[Recurring anterior dislocation of the shoulder].

The paper makes a pathogenetic study of habitual dislocation of the shoulder, an analysis of the surgical techniques most widely used, and a review of the case histories collected at the G. Pini Orthopaedic Hospital for patients operated by the Bankart-Delitala method. After a short introduction on the general features of the lesion, and on normal human anatomy, the paper sets out the pathological anatomy, aetiopathogenesis and the radiological and clinical picture. Lastly consideration is given to the most widely known and diffused procedures for treatment, divided into: --Operations on the anterior capsule and the glenoidal pad. --Arthroereisis operations. --Tendinous transposition operations. --Tendinous suspension operations. The case histories cover nineteen subjects treated by the Bankart-Delitala method and rechecked at a distance ranging from a year to six years after the date of the operation. Statistical data are presented on age, sex, side affected and final functional data. These results comprise fifteen perfect cases with total recovery of activity and absence of pain. Three cases reported occasional pain, and one a slight sensation of hindrance of movements. No fresh dislocation. The Authors conclude by stressing the complete efficacy of the Bankart-Delitala method, as regards both functional recovery and the capacity for preventing further dislocations.
