The spring ligament recess is a synovium-lined, fluid-filled space that communicates with the talocalcaneonavicular joint. The recess should be distinguished from a tear of the plantar components of the spring ligament.

Children with clinically suspected VP shunt failure should proceed directly to cross-sectional or nuclear imaging, as plain radiographic examinations have low sensitivity and significant false-negative rates for detecting shunt abnormalities in all-comers. Use of the shunt series should be limited to patients who specifically have suspected mechanical causes of shunt failure.

Symptomatic degenerative joint disease of the first carpometacarpal (CMC) joint has been successfully managed with various surgical treatments including trapeziectomy alone, trapeziectomy and ligament reconstruction with or without tendon interposition, metacarpal osteotomy, CMC arthrodesis, and CMC prosthetic arthroplasty; currently, no single approach has shown superiority. Clinical Relevance The aim of this case report was to cite an occurrence of EPL rupture following its use and discuss the possibilities of its direct contribution.

Mycobacterium avium intracellulare (MAI) infections of the hand, wrist, and upper extremity are rare, but potentially devastating atypical mycobacterial infections that can affect tendon, bone, and other soft tissues of the musculoskeletal system. We present an immunocompromised patient presenting with acute swelling and pain in the dorsum of the hand and wrist that underwent a wrist extensor tenosynovectomy with intraoperative cultures revealing infection with MAI. The patient developed severe progression of the infection with osteomyelitis of the distal forearm and carpal bones, multiple subsequent extensor tendon ruptures, and dorsal skin necrosis. The infection was eradicated with a combination of surgical treatment and antibiotic therapy. The case is discussed in context of the prior scant literature of infectious tenosynovitis of the hand, wrist, and upper extremity caused by MAI. This case report and literature review outline recommendations for diagnosis and effective treatment of MAI.
