What are the indications and outcome of Splinting?
@donald Indications for splinting include the following:
Temporary immobilization of sprains, fractures, and reduced dislocations
Control of pain
Prevention of further soft-tissue or neurovascular injuries
The American Academy of Orthopaedic Surgeons (AAOS) found strong evidence to support the use of splints in the treatment of carpal tunnel syndrome (CTS).
Although splinting is a common initial treatment for CTS, the evidence of its efficacy as a standalone treatment is weak.  Electrophysiologic assessment is under investigation as a tool to aid in the selection of patients who would receive the greatest benefit from splinting.
A study of nighttime splinting for 6 weeks as treatment for recent onset idiopathic trigger fingers reported complete resolution of symptoms in 55% of patients. A thumb spica splint relieves the symptoms of de Quervain tendinopathy, but symptoms improve more rapidly when it is combined with corticosteroid injection.
A comparison of wrist-joint splinting combined with physical therapy and physical therapy alone for the treatment of lateral epicondylitis ("tennis elbow") found significantly greater improvement in pain intensity, wrist flexion range of motion, and grip strength.
