Objectives

The purpose of this study was to develop an accurate, reliable and easily applicable method for determining the anatomical location of the joint line during revision knee arthroplasty.

Aims: We aimed to evaluate diagnostic contribution of MRI-Arthrography in syndesmosis disruption at ankle fractures. Methods: 18 patient who had Denis Weber type B-C fractures and are suspected to have syndesmotic diastasis considering tibiofibular clear space and tibiofibular overlap measurments in conventional radiographs are assesed with MRI followed by MRI-Arthrography. Because joint fluid was already seen in tibiofibular space in 3 patients at MRI, MRI-Arthrography was performed for the remaining 15 patients. If there was a changes between the results obtained from MRI and the results obtained after MRI-arthrography was tested istatistically. Convantional radiographs, MRIs and MRI-Arthrographies were analysed by 2 independent observers and interobserver concordance was assesed. Following intraoperative observation and asssesment syndesmotic diastasis was treated considering radiographic and MRI-arthrographic results. Results: In 15 cases who were regarded to have syndesmotic diastasis according to conventional radiographies, 8 (53.3%) diastasis were confirmed with only MRI and 12 (80%) diastasis were confirmed with MRI arthrography. Following intraoperative assesment 13 (86.6%) cases were regarded to have diastasis and surgical intervention was performed for diastasis repair. In 2 (13.3%) cases surgical intervention for diastasis repair was not performed. If there was a change in decission after MRI and after MRI-arthrography is analysed with chi-square test between related groups. There were statistically significiant difference (p< 0.05) in these means. There is interobserver concordance in conventional radiographic, MRI-arthrographic assesments and in assesments for ATIF and PTIF seperately inMRI.(p< 0.001). Conclusion: These results suggest that conventional radiography and MRI is not sufficient in assesing syndesmosis and MRI-arthrography is important for diagnosis.

We treated 22 children with a supracondylar fracture of the humerus and an ipsilateral fracture of the forearm by closed reduction and percutaneous fixation. There were four Gartland type-II and 18 Gartland type-III supracondylar fractures of the humerus. There were fractures of both bones of the forearm in 16 and of the radius in six. Both the supracondylar and the distal forearm fractures were treated by closed reduction and percutaneous fixation. The mean follow-up time was 38.6 months.

At the latest follow-up there were 21 excellent or good results and one fair result. There were no cases of delayed union, nonunion or malunion. Five nerve injuries were diagnosed on admission and all recovered spontaneously within eight weeks. No patient developed a compartment syndrome.
