Hand immobilization splints Volar based resting hand splint is better used when you require a great amount of forearm support Dorsally based RHS is used when there is sutures, sores, rashes, or intravenous needles. Also used for someone who has hypertonicity
9
Hand immobilization splints Two types of positions are accomplished by this splint depending on diagnostic indication 1.Functional position 2.Anti-deformity (intrinsic-plus) position
10
Functional position The resting splint is positioned in resting or mid-joint position Place the wrist in 20-30 degrees of extension Thumb CMC in 45 degrees of palmar abduction Fingers MCP joints 35-45 degrees of flexion PIP and DIP of fingers joints in slight flexion
11
Anti deformity position Often used to place the hand to maintain tension/distraction of anatomic structure To avoid contractures and promote function Wrist: 30-40 ext Thumb: 40-45 palmar abduction Thumb IP: in full ext MCPs: 70-90 flex and PIPs and DIPs in full ext.
12
Diagnostic indications ConditionWearing scheduleSplint, wrist position RAWorn until exacerbation is over. Wrist: 20-30 ext. MCP: 15-20 flex. Thumb: comfort. Hand burns Dorsal or volar Continuously worn until healing begin, removed for dressing changes, therapy, and hygiene. Wrist: (V) 30-40 ext. Wrist: (D) 0 ext. MCP: 70-90 flex. PIP, DIP full ext Thumb: palmar abd & ext. Burn acute phase Worn all time except for therapy. As ROM improves decrease wearing time. Same as above. Burn: Skin graft Worn all times for 5 days!Antideformity. 12

Diagnostic indications ConditionWearing scheduleSplint, wrist position Burn: rehab phase.Only at night time.Antideformity. Dupuytren’sAfter surgery, worn at night times, removed for hygiene and exercise. Wrist: neutral or slight extension. MCPs, PIPs, & DIPs: full extension. Crush injuries of the hand At night, or periods of pain Wrist: 0-30 ext. MCP: 60-80 flex. Thumb: palmar abduction & extension. CRPSAll times, removal for hygiene and ADL. Weaned with decreseaed pain and improved function considering comfort 20 degrees wrist ext, thumb palmar abd, MCP: 70 flex, PIP: 0- 10 flex 13
