Background: Subluxation of the crystalline lens has various surgical management options. In moderate zonular dialysis, capsular bag may be preserved and used for intraocular (IOL) implantation using a tension ring or Cionni Capsular segment. It is technically demanding associated with high incidence complications such as IOL decentration, dislocation, posterior opacification (PCO). Advantages c...

Posterior chamber intraocular lens (PC-IOL) subluxation is uncommon but represents one of the most serious complications following phacoemulsification. Late spontaneous IOL-capsular bag complex dislocation is defined as occurring three months or later following cataract surgery. Unlike early IOL dislocation, late spontaneous IOL dislocation is due to a progressive zonular dehiscence and contrac...

Background: The trapeziometacarpal joint (TMCJ) is inherently unstable, relying on ligament restraint to preventsubluxation. Subluxation of the thumb in a dorsoradial direction is often observed in clinical practice, either after acuteligament injury or more commonly with osteoarthritis (OA). This subluxation follows loss of function of trapeziometacarpalligaments that stabilise this joint, res...

congenital anterior tibiofemoral subluxation is an extremely rare disorder. all reported cases accompanied by other abnormalities and syndromes. a 16-year-old high school girl referred to us with bilateral anterior tibiofemoral subluxation as the knees were extended and reduced at more than 30 degrees flexion. deformities were due to tightness of the iliotibial band and biceps femuris muscles a...

The aim of the study was to evaluate the significance of odontoid lateral mass interval (OLMI) asymmetry on open-mouth view, in neck injury patients who have otherwise normal cervical spine x-rays. Thirteen neck injury patients were reviewed. Average age was 23.5 years (range, 16-30 years) and average follow-up was 15 weeks (range, 6-39 weeks). All the patients, referred from the casualty depar...

AIM: To investigate the effect of Cionni-modified capsular tension ring (CTR) implantation in patients with severely traumatic subluxated cataracts. METHODS: All who totally had cataracts and lost zonule support underwent cataract surgery were retrospectively analyzed. Corrected distance visual acuity (CDVA), extent zonulysis, intraocular lens (IOL) position, intraoperative presentation, compli...

OBJECTIVE This article presents a personal view of the historical evolution of theories of subluxation in the chiropractic profession. DISCUSSION TWO MAJOR THEMES EMERGE FROM THIS REVIEW: those related to the mechanical behavior of the spine and those related to the neurologic implications of these mechanical issues. Chiropractic subluxation theory is one of the few health-related theories wh...

Craniocervical junction abnormalities with atlantoaxial subluxation caused by ventral subluxation of C2 were diagnosed in a 6-month-old female Pomeranian with tetraplegia as a clinical sign. Lateral survey radiography of the neck with flexion revealed atlantoaxial subluxation with ventral subluxation of C2. Computed tomography revealed absence of dens and atlanto-occipital overlapping. Magnetic...
