The relative strengths of the rotator cuff muscles. A cadaver study.

We studied five cadaver shoulders to determine the strength relationship of the four rotator cuff muscles. The mean fibre length and volume of each muscle were measured, from which the physiological cross-sectional area was calculated. This value was used to estimate the force which each muscle was capable of generating. The lever arm of each muscle about the humeral head was then measured and the moment exerted was calculated. The strength ratios between the muscles were more or less constant in the five specimens. Subscapularis was the most powerful muscle and contributed 53% of the cuff moment; supraspinatus contributed 14%, infraspinatus 22% and teres minor 10%. The force-generating capacity of the subscapularis was equal to that of the other three muscles combined.

Massive rotator cuff tears treated by a deltoid muscular inlay flap.

We reviewed 20 patients with a painful massive, irreparable rotator cuff tear, classified as type III according to Gerber (11). They were all treated with an open partial acromionectomy, an attempt for primary repair and an anterior deltoid muscle inlay flap, as described by Apoil and Augereau. After minimum follow-up of 12 months (average 23.5 months) 17 out of 20 patients were satisfied and better, and the UCLA shoulder scoring (9) improved from an average of 9.35 to an average of 25.7 (max. of 35). Pain and function improved in all patients, with an average of 4.35 and 4.00 points respectively. Active forward flexion improved in 17, and strength of forward flexion improved in 15 patients. Our results were compared with those of Apoil and Augereau, and with the results obtained by other authors after open or closed acromioplasty and cuff tear debridement. This retrospective study tries to give a critical view of this French technique, and concludes that, although no negative effect can be demonstrated by the use of a deltoid muscle flap, a definite advantage cannot be proved.

Ultrasonography in lesions of the rotator cuff and biceps tendon.

Ultrasonography (US) of the shoulder joint was performed in 88 patients, 15 of whom were referred for surgery. US was made with a real-time linear-array scanner, provided with a transducer of 7.5 MHz. Subsequently, all patients underwent single-contrast arthrography of the shoulder. When compared with the arthrographic findings, diagnosis by US showed 21 true positive, 3 false positive, 57 true negative and 7 false negative cases of a full-thickness tear of the rotator cuff. Small tears (2 cm or less in diameter) may be the most difficult to assess. US readily revealed biceps tendinitis and rupture of the biceps tendon, as well as fluid collection in the bursae above the rotator cuff tendons.

Semiconstrained total shoulder arthroplasty for glenohumeral arthritis and massive rotator cuff tearing.

Each of 6 patients (7 shoulders) underwent semiconstrained total shoulder arthroplasty for glenohumeral arthritis, subluxation, and extensive rotator cuff tearing to obtain a more balanced joint and achieve consistent pain relief. A hooded glenoid component (Neer 600%) was used to contain the humeral head within the joint. Patients were followed for an average of 69 months (range, 26-125 months) or to revision surgery and were assessed clinically and radiographically. All patients experienced improvement with respect to pain; on average, active elevation and external rotation decreased to 44 degrees and 43 degrees. On radiographic evaluation, 3 of the glenoid components were seen to have complete radiolucent lines and 1 case showed a shift in component position. Five shoulders had anterior-superior joint subluxation. According to the shoulder score rating system of Neer, all but 1 of the shoulders were rated as unsatisfactory or unsuccessful at final follow-up. Two patients have undergone revision surgery for subluxation or glenoid loosening. We cannot recommend this method of treatment.

[Clinical examination of lesions of the rotator cuff].

Although unable to reach any formal conclusions, clinical examination remains an essential prerequisite in the assessment of a rotator cuff lesion, as it guides the diagnosis, evaluates the severity of the functional impairment and often the extent of the lesions and eliminates the differential diagnoses. The principal clinical tests of shoulder conflict are recalled, but as they are painful, they should only be performed at the end of a complete clinical examination.

Subacromial-subdeltoid lipoma arborescens associated with a rotator cuff tear.

A 44-year-old man presented with lipoma arborescens of the right shoulder, associated with a rotator cuff tear. MRI revealed villous proliferations with signal intensity of fat on all pulse sequences. At surgery, this bursa was found to contain moderately yellow cloudy fluid without fat globules. Histological examination of the lesion showed subsynovial accumulation of mature fat cells.

Open versus arthroscopic treatment of chronic rotator cuff impingement.

We report the results of 238 consecutive patients who underwent in total 261 acromioplasties because of chronic rotator cuff impingement. The procedure was performed either in conventional open technique (80) or arthroscopically (181). Two years (1-10) after the operation 68% of the patients treated with the open technique had an excellent or good result compared 82% of the patients treated arthroscopically by an experienced arthroscopic surgeon. Compared to the open technique, the arthroscopic procedure had a statistically significant superior result concerning outcome, operating time and hospital stay. Arthroscopic procedures performed by less experienced surgeons had inferior results.

Acromial enthesopathy and rotator cuff tear. A radiologic and histologic postmortem investigation of the coracoacromial arch.

Changes of the coracoacromial ligament (CAL) at its insertion into the undersurface of the acromion were studied radiologically and histologically in 76 autopsy specimens. Two changes were noted: (1) a downward, bony projection of the acromion, an anatomic variant limited to the area covered by the CAL, which might reduce the height of the subacromial compartment, and (2) a thickened layer of fibrocartilage, constituting a potential cause for narrowing of the subacromial space. The former might act as a predisposing factor for the impingement syndrome, whereas the latter could develop in response to pressure from constituents of the subacromial compartment. The acromial spur was a result of enchondral bone formation. A possible correlation between these changes and rotator cuff tears was investigated. The incidence and severity of cuff tears increased with age. However, there was no correlation between aging and degenerative changes of the undersurface of the acromion, except possibly in very advanced cases. Rotator cuff tears are unlikely to be initiated by impingement; rather, they develop as an intrinsic degenerative tendinopathy.

Repairs of the rotator cuff. Correlation of functional results with integrity of the cuff.

We evaluated the results of 105 operative repairs of tears of the rotator cuff of the shoulder in eighty-nine patients at an average of five years postoperatively. We correlated the functional result with the integrity of the cuff, as determined by ultrasonography. Eighty per cent of the repairs of a tear involving only the supraspinatus tendon were intact at the time of the most recent follow-up, while more than 50 per cent of the repairs of a tear involving more than the supraspinatus tendon had a recurrent defect. Older patients and patients in whom a larger tear had been repaired had a greater prevalence of recurrent defects. At the time of the most recent follow-up, most of the patients were more comfortable and were satisfied with the result of the repair, even when they had sonographic evidence of a recurrent defect. The shoulders in which the repaired cuff was intact at the time of follow-up had better function during activities of daily living and a better range of active flexion (129 +/- 20 degrees compared with 71 +/- 41 degrees) compared with the shoulders that had a large recurrent defect. Similar correlations were noted for the range of active external and internal rotation and for strength of flexion, abduction, and internal rotation. In the shoulders in which the cuff was not intact, the degree of functional loss was related to the size of the recurrent defect.(ABSTRACT TRUNCATED AT 250 WORDS)

[Use of digital subtraction arthrography in lesions of the rotator cuff--comparison with ultrasound].

60 patients with suspected lesion of the rotator cuff were examined by digital subtraction arthrography and the results were compared to ultrasound. The dynamic study of digital subtraction arthrography visualised in 22 of 23 complete or incomplete cuff tears the exact location of the extravasation of the contrast medium. All diagnoses were confirmed by surgery. Problems of conventional arthrography were not seen by the digital method.

The relationship of the glenohumeral joint capsule to the rotator cuff.

The glenohumeral joint capsules of 23 shoulders in which the rotator cuff was not torn were studied by gross dissection and histologic methods. The cuff tendons were resected, leaving the intact capsule attached to the bones. This dissection method provided a unique overview of the capsule in situ and allowed the areas of cuff tendon and muscle attachment to be mapped. The capsule was found to be a continuous cylinder between humerus and glenoid. On approximately one-third of the capsule (the portion adjacent to the humeral tuberosities), tight insertions of cuff tendons were noted. The superior segment between subscapularis and supraspinatus contained the coracohumeral ligament. This segment appeared to reinforce the cuff through a transversely oriented band similar to the glenohumeral ligaments.

Self-assessment questionnaires document substantial variability in the clinical expression of rotator cuff tears.

The goal of this investigation was to document the variability in the clinical expression of full-thickness rotator cuff tears with practical and standardized patient self-assessment tools. One-hundred twenty-three consecutive patients with full-thickness cuff tears diagnosed by standard cuff-imaging methods (sonography, arthrography, or magnetic resonance imagery) assessed their own shoulder function and health status with the Simple Shoulder Test and the Short Form 36, respectively. As a group, these patients were substantially compromised in their ability to perform the functions of the Simple Shoulder Test and in the Short Form 36 scales of physical role, physical function, and comfort. As individuals, however, their self-assessments varied widely. The standard deviations were often greater than 50% of the mean and the range of responses often covered the entire scale from the minimum possible score to the maximum possible score. These results show the importance of documenting the clinical expression of cuff tears in patients at initial evaluation and when treatment is being considered. The results also show the practicality of standardized self-assessment questionnaires in such documentation.
