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.
