Reconstruction of the Hemipelvis After the Excision of Malignant Tumours

Abstract

We treated 35 patients with primary malignant tumours of the periacetabular area by resection and prosthetic reconstruction of the defect. At a mean follow-up of 84 months, 15 patients (43%) were free from disease. The most common complications were deep infection (26%), local recurrence (24%) and recurrent dislocation of the hip (17%). The surviving patients achieved an average of 70% of their premorbid function. This method of reconstruction has a high morbidity and should be performed only at specialist centres, but the functional and oncological outcomes are satisfactory.

Oncologic and clinical outcomes in pelvic primary bone sarcomas treated with limb salvage surgery

“…Surgical treatment of pelvic sarcomas represents a challenge to orthopedic surgeons due to the extension and size of these sarcomas and the complexity of the pelvic anatomy [4][5][6][7][8]. Symptoms arising from primary bone sarcomas of the pelvic are often insidious in onset, originating delays in the diagnosis [9].…”

Periacetabular Reconstruction with a New Endoprosthesis

“…These implants experience hip joint reaction forces of up to 5.5 times body weight even with level walking [23], which theoretically may exceed the implant's minimal fixation; and, in the setting of tumor resection the implants may provide inadequate articular constraint in the setting of compromised soft tissue stabilizers. Subsequently, these cage derivations are associated with complication rates ranging from 39% to 83% and MSTS scores ranging from 37% to 70% [2,15,16,20,27,31]. The saddle design consists of a smooth cradle that rides in the ilium for both support and articulation [26].…”

Beckenteilresektion (innere Hemipelvektomie) und endoprothetischer Ersatz bei hüftgelenksnahen Tumoren

“…Operationsverfahren wie die ilio-bzw. ischiofemorale Arthrodese oder "super girdlestone" führen aufgrund einer signifikanten Beinverkürzung und Bewegungseinschränkung zu einem insgesamt schlechten funktionellen Ergebnis [17,18,19]. Bei kombinierten Defekten hat sich die Hüftverschiebeplastik nach Winkelmann als relativ komplikationsarmes Verfahren erwiesen, wobei jedoch auch hier eine signifikante Beinverkürzung in Kauf genommen wird [20,21].…”
