Biportal endoscopic cervical open-door laminoplasty to treat cervical spondylotic myelopathy.

Background: Although cervical laminoplasty is a frequently utilized surgical intervention for cervical spondylotic myelopathy, it is primarily performed using conventional open surgical techniques. We attempted the minimally invasive cervical laminoplasty using biportal endoscopic approach.

Methods: Contralateral lamina access is facilitated by creating space through spinous process drilling, followed by lamina hinge formation.

Biportal endoscopic transforaminal thoracic interbody fusion for the treatment of thoracic myelopathy.

Background: Biportal endoscopic spine surgery independently controls two hands, similar to microscopic surgery, and utilizes a broader working space that is not disturbed by retractors under clear-magnified endoscopic vision. These advantages facilitate successful neural decompression and safe transforaminal interbody fusion, even in patients with thoracic spondylotic myelopathy.

Methods: A wide laminectomy and precise total facetectomy, in conjunction with partial pediculotomy, establish a secure transforaminal space for cage insertion.

Biportal Endoscopic Posterior Thoracic Laminectomy for Thoracic Spondylotic Myelopathy Caused by Ossification of the Ligamentum Flavum: Technical Developments and Outcomes.

Objective: Advanced biportal endoscopic surgery techniques can be used to treat thoracic myelopathy secondary to ossification of the ligamentum flavum (OLF). This case series elaborates on a feasible biportal endoscopic technique for thoracic OLF removal and evaluates clinical and radiological outcomes.

Methods: A biportal endoscopic posterior thoracic laminectomy was performed to remove the thoracic OLF.

Association of depression and anxiety disorder with the risk of mortality in breast cancer: A National Health Insurance Service study in Korea.

Purpose: To examine whether depression, anxiety disorder, and their co-occurrence would increase the risk of mortality in patients with breast cancer, and whether antidepressant treatment would reduce the same.

Methods: Data were retrieved from the database of the Korean National Health Insurance Service. Of 145,251 patients diagnosed with breast cancer between 2007 and 2014, 20,870 patients diagnosed with depression or anxiety disorder one year before breast cancer diagnosis were excluded.

Quantitative dynamic contrast-enhanced MR imaging shows widespread blood-brain barrier disruption in mild traumatic brain injury patients with post-concussion syndrome.

Objectives: To explore the utility of dynamic contrast-enhanced (DCE) MR imaging for quantitative analysis of blood-brain barrier disruption in mild traumatic brain injury (mTBI) patients with post-concussion syndrome (PCS).

Methods: Forty-four consecutive patients with PCS after mTBI and 32 controls were included in this retrospective study. K and v from DCE MR imaging were analyzed at contrast-enhancing lesions, T2 hyperintense white matter (WM) lesions, normal-appearing white matter (NAWM), and predilection sites for diffuse axonal injury (Location).

Development of second primary cancer in Korean breast cancer survivors.

Purpose: Breast cancer survivors have slightly increased the risk of second primary cancers. Breast, colon, uterine, and ovarian cancers are common secondary cancers in breast cancer survivors. In this study, we assessed the development of second primary cancers of breast cancer survivors in Korea.

Use of All-polyethylene Tibial Components in Unicompartmental Knee Arthroplasty Increases the Risk of Early Failure.

All-polyethylene (all-poly) tibial designs in primary total knee arthroplasty (TKA) have been reconsidered with excellent clinical outcomes, survivorship, and cost-effectiveness. However, whether all-poly tibial components provided comparable results to metal-backed modular components during unicompartmental knee arthroplasty (UKA) remains unclear. This study compared the clinical outcomes and prevalence of early failure between all-poly and metal-backed modular components in UKA.

Treatment of comminuted proximal humeral fractures using locking plate with strut allograft.

Background: This study compared the radiologic outcome of fixation using locking plate only with fixation using locking plate with an endosteal strut allograft in the treatment of comminuted proximal humeral fracture.

Methods: Among 52 patients with comminuted proximal humeral fracture, 32 patients underwent fixation with locking plate only, and 20 patients underwent fixation using locking plate with an endosteal strut allograft. The strut allograft was inserted into the intramedullary cavity of the humerus to support the humeral head and fixed with the locking plate.
