ABSTRACT
BACKGROUND:Intertrochanteric femoral fractures are one of the most common fractures in old patients. How to effectively fix has a great chalenge for orthopedic surgeons. No consensus on which fixation method is optimal has been obtained in the academia. OBJECTIVE: To evaluate the clinical therapeutic effects and complications of minimaly invasive percutaneous proximal femur locking compression plate for senile stable intertrochanteric fractures. METHODS:From May 2010 to May 2012, 98 patients (34 males and 64 females) with stable intertrochanteric fractures were treated with minimaly invasive percutaneous proximal femur locking compression plate fixation. The mean age was 76 years (range, 59-93 years). The mean time between fractures and operation was 3 days (range, 1-5 days). Patients were folowed up regularly after treatment. Healing time, Harris score of hip function recovery and the occurrence of complications were evaluated. RESULTS AND CONCLUSION: Al patients were folowed up for 12-24 months. Al incisions obtained healing by first intention. Al fractures reached clinical healing, and the healing time was 12-20 weeks (16 weeks on average). There was no fixation failure and loosing, rotation, crispatura deformity or screw cutting the femoral head. The function of the hip joint was assessed according to the Harris scoring: excelent in 75 cases and good in 18 cases, with the excelent and good rate of 95%. These data verify that proximal femur locking compression plate can be a feasible alternative to the treatment of stable intertrochanteric fractures. The patients obtained satisfactory outcomes, with less complication, indicating that there is a good biocompatibility between the implant and elderly host.
ABSTRACT
BACKGROUND: In recent years, the method of bladder reconstruction is still at the experimental stage. Therefore, anatomical study is necessary for its clinical application.OBJECTIVE: To provide anatomical bases for the selection of proper spinal roots, the ideal level for cross anastomosis, and the identification of anterior roots of spinal nerves during bladder functional reconstruction with Achilles tendon reflexes.DESIGN: It was a single sample study with anatomical specimen as subjects.SETTING: The experiment was conducted in the department of orthopaedics of a municipal hospital.PARTICIPANTS: The experiment was completed in the Department of Anatomy, Second Military Medical University of Chinese PLA, from May 1999 to January 2000. Altogether 20 adult corpse specimens (14 males and 6females, 40 sides) were involved.INTERVENTION: The origin of spinal roots of the sacral plexus and sciatic nerve, the distribution of corresponding spinal root between the sciatic nerve and other nerves were followed up.MAIN OUTCOME MEASURES: Overlapping length, horizontal area, and relative position of anterior roots of L4-S4 spinal nerves in the dura mater.of S2 -4 anterior spinal roots originating from the spinal cord was higher than that of L4, L5 and S1 anterior spinal roots running through the dura; the cross-sectional area of L4(2. 19 ±0.39) mm2, L5(2.58 ±0.58) mm2 and S1(2.19 ± 0.42) mm2 anterior spinal roots was more than that of S2-4 anterior dentify their sequence at the terminal cone level than under this level.should be taken during bladder functional reconstruction with Achilles tendon level.
