Project description:BackgroundArthroscopic rotator cuff repair (ARCR) is among the most commonly performed orthopaedic procedures. Several factors-including age, sex, and tear severity-have been identified as predictors for outcome after repair. The influence of the tear etiology on functional and structural outcome remains controversial.PurposeTo investigate the influence of tear etiology (degenerative vs traumatic) on functional and structural outcomes in patients with supraspinatus tendon tears.Study designCohort study; Level of evidence, 2.MethodsPatients undergoing ARCR from 19 centers were prospectively enrolled between June 2020 and November 2021. Full-thickness, nonmassive tears involving the supraspinatus tendon were included. Tears were classified as degenerative (chronic shoulder pain, no history of trauma) or traumatic (acute, traumatic onset, no previous shoulder pain). Range of motion, strength, the Subjective Shoulder Value, the Oxford Shoulder Score (OSS), and the Constant-Murley Score (CMS) were assessed before (baseline) and 6 and 12 months after ARCR. The Subjective Shoulder Value and the OSS were also determined at the 24-month follow-up. Repair integrity after 12 months was documented, as well as additional surgeries up to the 24-month follow-up. Tear groups were compared using mixed models adjusted for potential confounding effects.ResultsFrom a cohort of 973 consecutive patients, 421 patients (degenerative tear, n = 230; traumatic tear, n = 191) met the inclusion criteria. The traumatic tear group had lower mean baseline OSS and CMS scores but significantly greater score changes 12 months after ARCR (OSS, 18 [SD, 8]; CMS, 34 [SD,18] vs degenerative: OSS, 15 [SD, 8]; CMS, 22 [SD, 15]) (P < .001) and significantly higher 12-month overall scores (OSS, 44 [SD, 5]; CMS, 79 [SD, 9] vs degenerative: OSS, 42 [SD, 7]; CMS, 76 [SD, 12]) (P≤ .006). At the 24-month follow-up, neither the OSS (degenerative, 44 [SD, 6]; traumatic, 45 [SD, 6]; P = .346) nor the rates of repair failure (degenerative, 14 [6.1%]; traumatic 12 [6.3%]; P = .934) and additional surgeries (7 [3%]; 7 [3.7%]; P = .723) differed between groups.ConclusionPatients with degenerative and traumatic full-thickness supraspinatus tendon tears who had ARCR show satisfactory short-term functional results. Although patients with traumatic tears have lower baseline functional scores, they rehabilitate over time and show comparable clinical results 1 year after ARCR. Similarly, degenerative and traumatic rotator cuff tears show comparable structural outcomes, which suggests that degenerated tendons retain healing potential.

Project description:BackgroundsPathology of the long head biceps tendon (LHBT) is associated with rotator cuff tears but whether the LHBT texture changes following supraspinatus tendon full thickness tear (SSFT) can be detected at the extra-articular segment remains unknown. This cross-sectional study aimed to explore the morphological differences of the LHBT in shoulders with and without deficient rotator cuffs by using quantitative ultrasound.Materials and methodsWe selected 145 cases with SSFT and 145 age-and- gender-matched controls. The width, thickness, flattening ratio, cross-sectional area, and echogenicity ratio of the LHBT were measured and a general linear model was used to clarify the relationship between rotator cuff pathology and LHBT morphology. The receiver operating characteristic curves of each parameter were constructed for SSFT discrimination and the maximal Youden indexes were used to define the best cut-off points.ResultsWe found increased thickness and cross-sectional area but decreased flattening ratio in shoulders with SSFT, and no between-group differences in the width and echogenicity ratio. The LHBT appearance was modified by biceps peritendinous effusion and medial subluxation, but not by the size of SSFT. The flattening ratio was the best discriminator for SSFT with an area under curve of 0.81 (95% confidence interval, 0.76-0.86). The cut-off values to differentiate between the non-tear and tear groups were 2.00 mm of the thickness, 1.73 of the flattening ratio and 10.53 mm(2) of the cross-sectional area.ConclusionQuantitative ultrasound facilitated the detection of the LHBT morphological changes following SSFT and demonstrated its potential utility in discriminating rotator cuff deficiency.

Project description:Rotator cuff tears are common conditions that can alter shoulder mechanics and may lead to damage of intact joint tissues. These injuries are of particular concern in populations who perform tasks requiring repetitive overhead activity (e.g., athletes and laborers) and who are likely to return to aggressive pre-injury activity levels despite limited understanding of the potentially damaging effects on the remaining tissues. Therefore, we investigated the effect of returning to overuse activity following a supraspinatus tear on shoulder function and the mechanical properties of the remaining intact tendons and glenoid cartilage. Forty rats underwent 4 weeks of overuse activity to create a tendinopathic condition followed by detachment of the supraspinatus tendon and were then randomized into two groups: continued overuse or cage activity. Ambulatory measurements were performed throughout the 8 weeks prior to euthaniasia, and properties of the adjacent tendons and cartilage were evaluated. Results demonstrated that shoulder function was not compromised in the return to overuse group. However, alterations of the glenoid cartilage and biceps tendon properties occurred. Our results help define the contributory roles of common mechanical injury mechanisms and provide a framework by which physicians could better prescribe long-term treatment strategies for patients.

Project description:BackgrounFull-thickness rotator cuff tear is common in the older population. The incidence of traumatic deltoid tears post-surgery is well addressed. However, non-traumatic spontaneous injury is not well recognized despite a few case reports and previous studies. The aim of the study is to determine the incidence and association of deltoid tear among patients with non-traumatic full-thickness rotator cuff tear using shoulder magnetic resonance imaging.MethodsA retrospective cross-sectional study was conducted of 271 shoulders magnetic resonance imaging examinations with full-thickness rotator cuff tear between 2012 and 2022. The analyzed variables were full-thickness rotator cuff tear size, tear grading (small, medium, large, and massive), muscle fatty degeneration, and deltoid tear. Acromio-humeral interval was also recorded and analyzed on the anteroposterior projection of shoulder radiographs.ResultsThe incidence of deltoid tear was 7% (19 cases), encountered in eleven females (6.4%) and eight males (8%) with a mean age of 65 years. Deltoid tears were located on the right side in fifteen patients (9.4%) and on the left side in four patients (3.6%). The Man-Whitney U test indicated a significant association between deltoid tears and full-thickness rotator cuff tear, P < 0.001. The deltoid tear was more notably associated with large and massive full-thickness rotator cuff tear (16.7% and 42.3%, respectively), P < 0.001. Acromio-humeral interval showed a significant difference between the deltoid and non-deltoid cases, P = 0.045.ConclusionThe incidence and association of deltoid tears with full-thickness rotator cuff tear with no prior surgical intervention or traumatic insults were considered significant, with a positive impact of large and massive tear size and association of muscle fatty degeneration. This association is statistically significant and should be adequately evaluated by the radiologist.

Project description:A humeral avulsion of the glenohumeral ligament, or HAGL, lesion is a rare yet debilitating shoulder injury, which can lead to recurrent instability, pain, and overall shoulder dysfunction. The diagnosis is often difficult, requiring both high clinical suspicion, as well as identification on magnetic resonance imaging. In patients with an anterior HAGL, repair often requires an open approach. In extremely rare circumstances, the initial traumatic event that causes a HAGL can also cause disruption of the supraspinatus and subscapularis insertions on the humeral head. We have termed this the "naked humeral head". The purpose of this technical note is to describe our preferred technique to surgically treat the naked humeral head by repairing a supraspinatus avulsion fracture, HAGL lesion, and complete subscapularis tear.

Project description:IntroductionAfter a vaccine administration, many people have localized symptoms such as pain, redness, warmth, swelling, itching and/or bruising, which usually improve in a few days. If the clinical symptoms do not improve in this period, a shoulder injury related to vaccine administration (SIRVA) should be ruled out. The most common cause of a SIRVA is an improper injection technique. Herein, we reported the first case of combined subacromial-subdeltoid bursitis and supraspinatus tendon tear which was apparently caused by an improper COVID-19 vaccination technique.Case presentationA 51-year-old Thai female began to experience severe right shoulder pain about 3 hours after receiving a COVID-19 vaccination. Ultrasonography showed combined subacromial-subdeltoid bursitis and supraspinatus tendon tear. Her clinical symptoms gradually improved after treatment with an oral non-steroidal anti-inflammatory drug. Our investigation found that an improper injection technique had been used, namely inserting the needle too deeply, and using an incorrect landmark.ConclusionWe report a case of combined subacromial-subdeltoid bursitis and supraspinatus tendon tear following a second dose of the Oxford-AstraZeneca COVID-19 vaccine. This is a rare condition which is usually related to an incorrect injection technique. To reduce the chance of SIRVA, the healthcare worker giving the injection should pay careful attention to find the appropriate landmark, and ensuring the correct needle length and direction of the injection.

Project description:PurposeTo evaluate the outcome of superior capsular reconstruction for isolated subscapularis tears using a decellularized porcine allograft as a superior capsular reconstruction.MethodsPatients who had symptomatic tears of supraspinatus who had failed to improve a conservative rehabilitation program were included. Previous surgery to the shoulder was not a bar to inclusion. Patients were assessed preoperatively and postoperatively with the Oxford Shoulder Score (OSS), the single assessment numeric evaluation (SANE) score, as well as clinically assessed for their shoulder range of motion (ROM). Patients were followed up with in-person clinic appointments for the first year, followed by a postal questionnaire and telephone consultation at a minimum of 2 years following surgery.ResultsTwenty patients (11 males and 9 females) with a mean age of 67.5 years were included (range: 54-72 years). The average follow-up period was 31 months (24-50). The mean improvement in OSS was 14 points (P < .001), SANE score was 27 points (P < .01). Significant improvements in mean ROM were recorded (flexion 80.7°; P < .001; abduction: 81°; P < .001; external rotation: 31°; P < .001). Six patients suffered SCR failures diagnosed by magnetic resonance imaging, despite this they still recorded improvements in recorded OSS, SANE and ROM (excluding external rotation). Patient demographics for failed superior capsule reconstruction (SCR) highlighted smoking and revision surgery as risk factors.ConclusionsSCR appears to be a viable option for patients with symptomatic, isolated, and irreparable tears of the supraspinatus. Our results demonstrate that there are significant improvements in outcome scores and active range of motion, even in the subgroup in whom postoperative structural failure of the SCR was identified. We recommend caution in patients who have previously failed rotator cuff repair and in heavy smokers.Level of evidenceLevel IV, therapeutic case series.

Project description:The middle glenohumeral ligament (MGHL) typically contributes partially to the anterior stability of the shoulder. In a very limited number of cases, the MGHL can cause abrasion on the upper edge of the subscapularis causing persistent pain symptoms for patients. The condition is exacerbated by internal rotation of the arm. In this Technical Note, we describe this entity and call it the SAM lesion (Subscapularis Abrasion from the MGHL). We present a technique of addressing this lesion.

Project description:Mechanical subacromial rotator cuff compression is one theoretical mechanism in the pathogenesis of rotator cuff disease. However, the relationship between shoulder kinematics and mechanical subacromial rotator cuff compression across the range of humeral elevation motion is not well understood. The purpose of this study was to investigate the effect of humeral elevation on subacromial compression risk of the supraspinatus during a simulated functional reaching task. Three-dimensional anatomical models were reconstructed from shoulder magnetic resonance images acquired from 20 subjects (10 asymptomatic, 10 symptomatic). Standardized glenohumeral kinematics from a simulated reaching task were imposed on the anatomic models and analyzed at 0, 30, 60, and 90° humerothoracic elevation. Five magnitudes of humeral retroversion were also imposed on the models at each angle of humerothoracic elevation to investigate the impact of retroversion on subacromial proximities. The minimum distance between the coracoacromial arch and supraspinatus tendon and footprint were quantified. When contact occurred, the magnitude of the intersecting volume between the supraspinatus tendon and coracoacromial arch was also quantified. The smallest minimum distance from the coracoacromial arch to the supraspinatus footprint occurred between 30 and 90°, while the smallest minimum distance to the supraspinatus tendon occurred between 0 and 60°. The magnitude of humeral retroversion did not significantly affect minimum distance to the supraspinatus tendon except at 60 or 90° humerothoracic elevation. The results of this study provide support for mechanical rotator cuff compression as a potential mechanism for the development of rotator cuff disease. © 2017 Orthopaedic Research Society.
