What Is the Evidence in Treating Distal Radius Fractures in the Geriatric Population?

Relationship Between Malunion and Short-Term Outcomes of Nonsurgical Treatment of Distal Radius Fractures in the Elderly: Differences Between Early- and Late-Geriatric Patients

PURPOSE

Previous studies have suggested little association between radiographic malalignment and long-term functional outcomes of nonsurgical treatment of distal radius fractures in geriatric patients. However, no report has stratified the elderly by age and focused on short-term outcomes. The purpose of this study was to determine how the relationship between malunion and patient outcomes differs between early- and late-geriatric patients in the short and long terms after injury, thereby informing explanations and decision-making on treatment options for geriatric patients with distal radius fractures.

METHODS

One hundred patients treated nonsurgically for distal radius fractures were evaluated retrospectively; 52 were defined as early-geriatric patients (aged 60-72 years) and 48 as late-geriatric (aged >77 years). Malunion (dorsal tilt > 10°, ulnar variance > 3 mm, or intra-articular displacement or step-off > 2 mm), range of motion, and grip strength were investigated at 3 months. Multiple regression analysis was performed for each age group using Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores at 3 months as the dependent variable. QuickDASH scores over 1 year after injury were analyzed in the same way.

RESULTS

The early-geriatric patients included 33 acceptable unions and 19 malunions. The late-geriatric patients included 12 acceptable unions and 26 malunions. The significant predictors of QuickDASH scores at 3 months were malunion for the early-geriatric group and grip strength for the late-geriatric group (standardized coefficient β, 0.31 and -0.49, respectively). No factor significantly predicted the QuickDASH scores after at least 1 year in either group.

CONCLUSIONS

Malunion was associated with worse QuickDASH scores at 3 months after injury in the early-geriatric patients but not in the late-geriatric patients and did not predict the QuickDASH scores at 1 year after injury in either age group.

[Treatment reality of distal radius fractures in a center]

Distal radius fractures are the third most common type of fracture in Germany after fractures of the femoral neck and peritrochanteric femoral fractures. In 2019 a total of 72,087 cases were registered with an incidence of 106 cases per 100,000 inhabitants (81,570 fractures of the femoral neck, 73,785 peritrochanteric fractures). Many of these fractures are surgically treated also in this hospital but with controversial views on the optimal treatment. Against the background of the coronavirus disease 2019 (COVID-19) pandemic, disappearing personnel resources and the political pressure to form centers and a switch to outpatient treatment, the authors ask the question what the treatment reality in this hospital looks like and whether the general changes in the framework conditions also have an affect in this context. This is not a strictly scientific study but a stocktaking without any claims of completeness and the retrospective evaluation of a larger data pool with all its weaknesses. On the contrary, the data provide interesting aspects that are explained in detail in the individual sections.
