Minimally invasive plate osteosynthesis with locking compression plate in patients with Vancouver type B1 periprosthetic femoral fractures

BackgroundPeriprosthetic femoral fractures (PFF) following total hip arthroplasty (THA) remain one of the most challenging complications to address. Although the principal treatment modalities for Vancouver type B1 fractures are open reduction and internal fixation (ORIF), surgeons have not yet reached a consensus on the optimal method for reduction and fixation. We therefore investigated whether minimally invasive plate osteosynthesis (MIPO) using locking compression plate (LCP) would lead to favorable outcomes for patients with Vancouver type B1 PFFs. In addition, we also compared the outcomes of patients treated with MIPO to those treated with ORIF.MethodWe retrospectively evaluated the clinical and radiographic outcomes of a series of 21 Vancouver type B1 PFFs treated with MIPO and LCP between February 2011 and February 2017. The mean duration of follow-up was 33.8 months. We also compared outcomes of these patients to those of patients with 19 Vancouver type B1 fractures treated with ORIF between April 2006 and December 2011.ResultsFracture healing without complications was achieved in 20 (95.2%) out of 21 cases in the MIPO group and in 14 (87.5%) out of 16 cases in the ORIF group. There was one case of fixation failure with stem subsidence in the MIPO group. In the ORIF group, there were 2 nonunion with metal failure. Operation time was significantly shorter and intraoperative blood loss was significantly less in the MIPO group compared to the ORIF group. However, there were no significant differences in frequency of transfusion, time-to-union, walking abilities, modified Harris hip score, or complications.ConclusionThe radiological and clinical outcomes of MIPO using LCP in patients with Vancouver type B1 PFFs were shown not to be inferior to ORIF and resulted in fewer intraoperative complications than ORIF. If care is taken regarding the stability of femoral implant and optimal surgical techniques, MIPO may be a recommended option in the treatment of Vancouver type B1 periprosthetic fracture.     

关于温哥华C型股骨假体周围骨折采用不同长度锁定钢板固定的生物力学研究

目的通过比较四种不同长度的锁定钢板在治疗温哥华C型股骨假体周围骨折的生物力学实验中的表现，来分析锁定钢板相对于股骨假体柄远端的位置与产生的刚度和应力集中情况的关系。 方法选取10对成人新鲜股骨标本，随机均分为四组，制作温哥华C型股骨假体周围骨折模型，以四种不同长度的锁定钢板固定：A组，钢板最近端双皮质锁定螺钉距离假体尖端1个股骨直径；B组，钢板最近端双皮质锁定螺钉与假体尖端平齐；C组，钢板最近端单皮质锁钉与假体尖端重叠1个股骨直径；D组，钢板最近端单皮质锁钉与假体尖端重叠2个股骨直径。分别进行轴向压载实验、扭转实验、内外四点侧弯实验及前后四点侧弯实验，记录各组数据并进行统计学分析；最后进行循环负载实验，记录骨折情况。 结果各组在各实验中表现出的刚度值有显著差异，D组刚度值最大（P<0.05）；在循环负载实验中，D组骨折线分布于股骨假体尖端、近端锁钉以及钢板远端附近，A、C组的骨折线集中在近端锁钉与股骨假体尖端之间，B组骨折线集中在股骨假体尖端与钢板顶端的线性区域内，结果显示D组应力集中程度比A、B、C三组低（P<0.05）。 结论在使用锁定钢板治疗温哥华C型股骨假体周围骨折时，随着钢板长度增加，内固定稳定性提高；锁定钢板与股骨假体柄尖端重叠固定不会增加应力集中，反而随着钢板与股骨假体重叠区域增加，应力显著分散。     

An international,cross-sectional survey of the management of Vancouver type B1 periprosthetic femoral fractures around total hip arthroplasties

IntroductionThe incidence of periprosthetic femoral fractures around total hip arthroplasties is increasing. Fractures around a stable implant stem (Vancouver type B1) are among the most common of these fractures. Various fixation strategies for Vancouver type B1 periprosthetic fractures have been reported in the literature; however, little high-level evidence exists. This study was designed to determine the current management strategies and opinions among orthopaedic surgeons treating Vancouver type B1 periprosthetic femoral fractures, and to evaluate the need for a large prospective randomized controlled trial for the management of these injuries.MethodsOrthopaedic surgeon members of the Orthopaedic Trauma Association (OTA), the Canadian Orthopaedic Association (COA), and the Hip Society were invited to participate in a 51-item web-based survey surrounding the management of periprosthetic femoral fractures around total hip replacements, as well as the perceived need for future research in this area. Responses were summarized using proportions, and further stratified by practice type, case volume, surgeon age, and fellowship training.ResultsFor Vancouver type B1 fractures, open reduction and internal fixation (ORIF) with locked plating was favoured slightly over ORIF with cable plating ± cortical strut allograft (51.1% versus 45.5%). When compared to cable plating with cortical strut allograft, respondents believed that isolated locked plating resulted in lower nonunion and reoperation rates, but similar infection and malunion rates. Subgroup analyses revealed that practice type, surgeon age, case volume, and fellowship training influenced surgeons’ management of periprosthetic femoral fractures and beliefs regarding complications. There is high demand for a large prospective randomized controlled trial for Vancouver type B1 fracture fixation.ConclusionsConsensus surrounding the management of Vancouver type B1 periprosthetic femoral fractures is lacking, and there is a perceived need among orthopaedic surgeons for a large prospective randomized controlled trial in order to define the optimal management of these injuries.     

Locking plate osteosynthesis for Vancouver Type B1 and Type C periprosthetic fractures of femur: a report on 12 patients

Many methods have been described to stabilise periprosthetic fractures around a total hip arthroplasty. Locking plate fixation offers increased angular stability and, theoretically, better fixation in osteoporotic bone. This study presents our results with the use of locking plate fixation for Vancouver Type B1 and Type C periprosthetic fractures following total hip arthroplasty (THA). Twelve patients underwent fixation of periprosthetic fractures with either a locking compression plate (LCP) or a distal femur less invasive stabilisation system (LISS). There were six Type B1 and six Type C fractures. One patient died soon after surgery. The mean follow-up was 13.9 months (range 12-18 months). The fracture healed in 10 of the remaining 11 patients with a median time to union of 4.8 months. There was one implant failure prior to fracture healing and one implant failure after fracture healing. Both were attributed to technical errors. Seven patients returned to their previous level of mobility. Two patients required the use of one walking stick after fracture healing, but had been able to walk unaided before their fall. One patient required two sticks, after previously requiring only a single stick. There were no infections. Our experience encourages us that locking plates have a role to play in managing periprosthetic fractures around a stable femoral stem, especially in patients with poor soft tissue and osteoporosis.     

Early experience with the use of trochanteric reattachment plate for the treatment of Vancouver type B 1 periprosthetic hip fractures

ObjectiveThe purpose of our study is to study the usefulness of trochanteric reattachment plate in the management Vancouver type B 1 periprosthetic femur fractures.MethodsWe describe a case series of 15 (12 F: 3 M) Vancouver type B 1 fracture fixed with trochanteric reattachment plate with 3 years follow up. Patients with Vancouver A, B2, B3 and C fractures were excluded in the study. Clinical and radiological assessment of patients was done at 1, 3, 6, 9, 12, 24 and 36 months. The parameters evaluated were fracture union, Harris hip score and post-operative complications if any.ResultsPatients mean age was 74 years (range 58–84). Eleven patients were operated with cemented hemiarthroplasty while 4 patients had total hip arthroplasty done before. Operation time mean was 137.2 min and mean surgical blood loss was 522.66 ml. All the patients achieved radiological union of the fracture at mean of 14.13 weeks. Mean Harris hip Score was 82 at 36 months follow up. 13 out of 15 hips (86.67%) showed good clinical results and 2 patients (13.33%) showed fair result. All the patients returned to their pre injury activities of daily living.ConclusionOperative fixation of Vancouver type B 1 periprosthetic fractures is a challenge for an orthopedic surgeon. Open reduction and internal fixation of these fractures using of trochanteric reattachment plate incorporating screws and cerclage wires through the plate provides good outcome in these patients. Use of this plate offers the surgeon stability against shearing as well as rotational forces.     

Isolated locked compression plating for Vancouver Type B1 periprosthetic femoral fractures

Objective

Report treatment results of periprosthetic femoral fractures adjacent or at the tip of a stable femoral stem (Vancouver Type B1) using a locked compression plate as the sole method of fracture stabilisation.

Design

Retrospective case series.

Setting

Academic Level I Trauma Centre.

Patients

Patients operatively treated at our institution with locked compression plating for Vancouver Type B1 periprosthetic fractures between 2002 and 2006 with at least 12 weeks of clinical follow-up were included. Patient demographics, hip arthroplasty implant characteristics, and AO/OTA fracture type were recorded.

Intervention

Open reduction internal fixation using a locked-plate spanning a majority of the femur through a lateral soft-tissue sparing approach. No cortical onlay allografts or cerclage devices (wires or cables) were used.

Main outcome measurements

Clinical union was defined at a minimum of 12 weeks as ability to walk, with or without the use of a walking aide, without pain at or around the fracture site. Radiographic union was defined by bridging bone spanning two or more cortices on orthogonal radiographs of the femur.

Results

Ten subjects met the inclusion criteria and were followed for a mean of 27 weeks (range 14-97 weeks). All achieved fracture union at a mean of 17 weeks (range 12-27 weeks). There were no hardware failures or changes in fracture alignment from operative radiographs. There were no major complications that necessitated reoperation.

Conclusions

Open reduction internal fixation of Vancouver Type B1 periprosthetic femoral fractures using a lateral locked-plate that spans the full extent of the femur as the sole method of stabilisation is a successful treatment method that minimises soft-tissue dissection and provides adequate fixation strength to maintain fracture alignment to fracture union.
