ICD-10: S93.123

The ICD-10 code S93.123 refers specifically to the dislocation of the metatarsophalangeal joint of the unspecified great toe. This condition is categorized under the broader classification of dislocations and sprains of the foot and toes, which are common injuries that can occur due to various factors such as trauma, sports activities, or accidents.

Clinical Description

Definition

A dislocation of the metatarsophalangeal joint occurs when the bones of the joint are displaced from their normal alignment. In the case of the great toe, this joint connects the first metatarsal bone of the foot to the proximal phalanx of the toe. Dislocations can be complete or partial, with complete dislocations involving total displacement of the joint surfaces.

Symptoms

Patients with a dislocated metatarsophalangeal joint may experience:
- Severe pain: Often immediate and intense at the site of injury.
