S52.601 Unspecified fracture of lower end of right ulna

Name of the Condition

• Unspecified fracture of lower end of right ulna

Summary

This condition involves a fracture at the lower end of the right ulna, a bone in the forearm, with unspecified details about displacement or type. The lower end of the ulna is near the wrist joint, and fractures here can affect stability and function. Documentation should specify whether the fracture is displaced, open, or closed if known, as this impacts treatment and coding.

Causes

Fractures of the lower ulna typically result from trauma, such as falls onto an outstretched hand, direct blows to the wrist, or high-impact injuries like motor vehicle accidents. The mechanism often involves force transmitted through the wrist, leading to a break in the bone.

Risk Factors

• Participation in contact sports or activities with a high fall risk
• Osteoporosis or reduced bone density
• Advanced age, which may weaken bone resilience
• Previous wrist or forearm injuries
• Occupations or hobbies involving repetitive stress or heavy lifting

Symptoms

• Pain and tenderness at the wrist or forearm
• Swelling, bruising, or visible deformity near the injury site
• Limited range of motion in the wrist or elbow
• Possible numbness or tingling in the hand or fingers
• Difficulty bearing weight or using the affected arm

Diagnosis

Diagnosis is confirmed through physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to identify the fracture, its location, and any displacement. Additional tests may be ordered if nerve or vascular involvement is suspected.

Treatment Options

• Immobilization with a cast or splint to stabilize the bone and promote healing
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and range of motion once healing progresses
• Surgical intervention if the fracture is displaced, unstable, or involves other structures

Prognosis and Follow-Up

With proper treatment, most fractures heal within 6–8 weeks, though recovery may vary based on severity. Follow-up appointments are necessary to monitor healing and adjust treatment. Full function often returns, but stiffness or weakness may persist temporarily.

Complications

• Nonunion or delayed healing of the fracture
• Malunion, where the bone heals in an incorrect position
• Nerve or blood vessel damage near the injury site
• Chronic pain or arthritis in the wrist joint
• Infection (if the fracture is open)

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities
• Maintain bone health through a balanced diet and weight-bearing exercise
• Improve balance and reduce fall risk, especially in older adults
• Avoid repetitive stress on the wrist or forearm when possible

When to Seek Professional Help

• Severe pain that does not improve with rest or medication
• Visible deformity or bone protrusion through the skin
• Numbness, tingling, or loss of circulation in the hand
• Inability to move the wrist or fingers
• Signs of infection, such as redness, warmth, or pus at the injury site

Tips for Medical Coders

• Ensure documentation specifies whether the fracture is displaced, open, or closed, as this affects code assignment. For this code, the term "unspecified" indicates details about displacement or type are not documented. If more information becomes available, update the code to reflect the specific fracture characteristics. Verify laterality (right ulna) and anatomical site (lower end) are clearly documented to support accurate coding.
