Abstract
A modified Kessel trans-acromial approach has been utilised in our Unit for decompression and repair of associated rotator cuff tear for all advanced impingement syndrome (Stage III). This preliminary report aims to review our results, and to assess the complications of this approach.
From 1996 to 1999, 22 consecutive patients who were treated surgically using a Trans-acromial approach for advanced impingement syndrome, were reviewed. The diagnosis of impingement syndrome was based on history, physical examination and Lignocaine impingement test, with either an ultrasound scan, arthrogram, or MRI. The modified trans-acromial approach was used involving splitting and raising a periosteal soft tissue flap over the acromion, followed by splitting the acromion in the coronal plane just behind the acromioclavicular joint, this allowed an extensive exposure of the rotator cuff and easy undercutting of the acromion.
20 patients were interviewed and examined specifically for this study, for an average follow up of 17 months. The other two patients were interviewed by telephone. The following parameters were studied: 1) functional assessment:[Constant’s Scoring system, and the UCLA Shoulder rating Scale. 2) Pain relief. 3) Patient satisfaction. 5) Return to preoperative activity. 6) Complication. The results were satisfactory in 17 patients (77%), and unsatisfactory in 5 pt (23%), one of which had cervical spondolysis, and two had new bony formation in the subacromial space. Pain relief was achieved in 78%. All patients returned to their preoperative occupation apart from one. Two patients had persisting impingement and had undergone revision subacromial decompression with satisfactory results.
The modified trans-acromial approach is an acceptable alternative to open anterior acromioplasty. It offers adequate decompression of the sub-acromial space, allowing a wide exposure and excellent visualisation of the rotator cuff. This facilitates cuff repair and mobilisation, while maintaining the integrity of the deltoid muscle, which accelerates postoperative rehabilitation.
