We implemented an exhaustive operative and supervision algorithm for surgical treatment of hip fractures primarily based on own previously published literature. The purpose was to improve supervision and reduce the rate of reoperations. 2000 consecutive unselected patients above 50 years admitted with a hip fracture were included, 1000 of these prospectively after implementation of the algorithm. Demographic parameters, hospital treatment and reoperations within the first postoperative year were assessed from patient records. The algorithm dictated the surgical treatment based on three objective patient parameters: age, new mobility score and fracture classification on pre-operative anterior-posterior and axial radiographs. Intra capsular fractures were treated with two parallel implants, a sliding hip screw, an arthroplasty or resection of the femoral head. Extra capsular fractures were treated with a sliding hip screw or an intramedullary nail. Supervision of junior registrars was mandatory for the prosthesis and intramedullary nail procedures.Introduction
Materials and methods
During the operative procedure, the lateral femoral wall was fractured in 6% (9/158) of patients, in which an IMHS was performed versus 28% (42/153) operated with a DHS (p<
0.001). Among the DHS, a fractured lateral femoral wall was confirmed to be a predictor of a reoperation (31% (13/42) of patients with a fractured lateral femoral wall versus 8% (9/111) with an intact lateral femoral wall, p<
0.001). As in other studies, the different reoperation rate would have been overseen in the main group of AO/ OTA type 31A1-2 PTF fractures (4% (6/164) IMHS versus 6% (30/471) DHS, p=0.196).
After implementing the guideline, the rate of unsupervised junior registrars performing operations declined from 20% (188/938) to 6% (21/336, p<
0.001 X2). The rate of reoperations declined from 15% (139/938) to 10% (35/336, p=0.044 X2, p=0.043 log.reg.), with a 20% (85/436) to 13% (23/174) decline for intracapsulary and an 11% (54/502) to 7% (12/162) decline for extracapsulary fractures.
