L1 vertebral body replacement using 3D-printed polylactic acid bioimplants

Background: The vertebral body plays a crucial role in supporting compressive loads and maintaining spinal biomechanics. An ideal biomaterial for total vertebral body replacement should combine biological and mechanical properties, yet no current material fulfills all criteria. This pilot study explores the use of a novel three-dimensional (3D)-printed porous polylactic acid (PLA) implant for total L1 vertebral...

Clear Cell Chondrosarcoma with Rib Cage Metastasis: Case Report

Clear cell chondrosarcoma is a rare histological subtype of chondrosarcoma, usually with a relatively non-aggressive clinical course. However, infrequently they may relapse and metastasize. We describe a case of a male patient, 53 years old, with rib cage metastases of a clear cell chondrosarcoma 11 years after the first surgical intervention, and review the literature.

Body composition, strength static and isokinetic, and bone health: comparative ...

Objective: To compare tissue composition, total and regional bone mineral content and bone mineral density, static hand grip and knee joint isokinetic strength between amateur soccer players and Control Group. Methods: Cross-sectional study. Air displacement plethysmography was used to estimate body volume and, in turn, density. Body composition, bone mineral content and bone mineral density were assessed for t...

Agreement between dual x-ray absorptiometers using pencil beam and fan beam: in...

OBJECTIVE: The current study was aimed to examine intra-individual variation on indicators of bone health in addition to whole-body plus appendicular tissue measurements using two concurrent assessments based on pencil beam and fan beam dual energy X-ray absorptiometry (DXA) systems in adult athletes from several sports. METHOD: Thirty-two male participants (27.6±10.1 years) were measured on anthropometry inclu...

Concurrent agreement between an anthropometric model to predict thigh volume an...

A variety of performance outputs are strongly determined by lower limbs volume and composition in children and adolescents. The current study aimed to examine the validity of thigh volume (TV) estimated by anthropometry in late adolescent female volleyball players. Dual-energy X-ray absorptiometry (DXA) measures were used as the reference method. Total and regional body composition was assessed with a Lunar DPX...

Linfoma primário da coluna vertebral: caso clínico

Os linfomas ósseos são pouco frequentes e raramente estão localizados à coluna vertebral, constituindo estas localizações geralmente manifestações secundárias. Os autores apresentam o caso clínico de uma doente de 58 anos de idade, com lombalgia mecânica de 6 semanas de evolução, sem resposta a terapêutica analgésica e anti-inflamatória e sem outras queixas acompanhantes. O estudo complementar revelou a existên...

Primary lymphoma of the spine: clinical case

Lymphomas of the bone are uncommon and only occasionally encountered in the spine, where they are usually secondary deposits.The authors report the case of a fifty-eightyear old woman with low back pain of six weeks duration, which did not improve with analgesics. Laboratory tests showed a normocytic anaemia and a raised erythrocyte sedimentation rate. Spinal X-Rays showed collapse of the L2 vertebra and increa...
