A Long Femoral Stem Is Not Always Required in Hip Arthroplasty for Patients With Proximal Femur Metastases

Zhiqing Xing MD, PhD, Bryan S. Moon MD, Robert L. Satcher MD, PhD, Patrick P. Lin MD, Valerae O. Lewis MD

During hip arthroplasties for treating proximal femur metastases, a long femoral stem frequently is used, presumably protecting the entire femur against progression of the existing lesions or development of new lesions. However, it is unclear whether a long stem is really required.

Surgical Technique: Computer-generated Custom Jigs Improve Accuracy of Wide Resection of Bone Tumors

Fazel A. Khan MD, Joseph D. Lipman MS, Andrew D. Pearle MD, Patrick J. Boland MD, John H. Healey MD

Manual techniques of reproducing a preoperative plan for primary bone tumor resection using rudimentary devices and imprecise localization techniques can result in compromised margins or unnecessary removal of unaffected tissue. We examined whether a novel technique using computer-generated custom jigs more accurately reproduces a preoperative resection plan than a standard manual technique.

Trends in the Surgical Treatment of Pathologic Proximal Femur Fractures Among Musculoskeletal Tumor Society Members

Matthew Steensma MD, John H. Healey MD

Several strategies for the treatment of pathologic proximal femur fractures are practiced but treatment outcomes have not been rigorously compared.

Locking Buttons Increase Fatigue Life of Locking Plates in a Segmental Bone Defect Model

Marc Tompkins MD, David J. Paller MS, Douglas C. Moore MS, Joseph J. Crisco PhD, Richard M. Terek MD

Durability of plate fixation is important in delayed union. Although locking plates result in stronger constructs, it is not known if locking affects the fatigue life of a plate. Two locking screws on either side of the nonunion could decrease working length and increase strain in the plate. However, the reinforcing effect of the locking head on the plate may compensate, so that it is unclear whether locking reduces fatigue life.

Prophylactic Stabilization for Bone Metastases, Myeloma, or Lymphoma: Do We Need to Protect the Entire Bone?

Hasham M. Alvi MD, Timothy A. Damron MD

The current operative standard of care for disseminated malignant bone disease suggests stabilizing the entire bone to avoid the need for subsequent operative intervention but risks of doing so include complications related to embolic phenomena.

Surgical Technique: Iliosacral Reconstruction With Minimal Spinal Instrumentation

Nader A. Nassif MD, Jacob M. Buchowski MD, Kelly Osterman RN, Douglas J. McDonald MD

Posterior pelvic ring reconstruction can be challenging and controversial. The choice regarding whether to reconstruct and how to reconstitute the pelvic ring is unclear. Many methods provide stability but often are technically difficult and require excessive dissection.

Poor Long-term Clinical Results of Saddle Prosthesis After Resection of Periacetabular Tumors

J. A. Jansen MD, M. A. J. Sande PhD, P. D. S. Dijkstra PhD

The saddle prosthesis originally was developed to reconstruct large acetabular defects in revision hip arthroplasty and was used primarily for hip reconstruction after periacetabular tumor resections. The long-term survival of these reconstructions is unclear.

Constrained Total Hip Megaprosthesis for Primary Periacetabular Tumors

Takafumi Ueda MD, PhD, Shigeki Kakunaga MD, PhD, Satoshi Takenaka MD, PhD, Nobuhito Araki MD, PhD, Hideki Yoshikawa MD, PhD

Limb-salvage reconstruction for periacetabular malignant tumors is one of the most challenging problems in orthopaedic oncology. Reconstructive options include resection arthroplasty, endoprosthesis, allograft, recycled autobone graft, arthrodesis, and pseudarthrosis. However, no standard procedure exists because of rarity and clinical variability of the disease. We previously developed a megaprosthetic system with a constrained total hip mechanism (C-THA).
