Background: Reverse shoulder arthroplasty (RSA) was initially developed for rotator cuff arthropathy but has been expanded to treat comminuted proximal humerus fractures. Few studies have compared RSA for traumatic and degenerative indications. We present the first report of mid-term outcomes of RSA comparing both indications in an Asian population.

- This study compares the 1-year outcomes of endoscopic transforaminal lumbar interbody fusion (E-TLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in patients with specific spinal conditions.
- E-TLIF provided advantages such as shorter surgery time, less blood loss, and a reduced hospital stay compared to MIS-TLIF, while both methods led to similar improvements in pain and functionality after one year.
- No complications occurred in the E-TLIF group, while the MIS-TLIF group experienced minor issues, but both techniques showed successful results without significant differences in long-term outcomes.
Background: This study investigated 1-year clinical and radiological outcomes of biplanar expandable (BE) cages following transforaminal lumbar interbody fusion (TLIF) in an Asian population.
Methods: A retrospective review was conducted of all consecutive patients who underwent TLIF with BE cages performed by 2 fellowship-trained spine surgeons from 2020 to 2021. Inclusion criteria included open or minimally invasive (MIS) TLIF, of up to 3 spinal segments, performed for treatment of degenerative disc disease, spondylolisthesis, or spinal stenosis.
Introduction: Osteoblastoma is a primary benign tumour which commonly presents in the younger population during the second decade of life. However, more aggressive osteoblastomas may present with features of aneurysmal bone cyst, and these can occur at uncommon locations.
Case Presentation: We report the case of a 12-year-old child having an osteoblastoma on the left side of T11 with secondary aneurysmal bone cyst presenting with neurological deficits and myelopathic symptoms.
Background: Surgical treatment for metastatic pathological femur fractures is associated with high mortality. Correct estimation of prognosis helps in determining the palliative value of surgical treatment and informs surgical decision. This study evaluates the risk factors for mortality in these patients who were surgically treated.
