Cementless hemiarthroplasty in hip fracture surgery has been associated with poorer outcomes and more pain than cemented hemiarthroplasty. The aim was to investigate clinical and radiographic outcomes for a cementless tapered titanium fully hydroyxapatite-coated (Corail® System) stem in this consecutive cohort of hip fracture patients. We retrospectively evaluated the results of 68 consecutive elderly patients with displaced intracapsular hip fractures, treated with this implant. Mean clinical follow-up was 4.3 years (2-6 years). One-year mortality was 24%. 95% of patients had no/occasional/mild mid-thigh pain, with moderate pain in 5%. 39% achieved independent or walking-stick mobility. 36 patients had follow-up radiography. Osseointegration was noted in 34, with a mixed bony/fibrous in-growth in 2. One patient had revision for subsidence of an undersized implant, with no conversions to total hip arthroplasty. The Corail® stem can be used effectively for the treatment of femoral neck fractures in the elderly.
在髋部骨折手术中，非骨水泥半髋关节置换术与骨水泥半髋关节置换术相比，疗效较差且疼痛更多。本研究旨在调查在这一连续队列的髋部骨折患者中，使用非骨水泥锥形钛全羟基磷灰石涂层（Corail®系统）假体柄的临床和影像学结果。我们回顾性评估了68例连续的老年囊内移位髋部骨折患者使用该植入物的治疗结果。平均临床随访时间为4.3年（2至6年）。1年死亡率为24%。95%的患者无/偶尔有/轻度大腿中部疼痛，5%有中度疼痛。39%的患者实现了独立行走或借助拐杖行走。36例患者进行了随访影像学检查。34例观察到骨整合，2例为骨/纤维混合长入。1例患者因植入物尺寸过小下沉而进行了翻修，无患者转为全髋关节置换术。Corail®假体柄可有效用于治疗老年股骨颈骨折。
