S52.621G Torus fracture of lower end of right ulna, subsequent encounter for fracture with delayed healing

Name of the Condition

• Torus fracture of lower end of right ulna, subsequent encounter for fracture with delayed healing

Summary

A torus fracture of the lower end of the right ulna with delayed healing is a stable, incomplete break in the distal portion of the right ulna, characterized by buckling of the bone cortex without significant displacement. This condition occurs during a subsequent encounter for fracture care and indicates that healing is progressing more slowly than expected. The injury typically results from trauma, such as a fall onto an outstretched hand, and may involve minimal soft tissue damage. Treatment focuses on monitoring and supporting healing, with potential adjustments to immobilization or rehabilitation based on progress.

Causes

The most common cause is trauma, such as a fall onto an outstretched hand, a direct blow to the forearm, or a high-impact injury. The force transmitted through the wrist or elbow can lead to buckling of the distal ulna. Delayed healing may result from factors like inadequate immobilization, poor blood supply to the fracture site, or underlying conditions affecting bone healing.

Risk Factors

• Participation in activities with a high risk of falls (e.g., sports, playground activities)
• Pediatric age group, as bones are more flexible and prone to torus fractures
• Osteoporosis or reduced bone density (less common in children but relevant in older populations)
• Previous forearm or wrist injuries
• Certain occupations or hobbies involving repetitive stress or heavy lifting
• Conditions that impair bone healing (e.g., diabetes, smoking, nutritional deficiencies)

Symptoms

• Mild to moderate pain at the injury site, possibly persistent or worsening
• Swelling or tenderness over the distal ulna
• Limited range of motion in the wrist or forearm
• Visible deformity or abnormal contour of the bone (in some cases)
• Delayed return to normal function compared to typical healing timelines

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion, followed by imaging studies such as X-rays to confirm the fracture type and evaluate healing progress. Additional imaging (e.g., CT or MRI) may be used to assess bone union or identify factors contributing to delayed healing. Clinical correlation with the patient’s history and treatment course is essential to determine the appropriate subsequent encounter code.

Treatment Options

Treatment focuses on supporting healing and may include:

• Prolonged or adjusted immobilization (e.g., cast, splint) to stabilize the fracture
• Pain management with over-the-counter or prescription medications
• Physical therapy to maintain mobility and strength during healing
• Monitoring with repeat imaging to assess progress
• Addressing underlying factors (e.g., nutritional deficiencies, smoking cessation) that may impede healing
• Surgical intervention (rare) if delayed healing persists or complications arise

Prognosis and Follow-Up

Most torus fractures with delayed healing eventually heal with appropriate management, though the timeline may be extended. Prognosis depends on the severity of the fracture, adherence to treatment, and any contributing health factors. Regular follow-up appointments are necessary to monitor healing, adjust treatment, and ensure functional recovery. Full return to normal activities is typically expected, but recovery time may be longer than for uncomplicated fractures.

Complications

• Persistent pain or discomfort
• Limited range of motion or stiffness in the wrist or forearm
• Nonunion (failure of the fracture to heal)
• Malunion (healing in an abnormal position)
• Associated soft tissue injury or nerve compression
• Increased risk of future fractures in the same area

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, playground play)
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Avoid smoking and limit alcohol, as these can impair bone healing
• Engage in weight-bearing exercises to support bone density (as appropriate)
• Follow post-injury care instructions closely to promote optimal healing

When to Seek Professional Help

Seek medical attention if:

• Pain worsens or does not improve with treatment
• Swelling, bruising, or deformity increases
• Numbness, tingling, or weakness develops in the hand or fingers
• The cast or splint becomes loose or damaged
• Healing progress stalls or symptoms recur after initial improvement

Tips for Medical Coders

This code (S52.621G) is used for a subsequent encounter for a torus fracture of the lower end of the right ulna with delayed healing. Documentation should specify the fracture type, location (right ulna), and the reason for the encounter (delayed healing). Ensure the encounter is classified as "subsequent" and that the fracture is confirmed to be healing slowly. Avoid using this code for initial encounters or fractures without delayed healing. Verify that laterality (right) and the specific fracture type (torus) are clearly documented to support accurate coding.
