The modified Harrington procedure for metastatic peri-acetabular bone destruction

Area of Science:

• Orthopedic Surgery
• Oncology
• Reconstructive Surgery

Background:

• Metastatic bone destruction in the peri-acetabular and iliac regions poses significant challenges for functional restoration.
• Traditional treatments may have limitations in addressing extensive pelvic bone loss.

Purpose of the Study:

• To evaluate the outcomes of a modified Harrington procedure for treating metastatic peri-acetabular and iliac bone destruction.
• To assess the safety and efficacy of this technique in improving patient function and relieving pain.

Main Methods:

• A modified Harrington technique was employed in nine patients (mean age 62.2 years) between 2006 and 2012.
• Total hip replacement implants, augmented with threaded pins and cement, were used to reconstruct the pelvis.
• The technique aimed to achieve stable construction for immediate full-weight bearing mobilization.

Main Results:

• Acetabular destruction varied, with Harrington's classification ranging from class II to IV.
• No intra-operative deaths or major complications (hemorrhage, infection, nerve injury, fixation loss, dislocation) were observed.
• Eight patients experienced improved functional status; four patients died from their underlying disease within 10-36 months.

Conclusions:

• The modified Harrington technique is an effective, reproducible, and long-lasting method for managing destructive metastatic lesions in the peri-acetabular bone and iliac wing.
• The procedure provides significant pain relief and functional improvement or restoration.
• Surgery was safely performed even in severely ill patients, with no intra- or postoperative deaths and no major complications.
