What's the difference between acromion and subacromial?
Acromion
Definition:
(n.) The outer extremity of the shoulder blade.
Example Sentences:

(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.
(11) Intra-articular fusion methods, often combined with incorporation of the acromion into the fusion mass, are now the favored techniques.
(12) Through its ability to evaluate the individual components of the rotator cuff, the labral-capsular complex, the subacromial and subdeltoid spaces, and the glenoid, humerus, clavicle, and acromion, MRI provides a means of comprehensively evaluating the shoulder.
(13) Since 1981 the simpler approach of Neer without resection of acromion has been used (for synovectomy as well as for prosthetic replacement) with an easier postoperative management and equally good results.
(14) The dislocation is termed "anterior" because the clavicle is anatomically more proximal than the acromion.
(15) They differ from each other mainly in the glenoid piece pattern which may be sealed only to the glenoid cavity or also fixed onto the acromion.
(16) The MRI allows to delimit the lesion, and the hypointense signal in T1 and T2 weighted sequences directs to a fibrosis in the area between the end of the clavicle and the acromion.
(17) Treatment of experimental distal subluxation in the shoulder joint was achieved by transposition of the coracoacromial ligament and its bony attachment from the acromion to the lesser tuberosity of the humerus.
(18) After radiographic and histological analysis, we found that in the specimens that had a partial tear of the cuff the undersurface of the acromion was almost intact.
(19) The operation on cadaver bone and the simulation of acromion movement in a computer model demonstrate an increase of subacromial space more than 1 cm after wedge excision with cranial base of 5 mm and ventral base of 3 mm.
(20) This forms a living interposition material between the acromion and the greater tuberosity of the humerus, forming a real "three-bellies" muscle resisting the ascent of the humeral head.
Subacromial
Definition:
(a.) Situated beneath the acromial process of the scapula.
Example Sentences:
(1) A case is reported involving a 29-year-old man who developed scapular osteomyelitis following subacromial corticosteroid injection.
(2) (f) Fluid is not detected in subacromial-subdeltoid bursae.
(3) A random prospective comparison was conducted of 20 patients who underwent arthroscopic subacromial decompression or open acromioplasty as treatment for impingement syndrome.
(4) Causes of shoulder pain include supraspinatus tendinitis (the most common), bicipital tendinitis, impingement syndromes, supraspinatus rupture, subacromial bursitis, arthritis, frozen shoulder, and various conditions that refer pain to the shoulder.
(5) Clinical arthroscopic evaluation of the subacromial space was correlated with gross anatomical dissections of 12 fresh cadaver shoulders and a review of the pertinent anatomical and surgical literature.
(6) The subacromial space must be searched for loose bodies.
(7) Arthroscopic subacromial decompression is an alternative to open anterior acromioplasty in the treatment of chronic stage II impingement syndromes prior to the development of full thickness rotator cuff tear.
(8) Surgical treatment can be recommended for younger individuals, manual workers, and sportsmen, and rarely for cosmetic reasons, or when a subacromial impingement due to a disturbing proximal tendon stump is present.
(9) In 51 patients (27-67 years) with subacromial impingement syndrome, an acromioplasty according to Neer was performed.
(10) We found them to represent a major health problem, with an overall prevalence of 37.8%, the predominant diagnoses being subacromial shoulder pain (6.7%), neck pain (6.5%), low back pain (6.3%), osteo-arthrosis (8.5%), and arthralgia (4.9%).
(11) All patients exhibited clinical evidence of subacromial impingement, which was confirmed at surgery.
(12) Incomplete thickness rotator cuff tears (ITRCT) adjacent to the bursal sac were diagnosed preoperatively by subacromial bursography and confirmed by surgical exposure.
(13) A peribursal fat plane was poorly defined or absent in 49%, and fluid in the subacromial-subdeltoid space was found in 20%.
(14) Surgery in the subacromial space resulted in a complication rate of 0.76%.
(15) The subacromial joint is an area which is particularly predisposed to chronic tendon deterioration.
(16) Axial CT scans allow the depiction of subacromial compartment structures that cannot be demonstrated by US.
(17) We have used this position for over 50 consecutive patients for arthroscopic debridements, arthroscopic subacromial decompressions, and arthroscopic shoulder stabilizations.
(18) Arthroscopic evaluation of the glenohumeral joint and subacromial bursa has enabled the physician to increase both diagnostic and management skills.
(19) In some patients, manifestations of subacromial-subdeltoid bursitis was present.
(20) Increased signal intensity in the supraspinatus tendon on proton density-weighted images without a corresponding increase on T2-weighted images, the presence of small amounts of fluid in the subacromial space, and the lack of preservation of the subdeltoid fat plane are common findings in asymptomatic shoulders and by themselves are poor predictors of rotator cuff disease.
