Clinical Scorecard: Analysis of the Incidence and Contributing Factors for Fixation Failure in Adult Femoral Neck Fractures: A Single-Center Study

At a Glance

Key Highlights

• Fixation failure occurred in 24.0%, avascular necrosis (AVN) in 14.3%, and nonunion in 9.7% of patients.
• Displaced fractures (Garden III/IV), poor reduction quality, and excessive alcohol consumption independently increased risk of fixation failure and AVN.
• Earlier surgery (within 3 days) and use of cannulated screw fixation were associated with reduced odds of nonunion.

Guideline-Based Recommendations

Diagnosis

• Assess fracture displacement using Garden classification to identify high-risk fractures (III/IV).
• Evaluate reduction quality postoperatively to predict fixation outcomes.

Management

• Prioritize early surgical intervention, ideally within 1 day, to reduce nonunion risk.
• Use cannulated screw fixation where appropriate to lower nonunion incidence.
• Address modifiable risk factors such as excessive alcohol consumption pre- and postoperatively.

Monitoring & Follow-up

• Monitor patients closely for signs of fixation failure, AVN, and nonunion during follow-up.
• Regular imaging to assess fracture healing and implant position.

Risks

• Displaced fracture patterns and poor reduction quality increase risk of fixation failure and AVN.
• Excessive alcohol consumption significantly raises risk of fixation failure and AVN.
• Delayed surgery beyond 3 days increases nonunion risk.

Patient & Prescribing Data

217 adult patients undergoing internal fixation for femoral neck fractures

Cannulated screw fixation and earlier surgery are associated with better healing outcomes; modifiable lifestyle factors like alcohol consumption impact complication rates.

Clinical Best Practices

• Optimize fracture reduction quality intraoperatively to minimize fixation failure and AVN.
• Schedule surgery as early as possible, preferably within 24 hours of injury.
• Select fixation method carefully, favoring cannulated screws when suitable.
• Counsel patients on reducing alcohol consumption to improve healing outcomes.
