Abstract
Objectives
To analyse the costs and benefits of sending femoral head specimens for histopathological analysis and whether our practice had changed since the original study five years ago.
Methods
The cohort definition was patients who had both undergone hip hemiarthroplasties (HHAs) and had femoral head specimens sent for histopathological analysis at our tertiary care institution from 2013 to 2016. Retrospective review of clinical and electronic notes was performed on these patients for history of malignancy, histopathological diagnosis of femoral head, indication for histopathological examination and radiological studies. The total number of HHAs performed at the centre and the costs involved in analysing each femoral head specimen were identified.
Results
A total of 805 HHAs were performed at the centre. We identified 56 femoral head specimens from 56 patients (6.96%) that were sent for histopathological analysis after HHA. 29 patients (51.79%) had a known history of malignancy. Three femoral head specimens (10.34%) were histologically positive for malignancy. Two patients had hip radiographs demonstrating metastasis to the femoral head. The third patient had a PET-CT scan two weeks prior to fracture that did not show signs of metastatic disease. 27 patients (48.21%) had no history of malignancy. None of their femoral head specimens were found to be histologically positive for malignancy. 10 patients had no appropriate indication for histopathological analysis. The cost savings for 27 patients with no previous history of malignancy ranged from €2,295 to €9,504. The cost savings for 10 patients with no appropriate indication ranged from €850 to €3,520.
Conclusions
Histopathological analysis of femoral head specimens after HHA has little benefit for patients without a history of malignancy. The practice at our institution had not changed significantly in the past five years.
