Intertrochanteric Imhäuser osteotomy combined with osteochondroplasty in treatment of moderate-severe stable slipped capital femoral epiphysis: a case series study
Bibliographic record
Abstract
The aim of the study is to assess the safety and efficacy of Imhäuser osteotomy combined with osteochondroplasty in the treatment of moderate-severe stable slipped capital femoral epiphysis (SCFE) on short-term basis. Nineteen patients (20 hips) with moderate-severe stable SCFE were surgically treated by Imhäuser osteotomy combined with osteochondroplasty and followed up for 3-4 years. The cases aged between 12 and 18 years at the time of surgery and complained of a variety of symptoms and signs that included pain, limping, limited range of motion (ROM), and/or abductor weakness. The outcomes were assessed using clinical and radiological parameters as well as functional outcome measures: "Harris hip score" (HHS) and "The Western Ontario and McMaster Universities Osteoarthritis Index" (WOMAC). There were statistically significant improvements in flexion, internal rotation, and abduction ROM. HHS and WOMAC improved significantly with final follow-up scores at 86.76 and 6.4%, respectively. The radiological parameters showed significant improvement regarding Southwick angle (mean 12.8°), alpha angle of Nötzli (mean 29.85°), Hilgenreiner epiphyseal angle (mean 37.65°), neck shaft angle (mean 140.63°), and acetabulo-trochanteric distance (median14.1 mm) at the end of follow-up period. Imhäuser osteotomy combined with osteochondroplasty is a good option in moderate-severe stable SCFE treatment.

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.
