Surgical treatment of osteopetrosis-related femoral fractures: two case reports and literature review.

Osteopetrosis is a rare hereditary disease which is characterized by increased bone density. Bone resorption is insufficient or fails due to the osteoclast defect in osteopetrosis. Half of the patients are asymptomatic and diagnosed incidentally or based on the presence of fracture.

Influence of 1800 MHz GSM-like electromagnetic radiation exposure on fracture healing.

Background And Aims: In this study, we aimed to investigate whether 1800 MHz frequency electromagnetic radiation (EMR) has an effect on bone healing.

Methods: A total of 30 Wistar albino rats were divided into two equal groups. Fractures were created in the right tibias of all rats; next, intramedullary fixations with K-wire were performed.

[Anterior cruciate ligament injuries: does surgical treatment with autograft versus allograft option affect the clinical results?].

Background: We investigated the clinical outcome of anterior cruciate ligament (ACL) reconstructions with allograft or autograft.

Methods: We retrospectively evaluated 82 patients who underwent arthroscopic ACL reconstruction with anterior tibial tendon (ATT) allograft (n = 52) or quadrupled hamstring tendon (QHT) autograft (n = 30). The patients were assessed using the IKDC (International Knee Documentation Committee) and Lysholm knee scores and functional (one leg hop) and laxity (pivot-shift, Lachman, anterior drawer) tests.

[Effect of bone cement application on the incidence of deep vein thrombosis in major joint arthroplasties].

Objectives: In this study, we have investigated whether the application of bone cement has an effect on the frequency of deep vein thrombosis (DVT) in major joint arthroplasties (MJA).

Patients And Methods: A total of 95 MJA cases meeting the inclusion criteria of this study between January 2004 and January 2005 were divided into cemented and cementless groups. For prophylaxis, all patients were given low molecular weight heparin (LMWH).

Does scapular elevation occur with glenohumeral flexion and abduction? A study through open magnetic resonance imaging and autopsy.

Objectives: This study aims to reveal whether there is an elevation in scapula during flexion and abduction of the glenohumeral joint.

Patients And Methods: In the first stage of our study 32 subjects were randomly divided into two groups. The mobility of the scapular notch was examined using open magnetic resonance imaging (MRI) assay when the glenohumeral joint was in flexion in the first group (5 males, 10 females; mean age 21.

Oral vitamin C and E combination modulates blood lipid peroxidation and antioxidant vitamin levels in maximal exercising basketball players.

Oxidative stress occurs during maximal exercise, perhaps as a result of increased consumption of oxygen. Vitamins C and E can overcome the effects of antioxidants in exercise. We investigated the effects of supplementation with a combination of vitamin C and E (VCE) on blood lipid peroxidation (LP) and antioxidant levels following maximal training in basketball players.

Accuracy of the Polar S810i(TM) Heart Rate Monitor and the Sensewear Pro Armband(TM) to Estimate Energy Expenditure of Indoor Rowing Exercise in Overweight and Obese Individuals.

Accurately assessing the energy expenditure (EE) of different types of physical activity is important for exercise prescription in obese individuals. The aim of this study was to examine the accuracy of the Polar S810i Heart Rate Monitor and SenseWear Pro Armband (SWA) for estimating energy expenditure (EE) during indoor rowing versus indirect calorimetry (IC). 43 overweight and obese adults (16 men, 27 women, BMI = 31.

Effect of electromagnetic field induced by radio frequency waves at 900 to 1800 MHz on bone mineral density of iliac bone wings.

Objective: Telecommunication has gained a different meaning in daily life with the introduction of the mobile phone system. However, electromagnetic pollution has increased in parallel to this improvement. In this study, we aimed to investigate the effects of electromagnetic waves emitted from cellular phones operating at a frequency of 900 to 1800 MHz on the bone mineral density of the human iliac bone wings, which are the most common carriage sites for mobile phones.

Influence of custom-made mouth guards on strength, speed and anaerobic performance of taekwondo athletes.

The purpose of this study was to test the influence of custom-made mouth guards on strength and anaerobic performance of taekwondo athletes. The study included 21 (11 male and 10 female) trained subjects participating in taekwondo. Anaerobic power and anaerobic capacity, isokinetic quadriceps and hamstring strength, handgrip strength, isometric lower extremity and back strength, 20 m sprint time, squat and counter movement jumping height were measured in two randomized conditions: with or without custom-made (CM) mouth guards.

[The efficacy of low- and high-molecular-weight hyaluronic acid applications after arthroscopic debridement in patients with osteoarthritis of the knee].

Objectives: We evaluated the efficacy of viscosupplementation with low- or high-molecular-weight hyaluronic acid (HA) preparations following arthroscopic debridement (AD) in patients with osteoarthritis of the knee.

Methods: The study included 45 patients (19 men, 26 women; mean age 53 years; range 41 to 66 years) with Kellgren-Lawrence grade 2-3 osteoarthritis of the knee. Following AD, the patients were randomized to three groups to receive three intra-articular injections of 2 ml hylan G-F 20 (Synvisc, n=16), five intra-articular injections of 2 ml sodium hyaluronate (Hyalgan, n=14), and no injections (controls, n=15).

The effect of arthroscopic surgery and intraarticular drug injection to the antioxidation system and lipid peroxidation at osteoarthritis of knee.

Objective: To elucidate the effects of arthroscopy and intraarticular hyaluronan therapies on antioxidant enzyme activity and lipid peroxidation.

Methods: This study was conducted between January and May 2005, at the Department of Orthopedics and Traumatology, Suleyman Demirel University, Isparta, Turkey. A total of 60 patients with knee pain who were diagnosed as knee osteoarthritis according to the American College of Rheumatology (ACR) criteria were included in this study and randomly and equally divided into 4 groups.

Comparison of buccal and intramuscular dexmedetomidine premedication for arthroscopic knee surgery.

Study Objective: To compare the sedative, anxiolytic, analgesic, hemodynamic, and respiratory effects of buccal dexmedetomidine with intramuscular (IM) dexmedetomidine for premedication in patients undergoing arthroscopic knee surgery during spinal anesthesia.

Design: Randomized, placebo-controlled trial.

Setting: University medical center.

Do custom-made mouth guards have negative effects on aerobic performance capacity of athletes?

Mouth guards are considered an essential part of equipment for athletes participating in contact sports. The purpose of this study was to evaluate the effect of custom-made mouth guards on the ventilatory gas exchange effects of taekwondo athletes. The subjects were 22 elite athletes aged between 14 and 17 years.

A regression equation to predict true maximal oxygen consumption of taekwondo athletes using a field test.

Objective: The purpose of the present study was to examine the validity of using a 20 meter multistage shuttle run test to estimate maximal oxygen uptake.

Methods: Twenty-two elite taekwondo athletes (11 male, 11 female, members of the Turkish young national team), participated in the study. The respiratory gas exchange parameters were measured using portable gas analysis system while shuttle run test was carried out.

Dental trauma incidence and mouthguard use in elite athletes in Turkey.

Contact sports may lead to dental trauma, which often can be reduced with appropriate preventive measures. While numerous studies exist on this topic for several countries throughout the world, there is a lack of comprehensive descriptive studies in Turkey. The purpose of this study was to investigate the incidence and type of dental injuries associated with three different sports among Turkish elite athletes, who do not contact (volleyball), contact directly (taekwondo) or indirectly (handball) with competition rivals.

Multiple loose bodies in the joints: from snowstorm to hailstones.

We report the cases of 2 young-adult patients with multiple loose bodies, one in the knee and the other in the elbow joint. Loose bodies were composed of hundreds of brilliant white particles up to 5 mm in the first patient, who had a history of pain and swelling. From the right elbow joint of the second patient, arthroscopic removal of about 25 osteocartilaginous loose bodies, ranging from 5 to 14 mm in diameter, was performed.
