Habitual Posterior Dislocation of the Shoulder-Joint

Idiopathic Posterior Instability of the Shoulder Joint:Results of Operation with Posterior Bone Graft

“…A fairly extensive search of the literature for idiopathic posterior instability of the shoulder joint treated with a posterior bone graft revealed several reports all with favourable results (Hohmann 1933 Jones 1958, Galli 1959, Dimon 1967, Lindholm 1974 but in each report there were only one or two cases and the interval between the operation and the review was often less than a year. DePalma (1973), who has had greater experience, favoured a combined procedure with a bone graft or osteotomy of the neck of the scapula supplemented by tendon shortening and reported "no failures".…”

“…Such operations are: soft tissue operations (Sjovall 1944, Ekman 1948, Severin 1954, Boyd & Sisk 1972, English & Macnab 1974, Lindholm 1974; skeletal operations such as a posterior bone graft (Asplund 1942, Hindenach 1947, Fried 1949, Lindholm 1974 or an osteotomy of the glenoid cavity (Scott 1967, English & Macnab 1974 and combined procedures (Dimon 1967, Mclaughlin 1962, DePalma 1973. In the present series a combined procedure with a posterior bone graft and a raphe of the infraspinatus tendon or posterior capsule was chosen in four cases out of five and in the fifth only the bone graft was used.…”

The posterior bone block procedure in posterior shoulder instability

“…9 There are only a few reports of the posterior bone block procedure with small numbers of patients and short follow-up. [10][11][12][13][14] Osteoarthritis of the glenohumeral joint is a common late finding after recurrent anterior dislocation of the shoulder or stabilising procedures for this condition. [15][16][17] Several medium-and long-term radiological studies have shown high rates of osteoarthritis after surgery for recurrent anterior dislocation, regardless of the technique used.…”

Posterior Bone Grafting for Glenoid Defects of the Shoulder

“…The posterior bone block must be positioned extra-articularly, and it should extend approximately 5-10 mm over the posterior edge of glenoid. 52 Fried 53 was the first to report on the successful treatment of recurrent posterior dislocation with an extracapsular bone block. Since then, several other studies have corroborated these results.…”
