The Study Of Coracoacromial Ligament Morphology And Its Clinical Aspects

Background: The coracoacromial ligament (CAL) as an integral component of the coracoacromial arch, plays animportant role in shoulder biomechanics, joint stability, and proprioception thus maintains static restraint dueto its dynamic interactions with ligaments, muscles and bony elements around the shoulder joint. Age-dependentchanges due to chronic stress and cellular degradation cause thickening and stiffening of the CAL that maycontribute to a spectrum of shoulder pathology from capsular tightness to rotator cuff tear arthropathy andimpingement syndrome.Objectives: This study conducted to observe the different types of CAL and its relationship with coracoacromialveil.Materials and Methods: The study conducted on 50 upper limbs at Bowring & Lady Curzon medical college &research institute and Bangalore medical college & research institute. The upper limbs were dissected at theshoulder joint complex and acromion process and coracoid process were appreciated and coracoacromialligaments were appreciated for their types and morphometry.Results and Conclusion: Four types of CAL were observed in this study. These are Y shaped CAL in 12 (24%) upperlimbs, broad banded in 8 (16%), quadrangular band shaped in 25 (50%) and multiple banded in 5(10

Ossification of the Coracoacromial Ligament in Subacromial Impingement Syndrome: A Case Report

Here, a case of a 59-year-old man with rotator cuff tear and impingement syndrome caused by an ossified coracoacromial ligament is presented. Ossification of the coracoacromial ligaments can occur because of degenerative changes due to trauma or repeated stress, which can lead to impingement syndrome. Therefore, when coracoacromial ligament ossification is present, rotator cuff damage due to impingement syndrome should be considered. Here, we conducted arthroscopic subacromial decompression, removal of the ossified coracoacromial ligament, and supraspinatus and subscapularis tendon repairs. We achieved satisfactory surgical outcomes without relapse; therefore, we report this case with a literature review.

Comparative study of arthroscopic coracoacromial ligament augmentation and clavicular hook plate for treatment of acromioclavicular joint dislocation / 中华创伤杂志

Objective To compare the outcomes of arthroscopic coracoacromial ligament augmentation and clavicular hook plating in treatment of acromioclavicular joint dislocation.Methods From March 2008 to March 2012,47 patients with acute closed type Ⅲ-Ⅴ acromioclavicular joint dislocations underwent an arthroscopic repair with coracoacromial ligament augmentation and suture (ligament augmentation group,23 patients) and with AO clavicular hook plate (hook plate group,24 cases).Mean age of the patients (32 males and 15 females) was 34.8 years (range,17-45 years).There were 32 left and 15 right injuries.Postoperative outcome was assessed through radiographic examination,American Shoulder and Elbow Surgeon (ASES) score and Karlsson scoring method.Results Mean period of follow-up was 18 months (range,12-24 months).In ligament augmentation group ASES score improved from (28.7 ± 7.3) points preoperatively to (96.3 ± 6.9) points postoperatively (t =51.34,P ＜ 0.05).In hook plate group ASES score improved from (29.3 ± 7.6) points preoperatively to (83.6 ± 8.5) points postoperatively (t =43.78,P ＜ 0.05).Postoperative radiographic examination showed well joint reduction of all patients.Good and excellent results with the Karlsson score accounted for 96％ (22/23) in ligament augmentation group and 71％ (17/24) in hook plate group (x2 =9.05,P ＜0.05).Conclusions Efficacy of coracoacromial ligament augmentation and suture for the treatment of acromioclavicular joint dislocation is better than clavicular hook plate.Coracoacromial ligament augmentation and suture are associated with lower incidence of shoulder pain and shoulder activity limitation,shorter recovery time,fewer complications and early activities.

Treatment of Complete Acromioclavicular Joint Dislocation by Weaver and Dunn Method / 대한정형외과학회잡지

From March 1973 to May 1979 at Hanil Hospital, seven patients with acute complete disiocation and three patients with chronic complete dislocation of the acromloelavlcular Joint had been treated surgically by Weaver and Dunn method which combines resection arthroplasty of the acromioclavicular jolnt with flxation of the clavlcle In an anatomical position by suture of the acromial end of the shortened coracoacromial ligament into the medullary canal of the clavicle. The results were considerably good In both acute and chronic cases. Full range of motion was observed on average In eight weeks in most cases.
