RESUMO
OBJECTIVE: To investigate the preliminary clinical effect of closed reduction and cannulated nail internal fixation for femoral neck fracture assisted by robot navigation and positioning system. METHODS: From July 2019 to January 2020, 16 cases of femoral neck fracture ï¼navigation groupï¼ were treated with closed reduction and internal fixation guided by robot system, including 7 males and 9 females, aged 25 to 72 years old with an average of ï¼53.61±5.45ï¼ years oldï¼Garden classification of fractureï¼3 cases of typeâ , 3 cases of typeâ ¡, 8 cases of type â ¢, 2 cases of type â £. Non navigation group ï¼control groupï¼ï¼20 cases of femoral neck fracture were treated with closed reduction and hollow nail internal fixation, 8 males and 12 females, aged 46 to 70 years old with an average of ï¼55.23±4.64ï¼ years oldï¼Garden typeâ in 2 cases, typeâ ¡in 4 cases, type â ¢ in 11 cases, type â £ in 3 cases. The operation time, fluoroscopy times, guide needle drilling times, screw adjustment times, intraoperative bleeding volume and other indicators of two groups were evaluated. RESULTS: Both groups were followed up for 12 to 18 months with an average of ï¼15.6±2.8ï¼ months. The fractures of both groups were healed without delayed union and nonunion. There was no significant difference in healing time between two groupsï¼P=0.782ï¼. There was no significant difference in Harris scores between two groups at the last follow-upï¼P=0.813ï¼. There was no significant difference in operation time between two groupsï¼P>0.05ï¼. There were significant differences between two groups in fluoroscopy times, guide needle drilling times, hollow screw replacement times, and intraoperative bleeding volumeï¼P<0.05ï¼. CONCLUSION: Closed reduction and hollow screw internal fixation assisted by robot navigation system for femoral neck fracture has the advantages of minimally invasive operation, precise screw placement, and reduction of X-ray radiation damage during operation.

OBJECTIVE: To investigate clinical effect of minimally invasive osteotomy and external fixation with the center of roration of angulation (CORA) in treating cubitus varus in adolescents. METHODS: From August 2013 to August 2017, 15 patients with cubitus varus caused by supracondylar fracture of humerus were treated with minimally invasive osteotomy and external fixation with the CORA. Among them, including 9 males and 6 females; 11 patients on the left side and 4 patients on the right side; aged from 13 to 16 years old with an average of 14.5 years old. The time from injury to operation was for 6 to 10 years with an average of 7.5 years. Five patients had a history of recurrence after cubitus varus surgery. Correction time. fracture healing time, carrying angle were observed, Laupattarakasem standard was used to evaluate clinical effect. RESULTS: All patients were followed up from 12 to 30 months with an average of 24 months; correction time ranged from 3 to 5 weeks with an average of 4 weeks; fracture healing time ranged from 4 to 6 months with an average of 5 months; carrying angle before operation ranged from -12° to -23°, and improved 9° to 14° after operation. According to Laupattarakasem evaluation criteria, 11 patients got an excellent result, 3 good and 1 fair. CONCLUSIONS: Minimally invasive osteotomy and external fixation with CORA in treating cubitus varus deformity in adolescents has advantages of less trauma, less blood loss, earlier exercise, speed and angle of correction could controlled without hospitalized for fixation.
