BACKGROUND It has been recognized that there is a distinction between shoulder laxity and shoulder instability and that there is a wide range of normal shoulder laxities. Our goals were (1) to evaluate if the ability to subluxate the shoulder over the glenoid rim in patients under anesthesia would be more prevalent than the inability to do so, (2) to determine if patients with a diagnosis of in...

In 1969 the results of a survey of atlanto-axial subluxation in all seventy-six consecutive rheumatoid patients attending a clinic were published (Mathews, 1969). Abnormal separation of the odontoid process from the anterior arch of the atlas was found in nineteen (25%) patients and was found to be more common in patients with more serious forms of the disease. In addition, an abnormal vertical...

Computed tomography (CT) immediately after double-contrast shoulder arthrography was taken in twenty-two young male patients with anterior shoulder instability including recurrent dislocation and subluxation. This recently developed technique called CT arthrography can provide significant information about patients with glenohumeral instability which is difficult to obtain by conventional arthr...

The results of operation for traumatic anterior dislocation of the head of the radius in eight children have been reviewed. We are satisfied on the basis of the results obtained and the outcome in one untreated patient that operative reduction is fully justified, provided that the annular ligament is reconstructed and internal fixation employed. We have not seen unilateral congenital dislocatio...

We report a 13-year-old child with Noonan Syndrome who developed spontaneous dislocation of the crystalline lens in anterior chamber leading to pupillary block glaucoma in the left eye and subluxation of lens in right eye. Intracapsular extraction of the dislocated lens was done in the left eye. Prompt diagnosis and management is needed in such cases to avoid glaucoma and corneal endothelial ce...

We present a case of intraocular pentastomiasis in a 12-year-old Israel Arab boy. A single secondary pentastomid larva, most likely of Linguatula serrata, was found in the anterior chamber of the right eye, attached loosely to the pupil's border by a fibrinous mass. Associated conditions were iritis, subluxation of the lens, and secondary glaucoma. This is the first documentation of human penta...

Proximal tibiofibular subluxation is the symptomatic hypermobility of the proximal tibiofibular joint. Pain along the lateral aspect of the knee must be carefully evaluated as the anatomy and biomechanics of this region are very complex. Anatomical variants of the proximal tibiofibular joint may be key to understanding the pathomechanics and, thus, treatment of this joint. The "horizontal" prox...

Iris-fixated IOLs, positioned either anterior or posterior to the iris plane, are an alternative to scleral-fixated posterior chamber IOLs or angle-fixated anterior chamber IOLs, with several advantages. Specifically, although scleral fixation of a posterior chamber IOL preserves the ocular anatomy, the surgical procedure is complex, with potentially severe complications, extended surgical time...

Rheumatoid arthritis (RA) is a chronic inflammatory disease involving multiple joints. The cervical spine is often affected, and cases involving atlantoaxial joint can lead to instability. Anterior atlantoaxial subluxation in RA patients can lead to posterior neck pain or occipital headache because of compression of the C2 ganglion or nerve. Here, we report the successful treatment of a RA pati...
