Ac Joint Grade 5

Ac separation shoulder separation shoulder dislocation grade 3 ac separation grade 5 ac separation.

Ac joint grade 5. This well known 6 type system is a modification of the earlier 3 class classification system described by allman 1967 2 and tossy 1963. Grade 4 involves posterior displacement or displacement backward. Grade 1 and 2 injuries are treated nonsurgically in a sling. Due to compression of the ac joint 4 treatment is usually nonoperative the focus of this standard of care except in severe sprains or fractures.

Grades i and ii never require. The ac gap is 5 mm. Grade 3 ac joint separation 16 months duration. This grade separation between the clavicle and the coracoid part of the scapula has to more than 100 more than double the normal side in order to fit the x ray definition of a type 5 joint separation.

X rays show one half separation of the ac joint ie clavicle displaced cephalad by one half the depth of the ac joint. It has the normal separation of 4 mm. 111 119 1963 grade 1. Tossy classification tossy et al corr 28.

A grade 5 ac joint separation occurs when the clavicle is severely displaced superiorly. Grade 2 involves rupture of the ac ligament or acromioclavicular ligament. Ac joint separation is graded from 1 to 5 with grade 4 and 5 treated with surgical repair or reconstruction. Acromioclavicular joint ac separations are one of the most common injuries seen in orthopedic and sports medicine practices accounting for 9 of all injuries to the shoulder girdle 1 3 various operative and nonoperative treatment schemes have been described for the management of ac joint injuries 4 33 although consider.

Coraco clavicular distance increased as compared to normal. A grade 3 ac joint separation and a grade 5 ac separation are both determined by the amount of vertical movement of the clavicle relative to the coracoid bone. It represents the most severe type of ac joint injury. No deformity visible clinically or on x ray grade 2.

Grade i is slight displacement of the joint and a badly stretched or partially torn ac ligament. Strain and contusions of ac joint. 5 acromioclavicular joint anatomy. Grade 1 is a simple sprain to the ac joint with minor damage to the ligament and no separation of bones.

Via x rays the injured side must be compared to the non injured side in order to determine the grade. Grade 3 rupture of both ac and cc or coracoclavicular ligaments which often results in an upward displacement of the clavicle bone. It takes into account not only the acromioclavicular joint itself but also the coracoclavicular ligament the deltoid and trapezius. Grade ii is a partial dislocation of the ac joint with a complete disruption tear of the ac joint and a partial disruption of coracoclavicular ligament.

Refer to figure 1 for anatomical reference. Grade 3 injuries typically can be treated nonsurgically however symptomatic or unstable grade 3 injuries can be treated surgically.
