Intramedullary Fixation of Trochanteric Fractures Can Be Safely Performed by Senior Residents Without Immediate Consultant Supervision.

OBJECTIVE

To assess the safety of senior residents performing trochanteric hip fracture surgery without immediate consultant supervision

DESIGN

A retrospective chart review of trochanteric hip fractures (AO-OTA 31-A) operated in a single center between years 2011 and 2016 (inclusive). Operations were divided into three groups: Group 1 - surgeon was a senior resident without any immediate supervision; Group 2 - surgeon was a consultant and Group 3 - surgeon was a senior resident supervised by a consultant. The follow-up period was a minimum of 2 years or until death. All re-operations and surgical related mortality were assessed.

SETTING

Helsinki University Hospital, Finland. A tertiary level trauma center.

PARTICIPANTS

987 consecutive trochanteric fractures on 966 patients treated by operative fixation of an intertrochanteric fracture with an intramedullary nail between 2011and 2016 (inclusive).

RESULTS

The total number of reoperations was smaller in Group 1 where the surgeon was a senior resident without any immediate supervision compared to Group 2 where the surgeon was a consultant (5.5 % vs 8.8 %, p < 0.05). There were no significant differences in mortality or length of surgery. The total rate of mechanical complications was 2.0 %, with no significant differences between groups. The observed blade cut-out rate was low: 1.3 %, suggesting a good overall quality of surgery.

CONCLUSIONS

Senior residents can safely perform intramedullary nailing of trochanteric fractures without immediate supervision.
