Keeping in view, the post-operative complications of cannulated hip screw, we have undertaken a study in which fracture fixation was done by newly modified cannulated screws--variable length sliding compression screw (VLSC).
The VLSC screw has inner screw diameter of 6.5 mm and outer barrel diameter of 8.5 mm and it has two variable length's (a) 59 mm - 75 mm and (b) 76 mm - 110 mm (minimum length maximum length).
Then VLSC screw was assembled to extended "T" wrench and screw was advanced till 5 mm from subchondral bone.
RESULTS: In this study we evaluated results of VLSC Screw fixation in 15 cases of intracapsular fracture neck of femur.
In our series, we tried to compare VLSC screws to CCS screws.
