traumatic gunshot wounds with a narrow entry hole and a wide exit hole. Early surgical intervention of intravenous antibiotics, tetanus prophylaxis and open fracture irrigation and debridement was performed within the 6 hour rule. The treatment consisted of a posterior splint followed by trimming andosteosynthesis using a FESSA external fixator from the military health service. A second operation was not needed. Evolution was favorable with ambulation starting from the 45th day. Simultaneous and bilateral tibia-fibula fractures by a firearm are exceptional, therefore, the treatment was surgical with the pre-operative and post-operative protocols well managed.

Systematic review of periprosthetic tibia fracture after total knee arthroplasties

AIM: To investigate the known incidences, treatment options, and related outcomes of periprosthetic tibia fractures after total knee arthroplasty(TKA).METHODS: A literature search was done to identify studies that fit the inclusion criteria. The database search yielded 185 results, which were further reduced by the exclusion criteria to 13 papers, totaling 157 patients that met these criteria. Incidence rates of the different types of periprosthetic tibia fractures were determined and their treatments were subsequently analyzed based on the fracture's subclass, with patient outcomes being overall favorable.RESULTS: Of the 144 documented patients, 54(37.5%) had a subclass C fracture, which are frequently seen in revision arthroplasties or when using cement intraoperatively. The fractures of subclasses A and B occur postoperatively. There were 90 subclass A and B fractures with incidences of 18.75% and 43.75% respectively. When broken down by type, 62(55.36%) were type 1, 24(21.4%) were type 2, 24(21.4%) were type 3, and 2(1.8%) were type 4. Furthermore, from the studies that included origin of injury, the types were further classified as having non-traumatic or traumatic origins. Type 1 had 78%(40/51) non-traumatic origin and 22%(11/51) traumatic origin. Fifteen fractures were type 2, but 5 were falls and 1 through a motor vehicle accident, giving a trauma causation of 40%(6/15). Of the 24 type 3 fractures, 12 were falls and 2 vehicular accidents, leading to a trauma causation of 58%(14/24).CONCLUSION: Type 1 fractures were the most common. Subclass A was treated with locking plates, B required a revision TKA, and C was treated intraoperatively or nonoperatively.
