Congenital Tibial Deficiency and Reconstruction Strategies

Congenital tibial deficiency, often termed tibial hemimelia, is a rare embryological disorder characterised by partial or complete absence of the tibial shaft and its anlage. Incidence is estimated at one per million live births, with presentations ranging from mild hypoplasia to total tibial agenesis. Clinical features include leg‐length discrepancy, deformity of the knee and ankle joints, and variable preservation of the extensor mechanism. Historically, amputation with prosthetic fitting has been regarded as the primary treatment owing to predictable functional outcomes. However, advances in limb reconstruction—including classification‐guided decision‐making, centralisation of the fibula, staged soft‐tissue release, and modern distraction osteogenesis—have expanded salvage options. Multidisciplinary care integrating paediatric orthopaedics, rehabilitation medicine and prosthetic specialists is critical for individualised planning. Recent approaches focus on preserving weight‐bearing limbs, optimising joint congruity and minimising growth plate disturbance. Surgical algorithms now consider the presence of a patella, quadriceps integrity and knee joint stability to guide reconstructive versus ablative pathways. Despite technical complexity, reconstruction can offer improved biomechanical function and patient satisfaction in selected cases. Ongoing research into genetic underpinnings and tissue engineering may further refine future strategies.
