Background: The benefits of platelet-rich plasma (PRP) for the treatment of rotator cuff tears remain inconclusive, as it is administered either as an adjuvant to surgical repair or as a primary infiltration without targeting the index lesion, which could dilute its effect. Purpose: To determine whether PRP infiltrations are superior to saline solution infiltrations (placebo) at improving healing, pain, and function when injected under ultrasound guidance within isolated interstitial supraspinatus tears. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: In this single-center, double-blinded, randomized controlled trial, 80 adults with symptomatic isolated interstitial tears of the supraspinatus, confirmed by magnetic resonance arthrography, were randomized to PRP or saline injections. Each patient received 2 injections with a 1-month interval. The primary outcome was the change in lesion volume, calculated on magnetic resonance arthrography, at 7 months. The secondary outcomes were improvements in shoulder pain and the Single Assessment Numerical Evaluation (SANE) score at >12 months. Results: Preoperative patient characteristics did not differ between the 2 groups. At 7 months, there were no significant differences between the PRP and control groups in terms of a decrease in lesion size (–0.3 ± 23.6 mm3 vs –8.1 ± 84.7 mm3, respectively; P = .175); reduction of pain on a visual analog scale (VAS) (–2.3 ± 3.0 vs –2.0 ± 3.0, respectively; P = .586); and improvement in SANE (16.7 ± 20.0 vs 14.9 ± 29.0, respectively; P = .650), Constant (8.6 ± 13.0 vs 10.7 ± 19.0, respectively; P = .596), and American Shoulder and Elbow Surgeons (19.5 ± 20.0 vs 21.9 ± 28.0, respectively; P = .665) scores. At >12 months, there were no significant differences between the PRP and control groups in terms of a reduction of pain on a VAS (–3.3 ± 2.6 vs –2.3 ± 3.2, respectively; P = .087) or improvement in the SANE score (24.4 ± 27.5 vs 23.4 ± 24.9, respectively; P = .846). At 19.5 ± 5.3 months, the incidence of adverse effects (pain >48 hours, frozen shoulder, extension of lesion) was significantly higher in the PRP group than the control group (54% vs 26%, respectively; P = .020). Conclusion: PRP injections within interstitial supraspinatus tears did not improve tendon healing or clinical scores compared with saline injections and were associated with more adverse events.

Objectives: Patients are commonly advised to wear a sling for 4-6 weeks after rotator cuff repair (RCR) despite negative effects of early immobilization and benefits of motion rehabilitation. The study aimed to compare clinical and radiographic outcomes up to 6 months following RCR with sling immobilization and without sling immobilization. Methods: We randomized 80 patients scheduled for arthroscopic repair of small or medium superior rotator cuff tears into 2 equal groups: 'sling' and 'no-sling' groups. Passive mobilization was performed in both groups during the first 4 postoperative weeks followed by a progressive active mobilization. Patients were evaluated clinically at 10 days, 1.5, 3 and 6 months, and using ultrasound at 6 months. Uni-and multi-variable analyses were performed to determine if postoperative scores are associated with gender, age at surgery, immobilization, arm dominance, biceps procedure, resection of the distal clavicle, as well as preoperative scores. Results: The two groups had similar preoperative patient characteristics, function, or adjuvant procedures. At 10 days, there was no difference in pain among the two groups (5.2±2.3 vs 5.2±1.9, p=0.996). In comparison to the sling group, the no-sling group showed greater external rotation (23.5±15.6 vs 15.3±14.6, p=0.017) and active elevation (110.9±31.9 vs 97.0±25.0, p=0.038) at 1.5 months, as well as better active elevation (139.0±24.7 vs 125.8±24.4, p=0.015) and internal rotation (>T12 in 50% vs 27.5%, p=0.011) at 3 months. Ultrasound revealed no differences at 6 months in tendon thickness anteriorly (p=0.472) or posteriorly (p=639), bursitis (p=1.000), echogenicity (p=0.422), or repair integrity (p=0.902). Multi-variable analyses confirmed that ASES score increased with patient age (beta, 0.60; p=0.009), SANE decreased with sling immobilization (beta,-6.3; p=0.014), and that pain increased with sling immobilization (beta, 0.77; p=0.022). Conclusion: No immobilization after RCR is associated with better early mobility and functional scores in comparison to sling immobilization. Postoperative immobilization with slings may therefore not be required for patients treated for small or medium tears.
Background: Patients are commonly advised to wear a sling for 4 to 6 weeks after rotator cuff repair despite negative effects of early immobilization and benefits of motion rehabilitation. The aim of this study was to compare clinical and radiographic outcomes up to 6 months following rotator cuff repair with and without postoperative sling immobilization. Methods: We randomized 80 patients scheduled for arthroscopic repair of a small or medium superior rotator cuff tear into sling and no-sling groups (40 patients each). Passive mobilization was performed in both groups during the first 4 postoperative weeks, and this was followed by progressive active mobilization. Patients were evaluated clinically at 10 days and 1.5, 3, and 6 months and using ultrasound at 6 months. Univariable and multivariable analyses were performed to determine if postoperative scores were associated with sex, age at surgery, immobilization, arm dominance, a biceps procedure, resection of the distal part of the clavicle, or preoperative scores. Results: The sling and no-sling groups had similar preoperative patient characteristics, function, and adjuvant procedures. At 10 days, there was no difference in pain between the 2 groups (mean pain score [and standard deviation], 5.2 ± 2.3 versus 5.2 ± 1.9, p = 0.996). In comparison with the sling group, the no-sling group showed greater mean external rotation (23.5° ± 15.6° versus 15.3° ± 14.6°, p = 0.017) and active elevation (110.9° ± 31.9° versus 97.0° ± 25.0°, p = 0.038) at 1.5 months as well as better mean active elevation (139.0° ± 24.7° versus 125.8° ± 24.4°, p = 0.015) and internal rotation (T12 or above in 50% versus 28%, p = 0.011) at 3 months. Ultrasound evaluation revealed no significant differences at 6 months in tendon thickness anteriorly (p = 0.472) or posteriorly (p = 0.639), bursitis (p = 1.000), echogenicity (p = 0.422), or repair integrity (p = 0.902). Multivariable analyses confirmed that the mean American Shoulder and Elbow Surgeons (ASES) score increased with patient age (beta, 0.60; p = 0.009), the Single Assessment Numeric Evaluation (SANE) decreased with sling immobilization (beta, −6.33; p = 0.014), and pain increased with sling immobilization (beta, 0.77; p = 0.022). Conclusions: No immobilization after rotator cuff repair is associated with better early mobility and functional scores in comparison with sling immobilization. Postoperative immobilization with a sling may therefore not be required for patients treated for a small or medium tendon tear. Level of Evidence: Therapeutic Level I.

Despite the fact that surgery is commonly used to treat glenohumeral instability, there is no evidence that such treatment effectively corrects glenohumeral translation. The purpose of this prospective clinical study was to analyze the effect of surgical stabilization on glenohumeral translation.Glenohumeral translation was assessed in 11 patients preoperatively and 1 year postoperatively following surgical stabilization for anterior shoulder instability. Translation was measured using optical motion capture and computed tomography.Preoperatively, anterior translation of the affected shoulder was bigger in comparison to the normal contralateral side. Differences were significant for flexion and abduction movements (P < 0.001). Postoperatively, no patients demonstrated apprehension and all functional scores were improved. Despite absence of apprehension, postoperative anterior translation for the surgically stabilized shoulders was not significantly different from the preoperative values.While surgical treatment for anterior instability limits the chance of dislocation, it does not seem to restore glenohumeral translation during functional range of motion. Such persistent microinstability may explain residual pain, apprehension, inability to return to activity and even emergence of dislocation arthropathy that is seen in some patients. Further research is necessary to better understand the causes, effects, and treatment of residual microinstability following surgical stabilization of the shoulder.
BackgroundWith the growth of reverse shoulder arthroplasty (RSA), it is becoming increasingly necessary to establish the most cost-effective methods for the procedure. The surgical approach is one factor that may influence the cost and outcome of RSA. The purpose of this study was to compare the clinical results of a subscapularis- and deltoid-sparing (SSCS) approach to a traditional deltopectoral (TDP) approach for RSA. The hypothesis was that the SSCS approach would be associated with decreased length of stay (LOS), equal complication rate, and better short-term outcomes compared to the TDP approach.MethodsA prospective evaluation was performed on patients undergoing RSA over a 2-year period. A deltopectoral incision was used followed by either an SSCS approach or a traditional tenotomy of the subscapularis (TDP). LOS, adverse events, physical therapy utilization, and patient satisfaction were collected in the 12 months following RSA.ResultsLOS was shorter with the SSCS approach compared to the TDP approach (from 8.2 ± 6.4 days to 15.2 ± 11.9 days; P = 0.04). At 3 months postoperative, the single assessment numeric evaluation score (80 ± 11% vs 70 ± 6%; P = 0.04) and active elevation (130 ± 22° vs 109 ± 24°; P = 0.01) were higher in the SSCS group. The SSCS approach resulted in a net cost savings of $5900 per patient. Postoperative physical therapy, pain levels, and patient satisfaction were comparable in both groups. No immediate intraoperative complications were noted.ConclusionUsing a SSCS approach is an option for patients requiring RSA. Overall LOS is minimized compared to a TDP approach with subscapularis tenotomy. The SSCS approach may provide substantial healthcare cost savings, without increasing complication rate or decreasing patient satisfaction.
Shoulder apprehension is related to changes in functional cerebral networks induced by dislocations, peripheral neuromuscular lesions and persistent mechanical glenohumeral instability consisting of micro-motion.All the damage to the osseous and soft-tissue stabilizers of the shoulder, as well as neurologic impairment persisting even after stabilization, must be properly identified in order to offer the best possible treatment to the patient.There is growing evidence supporting the use of a global multimodal approach, involving, on the one hand, shoulder ‘reafferentation’, including proprioception, mirror therapy and even cognitive behavioural approaches, and, on the other hand, surgical stabilization techniques and traditional physical therapy in order to minimize persistent micro-motion, which may help brain healing. This combined management could improve return to sport and avoid dislocation arthropathy in the long term.Cite this article: EFORT Open Rev 2018;3:550-557. DOI: 10.1302/2058-5241.3.180007
Introduction. Intramuscular myxoma is a rare benign primitive tumor of the mesenchyme founded at the skeletal muscle level; it presents itself like an unpainful, slow-growing mass. Myxomas with bone lysis are even more rare; only 7 cases have been reported in the English literature, but never at the shoulder level. Case Presentation. We describe an 83-year-old patient with a growing mass in the deltoid muscle with unique scapular lysis, without any symptom. Magnetic resonance imaging (MRI) and a biopsy were performed and the diagnosis of intramuscular myxoma has been retained. In front of this diagnosis of nonmalignant lesion, the decision of a simple follow-up was taken. One year after this decision, the patient was still asymptomatic. Conclusion. In the presence of an intramuscular growing mass with associated bone lysis, intramuscular myxoma as well as malignant tumor should be evoked. MRI has to be part of the initial radiologic appraisal but biopsy is essential to confirm the diagnosis. By consensus, the standard treatment is surgical excision but conservative treatment with simple follow-up can be an option.
