Learning and optimizing arthroscopic knot-tying by surgery residents using procedural simulation.

Introduction: Procedural training of orthopedic surgery residents includes learning arthroscopic knot-tying. The models used comprise arthroscopy training modules of increasing complexity, although there is no procedural training guide for the acquisition of arthroscopic knot-tying skills. Few studies have focused on how residents learn arthroscopic knot-tying.

Treatment of moderate hallux valgus by percutaneous, extra-articular reverse-L Chevron (PERC) osteotomy.

Aims: The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy.

Patients And Methods: A total of 38 patients underwent 45 procedures. There were 35 women and three men.

Acetabular component navigation in lateral decubitus based on EOS imaging: A preliminary study of 13 cases.

Introduction: Acetabular component navigation classically requires palpation of the bone landmarks defining the anterior pelvic plane (APP) (anterior superior iliac spine [ASIS] and pubis), the recording of which is not very reliable when performed in lateral decubitus. The objectives of the current experimental study were: (1) to assess the clinical feasibility of NAVEOS navigation (based on EOS imaging) in lateral decubitus; and (2) to compare precision versus classical APP-based navigation (NAVAPP).

Hypothesis: Iliac plane navigation using EOS is as reliable as APP navigation.

Percutaneous bunionette correction: results of a 49-case retrospective study at a mean 34 months' follow-up.

Introduction: Bunionette consists in a lateral prominence of the head of the fifth metatarsal (M5), inducing a callus. Toe malpositioning determines the varus, supraductus or infraductus form.

Hypothesis: A percutaneous method without osteosynthesis was assessed in 38 patients suffering from this pathology.

Preventing surgical-site infections: measures other than antibiotics.

Surgical-site infections (SSIs) due to intra-operative contamination are chiefly ascribable to airborne particles carrying microorganisms, mainly Staphylococcus aureus, which settle on the surgeon's hands and instruments. SSI prevention therefore rests on minimisation of airborne contaminated particle counts, although these have not been demonstrated to correlate significantly with SSI rates. Maintaining clear air in the operating room classically involves the use of ultra clean ventilation systems combining laminar airflow and high-efficiency particulate air filters to create a physical barrier around the surgical table; in addition to a stringent patient preparation protocol, appropriate equipment, and strict operating room discipline on the part of the surgeon and other staff members.
