Percutaneous ultrasound-guided A1 pulley release utilizing a modified 20-gauge spinal needle.

Background: Trigger finger is a common cause of hand pain. Though multiple techniques for percutaneous A1 pulley release have been described in the literature, there is a continued need for safe and effective techniques using inexpensive, familiar, and commonly found instruments. This study evaluated outcomes of percutaneous A1 pulley release performed using a novel technique with a modified 20-gauge spinal needle and ultrasound guidance, with follow-up outcomes at least 6 months after the procedure.

Hepatic Adaptations to a High Fat Diet in the MRL Mouse Strain are Associated with an Inefficient Oxidative Phosphorylation System.

The MRL mice are resistant to a 12-week high fat diet (HFD) feeding protocol, with the proximal cause being an increased basal pAMPK expression in the skeletal muscle. Here, we test if this lack of pathology extends to the liver at both the tissue and cellular levels and its correlation to pAMPK levels. MRL and B6 mice were subjected to 12 weeks of diet intervention and tissues were either fixed for histology or snap-frozen for further processing (n= 3-6, per group).

Ulnar nerve injury after a comminuted fracture of the humeral shaft from a high-velocity accident: a case report.

Introduction: Injury to the ulnar nerve following humerus shaft fracture is a very rare entity because the ulnar nerve is well protected from the bone by muscle and soft tissue, and thus remains unaffected in these fractures. We report what is, to the best of our knowledge, the first case of ulnar nerve injury due to a comminuted humeral shaft fracture. The injury manifested and was diagnosed the day after a high-velocity accident.
