PURPOSE: To quantify arthroscopic accessibility of the talar dome with predefined ankle positions through anterior and posterior approaches. METHODS: Fourteen below-knee cadaver specimens underwent preoperative range of motion assessments. A 30° 2.7-mm arthroscopic camera was used to mark accessible areas at varying ankle positions. Accessible regions were quantified using a surface laser scanner and digital 3 × 3 grid. Statistical analyses were performed to detect differences in arthroscopic accessibility between different flexion angles and noninvasive distraction...

Femoral shaft fractures are common injuries with an incidence of 37.1 per 100,000 person-years in the United States. Retrograde femoral nailing is an increasingly used treatment strategy to manage these injuries, particularly in fractures below stemmed hip prostheses, in supracondylar or distal femur fractures, in fractures in pregnant or obese patients, and when concomitant ipsilateral acetabular/pelvic ring fractures are present. Retrograde fixation has been shown to be a viable option with union rates comparable to antegrade intramedullary nailing...
