Orthokids Precise De-rotation Jig for Rotational Osteotomies of Humerus.

Humerus de-rotational osteotomies are one of the commonly done salvage procedures in children with residual brachial plexus birth injuries. Conventionally, the degree of angular correction was measured clinically intraoperatively by the ability to reach the occiput and the belly or it can be measured by putting reference k-wires at the appropriate angles. However, accurate angular correction is essential to success, as under-correction may lead to parental dissatisfaction and over-correction may lead to loss of mid-line function. The 'Orthokids Precise De-rotation Jig' (Nebula Surgical, Rajkot, INDIA) allows the exact measurement of the rotational correction required, which will lead to improved clinical outcomes. This accurate measurement mitigates the risk of errors due to parallax or eyeballing. The jig is handy, radio-opaque, autoclavable, and can be used without extensive dissection than what is required for the plate fixation.
