- PURPOSE
We compared and evaluated the unloading effect and the availability of four different types of lower limb casts.
MATERIALS AND METHODS
The subjects were ten healthy men who had no gait disturbances, neuromuscular disorder, and deformities of lower extremities. The mean age was 25.2years(22-29) and the mean weight was 62.6kg(53.9-69.1). The trials consisted of patellar tendon bearing(PTB) casts, short leg casts, long leg extension casts, and long leg 30° flexion casts. In each experiment, ten sets of measurements were taken with all subjects wearing four different types of lower limb casts and walking on a flat surface indoors. The load cell was placed on the sole of the foot and wrapped with casts so that we could measure the pressure of the sole during gait. The percentage of load reduction was calculated by comparing pressure of the soles and the bottom of the casts.
RESULTS
The unloading effects of the PTB, the short leg, the long leg extension, and the long leg 30° flexion casts were 23.8%, 19.5%, 25.5%, 27.9% of the loading. No significant difference of unloading effect was demonstrated between each four different types of lower limb casts(P>0.05).
CONCLUSION
Notwithstanding the clinical success of the lower limb casts in below knee fractures, the unloading effect of the casts was limited and any type of the casts did not show better unloading effects.

- PURPOSE
To compare and analyze the operative results of compression hip screw with those of gamma nail in the treatment of intertrochanteric fracture of femur.
MATERIALS AND METHODS
We performed retrospective analysis of intertrochanteric fracture of femur using the compression hip screws on 16 cases(stable 8 cases, unstable 8 cases) and compared the results with those of 21 cases(stable 5 cases, unstable 16 cases) of Gamma nail fixation. All the 37 cases were operated between April 1992 and May 1997 and followed for minimal 12 months. We permitted earlier weight bearing for the Gamma nail inserted group(1 week vs 3 weeks). We evaluated the operation time, bleeding amount, intraoperative and postoperative complications, bone union time, neck-shaft angle, and functional assessment by follow up radiographs and clinical results.
RESULTS
The average operation time was shorter in the Gamma nail group than in the compression hip screw group (97+/-23.3 compared with 117+/-35.9 minutes; p<0.05). The average amount of bleeding was lesser in the Gamma nail group than in the compression hip screw group (592 compared with 712 ml: p<0.05). The fracture union time and clinical function of two groups showed no statistically significant difference(p>0.05). During Gamma nail insertion, crack was developed in one femoral shaft which was united after bed rest and delayed weight bearing. Postoperative complications were coxa vara in 3 cases(1 case on Gamma nail, 2 cases on CHS) and cutting out of lag screw in 3 cases(1 case on Gamma nail, 2 cases on CHS), but showed no statistically significant difference between two groups(p=0.781).
CONCLUSION
Early weight bearing can be encouraged for the Gamma nail group and this seemed to be beneficial for the old patients. The Gamma nail fixation is considered as a useful method for the patients with intertrochanteric fracture if it is managed with proper technique.
