Article : The minimal invasive periacetabular osteotomy (PAO) for adult hip dysplasia surgical tips and tricks By GI Wassilew, V. Janz, J. Löchel, A. Hofer, R. Kasch
In 1988, Ganz et al. first described the surgical procedure of periacetabular osteotomy (PAO) for acetabular reorientation. PAO is an extensive surgical procedure performed in young adults with symptomatic DDH to improve function of the hip joint and delay the development of secondary osteoarthritis.
Article : Mechanical alignment alternatives: From anatomical to kinematic alignment in total knee arthroplasty By Sébastien Lustig*, Elliot Sappey Marinier*, Frederic Sailhan**, Emmanuel Marchetti***, Pascal Duffiet****, David Benzaquen*****, Charles Rivière******
Traditionally for the last 4 decades, the best outcome for a total knee arthroplasty (TKA) was seen with the mechanical alignment (MA) concept aiming for a neutral leg axis (180° mechanical femorotibial angle). At the same time, the MA technique aligns the femoral and tibial component frontally in 90° to the mechanical axis in order to create a femorotibial joint line perpendicular to the neutral mechanical axis.
Article : Management of tibial plateau fractures: diagnostics, classification and treatment By Julian Ross(1), Karl-Heinz Frosh(II)
Approximately 1-2 % of all bony injuries are represented by tibial plateau fractures. Its complexity and associated soft tissue injuries can be a challenge for surgical skills. An anatomic reduction and stable fixation are of crucial importance in order to achieve rapid mobilization, improved rehabilitation and to minimize posttraumatic osteoarthritis.
Article : Total hip arthroplasty planning : Limits of x-ray and contribution of the CT-scan By Christophe Castelain
Since the time of Maurice Muller in the 1980s, total hip arthroplasty has been planned using the reference standard x-ray method. Image digitisation and CT have since been used to develop high-performance planning software. In a large number of pathologies, CT has outmatched x-ray with its millimetric precision and three-dimensional image display. After seven years using CT-based planning software and comparing it with standard x-ray, I was able to see the shortfalls of conventional x-ray more clearly.
