Summary
This study compared Kirschner wire fixation with Keller arthroplasty. Distractor use showed a weak correlation with improved range of motion and patient satisfaction, possibly due to temporary joint space increase and subsequent fibrosis.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
Background:
- Hallux rigidus is a common degenerative condition affecting the first metatarsophalangeal joint.
- Surgical options include joint-preserving procedures like Kirschner wire fixation and joint-sacrificing procedures such as Keller arthroplasty.
Purpose of the Study:
- To compare the outcomes of single or crossed intramedullary Kirschner wire fixation versus straight Keller arthroplasty.
- To investigate the role of distractors in influencing range of motion and patient satisfaction.
Main Methods:
- Retrospective study design.
- Comparison of two surgical techniques: intramedullary Kirschner wire fixation and Keller arthroplasty.
- Analysis of patient data including range of motion and satisfaction scores.
Main Results:
- A weak positive correlation was observed between the use of distractors and increased range of motion.
- Distractor use also weakly correlated with higher overall patient satisfaction.
- The observed benefits are hypothesized to stem from a temporary increase in joint space, promoting early postoperative fibrosis and improved functional outcomes.
Conclusions:
- Intramedullary Kirschner wire fixation and Keller arthroplasty are viable surgical options for hallux rigidus.
- The use of distractors may offer a modest benefit in improving range of motion and patient satisfaction.
- Further prospective studies are warranted to confirm these findings and elucidate the underlying mechanisms.
