distraction rate, the less the healing index and consolidation time. Conclusion. Age has the most effect on healing index and consolidation time. Metacarpal lengthening using callus distraction is recommended. Adolescence is the most appropriate time to perform distraction lengthening of a congenitally short metacarpal. This will avoid additional lengthening of normal metacarpals prior to epiphyseal closure.

Objective:To evaluate the effect of inguinal operations performed with a modified Ferguson technique upon testicular volume and blood flow.Methods:This study involved 23 children receiving surgery for inguinal hernia, hydrocele, and cord cyst. This was a prospective study performed between April 2016 and June 2016 in a medical faculty pediatric surgery unit. The color Doppler ultrasound (CDUS) was used to assess testicular volume and blood flow before and after a modified Ferguson technique surgery. The pre- and post operative testicular volume and blood flow were compared with the contralateral testes. SPSS software was used to statistically analyze the data arising; the Mann-Whitney U test and Friedman test were used to compare samples, and P<0.05 was accepted as statistically significant.Results:Preoperative and postoperative testicular volumes were not statistically different when compared to contralateral testes. In patients with right sided inguinal pathology, testicular blood flow on the right side was significantly lower than that on the left side (P=0.023). The testicular blood flow was not statistically different compared with the contralateral testes during the first week evaluation and first month evaluation. The blood flow, probably reduced due to the pressure caused by inguinal pathology, was normalized through surgery.Conclusions:The modified Ferguson technique do not change the testes volume and blood flow.

The purpose of this study was to evaluate the median nerve sonographically and estimate the prevalence of carpal tunnel syndrome (CTS) in computer mouse users. Forty-nine right wrists of 49 employees who had used a computer mouse were included in the study. Thirty-three right wrists of 33 non-mouse user employees were studied as a control group. Both the mouse user and non-mouse user employees underwent sonography and electromyography (EMG). Axial sonograms of the median nerve were obtained proximally, in the middle and distally in the carpal tunnel. At each level, flattening ratio and the cross-sectional area of the median nerve were calculated. We found no significant difference in any parameters between mouse users and control group ( p>0.05). However, when we compared mouse users according to the presence of pain, there was a significant increase in the cross-sectional area of the median nerve proximally in the mouse users having pain ( p<0.05). Of all mouse users, eight (16.3%) were diagnosed as sensory CTS, four (8.2%) as motor CTS by EMG. We also found that four (50%) CTS patients had a proximal cross-sectional area of median nerve exceeding 10 mm2 and five (62.5%) had a distal flattening ratio over three. Prolonged use of a mouse may pose an occupational risk for employees. Sonography can serve as an initial step in symptomatic patients for diagnosis of CTS.
