Materials and MethodsA 60-year-old female visited our ER following a fall down from motorcycle. Several attemptsat closed reduction under sedation, failed in the emergency room. X-ray showed great tuberosityfracture with anterior dislocation. So operation was performed. The shoulder was exploredthrough a muscle splitting incision to a standard deltopectoral approach. On exposing thehumeral head, a complete avulsion of the supraspinatus tendon with bony attachment wasfound. An avulsion of the greater tuberosity fragments was also noted. The posterior periostealsleeve was intact. The reason of irreducible anterior dislocation of shoulder is due to anteriorglenoid rim had deeply wedged into a triangular defect in the posterior humeral head. Then thedislocation was reduced the fractured tuberosity and the rotator cuff avulsion was repaired usinga double row repair technique. (The anchors and screw with multiple oblique Ethibond No. 2mattress sutures to the rotator cuff). Since 2008.July to 2010.Jan, 8 patients was diagnoseddislocated with greater tuberosity fracture and difficulity in reduction under regular technique.double row repair technique was perforemd and then follow up in outpatient department.ResultsAll patients were recovery to 85-96% ROM under average follow-up 7 months. X-ray showedwell union for fracture and good to excellent pain recovery.ã€Discussion】Closed reduction of an acutely dislocated shoulder is usually successful. The reported causes ofirreducible dislocation include bowstringing of the subscapularis or bicipital tendon; impactionof the greater tuberosity into a Hill—Sachs lesion; interposition of a ruptured subscapularis inthe glenoid rim. We reviewed 8 cases of irreducible anterior shoulder dislocation and repairboth rotator cuff tear with great tuberosity fracture using double row repair. We found thistechnique is useful and easy in fixation of greater tuberosity fracture with repairing rotator cufftear.FiguresPoster: 58Double Acetabular Wall: A Misleading Point for Hip Arthroplasty*Firooz Madadi - Akhtar Hospital - Tehran, Iran*Email: fmedadi@yahoo.comDespite the great attention focused on cup positioning in primary total hip arthroplasty (PTHA),it is surprising to find so few studies that have dealt with cup placement. One common problemthwarting the correct cup placement during PTHA is the existence of osteophytes which obscurethe anatomical landmarks. We evaluated 276 patients with hip complaints, using their plain x-rays and CT-scans. Among these, 57 underwent surgery.
