Iliofemoral Arthrodesis and Pseudarthrosis: A Long-Term Functional Outcome Evaluation

Constrained Total Hip Megaprosthesis for Primary Periacetabular Tumors

“…However, limb-salvage reconstruction of malignant pelvic tumors, especially in the periacetabular region, remains challenging because of the complex anatomy, the difficulty achieving wide surgical margins, and large bone and soft tissue defects after tumor resection. The reconstructive options include resection arthroplasty [7,30,33], iliofemoral or ischiofemoral arthrodesis [9,12], hip transposition method (pseudarthrosis) [3,12,32], free-vascularized fibular graft for pelvic ring reconstruction [29], allograft [2,22,23,26,39], recycled autologous bone graft [16,20], and endoprosthetic replacement [1,4,11,14,18,21,24,25,27,28,34,[36][37][38]. However, no standard reconstructive procedure exists after internal hemipelvectomy for malignant periacetabular tumors.…”

Outcome after pelvic sarcoma resection and reconstruction with a modular hemipelvic prostheses

“…Recently, however, limb salvage surgery in the pelvis is more common due to better function, quality of life and acceptable local recurrence. Though limb salvage surgery remains difficult and challenging, various methods were used to reconstruct the hemipelvis after periacetabular reconstruction resection, including ischiofemoral arthrodesis or pseudarthrosis, iliofemoral arthrodesis or pseudarthrosis [16],massive allograft [6,23,27,30],autoclaved autograft [20], allograft prosthetic composite [21,35], custom-made endoprosthesis combined with hip arthroplasty [1,17,38], modular saddle prosthesis [2,5,7] or modular hemipelvic endoprosthesis [37]. However, each method has its limitations, such as high complication or local recurrence rates or poor functional results after hemipelvic resection, etc [31].…”

Types of extended organ-sparing and reconstructive surgical interventions for tumor involvement of the cotyloid cavity

“…Осложнения в виде глубокого инфициро-вания раны и несостоятельности аутографта отмечены у 2 (50%) больных. Несмотря на то что, по мнению ряда авторов, эта ме-тодика отличается технической простотой выполнения операции, основными и значимыми ее недостатками яв-ляется частое развитие осложнений и неудовлетворитель-ный функциональный результат после операции [28][29][30][31][32].…”
