Sonoma Orthopedic Products raises $22 million

Sonoma Orthopedic Products Inc. raised $22 million in its fourth round of venture funding.

The Santa Rosa business makes implants used to hold bones in place after they’re broken. Its devices are used to stabilize the collarbone or bones in the wrist -- they’re inserted into the bone via small incisions and are later removed through a simple operation when the bones have knitted.
