Distal femur complex fractures in elderly patients treated with megaprosthesis:Results in a case series of 11 patients

BACKGROUND Surgical treatment of complex fractures of the distal femur in the elderly is controversial.Osteoporosis and pre-existent osteoarthritis are common comorbidities in the elderly which add to the need for early walking and rapid restoration of function and also pose significant obstacles to achievement of satisfactory results with standard fixation techniques.Recently,several authors have suggested that primary arthroplasty could be a viable alternative option to standard fixation techniques in selected patients with complex distal femur fractures.AIM To present our experience with 11 cases of distal femur fractures treated with knee arthroplasty and large femoral resection in a population of patients over the age of 85.METHODS Data from 11 consecutive patients(10 females,1 male)presenting with acute intra-articular supracondylar or intercondylar distal femur fractures and with pre-existent primary osteoarthritis who were treated with primary knee arthroplasty were recorded.We collected standard demographic data,comorbidities and patient reported outcomes including Visual Analogical Scale(VAS),Oxford Knee Score(OKS)and Barthel’s Index.Post-operative joint range of motion(ROM)and standard radiographic data were also collected.RESULTS At a mean follow-up of 23.2 mo,all of the implants were well-positioned and osteointegrated.Furthermore,all the patients were alive and walking either independently or with walking aids.There was a marked improvement in pain(VAS 4.5 postop vs 1.9 at the last follow-up),OKS score(29.5 postop vs 36.81 at the last follow-up),ROM(96.2°postop vs 102°at the last follow-up)and restoration of pre-injury ambulatory status(average Barthel Index 77.3).The radiographic evaluations showed good restoration of the articular geometry.No deaths and no complications were recorded.CONCLUSION In conclusion,we believe that knee megaprosthesis in the case of complex fractures of the distal femur is a valid surgical choice.This is particularly true in elderly patients with severe osteoporosis and pre-existing osteoarthritis.It is important to note that this surgery should be performed by surgeons with proven experience in prosthetic hip and knee surgery and that a scrupulous selection of the cases is completed.

Surgical Treatment of Recent Traumatic Epiphyseal Detachments of the Distal Femur in the Orthopedic and Traumatological Surgery Department of the CHU Bocar Sidy Sall de Kati: About 20 Cases

Introduction: To our knowledge, no scientific study has been conducted at the university hospital of Kati on recent traumatic epiphyseal detachment fractures of the distal femur. However, every day, children present in consultation for knee trauma. Conjugal plate fractures are by definition single to children. Any break in any solution of continuity of this plate is called an epiphyseal fracture or detachment. Objectives: To evaluate the results of surgical treatment of traumatic epiphyseal in detachments of the distal femur recent in children and adolescents. Patients and Method: This was a 13-month prospectively collected longitudinal descriptive study from September 1, 2016 to September 30, 2017. We identified and reviewed 20 medical records of recent traumatic epiphyseal detachments of the distal femur. The parameters studied were sociodemographic, lesion, surgical technique and evolutionary. Results: During the study period, the most affected group age was 12 to 17 years (85%) with an average of 14.65 ± 1.61 years (6 and 20 years). The victims were male (95%). The most frequent etiology was road traffic accident (95%), with a mean time to care of 26.42 ± 10.21 hours and Type II was frequently encountered (85%) with 35% of immediate complications. Cross-bracketing was the most commonly used surgical technique (85%). The result was good (65%). Conclusion: This study allowed us to observe a significant hospital incidence of epiphyseal detachment fractures of the distal femur. Cross pinning was the most commonly used surgical technique with fewer complications (35%) and a satisfactory result in 90% of cases.

Treatment of distal femur fractures in a regional Australian hospital

AIM:To review our outcomes and compare the results of the Less Invasive Stabilization System(LISS)to other implants for distal femur fracture management at a regional Australian hospital.METHODS:The LISS is a novel implant for the management of distal femur fractures.It is,however,technically demanding and treatment results have not yet been assessed outside tertiary centres.Twenty-seven patients with 28 distal femur fractures who had been managed surgically at the Mackay Base Hospital from January 2004 to December 2010 were retrospectively enrolled and assessed clinically and radiologically.Outcomes were union,pain,Lysholm score,knee range of motion,and complication rates.RESULTS:Twenty fractures were managed with the LISS and eight fractures were managed with alternative implants.Analysis of the surgical techniques re-vealed that 11 fractures managed with the LISS were performed according to the recommended principles(LISS-R)and 9 were not(LISS-N).Union occurred in67.9%of fractures overall:9/11(82%)in the LISS-R group vs 5/9(56%)in the LISS-N group and 5/8(62.5%)in the alternative implant group.There was no statistically significant difference between pain,Lysholm score,and complication rates between the groups.However,there was a trend towards the LISS-R group having superior outcomes which were clinically significant.There was a statistically significant greater range of median knee flexion in the LISS-R group with compared to the LISS-N group(P=0.0143)and compared with the alternative implant group(P=0.0454).CONCLUSION:The trends towards the benefits of the LISS procedure when correctly applied would suggest that not only should the LISS procedure be performed for distal femur fractures,but the correct principle of insertion is important in improving the patient’s outcome.

Reliability of the pronator quadratus fat pad sign to predict the severity of distal radius fractures

AIM To evaluate the reliability of pronator quadratus fat pad sign to detect distal radius fracture and to predict its severity.METHODS Retrospectively we identified 89 consecutive patients(41 female, mean age 49 ± 18 years) who had X-ray(CR) and computed tomography(CT) within 24 h following distal forearm trauma. Thickness of pronator quadratus fat pad complex(PQC) was measured using lateral views(CR) and sagittal reconstructions(CT). Pearson's test was used to determine the correlation of the PQC thickness in CR and CT. A positive pronator quadratus sign(PQS) was defined as a PQC > 8.0 mm(female) or > 9.0 mm(male). Frykman classification was utilized to assess the severity of fractures.RESULTS Forty-four/89 patients(49%) had a distal radius fracture(Frykman Ⅰ n = 3, Ⅱ n = 0, Ⅲ n = 10, Ⅳ n = 5, Ⅴ n = 2, Ⅵ n = 2, Ⅶ n = 9, Ⅷ n = 13). Mean thickness of the PQC thickness can reliably be measured on X-ray views and was 7.5 ± 2.8 mm in lateral views(CR), respectively 9.4 ± 3.0 mm in sagittal reconstructions(CT), resulting in a significant correlation coefficientof 0.795. A positive PQS at CR was present in 21/44 patients(48%) with distal radius fracture and in 2/45 patients(4%) without distal radius fracture, resulting in a specificity of 96% and a sensitivity of 48% for the detection of distal radius fractures. There was no correlation between thickness of the PQC and severity of distal radius fractures.CONCLUSION A positive PQS shows high specificity but low sensitivity for detection of distal radius fractures. The PQC thickness cannot predict the severity of distal radius fractures.

A Novel Method to Fix Type C3 Distal Femur Fractures with Bone Defect Loss Using “Harms Cage”

A case of compound C3 distal femur fracture with 12 cm bone defect. After thorough debridement, the Harms cage was used to reconstruct the medial column and the fracture was fixed with the locking distal femur plate laterally. The Harms cage prevents the cantilever effect and eliminates the need for medial plating. This avoids another medial incision and preserves medial biology. At 18 months’ follow-up, plain radiographs demonstrated full reconstruction of the medial column with good range of motion at the knee joint. This technique avoids the need of dual plating in these fractures with good results.

Ligamentotaxis versus Open Reduction and Internal Fixation for Distal Radius Intra-Articular Fractures

Objectives: This study compared the clinical and radiological outcomes of two different methods for the treatment of distal radial intra-articular fractures. Patients and Methods: Forty-six patients with distal radius intra-arti-cular fractures were divided into two groups. Group I included 24 patients with type C fracture treated by external fixator augmented by percutaneous K-wires. Group II included 22 patients with type C fracture treated by volar locked distal radial plate augmented by K-wires. Two patients had complex injuries necessitating double plating (sandwich). All patients were evaluated clinically by Mayo Wrist Score and radiologically by Sarmiento’s radiological score. Results: Both groups reported good personal satisfaction according to Mayo Wrist Score, and the results were not statistically different between the two groups. In Group I, 19 patients (79.2%) had excellent radiological outcome and five patients (20.9%) had good radiological outcome according to Sarmiento’s radiological score. In Group II, 20 patients (90.9%) had excellent outcome, and two (9.1%) had good radiological outcome;there was no or insignificant deformity. Conclusions: Complex distal radial fractures can be treated either by external fixation (ligamentotaxis) or by locked pre-contoured plating. The clinical outcome of plating and external fixator in our study did not show any statistically significant difference. The radiological outcome had no correlation with the clinical outcome.

Total knee arthroplasty for treatment of post-traumatic arthritis: Systematic review

AIM To review and report functional outcomes, complications,and survivorship associated with total knee arthroplasty(TKA) in the treatment of post-traumatic arthritis(PTA).METHODS We conducted a systematic review according to the PRISMA guidelines. We searched PubMed, Cochrane Library, and SCOPUS in December 2015 for Englishlanguage clinical research studies, both prospective and retrospective, examining the use of TKA for the treatment of PTA. All relevant articles were accessed in full. The manual search included references of retrieved articles.We extracted data on patients' demographics and clinical outcomes, including preoperative diagnosis and pre- and post-operative functional scores. We summarized the data and reported the results in tables and text.RESULTS Sixteen studies, four prospective and ten retrospective,examined patients who underwent TKA for PTA due to fractures of the proximal tibia, patella, and/or distal femur. Eleven studies utilized the Knee Society Scores criteria to assess functional outcomes. All studies utilizing these criteria reported an improvement in functional and knee scores of patients following TKA. Further, studies reported an increased range of motion(ROM) and reduction of pain following surgery. The most commonly reported complications with TKA included infection, stiffness, wound complications, intraoperative rupture of tendons, and osteolysis/polyethylene wear. The overwhelming majority of these complications occurred within the first two years following surgery. Six studies examined the survivorship of TKA with subsequent revision for any reason as an endpoint. Compared to patients with osteoarthritis, patients with PTA required more revisions, the majority for polyethylene wear.CONCLUSION Although associated with higher complication rates,TKA is an effective treatment for PTA, as it improves ROM, pain and functional outcomes.

Evaluation of results of open distal femur fractures with primary fixation and antibiotic impregnated collagen

Purpose:Distal femoral fracture is one of the most common lower limb injuries and accounts for less than 1%of all fractures.Open fracture takes 5%-10%of the all distal femoral fractures,which is at an increased risk of complications.There were limited studies which documented the outcomes of such cases.The present study aims to evaluate the outcome and complications in these fractures using primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement.Methods:This is a prospective study conducted in a tertiary care orthopaedic hospital in northern India.Thirty patients of open distal femoral fractures were managed by primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement.They were followed for minimum of six months.Patients were followed up monthly for first four months,at six months and one year after surgery.Clinical and radiological signs of healing,any complications,time to union,and functional outcome were assessed.Results:The mean age of patients was 44.33 years(range 20-82 years)with male predominance of 66.7%.According to Gustilo-Anderson classification,there were 5,15 and 10 patients with open grade I,II and IIIA distal femoral fractures respectively.According to orthopaedic trauma association(OTA)classification,majority of patients in our study were of C3 type.The mean time to bony union was 5.6 months(range 4-9 months).Average postoperative knee range of motion(ROM)at the latest follow-up was 98°(range 70°-120°).Lysholm knee scoring scale showed excellent score in 11 patients,good in 9 patients,fair and poor in 5 patients each;however,there was no significant correlation with fracture pattern types(p<0.05).Knee stiffness was the major complications encountered in the study.The knee ROM was<90°in 5 patients and 90°-120°in rest of the patients,while 1 patient had extensor lag of 10°.One patient had implant failure and lost to follow-up;3 patients had deep infection.Conclusion:An approach of primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to early aggressive debridement in open distal femur fractures shows significant results in terms of functional and radiological outcomes with minimal complications.
