Anatomical insights into medial-sided talar dome osteochondral lesions: a comparative analysis of unilateral and bilateral cases and healthy controls using MRI measurements.

Background: The etiology of medial-sided talar osteochondral lesions (OCLs) remains insufficiently understood.

Purpose: To identify anatomical risk factors contributing to the development of unilateral or bilateral OCL of the talus on the medial side, utilizing morphological parameters derived from magnetic resonance imaging (MRI).

Material And Methods: In this retrospective study, 24 ankle MRI scans from 12 patients exhibiting bilateral OCLs of the talar dome on the medial side, 24 ankle MRIs from 24 patients with unilateral medial-sided OCLs, and 24 healthy controls matched for age, sex, and side within each group were analyzed.

Controversies in Artificial Intelligence in Neurosurgery.

Artificial intelligence (AI) has evolved from science fiction to a technology infiltrating everyday life. In neurosurgery, clinicians and researchers are exploring ways to implement this powerful tool to improve the safety and efficiency of the perioperative process. Current applications include preoperative diagnosis, intraoperative detection and recommendations, and technical skills assessment and feedback.

Axillary lymph node dissection is not required for breast cancer patients with minimal axillary residual disease after neoadjuvant chemotherapy.

Background: Sentinel lymph node biopsy (SLNB) is widely used in patients who receive neoadjuvant chemotherapy (NAC). Still, axillary lymph node dissection (ALND) is recommended for patients with any axillary residual disease after NAC. The necessity of ALND in patients with minimal axillary disease is unclear.
