Purpose: The aim of this retrospective study were to report the short-term results of inferior capsular shift procedure using splitting subscapularis and capsule for the patients who had shoulder instability and were apt to recur after arthroscopic stabilization procedure. Materials & Methods : Fifteen cases of instability of the shoulder were included with an average follow-up of 2 years (range: 1$~$3 years). There were 13 men and 2 women with an average age of 27years. Multidirectional instability was found in 4 cases, voluntary instability in 3 cases, bony Bankarte lesion in 2 cases and 6 cases were contact sportmen. Thirteen shoulders underwent the inferior capsular shifts and Bankart repairs and 2 shoulders without Bankart lesion underwent the inferior capsular shift only. Average 19 mm of shift (range: 10$~$25 mm) was done. Results : Fourteen patients showed good and excellent results with one subluxation and one positive apprehension test. Postoperative ranges of motions did not change in forward elevation, external rotation at side and external rotation at 90$^{circ}$ abduction (p>0.05). Conclusion : Inferior capsular shift procedure using splitting subscapularis and capsule can be helpful in shoulder instability patients who were high-risk group of recurrence with arthroscopic procedure.
