[Deformities of the hip joint as cause of groin pain: diagnostics and therapy].

Chronic groin pain in adults is often attributable to hip joint pathologies. This article analyzes important orthopedic differential diagnoses, including hip dysplasia, acetabular version abnormalities, femoral torsion anomalies, femoroacetabular impingement (FAI), femoral head necrosis, and osteoarthritis. The pathophysiology of these conditions frequently lead to disrupted joint mechanics, leading to premature degeneration and arthritis. The diagnostics include patient history, clinical examination and imaging modalities such as X‑ray, magnetic resonance imaging (MRI) or computed tomography (CT). Treatment options include conservative measures (e.g., physiotherapy, pain management) or surgical interventions, e.g., arthroscopy for FAI, periacetabular osteotomy (PAO) for dysplasia and total hip arthroplasty (THA) for advanced osteoarthritis. The choice of treatment depends on factors, such as age, disease severity and lifestyle. Preventive measures, early detection of pre-arthritic deformities and regular monitoring of patients at-risk can slow degenerative progression; however, in cases of advanced osteoarthritis THA often remains the last option for preserving mobility and quality of life.
