Endoscopy-assisted Periacetabular Osteotomy: A Preliminary Cadaveric Study

Periacetabular osteotomy has been recommended for reconstructing symptomatic dysplastic hips in adolescents and young adults, but requires substantial incisions and exposure. To minimize large incisions, we asked whether periacetabular osteotomy could be performed with a mini-incision under direct e...

Description
Summary:Periacetabular osteotomy has been recommended for reconstructing symptomatic dysplastic hips in adolescents and young adults, but requires substantial incisions and exposure. To minimize large incisions, we asked whether periacetabular osteotomy could be performed with a mini-incision under direct endoscopic control. We used five fresh-frozen cadaver pelves and developed curved guides and osteotomes for the osteotomy. We were able to perform a periacetabular osteotomy under endoscopic and image intensifier control and to fix the osteotomy with two cannulated screws. We identified no damage to vital structures or intraarticular fracture in any of the five cadavers we subsequently dissected. We believe periacetabular osteotomy may be performed with a mini-incision under direct endoscopic control. Our preliminary observations suggest the approach might be explored in limited prospective clinical trials by experienced individuals.
