In the article are presented data on the operative treatment of 52 patients (54 operations) with anterior instability of the arm joints. Patients have been distributed into 4 groups depending upon the character of intra-articular damages, revealed in the process of arthrotomy. Each group of patients was subjected to adequate operative intervention, based upon Bankart's method. The authors proceeded from the principle that the arm joint instability treatment should be aimed at removal of intra-articular damages. There have been restored integrity of the damaged cartilage cushion and the joint capsule, the capsule plasty and blocking of the anteroinferior joint sinus. The treatment tactics of the kind allowed to achieve the maximum stability of the arm joint and prevent postoperative recurrencies. Long-term results have been studied with 41 patient, no recurrencies have been noted. The operated limb function has been restored with the majority of the patients.
