Insights
Emergent surgical fixation for Pipkin type-I fractures improves outcomes. Early intervention reduces complications and avascular necrosis, leading to better patient results compared to delayed fixation.
Area of Science:
- Orthopedic Surgery
- Trauma Care
- Femoral Head Fractures
Background:
- Pipkin type-I fractures involve the femoral head.
- Management of large fragments requires careful consideration of timing.
Purpose of the Study:
- To evaluate the impact of surgical fixation timing on Pipkin type-I fractures.
- To compare outcomes between emergent and secondary fixation strategies.
Main Methods:
- Prospective observation of 36 Pipkin type-I fracture patients.
- Randomization into emergent surgical fixation versus secondary fixation after closed reduction.
- Analysis of baseline characteristics, operative details, hospital stay, and long-term complications.
Main Results:
- No significant differences in baseline characteristics, operating time, or blood loss between groups.
- Emergent fixation group experienced shorter hospital stays.
- Higher rates of complications and avascular necrosis observed in the secondary fixation group.
Conclusions:
- Emergent surgical reduction and fixation of Pipkin type-I fractures are associated with better outcomes.
- Delayed fixation increases the risk of avascular necrosis and poor results.
- Early intervention is recommended for optimal treatment of these injuries.
Abstract:
The purpose of this study was to assess the effect of timing of large fragment fixation in patients with Pipkin type-I fractures. Patients with Pipkin type-I fractures from the authors' trauma center were prospectively observed between July 2007 and July 2010. Fragments that constituted more than one-fourth of the femoral head were included. Thirty-six patients were equally randomized to undergo emergent surgical reduction and fixation or secondary operative fixation after emergent closed reduction. No significant differences existed between the 2 groups with regard to the baseline characteristics, operating time, and blood loss (P>.05). However, the emergent surgical reduction and fixation group had a shorter hospital stay (P<.05). The results after more than 2-year follow-up showed that the complication and avascular necrosis rates were higher in the secondary operative fixation after emergent closed reduction group compared with the emergent surgical reduction and fixation group (P<.05). It was difficult to achieve an anatomically reduced femoral head when the fragments constituted more than one-fourth of the femoral head. Patients who underwent secondary operative fixation after emergent closed reduction had a high avascular necrosis rate and a relatively poor outcome. Emergent surgical reduction and fixation should be performed shortly after injury to enhance the treatment outcome.
