Progress in the treatment of varus-posteromedial rotation instability of the elbow / 中华创伤骨科杂志

ABSTRACT

As varus posteromedial rotatory instability (VPMRI) is not common, its injury mechanisms are complex and presents no obvious dislocation on X-ray, it may be considered as a simple coronoid fracture, likely leading to a missed diagnosis or misdiagnosis. Moreover, the treatment of VPMRI is also controversial. Conservative treatment or improper treatment can cause serious complications. Therefore, this review expounds on the injury mechanisms, anatomical structure, O'Driscoll classification, imaging examination, treatment and postoperative rehabilitation of this complicated elbow injury which is rare and difficult to treat clinically.
