[sub- + L. locatio, luxation (dislocation)]

subluxation

/sub·lux·a·tion/ (sub″luk-sa´shun)

subluxation

acromioclavicular joint injury

A disruption of the articulation formed between the acromion process and the clavicle, which may be accompanied by tearing of ligaments.
 
Sports involved
Football, wrestling, equestrianism, hockey.
 
Clinical findings
Pain at the top of the shoulder, decreased range of movement, splinting with arm held to the side; severe injury may be accompanied by a “lump” on the top of the shoulder.
 
Grading
Grade I—partial tear of the acromioclavicular ligament.
Grade II—complete tear of the acromioclavicular ligament and partial tear of the coracoclavicular ligament, accompanied by subluxation or partial displacement.
Grade III—complete disruption of the joint.

Management
Ice may alleviate pain and inflammation; grades I and II: use of a sling for pain; grade III may require open reduction and internal fixation, though there may be some disinclination to perform this manouevre for a non-break.

Mechanism
Direct downward blow to the tip of the shoulder.

subluxation

Chiropractic A motion segment in which the spine's alignment, movement or physiologic function is altered although contact between joint surfaces remains intact. See Dysfunction Orthopedics An incomplete joint dislocation with parts of the articular surfaces remaining in contact, with either a gradual displacement or partial dislocation within a joint; subluxations are contrary to a joint's plane or motion, or exceeds its ROM. See Range of motion. Cf Dislocation, Luxation.

subluxation (sub´luksā´shən),

n 1. an incomplete dislocation of a joint.
2. term applied to the temporomandibular joint, indicating relaxation of the capsular ligaments and improper relationship of the joint components, resulting in cracking and popping of the joint during movement.

subluxation

a partial dislocation. In the terminology of chiropractic, an abnormal positional relationship between contiguous vertebrae resulting in abnormal biochemical and neurological function.

angle of subluxation
in the Ortolani maneuver, the point at which the hip luxates. See also angle of reduction.

Patient discussion about subluxation

Q. Can a Chiropractor tell if your organs are shutting down?

A. She told me that because my spine is out of line so much, that it's causing my organs to shut down. I have been having bladder problems. I really think she is just trying to scare me.
