S62.145A Nondisplaced fracture of body of hamate [unciform] bone, left wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, left wrist, initial encounter for closed fracture

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 involving intact alignment of bone fragments.

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: Medications or therapies to reduce discomfort and inflammation.
• Rehabilitation: Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments monitor healing progress, and rehabilitation may be recommended to restore full function. Recovery time varies but typically ranges from several weeks to a few months, depending on the individual's health and adherence to treatment.

Complications

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

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., wrist guards in sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by improving balance and removing tripping hazards at home.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the wrist, visible deformity, or signs of infection (e.g., fever, increased swelling, redness).

Tips for Medical Coders

Document the specific location (left wrist), fracture type (nondisplaced), and encounter details (initial, closed) to ensure accurate coding. Include clinical notes confirming the absence of displacement and the nature of the fracture (e.g., imaging reports, physical exam findings) to support the code assignment.
