Development of a novel WOrk-Related Questionnaire for UPper extremity disorders (WORQ-UP).

Purpose: The aim of this study is to develop a patient-reported outcome measure (PROM) that identifies work-related limitations among patients with upper extremity musculoskeletal disorders in order to enhance work-directed care in daily orthopaedic practice, and to assess its content validity.

Methods: The questionnaire was developed following the evaluation of existing PROMs and consensus within the research team. The content validity was assessed in three steps: (1) one on one interviews with patients (n = 14) were held to discuss the clarity and possible adaptation of items; (2) experts from the field (physiotherapists, insurance physicians, occupational health physicians, rehabilitation physicians and orthopaedic surgeons) were approached to participate in an interview to discuss the clarity, relevance and missing items; (3) patients (n = 12) were interviewed one on one to discuss the final version.

Reconstruction of the DRUJ in a young adult after resection of a large exostosis of the distal radius.

The prevalence of known solitary exostosis is around 1-2 % in the general population. Treatment of an exostosis may consist of resection with or without further treatment for deformity. The distal radioulnar joint (DRUJ) acts as the link between radius and ulna at the wrist and is important in the transmission of load.

Adductor longus tendon rupture mistaken for incarcerated inguinal hernia.

An incarcerated inguinal hernia is a common diagnosis, since the risk of an inguinal hernia incarcerating or strangulating is around 0.3-3%. An acute rupture of the adductor longus tendon is rarely seen and mostly affects (semi-) professional sportsmen.
