Abstract
Long term outcomes of distal radius fractures have rarely been studied prospectively and do not traditionally extend past 1–2 years following treatment. The purpose of this study was to describe the long term patient-rated pain and disability of patients after a distal radius fracture and to also determine the differences in patient reported pain and disability after one year following injury and at the long term follow-up.
Patients who had previously participated in a prospective study, where baseline and standardised one year follow-up were performed following a distal radius fracture were contact to participate in this long term follow-up (LTFU) study. Eligible cases that consented agreed to evaluation which included being sent a package in the mail contain a letter of information and questionnaire. Baseline demographic data including age and sex, as well as date of fracture, mechanism of fall and attending physician information was obtained for all participating subjects. Patient rated pain and disability was measured at baseline, one year and at long-term follow-up using the Patient Rated Wrist Evaluation (PRWE). Patients were categorised as having had a worse outcome (compared to one year follow-up PRWE scores) if their LTFU PRWE score increased by 5 points, having no change in status (if their score changed by four or less points) or improved if their LTFU PRWE score decreased by 5 or more points.
Sixty-five patients (17 male, 48 female) with an average age of 57 years at the time of injury and 67 years at follow-up were included in the study. The mean length of follow-up was 10.7 (± 5.8) years (range: 3–19 years). Overall, 85% of patients reported having no change or had less patient-reported pain and disability (PRWE) at their long-term follow-up compared to their one year PRWE scores. As well, one year PRWE scores were found to be predictive (20.2%) of the variability in long term PRWE score (p=0.001).
This study provided data on a cohort of prospectively followed patients with a distal radius fracture, approximately 10 years after injury. This data may be useful to clinicians and therapists who are interested in determining the long term effects of this frequently occurring upper extremity fracture. The results of this study indicate that after 10 years following a distal radius fracture, 85% of patients will have good outcomes. The results of this study also indicate that majority of cases, if patients have a low amount of pain and disability at one year, then these outcomes will also be true approximately 10 years later.
