Osteoarthrosis after the Max Lange procedure for unstable shoulders

Abstract

Summary.Thirty-four patients were followed for a mean of 14.4

Osteoarthritis in shoulders with traumatic anterior instability: Preoperative survey using radiography and computed tomography

“…6,13 Many reports describe the postoperative incidence rate, as well as illuminate the nonoperative incidence as a result of traumatic dislocation or recurrent dislocation. 1,4,5,7,8,[10][11][12][15][16][17] Among the latter reports, most investigated the incidence of osteoarthritis in patients with recurrent dislocation scheduled for operative treatment. 1,5,10,11,15,17 Our investigation also focuses on the preoperative investigation in cases with recurrent dislocation.…”

“…6,13 Most previous studies determining the incidence rate included only patients previously treated operatively for recurrent dislocation. 1,5,7,8,10,12,15,16 No report analyzing preoperative osteoarthritis caused by dislocation or recurrent dislocation exists, although some articles describe the preoperative incidence rate. 1,5,10,11,15,17 The purposes of this report are to determine the incidence of osteoarthritis in shoulders with traumatic anterior instability for which surgery was scheduled and to detect the factors leading to the development of osteoarthritis.…”

Effectiveness of glenoid osteotomy in atraumatic posterior instability of the shoulder associated with excessive retroversion and flatness of the glenoid

“…In previous studies [8,17,22,36] progressive degeneration of the shoulder joint was mentioned as an undesirable consequence of glenoid osteotomy. We found mild degenerative changes in 25% of our patients after an average follow-up time of 5 years.…”

Operative Management of Anterior Glenohumeral Instability

“…In former literature bone-block procedures were presented, most of them not anatomically and placed extraarticular causing severe osteoarthritis in a high percentage [9,22]. But overtightening of the anterior capsule to reach stability in a glenoid-deficient instabile shoulder leads to an excessive loss of external rotation and therefore function ( Figure 13) and causes osteoarthritis when overhead activities are continued postoperatively [14,17].…”
