Abstract
Although the teres minor is often overlooked in a normal shoulder, it becomes a key component in maintaining shoulder function when other rotator cuff tendons fail. The teres minor maintains a balanced glenohumeral joint and changes from an insignificant to the most significant external rotator in the presence of major rotator cuff pathology. The presence or absence of the teres minor provides prognostic information on the outcomes of reverse total shoulder arthroplasty and tendon transfers. Clinical tests include the Patte test, the Neer dropping sign, the external rotation lag sign, and the Hertel drop sign. Advanced imaging of the teres minor can be used for classification using the Walch system. Understanding the function and pathology surrounding the teres minor is paramount in comprehensive management of the patient with shoulder pathology. Appropriate clinical examination and imaging of the teres minor are important for preoperative stratification and postoperative expectations.

J Shoulder Elbow Surg 2018; 27:499-509. [PMID: 29290606 DOI: 10.1016/j.jse.2017.07.008] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Revised: 07/12/2017] [Accepted: 07/14/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND The purpose of this study was to characterize a subgroup of cuff-deficient patients with isolated loss of active external rotation (ILER) but preserved active elevation and to evaluate the outcomes of the L'Episcopo procedure to restore horizontal muscle balance. METHODS During a 10-year period, 26 patients (14 men, 12 women) were identified with ILER in the setting of massive irreparable posterosuperior cuff tears. A modified L'Episcopo tendon transfer was performed to restore active external rotation and to improve shoulder function. The mean age at surgery was 64.5 years (29-83 years). Patients were evaluated with a mean follow-up of 52 months (range, 24-104 months). RESULTS Preoperatively, despite maintained active elevation (average of 161°), ILER patients complained about loss of spatial control of the arm and difficulties with activities of daily living. On computed tomography scan or magnetic resonance imaging, there was severe fatty infiltration of infraspinatus and absent or atrophic teres minor. After L'Episcopo transfer, 84% of patients were satisfied. The gain in active external rotation was +26° in arm at the side and +18.5° in 90° abduction. Adjusted Constant score and Simple Shoulder Value increased from 63.6% to 86.9% and from 36.9% to 70.8%, respectively (P < .001). The ADLER score increased from 10 to 24.5 points (P < .002). Two patients with advanced cuff tear arthropathy (Hamada stage 3 and 4) required conversion to a reverse shoulder arthroplasty (RSA) 7 and 9 years after the index surgery. CONCLUSIONS ILER is a distinct entity that is a cause of severe handicap because of loss of spatial control of the upper limb. This symptom is related to absent or atrophied infraspinatus and teres minor. In properly selected cases (Hamada stage 1 or 2), the modified L'Episcopo transfer is effective at restoring anterior-posterior rotator cuff force balance. In more advanced cuff tear arthropathy (Hamada stage ≥3), the tendon transfer should be performed with an RSA because of possible secondary degeneration of the glenohumeral joint.

Abstract
PURPOSE OF REVIEW This review aims to describe the tendon transfer options for treating irreparable rotator cuff tears (RCTs). Options for transfer include latissimus dorsi and lower trapezius transfers for posterior-superior RCTs and pectoralis major and latissimus dorsi transfer for anterior-superior RCTs. RECENT FINDINGS While the latissimus dorsi tendon transfer has historically been performed for posterosuperior RCTs, the lower trapezius transfer is a more anatomic option and has demonstrated promising results in recent studies. Similarly, the pectoralis major transfer has historically been the tendon transfer of choice for anterosuperior RCTs. However, the latissimus dorsi tendon transfer has recently been shown to be a safe and anatomic tendon transfer for subscapularis insufficiency. The treatment of irreparable RCTs involves complex decision making. Tendon transfer procedures can restore the glenohumeral joint force couples, allowing restoration of near-normal shoulder kinematics. Benefits include reliable pain relief, increased function, and increased strength. Proper selection of donor tendon is crucial, and the principles of tendon transfer procedures must be adhered to for maximal benefit.

Abstract
BACKGROUND The teres minor muscle is a focused topic on the treatment of massive rotator cuff tears and reverse total shoulder arthroplasty. Its precise anatomy and function have not been completely investigated. The purposes of this study were to anatomically investigate the muscle and analyze electromyographic (EMG) activities during shoulder motion. METHODS This anatomic study used 20 shoulders from deceased donors (mean age, 75.0 years). EMG data were recorded from 10 healthy volunteers (mean age, 21.7 years) during flexion, abduction, and external rotations at 0° of abduction, at 90° of abduction, and at 90° of flexion in their dominant arms synchronized with a computerized 3-dimensional motion analysis system. RESULTS The muscle in all specimens consisted of 2 distinct muscular bundles: the upper and lower portions. The upper portion attached to the round area of the greater tuberosity, and the lower portion inserted into the linear shaped area. Both portions were independent in their origins, insertions, and innervation. The muscle engaged force during each shoulder motion. EMG activities of abduction and the 3 forms of external rotation were similar. Maximal voluntary contraction in the 3 forms of external rotation was 32% in maximum external rotation in the neutral position, 25% in flexion, and 40% in abduction. CONCLUSIONS The teres minor consists of independent upper and lower portions. The muscle engages force in all ranges of 5 shoulder motions, and maximum external rotation in abduction is a reliable method to evaluate potential activity of the muscle.

Abstract
BACKGROUND Massive rotator cuff tears pose a difficult and complex challenge even for the experienced surgeon; inability to repair these tears by conventional means designates them as irreparable, while management becomes quite taxing. Several operative options have been suggested for the management of such lesions with varying degrees of success, while it is imperative to match patient demands and expectations to the predicted outcome. METHODS Research articles are examined and key concepts are discussed, in order to provide an evidence based review of the available literature. The anatomy and pathomechanics along with the indications, contraindications and surgical techniques are reported. RESULTS Transfer of the Latissimus dorsi has been used with success to restore shoulder function in deficits of the posterior rotator cuff. Although it can be used in a variety of settings, the ideal patient for a Latissimus dorsi tendon transfer is a young and active individual, with no glenohumeral osteoarthritis that has a severe disability and weakness related to an irreparable posterior cuff tear. CONCLUSION Tendon transfers have proved to be a successful treatment option in salvaging this difficult problem, providing pain relief and restoring shoulder function. Despite the excellent functional outcomes and pain suppression following operation, a variety of factors may affect the outcome; thus making indications and preoperative assessment a valuable component.

Abstract
BACKGROUND In posterosuperior rotator cuff tears (PS-RCT), the progression of infraspinatus (ISP) muscle atrophy seems to induce compensatory hypertrophy of the teres minor (TM) muscles. However, the effect of these changes on shoulder strength and range of external rotation (ER) remains unclear. This study determined the strength and range of ER in patients with PS-RCT with atrophic ISP and hypertrophic TM and compared this with patients with PS-RCT and normal or deficient TM. METHODS We investigated 35 patients with PS-RCT and atrophic ISP. TM muscles were classified as hypertrophic (type A) in 17, normal (type B) in 10, or deficient (type C) in 8. The strength ratio of the affected shoulder to the healthy contralateral shoulder was calculated, and the active range of motion was measured for both shoulders. RESULTS The strength ratios of ER in types A, B, and C were 60%, 33%, and 7% (P < .01) with the patient's arm at the side and were 60%, 35%, and 5% (P < .001) at 90° abduction, respectively. The average ranges of ER in types A, B, and C were 22.6°, 15.0°, and -12.5° (P < .001) with the patient's arm at the side and were 71.6°, 44.5°, and 21.9° at 90° abduction (P < .01), respectively. The differences between shoulder types in other measures of strength or ER range were not significant. CONCLUSIONS In patients with PS-RCT and atrophic ISP, shoulders with compensatory hypertrophy of the TM had greater strength and range of ER than shoulders with normal or atrophic TM.

Abstract
BACKGROUND Management of massive irreparable posterior-superior rotator cuff tear can be very challenging. This study reports the outcome of the lower trapezius transfer to reconstruct massive irreparable posterior-superior rotator cuff tear. METHODS Included were 33 patients with an average age of 53 years (range, 31-66 years). All patients had symptomatic massive irreparable rotator cuff tear that failed conservative or prior surgical treatment and underwent reconstruction with lower trapezius transfer prolonged by Achilles tendon allograft. The tear was considered irreparable based on the magnetic resonance imaging finding of ≥2 full-thickness rotator cuff tears associated with shortening and retraction of the tendon to the level of the glenoid and a high grade of fatty infiltration of the muscles. This was confirmed at the time of the surgery. RESULTS At an average follow-up of 47 months, 32 patients had significant improvement in pain, subjective shoulder value, and Disabilities of the Arm, Shoulder and Hand score and shoulder range of motion, including flexion, 120°; abduction, 90°; and external rotation 50°. One patient, with a body mass index of 36 kg/m(2), required débridement for an infection and then later underwent shoulder fusion. Patients with >60° of preoperative flexion had more significant gains in their range of motion. Shoulder external rotation improved in all patients regardless of the extent of the preoperative loss of motion. CONCLUSIONS Transfer of the lower trapezius prolonged with Achilles tendon allograft to reconstruct massive irreparable posterior-superior rotator cuff tear may lead to good outcome in most patients, specifically for those who have preoperative flexion of >60°.

Abstract
Background: Tendon transfers can be a surgical treatment option in managing younger, active patients with massive irreparable rotator cuff tears. The purpose of this article is to provide an overview of the use of tendon transfers to treat massive irreparable rotator cuff tears and to summarize clinical outcomes. Methods: A selective literature search was performed and personal surgical experiences are reported. Results: Latissimus dorsi transfers have been used for many years in the management of posterosuperior rotator cuff tears with good reported clinical outcomes. It can be transferred without or with the teres major (L’Episcopo technique). Many surgical techniques have been described for latissimus dorsi transfer including single incision, double incision, and arthroscopically assisted transfer. Transfer of the pectoralis major tendon is the most common tendon transfer procedure performed for anterosuperior rotator cuff deficiencies. Several surgical techniques have been described, however transfer of the pectoralis major beneath the coracoid process has been found to most closely replicate the force vector that is normally provided by the intact subscapularis. Conclusion: Tendon transfers can be used successfully in the management of younger patients with massive irreparable rotator cuff tears and minimal glenohumeral arthritis. Improvements in clinical outcomes scores and range of motion have been demonstrated. This can delay arthroplasty, which is of particular importance for younger patients with high functional demands.

Abstract
Despite the high level achieved in the field of shoulder surgery, a global consensus on rotator cuff tears management is lacking. This work is divided into two main sessions: in the first, we set questions about hot topics involved in the rotator cuff tears, from the etiopathogenesis to the surgical treatment. In the second, we answered these questions by mentioning Evidence Based Medicine. The aim of the present work is to provide easily accessible guidelines: they could be considered as recommendations for a good clinical practice developed through a process of systematic review of the literature and expert opinion, in order to improve the quality of care and rationalize the use of resources.

Compensatory hypertrophy of the teres minor muscle after large rotator cuff tear model in adult male rat. J Shoulder Elbow Surg 2016; 25:316-21.

Abstract
BACKGROUND Rotator cuff tear (RCT) is a common musculoskeletal disorder in the elderly. The large RCT is often irreparable due to the retraction and degeneration of the rotator cuff muscle. The integrity of the teres minor (TM) muscle is thought to affect postoperative functional recovery in some surgical treatments. Hypertrophy of the TM is found in some patients with large RCTs; however, the process underlying this hypertrophy is still unclear. The objective of this study was to determine if compensatory hypertrophy of the TM muscle occurs in a large RCT rat model. METHODS Twelve Wistar rats underwent transection of the suprascapular nerve and the supraspinatus and infraspinatus tendons in the left shoulder. The rats were euthanized 4 weeks after the surgery, and the cuff muscles were collected and weighed. The cross-sectional area and the involvement of Akt/mammalian target of rapamycin (mTOR) signaling were examined in the remaining TM muscle. RESULTS The weight and cross-sectional area of the TM muscle was higher in the operated-on side than in the control side. The phosphorylated Akt/Akt protein ratio was not significantly different between these sides. The phosphorylated-mTOR/mTOR protein ratio was significantly higher on the operated-on side. CONCLUSION Transection of the suprascapular nerve and the supraspinatus and infraspinatus tendons activates mTOR signaling in the TM muscle, which results in muscle hypertrophy. The Akt-signaling pathway may not be involved in this process. Nevertheless, activation of mTOR signaling in the TM muscle after RCT may be an effective therapeutic target of a large RCT.

Abstract
Shoulder dysfunction in the setting of irreparable rotator cuff tears (RCTs) can be treated successfully with different types of tendon transfer: Latissimus dorsi transfer for irreparable posterosuperior RCTs works best for young, active patients with an intact subscapularis, no pseudoparalysis or previous surgery, and a functioning teres minor.A more anatomical transfer for irreparable posterosuperior RCTs is a lower trapezius transfer, and early results are promising.Isolated irreparable tears of the subscapularis can be successfully managed with pectoralis major tendon transfer with a concentric humeral head. However, restricted external rotation (ER) may occur, depending on technique.Pectoralis minor transfer can successfully address combination irreparable tears of the upper border subscapularis and the supraspinatus without significant loss of ER.Rotator cuff arthropathy with ER lag benefits most from a reverse total shoulder arthroplasty and a combination latissimus dorsi and teres major transfer (LDTMT) regardless of patient age.

BACKGROUND Combined single-stage reverse total shoulder arthroplasty (RTSA) plus latissimus dorsi transfer (LDT) has been reported to be a reliable treatment for pseudoparalysis of elevation and external rotation caused by irreparable rotator cuff tears. Secondary LDT in patients with pseudoparalysis of external rotation after previous RTSA has not yet been studied. METHODS Ten patients were treated with LDT at a mean of 27 months (range, 4-134 months) after RTSA. Standard LDT was performed in 4 patients and a LDT plus teres major transfer according to L'Episcopo in 6 patients. All patients had preoperative and postoperative clinical evaluation, including the assessment of the Constant score and the subjective shoulder value. RESULTS RTSA increased the preoperative mean relative Constant score from 26% (range, 11%-67%) to 51% (range, 20%-100%; P = .05). At a mean of 49 months (range, 23-67 months) after additional LDT, the relative Constant score further increased to 58% (range, 34%-100%; P = .141), remaining significantly superior to the score before RTSA (P = .021). The mean subjective shoulder value was 15% (range, 0%-30%) before and 44% (range, 20%-70%) after RTSA (P = .273) and was 56% (range, 20%-90%) after LDT (P = .686), a significant overall improvement of the state of the shoulder compared with before RTSA (P = .042). Mean active flexion increased from 36° (range, 0°-130°) to 86° (range, 10°-140°) after RTSA (P = .024) and to 109° (range,70°-140°) after LDT (P = 0.017 compared with pre-LDT; P = .011 compared with pre-RTSA). Mean active external rotation decreased from 0° (range, -80° to 50)° to -18° (range, -50°to 10)° after RTSA (P = .079) and was improved to 2° (-40° to 40)° after LDT (P = .24 compared with pre-LDT; P=.865 compared with pre RTSA). CONCLUSION Secondary LDT significantly improves active mobility in patients with residual dysfunction after RTSA.

Abstract
Rotator cuff tears (RCTs) occur more commonly with advanced age, with most rotator cuff abnormalities in patients less than 30 years old being painful tendinoses or partial-thickness RCTs. Irreparable postero-superior cuff tears has been reported as frequent as 7% to 10% in the general population, and the incidence of irreparable RCTs in young patients is still unknown. Several surgical procedures have been proposed for young patients with irreparable postero-superior RCTs, such as rotator cuff debridement, partial rotator cuff repair, biceps tenotomy/tenodesis, rotator cuff grafting, latissimus dorsi tendon transfer, and reverse shoulder arthroplasty. After being thoroughly investigated in open surgery, arthroscopic techniques for latissimus dorsi tendon transfer have been recently described. They have been shown to be an adequate option to open surgery for managing irreparable postero-superior RCTs refractory to conservative management.

Abstract
Rotator cuff tear size has an important effect on clinical outcomes after repair. Management options for massive rotator cuff tears are numerous, and selection of the most appropriate treatment method for individual patients can be a challenge. An understanding of the pathomechanics, treatment, and clinical outcomes in patients with massive rotator cuff tears can serve as a guide for clinical decision-making. The purpose of this article was to review treatment options and clinical outcomes for the management of massive rotator cuff tears.

Abstract
BACKGROUND Few studies define the clinical signs to evaluate the integrity of teres minor in patients with massive rotator cuff tears. CT and MRI, with or without an arthrogram, can be limited by image quality, soft tissue density, motion artifact, and interobserver reliability. Additionally, the ill-defined junction between the infraspinatus and teres minor and the larger muscle-to-tendon ratio of the teres minor can contribute to error. Therefore, we wished to determine the validity of clinical testing for teres minor tears. QUESTION/PURPOSES The aim of this study was to determine the accuracy of commonly used clinical signs (external rotation lag sign, drop sign, and the Patte test) for diagnosing the teres minor's integrity. METHODS We performed a prospective evaluation of patients referred to our shoulder clinic for massive rotator cuff tears determined by CT arthrograms. The posterosuperior rotator cuff was examined clinically and correlated with CT arthrograms. We assessed interobserver reliability for CT assessment and used three different clinical tests of teres minor function (the external rotation lag sign, drop sign, and the Patte test). One hundred patients with a mean age of 68 years were available for the analysis. RESULTS The most accurate test for teres minor dysfunction was an external rotation lag sign greater than 40°, which had a sensitivity of 100% (95% CI, 80%-100%) and a specificity of 92% (95% CI, 84%-96%). External rotation lag signs greater than 10° had a sensitivity of 100% (95% CI, 80%-100%) and a specificity of 51% (95% CI, 40%-61%). The Patte sign had a sensitivity of 93% (95% CI, 70%-99%) and a specificity of 72% (95% CI, 61%-80%). The drop sign had a sensitivity of 87% (95% CI, 62%-96%) and a specificity of 88% (95% CI, 80%-93%). An external rotation lag sign greater than 40° was more specific than an external rotation lag sign greater than 10° (p < 0.001), and a Patte sign (p < 0.001), but was not more specific than the drop sign (p < 0.47). There was poor correlation between involvement of the teres minor and loss of active external rotation. CONCLUSIONS Clinical signs can predict anatomic patterns of teres minor dysfunction with good accuracy in patients with massive rotator cuff tears. This study showed that the most accurate test for teres minor dysfunction is an external rotation lag sign and that most patients' posterior rotator cuff tears do not lose active external rotation. Because imaging is not always accurate, examination for integrity of the teres minor is important because it may be one of the most important variables affecting the outcome of reverse shoulder arthroplasty for massive rotator cuff tears, and the functional effects of tears in this muscle on day to day activities can be significant. Additionally, teres minor integrity affects the outcomes of tendon transfers, therefore knowledge of its condition is important in planning repairs. LEVEL OF EVIDENCE Level III, diagnostic study.

Abstract
BACKGROUND Arthroscopic partial repair is a treatment option in irreparable large-to-massive rotator cuff tears without arthritic changes. However, there are indications that arthroscopic partial repair does not yield satisfactory outcomes. PURPOSE To report the clinical and radiographic results of arthroscopic partial repairs in patients with irreparable large-to-massive cuff tears. In addition, an analysis was performed regarding preoperative factors that may influence patient outcomes and patient-rated satisfaction over time. STUDY DESIGN Case series; Level of evidence, 4. METHODS From 2005 to 2011, a total of 31 patients who underwent arthroscopic partial repair for irreparable large-to-massive cuff tears were retrospectively evaluated. Partial repair was defined as posterior cuff tissue repair with or without subscapularis tendon repair to restore the transverse force couple of the cuff. Pain visual analog scale (PVAS), questionnaire results (American Shoulder and Elbow Surgeons [ASES] and Simple Shoulder Test [SST]), and radiographic changes (acromiohumeral distance and degenerative change) were assessed preoperatively, at first follow-up (roughly 1 year postoperatively), and at final follow-up (>2 years postoperatively). Patients rated their satisfaction level at each postoperative follow-up as well. Preoperative factors that might influence outcomes, such as patient demographics, tear size, and fatty infiltration, were investigated. RESULTS The preoperative, first follow-up, and final follow-up results for mean PVAS (5.13, 2.13, and 3.16, respectively) and questionnaires (ASES: 41.97, 76.37, and 73.78; SST: 3.61, 6.33, and 6.07, respectively) improved significantly (all P < .05). Radiographic evaluation showed no difference compared with preoperative status. Nevertheless, patient-rated satisfaction at final evaluation was inferior: 16 good responses ("very satisfied" and "satisfied") and 15 poor responses ("rather the same" and "dissatisfied"). Despite initial improvements in both groups (P < .05), patients with poor satisfaction demonstrated statistically significant deterioration in mean PVAS (from 2.07 to 4.67), questionnaire scores (ASES: from 74.56 to 59.80; SST: from 5.11 to 3.81), and acromiohumeral distance (from 7.19 to 5.06 mm) between the first and final follow-up (all P < .05). Patients with good satisfaction showed no significant difference or they improved (P > .05) from the first to the final follow-up. Among preoperative factors, fatty infiltration of the teres minor was identified as the only statistically significant factor affecting patient-rated satisfaction (P = .007). CONCLUSION This study showed that arthroscopic partial repair may produce initial improvement in selected outcomes at 2-year follow-up. However, about half of the patients in the study were not satisfied with their outcomes, which had deteriorated over time. Preoperative fatty infiltration of the teres minor was the only factor that correlated with worse final outcomes and poor satisfaction after arthroscopic partial repair.

Abstract
PURPOSE To evaluate, in a multicenter, prospective study, the clinical, magnetic resonance imaging (MRI), and radiologic results of arthroscopic-assisted latissimus dorsi (LD) tendon transfer for irreparable posterosuperior rotator cuff tears; and to assess the influence of perioperative data on clinical results. METHODS Fifty-five patients with irreparable tears of at least the supraspinatus and infraspinatus tendons were managed with arthroscopic-assisted LD tendon transfer and reviewed clinically, with standardized radiographs and MRI, after a mean of 29 months. Outcome measures included the Constant score and the Subjective Shoulder Value. The osteoarthritic stage and acromiohumeral distance were measured on standardized radiographs, and the transferred tendon aspect was evaluated on MRI. RESULTS Thirty patients had already undergone 1 or more previous surgical procedures. The mean Subjective Shoulder Value increased from 26% preoperatively to 71% postoperatively. The Constant score improved from 37 preoperatively to 65.4 postoperatively. The pain score increased from 1.7 preoperatively to 12.6 postoperatively; the activity score, from 6.4 to 13.8; active forward flexion, from 134° to 157°; active abduction, from 67° to 92.5°; active external rotation, from 29° to 41.5°; and abduction strength, from 1.4 kg to 4.8 kg. The only statistically significant factor negatively influencing the Constant score was previous surgery. Four patients had a ruptured LD tendon on MRI follow-up at 1 year. There was no statistical difference between preoperative and final follow-up acromiohumeral distance. There was no increase in osteoarthritic stage. CONCLUSIONS Arthroscopic-assisted LD tendon transfer improves shoulder pain and function in patients with irreparable posterosuperior cuff tears, with similar clinical and radiologic results compared with results of published series using open techniques. Patients with a history of surgery had lower Constant scores compared with non-previously operated patients. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Every year approximately 18 million Americans report shoulder pain, a large percentage of which are a result of rotator cuff disease. Rotator cuff tear progression can be difficult to predict. Factors associated with tear enlargement include increasing symptoms, advanced age, involvement of 2 or more tendons, and rotator cable lesion. Nonsurgical treatment can be effective for patients with full-thickness tears. When conservative treatment fails, surgical repair provides a reliable treatment alternative. Recurrent tears after surgery can compromise outcomes, particularly for younger patients with physically demanding occupations. Revision surgery provides satisfactory results for those with symptomatic re-tears. If the tear is deemed irreparable, addressing concomitant biceps pathology or performing partial repairs can reliably improve pain and potentially reverse pseudoparalysis. The reverse shoulder arthroplasty has limited indications in the setting of rotator cuff tears and should be reserved for patients with painful pseudoparalysis and associated arthropathy.

Abstract
BACKGROUND Few reports have assessed the teres minor (TM) muscle in rotator cuff tears. This study aimed to quantitatively analyze the morphologic changes of the TM muscle in patients with or without rotator cuff tears by magnetic resonance imaging (MRI). METHODS This retrospective study consisted of 279 subjects classified on the basis of interpretations of conventional MRI observations into 6 groups: no cuff tear; partial-thickness supraspinatus (SSP) tear; full-thickness SSP tear; SSP and subscapularis tears; SSP and infraspinatus (ISP) tears; and SSP, ISP, and subscapularis tears. With use of ImageJ software (National Institutes of Health, Bethesda, MD, USA) for oblique sagittal MRI, we measured the areas of ISP, TM, and anatomic external rotation (ISP + TM) muscles on the most lateral side in which the scapular spine was in contact with the scapular body. The occupational ratios of the TM muscle area to the anatomic external rotation muscle area were calculated. Ratios above the maximum of the 95% confidence intervals of the occupational ratio in the no-tear group were defined as hypertrophy of the TM muscle. RESULTS Occupational ratios of the TM muscle in the no-tear group followed a normal distribution, and ratios >0.288 were defined as hypertrophic. Hypertrophic changes of the TM muscle were confirmed in rotator cuff tears involving the ISP tendon. A negative correlation was found between the occupational ratios of TM and ISP (P < .001). CONCLUSION The TM muscle appeared hypertrophic in rotator cuff tears involving the ISP, and the progression of ISP muscle atrophy seemed to induce the development of this compensatory hypertrophy.

Abstract
BACKGROUND Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy. QUESTIONS/PURPOSES The purpose of this study was to determine whether the observed improvement in shoulder function in the early postoperative period with latissimus dorsi tendon transfer for irreparable rotator cuff tears will be permanent or will deteriorate in the midterm period (at 1-5 years after surgery). METHODS During a 6-year period, we performed 11 latissimus dorsi tendon transfers in 11 patients for patients with massive, irreparable, chronic tears of the posterosuperior part of the rotator cuff (defined as > 5 cm supraspinatus and infraspinatus tendon tears with Goutallier Grade 3 to 4 fatty infiltration on MRI), for patients who were younger than 65 years of age, and had high functional demands and intact subscapularis function. No patients were lost to followup; minimum followup was 12 months (median, 33 months; range, 12-62 months). The mean patient age was 55 years (median, 53 years; range, 47-65 years). Shoulder forward elevation, external rotation, and Constant-Murley and American Shoulder and Elbow Surgeons scores were assessed. Pain was assessed by a 0- to 10-point visual analog scale. Acromiohumeral distance and cuff tear arthropathy (staged according to the Hamada classification) were evaluated on radiographs. RESULTS Shoulder forward elevation, external rotation, Constant-Murley scores, and American Shoulder and Elbow Surgeons scores improved at 6 months. However, although shoulder motion values and Constant-Murley scores remained unchanged between the 6-month and latest evaluations, American Shoulder and Elbow Surgeons scores decreased in this period (median, 71; range, 33-88 versus median, 68; range, 33-85; p = 0.009). Visual analog scale scores improved between the preoperative and 6-month evaluations but then worsened (representing worse pain) between the 6-month and latest evaluations (median, 2; range, 0-5 versus median, 2; range, 1-6; p = 0.034), but scores at latest followup were still lower than preoperative values (median, 7; range, 4-8; p = 0.003). Although acromiohumeral distance values were increased at 6 months (median, 8 mm; range, 6-10 mm; p = 0.023), the values at latest followup (median, 8 mm; range, 5-10 mm) were no different from the preoperative ones (mean, 7 mm; range, 6-9 mm; p > 0.05). According to Hamada classification, all patients were Grade 1 both pre- and postoperatively, except one who was Grade 3 at latest followup. CONCLUSIONS The latissimus dorsi tendon transfer may improve shoulder function in irreparable massive rotator cuff tears. However, because the tenodesis effect loses its strength with time, progression of the arthropathy should be expected over time. Nevertheless, latissimus dorsi tendon transfer may help to delay the need for reverse shoulder arthroplasty for these patients. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Background This study examines the clinical and electromyographic results of latissimus dorsi transfer (LDT) using a combined open and arthroscopic technique for the treatment of symptomatic irreparable posterosuperior rotator cuff tears. Methods Between 2006 and 2009, LDT was performed in 14 patients (mean age 59 years) with massive and symptomatic irreparable posterosuperior rotator cuff tear. The patients were examined preoperatively and postoperatively with mean follow-up of 52 months using the Constant score, and the integrity of the latissimus dorsi (LD) transfer was assessed by ultrasound in all cases and by MRI in ten cases. The functional activity of the LD transfer was compared to the non-operated side using surface electromyography. Results All patients demonstrated a significant improvement in the Constant score (p = 0.001), from a preoperative score of 33 points (range 10–55 points) to a postoperative score of 59 points (range 13–80 points). The subjective assessment score was good to excellent in 12 patients (85%), and 11 patients (78%) would be willing to undergo surgery again. Integrity of the transferred tissue was confirmed in 13 of the 14 cases using ultrasound and MRI. Surface electromyographic signal showed increased activation of the transferred latissimus dorsi when performing active movements of external rotation (p = 0.002) and abduction-elevation (p = 0.009). Conclusions Our results indicate that LDT significantly improves function and diminishes pain in patients with a massive posterosuperior rotator cuff tear.

Abstract
Massive rotator cuff tears remain a complex and challenging problem for both the patient and the surgeon. Although significant advancements in surgical techniques as well as technology for arthroscopic and mini-open rotator cuff repairs have been made, many massive tears result in failed repair with continued progressive tendon retraction and degeneration. In cases when primary tendon to bone healing is impractical, latissimus dorsi tendon transfer provides promising and reproducible clinical results. Herein, we present a latissimus tendon transfer surgical technique, a procedure we have used as a salvage operation for failed arthroscopic/mini-open primary rotator cuff repair.

Electromyographic activity after latissimus dorsi transfer: testing of coactivation as a simple tool to assess latissimus dorsi motor learning. J Shoulder Elbow Surg 2014; 23:1162-70.

Abstract
BACKGROUND The purpose of this study was to investigate coactivation (CoA) testing as a clinical tool to monitor motor learning after latissimus dorsi tendon transfer. METHODS We evaluated 20 patients clinically with the American Shoulder and Elbow Surgeons (ASES) and University of California-Los Angeles (UCLA) outcomes scores, visual analog scale, active external rotation (aER), and isometric strength testing in abduction and external rotation. Measurements of aER were performed while the latissimus dorsi was activated in its new function of external rotation with concomitant activation (coactivation) of its native functions (adduction and extension). Bilateral surface electromyographic (EMG) activity was recorded during aER measurements and the strength testing procedure (EMG activity ratio: with/without CoA). Patients were divided into two groups (excellent/good vs fair/poor) according to the results of the ASES and UCLA scores. RESULTS The mean follow-up was 57.8 ± 25.2 months. Subdivided by clinical scores, the superior outcome group lost aER with CoA, whereas the inferior outcome group gained aER (UCLA score: -2.2° ± 7.4° vs +4.3° ± 4.1°; P = .031). Patients with inferior outcomes in the ASES score showed higher latissimus dorsi EMG activity ratios (P = .027), suggesting an inadequate motor learning process. Isometric strength testing revealed that the latissimus dorsi transfer had significantly greater activity compared with the contralateral side (external rotation, P = .008; abduction, P = .006) but did not have comparable strength (external rotation, P = .017; abduction, P = .009). CONCLUSIONS Patients with inferior clinical results were more likely to be dependent on CoA to gain external rotation. Therefore, CoA testing may be used as a tool to evaluate the status of postoperative motor learning after latissimus dorsi transfer.

Abstract
Latissimus dorsi tendon transfer is a method for surgical treatment of massive irreparable posterosuperior cuff tears. It partially restores active anteflexion, external rotation, and function of the shoulder but does not significantly increase strength of the shoulder. It is contraindicated in case of pseudoparalytic shoulder; associated irreparable subscapularis tear, deltoid palsy, and in case of associated osteoarthritis, as an isolated procedure. Results are inferior when performed as a secondary procedure compared with a primary procedure. However, latissimus dorsi tendon transfer is an attractive solution to improve shoulder mobility and function of young and non osteoarthritic patients whose previous surgical treatment of massive postero-superior irreparable rotator cuff tear failed. As a primary procedure, latissimus dorsi tendon transfer competes with debridement, biceps tenotomy, and partial cuff repair. In association with reverse shoulder arthroplasty, it restores active external rotation in osteoarthritic patients with active external rotation deficit. New arthroscopic assisted techniques might improve results in the future.

Abstract
BACKGROUND Reverse total shoulder arthroplasty (RTSA) allows correction of pseudoparesis of elevation caused by irreparable rotator cuff tear but does not address loss of active external rotation. Latissimus dorsi transfer (LDT) is an established procedure for correction of pseudoparesis of external rotation. METHODS Forty-one shoulders of 40 consecutive patients, who were a mean age of 70 years old (range 47-85 years), underwent RTSA combined with LDT for irreparable rotator cuff failure with severe shoulder dysfunction. RESULTS Nine orthopedic complications occurred in 7 of the 41 shoulders. Four shoulders were lost to follow-up, and 5 were excluded from the functional analysis. The mean follow-up of the eligible 32 shoulders with the prosthesis still in place was 53 months (range, 24-105 months). The age-related Constant score increased significantly from a preoperative mean of 45% (range, 16%-80%) to 89% (range, 25%-100%). The mean subjective shoulder value increased from 33% (range, 0%-70%) to 75% (range, 30%-100%). Active external rotation significantly improved from a mean of 4° (range, -30° to 40°) to 27° (range, -10° to 70°). A preoperative external rotation lag sign could be corrected in 25 of the 32 shoulders. For the 16 shoulders with at least 5 years of follow-up, the Constant scores were 47% (range, 16%-80%) preoperatively, 92% (range, 51%-100%) at 2 years, and 94% (range, 57%-100%) at the latest follow-up, and the respective subjective shoulder values were 32% (range, 0%-70%), 73% (range, 30%-100%), and 80% (range, 60%-100%). CONCLUSION If treated with RTSA combined with LDT, patients with pseudoparesis of elevation and pseudoparesis of external rotation can expect an excellent clinical outcome for a period beyond 5 years, provided that complications that require removal of the prosthesis can be prevented.

Abstract
BACKGROUND Transfer of the latissimus dorsi tendon to the greater tuberosity of the humerus for treatment of an irreparable rotator cuff tear has been reported to yield good-to-excellent short to intermediate-term results in well-selected patients. The purpose of this study was to evaluate the long-term outcome of such transfers for irreparable posterosuperior rotator cuff tears to determine the durability of the results and to identify risk factors for an unfavorable outcome. METHODS Fifty-seven shoulders in fifty-five patients (seventeen women and thirty-eight men with a mean age of fifty-six years) were managed with latissimus dorsi tendon transfer. Final follow-up was performed at a mean of 147 months. Outcome measures included the Constant score and the Subjective Shoulder Value (SSV). Osteoarthritis, the acromiohumeral distance, and the so-called critical shoulder angle were assessed on standardized radiographs. RESULTS Forty-six shoulders in forty-four patients were available at the time of final follow-up. The mean SSV increased from 29% preoperatively to 70% at the time of final follow-up, the relative Constant score improved from 56% to 80%, and the pain score improved from 7 to 13 points (p < 0.0001 for all). Mean flexion increased from 118° to 132°, abduction increased from 112° to 123°, and external rotation increased from 18° to 33°. Mean abduction strength increased from 1.2 to 2.0 kg (p = 0.001). There was a slight but significant increase in osteoarthritic changes. Inferior results occurred in shoulders with insufficiency of the subscapularis muscle and fatty infiltration of the teres minor muscle. Superior functional results were observed in shoulders with a small postoperative critical shoulder angle. CONCLUSIONS Latissimus dorsi tendon transfer offered an effective treatment for irreparable posterosuperior rotator cuff tears, with substantial and durable improvements in shoulder function and pain relief. Shoulders with fatty infiltration of the teres minor muscle and insufficiency of the subscapularis muscle tended to have inferior results, as did those with a large critical shoulder angle.

Abstract
PURPOSE Reverse shoulder arthroplasty (RSA) can restore active elevation in rotator-cuff-deficient shoulders. However, RSA cannot restore active external rotation. The combination of latissimus dorsi transfer with RSA has been reported to restore both active elevation and external rotation. We hypothesised that in the combined procedure, harvesting the latissimus dorsi with a small piece of bone, leads to good tendon integrity, low rupture rates and good clinical outcome. METHODS Between 2004 and 2010, 13 patients (13 shoulders) were treated with RSA in combination with latissimus dorsi transfer in a modified manner. The mean follow-up was 65.4 months, and the mean age at index surgery was 71.1 years. All patients had external rotation lag sign and positive hornblower's sign, as well as radiological signs of cuff-tear arthropathy (Hamada 3, 4 or 5) and fatty infiltration grade 3 according to Goutallier et al. on magnetic resonance imaging (MRI). The outcome measures included the Constant Murley Score, University of California-Los Angeles (UCLA) shoulder score, Simple Shoulder Test (SST), visual analogue scale (VAS) and the Activities of Daily Living Requiring External Rotation (ADLER) score. Tendon integrity was evaluated with dynamic ultrasound. All patients were asked at final follow-up to rate their satisfaction as excellent, good, satisfied or dissatisfied. RESULTS The overall mean Constant-Murley Shoulder Outcome Score (CMS) improved from 20.4 to 64.3 points (p < 0.001). Mean VAS pain score decreased from 6.8 to 1.1 (p < 0.001)., mean UCLA score improved from 7.9 to 26.4 (p < 0.001), mean SST score improved from 2.3 to 7.9 (p < 0.001) and mean postoperative ADLER score was 26 points. The average degree of abduction improved from 45° to 129° (p < 0.001), the average degree of anterior flexion improved from 55° to 138° (p < 0.001) and the average degree of external rotation improved from -16° to 21° (p < 0.001). Eight patients rated their results as very satisfied, three as satisfied and two as dissatisfied. CONCLUSION This modified technique, which avoids cutting the pectoralis major tendon and involves harvesting the tendon together with a small piece of bone, leads to good or even better functional results compared with the results reported in the literature, and also has high patient satisfaction and low failure rates.

Abstract
INTRODUCTION The present study reports the development of a CT assessment protocol for Teres Minor (TM) trophicity. HYPOTHESIS Quantitative reproductible Terres Minor assessment on CT estimates the influence of muscle trophicity on the clinical and radiological results of palliative treatment of irreparable rotator cuff tear. MATERIALS AND METHOD An anatomic study of 30 cadaveric shoulders confirmed a constant anatomic relation between Terres Minor and the inferior pole of the glenoid cavity. This landmark was used to develop a novel CT assessment of TM trophicity. RESULTS The CT assessment showed excellent inter- and intra-observer reproductibility. The protocol defines a trophicity index, T2/G (T2 being TM thickness on axial CT slice, and G the maximum glenoid cavity thickness on axial slice), enabling reproductible TM analysis on preoperative arthro-CT. CONCLUSION The study validated the CT protocol, allowing application in pre- and postoperative assessment of irreparable rotator cuff tear. LEVEL OF EVIDENCE Level IV. Retrospective study.

Abstract
PURPOSE Our aim was to assess the clinical and radiological outcomes of reverse shoulder replacements performed in association with a latissimus dorsi and teres major tendon transfer in cases of irreparable posterosuperior cuff tears including the teres minor tendon. Our hypothesis was that the tendon transfers would improve the clinical results of arthroplasty by restoring active external rotation. METHODS Fifteen procedures in 14 patients were performed through a single deltopectoral approach. Both tendons were fixed to the proximal anterolateral aspect of the humeral metaphysis. Mean age at the time of surgery was 67.5 years (range 53 to 82 years). All had severe cuff tear arthropathy (Hamada stage 3 or 4) and severe atrophy or fatty infiltration of the infraspinatus and teres minor on preoperative MRI or CT-scan (Goutallier stage 3 or 4). Preoperative and postoperative functions were assessed by Constant score. Satisfaction was assessed by the Simple Shoulder Test (SST). At follow up, radiographs were examined for radiolucent lines, osteolysis and scapular notching. RESULTS The average follow-up after surgery was 33.2 months (range 24 to 60 months). The mean absolute Constant score improved significantly (P=10(-5)) from 23.7±11.5 preoperatively to 61.1±11.9 postoperatively. Forward flexion and external rotation with the arm at the side improved significantly, respectively from 64.7±35.6° preoperatively to 126±34.4° postoperatively (P<10(-5)) and from -8.7±21.3° to 27.3±12.2° (P<0.0005). Internal rotation was not affected. The mean SST improved from 1.9±1.6 points preoperatively to 7.6±1.8 points postoperatively (P<0.0005). Twelve patients were very satisfied or satisfied (including one with a bilateral procedure) and 2 were unsatisfied with the final result. At final follow-up, radiographs showed no radiolucent lines around the implants nor scapular notching. CONCLUSION The combined procedure helped restoration of active elevation and external rotation in cases of massive cuff tear including the teres minor tendon. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Latissimus dorsi transfer is a well-established method for the treatment of posterosuperior massive irreparable rotator cuff tears. We propose using an arthroscopically assisted technique that avoids insult to the deltoid. With the patient in the lateral decubitus position, an L-shaped incision is made along the anterior belly of the latissimus muscle and then along the posterior axillary line. The latissimus and teres major are identified and separated. The tendon insertion of the latissimus is isolated, and a FiberWire traction suture (Arthrex, Naples, FL) is placed, facilitating dissection of the muscle to the thoracodorsal neurovascular pedicle and subsequent mobilization. The interval deep to the deltoid and superficial to the teres minor is developed into a subdeltoid tunnel for arthroscopic tendon transfer. The latissimus tendon is then transferred and stabilized arthroscopically to the lateral aspect of the infraspinatus and supraspinatus footprints by multiple suture anchors.

Abstract
The teres major (TerMa) muscle has a clinical significance for tendon transfer procedures in patients with massive rotator cuff tears. Individually, it originates from the dorsum of the inferior angle of scapula and inserts into the medial lip of bicepital groove of the humerus. Functionally, TerMa in cooperation with latissimus dorsi (LD) adducts arm, medially rotates arm, and assists in arm extension. The variation of TerMa insertion is very rare. In the shoulder and axillary regions of a 33-year-old Thai male cadaver, the variant insertion of the right TerMa was found. The muscle fibers of TerMa are directly attached at the supero-medial border of LD tendon. Notably, there was no terminal tendon of TerMa. To explain an unusual movement of the arm, this rare variation of the TerMa insertion is necessary to be recognized. This case report is very important for surgeons to preoperatively consider using the terminal tendon of TerMa for tendon transfer in treating patients with irreparable cuff tears.

Abstract
BACKGROUND Diagnostic evaluation of rotator cuff muscle quality is important to determine indications for potential operative repair. Ultrasonography has developed into an accepted and useful tool for evaluating rotator cuff tendon tears; however, its use for evaluating rotator muscle quality has not been well established. The purpose of this study was to investigate the diagnostic performance and observer reliability of ultrasonography in grading fatty degeneration of the posterior and superior rotator cuff muscles. METHODS The supraspinatus, infraspinatus, and teres minor muscles were prospectively evaluated with magnetic resonance imaging (MRI) and ultrasonography in eighty patients with shoulder pain. The degree of fatty degeneration on MRI was graded by four independent raters on the basis of the modified Goutallier grading system. Ultrasonographic evaluation of fatty degeneration was performed by one of three radiologists with use of a three-point scale. The two scoring systems were compared to determine the diagnostic performance of ultrasonography. The interobserver and intraobserver reliability of MRI grading by the four raters were determined. The interobserver reliability of ultrasonography among the three radiologists was determined in a separate group of thirty study subjects. The weighted Cohen kappa, percentage agreement, sensitivity, and specificity were calculated. RESULTS The accuracy of ultrasonography for the detection of fatty degeneration, as assessed on the basis of the percentage agreement with MRI, was 92.5% for the supraspinatus and infraspinatus muscles and 87.5% for the teres minor. The sensitivity was 84.6% for the supraspinatus, 95.6% for the infraspinatus, and 87.5% for the teres minor. The specificity was 96.3% for the supraspinatus, 91.2% for the infraspinatus, and 87.5% for the teres minor. The agreement between MRI and ultrasonography was substantial for the supraspinatus and infraspinatus (kappa = 0.78 and 0.71, respectively) and moderate for the teres minor (kappa = 0.47). The interobserver reliability for MRI was substantial for the supraspinatus and infraspinatus (kappa = 0.76 and 0.77, respectively) and moderate for the teres minor (kappa = 0.59). For ultrasonography, the interobserver reliability was substantial for all three muscles (kappa = 0.71 for the supraspinatus, 0.65 for the infraspinatus, and 0.72 for the teres minor). CONCLUSIONS The diagnostic performance of ultrasonography in identifying and grading fatty degeneration of the rotator cuff muscles was comparable with that of MRI. Ultrasonography can be used as the primary diagnostic imaging modality for fatty changes in rotator cuff muscles.

Abstract
BACKGROUND Massive and irreparable posterior-superior rotator cuff tears present a difficult treatment problem. The purpose of this systematic review was to critically examine the outcomes of latissimus dorsi tendon transfers for the treatment of irreparable rotator cuff tears. METHODS A systematic review of the literature was performed via a search of electronic databases. Two reviewers independently assessed the methodological quality of, and extracted relevant data from, each included study. In cases in which the outcomes data were similar between studies, data were pooled for the purposes of generating summary outcomes through the use of frequency-weighted values. RESULTS Ten studies that fulfilled all inclusion and exclusion criteria were included. The frequency-weighted mean age was 58.7 years. Patients were followed for a frequency-weighted mean of 45.5 months (range, twenty-four to 126 months). Patients had a frequency-weighted mean adjusted Constant score of 45.9 preoperatively compared with 73.2 postoperatively (p < 0.001). The frequency-weighted mean active forward elevation improved from 101.9° preoperatively to 137.4° postoperatively (p < 0.001), and the frequency-weighted mean active external rotation improved from 16.8° to 26.7° (p < 0.001). Subscapularis muscle insufficiency, advanced teres minor muscle atrophy, and the need for revision surgery were correlated with poor functional outcomes in some studies. CONCLUSIONS Compiled data and frequency-weighted means demonstrated improvement in shoulder function, range of motion, strength, and pain relief after latissimus dorsi tendon transfer for irreparable rotator cuff tears. Patients and physicians should not expect an outcome of "normal" function or complete pain relief.

Abstract
Tendon transfers have been proposed as a possible solution to restore pain-free functions, strength, and range of motion in patients with massive and irreparable cuff tears. The aim of this review is to establish the outcomes of (1) latissimus dorsi tendon transfer (LDT-T) surgery performed as a single procedure or in combination with other muscle-tendon transfer procedures, replacement, or both; (2) LDT-T in primary and revision surgery for massive irreparable rotator cuff tears; (3) the LDT-T procedure in relation to subscapularis and teres minor integrity; (4) the LDT-T procedure in relation to the reattachment position on the humeral head of the transferred tendon; (5) the LDT-T procedure performed as a single or a double incision; (6) arthroscopic, open, or combined approach: and (7) the LDT-T procedure in patients with preoperative osteoarthritis and a nonosteoarthritic condition with the evaluation of osteoarthritis progression. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Studies of levels of evidence I-IV were included. The LDT-T surgical procedure, outcomes, and complications were evaluated. Twenty-two studies describing 493 shoulders in 487 patients were included in our study. There were no prospective randomized, controlled studies. LDT-T is a promising strategy for the management of massive and irreparable rotator cuff tears, even though no agreement was found on several aspects and options of LDT-T. Randomized prospective control studies are still awaited on this subject.

Abstract
BACKGROUND The fixation of the tendon to the bone remains a challenging problem in the latissimus dorsi tendon transfer for irreparable cuff tears and can lead to unsatisfactory results. A new arthroscopic method of tendon to bone fixation using an interference screw has been developed and the purpose of this study was to compare its biomechanical properties to the ones of a standard fixation technique with anchors. METHODS Six paired fresh frozen cadaveric human humeri were used. The freed latissimus dorsi tendon was randomly fixed to the humeral head with anchors or with interference screw after a tubularization procedure. Testing consisted to apply 200 cycles of tensile load on the latissimus dorsi tendon with maximal loads of 30 N and 60 N, followed by a load to failure test. The stiffness, displacements after cyclic loadings, ultimate load to failure, and site of failure were analysed. FINDINGS The stiffness was statistically higher for the tendons fixed with interference screws than for the ones fixed with anchors for both 30 N and 60 N loadings. Likewise, the relative bone/tendon displacements after cyclic loadings were lower with interference screws compared to anchors. Load to failure revealed no statistical difference between the two techniques. INTERPRETATION Compared to the standard anchor fixation, the interference screw fixation technique presents higher or similar biomechanical performance. These results should be completed by further biomechanical and clinical trials to confirm the interest of this new technique as an alternative in clinical use.

The teres minor muscle in rotator cuff tendon tears. Skeletal Radiol 2011; 40:1335-44.

Abstract
OBJECTIVES Although the teres minor has received little attention in the literature compared to the other musculotendinous units of the rotator cuff, it is an important component of shoulder function. Our purpose was to study the appearance of the teres minor muscle on CT and MRI images in various patterns of rotator cuff tears. MATERIALS AND METHODS We analyzed the appearance of the teres minor according to the Walch classification (normal, hypertrophic, atrophic, or absent) in 1,332 CT and in 240 MRI images of rotator cuff tears and we correlated it with the type of rotator cuff tears, time period between initial onset of symptoms and diagnostic imaging, age of the patient at the time of imaging, and degree of fatty infiltration of other rotator cuff muscles. RESULTS The teres minor was classified as normal in 90.8% of cases, hypertrophic in 5.8%, atrophic in 3.2%, and absent in 0.2%. Significant variability existed in the appearance of the teres minor muscle among different patterns of rotator cuff tears in the CT (P < 0.0001) and MRI groups (P < 0.0001). The teres minor appeared most frequently hypertrophic in anterior tears and atrophic in posterior-superior tears. CONCLUSIONS The teres minor was normal in most rotator cuff tears. A morphologic classification system allowed the appearance of the teres minor to be defined in isolated and multiple rotator cuff tears in CT and MRI images.

Abstract
BACKGROUND Latissimus dorsi tendon transfer is a well-established method for the treatment of massive irreparable posterosuperior defects of the rotator cuff. Subsequent rupture of the transferred tendon may contribute to the rate of failure of the index procedure. We hypothesized that modification of our technique of tendon harvesting would lead to greater fixation stability and a reduced failure rate. METHODS Forty-two patients (mean age, fifty-eight years) with a massive irreparable posterosuperior tear of the rotator cuff were managed with a latissimus dorsi tendon transfer. Sharp separation of the latissimus tendon from the humerus was performed in twenty-two patients (Group A), whereas the tendon harvest was carried out with a modified technique that involved removal of some bone along with the tendon at the humeral insertion in a subsequent group of twenty patients (Group B). The mean duration of follow-up was forty-seven months. Outcome measures included the Constant and American Shoulder and Elbow Surgeons (ASES) scores and a patient subjective satisfaction scale. Standard radiographs were made to determine the stage of osteoarthritis and proximal migration of the humeral head, and magnetic resonance imaging was performed to assess the integrity of the transferred muscle. RESULTS In Group A, the mean Constant score improved from 43.4 preoperatively to 64.8 points at the time of follow-up and the mean ASES score improved from 49.3 to 69.6 points (p < 0.05). In Group B, the mean Constant score increased from 40.2 to 74.2 points and the mean ASES score, from 47.2 to 77.1 points (p < 0.05). The Constant pain score improved from 5.6 to 11.9 points in Group A and from 5.2 to 13.8 points in Group B. The results in Group B were significantly superior to those in Group A (p < 0.05). Magnetic resonance imaging revealed complete rupture at the tendon insertion with tendon retraction in four patients in Group A and none in Group B. The final outcome was rated as poor in 27% of the patients in Group A and in 10% in Group B. CONCLUSIONS Latissimus dorsi tendon transfer achieves satisfactory clinical results in most patients who have a massive irreparable posterosuperior tear of the rotator cuff. Harvesting the tendon along with a small piece of bone enables direct bone-to-bone transosseous fixation, resulting in better tendon integrity and clinical results.

Abstract
Repair of massive rotator cuff tears is technically difficult but often feasible. Technical and biological challenges to a successful repair include inelastic poor-quality tendon tissue, scarring, muscle atrophy, and fatty infiltration. Fatty infiltration of the involved rotator cuff muscles has been identified as an important negative prognostic factor for the outcome after repair of massive rotator cuff tears. Tendon transfer is a good option for young patients and manual laborers with an irreparable massive rotator cuff tear. Arthroplasty can be considered for the treatment of symptomatic massive rotator cuff tears in patients who have glenohumeral arthritis.

Abstract
UNLABELLED Patients with posterosuperior cuff tears lose functional external rotation of the shoulder. Latissimus dorsi and teres major transfer is performed to restore external rotation. Twenty patients with a mean age was 55.8 +/- 6 years underwent this procedure and were examined at averages of 24.7 (n = 17) and 70.6 (n = 13) months. Two patients did not improve presumably because of failure of the transfer. The Constant and Murley score increased from 55.6 to 90.4 after 2 years and to 87.9 after 5 years. The mean active flexion increased from 119.4 degrees to 169.3 degrees and reached 170 degrees after 5 years, and mean external rotation increased from 12 degrees to 35 degrees , finally reaching 23 degrees . The grade of cuff arthritis progressed from initially Grade 1 in 17% and Grade 2 in 28% to Grade 2 in 8%, Grade 3 in 69%, and Grade 4 in 15% at final followup. The acromiohumeral distance increased from 4.5 mm to 6 mm and decreased to 3.8 mm after 5 years. Electromyographic analysis showed activity during isometric internal and external rotation in the transferred muscle in all patients. The L'Episcopo procedure can restore shoulder function, but cuff arthropathy may progress. LEVEL OF EVIDENCE Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Abstract
The purpose of this study was to evaluate the outcome of deltoid muscle flap transfer for the treatment of irreparable rotator cuff tears. In a retrospective study 20 consecutive patients were evaluated. The index procedure took place between 2000 and 2003. Fifteen patients were male, mean age was 62 years. Inclusion criterion was a rotator cuff defect Bateman grade IV. Exclusion criteria were smaller defects, shoulder instability and fractures of the injured shoulder. An open reconstruction with acromioplasty and a pedicled delta flap was performed. Follow up period was mean 42 months. Follow-up included clinical examination, Magnetic Resonance Imaging (MRI) and the Constant and Simple (CS) shoulder tests. According to the Constant shoulder test the results were good in 13 patients, fair in 5 and unsatisfactory in 2. The pre-operative Constant Score improved from mean 25.7 points (±5.3) to 72.3 (±7.8) at follow-up. The mean values for the subcategories of CS increased significantly from 3.9 to 14.4 points for pain and from 4.2 to 15.9 points for activities daily routine (p<0.05). The change in range of motion and strength were not significant (p>0.05). Results of the Simple Shoulder Test showed a significant increase of the mean values from pre-operative 4.3 to 14.7 points post-operatively. MRI showed a subacromial covering of the defect in all cases, all flaps where intact on MRI but always the flap showed marked fatty degeneration. In conclusion, the delta flap is a simple method for the repair of large defects of the rotator cuff leading to satisfying medium results.
