Athletes participating in noncontact sports involving abduction and external rotation of the shoulder (e.g., throwing) may develop occult recurrent subluxation manifested only as pain. The lack of contact trauma preceding symptoms, the failure of the athlete to appreciate the instability, the relative rarity that the lesion has been previously recognized and reported, and the lack of objective ...

We reviewed the evidence for hip surveillance in children with cerebral palsy from the published literature. Publications were identified using the Cochrane controlled trials register, the MEDLINE, EMBASE and CINAHL databases and by hand searching key journals and their references. Studies were included if they reported the frequency, associated risk factors or surveillance measures undertaken ...

BACKGROUND Disorders of the cervical spine are often observed in patients with rheumatoid arthritis (RA). However, the best head position for RA patients with atlantoaxial subluxation in the perioperative period is unknown. This study investigated head position during general anesthesia for the patients with RA and proven atlantoaxial subluxation. METHODS During anesthesia of patients with RA...

The description of the pivot shift test and its modifications is for the most part based on clinical observations. We wished to precisely determine the knee motions and medial-lateral tibiofemoral compartment subluxations that examiners induce in the knee joint to produce the pivot shift phenomenon. Eleven skilled knee surgeons performed the pivot shift test on an instrumented cadaveric lower l...

BACKGROUND: Shoulder subluxation is a frequent complication after stroke causing joint instability, shoulder pain, decreased activities of daily living, and impedance to rehabilitation progress. Electrical stimulation (ES) considered an effective modality reduce in acute stroke. However, few studies have investigated the effect position-triggered ES, which induces active muscle contraction thou...

In situ ulnar nerve release has been gaining popularity as a simple, effective, and low-morbidity procedure for the treatment of cubital tunnel syndrome. One concern with the technique is how to manage the unstable ulnar nerve after release. It is unclear how much nerve subluxation will lead to problems and surprisingly there is no grading system to assess ulnar nerve instability. I propose suc...

The authors present a case of a 24-year-old woman with left foot pain that began after an inversion injury obtained while running. The pain minimally improved with nonsteroidal anti-inflammatory medications. Clinical examination revealed a relatively normal foot with palpable changes in the bony structures at the midfoot consistent with a tarsal subluxation. Cuboid reduction was performed using...

The term subluxation has come to have different meanings for different health care professions in the United States for over the past century. This controversy has resulted in some contention both internal and external to the chiropractic profession. Some current factions within the chiropractic profession hold the term subluxation to be synonymous with the identity of chiropractic itself; howe...

Dorsiflexion, palmar flexion, ulnar translocation, and dorsal carpal subluxation are four, not uncommon, post-traumatic carpal ligamentous instabilities. Palmar carpal subluxation is a theoretical possibility. Dorsiflexion and palmar flexion instabilities are named for the way the distal lunate articular surface dorsally and palmarly, respectively. Ulnar translocation, and dorsal and ventral ca...
