Greater Trochanteric Pain after Total Hip Arthroplasty: The Incidence, Clinical Outcome and Associated Factors
Bibliographic record
Abstract
We evaluated any residual pain around the hip joint 11 to 23 months post-surgery in 172 consecutive patients who underwent total hip arthroplasty (THA) for primary or secondary osteoarthritis during 2002 at Sundsvall Hospital, Sweden. Patients with suspected greater trochanteric pain (GTP) were matched with controls from the same cohort. The two groups were assessed with the Western Ontario and McMaster Universities Arthrosis Index (WOMAC) and were examined for localised tenderness over the trochanteric area by algometer. The pre- and postoperative radiographs including femoral offset were evaluated. We found that 21 patients (12%) had GTP with a male to female ratio of 1:6. The WOMAC index revealed a reduction in the clinical outcome in this group. An associated factor of significance was postoperative uncorrected lengthening of the operated limb equal to or more than one centimetre. We found no correlation between the prevalence of GTP and body weight or length, femoral offset or size of the prosthetic components used.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
