Abstract
The optimal treatment for patients with posterior superior irreparable rotator cuff tears (PSIRCTs) is still a topic of ongoing debate. Lower trapezius tendon transfer is one of the effective surgical treatments for PSIRCTs in younger patients and elderly patients with high activity levels without arthritis. In this report, we describe an arthroscopic-assisted technique for lower trapezius transfer using a fascia lata autograft for patient with PSIRCTs in lateral decubitus position.

Abstract
Introduction Massive rotator cuff tears (MRCTs) have long posed a complex problem for both patients and surgeons. If not treated promptly, tendon retraction, fatty infiltration and muscle atrophy of the rotator cuff muscles occur. These lead to irreparable RCTs with poor functional outcomes. We describe our technique of superior capsular reconstruction (SCR) augmented with partial cuff repair and report on our short term outcomes. Method Seven consecutive patients who underwent the procedure were recruited at our institution from January 2019 to December 2019. Medical records of these patients were reviewed looking at pre-operative symptoms and examination findings, imaging studies, intra-operative findings, the surgical technique employed, post-operative progress in terms of pain, affected shoulder range of movement and outcome scores. Results All patients showed complete tears of at least two tendons and were deemed irreparable intra-operatively. All patients exhibited Goutalier grade 2-4 wasting of the affected tendons on MRI and Patte grade 3 intra-operatively. At 12 months, the mean improvement shown in Constant score is 12.1 points, in University of California Los Angeles (UCLA) score is 9.4 points and in Oxford Shoulder Score is 17 points. Active forward flexion improved in all patients with a mean improvement of 40 degrees. Numerical Pain Rating Scale improved in all patients with a mean of 5.1 points. Conclusion Our case series shows good short-term outcomes can be achieved with SCR augmented with partial cuff repair. Notably, our SCR results showed encouraging results even for challenging revision rotator cuff repairs.

Physiological Tensioning During Lower Trapezius Transfer for Irreparable Posterosuperior Rotator Cuff Tears May Be Important for Improvement in Shoulder Kinematics. Am J Sports Med 2023; 51:2422-2430. [PMID: 37318086 PMCID: PMC10353027 DOI: 10.1177/03635465231179693] [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: 08/18/2022] [Accepted: 04/28/2023] [Indexed: 06/16/2023]
Abstract
BACKGROUND Lower trapezius transfer (LTT) has been proposed for restoring the anteroposterior muscular force couple in the setting of an irreparable posterosuperior rotator cuff tear (PSRCT). Adequate graft tensioning during surgery may be a factor critical for sufficient restoration of shoulder kinematics and functional improvement. PURPOSE/HYPOTHESIS The purpose was to evaluate the effect of tensioning during LTT on glenohumeral kinematics using a dynamic shoulder model. It was hypothesized that LTT, while maintaining physiological tension on the lower trapezius muscle, would improve glenohumeral kinematics more effectively than undertensioned or overtensioned LTT. STUDY DESIGN Controlled laboratory study. METHODS A total of 10 fresh-frozen cadaveric shoulders were tested using a validated shoulder simulator. Glenohumeral abduction angle, superior migration of the humeral head, and cumulative deltoid force were compared across 5 conditions: (1) native, (2) irreparable PSRCT, (3) LTT with a 12-N load (undertensioned), (4) LTT with a 24-N load (physiologically tensioned according to the cross-sectional area ratio of the lower trapezius muscle), and (5) LTT with a 36-N load (overtensioned). Glenohumeral abduction angle and superior migration of the humeral head were measured using 3-dimensional motion tracking. Cumulative deltoid force was recorded in real time throughout dynamic abduction motion by load cells connected to actuators. RESULTS Physiologically tensioned (Δ13.1°), undertensioned (Δ7.3°), and overtensioned (Δ9.9°) LTT each significantly increased the glenohumeral abduction angle compared with the irreparable PSRCT (P < .001 for all). Physiologically tensioned LTT achieved a significantly greater glenohumeral abduction angle than undertensioned LTT (Δ5.9°; P < .001) or overtensioned LTT (Δ3.2°; P = .038). Superior migration of the humeral head was significantly decreased with LTT compared with the PSRCT, regardless of tensioning. Physiologically tensioned LTT resulted in significantly less superior migration of the humeral head compared with undertensioned LTT (Δ5.3 mm; P = .004). A significant decrease in cumulative deltoid force was only observed with physiologically tensioned LTT compared with the PSRCT (Δ-19.2 N; P = .044). However, compared with the native state, LTT did not completely restore glenohumeral kinematics, regardless of tensioning. CONCLUSION LTT was most effective in improving glenohumeral kinematics after an irreparable PSRCT when maintaining physiological tension on the lower trapezius muscle at time zero. However, LTT did not completely restore native glenohumeral kinematics, regardless of tensioning. CLINICAL RELEVANCE Tensioning during LTT for an irreparable PSRCT may be important to sufficiently improve glenohumeral kinematics and may be an intraoperatively modifiable key variable to ensure postoperative functional success.

Orthop J Sports Med 2023; 11:23259671231166703. [PMID: 37213659 PMCID: PMC10196541 DOI: 10.1177/23259671231166703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 02/06/2023] [Indexed: 05/23/2023] Open
Abstract
Background Arthroscopic superior capsular reconstruction (SCR) has been introduced as a successful alternative to latissimus dorsi tendon transfer (LDTT) for irreparable posterosuperior rotator cuff tears. Purpose To compare minimum 5-year clinical outcomes of SCR and LDTT for the treatment of irreparable posterosuperior rotator cuff tears in patients with minimal evidence of arthritis and intact or reparable subscapularis tears. Study Design Cohort study; Level of evidence, 3. Methods Patients who underwent SCR or LDTT and had undergone surgery ≥5 years earlier were included. The SCR technique used a dermal allograft customized to the defect. Surgical, demographic, and subjective data were collected prospectively and reviewed retrospectively. Patient-reported outcome (PRO) scores utilized were the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), the short version of the Disabilities of the Arm, Shoulder and Hand score (QuickDASH), 12-Item Short Form Health Survey Physical Component Summary (SF-12 PCS), and patient satisfaction. Further surgical procedures were documented, and treatment that progressed to reverse total shoulder arthroplasty (RTSA) or revision rotator cuff surgery was considered a failure. Kaplan-Meier survivorship analysis was performed. Results Thirty patients (n = 20 men; n = 10 women) with a mean follow-up of 6.3 years (range, 5-10.5 years) were included. A total of 13 patients underwent SCR and 17 patients underwent LDTT. The mean age of the SCR group was 56 years (range, 41.2-63.9 years), and the mean age of the LDTT group was 49 years (range, 34.7-57 years) (P = .006). One patient in the SCR group and 2 patients in the LDTT group progressed to RTSA. Two additional (11.8%) patients in the LDTT group had further surgery-1 had arthroscopic cuff repair and 1 had hardware removal with biopsies. The SCR group demonstrated significantly better ASES (94.1 ± 6.3 vs 72.3 ± 16.4; P = .001), SANE (85.6 ± 8 vs 48.7 ± 19.4; P = .001), QuickDASH (8.8 ± 8.7 vs 24.3 ± 16.5; P = .012), and SF-12 PCS (56.1 ± 2.3 vs 46.5 ± 6; P = .001) PROs at the final follow-up. There was no significant difference between groups in median satisfaction (SCR, 9; LDTT, 8 [P = .379]). At 5 years, survivorship rates were 91.7% and 81.3% for the SCR and LDTT groups, respectively (P = .421). Conclusion At the final follow-up, SCR yielded superior PROs compared with LDTT for the treatment of massive, irreparable posterosuperior rotator cuff tears despite similar patient satisfaction and survivorship between procedures.

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.

Effect of intraarticular pressure on glenohumeral kinematics during a simulated abduction motion: a cadaveric study. BMC Musculoskelet Disord 2023; 24:105. [PMID: 36750786 PMCID: PMC9906871 DOI: 10.1186/s12891-023-06127-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 01/02/2023] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND The current understanding of glenohumeral joint stability is defined by active restrictions and passive stabilizers including naturally-occurring negative intraarticular pressure. Cadaveric specimens have been used to evaluate the role of intraarticular pressure on joint stability, although, while the shoulder's negative intraarticular pressure is universally acknowledged, it has been inconsistently accounted for. HYPOTHESIS During continuous, passive humeral abduction, releasing the native intraarticular pressure increases joint translation, and restoring this pressure decreases joint translations. STUDY DESIGN Descriptive Laboratory Study. METHODS A validated shoulder testing system was used to passively abduct the humerus in the scapular plane and measure joint translations for seven (n = 7) cadaveric specimens. The pressure within the glenohumeral joint was measured via a 25-gauge needle during passive abduction of the arm, which was released and subsequently restored. During motion, the rotator cuff muscles were loaded using stepper motors in a force feedback loop and electromagnetic sensors were used to continuously measure the position of the humerus and scapula. Joint translation was defined according to the instant center of rotation of the glenohumeral head according to the recommendations by the International Society of Biomechanics. RESULTS Area under the translation versus abduction angle curve suggests that releasing the pressure within the capsule results in significantly less posterior translation of the glenohumeral head as compared to intact (85-90˚, p < 0.05). Posterior and superior translations were reduced after 70˚ of abduction when the pressure within the joint was restored. CONCLUSION With our testing system employing a smooth continuous passive motion, we were able to show that releasing intraarticular pressure does not have a major effect on the path of humeral head motion during glenohumeral abduction. However, both violating the capsule and restoring intraarticular pressure after releasing alter glenohumeral translations. Future studies should study the effect of simultaneous external rotation and abduction on the relationship between joint motion and IAP, especially in higher degrees of abduction. CLINICAL RELEVANCE Thoroughly simulating the glenohumeral joint environment in the cadaveric setting may strengthen the conclusions that can be translated from this setting to the clinic.

Abstract
Background Shoulder abduction is an essential movement for placement of the hand in space and thus for upper limb function. The objective of this study was to introduce and test the effectiveness of a new technique of latissimus dorsi tendon transfer to deltoid insertion to restore shoulder abduction. Methods We prospectively included 10 male patients with a lost deltoid function. Their mean age was 34.6 years (range, 25-46). We describe a new technique to compensate for the loss of the deltoid function using a latissimus dorsi tendon transfer augmented with a semitendinosus tendon graft. The tendon graft is passed over the acromion and attached to the anatomical deltoid insertion. Postoperatively, a shoulder spica in 90° abduction was used for six weeks followed by physiotherapy. Results Patients were followed up for a mean of 25.4 months (range, 12-48). The mean range of active shoulder abduction rose to 110° (range, 90-140°) with a mean gain of 83° of abduction. Conclusions This procedure can be a useful technique for restoration of a significant range and strength of active shoulder abduction.

Abstract
INTRODUCTION Latissimus dorsi and teres major (LDTM) tendon transfer has demonstrated better clinical outcomes compared to Latissimus dorsi (LD) transfer for irreparable anterosuperior cuff (subscapularis/supraspinatus) tears; however, the biomechanical effects of these procedures are unknown. Therefore, the objective of this study was to compare kinematics and internal rotation of LDTM transfer to LD transfer for anterosuperior cuff tear. METHODS Eight cadaveric shoulders were tested in four conditions; (1) intact, (2) anterosuperior rotator cuff tear, (3) LDTM transfer, and (4) LD transfer. Glenohumeral kinematics and internal rotation at 0°, 30°, and 60° of glenohumeral abduction in the scapular plane were measured. Muscle loading was applied based on physiological cross-sectional area ratios with three muscle loading conditions to simulate potentially increased tension due to the advanced insertion site of the transferred tendons. RESULTS The anterosuperior rotator cuff tear leads to a significant superior shift of the humeral head compared to intact at 0° and 30° abduction (p < 0.039). Both the LDTM (p < 0.047) and LD transfers (p < 0.032) significantly shifted the humeral head inferiorly compared to the tear condition.; however, the LDTM transfer shifted the head in the anteroinferior direction compared to the LD transfer at 60° abduction and 30° ER (p < 0.045). Both LDTM and LD transfer significantly increased internal resting rotation (p < 0.008) and maximum internal rotation (p < 0.008) compared to anterosuperior rotator cuff tear and intact at 30° and 60° abduction. LDTM transfer resulted in a significant internal resting rotation compared with the LD transfer at 30° abduction with double muscle loading (p = 0.02). At 0° abduction, the LDTM transfer (p < 0.027) significantly increased maximum internal rotation compared to anterosuperior rotator cuff tear and intact. CONCLUSION Although both LDTM and LD tendon transfer improved the abnormal humeral head apex position and internal rotation compared with the tear condition, the LDTM transfer was biomechanically superior to the LD transfer in a cadaveric model.

Abstract
BACKGROUND In the setting of irreparable posterosuperior rotator cuff tears (PSRCTs), lower trapezius transfer (LTT) may be anatomically better positioned for restoring the muscular force couple compared with latissimus dorsi transfer (LDT). The purpose of the study was to evaluate the effect of LTT and LDT on glenohumeral kinematics using a dynamic shoulder model. METHODS Ten fresh-frozen cadaveric shoulders (mean age: 56.5 ± 17.2 years) were tested using a dynamic shoulder simulator. The maximum abduction angle (MAA), superior humeral head migration (SHM), and cumulative deltoid forces (CDFs) were compared across 4 conditions: (1) native; (2) irreparable PSRCT; (3) LTT using an Achilles tendon allograft; and (4) LDT. MAA and SHM were measured using 3-dimensional motion tracking. CDF was recorded in real time throughout the dynamic abduction motion by load cells connected to actuators. RESULTS Compared to the native state, the PSRCT resulted in a significant decrease (Δ-24.1°; P < .001) in MAA, with a subsequent significant increase after LTT (Δ13.1°; P < .001) and LDT (Δ8.9°; P < .001). LTT achieved a significantly greater MAA than LDT (Δ4.2°; P = .004). Regarding SHM, both LTT (Δ-9.4 mm; P < .001) and LDT (Δ-5.0 mm; P = .008) demonstrated a significant decrease compared with the PSRCT state. LTT also achieved significantly less SHM compared with the LDT (Δ-4.4 mm; P = .011). Further, only the LTT resulted in a significant decrease in CDF compared with the PSRCT state (Δ-21.3 N; P = .048), whereas LTT and LDT showed similar CDF (Δ-11.3 N; P = .346). However, no technique was able to restore the MAA, SHM, and CDF of the native shoulder (P < .001, respectively). CONCLUSION LTT and LDT both achieved a significant increase in MAA along with significantly less SHM compared with the PSRCT state. Although LTT required significantly less compensatory deltoid forces compared with the PSRCT state, this was not observed for the LDT. Further, the LTT prevented loss of abduction motion and SHM more sufficiently. In the challenging treatment of irreparable PSRCTs, LTT may restore native glenohumeral kinematics more sufficiently, potentially leading to improved postoperative functional outcomes.

Abstract
BACKGROUND Latissimus dorsi transfer (LDT) and lower trapezius transfer (LTT) are effective treatment options for posterosuperior irreparable rotator cuff tears (IRCTs) in relatively young patients and elderly high-demand patients without arthritic changes. However, the optimal treatment option for patients with posterosuperior IRCT remains a subject of ongoing debate. This study aimed to compare clinical and radiologic short-term outcomes between arthroscopic-assisted LDT (aLDT) and arthroscopic-assisted LTT (aLTT) in patients with posterosuperior IRCT. METHODS This retrospective crossover study included patients who underwent aLDT or aLTT for posterosuperior IRCT and who had a minimum clinical follow-up time of 2 years after undergoing surgical procedures between January 2012 and June 2019. A total of 90 patients with posterosuperior IRCT were divided into 2 groups according to the surgical procedure: group D underwent aLDT (n = 48) and group T underwent aLTT (n = 42). Clinical outcomes comprised the visual analog scale score for pain, active shoulder range of motion (ROM), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, and activities of daily living that require active external rotation (ADLER) score. Radiologic outcomes included acromiohumeral distance (AHD). The progression of arthritis was evaluated using Hamada grade. Graft integrity was assessed using postoperative magnetic resonance imaging. RESULTS Significant improvements in clinical outcomes were observed in both groups. Active shoulder external rotation (P < .001), postoperative ASES score (P < .001), and ADLER score (P < .001) were significantly higher in group T than in group D. AHD at 2-year follow-up was significantly higher in group T than in group D (P < .001). The rate of progression of arthritis was significantly higher in group D (31.3%) than in group T (7.1%) (P = .031). CONCLUSIONS Although both LDT and LTT improved the overall clinical outcomes of patients with posterosuperior IRCT, LTT was superior to LDT in terms of shoulder ROM, functional improvement, and progression of arthritis. Our findings indicate that LTT may be the preferred treatment option for posterosuperior IRCT in relatively active and young patients.

Abstract
PURPOSE The purpose of this study was to evaluate clinical and radiologic outcomes of arthroscopic superior capsular reconstruction (ASCR) with fascia lata autograft in patients with irreparable rotator cuff tears (IRCTs) performed using a single lateral-row fixation technique. METHODS We studied a retrospective case series of patients with large or massive IRCTs for ASCR with fascia lata autograft. Clinical outcomes were evaluated using the Visual Analog Scale (VAS) and the Constant score. Healing of the graft was assessed by magntic resonance imaging or ultrasound. Acromiohumeral distance was evaluated by radiographs. RESULTS Thirty-one patients with an average age of 61 years and an average follow-up of 35 months (24-51 months) underwent ASCR with fascia lata autograft. There was a significant improvement in VAS (7.7-0.7), Constant score (36.0-78.7), forward elevation (115°-171°), external rotation (33°-50°), strength (0.3 kg-2.3 kg), and acromiohumeral distance (6.1 mm-8.6 mm) (P < 0.001). Graft failure was present in 13.8% of patients, as shown by magnetic resonance imaging (26 patients) or ultrasound (3 patients). Patients with failed ASCR showed worse Constant scores (68.5.8 vs 80.2, P = 0.007), worse VAS (2.5 vs 0.4, P = 0.00002), worse external rotation (20° vs 54°, P = 0.004), lower acromiohumeral distance (5mm vs 9mm, P = 0.007), and a high association with the presence of os acromiale (χ2P = 0.003). No revision or subsequent surgical procedures were required. CONCLUSIONS ASCR, with autologous fascia lata and single lateral row configuration, is an effective option in irreparable rotator cuff tears and results in clinical and radiologic improvement. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND The treatment of massive, irreparable rotator cuff tears remains controversial today because there is no consensus on the ideal treatment option. This investigation aimed to prospectively evaluate and compare the outcomes of arthroscopy-assisted latissimus dorsi transfer and superior capsular reconstruction in the treatment of massive, irreparable rotator cuff tears. METHODS Forty-two patients at an average age of 62.8 years with massive, irreparable rotator cuff tears were randomized into 2 treatment groups. Twenty-one patients underwent arthroscopy-assisted latissimus dorsi tendon transfer (LDT), and 21 patients underwent arthroscopy-assisted superior capsular reconstruction (SCR). The patients were followed up prospectively for 31 months on average. One patient in the SCR group was lost to follow-up. The outcomes were evaluated with American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Western Ontario Rotator Cuff Index (WORC), visual analog scale (VAS), and Constant scores clinically and with acromiohumeral distance (AHD) measurements radiologically. RESULTS Both groups displayed improved results in ASES, WORC, Constant, and VAS scores in the final follow-up (P < .001). The LDT group had significantly better results in AHD (P = .006), whereas the SCR group yielded significantly higher improvements in ASES (P = .007) and Constant (P = .008) scores. The rate of successful pseudoparalysis treatment was 45% (5/11) in the LDT group and 92% (12/13) in the SCR group (P = .011). The graft failure rate was 5% (1 patient) in each group postoperatively; 1 patient in the SCR group had a traumatic graft rupture and 1 patient in the LDT group was complicated with septic arthritis, which required graft removal. CONCLUSION Both SCR and LDT yielded promising short-term results in treatment of massive, irreparable rotator cuff tears in this study. The SCR group displayed better overall outcomes clinically, particularly in the pseudoparalytic shoulders, whereas the LDT group displayed better radiologic results.

Abstract
Background Previously reported outcomes after tendon transfers to reconstruct the subscapularis are unpredictable and often unsatisfactory, especially in the presence of anterior humeral head subluxation. We studied the anatomic feasibility of the lower trapezius and the rhomboid minor transfer to reconstruct irreparable tendon tears of the subscapularis. The aim of this study was to determine the feasibility of lower trapezius and rhomboid minor transfer to reconstruct irreparable subscapularis tendon tears. Materials and methods We measured the tendons dimensions, muscles excursions, distances to pedicles, and dissection needed to complete a successful lower trapezius and/or rhomboid minor transfer to the subscapularis footprint in 10 cadaveric shoulders. The transferred muscles were detached distally, augmented with a semitendinosus and gracilis autograft, and passed anteriorly between the scapula and the subscapularis remnant through a small serratus window to reach the lesser tuberosity. The risk of pedicle compression was subjectively assessed in all cases. Results The trapezius and rhomboid tendons were asymmetric with an average length of 37.6 mm and 21.7 mm, an average width of 63 mm and 33.4 mm, respectively. The mean distances from each distal insertion to the lesser tuberosity were 109 mm for the trapezius and 144 mm for the rhomboid. Mean distances from tendon to pedicle were 57.9 mm and 33.1 mm, respectively. The mean size of the necessary serratus window was 49.4 mm, which was measured at maximal excursion achieved at maximal external rotation 90° representing two digitations. All of the tendon transfers were feasible, and the risk of pedicle compression was 20% for the trapezius and 10% for the rhomboid. Superior migration of the transfer was observed during passive external rotation if the insertion point was too high. Conclusions Transfer of the lower trapezius and rhomboid minor to the lesser tuberosity to reconstruct an irreparable subscapularis tear is feasible without extensive dissection and with a low risk of nerve compression. We recommend not to transfer the rhomboid minor routinely, owing to the risk of tendon luxation after external rotation of the shoulder.

Abstract
Background and objectives: Massive rotator cuff tears compromise shoulder mobility function and cannot be directly repaired. Latissimus dorsi tendon transfer (LDTT) is a therapeutic alternative suitable for the treatment of rotator cuff tears that helps to restore external shoulder rotation. Cadaver models have been used for studying the effects of LDTT and procedural variations, but, to the best of our knowledge, none of them have been validated. The aim of our study was to validate a novel cadaver model while verifying the effects of LDTT on external rotation. Materials and Methods: Two groups were included in the study: a cadaver group and a control group made up of healthy volunteers, which were used for the validation of the cadaver model. Baseline external rotation measurements were performed with both groups, after which a massive rotator cuff tear was inflicted and repaired with LDTT in the cadaver group. Their postoperative external rotation was evaluated using three different tests. Results: No statistically significant differences were found between the baseline measurements of the two groups, and postoperative external rotation was significantly higher after LDTT in all cases but one. Conclusions: Cadaver models were validated, since they had a similar preoperative external rotation to healthy volunteers. Moreover, they allowed us to demonstrate the effect of LDTT on external shoulder rotation.

Abstract
PURPOSE Lower trapezius (LT) transfer using Achilles tendon allograft or semitendinosus autograft is effective in restoring external rotation in massive irreparable posterosuperior rotator cuff tears (RCT). The purpose of this study was to evaluate if the infraspinatus fascia (IF) could be used in LT transfer to extend the LT tendon. METHODS Eight fresh-frozen whole-body cadavers were dissected using both shoulders, beach chair position. A 2.5-3 cm wide bundle of the IF was dissected, from the inferior angle of the scapula up to the insertion of the LT which was then detached subperiosteally in continuity with the fascia. The extended tendon was reinforced with sutures and brought to the center of the footprint of the supraspinatus on the humerus. We measured: (a) the distance between the insertion of the LT on the scapula and the inferior angle of the scapula, estimating the length of the IF that can be harvested, (b) the distance between the insertion of the LT on the scapula and the center of footprint of the infrastinatus on the humerus, estimating the distance needed to be covered by the graft (c) the length of the extended tendon between the center of footprint of the infrastinatus on the humerus (fixation point) and its free end, estimating the length available for fixation. RESULTS The mean length of the fascia that can be harvested is 125.56 mm. The mean distance that needs to be covered by the graft is 100 mm. The extended tendon is long enough leaving 24.69 mm for fixation. CONCLUSIONS The transfer of the LT extended with the IF on the footprint of the infraspinatus is feasible. It could be a viable alternative to the currently used grafts in LT transfer in irreparable posterosuperior RCT.

Abstract
Irreparable posterosuperior rotator cuff tears are a challenging treatment problem. Several tendon transfers have been described for the treatment of irreparable tears. Recently the lower trapezius (LT) tendon transfer has grown in popularity. This procedure has shown promise in biomechanical studies, improving the external rotation moment arm at the side. This transfer may be done in several ways, including an open approach with an acromial osteotomy, mini-open, and arthroscopic-assisted. The purpose of this paper is to review the current evidence and rationale for the use of the LT transfer and to describe the available techniques.

Abstract
Although the prevalence of rotator cuff tears is dependent on the size, 11% to 94% of patients experience retear or healing failure after rotator cuff repair. Treatment of patients with failed rotator cuff repair ranges widely, from conservative treatment to arthroplasty. This review article attempts to summarize the most recent and relevant surgical options for failed rotator cuff repair patients, and the outcomes of each treatment, except arthroplasty.

Abstract
INTRODUCTION Superior capsule reconstruction (SCR) has been used for the tendon grafting of massive rotator cuff tears when primary repair is difficult. We examined the postoperative outcomes of SCR for massive rotator cuff tears and the risk factors for postoperative retear. MATERIALS AND METHODS Through this retrospective comparative study, we evaluated 35 patients with an average age of 75.3 (57-90) years who underwent SCR using the technique developed by Mihata et al. Clinical outcomes were evaluated 1 year postoperatively using the Japan Orthopedic Association (JOA) score, University of California Los Angeles (UCLA) shoulder score, elevation angle and the Sugaya classification, which uses a 5-point scale evaluation on magnetic resonance imaging in which types 4 and 5 are considered retears. We also investigated the progression of fatty degeneration before and after surgery and the rupture site of the graft. Acromio-humeral distance (AHD), before and after surgery was measured through X-rays. Rotator cuff tear-related shoulder arthritis was evaluated on plain X-rays using the Hamada stage. Risks of retear were identified using multiple regression analyses for sex, age, Hamada stage and JOA score. RESULTS The JOA score improved from 62.3 ± 9.49 (SD) preoperatively to 84.6 ± 5.66 (SD) postoperatively (P < 0.001). The UCLA score improved from 15.3 ± 3.77 (SD) preoperatively to 30.1 ± 3.11 (SD) postoperatively (P < 0.001). AHD increased from 4.03 mm preoperatively to 6.23 mm postoperatively (P < 0.001). Postoperative retear was observed in seven of the 35 patients. Moreover, retear was observed in five of nine patients with a Hamada stage ≥ 4. Multiple regression analysis revealed that age ≥ 80 years, male sex and Hamada stage ≥ 4 were risk factors for retear. CONCLUSIONS While the postoperative outcomes of SCR are favorable, age, sex and degree of arthropathic change should be considered for surgical indications of SCR.

Abstract
BACKGROUND Irreparable posterosuperior rotator cuff tears cause pain and impaired shoulder function. Latissimus dorsi (LD) transfer has been proven to improve shoulder function, but lower trapezius (LT) transfer has recently been proposed as an alternative. This study aimed to compare the biomechanics of LD and LT transfers and how they are affected by different insertion sites. METHODS The Newcastle shoulder model was used to investigate the biomechanics of these 2 tendon transfers. Computed tomography data sets from 10 healthy subjects were used to customize the model, and virtual LD and LT transfers were performed on supraspinatus, infraspinatus, and teres minor insertion sites. Muscle moment arms and lengths were computed for abduction, forward flexion, and external rotation. RESULTS The LT yields greater abduction moment arms compared with the LD when it is transferred to the native supraspinatus and infraspinatus insertion sites. However, they become adductors when transferred to the native teres minor insertion. Both muscles show strong external rotation moment arms, except for the LT with a supraspinatus insertion. Resting muscle strains were 0.21 (±0.03), 0.12 (±0.02), and 0.06 (±0.03) for the LD and 0.70 (±0.15), 0.61 (±0.13), and 0.58 (±0.13) for the LT for the supraspinatus, infraspinatus, and teres minor insertions, respectively. CONCLUSIONS LT provided better abduction and external rotation moment arms when transferred to the infraspinatus insertion. LD performed better when transferred to the supraspinatus insertion. Overall, LT transfer showed a biomechanical advantage compared with LD transfer because of stronger abduction moment arms. However, significantly larger muscle strains after LT transfer necessitate a tendon allograft to prevent muscle overtensioning.

Abstract
INTRODUCTION This systematic review provides a comprehensive description of different surgical techniques for massive rotator cuff tears (MRCTs) using arthroscopic-assisted latissimus dorsi transfer (A-LDT), reporting clinical outcomes and complications. SOURCES OF DATA We searched the literature on Medline (PubMed), Web of Science and Scopus databases using the combined keywords 'latissimus dorsi', 'tendon', 'transfer', 'rotator cuff tears', 'shoulder' and 'arthroscopy' to identify articles published in English, Spanish, French and Italian. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed for the manuscript selection. AREAS OF AGREEMENT Ten studies (five retrospective and five prospective investigations), all published between 2014 and 2018, fulfilled our inclusion criteria, dealing with 348 (55.7% male) patients, with a mean age of 61.6 years (range 31-83). AREAS OF CONTROVERSY A-LDT is a technical demanding procedure. When compared with the open technique, it does not seem to provide significant subjective and objective clinical outcome improvements. GROWING POINTS A-LDT seems to yield lesser surgical complications and post-operative stiffness. Sparing the deltoid muscle belly could result in a more effective shoulder post-surgery function. AREAS TIMELY FOR DEVELOPING RESEARCH Further comparative randomized controlled trials with longer follow-up are needed to clarify the potentially promising superiority of A-LDT.

Lower trapezius transfer with semitendinosus tendon augmentation: Indication, technique, results. ACTA ACUST UNITED AC 2018; 13:261-268. [PMID: 30546490 PMCID: PMC6267376 DOI: 10.1007/s11678-018-0495-8] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Accepted: 10/09/2018] [Indexed: 11/29/2022]
Abstract
Background Lower trapezius transfer can restore external rotation in brachial plexus palsies. In some cuff tear arthropathies, there is lack of active external rotation with a preservation of forward elevation. We evaluated the clinical outcomes of a lower trapezius transfer extended with a semitendinosus tendon and fixed to the insertion of the infraspinatus via arthroscopy. Methods Between 2013 and 2016, we operated on 14 patients (8 men, 6 women; mean age of 62 years, range: 50–70) to reconstruct irreparable posterosuperior rotator cuff tear. A vertical incision of 6 cm following the medial border of the spine was made to harvest the lower trapezius in extension with the semitendinosus tendon. The extension band of the lower trapezius was fixed laterally via arthroscopy on the great tuberosity at the level of the insertion of the infraspinatus. The proximal stump of this extension band was then fixed medially into the muscle of the lower trapezius with the arm in maximum external rotation. Outcomes were evaluated with the Constant–Murley score, simple shoulder test (SST), and subjective shoulder value (SSV). Results Over a mean follow-up of 24 months (range: 12–36 months), the gain in external rotation with the arm at the side was 24° and 40° in 90° of abduction. The Constant–Murley score improved from 35 to 60 points, the SST from 3.5 to 7.5, the SSV from 30 to 60%, and the pain decreased from 7 to 2 (visual analogue scale, 0–10). Both the lag sign and hornblower sign were negative after this transfer. There were two cases of hematomas, and one was revised because of infection. Conclusion Lower trapezius transfer is a therapeutic option for irreparable posterosuperior cuff tears with a lack of active external rotation and a good subscapularis. Patients can expect improvements in pain and in active external rotation without any loss of active anterior elevation.

Abstract
Recently, patients with shoulder pain have increased rapidly. Of all shoulder disorders, rotator cuff tears (RCTs) are most prevalent in the middle-aged and older adults, which is the primary reason for shoulder surgery in the population. Some authors have reported that up to 30% of total RCTs can be classified as irreparable due to the massive tear size and severe muscle atrophy. In this review article, we provide an overview of treatment methods for irreparable massive RCTs and discuss proper surgical strategies for RCTs that require operative management.

Abstract
This article provides an anatomical and biomechanical framework for the postoperative management and progression of treatment for shoulder arthroplasty. The clinical relevance of normal shoulder anatomy, biomechanics, and pathomechanics related to this surgery is emphasized to provide the reader with an understanding of the rationale for treatment. We review the rehabilitation implications of surgical indications and technique for both traditional total shoulder arthroplasty and reverse total shoulder arthroplasty procedures with an emphasis on biomechanical considerations. Relevant factors that affect rehabilitation outcomes are discussed along with supporting evidence from the literature. Principles to guide and progress treatment are highlighted with a discussion on return to sports with the ultimate objective of providing a comprehensive approach for successful rehabilitation.

Abstract
UNLABELLED Latissimus dorsi tendon transfer is a surgical option for treating irreparable posterosuperior rotator cuff tears, notably when attempting to reconstruct active external rotation. We hypothesized that the positioning of the transfer's point of fixation would differ depending on the desired elbow-to-body external rotation or external rotation with the elbow abducted. MATERIAL AND METHODS Seven shoulders from four whole frozen cadavers were used. We created two systems to install the subject in a semi-seated position to allow external rotation elbow to body and the arm abducted 90°. Traction sutures were positioned on the latissimus dorsi muscle and a massive tear of the rotator cuff was created. We tested six different transfer positions. Muscle contraction of the latissimus dorsi was stimulated using 10-N and 20-N suspended weights. RESULTS The point of fixation of the latissimus dorsi on the humeral head had an influence on the elbow-to-body external rotation and with 90° abduction (P<0.001). The fixation point for a maximum external rotation with the elbow to the body was the anterolateral position (P<0.016). The fixation point for a maximum external rotation at 90° abduction was the position centered on the infraspinatus footprint (P<0.078). CONCLUSION The optimal point of fixation differs depending on whether external rotation is restored at 0° or 90° abduction. LEVEL OF EVIDENCE Fundamental study, anatomic study.

Abstract
BACKGROUND The purpose of this study was to characterize the biomechanical effects of the lower trapezius transfer and to compare it with the latissimus dorsi transfer in a cadaveric model of a massive posterosuperior rotator cuff tear. METHODS Eight cadaveric shoulders were tested at 0°, 30°, and 60° of shoulder abduction. Range of motion, humeral rotational position due to muscle loading, joint reaction forces, and kinematics were measured. All specimens were tested in 4 conditions: intact, massive posterosuperior cuff tear, lower trapezius transfer, and latissimus dorsi transfer. A repeated-measures analysis of variance was used for statistical analysis. RESULTS Internal rotation due to muscle loading increased with massive cuff tear compared with the intact condition (P < .05). The latissimus transfer corrected this change at 0° abduction, whereas the trapezius transfer corrected this at all abduction angles. The massive cuff tear decreased glenohumeral joint compression forces at all abduction angles; these forces were restored by the lower trapezius transfer (P < .05). At maximum humeral internal rotation and 0° of abduction, the humeral head apex shifted superiorly and laterally with massive cuff tear (P < .05); this shift was more closely restored to intact values by the trapezius transfer compared with the latissimus transfer (P < .05). CONCLUSION The lower trapezius transfer is superior to the latissimus transfer at restoring native glenohumeral kinematics and joint reaction forces in our cadaveric model. It may be a promising treatment option for patients with a massive irreparable rotator cuff tear.

Abstract
BACKGROUND AND PURPOSE Irreparable rotator cuff tears are a common cause of pain in adult population, requiring in many cases a surgical treatment. Possible alternatives are debridement, partial repair, muscle transfers and joint replacement. We evaluated two groups of patients with irreparable rotator cuff tear treated surgically: one group received an arthroscopic-assisted latissimus dorsi tendon transfer (LDTT), and the other an arthroscopic rotator cuff partial repair. Aim of our study was to compare clinical results and quality of life in two groups of patients with massive irreparable rotator cuff tear: one receiving an arthroscopic LDTT and the other receiving an arthroscopic rotator cuff partial repair. METHODS Forty patients were assigned to two groups: 20 patients to group TT treated with LDTT and 20 patients to group PR treated with a partial repair. The average follow-up duration was 2.8 years (1-5, SD 3). Pre- and postoperative modified UCLA shoulder score, ROM, measurement of the strength and the rotator cuff quality of life (RC-QOL) were used to asses the outcome. RESULTS LDTT showed significative improvements when compared to partial repair in UCLA score results, strength and RC-QOL questionnaire. No differences were found between the groups in pain relief. CONCLUSION Both techniques are effective in reducing patients' symptoms. We believe that in younger, high-demanding patients with no or mild osteoarthritis, the LDTT represents a valid treatment option with better modified UCLA score improvement and strength at our follow-up.

Abstract
BACKGROUND The variability in functional outcomes and the occurrence of scapular notching and instability after reverse total shoulder arthroplasty remain problems. The objectives of this study were to measure the effect of reverse humeral component neck-shaft angle on impingement-free range of motion, abduction moment, and anterior dislocation force and to evaluate the effect of subscapularis loading on dislocation force. METHODS Six cadaveric shoulders were tested with 155°, 145°, and 135° reverse shoulder humeral neck-shaft angles. The adduction angle at which bone contact occurred and the internal and external rotational impingement-free range of motion angles were measured. Glenohumeral abduction moment was measured at 0° and 30° of abduction, and anterior dislocation forces were measured at 30° of internal rotation, 0°, and 30° of external rotation with and without subscapularis loading. RESULTS Adduction deficit angles for 155°, 145°, and 135° neck-shaft angle were 2° ± 5° of abduction, 7° ± 4° of adduction, and 12° ± 2° of adduction (P < .05). Impingement-free angles of humeral rotation and abduction moments were not statistically different between the neck-shaft angles. The anterior dislocation force was significantly higher for the 135° neck-shaft angle at 30° of external rotation and significantly higher for the 155° neck-shaft angle at 30° of internal rotation (P < .01). The anterior dislocation forces were significantly higher when the subscapularis was loaded (P < .01). CONCLUSIONS The 155° neck-shaft angle was more prone to scapular bone contact during adduction but was more stable at the internally rotated position, which was the least stable humeral rotation position. Subscapularis loading gave further anterior stability with all neck-shaft angles at all positions.

Abstract
Glenohumeral instability has a bimodal age distribution, with most affected patients younger than 40 years, but with a second peak in older patients. Glenohumeral dislocations in older patients often present with complex injury patterns, including rotator cuff tears, fractures, and neurovascular injuries. Glenohumeral instability in patients older than 40 years requires a different approach to treatment. An algorithmic approach aids the surgeon in the stepwise decision-making process necessary to treat this injury pattern.

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

Abstract
PURPOSE Humeral resurfacing arthroplasty represents an alternative option to hemiarthroplasty for treatment of cuff tear arthropathy (CTA), with the advantages as follows: suitability for relatively young and high-demand patients because of preservation of bone stock and no loss of length, less invasive surgery, shorter operation time, no risk of periprosthetic stem fractures, and revision surgery can be undertaken easily. In the current study, resurfacing arthroplasty in combination with latissimus dorsi tendon transfer for CTA was performed. Three hypotheses: first, humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer would improve the overall functional outcome in patients with CTA. Second, this combination would improve humeral external rotation. Third, this combination would improve abduction and shoulder elevation. METHODS Study was conducted as an observational case series. Fourteen patients (nine ♀ and five ♂) having CTA were included. Follow-up was carried out at the end of the 28th month for all patients. Constant Score was used for follow-up evaluation. Dorso-axillary approach was used for latissimus dorsi tendon transfer and ventral deltopectoral approach for Copeland resurfacing. Tendons were fixed to the greater tuberosity with two anchors. RESULTS The absolute Constant Score significantly improved from 34 preoperatively to 69 postoperatively, relative Constant Score from 42 to 91%, elevation from 95° to 138°, abduction from 88° to 147°, and external rotation from 16° to 22° (not significant). CONCLUSION Humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer in patients having CTA with preserved subscapularis function has satisfactory short-term functional clinical outcome.
