PURPOSE We measured the BMD of elderly patients with osteoporotic hip fracture in order to understand the relationship between BMD of each sites and hip fracture occurrence or the types, and also to suggest a reference point for starting an osteoporosis treatment program. MATERIALS AND METHODS From July 2007 to February 2010, we investigated total 147 elderly osteoporotic hip fracture patients over 65 years. For control group, 80 patients who were over 65-year-old and did not have any fracture were selected. BMD was compared at each site between each groups statistically. RESULTS In the comparison of femur intertrochanter and neck fracture groups, BMD of femur neck and trochanter areas and L2, L3 areas were significantly less in intertrochanteric fracture group. In the analysis according to the classification of intertrochanteric fracture, BMD of intertrochanter and Ward's triangle area were significantly less in unstable fracture group than stable one. Each of the fracture threshold of intertrochanteric and neck fracture group was -1.10 and -1.36 of the T-score in proximal femur, and -1.40 and -1.40 of the T-score in lumbar vertebrae. CONCLUSION To examine the BMD of both proximal femur and lumbar vertebrae areas is helpful to predict the hip fracture occurrence and the type of hip fracture. And for the prevention of hip fracture in elderly patients over 65 years, we propose that the aggressive treatment of osteoporosis should be started to prevent fracture for patients with a T-score less than -1.40.

We have reviewed 40 patients of acute acromioclavicular dislocation all treated by several operative procedure from January 1990 to July 1996. After about 12 months follow up period, we analyzed the relationship between the type of operation and the clinical results. Several operative mothods were demonstrated till now, but 4 techniques or their combinations are commonly used. Those are fixation of acromioclavicular joint, fixation of coracoclavicular ligament, resection of distal end of clavicle and dynamic muscle transfer. Modified Phemister technique, modified phemister technique with coracoclavicular fixation and modified Bosworth technique were used with or without repairment of coracoclavicular ligament at our hospital.
Modified Phemister technique showed less good results than those of other techniques especially when repair of the coracoclavicular ligamentwas not made, and the repair of the coracoclavicular ligaments or fixation of the coracoclavicular joint is an important factor affecting the final results.
Many different systems of classification have been used for fractures of the distal part of the femur, but no one system was so perfect as to describe all the types and to ease the fracture treatment.
Supracondylar-intercondylar fractures of the femurs should be treated separately from other fractures of the distal part of the femurs becasue of their intricate fracture shape involiving the joint surface and associated injuries about the knees.
Authors have experienced two cases of unusual supracondylar-intercondylar fracture. It put another complexion on the classification and treatment.
Therefore it was tentatively named as 5-part fracture of the distal femur, which is not described in any other classification ever proposed.
