Femoral neck stress fractures are rare and can be easily missed and failure to diagnose these injuries early can lead to avascular necrosis, malunion and osteoarthritis. It is important to have a high index of suspicion for femoral neck stress fractures in military recruits. We present three cases of bilateral femoral neck fractures in military recruits, all presenting with unilateral hip symptoms and signs. All the asymptomatic contralateral hips had femoral neck stress fractures diagnosed by screening MRI. Tension type and displaced femoral neck fractures were treated surgically. All the fractures managed healing without complications. Military recruits with unilateral groin pain should have an early referral for MRI hip to rule out femoral neck stress fractures and those military personnel with ipsilateral femoral neck fracture should have MRI of the contralateral hip. Two of the patients had vitamin D deficiency, of which one had elevated parathyroid hormones and low bone mineral density. Our case series highlights the significance of vitamin D deficiency among military recruits.
True aneurysms of the digital artery are very rare. Only 13 cases, caused by chronic trauma from occupational or sports-related overuse, have been reported. We present the first case of a true aneurysm of the digital artery of the left ring finger caused by chronic repetitive trauma from a wedding ring. The patient was a 44-year-old teacher who presented with a 1.5-cm subcutaneous mass on the radial aspect of the proximal phalanx of the finger, just proximal to the proximal interphalangeal joint. Exploration of the mass revealed a 1-cm aneurysm continuous with the radial digital artery. The aneurysm was excised and the proximal and distal ends of the radial digital artery ligated. Microscopic examination of the excised specimen confirmed the diagnosis of a true aneurysm with the lumen filled with an organising thrombus. The patient had an uneventful recovery with good wound healing, intact sensation, and normal capillary return.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
