ABSTRACT
Objective To evaluate Kangli hollow screws with sliding compression locking plate system (KHS) in the treatment of femoral neck fractures.Methods From February 2015 to October 2016,47 femoral neck fractures were treated at Department of Orthopaedics,Wuhan Fourth Hospital,Wuhan Puai Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology.They were 30 men and 17 women,aged from 26 to 68 years (average,43.5 years).According to the Pauwels classification,there were 24 cases of type Ⅰ,16 cases of type Ⅱ and 7 cases of type Ⅲ;according to the Garden classification,there were 23 cases of type Ⅱ,19 cases of type Ⅲ and 5 cases of type Ⅳ.All the fractures were immobilized with KHS after closed reduction or open reduction (3 cases).The fracture union time,femoral head necrosis and femoral neck shortening were observed after operation.The Harris scores were used to evaluate therapeutic effects at the final follow-up.Results All the patients were followed up for an average of 29.7 months (from 22 to 39 months).All the fractures obtained solid bony union after 9 to 15 weeks (average,12.2 weeks).Femoral head necrosis occurred in one case (2.1％).Femoral neck shortening ≤ 5 mm was observed in 6 cases and femoral neck shortening ＞ 5 mm ＜ 10 mm in 2 cases,giving a total shortening rate of 17.0％.The Harris scores at the final follow-up ranged from 77 to 98 points,averaging 92.2 points.There were 42 excellent,3 good and 2 moderate cases,giving an excellent and good rate of 95.7％.Conclusion KHS can lead to excellent therapeutic effects in the treatment of femoral neck fractures.

Objective@#To evaluate Kangli hollow screws with sliding compression locking plate system (KHS) in the treatment of femoral neck fractures.@*Methods@#From February 2015 to October 2016, 47 femoral neck fractures were treated at Department of Orthopaedics, Wuhan Fourth Hospital, Wuhan Puai Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology. They were 30 men and 17 women, aged from 26 to 68 years (average, 43.5 years). According to the Pauwels classification, there were 24 cases of type Ⅰ, 16 cases of type Ⅱ and 7 cases of type Ⅲ; according to the Garden classification, there were 23 cases of type Ⅱ, 19 cases of type Ⅲ and 5 cases of type Ⅳ. All the fractures were immobilized with KHS after closed reduction or open reduction (3 cases). The fracture union time, femoral head necrosis and femoral neck shortening were observed after operation. The Harris scores were used to evaluate therapeutic effects at the final follow-up.@*Results@#All the patients were followed up for an average of 29.7 months (from 22 to 39 months). All the fractures obtained solid bony union after 9 to 15 weeks(average, 12.2 weeks). Femoral head necrosis occurred in one case (2.1%). Femoral neck shortening ≤ 5 mm was observed in 6 cases and femoral neck shortening >5 mm <10 mm in 2 cases, giving a total shortening rate of 17.0%. The Harris scores at the final follow-up ranged from 77 to 98 points, averaging 92.2 points. There were 42 excellent, 3 good and 2 moderate cases, giving an excellent and good rate of 95.7%.@*Conclusion@#KHS can lead to excellent therapeutic effects in the treatment of femoral neck fractures.
ABSTRACT
Objective To evaluate euthyphoria reduction combined with percutaneous iliosacral screw fixation in the treatment of irreducible sacroiliac dislocation.Methods From March 2012 to May 2015,29 patients with irreducible sacroiliac dislocation were treated using euthyphoria reduction followed by percutaneous iliosacral screw fixation.They were 18 men and 11 women,aged from 25 to 68 years (average,37.9 years).According to the Tile classification,there were 7 cases of type Cl,9 cases of type C2,and 13 cases of type C3.The intervals from injury to surgery ranged from 6 to 32 days (average,11.3 days).Results The operation time for this cohort ranged from 40 to 125 minutes (average,76.2 minutes).The intraoperative bleeding ranged from 50 to 360 mL (average,148.6 mL).Their follow-ups ranged from 24 to 41 months (average,28.9 months).According to the Matta criteria for reduction,20 cases were rated as excellent and 9 as good,yielding an excellent to good rate of 100％.Their Majeed scores at the final follow-up averaged 90.1 points (range,from 67 to 100 points),giving 20 excellent,7 good and 2 fair cases (with an excellent to good rate of 93.1％).No screw loosening or lameness of the affected limb was observed during follow-ups.Conclusions Euthyphoria reduction combined with percutaneous iliosacral screw fixation can lead to satisfactory outcomes in the treatment of irreducible sacroiliac dislocation.Additionally it may improve operative safety.
