The primary goal in the treatment of an order patients with an intertrochanteric fracture is to obtain anatomical reduction and rigid fixation for the rapid mobilization, decreased mortality and restoration of function.

Many devices were developed for this purpose, especially of compression hip screw had gained considerable acceptance.

A retrospective study of clinical results of the 50 cases intertrochanteric fracture from March 1990 to January 1993 was performed.

The result were as follows;

1. Average age is 58 years and sex distribution is 31 cases of male, 19 cases of female.

2. Common cause of injury are slip down and traffic accident. Affected side is Rt 32 cases and Lt 18 cases.

3. According to the classification (of Boyd-Graffin), there are 14 case of Type I, 31 cases of Type II 2 cases of type III,3 cases of Type IV.

4. Among 50 cases, complication is encountered in 8 cases angular deformity (4 cases), limitation of motion(3 cases), infection(1 case).

5. After treatment of intertrochanteric fracture ; Neck-shaft angle of non-displaced fracture and comminuted fracture was an average 2 degree varus angular deformity. Vertical displacement of non-displaced fracture was an average 4.5mm and comminuted fracture was 5.0 mm. Medial displacement of non-displaced fracture was an average 3.5mm and comminuted fracture was 4.5mm.

6. Satifactory results could be obtained by open reduction and internal fixation with compression hip screw.
