Non-operative Treatment Versus Volar Locking Plate in Treatment of Distal Radius Fracture in Patients Over 65 Years

Non-operative Treatment Versus Volar Locking Plate in Treatment of Distal Radius Fracture in Patients Over 65 Years

Non-operative Treatment Versus Surgery With Volar Locking Plate in Treatment of Distal Radius Fracture in 65-year-old and Older Patients - a Prospective, Randomized Controlled Trial

The present collaboration study on the treatment of distal radius fractures is aimed to: (i) to compare non-operative treatment to volar plating in the treatment of initially malaligned distal radius fractures in patients aged 65 and older in terms of functional outcome measured with PRWE (ii) to compare non-operative treatment to volar plating in the treatment of distal radius fractures with early instability during follow-up, i.e., loss of reduction at 1 week (range 5 to 10 days) in patients aged 65 and older in terms of functional outcome measured with PRWE (iii)to compare pain, disability, quality of life, grip strength, and the number of complications after non-operative treatment and the initial and delayed operative treatment of distal radius fracture (iv) to assess the effect of pain catastrophizing score (PCS) on the functional outcome of non-operatively and operatively treated distal radius fracture (v) to assess the association between physical activity and the number of wrist movements measured with Axivity accelerometer and functional outcome measured with PROMs of non-operatively and operatively treated distal radius fractures (vi) to assess the effect of initial as well as the final radiological parameters on the functional outcome (vii) to assess the correlation of probability of radiological malalignment estimated by clinical prediction rule (EWC) with functional outcome measured with PRWE and PASS

Early ustable fracture: Phase 1: After closed reduction, if satisfactory reduction is not achieved fulfilling the inclusion criteria, the patient is allocated to Cohort 1. The patient is randomized to either non-operative (=Arm 1) or operative treatment (=Arm 2). Patients allocated to non-operative treatment will undergo a standard treatment protocol. Patients allocated to operative treatment will undergo a surgery with volar locking plate with modified Henry's volar approach.

Early stable fracture: Phase 1: After closed reduction, if satisfactory position is achieved, the patient is allocated to Cohort 2 and conservative treatment is performed as usually. Phase 2: Patients allocated to Cohort 2, will visit orthopedic outpatient clinic in 1 week in the hospital where the treatment was initially started. If reduction is maintained the patient will undergo standard follow-up visits. If reduction is lost to fulfill the inclusion criteria for surgery the patient is asked to participate to phase 2 of this study. After the patient´s enrollment has been confirmed and informed consent is signed, the patient is randomized to either non-operative (=Arm 3N) or operative treatment (=Arm 3O). If allocated to non-operative treatment patient will undergo the same protocol as those in the Arm 1. Patients allocated to operative treatment will undergo surgery with volar locking plate with standard volar approach.

PRWE is the primary outcome measure of wrist pain and disability in the study. The PRWE comprises 15 questions to measure wrist pain and disability in daily activities. In PRWE patients rate wrist pain and disability from 0 to 10 and it consists three subscales: Pain, Function and Cosmetics.

Disability of the wrist measured with the Disability of the Arm, Shoulder and Hand (QuickDASH) questionnaire

The QuickDASH is self-reported questionnaire and shortened version of DASH outcome measure to measure physical function and symptoms in people with any or multiple musculoskeletal disorders of the upper limb in 11 dimensions in 1-5 scale.

The 15D is a validated, generic, self-administered instrument for assessing the health related quality of life among adults. It combines the advantages of a preference-based and single index measure on a 0-1 scale.

The VAS is derived by health care professional question of pain in scale 0 to 10 in which 0 implies no pain and 10 the worst possible pain.

Grip strength is measured with a dynamometer in kg as the mean of three measurements. It will be numbered in percentage of the uninjured side.

The pain catastrophizing scale (PCS) is measured with a self-administered questionnaire. The PCS is designed to measure person's willingness to catastrophize the pain while they are experiencing it. In the questionnaire patients answer questions about how they feel and think when they are in pain and it can be taken while they are not experiencing pain.

Patient's self-assessment questionnaire will be analyzed to find out which parameters are of most importance for the patient.

Edinbourgh wrist calculator will be used to estimate the propability of loss of reduction during the follow-up.
