Synovial chondromatosis of the flexor hallucis longus tendon sheath.

This case report discusses a rare case of secondary tenosynovial chondromatosis of the flexor hallucis longus (FHL). Synovial chrondomatosis is a rare, benign proliferative cartilaginous lesion arising from the synovial tissue or bursal lining of or near joints. When it is extra-articular, it is considered tenosynovial chondromatosis. The diagnosis is often delayed given the rarity of presentation and non-specific symptoms. The case was highly unusual in that hindfoot pain was caused by several centimetre-sized osteochondral bodies within the FHL tendon sheath. Anterior cheilectomy was performed. The patient returned to full activity following surgery without recurrence of the disease. The condition can be successfully treated operatively.

Bony Edema and Clinical Examination Findings Predict the Need for Distal Clavicle Excision at the Time of Shoulder Arthroscopy.

Background: Deciding to perform a distal clavicle excision for acromioclavicular joint arthritis, especially in conjunction with other arthroscopic shoulder procedures, is challenging for surgeons. Studies have reported mixed results on the value of magnetic resonance imaging (MRI) in decision making. Purpose: We sought to correlate MRI findings with clinical symptoms and the surgeon's decision to perform a distal clavicle excision. Methods: We compared MRI, clinical examination, and MRI findings of 200 patients who underwent distal clavicle excision for symptomatic acromioclavicular joint arthritis with 200 patients who underwent arthroscopic shoulder procedures for other reasons. Univariate statistics were used to determine correlations between physical examination findings, MRI findings, and the decision to perform distal clavicle excision. A binary logistic regression model was used to determine independent predictors of need for distal clavicle excision. Results: There was no difference in mean age, sex, and race between groups. Advanced acromioclavicular joint osteoarthritis was strongly correlated with positive physical examination findings. Bony edema correlated strongly with tenderness at the acromioclavicular joint but not pain with cross-body adduction testing. There was no association between higher MRI grade of osteoarthritis and the need for distal clavicle excision. Regression analysis identified both physical examination findings and bony edema on MRI as independent predictors of the need for distal clavicle excision. Conclusion: In the setting of positive clinical examination findings and bony edema of the distal clavicle, surgeons should feel reassured that distal clavicle excision is likely indicated.

A Novel Surgical Technique for Glenoid Reconstruction in the Trauma Setting With a Distal Tibia Allograft: A Case Report.

CASE: A 21-year-old woman presented with a chronic fracture dislocation of her left shoulder after striking a submerged tree during a watersport activity. She was initially treated at an outside hospital, where she underwent open reduction and internal fixation of her posterior scapula. She presented 8 weeks after index procedure with pain and severely decreased range of motion. Her comminuted and displaced fracture comprising 70% of the anterior superior glenoid was surgically reconstructed using a distal tibia allograft (DTA), resulting in a functional shoulder. CONCLUSION: A DTA is a feasible option to reconstruct the glenoid surface in fracture dislocations of the shoulder with a significant loss of the articular surface.
