Acromioclavicular and sternoclavicular injuries and clavicular, glenoid, and scapular fractures.
Injuries to the acromioclavicular joint and the sternoclavicular joint and fractures of the clavicle, glenoid, and scapula vary widely in incidence, treatment, and prognosis. The treatment for acromioclavicular joint and clavicle injuries, which are relatively common, has significantly evolved. Controversy exists regarding the ideal treatment of type III acromioclavicular separations, whereas significant research has shown many potential benefits for surgically treating significantly displaced midshaft clavicle fractures that had traditionally been treated nonsurgically. ⋯ Most of these injuries can be treated conservatively, although some injuries will benefit from surgical fixation. Identifying floating shoulders or unstable glenoid neck fractures without bony or ligamentous stabilization requires an understanding of the multiple anatomic stabilizers of the glenoid. Floating shoulders, glenoid neck fractures with 1 cm or 40 degrees or more of displacement, and intra-articular glenoid fractures with associated glenohumeral instability or intra-articular displacement of 5 mm or more may require surgical repair.

Rapid advances in the field of orthopaedic trauma have improved treatment options while keeping pace with the changing characteristics of the trauma population. The availability of locking implants has changed the approach to treating fractures in older patients with osteoporotic bones as well as in those with comminuted and complex injuries. Minimally invasive approaches have allowed the preservation and protection of soft tissues while allowing adequate reduction and fixation of fractures. This biologically friendly approach coupled with newer implants and instruments will improve early and long-term outcomes in trauma care.

Hallux valgus correction by distal soft-tissue release and proximal metatarsal osteotomy is the procedure of choice for most patients with moderate and severe hallux valgus deformity. Complications can be avoided by selecting a procedure that provides adequate correction of the intermetatarsal angle and ensuring proper balancing of the metatarsophalangeal joint though lateral soft-tissue releases and medial joint plication. Arthrodesis should be considered when revision of failed surgery is planned, degenerative joint disease is present, and where the likelihood of failure of a bunion procedure is high (such as in elderly individuals with osteoporosis, severe deformity with significant involvement of the lesser metatarsophalangeal joint, and when spasticity is present). A review of biomechanical data, clinical studies, and surgical techniques is important for successful treatment of moderate and severe hallux valgus deformity.

It is important for physicians who treat upper extremity disorders to understand motor palsy or pain syndromes caused by compression of the median and radial nerves about the elbow and forearm. Patients with anterior interosseous nerve syndrome may report hand weakness, whereas those with pronator syndrome may present with pain and paresthesia that can be confused with carpal tunnel syndrome. Patients with posterior interosseous nerve syndrome report hand weakness, whereas those with radial tunnel syndrome report pain in the lateral elbow and forearm, which may be confused with lateral epicondylitis. Because each syndrome has overlapping symptoms, serial examinations are needed to determine the correct diagnosis.

Plate fixation of fractures began before the start of the 20th century. Initially, plates and screws were used to decrease deformity. There was minimal interest in the biology of fracture union. As knowledge increased in regard to the science of bone healing, fixation techniques and implants also evolved, from the development of rudimentary rigid constructs to stable locked plating.
