S52.331H Displaced oblique fracture of shaft of right radius, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

Displaced oblique fracture of shaft of right radius, subsequent encounter for open fracture type I or II with delayed healing
ICD-10 Code: S52.331H

Summary

A displaced oblique fracture of the shaft of the right radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, with the fracture line running diagonally and the bone fragments misaligned. This code applies to a subsequent encounter for an open fracture type I or II (skin broken but wound small/moderate) where healing is delayed. The injury may affect arm function depending on displacement, angulation, and soft tissue damage, requiring ongoing evaluation and management.

Causes

This fracture typically results from direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can cause the bone to break in an oblique pattern with displacement and skin penetration, leading to delayed healing if not properly managed.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting
• Poor blood supply to the fracture site
• Inadequate initial treatment or immobilization

Symptoms

• Persistent pain at the injury site beyond expected healing time
• Swelling, bruising, or deformity that does not improve
• Limited range of motion in the wrist or forearm
• Visible bone protrusion through the skin (in open fractures)
• Numbness or tingling in the hand or fingers
• Difficulty bearing weight or using the arm

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays to confirm the fracture type, displacement, and healing status. Additional tests like CT scans or MRIs may be used to evaluate soft tissue damage or delayed union. Clinical documentation must specify the fracture type (open I/II), laterality (right), and the presence of delayed healing to support the code.

Treatment Options

Treatment focuses on promoting healing and restoring function. Options may include immobilization with a cast or brace, pain management, physical therapy to improve mobility, and in some cases, surgical intervention to realign the bone or address soft tissue damage. Monitoring for signs of nonunion or malunion is essential, with adjustments to the treatment plan as needed.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and adherence to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up appointments are necessary to assess healing progress, adjust immobilization, and guide rehabilitation. Most patients regain full function with proper care, though some may experience residual stiffness or weakness.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Infection (especially in open fractures)
• Nerve or blood vessel damage
• Chronic pain or arthritis
• Reduced range of motion or strength

Lifestyle & Prevention

• Avoid high-risk activities until cleared by a healthcare provider
• Use protective gear during sports or manual labor
• Maintain bone health through diet and exercise (e.g., calcium, vitamin D)
• Follow post-injury care instructions closely to support healing
• Attend all follow-up appointments to monitor progress

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe or worsening pain
• Increased swelling, redness, or drainage from the wound
• Numbness, tingling, or loss of circulation in the hand
• Inability to move the wrist or fingers
• Signs of infection (fever, chills, foul odor)

Tips for Medical Coders

Document the fracture type (open I/II), laterality (right), and the presence of delayed healing to accurately assign S52.331H. Ensure clinical notes specify "subsequent encounter" and confirm healing status (e.g., delayed union) to support the code. Avoid using this code for initial encounters or closed fractures.
