Clawing Of Toes

Clawing of toes which mean flexion contraction of proximal interphalangeal joint (PIP) and distal interphalangeal joint (DIP) of toes and extension contraction of metatarsophalangeal joint (MTP) is usually a feature of neuromuscular disorders of musculoskeletal system like charcott mary tooth, poliomyelitis and cerebral palsy. Clawing of this type is an intrinsic muscle injury. Intrinsic muscles of foot are dorsal and plantar interosseous muscles and lumbricals which naturally because of their attachments to tendons of toes, can flex MTP joint and extend DIP and PIP joints. So, if they are nonfunctional because of primary muscle disease or muscle dysfunction secondary to lack of their nerve supply (traumatic or nerve disease), the resultant imbalance of flexors and extensors of toes.
