S52.225E Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type I or II with routine healing

Summary

A nondisplaced transverse fracture of the shaft of the left ulna is a straight-line break across the long, central portion of the ulna bone (one of the two forearm bones) where the bone fragments remain in their normal anatomical alignment. The fracture runs horizontally through the bone shaft, and the lack of displacement means the bone pieces are not shifted out of position. This is a subsequent encounter for an open fracture type I or II, indicating the skin was breached but the wound is small and clean, and healing is progressing as expected without complications.

Causes

Direct trauma to the forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions. Indirect forces transmitted through the wrist or elbow, potentially causing a break in the ulna shaft.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Previous fractures or bone abnormalities that may predispose to injury.
• Advanced age, which can reduce bone strength.

Symptoms

• Pain and tenderness localized to the forearm.
• Swelling and bruising around the injured area.
• Difficulty moving the arm, wrist, or hand due to pain or instability.
• Possible visible deformity if the fracture is displaced (though less common in nondisplaced cases).

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging studies, such as X-rays, to confirm the fracture type, location, and displacement. Evaluation of the wound for open fracture classification (type I or II) and assessment of healing progress.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture and promote healing.
• Pain management with medications as needed.
• Wound care for open fractures to prevent infection.
• Physical therapy to restore strength and mobility once healing allows.
• Follow-up imaging to monitor bone union and healing status.

Prognosis and Follow-Up

With proper treatment and routine healing, the prognosis is generally favorable. Follow-up appointments are necessary to assess healing progress, ensure the fracture is stable, and guide rehabilitation. Most patients regain full function with time, though recovery may vary based on individual factors.

Complications

• Infection (rare, but possible with open fractures).
• Delayed union or nonunion of the fracture.
• Stiffness or reduced range of motion in the forearm or wrist.
• Nerve or blood vessel injury (uncommon but serious).

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, work).
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Follow post-injury guidelines to support healing and prevent re-injury.

When to Seek Professional Help

• Increased pain, swelling, or redness around the injury site.
• Signs of infection (e.g., fever, pus, warmth).
• Numbness, tingling, or changes in skin color (possible nerve or vascular involvement).
• Difficulty moving the arm or wrist despite treatment.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of left ulna), encounter type (subsequent), and open fracture classification (type I or II) with routine healing. Include details on wound status, healing progress, and any treatments provided to support code accuracy. Ensure documentation reflects the absence of complications or delayed healing.
