(18) Achieving this goal using the arthroscope requires preoperative evaluation of the acromial morphology, planning of the dimensions of bony resection, a reproducible acromioplasty method with intraoperative evaluation of the adequacy of resection, and postoperative confirmation of the resulting acromial shape.
(19) The most common findings at operation were proliferative subacromial bursitis and an acromial protuberance.
(20) The distances from the acromial side of the AC joint to the lateral edge of the clavicle at its superior and inferior cortices were measured before and after surgery on anteroposterior radiographs.
Acromion
Definition:
(n.) The outer extremity of the shoulder blade.
Example Sentences:
(1) Six months later, she developed a plasma cell tumour of the left acromion diagnosed as an IgG kappa myeloma.
(2) Partial resection of the anterior undersurface of the acromion, excision of the coracoacromial ligament or of the lateral end of the clavicle (and most commonly a combination of all three measures), were the methods used to achieve decompression.
(3) The operative technique includes avoidance of a complete acromionectomy and an adequate suture of the deltoid muscle to the acromion after an acromioplasty.
(4) The flap interposed in this way between the greater tubercle of the humerus and the acromion functions in the same way as a double-bellied muscle and prevents displacement of the head of the humerus.

(6) Excision arthroplasty of the acromioclavicular joint and anterior acromioplasty is highly effective for impingement under the acromion, but only moderately effective where impingement is under the acromioclavicular joint.
(7) Of these N3 and N6 were highest in amplitude at the distal insertion of the brachioradialis and the distal end of the deltoid, respectively, and N9, at the acromion.
(8) The formation of spurs around the acromion and acromiocalvicular joint correlated highly with increased age of the patient and with chronic disease of the rotator cuff.
(9) Bone is resected by sweeping the cutter from lateral to medial and progressing anteriorly while maintaining the angle of the burr, using the angle of the posterior acromion as a guide.
(10) This case illustrates a developmental variant of the acromion resulting in apparent widening of the acromioclavicular joint space rather than discontinuity of the inferior cortices of the acromioclavicular joint.
