OBJECTIVE: To evaluate the rate of basicervical fractures and document their diagnosis and treatment. METHODS: From January 2005 to May 2016, 28 basicervical fractures of the 832 trochanteric fractures were collected and evaluated. The patients were treated with multiple screws, dynamic hip screw (DHS), intramedullary nail. Via the operation time, postoperative hospitalization, loss of blood duration the operation, hidden blood loss, total blood loss, mean union time and the final follow-up Harris hip score, the characteristics of different internal fixations were compared and analyzed. RESULTS: The incidence of basicervical fractures was 3.37% (28/832) in our study. In the intramedullary nail group (16 patients), the operation time was 55 (20,120) min, the postoperative hospitalization was 3(2, 7) d, the intraoperative blood loss was 50 (5,100) mL, the hidden blood loss was 533.37 (376.19, 987.15) mL, and the total blood loss 627.35 (406.19, 1037.16) mL. The union time and final follow-up Harris score were 6 (3, 9) months and 90.25 (74,100) min. In the DHS group (8 patients), the operation time was 87.5 (65,115) min, the postoperative hospitalization was 5.5 (2, 17) d, the intraoperative blood loss was 100 (50,300) mL, the hidden blood loss was 278.11 (202.43, 849.97) mL, and the total blood loss 580.19 (368.55, 899.97) mL . The union time and final follow-up Harris score were 5.5 (4, 12) months and 85.5 (84, 87) min. In the multiple screws group (4 patients), the operation time was 47.5 (35, 75) min, the postoperative hospitalization was 5 (2, 12) d, the intraoperative blood loss was 20 (2, 70) mL, the hidden blood loss was 150 (100.00, 412.01) mL, and the total blood loss 195.00 (120.00, 414.01) mL. The union time and final follow-up Harris score were 4 (4, 6) months and 80 (61, 97) min. The patients treated with multiple screws and intramedullary nail had a shorter operation time than the DNS group, but no obvious difference was found between the other two groups (P=0.367). Postoperative hospitalization had no significant difference among the three groups. The intraoperative bleeding was more in the DHS group, the other two groups had no significant difference (P=0.100). However, the hidden blood loss was more in the intramedullary nail group, the other two groups had no significant difference (P=0.134). The total blood loss in the intramedullary nail group was more than multiple screw group, similar to the DHS group (P=0.483). One patient treated with multiple screws underwent internal fixation failure three months after operation. The mean union time and final follow-up Harris scores had no significant difference among the three groups (P>0.05). CONCLUSION: Through this study, we found that the incidence of basicervical fractures is low. Fractures with no shift can be confirmed by preoperative X-ray. For displaced fractures, preoperative CT+3D reconstruction is recommended. Surgical treatment by closed reduction and internal fixation with DHS or intramedullary nail is shown to be very effective.
