Ultrasound diagnosis of bowler's thumb in a 60-year-old man.

Bowler's thumb is an uncommon traumatic neuropathy of the thumb ulnar digital nerve. We present a case of bowler's thumb in an individual who is an avid bowler, however, only manifesting following an unrelated injury. We describe the clinical and imaging findings, differential diagnostic considerations, and the treatment options.

Bone flap infections after craniotomy: a review of 63 cases and the implications for definitions, classification and surveillance methodologies.

Background: Bone flap infections (BFIs) occur following neurosurgical procedures such as craniotomies. However, they are poorly defined and often not clearly differentiated from other surgical site infection in neurosurgery.

Aim: To review data from a national adult neurosurgical centre to explore some clinical aspects to better inform definitions, classification and surveillance methodologies.
