When is surgical intervention indicated for a subacute healing distal radial styloid fracture (fx) in a 13-year-old female?

From the Guidelines

Surgical intervention is indicated for a subacute healing distal radial styloid fracture in a 13-year-old female when there is postreduction radial shortening >3 mm, dorsal tilt >10°, or intra-articular displacement, as suggested by the treatment guidelines 1. When considering treatment options for a subacute healing distal radial styloid fracture in a pediatric patient, it's essential to weigh the benefits of surgical intervention against the potential risks and complications.

• The primary goal of treatment is to achieve and maintain acceptable fracture alignment, promote healing, and prevent long-term functional impairment or growth disturbance.
• Conservative management with cast immobilization is often the first-line treatment for pediatric distal radius fractures, including styloid fractures, due to the excellent remodeling potential in children 1.
• However, surgical intervention becomes necessary when there is significant displacement, angulation, or instability that cannot be managed conservatively.
• The specific indications for surgery in this case, as outlined in the treatment guidelines, include postreduction radial shortening >3 mm, dorsal tilt >10°, or intra-articular displacement 1.
• The decision to proceed with surgery should also consider the patient's skeletal maturity, as a 13-year-old female is likely approaching skeletal maturity, which means less remodeling potential compared to younger children.
• Surgical options may include percutaneous pinning, open reduction internal fixation with K-wires or screws, or rarely plate fixation, depending on the fracture pattern and stability.
• Post-surgical management typically involves 4-6 weeks of immobilization followed by progressive range of motion exercises and strengthening under the guidance of a physical therapist to restore function.

From the Research

Subacute Healing Distal Radial Styloid Fracture Treatment

• The treatment of subacute healing distal radial styloid fractures in a 13-year-old female can be surgical, depending on the severity and displacement of the fracture 2, 3.
• Surgical options include closed reduction, percutaneous pinning, external fixation, and open reduction and internal fixation 2.
• A minimally invasive intramedullary fixation technique can be used for distal radial fractures that do not involve the articular surface, which is a safe and effective technique that can provide excellent results 2.
• Open reduction and internal fixation with a volar plate can provide better functional results in the early postoperative period, especially for patients requiring a faster return to function after the injury 3.

Indications for Surgery

• Surgery may be indicated for unstable, displaced, or comminuted fractures, as well as for fractures with associated injuries such as carpal fractures or dislocations 4.
• The decision to operate on a radial styloid fracture should be based on the individual patient's condition, the severity of the fracture, and the presence of any associated injuries 4.
• For unstable distal radial fractures, minimally invasive percutaneous internal fixation can be an effective treatment option, with advantages including smaller wound, incisional concealment, and quicker recovery of wrist joint 5.

Considerations for Treatment

• The treatment of radial styloid fractures should take into account the complexity of the surrounding anatomy and the potential for complications related to surgical approach, treatments, and symptomatic hardware 4.
• The outcome of treatment is related to the precision of the reconstruction and the magnitude of the injury, with better results associated with lower-energy patterns 4.
• Ulnar styloid fracture or non-union does not affect the outcome of an adequately fixed distal end radius fracture, and operative treatment of non-united fracture of the ulnar styloid should be approached with caution 6.
