Unlocking Healing: A Comprehensive Guide to Scaphoid Fracture Surgery

 

A scaphoid fracture is a type of fracture considered to be of one of the eight small bones of the wrist, in the forearm side which joins the thumb. While many wrist fractures would heal with casting and immobilization, scaphoid bone fractures seem to attract some special consideration because of poor blood supply and the importance of this bone in wrist mechanics. Surgical treatment in nondisplaced or displaced nonunion of fractures of the scaphoid is the gold standard in order to restore function and prevent degenerative diseases in the long term, such as arthritis.






Understanding Scaphoid Fractures

The scaphoid lies across the two carpal rows, stabilizing and absorbing shock for the wrist. The common cause of fracture is a force transmitted through the scaphoid after a fall on an outstretched hand. Patients commonly report:

  • Palm-side wrist pain and tenderness just below the base of the thumb.

  • Swelling, bruising, and decreased grip strength.

  • Difficulty turning the wrist and performing everyday tasks.

Diagnosis often requires advanced imaging—X-rays may miss non-displaced fractures, so MRI or CT scans are employed for accurate assessment and to plan treatment.

Why Surgery Is Sometimes Necessary

Many scaphoid fractures heal well in a cast if they are non-displaced and diagnosed early. However, certain scenarios necessitate surgical repair:

  1. Displaced Fractures: When bone fragments have shifted, immobilization alone may not achieve proper alignment.

  2. Nonunion: If a fracture fails to unite after 12 weeks in a cast, surgical stabilization halts chronic pain and prevents arthritis.

  3. High-Risk Patients: Athletes or workers who require early return to function may opt for surgery to accelerate recovery.

Surgery optimizes outcomes by ensuring precise bone alignment, maintaining blood supply, and reducing prolonged immobilization.

Types of Scaphoid Fracture Surgery

Surgeons tailor the approach based on fracture pattern and patient needs. Common procedures include:

  • Percutaneous Screw Fixation
    A minimally invasive technique where a small incision is made, and a headless compression screw is inserted along the scaphoid axis to stabilize fragments. This method preserves soft tissue and allows early motion.

  • Open Reduction Internal Fixation (ORIF)
    For complex or severely displaced fractures, an open approach provides direct visualization. Surgeons realign the bone under direct view and secure it with screws or mini-plates, ensuring stable fixation.

  • Vascularized Bone Grafting
    In cases of nonunion or avascular necrosis (loss of blood supply), bone graft harvested, often from the distal radius or hip, is transferred with its blood supply intact to promote healing. This advanced technique addresses both mechanical and biological deficits.

The Surgical Procedure: Step by Step

  1. Anesthesia and Positioning
    Surgery is performed under regional or general anesthesia. The forearm is positioned on a hand table to grant optimal access to the scaphoid.

  2. Fracture Reduction
    Under fluoroscopic (live X-ray) guidance, displaced bone fragments are realigned to their anatomic position to restore wrist mechanics.

  3. Implant Placement
    A guidewire is first inserted, followed by drilling and placement of a headless compression screw or plate. If bone grafting is needed, the graft is secured at the nonunion site to bridge gaps and enhance healing.
    Incisions are closed, and the wrist is splinted or casted briefly to protect the repair. Many surgeons now favor early protected motion with a removable splint.

Postoperative Care and Rehabilitation

Recovery is a collaborative effort between patient, surgeon, and hand therapist:

  • Immobilization Phase (0–2 Weeks)
    A splint or light cast protects the incision and fixation. Elevation and icing minimize swelling.

  • Protected Motion (2–6 Weeks)
    Guided by a hand therapist, gentle wrist and thumb exercises begin to restore range of motion while maintaining protection for the fracture site.

  • Strengthening Phase (6–12 Weeks)
    As radiographic healing is confirmed, progressive strengthening and functional tasks are introduced, helping patients return to daily activities and sports.

  • Long-Term Follow-Up (3–6 Months)
    Periodic imaging ensures fracture consolidation. Most patients regain full wrist function by 3–4 months, with high-demand athletes sometimes returning sooner under supervision.

Potential Risks and How to Mitigate Them

All surgeries carry risks. Specific to scaphoid fracture repair, complications may include:

  • Nonunion or Delayed Union: Can occur despite surgery, particularly if blood supply is compromised.

  • Avascular Necrosis: Loss of blood flow to the proximal scaphoid fragment may necessitate further grafting procedures.

  • Hardware Irritation: Rarely, screws may protrude, requiring removal once healing is complete.

  • Wound Infection: Minimized by sterile technique and prophylactic antibiotics.

Choosing an experienced hand surgeon and adhering to rehabilitation protocols significantly lowers these risks.

Selecting the Right Scaphoid Fracture Surgeon

Expertise matters. Look for a board-certified hand and wrist specialist who:

  • Regularly performs scaphoid surgeries and employs both percutaneous and open techniques.

  • Maintains an integrated hand therapy program for seamless postoperative care.

  • Has access to advanced imaging (CT/MRI) to guide both diagnosis and surgical planning.

The Hand Surgery Specialists of Texas, for instance, offers minimally invasive scaphoid fixation techniques and bone grafting at multiple Houston locations, ensuring personalized and compassionate care.

Conclusion: Regaining Wrist Health and Function

Scaphoid fracture surgery is a specialized procedure designed to address fractures that won’t heal on their own or those requiring precise alignment. With advances in minimally invasive fixation, vascularized bone grafting, and tailored rehabilitation, patients can expect high rates of union and rapid return to function. If persistent wrist pain, instability, or imaging suggests a nonunion, consult a hand and wrist surgeon to explore the latest surgical treatments that will put you back in motion—stronger and pain-free.

Dorsal Wrist Ganglion Cysts: Causes, Symptoms, and Surgical Options

Image
  A lump on the back of your wrist can be alarming, especially if it seems to appear out of nowhere. Often, this bump is a dorsal wrist ganglion cyst —a common and usually harmless condition. While some cysts cause no issues and may even disappear on their own, others can lead to discomfort, restricted movement, or aesthetic concerns. Understanding the causes, symptoms, and treatment options can help you make informed decisions about your care.   ​What is a Dorsal Wrist Ganglion Cyst? A ganglion cyst is a fluid-filled sac that typically develops along joints or tendons. When it appears on the dorsal (back) side of the wrist , it's known as a dorsal wrist ganglion cyst. These cysts are filled with a thick, jelly-like fluid and can vary in size. They often become more prominent with repetitive wrist activity and may shrink when the wrist is at rest. ​Causes of Dorsal Wrist Ganglion Cysts The exact cause isn’t fully understood, but ganglion cysts are ...
