subluxation

 [sub″luk-sa´shun]
incomplete or partial dislocation.

sub·lux·a·tion

(sŭb'lŭk-sā'shŭn),
An incomplete luxation or dislocation; although a relationship is altered, contact between joint surfaces remains.
Synonym(s): semiluxation
[sub- + L. locatio, luxation (dislocation)]

subluxation

(sŭb′lŭk-sā′shən)
n.
Incomplete or partial dislocation of a bone in a joint.

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.

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.

Based on the data listed in Tables 2-5, the taping group showed an immediate and significant improvement in pain intensity, magnitude of subluxation, and AEMG on the first day immediately after taping, compared with the baseline (p < 0.05), whereas there was no significant changes in the control groups in these outcomes.
In sagittal plane with bone window, it is associated with an atlantoaxial subluxation at this level (anterior arch of C1 above C2 body), with a narrowing of the space available for spinal cord between the previous 2006 CT exam (e, white line measuring 1.5 cm) and recent 2014 CT exam (f, white line measuring 1.4 cm) in bone window.

Patterns of Involvement and Presence of Subluxation. The intraobserver agreement in defining zones of involvement according to Sanders and Frykberg's classification was almost perfect for pattern II (kappa intraclass correlation was 1.00) and substantial for patterns I and III (kappa intraclass correlation coefficients were 0.75 (SE 0.18) and 0.79 (SE 0.18), resp.).

Outside of chiropractic, the term subluxation refers to a displacement of a joint, less than a frank dislocation.

His first visit was after round 4 of a 29 week season following a severe subluxation. Suffering multiple minor subluxations within the last 2 seasons, the instability and soreness of his right shoulder was worsening, and he attempted to play on with conservative treatment through the season.
