The ulnar collateral ligament stabilizes the elbow joint from valgus stress associated with the throwing motion. During baseball pitching, this ligament is subjected to tremendous stress and injury if the force on the ulnar collateral ligament during pitching exceeds the physiological limits of the ligament. Injuries to the throwing elbow in baseball pitchers result in significant time loss and...

Open dislocation of the proximal interphalangeal (PIP) joint is relatively rare. We report a case of a 32-year-old man who had open dislocation of the PIP joint of the little finger while playing American football. He had a history of chronic radial collateral ligament injury. We reconstructed the radial collateral ligament with a half-slip of the flexor digitorum superficialis tendon.

The current study analyzed changes in anterior cruciate ligament (ACL) and lateral collateral ligament stress as a result of mechanical varus. In an exploratory pilot study, progressive mechanical varus was introduced to a male finite element model of the lower limb at different knee flexion angles. Nine situations were analyzed (combinations of 0°, 30°, and 60° knee flexion and 0°, 5°, and 10°...

Seventy-one consecutive patients with posterolateral knee injuries had clinical stability testing abnormalities documented prospectively. We compared these findings with the incidence and patterns of their injuries documented at surgery. An abnormal reverse pivot shift test was associated with injury to the fibular collateral ligament (P = 0.01), popliteal components (P = 0.01), and midthird la...

BACKGROUND Ulnar collateral ligament reconstruction (UCLR) is commonly performed in Major League Baseball (MLB) pitchers, but little is known about the preoperative pitch type and velocity characteristics of pitchers who go on to undergo UCLR. HYPOTHESIS Pitchers who required UCLR have thrown a greater percentage of fastballs and have greater pitch velocities compared with age-matched control...

The medial collateral ligament (MCL) is the most frequently injured ligament in the knee, with mild-to-moderate tears often going unreported to physicians. Medial collateral ligament injuries can result from both contact and noncontact sporting activities. The mainstay of treatment is nonoperative; however, operative management of symptomatic grade II and grade III injuries is considered when l...

The medial collateral ligament (MCL) is the most commonly injured knee ligament.1-3 The mechanism of injury is typically a contact valgus load on the lateral side of the knee with the foot planted; however, noncontact external rotation valgus injuries are also common. Medial collateral ligament failure can occur alone or in combination with cruciate and meniscal injury. Fetto and Marshall4 foun...

Medial collateral ligament (MCL)injury, is one of the most common ligament injuries of the knee,mostly results from a valgus force.Restoration of function and going back to the pre-injury level of function is the aim of treatment in ligament injuries of the knee. There are multiple soft tissue structures in medial side that play an important role in connection with each other to retain medial s...
