ABSTRACT
PURPOSE: This study compared the surgical results of various posterolateral corner sling methods performed through either the fibula head tunnel or tibia tunnel in patients with chronic PLRI (PosteroLateral Rotatory Instability). MATERIALS AND METHODS: Between January 1999 and October 2003, 20 and 19 patients who had undergone surgery for PCL (posterior cruciate ligament) tensioning and an ALB (anterolateral bundle) reconstruction through the fibula head tunnel or tibia tunnel, respectively and were followed up more than 1 year were enrolled in this study. RESULTS: The fibular head tunnel was found to be superior compared with the tibia tunnel method in terms of the operation time (36.5+/-7.5 versus 68.4+/-12.8) (p<0.0001), rotational stability (p= 0.0018) and IKDC objective score (p<0.0001). In the fibula head tunnel group, 85% of patients had an equal to normal or tighter than normal rotational stability in the tibial tunnel group with 63% having an equal to normal or tighter than normal side at the last evaluation. In the IKDC objective score, 85% of patients in the fibula head tunnel group had a rating B or higher at the last evaluation compared with 79% in the tibial tunnel group (p<0.0001). However there were no significant differences in anteroposterior stability and OAK score. CONCLUSION: The modified posterolateral corner sling through the fibula head tunnel produces better results in terms of a posterolateral rotational stability of grade II chronic PLRL in a combined PCL injury than that using the tibia tunnel method.

PURPOSE: To evaluate the clinical results of femoral shaft fracture treated by Intramedullary (IM) nailing through skeletal traction compared with manual traction on a radiolucent table. MATERIALS AND METHODS: Thirty cases with femoral shaft fracture treated with closed IM nailing from January 2000 to June 2002 were divided into two groups; fifteen fractures reduced by manual traction (Group A) and fifteen fractures reduced by skeletal traction (Group B) on a radiolucent table. The number of people participated in the operations, operation and radiation exposure time, and post-operative complications were evaluated. RESULTS: The number of people participated in the operations was five in Group A and four in Group B. The average operation time was 116 minutes and 82 minutes (p<0.001). The radiation exposure time was 2.8 minutes and 1.2 minutes (p<0.001). However, there was no significant difference in the post-operative complications such as shortening or lengthening of bone between two groups. CONCLUSION: There was no significant difference in the operative outcome between two groups. However, skeletal traction has positive effects of reducing the operation time, radiation exposure time, and number of people participating in the operations. Also, regarding the consistent traction power, skeletal traction is the better treatment modality in maintaining the alignment and length of femoral bone than manual traction.
