Introduction: Higher case volumes correlate with improved outcomes in total joint arthroplasty surgery. The purpose of this study was to understand the effect of adult reconstruction fellowship training on reported case volume in a contemporary cohort of orthopaedic surgeons.
Methods: The Accreditation Council for Graduate Medical Education provided case logs for orthopaedic surgery residents and adult reconstructive orthopaedic fellows from 2017 to 2018 to 2020 to 2021. Reported case volumes for total joint arthroplasty surgeries were compared using Student t tests.
Results: One hundred eighty-three adult reconstructive orthopaedic fellows and 3,000 orthopaedic surgery residents were included. Residents reported more total hip arthroplasty cases (98.9 ± 30 to 106.1 ± 33, 7.3% increase, P < 0.05) and total knee arthroplasty cases (126.0 ± 41 to 136.5 ± 44, 8.3% increase, P < 0.05) over the study period. On average, fellows reported 439.6 total cases: primary total knee arthroplasty, 164.9 cases (37.5%); primary total hip arthroplasty, 146.8 cases (33.4%); revision total knee arthroplasty, 35.2 cases (8.0%); revision total hip arthroplasty, 33.0 cases (7.5%); unicompartmental knee arthroplasty, 4.4 cases (1.0%); and other, 55.0 cases (12.5%). Overall, adult reconstructive orthopaedic fellowship reported between 1.7- and 2.0-fold more joint arthroplasty cases during 1 year of fellowship training than 5 years of residency ( P < 0.001).
Discussion: Adult reconstructive orthopaedic fellowship training provides notable exposure to additional cases after residency training. The results from this study may inform prospective applicants on the effect of fellowship training in total joint arthroplasty and help establish benchmarks in case volume for independent practice.

Purpose: This study aimed to evaluate the dental and skeletal stability one year after Miniscrew-Assisted Rapid Palatal Expansion (MARPE) by using 3D image data.
Methods: Patients with transverse maxillary deficiency from the age of 16 onwards were enrolled consecutively in this prospective longitudinal cohort study. The MARPE appliance was digitally and individually designed and fabricated.

Background: Mild Behavioral Impairment (MBI) is the onset of sustained neuropsychiatric symptoms that are considered as a possible precursor to neurodegenerative conditions, especially dementia. The concept of MBI recognizes that behavioral changes may be an early sign of brain changes due to neurodegeneration. Very recent research has shown behavioral changes in MBI might be linked to changes in brain structure, including cortical thickness.

Background: Dementia criteria require not only memory impairment, but additional impairment in at least one other cognitive domain, like visuospatial functioning. Cognitive measures assessing visuospatial function often involve drawing shapes. While these measures have proven reliable and valid in developed countries, their use in Low and Middle-income Countries (LMICs) is challenging due to cultural differences and low literacy.

Aseptic loosening (AL) of artificial hip joints is the most common complication following hip replacement surgery. A total of eight patients diagnosed with AL following total hip arthroplasty (THA) undergoing total hip replacement and eight control patients diagnosed with avascular necrosis of femoral head (ANFH) or femoral neck fracture undergoing THA were enrolled. The samples of the AL group were from synovial tissue surrounding the lining/head/neck of the prosthesis, and the samples of the control group were from the synovium in the joint cavity.

This case presents a rare and aggressive manifestation of malignant melanoma, initially presenting as a chest wall swelling in a young male with a history of trauma and subsequent management for hemothorax and pyothorax. The complexity of this case lies in its atypical presentation and the challenges posed in diagnosis and treatment. A 30-year-old gentleman presented to the general surgery clinic with a chief complaint of swelling on the right side of his chest, persisting for two months following a traumatic fall, which later resulted in hemothorax and prothorax required drainage and eventually ended up developing a swelling requiring further investigations.
