Comparative Study
Arthroscopic versus open rotator interval closure: biomechanical evaluation of stability and motion.
The purposes of this study were to investigate the differences between open and arthroscopic closure of the rotator interval (RI) on glenohumeral translation and range of motion. We also sought to determine if the addition of either an open or arthroscopic RI closure increases stability of the shoulder. ⋯ This study suggests that arthroscopic RI closure adds little to the overall posterior and inferior stability of the shoulder joint, although anterior stability may be improved. There is a potentially large loss of external rotation after either repair method.

With regard to the anatomic basis of Neer type 2 fractures of the distal part of the clavicle, a clavicle fracture is associated with a coracoclavicular conoid ligament disruption. We describe an arthroscopic-assisted surgical procedure to stabilize the fracture and reconstruct the ligament. Surgery is performed with the patient in the beach-chair position. ⋯ The intra-articular sutures are pulled out through the upper incision on top of the clavicle. Tightening of the 2 knots is performed at the same time. This arthroscopic-assisted surgery allows for total recovery of shoulder function, without the inconvenience of device migration or acromioclavicular joint lesions reported with other procedures.
