    Children with fractures show higher levels of impulsive-hyperactive behavior
    (Lippincott Williams & Wilkins, 2007) Uslu, Murad; Uslu, Runa; Eksioglu, Fatih; Özen, Nurper Erberk
    Children with fractures have been reported to have impulsive-hyperactive behavior problems although whether they exhibited such behavior more often than children with other orthopaedic conditions is unknown. We investigated whether impulsivity-hyperactivity was more prominent in children with extremity fractures than in children with orthopaedic conditions not involving a fracture. From outpatient clinical intakes, we recruited 39 consecutive children with extremity fractures and 33 children with orthopaedic conditions not involving a fracture. We used the Conners' Parent Rating Scale to detect behavioral symptoms in children with and without extremity fractures. Children who were treated for extremity fractures had higher mean scores for impulsivity-hyperactivity than those treated for nontrauma-related reasons. Additionally, more children in the fracture group reached impulsive-hyperactive behavior scores high enough to warrant additional psychiatric evaluation. In terms of injury prevention, the orthopaedic surgeon should be familiar with problem behaviors of children, particularly impulsivity and hyperactivity, to be able to make appropriate referrals for psychiatric evaluation and treatment.

    Computerized tomography scout view for determining distal femoral resection angle in intramedullary instrumentation of total knee arthroplasty
    (Springer, 2007) Uslu, M. Murad; Özsar, Barış; Çirpar, Meriç; Kara, Simay; Eksioglu, Fatih; Çetik, Özgür
    This study aims to investigate the results of distal femoral resection by determining the difference between mechanical and anatomical axes of femur using computerized tomography (CT) scout views in pre-operative planning of total knee arthroplasty. CT scout view of the lower extremities was taken before and after the operation in 16 patients undergoing total knee arthroplasty. Distal femoral resection was performed according to the previously determined ideal resection angle (IRA) using intramedullary instrumentation. At post-operative scanogram, femoral component deviation (FCD) was measured. The results were statistically analyzed. The average IRA was 6.95 (5-9) degrees. At post-operative measurements, the average FCD was 0.63 (0-3) degrees. CT scout films improve the accuracy in distal femoral resection and femoral component alignment.

    Etiology of senile osteoporosis - A hypothesis
    (Springer, 2006) Atık, O. Sahap; Uslu, M. Murad; Eksioglu, Fatih; Satana, Tolgay
    Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear. Based on the available experimental and clinical evidence, we update our earlier proposal that zinc deficiency plays a role in the pathogenesis of senile osteoporosis. However, the mechanism of zinc deficiency in osteoporosis remains unclear. Zinc deficiency may lead to the increase of endogenous heparin probably causing degranulation of mast cells and release of endogenous heparin, and an increase in the bone-resorbing effect of prostaglandin E2. Endogenous heparin and prostaglandin E2 are probably cofactors of parathyroid hormone and may have a role in the pathogenesis of senile osteoporosis enhancing the action of parathyroid hormone. Therefore, zinc replacement by dietary zinc supplementation might be valuable to prevent or treat senile osteoporosis. Additional studies are necessary for the evaluation of the possible role of zinc in the etiology of senile osteoporosis.

    Histological alterations after irradiation of cartilage using Ho: YAG laser
    (Mary Ann Liebert Inc Publ, 2003) Atik, OS; Erdoğan, Deniz; Ömeroğlu, Suna; Korkusuz, Feza; Uslu, Murad M.; Eksioglu, Fatih
    The authors carried out an experimental study to evaluate the histological alterations after irradiation of cartilage using Holmium:YAG (Ho:YAG) laser VersaPulse Select 60 watts and Infra. Tome Delivery Systems 30degrees Handpiece (spot size at fiber tip 0.4 mm; Coherent Medical, Palo Alto, CA). Background Data: Recently, some authors reported cases with articular cartilage damage following arthroscopic laser surgery in the knee joint for the treatment of articular cartilage or meniscal pathology. Materials and Methods: The cartilage specimens immersed in saline were exposed to Ho:YAG laser irradiation. The laser wavelength was 2.1 mum, and pulse duration was 250 musec. Power settings were 0.2-1 joules per pulse and 10-15 Hz. Total laser energy used in these procedures was 1.5 K joules. During the procedures, the handpiece was used at an angle of 30degrees and at a distance of 1 mm. Results: Electron microscopic evaluation demonstrated that the ultrastructure of the cartilage is preserved in both experiment and control groups. Conclusion: When Ho:YAG laser is used in optimal dosage (optimal joule and Hertz) with optimal technique (keeping the handpiece at an appropriate angle and distance) and avoiding overtreatment, it does not cause cartilage damage.

    Localized pigmented villonodular synovitis of the knee: acute onset in pregnancy
    (Springer, 2006) Uslu, Murad; Çetik, Özgür; Atasoy, Pınar; Eksioglu, Fatih; Engin, Murat
    A pregnant patient in the first trimester presented with acute onset knee pain and effusion. As the clinical status was mimicking septic arthritis, surgery was performed. Arthroscopy demonstrated a local synovial tumor and excision was performed with arthrotomy. Microscopic evaluation revealed localized pigmented villonodular synovitis. Due to the presence of necrosis and hematoma in the tumor, we hypothesize that, that torsion or bleeding of the tumor in the presence of physiological pregnancy- related metabolic changes might have been the cause of acute presentation.

    Rotational deformity affects radiographic measurements in distal radius malunion
    (Springer, 2011) Cirpar, Meric; Gudemez, Eftal; Cetik, Ozgur; Turker, Mehmet; Eksioglu, Fatih
    Malunited distal radius fractures are 3D deformities. The preoperative evaluation of the deformity and surgical planning are usually depended on plain radiographic measurements for corrective osteotomies. In most of the cases, the rotational deformity is disregarded in preoperative planning. We aimed to clarify the effect of rotational deformity on radial inclination and dorsal or volar tilt measurements, which are commonly used as radiologic parameters. This study was performed on standard left radius saw bone models. The malunion models were prepared according to AO distal radius fracture classification system in four main and seventeen subgroups. The differences between the mean radial inclination, volar or dorsal tilt measurements performed on plain radiographies and gold standard values were statistically analyzed. Results showed that rotational deformity causes faulty measurements of radial inclination and dorsal tilt on plain radiographies which may be a contributing factor for unsatisfactory clinical results of corrective osteotomy. We suggest 3D preoperative evaluation of the deformity if possible.
