    An alternative treatment method for defective pseudoarthrosis le; evaluation of eight patients treated with Artelon plus Kryptonite
    (Acta Medica Belgica, 2016) Uras, Ismail; Yavuz, Osman Yuksel; Uygun, Murat; Paslioglu, Ebubekir; Komurcu, Mahmut
    Pseudoarthrosis with bone loss is one of the most challenging orthopaedic problems for surgeons. Bone loss usually leads to technical difficulties during surgery due to instability in the fracture area. Eight patients with pseudoarthrosis of different long bones were operated on by the same surgeon. The median age was 53 years (25-61), and the median time period after the index operation was 21 months (1272 months). Radiographic union was achieved in all patients in 3.62 months (2-5 months). Efficient healing with new bone formation was observed in all of the patients. The result of the current case series is promising. This treatment method can be used for the treatment of pseudoarthrosis without increasing morbidity. Long-term follow-up and larger case series are needed for evidence of the adequacy and reliability of this method of treatment.

    Does the wedge wing in the neck screw prevent cut-out failure in OTA/AO 31-A2 trochanteric fractures in elderly patients?
    (Acta Medica Belgica, 2014) Gunay, Cuneyd; Atalar, Hakan; Altay, Murat; Yavuz, Osman Yuksel; Yildirim, Ahmet Ozgur; Oken, Ozdamar Fuad
    The purpose of this retrospective study was to evaluate the effects of Dyna Locking Trochanteric (DLT) nail (U & I Corporation 529-1, Yonghyun-dong, Uijungbu Kyunggi-Do, Korea 480-050) in 31-A1 and 31-A2 intertrochanteric femur fractures. Eighty-seven patients (63 female and 24 male, mean age 77 years) were treated. The mean duration of follow-up was 16.6 +/- 3.1 months (range, 12-24 months). There were 36 cases of 31-A1 and 51 cases of 31-A2 fractures. The duration of surgery, fluoroscopy screening time, the blood loss, the hospital stay, the tip-apex distance were significantly less in the 31-A1 fracture group compared with the 31-A2 fracture group (p < 0.001). Cut-out was observed in 13 patients (14.9%) above 80 years old with 31-A2 fractures. Especially in elderly patients with unstable 31-A2 fractures, the wedge wing on the neck screw does not work properly. Therefore further biomechanical investigations and also prospective clinical studies with larger series are needed to improve the device.

    Effects of cepae extract, allantoin, and heparin mixture on developing and already formed epidural fibrosis in a rat laminectomy model
    (Tubitak Scientific & Technological Research Council Turkey, 2016) Ozay, Rafet; Yavuz, Osman Yuksel; Aktas, Abit; Yigit, Funda; Cetinalp, Nuri Eralp; Ozdemir, Haci Mustafa; Sekerci, Zeki
    Background/aim: The study was designed to investigate whether local administration of a mixture composed of cepae extract, allantoin, and heparin (CAH) decreased already formed epidural fibrosis (EF) at the laminectomy site. Materials and methods: Twenty- four adult male Sprague Dawley rats were equally divided into four groups. Laminectomy was performed at the L5 level in all rats. The group 2 and group 4 rats were treated with local drug administration. While the group 1 and 2 rats were sacrificed after 6 weeks, the remaining rats were reoperated and CAH mixture was applied in group 4. The vertebral columns of all rats were removed en bloc. Fibroblast numbers, EF, and arachnoidal involvement (AI) were evaluated. Results: The results of the treatment groups were separately compared with the control groups. The numbers of fibroblasts in the treatment groups were significantly lower than those in the control groups (P < 0.001). The grade of EF in group 2 was significantly less than that in group 1 (P < 0.05). There was no statistically significant difference regarding EF and AI grade between group 3 and group 4, and local application of the drug on EF and AI yielded better results than in the control groups. Conclusion: The mixture composed of CAH might be a successful candidate for preventing EF in clinical practice.

    Maternal Height and Infant Body Mass Index Are Possible Risk Factors for Developmental Dysplasia of the Hip in Female Infants
    (Okayama Univ Med School, 2015) Atalar, Hakan; Gunay, Cuneyd; Yavuz, Osman Yuksel; Camurdan, Aysu Duyan; Uras, Ismail; Eren, Ali
    Developmental dysplasia of the hip (DDH) is a wide-spectrum disease with a multifactorial etiology and, despite its prevalence, no definitive etiology has yet been established. The aim of this study was to investigate new risk factors for DDH by evaluating newly defined potential risk factors. A total of 71 infants were separated into 2 groups: Group 1, 28 female first-born infants diagnosed with DDH and their mothers; and Group II, 43 healthy female first-born infants and their mothers. The maternal height and weight before pregnancy, infant height and weight at birth, and body mass index (BMI) of both mother and infant were determined. Calculations were made of the ratios between these parameters. Of the examined risk factors, only maternal height and the ratio of maternal height to infant BMI (MH/I-BMI) were found to be significant for DDH in infants. In conclusion, the results of this study show that a short maternal height and a low MH/I-BMI increase the risk of DDH. Further studies with a larger series are necessary to confirm these results.

    Our Experiences in the Surgical Treatment of Bayne Type III and IV Radial Longitudinal Deficiencies
    (Modestum Ltd, 2015) Komurcu, Mahmut; Yuce, Serdar; Yavuz, Osman Yuksel; Uras, Ismail; Uygun, Murat; Kurklu, Mustafa
    Radial longitudinal deficiencies are characterized by radial deviation of the wrist, a short and bowed forearm and a non-functional or absent thumb. The deformity is caused by varying degrees of underdevelopment and malformation including hypoplasia of the bones, joints, muscles, tendons, ligaments, nerves and vessels. This study describes our results from centralization in 8 limbs with Bayne type III-IV radial longitudinal deficiencies. We reviewed 8 limbs from 6 patients with a centralization performed between 2002 and 2010. The median patient age at the time of the operation was 2.75 years (range 2-14 years). The sex ratio was 4 male and 2 female. All patients underwent centralization. One patient had an additional 6.5 cm elongation of the ulna bone by means of a circular external fixator (CEF). The median follow-up time from centralization was 4,5 years (range 2-10 years). The result was considered to be excellent in 4 cases, good in 3 cases and fair in 1 case. Radial deviations regenerated in all cases. During follow-up, a radial deviation of 15 degrees developed in one patient; this deviation did not require surgical correction. Hand and wrist movements were within acceptable levels. Movement and function of the wrist and forearm can be obtained through centralization of the wrist and ulnar elongation when necessary. A cosmetically pleasant appearance can be ensured.

    The efficacy of semirigid hip orthosis in the delayed treatment of developmental dysplasia of the hip
    (Lippincott Williams & Wilkins, 2014) Uras, Ismail; Yavuz, Osman Yuksel; Uygun, Murat; Yildirim, Hamdullah; Komurcu, Mahmut
    This study assessed the use of semirigid hip orthosis to stabilize the femoral head into the acetabulum in the delayed treatment of developmental dysplasia of the hip (DDH; Graf type IIb or more severe) under the age of 6 months. Ninety-eight hips from 75 patients (four boys, 71 girls) were evaluated retrospectively. The mean age at treatment initiation was 3.2 +/- 1.3 months (1-6 months). As the dysplastic hip matured into a type I hip, we applied the weaning regimen for 1 month. Seventy-two patients (96%) were treated successfully in 4.2 +/- 1.1 months (2-8 months). All of the failures were type IV hips. We did not detect any acetabular or femoral head pathology in the later follow-up. Semirigid hip orthosis is safe and effective as the first-line treatment method for delayed DDH except in type IV hips in patients under 6 months of age.

    Which modality is the best choice in distal radius fractures treated with two different Kirschner wire fixation and immobilization techniques?
    (Turkish Assoc Trauma Emergency Surgery, 2015) Gunay, Cuneyd; Oken, Ozdamar Fuad; Yavuz, Osman Yuksel; Gunay, Sinem Hursen; Atalar, Hakan
    BACKGROUND: The aim of the study was to investigate whether the number and position of Kirschner (K)-wires, and the manner and duration of immobilization influence radiologic and functional outcomes of distal radius fractures treated with percutaneous K-wire fixation. METHODS: Ninety-two patients were included into the study with a mean follow-up period of 19.84 +/- 5.22 months (range, 13-34 months). In Group I, forty-five patients were treated with 3 K-wires and supported with a volar semi-circular cast for the first 3 weeks followed by a removable splint for a further 3 weeks. In Group II, forty-seven patients were treated with 2 K-wires and supported with a below-elbow circular cast for 6 weeks postoperatively. RESULTS: No significant difference in grip strength and DASH scores was found between the two groups. In clinical examination, significantly better functional results were determined in patients supported with a removable volar splint. At 6 weeks postoperatively, volar tilt, radial inclination, and radial length were significantly better in Group I compared to Group II (all p values). CONCLUSION: Tripod technique with 3 K-wires is a safe and reliable procedure to achieve stability and good radiological results. The use of a removable splint also improves the functional outcomes in the treatment of both intra-and extra-articular distal radius fractures.
