BACKGROUND Medial elbow distraction during pitching as the primary mechanism contributing to adaptations in ulnar collateral ligament (UCL) appearance during magnetic resonance imaging (MRI) evaluation has not been established. HYPOTHESIS Uninjured high school-aged pitchers with unilateral adaptations of the UCL exhibit a higher peak internal elbow adduction moment than those without UCL adap...

Ulnar collateral ligament insufficiency has been shown to result in changes in contact pressure and contact area in the posteromedial elbow. This study used new digital technology to assess the effect of a complete ulnar collateral ligament tear on ulnohumeral contact area, contact pressure, and valgus laxity throughout the throwing motion. Nine elbow cadaveric specimens were tested at 90° and ...

Most injuries to the medial collateral ligament (MCL) heal well after conservative treatment. We have identified a subgroup of injuries to the deep portion of the MCL which is refractory to conservative treatment and causes persistant symptoms. They usually occur in high-level football players and may require surgical repair. We describe a consecutive series of 17 men with a mean age of 29 year...

The knee joint The knee joint is a hinge type joint made up of the thigh bone (femur) and the shin bone (tibia). The knee joint has ligaments on the inside and the outside of the joint, (medial collateral ligament and lateral collateral ligament) and ligaments inside the joint itself, (anterior cruciate and posterior cruciate ligament). The joint surfaces are covered in cartilage and the cartil...

The authors report the case of a 38-year-old male who presented to the accident and emergency department with a locked knee after falling from a height. The knee was locked at 35° of flexion without any signs of instability in clinical examination. The patient was operated within 6 h from injury. During arthroscopy bucket-handle tears of both medial and lateral menisci were found. The bucket-ha...

BACKGROUND Overuse injuries to the elbow in the throwing athlete are common. Ulnar collateral ligament reconstruction (UCLR), commonly known as Tommy John surgery, is performed on both recreational and high-level athletes. There is no current literature regarding the incidence and demographic distribution of this surgical procedure in relation to patient age, location within the Unites States, ...

OBJECTIVES Digital infrared thermographic imaging (DITI) has been used widely for various inflammatory diseases, circulatory diseases, skin diseases, musculoskeletal diseases and cancers. In cases of ligament injury, obviously the temperature of the damaged area increases due to local inflammation; however, whether the temperature also increases due to DITI has not been determined. The purpose ...

Approaches to management of combined anterior cruciate ligament (ACL) and high-grade medial collateral ligament (MCL) injuries remain controversial. Some studies suggest that with grade III MCL injuries, patients may benefit from concurrent MCL reconstruction to restore stability and prevent increased stress on the ACL graft. We present a technique for simultaneous ACL/MCL reconstructions using...

UNLABELLED Boden et al. suggested syndesmosis fixation was not necessary in distal pronation external rotation (PER) ankle fractures if rigid bimalleolar fracture fixation is achieved and was not necessary with deltoid ligament injury if the fibular fracture is no higher than 4.5 cm of the tibiotalar joint. We asked whether height of the fibular fracture with or without medial stability predict...
