Percutaneous Surgery for Mild to Moderate Hallux Valgus.

Patients who undergo percutaneous chevron-Akin osteotomies have less pain at follow-up, greater correction of hallux valgus angle, and a shorter operation time compared with open osteotomies. Stable fixation of the chevron osteotomy allows early full weight bearing and mobilization of the first metatarsophalangeal joint. This article describes the surgery technique, including reduction of the first metatarsal head after translation, accurate positioning of the proximal first metatarsal fixation screw, and removal of the dorsomedial prominence of the first metatarsal head.

Preoperative Femoral Nerve Block for Hip Arthroscopy: A Randomized, Triple-Masked Controlled Trial.

Background: Arthroscopy has become a standard method of treatment for a variety of intra-articular hip disorders. While most arthroscopic hip procedures are performed as outpatient surgeries, patients can still experience significant postoperative pain and opioid-associated side effects.

Purpose: The potential benefits of a preoperative femoral nerve block (FNB) in hip arthroscopy were explored in a previous retrospective review.

Preoperative femoral nerve block in hip arthroscopic surgery: a retrospective review of 108 consecutive cases.

Background: The utility of a femoral nerve block as an adjunct for pain management has been recognized for various surgical techniques but has yet to be examined in the preoperative setting as an adjunct to general anesthesia for improved postoperative pain control in hip arthroscopic surgery.

Purpose: To evaluate the safety and efficacy of a preoperative femoral nerve block for postoperative pain control in patients undergoing hip arthroscopic surgery.

Study Design: Cohort study; Level of evidence, 3.

Initiation of a zebrafish blastula cell line on rainbow trout stromal cells and subsequent development under feeder-free conditions into a cell line, ZEB2J.

A continuous cell line, ZEB2, was developed from zebrafish blastula-stage embryos expressing enhanced green fluorescent protein (GFP). Originally the rainbow trout spleen cell line, RTS34st, was used as feeders to initiate and maintain the cells through several passages. ZEB2 was then grown for 2 years without feeders in L-15 with 15% fetal bovine serum (FBS) for 120 population doublings.
