Case study 61 - Swan neck deformity/cervical kyphosis treated by cervical fusion The swan neck deformities are severe and complex cervical spine deformities. As a result of the cervical spine changes associated with a swan neck deformity, the upper part of the sub-axial spine becomes kyphotic. The lower part of the sub-axial cervical spine can subsequently compensate by becoming hyperlordotic. Deformity of the cervical spine typically results in an abnormal position of the head relative to the c

12K views · 57 reactions | We can see Swan-neck deformities whenever there's an issue affecting the volar plate of the proximal interphalangeal joint (PIP). The volar plate prevents hyperextension of the joint and can be affected in conditions such as rheumatoid arthritis, hypermobility, or after a trauma.  Silver ring splints can be used to stabilize the PIP joint but in some cases surgery may be required. #swan #hand #hypermobility #arthritis | Nick Pappas, MD | Facebook
