ANTERIOR LUMBAR INTERBODY FUSION WITH HARTSHILL HORSESHOE CAGE

Objectives: The purpose of this study is to assess the role of the Hartshill horseshoe cage for lumbar and lumbosacral interbody fusion through anterior Robinson–Smith construct. Materials: About 25 adults (11 males and 14 females), aged 29 to 56 years were the subject materials. Disease entities were post-traumatic internal derangement, isthmic and degenerative spondylolisthesis and lumbar scoliosis (DLS). The fusion levels were L4−5 in 21 and L5–S1 in four patients, braced postoperatively for 2–3 months. Results: Fusion took place at least five months on average (4–7 months). No complications were encountered. In one DLS patient who had multi-segment posterior instrument-aided stabilization (T11–S1), the lowest pedicle screw became loosened gradually, but cage was maintained intact without loosening. Conclusion: Hartshill horseshoe cage offered a conducive biomechanical environment for anterior interbody fusion.
