Case in brief
A 23-year-old woman with Morquio syndrome type B had disabling bilateral hip pain associated with osteoarthritis and hip dysplasia. Planning for staged bilateral robot-assisted total hip arthroplasty showed markedly asymmetric femoral anteversion (48° on the left and 38° on the right) and a need for a 40-mm acetabular component not available in the robotic implant catalog. A hybrid approach used robotic planning and haptic-guided reaming with an off-catalog component. At 1 year, she was asymptomatic, with Harris Hip Scores of 95 and 96.
What made this case unusual
The dysplastic anatomy required a 40-mm acetabular component outside the robotic implant catalog, so robotic planning and haptic guidance were combined with off-catalog component implantation while managing asymmetric femoral anteversion.
Diagnostic / clinical pearl
In this case, robotic planning and haptic-guided reaming could be adapted to small dysplastic acetabula despite implant-size constraints.
