Aims

Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years.

Methods

Eligible patients at a level I trauma centre were recruited into a longitudinal registry of surgical acetabular fractures between June 2004 and August 2019. Patient-reported outcome measures (PROMs), including the 36-Item Short Form Health Survey (SF-36) physical component summary (PCS), were recorded at baseline pre-injury recall and six months, one year, two years, and five years postoperatively. Comparative analyses were performed for elementary and associated fracture patterns. The proportion of patients achieving minimal clinically important difference (MCID) was determined. The rate of, and time to, conversion to total hip arthroplasty (THA) was also established.

We performed a systematic review of the literature pertaining to the functional outcomes of the surgical management of acetabular fractures. A total of 69 articles met our inclusion criteria, revealing that eight generic outcome instruments were used, along with five specific instruments. The majority of studies reported outcomes using a version of the d’Aubigne and Postel score, which has not been validated for use in acetabular fracture. Few validated outcome measures were reported. No psychometric testing of outcome instruments was performed. The current assessment of outcomes in surgery for acetabular fractures lacks scientific rigour, and does not give reliable outcome data for either scientific comparison or patient counselling.

Take home message: The use of non-validated functional outcome measures is a major limitation of the current literature pertaining to surgical management of acetabular fractures; future studies should use validated outcome measures to ensure the legitimacy of the reported results.

Purpose

The prevention of a subsequent, contralateral hip fracture is targeted as an avoidable event in the elderly. Fall prevention and bone strengthening measures have met with limited success and the urgency of their effect is undetermined. Our objective was to evaluate the time to second hip fracture (the time between a first and a subsequent, contralateral fracture) in elderly patients, using a population-based administrative health data set.

Method

The 58,286 records of persons older than 60 yrs and hospitalized for a hip fracture between 1985 and 2005 were obtained from a Provincial administrative health database. We excluded non-traumatic cases and identified the care episodes related to a subsequent hip fracture for each patient using unique identifiers. We used a 5 year “wash-out period” to avoid counting a second fracture as a first one.

We calculated the proportion of first and second fractures and sex distribution over time (fiscal years) and quantified the time between first and second fracture, while correlating it to age, sex and fracture type.

Purpose

The measurement of functional outcomes in pelvic fracture patients remains difficult for authors. We aimed to test the construct validity, respondent burden, and patient perception of three previously published pelvic outcome questionnaires.

Method

Subjects completed three pelvic specific, and three general functional outcome instruments. Time for each pelvic instrument was recorded, as was which score the patient felt best addressed their symptoms. Patients stated the three most significant impacts the pelvic fracture had on their life.

Purpose

To determine whether there have been changes in the age, sex and subtype specific first hip fracture rates in Canadian province of British Columbia (BC) between 1990 and 2004.

Method

Records of all persons aged 60 years and older hospitalized with hip fractures in BC between 1985 and 2004 were obtained from the Canadian Institute for Health Information Discharge Abstract Database. Only the first hip fracture records were included, and fractures likely due to causes other than trauma were excluded. Age- and sex-specific rates were calculated using population denominators from Statistics Canada and direct standardization was used. Age standardized rates allowed for comparison across years with adjustment for age distribution.

We performed a systematic review of the literature to evaluate the use and interpretation of generic and disease-specific functional outcome instruments in the reporting of outcome after the surgical treatment of disruptions of the pelvic ring. A total of 28 papers met our inclusion criteria, with eight reporting only generic outcome instruments, 13 reporting only pelvis-specific outcome instruments, and six reporting both. The Short-Form 36 (SF-36) was by far the most commonly used generic outcome instrument, used in 12 papers, with widely variable reporting of scores. The pelvis-specific outcome instruments were used in 19 studies; the Majeed score in ten, Iowa pelvic score in six, Hannover pelvic score in two and the Orlando pelvic score in one. Four sets of authors, all testing construct validity based on correlation with the SF-36, performed psychometric testing of three pelvis-specific instruments (Majeed, IPS and Orlando scores). No testing of responsiveness, content validity, criterion validity, internal consistency or reproducibility was performed.

The existing literature in this area is inadequate to inform surgeons or patients in a meaningful way about the functional outcomes of these fractures after fixation.

Purpose: We aimed to determine the effect of delay to surgery in hip fracture patients, including in hospital mortality, major complications, minor complications and length of hospital stay.

Method: We identified 615 eligible patients from the VGH Orthopaedic Trauma database between 1998 and 2002. A thorough chart review was performed. Age, gender, time from admission to surgery, pre-existing medical comorbidity, length of acute care hospital stay, major medical complications, minor medical complications and in hospital death were recorded and categorized. Patients were categorized into three risk groups for pre-existing comorbidity, and three groups for delay to surgery (48 hours). Chi-squared tests were performed to determine the association of delay to surgery to death, major complications, minor complications and length of stay, as a categorical variable. Multivariate logistic regression analysis was used to evaluate these associations, while adjusting for age, gender, and pre-existing medical comorbidity. Anvoa test was used to evaluate the association between length of stay, as a continuous variable, and delay to surgery.

Results There were 471 female patients, and 141 male patients. We identified 52 deaths (8.5%), 72 major complications (11.7%) and 238 minor complications (38.7%). The delay to surgery was < 24 hours in 346 patients (56.3%), 24–48 hours in 216 (35.1%), and > 48 hours in 50 (8.1%). The mean length of hospital stay was 23.4 days. Chi squared test showed no statistically significant association between delay to surgery and in hospital death (p= 0.787), despite a trend to increasing death (< 24 hours 8.1%, 24–48 hours 8.3%, > 48 hours 12.2%). There was no statistically significant association between delay and minor complications. Statistically significant associations between delay to OR and length of hospital stay (p= 0.0026), and the occurrence of a major complication (p=0.0085) were found. Regression analysis of major complications revealed an odds ratio of 1.47 for the > 48 hour group compared to the < 24 hour group, with a confidence interval of 1.15–1.87. Regression analysis did not show a statistically significant odds ratio for either death or minor complications.

Conclusion: There is a trend to increasing mortality and minor complications with a delay to surgery in hip fractures. A statistically significant increase in major medical complications and length of hospital stay with delay to surgery was found in our group. Regression analysis including age, gender and pre-existing medical comorbidity supported the significance of the increased risk of major medical complications with delay, adjusted for age, gender, and pre-existing medical comorbidity.

We describe our early operative experience with a new pelvic reduction frame and the standard of reduction of fractures of the pelvic ring which we achieved in the first 35 consecutive patients, with 34 acute fractures and one nonunion. The pre-operative and immediate post-operative radiographs were measured, using two methods, to find the maximum radiological displacement of the fracture and the quality of the reduction according to the criteria of Tornetta and Matta.

There were 19 vertical shear fractures and 16 compression injuries. The mean age of the patients was 33.5 years (10 to 59) and mean delay to surgery was 4.6 days (0 to 16) in the 34 acute injuries. The mean operative time in isolated procedures was 103.4 minutes (sd 6.5). All but one patient had iliosacral screws implanted, 18 had screws in the anterior column, six had plates at the symphysis pubis and 12 had anterior external fixators. The mean maximum horizontal or vertical displacement was improved from 30.8 mm (sd 2.7) to a mean of 7.1 mm (sd 0.7). The reduction was assessed as excellent in ten patients, good in 18, and fair in the remainder. There was no significant influence on the quality of the reduction caused by obesity (p = 0.34), the type of fracture (p = 0.41) or delay to surgery (p = 0.83).

The frame was shown to be effective, allowing the surgeon to obtain a satisfactory reduction and fixation of acute displaced disruptions of the pelvic ring.

Our aim was to determine the effect of delay to surgery on the time to discharge, in-hospital death, the presence of major and minor medical complications and the incidence of pressure sores in patients with a fracture of the hip. All patients admitted to Vancouver General Hospital with this injury between 1998 and 2001 inclusive were identified from our trauma registry. A review of the case notes was performed to determine the delay in time from admission to surgery, age, gender, type of fracture and medical comorbidities. A time-to-event analysis was performed for length of stay. Additionally, a Cox proportional hazards model was used to determine the effect of delay to surgery on the length of stay while controlling for other pertinent confounding factors. Using logistical regression we determined the effect of delay to surgery on in-hospital death, medical complications and the presence of pressure sores, while controlling for confounding factors.

Delay to surgery (p = 0.0255), comorbidity (p < 0.0001), age (p < 0.0001) and type of fracture (p = 0.0004) were all significant in the Cox proportional hazards model for increased time to discharge. Delay to surgery was not a significant predictor of in-hospital mortality. However, a delay of more than 24 hours was a significant predictor of a minor medical complication (odds ratio (OR) 1.53, 95% confidence interval (CI) 1.05 to 2.22), while a delay of more than 48 hours was associated with an increased risk of a major medical complication (OR 2.21, 95% CI 1.01 to 4.34), a minor medical complication (OR 2.27, 95% CI 1.38 to 3.72) and of pressure sores (OR 2.29, 95% CI 1.19 to 4.40).

Patients with a fracture of the hip should have surgery early to lessen the time to acute-care hospital discharge and to minimise the risk of complications.
