Fifty two cases of displacecd supracondylar fractures were divided into three groups according to the methods of fracture stabilization. Cast immobilizations without pin fixation were included to the group 1 (12 cases), fixation with lateral pins to the group 2 (22 cases), and lateral and medial cross pins to the group 3 (18 cases). In each group we attempted a radiological analysis for the stabilization failure through measurements of the horizontal rotation and the mediolateral tilting in their preoperative, postoperative and follow-up X-rays. Stabilization failure during the follow-up period was presumpted to be present in those cases that show (1) a development or increase of the horizontal rotation in follow-up lateral X-ray, and (2) accompanied change in Baumann's angle of more than 5 degrees. The failed stabilizations were in three cases (25%) in the group 1. In the group 2 the horizontal rotations after initial fixation were developed in four fractures. However, only two (9%) of the four cases accompanied significant changes in the Baumann's angle. Loss of the initial fixation in the cross pin group was found in one case. These results demonstrate that the cross pin fixation is the most stable form. Fixation in only lateral side sometimes shows rotational instability, but this method seems to be still useful because singificant coronal tilting develops in only a few occasions of those with horizontal rotation.

From retrospective review of 111 tibial fractures treated by interlocking intramedullary nailing, 38 operative errors in 28 cases(25%) were included in this study. The errors were classified into two categories. The first category included eighteen errors that related to fracture reduction; nine angular malalignments, four failures in closed nailing to open the fracture site, two peroneal nerve palsies, two shortenings of tibial length(more than 1cm), and one rotational malalignment. The second category comprised twenty errors that related to the nailing itself; eight protrusions of proximal nail tip, five overdistractions of fracture gap (more than 3mm), four additional fragmentations, two mistakes in interlocking screw insertion, and one ankle joint injury by the distal nail tip. Functional results of those 28 cases at the last follow-up(average, 17.5 months; range, 9 to 29 months) were excellent or good in only 60.8 per cent, while the control group treated by adequate operative technique showed excellent or good results in 92.8 per cent.

PURPOSE: The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior jaws for up to 1 year of function. MATERIAL AND METHODS: Eight patients received 20 implants posterior to canines. Two or more implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading. RESULTS: All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was 0.15 mm higher after 1 year. CONCLUSION: Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive missing teeth may clinically function well in the posterior jaw.
