The Influence of Local Bone Status on Complications After Surgical Treatment of Distal Radius Fractures
Study Overview
Status
Detailed Description
Despite fractures of the wrist being widely regarded as "fragility fractures", there is good evidence that they are caused by diminished Bone Mineral Density (BMD) and that a low BMD value predicts a higher fracture risk at the distal radius. Both measurements of areal BMD with DXA and volumetric BMD with peripheral Quantitative Computer Tomography (pQCT)showed a lower BMD in women with Colles' fractures. Thus, Colles' fractures can be recognized as a good indication of underlying osteoporosis. High resolution peripheral Quantitative Computer Tomography at the distal radius will be evaluated in a subset of patients.
Clinical experts are concerned that osteoporosis increases the risk for poor outcomes and complication rates in surgical patients with osteoporosis. However, this has not yet been confirmed in clinical studies. It is important to investigate this question in order to correctly advise clinicians and patients and possibly develop tailored approaches for treatment of osteoporotic patients with distal radius fractures.

Patient self-assessment of wrist function questionnaire (PRWE)
Time Frame: Baseline
|
PRWE was developed to rate wrist-related pain and disability in functional activities.
This provides a score from 0-100, where higher scores indicate greater pain and disability.

Disabilities of the arm, shoulder and hand questionnaire (DASH)
Time Frame: Baseline
|
The disability of the arm, shoulder and hand (DASH) questionnaire is an upper extremity specific outcome measure.
The main part of the DASH is a 30-item disability/symptom scale concerning the patient's health status during the preceding week.
The scores for all items are then used to calculate a scale score ranging from 0 (no disability) to 100 (most severe disability).

High resolution pQCT of contralateral distal radius
Time Frame: within 6 weeks after surgery
|
High-resolution pQCT of the contralateral side with an XTremeCT will be performed in a subset of patients in Zürich.
To obtain the bone mineral content the CT values will be calibrated with the help of a phantom in hydoxyapatite (HA) densities in mg HA/cm3.
The relation of bone volume to tissue volume will be calculated as BV/TV.
These values will be analyzed separately.
