Limited intercarpal fusion as a salvage procedure for advanced Kienbock disease

Background

With progressive lunate collapse, salvage procedures in advanced Kienbock disease attempt to provide pain relief and maintain motion. Scaphocapitate arthrodesis may provide a durable option with comparable outcomes to proximal row carpectomy in the well-selected patient.

Methods

We performed a retrospective chart review of all consecutive patients with Lichtman stage IIIA or IIIB Kienbock’s disease who underwent either scaphocapitate or scaphotrapeziotrapezoid-capitate arthrodesis from January 2004 to December 2013.

Results

Twelve patients were included with a mean age of 41.6 years. Ten patients underwent scaphocapitate arthrodesis, while two patients underwent scaphotrapezio-trapezoid-capitate arthrodesis with an average clinical follow-up of 13.1 months. All patients achieved fusion. The average postoperative flexion-extension arc was 53° (range 20–110°). The average ulnar deviation was 9° (range 5–15°), and the average radial deviation was 13° (range 5–25°). Postoperative pain scores were significantly improved, having changed from an average of 6.6 preoperatively to 2.8 on a 10-point scale (W = 18, P < 0.05).

Conclusions

Despite a mean flexion-extension arc that is reduced from that of a normal individual, the postoperative range of motion following a midcarpal arthrodesis was not significantly different than that reported in a recent systematic review of proximal row carpectomy (73.5° compared with 53°, respectively) (P = 0.05). Additionally, given the significant postoperative reduction in associated pain symptoms at the time of follow-up, scaphocapitate arthrodesis should be considered as a treatment option for wrist salvage in the patient with advanced Kienbock’s disease.     

股骨粗隆间骨折PFNA内固定失效的危险因素分析

目的分析导致股骨粗隆间骨折PFNA内固定失效的危险因素。方法回顾性分析自2010-01—2013-10诊治并获得完整随访的股骨粗隆间骨折157例,按照内固定失效与否分为A(内固定失效组)、B(内固定成功组)2组。观察指标:外侧壁厚度、外侧壁分型、尖顶距(TAD)、螺旋刀片头所在区域、正侧位X线片上远近端皮质对位差。结果 157例获得平均14.6(12~18)个月随访,24例(15.3%)出现内固定失效。11例髋内翻,2例退钉,2例内固定切割,18例复位丢失,4例股骨颈短缩。A组外侧壁厚度小于B组,差异有统计学意义(P0.05)。A组TAD30 mm者比例明显高于B组,差异有统计学意义(χ2=11.386,P=0.003)。2组螺旋刀片头所在区域及正侧位X线片上远近端皮质对位差比较差异无统计学意义(P0.05)。A组Ⅱ、Ⅲ型外侧壁骨折占87.5%,而B组仅为36.1%,差异有统计学意义(χ2=32.305,P=0.001)。结论PFNA内固定治疗股骨粗隆间骨折时,股骨近端外侧壁的厚度过小,Ⅱ、Ⅲ型不稳定外侧壁骨折,以及TAD30 mm可能是发生内固定失效的危险因素。     

股骨近端锁定钢板与Gamma 3型髓内钉固定不稳定股骨粗隆间骨折的生物力学研究

目的比较股骨近端锁定钢板与Gamma 3型髓内钉在固定不稳定股骨粗隆间骨折中的生物力学特性,为临床选择内固定方式提供理论依据。方法选取5对防腐股骨标本,每对标本配对随机分为A组和B组,所有股骨标本制成31-A2.2型骨折模型,A组使用Gamma 3型髓内钉固定,B组使用股骨近端锁定钢板固定,在力学测试机上进行轴向压缩、扭转、破坏试验。结果在1 200 N载荷时,A组轴向刚度为(306.52±11.32)N/mm,B组为(258.38±14.63)N/mm,A组的轴向刚度较B组高18.6%,差异有统计学意义(t=17.74,P=0.03)。A、B组在扭转角为0.5°、1.0°、1.5°、2.0°、2.5°时的扭矩值差异均无统计学意义(P0.05)。A组扭转刚度为(1.35±0.06)N·mm/deg,B组为(1.48±0.09)N·mm/deg,2组差异无统计学意义(t=-5.00,P=0.13)。A组最大屈服载荷为(3 101.33±174.83)N,B组最大屈服载荷为(2 396.68±142.07)N,A组最大屈服载荷值较B组高29.4%,差异有统计学意义(t=48.52,P0.001)。结论股骨近端锁定钢板在内固定治疗以31-A2.2型骨折为例的不稳定股骨粗隆间骨折时,其轴向负重力学性能不如Gamma 3型髓内钉,不宜作为首选内固定。

Cemented hemiarthroplasty or hip replacement for intracapsular neck of femur fracture? A comparison of 7732 matched patients using national data

Background

The treatment of choice for intracapsular neck of femur (NOF) fractures in younger, more active patients remains unknown. Some surgeons advocate total hip replacement (THR).

Aim

This study aimed to compare complications following THR and hemiarthroplasty using the Hospital Episode Statistics (HES) database in England.

Method

Dislocation and revision rates were extracted for all patients with NOF fracture who underwent either cemented hemiarthroplasty or cemented THR between January 2005 and December 2008. To make a ‘like for like’ comparison all 3866 THR patients were matched to 3866 hemiarthroplasty patients (from a total of 41,343) in terms of age, sex and Charlson score.

Results and conclusion

Eighteen-month dislocation was significantly higher in the THR group (2.4% vs. 0.5%, odds ratio (OR) 3.90 (2.99–5.05), p < 0.001). This difference was sustained at the 4-year stage (2.9% vs. 0.9%, OR 3.18 (1.58–6.94), p = 0.001) in a subset of patients with longer follow-up. There was no significant difference in revision rate up to 4 years (1.8% vs. 2.1%, OR 0.85 (0.46–1.55), p = 0.666). In this national analysis of matched patients short- and medium-term dislocation rates following THR were significantly higher than following cemented hemiarthroplasty, without any difference in revision rates at 4 years. The low risk of dislocation may be acceptable in order to experience the apparent functional benefits of THR.     

利塞膦酸钠对非骨水泥型全髓关节置换术后早期股骨假体周围骨密度的影响

目的 探讨利塞膦酸钠对非骨水泥型全髋关节置换术后早期股骨假体周围骨密度的影响及治疗作用,以其为临床提供防止假体周围骨丢失和松动的预防措施和处理方法.方法 2011年3月～2012年5月于本院行非骨水泥型人工全髋关节置换术中符合纳入标准的患者共26例随机分成利塞膦酸钠组与对照组;试验组术后每日口服利塞膦酸钠5 mg+钙剂600 mg,而对照组仅服用钙剂600 mg;分别于术后1周、3、6个月测定股骨近端各感兴趣区(ROI)的骨密度.结果 获得完整病例24例,术后3、6个月各区骨密度均呈持续下降趋势,和对照组相比,术后3个月利塞膦酸钠组股骨假体(ROI1、ROI7)的差异有统计学意义(P＜0.01),其余各测量区骨密度2组相比差异无统计学意义(P＞0.05).与对照组相比,术后6个月利塞膦酸钠组股骨假体(ROI1、ROI7)的差异有统计学意义(P＜0.01),其余各测量区骨密度2组相比差异无统计学意义(P＞0.05).结论 利塞膦酸钠能够有效的减少非骨水泥型全髋关节置换术后假体周围的骨丢失,从而减缓假体松动,延长假体使用寿命.
