Treatment Guides

Method Of Administration

More Info

Arthramid® Vet is for intra-articular use only and must be administered by a qualified veterinarian familiar with the procedure in the intended species. 

Pre-Operative Procedures

More Info

Animals may be sedated to minimise stress and discomfort. Strict aseptic conditions must be followed at all times.

A 20G to 23G needle is placed intra-articularly. Synovial fluid should be observed. Care should be taken to avoid unnecessary damage of the intra-articular tissue, as this may result in diffuse swelling lasting for 24 to 48 hours. Remove the protective tip cap from the Arthramid® Vet syringe. Attach the syringe firmly into the Luer lock socket on the needle. Make sure the syringe is correctly mounted. The amount of Arthramid® Vet used is 1 – 4 mL. If necessary, attach a new Arthramid® Vet syringe during the procedure and continue the injection.

Post Injection Instructions

More Info

An ointment can be applied to the injection site immediately after treatment. A cold pack can be used on the injection site in case of an oedema. A bandage can be applied around the injection site if possible. Local or systemic corticosteroids should not be administered to the animal within two weeks of injection of Arthramid® Vet since this may mask a possible infection. The animal should be rested for 48 hours after the treatment.

Some animals can develop pain within the first postoperative hours. In addition, there is also a slight risk of haematoma and mild oedema. Within 1-2 weeks after treatment, there is a small risk that the animal may develop transient oedema and tenderness at the treatment site as the tissue integration is occurring. If not caused by infection, these reactions are self-limiting and will resolve within a couple of weeks. Non-steroidal anti-inflammatory drugs (NSAIDs) can be administered for pain relief and to reduce swelling. Allergic reactions to Arthramid® Vet have never been observed.

As with any intra-articular procedure, an Arthramid® Vet injection carries a risk of infection. Standard precautions and strict aseptic injection technique is essential. In the event of infection, the use of broad spectra antibiotics is recommended as a first-line treatment. Any use of corticosteroids is contraindicated in case of infection.

Dosage - Equine

More Info

Due to Arthramid® Vets’ unique mode of action, the following dosage recommendations have been made based on observed clinical responses to treatment. There is evidence to suggest that dose dependant response exists and that these doses may be altered depending on the severity or chronicity of the disease.

  • Distal Interphalangeal (DIP/ Coffin)- 1-2 mls
  • Metacarpo/tarso-phalangeal (Fetlock)- 2 mls
  • Carpus- 2mls
  • Tarso-metatarsal (TMT)/ Distal-intertarsal (DIT)- 1 ml
  • Tarsocrural- 2-3 mls
  • Shoulder- 3 mls
  • Stifles- 1-2 ml per compartment or 3-4mls for medial-femorotibial joint.

It is important to reassess cases at 4-6 weeks after first treatment Published clinical trials indicate horses that partially respond to initial treatment may benefit from a second dose at 4 to 6 weeks later.

Safety Studies indicate that concurrent treatment of multiple joints in the same animal is safe.

Comments From Clinical Practice

I have been using Arthramid Vet for 4 years treating TB’s, SB’s and equestrian horses. 90% of my work is lameness identification and treatment. I have injected over 600 joints with Arthramid Vet and have experienced no side  effects. I have used all of the alternative joint treatments over the last 50 years and consider Arthramid Vet (in conjunction with triamcinolone in an overall treatment strategy) superior to all other treatments. 85% of my TB lameness localises to the intercarpal joint.

I was one of the first vets to use Arthramid worldwide and have now used Arthramid for over 10 years in our clinic. We have injected over a thousand horses and have found it to be very safe. It has been a major game-changer in the way we treat OA in our patients. We have fantastic results with really frustrating cases and are still working on new indications and treatment schemes for the product. We are also looking into the ongoing research, especially around the Mode of Action. (read full)
