The recovery depends upon many factors, including where the tear was located, how severe it was, and how good the surgical repair was. [ citation needed ] It is believed that it takes at least four to six weeks for the labrum to re-attach itself to the scapula bone (shoulder blade), and probably another four to six weeks to get strong.
The shoulder joint is made up of three bones: the shoulder blade (scapula), the collarbone (clavicle) and the upper arm bone (humerus). The acromion is a bony process at the end of the scapula. The shoulder is a complex mechanism involving bones, ligaments, joints, muscles, and tendons.
The Weaver–Dunn procedure is a type of surgery involved in the treatment of severe separated shoulders developed by James K. Weaver and Harold K. Dunn in the early 1970s. [ 1 ] The procedure is done to replace the coracoclavicular ligaments with the coracoacromial ligament .
The glenoid cartilage underneath the labrum in the glenohumeral (GH) joint is disrupted by glenolabral articular disruption. [5] The articulation of the humeral head inside the glenoid fossa of the scapula forms the GH joint itself, which is a synovial ball and socket joint.
After treatment and recovery, a previously dislocated shoulder may remain more susceptible to reinjury, especially in young, active individuals. Ligaments are stretched and may tear due to dislocation. Torn ligaments and other problems resulting from dislocation can increase the chance of repeated dislocation.
The glenoid labrum (glenoid ligament) is a fibrocartilaginous (but not fibrocartilage, as previously thought) structure attached around the rim of the glenoid cavity on the shoulder blade. The shoulder joint is considered a ball-and-socket joint .
A Type II AC separation involves complete tearing of the acromioclavicular ligament, as well as a partial tear (but not a full tear) of the coracoclavicular ligaments. [5] This often causes a noticeable bump on the shoulder and partial or incomplete dislocation. [11] [5] This bump is permanent. The clavicle is unstable to direct stress ...
Grade I is slight displacement of the joint, and a badly stretched or partially torn AC ligament. It has the normal separation of <4 mm. Grade II is a partial dislocation of the AC joint with a complete disruption tear of the AC joint and a partial disruption of coracoclavicular ligament. The AC gap is >5 mm. Grades I and II never require ...
