MR imaging of sports injuries to the rotator cuff.

Impingement pain and rotator cuff injury are common in athletes, particularly in overhead throwers. The cuff can be injured in these patients in the typical location in the anterior supraspinatus tendon and near the junction of the supraspinatus and infraspinatus tendons. The cuff tears in athletes are usually small, articular surface partial-thickness tears. The posterior cuff tears in overhead throwers are seen best at MR arthrography with the arm in abduction and external rotation. Other abnormalities, such as instability lesions or labral fraying, can be associated with rotator cuff tears in athletes.

Revision rotator cuff repair: factors influencing results.

BACKGROUND: Revision rotator cuff repair is a surgical challenge, and the results have generally been inferior to those of primary repair. We examined the results of revision rotator cuff repair in a large series of patients and assessed which subgroups of patients had the greatest chance for a satisfactory functional outcome. METHODS: A revision rotator cuff repair was performed in eighty patients after the failure of a previous operative repair. The average age of the patients at the time of the revision was fifty-nine years. Prior to revision, the average pain score was 7.4 points (with 0 points indicating no pain and 10 points, severe pain) and the active range of motion of the shoulder averaged 105 degrees of elevation, 39 degrees of external rotation, and internal rotation to the eleventh thoracic vertebra. All patients underwent repeat repair of the rotator cuff tendons to bone. Additional procedures included revision acromioplasty (fifty-three patients; 66%) and distal clavicular excision (twenty-six patients; 33%), among others. RESULTS: After an average duration of follow-up of forty-nine months, the result was rated as satisfactory (excellent, good, or fair) in fifty-five patients (69%) and as unsatisfactory (poor) in twenty-five (31%). At the time of the latest follow-up, the average pain score had improved to 3.0 points and the active range of motion averaged 130 degrees of elevation, 53 degrees of external rotation, and internal rotation to the tenth thoracic vertebra. Improved results were associated with an intact deltoid origin, good-quality rotator cuff tissue, preoperative active elevation of the arm above the horizontal, and only one prior procedure. All seventeen patients who met all four of these criteria had a satisfactory result. CONCLUSIONS: The results of revision rotator cuff repair are inferior to those of primary repair. While pain relief can be reliably achieved in most patients, the functional results are improved principally in patients with an intact deltoid origin, good-quality rotator cuff tissue, preoperative elevation above the horizontal, and only one prior procedure.

Chronic massive rotator cuff tears: evaluation and management.

Most studies of rotator cuff repairs report high success rates. However, the majority of these studies combine the results of surgical management of rotator cuff tears of various sizes; few published reports specifically evaluate the management of chronic massive tears. Chronic massive rotator cuff tears may be acute traumatic, chronic atraumatic, or acute-on-chronic. A detailed history and thorough physical examination often are sufficient to establish the diagnosis. Radiographic evaluation can reveal osseous changes suggestive of pathology. Magnetic resonance imaging can determine the size of rotator cuff tears and status of the muscles but generally is not necessary for patients who are not candidates for surgery. Chronic massive rotator cuff tears without glenohumeral arthritis can be managed nonsurgically or with sub-acromial debridement, rotator cuff repair, or rotator cuff reconstruction. However, treatment of these patients is challenging, and results are comparatively inferior to those of treating patients with smaller rotator cuff tears.

The bubble sign: an arthroscopic indicator of an intratendinous rotator cuff tear.

Intratendinous tears of the rotator cuff are, by definition, difficult to diagnose due to the absence of overt tendon disruption on both the bursal and articular surface of the rotator cuff. The authors describe the bubble sign, a bulging expansion of the rotator cuff tendon following injection of saline into the suspected lesion, as a useful indicator of an intratendinous tear of the rotator cuff.

The treatment of failed rotator cuff repairs.

Results following surgical management of failed rotator cuff tears are clearly inferior to those obtained in the treatment of primary repairs. Conservative management may be the treatment of choice in selected patients with failed rotator cuff repairs. The primary goal for revision rotator cuff surgery should be relief of pain, not improvement in function. If the level of pain is manageable, and the patient is functioning with respect to activities of daily living, additional surgery may not be helpful. As there are multiple etiologies associated with failure of the initial repair, each patient should be carefully evaluated on an individual basis to determine if a subsequent procedure would be appropriate. Repeat repair is more likely to succeed in patients with an intact and functioning deltoid, an intact lateral portion of the acromion, and good quality of rotator cuff tissue. Conversely, patients who have had a lateral or radical acromionectomy, a detached or nonfunctioning deltoid, or poor quality of remaining rotator cuff tissue are less likely to have a successful result after repeat repair. It is evident that some of the factors associated with failure are avoidable. As the best chance for a successful result is at the time of the primary repair, the following points will briefly review these factors. The skin incision should be made in the flexion creases which are perpendicular to the deltoid fibers. The deltoid origin should be meticulously protected during the repair and lateral or radical acromionectomy should not be performed. Adequate anterior acromioplasty is essential for removal of the impingement lesion and to prevent subsequent wear on the repaired cuff tendon. The acromioclavicular joint should be evaluated preoperatively and treated as indicated at the time of the surgery. Adequate release of adhesions and mobilization of rotator cuff tissue should be performed using the coracohumeral ligament release and interval slide when necessary. The rotator cuff should be repaired to bone using tendon to bone sutures and/or secure suture anchors. In large and massive tears, there appears to be a role for the reattachment of the coracohumeral ligament. Early phase I range of motion should be initiated following rotator cuff repair and early resistance exercise with weights should be avoided.

Association of a large lateral extension of the acromion with rotator cuff tears.

BACKGROUND: Factors predisposing to tearing of the rotator cuff are poorly understood. We have observed that the acromion of patients with a rotator cuff tear very often appears large on anteroposterior radiographs or during surgery. The purpose of this study was to quantify the lateral extension of the acromion in patients with a full-thickness rotator cuff tear and in patients with an intact rotator cuff. METHODS: The lateral extension of the acromion was assessed on true anteroposterior radiographs made with the arm in neutral rotation. The distance from the glenoid plane to the lateral border of the acromion was divided by the distance from the glenoid plane to the lateral aspect of the humeral head to calculate the acromion index. This index was determined in a group of 102 patients (average age, 65.0 years) with a proven full-thickness rotator cuff tear, in an age and gender-matched group of forty-seven patients (average age, 63.7 years) with osteoarthritis of the shoulder and an intact rotator cuff, and in an age and gender-matched control group of seventy volunteers (average age, 64.4 years) with an intact rotator cuff as demonstrated by ultrasonography. RESULTS: The average acromion index (and standard deviation) was 0.73 +/- 0.06 in the shoulders with a full-thickness tear, 0.60 +/- 0.08 in those with osteoarthritis and an intact rotator cuff, and 0.64 +/- 0.06 in the asymptomatic, normal shoulders with an intact rotator cuff. The difference between the index in the shoulders with a full-thickness supraspinatus tear and the index in those with an intact rotator cuff was highly significant (p < 0.0001). CONCLUSIONS: A large lateral extension of the acromion appears to be associated with full-thickness tearing of the rotator cuff.

Margin convergence of the posterior rotator cuff to the biceps tendon.

Massive rotator cuff tears can often be repaired arthroscopically with satisfactory results. Tear pattern recognition, knot security, and loop security are essential in the repair of large and massive rotator cuff tears. In the case of a massive U-shaped tear, with a contracted immobile supraspinatus and a deficient rotator interval, a type of margin convergence technique can be used. This technique allows for the partial closure of the rotator cuff defect along with the proximal advancement of the posterior cuff by securing the posterior leaf of the cuff tendon to the tendon of the long head of the biceps brachii. Because of the mechanical effect of strain reduction in margin convergence, this procedure decreases the strain at the margin of the posterior cuff, thereby protecting its repair to bone. Our goal with this procedure is not to obtain healing of the cuff to the biceps, but to optimize the conditions for healing of the rotator cuff to bone.

[Puncture-lavage-infiltration of calcifying tendinitis of the rotator cuff].

Calcifying tendinitis of rotator cuff is a common and evolutive pathology of the shoulder. This article supports the efficiency of imaging-guided needle puncture trituration and lavage in rotator cuff calcifications after failure of medical treatment. Overall efficiency of this economical ambulatory treatment ranges in the literature from 49 to 100 % and no complication is noted. In our opinion this technique should be used before arthroscopic or surgical removal of the calcifying tendinitis.

Replacement arthroplasty of the rotator cuff deficient shoulder.

The rotator cuff is often severely damaged in arthritis of the shoulder and there is no satisfactory technique for its repair. patients with a ruptured cuff and an eroded glenohumeral joint may have intractable pain, and standard methods of joint replacement are then inappropriate. A ball and socket prosthesis has been designed to replace the function of both the rotator cuff and the glenohumeral joint. Mechanical testing has shown that the scapular cup can be securely fixed. The outcome in 71 shoulders operated upon since 1973 is reported.

Mode of failure for rotator cuff repair with suture anchors identified at revision surgery.

Rotator cuff tears are a common cause of shoulder pain and dysfunction. After surgical repair, there is a significant re-tear rate (25%-90%). The aim of this study was to determine the primary mode of mechanical failure for rotator cuffs repaired with suture anchors at the time of revision rotator cuff repair. We prospectively followed 342 consecutive torn rotator cuffs, repaired by a single surgeon using suture anchors and a mattress-suturing configuration. Of those shoulders, 21 (6%) subsequently underwent a revision rotator cuff repair by the original surgeon, and 1 underwent a second revision repair. Intraoperative findings, including the mode of failure, were systematically recorded at revision surgery and compared with the findings at the primary repair. In addition, 81 primary rotator cuff repairs had a radiographic and fluoroscopic evaluation at a mean of 37 weeks after repair to assess for any loosening or migration of the anchors. At revision rotator cuff repair, the predominant mode of failure was tendon pulling through sutures (19/22 shoulders) (P <.001). Two recurrent tears occurred in a new location adjacent to the previous repair, and one anchor was found loose in the supraspinatus tendon. The mean size of the rotator cuff tear was larger at the revision surgery (P =.043), the tendon quality ranked poorer (P =.013), and the tendon mobility decreased (P =.002), as compared with the index procedure. The radiographs and fluoroscopic examination showed that all 335 anchors in 81 patients were in bone. Rotator cuff repairs with suture anchors that underwent revision surgery failed mechanically by three mechanisms, the most common of which was tendon pulling through sutures. This suggests that the weak link in rotator cuff repairs with suture anchors and horizontal mattress sutures, as determined at revision surgery, is the tendon-suture interface.

Latissimus dorsi transfer for the treatment of irreparable tears of the rotator cuff.

Sixteen irreparable, massive rotator cuff tears were treated with latissimus dorsi transfer and reviewed after an average of 33 months. There were no neurovascular complications or infections. Pain relief was satisfactory in 94% of the shoulders at rest and in 81% on exertion. Flexion was 83 degrees preoperatively and 135 degrees postoperatively. The functional value of the shoulder averaged 73% of an age- and gender-adjusted normal score. For the 12 shoulders with a functional subscapularis, it averaged 82%; for those four without a functioning subscapularis, 48%. If the subscapularis was torn and could not be adequately repaired, latissimus dorsi transfer was of no value. In cases with good subscapularis function but irreparable defects in the external rotator tendons, restoration of approximately 80% of normal shoulder function was obtained, indicating that latissimus dorsi transfer is a safe and valuable alternative for the treatment of this specific type of irreparable rotator cuff tear.

A biomechanical evaluation of suture anchors in repair of the rotator cuff.

Repair of the rotator cuff requires secure reattachment, but large chronic defects cause osteoporosis of the greater tuberosity which may then have insufficient strength to allow proper fixation of the tendon. Recently, suture anchors have been introduced, but have not been fully evaluated. We have investigated the strength of suture-to-anchor attachment, and the use of suture anchors in repairs of the rotator cuff either to the greater tuberosity or the lateral cortex of the humerus. The second method gave a significant increase in the strength of the repair (p = 0.014). The repairs were loaded cyclically and failed at low loads by cutting into bone and tendon, casting doubt on the integrity of the repair in early mobilisation after surgery. Repairs with suture anchors did not perform better than those with conventional transosseous attachment.

[Pathogenesis of ruptures of the shoulder rotator cuff].

Rupture of the rotator cuff occurs exceptionally in a healthy cuff and almost always in a degenerated cuff. This degeneration may be either ischaemic and secondarily conflictual or primarily conflictual. There are two zones of conflict: anteromedial and superior, resulting in two clinical presentations: small anterosuperior ruptures which are initially very painful, but minimally disabling and large posterosuperior ruptures which are initially which are immediately disabling but minimally painful.

Interventions for tears of the rotator cuff in adults.

BACKGROUND: Tears of the rotator cuff tendons, which surround the joints of the shoulder, are one of the most common causes of pain and disability in the upper extremity. OBJECTIVES: To review the efficacy and safety of common interventions for tears of the rotator cuff in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised trail register (July 2002), the Cochrane Controlled Trials Register (The Cochrane Library issue 2, 2002), MEDLINE (1966 to December 2001), EMBASE (1974 to December 2001), Biological Abstracts (1980 to December 2001), LILACS (1982 to December 2001), CINAHL (November 1982 to December 2001), Science Citation Index and reference lists of articles. We also contacted authors and handsearched conference proceedings focusing on shoulder conditions. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials involving tears of the rotator cuff were the focus of this review. All trials involving conservative interventions or surgery were included (non-steroidal anti-inflammatory drugs, intra-articular or subacromial glucocorticosteroid injection, oral glucocorticosteroid treatment, physiotherapy, and open or arthroscopic surgery). DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed suitability for inclusion, methodological quality and extracted data. Dichotomous data were presented as relative risks (RR) and 95% confidence intervals (CI), using the fixed effects model. MAIN RESULTS: Eight trials involving 455 people were included and 393 patients analysed. Trials were grouped in eight categories of conservative or surgical treatment. The median quality score of all trials combined was 16 out of a possible 24 points, with a range of 12-18. In general, included trials differed on diagnostic criteria for rotator cuff tear, there was no uniformity in reported outcome measures, and data which could be summarised were rarely reported. Only results from two studies comparing open repair to arthroscopic debridement could be pooled. There is weak evidence for the superiority of open repair of rotator cuff tears compared with arthroscopic debridement. REVIEWER'S CONCLUSIONS: There is little evidence to support or refute the efficacy of common interventions for tears of rotator cuff in adults. As well as the need for further well designed clinical trials, uniform methods of defining interventions for rotator cuff tears and validated outcome measures are also essential.

Rotator cuff disease. An arthroscopic view.

Rotator cuff disease has become a treatable entity by using the arthroscope; however, a sound understanding of pathology and an appreciation of relevant physical findings are necessary if the arthroscope is to be used effectively. Arthroscopic examination confirms the extent of rotator cuff disease and co-morbid pathology and allows for treatment of many problems related to the rotator cuff.

Mini-open rotator cuff repair: an updated perspective.

The mini-open rotator cuff or arthroscopically assisted surgical procedure for repair of the rotator cuff has become a popular procedure with proven clinical results. The development of this procedure has followed a natural progression toward more minimally invasive means to accomplish rotator cuff repair. For many, it represents a middle ground between the traditional formal open repair and the newer complete arthroscopic rotator cuff repairs. As arthroscopic rotator cuff repair becomes more refined and accepted, the mini-open repair can also represent an excellent transitional technique to someday accomplish the more technically difficult complete arthroscopic repair. Whether used as the definitive rotator cuff repair procedure or as a transitional procedure toward arthroscopic repair, the mini-open repair can be thought of as two different types of procedures, an arthroscopically assisted open repair in which the actual repair is performed in a primarily open fashion, or as a mini-open assisted arthroscopic repair in which most of the repair is performed arthroscopically and an open exposure provided just for bone-tendon fixation. With either strategy, the mini-open repair represents an excellent technique for treating full-thickness rotator cuff tears and offers many of the advantages of either formal or complete arthroscopic repair while minimizing many of the disadvantages.

The relative importance of acromial morphology and age with respect to rotator cuff pathology.

The purpose of this study was to examine the relationship between patient age, acromial morphology, and rotator cuff pathology. Data on 523 patients who had arthroscopic and/or open shoulder surgery were reviewed. Acromial morphology was classified by the system of Bigliani. All patients were categorized by postoperative diagnosis as having tendinitis of the rotator cuff, partial rotator cuff tear, complete rotator cuff tear, and non-rotator cuff-related pathology. Univariate analysis results for acromial morphology (P <.001), age (P <.001), and gender (P =.019) showed a significant association with rotator cuff pathology. Fifty percent of patients with rotator cuff tendinitis had type I acromions, and 58% of patients with full-thickness rotator cuff tears had type III acromions. Stratified univariate analysis revealed no significant association between acromial morphology and rotator cuff pathology in patients who were over 50 years old. Patients with full-thickness rotator cuff tears were significantly older than those with partial-thickness tears or tendinitis. A larger proportion of male patients than female patients had full-thickness rotator cuff tears. Multivariable logistic regression analysis identified acromial morphology, age, and gender as independent multivariate predictors of rotator cuff pathology. Age, acromial morphology, and gender all have an independent association with rotator cuff pathology.

The results of repair of massive tears of the rotator cuff.

BACKGROUND: Massive tears of the tendons of the rotator cuff cause atrophy and fatty degeneration of the rotator cuff muscles and painful loss of function of the shoulder. Repair of massive rotator cuff tears is often followed by retears of the tendons, additional muscular degeneration, and a poor clinical outcome. The purposes of this study were to determine whether a new method of repair of rotator cuff tendons can yield a lower retear rate and a better clinical outcome than previously reported methods, to assess the muscular changes following repair of massive tears of the musculotendinous units, and to correlate findings on magnetic resonance imaging with the clinical results. METHODS: Twenty-nine massive rotator cuff tears involving complete detachment of at least two tendons were repaired operatively with use of a new laboratory-tested technique in a prospective study. At least two years (average, thirty-seven months; range, twenty-four to sixty-one months) postoperatively, twenty-seven patients were evaluated clinically and with magnetic resonance imaging to determine the clinical outcome, the integrity of the repair, and the condition of the rotator cuff muscles. RESULTS: The age and gender-adjusted Constant score improved from an average of 49 percent preoperatively to an average of 85 percent postoperatively, corresponding to a subjective shoulder value of 78 percent of that of a normal shoulder. Pain-free flexion improved from an average of 92 degrees to an average of 142 degrees, and abduction improved from an average of 82 degrees to an average of 137 degrees. Pain decreased and performance of activities of daily living improved significantly (p < 0.05). The seventeen patients who had a structurally successful repair all had an excellent clinical outcome. Muscle atrophy could not be reversed except in successfully repaired supraspinatus musculotendinous units. Fatty degeneration increased in all muscles. CONCLUSIONS: The method of repair of massive rotator cuff tears that was used in this study yielded a comparatively low retear rate and good-to-excellent clinical results; however, the repair did not result in substantial reversal of muscular atrophy and fatty degeneration. Retears occurred more often in patients who had had a shorter interval between the onset of the symptoms and the operation (p < 0.05). Patients who had a retear had improvement of the shoulder compared with the preoperative state, but they had less improvement than did those who had a successful repair.
