How 3D patient-specific instruments improve accuracy of pelvic bone tumour resection in a cadaveric study
OBJECTIVES To assess the accuracy of patient-specific instruments (PSIs) versus standard manual technique and the precision of computer-assisted planning and PSI-guided osteotomies in pelvic tumour resection. METHODS CT scans were obtained from five female cadaveric pelvises. Five osteotomies were designed using Mimics software: sacroiliac, biplanar supra-acetabular, two parallel iliopubic an...
متن کاملPrimary Amenorrhea with Nonspecific Pelvic Mass: A Rare Case Report
Menstrual disorders are common in puberty, but they are of great concern to patients when presented with primary amenorrhea. This paper reports the case of a 17-year-old single female with secondary sexual characteristics and a suspicious mass in pelvic floor. She also complained from chronic pelvic pain. In laboratory tests, the hormone levels were normal and ultrasound scan showed a 50 to 89...
متن کاملSurgical Guides (Patient-Specific Instruments) for Pediatric Tibial Bone Sarcoma Resection and Allograft Reconstruction
To achieve local control of malignant pediatric bone tumors and to provide satisfactory oncological results, adequate resection margins are mandatory. The local recurrence rate is directly related to inappropriate excision margins. The present study describes a method for decreasing the resection margin width and ensuring that the margins are adequate. This method was developed in the tibia, wh...
متن کاملTumor resection at the pelvis using three-dimensional planning and patient-specific instruments: a case series
BACKGROUND Sarcomas are associated with a relatively high local recurrence rate of around 30 % in the pelvis. Inadequate surgical margins are the most important reason. However, obtaining adequate margins is particularly difficult in this anatomically demanding region. Recently, three-dimensional (3-D) planning, printed models, and patient-specific instruments (PSI) with cutting blocks have bee...
متن کاملComputer-Assisted Planning and Patient-Specific Instruments for Bone Tumor Resection within the Pelvis: A Series of 11 Patients
Pelvic bone tumor resection is challenging due to complex geometry, limited visibility, and restricted workspace. Accurate resection including a safe margin is required to decrease the risk of local recurrence. This clinical study reports 11 cases of pelvic bone tumor resected by using patient-specific instruments. Magnetic resonance imaging was used to delineate the tumor and computerized tomo...
