Bone injuries: treatment and rehabilitation.

Solid bony union with full range of painless motion is accomplished by correct early diagnosis, adequate reduction, stable fixation, prevention of edema, and institution of early motion programs. The degree of bony injury and involvement of multiple tissues will dictate the type of fixation and length of immobilization. Restoration of a stable skeleton with a functional range of joint motion must always be accomplished.

Low profile dynamic splinting of the injured hand.

Dynamic splinting is a well-accepted modality in gaining joint motion in the injured hand. Presented is a splinting design system referred to as "low profile" dynamic splinting whereby high outriggers are avoided. A review of the literature reveals that this technique is based on the original design approach used by Dr. Sterling Bunnell. Described are the basic principles of the low profile design system, with illustrations of the system in specific splints and specific construction details. This splinting system is indicated for a stiff hand that has sustained direct trauma. Hands with a muscle imbalance secondary to a central nervous system or peripheral nerve lesion require a different splinting approach, which is not within the scope of this paper.

The biomechanics of a thumb carpometacarpal immobilization splint: design and fitting.

Splinting for the common osteoarthritis of the carpometacarpal (CMC) joint of the thumb is infrequently described in the literature, but the few splints that are described include one or both adjacent joints. This paper describes the design and biomechanics of a custom-molded thumb CMC immobilization splint that excludes the thumb metacarpophalangeal and wrist joints. The problem of the imbalance of extrinsic extensor/abductor forces against the intrinsic flexor/adductor forces is described. The accompanying weakening of the thumb CMC capsule allows dorsal shifting of the proximal end of the metacarpal, producing pain. The splint described in this paper 1) prevents motion of the first metacarpal in relation to the other metacarpals, 2) prevents tilting (flexion) of the first metacarpal during pinch, and 3) allows unrestricted thumb metacarpal and wrist joint motion. Attention to detail during construction is required for an accurate pattern, precise positioning of the CMC joint during molding, accurate molding around the first metacarpal, and well-distributed pressure. This design may also be used for protection following thumb CMC arthroplasty or thumb CMC sprain or strain and as a base for thumb metacarpophalangeal and/or interphalangeal mobilization splinting.
