<p>Two cases of medial migration of the hip screw in cases of cephalon-medullary nailing for the treatment of extra-articular proximal femoral fractures are reported. The first case was revised to hemiarthroplasty, that was subsequently complicated with infection and death of the patient, while the second was revised to a similar devise with favorable outcome. A review of the literature is performed in order to identify the contributing factors that result in the medial migration of the hip screw. Emphasis is given in further reporting of similar cases in order to abolish this potentially lethal complication.   </p>

High failure rates are expected in the treatment of osteoporotic proximal femoral fractures. A newly designed femoral neck locking dynamic hip screw has been developed to increase the fixation strength; a biomechanical examination was performed to prove its efficacy. Femoral surrogate specimens were used for the test. Unstable intertrochanteric fractures were created on specimens. Then these specimens were divided into two groups to test two different methods of fixation: (1) the conventional dynamic hip screw and (2) the new designed femoral neck fixation dynamic hip screw. For each specimen, the peak cyclic loading was 800 N, and a total of 20,000 cycles were applied. The vertical displacement, rotation around the long axis of lag screw, and the varus rotation around the center of femoral head between the two groups were compared at specific intervals. All the conventional dynamic hip screw constructs failed within 1000 cycles, while no gross mechanical failure was recorded for the femoral neck fixation dynamic hip construct even after 20,000 loading cycles. The mechanical test comparing the two constructs at the end of each 1000 loading cycles demonstrated that the femoral neck fixation dynamic hip screw construct is stronger than that of the conventional dynamic hip screw. For the fixation of proximal femoral fractures, the femoral neck fixation dynamic hip screw can provide a stronger support than what a conventional dynamic hip screw can do. At the same time, femoral neck can be a suitable site for the application of proximal locking screws.

Purpose. To identify factors predicting one-year mortality in patients on clopidogrel presenting with proximal femoral fractures. Methods. 9 men and 22 women aged 64 to 97 (mean, 81; standard deviation, 8) years who had been taking clopidogrel for ischaemic heart disease (n=15), cerebrovascular disease (n=6), or both (n=10) presented with proximal femoral fractures. The time from injury to operation, type of anaesthesia, treatment method, and postoperative complications were reviewed. One-year mortality was analysed using the Kaplan-Meier curve. Factors predicting one-year mortality were identified. Results. The fracture configurations of the 31 patients included intracapsular femoral neck fracture (n=17), intertrochanteric fracture (n=13), and subtrochanteric fracture (n=1). 30 of the patients underwent hemiarthroplasty (n=16), dynamic hip screw fixation (n=9) or intramedullary hip screw fixation (n=5). The remaining patient underwent conservative treatment owing to metastatic prostate cancer. Of the 30 patients who underwent surgery, clopidogrel was discontinued at least 7 days prior to surgery, with the mean delay to surgery being 8.4 (range, 2–16) days. No patient had excessive blood loss at operation, although 7 patients received a blood transfusion postoperatively. 13 (43%) patients developed postoperative complications. The one-year mortality was 26% (8/31). Univariate analysis showed that factors predicting one-year mortality were spinal anaesthesia (p=0.04), postoperative blood transfusion (p=0.03), postoperative complications (p=0.03), and delay to surgery (p=0.03). Multiple regression analysis showed that delay to surgery (p=0.03) was the only independent predictor of one-year mortality, with a hazard ratio of 1.357 (95% confidence interval, 1.03–1.79). Conclusion. Surgery should be performed as soon as possible in medically fit patients having proximal femoral fractures who are taking clopidogrel, as delay to surgery is associated with increased one-year mortality.
