Injection therapy is twofold, first, intra articular or, secondly intra muscular or soft tissue. Intra articular injections are an effective tool in the management of osteoarthritic conditions of the foot and and ankle.
Osteoarthritis is basically the degeneration of the joint surfaces (cartilage), and inflammation scarring within the joint capsule as a result of wear and tear, or disease. This wear and tear may be from the result of trauma, of from poor joint alignment /biomechanical deficiency placing repetitive undue stress on or within the joint.
Injection therapy may involve the injection of corticosteroid, to act powerfully to reduce pain and inflammation. Within a joint the addition of local anaesthetic will actively disperse the steroid and possibly increase its beneficial action. Furthermore, the anaesthetic will help break down capsular scarring and adhesions -facilitating greater joint range of motion. Substances such as hyaluronidase,(Ostenil) may be injected to help reconstitute the synovial fluid to aid pain relief and improve the range of motion.
Injection therapy may also be used for many soft tissue complaints within the foot and ankle, such as planar fasciitis, Mortons’ Neuroma, Sinus tarsi, and bursitis.
Injection therapy may lead to side effects and should only be used as part an overall treatment strategy.
