Öğe Giant-cell tumor of the tendon sheath in the toe(Turkish Joint Diseases Foundation, 2008) Kalacı, Aydıner; Ozkan, Cenk; Sevinc, Teoman Toni; Yanat, Ahmet NedirnGiant-cell tumor of the tendon sheath is a benign, soft-tissue tumor usually arising from synovial cells of the tendon sheaths in the hand. Involvement of the toes is quite rare. We presented three patients including two women with ages 25 and 50 years, and one man aged 21 years, who underwent surgery for mass lesions originating from tendon sheaths of the toe. All the patients presented with a slightly painful soft tissue mass in the toe. Magnetic resonance imaging was not helpful in the differential diagnosis. Diagnosis of the tumors was made by histopathologic evaluation of completely excised lesions. No local recurrences were encountered during a mean follow-up of 18 months.Öğe METACHRONOUS MULTICENTRIC GIANT CELLTUMOR OF THE UPPER LIMB(Istanbul Univ, Faculty Medicine, Publishing Office, 2006) Kalaci, Aydiner; Ozkan, Cenk; Ozbarlas, SerdarMetachronous multicentric giant cell tumor (GCT) of bone is a rare entity. The high recurrence rate after curettage may mean that more aggressive surgical management is mandatory, including en-bloc resection when indicated. We report a young woman presenting with metachronous recurrent benign GCT located at the right proximal humerus and a second lesion at the ipsilateral distal radial metaphysis. The case was successfully treated with an aggressive surgical approach (en-bloc resection).Öğe Morphometry of the thoracolumbar vertebrae in sickle cell disease(Elsevier Sci Ltd, 2010) Serarslan, Yurdal; Kalacı, Aydıner; Ozkan, Cenk; Dogramaci, Yunus; Cokluk, Cengiz; Yanat, Ahmet NedimPatients with sickle cell disease (SCD) who have deformities and vertebral fractures due to osteoporosis may require surgery. Spinal surgeons must become familiar with the vertebral morphometry of patients with SCD and to that aim we have examined the morphometry of the thoracolumbar spine in these patients. A cohort of 100 patients with SCD was examined using plain thoraco lumbar anteroposterior/lateral radiographs and dual energy X-ray absorptiometry (DEXA). Vertebral morphometry (vertebral body diameters, pedicle, spinal canal and deformity) was assessed for different age groups. Results were compared to published studies of healthy subjects. The vertebral dimensions for the 16-20-year and the 21+-year-old groups were significantly smaller for females than males at most spinal levels, while measurements in the 6-10 years and 11-15 years age groups were similar across both sexes at most levels. No significant statistical difference was found between the diameters of the right and left pedicles. With the exception of the sagittal diameter, most of the dimensions of the vertebral bodies measured in SCD patients were less than those of healthy individuals; multiple deformities were also observed. Low bone density was noted in 32 patients. Our data highlight the differences in vertebral bone mineral density, anatomy and deformities in patients with SCD compared to healthy individuals. When considering surgical intervention for patients with SCD, it is important that pre-operative radiography and planning is undertaken, and that the surgeon is familiar with the geometry of the pedicles of the thoracolumbar vertebrae necessary for the safe insertion of pedicle screws. Osteoporosis must be considered when planning surgical interventions in these patients. (C) 2009 Elsevier Ltd.

This series included 21 cases in 12 women and 2 men, with a mean age of 42.3 years. Follow-up averaged 41.2 months. Bone pegs prepared from the resected femoral segment were seated in the medullary canal around the stem for femoral fixation. Merle d'Aubigne scores for pain, motion, and walking improved from 2.9, 4.4, and 3.7 to 5.2, 5.4, and 5.5, respectively. Radiographic union was detected within 12 +/- 3.4 (range, 6-24) weeks in all cases. Complications were early dislocation in 2 cases. This technique allows correction of anteversion, provides excellent rotational stability, and eliminates the need for additional osteosynthesis regardless of the stem design.Öğe Results of using Ilizarov distraction osteogenesis technique for the treatment of cubitus varus deformities in adults(Springer, 2010) Ozkan, Cenk; Dogramaci, Yunus; Kalacı, Aydıner; Gulsen, Mahir; Bayram, HueseyinFive adult patients, with posttraumatic cubitus varus deformity underwent corrective surgery by the Ilizarov method of distraction osteogenesis. A standard technique was applied in all patients. The average follow-up was 28 (range, 24-38) months. Preoperative carrying angle ranged from 12A degrees to 22A degrees of varus (average 16.6A degrees) and postoperative carrying angle ranged from 10A degrees to 14A degrees of valgus (average, 11.6A degrees) equalized to the contralateral side. The outcome was rated as excellent in all patients. No complication was observed, except a grade-2 pin-tract infection in two patients. Rigid fixation, early rehabilitation, precise correction, satisfactory cosmetic scars and functionally excellent results can be obtained with this method.Öğe Revision hip arthroplasty in sickle cell disease(K Faisal Spec Hosp Res Centre, 2007) Kalacy, Aydyner; Ozkan, Cenk[Abstract Not Available]Öğe Two different methods of supracondylar lateral wedge osteotomy in cubitus varus deformity in adults(Turkish Joint Diseases Foundation, 2009) Kalacı, Aydıner; Ozkan, Cenk; Yanat, Ahmet Nedim; Oney, Tayfun; Sever, Gokhan; Dogramaci, YunusObjectives: We reviewed the results of a transverse osteotomy for cubitus varus deformity in adults stabilized by two different methods of fixation with either Kirschner wire (K-wire) or Y plate. Patients and methods: Sixteen soldiers were treated by a lateral closing wedge osteotomy of the distal humerus for cubitus varus deformity in the military infirmary. Two different methods of fixation were used for the osteototny. The osteotomies were stabilized with K-wires in the initial five cases. Because of loosening of the pins and loss of correction in these five cases, Y plates were introduced for fixation in the other patients. Results: Three patients in the K-wire group, and one case in the Y plate fixation group had poor results. Lateral closing wedge osteotomy is technically easy and allows three dimensional correction. Accompanying displaced ulnar nerves and snapping triceps tendons were spontaneously corrected by the osteotomy. Conclusion: Y plates provide rigid fixation that permits early active motion and prevents possible complications related to implant failure or loss of fixation.Öğe What's your diagnosis?: A previously healthy 77-year-old man with a painful mass in the calf for two months -: Diagnosis(K Faisal Spec Hosp Res Centre, 2007) Ozbarlas, Serdar; Kalacı, Aydıner; Ozkan, Cenk; Togrul, Emre[Abstract Not Available]
