Functional results of Circumferential Capsular Release in adhesive shoulder capsulitis. Comparative study of patients over and under fifty years of age.

INTRODUCTION: The aim of our study is to evaluate the functional and mobility outcomes in patients who have undergone arthroscopic circumferential arthrolysis of the shoulder and to find out if there are differences in the results in relation to the patient's age. MATERIALS AND METHODS: This is a retrospective case series of patients with idiopathic adhesive capsulitis treated by arthroscopic 360º circumferential capsulotomy in lateral position and followed for a minimum of 2 years. Range of motion (ROM), functional outcomes using the Constant Score (CS), health-related quality of life outcomes with the EuroQol Five Dimensions tool (EQ-5D), pain using the Visual Analogue Scale (VAS). RESULTS: A total of 26 shoulders were included, 10 men (41.7%) and 14 women (58.3%), with 2 patients being bilateral. The mean age was 48.64 ± 7.5 years, and the mean follow-up was 50.2 months. Postoperative ROM improved significantly compared to preoperative ROM (p < 0.05). Shoulder forward flexion improved by 38.6° (95%CI 22.3-54.9, p < 0.01), abduction by 35.2° (95%CI 17.6-52.8, p < 0.01) and external rotation by 21.9° (95%CI 12.8-30.9, p < 0.01 p < 0.01). Median internal rotation improved from buttock to T12 (p < 0.01). The mean improvement in CS was 54.3 ± 24.4 points (p < 0.01). The EQ-5D and VAS scores at the end of follow-up were 0.73 ± 0.23 and 2.73 ± 2.55, respectively. There were no statistical differences between young patients and patients aged 50 years or older in ROM or functional results. CONCLUSIONS: Patient age did not affect outcomes significantly, with patients older than 50 years showing similar results to younger patients.

Which is the function of a martin-gruber connection?

Clinical and diagnostic variations may occur due to the variable presence of a connection between the median and ulnar nerves in the forearm (Martin-Gruber anastomosis). This incidence has a wide range at 7%-40%. Most commonly, the connection between the nerves is considered to be composed of motor fibers; although, a sensory role has also been described. It is important to note that the number of axons, or the nature of the fibers in this connection, have not yet been elucidated. Fifty upper limbs were examined evaluating morphometric characteristics of the Martin Gruber connection, dissected out, sectioned, and immunohistochemically stained for choline acetyltransferase (ChAT) and analyzed with ImageJ© . The connection was observed in 32% of all cases (16/50). The nerve connections were identified as those in Pattern 1 group (12%-type 1b, 19%-type 1a, and 69%-type 1c) and contained motor (ChAT positive) fibers (40.42 ± 10.5% per connection) with three to four fascicles in each. No statistically significant differences were found according to sex, side, or laterality. There were statistically significant differences in the percentages of ChAT positive fibers; however, this was dependent on the distribution being greater in those not distributed zonally. The presence of this connection is prevalent in almost a third of the cadavers dissected; the understanding of this complex composition in sensory and motor fibers allows for the optimization of diagnosis and treatment of certain median-ulnar nerve injuries.

Suspected Brown Recluse Spider Envenomation: Missed Diagnosis and Delayed Treatment of Loxoscelism: A Case Report.

CASE: We report the case of a previously healthy 51-year-old man who presented to our hospital after worsening clinical appearance of his left ring finger, despite antibiotics and previous surgical drainage for suspected abscess at an outside institution 3 weeks ago. He was admitted to our hospital for surgical debridement and decompression. After suspicion of cutaneous loxoscelism based on the clinical record and corticosteroid administration, the patient presented a favorable evolution. CONCLUSION: Cutaneous loxoscelism caused by a spider bite is present in Europe, mainly in the Mediterranean area, and should be considered in cases of skin infections which do not respond to antibiotics.
