Understanding Subluxation of the Metatarsophalangeal Joint

Definition

Subluxation refers to a partial dislocation of a joint, where the bones remain in contact but are not properly aligned. In the case of the metatarsophalangeal joint of the great toe, this condition can lead to pain, instability, and impaired function of the foot.

Clinical Presentation

The diagnosis typically involves the following clinical features:

• Pain and Tenderness: Patients often report localized pain at the site of the joint, which may worsen with movement or weight-bearing activities.
• Swelling and Inflammation: There may be visible swelling around the joint, indicating inflammation.
• Limited Range of Motion: Patients may experience difficulty in moving the toe, particularly in flexion and extension.
• Deformity: In some cases, there may be a noticeable deformity of the toe, which can be assessed during a physical examination.

Diagnostic Criteria

Medical History

A thorough medical history is essential, including:

• Injury History: Documentation of any recent trauma or injury to the toe or foot that could have led to the subluxation.
• Previous Conditions: Information on any prior foot conditions, such as arthritis or previous dislocations, which may predispose the patient to subluxation.

Physical Examination

The physical examination should focus on:

• Inspection: Observing the toe for any deformities, swelling, or discoloration.
• Palpation: Feeling for tenderness, warmth, or abnormal positioning of the joint.
• Range of Motion Tests: Assessing the active and passive range of motion to determine any limitations or pain during movement.

Imaging Studies

While the diagnosis can often be made clinically, imaging studies may be utilized to confirm the diagnosis and assess the extent of the subluxation:

• X-rays: Standard imaging to visualize the alignment of the bones in the joint. X-rays can help rule out fractures and confirm the presence of subluxation.
