PFNA与解剖型锁定钢板内固定治疗老年股骨粗隆间骨折的疗效比较

目的比较股骨近端防旋髓内钉(PFNA)与股骨近端解剖型锁定钢板内固定治疗老年股骨粗隆间骨折的临床疗效。方法回顾性分析自2010-01—2013-01诊治老年股骨粗隆间骨折61例,采用PFNA内固定31例,采用股骨近端解剖型锁定钢板内固定30例。比较2组切口长度、手术时间、术中失血量、术后完全负重时间、骨折愈合时间、颈干角丢失情况和术后1年髋关节功能Harris评分。结果与锁定钢板组相比,PFNA组切口长度、手术时间较短,术中失血量较少,差异有统计学意义(P0.05)。术后61例均获随访10~18个月,平均12.6个月,X线片均显示骨折愈合;PFNA组术后完全负重时间、骨折愈合时间较锁定钢板组短,差异有统计学意义(P0.05);2组术后1年Harris评分及颈干角丢失差异无统计学意义(P0.05)。结论 PFNA和股骨近端解剖型锁定钢板内固定均是治疗老年股骨粗隆间骨折的有效手术方法,但PFNA内固定手术时间短、创伤小、固定牢靠、负重时间早,在治疗不稳定老年股骨粗隆间骨折时更有优势。

Total Femur Replacement in Sarcoma of the Distal end of the Femur

Five patients with sarcoma of the distal end of the femur were treated by a total resection of the femur and its replacement by an endoprosthesis. This was to preserve the body image, prevent mutilation and permit independent ambulation. A chemotherapy program was established with administration of a high dose of methotrexate plus citovorum factor, adriamycin and vincristine. Surgical removal of pulmonary metastases and other local recurrences was performed where and when possible.

The functional results were excellent in four and poor in the remaining patient. All of the patients rapidly achieved physical rehabilitation and developed a stable and painless gait.

This approach to the treatment of osteogenic sarcoma attempts to eliminate the primary tumor, the micrometastases and the overt metastatic disease, leaving the patient to follow as normal a life a possible, which is not the case when a high thigh amputation or a hip disarticulation is performed.     

Supracondylar Fractures of the Femur

Successful management of the distal femoral fracture is possible with adherence to the basic principles of anatomic reduction, stable fixation, and early motion. Closed management can achieve these goals in selected patients, but most supracondylar femoral fractures are better treated with operative reconstruction. Implant selection is determined on the basis of the characteristics of the fracture, the bone quality, the needs of the patient, and the experience of the surgeon. Surgical options include the angled blade plate, compression-screw systems, condylar buttress plates, intramedullary nails, external fixation, and modular distal femoral replacement. The author reviews the indications and techniques for using these devices.     

Bifurcation of the Distal Femur

Bifurcation of the femur has previously been reported in the literature in only 12 cases. Two more cases are added, and the etiology of this congenital anomaly is discussed.     

The Correlation Between Lateral Bowing Angle of the Femur and the Location of Atypical Femur Fractures

This study is the first to report the use of data on incomplete atypical femur fracture (AFF) to evaluate the curvature of femur and explore the relationship between lateral femoral bowing angle (FBA) and AAF location. In this study, we obtained 17 cases of incomplete AFF and calculated the accurate lateral FBA and location ratio of the incomplete fracture. Incomplete fracture location was defined as a percentage (length from lesion to greater trochanter tip/entire femur length %; greater trochanter tip: 0 %; femoral condyles: 100 %). A lateral FBA of 7° was set as the point of demarcation. Eleven femurs had a lateral FBA ≤ 7° (group 1), with a median lateral FBA of 4.75° (IQR 2.5–5.9°) and a median of incomplete AFF location at 25.2 % (IQR 23.4–30.1 %). Another six femurs had a FBA > 7° (group 2) with a median of 1.8° (IQR 10.2–14.3°) and a median location at 47.7 % (IQR 38.6–54.5 %). There was a significant statistical difference in location (p < 0.05) between the two groups. The rate of BP use was 87.5 % in group 1 which was higher than 60 % in group 2. There was some degree of positive correlation between the bowing angle and location in simple linear regression (r ² = 0.549, p < 0.001, ß = 1.789). AAFs located in diaphysis were associated with large lateral FBA. On the other hand, AAFs located in subtrochanteric region were more commonly found in femurs with smaller lateral FBA. In conclusion, the degree of the FBA was associated with AFF location.     

Post-Fracture Changes of the Femur Cortex

Roentgenograms of the femora were obtained in 21 patients who on average 10 years earlier had sustained a fracture of the shaft of one tibia. On the fracture side a slightly uneven “spotted” appearance could be detected in most patients. Also, the marrow canal was about 10 per cent wider in the femora of the fractured limb - this widening was unrelated to the time factor, indicating a permanent loss of endosteal bone.
