Radiomics promises quantitative biomarkers extracted from routine hip imaging to support diagnosis, prognosis, and surgical planning, but current evidence is fragmented across pathologies, modalities, and computational pipelines. We conducted a scoping review following PRISMA-ScR and the Population–Concept–Context framework, including peer-reviewed original studies on adults (≥18 years) that applied radiomics or deep-radiomics to hip imaging (X-ray, CT, MRI, DEXA) with clinically relevant outcomes. PubMed (MEDLINE), Embase and Scopus (Elsevier) were searched from 1 January 2021 to 30 August 2025 and complemented by snowballing; screening and data charting were performed in duplicate. Given heterogeneity, findings were synthesized narratively by a priori clusters. In fragility/osteoporosis, opportunistic CT and radiograph-based models frequently achieved AUCs around 0.90–0.96, while DXA-radiomics added information beyond bone mineral density/FRAX and trabecular MRI provided complementary microarchitectural signals. For osteonecrosis of the femoral head, multisequence MRI enabled early diagnosis with AUCs > 0.94; radiomics differentiated transient bone marrow edema with AUCs~0.92–0.94 and predicted collapse using radiographs or MRI with AUCs~0.85–0.90, including automated pipelines with external validation around 0.85. In femoroacetabular impingement, 3D Dixon-MRI studies reported very high performance (~0.97–1.00) with preliminary multicenter generalizability and added value from periarticular soft-tissue features. In total hip arthroplasty, radiomics anticipated press-fit cup stability from preoperative radiographs (AUC~0.82) and predicted 6-month functional recovery using clinico-radiomic CT models (AUC~0.95). Across clusters, methodological robustness was variable (sample sizes, harmonization, leakage control, external/temporal validation, calibration, clinical utility). Radiomics for adult hip disorders shows tangible translational promise in opportunistic screening, complex differential diagnosis, and perioperative decision support, but broader clinical adoption will require multicenter datasets, IBSI-aligned standardization, transparent reporting of calibration and decision-curve analyses, and prospective validation.

Background: Femoral neck fractures in the elderly often necessitate hemiarthroplasty, but the optimal surgical approach remains a highly debated topic. The postero-lateral and direct lateral approaches are commonly employed, each with benefits and drawbacks. Despite their widespread use, robust, long-term comparative studies on definitive outcomes, including pain, functional recovery, and complication rates, are notably lacking. This systematic review and meta-analysis aim to address this critical gap by meticulously comparing these approaches with long-term follow-up. Methods: A systematic literature search was performed, including only comparative studies with a minimum 1-year follow-up. A meta-analysis was performed for the primary outcome measures: operative time, dislocations, infections, perioperative fractures and reoperations. Secondary outcomes included a qualitative synthesis of patient-reported outcomes (quality of life, pain, and satisfaction). Methodological quality was assessed using RoB 2.0 for randomized controlled trials and MINORS criteria for cohort studies. Results: Our meta-analysis provides robust quantitative evidence. The direct lateral approach is associated with a significantly lower risk of post-operative dislocations (I² = 58%; OR = 2.86, 95% CI: 2.53 to 3.22; p < 0.00001) and a significantly lower rate of reoperation (I² = 0%; OR = 1.25, 95% CI: 1.12 to 1.40; p = 0.0001) compared to postero-lateral approach. Operative time, infection, and perioperative fracture rates were found to be statistically comparable. However, patient-reported outcomes yielded inconsistent results across studies, often becoming non-significant after adjusting for confounders. Conclusions: This meta-analysis shows that the direct lateral approach is associated with lower rates of dislocation and reoperation compared with the postero-lateral approach, while patient-reported outcomes remain variable across studies. Further high-quality comparative trials are needed to confirm these associations and guide surgical decision-making.
