The patient-rated wrist evaluation (PRWE) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire are patient-reported outcome measures (PROMs) used for clinical and research purposes. Methodological high-quality clinimetric studies that determine the measurement properties of these PROMs when used in patients with a distal radial fracture are lacking. This study aimed to validate the PRWE and DASH in Dutch patients with a displaced distal radial fracture (DRF). The intraclass correlation coefficient (ICC) was used for test-retest reliability, between PROMs completed twice with a two-week interval at six to eight months after DRF. Internal consistency was determined using Cronbach’s α for the dimensions found in the factor analysis. The measurement error was expressed by the smallest detectable change (SDC). A semi-structured interview was conducted between eight and 12 weeks after DRF to assess the content validity.Objectives
Methods
Traumatic brachial plexus injury causes severe functional impairment
of the arm. Elbow flexion is often affected. Nerve surgery or tendon
transfers provide the only means to obtain improved elbow flexion.
Unfortunately, the functionality of the arm often remains insufficient.
Stem cell therapy could potentially improve muscle strength and
avoid muscle-tendon transfer. This pilot study assesses the safety
and regenerative potential of autologous bone marrow-derived mononuclear
cell injection in partially denervated biceps. Nine brachial plexus patients with insufficient elbow flexion
(i.e., partial denervation) received intramuscular escalating doses
of autologous bone marrow-derived mononuclear cells, combined with
tendon transfers. Effect parameters included biceps biopsies, motor
unit analysis on needle electromyography and computerised muscle tomography,
before and after cell therapy.Objectives
Methods
To investigate the differences of open reduction and internal
fixation (ORIF) of complex AO Type C distal radius fractures between
two different models of a single implant type. A total of 136 patients who received either a 2.4 mm (n = 61)
or 3.5 mm (n = 75) distal radius locking compression plate (LCP
DR) using a volar approach were followed over two years. The main
outcome measurements included motion, grip strength, pain, and the
scores of Gartland and Werley, the Short-Form 36 (SF-36) and the
Disabilities of the Arm, Shoulder, and Hand (DASH). Differences
between the treatment groups were evaluated using regression analysis
and the likelihood ratio test with significance based on the Bonferroni
corrected p-value of <
0.003.Objectives
