dontoid fractures have been treated either conservatively or by surgical fixation, and whether one method is better than the other is still controversial. Because it more effectively overcomes the problems of fracture instability and nonuinon, operative stabilization is now favored over external immobilization for the treatment of Type IIodontoid fractures. Most surgical stabilizations of such fractures use posterior cervical wiring techniques with C1-C2 arthrodesis; these, however, obliterate the rotation and flexion/extension of the atlantoaxial complex,and in Type II-P fractures, provide little resistance to further posterior subluxation. As no arthrodesis is performed, direct anterior screw fixation of odontoid fractures theoretically stabilizes the atlantoaxial complex and preserves its motion. Between January 1993 and December 1996, we performed eleven anterior screw fixations in patients who had suffered odontoid fractures(Type II, III); these were postoperatively followed up for an average of 27 months. Excepet for two cases of permissible malunion, thought to be due to fixation on a partially reduced state, all eleven cases showed firm union at the fracture site, with no significant disabilities and complications. The results indicate that in odontoid fracture reduction and eventual fracture union, the outcome of anterior screw fixation is excellent; there is, in addition, no decrease in cervical motion, a disadvantage inherent in currently accepted methods of treatment.

Cervicothoracic junction instability should be stabilized with the circumferential fusion. In addition, cervicothoracic junctional area should be examined carefully in acute traumatic injury not only to confirm hidden lesions but also to make the proper surgical plans. Here, three patients who underwent cervicothoracic arthrodesis at our institution are presented with a review of literature.

Congenital vertical talus associating tarsal coalition, which is a very anomalous condition and causes severe rigid flat foot, is presented with literary reviews. This case was treated with soft tissue release and triple arthrodesis.

The best treatment option in ankle arthritis have always been debated. It is either ankle arthroplasty or arthrodesis. The incidence of ankle arthritishas increased over the recent decades due to the increasing life span of the population and incidence of injuries sustained during sporting events. Although arthrodesis is still largely regarded as the gold standard for it is a safe procedure but in long term, several studies have reported complications such as arthritis in adjacent joints, hip dysfunction and knee problems. Currently results have shown that ankle arthroplasty offers a better long term results than arthrodesis especially in view of patient’s satisfaction and its good functional outcome. This review article aims to analyse both options and their respective outcomes.

PURPOSE: We analyse and report the result of transfibular ankle arthrodesis using lateral malleolar saving procedureversus lateral malleolar sacrificing procedure. MATERIALS AND METHODS: Eighteen cases of transfibular ankle arthrodesis which were performed since 2001 were included. We devided them into lateral malleolar saving and lateral malleolar sacrificing groups. We reattached and fixed lateral malleolus in 10 cases and sacrificed malleolus for morcelized bone graft in 8 cases. We evaluated clinical results by AOFAS ankle-hindfoot score, visual analogue scale (VAS) and radiological results by union time. Complications and subjective satisfaction degrees were also recorded and compared between two groups. RESULTS: Preoperative mean AOFAS score was 32 points (16~41) and VAS was 7.5 points (7~8) and they were changed into 68.6 points (61~77) and 2.8 points (2~4) postoperatively. There was no significant difference in clinical results between the two groups even though lateral malleolar saving group showed higher AOFAS score (69.4) than lateral malleolar sacrificing group (67.7). Duration of getting union was 11.3 weeks in lateral malleolar saving group and 10.6 weeks in lateral malleolar sacrificing group. There was no difference in subjective satisfaction level. There were one delayed union and one nonunion in lateral malleolar sacrificing group and one nonunion in lateral malleolar saving group. CONCLUSION: There was no difference in clinical and radiological results between lateral malleolar saving group and lateral malleolar sacrificing group of transfibular ankle arthrodesis. Therefore it may not necessary to sacrifice lateral malleolus for bone graft except very selective case for which heavy graft is needed.

If one can measure the actual angle of the bowing and rotation of a long bone three-dimensionally, it will be a great help in fracture reductions, operative treatments of the congenital snomalies, determination of the fusion angles in arthrodeses, and so on. We developed a computer program that gives us the actual bowing and rotation angle when we input the angles from the two X-ray films with known angle between them. We measured anteversion and neck-shaft angle of the femur, the amount of bowing and rotation in fracture model, and the fusion angles in arthrodeses. The angles calculated from the computer program were same as those from another X-ray that showed the actual angle taken by derotating the subject.

Dislocation involving tarsal navicular is a extremely rare injury compare to dislocation of other tarsal bone. One case of the tarsal navicular dislocation associated with subluxation of the midtarsal joint treated by open reduction and arthrodesis was reported.
