The Short Thumb Spica splint is indicated for arthritis affecting which joints?

• A. Arthritis of CMC and MP joints of thumb
• B. Carpal tunnel syndrome
• C. De Quervain's tenosynovitis
• D. Radial nerve injury

Answer: (A)

The short thumb spica splint is used to immobilize the base of the thumb, specifically limiting motion at the carpometacarpal (CMC) joint and the first metacarpophalangeal (MCP) joint. By stabilizing these joints, it provides rest and pain relief for basilar thumb arthritis, which most commonly involves the CMC joint and can involve the MCP as well. It’s not aimed at nerve issues like carpal tunnel syndrome, nor is it focused on tendon problems like De Quervain’s, which are different pathologies, even though a thumb spica can be used for them in other contexts. So the joints affected by arthritis that this splint targets are the CMC and MCP joints of the thumb.
