We present a very unusual case of an accessory articulation of the transverse processes of C6 and C7. Only four previous cases have been described in English literature. Our case stresses the importance of computed tomography (CT) and post-processing images to discriminate this variant from posttraumatic or degenerative lesions. Multiplanar reformations and volume-rendered images should be added to the cervical spine CT protocol.

Displaced ulnar collateral ligament injuries of the metacarpophalangeal joint of the thumb, also known as Stener lesions, are a well-recognized clinical entity, requiring surgical intervention because of the trapped location of the torn lateral collateral ligament superficial to the adductor aponeurosis of the thumb. We report a similar lesion located at the first metatarsophalangeal joint, to our knowledge the first ever described in the literature. In our patient, magnetic resonance imaging showed a full-thickness tear of the lateral collateral ligament of the first metatarsophalangeal joint, as well as a full-thickness tear of the extensor hood, with dislocation of the proximal part of the ruptured lateral collateral ligament to a position superficial to the extensor hood. Analogous to true Stener lesions, we are convinced these patients also need early surgical repair. Therefore, we would like to raise awareness about their existence to ensure adequate management of these lesions, in order to prevent possible long-term complications like chronic pain, instability, and joint degeneration.
