There is a well-documented association between carpal tunnel syndrome (CTS) and thumb carpometacarpal (CMC) arthritis, and these conditions commonly coexist. We have observed that patients who have previously undergone thumb basal joint arthroplasty (BJA) seem rarely to present subsequently with CTS. Our hypothesis is that BJA decreases the pressure within the carpal tunnel. ⋯ Level II, diagnostic.

There is no robust evidence of the best operative treatment for displaced unstable metacarpal neck fractures. Numerous constructs are used in the fixation of metacarpal neck fractures. Currently, two common methods are dorsal locking plate and K-wire fixation. A new metacarpal sled fixation system for metacarpal neck fracture was designed to provide fracture stability but limit dissection and avoid exposed hardware. The purpose of this study was to compare the biomechanical integrity of the metacarpal sled versus standard locking plate fixation and retrograde K-wire fixation in a simulated porcine metacarpal fracture model. ⋯ For transverse metacarpal neck fractures, a metacarpal sled construct provides similar fixation to K-wires with limited dissection and without exposed hardware or the potential for soft tissue tethering. The new low profile construct using a minimally invasive technique would be suitable for unstable metacarpal neck fractures.

Routine use of locking shaft screws is not necessary in volar plate fixation of distal radius fractures.
Volar locking plate fixation is a common treatment method for distal radius fractures. Recently, implants have been designed with an option to use locking screws in the shaft portion of the plate. While there is a high incidence of low bone mineral density in patients who sustain fragility fractures of the distal radius, the need for locking shaft screws is not well defined. Our hypothesis is that the routine use of locking screws in the shaft portion of volar plates is not required to maintain reduction or to prevent hardware failure. ⋯ Distal radius fractures frequently occur in patients with low bone mineral density. Non-locking, bicortically placed shaft screws provide adequate stability to allow for early range of motion without loss of reduction or hardware failure. The routine use of locking screws in the shaft portion of volar plates does not appear justified.

Compression screw fixation without bone grafting for scaphoid fibrous nonunion.
Bone graft is often recommended as an adjuvant for treatment of scaphoid nonunions. However, recent literature has suggested that fibrous nonunion may be suited to treatment with rigid fixation without bone grafting. This work reported on outcomes of compression screw fixation for established scaphoid fibrous nonunions without bone graft. ⋯ Therapeutic Level IV, retrospective case series.

Coccidioidomycosis causing osteomyelitis of the hand in an immunocompetent patient.
Coccidioidomycosis osteomyelitis is a rare entity considered even more rare when identified in the immunocompetent patient. In non-endemic areas, the diagnosis of a fungus-causing osteomyelitis is often delayed or overlooked. This results in delayed or inappropriate treatment. ⋯ When he failed to improve, he presented for a second opinion. The patient's origin and travel history coupled with the appearance of rapid bone destruction on plain radiographs prompted a second operation for tissue biopsy and culture for bacteria, fungus, and mycobacteria cultures. This case highlights the importance of a thorough clinical history in deriving an appropriate differential diagnosis prior to surgical intervention.
