Abstract:
OBJECTIVE: To introduce an operation of subscapularis slide from its origin and anterior release from its insertion for treatment of medial rotation contracture, subluxation and dislocation of the shoulder caused by obstetric brachial plexus palsy (OBPP). METHODS: Thirty-six cases with medial rotation contracture of the shoulder were diagnosed by measurement of the inferior glenohumeral angle, passive lateral rotation of the shoulder and plain radiographs. Subscapularis slide was performed in 24 cases with simple medial rotation contracture, and anterior release in 12 cases with complex contracture-medial rotation contracture combined with subluxation, dislocation, or other deformities of the shoulder joint. Systems of Mallet scoring and Gilbert grading for the shoulder were used to evaluate the postoperative shoulder function. RESULTS: With follow up for a minimum of six months, 32 cases got apparent gains from operations, accounting for 88.8% of the total operated on. The younger the child was, the better the result. Of 4 cases with no operative effects, 3 had no flexion of the elbow preoperatively, suggesting a poor recovery of the upper trunk of the brachial plexus; the rest one had no repair of the severed subscapularis tendon. CONCLUSIONS: Subscapularis slide and anterior release of the shoulder are effective for treatment of medial rotation contracture as well as its consequence of subluxation and dislocation of the shoulder in OBPP. The operative effect is related to children's age and the recovery extent of the upper trunk of the brachial plexus.
