Mortality in patients sustaining a periprosthetic fracture following a previous extracapsular hip fracture fixation
1Department of Trauma and Orthopaedics, Plymouth Hospitals NHS Trust, Derriford Rd., Crownhill, Plymouth, PL6 8DH, United Kingdom.
Background:
Mortality rates following hip fractures are decreasing. As these outcomes improve, it increases the potential for further falls and the potential to sustain a periprosthetic fracture. The aim of this study was to analyse the 1 year mortality of periprosthetic fractures around an implant used to treat an extracapsular hip fracture. Secondary outcomes included 30 day mortality, complications and risk factors associated with mortality.
Methods:
A retrospective case note and radiographic review of all patients who presented to a single institution with a periprosthetic femoral fracture around an implant previously used to treat an extracapsular hip fracture between 1st January and 2008 and 31st May 2015.
Results:
29 patients with a mean age of 75.8. 6 males and 23 females. 20 (69.0%) patients had capacity to consent for surgery. Pre-operatively 34.5% mobilised independently without any walking aids. 79.3% lived at home. 62.1% had a Charlson co-morbidity score of 0 or 1, 27.6% a score of 2 or 3, 6.9% a score of 4 and 5, and 3.4% a score of more than 5.3.4% was ASA grade 1, 13.8% ASA2, 65.5% ASA 3 and 17.2% were ASA 4. The previous implant a dynamic hip screw in 75.9% dynamic hip screws and an intramedullary nail in 24.1%. There were 4 (13.8%) in-patient deaths. The 30 day mortality 17.2% (5 patients) was and the 1 year mortality was 44.8% (13 patients). There were 0 complications that required return to surgery during admission. 1 patient with a revision intramedullary nail had dynamisation performed due to delayed union 7 months following surgery. 1 patient required removal of metalwork 2 years following surgery for infection. When comparing risk factors for mortality, there were no significant risk factors found in this study for 30 day and 1 year mortality.
Conclusions:
This paper suggests that periprosthetic fractures sustained after the surgical treatment of extra capsular neck of femur fractures have higher mortality rates than hip fractures. These patients should be given the same priority as these patients in there management.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
