Resection of a tumor of the pelvis is most disabling when the acetabulum is excised and a durable reconstruction of the defect is hard to achieve. All available methods are associated with frequent complications. Few large series have been published, and fewer have focused entirely on complete resections of the acetabulum. The use of an allograft-prosthetic composite allows customization on the operating table. However, while such composites restore anatomy and function of the pelvis the use of pelvic allografts is controversial and the durability is unknown.
Unplanned excision of a soft tissue sarcoma generally requires reexcision to achieve an adequate surgical margin. Many surgeons assume delay of definitive surgery adversely affects patient survival and local recurrence. However, no clear evidence of this assumption can be found in the literature.
Treatment of giant cell tumor of bone (GCT) often is complicated by local recurrence. Intralesional curettage is the standard of care for primary GCTs. However, there is controversy whether intralesional curettage should be preferred over wide resection in recurrent GCTs.
Many surgeons treat giant cell tumor of bone (GCT) with intralesional curettage. Wide resection is reserved for extensive bone destruction where joint preservation is impossible or when expendable sites (eg, fibular head) are affected. Adjuvants such as polymethylmethacrylate and phenol have been recommended to reduce the risk of local recurrence after intralesional surgery. However, the best treatment of these tumors and risk factors for recurrence remain controversial.
Vascular reconstruction in infants constitutes a surgical challenge and is indicated frequently for acute occlusions. With the presence of a subacute vascular occlusion, including that produced by tumor resection, collateral circulation develops quickly. Thus a surgeon can consider tumor and vessel resection, without the need for vascular reconstruction.
Adductor Myocutaneous Flap Coverage for Hip and Pelvic Disarticulations of Sarcomas with Buttock Contamination
Hip disarticulation and hemipelvectomy are alternatives to limb-salvage procedures for patients with extensive tumors of the upper thigh and buttocks. In cases when neither the conventional posterior gluteus maximus flap nor the anterior quadriceps flap can be used because of the location of the tumor, a medial adductor myocutaneous flap may be an alternative.
