Intrinsic plus deformity

Definition of Intrinsic Plus. Intrinsic Plus condition is marked by tight interossei and lumbricals muscles causing MCPJ hyperflexion and PIPJ hyperextension, initially identified by Finochietto in and elaborated by Bunnell in Intrinsic Muscle Anatomy. Intrinsic Plus Aetiology. Intrinsic tightness can stem from local issues like fractures or systemic conditions like Rheumatoid Arthritis, affecting the interosseous muscles. Intrinsic Plus Clinical Picture. Non-surgical treatment aims to prevent irreversible contractures, employing methods like elevation, splinting, and manual stretching depending on the joints involved. Surgical Management of the Intrinsic Plus Hand. Chronic tightness can result in contractures and swan-neck deformities. It was described by Finochietto in and later expanded upon by Bunnell in An intrinsic muscle is defined as those having an origin and insertion within the hand. This includes the thenar and hypothenar muscles, interossei , and lumbricals.

While this deformity is often due to direct hand trauma, malnutrition, or ischemia, it can also occur without any obvious causes [ 12 ]. Evidence Evidence. The long term recovery curve in adults after median or ulnar nerve intrinsic plus deformity a reference interval.

The presentation is similar to clenched fist syndrome and it is often associated with various non-psychiatric events such as trauma, malnutrition, and ischemia. It is also often associated with psychiatric pathology. Unlike clenched fist syndrome, its status can worsen over time and result in soft tissue contracture and joint malalignment.

Tip: If the force required to flex the IP increases with f lexion of the MCP , this indicates contracture of the extrinsic extensor. Opponens pollicis is evaluated by the opposition to the fifth finger. Objectives: Describe the presentation of a patient with an intrinsic hand deformity. Deterrence and Patient Education Patient education is very important in hand surgery. Locking of the metacarpophalangeal joint caused by idiopathic intrinsic muscle atrophy of the hand: report of three cases. Management of ulnar nerve injuries. Flexible claw hand has a better prognosis if a procedure aimed at preventing MCP hyperextension is performed. In the patients with simple clawing, tendon transfers correct the MCP joint hyperextension whereas, in complex clawing transfer, the active proximal interphalangeal extension should also be provided. Intrinsic Plus condition is marked by tight interossei and lumbricals muscles causing MCPJ hyperflexion and PIPJ hyperextension, initially identified by Finochietto in and elaborated by Bunnell in In addition, we also discuss the background of intrinsic plus contracture without severe direct trauma of the hand. The intrinsic tightness test was developed by Bunnel in Non-surgical treatment aims to prevent irreversible contractures, employing methods like elevation, splinting, and manual stretching depending on the joints involved.
