Contractures of the intrinsic muscles of the fingers disrupts the delicate and complex balance of the intrinsic and extrinsic muscles. Sometimes, it is called Intrinsic Plus Hand. The hand assumes a posture with a hyper flexed metacarpophalangeal MCP joint and a hyperextended proximal interphalangeal PIP joint. Contracted interossei and lumbrical muscles deform the natural cascade of the fingers. Severe disability may result because of weakness in grip and pinch strength as well as difficulty in grasping large objects.

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

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.

Intrinsic hand deformities represent a challenging condition that disables the patient if left untreated. A thorough physical examination is essential to find the cause of this condition. Nerve repairment and transfers, as well as tendon transfers, have the potential to restore grip and pinch. This activity reviews the evaluation and treatment of intrinsic hand deformities and highlights the role of the healthcare team in evaluating and treating patients with intrinsic hand deformities.

Topic Podcast. No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article. A thorough physical examination is essential to find the cause of this condition. Objectives: Describe the presentation of a patient with an intrinsic hand deformity. Ulnar neurectomy: Indicated in cases with spasticity. Nonfunctioning intrinsics may be completely released or denervated. Other causes include nervous entrapment along its path in the arm compression neuropathy , compartment syndrome, central nervous system diseases, rheumatoid diseases, Leprosy Hansen disease , rheumatoid arthritis, Charcot-Marie-Tooth disease, and prolonged immobilization, failure to splint a crush-injured hand using intrinsic plus posture. The success of this procedure depends largely on postoperative management and careful evaluation of the hand disorder. J Hand Microsurg. Intrinsic contracture is not passively correctable. For example, placing the MCPJ into radial deviation during the test would further tighten the ulnar-side intrinsic tendons.

Please note that the little finger has a slight variation in horizontal movements. Nerve repairment and transfers, as well as tendon transfers, have the potential to restore grip and pinch. Carpal tunnel syndrome CTS is the most common entrapment neuropathy with an incidence of 1 to 3 persons per person-years. Thus, MCP joint hyperextension tightens the intrinsic muscles. Prolonged delays increase the chance to need nerve grafting, fibrosis of the stump, and neuron loss. About the author PlasticsFella. Their insertion points differ. Related information. Severe contracture was observed in all digits, including the thumb, and the condition was very similar to that of clenched fist syndrome. Received Nov 24; Accepted May 6.
