ABSTRACT
<p><b>OBJECTIVE</b>To discuss the curative effect of bone graft from trochanter with interlocking intramedullary nail for comminute fracture of femur.</p><p><b>METHODS</b>From January of 2009 to January of 2010, fifty patients with comminute fracture of femur were treated by the therapy of bone graft from trochanter with interlocking intramedullary nail, included 35 males and 15 females with an average age of 38.4 years old ranging from 28 to 50 years. According to AO/ASIF classification system, there were 15 cases of type B1, 20 of type B2, 8 of type B3, 7 of type C1.</p><p><b>RESULTS</b>All the patients were followed up for 12 to 24 months, averaged 14.4 months. All the broken femurs knitted in 4 to 6 months, the average period of knit was 5.6 months. The injured legs with normal movement in knees,which had no infection, vascellum-nerve injury and anchylosis in knees. According to Merchan knee rating scale, the results were excellent in 25 cases, good in 20, fair in 3 and poor in 2, and the excellent and good rate was 90%.</p><p><b>CONCLUSION</b>Bone graft from trochanter with interlocking intramedullary nail, which has a virtue of small injury, less blood loss, high rate of bone knit, perfect functional recovery, is a preferable therapy of fresh fracture of femur.</p>

<p><b>OBJECTIVE</b>To evaluate the feasibility of hamstring autograft anterior cruciate ligament reconstruction with hamstring tendons insertion on tibia preserved and an implant fixation technique of hamstring tendons knot and bone bolt press-fit.</p><p><b>METHODS</b>Twenty cases of injured anterior cruciate ligament were reconstructed. There were 15 males and 5 females with the average age of 22 years old. Ten left knees and 10 right knees were involved. Hamstring tendons were taken, and pretension was performed. Tibial tunnel and femoral tunnel were prepared,and the femoral tunnel was a frame of narrow inside and wide outside. The hamstring tendons knot and bone bolt were pulled inside of femoral tunnel. The tendons distal of tendons knot were brought to pass the femoral tunnel, joint capsule and another tibial tunnel. Then, the tendons distal of tendons knot were tightened together with the part of hamstring tendons of which the insertion were on tibia. After the operation, the knee was fixed at a flexion of 45 degrees by brace.</p><p><b>RESULTS</b>The patients were followed up for 8 to 24 months. The function of troubled knees was evaluated by Lysholm knee functional scale. The average knee score were 61.5 +/- 4.6 and 92.5 +/- 3.7 respectively before and after operation, and the difference was statistically significant (P < 0.05).</p><p><b>CONCLUSION</b>Hamstring tendons insertion on tibia preserved and an implant fixation technique of hamstring tendons knot and bone bolt press-fit was biological fixation for anterior cruciate ligament reconstruction with hamstring. The advantage of this method was avoidance of using high cost material for fixation,which lessened spending for the patients. And it was also benefit for tendon-bone healing.</p>
