Focused, radial and combined shock wave therapy in treatment of calcific shoulder tendinopathy.

Objective: The aim of this work is to compare the clinical, functional, and ultrasonographic outcomes of focused, radial, and combined extracorporeal shock-wave therapy (ESWT) in the treatment of calcific shoulder tendinopathy.Methods: we enrolled 45 patients with calcific shoulder tendinopathy, their ages ranged from 30 to 68 (50.93 ± 9.44) years, classified according to the line of treatment into three groups, all received four sessions of ESWT 1 week apart.Group I: 15 patients received focused shock waves (F-SW) 1500 shocks.Group II: 15 patients received radial shock waves (R-SW) 2000 shocks.Group III: 15 patients received combined focused and radial shock waves (C-SW). All patients were evaluated by musculoskeletal ultrasound (MSK US) before treatment, at 1 week and at 3 months after the last session.Results: In the three studied groups, there was a significant improvement in shoulder pain, active range of motion (ROM), and shoulder function by shoulder disability questionnaire (SDQ) at 1 week after the end of treatment and after 3 months follow up. Moreover, there was a significant sonographic reduction in calcification size in the three groups. At the end of the study, the best improvement as regards a decrease of calcification size was obtained in group III when compared with group I and group II.Conclusion: These results demonstrated clinical, functional, and sonographic improvement in all groups. The best therapy in calcific shoulder tendinopathy appears to be combined focused and radial ESWT compared to interventions alone. Level 1 Evidence Randomized control study.

Intra-articular injection of etanercept versus glucocorticoids in rheumatoid arthritis patients.

OBJECTIVES: This study was conducted to assess the safety and efficacy of intra-articular injection of etanercept and compare it with corticosteroid injection in rheumatoid arthritis (RA) patients. METHODS: Fifty patients with RA who suffered from activity in one joint were randomized into two groups, received an intra-articular injection of either etanercept or corticosteroid guided by musculoskeletal ultrasound. All patients were assessed for disease activity by disease activity score (DAS28), functional assessment using the Modified Health Assessment Questionnaire (MHAQ), and laboratory investigations (erythrocyte sedimentation rate and C-reactive protein). Joints affected were evaluated for pain by visual analog scale (VAS), tenderness, and swelling scores and by ultrasound for estimation of synovial hypertrophy, synovial effusion, and power Doppler. Follow-up of the patients was done at weeks 1, 4, and 12 after injection by clinical assessment and ultrasound. RESULTS: There was a significant improvement of joint pain assessed by VAS, tenderness, and swelling scores in the etanercept group at week 1 and week 4 follow-up periods but there were insignificant changes at week 12. There was a significant decrease in synovial effusion at week 1 and week 4 and in power Doppler at week 1 but no significant change was noticed in synovial hypertrophy during the follow-up periods. In comparison of the two groups, etanercept has shown better results on joint scores at week 1; however, glucocorticoid had more sustained effects. No major or life-threatening side effects were noticed following intra-articular injection of etanercept. CONCLUSION: Intra-articular injection of etanercept is a safe and promising option; with comparable results to intra-articular injection of corticosteroid; however, its rapid absorption from the synovium may necessitate frequent injections. Key Points • Persistent inflammatory mono-arthritis is a common clinical problem that is often difficult to treat; it is a debilitating and destructive condition. • Intra-articular injection of TNF inhibitors is an encouraging treatment modality in managing refractory mono-arthritis in rheumatoid arthritis.

Ulnar Nerve Injuries (Sunderland Grade V): A Simplified Classification System and Treatment Algorithm.

This study introduced a novel technical approach to the ulnar nerve injuries. The ulnar nerve was divided into 4 distinct surgical zones, each mandating a unique management strategy. METHODS: A prospective observational study was conducted to verify the hypothesized algorithm. The study included 110 patients diagnosed with ulnar nerve injury (Sunderland grade 5). We divided the patients into 4 groups depending on the site of injury. Each group of patients was managed in accordance with a particular strategy, exploiting nerve transfer techniques along with the updated knowledge of the internal topography of the ulnar nerve. The motor recovery of the small muscles of the hand was assessed after 2 years of follow-up, using the disabilities of the arm, shoulder, and hand score, and other parameters including key pinch strength, hand grip strength, and the motor power of the first dorsal interosseous muscle on the Medical Research Council scale. RESULTS: The mean values of the disabilities of the arm, shoulder, and hand score, key pinch strength, and hand grip strength showed a statistically significant improvement across all patient groups (P < 0.05). Of those with zone (I) injury, postoperatively, 79.9% patients attained a first dorsal interosseous muscle power grade >3 on the Medical Research Council scale, while 93.9% of patients with zone (II) damage achieved the same result. Surprisingly, 84% of patients included in both zones (III) and (IV) also recovered to the same extent. CONCLUSIONS: This prospective observational study examined and successfully confirmed the validity of our proposed novel algorithm for the management of ulnar nerve injuries (Sunderland grade 5).
