Abstract
INTRODUCTION AND IMPORTANCE Repairing massive rotator cuff tears (MRCTs) can often be technically challenging due to tendon retraction, bursal fibrosis, and muscular fatty infiltration that usually occurs, often resulting in poor outcomes and an unpredictable prognosis. Although some other surgical management options have been reported, there is a lack of literature supporting tendon transfers in the presence of combined anterior and posterior-superior irreparable rotator cuff tears. We describe a case where a combined transfer of the latissimus dorsi and lower trapezius tendons was employed to treat an MRCT affecting the anterior and posterior superior portions of the rotator cuff. CASE PRESENTATION A 64-year-old male presented significant pain and limited range of motion in the right shoulder following a traumatic anterior shoulder dislocation seven months prior. MRI showed retracted tears (> 5 cm) of the supraspinatus, infraspinatus, and subscapularis tendons with significant fatty infiltration (Goutallier IV). The patient underwent an open transfer of the lower trapezius tendon to the greater tuberosity and the latissimus dorsi to the lesser tuberosity. At the final follow-up, 2.5 years postoperatively, the patient exhibited a painless functional range of motion and could resume daily activities. CLINICAL DISCUSSION Although there are alternative surgical options available, the positive outcomes observed in the presented case may be attributed to the restoration of rotational strength and the re-establishment of force coupling across the shoulder. CONCLUSION This report describes the successful implementation of a surgical treatment option for managing MRCT affecting the anterior and posterior superior portions of the rotator cuff.

Abstract
PURPOSE OF REVIEW Irreparable subscapularis tears, especially in younger patients with higher functional demands, present a challenging entity. Pectoralis major and latissimus dorsi tendon transfers are commonly considered for surgical management of this pathology, yet no consensus exists regarding the superior option. The purpose of this article is to review the most current tendon transfer techniques for irreparable subscapularis tears. RECENT FINDINGS For decades, transfer of the pectoralis major has been considered the gold standard technique for irreparable subscapularis tears. This transfer was found to reduce pain and improve functional outcome scores, yet range of motion and force of internal rotation were not maintained in long-term follow-up studies. The latissimus dorsi tendon transfer for the same indications has demonstrated biomechanical superiority in recent cadaveric studies with promising short-term results clinically. Both pectoralis major and latissimus dorsi tendon transfers improve outcomes of patients with irreparable subscapularis tears. Future comparative studies are still needed to determine superiority amongst techniques.

Anterior Latissimus Dorsi Transfer for Irreparable Subscapularis Tears Improves Shoulder Kinematics in a Dynamic Biomechanical Cadaveric Shoulder Model. Am J Sports Med 2024; 52:624-630. [PMID: 38294257 PMCID: PMC10905977 DOI: 10.1177/03635465231223514] [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: 03/17/2023] [Accepted: 11/08/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND In young patients with irreparable subscapularis deficiency (SSC-D) and absence of severe osteoarthritis, anterior latissimus dorsi transfer (aLDT) has been proposed as a treatment option to restore the anteroposterior muscular force couple to regain sufficient shoulder function. However, evidence regarding the biomechanical effect of an aLDT on glenohumeral kinematics remains sparse. PURPOSE/HYPOTHESIS The purpose of this study was to investigate the effects of an aLDT on range of glenohumeral abduction motion, superior migration of the humeral head (SM), and cumulative deltoid force (cDF) in a simulated SSC-D model using a dynamic shoulder model. It was hypothesized that an aLDT would restore native shoulder kinematics by reestablishing the insufficient anteroposterior force couple. STUDY DESIGN Controlled laboratory study. METHODS Eight fresh-frozen cadaveric shoulders were tested using a validated shoulder simulator. Glenohumeral abduction angle (gAA), SM, and cDF were compared across 3 conditions: (1) native, (2) SSC-D, and (3) aLDT. gAA and SM were measured using 3-dimensional motion tracking, while cDF was recorded in real time during dynamic abduction motion by load cells connected to actuators. RESULTS The SSC-D significantly decreased gAA (Δ-9.8°; 95% CI, -14.1° to -5.5°; P < .001) and showed a significant increase in SM (Δ2.0 mm; 95% CI, 0.9 to 3.1 mm; P = .003), while cDF was similar (Δ7.8 N; 95% CI, -9.2 to 24.7 N; P = .586) when compared with the native state. Performing an aLDT resulted in a significantly increased gAA (Δ3.8°; 95% CI, 1.8° to 5.7°; P < .001), while cDF (Δ-36.1 N; 95% CI, -48.7 to -23.7 N; P < .001) was significantly reduced compared with the SSC-D. For the aLDT, no anterior subluxation was observed. However, the aLDT was not able to restore native gAA (Δ-6.1°; 95% CI, -8.9° to -3.2°; P < .001). CONCLUSION In this cadaveric study, performing an aLDT for an irreparable subscapularis insufficiency restored the anteroposterior force couple and prevented superior and anterior humeral head migration, thus improving glenohumeral kinematics. Furthermore, compensatory deltoid forces were reduced by performing an aLDT. CLINICAL RELEVANCE Given the favorable effect of the aLDT on shoulder kinematics in this dynamic shoulder model, performing an aLDT may be considered as a treatment option in patients with irreparable SSC-D.

Biomechanical comparison of combined latissimus dorsi and teres major tendon transfer vs. latissimus dorsi tendon transfer in shoulders with irreparable anterosuperior rotator cuff tears. J Shoulder Elbow Surg 2023; 32:703-712. [PMID: 36529382 DOI: 10.1016/j.jse.2022.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 10/26/2022] [Accepted: 11/10/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Irreparable anterosuperior rotator cuff tears (IASRCTs) can result in a gradual loss of active elevation and internal rotation, superior and anterior translation of the humeral head, and cuff tear arthropathy. Joint-preserving treatment options for IASRCTs in young and high-demand elderly patients remain a subject of ongoing debate. The aim of the study was to evaluate the biomechanical efficacy of the combined latissimus dorsi and teres major tendon (LDTM) transfer and compare it to an isolated latissimus dorsi (LD) transfer in a cadaveric IASRCT model. METHODS Eight cadaveric shoulders (mean age, 68.3 ± 5.2 years; range 58-71) were tested with a custom shoulder testing system. All specimens were tested at 0°, 30°, and 60° of glenohumeral abduction in the scapular plane under 4 conditions: (1) intact, (2) IASRCT, (3) combined LDTM transfer, and (4) isolated LD transfer. The superior and anteroinferior translation and subacromial contact pressure were measured. The effects of 3 different LD and LDTM muscle loading conditions were investigated to determine the effectiveness of the muscle transfer conditions. A linear mixed effect model was used for statistical analysis, followed by a Tukey post hoc test. RESULTS IASRCTs significantly increased superior translation, anteroinferior translation, and subacromial peak contact pressure. Combined LDTM transfer significantly decreased superior and anteroinferior translation compared with IASRCTs in all positions and muscle loadings. Isolated LD transfer did not significantly decrease superior (P > .115) and anteroinferior translation (P > .151) compared to IASRCT at any abduction and muscle loads except superior translation at 60° abduction and 90° of external rotation (ER) (P < .036). LDTM transfer also significantly decreased peak contact pressure from the IASRCT condition at every abduction angle (P < .046). However, isolated LD transfer significantly decreased subacromial peak contact pressure only at 30° abduction and 0° and 30° of ER with triple loading (P < .048), as well as at 60° abduction and 90° of ER (P < .003). CONCLUSIONS Combined LDTM transfer decreased superior translation, anteroinferior translation, and subacromial contact pressure compared with the IASRCT condition. Isolated LD transfer did not improve glenohumeral translation and subacromial contact pressure. Combined LDTM transfer may be a more reliable treatment option than isolated LD transfer in patients with an IASRCT.

Abstract
BACKGROUND Irreparable anterosuperior rotator cuff tears (IASRCTs) can result in loss of active elevation, loss of internal rotation, and pseudoparalysis. Joint-preserving treatment options for IASRCTs in young and high-demand elderly patients are limited. The purpose of this study was to evaluate the clinical and radiologic outcomes of combined anterior latissimus dorsi and teres major (aLDTM) tendon transfer in patients with IASRCTs without reconstruction of the superior rotator cuff and capsular portion. METHODS This retrospective study was conducted between 2015 and 2018. We included patients who underwent combined aLDTM tendon transfer for IASRCTs. Clinical outcomes included visual analog scale for pain, Constant score, American Shoulder and Elbow Surgeons score, University of California Los Angeles shoulder scores, activities of daily living requiring active internal rotation score, active range of motion, subscapularis-specific physical examination, and rate of return to work. Radiographic analyses included the assessment of acromiohumeral distance, Hamada grade for cuff tear arthropathy, rate of anterior glenohumeral subluxation reduction, and transferred tendon integrity at 2 years postoperatively. RESULTS The mean follow-up period was 38.1 ± 13.7 (range: 24-63) months. Of the patients, 30 (mean age: 64.1 years) met the study criteria. Postoperatively, mean Constant, American Shoulder and Elbow Surgeons, University of California Los Angeles, and activities of daily living requiring active internal rotation scores improved from 47.4 to 69.9 (P < .001), 44.9 to 79.2 (P < .001), 20.0 to 28.7 (P < .001), and 13.2 to 26.9 (P < .001), respectively. The mean active range of motion was significantly increased postoperatively for both forward elevation (P < .001) and internal rotation at the back (P < .001). Of the patients, 24 (83%) returned to their previous work. No significant progression of cuff tear arthropathy was observed at final follow-up (Hamada grade: preoperative 1.3 ± 0.5 to postoperative 1.5 ± 0.7; p=0.155). Fifteen of 30 patients (50%) restored the anterior glenohumeral subluxation that was apparent preoperatively. One patient presented with transient axillary nerve palsy after surgery. Two patients presented with partial nonretracted tears of the transferred tendon. CONCLUSION This minimum 2-year follow-up study demonstrated that combined aLDTM tendon transfer without reconstruction of the superior rotator cuff and capsular portion was a viable treatment option with favorable clinical and radiologic outcomes for patients with IASRCTs.

Abstract
Delayed treatment of shoulder instability results in bone loss requiring more-complicated surgery, in turn resulting in less-optimal outcomes. Similarly, delayed treatment of repairable rotator cuff tears results in irreparable tears requiring more-complicated surgery and resulting in less-optimal outcomes. Delayed treatment of shoulder pathology is a problem. Solutions include education and research investigation.

Abstract
BACKGROUND Latissimus dorsi transfer (LDT) and pectoralis major transfer (PMT) were developed to treat an irreparable subscapularis tendon tear (ISScT); however, the difference in their outcomes remains unclear. PURPOSE To systematically review and compare the outcomes of LDT and PMT for ISScT. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic review was performed through a comprehensive search of Embase, PubMed, and the Cochrane Library. Studies of LDT or PMT were included according to the inclusion and exclusion criteria. The primary outcome was the Constant-Murley score (CMS) at the final follow-up. Secondary outcomes included the subjective shoulder value (SSV), visual analog scale (VAS) score for pain, active shoulder range of motion, and the belly-press and lift-off tests. Postoperative failure and complication rates were the safety outcome measures. Outcomes were summarized into the LDT and PMT groups, and results were compared statistically (P < .05). RESULTS Twelve studies were included in this review: 184 shoulders from 9 studies for the PMT group and 85 shoulders from 3 studies for the LDT group. For the PMT and LDT groups, the mean ages were 58.9 and 55.1 years, respectively, and the mean follow-up was 66.9 and 17.4 months, respectively. Overall, the LDT and PMT groups improved in the primary outcome (CMS) and secondary outcomes (SSV, VAS, ROM, and belly-press and lift-off tests), with low rates of failure and complication. When compared with the PMT group, the LDT group showed more significant improvements in CMS (35.2 vs 24.7; P < .001), active forward flexion (44.3° vs 14.7°; P < .001), abduction (35.0° vs 17.6°; P < .002), and positive belly-press test rate (45% vs 27%; P < .001). No statistically significant difference was seen between the groups in postoperative failure rate, complication rate, mean improvement of active internal rotation, VAS, or SSV. CONCLUSION In general, LDT showed significantly better clinical outcomes postoperatively than did PMT. The available fair-quality evidence suggested that LDT might be a better choice for ISScT. Further evaluations on the relative benefits of the 2 surgical approaches are required, with more high-quality randomized controlled studies.

Abstract
Subscapularis (SSc) is the prime internal rotator of shoulder. It is the most powerful rotator cuff muscle, maintaining the anterior force couple of shoulder. The tears in SSc as any other rotator cuff muscles might result from a traumatic event or more commonly from intrinsic degeneration. With the advent and widespread use of shoulder arthroscopy, SSc tears, which were once considered as "forgotten or hidden lesions" are now being increasingly recognized. Isolated SSc tears are relatively rare. They occur in combinations. Clinically internal rotation can be near normal because of the compensation provided by other internal rotators. It is not uncommon for patients with SSc tear to be normal on routine physical examination. The Bear Hug test (BHT) has high sensitivity and accuracy in the diagnosis of SSc tear. The combined use of BHT with Belly Press Test has been found optimal for diagnosis. US is an accurate and reliable method for diagnosing SSc tears and outperformed MRI in diagnosing partial-thickness SSc tears. The MRI is currently the most advanced imaging available for diagnosis. The specificity is up to 100%. However, the sensitivity is between 36 and 40%. The earliest classification system for SSc tears was by Fox et al. The commonly used classification is by Lafosse et al. The recent system by Yoo et al. is based on the insertion of SSc. The comma sign is gaining importance not only in arthroscopic diagnosis but also in MRI identification and repair of SSc. The mode of management is mainly arthroscopic. The techniques of repair of SSc are continuously progressing. However, there is no clear consensus on the double vs single-row repairs, biceps tendon management, and the role of coracoplasty. Future research must focus on these areas. Reserve shoulder arthroplasty is reserved for salvage in older age groups. Tendon transfers are performed in young active individuals with irreparable tears.

Abstract
PURPOSE The purpose of this study is to report structural integrity and clinical outcomes of superior capsular reconstruction (SCR) using a 4- to 5-mm acellular dermal allograft combined with augmentation of the remaining rotator cuff to the graft. METHODS We prospectively recruited 21 patients with symptomatic irreparable rotator cuff tear who required SCR. At least 6 months after the SCR, we evaluated each patient's graft healing by magnetic resonance imaging (MRI). We also assessed the range of motion (ROM), strength for forward flexion and external rotation, visual analog scale for pain (PVAS), American Shoulder and Elbow Surgeon (ASES) score, and Constant score. At minimum of 1 year after the surgery, we evaluated the number of patients with minimal clinically important differences (MCIDs) for each score to compare patients with healed and unhealed grafts. RESULTS Postoperative MRI showed the grafts intact in 14 patients (66.7%). Among 7 patients with unhealed grafts, tears were observed in 3 patients (42.9%) on the glenoid side, 3 (42.9%) on the humeral side, and 1 (14.3%) on both sides. PVAS, ASES score, and the Constant score improved after surgery (4.0 to 0.7 for PVAS [P < .001], 55.5 to 87.0 for ASES score [P < .001], and 56.0 to 65.9 for Constant score [P = .007]). However, there were no differences in postoperative ROM and muscle strength compared to preoperative measurements. MCIDs were reached in 90.5% of patients (n = 19) for the PVAS and in 71.4% of patients (n = 15) for the ASES score. Only 33.3% of patients (n = 7) obtained MCIDs for the Constant score, and none of the patients with a graft tear obtained MCIDs in the Constant score (P = .047). CONCLUSION The graft complete healing rate was 66.7%, although pain relief and functional improvement were satisfactory regardless of graft structural integrity. However, muscle strength recovery was not optimal until 1 year after surgery. LEVEL OF EVIDENCE Level IV; case series.

Abstract
PURPOSE OF REVIEW Massive irreparable rotator cuff tears present a significant challenge to the orthopedic surgeon. No single treatment, particularly among joint-preserving options, has been shown to be superior. The purpose of this review is to discuss recent advances in the treatment of massive irreparable rotator cuff tears, including partial repair with and without graft augmentation, interposition grafts, superior capsule reconstruction, subacromial balloon spacers, tendon transfer, and reverse total shoulder arthroplasty. We will also offer guidance on surgical indications based on our clinical experience. RECENT FINDINGS Partial repair may offer reasonable clinical improvement for patients with lower preoperative function despite high re-tear rates. Additionally, several types of interposition grafts have shown promising short-term results and may outperform repair alone. Subacromial balloon spacers may lead to clinical improvement, especially in patients without glenohumeral osteoarthritis or pseudoparalysis, and recently received FDA approval for use in the USA. Superior capsule reconstruction is a technically demanding procedure that appears to produce excellent short-term results particularly when performed at high volume, but long-term studies in heterogeneous study groups are needed. Tendon transfers improve function by restoring force coupling in the shoulder, offering a promising option for younger patients. Reverse total shoulder arthroplasty (RTSA) is a reliable option for treatment of irreparable cuff tears in elderly patients with lower functional demands.
