PURPOSE: Excessive flexion at the distal interphalangeal (DIP) joint disrupts the extensor mechanism, leading to mallet finger injuries. The goal of management is to restore active DIP joint extension. We sought to learn which variables (treatment technique, injury type, time to presentation, adherence to treatment) affect clinical outcomes of pediatric mallet finger injuries. METHODS: A retrospective review was performed of patients who presented with mallet finger injuries during 2013 to 2017 at a large pediatric hospital...

Given the appropriate cues, kinematic factors associated with low back injury risk and pain, such as spine flexion, can be avoided. Recent research has demonstrated the potential for tactile sensory information to change movement. In this study an athletic strapping tape was applied bilaterally along the lumbar extensor muscles to provide continuous tactile feedback information during a repeated lifting and lowering task. The presence of the tape resulted in a statistically significant reduction in lumbar spine flexion when compared to a baseline condition in which no tape was present...

The nordic hamstring exercise (NHE) is a dynamic lengthening hamstring exercise that requires trunk and hip muscles activation. Thigh muscles activation, specifically hamstring/quadriceps contractions has been previously examined during NHE. Trunk and hip muscles activity have not been enough studied. The aim of this study was to analyze of hip and trunk muscles activity during NHE. Surface electromyography (EMG) and kinematic data were collected during NHE. Ten healthy men with the age range of 21-36 years performed two sets of two repetitions with downward and upward motions each of NHE...

Blunt trauma to the anterior knee typically results in a contusion or fracture of the patella. Additionally, injury to the extensor mechanism may come from a partial or full disruption of the patellar or quadriceps tendon. A professional baseball player suffered an injury to his knee after he collided with an outfield wall. Acute swelling in the suprapatellar soft tissues concealed a palpable defect, which initially was suspected to be an injury to the quadriceps tendon. Magnetic resonance imaging of the knee revealed an intact extensor mechanism; moreover, a fracture of the subcutaneous fat anterior to the quadriceps tendon was evident and diagnosed as a fat fracture...

PURPOSE: The retention and capture functions of hand can be achieved by the consistent manner work of the extensor and flexor muscles. Therefore, it is important to know variations of the extensor and flexor muscles. METHODS: During an educational dissection, accessory heads of the extensor carpi radialis longus muscle were found on the right side in a Korean cadaver. RESULTS: The extensor carpi radialis longus muscle was originated from the lateral supracondylar ridge of the humerus and trifurcated into three heads as lateral, intermediated, and medial heads...

The myoprotective effects of creatine monohydrate (CR) and whey protein (WP) are equivocal, with the use of proxy measures of muscle damage making interpretation of their effectiveness limited. The purpose of the study was to determine the effects of CR and WP supplementation on muscle damage and recovery following controlled, chemically-induced muscle damage. Degeneration of the extensor digitorum longus (EDL) muscle was induced by bupivacaine in rats supplemented with either CR, WP, or standard rat chow (CON)...

INTRODUCTION: The thorough knowledge of the anatomy of the extensor tendon system of the hand is crucial for clinical examination and detection of tendon injuries. The Juncturae between the EDCII and other extensor tendons presents different incidences, shapes ("r" or "y") and morphologies (Type I, II, III). The EIP does not receive connection. These characteristics may result in variable effects on extensor tendons during active finger movements. The purpose of this study is to investigate and describe a new sign helping diagnosis for injuries or pathologies of EIP and EDC index finger (EDC II), based on a cadaveric dissection and clinical observation...

Extensor tendon ruptures due to volar plating in distal radius fractures have mostly been described in relation with technique failures such as screw prominence and drill penetration. We report the case of a 71-year-old female with a C2 distal radius fracture with severe dorsal metaphyseal comminution. The patient underwent surgical treatment with reduction of the large fragments and fixation with a volar locking plate; the small dorsal metaphyseal nonarticular fragments were not reduced. Six months later, the patient developed extensor digitorum communis (EDC) rupture and extensor indicis proprius (EIP) laceration in coincidence with the dorsal comminution turned into a bony spur...

BACKGROUND: The ability to assess skeletal muscle function and delineate regulatory mechanisms is essential to uncovering therapeutic approaches that preserve functional independence in a disease state. Skeletal muscle provides distinct experimental challenges due to inherent differences across muscle groups, including fiber type and size that may limit experimental approaches. The flexor digitorum brevis (FDB) possesses numerous properties that offer the investigator a high degree of experimental flexibility to address specific hypotheses...

Various flaps are used for skin defects of the dorsal hand and fingers. A sensory flap is not essential, but a thin and good color-matched flap is suitable, and donor site mobility of the flap should be considered. A reverse or free posterior interosseous artery perforator flap is one of the standard flaps. This flap requires no major arterial sacrifice, but direct closure of the donor site is difficult when the width of the flap is >3 cm, and there is also the risk of posterior interosseous nerve injury, especially the motor branch of the extensor carpi ulnaris muscle...

PURPOSE: An increase in the value of the hamstring-to-quadriceps (H/Q) ratio with an increase in angular velocity may effectively prevent injuries of the back of the thigh. Previous studies have found that the conventional H/Q ratio was unaltered along with an increasing angular velocity in females. Therefore, this study aimed to investigate the relationships between the conventional H/Q ratio and angular velocity in a group of female soccer players. METHODS: The study was carried out on a group of 16 female soccer players (age: 20...
