[Elbow hemiarthroplasty for coronal shear fractures of the distal humerus].

Objective: The aim of the operation is to replace the articular surface of the distal humerus in cases of nonreconstructible fractures of the distal humerus.

Indications: Active patients with high functional requirements, in whom weight limitation of total elbow arthroplasty should be avoided.

Contraindications: Contraindications include fractures with irreconstructible epicondyles and/or irreconstructible collateral ligaments, as well as ulnohumeral, or radiohumeral osteoarthritis.

Monteggia fractures and Monteggia-like-lesions: a systematic review.

Monteggia injuries are rare, but severe injuries of the elbow including various injury patterns. Treatment of these injuries is still topic of debate and strategies differ widely. In this systematic review on Monteggia injuries in adults, we aimed to clarify the incidence of different injury patterns within Monteggia injuries, investigate the main reasons leading to revision surgery and explore which surgical treatments should be favored to achieve satisfactory clinical results.
