Factors Influencing the Restoration of Acromiohumeral Distance of Immediate Postoperative Period in Patients Who Have Rotator Cuff Repair Surgery with Large-to-Massive Rotator Cuff Tears / 대한스포츠의학회지

ABSTRACT

The aim of the present study was to evaluate the degree of restoration of acromiohumeral distance of immediate postoperative period in patients who have rotator cuff repair surgery with large-to-massive rotator cuff tears and to find clinical and radiologic factors influencing this. Fifty four patients who had arthroscopic rotator cuff repair with available postoperative magnetic resonance images done within postoperative one week were included. Retrospective review of the medical data and radiologic images was done. It was revealed that acromiohumeral distance of immediate postoperative period was smaller in patients with larger sized rotator cuff tears, more retraction of the torn end and narrower preoperative acromiohumeral distance. The degree of inferior migration of the humeral head which could be obtained through the surgery alone was more in patients who have more difference between acromiohumeral distance measured on preoperative standing simple radiography and acromiohumeral distance measured on preoperative magnetic resonance image.
