Plain films are not accurate in planning internal fixation in vancouver type B1 periprosthetic femoral fractures and in distinguishing between subtypes B1 And B2

BackgroundWhile few studies analysed the diagnostic validity of preoperative radiographs in distinguishing between Vancouver type B1 and B2 periprosthetic femoral fractures (PFFs), no investigation has been conducted to assess the degree of diagnostic validity of preoperative radiographs in identifying the fracture course and planning the most appropriate treatment. We analysed the diagnostic validity of radiographs in detecting the fracture course and stem stability in Vancouver type B PFFs.MethodsVancouver type B PFFs with different fracture courses were randomly performed in 36 dried cadaveric femurs in which a femoral broach had previously been implanted. Radiographic images, taken in the coronal and sagittal views, were analysed by 5 orthopaedic surgeons and 2 radiologists who were asked to reproduce the fracture course and to evaluate stem stability. A scoring system was used to determine the injured femoral cortex correctly identified by the examiners.ResultsThe identification of the fracture course was scored as poor in 52.4% and 56.%, fair in 23% and 23.4% and good in 24.6% and 19.8%, The identification of the fracture course in the coronal and axial vies radiographs was scored in coronal and axial view radiographs respectively. There was no significant difference in the average score obtained by senior and young examiners. In the coronal plane, the fracture course was poorly identified by all examiners in 11 (30.5%) femurs and by 5 or more examiners in 17 (47%). The fracture course was correctly identified by 5 or more examiners in 8 femurs (22%). A vertical fracture involving an emidiaphysis was found in 8 of the 11 femurs in which the PFF was poorly diagnosed by all examiners. Stem instability was correctly diagnosed in 45% of cases.ConclusionsIn type B PFFs preoperative radiographs show a reduced diagnostic validity in identifying the fracture course and, hence, in planning a correct treatment. Potentially unstable vertical fractures involving an emidiaphysis are likely to be poorly diagnosed since most of the fracture course is hidden by the femoral stem. In cementless stems the diagnostic validity of radiographs in diagnosing between Vancouver type B1 and B2 seems to be lower than that reported for cemented stems.

Anterior tibiofibular ligament avulsion fracture in weber type B lateral malleolar fracture

BACKGROUND: The purpose of this study was to determine the incidence, relationship with the ankle diastasis, and effect of treatment of the anterior tibiofibular ligament avulsion fracture (Wagstaffe fracture) combined with the Weber type B lateral malleolar fracture. METHODS: This study reviewed 94 cases of ankle fractures treated with operative methods. RESULTS: There were 52 cases of Weber type B lateral malleolar fractures and 13 cases of Wagstaffe fractures combined with them (25%). Ankle diastases were diagnosed in 20 cases (38.5%) in all Weber type B fractures and 11 (84.6%) of the 13 Wagstaffe fractures. CONCLUSION: The Wagstaffe fracture can be a good diagnostic clue of ankle diastasis in Weber type B lateral malleolar fracture. The accurate reduction and fixation of the avulsed fragment is important for restoration of the stable distal tibiofibular joint and to prevent the chronic ankle joint pain caused by impingement of the avulsed fragment.     

Extensively porous-coated stems for femoral revision: reliable choice for stem revision in Paprosky femoral type III defects

Between January 1999 and August 2008, ninety-six femoral revisions were performed with extensively porous-coated stems in Paprosky type III femoral defects (89 type IIIA and 7 type IIIB defects). Seven type IIIB defects with a mean canal of 16.5 mm were observed; 6 defects achieved stable bone ingrowth and 1 achieved stable fibrous condition. Average postoperative Harris Hip Score was 92.3±8 (range, 77-100), and all scores improved postoperatively. At a mean follow-up of 65.7 months, 92 stems achieved bone ingrowth, and 1 stem (type IIIB) achieved a stable fibrous condition. Three patients died from causes unrelated to the surgery during follow-up. The most frequent diagnosis for revision of the femoral component was loosening of the cementless stem (53 patients; 55.2%), followed by status after a Girdlestone procedure (21 patients; 21.8%), after total hip arthroplasty with acetabular wear (10 patients; 10.4%), loosening of the cemented stem (7 patients; 7.3%), and periprosthetic fracture (5 patients; 5.2%). The authors performed 65 total hip arthroplasty revisions, 23 femoral component revisions, and 8 revisions of femoral components with cemented liners in patients with well-fixed acetabular shells. Extensively porous-coated stems in femoral revision for Paprosky type III femoral defects provided good mid-term durability.

Profunda femoris artery pseudoaneurysm following revision for femoral shaft fracture nonunion

Femoral artery pseudoaneurysms (FAPs) have been described following internal fixation of intertrocantheric, subtrocantheric and intracapsular femoral neck fractures as well as core decompression of the femoral head. The diagnosis of FAP is usually delayed because of non-specific clinical features like pain, haematoma, swelling, occasional fever and unexplained anaemia. Because of the insidious onset and of the possible delayed presentation of pseudoaneurysms, orthopaedic and trauma surgeons should be aware of this complication. We report a case of Profunda Femoris arterial branch pseudoaneurysm, diagnosed in a 40-year-old male 4 wk after revision with Kuntscher intramedullary nail of a femoral shaft nonunion. The diagnosis was achieved by computed tomography angiography and the lesion was effectively managed by endovascular repair. The specific literature and suggestions for treatment are discussed in the paper.     

Locking compression plate versus revision-prosthesis for Vancouver type B2 periprosthetic femoral fractures after total hip arthroplasty

IntroductionRevision arthroplasty is currently the recommended treatment for periprosthetic femoral fractures after primary total hip arthroplasty (THA) and stem loosening (Vancouver B2). However, open reduction and internal fixation (ORIF) utilizing locking compression plate (LCP) might be an effective treatment with a reduced surgical time and less complex procedure in a typically elderly patient collective with multiple comorbidities. The purpose of this study was to compare the functional and radiographic outcomes in two cohorts with Vancouver B2 periprosthetic femoral fractures after primary THA, treated either by ORIF with LCP fixation, or by revision arthroplasty utilizing a non-cemented long femoral stem.Materials and Methods36 patients with Vancouver B2 periprosthetic femoral fractures following THA, who had been treated between 2000 and 2014, were reviewed. Eight fractures were treated with LCP fixation, fourteen fractures with the first-generation revision prosthesis (Helios^®), and fourteen fractures with the second-generation revision prosthesis (Hyperion™). The patients were assessed clinically with the Parker mobility score and radiographically.ResultsA total of ten males and 26 females formed the basis of this report with an average age of 81years (range, 64 to 96 years). All fractures treated with LCP fixation alone healed uneventfully and there were no signs of secondary stem migration, malalignement or plate breakage. The average surgical time was shorter in the ORIF cohort; however, the results were not statistically significant. The postoperative Parker mobility score at latest follow-up showed no difference between the groups.ConclusionsAccording to the results of the current study, we conclude that the use of LCP fixation can be a sufficient option for the treatment of Vancouver B2 periprosthetic femoral fractures correspondingly with femoral stem loosening.
