Ulnar Nerve Palsy as COVID-19 Sequelae in 3 Patients.

The pathophysiology and treatment of COVID-19 have been at the forefront of medical research this past year. While great strides have been made in our knowledge of the disease, there is still much that is unknown. More than one-third of patients with COVID-19 present with symptoms involving the nervous system.

The Cutting Edge: Surface Texture Analysis following Resection of Nerve Stumps Using Various Instruments.

Background: Preparation of nerve ends is an essential part of nerve repair surgery. Multiple instruments have been described for this purpose; however, no consensus exists regarding which is the least traumatic for tissue handling. We believe that various instruments used for nerve-end excision will lead to different surface roughness.

Selective versus nonselective embolization versus no embolization in pelvic trauma: A multicenter retrospective cohort study.

Background: Traumatic hemorrhage from pelvic fractures is a significant challenge, and angioembolization has become standard. Optimal treatment is undefined in two clinical scenarios. The first is in the presence of a negative angiogram.

Percutaneous freezing of sensory nerves prior to total knee arthroplasty.

Background: Total knee arthroplasty (TKA) is a common procedure resulting in significant post-operative pain. Percutaneous cryoneurolysis targeting the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve could relieve post-operative knee pain by temporarily blocking sensory nerve conduction.

Methods: A retrospective chart review of 100 patients who underwent TKA was conducted to assess the value of adding perioperative cryoneurolysis to a multimodal pain management program.

Does Insurance Status Affect the Management of Acute Clavicle Fractures?

Objectives: To evaluate whether insurance is an unrecognized factor that plays a role in determining whether a patient receives surgery.

Methods: A retrospective cross-sectional analysis was performed using the Healthcare Cost and Utilization Project data for Florida in the year 2010. Discharge level data from emergency departments and ambulatory surgery settings were used to identify clavicle fractures by International Classification of Diseases 9 codes 81,000, 81,002, and 81,003.

Influence of prosthetic design on squeaking after ceramic-on-ceramic total hip arthroplasty.

Squeaky ceramic-on-ceramic (COC) total hips have received much recent publicity, and implant design may be implicated. We reviewed 270 consecutive COC total hip arthroplasties in 233 patients comparing 4 implant combinations representing 4 manufacturers. A cohort (n = 45) of Stryker Trident acetabular cups paired with Stryker Accolade femoral stems showed a dramatically higher incidence of "problem squeaking"--defined as always audible to others and occurring at least once per week--with a 35.
