Core Tip

Core Tip: Total hip arthroplasty in developmental dysplasia of the hip carries the risk of transacetabular screw protrusion and neurologic injury. In case of sciatic nerve palsy due to intrapelvic screw penetration, an extra-acetabular approach with exploration of the sciatic nerve and resection of the prominent screw tip can allow immediate pain relief without compromising cup stability and avoiding joint dislocation, liner exchange and component revision.
