A peripheral nerve lesion occur to the median, radial, & ulnar nerves. The location of the lesion determines the impairment of sudomotor, vasomotor, muscular, sensory, & functional involvement.
There are four procedures used to surgically repair nerves.
- 1. decompression- most common - carpal tunnel release- decompressing the median nerve.
- 2. repair
- 3. neurolysis
- 4. grafting
The purpose for splinting an extremity that has nerve injury are to protect, prevent contractures (short oppenens splint) of the tyhumb web space after a median nerve injury.& assistance with function.
Clawhand deformity results from a ulnar nerve injury. The splint used for this is a mobilizing ulnar gutter splint to remodel the soft tissues to increase passive extension of the ring & little fingers.
Wrist drop & radial tunnel syndrome are caused from radial nerve injury. Splint intervention would be the Long-arm elbow & wrist splint elbow flexion of 90 degrees and slight wrist extension 20-30 degrees in flexion.
