Traumatic humeral articular cartilage shear (THACS) lesion in a professional rugby player: a case report

I-H Jeon, W A Wallace

A 20 year old male professional rugby player was seen at the clinic for evaluation of shoulder pain after rugby play. Magnetic resonance imaging showed extensive subchondral bone bruising of the humeral head with defect of the articular cartilage. Arthroscopy showed that the inferior half of the humeral head had extensive articular cartilage loss with nearly 70% of the inferior head having lost its cartilage. Sports medicine doctors should be aware that the shoulder joint in young competitive athletes playing contact sports may be exposed to greater risk of this kind of injury.

Avulsion fracture of peroneus longus at the first metatarsal insertion: a case report

T Murakami, K Okamura, S Harada, et al

Reports of isolated avulsion fracture at the planter lateral base of the first metatarsal without injury of the tarsometatarsal joint are very rare. A 24 year old man sustained an avulsion fracture at the plantar lateral base of the first metatarsal. Normal alignment of metatarsal bones and tarsometatarsal joint was maintained. In this paper, we describe internal fixation of the displaced fragment using x ray and minimally invasive surgery with good results.
