Proximal femur fractures (PFFs), including both intracapsular (femoral neck fractures) and extracapsular fractures (intertrochanteric femoral fractures, IFFs), affect around 1.5 million people per year worldwide. Mechanical failures of intertrochanteric nailing in IFFs could be managed with revision total hip arthroplasty (THA).
To assess if the conversion of failed nailing to THA in patients with previous PFFs has a high perioperative complication rate.
To describe the surgical complexity and the procedure-related complication rates, in patients referring with trochanteric nailing failure and treated with THA
Patients referred to our level I trauma center between April 2012 and July 2018 with failed cephalomedullary nailing following trochanteric fractures were retrospectively recruited. All patients underwent a salvage surgical procedure, i.e., cephalomedullary nail removal and conversion to THA. The surgical procedures were performed by the same surgical and anesthesiology team under spinal anesthesia. All patients underwent clinical and radiographic follow-ups for a minimum of 24 mo. Complications and re-operations were recorded.
Seventy-four patients met the inclusion criteria (male: 29; female: 45; mean age: 73.8-years-old; range: 65-89) and were included in the current study. The average operative time was 117 min (76-192 min). The average blood loss was 585 mL (430-1720 mL). Of the 74 patients, 43 patients (58.1%) required transfusion of three or more blood units. Two patients died within the 4th d after surgery because of pulmonary embolism. One patient died 9 mo after surgery due to ischemic myocardial infarction. The complication rate in the 71 patients who completed the minimum 24-mo follow-up was 22.50%. In 3 cases (4.23%) periprosthetic acetabular fracture was observed during the follow-up. One of these periacetabular fractures occurred intraoperatively. An intraoperative periprosthetic femur fracture was observed in 5 patients (7.00%). Four of these patients needed a re-operation to fix the fracture with plates and cerclages; in one of these patients, femoral stem revision was also necessary. In 4 patients (5.60%) an early THA dislocation was observed, whereas in 1 patient (1.40%) a late THA dislocation was observed. Three patients (4.23%) developed a periprosthetic joint infection during the study follow-up.
The present study demonstrated that salvage options for IFF fixation failure are complex procedures with a relevant intraoperative and postoperative complication rate.
Based on the present study findings, it is mandatory to adequately plan the surgical treatment in patients with PFFs since a revision surgery has a risk of high rates of perioperative local and systemic complications.
