BACKGROUND Ligament restraints to terminal knee extension are poorly understood. HYPOTHESES (1) As with other motions of the knee, genu recurvatum is limited primarily by a named, identifiable structure. (2) As the largest static structure of the posterior knee, the oblique popliteal ligament is uniquely suited to act as a checkrein to knee hyperextension. STUDY DESIGN Descriptive laborator...

BACKGROUND Children with Joint Hypermobility Syndrome (JHS) have reduced knee joint proprioceptive acuity compared to peers. Altered proprioception at end of range in individuals with JHS is hypothesised to contribute to recurrent joint injuries and instability. This study aims to provide the first objective comparison of functional knee joint proprioceptive acuity in hyperextension range compa...

Vertebral Artery Occlusion Following Hyperextension and Rotation of the Head • This is a case report of a lateral medullary syndrome of Wallenberg following occlusion of one vertebral artery and stenosis of the opposite artery precipitated by combined motion of hyperextension, rotation, and lateral flexion of the head within physiological limits. Sufficient duration of such head position appear...

[Purpose] The purpose of this study was to investigate on the effects of the stepwise application of orthosis and kinesiology tape on a patient with thumb metacarpophalangeal joint hyperextension injury. [Subject] The patient was a 43-year-old man with severe thumb MCP pain and extremely limited thumb movement. [Methods] Stepwise application of orthosis and kinesiology taping were performed for...

Hyperextension injury of the tarsometatarsal joint (TMTJ) is a debilitating injury and arthrodesis of this joint is often the only procedure that can result in full return to function. Most surgical procedures described for arthrodesis of the tarsometatarsal joint necessitate the use of external, splint or cast, to protect the implants used from fatigue failure. This report describes the succes...

Scapho-capitate fracture (Fenton syndrome) is a rare lesion and is even less well-documented in adolescents. The most frequent mechanism is possible forced extension and hyperextension of the wrist. We report a case of 15 years old boy with hyperextension injury to the wrist. The true diagnosis was made 2 weeks later. Treatment involved open reduction and internal fixation with K-wires and Herb...

The Pre-Caledonian margin of Baltica has been outlined as a tapering wedge with increasing magmatism towards the ocean–continent transition. It is, however, well known that margins are complex, different and diachronous evolution along across strike. Baltica’s vestiges in Scandes have complexities akin to modern margins. included microcontinent magma-poor hyperextended magma-rich segments. was ...
