Abstract
Background To examine whether traumatic rotator cuff repairs (RCRs) differ in postoperative rotator cuff tendon integrity and functional outcomes from degenerative RCRs. Methods RCRs performed by a single surgeon were retrospectively identified. The inclusion criteria were repairable Goutallier grades 0 to 2 full-thickness rotator cuff tears. Demographic and clinical data as well as radiological results were compared. A multivariate logistic regression of the of patient acceptable symptom state for American Shoulder and Elbow Surgeons (ASES) score was performed to evaluate whether the origin of tear led to a different relative risk (RR) independently from tear and surgical characteristics. Results A total of 616 consecutive shoulders (304 traumatic and 312 degenerative) were finally included. Traumatic ruptures presented a greater distribution of male (72% vs 51%, P < .001) and younger patients (53 vs 57 years, P < .001), as well as earlier onset of symptoms (3 vs 15 months, P < .001), reduced range of motion in preoperative assessment for forward elevation (130° vs 150°, P < .001), and slightly greater preoperative ASES (46.5 ± 19.7 vs 50.0 ± 18.0, P = .022) and Constant (47.0 ± 20.2 vs 52.0 ± 18.9, P = .001) scores. Degenerative tears presented a lower proportion of grade 3 tendon coronal retraction (11% vs 18%, P = .031). Postoperative tendon integrity at 6 months was comparable for both groups, predominantly Sugaya types 1 and 2 (91% traumatic; 92% degenerative, P = .371). Both groups exhibited favorable outcomes in range of motion and postoperative functional scores at last follow-up. The multivariate regression confirmed that the tear origin was not significantly associated with patient acceptable symptom state achievement (P = .201) but rather with greater preoperative ASES score (RR, 1.01), men (RR, 1.16) and workers' compensation (RR, 0.65) (P < .05). Conclusions Traumatic cases were frequent, involved younger patients, more frequently affected the anterior rotator cuff, and were associated with more severe tendon retraction. Traumatic and degenerative RCRs lead to comparable clinical and radiologic results. Level of Evidence Level III, retrospective comparative study.

Abstract
Subscapularis (SSc) repairs are not free of failure and continues to pose a challenging problem. Although various biological and structural augmentation methods are available for the posterosuperior rotator cuff, few options have been explored for the anterior one. In the Technical Note, we describe an all-arthroscopic technique in which we use the long head of the biceps tendon (LHBT) as a pediculated autograft to reinforce an SSc repair. After SSc repair and LHBT tenodesis, the intra-articular portion of the LHBT is placed on the upper part of the SSc tendon at the rotator interval. Repurposing the otherwise-discarded tendon brings several biological and mechanical advantages at a lower cost without donor-site morbidity.

Lädermann A. Editorial Commentary: Shoulder Arthroscopic Dynamic Anterior Stabilization Is Effective for Anteroinferior Shoulder Instability With Limited Anterior Bone Loss. Arthroscopy 2023; 39:1628-1629.

Abstract
Shoulder dynamic anterior stabilization (DAS) is an efficient and well-established glenohumeral stabilization technique, offering an arthroscopic alternative to Latarjet and glenoid reconstruction with distal tibial allograft or the iliac crest autograft. DAS is essentially an augmented Bankart procedure and can be performed using transfer of either the long head of the biceps tendon or the conjoined tendon. Both result in similar and acceptable rates of recurrences, complications, return to sport, and subjective shoulder function. However, the effectiveness of Bankart repair on shoulder stability decreases significantly over time, so long-term follow-up evaluations of DAS are required. The best indication for DAS may be anteroinferior shoulder instability with limited anterior bone loss.

A comparison of the MRI findings of the operated and healthy shoulders of the patients. Turk J Med Sci 2023; 53:273-281. [PMID: 36945924 PMCID: PMC10387881 DOI: 10.55730/1300-0144.5582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 10/22/2022] [Indexed: 03/23/2023] Open
Abstract
BACKGROUND : The purpose of this study is to investigate whether the etiological factors accepted as causes of idiopathic subscapularis tears are true or not when the comparison is made with the opposite side healthy shoulder of the patients who underwent arthroscopic repair for an isolated subscapularis tear. METHODS Sixteen patients who underwent shoulder arthroscopy between February 2016 and January 2018 and were diagnosed with isolated subscapularis tear were evaluated. The coracohumeral distance (CHDax), coracoid overlap (CO), and tuberculum minus cysts (TMC) were evaluated on the axial images of the MRI studies while the acromiohumeral distance (AHDsag), CHDsag, and subscapularis tendon slip number (STSN) on the sagittal oblique images and the AHDcor and SLAP lesion on the coronal oblique images. Degeneration of the coracoacromial ligament was evaluated during arthroscopy. RESULTS The mean CHDsag (11.26-10.08), CHDax (10.63-9.98), CO (14.2-15.43), AHDsag (8-7.66), and AHDcor (7.65-7.68) measurements (operated side-healthy side, respectively) were statistically similar (p > 0.05). No statistically significant difference was found between TMC and STSN in healthy and operated shoulders (p > 0.05). There was mild coracoacromial ligament fraying in 4 (25%) and obvious coracoacromial ligament fraying in 8 (50%) which indicated subacromial impingement in 75% of the patients. DISCUSSION The parameters of the coracoid process did not reveal any significant difference between the operated (for an isolated subscapularis tear) and opposite-side healthy shoulders of the patients. However, coracoacromial ligament degeneration was present in 75% of the patients.

Abstract
BACKGROUND Differentiation between subacromial impingement versus subcoracoid impingement are important for the treatment target. We evaluated the correlations between coracohumeral ligament (CHL) thickness and distance (CHD) and characterized the CHL and subscapularis (SSC) in subcoracoid impingement subjects. METHODS An observational, cross-sectional study was carried out. Twenty subcoracoid impingement subjects and age/gender matched controls were assessed in 4 different shoulder positions by ultrasonography. RESULTS Moderate correlations between CHL thickness with CHD (r = 0.455 in neutral rotation, p = 0.044; r = 0.483 in interior rotation, p = 0.031) were found in subacromial subjects. Subcoracoid impingement subjects had greater CHL thickness (difference = 0.3 mm, effect size = 0.85, p = 0.006), SSC tendon thickness (difference = 0.7 mm, effect size = 0.92, p = 0.01) and SSC/CHD occupation ratio (difference = 8%, effect size = 0.95, p = 0.005) compared with the control. CONCLUSIONS Coracohumeral distance is related to ligament thickness, especially in subacromial impingement subjects. Increased coracohumeral ligament and subscapularis thickness as well as decreased subscapularis/coracohumeral distance occupation ratio are characterized in subcoracoid impingement subjects. These quantitative measurements can be useful in identifying patients at risk of subcoracoid impingement from subacromial impingement.

Abstract
This study describes measurements between the coracoid, glenoid, and humerus; characterizes coracoid shape, rotator cuff fatty infiltration, and quantitatively evaluates coracoid impingement and its association with anterosuperior rotator cuff tears (ASCT). 193 shoulder magnetic resonance imaging (MRI) scans demonstrating: rotator cuff tear; isolated tear of the supraspinatus; tear of supraspinatus and subscapularis, were included. MRI measurements included coracohumeral interval (CHI), coracoid overlap (CO), coracoid recess (CR), coracoglenoid angle (CGA), and coracoglenoid interval (CGI) on axial slices; acromiohumeral interval (AHI) on coronal slices; and coracohumeral interval (CHI) and coracoacromial ligament (CAL) thickness on sagittal slices. The coracoid shape was classified as flat, curved, or hooked. An Independent T-test was used to compare the MRI measurements and the different rotator cuff tear groups. In 79% of the patients with ASCT tears, the coracoid was curved. Axial CHI, CGA, sagittal CHI, and AHI were decreased in ASCT when compared to no tears and isolated supraspinatus tears (p < 0.05). CO was increased in ASCT compared to no tears and isolated supraspinatus tears (p < 0.05). Patients with an ASCT had a significantly increased subscapularis and supraspinatus Goutallier fatty infiltration score when compared to no tear and isolated supraspinatus tears (p < 0.05). These quantitative measurements may be useful in identifying patients at risk for ASCT. Level of Evidence III.

Orthop J Sports Med 2022; 10:23259671221077947. [PMID: 35340899 PMCID: PMC8951046 DOI: 10.1177/23259671221077947] [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: 09/28/2021] [Accepted: 10/22/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Arthroscopic coracoplasty is a procedure for patients affected by subcoracoid
impingement. To date, there is no consensus on how much of the coracoid can
be resected with an arthroscopic burr without compromising its
stability. Purpose: To determine the maximum amount of the coracoid that can be resected during
arthroscopic coracoplasty without leading to coracoid fracture or avulsion
of the conjoint tendon during simulated activities of daily living
(ADLs). Study Design: Controlled laboratory study. Methods: A biomechanical cadaveric study was performed with 24 shoulders (15 male, 9
female; mean age, 81 ± 7.9 years). Specimens were randomized into 3
treatment groups: group A (native coracoid), group B (3-mm coracoplasty),
and group C (5-mm coracoplasty). Coracoid anatomic measurements were
documented before and after coracoplasty. The scapula was potted, and a
traction force was applied through the conjoint tendon. The stiffness and
load to failure (LTF) were determined for each specimen. Results: The mean coracoid thicknesses in groups A through C were 7.2, 7.7, and 7.8
mm, respectively, and the mean LTFs were 428 ± 127, 284 ± 77, and 159 ± 87
N, respectively. Compared with specimens in group A, a significantly lower
LTF was seen in specimens in group B (P = .022) and group C
(P < .001). Postoperatively, coracoids with a
thickness ≥4 mm were able to withstand ADLs. Conclusion: While even a 3-mm coracoplasty caused significant weakening of the coracoid,
the individual failure loads were higher than those of the predicted ADLs. A
critical value of 4 mm of coracoid thickness should be preserved to ensure
the stability of the coracoid process. Clinical Relevance: In correspondence with the findings of this study, careful preoperative
planning should be used to measure the maximum reasonable amount of
coracoplasty to be performed. A postoperative coracoid thickness of 4 mm
should remain.

Abstract
The initial reverse shoulder arthroplasty (RSA), designed by Paul Grammont, was intended to treat rotator cuff tear arthropathy in elderly patients. In the early experience, high complication rates (up to 24%) and revision rates (up to 50%) were reported.The most common complications reported were scapular notching, whereas clinically more relevant complications such as instability and acromial fractures were less commonly described.Zumstein et al defined a 'complication' following RSA as any intraoperative or postoperative event that was likely to have a negative influence on the patient's final outcome.High rates of complications related to the Grammont RSA design led to development of non-Grammont designs, with 135 or 145 degrees of humeral inclination, multiple options for glenosphere size and eccentricity, improved baseplate fixation which facilitated glenoid-sided lateralization, and the option of humeral-sided lateralization.Improved implant characteristics combined with surgeon experience led to a dramatic fall in the majority of complications. However, we still lack a suitable solution for several complications, such as acromial stress fracture. Cite this article: EFORT Open Rev 2021;6:1097-1108. DOI: 10.1302/2058-5241.6.210039.

Abstract
Purpose To present the clinical and imaging findings and results of treatment in patients with intra-articular long head of the biceps tendon (LHBT) adhesion to the undersurface of the rotator cuff found incidentally during shoulder arthroscopy. Methods Patients with intra-articular LHBT adhesion to the undersurface of the rotator cuff found incidentally during arthroscopy were included with a minimal 2-year follow-up. Demographic data, images, and physical examinations were recorded. LHBT release, tenotomy, or tenodesis were performed according to the patient’s age and surgeon’s preference. Results Twelve patients were included in the study. All of them presented with chronic anterior shoulder pain and positive Speed and O’Brien tests. The average age was 46.8 ± 17 years (range 20-79 years) and the pain sustained from 6 to 96 (average 25.5 ± 28.6) months. Before the operation, 6 patients had a positive Jobe’s test, 1 had a positive lift-off test, and all had positive O’Brien and Speed tests and tenderness over the LHBT. Three release, 4 tenotomy, and 5 LHBT tenodesis were done in addition to other procedures if needed. All range of motion except external rotation, pain visual analog score, and functional outcome scores showed significant improvement at 6 months after surgery. There were no significant differences in range of motion and functional scores between 6 months and 12 months postoperatively. No difference was found in LHBT scores at 6 and 12 months after the operation. Magnetic resonance imaging revealed thickened coracohumeral ligament overlying the LHBT. Conclusions Patients who had intra-articular LHBT adhesion to the undersurface of the rotator cuff and underwent release of the adhesion around LHBT, tenotomy, or tenodesis all had good clinical outcomes. The lesion was observed in 2.2% of all shoulder arthroscopies. Although difficult to diagnose before surgery, surgeons should be aware of this unusual condition in patients with chronic and insidious anterior shoulder pain.

Abstract
INTRODUCTION There is no consensus on how to perform acromioplasty, particularly regarding the level and extent of bone resection, which depend on scapular and humeral morphologies. HYPOTHESIS We aimed to determine whether computer-assisted acromioplasty planning helps surgeons remove impinging bone, reduce unnecessary resections, and improve short-term outcomes of rotator cuff tears (RCR). PATIENTS AND METHODS We randomized 64 patients undergoing RCR of full-thickness supraspinatus tears into two groups: 'guided acromioplasty' (GA) and 'freehand acromioplasty' (FA). The pre- and post-operative scapula models were reconstructed using computed-tomography scans to quantify impinging bone removal, unnecessary bone resections, and identify zones of acromial bone removal. All patients were evaluated preoperatively and at 6 months to assess their range of motion (ROM), functional scores and tendon integrity using ultrasound. RESULTS The two groups did not differ in demographics, clinical or morphologic characteristics. Compared to FA, GA tended to lower impinging bone removal (55±26% vs. 43±27%, p=0.087) and to increase unnecessary resection of the total bone removed (49±22% vs. 57±27%, p=0.248). GA resulted in significant anterior under-resection, while FA resulted in significant medial over-resection. Clinical outcomes and ROM improved significantly for all patients, except for internal rotation in the GA group. There were no other significant differences between the two groups, neither in terms of post-operative scores nor in terms of clinical net improvements, nor tendon repair integrity. CONCLUSIONS This computer-assisted planning for acromioplasty during RCR proved no benefits in terms of bone removal, tendon healing, or clinical outcomes. Nonetheless such planning tools could help less experienced surgeons improve the efficacy of acromioplasty. LEVEL OF PROOF I, Randomized controlled trial (Therapeutic study).

Abstract
Background To date, there is no consensus on when and how to perform acromioplasty during rotator cuff repair (RCR). We aimed to determine the volume of impinging bone removed during acromioplasty and whether it influences postoperative range of motion (ROM) and clinical scores after RCR. Methods Preoperative and postoperative computed tomography scans of 57 shoulders that underwent RCR were used to reconstruct scapula models to simulate volumes of impinging acromial bone preoperatively and then compare them to the volumes of bone resected postoperatively to calculate the proportions of desired (ideal) vs. unnecessary (excess) resections. All patients were evaluated preoperatively and at 6 months to assess ROM and functional scores. Results The volume of impinging bone identified was 3.5 ± 2.3 cm3, of which 1.6 ± 1.2 cm3 (50% ± 27%) was removed during acromioplasty. The volume of impinging bone identified was not correlated with preoperative critical shoulder angle (r = 0.025, P = .853), nor with glenoid inclination (r = -0.024, P = .857). The volume of bone removed was 3.7 ± 2.2 cm3, of which 2.1 ± 1.6 cm3 (53% ± 24%) were unnecessary resections. Multivariable analyses revealed that more extensive removal of impinging bone significantly improved internal rotation with the arm at 90° of abduction (beta, 27.5, P = .048) but did not affect other shoulder movements or clinical scores. Conclusions Acromioplasty removed only 50% of the estimated volume of impinging acromial bone. More extensive removal of impinging bone significantly improved internal rotation with the arm at 90° of abduction.
