There are several schemes for classification of lateral end clavicular fractures. Of these, the Neer classification is most widely used, Neer type I fractures are minimally displaced fractures that occur between or lateral to the intact coraco-clavicular ligaments. Neer type II fractures occur at the level of coraco-clavicular ligaments, with the trapezoid ligament remaining attached to the distal segment. Type II fractures can be further subdivided into type IIA, in which the conoid and trapezoid ligaments both remain attached to the distal fragment, and type IIB, in which the conoid ligament is torn. Type III injuries are intraarticular fractures that enter ACJ. Type IV fractures occur in children and they are considered physeal injuries. Type V fractures are multifragmentary fractures.The clavicle hook plate is designed to treat this problem by maintaining the acromioclavicular joint biomechanics and this allows early mobilization and avoids the need for reconstruction of the coraco-clavicular ligament.
