Effect of Forearm Posture on the Elbow Varus Torque Generated by the Flexor Pronator Muscles: Implications for the Ulnar Collateral Ligament
نویسندگان
چکیده
Previous work has demonstrated that the flexor pronator muscles of the arm (Flexor Digitorum Superficialis, Flexor Carpi Radialis, Flexor Carpi Ulnaris, and Pronator Teres) are primary contributors to varus torques that counter applied valgus torques [3, 5]. These muscles originate on the ulnar side of the distal humerus and have been shown to be highly active during pitching [4]. Additionally, experimental work in cadavers has revealed that tension in these muscles relieves stress on the UCL and can protect it from failure [5].

Effects of flexor-pronator muscle loading on valgus stability of the elbow with an intact, stretched, and resected medial ulnar collateral ligament.
BACKGROUND The medial ulnar collateral ligament (MUCL) is an important passive stabilizer to the valgus stresses that athletes experience during overhead throwing motion. However, the role of the flexor-pronator muscles as active stabilizers to valgus stress is not well defined in the literature. The objectives of this study were to quantify the relative contribution of the individual flexor-pr...
متن کاملDynamic contributions of the flexor-pronator mass to elbow valgus stability.
BACKGROUND Previous studies have indicated that the demands placed on the medial ulnar collateral ligament of the elbow when it is subjected to valgus torque during throwing exceed its failure strength, which suggests the necessary dynamic contribution of muscle forces. We hypothesized that the flexor-pronator mass assists the medial ulnar collateral ligament in stabilizing the elbow against va...
متن کاملUltrasonographic assessment of the flexor pronator muscles as a dynamic stabilizer of the elbow against valgus force.
Flexor pronator muscles (FPMs) play a key role in stabilizing the elbow joint against valgus forces. However, no studies have investigated the in vivo kinematics of FPMs against these forces on the elbow. This study aimed to clarify the in vivo contribution of each FPM as a dynamic stabilizer in a clinical situation.Twelve healthy volunteers participated in this study. Verbal informed consent w...
متن کاملCombined surgical treatment for missed rupture of triceps tendon associated with avulsion of the ulnar collateral ligament and flexor-pronator muscle mass
Triceps tendon ruptures are rare injuries. Coexistence of ipsilateral ulnar collateral ligament injury is even rarer. Here, we describe an unusual combination injury to elbow of a 39-year-old male construction worker consisting of triceps tendon rupture, avulsion of elbow ulnar collateral ligament and flexor pronator muscle origin ipsilaterally. A simultaneous repair and reconstruction of all d...
متن کاملNon-anatomical reconstruction of lateral ulnar collateral ligament of the elbow after tumor resection
We present the case of an 80-year-old man with a tumor recurrence on his right arm 6 years after initial treatment. The lateral aspect of the elbow joint, involving overlaying skin, muscles, tendons, joint capsule, lateral collateral ligament complex, the lateral 1/3 of the capitellum, and lateral epicondyle of humerus were excised in the tumor resection. Intraoperative assessment revealed mult...
