The incidence of periprosthetic fractures has been reported to be between 1 and 20.9% and appears to be on the rise. Fractures that occur around the femoral stem, particularly when the stem is loose or there is a loss of bone stock pose a technical challenge. These are rare injuries and there is considerable debate regarding their optimal treatment. Reconstruction with large segment endoprosthetic replacement is an acceptable solution for elderly patients who have limited functional demands and where the prosthesis is expected to outlive the patient. The younger patient poses a much greater challenge, the bone must be reconstituted and the femoral canal geometry must sufficiently restored to allow the stable insertion of a prosthesis. There are very few techniques that exist in this scenario. One such technique is impaction bone grafting and revision to a long smooth tapered cemented stem. This allows the restoration of bone stock and the stable insertion of a prosthesis. The aim of this article is to discuss the theory behind impaction bone grafting, the technical aspects and challenges of this technique, including fracture reduction methods, and to appraise all the literature available on impaction bone grafting for periprosthetic fractures. 相似文献

Periprosthetic femoral fractures with severe bone loss are challenging to treat. There are various treatment options, depending on the severity of the bone loss, age and activity of the patient and experience of the surgeon. This review focuses on the treatment of these Vancouver type B3 fractures with long-stem implants, proximal femoral replacements, allograft-prosthesis composites and cortical strut grafting. 相似文献

Classification of femoral periprosthetic fractures 总被引:2,自引:2,他引:0
Classification systems for fractures of the femur with a prosthetic hip in situ are diverse and complex. Most of them are based on the site of the fracture, which is not the most important differentiating factor in treatment planning. The Coventry classification system groups the periprosthetic fractures into 'happy hips' and 'unhappy hips' based on whether or not the stem is loose. In 'happy' hips, treatment only needs to address the fracture itself, unless the fixation has been compromised by the fracture. In the 'unhappy hips', revision of the prosthesis is recommended. 相似文献

Osteopetrosis is an inherited disorder characterized by increased bone density and brittle bone quality. Degenerative changes often occur after the age of 40 in patients with osteopetrosis. Operative intervention is the primary treatment option if the clinical manifestation of secondary osteoarthritis is severe. A 44-year-old male suffering autosomal dominant osteopetrosis and progressive unilateral hip osteoarthritis required a total hip arthroplasty. However, there were several technical challenges associated with this procedure including creating a femoral medullary canal and developing a Vancouver type B2 periprosthetic femoral fracture postoperatively. To afford some experience for the management of similar cases, we here present our technical solutions to these problems. 相似文献

Background:
It is conventionally considered that bone grafting is mandatory for Vancouver B3 periprosthetic femoral fractures (PFF) although few clinical studies have challenged the concept previously. The aim of the current study was to investigate the radiographic and functional results of Vancouver B3 PFF treated by revision total hip or hemiarthroplasty (HA) in combination with appropriate internal fixation without bone grafting.Materials and Methods:
12 patients with Vancouver B3 PFF were treated by revision THA/HA without bone grafting between March 2004 and May 2008. There were nine females and three males, with an average age of 76 years. PFFs were following primary THA/HA in nine patients and following revision THA/HA in three. Postoperative followup was 5.5 years on average (range, 3.5-6.5 years). At the final followup, radiographic results were evaluated with Beals and Tower''s criteria and functional outcomes were evaluated using the Merle d’Aubigné scoring system.Results:
All fractures healed within an average of 20 weeks (range, 12-28 weeks). There was no significant deformity and shortening of the affected limb and the implant was stable. The average Merle d’Aubigné score was 15.8. Walking ability was regained in 10 patients without additional assistance, while 2 patients had to use crutches. There were 2 patients with numbness of lateral thigh, possibly due to injury to the lateral femoral cutaneous nerve. There were no implant failures, dislocation and refractures.Conclusions:
Revision THA/HA in combination with appropriate internal fixation without bone grafting is a good option for treatment of Vancouver B3 periprosthetic femoral fractures in the elderly. 相似文献17.
Introduction
Total knee arthroplasty is a common orthopaedic procedure in the UK; consequently, revision surgery and periprosthetic fractures are increasing in incidence. Strategies for management of these cases include non-operative strategies, internal plate fixation and revision of the distal femoral component. One under-reported practice is to perform distal femoral replacement in cases with poor distal femoral bone stock.Materials and methods
The department's electronic database was searched for all patients undergoing revision of total knee arthroplasty. From these, all patients having distal femoral replacement for periprosthetic fracture around the distal femoral component using the Stryker Global Modular Replacement System (GMRS) implant were filtered. A retrospective analysis of the patient notes was performed to examine the patient demographics, surgical factors and postoperative complications. Postoperative scores were performed for these patients.Results
From 2005 onwards, 11 patients (mean age 81 years, range 61–90 years) had their implants revised with a distal femoral replacement for periprosthetic fracture with associated poor bone stock. Follow up was for a mean of 33 months (range 4–72 months). One of these patients died of causes unrelated to their operation. Of the rest, all implants survived without the need of re-operation. The mean postoperative Oxford Knee Score for these patients was 22.5 (range 5–34).Conclusions
Distal femoral replacement for patients with fracture around a total knee arthroplasty has been performed in our department with few complications and acceptable functional outcomes. It is a technically challenging operation and it should be a salvage procedure reserved for patients with poor bone stock and low demands where other methods of fixation are not suitable.Level of evidence

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. 相似文献

Grafting for periprosthetic femoral fractures: strut, impaction or femoral replacement 总被引:4,自引:0,他引:4
Peri-prosthetic fractures are technically demanding to treat, as they require the skills of revision arthroplasty as well as those of trauma surgery. [Lindahl H, Malchau H, Herberts P, Garellick G. Periprosthetic femoral fractures classification and demographics of 1049 periprosthetic femoral fractures from the Swedish National Hip Arthroplasty Register. J Arthroplasty 2005;20:857-65.] reporting on 1049 periprosthetic femoral fractures found that the annual incidence varied between 0.045% and 0.13% for all THAs performed in Sweden and that the accumulated incidence for the primary hip arthroplasties was 0.4% while for the revision arthroplasties was 2.1% [Lindahl H, Malchau H, Herberts P, Garellick G. Periprosthetic femoral fractures classification and demographics of 1049 periprosthetic femoral fractures from the Swedish National Hip Arthroplasty Register. J Arthroplasty 2005;20:857-65.]. The elderly population is particularly vulnerable to low energy periprosthetic fractures attributed to osteopenia or osteoporosis leaving limited reconstruction options to the hip revision surgeon. Bone grafting in the form of autograft has well recognized limitations and allograft represents the gold standard of bone augmentation in the majority of the cases. Allograft can be used as morselised in the form of impaction grafting, reconstructing the bone from within out, or in the form of structural allograft. In the latter case, strut onlay plates or whole proximal femoral allografts can be used to augment the deficient bone or to totally replace it respectively. Immune reaction and disease transmission along with delayed revascularization of the cortical allograft can cause failure of the construct in the long term; however, the results to date from their use are promising. We here present an overview of the literature on the use of available bone grafts in the treatment of periprosthetic femoral fractures. 相似文献

Introduction Revision of cemented hip arthroplasty after periprosthetic fractures of the femur is a demanding procedure. Many different
technical devices have been developed for this purpose. This paper presents a new surgical technique of cement removal avoiding
excessive exposure of the fracture site.
Materials and methods In six patients with periprosthetic fractures of the femur following hip arthroplasty (Johansson Type II and III) cement removal
was performed by means of advancing a retrograde nail through the intercondylar notch of the knee.
Results In all cases the cement was removed completely. Intraoperative complications or significant knee problems were not observed.
Conclusion The intracondylar approach provides a simple, rapid and less invasive technique for cement removal in revision hip arthroplasty. 相似文献
