Introduction

Debate still exists as to the optimum method of fixation for subtrochanteric femoral fractures. Meta-analysis of studies comparing cephalocondylic nails with extramedullary implants for extracapsular hip fractures have suggested that further investigation is required in this area. We present the outcome of the largest series to date of subtrochanteric fractures treated by both methods and with a minimum of one year follow-up.

Methods

244 patients with a subtrochanteric femur fracture were treated at one centre over a 21 year period were prospectively studied. 75 were treated with an extramedullary fixation implant and 168 with an intramedullary nail. Surviving patients were followed up till one year from injury.

Introduction

There has been little research into the effect of suffering a simultaneous hip and upper limb fragility fracture. The aim of this study is to describe the characteristics of this important group of patients and to define the effect on outcomes such as mortality and length of stay.

Materials and methods

Hip fracture data in our unit is collected prospectively and entered into a database. All study data was taken from this database. Patients under 60 years of age were excluded from the study.

Although it has long been appreciated that a healthy balanced diet improves health, there is a growing understanding of the way in which certain nutrients can actually improve immune function. Boosting immune function by the use of “immunonutrition” has been shown to improve outcomes, in particular rates of infective complications, in certain groups of surgical patients.

In this study we examine the immune status of elderly patients who have suffered a hip fracture and are known to be vulnerable to infection and poor post-operative outcomes to identify specific immune defects associated with this particular cohort. This may allow us to explore the potential benefits of immunonutrition in this group of patients in the future.

This was a cohort observational study, in which a series of 16 patients who underwent surgery for hip fractures were followed. The patients were female patients with an age of 60 to 85 years and a mental status questionnaire score of at least 8 out of 10.

Immune function was evaluated prior to surgery, on the day following surgery and then at between days 4 and 7 post-operatively. Samples were tested directly ex-vivo using a variety of flow cytometric assays.

We report profound loss of innate immune function related specifically to monocyte and granulocyte ability to generate a respiratory burst in response to E.coli uptake persisting up to day 7 post-operatively. In addition, serum cytokine levels indicated very poor T cell function, in identifying these patients as particularly vulnerable to infections.

Prospective data on 6905 consecutive hip fracture patients at a district general hospital were analysed to identify the risk factors for the development of deep infection post-operatively. The main outcome measure was infection beneath the fascia lata.

A total of 50 patients (0.7%) had deep infection. Operations by consultants or a specialist hip fracture surgeon had half the rate of deep infection compared with junior grades (p = 0.01). Increased duration of anaesthesia was significantly associated with deep infection (p = 0.01). The method of fracture fixation was also significant. Intracapsular fractures treated with a hemiarthroplasty had seven times the rate of deep infection compared with those treated by internal fixation (p = 0.001). Extracapsular fractures treated with an extramedullary device had a deep infection rate of 0.78% compared with 0% for those treated with intramedullary devices (p = 0.02).

The management of hip fracture patients by a specialist hip fracture surgeon using appropriate fixation could significantly reduce the rate of deep infection and associated morbidity, along with extended hospitalisation and associated costs.
