ABSTRACT
Nine scaphoid non-unions, which were treated by through curettage of the scar tissue on pseudarthrosis, iliac bone grafts between the fragments and Herbert screws fixation, were analysed. The average follow up period from operation was 16.9 months. The interval between the fracture and the time of the operation ranged from 10 months to 48 months(average 21.6 months). Average union time was 14 weeks after operation. The initial radiologic cystic changes disappeared and overall clinical results were improved. Mean postoperative range of motion of the wrist was flexion 55 and extension 45°. Three of them had DISI deformity preoperatively which their scapholunate angles (mean 104°) has been corrected after reduction (mean 75°). In one case among three DISI deformities, partial radial styloidectomy and triscaphe fusion were added (to bone graft and Herbert screw fixation). A case of incorrect positioning of the screw and a case of neuroma were complicated. Treatment of scaphoid nonunion with curettage of the scar tissue and iliac bone graft and Herbert screw fixation seems to be encouraging to regain the normal anatomy of scaphoid and function of the wrist.

Seventy four consecutive cementless Tricon-M total knee replacement were followed for two to eight years (average three and half years) at the Department of Orthopedics Kangnam St. Mary's Hospital Catholic University Medical College. Using the Hospital for Sepcial Surgery rating system we found that 86.6 percent of the knee were graded excellent or good, 8 percent fair and 5.4 percent poor. In four cases of complication, two patients had gram negative infection postoperatively and one had one stage revision using gentamycine mixed cement and the other who had delayed infection one year after surgery had arthroscopic irrigation and synovectomy. Other two complications were patella lateral sublugation but the realignment operation had been refused. In radiologic examination there were no radiolucenct loosening sign in any patella or femoral component but tibial radiolucency was seen in only three patients. Thirty four (46%) out of 74, cases showed tibial component subsidency (average 2.2mm) during the first one year follow up period but no further progression was seen in later follow up period. No correlation.between radiolucency or subsidence and knee scores was seen. Cementless fixation of all components in total knee replacement, including the tibia and patella, was highly successful and can be achieved without stress relief of the distal femur.
