Abstract PDF: PURPOSE
To develop a robot-arm type image-guided surgery system for percuatneous screw fixation of the sacro-iliac joint and to evaluate its accuracy.
MATERIALS AND METHODS
We have developed an image-guided surgery system using a three-dimensional digitizer (Microscribe 3-D G2, Immersion, USA) and a personal computer. The registration error and target localization error at fiducial registration were measured 30 times for each using a phantom made with plastic pelvic bone model (Sawbones, USA). Sixteen 6.5 mm cannulated screws were inserted into four plastic bone models, and the accuracy was evaluated.
RESULTS
The target localization error was 1.46+/-0.47 mm while the registration error was 0.73+/-0.23 mm. All of the 16 screws were inserted well across the sacro-iliac joint, and there was neither cortical breach nor collision between screws or washers.
CONCLUSION
The accuracy of the developed system was similar to that of optical tracker-based navigation systems, and its helpfulness and usefulness was proven with simulation surgery using plastic bone models.

Development of a Computer-assisted Surgery System for Screw Fixation of the Sacro-iliac Joint: Jin Sup Yeom, Won Sik Choy, Ha Yong Kim, Whoan Jeang Kim, Jong Won Kang, Yeongho Kim, Hyungmin Kim, Donghyun Seo, Seok Lee, Jae Bum Lee, Namkug Kim, Cheol Young Kim; J Korean Soc Fract 2003;16(1):1-7. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.1

Abstract PDF: PURPOSE
The purposes of this study were to develop a computer-assisted surgery system for percutaneous screw fixation of the sacro-iliac joint and to evaluate its accuracy.
MATERIALS AND METHODS
We have developed a navigation system composed of an optical tracking device (Polaris, Northern Digital, Canada) and a personal computer. The registration error and target localization error at hybrid registration were measured using a phantom. The errors were measured 30 times for each. Sixteen 6.5 mm cannulated screws were inserted into four plastic bone models (Sawbones, USA), and the accuracy was evaluated.
RESULTS
The registration error was 0.76 +/-0.33 mm, and the target localization error was 1.43 +/-0.42 mm. All of the 16 screws were inserted well across the sacro-iliac joint, and there was neither penetration of the cortical bones nor collision between screws or washers.
CONCLUSION
The accuracy of the developed system was similar to existing ones, and its usefulness and helpfulness was proven with screw insertion into plastic bone models.

Knee Pain Analysis After Tibia Intramedullary Nailing: Kwang Won Lee, Jong Won Kang, Seung Hun Lee, Ha Yong Kim, Won Sik Choy; J Korean Soc Fract 2001;14(2):278-284. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.278

PURPOSE
To analyze the incidence and clinical and radiological results of anterior knee pain following tibial intramedullary nailing.
MATERIALS AND METHODS
From January 1995 to April 1999, we retrospectively analyzed in 122 patients with tibial fracture who were treated by closed intramedullary nailing. All of 125 cases analyzed the age and sex distribution, mechanism of injury, fracture morphology, relationship of nail position on radiographs to knee pain and relationship of knee pain to the incision methods of patella tendon. Anterior knee pain was assessed with a 10-point analogue scale. Statistical analysis was performed using paired T-test.
RESULTS
At a mean follow-up period of thirty-eight months(12-64 months), sixtynine( 56%) patients(70 of 125 knees) had developed anterior knee pain. Insertion of the nail through the patella tendon splitting incision was associated with a higher incidence of knee pain compared to the paratendon site of nail insertion(62% and 35% respectively). According to the radiological analysis, the mean extent of nail protrusion of 122 patients was -1.4mm and the average nail protrusion of 69 patients with knee pain was 1.3mm respectively. Nail removal resolved or improved the symptoms in 69%.
CONCLUSION
Based on these data, we would recommend a parapatella tendon incision for nail insertion, and nail removal for those patients with a painful knee after bony union.
