Pelvic Floor Functionality and Outcomes in Oncologic Patients Treated with Pelvic Bone Resection

Area of Science:

• Orthopedic Oncology
• Surgical Reconstruction
• Pelvic Floor Function

Background:

• Pelvic resections for bone tumors are complex orthopedic oncology procedures.
• These surgeries often involve significant bone and soft tissue removal.
• The impact on pelvic floor and related organ systems is a critical consideration.

Purpose of the Study:

• To evaluate the functional impact of pelvic bone tumor resections.
• Assessing effects on pelvic floor, digestive, urinary, and genital systems.
• Correlating surgical approach with functional outcomes.

Main Methods:

• Retrospective analysis of 30 pelvic bone tumor resections (2017-2024).
• Evaluation of reconstructive techniques including prostheses, allografts, and meshes.
• Assessment of pelvic prolapse (M-line, H-line, anorectal angle) and hydronephrosis via imaging.
• Quantification of urinary and fecal incontinence using the Pelvic Floor Impact Questionnaire (PFIQ7).

Main Results:

• Thirty cases analyzed with various reconstruction methods.
• Pelvic ring discontinuity correlated with higher pelvic prolapse grades (M-line).
• Patients with pelvic ring discontinuity reported worse PFIQ7 scores, indicating greater functional impairment.

Conclusions:

• Pelvic bone tumor resection poses significant challenges in orthopedic oncology.
• Surgical planning must consider pelvic floor and organ function alongside reconstruction.
• Intra-operative reconstruction and post-operative rehabilitation are recommended to mitigate functional deficits.
