Right side was involved in 15 cases and. left in 2 cases. 3. On radiological finding Hill-Sachs lesion was found in 41%.0n pathological finding at operation of 15 cases, Bankart lesion was seen in 73%, Hill-Sachs lesion in 60%, glenoid erosion in 33%, capsular loosening in 33%, and capsular tear in 13%. 4. Limitation of external rotation compared with sound opposite side was measured in 12 to 40 with an average of 19.2 degrees. 5.
