Purpose; Delayed presentation of lateral condylar fractures of the humerus is relatively common in the developing regions of the world. These fractures are difficult to manage because of the displacement and fibrosis around the condylar fragment secondary to the delay. There is a paucity of literature concerning the management of these fractures. An oft repeated finding is the requirement of extensive dissection around the fragment for proper reduction. The purpose of this study was to assess the efficacy of surgical management of lateral condylar fractures with delayed presentation. Methods; We assessed the results of lateral condylar fracture fixation in 20 cases with delayed presentation. Results; The lateral condylar fractures in patients with a delayed presentation can be managed surgically with good results. Conclusions; Open reduction and internal fixation should continue to be the method of choice for the management of lateral condylar fractures which report late for management.

The clinical failure factors of Orthopedic implants which happened recent years have been summarized. The main failure factors are quality of orthopedic implants itself, iatrogenic and patient-derived. The ways to preventive measures have been suggested.

BACKGROUND: Major orthopedic surgical procedures, including spinal fusions, require 2 or 3 units of transfusion. In this study, we evaluated the usefulness of autologous transfusion by comparing the postoperative infections, the pre- and postoperative serological changes, the amount of transfusion during the operation and the segmented estimated blood loss of the patients who received spinal fusion surgery. METHODS: We analyzed 106 patients who were undergoing spinal fusion surgery and among them, 69 patients were operated on with using autologous transfusion, while 37 cases were operated on with using homologous transfusion. RESULTS: The segmental estimated blood loss was approximately 574.4+/-131.8 mL in group 1 and 635.3+/-250.1 mL in group 2. The mean number of transfused units in the autologous transfusion group was 2.1+/-0.3 units and this was 3.5+/-0.6 units in the homologous transfusion group. There was no significant statistical difference in the hemoglobin level or the complications between the two groups, yet the duration of fever in the group with homologous transfusion was 3.0+/-0.4 days, which was increased compared to that of group 1 (1.4+/-1.3 days). CONCLUSION: The total amount of transfusion and blood loss for the patients who were operated on using autologous transfusion were less, as compared to those for the patients who were operated on with homologous transfusion, and the patients with homologous transfusion showed a significantly decreased duration of fever. It seems that autologous transfusion is a way to shorten the duration of fever and increase the satisfaction of the patients.

A great deal of comparisons on domestic standards for Orthopedic implants with ISO and ASTM standards have been presented, and some conclusions have been drawn: Domestic standards for orthopedic implants coincide with ISO and ASTM standards in the items of materials, geometry and classification. There are much bigger differences in some key performances of implants such as assembly, fatigue, wear and tear and so on. Some constructive ways have been suggested.

The purpose of this study was to provide quantitative data describing the effect of rapid palatal expansion (RPE) on nasal airway resistance (NAR). RPE is an orthopedic procedure which is commonly used to widen the maxilla in skeletal Class III patients. 18 subjects (9 males and 9 females, mean age: 10 years 7 months) were selected from the Orthodontics in Yongdong Severance Hospital. Recordings of NAR were taken by active anterior method prior to expansion, immediately after desired maximum expansion, and after approximately 3 months and 6 months, and 1 year. All data was recorded and statistically processed with the SPSS program of IBM PC system. The results are as followings: 1. The average initial NAR of the subjects was 3.84cm H2O/LPS (SD +/- 1.34). It was greater than the average NAR of the normal subjects. 2. Among 18 subjects, 9 subjects showed reduction of NAR and 9 subjects showed no specific change of NAR after expansion. 3. An average reduction in NAR after immediately expansion was statistically significant at the 0.05 level. 4. The reduction appeared stable throughout the post treatment observation period of 1 year after expansion. From these results, it was suggested that RPE is a useful method to reduce NAR.
