S62.145 Nondisplaced fracture of body of hamate [unciform] bone, left wrist

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, left wrist

Summary

This condition refers to a break or crack in the body of the hamate bone, one of the small carpal bones in the left wrist, without displacement of bone fragments. The hamate is located on the ulnar (pinky) side of the wrist and contributes to wrist stability and grip function. Fractures in this area typically result from trauma and may vary in severity, with nondisplaced fractures generally involving less structural disruption.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a crushing injury. High-impact activities or accidents may also lead to fractures in this specific bone.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.

Symptoms

• Pain, swelling, and tenderness in the ulnar side of the left wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the wrist and promote healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if conservative treatment fails.

Prognosis and Follow-Up

Most nondisplaced fractures of the hamate bone heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed. Full recovery may take several weeks to months, depending on the individual case.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon irritation due to swelling or bone fragments (rare in nondisplaced cases).

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as wrist guards in sports.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury, or if symptoms worsen despite home care.

Tips for Medical Coders

Document the specific location (left wrist) and fracture type (nondisplaced) to ensure accurate coding. Include details about the mechanism of injury, imaging results, and treatment plan to support the diagnosis.
