Summary
Percutaneous compression plates and dynamic hip screws show similar functional outcomes for AO 31A1 and 31A2 fractures. The compression plate technique resulted in less hemorrhage and shorter surgery times.
Area of Science:
- Orthopedic surgery
- Traumatology
Background:
- Femoral neck fractures, specifically AO 31A1 and 31A2 types, require effective surgical fixation.
- Percutaneous compression plating and dynamic hip screw fixation are common treatment modalities.
Purpose of the Study:
- To compare functional outcomes, hemorrhage, wound infection, complications, and implant stability between percutaneous compression plate and dynamic hip screw for AO 31A1 and 31A2 fractures.
Main Methods:
- A quasi-experimental, prospective, comparative study was conducted.
- 26 patients with AO 31A1 and 31A2 fractures were included, with 13 treated with each method.
- Statistical analysis included t-Student, Chi-square, and U Mann-Whitney tests (alpha=0.05).
Main Results:
- No significant differences were found in post-operative hospital stay, wound length, complications, or consolidation time.
- Surgical time and hemorrhage were significantly reduced in the percutaneous compression plate group (p < 0.05).
- No wound infections or complications were observed in either group.
Conclusions:
- Percutaneous compression plating provides comparable functional results to dynamic hip screw fixation for these fracture types.
- Percutaneous compression plating offers advantages including reduced surgical time and less intraoperative and postoperative hemorrhage.
