"Os" omovertebrale variants prove it to be a misnomer.
There are only a few case reports comprising exclusively of os omovertebrale. Here, we discuss various types, varied clinical presentations, associated abnormalities, and management strategies of this abnormality. We retrospectively analyzed three patients with os omovertebrale and their clinical presentation, and also reviewed the limited available literature. Patients were evaluated clinically and radiologically to diagnose this abnormality as well as the associated abnormalities. Two patients were operated for neurological deficits attributed to this deformity. It is quite common to miss this abnormality when it is of osseocartilaginous or fibrous type, especially when it is asymptomatic and not associated with Sprengel's scapula. By analyzing our patients and other reported cases, we have proposed a classification system. In addition, we discuss varied clinical presentations and their practical application. Os omovertebrale is a rare abnormality. It should be kept in mind and managed when encountered in clinical practice. The classification and clinicoradiological correlations described here can be useful to individualize management issues.
