Successful retrieval of a broken pituitary rongeur tip from the lumbar intervertebral disc space using a magnetic probe: illustrative case.

Background: Unexpected events such as instrument breakage during a routine lumbar microdiscectomy can pose a risk for nerve root injury, durotomy, infection, and anterior displacement into the retroperitoneal space. Removal of broken instruments requires planning, patience, and sometimes subsequent surgical procedures. Here, the authors explore the effectiveness of a magnetic probe for the retrieval of broken metallic (magnetic) pieces.

Single Dose of Tranexamic Acid Effectively Reduces Blood Loss in Patients Undergoing Spine Surgery: A Prospective Randomized Controlled Trial.

Objective: To evaluate the efficacy of oral administration of tranexamic acid (TXA) in spine surgery to achieve blood loss reduction.

Methods: Sixty patients undergoing major surgery of the spine were randomly assigned into 2 groups. Group 1 was assigned as the control group and the other group comprised patients who received oral administration of TXA 2 hours before surgery.

Scientometric Analysis of Publications from 2004-2021 in the Spine Surgery Field: A Latin American Perspective.

Objective: To determine characteristics of Latin American (LA) productivity in spine surgery published worldwide between 2004 and 2021 compared between periods and global literature.

Methods: A comprehensive search about LA productivity in the field of spine surgery using the Scopus and PubMed databases was performed in February 2022. The results were limited to articles published in indexed journals from 2004 to 2021.

Posterior Grade 4 Osteotomy With Vertebral Shortening Is Effective for the Treatment of Kyphosis Associated With Vertebral Discitis/Osteomyelitis.

Background: In the retrospective study of a prospectively maintained database, we present a case series of patients with kyphotic deformity secondary to spinal infection treated using a posterior-only approach with 3-column shortening and posterior instrumentation.

Methods: This is a case series of patients presenting with postural deformity and sagittal imbalance treated consecutively by 1 surgeon between 2012 and 2014. Clinical assessments and radiographic evaluations were made preoperatively and at 12- and 24-month postoperative follow-ups.

Characteristics of Spinopelvic Sagittal Alignment in Lumbar Degenerative Disease.

Background: Normal sagittal alignment shows a range of variations and normal values. This study compared sagittal vertebral alignment in patients with different degenerative lumbar diseases.

Methods: This cross-sectional study evaluated 300 patients who were enrolled between June 2016 and June 2017.

[Tratamiento quirúrgico de la escoliosis idiopática del adolescente. Resultados en el Instituto Nacional de Rehabilitación de México. Seguimiento mínimo de 24 meses].

Antecedentes: La escoliosis idiopática del adolescente se define como una deformidad tridimensional de la columna vertebral que se presenta entre los 10 y los 18 años, y que se manifiesta con una curvatura vertebral en el plano coronal mayor de 10°. Esta deformidad afecta al 2-3% de la población general, pero solo el 10% del total requerirá en algún momento tratamiento quirúrgico. El método de elección para el manejo es el uso de tornillos transpediculares y barras desrotadoras.

[Clinical presentation of a dorsal epidural arachnoid cyst after an epidural anesthesia].

Background: Arachnoid cysts are dural diverticula with liquid content similar to cerebrospinal fluid, with 1% occurring in the spinal cord. They locate mainly in the dorsal region of the thoracic spine, and are unusual causes of spinal cord compression.

Clinical Case: The case is presented of a previously healthy 15-year-old boy, with a 20-month history of spastic paraparesis that started apparently after epidural block for ankle osteosynthesis.

[Spinal osteochondroma: diagnostic imaging and treatment. Case reports].

Background: Osteochondromas are benign bony tumours, with only 1 to 4% being located in the spine. It occurs more frequently in the cervical spine, with C2 being the vertebra most affected. The neurological presentation is slow due to the growth characteristics of the tumour.
