Chapter 1
General introduction and aims
Classifying forearm fractures
Chapter 2
Four distal radial fracture classifications tested among a large panel of Dutch trauma surgeons.
Normal forearm function represented in normative isokinetic strength measurements
Chapter 3
Grip strength is strongly associated with height, weight and gender in childhood: a cross sectional study of 2241 children and adolescents providing reference values
Chapter 4
The influence of hand preference on grip strength in children and adolescents; a cross-sectional study of 2284 children and adolescents
Chapter 5
Normative torque and grip strength profiles with variation in forearm rotation
Isokinetic pronation and supination strength measurements after forearm injury
Chapter 6
The effect of a Galeazzi fracture on the strength of pronation and supination two years after surgical treatment
Stellingen
1. There is not much agreement in the use of classification systems for distal radial fractures. (This thesis)
2. Grip strength difference in hand dominance is not significant accounted for in left hand dominance children. (This thesis)
3. The measurement of maximal grip strength in both hands of a toddler, does not only depend on following the observer’ instructions. (This thesis)
4. At 20° supination position, pronation and supination strength should be more or less equal, and therefore could provide clinicians with an easily obtainable and sensitive, though non-specific, indicative measure of forearm pathology. (This thesis)
5. Maximum torque can be reached when forearm position (pronation cq supination) is opposite to the direction of the torque (supination cq pronation). (This thesis) 6. Depending on expected growth in years in children, re-angulation can be observed independent of sex. (This thesis) 7. In DRUJ dislocation it is not the ulna that dislocates.
8. The implication of “sex” is scientifically clear and safer in use than “gender”.
9. When you gaze long into an abyss, the abyss also gazes into you (Nietsche)
10. Als poezen (in de ogen van mensen die poezen katten noemen) zich meer als een hond zouden gedragen, zouden het succesvollere huisdieren zijn.
11. De Kunst van te leven is thuis te zijn alsof men op reis is (Godfried Bomans) 12. Als het er niet meer is worden we zuinig. (Herman Brood)
Chapter 7
Supination and pronation strength deficits persist at 2-4 years after treatment of distal radius fractures
Chapter 8
Acceptance of angulation in the non-operative treatment of paediatric forearm fractures
Predicting outcome after paediatric forearm fractures
Chapter 9
The Evolution of Hand Function during Remodelling in Non-Reduced Angulated Pediatric
Forearm Fractures
Chapter 10
Predictors for losing reduction after reposition in conservative treated both-bone forearm fractures in 38 children Chapter 11 General discussion Summary Samenvatting Dankwoord CV
