Gamma钉治疗股骨粗隆间骨折的研究进展

粗隆间骨折是老年人常见的一种骨折,如何治疗使之尽快恢复下肢功能、减少长期卧床并发症、避免2次手术非常重要。目前老年粗隆间骨折常用的经典治疗方法是动力髋螺钉(DHS)、滑动髋螺钉(SHS)、加压髋螺钉(CHS)等,由于是偏心性固定,对不稳定的粗隆下骨折固定稍差,髓内系统生物力学较好,包括髋部髓内钉(intramedullaryhipscrew ,IMHS)、Gamma钉和股骨近端钉(PFN)等。1　Gamma钉的生物力学Gamma钉力矩较短,抗弯应力强[1] ,髓内钉比DHS可减少约2 5 %～3 0 %的弯曲应力,减少内固定物折断[2 ] 。骨折不稳定时Gamma钉对股骨距的加压应力增…

Mid-term outcomes after intramedullary fixation of peritrochanteric femoral fractures using the new proximal femoral nail antirotation (PFNA)

Background

Controversy persists concerning the preferred treatment of peritrochanteric femoral fractures. The purpose of the present study was to evaluate the mid-term outcomes of the newly developed implants - proximal femoral nail antirotation (PFNA) for the stabilisation of this type of fracture.

Methods

Between April 2006 and March 2008, 169 patients with peritrochanteric femoral fractures were treated with PFNA. As many as 26 patients were excluded from the study. According to the Orthopaedic Trauma Association (OTA) classification system, the remaining 143 fractures were classified as 19 cases of AO/OTA 31A1 fractures, 83 cases of 31A2 fractures, 28 cases of 31A3 fractures and 13 cases of 31A combined with proximal 32 fracture or separate proximal 32 fracture. The mean age of these patients was 67 years (range, 20-93 years). The operative time, the overall fluoroscopy time, the duration of hospitalisation and the surgical complications were noted. Patients were followed up for a mean of 21 months (range, 12-36 months). Functional outcomes were assessed according to the Harris hip scoring system.

Results

Fifteen patients (10%) required open reduction. The mean duration of surgery (from the beginning of close reduction to wound closure) was 72 min with a range between 45 and 170 min. The mean fluoroscopy time was 164 s with a range between 92 and 396 s. The mean time of hospital stay was 15 days. Postoperative X-rays showed a good or acceptable reduction in 134 cases (94%), and an ideal implant position in 131 cases (92%). There were 12 (8%) postoperative complications. All patients except one healed their fractures without any implant-specific complication (bending, breaking of the implant, cut out of the PFNA blade, femoral head penetration of the blade or ipsilateral fractures of the femoral shaft at the tip of the implant). The average time to bone healing was 16 weeks (range, 12-25 weeks). At the time of the latest follow-up, 106 patients (74%) were restored to their preoperative mobility. The mean Harris hip score was 84 points (range, 46-100 points). A total of 106 patients (74%) had an excellent or good outcome. According to the patients and/or their caregivers, outcome was described as satisfactory in 120(84%) of the 143 patients, and 36(90%) of the 40 patients, who were more than 80 years old.

Conclusion

The results suggest that PFNA is a very effective and safe method in the treatment of different patterns of peritrochanteric femoral fractures. The fixation is adequate to maintain reduction over time even in osteoporotic bones.

The Gamma nail for peritrochanteric fractures.

The Gamma nail was designed to treat unstable intertrochanteric and subtrochanteric fractures. The device was developed after cadaver studies and has been used clinically since February 1985 in a total of 421 patients. The results in 123 patients treated by the third version of this design are reported. The Gamma nail transmits weight closer to the calcar than does the dynamic hip screw and it has greater mechanical strength. A semi-closed operative technique is used, with an average duration of operation of 35 minutes and little blood loss. Distal locking screws can be used to maintain rotational stability, and can be inserted without the use of an image intensifier. Results showed satisfactory fracture union with little loss of position, even in comminuted fractures. Operative complications were few, but included fractures of the base of the greater trochanter. The most important postoperative complication, seen in one case, was fracture of the shaft of the femur at the distal end of the nail, but this healed well after re-nailing.     

不稳定型转子周围骨折的临床治疗分析

目的比较不稳定型转子周围骨折采用亚太型Gamma钉(Gamma-AP钉)和动力髋螺钉(DHS)固定的手术疗效。方法68例不稳定型骨折患中，31例使用Gamma-AP钉固定，37例使用DHS固定，并对手术资料、术后并发症及髋关节功能进行临床随访分析。结果Gamma钉手术切口长度、术中出血量较DHS手术小，而且患可早期下床负重而不增加术后并发症发生率。结论Gamma钉手术创伤小，适用性强，是治疗不稳定型转子周围骨折的理想方法之一。     

Percutaneous treatment of peritrochanteric fractures using the Gamma nail

The goal of the current study was to analyze patients treated with the Gamma nail, and to describe techniques that prevent commonly reported complications. One hundred patients with closed peritrochanteric femur fractures were treated by one surgeon using the Gamma nail. Ninety patients met the minimum 6 month followup requirement. Eighty-eight of the 90 fractures (98%) healed after the index procedure. There were nine (10%) complications (nine patients) with four patients (4%) requiring surgical intervention. One patient required total hip arthroplasty because of nonunion, and one patient required cerclage wiring of a postoperative femoral fracture. The third patient had an infection develop which resolved after debridement and a course of antibiotics. The fourth patient complained of thigh pain, which resulted in hardware removal. In the five remaining patients with complications, one patient had multi-infarct dementia and the family refused additional treatment, two patients with intraoperative femur fractures did not require treatment and two patients with thigh pain did not require additional treatment. Surgical time averaged 53 minutes and blood loss averaged 104 cc. Percutaneous fixation using the Gamma nail is effective in treating patients with peritrochanteric fractures. Surgical time and blood loss were minimized, early weightbearing was initiated, and previously reported complications were decreased.     

Intramedullary Gamma nail fixation in the treatment of peritrochanteric fractures]

The paper presents the authors' own experience in the treatment of periotrochanteric fractures. A clinical survey from 1998 to 2001 was carried out on 26 patients aged 21-72. The number of women was 20 (77%) and of men 6 (23%). This paper is an preliminary report.     

骨水泥型人工股骨头置换和PFNA治疗高龄不稳定转子间骨折疗效观察

【】 目的：探讨骨水泥型人工股骨头置换和股骨近端防旋髓内钉(Proximal Femoral Nail Anti-rotation, PFNA)治疗高龄不稳定型股骨转子间骨折的临床疗效。方法:对我科2008-2013年采用骨水泥型人工股骨头置换术和PFNA固定术治疗的68例高龄不稳定型股骨转子间骨折患者进行回顾性研究,其中人工股骨头置换组32例,PFNA固定组36例。比较两组手术时间、术中出血量、术后引流量及关节功能评分等。结果：68例患者失访2例(均为PFNA组),4例死亡(两组各为2例)。其余72例随访时间平均20.8月(12-36个月)。人工股骨头置换组和PFNA组手术时间分别为(49．1±10．6)、(57．6±7．2)min,术中出血量平均分别为(204．2±36．1)、(98.2±32．3)mL,术后引流量平均分别为(110．5±26．3)、(58.7±15.7)mL,术后一月及末次随访关节功能Harris评分分别为股骨头置换组为(61.20±4.37)、(87.92±3.02)分,PFNA组(54.60±3.18)、(78.86±8.13)。股骨头置换组在手术时间和术后关节功能评分优于PFNA组(p＜0.05),而术中失血量和术后引流量多于PFNA组(p＜0.05)。结论：两种方法均可有效治疗高龄股骨转子间骨折,但是应根据患者骨折类型及身体情况进行评估,对于不稳定型股骨转子间骨折患者若骨折前可正常行走,术前评估可耐受较大手术者可选取骨水泥型人工股骨头置换术。对于不能耐受较大手术的不稳定型转子间骨折可采取PFNA固定术。     

Modified Ender nail in the treatment of unstable peritrochanteric fractures]

The distal migration of the nails has been described as the most common complication in the treatment of the unstable peritrochanteric fractures with Ender nailing. Because of his design and site of insertion Ender nails are backing out secondary to collapse and impaction of the fractures. Author presented a new modified Ender nails with special notches on its surface, which was used in 19 males and 3 females aged 37-86 (mean 56.9) with unstable peritrochanteric fractures. Three patient died before solid union was achieved. Among 19 patient with healed fractures, distal backing of the new nails was observed in one. In six patients distal migration of the nails was less than 1 cm. Roughening of the nail's surface reduce the risk of distal migration in the treatment of unstable peritrochanteric fractures by Ender method.
