Abstract

Much of the hand's inherent functionality can be attributed to a delicate balance between the intrinsic and extrinsic musculature. Injury to or compromise of the intrinsic musculature can lead to the development of an intrinsic minus (claw) or intrinsic plus (contracture) hand. If left untreated, these deformities may cause profound functional limitations, including digital and wrist stiffness, impaired grip strength, an inability to grip objects properly, and challenges with personal hygiene. A thorough history and physical examination are typically sufficient to diagnose intrinsic hand deformity. Additional imaging, laboratory tests, and neurological studies may be indicated to establish an underlying etiology. While nonoperative management, such as bracing, therapy, and injections, may be adequate interventions in milder cases, more advanced deformities may require operative treatment.
