Same-stage total knee arthroplasty and osteotomy for osteoarthritis with extra-articular deformity. Part II: Femoral osteotomy, prospective study of 6 cases.

Background: Same-stage (1S) total knee arthroplasty (TKA) and femoral osteotomy (FO) may deserve consideration in patients with both knee osteoarthritis and severe extra-articular knee deformity (EKD). The objective of this study was to assess clinical and radiological outcomes and morbidity (complications and revisions) in 6 patients managed with S1-TKA-FO.

Hypothesis: 1S-TKA-FO produces satisfactory outcomes and is not associated with higher morbidity rates compared to two-stage TKA-TO or TKA with intra-articular EKD correction, while also significantly shortening total treatment duration.

Return to sports and functional results after revision anterior cruciate ligament reconstruction by fascia lata autograft.

Introduction: The surgical revision rate following anterior cruciate ligament (ACL) surgery is 3% at 2 years and 4% at 5 years. Revision ACL surgery raises the question of the type of graft to be used. The present study assessed return to sports and functional results after revision ACL reconstruction by fascia lata graft.

High throughput-per-footprint inertial focusing.

Matching the scale of microfluidic flow systems with that of microelectronic chips for realizing monolithically integrated systems still needs to be accomplished. However, this is appealing only if such re-scaling does not compromise the fluidic throughput. This is related to the fact that the cost of microelectronic circuits primarily depends on the layout footprint, while the performance of many microfluidic systems, like flow cytometers, is measured by the throughput.

Pneumorachis: a possible source of traumatic cord compression.

The presence of air within the spinal canal secondary to trauma is a rare condition. These rare cases are generally asymptomatic. We report our first case of closed thoracic trauma with pneumorachis associated with neurological disorders.

Four-part fracture after intrathoracic displacement of the humeral head: a case report and review of the literature.

Displaced four-part fracture dislocation represents the highest risk of osteonecrosis of the humeral head due to a disruption of the blood supply. In a few cases, that dislocation can be intrathoracic which worsens prognosis with life-threatening injuries such as hemothorax or pneumothorax. This paper presents the case of a 77-year-old woman after having fallen down the stairs with an intrathoracic dislocation four-part fracture leaving the head in the thorax.
