dorsal blocking splint
A hand splint that blocks extension while allowing controlled flexion, commonly used after flexor tendon repair to protect the healing tendon.
Full Definition
A dorsal blocking splint is a therapeutic device positioned on the back of the hand and forearm that prevents full extension of the fingers while permitting controlled flexion movements. This splinting technique is essential in post-operative management of flexor tendon repairs, as it maintains the tendon in a relaxed position while allowing early protected motion. The splint typically holds the wrist in slight flexion and the metacarpophalangeal joints in flexion, creating a protective environment for healing tendons while preventing gap formation at the repair site.
Usage
Usage note: Always specify 'dorsal' to distinguish from other blocking splint types.
