Overview
Multiple Epiphyseal Dysplasia-Miniepiphyses Syndrome is a rare genetic skeletal dysplasia characterized by strikingly small secondary ossification centers (mini-epiphyses), particularly affecting the proximal femoral heads. Clinical features include short stature, increased lumbar lordosis, genua vara (bowlegs), generalized joint laxity, and premature osteoarthritis. Diagnosis relies on radiographic identification of abnormal epiphyseal ossification patterns and genetic testing to confirm pathogenic variants [6][19].
Burden
Progressively debilitating joint pain, restricted mobility, and early-onset osteoarthritis (often by adolescence/adulthood) [6][2].
High surgical burden: 50% of patients require orthopedic procedures by adulthood (e.g., hip replacements) [2][8].
Chronic disability impacts education, employment, and quality of life, with 30%-40% developing scoliosis or muscular atrophy in later stages [2][8][6].
Therapies
Symptomatic management: NSAIDs for pain, physical therapy to maintain joint mobility, and low-impact exercise regimens [8][3][5].
Surgical interventions: Osteotomies for severe deformities, excision of symptomatic double-layered patellae, and joint replacement surgeries for advanced osteoarthritis [3][8][11].
Supportive care: Vitamin C supplementation (for COL9-mutated cases) and weight management to reduce joint stress [8].
