Femoracetabular impingement treated with surgical hip dislocation: Short-term results

Area of Science:

• Orthopaedic Surgery
• Hip Arthroscopy
• Musculoskeletal Disorders

Background:

• Femoroacetabular impingement (FAI) is a hip condition often treated surgically.
• Existing literature on surgical hip dislocation for FAI predominantly features data from Europe and North America.
• Limited data exists on FAI treatment outcomes in South American populations.

Purpose of the Study:

• To describe the short-term clinical and radiological outcomes of the LQC technique for FAI treatment.
• To evaluate the efficacy and safety of the LQC technique in a Colombian patient cohort.
• To contribute regional data to the global understanding of FAI surgical management.

Main Methods:

• Retrospective analysis of 42 patients with FAI treated with the LQC technique between 2006 and 2018.
• All surgeries were performed by a single orthopaedic surgeon.
• Clinical outcomes assessed using Merle d'Aubigné scores; radiological outcomes using Tönnis scores.

Main Results:

• The study included 42 patients (15 female, 25 male; mean age 36.3 years).
• Postoperative Merle d'Aubigné scores showed significant improvement, with 35 of 42 cases rated good to excellent (p<0.05).
• Low complication rates observed, including one case of heterotopic ossification and three of trochanteric nonunion.

Conclusions:

• The LQC technique offers satisfactory short-term results for treating FAI.
• The procedure demonstrated a low complication rate in this Colombian cohort.
• This study represents the first report of surgical hip dislocation outcomes in this region.
