Summary
Rigid fixation without bone grafting effectively treats fibrous scaphoid nonunion. Factors like older age and delayed surgery (>1 year) may impact patient-reported outcomes.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Trauma Surgery
Background:
- Scaphoid nonunion often requires bone grafting.
- Fibrous nonunion may be amenable to fixation without grafting.
Purpose of the Study:
- Evaluate outcomes of compression screw fixation for scaphoid fibrous nonunion without bone graft.
- Assess the efficacy of rigid fixation in established fibrous nonunions.
Main Methods:
- Retrospective case series of 14 patients with scaphoid fibrous nonunion treated with compression screw fixation.
- Defined fibrous nonunion by tenderness, radiographic evidence, and duration (>6 months).
- Assessed outcomes via range of motion, DASH scores, grip strength, and radiographs.
Main Results:
- 12 of 14 patients achieved healing with an average time of 4.4 months.
- Postoperative DASH scores averaged 10.2, with mean pain scores of 1.4.
- Older age and injury-to-surgery interval >1 year correlated with poorer self-assessed outcomes.
Conclusions:
- Compression screw fixation without bone grafting is a viable option for fibrous scaphoid nonunion.
- Patient age and delayed surgical intervention negatively influence functional outcomes.

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...
