Conservative surgical management of surface osteosarcoma using 3D printing technology: An unusual case report and literature review.

Introduction And Importance: Surface osteosarcoma, a rare variant of osteosarcoma, poses unique challenges in diagnosis and treatment. This report discusses the application of 3D printing technology in the surgical management of a complex case involving a 27-year-old female patient with surface osteosarcoma in the proximal tibia.

Case Presentation: A 27-year-old female patient presented with a progressively growing mass on her right knee, initially misdiagnosed as a benign bone tumor.

[Predictive criterions of unrecognized articular effraction after internal fixation of femoral neck fractures].

On the basis of a retrospective study comprising 91 cases of femoral neck fracture treated by DHS, unrecognized screw articular penetration was observed in 9 cases (9.9%). The coxa valga (Garden I) fractures are the most interested by this complication (7 cases out of 9).

Concomitant alar and apical ligament avulsion in atlanto-axial rotatory fixation. Case report and review of the literature.

The authors report a case of Fielding type II acute atlanto-axial rotatory fixation (AARF). The CT scan with coronal reconstruction showed an avulsion of the apical and right alar ligament. These findings are exceptionally reported in the literature, especially concerning the apical ligament which might be a stabiliser in flexion and extension of the occipitocervical joint.
