Body structures and physical complaints in upper limb reduction deficiency: a 24-year follow-up study.

Objective: To describe upper body structures associated with upper limb reduction deficiency and the development of these structures over time, to examine the presence of physical complaints in this population, and to compare body structures and complaints between groups based on prosthesis use.
Design: Prospective cohort study with a follow-up period of 24 years, with matched able-bodied controls.
Subjects: Twenty-eight patients with unilateral below-elbow reduction deficiency fitted with myoelectric prostheses, aged 8-18 years at inclusion.
Method: Measurements of upper arm, trunk and spine were performed and study-specific questionnaires were answered at baseline and follow-up; the Brief Pain Inventory and the Quick Disability of Arm, Shoulder, and Hand questionnaires were answered at follow-up.
Results: Both at baseline and follow-up, within-subjects differences in structures of the arm and trunk were shown in patients but not in controls. Spinal deviations, although small, were greater in patients compared to controls. Self-reported disability was higher in patients compared to controls. Differences in back pain and effect of prostheses use could not be shown.
Conclusions: Patients with unilateral below-elbow reduction deficiency have consistent differences in upper body structures. Deviations of the spine, probably of functional origin, do not progress to clinically relevant scoliosis.
