Management of scaphoid nonunion

Area of Science:

• Orthopedic Surgery
• Musculoskeletal System Research

Background:

• Scaphoid nonunion is a significant complication of scaphoid fractures.
• Displacement and instability are primary risk factors, but delayed diagnosis and inadequate treatment also contribute.
• Untreated nonunion can progress to scaphoid nonunion advanced collapse (SNAC) wrist, a form of degenerative wrist arthritis.

Purpose of the Study:

• To review the risk factors, diagnosis, and treatment options for scaphoid nonunion.
• To discuss the natural history and potential impact of surgical intervention on scaphoid nonunion outcomes.

Main Methods:

• Review of existing literature on scaphoid nonunion.
• Analysis of diagnostic modalities including radiography, CT, and MRI.
• Evaluation of various surgical and non-surgical treatment strategies.

Main Results:

• Key risk factors include fracture displacement, delayed diagnosis, and compromised blood supply.
• Radiographs are standard for diagnosis, with CT and MRI aiding in deformity and vascular assessment.
• Treatment spectrum includes percutaneous fixation, open reduction with internal fixation (with or without bone grafting), and salvage procedures.

Conclusions:

• Effective management of scaphoid nonunion requires accurate diagnosis and appropriate treatment selection.
• The natural history of scaphoid nonunion remains debated, particularly regarding the impact of surgery on union rates and long-term outcomes.
• Treatment choice depends on fracture characteristics, patient factors, and desired outcomes, ranging from conservative measures to complex reconstructive surgeries.
