Treatment of Metastatic Carcinoma to the Hip with CT-guided Percutaneous Acetabuloplasty: Report of Four Cases

Percutaneous Acetabuloplasty Compared With Open Reconstruction for Extensive Periacetabular Carcinoma Metastases

“…Cement acetabuloplasty has been reported to be a safe and successful procedure for periacetabular carcinoma metastases [6][7][8][9][10][11][12]14]. The largest series to date describes this procedure in 25 patients and measures functional outcome using an array of measures such as the Harris Hip Score, Western Ontario and McMaster Arthritis Index (WOMAC), ECOG performance status, and VAS for pain [9].…”

“…The technique has been well described by its originator and previously by our group [10,12]. We calculated a lesional filling score based on measurement of the largest cross sectional area of a given lesion in coronal, axial, and sagittal planes on postoperative 2 mm-slice CT scans.…”

“…An example is cement acetabuloplasty [4]. Derived from the technique of vertebral augmentation using injected polymethyl-methacrylate (PMMA) [5], this technique has received enthusiasm for its effectiveness and minimally-invasive nature [4,[6][7][8][9][10][11]. In theory, percutaneously injected cement not only provides structural buttressing even with subtotal lesional filling [12], but also provides some adjuvant effect due to thermal tumor necrosis.…”

Palliation of compression fractures in cancer patients by vertebral augmentation: a retrospective analysis

“…They have been deemed safe and durable procedures in appropriate patients 4and have been used individually, and/or in conjunction with local radiation therapy, to treat compression fractures 8. The clinical benefit of VA in cancer patients has led to early reports of treatment outside of the spine with promising results seen in the acetabulum and calcaneus 16 17. Although there is a suggestion that these techniques provide pain relief in cancer patients, the literature currently lacks large analyses of the safety and efficacy of these procedures in this subset of patients 18 19…”

Evaluating the safety and effectiveness of percutaneous acetabuloplasty

“…Percutaneous ablation techniques, such as radiofrequency ablation (RFA) and cryoablation, have been shown to produce significant pain reduction but do not address the increased risk of pathologic fracture in this weight bearing region 6. Percutaneous acetabuloplasty is an image guided intervention in which acrylic cement is injected directly into the lesion in order to provide pain relief and potential structural support 6 7. Anecdotal reports suggest immediate and long term pain relief using this approach 3…”
