Ewing's Sarcoma of the Upper Extremity: Presenting Symptoms, Diagnostic Delay and Outcome.

Purpose: To look at the presenting features, Enneking stage, size of primary tumour, method of treatment and patient and doctor delays in upper extremity Ewing's sarcoma to observe the effects on local recurrence, metastasis and survival.

Patients And Methods: Nineteen patients with upper extremity Ewing's sarcoma were identified using the Scottish Bone Tumour Registry over the past 40 years.

Results: With increasing tumour Enneking stage at presentation there was a significantly higher mortality (P=0.

Inter- and intra-batch variability in the handling characteristics and viscosity of commonly used antibiotic-loaded bone cements.

Background: Several factors can affect the viscosity of a cement and therefore its handling characteristics. We performed an in vitro study to ascertain whether anecdotal observations of differences in handling between batches of the same brand of cement actually existed.

Methods: 3 batches of Simplex P Tobramycin (SPT), Refobacin Bone Cement (RBC), SmartSet GHV (SSG) and Palacos R+G (PRG) were tested.

In vitro comparison of Refobacin-Palacos R with Refobacin Bone Cement and Palacos R + G.

Background: Refobacin Palacos R (RPR) is no longer produced and Palacos R + G (PRG) and Refobacin Bone Cement R (RBC) have been introduced to supersede it. We performed an in vitro study to ascertain whether the handling and mechanical properties of the more recent cement preparations are different to those of their predecessor.

Methods: The 3 cements were tested to ISO 5833 and German DIN 53435 standards.
