Hybrid External Fixation for Open Severe Comminuted Fractures of the Distal Femur

Background: The treatment of distal femoral open comminuted fractures is a major problem for orthopedic surgeon. The basic and important aim in treatment of these fractures is to assemble the condylar fragments and then fix the condyles to the femoral shaft by minimum handling of the bone and soft tissues. Objectives: To evaluate the treatment of distal femoral open comminuted fractures (type C2 and C3) with hybrid external fixator. Methods: Thirty-four patients with distal femur open comminuted fracture (type C2 and C3) were treated by hybrid external fixator between January 2005 and December 2008. All of the fractures were opened with extension to joint surface. 30 patients were male and 4 were female. Their average age was 30.5 years (17 to 72 years). Average follow up period was 36 months. 12 patients had isolated fracture and 22 patients had multiple fractures. The bony and functional results were evaluated by the association for the study and application of the method of Ilizarov (ASAMI) protocol and knee society score. Results: 29 out of 34 fractures (85%) had union without bone grafts. Average time of union was 6.1 months (4 - 19 ms). The average knee range of motion was 87.5 degrees (30 - 115 degrees). The bony results were excellent in 24 patients (70.5%), good in 6 (17.7%), fair in 2 (5.9%), and poor in 2 (5.9%), and the functional results were excellent in 10 (29.4%) patients, good in 14 (41.2%), fair in 6 (17.6%), and poor in 4 (11.8%), and the functional results were excellent in 10 (29.4%) patients, good in 14 (41.2%), fair in 6 (17.6%), and poor in 4 (11.8%) according to ASAMI protocol. According to the knee society score the functional results were excellent in 9 (26.44%) patients, good in 13 (38.26%), fair in 7 (20.6%), and poor in 5 (14.7%). Conclusion: Hybrid external fixator is an effective method for treatment of distal femoral open comminuted fractures (type C2 and C3) and may be considered as an alternative surgical methods in the management of these fractures.

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.

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.

Managing extremely distal periprosthetic femoral supracondylar fractures of total knee replacements-a new PHILOS-ophy

We report two cases where a proximal humeral locking plate was used for the fixation of an extremely distal, type Ⅲ peri-prosthetic femoral fractures in relation to a total knee replacement(TKR). In each case there was concern regarding the fixation that could be achieved using the available anatomic distal femoral plates due to the size and bone quality of distal fragment. The design of the Proximal Humeral Internal Locking System(PHILOS) allows nine 3.5-mm locking screws to be placed over a small area in multiple directions. This allowed a greater number of fixation points to be achieved in the distal fragment. Clinical and radiological short-term follow-up(6-12 mo) has been satisfactory in both cases with no complications. We suggest the use of this implant for extremely distal femoral fractures arising in relation to the femoral component of a TKR.

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.

Distal Radius Fracture: What Does the Patient Want?

Distal radius fractures are common and while historically most have been treated nonoperatively the frequency with which distal radius fractures are treated surgically is increasing. Criteria for considering surgical treatment are often based on radiographic appearance of the fracture. Less often discussed is patient preference: what do patients want. We investigated responses of a general population when presented with various treatment options following a hypothetical distal radius fracture. Many respondents chose nonoperative treatment even when told that surgery might result in a better outcome. This information can help during the shared decision-making process when discussing treatment options with a patient who presents with a distal radius fracture.

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.

Pulmonary thromboembolism after distal ulna and radius fractures surgery: A case report and a literature review

BACKGROUND Pulmonary thromboembolism(PTE)is a serious postoperative complication that can occur after a fracture.Generally,PTE is caused by the falling off of lower extremity deep vein thrombosis(LEDVT)after lower limb fracture surgery.LEDVT and PTE after upper extremity fracture surgery are very rare.PTE is one of the most common clinical causes of sudden death.Venous thromboembolism includes PTE and DVT.We experienced one case of LEDVT and PTE after distal ulna and radius fracture surgery.The purpose of our report is to raise awareness for orthopedic surgeons that PTE can occur after distal ulna and radius fracture surgery,and patients with high risk factors should be considered for prevention and treatment of thrombosis in a timely manner.CASE SUMMARY We report a 51-year-old Chinese male who had severe fractures of the left distal ulna,radius and little finger after a motorcycle accident.The patient underwent external fixation,open reduction and internal fixation.On the third post-operative day,computed tomographic pulmonary angiography showed PTE.Doppler ultrasonography showed thrombus formation in the bilateral posterior tibial veins.After a period of anticoagulation therapy,on the 25th d after the PTE,computed tomographic pulmonary angiography showed that thrombus in both sides of the pulmonary artery disappeared.Furthermore,about 4 mo after the PTE,thrombosis in the deep veins of the lower limbs disappeared.About 1 year after the surgery,X-rays showed good fracture healing,and the function of the wrist joint recovered well.CONCLUSION Though rare,PTE can occur after distal ulna and radius fracture surgery and patients with high risk factors should be considered for prevention and treatment of thrombosis in a timely manner.

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.

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.

Effect of fixing distal radius fracture with volar locking palmar plates while preserving pronator quadratus

Background L-shaped incision of pronator quadratus （PQ） muscle along its radial and distal borders was always taken for distal radius fractures reduction and internal fixation.Repair of the PQ muscle was always recommended at the end of operation for some instructive reasons.But repair of PQ is not satisfied because of poor quality of muscle and fascial tissues which may cause pain or impede forearm pronation and supination for post-operative scarring around PQ.Inserting the locking palmar plate to pass under the pronator quadratus muscle and the locking screws are inserted through miniincisions in pronator quadratus in some patients with distal radius fractures is a reasonable technique which can preserve the pronator quadratus.The purpose of this study was to evaluate and compare the clinical effects after volar plating of the distal radius fractures while preserving the pronator quadratus and pronator quadratus repair.Methods Between September 2010 and April 2012,65 patients （42 males and 23 females; aged 20-68 years and a mean age of 42.5 years） with distal radius fracture underwent open reduction and internal fixation using the volar locking palmar plates （Depuy or Smith companies）.The patients were classified as 23A-2 through 23C-3 according to the Orthopaedic Trauma Association （OTA） classifications.All surgeries were completed by the same trained team.The volar locking palmar plates of distal radius performed with preserving pronator quadratus group involved 30 patients including 19 males and 11 females and performed with pronator quadratus repair group involved 35 patients including 23 males and 12 females.We compared the two groups for wrist pain,forearm range of motion,grip strength,pedoperative complications and wrist functional recovery score.Results The minimum follow-up for the whole cohort was one year.The differences between the two groups were significant with regard to wrist pain,forearm range of motion,grip strength and wrist function at 1,2,and 6 weeks postoperatively,but insignificant at 6 and 12 months postoperatively.No significant differences were found in the pedoperative complications and radiographs postoperatively.Conclusions Preservation of the pronator quadratus muscle is a satisfactory method for the treatment of majority of the fractures of the distal radius with volar locking palmar plates,as this technique can yield better early wrist function and shorten the rehabilitation.
