Over-zealous release of the first dorsal compartment of the wrist for de Quervain's disease or other lesions such as ganglia, may result in volar subluxation of the tendons of abductor pollicis longus and extensor pollicis brevis. This is usually asymptomatic, but may occasionally become disabling. We describe an operation using part of the extensor retinaculum to stabilise such a subluxation.

Background: Atlantoaxial subluxation occurs when there is misalignment of the atlantoaxial joint. Several etiologies confer increased risk in children, including neck trauma, inflammation, infection, or inherent ligamentous laxity cervical spine.
 Methods: A case study was performed. Demographics and clinical data were reviewed for etiology, imaging techniques, treatment, clinic outcomes.&...

We attempted to determine whether shoulder subluxation at the early stage of stroke can predict motor outcome in relation to the corticospinal tract (CST) state on diffusion tensor tractography.Fifty-nine stroke patients with severe hemiparesis were recruited. The patients were classified according to the distance of shoulder subluxation (group A: ≥2 cm, group B: <2 cm) and the affected CST on ...

We report a C2 tear-drop fracture of a 69-year-old patient which occurred after a fall. Although tear drop fractures of the subaxial cervical spine mostly develop due to a flexion type injury, the mechanism is often compressive hyperextension injury at the C2 vertebra. Rigid external stabilization and internal fixation are the treatment alternatives. Internal fixation may be performed using the...

Based on biomechanics several operational principles for the neutralization of a shoulder subluxation are described. The pros and cons of the operational principles are discussed. A detailed analysis of the forces acting on the upper and lower arm indicates a preference for only one of the operational principles and explains why the arm sling and hemisling fail in the elimination of subluxation...

OBJECT The objective of this systematic review was to use evidence-based medicine to identify the best methodology for radiographic assessment of cervical subaxial fusion. METHODS The National Library of Medicine and Cochrane Database were queried using MeSH headings and keywords relevant to cervical fusion. Abstracts were reviewed and studies meeting inclusion criteria were selected. The gui...
