Overview

Prolotherapy.com is the website of the Hemwall Center for Orthopedic Regenerative Medicine, which runs two California offices, one in Valencia in the south of the state and one in Alameda in the north. The practice provides injection treatments for musculoskeletal pain rather than surgery.

Prolotherapy, its core service, involves injecting a concentrated dextrose (sugar) solution into an injured ligament, tendon or joint. The practice also offers platelet-rich plasma (PRP) prolotherapy, which uses a concentrate made from the patient's own blood, and what it calls biocellular stem cell-rich prolotherapy. Diagnostic ultrasound is used to look at the tissue and guide treatment.

The site sets out the technique's history, tracing it to work by Dr. Earl Gedney in the 1930s, and the centre is named after Dr. Gustav Hemwall, a long-standing figure in the field. The site does not publish the year this particular practice was established, its opening hours, languages spoken, or any arrangements for patients travelling from abroad.
