Cup Positioning | Dr. Juan Suarez | AHF 2024

Описание: Dr. Juan Suarez from Baptist Health South Florida shares his perspectives on Cup Positioning at AHF 2024.

Dr. Suarez was attracted to the anterior approach because it allowed using fluoroscopy during surgery to ensure accurate implant positioning, avoiding surprises in recovery

Accurate cup positioning is important, as 20% of hip revision surgeries are done for instability issues according to AJR data

He helped develop the "Cuptomizee" technology to determine pelvic tilt and predict cup position in sitting and standing

Cuptomize uses standing/supine AP and lateral x-rays to calculate pelvic tilt and desired cup angles

Intraoperatively, it overlays the preop plan on live fluoro to guide optimal cup positioning for that patient's pelvic tilt

The goal is typically 20-30° anteversion when standing, and at least 20° anteversion when sitting

The anterior approach may mitigate instability risk in patients with altered spinopelvic dynamics based on recent studies

There are sometimes tradeoffs in cup positioning vs. bony coverage that require judgement calls

Pelvic tilt can change after correcting contractures, so assumptions pre/post-op may differ

Both anteversion and inclination angles impact risk of anterior vs posterior instability
