Hand immobilization splints l Two types of positions are accomplished by this splint depending on diagnostic indication 1. Functional position 2. Anti-deformity (intrinsic-plus) position
Functional position l The resting splint is positioned in resting or mid-joint position l Place the wrist in 20 -30 degrees of extension l Thumb CMC in 45 degrees of palmar abduction l Fingers MCP joints 35 -45 degrees of flexion l PIP and DIP of fingers joints in slight flexion
Anti deformity position Often used to place the hand to maintain l tension/distraction of anatomic structure To avoid contractures and promote l function l Wrist: 30 -40 ext l Thumb: 40 -45 palmar abduction l Thumb IP: in full ext l MCPs: 70 -90 flex and PIPs and DIPs in full l ext.
Diagnostic indications Condition Wearing schedule Splint, wrist position RA Worn until exacerbation is over. Wrist: 20 -30 ext. MCP: 15 -20 flex. Thumb: comfort.
