Does valgus femoral osteotomy improve femoral head roundness in severe Legg-Calvé-Perthes disease?
Many surgeons perform a varus femoral or Salter pelvic osteotomy in patients with Legg-Calvé-Perthes (LCP) disease. However, more severely deformed femoral heads show greater congruency in adduction rather than in abduction. Therefore, a valgus-(flexion) femoral osteotomy (VFO) seems preferable rather than a varus femoral or Salter pelvic osteotomy. ⋯ Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

A novel imaging system permits real-time in vivo tumor bed assessment after resection of naturally occurring sarcomas in dogs.
Treatment of soft tissue sarcoma (STS) includes complete tumor excision. However, in some patients, residual sarcoma cells remain in the tumor bed. We previously described a novel hand-held imaging device prototype that uses molecular imaging to detect microscopic residual cancer in mice during surgery. ⋯ The ability to assess the tumor bed intraoperatively for residual disease has the potential to improve local control.
