- Rotator Cuff Tear - Discussion:
- indications for RTC tear:
- shoulder pain (especially night pain);
- symptoms which cause loss of function or quality of life;
- failure of NSAIDS and formal physical therapy;
- failure of series of marcaine / steroid injections;
- full passive ROM pre-op is necessary for a successful operation (rule out frozen shoulder);
- relative contra-indications:
- superior migration of humeral head (which indicates massive rotator cuff tear);
- as noted by G.M. Gartsman (1997), all patients w/ radiographic superior migration of the humeral head had a poor result;
- deficient deltoid, subscapularis, and/or teres minor (either by clinical exam or by MRI) are more likely to lead to poor results;
- Acromioplasty and Subacromial Dissection: 
- w/ a potential irrepairable cuff tear, consider leaving the CA ligament intact;
- incision is then deepened to expose subacromial bursa, which is opened, allowing limited view of underlying rotator cuff;
- exposure may be improved by elevating acromion w/ small right angled retractor distracting humeral head downward, & resecting
CA ligament (which is accompanied by acromial branch of thoracoacromial artery);
- Surgical Exposure:
- ref: Atrophy of the deltoid muscle following rotator cuff surgery.
- Controversies: Do we always need a subacromial decompression?
- in the report by BA Goldberg et al, the authors evaluated on shoulder function at a minimum of 2 years after 27 full thickness RC repairs were done
w/o deltoid detachment, acromioplasty, or section of CA ligament;
- 8 of 12 individual Simple Shoulder Test functions were significantly improved after the procedure;
- there also was a significant improvement in the Short Form-36 comfort, physical role function and mental health scores;
- the authors conclude that when done without acromioplasty, cuff repair avoids the possibility of deltoid detachment, altered
deltoid mechanics, anterosuperior instability, and tendon scarring to the cancellous undersurface of the acromion;

- Assessment of Cuff Tear: (see management of
massive rotator cuff tear);
- Additional Considerations:
- arthroscopic repair techniques
- distal clavicle excision: (w/ concomitant arthrosis);
- greater tuberosity debridement:
- prominent tuberosity can be excised if there is further impingment;
- biceps tendon:
- w/ obvious pathology of the long head of the biceps, consider proximal release of the tendon w/ or w/o tenodesis;
- references:
- To detach the long head of the biceps tendon after tenodesis or not: outcome analysis at the 4-year follow-up of two different techniques.
- Mobilization of Rotator Cuff:
- when mobilizing the rotator cuff, it is first useful to pass a "traction" suture thru the muscle (using a Kessler type stitch);
- this allows the cuff to be pulled forward under tension without damaging the muscle;
- place a blunt right angle retractor underneath the acromion and to apply traction to the forearm inorder to widen the exposure;
- the surgeon can then pass his finger above and below the muscle, freeing up adhesions;
- superior capsular release:
- superior capsular release and rotator interval-coracohumeral ligament release is performed when needed to allow a low-tension reduction of the
supraspinatus tendon to its anatomical position;
- Restoration of the Foot Print
- Rotator Cuff Repair Techniques:
- Deltoid Repair:
- both the superficial and deep fascial layers of the deltoid must be included in the suture repair of the deltoid to the acromion (thru acromial drill holes);
- consider using a Mason-Allen stitch thru the deltoid muscle;
- Post Op Care:
- with rotator cuff tears, passive range of motion may begin on day 1, and active assist exercises at week four;
- consider early active assited elevation and external rotation in the supine position;
- Outcomes:
- in the report by RH Cofield et al. 2001, 105 shoulders with a chronic rotator cuff tear underwent open surgical repair and acromioplasty between 1975 and 1983;
- patients were followed for an average of 13.4 years (range, two to twenty-two years);
- there were 16 small tears, 40 medium tears, 38 large tears, and 11 massive tears;
- tears were repaired directly (72 tears), by V-Y plasty (12), by tendon transposition (twenty), or by reinforcement with a fascia lata graft (one);
- long head of the biceps had been previously torn in eleven shoulders and was tenodesed in three other shoulders. In fifty-six shoulders, the distal
part of the clavicle was excised for treatment of degenerative arthritic changes, often associated with osteophyte formation;
- satisfactory pain relief was obtained in 96 shoulders (p < 0.0001);
- there was significant improvement in active abduction (p < 0.001) and external rotation (p < 0.007) as well as in strength in these directions of movement;
- at the latest follow-up evaluation, the result was rated as excellent for 68 shoulders, satisfactory for 16, and unsatisfactory for 21;
- tear size was the most important determinant of outcome with regard to active motion, strength, rating of the result, patient satisfaction, and need for a reoperation;
- older age, less preop active motion, preoperative weakness, distal clavicular excision, and a transposition repair technique were all associated w/ larger tear size.
