Abstract |
Appropriate clinical examination and imaging may lead to early diagnosis and treatment
of the shoulder impingement syndrome, thus preventing progressing a complete tear of
rotator cuff. The impingement syndrome was caused by repeated entrapment and
compression of supraspinatus tendon between the proximal end of humerus inferiorly,
particularly its greater tuberosity and one or more component of coracoacromial arch
superiorly. The purpose of this study is to critically, evaluate the result of twenty-five
consecutive subacromial decompression with impingement syndrome and to assess the
diagnostic accuracy of MR imaging by using oblique coronal and oblique sagittal plan.
These patients were treated by arthroscopic subacromial decompression after their pains
failed to improve with conservative therapy over three month. The average follow up
was 25 month(range, 12 to 50). The mean age was 43 year old. The results were rated
based on subjective response and the UCLA shoulder rating scale of the result. Ten
patients(40%) were rated as excellent, 11 patients(44%) were good, while four
patients(16%) were fair. Radiologic evaluation suggested that the oblique sagittal plan of
MRI can be helpful in evaluation of bony and soft-tissue structure of the coracoacromial
arch and determining depth of bony resection. There were no infection or neurovascular
injury. In reviewing our result, it appears that the arthroscopic subacromial
decompression can be successful surgery for shoulder impingement syndrome and
diagnostic accuracy of supplementary oblique sagittal view of MRI was relatively higher
than oblique coronal view alone for appropriate surgical plan. |
