Patients with Parkinson's disease and poliomyelitis can have a femoral neck fracture; yet, the optimal methods of treatment for these hips remains controversial. Many constrained or semi-constrained prostheses, using constrained liners (CLs) with a locking mechanism to capture the femoral head, were used to treat femoral neck fractures in patients with neurological disorders. We retrospectively studied a group of patients with Parkinson's disease and poliomyelitis who sustained femoral neck fractures and were treated by total hip arthroplasty using an L-MoM prosthesis.
We retrospectively reviewed 12 hips in 12 patients who underwent large-diameter metal-on-metal (L-MoM) total hip replacement between May 2007 and October 2009. Eight of the 12 patients (8 hips; 66.7%) had Parkinson's disease and 4 patients (4 hips; 33.3%) were affected with poliomyelitis.
The followup time was 5.2 years (range 3.6-6.0 years). At the latest followup, all the patients showed satisfactory clinical and radiographic results, with pain relief. No complications, such as dislocation or aseptic loosening occurred.
We believe the use of L-MoM can diminish the rate of instability or dislocation, after operation. The L-MoM is an option for patients with Parkinson's disease and poliomyelitis with femoral neck fracture.
帕金森病患者和小儿麻痹症患者可能会发生股骨颈骨折；然而，针对这些髋关节的最佳治疗方法仍存在争议。许多受限或半受限假体，使用带有锁定机制以固定股骨头的受限衬垫（CLs），被用于治疗神经疾病患者的股骨颈骨折。我们回顾性研究了一组患有帕金森病和小儿麻痹症且发生股骨颈骨折并接受L - MoM假体全髋关节置换术治疗的患者。
我们回顾性分析了2007年5月至2009年10月期间接受大直径金属对金属（L - MoM）全髋关节置换术的12例患者的12个髋关节。12例患者中有8例（8个髋关节；66.7%）患有帕金森病，4例患者（4个髋关节；33.3%）患有小儿麻痹症。
随访时间为5.2年（范围3.6 - 6.0年）。在最近一次随访时，所有患者的临床和影像学结果均令人满意，疼痛缓解。未发生脱位或无菌性松动等并发症。
我们认为使用L - MoM可降低术后不稳定或脱位的发生率。L - MoM是患有帕金森病和小儿麻痹症且发生股骨颈骨折患者的一种选择。
