Abstract

Introduction

The management of hip fractures has advanced on all aspects from prevention, specialised hip fracture units, early operative intervention and rehabilitation in line with increasing incidence in an aging population. Accurate data analysis on the incidence and trends of hip fractures is imperative to guide future management planning.

Methods

A review of all articles published on mortality after hip fracture over a twenty year period (1999–2018) was undertaken to determine any changes that had occurred in the demographics and mortality over this period. This article complements and expands upon the findings of a previous article by the authors assessing a four decade period (1959 – 1998) and attempts to present trends and geographical variations over sixty years.

Abstract

Background

Dislocation of a hip hemiarthroplasty is a devastating complication with a high mortality rate in elderly patients. Previous studies have suggested a higher dislocation rate in patients with neuromuscular conditions. In this study, we have reviewed our larger cohort of patients to identify whether there is any association between neuromuscular disorders and prosthetic dislocation in patients treated with hip hemiarthroplasty for femoral neck fractures.

Patients and Methods

Our study is a retrospective analysis of data collected over 34 years for patients with intracapsular neck of femur fracture who underwent hip hemiarthroplasty. The study population is composed of four groups: patients with no neuromuscular disorders, patients with Parkinson's disease, patients with previous stroke, and patients with dementia.

Introduction

When treating a patient admitted with hip fracture it is useful to have a simple scoring system to predict outcomes, based on admission clerking and routine investigations. The Nottingham Hip Fracture Score (NHFS) is one such measure. Its use has been described by Wiles et al (Br J. Anaes. Jan. 2001) for risk stratification in predicting 30-day and 1-year mortality.

Objective

Our aim was to use the hip fracture database at Peterborough City Hospital, UK to conduct an independent validation study of the NHFS stratification system.

Introduction

The incidence of distal femoral fractures amongst elderly patients is likely to rise due to increased life expectancy. This study reports on the outcome of a series of distal femoral fractures treated by retrograde femoral nailing and then to compare the results for these patients with a series of patients with a proximal femoral fracture.

Materials and/Methods

In this longitudinal cohort study, 36 patients with extra-articular distal femoral fractures were treated with a solid retrograde femoral nail. Data was collected prospectively and then compared to proximal femoral fractures (2426) treated by the same surgeon treated over the same time period.

The purpose of the study was to identify factors that affect the incidence of deep wound infection after hip fracture surgery.

Data from a hip fracture database of 7057 consecutively treated patients at a single centre was used to determine the relationship between deep wound sepsis and a number of factors. Fisher's exact test and the unpaired T test were used. All patients were initially followed up in a specialist clinic. In addition a phone call assessment was made at one year from injury to check that no later wound healing complications had occurred.

There were 50 cases of deep infection (rate of 0.7%). There was no significant difference in the rate of deep sepsis with regards to the age, sex, pre-operative residential status, mobility or mental test score of the patient. Specialist hip surgeons and Consultants have a lower infection rate compared with surgeons below Consultant grade, p=0.01. The mean length of anaesthesia was longer in the sepsis group (76minutes) compared to the no sepsis group (65minutes), this was significant, p=0.01. The patient's ASA grade and fracture type were not significant factors. The rate of infection in intracapsular fractures treated by hemiarthroplasty was significantly greater than those that had internal fixation, p=0.001. The rate of infection in extracapsular fractures fixed with an extra-medullary device was significantly greater than those fixed with an intra-medullary device, p=0.021. The presence of an infected ulcer on the same leg as the fracture was not associated with a higher rate of deep infection. In conclusion we have found that the experience (seniority) of the surgeon, the length of anaesthesia and the type of fixation used are all significant factors in the development of deep sepsis. These are all potentially modifiable risk factors and should be considered in the treatment of hip fracture patients.

Hip fractures are common injuries in the elderly, with significant mortality and morbidity from several factors. Many of these patients have cardiac disease, and some develop cardiac complications which may increase mortality.

Troponin T is a marker of myocardial injury but can be raised in other conditions. Patients over 60 years old admitted with hip fracture during the study period had their troponin T measured on admission and following surgery. Assay was performed after the patient had completed their treatment. We report the results of this study one year after the last patient was admitted.

108 patients were recruited. The average age was 84 years; 86% were female. This study found that 27% of hip fracture patients had some increase in the troponin T levels in the peri-operative period. This increase was not associated with an increase in early mortality, but there was an increase in one-year mortality for those with an increase in troponin T (45% versus 22%, p=0.03). These findings indicate that the routine measurement of troponin T after a hip fracture is unnecessary.

In order to define the optimum timing of surgery for a hip fracture, we undertook a systematic review of all previously published studies on this topic. Data from the retrieved studies were extracted by two independent reviews and the methodology of each study assessed. In total, 43 studies involving 265,137 patients were identified. Outcomes considered were mortality, post-operative complications, length of hospital stay and return of patients back home.

There were no randomised trials on this topic. Six studies of 8535 patients have the most appropriate methodology, which was prospective collection of data with adjustment for confounding variables. These studies found no effect on mortality for any delays in surgery. One of these studies found fewer complications for those operated on early but this was not found in the other study to report on these outcomes. Two of these studies reported on hospital stay, which was reduced for those operated on early. Six studies of 229,418 patients were retrospective reviews of patient administration databases with an attempt at adjusting for confounding factors. They reported a reduced mortality, hospital stay and complications for those operated on early. Thirty-one other studies of variable methodology reported similar findings of reduced complications with early surgery, apart from one study of 399 patients which reported an increased mortality and morbidity for those operated on within 24 hours of admission.

In conclusion those studies with more careful methodology were less likely to report a beneficial effect of early surgery, particularly in relation to mortality. But early surgery (within 48 hours of admission) does seem to reduce complications such as pressure sores and reduces hospital stay.

1133 patients with an intracapsular fracture of femoral neck treated by internal fixation were prospectively studied. All surviving patients were followed up for a minimum of one year from injury. The overall incidence of non-union was 229 (20.2%) and the incidence of avascular necrosis was 61 (5.4%). Fracture non-union was less common for undisplaced fracture in comparison to displaced fractures (48 out of 565 (8.5%) versus 181 out of 568 (31.9%)) and in males than females (45 out of 271 (16.6%) versus 184 out of 862 (21.3%)). The incidence of non-union progressively increased with age from one out of 17 (5.9%) in those aged below 40 years to 84 out of 337 (24.9%) in those in their seventies. For those in their eighties the incidence of non-union began to fall, but if those patients who died within one year from injury were excluded, then the incidence was found to continue to increase. For avascular necrosis there was a falling incidence with age from 9 out of 68 (13.2%) in those aged less than 50 years to 10 out of 388 (2.6%) in those aged over 80 years.

The information from this large series of patients treated by contemporary methods enables the surgeon to use the three factors of age, sex and presence of fracture displacement to predict the risk of non-union or avascular necrosis occurring.

The two commonest types of hemiarthroplasty used for the treatment of a displaced intracapsular fracture are the uncemented Austin Moore Prosthesis and cemented Thompson hemiarthroplasty. To determine if any difference in outcome exists between these implants we undertook a prospective randomised controlled trial of 300 patients with a displaced intracapsular hip fractures.

All operations were performed or supervised by one orthopaedic surgeon and all by a standard anterolateral approach. Patients were followed by a nurse blinded in the type of prosthesis to assess residual pain and mobility.

The average age of the patients was 83 years and 23% were male. 73% came from their own home with the remainder from institutional care. There was no statistically significant difference in mortality between groups, with 34/151 having died at one year in the cemented group and 45/149 in the uncemented group. Pain scores (grade 1-6) were less for those treated by a cemented prosthesis (mean score 1.8 versus 2.4, p value <0.00001). Mobility change was also less for those treated with a cemented implant (p=0002). No difference was found in hospital stay. Operative complications are as listed. One case of non-fatal intraoperative cardiac arrest occurred in the cemented group.

In summary a cemented Thompson Hemiarthroplasty causes less pain and less deterioration in mobility compared to uncemented Austin Moore hemiarthroplasty, without any increase in complications. The continued use of an uncemented Austin Moore cannot be recommended.
