The Effect of a Wrist Brace on Injury Patterns

We compared patterns of bony and ligamentous injury with distal radial fractures in braced and unbraced wrists using 20 paired fresh cadaveric upper extremi ties. A commercially available wrist brace was placed on one wrist in each pair. Specimens were then placed in a fast-loading gravity-driven device and subjected to loads averaging 16 kg from an average height of 78 cm. Postfracture radiographs were obtained, the spec imens were dissected, and fracture patterns and liga mentous integrity were assessed. The following frac ture types were produced: distal radial fractures (eight unbraced, seven braced) and intraarticular (seven un braced, four braced). Radiographically, seven un braced wrists demonstrated carpal bone fracture and one braced wrist demonstrated carpal fractures. Eight unbraced and three braced wrists sustained carpal intrinsic ligament injuries, four unbraced and one braced wrists demonstrated extrinsic ligament injuries. More capsular tears occurred in the unbraced group (N = 8) than in the braced group (N = 1). This model demonstrated a difference in the patterns of injury in unbraced and braced wrists subjected to the same mechanical conditions, which suggests that use of a wrist brace may alter patterns of wrist injury.

Braces and splints can be useful for acute injuries, chronic conditions, and the prevention of injury. There is good evidence to support the use of some braces and splints; others are used because of subjective reports from patients, relatively low cost, and few adverse effects, despite limited data on their effectiveness. The unloader (valgus) knee brace is recommended for pain reduction in patients with osteoarthritis of the medial compartment of the knee. Use of the patellar brace for patellofemoral pain syndrome is neither recommended nor discouraged because good evidence for its effectiveness is lacking. A knee immobilizer may be used for a limited number of acute traumatic knee injuries. Functional ankle braces are recommended rather than immobilization for the treatment of acute ankle sprains, and semirigid ankle braces decrease the risk of future ankle sprains in patients with a history of ankle sprain. A neutral wrist splint worn full-time improves symptoms of carpal tunnel syndrome. Close follow-up after bracing or splinting is essential to ensure proper fit and use.

Family physicians often must make decisions regarding the use of braces or splints in the management of musculoskeletal disorders. Bracing can be useful for acute injuries, and also for chronic conditions and in the prevention of injury. The purpose of braces and splints is to improve physical function, slow disease progression, and diminish pain. They can be used to immobilize an unstable joint or fracture, to unload a portion of a joint and improve pain and function, to eliminate range of motion in one direction, or to modify range of motion in one or more directions. They do not replace a good rehabilitative program, and the entire spectrum of treatment options should be explored and used as needed.

Accurate diagnosis of the injury is important in determining whether a brace or splint is indicated. Generally, splints are for short-term use. Excessive, continuous use of a brace or splint can lead to chronic pain and stiffness of a joint or to muscle weakness. However, long-term use of some braces, such as a knee support, can help prevent progression of pain attributable to osteoarthritis of the knee.
