1. Patient Set Up
1. Patient Set Up • Adequate traction requires approximately 10 mm of distraction across the joint. • Careful attention to padding is critical.
2. Access – Portals 1. Anterior 2. Anterolateral 3. Posterolateral Greatest Risk →→ Anterior Portal – Avg. 3 mm from a branch of the lateral femoral cutaneous nerve Primal Pictures Limited
2. Access: Expanded Portal Placement • Palpate and Outline: – Greater Trochanter – Anterior Superior Iliac Spine (ASIS) • Portal Placement – Anterolateral Portal (AL) • 1 cm superior and anterior to GT – Posterolateral (PL) • 1 cm superior and posterior to GT – Anterior Portal (AP) • In line with AL portal • 1 cm lateral to ASIS – Mid-Anterior Portal (MAP) – Proximal Mid-Anterior Portal (PMAP)
Portal Safety 1. The Mid-Anterior and Anterior portals pass in close proximity to a small terminal branch of the ascending LCFA 2. Greatest risk still comes from the proximity of the anterior portal to the LFCN – A slightly more lateral location may provide some protective benefit
Safe Zone Robertson et al, Arthroscopy 2008. • The findings from this study seem to support the concept of a relative neurovascular safe zone for arthroscopic access to the hip joint within the outlined parameters.
2. Access / Visualization
2. Access / Visualization
2. Access / Visualization Transition zone injury Contra-Coup injury
3. Capsule Cut
3. Capsule Cut – IA Evaluation Cam Injury • Cam delamination • Loss of normal attachment of labrum to transition zone. Rim Injury • Capsular sided injury to the labrum / capsule against the rim lesion
4. Rim Preparation Rim Exposure Rim Decompression • Severe rim inflammation around the rim lesion • Outline the rim lesion prior to decompression
4. Rim Preparation
3. Rim Resection
