Description and mid-term results of the ‘over the top’ technique for the treatment of the pincer deformity in femoroacetabular impingement
Bibliographic record
Abstract
Pincer impingement is often treated by surgical labral separation from the acetabular rim and rim reduction. A more recent technique the so-called 'over the top' involves reduction of the bony acetabular rim without separation of the labrum. Our purpose is to report mid-term results of the 'over the top' technique. Between January 2006 and January 2013 a consecutive series of patients with femoroacetabular impingement (FAI) diagnosis, treated with the 'over the top' technique were included, using the lateral approach. The Western Ontario and MacMaster (WOMAC) scores were evaluated. Fifty patients (20 males and 30 females) from the Hip and Knee Joint Reconstructive and hip arthroscopy division were included. The average age was 30.5 years old and the average follow-up was 48 months (range 70-90). Preoperative WOMAC average was 42. Post-operative WOMAC was 81.3 (P = 0.01). One patient required an arthroscopic revision due to adherences, but had a full recovery after the revision surgery. The 'over the top' technique is an excellent choice for the treatment of the pincer deformity in the FAI avoiding the injury of the chondrolabral union.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
