Background The Ganz’ periacetabular osteotomy (PAO) consists of four technically
challenging osteotomies (OT), namely, supraacetabular (saOT), pubic (pOT), ischial (iOT), and …

Background: Sacral-alar-iliac (SAI) screws are increasingly used for lumbo-pelvic fixation
procedures. Insertion of SAI screws is technically challenging, and surgeons often rely on …

Background An optimal osteotomy angle avoids shortening of the first metatarsal bone after
hallux valgus surgery and therefore reduces the risk of transfer-metatarsalgia. The purpose …

Background aims Stem cells participate in vascular regeneration following critical ischemia.
However, their angiogenic and remodeling properties, as well as their role in ischemia-…

Background: While pyogenic spondylodiscitis due to Gram-positive aerobic bacteria and its
treatment is well known, spondylodiscitis caused by anaerobic Gram-negative pathogen is …
