Effect of hyperbaric oxygen and ozone preconditioning on oxidative/nitrosative stress induced by tourniquet ischemia/reperfusion in rat skeletal muscle.
The aim of the study was to investigate the effect of hyperbaric oxygen-preconditioning (HBO-PC) and ozone-preconditioning (O3-PC) on oxidative/nitrosative stress induced by tourniquet ischemia/reperfusion (I/R) in rat skeletal muscle. ⋯ Both O3-PC and HBO-PC reduced tissue lipid peroxidation, NOx levels, and iNOS staining scores in the experimental I/R model. Our data suggest that HBO-PC and O3-PC protect against oxidative/nitrosative stress induced by I/R in rat skeletal muscle.

Randomized Controlled Trial Comparative Study[The effects of two different continuous passive motion protocols on knee range of motion after total knee arthroplasty: a prospective analysis].
We prospectively evaluated the effects of continuous passive motion (CPM) started after two different time intervals following total knee arthroplasty (TKA) on short- and long-term results, in comparison with standard physical therapy. ⋯ Even though CPM protocols applied following TKA may shorten the length of hospital stay, CPM applications do not offer additional short- and long-term benefits over standard physical therapy with respect to knee flexion and clinical and functional results.

Case Reports[Percutaneous iliolumbar screw fixation in a patient with unstable pelvic fracture and transitional lumbar vertebrae and cadaveric illustration of the fixation].
Unstable pelvic ring fractures cause high rates of morbidity and mortality. Percutaneous iliosacral screws provide a safe pelvic fixation obviating large surgical exposures. The presence of transitional vertebrae may present difficulties in numbering and fluoroscopic identification of lumbar discs and vertebrae. ⋯ No neurologic or vascular complications were seen and the patient returned to his preinjury work and was pain-free in the second postoperative year. In order to determine the anatomic relationship of the iliolumbar screw with the major neurovascular structures, a cadaveric study was performed on the corpse of an adult man. Following dissection, it was observed that the iliolumbar screw inserted from the lateral wall of the iliac wing passed through the iliopsoas muscle and advanced to the L(5) vertebral corpus posterior to the fourth and fifth lumbar roots and with a reasonably distant course from the common iliac veins and arteries.

[The relationship between anterior knee pain occurring after tibial intramedullary nailing and the localization of the nail in the proximal tibia].
We investigated the relationship between the development of postoperative anterior knee pain and the location of the nail in the proximal tibia in patients treated with locked intramedullary nailing for tibial diaphyseal fractures. ⋯ Our findings suggest that the distances from the nail to the tibial plateau and anterior tibial cortex do not have any role in the development of postoperative anterior knee pain.

[Open reduction and low-profile plate and/or screw fixation in the treatment of phalangeal fractures].
We evaluated the functional results and the effectiveness of open reduction and low-profile plate and/or screw fixation in the treatment of phalangeal fractures. ⋯ Our findings do not justify open reduction and low-profile plate and/or screw fixation as the first choice in the treatment of phalangeal fractures. If plate and screw fixation is necessary, the most minimally invasive method such as screw fixation should be preferred.
