Insights
Snapping hip syndrome can persist after surgery in some patients. A smaller femoral neck angle may be associated with this condition, potentially impacting surgical outcomes.
Area of Science:
- Orthopedic Surgery
- Biomechanical Analysis
Background:
- Snapping hip syndrome is a common condition characterized by an audible or palpable snapping sensation during hip movement.
- Surgical interventions are performed to address persistent or painful snapping hip symptoms.
Purpose of the Study:
- To evaluate the long-term outcomes of surgical treatment for snapping hip syndrome.
- To investigate potential biomechanical factors, such as femoral neck angle, associated with persistent snapping hip post-operatively.
Main Methods:
- A retrospective follow-up study of 31 snapping hips in 24 patients who underwent surgery.
- Assessment of symptom persistence (snapping and pain) at an average of 4 years post-operation.
- Comparison of femoral neck angles between operated patients and a control group.
Main Results:
- Snapping persisted in 9 out of 31 hips (29%) at follow-up.
- Three of these cases (10% of total) also experienced associated pain.
- Patients with persistent snapping had a smaller average femoral neck angle (128 degrees) compared to controls (134 degrees).
Conclusions:
- Surgical treatment for snapping hip syndrome does not guarantee complete resolution of symptoms in all cases.
- A reduced femoral neck angle may be a predisposing factor or associated finding in patients experiencing persistent snapping hip post-surgery.
Abstract:
Thirty-one snapping hips in 24 patients were followed for 4 (1-11) years after operation. At follow-up, snapping persisted in nine hips, in three cases accompanied by pain. The femoral neck angle was less in the patients (128 degrees) than in a control group (134 degrees).
