Loder classification: **Stable** (able to walk, even with aids) vs **Unstable** (non‑ambulatory) — strongest predictor of AVN. Typical patient: obese adolescent (boys > girls), endocrine risk (hypothyroid, GH therapy). Imaging: AP pelvis and frog‑leg lateral; Klein’s line, Trethowan sign; quantify slip by **Southwick angle**. Treatment: **In‑situ single‑screw fixation** for stable slips; **urgent gentle reduction and pinning** for unstable slips in theater with minimal manipulation. Consider **contralateral prophylactic pinning** for high‑risk patients (younger, open triradiate, endocrine).
