Objective: To report the intrathecal use of a hypobaric anaesthetic solution for partial hemipelvectomy in a nine-year-old, neutered female, Golden Retriever dog, weighing 34 kg.
Methods: Under inhalational anaesthesia, with the dog lying in lateral recumbency and the surgical side uppermost, 1.9 ml of a hypobaric solution containing 3.42 mg of bupivacaine and 0.66 mg of morphine were administered in the subarachnoid space at L5-6 level 30 minutes before surgery. Following the intrathecal injection the dog was maintained for five minutes in a 10 degrees head-down position, then for three minutes in a 10 degrees head-up position.
Results: Apart from a transient increase in heart and respiratory rates during resection of the sartorius muscle, which was treated with a plasma Target Controlled Infusion (TCI) of fentanyl, spinal anaesthesia provided cardiovascular stability and excellent relaxation of the surgical site. Neither motor blockade nor proprioceptive deficit were apparent in the contra-lateral hind limb at recovery, 200 minutes after injection. Postoperatively, rescue analgesia was not required in the 48 hours following surgery.
Clinical Significance: In dogs, the use of intrathecal hypobaric bupivacaine and morphine as a part of a balanced anaesthetic protocol should be considered during unilateral major orthopaedic surgeries of the pelvis and hind limb, as it allowed a reduction in the dose administered compared to isobaric solutions, providing selective spinal anaesthesia, excellent long-lasting analgesia, and rapid recovery of ambulation.

: The experience of unpleasant sensory phenomena after lower limb amputations (LLAs), including phantom limb pain (PLP), phantom limb sensation (PLS), and residual limb pain (RLP), impacts global healthcare and adversely affects outcomes post-amputation. This study aimed to describe the distribution of PLP, PLS, and RLP among patients with LLAs registered in the Heidelberg Amputation Registry. The primary objective was to determine the prevalence of sensory abnormalities across different amputation levels and causes.

Article Synopsis
- Internal hemipelvectomy is a surgery used to remove tumors from the pelvic area without losing a limb, but it can be tricky due to the complex areas involved.
- The study looked at patients who had this surgery and how well they did afterward, focusing on issues like complications and recovery.
- Researchers also reviewed other studies to gather more information on patient outcomes after this type of surgery.

Objective: To describe the clinical characteristics, procedural techniques, complications, and outcomes of dogs and cats undergoing any of the following modified hemipelvectomy techniques: concurrent partial sacrectomy and/or partial vertebrectomy, osseous excision crossing midline, and reconstruction without the use of local musculature.
Animals: 23 client-owned animals (20 dogs and 3 cats) that underwent modified hemipelvectomy techniques. Animals that underwent traditional (nonmodified) hemipelvectomy techniques were excluded.
A Modified Scapular-Parascapular Flap Design for Optimal Coverage of the Residual Limb.
Ann Plast Surg
October 2022
Department of Surgery, Uniformed Services University-Walter Reed National Military Medical Center Surgery, Bethesda, MD.
Article Synopsis
- Large soft tissue defects after major limb amputations are tough for surgeons due to the shape of the residual limb and the stress from prosthetics; using fasciocutaneous flaps based on the circumflex scapular system offers durable coverage without functional issues.
- Researchers reviewed cases from 2018 to 2021 where patients received a modified bilobed flap design for limb reconstruction, resulting in a significant increase in flap area compared to traditional methods.
- The study found that this modified flap design yielded no failures and provided a larger, more adaptable tissue coverage option specifically tailored for residual limbs.
Reconstruction of Type I-II Internal Hemipelvectomy in a Patient With Pelvic Myxoid Chondrosarcoma: A Case Report.

Pelvic chondrosarcomas are a major clinical challenge since the only therapeutic approach available is surgical resection. Reconstruction after partial resection of the pelvis including the acetabulum or the hip joint is a laborious and rigorous surgical procedure. Numerous complications are associated with different reparative methods.
