What is Hemipelvectomy?

Hemipelvectomy is a surgical procedure used in dogs to treat masses located on the pelvis by removing all or part of the pelvis and, in some cases, the attached limb. There are two main types of hemipelvectomy: partial and total. Partial involves removing only part of the hemipelvis, while total hemipelvectomy will result in the removal of the entire hemipelvis and the attached limb. This is an invasive and aggressive surgery and is not generally the first line of treatment for conditions affecting the pelvis. It is a highly complex and specialized procedure that requires extensive knowledge of the pelvic region.

Hemipelvectomy Procedure in Dogs

The approach to hemipelvectomy will vary based on the location of the tumor or mass. The attached limb and other parts of the pelvic region may or may not need to be removed. The general approach to total hemipelvectomy is detailed below.

  1. Blood work, x-rays, and other diagnostic testing will be conducted prior to surgery to ensure anesthetization is safe for the dog and to visualize the mass(es).
  2. The surgeon may decide to acquire blood from a veterinary blood bank prior to surgery in case of severe perioperative hemorrhage.
  3. The dog will be given general anesthesia and analgesics.
  4. The surgeon will shave, clean, and drape the operative area and place a urinary catheter.
  5. A stay suture is placed on the rectum so the dog does not empty bowel contents during surgery.
  6. The surgeon will incise the skin and separate the hip muscles along their natural seams.
  7. Surgical swabs soaked in a saline solution will be used to keep the muscle moist throughout surgery.
  8. The surgeon will ligate, or cut off blood supply to, the major arteries and veins of the hip to prevent hemorrhage.
  9. The abdominal muscles attached to the pubis are cut and separated. The external iliac artery and vein are then isolated and double ligated.
  10. The surgeon will repeat the previous step for the iliopsoas muscles.
  11. The sacrum is exposed, allowing for the elevation of the ilium.
  12. An oscillating saw is used to cut the pubic symphysis, and the attached limb is lifted so the muscle attachments can be incised.
  13. Certain nerves are then separated from the hemipelvis and amputated limb.
  14. A local anesthetic is administered to the nerve sheath.
  15. A saline solution is used to flush the surgical site.
  16. For dogs requiring radiation treatment, the surgeon may decide to place metal hemoclips.
  17. The surgeon will replace the muscles and close the wound.
  18. For sexually intact dogs, castration should be considered because hemipelvectomy will increase the likelihood of testicular injury.
  19. The dog will be hospitalized for up to ten days.

Efficacy of Hemipelvectomy in Dogs

The efficacy of hemipelvectomy will vary based on the expertise of the surgeon, the overall health of the dog, and the underlying condition it is used to treat. Given that the surgeon is highly skilled and the dog is relatively healthy prior to surgery, hemipelvectomy is typically effective. This procedure carries a recurrence rate of approximately 16%. Dogs tend to recover and adjust to the loss of the limb relatively quickly.

Hemipelvectomy Recovery in Dogs

The dog will need to be hospitalized after surgery. Most dogs will be discharged within seven days. Analgesics and anti-inflammatories will be administered throughout the hospitalization period. The veterinarian may attempt to help the dog walk within forty-eight hours after surgery.

Healing times depend on the size and health of the dog, the efficacy of surgery, and the underlying condition. Larger dogs may require supportive walking therapy for up to four days after surgery. Dogs may need to wear an Elizabethan cone to avoid irritating the surgery site. The surgery site should be checked daily to make sure no bleeding, drainage, or swelling has occurred. If owners observe any abnormalities in urination and defecation, they should consult their veterinarian immediately.

A follow-up appointment will be scheduled within fourteen days to remove sutures. The veterinarian may schedule additional follow-up appointments to administer other treatments, including chemotherapy and radiation.

Cost of Hemipelvectomy in Dogs

The cost of hemipelvectomy will vary based on standards of living and additional costs incurred. On average, the cost of hemipelvectomy in dogs ranges from $3,500 to $4,200.

Dog Hemipelvectomy Considerations

Complications associated with hemipelvectomy may range from moderate to severe. These include, but may not be limited to:

  • Hemorrhage
  • Rupture of the surgical site
  • Infection
  • Incisional hernia
  • Urethral or rectal trauma
  • Pressure point sores
  • Tumor recurrence

The recurrence rate of tumors in dogs treated with hemipelvectomy is approximately 16%. Severe hemorrhage is a significant risk of this surgery because of the large muscles involved. Approximately 80% of small animals that undergo this surgery do not experience any complications. The remaining 20% do not experience life-threatening complications.

Hemipelvectomy Prevention in Dogs

Cancer cannot be prevented in dogs. However, for cases of pelvic fracture, it is imperative that owners follow their veterinarian’s recovery instructions carefully. Delayed and improper healing may warrant hemipelvectomy, and will cause more pain for the dog.

My pet has the following symptoms:
No Appetite
My dog had surgery a month ago to remove a mass in the pelvic area, she has recovered from that and the tumor was benign. However, shortly after the surgery when the anestesia was wearing off, she tried to stand up and her legs played out from under her to the sides and it seems that she tore the recently sutured muscles. Since then we have had her convalescing with her back legs tied together about six inches apart to see if the muscles will heal themselves and not require further surgery. We have to change the paper bandage daily as when she urinates she wets it and weakens it. Like this she is able to walk, get in and out of her bed etc. Today, she was out with my husband when the bandage broke and he could see that her back legs still continue to splay out, so he picked her up. My question is, what do you think her prognosis is? Will this heal by itself or will she require further surgery? Is the surgery likely to be successful? My vet here in Spain seems to think so, but he also says this is a very rare case and hasn't seen one like this before. My email address is ilovebcn@yahoo.com

Thank you for your email. Without knowing exactly what surgery Chula had, I have a hard time commenting on whether she will recover from this injury - I'm not sure the extent of muscle damage that occurred. If the muscles are going to heal, it sounds like you are doing everything that you can to help facilitate that, and it is positive that your veterinarian seems to think that they will, as he has seen Chula and knows more about her situation. It may take longer to heal because she is a little older, but things do tend to heal, and a month isn't very long to recover from a major injury. I hope that she continues to heal and does well!
