A 3-week old Hanoverian foal was presented with bilateral moderate to severe carpal valgus. The deviations were 10 and 14 degrees, respectively for the left and right carpi and orthogonal radiographs of both front limbs highlighted bilateral persistent ulnar remnants. A partial resection of the ulnar remnants and periosteal transection on the disto-lateral aspect of the radius were performed bilaterally under general anesthesia. The valgus deviations began to improve within the first month and the limbs were almost straight (2 degrees for the left and right carpi) 5 1/2 months after surgery. This is the first report of successful surgical correction of bilateral carpal valgus secondary to persistent ulnar remnants in a large breed foal. The combination of partial ulnar remnant resection and radial disto-lateral periosteal transection, detailed in this report, should be considered for treatment of foals with this condition.

The persistence of the median artery in adult life, a remnant of the early brachial artery in the embryonic stage, has been reported in many anatomical and clinical studies. Herein, we aimed to investigate the prevalence and origin of the median artery in cadavers. We examined 53 adult Japanese cadavers and carefully dissected 106 upper limbs, and the arterial systems in the forearms and hands were observed macroscopically.

A 40-year-old patient and a 45-year-old patient presented with chronic dorsal and lateral subluxation of the proximal interphalangeal (PIP) joint of the little finger and underwent surgeries. Through a dorsal approach, the ulnar lateral band was transected and transferred to the radial side through the volar side of the PIP joint. The transferred lateral band and the remnant of the radial collateral ligament were secured with an anchor on the radial side of the proximal phalanx.

Background: Type B ulnar polydactyly is one of the most commonly encountered congenital hand differences and can be treated with ligation or excision. The purpose of this study was to determine what factors families consider in selecting treatment for their child with type B ulnar polydactyly.
Methods: We reviewed treatment outcomes and administered a survey by telephone to parents of children with type B ulnar polydactyly treated at a pediatric hospital between 2015 and 2020.

Purpose: Triceps tendon injuries are rare and often caused by direct trauma to the arm. There are no clear guidelines on the management of these and typically partial tears are treated conservatively whilst full thickness tears are treated with primary surgical repair. We aim to review the literature on the methods for triceps repair and propose a novel surgical technique.
