Summary
Cubitus varus deformities after elbow fractures require corrective osteotomies. Unstable internal fixation often leads to poor results, necessitating improved fixation techniques for better outcomes.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Traumatology
Background:
- Cubitus varus deformities can occur after elbow fractures.
- Corrective lateral-wedge osteotomies are used to address these deformities.
- Previous fixation methods have shown variable success rates.
Purpose of the Study:
- To evaluate the outcomes of corrective lateral-wedge osteotomies for post-traumatic cubitus varus.
- To identify factors contributing to poor surgical results.
- To recommend improved internal fixation strategies.
Main Methods:
- Retrospective review of 23 patients (26 osteotomies) with cubitus varus deformities.
- Analysis of fixation methods including Steinmann pins, screws with wire, and small plates.
- Assessment of intraoperative correction and postoperative stability.
Main Results:
- 16 patients had good results, while 10 had poor results.
- Poor outcomes were associated with inadequate intraoperative correction or unstable internal fixation.
- Loss of fixation and distal fragment slippage occurred in both good and poor outcome groups, leading to hyperextension.
Conclusions:
- Unstable internal fixation is a significant cause of poor outcomes in corrective osteotomies for cubitus varus.
- A combination of a two-hole lateral plate and a percutaneous medial pin is recommended for enhanced stability.
