Purpose: This case series presents four cases of periprosthetic ulna fractures following Aptis distal radioulnar joint (DRUJ) arthroplasty to elucidate clinical characteristics, contributing factors, management challenges, and short-term outcomes following this rare complication and to propose prevention and optimal treatment strategies.
Methods: We conducted a retrospective review of 239 Aptis DRUJ prostheses implanted between 2012 and 2022 at a single institution. We identified four cases of periprosthetic ulna fractures and assessed demographics, surgical indications, time to fracture, mechanism of injury, radiographic findings, treatment modalities, associated complications, and outcomes.
Purpose: The purpose of this study was to gauge whether patients with preexisting mental health conditions have desirable outcomes when undergoing wide-awake local anesthesia with no tourniquet (WALANT) hand surgery.
Methods: A retrospective review of 133 patients who underwent WALANT surgery by 2 senior authors from August 2019 to October 2020 was performed. Patients were administered a 10-question postoperative survey detailing perioperative pain, experience, and satisfaction concerning their procedure.
Background: Chronic distal biceps tendon ruptures may require tendon graft augmentation secondary to tendon attrition or retraction. The lacertus fibrosus is a local, cost-effective graft that can be used to supplement reconstruction.
Purpose: To compare the biomechanical strength of distal biceps tendon repairs with and without lacertus fibrosus augmentation in a tendon-deficient cadaveric model.
Background: We attempted to evaluate patient satisfaction and overall experience during wide awake, local anesthesia, with no tourniquet (WALANT) hand surgery and quantify surgery-related outcomes.
Methods: We conducted a retrospective analysis of patient demographics, comorbidities, and patient reported outcomes via Single Assessment Numeric Evaluation (SANE) scores collected pre- and postoperatively of patients undergoing WALANT surgery by the 2 participating senior authors. A solution of 1% lidocaine with 1:100,000 epinephrine was used by 1 surgeon, while the other used a 1:1 ratio of 1% lidocaine with 1:100,000 epinephrine and 0.
Purpose: To perform a quantitative anatomic evaluation of the deltoid and trapezius footprints in relation to the lateral clavicle and acromioclavicular (AC) joint capsule to assist in surgical technique of AC joint reconstructions.
Methods: Fourteen fresh-frozen human cadaveric shoulders from 9 donors were analyzed. Meticulous dissection of the deltoid origin and trapezius insertions to the clavicle and AC joint was performed.
Objective: Explore the validity of the Caprini Score in orthopaedic patients with lower-extremity fractures.
Design: Retrospective cohort study.
Setting: Level I trauma academic medical center.
Periprosthetic joint infections are a major cause of morbidity and mortality following total joint arthroplasty. Two-stage arthroplasty, with the use of an antibiotic cement spacer, is an effective means of managing periperiprosthetic joint infections. There is a lack of data relating to the management, prognosis, and clinical outcomes associated with multiple peri-prosthetic joint infections.
View Article and Find Full Text PDFImpaired facial emotion recognition abilities in HIV+ patients are well documented, but little is known about the neural etiology of these difficulties. We examined the relation of facial emotion recognition abilities to regional brain volumes in 44 HIV-positive (HIV+) and 44 HIV-negative control (HC) adults. Volumes of structures implicated in HIV-associated neuropathology and emotion recognition were measured on MRI using an automated segmentation tool.
