STUDY DESIGN: Eighty-four patients who had been treated for degenerative spinal diseases between January 2006 and June 2009 were reviewed retrospectively. PURPOSE: We aimed to compare the clinical and radiologic findings of manual workers who underwent posterolateral fusion (PLF) or posterior interbody fusion (PLIF) involving fusion of 3 or more levels of the spine. OVERVIEW OF LITERATURE: Previous studies have concluded that there is no significant difference between the clinical outcome of PLF and PLIF techniques. METHODS: After standard decompression, 42 patients underwent PLF and the other 42 patients underwent PLIF. Radiologic findings, Oswestry disability index (ODI) scores, and visual analogue scale (VAS) scores were assessed preoperatively and at 6-month intervals postoperatively and return to work times/rates were assessed for 48 months. RESULTS: Patients who underwent PLF had significantly shorter surgical time and less blood loss. According to the 48-month clinical results, ODI and VAS scores were reduced significantly in the two groups, but the PLIF group showed better results than the PLF group at the last follow-up. Return to work rate was 63% in the PLF group and 87% in the PLIF group. Union rates were found to be 81% and 89%, respectively, after 24 months (p=0.154). CONCLUSIONS: PLIF is a preferable technique with respect to stability and correction, but the result does not depend on only the fusion rates. Discectomy and fusion mass localization should be considered for achieving clinical success with the fusion technique. Before performing PLIF, the association of the long operative time and high blood loss with mortality and morbidity should be taken into consideration, particularly in the elderly and disabled patients.

PURPOSE: The aim of study was to determine the level of the radiation exposure of surgical staff during surgical probe applications in breast cancer. METHODS: Three operations of a sentinel lymph node biopsy were randomly selected. Spaced circles (50 cm apart) were drawn surrounding the operation bed on the floor. Tc-99m nanocolloid was injected peritumorally and intradermally into a patient. The radiation dose was measured with a GeigerMueller counter placed according to the drawn circles at distances of 50-200 cm from the side of patient's head and bilateral chest while the patient lay on the operation bed. All of the surgical procedures were recorded with a video camera and were monitored. RESULTS: The whole body dose to the senior surgeon was calculated as 2.00-4.70 microSv which means that a senior surgeon can perform 212-500 procedures per year to reach the annual International Commission on Radiological Protection radiation dose limit for a member of the public. CONCLUSION: We concluded that radiation risk to the surgical staff is low from sentinel node detection with the use of radiocolloids.
