Minimally invasive plate osteosynthesis with PHILOS plate for proximal humerus fractures.

Objectives: The aim of the present study was to evaluate results, including clinical and radiological outcomes and number of complications, following minimally invasive plate osteosynthesis (MIPO) of proximal humerus fractures, using the PHILOS® proximal humerus internal locking system (Synthes Holding AG, Solothurn, Switzerland).

Methods: Retrospectively evaluated were 31 patients treated with MIPO (12 male, 19 female; average age: 58.4 years).

The effects of low-dose radiotherapy on fresh osteochondral allografts: An experimental study in rabbits.

Objective: The aim of this study was to investigate the effects of low-dose fractionated radiotherapy on cartilage degeneration after distal femoral fresh massive osteochondral allograft transplantation.

Methods: Twenty-four New Zealand White rabbits were divided into three groups of 8 rabbits each. All rabbits underwent distal femoral medial condyle fresh massive osteochondral allograft transplantation from California rabbits.

Avascular necrosis and nonunion after osteosynthesis of femoral neck fractures: effect of fracture displacement and time to surgery.

This study assessed the effect of fracture displacement and elapsed time before surgery on the development of avascular necrosis and nonunion after internal fixation of femoral neck fractures. Twenty-eight patients with 30 femoral neck fractures who underwent internal fixation and completed a minimum of 2 years' follow-up were retrospectively analyzed. The rates of avascular necrosis and nonunion were 12.
