Distinguishing Osteomyelitis From Ewing Sarcoma on Radiography and MRI.

Objective: The purpose of this study was to determine whether clinical and imaging features can distinguish osteomyelitis from Ewing sarcoma (EWS) and to assess the accuracy of percutaneous biopsy versus open biopsy in the diagnosis of these diseases.

Materials And Methods: Three radiologists reviewed the radiographs and MRI examinations of 32 subjects with osteomyelitis and 31 subjects with EWS to determine the presence of 36 imaging parameters. Information on demographic characteristics, history, physical examination findings, laboratory findings, biopsy type, and biopsy results were recorded.

Lower extremity reconstruction after limb-sparing sarcoma resection of the proximal tibia in the pediatric population: case series, with algorithm.

Limb salvage surgery (LSS) is the current treatment of choice for bone sarcomas in children. These procedures require composite resection and reconstruction, and are subject to high functional demands. Proximal tibia tumours, in particular, pose a significant challenge to treatment and reconstruction.

Surgical treatment of pediatric desmoid tumors. A 12-year, single-center experience.

Background: Pediatric desmoid tumors (PDTs) represent a group of rare, distinct lesions. While sparse, available literature suggests that PDT are particularly aggressive and difficult to control when compared with their adult counterpart.

Methods: A retrospective review identified 39 patients who underwent treatment of PDT at St.

A novel device for long bone osteodistraction: description of device and case series.

The purpose of this study was to present a novel intramedullary device (M-Bone; Phenix, Paris, France) that contains a mechanism for internal osteodistraction and bone transport in patients with segmental bone defects or limb length discrepancy after limb salvage operations. A total of five patients with primary bone tumors were enrolled in the study. After implantation, daily lengthening was performed in an outpatient setting either by the patient or with the help of a therapist, without the use of anesthesia.

Relationships among severity of osteonecrosis, pain, range of motion, and functional mobility in children, adolescents, and young adults with acute lymphoblastic leukemia.

Background And Purpose: Up to 38% of children receiving treatment for acute lymphoblastic leukemia (ALL) develop osteonecrosis, often without symptoms. Little is known about the association between the degree of osteonecrosis and functional mobility in this population. The purpose of this study was to examine relationships among the degree of osteonecrosis, pain, range of motion (ROM), and functional mobility in people with ALL.
