Arthroscopic repair for isolated subscapularis tear: successful functional outcomes and high tendon healing rate can be expected nine years after surgery. J Shoulder Elbow Surg 2024; 33:1285-1292. [PMID: 38036257 DOI: 10.1016/j.jse.2023.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 10/03/2023] [Accepted: 10/22/2023] [Indexed: 12/02/2023]
Abstract
BACKGROUND Literature describing outcomes and integrity after isolated subscapularis (SSC) tendon repair is emerging but remains limited to a few small case series with short-term follow-up. The aim of this study was to evaluate the long-term clinical outcomes and repair integrity in patients who underwent arthroscopic repair of isolated SSC tears. METHODS A retrospective study was conducted with the following inclusion criteria: (1) primary and elective shoulder arthroscopy for isolated SSC repair, (2) type III (a full-thickness tear in the upper two-thirds of the tendon) or IV (a complete tear without tendon retraction) SSC tear according to the Lafosse classification, and (3) a minimum 24-month follow-up. Preoperatively, the range of motion (ROM) and the Constant-Murley score (CMS) and at follow-up, the ROM, the University of California-Los Angeles (UCLA) Shoulder Rating Scale, the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and the CMS were evaluated; an ultrasonographic assessment of tendon healing was performed according to the Sugaya classification. RESULTS The final sample consisted of 45 patients with an average age of 55 ± 9 years. After a mean follow-up time of 107 ± 54 months, the mean UCLA and DASH scores were 8.7 ± 1.3 and 42.2 ± 6.4, respectively. ROM and CMS showed statistically significant improvements (all P < .001). Before surgery, the mean CMS was 49% that of sex- and age-matched healthy individuals, and all patients showed a CMS lower than the normative data. At the final follow-up visit, the mean CMS was 94.2% that of sex- and age-matched healthy individuals, and no patients showed CMS of 30 or less. The mean increase in the CMS was 41.4 ± 9.8 points (range, 23-60 points). The ultrasonographic assessment showed SSC tendon healing in 39 (86.7%) cases; tendon retear was recorded in 5 (13.3%) cases. All scores directly correlated with the healing of the tendon. A higher postoperative DASH score was associated with male sex (P = .039, β = 5.538) and a longer follow-up period (P = .044, β = 0.001). The postoperative CMS (P < .001) and UCLA scores (P = .001) were significantly higher in patients younger than 60 years of age at surgery than in older individuals. CONCLUSION Arthroscopic repair of isolated SSC tears achieves excellent clinical and functional results at a mean of 9 years postoperatively, with a satisfactory healing rate. Better functional outcomes correlate with SSC tendon integrity and were observed in male patients and in those younger than 60 years at surgery.

Abstract
Rotator cuff tendinopathy, a major cause of shoulder disability, occurs due to trauma or degeneration. Our molecular understanding of traumatic and degenerative tears remains elusive. Here, we probed transcript level differences between traumatic and degenerative tears. Subacromial bursa tissues were collected from patients with traumatic or degenerative tears during arthroscopy (N = 32). Transcripts differentially expressed by tear etiology were detected by RNA-seq. RNA-seq results were validated by real-time quantitative polymerase chain reaction. We identified 334 protein-coding transcripts differentially expressed between traumatic and degenerative tears in females and 167 in males at a fold-change greater than 2. In females, XIRP2, MYL1, MYBPC1, TNNT1, and LMOD2, were highly expressed in traumatic tears whereas TPSD1, CDSN, RCVRN, LTBP4, and PTGS1 were elevated in degen tears. Transcripts elevated in traumatic tears represented muscle cell differentiation and development, and muscle contraction whereas those elevated in degenerative tears represented cell activation and immune response. In males, AZGP1, CNTFR, COL9A1, ZNF98, and EREG were highly elevated in traumatic tears whereas MYL2, HOXD11, SLC6A7, CADM1, and MMP17 were highly expressed in degenerative tears. Transcripts elevated in traumatic tears represented metabolic/catabolic processes, and transmembrane protein transport while processes related to cell cycle were mainly enriched in degenerative tears. Numerous long noncoding RNAs were differentially expressed between traumatic and degenerative tears in both sexes. In summary, this study provides insights into molecular biology of bursa in patients with rotator cuff tendon disease based on tear acuity and novel sex-based transcript differences that could inform clinical decision making in treating patients with traumatic or degenerative shoulder injuries.

Abstract
Our aim was to systematically review literature of trauma related rotator cuff tears in order to evaluate the outcome and healing integrity in relation to time of surgery. Our research question was whether earlier surgical repair leads to superior functional results. This review was conducted according to PRISMA statement. A literature search of Pubmed, Embase, Cohrane was conducted, with two researchers assessing studies for eligibility and quality. A total of 20 studies, published between 1980 and 2019, met the inclusion criteria and were divided into two groups based on duration of symptoms before surgery. Group A comprised of studies in which duration was < 3 months and Group B > 3 months. Within each group there was a statistically significant improvement in the CS from pre-operative to post-operative outcome, but the improvement for Group A was statistically higher in comparison to Group B (P=0.01). Nevertheless, there was no significant difference in the final outcome for the two groups (P=0.29). The re-tear rate per 100 patients was calculated 28.5(±7.2) for Group A, and 17.2 (±12.56) for Group B (P=0.056). Our results suggest that functional outcome and tendon healing may not be valid arguments for early surgical repair. Therefore, repair of traumatic RCTs could be recommended whenever technically possible.

Abstract
Background Available surveys that evaluate shoulder strength and pain often combine rotator cuff muscles making the test unable to differentiate subscapularis tears from other pathology including concomitant supraspinatus, infraspinatus tears. The purpose of this study was to validate a subscapularis-specific shoulder survey (Baltimore Orthopedic Subscapularis Score) as a viable clinical outcome assessment through analysis of psychometric properties. Methods A 5-question survey was given to a study population of 390 patients, 136 of whom had full thickness rotator cuff tears with a minimum score of 5 (better) and a maximum score of 25 (worse). Surveys were given during the initial consultation, preoperative visit, and postoperative visit. Content validity, construct validity, test-retest reliability, responsiveness to change, internal consistency, and minimal clinically important difference using distribution and anchor-based methods were determined for our subscapularis function survey. Results A high correlation was reported on test-retest reliability (intraclass correlation coefficient = 0.89). An acceptable internal consistency was reported for all patients surveyed (Cronbach alpha = 0.91). Floor and ceiling effects for patients with rotator cuff pathology were minimized (1% for both). Patients with an isolated subscapularis tear scored worse than supraspinatus/infraspinatus tears and exhibited similar dysfunction as patients with a supraspinatus/infraspinatus/subscapularis tear. An acceptable construct validity was reported with subscapularis-involved tears demonstrating higher scores with significance (P < .05). There was excellent responsiveness to change with a standardized response mean of 1.51 and effect size of 1.27 (large > 0.8). The minimal clinically important difference using a distribution and anchor-based method was 4.1 and 4.6, respectively. Among patients with rotator cuff tears in this population, a score of 22 or higher predicts a subscapularis tear 75% of the time, in spite of its low overall prevalence. Conclusion The subscapularis shoulder score demonstrated acceptable psychometric performance for outcomes assessment in patients with rotator cuff disease. This survey can be used as an effective clinical tool to assess subscapularis function.

Abstract
PURPOSE This study aimed to determine the role of preoperative shoulder ultrasonography (SUS) in detecting positional abnormalities of the long head of the biceps tendon (LHBT) and predicting subscapularis (SSC) tears in patients with rotator cuff injuries. METHODS A total of 331 patients (365 shoulders) who had undergone arthroscopic shoulder surgery for the treatment of rotator cuff tears were included in the study. Their preoperative SUS and magnetic resonance imaging (MRI) findings were examined retrospectively to assess the presence of LHBT abnormalities at the bicipital groove. Using arthroscopic findings as the standard of reference, the sensitivity, specificity, and diagnostic accuracy of SUS and MRI were calculated for detection of LHBT malposition. Furthermore, the correlation between SSC rupture and preoperative LHBT condition was evaluated by MRI and SUS. RESULTS LHBT malposition was preoperatively diagnosed with a sensitivity of 92%, specificity of 90%, and accuracy of 91% with SUS, and a sensitivity of 74%, specificity of 84%, and accuracy of 80% with MRI. Preoperative SUS was significantly superior to MRI in terms of sensitivity, specificity, and accuracy (p < 0.001 each). Further, the preoperative SUS LHBT findings could predict well the presence or absence of intraoperative SSC rupture (odds ratio: 1.73, p < 0.001). CONCLUSION SUS is a useful diagnostic modality for preoperative detection of LHBT malposition and prediction of SSC tears in patients with rotator cuff tears.

[PMID: 35309232 PMCID: PMC8928393 DOI: 10.1177/23259671221083591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Accepted: 12/08/2021] [Indexed: 11/25/2022] Open
Abstract
Background: Both knotted and knotless single-anchor repair techniques are used to repair transmural ruptures of the upper subscapularis (SSC) tendon. However, it is still unclear which technique provides better clinical and radiological results. Purpose/Hypothesis: To compare the clinical and magnetic resonance imaging (MRI) outcomes of knotless and knotted single-anchor repair techniques in patients with a transmural rupture of the upper SSC tendon at 2-year follow-up. It was hypothesized that the 2 techniques would not differ significantly in outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Forty patients with a transmural tear of the upper SSC tendon (grade 2 or 3 according to Fox and Romeo) were retrospectively enrolled. Depending on the repair technique, patients were assigned to either the knotless single-anchor or knotted single-anchor group. After a mean follow-up of 2.33 ± 0.43 years, patients were assessed by the ASES, WORC, OSS, CS, and SSV. A clinical examination that included the bear-hug, the lift-off, and the belly-press tests was performed, in which the force exerted by the subjects was measured. In addition, all patients underwent MRI of the affected shoulder to assess repair integrity, tendon width, fatty infiltration, signal-to-signal ratio of the upper and lower SSC muscle, and atrophy of the SSC muscle. Results: No significant difference was found between the 2 groups on any of the clinical scores [ASES (P = .272), WORC (P = .523), OSS (P = .401), CS (P = .328), SSV (P = .540)] or on the range-of-motion or force measurements. Apart from a higher signal-to-signal ratio of the lower SSC muscle in the knotless group (P = .017), no significant difference on imaging outcomes was found between the 2 groups. Conclusion: Both techniques can be used in surgical practice, as neither was found to be superior to the other in terms of clinical or imaging outcomes at 2-year follow-up.

Abstract
PURPOSE A simple fall on the shoulder is often referred to as minor trauma that cannot cause a tendon tear but at best reveal a pre-existing rotator cuff pathology. We wanted to know whether this statement was true. The purpose of our study was therefore to summarize the causes of acute rotator cuff tears reported in the literature and provide a biomechanical explanation for tendon tears diagnosed after a fall. METHOD We searched PubMed and included studies reporting rotator cuff tears occurring due to a trauma. The number of cases, the tendons involved, the age of the patients, and the nature of trauma were summarized. In addition, we noted any information provided by the authors on the pathogenesis of acute tendon ruptures. RESULTS Sixty-seven articles with a total of 4061 traumatic rotator cuff tears met the inclusion criteria. A simple fall was the most common cause (725 cases) and the supraspinatus tendon was most frequently affected. The postulated pathomechanism is a sudden stretch of the tendon-muscle unit while contracting (eccentric loading). CONCLUSION A simple fall can cause an acute rotator cuff tear and fall-related tears are not restricted to young individuals. They can affect patients of any age. The stresses occurring within the rotator cuff during an attempt to cushion a fall may locally exceed the tensile strength of the tendon fibers and cause a partial or full-thickness tear.

Abstract
Addressing subscapularis tendon pathology has garnered increased attention during shoulder arthroscopy in attempt to adequately restore glenohumeral force couples. The appropriate rebalancing of force couples of the rotator cuff musculature by repairing subscapularis tendon tears in patients with large rotator cuff tears has been shown to improve functional outcomes while decreasing retear rates. However, subscapularis tendon tears may be particularly challenging to diagnose and present a significant degree of technical difficulty with the description of multiple arthroscopic and open surgical techniques. In this comprehensive guide, we put forth a simple, concise, and reproducible arthroscopic technique using a Clever Hook and Lasso Loop stitch technique for repairing both high-grade partial and full-thickness tears of the subscapularis tendon.

Abstract
Orthopaedic practices have been markedly affected by the emergence of the COVID-19 pandemic. Despite the ban on elective procedures, it is impossible to define the medical urgency of a case solely on whether a case is on an elective surgery schedule. Orthopaedic surgical procedures should consider COVID-19-associated risks and an assimilation of all available disease dependent, disease independent, and logistical information that is tailored to each patient, institution, and region. Using an evidence-based risk stratification of clinical urgency, we provide a framework for prioritization of orthopaedic sport medicine procedures that encompasses such factors. This can be used to facilitate the risk-benefit assessment of the timing and setting of a procedure during the COVID-19 pandemic.

Abstract
Hypothesis The purpose was to evaluate long-term clinical outcomes and tendon structural integrity after repair of isolated subscapularis (SSC) tendon tears. Methods Sixty-one patients who underwent repair of isolated SSC tears were evaluated. The mean interval from symptom onset to surgery was 5.3 months. Shoulder function was investigated using the Constant score and Subjective Shoulder Value (SSV). Structural integrity of the repair and quality of the repaired tendon were assessed using magnetic resonance imaging. Independent preoperative factors affecting clinical outcomes, including patient sex, age, smoking habits, injections, dominant shoulder, profession, and tear onset (chronic vs. traumatic), were evaluated. Results A total of 35 patients (9 women and 26 men; mean age, 54 years) were included at the final 10-year follow-up because 21 patients were lost to follow-up and 5 underwent reoperations. The mean Constant score improved from 55.1 points preoperatively to 75.4 points postoperatively (P = .001). The postoperative SSV was 80.9, and the retear rate was 12.9%. Postoperative fatty infiltration increased in 26% of the patients with grades 3-4, but it was not related to lower clinical outcomes. Multivariable regression analysis revealed no correlation among the preoperative factors, including sex, age, smoking habits, injections, dominant shoulder, profession, and tear onset, and the postoperative Constant score, SSV, and tendon healing. Conclusion At a mean of 10 years after repair of isolated SSC tears, clinical results were satisfactory and functional improvement was maintained in the long term. Severe fatty infiltration increased with time, but it was not related to clinical outcomes and the retear rate.

Orthop J Sports Med 2020; 8:2325967119899355. [PMID: 32118080 PMCID: PMC7029597 DOI: 10.1177/2325967119899355] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Accepted: 10/09/2019] [Indexed: 11/23/2022] Open
Abstract
Background: Few studies have compared the clinical and radiological characteristics and outcomes in isolated subscapularis (SSC) and combined anterosuperior (AS) rotator cuff tears (RCTs). Furthermore, risk factors for retear after SSC repair and the effect of preoperative fatty degeneration require further evaluation. Purpose: To compare the functional and radiological outcomes of isolated SSC with combined AS RCTs after arthroscopic repair and to determine the risk factors for SSC retear in these 2 groups. Study Design: Cohort study; Level of evidence, 3. Methods: Data from 30 patients in the isolated SSC group were compared with data from 110 patients in the combined AS group. All patients underwent primary arthroscopic rotator cuff repair between 2010 and 2016. Clinical outcomes were assessed through use of the visual analog scale for pain, American Shoulder and Elbow Surgeons score, and Simple Shoulder Test at a mean follow-up of 26.7 months (range, 24-96 months). SSC tendon integrity was examined via magnetic resonance imaging, computed tomography arthrogram, or ultrasonography at least 1 year after surgery. Results: The isolated SSC group had a greater proportion of males and the patients were younger compared with the combined AS group (both P < .050). The incidence of trauma was high but not significantly different between groups (56.7% vs 40.9%; P = .180). Clinical outcome measures and radiological outcomes in terms of retear were not statistically different between both groups (16.7% vs 8/5%; P = .337). The optimal cutoff values for the risk of SSC tendon retear in both groups were 19-mm retraction and 16-mm superoinferior dimension (P = .048). Unfavorable preoperative fatty degeneration of the SSC muscle (grades 3 and 4) was a significant risk factor for retear (odds ratio, 9.8; P < .001). Conclusion: Isolated SSC and combined AS RCTs were comparable except for patient age and sex; both had a high incidence of traumatic history. The current data suggest that the risk factors for retear after SSC repair in RCTs involving the SSC were tear size greater than 19 mm of retraction and unfavorable fatty degeneration (grade 3 or higher) of the SSC muscle.

Repair failure increases the risk of developing secondary glenohumeral osteoarthritis: A long-term follow-up after open repair of large subscapularis tendon tears. Orthop Traumatol Surg Res 2019; 105:1529-1533. [PMID: 31732397 DOI: 10.1016/j.otsr.2019.09.021] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 08/21/2019] [Accepted: 09/17/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND The subscapularis musculotendinous unit provides a stabilizing effect on the glenohumeral joint and thus, enables normal active range of motion. As pathologies of the subscapularis tendon (SSC) are diagnosed with increased regularity, treatment strategies and their long-term consequences are of relevant interest. Therefore, the primary objective of this retrospective case series was to evaluate clinical and radiological long-term results after open repair of large SSC tears. HYPOTHESIS Repair failure negatively influences clinical outcomes and the progression of secondary glenohumeral osteoarthritis (OA). METHODS Between 1998 and 2007, 24 patients with traumatic large (Lafosse III and IV) SSC tears were treated with an open transosseous repair technique. Of those, 20 patients (83%) with a mean age of 55±8 years (range, from 31 to 68 years) at the time of surgery were subjected to a long-term follow-up after a mean of 14±3 years (range, from 10 to 18 years). The Subjective Shoulder Value (SSV), the Constant Score (CS), the University of California at Los Angeles (UCLA) Shoulder Score, and the American Society for Shoulder and Elbow Surgeons (ASES) Score were obtained. Magnetic resonance imaging (MRI) was performed to evaluate tendon integrity. The progression of secondary glenohumeral OA from pre- to postoperative was analyzed using the collective instability arthropathy (CIA) score. RESULTS One patient (5%) had to undergo revision surgery due to a symptomatic re-tear of the SSC tendon. Besides that, the mean SSV of the affected shoulder was 83%±12, the CS 78±10, the UCLA 32±2, and the ASES 89±14 points, respectively. MRI revealed a re-tear of the SSC tendon in 4 patients (29%). On the affected shoulder, glenohumeral OA progressed significantly from pre- (CIA, 0.3±0.5) to postoperative (CIA, 1.7±0.9; p=0.003) and was significantly associated with repair failure (p=0.040). CONCLUSION Open repair of large SSC tears yielded good clinical long-term results. Nevertheless, repair failure was common and, in the further course, negatively affected clinical outcomes and the progression of secondary glenohumeral OA. LEVEL OF EVIDENCE IV; retrospective case series.

Abstract
BACKGROUND In the event of a traumatic rotator cuff tear, patients are routinely advised that early surgical intervention produces an optimal repair, despite a lack of direct evidence to support this recommendation. To address this knowledge gap, massive rotator cuff tears in rats were assessed by biomechanical and bone morphometric analyses after early or late repair. METHODS Combined supraspinatus and infraspinatus tendon tears of the left shoulder were created in 21 adult Wistar rats, which were divided into 2 groups. The tendons of the injured shoulder in the animals in group I were surgically repaired 8 weeks after the injury. Under the same anesthesia, the same injury was created on the right shoulder, which was immediately repaired. The rats from group I were euthanized 8 weeks after the repairs. No repair was performed in the rats from group II, which were euthanized 8 weeks after the injury. Tissues from both groups were harvested and biomechanically tested for supraspinatus tendon and bone morphometry analysis of the humeral head. RESULTS All biomechanical properties were significantly increased in the early repair group compared with the late repair group. No significant differences were observed in bone morphometry of the humeral head when early and late repair groups were compared. CONCLUSION Early surgical repair of a massive rotator cuff tear leads to improved biomechanical properties of the tissue after healing. Proximal humerus bone morphometry was unaffected by surgical repair timing.

Abstract
OBJECTIVE Reconstruction of tendon integrity to maintain glenohumeral joint centration and hence to restore shoulder functional range of motion and to reduce pain. INDICATIONS Isolated or combined full-thickness subscapularis tendon tears (≥upper two-thirds of the tendon) without both substantial soft tissue degeneration and cranialization of the humeral head. CONTRAINDICATIONS Chronic tears of the subscapularis tendon with higher grade muscle atrophy, fatty infiltration, and static decentration of the humeral head. SURGICAL TECHNIQUE After arthroscopic three-sided subscapularis tendon release, two double-loaded suture anchors are placed medially to the humeral footprint. Next to the suture passage, the suture limbs are tied and secured laterally with up to two knotless anchors creating a transosseous-equivalent repair. POSTOPERATIVE MANAGEMENT The affected arm is placed in a shoulder brace with 20° of abduction and slight internal rotation for 6 weeks postoperatively. Rehabilitation protocol including progressive physical therapy from a maximum protection phase to a minimum protection phase is required. Overhead activities are permitted after 6 months. RESULTS While previous studies have demonstrated superior biomechanical properties and clinical results after double-row compared to single-row and transosseous fixation techniques, further mid- to long-term clinical investigations are needed to confirm these findings.

Reverse shoulder arthroplasty for irreparable massive rotator cuff tears: a systematic review with meta-analysis and meta-regression. J Shoulder Elbow Surg 2017; 26:e265-e277.

Abstract
BACKGROUND Massive rotator cuff tears (MRCTs) are very large tears that are often associated with an uncertain prognosis. Indeed, some MRCTs even without osteoarthritis are considered irreparable, and nonanatomic solutions are needed to improve the patient's symptoms. Reverse shoulder arthroplasty (RSA) is an option that can provide a more predictable pain relief and recovery of function. Nonetheless, outcomes after RSA for irreparable MRCTs have not been well defined. The aim of this study was to quantitatively aggregate the findings associated with the use of RSA in this subset of patients and analyze the effect on patient functional status and pain. METHODS A comprehensive search was performed until October 2015 using MEDLINE, Scopus, Cochrane Database of Systematic Reviews, and Central Register of Controlled Trials databases. Studies that assessed the outcomes of RSA in patients with irreparable MRCT without osteoarthritis (with at least 2 years of follow-up) were included. If the results of MRCT without osteoarthritis were not possible to subgroup, the study was excluded. Methodologic quality was assessed using the Coleman Methodology Score. RESULTS Included were 6 studies (266 shoulders) with a follow-up ranging from 24 to 61.4 months. The mean Coleman Methodology Score was 58.2 ± 11.8 points. There was an overall improvement from preoperative to postoperative assessments of the clinical score (Cohen d = 1.35, P < .001), forward flexion (d = 0.50, P = .009), external rotation (d = 0.40, P < .001), function (d = 1.04, P < .001), and pain (d = -0.89, P < .001). CONCLUSION Patients with irreparable MRCT without presence of osteoarthritis have a high likelihood of achieving a painless shoulder and functional improvements after RSA.

Abstract
BACKGROUND Although some reports have presented short- to midterm results after arthroscopic repair of isolated subscapularis (SSC) tendon tears, long-term evaluation is still lacking. HYPOTHESIS Long-term results after arthroscopic repair of isolated SSC tears are comparable with the functional and radiological short- to midterm outcomes described in the literature. STUDY DESIGN Case series, Level of evidence, 4. METHODS This study assessed 17 patients (5 females and 12 males; mean age, 45.6 years) with isolated SSC tears (Fox and Romeo classification types 2-4) who underwent all-arthroscopic suture anchor repair. The mean interval from symptom onset to the time of surgery was 5.3 months in 16 patients (94.1%). One patient (5.9%) was symptomatic for a prolonged period (104 months) before surgery. All patients were assessed with a clinical examination preoperatively. SSC function was investigated using specific clinical tests and common scoring systems, including Constant, American Shoulder and Elbow Surgeons (ASES), Disabilities of the Arm, Shoulder and Hand (DASH), and Simple Shoulder Test (SST) scores. At follow-up, muscular strength was evaluated using an electronic force-measuring plate. Structural integrity of the repair was assessed using magnetic resonance imaging (MRI). RESULTS At a mean follow-up of 98.4 ± 19.9 months, the mean Constant score improved from 47.8 preoperatively to 74.2 postoperatively ( P = .001). Higher Constant ( P = .010) and ASES ( P = .001) scores were significantly associated with a shorter time from symptom onset to surgery. The size of the SSC lesion did not correlate with any clinical score outcome ( P = .476, .449, .985, and .823 for Constant, ASES, DASH, and SST scores, respectively). Three patients (17.6%) had persistent positive clinical test results (belly-press/lift-off). Compared with the uninjured contralateral side, SSC strength was significantly reduced in the belly-press position ( P = .031), although active internal ( P = .085) and external ( P = .093) rotation was not affected. In 1 patient, a rerupture was detected by MRI. Six patients had cranial SSC atrophy. Overall, 88.2% of patients were "very satisfied" or "satisfied" with their results. CONCLUSION Arthroscopic repair of isolated SSC tears results in significant clinical improvements and enduring tendon integrity, although SSC strength remains reduced in the long term. Early surgical treatment seems to be a relevant factor allowing good shoulder function.

Abstract
PURPOSE Subscapularis tendon ruptures, which are small in size, can be missed on CT or MRI imaging and are also difficult to diagnose by arthroscopy. Here we discuss a new sign of biceps tendon, which may point towards rupture of the subscapularis tendon. The biceps tendon may have scuffing, abrasion or partial tear of its anterior portion. We have named this as sentinel sign as it signals the presence of a coexisting subscapularis rupture. MATERIALS AND METHODS This study was a retrospective analysis of available arthroscopic rotator cuff repair surgery videos of 2009-2010. The videos were studied, and data recorded for number of cases showing the presence of sentinel sign and coexisting subscapularis rupture. Sensitivity, positive predictive value of the sign, was calculated. RESULTS Out of 330 available videos, 79 showed the presence of subscapularis rupture. Ten patients had a positive sentinel sign, but an intact biceps pulley that obscured the visualisation of the subscapularis tendon tear. This tear became apparent after removal of anterior part of biceps sling. CONCLUSION The presence of sentinel sign of the biceps tendon indicates the presence of a coexistent subscapularis rupture. If the rupture is not apparent, obscuring parts of the biceps sling should be removed to see the upper fibres of subscapularis tendon. LEVEL OF EVIDENCE Study of diagnostic test, Level III.

Abstract
BACKGROUND Traditional intra-articular arthroscopic repair techniques for massive anterosuperior rotator cuff tears are technically demanding and necessitate sacrifice of the rotator interval to enable visualization. An interval slide allows mobilization through release of the medial aspect of the rotator interval, while leaving the lateral, bridging fibers intact. QUESTIONS/PURPOSES The purpose of this study was to report a novel, arthroscopic, open-equivalent technique using the subdeltoid space to address these tears along with early clinical results. METHODS A retrospective review of prospectively collected data identified 11 consecutive arthroscopic massive anterosuperior rotator cuff repairs with a concomitant biceps tenodesis performed by the senior surgeon using a uniform technique. Outcome measures included range of motion, visual analog scale for pain, rotator cuff strength, American Shoulder and Elbow Surgeons (ASES) outcome scale, and Short Form-12 (SF-12). RESULTS Average length of follow-up was 22.2 months (range 12.5-30.0 months). Visual analog scale (VAS) pain scores, ASES, and SF-12 all demonstrated significant improvement from pre-op to final follow-up from 6.2 to 0.9 (p < 0.05), 27.4 to 82.8 (p < 0.05), and 26.6 to 45.5 (p < 0.05) respectively. Average forward flexion improved from 145° to 160° (p < 0.05). Seven of the nine patients with a positive preoperative belly press had a negative test at final follow-up. Nine of the 10 patients with a positive lift off test demonstrated a negative test on final follow-up. Ninety-one percent reported they were satisfied with their outcome. CONCLUSIONS The described modified all-arthroscopic subdeltoid approach for anterosuperior cuff repairs enabled an open-equivalent interval slide technique that preserved the bridging lateral fibers of the rotator interval and demonstrated promising early-term clinical results.

Recovery of subscapularis and shoulder function following arthroscopic treatment of isolated anterior and combined anterosuperior rotator cuff lesions. Arch Orthop Trauma Surg 2016; 136:75-81.

Abstract
BACKGROUND The purpose of the study was to evaluate the recovery of the subscapularis and shoulder function dependent on the type of lesion and type of surgical treatment, when compared to the non-affected contralateral shoulder. We hypothesized that regardless of type of lesion and performed surgical intervention, a significant muscle insufficiency as compared to the healthy contralateral side will remain. PATIENTS AND METHODS Sixty-eight patients (14 females and 54 males) with an anterior or anterosuperior cuff lesion at an average age of 55.7 ± 11.7 years (range 20-80 years) were prospectively evaluated up to 24 months. Intraoperatively, the lesions were classified according to current systems and treated by debridement or reconstruction. Pre- and postoperatively, the Constant Score (CS) as well as the belly-press angle (BPA) and back-to-hand distance (BHD) on the affected and on the contralateral shoulder was noted. RESULTS 29.4% had an isolated subscapularis lesion whereas 69.1% had concomitant supraspinatus pathology. In 17 patients an arthroscopic debridement and in 51 patients an arthroscopic repair were performed. Postoperatively, all patients revealed a significant improvement of the CS, BPA and BHD (p < 0.05) independent of the type of lesion or the surgical intervention. However, reconstruction of the subscapularis tendon resulted in significant differences of CS, BPA and BHD (p < 0.05) compared to the contralateral shoulder. CONCLUSION Reconstruction of subscapularis lesions cannot provide full subscapularis function since a residual subscapularis insufficiency remains, other than in patients with small partial tears treated with debridement alone.

Abstract
Objective: To evaluate the Bear Hug maneuver for clinically diagnosing subscapularis tendon tears, and compare this with other maneuvers described previously (Lift-off, Napoleon and Belly Press). Methods: Forty-nine patients with rotator cuff injuries who had undergone arthroscopy to repair the injury and had previously been assessed using the semiological maneuvers mentioned above were evaluated. Results: The diagnostic values obtained for the Bear Hug test were as follows: sensitivity 75%, specificity 56%, positive predictive value 62%, negative predictive value 70% and accuracy 65%. Conclusion: The highest sensitivity and negative predictive value values were obtained with the Bear Hug test. The highest specificity value was seen with the Lift-off test. The Belly press test gave the greatest specificity, positive predictive and accuracy values.

Functional and structural comparisons of the arthroscopic knotless double-row suture bridge and single-row repair for anterosuperior rotator cuff tears. J Shoulder Elbow Surg 2015; 24:1544-54. [PMID: 25940379 DOI: 10.1016/j.jse.2015.03.015] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2014] [Revised: 03/02/2015] [Accepted: 03/07/2015] [Indexed: 02/01/2023]
Abstract
BACKGROUND We compared the outcomes of knotless double-row suture bridge and single-row repairs in patients undergoing arthroscopic repair for anterosuperior rotator cuff tears. METHODS We included 61 full-thickness anterosuperior rotator cuff tears treated by arthroscopic repair, namely, single-row repair (group 1: 25 shoulders; mean patient age, 64 years) and the knotless double-row suture bridge repair (group 2: 36 shoulders; mean patient age, 62 years). Preoperative and postoperative magnetic resonance imaging was performed for all shoulders. Clinical outcomes were evaluated for mean follow-up periods of 81 months (range, 72-96 months) in group 1 and 34 months (range, 24-42 months) in group 2, using the University of California, Los Angeles and Japanese Orthopaedic Association assessments. RESULTS At the final follow-up, both groups showed improvement in the average University of California, Los Angeles and Japanese Orthopaedic Association scores and range of motion, although no intergroup differences were observed. Both groups showed improved abduction strength, and the average score was higher in group 2 (P = .0112). The lift-off and belly-press test results were improved in both groups. Postoperatively, the incidence of positive lift-off tests tended to be lower (P = .075) and that of positive belly-press tests was lower in group 2, P = .049). The repair failure rate tended to be lower in group 2 (14% [5 of 36]) than in group 1 (32% [8 of 25]; P = .0839). CONCLUSIONS Arthroscopic knotless double-row suture bridge repair of anterosuperior rotator cuff tears yielded functional outcomes equivalent to those of single-row repair and may be useful for improving subscapularis function, abduction strength, and tendon healing.

Abstract
A 13-year-old right-hand-dominant skeletally immature boy presented to the authors' clinic after being blocked during an overhead dodgeball throw and hearing an abrupt "pop" in the shoulder. He had pain in the subdeltoid region that was most prominent during sports-related activity, particularly throwing. The patient had nonoperative management of a lesser tuberosity avulsion fracture 1 year earlier after a similar injury that occurred during a basketball game. He had returned to normal sporting activity 2 months before the most recent injury. Repeat advanced imaging showed an avulsion fracture of the subscapularis tendon, with a significantly retracted 2-cm component as well as a less retracted component, suggesting acute-on-chronic injury. Given this retraction and the symptoms during throwing, the patient was counseled that surgical management would best facilitate an asymptomatic return to sports-related activity. This case showed acute-on-chronic subscapularis tendon insufficiency with avulsion of the lesser tuberosity and significant retraction of the subscapularis tendon without tearing, a rare injury pattern in adolescents. For fixation of the avulsed lesser tuberosity fracture, an open approach technique was used in which SpeedBridge (Arthrex, Naples, Florida) sutures were passed behind the bone fragment. Four anchors were placed medial and lateral to the subscapularis insertion points to create a knotless double-row footprint. Compared with the published literature, this method of subscapularis fixation offered secure anatomic repair in a time-efficient, user-friendly manner.

Abstract
INTRODUCTION Anterosuperior (AS) rotator cuff tear describes a combined tear of the subscapularis and the supraspinatus tendons. We hypothesized that results after AS tendon repairs might be influenced by the size of the subscapularis rupture and the preoperative subscapularis muscle fatty infiltration. METHODS A prospective multicentric study of 53 AS rotator cuff tears from five centers was performed (January 2008-January 2009). Subscapularis tendon retraction and fatty infiltration were assessed preoperatively. An ultrasonographic healing control was performed 1 year after surgery. RESULTS Patients were on average 60 years (range, 43-75 years) and were operated on average 16 months (range, 2-72 months) after the beginning of their symptoms. The incidence of AS tears was found to be 18%. Average follow-up was 15 months (range, 12-24). The Constant-Murley (CM) score for the patients with AS ruptures improved significantly from 49 points (range, 35-51 points) preoperatively to 73 points postoperatively (range, 50-95 points)(P=0.0205). CM score gains were 26 for Lafosse group 1 ruptures and 29 for Lafosse group 2 & 3 with pre- and postoperative P values at P<0.0000001 and P<0.000001, respectively. The last follow-up CM score according to the subscapularis fatty infiltration was 70 (range, 48-95) for groups 0-1, 70 (range, 56-87) for group 2, and 56 (range, 53-88) for groups 3-4 with pre- and postoperative P values at P<0.001, P<0.001, and P<0.004, respectively. The global retear rate was 6%. DISCUSSION Our study showed that the CM score after repairs of AS rotator cuff tears was lower in advanced subscapularis fatty infiltration. However, gains in CM scores were similar whatever the initial subscapularis fatty infiltration. The rate of tendon healing was correlated with subscapularis fatty infiltration. Subscapularis tendon rupture size was not significantly correlated with outcomes. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND As for the surgical treatment of the rotator cuff tears, the subscapularis tendon tears have recently received much attention for the mini-open or arthroscopic repair. The results of surgical repair for the subscapularis tendon tear are satisfactory, but the range of external rotation is reported to be restricted after the repair. The purpose of this study was to evaluate the range of glenohumeral joint motion after repairs of various sizes of subscapularis tendon tears. METHODS Using eight fresh frozen human cadaveric shoulders (mean age at death, 81.5 years), three sizes of subscapularis tendon tear (small, medium, and large) were made and then repaired. With the scapula fixed to the wooden jig, the end-range of glenohumeral motion was measured with passive movement applied through 1.0-Nm torque in the directions of scapular elevation, flexion, abduction, extension, horizontal abduction, and horizontal adduction. The passive end-ranges of external and internal rotation in various positions with rotational torque of 1.0 Nm were also measured. Differences in the ranges among the three type tears were analyzed. RESULTS As tear size increased, range of glenohumeral motion in horizontal abduction after repair decreased gradually and was significantly decreased with the large size tear (P < 0.01). The end-range of external rotation decreased progressively with increasing tear size in every glenohumeral position. The prominent decrease in external rotation (around 40° reduction from intact shoulders) was observed in shoulders after repair of large size tear at 30° to 60° of scapular elevation and abduction. CONCLUSIONS As the size of the subscapularis tendon tear increased, the passive ranges of horizontal abduction and external rotation of the glenohumeral joint after repair decreased significantly. In shoulders with a subscapularis tendon tear, it is necessary to consider the reduction of external rotation depending on tear size.

Abstract
This study evaluated pre- and postoperative clinical and structural outcome data on anterosuperior rotator cuff tears involving the supraspinatus and subscapularis treated by arthroscopic methods. Between June 2006 and October 2007, a total of 155 consecutive patients underwent an arthroscopic repair for a supraspinatus or supraspinatus and infraspinatus (superior) rotator cuff tear. Of these, 44 (28%) were identified on preoperative imaging to have involvement of the subscapularis. Confirmation of subscapularis tears occurred during arthroscopic repair of the superior rotator cuff. If the subscapularis was found to be torn, it was documented, and an arthroscopic repair was performed. Postoperative clinical and radiographic outcomes were assessed with the belly press and lift-off tests, range of motion, strength, pain score, Constant score, and either a magnetic resonance imaging arthrogram or a computed tomography arthrogram at an average of 15 months postoperatively. Failure was determined based on rotator cuff integrity on radiologic studies. Sixteen of the 44 anterosuperior rotator cuff tears identified on preoperative imaging were found to have a full-thickness subscapularis tear requiring repair on arthroscopic examination. On preoperative imaging, subscapularis tears were all either grade 1 or grade 2 (no complete grade 3 tears). Mean follow-up was 16.9 months (range, 13-24 months). Compared with preoperative values, significant postoperative improvements occurred in Constant scores, forward flexion, strength, and pain scores (P<.01). Patients also showed significant improvements in both the lift-off and belly press tests (P<.001). Mean postoperative patient satisfaction was 7.9 (range, 5-10) with 10 (59%) of 17 patients being extremely satisfied. Two of the 17 patients with an anterosuperior rotator cuff tear had confirmed retears of the supraspinatus (1 partial and 1 full-thickness) with no radiographic evidence of retear of any of the subscapularis repairs at most recent follow-up.

Abstract
Aims We performed a systematic review of the literature to determine
whether earlier surgical repair of acute rotator cuff tear (ARCT)
leads to superior post-operative clinical outcomes. Methods The MEDLINE, Embase, CINAHL, Web of Science, Cochrane Libraries,
controlled-trials.com and clinicaltrials.gov databases were searched
using the terms: ‘rotator cuff’, or ‘supraspinatus’, or ‘infraspinatus’,
or ‘teres minor’, or ‘subscapularis’ AND ‘surgery’ or ‘repair’.
This gave a total of 15 833 articles. After deletion of duplicates
and the review of abstracts and full texts by two independent assessors,
15 studies reporting time to surgery for ARCT repair were included.
Studies were grouped based on time to surgery < 3 months (group
A, seven studies), or > 3 months (group B, eight studies). Weighted
means were calculated and compared using Student’s t-test. Results Group B had a significantly higher pre-operative Constant score
(CS) (p < 0.001), range of movement in external rotation (p =
0.003) and abduction (p < 0.001) compared with group A. Both
groups showed clinical improvement with surgical repair; group A
had a significantly improved Constant score, University of California,
Los Angeles (UCLA) shoulder score, abduction and elevation post-operatively
(all p < 0.001). Group B had significantly improved Constant
score (p < 0.001) and external rotation (p < 0.001) post-operatively.
The mean Constant score improved by 33.5 for group A and by 27.5
for group B. Conclusion These findings should be interpreted with caution due to limitations
and bias inherent to case-series. We suggest a trend that earlier
time to surgery may be linked to better Constant score, and active
range of movement in abduction and elevation. Additional prospective
studies are required.

Abstract
PURPOSE The purpose of this study was to evaluate the clinical outcome of all-arthroscopic repair of degenerative subscapularis tendon tears and post-operative structural integrity using magnetic resonance imaging with a short-term follow-up. METHODS Twenty-one patients were treated all-arthroscopically for a full-thickness degenerative subscapularis tendon tear. Median patient age was 55 years (range, 41-69). Median follow-up was 25 months (range, 15-44). Patients were evaluated prior to surgery and at follow-up: active range of motion, VAS pain, Simple Shoulder Test (SST), and the Disabilities of the Arm, Shoulder, and Hand score (DASH). At final follow-up, the Constant-Murley score was evaluated. RESULTS Mean active range of motion showed significant post-operative improvement (p < 0.001). VAS pain improved from 8.3 (SD ± 1.3) pre-operatively to 2.7 (SD ± 1.8) post-operatively (<0.001); SST increased from 20 % (SD ± 26) pre-operatively to 83 % (SD ± 27) post-operatively (<0.001); DASH scores improved 67 (SD ± 19) to 18 (SD ± 21) post-operatively (<0.001). Post-operative Constant-Murley score was 79 (SD ± 12). Two patients had failure of the repair on post-operative MRI. Twelve cases (57 %) showed post-operative progression of fatty muscle infiltration. CONCLUSION All-arthroscopic repair is an effective treatment modality for degenerative subscapularis tendon tears with an anterosuperior tear pattern with good clinical results and high patient satisfaction. Although there was a high tendon-to-bone healing rate, fatty muscle infiltration was progressive in more than half of the patients. LEVEL OF EVIDENCE Therapeutic case series, Level IV.

Abstract
INTRODUCTION The purpose of this study was to determine the role of the subscapularis (SSC) in forward flexion. We hypothesized that the inferior part of the SSC has a main role in the ability to preserve forward flexion in cases of anterosuperior rotator cuff tears. MATERIAL AND METHODS Active forward flexion of the shoulder was prospectively evaluated in patients presenting with Grade 3 or higher SSC fatty degeneration, with superior and inferior SSC tears being evaluated separately. RESULTS Thirty-two patients were enrolled in this study. Pseudoparalytic shoulders were found in 80% of cases when the inferior part of the SSC was torn, but never when only the superior part was torn. DISCUSSION The inferior SSC or "Subscapularis minor" can be considered as an analogue to the teres minor in the posterior aspect of the shoulder. It must be preserved in cases of tears and fatty degeneration of the superior part, and repaired when possible. LEVEL OF EVIDENCE Level II.

Abstract
BACKGROUND In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the "bridging sign", which has not been previously described. PURPOSE To describe the "bridging sign" on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear. MATERIAL AND METHODS Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled. The medical records of the 29 patients were retrospectively reviewed for the duration of shoulder pain, rotator cuff tears, and associated arthroscopic findings: biceps tendon abnormality and superior glenoid labral tear. Then, preoperative shoulder MR images were retrospectively reviewed for the presence or absence of the "bridging sign" and associated MR findings: periarticular fluid and fatty atrophy of the supraspinatus and subscapularis muscles. The type of rotator cuff tear associated with the "bridging sign" was assessed and the sensitivity, specificity, and accuracy of the "bridging sign" for the diagnosis of a certain type of rotator cuff tear were calculated. Associated arthroscopic and MR findings and mean duration of the shoulder pain between the patients with and without the "bridging sign" were compared. RESULTS The "bridging sign" was seen in 17 of 29 patients and corresponded to a complex of the torn and superomedially retracted subscapularis tendon, coracohumeral ligament, and superior glenohumeral ligament, adhered to the anterior margin of the torn supraspinatus (SSP) tendon on arthroscopy. All patients with the "bridging sign" had combined full-thickness tear (FTT) of the cranial 1/2 portion of the subscapularis tendon and anterior 1/2 portion of the SSP tendon. The sensitivity, specificity, and accuracy of the "bridging sign" for the diagnosis of combined FTTs of the SSC tendon and anterior portion of the SSP tendon were 81.0%, 100%, and 86.2%, respectively. The patients with the "bridging sign" had longer duration of shoulder pain and more frequent associated arthroscopic and MR findings than the patients without the "bridging sign". CONCLUSION The "bridging sign" is a highly specific finding for combined full-thickness tears of the subscapularis tendon and anterior portion of the supraspinatus tendon, associated with more chronic shoulder pain and more sever rotator cuff tear.

Abstract
BACKGROUND Until the introduction of arthroscopic-assisted surgery for rotator cuff repair, the frequency of subscapularis tears was underestimated. These tears remain challenging to treat even with arthroscopy. The absence of a specific classification system has hampered communication about the treatment and outcomes of the various types of subscapularis tears. The objective of this prospective multicentre study was to validate the relevance of arthroscopic subscapularis tendon repair based on an assessment of short-term outcomes according to the initial extent of the anatomic lesions. METHODS A prospective multicentre study sponsored by the French Society for Arthroscopy was conducted from March 2010 to January 2011 in 208 patients with subscapularis lesions that were either isolated or associated with limited anterosuperior tears. The Constant and UCLA scores were used to assess clinical outcomes. Anatomic and prognostic results were evaluated based on the physical examination, preoperative and postoperative imaging study findings, and anatomic lesions. Clinical data were available for 103 patients after at least 1 year of follow-up and radiological data for 129 patients after at least 6 months. RESULTS The preliminary clinical results in 103 patients with at least 1 year of follow-up showed overall statistically significant improvements in the Constant and UCLA scores, with resolution of the clinical manifestations. The degree of improvement seemed to increase over time. The clinical results varied significantly across patient groups based on a classification system distinguishing four lesion types. Postoperative imaging studies to assess the anatomic results in all patients with at least 6 months of follow-up (n=129) showed tendon healing in 92% of cases but also indicated muscle wasting of the upper subscapularis muscle in 18.6% of cases and increased fatty degeneration of the muscle belly. DISCUSSION Our study confirms the good clinical and radiological results reported in the literature. Our classification system distinguishing four lesion patterns was applicable during the imaging workup. The main finding from this classification system was the difference in results between Type 2 and Type 3 lesions. The trend towards improvements over time requires confirmation by longer-term studies, which will also have to establish that the increased wasting of the upper subscapularis muscle and fatty degeneration of the muscle belly have no adverse effects.

Abstract
BACKGROUND The subscapularis is an important mover and stabilizer of the glenohumeral joint. Since the advent of shoulder arthroscopy, partial tears are found in 43% of rotator cuff patients. While partial tears to the upper band occur more commonly, little is known about the structure and mechanical behavior of the individual bands. Therefore, the objective of this study was to measure tensile mechanical properties, corresponding collagen fiber alignment, and histology in the upper and lower bands of the rat subscapularis tendon. MATERIALS AND METHODS Thirty adult Sprague-Dawley rats were euthanized and subscapularis tendons dissected out for mechanical organization (n = 24) and histologic assessment (n = 6). Collagen organization was measured with a custom device during mechanical testing. RESULTS Linear-region modulus at the insertion site was significantly lower in the upper band compared to the lower band, while no differences were found at the midsubstance location. The upper band was found to be significantly less aligned and demonstrated a more rounded cell shape than the lower band at the insertion site. DISCUSSION This study demonstrated that the 2 bands of the subscapularis tendon have differential mechanical, organizational, and histological properties, which suggests a functional deficit exists to the upper band of the subscapularis and may be contributing to the prevalence of partial subscapularis tears. CONCLUSIONS Clinicians should be aware that the upper band of the subscapularis tendon may be at higher risk of developing tears, based on decreased mechanical properties and a more disorganized collagen fiber distribution.

Arthroscopy 2012; 28:1592-600.

Abstract
PURPOSE To determine and propose a systematic approach to evaluating magnetic resonance imaging (MRI) scans for subscapularis tears and compares preoperative MRI interpretations with findings of the same shoulders at arthroscopy. METHODS The study was composed of 202 patients who underwent shoulder arthroscopy by 1 of 5 orthopaedic surgeons during a 3-month period. All patients had MRI scans performed within 6 months before arthroscopy. RESULTS Of the 202 patients, 82 had subscapularis tendon tears confirmed at the time of arthroscopy. The orthopaedic surgeons correctly diagnosed 60 of 82 patients (73%) with subscapularis tendon tears on preoperative MRI that were subsequently identified by arthroscopy. The orthopaedic surgeons correctly diagnosed 113 of 120 patients (94%) as not having subscapularis tendon tears. This resulted in an overall sensitivity of 73%, specificity of 94%, positive predictive value of 90%, negative predictive value of 84%, and accuracy of 86%. The frequency of subscapularis tears was highest when the long head of the biceps was displaced from the groove (88%), a combined supraspinatus/infraspinatus tear existed (71%), or the long head of the biceps tendon was torn (69%). CONCLUSIONS Preoperative MRI scans of the shoulder interpreted by orthopaedic surgeons with the described systematic approach resulted in improved accuracy in diagnosing subscapularis tendon tears compared with previous studies. A consistent finding is that larger subscapularis tendon tears are more easily detected using MRI scans whereas smaller tears are more frequently missed.

Does open repair of anterosuperior rotator cuff tear prevent muscular atrophy and fatty infiltration? Clin Orthop Relat Res 2012; 470:2776-84.

Abstract
BACKGROUND Repair of cuff tears involving rotator interval reportedly improves function. However, it is unclear whether successful repair prevents shoulder degenerative changes. QUESTIONS/PURPOSES Therefore, we (1) documented the minimal 4-year function of patients who underwent open surgical repair for rotator interval tears; (2) evaluated repaired tendon healing with postoperative MRI; and (3) sought to determine the influence of tendon healing on muscular and glenohumeral joint changes. METHODS We retrospectively analyzed 22 patients (23 shoulders) treated by open transosseous reinsertion of supraspinatus and subscapularis tendons. The mean age of the patients was 53 years (range, 37-64 years). The tear was traumatic in four cases. Repair healing and muscular changes were assessed using MRI. The minimum followup was 46 months (mean, 75 months; range, 46-103 months). RESULTS We observed an improvement in the absolute Constant-Murley score from 63 points preoperatively to 76 points postoperatively. With the last followup MRI, the supraspinatus tendon repair had failed in two of the 23 shoulders, whereas the subscapularis tendon repair had healed in all cases. Once healing of the repaired tendon occurred, supraspinatus muscle atrophy never worsened. However, on MRI fatty infiltration of the rotator cuff muscles increased despite successful tendon repair. Glenohumeral arthritis remained stable. Postoperative abduction and internal rotation strengths were better when the standardized supraspinatus muscle area was greater than 0.5 at the final evaluation. CONCLUSION Durable functional improvement and limited degenerative articular and muscular changes can be expected in most patients 4 to 10 years after open repair of anterosuperior cuff tears provided that healing of the cuff is obtained.

Abstract
PURPOSE Reports of the results of subscapularis repairs make up a very small minority of the published literature on rotator cuff repairs, yet subscapularis tears cause significant pain and dysfunction for patients. The goals of this study were to systematically review the published results after subscapularis repair and to compare arthroscopic versus open techniques when appropriate. METHODS The Cochrane, PubMed, and Embase databases were reviewed for studies evaluating isolated subscapularis repairs. If a study reported outcomes for both subscapularis and supraspinatus tears, a subgroup analysis of isolated subscapularis tears was necessary for inclusion in this review. Other inclusion criteria included a minimum of 1-year follow-up. RESULTS We found 3 arthroscopic repair studies and 6 open repair studies that met all inclusion criteria. The mean patient age was 49.2 years, and the mean time from injury to surgical repair was 11.1 months. Constant scores were consistent between groups, with a mean postoperative score of 88.1. Pain scores improved significantly after repair, with a mean of 13.4 (on a scale ranging from 0 to 15, with 15 being no pain) in the arthroscopic repair group and 11.5 in the open repair group. Concomitant procedures were common, with biceps tenodesis being the most common, having been performed in 54.8% of shoulders, followed by biceps tenotomy and biceps recentering. Healing was reported in 90% to 95% of shoulders. CONCLUSIONS Subscapularis tears can cause significant morbidity and often occur as traumatic injury in a younger population. Pain and function can be restored with repair, with excellent healing rates. The characteristic injury pattern suggested by a review of the literature is 1 where such tears are full thickness yet involve a portion of the tendon in the craniocaudal dimension. Concomitant procedures are common and can affect the results, because biceps tenotomy and tenodesis have been shown to significantly improve pain as well. All studies were Level IV, which introduced selection bias. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

Abstract
BACKGROUND Anterosuperior rotator cuff tears involving the subscapularis and supraspinatus tendons are less common than other tears of the rotator cuff. The purpose of this study was to report the clinical outcome, rotator cuff strength and structural integrity of open repair of combined anterosuperior rotator cuff tears. PATIENTS AND METHODS Forty-eight patients at an average age of 58 years underwent open repair of a combined supraspinatus and subscapularis tendon tear. The follow-up evaluation included clinical scores, rotator cuff strength testing with a custom-made force measurement plate (FMP) and postoperative MRI to evaluate repair integrity and muscle cross-sectional area. RESULTS After a mean follow-up of 49 months the average Constant score improved from 43 points preoperatively to 79 points postoperatively. The SST and the pain VAS were significantly improved by the procedure (each <0.05). The combined tear group with partial subscapularis tears (G1) did not achieve significantly better score results than the combined tear group with a full-thickness subscapularis tear (G2) (p > 0.05). Strength for all rotator cuff components was reduced significantly (p < 0.05) compared with the contralateral shoulder in both groups. MRI revealed a retear-rate of 4% for the subscapularis and a retear-rate of 19% for the supraspinatus. Postoperative muscle cross-sectional area of all rotator cuff muscles did not differ significantly between G1 and G2 (p > 0.05). CONCLUSION Open repair of combined anterosuperior rotator cuff tears achieved good postoperative results despite a residual rotator cuff strength deficit. Combined supraspinatus-/full-thickness subscapularis tears achieved equal clinical and radiographic results compared with supraspinatus-/partial-thickness subscapularis tears.

Abstract
The subscapularis is the largest and most powerful of the rotator cuff muscles and fulfills an important role in glenohumeral movement and stability. The spectrum and implications of subscapularis muscle or tendon injury differ from injury to other rotator cuff components because of its unique structure and function. Diagnosing subscapularis injury is clinically difficult and assessment of subscapularis integrity may be limited during arthroscopy or open surgery. Diagnostic imaging plays an important part in diagnosing and evaluating the extent of subscapularis injury. The radiologist should be aware of the anatomy of the subscapularis, the variations in muscle or tendon injury, and the potential implications for treatment and prognosis.

Abstract
The Latarjet procedure may be performed with both subscapularis splitting and subscapularis transecting approaches. The subscapularis splitting approach may better preserve subscapularis function and anatomy. The goal of this study was to determine the functional status of the subscapularis after the Latarjet procedure with a subscapularis splitting approach using the quantified belly press test. Thirty patients with traumatic anterior shoulder instability were prospectively enrolled in the study. All patients underwent a Latarjet procedure through a subscapularis splitting approach. Both operative and nonoperative extremities were tested preoperatively with a belly press test using an Isobex muscle strength analyzer (Medical Device Solutions AG, Oberburg, Switzerland). Fifteen patients returned for postoperative Isobex belly press testing at a minimum of 6 months. Average patient age was 23.3 years, and average follow-up interval was 13 months. We detected no significant differences in pre- vs postoperative subscapularis strength in the surgical shoulder (decreased by 0.3 kg [95% CI, -1.0 to 1.7 kg; P=.630]). There was no difference in control vs surgical arm at preoperative (control +0.3 kg stronger; 95% CI, -0.8 to 0.1 kg; P=.124) vs postoperative (control +0.3 kg stronger; 95% CI, -1.1 to 0.5 kg; P=.444) measurements. Neither sex (P=.593) nor surgery in the dominant arm (P=.459) had an effect on recovery of subscapularis strength. Finally, the surgical arm at follow-up was not significantly different from reported height- and weight-based normative values for either men (P=.481) or women (P=.298). This study suggests that subscapularis strength is not significantly altered by the Latarjet procedure with a subscapularis splitting approach.

Abstract
While uncommon, isolated avulsion fractures of the lesser trochanter occur in children and adolescents prior to the fusion of this apophysis as a result of athletic activities. In the elderly, isolated fractures of the lesser trochanter are rare but can occur as a result of trauma. They have been identified in patients with primary or secondary bone malignancies, which were previously considered pathognomonic for metastatic disease. In the absence of trauma, weakening of the bone due to systemic disorders such as osteoporosis or osteomalacia chronica renal failure may also be responsible. Diagnosis may be difficult with physical examination and radiographs alone. This case report details this rare fracture in 2 patients suffering from debilitating chronic disease. Patient 1 was a 30-year-old woman with an 18-year history of type 1 diabetes mellitus, a 6-year history of end-stage renal disease, hypertension, hypothyroidism, peripheral vascular disease, and a 3-year history of systemic lupus erythematosus with antiphospholipid syndrome treated with warfarin. Patient 2 was a 66-year-old woman with a history of type 2 diabetes mellitus, peripheral neuropathy, obesity, chronic obstructive pulmonary disease, gout, hypertension, and chronic neck and low back pain. Both were assessed with magnetic resonance imaging following physical examination, which revealed atraumatic avulsion of the distal iliopsoas tendon from the lesser trochanter. Following retraction of the iliopsoas tendon, the patients were treated with conservative therapy and anti-inflammatory medication. These 2 cases broaden the range of patients for whom spontaneous avulsion of the distal iliopsoas tendon should be considered in the differential diagnosis.

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
BACKGROUND Recently, a lesser tuberosity osteotomy has been promoted as an alternative to tenotomy for release of the subscapularis during shoulder arthroplasty. To our knowledge, no direct comparison of the clinical results of the two techniques has been presented. METHODS Thirty-five shoulders in thirty-four consecutive patients with osteoarthritis who had a primary total shoulder arthroplasty, performed with use of a standard subscapularis tenotomy (Group 1) or lesser tuberosity osteotomy (Group 2) to release the subscapularis, were evaluated retrospectively at an average of thirty-three months. Group 1 consisted of fifteen shoulders in fourteen patients (seven in males and eight in females, with an average age of sixty-seven years). Group 2 consisted of twenty shoulders in twenty patients (fourteen males and six females, with an average age of sixty-nine years). Assessment included a physical examination, clinical outcome questionnaires, conventional radiography, ultrasound examination of the subscapularis, and measurement of internal rotation strength. RESULTS The postoperative total Penn Shoulder Scores improved significantly from the preoperative levels in both groups (mean and standard deviation, 29 +/- 15 points to 81 +/- 20 points [p < 0.00001] in Group 1 and 29 +/- 16 points to 92 +/- 11 points [p < 0.00001] in Group 2). However, the postoperative mean total Penn Shoulder Score was higher in Group 2 (92 +/- 11 points) than in Group 1 (81 +/- 20 points) (p = 0.04). At one year, an abnormal subscapularis on ultrasound was associated with a lower mean Penn Shoulder Score in Group 1 (73 +/- 19 points compared with 92 +/- 3 points; p = 0.01). However, at a minimum two-year follow-up, this difference was not significant (mean, 74 +/- 24 points and 86 +/- 15 points, respectively; p = 0.25). There were more abnormal subscapularis tendons in Group 1 (six attenuated tendons and one full-thickness tear) than in Group 2 (two attenuated tendons). Internal rotation strength did not differ between the groups when controlled for sex (mean, 117 +/- 8 N and 127 +/- 21 N for males in Group 1 and Group 2, respectively [p = 0.22] and 77 +/- 27 N and 101 +/- 26 N, respectively, for females [p = 0.1]). CONCLUSIONS Both techniques resulted in improved clinical outcome scores. The lesser tuberosity osteotomy resulted in higher clinical outcome scores, a lower rate of subscapularis tendon tears, and universal healing of the osteotomy. This technique offers a means by which the rate of postoperative subscapularis tears may be reduced in patients undergoing total shoulder arthroplasty.

Abstract
Isolated avulsion fracture of the subscapularis from the lesser tuberosity of the humerus is rare in the pediatric population and only a couple of cases have been described in the literature. In our case, a 13-year-old young man suffered an avulsion of the subscapularis tendon from the lesser tuberosity of the humerus, accompanied by medial dislocation of the biceps tendon with degeneration and tear. The diagnosis was delayed until he completed several weeks of physical therapy. Special tests performed earlier in the primary care clinic or emergency department could have prevented prolonged symptoms and allowed earlier surgical intervention.

Abstract
PURPOSE The purpose of this study was to evaluate patients after an arthroscopic subscapularis tendon repair to determine their intermediate-term results. METHODS The records of all patients who underwent an arthroscopic rotator cuff repair by the senior author (S.S.B.) between January 1, 2000, and December 31, 2003, were reviewed. Patients were excluded from the study if their rotator cuff was repaired but there was not a subscapularis tear. Forty patients were included in this study. The median follow-up from the date of surgery to the last clinical evaluation was 5.0 years (range, 3.2 to 7.1 years). All patients had a complete history, physical examination, and plain radiographs of their shoulders. Both the modified University of California at Los Angeles (UCLA) and American Shoulder and Elbow Society (ASES) scores were calculated. RESULTS The visual analog scale for pain (mean +/- standard deviation) improved significantly (P < .001) from 6.1 +/- 2.4 preoperatively to 0.9 +/- 1.4 at the latest clinical follow-up evaluation; similarly, the mean modified ASES score improved significantly (P < .001) from 40.5 +/- 15.7 preoperatively to 91.2 +/- 12.7, and the mean modified UCLA score improved significantly (P < .001) from 15.7 +/- 4.2 preoperatively to 31.6 +/- 4.8. According to the UCLA scoring system, there were 18 excellent, 14 good, 6 fair, and 2 poor results. Eighty-three percent of patients returned to their usual work, sport, or hobbies after the operation. CONCLUSIONS At a median follow-up of 5 years, 80% (32 of 40) of patients had a good or excellent result after an arthroscopic subscapularis tendon repair. Eighty-eight percent of patients were satisfied with their shoulders at the latest follow-up evaluation. We conclude that the intermediate-term results show that arthroscopic subscapularis tendon repairs remain a good option for the treatment of patients with subscapularis tendon tears.

Abstract
PURPOSE The purpose of this study was to clarify anatomically and clinically how the subscapularis tendon supports the superior portion of the biceps tendon to the intertubercular groove. METHODS Thirty-three embalmed shoulder girdles were examined to investigate the subscapularis tendon and the pathway of the biceps tendon. In addition, operation records of 435 consecutive arthroscopic rotator cuff repairs were retrospectively reviewed. RESULTS Anatomically, the superior-most insertion of the subscapularis tendon was located on the upper margin of the lesser tuberosity. In addition, a thin tendinous slip extended from the insertion and attached to the fovea capitis of the humerus. The insertion, the tendinous slip, and the lateral portion of the cranial part of intramuscular tendons were in direct contact with the inferior side of the biceps tendon at its corner portion. The clinical study showed that 27.4% of rotator cuff tears (119/435) had subscapularis tendon tears. In cases with an unstable biceps tendon there was no intact subscapularis tendon. The superior-most insertion of the subscapularis tendon was involved in all transverse tears. Of 29 full-thickness transverse tears, 13 (44.8%) showed intra-articular dislocation. CONCLUSIONS The trochlea-like structure was composed of the superior-most insertion, the tendinous slip, and the lateral portion of the cranial part of intramuscular tendons supporting the biceps tendon. The transverse tear of the subscapularis tendon, which included this trochlea-like structure, often leads to intra-articular dislocation of the biceps tendon. CLINICAL RELEVANCE Instability of the biceps tendon should be carefully assessed because it is associated with subscapularis tendon tears at a very high incidence. When we repair a transverse tear of the subscapularis tendon, we should widely fix sufficiently strong tissue to support the biceps tendon on the uppermost margin, not on the anteromedial portion, of the lesser tuberosity.

Abstract
BACKGROUND Anterosuperior rotator cuff tears involving the subscapularis and supraspinatus tendons are less common than posterosuperior tears and are rarely discussed in the literature. The purpose of this study was to identify the unique features of this injury and to assess the outcome of operative treatment. METHODS Thirty consecutive patients, with a mean age of fifty-seven years (range, forty-three to seventy-three years), had an open repair of a traumatic anterosuperior rotator cuff tear. Twenty-four patients (80%) were male. Sixteen patients (53%) had involvement of the dominant shoulder, twenty-three (77%) had a biceps tendon disorder, and sixteen (53%) had a positive lift-off maneuver prior to surgery. Surgical approaches included an isolated superior deltoid-splitting approach in twenty patients, an isolated deltopectoral approach in five patients, and a combined approach in five patients. Open repair was performed at a mean of 4.5 months after the injury or the onset of symptoms. The final outcomes were determined with a physical examination and patient self-assessed outcome tools. RESULTS At a mean follow-up of fifty-six months, twenty-one of the thirty patients were satisfied with their symptoms, and twenty-nine would have the surgery again. The mean pain score on the visual analog scale improved from 6.2 to 1.2 (p < 0.001). The mean score on the Disabilities of the Arm, Shoulder and Hand questionnaire improved from 41.7 to 12.2 (p < 0.001). The mean percentage of functions that patients were able to perform on the Simple Shoulder Test improved from 36.4% to 82.8% (p < 0.001). The mean age and sex-adjusted Constant score was 93.4 postoperatively. The mean elevation, external rotation, and internal rotation of the involved shoulders were 97%, 109%, and 97%, respectively, of those of the contralateral side. The mean strength of elevation, external rotation, and internal rotation were 85%, 93%, and 101%, respectively, of those of the contralateral side. Infraspinatus involvement (p = 0.04), the extent of the supraspinatus tear (p = 0.03), and a Workers' Compensation claim (p = 0.03) were associated with worse outcomes and decreased satisfaction. CONCLUSIONS Patients with a traumatic anterosuperior rotator cuff tear present with internal rotation weakness, and they usually have a biceps tendon disorder. While larger tears involving greater portions of the supraspinatus and extending into the infraspinatus are associated with poorer outcomes, early recognition of this injury and open repair can reliably restore shoulder function to near normal levels.

Abstract
Transfer of pectoralis major has evolved as the most favoured option for the management of the difficult problem of irreparable tears of subscapularis. We describe our experience with this technique in 30 patients divided into three groups. Group I comprised 11 patients with a failed procedure for instability of the shoulder, group II included eight with a failed shoulder replacement and group III, 11 with a massive tear of the rotator cuff. All underwent transfer of the sternal head of pectoralis major to restore the function of subscapularis. At the latest follow-up pain had improved in seven of the 11 patients in groups I and III, but in only one of eight in group II. The subjective shoulder score improved in seven patients in group I, in one in group II and in six in group III. The mean Constant score improved from 40.9 points (28 to 50) in group I, 32.9 (17 to 47) in group II and 28.7 (20 to 42) in group III pre-operatively to 60.8 (28 to 89), 41.9 (24 to 73) and 52.3 (24 to 78), respectively. Failure of the tendon transfer was highest in group II and was associated with pre-operative anterior subluxation of the humeral head. We conclude that in patients with irreparable rupture of subscapularis after shoulder replacement there is a high risk of failure of transfer of p?ctoralis major, particularly if there is pre-operative anterior subluxation of the humeral head.
