ICD-10: S63.437

The ICD-10 code S63.437 specifically refers to a traumatic rupture of the volar plate of the left little finger, affecting both the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This condition is characterized by the tearing of the volar plate, a fibrous structure located on the palmar side of the finger joints, which plays a crucial role in stabilizing the joints and preventing hyperextension.

Clinical Description

Anatomy and Function

The volar plate is a thickened ligamentous structure that connects the proximal phalanx to the middle phalanx at the MCP and IP joints. It serves several important functions:
- Stabilization: It helps stabilize the joints during flexion and extension.
- Prevention of Hyperextension: The volar plate prevents excessive backward bending of the finger joints.
- Facilitation of Motion: It allows for smooth movement of the finger during grasping and manipulation tasks.

Mechanism of Injury

A traumatic rupture of the volar plate typically occurs due to:
- Acute Trauma: This can result from a fall, direct impact, or sports-related injuries where the finger is forcibly bent backward (hyperextended).
- Chronic Stress: Repetitive stress or overuse can also lead to gradual weakening and eventual rupture of the volar plate.

Symptoms

Patients with a traumatic rupture of the volar plate may experience:
- Pain and Swelling: Localized pain at the MCP and IP joints, often accompanied by swelling.
- Instability: A feeling of instability in the little finger, particularly during movement.
- Limited Range of Motion: Difficulty in fully extending or flexing the finger.
- Deformity: In some cases, a visible deformity may be present, especially if the injury is severe.

Diagnosis

Diagnosis of a volar plate rupture typically involves:
- Clinical Examination: Assessment of pain, swelling, and range of motion.
- Imaging Studies: X-rays may be performed to rule out fractures, while MRI can provide detailed images of soft tissue injuries, including the volar plate.

Treatment

Treatment options for a traumatic rupture of the volar plate may include:
- Conservative Management: This often involves rest, ice, compression, and elevation (RICE), along with splinting to immobilize the finger.
- Physical Therapy: Rehabilitation exercises may be recommended to restore strength and flexibility once the initial pain and swelling subside.
- Surgical Intervention: In cases of complete rupture or significant instability, surgical repair may be necessary to restore function and stability to the joint.
