    Deformity correction by Ilizarov distraction osteogenesis after distal radius physeal arrest
    (TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2011) Gundes, Hakan; Buluc, Levent; Sahin, Mustafa; Alici, Tugrul
    Objective: The aim of this study was to evaluate the results of osteotomy and distraction osteogenesis using Ilizarov circular external fixator to treat radial shortening and severe wrist deformity due to neglected post-traumatic distal radius physeal arrest. Methods: The study retrospectively reviewed 4 patients (4 males; average age: 16 years; range: 14 to 19 years) who underwent osteotomy and distraction osteogenesis to treat radial shortening and severe wrist deformity due to neglected distal radius physeal arrest. Mean interval between trauma and surgical intervention was 8 (range: 4 to 12) years and mean follow-up time was 83 (range: 40 to 126) months. Patients were evaluated with radiographic measurements (shortening and lengthening ratio, radioulnar joint leveling, distal radioulnar joint congruency), objective functional measurements (grip and pinch strength, range of motion measurements [ROM]) and subjective functional measurements (Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire and Mayo wrist score). Statistical analysis was made using the Mann-Whitney U non-parametric test. Results: Radiographic measurements were obtained preoperatively and at the final follow-up. The mean shortening ratio of the radius was 14.6% (range: 9.3% to 18.7%) and mean lengthening ratio was 15.9% (range: 13.2% to 18.3%). Normal distal radioulnar joint leveling and distal radioulnar congruency resembling a joint was established in all but one patient with four millimeters of ulna plus deformity. According to the Mann-Whitney U non-parametric test, there was no statistical difference in grip and pinch power, ROM on flexion/extension, and ulnar/radial deviation axis between the operated and non-operated sides. There was statistically significant pronation/supination restriction between the operated and non-operated sides (p<0.04). Mean DASH score was 2.07 (range: 0.0 to 8.3) and the mean Mayo wrist score was 89 (range: 75 to 100) points. According to the Mayo wrist score, results were excellent in one patient, good in two patients, and satisfactory in one patient. Conclusion: The use of distal metaphyseal osteotomy and Ilizarov distraction osteogenesis is a viable treatment method for neglected physeal fractures of the distal radius as it establishes acceptable deformity correction and a functional wrist joint.

    Effects of Anthropometric Factors on Nerve Conduction An Electrophysiologic Study of Feet
    (AMER PODIATRIC MED ASSOC, 2013) Cinar, Nilgun; Sahin, Sevki; Sahin, Mustafa; Okluoglu, Tugba; Karsidag, Sibel
    Background: Previous studies have shown that age, sex, and body mass index (BMI) affect the amplitude of sensory nerve action potentials (SNAPs), but the total effects of multiple factors and the most prominently affected nerves have not been elucidated. We systematically investigated the effects of these factors on motor and sensory nerves of the feet. Methods: The amplitude, latency, and conduction velocity of compound muscle action potential (CMAP), SNAP, and mixed nerve action potential (MNAP) of the posterior tibial, calcaneal, distal posterior tibial, medial and lateral plantar, and sural nerves were measured in 30 healthy individuals (60 feet). The effects of age, sex, height, and BMI on each nerve were estimated by correlation and linear regression analyses. Results: The amplitude of posterior tibial CMAP and distal posterior tibial MNAP decreased with BMI. The amplitude of medial plantar MNAP and sural SNAP decreased with height. The conduction velocity of calcaneal SNAP and distal posterior tibial and lateral plantar MNAP decreased with height and BMI. The conduction velocity of medial plantar MNAP decreased only with height. The latency of posterior tibial CMAP increased with age and height. The latency of lateral plantar CMAP and calcaneal SNAP increased with height. The latency of lateral plantar MNAP increased with BMI. Conclusions: The effects of age, sex, height, and BMI in foot nerve conduction studies are not identical. Height and BMI were shown to strongly affect motor, sensory, and mixed nerve conduction. Further investigations are needed. (J Am Podiatr Med Assoc 103(1): 43-49, 2013)

    Unicameral bone cyst of the lunate in an adult: case report
    (BIOMED CENTRAL LTD, 2010) Gundes, Hakan; Sahin, Mustafa; Alici, Tugrul
    We report a case of a symptomatic unicameral (simple) bone cyst of the lunate in a 42-year- old woman. The lesion was treated with curettage and cancellous autogenous iliac bone grafting. At five years of follow-up the wrist was pain free, there were no limitations of motion, and the radiographs showed complete obliteration of the cavity. To the best of our knowledge, no other unicameral bone cyst of the lunate has been reported in an adult. Cysts with significant cavities at the carpal bones in an adult should be approached cautiously, as they may require early curettage and bone grafting for healing, before collapse and degenerative changes occur.
