S62.212 Bennett's fracture, left hand

Name of the Condition

• Bennett's fracture, left hand

Summary

This condition is a specific type of fracture involving the base of the first metacarpal bone in the left hand, typically occurring at the joint surface and potentially involving displacement of bone fragments. The fracture often affects the carpometacarpal joint, leading to instability that may require careful management to preserve thumb function.

Causes

Commonly caused by direct trauma, such as a forceful impact to the thumb or a fall onto an outstretched hand. This type of injury is frequently associated with activities that place stress on the thumb, including sports or manual labor.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous hand or thumb injuries that may have compromised bone integrity.

Symptoms

• Pain, swelling, and tenderness at the base of the left thumb.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent, including any joint involvement or displacement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the thumb and promote healing.
• Closed reduction: Manual realignment of displaced bone fragments without surgery.
• Surgical intervention: Internal fixation with pins, screws, or plates for unstable or severely displaced fractures.
• Rehabilitation: Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper treatment. Prognosis depends on the severity of displacement and adherence to immobilization or surgical protocols. Follow-up imaging may be required to assess healing, and physical therapy is often recommended to regain full function.

Complications

• Arthritis: Long-term joint damage or degenerative changes due to intra-articular involvement.
• Chronic pain: Persistent discomfort, especially with movement.
• Stiffness or reduced mobility: Limited thumb function if rehabilitation is incomplete.
• Nonunion or malunion: Failure of the bone to heal properly or heal in a misaligned position.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by using assistive devices if balance is impaired.
• Practice proper hand positioning during activities to reduce stress on the thumb.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, warmth, fever) after an injury.

Tips for Medical Coders

Document the specific hand (left) and any additional details, such as fracture displacement, treatment type, or encounter stage, to ensure accurate coding. Note the anatomical location and clinical findings to support the diagnosis.
