A consecutive series of 320 patients with an intracapsular fracture of the hip treated with a dynamic locking plate (Targon Femoral Neck (TFN)) were reviewed. All surviving patients were followed for a minimum of two years. During the follow-up period 109 patients died.
There were 112 undisplaced fractures, of which three (2.7%) developed nonunion or re-displacement and five (4.5%) developed avascular necrosis of the femoral head. Revision to an arthroplasty was required for five patients (4.5%). A further six patients (5.4%) had elective removal of the plate and screws.
There were 208 displaced fractures, of which 32 (15.4%) developed nonunion or re-displacement and 23 (11.1%) developed avascular necrosis. A further four patients (1.9%) developed a secondary fracture around the TFN. Revision to a hip replacement was required for 43 patients (20.7%) patients and a further seven (3.3%) had elective removal of the plate and screws.
It is suggested that the stronger distal fixation combined with rotational stability may lead to a reduced incidence of complications related to the healing of the fracture when compared with other contemporary fixation devices but this needs to be confirmed in further studies.
