Grisel syndrome is a rare, non-traumatic atlanto-axial subluxation associated with an inflammatory or infectious process in the upper neck. According to the two-hit hypothesis, which is widely accepted for the pathogenesis of Grisel syndrome, preexisting ligamentous laxity of the atlanto-axial joint is regarded as the first hit. An inflammatory or infectious process of the atlanto-axial joint a...

Ligamentous injuries of the lower limb are a common entity sustained during sports activities and military training. Magnetic resonance (MR) imaging of the knee and ankle is playing an increasingly important role in the detection, diagnosis and prognosis of these injuries and their associated complications. MR imaging with its exquisite soft tissue contrast resolution and multiplanar capability...

A common finding in progressive osteoarthritis of the carpometacarpal joint of the thumb is ligamentous laxity. In patients with Ehlers-Danlos syndrome, which is a disorder characterized by generalized ligamentous laxity, splinting and arthrodesis have been recommended because of the random results achieved by other reconstructive procedures. We report a patient with thumb carpometacarpal joint...

BACKGROUND To identify and characterize the concomitant ligamentous and meniscal injuries in floating knee. METHODS A total of 37 cases of floating knee were enrolled. Arthroscopic or open surgical examination of the knee, Lachman test, posterior drawer's test, and varus and valgus stress tests under anesthesia were carried out to determine the incidence of knee injury. RESULTS Through arth...

OBJECTIVES To investigate if ligamentous laxity increases seasonal incidence of injury in male first division club rugby players, and to determine if strength protects against injury in hypermobile and tight players. METHODS Fifty one male first division club rugby players were examined for ligamentous laxity using the Beighton-Horan assessment and graded with an overall laxity score ranging ...

BACKGROUND Nonoperative treatment of posterolateral knee injuries tends to yield poor results. In patients with chronic posterolateral knee injuries, failure to correct genu varus alignment will often result in failure of the posterolateral knee repair or reconstruction. PURPOSE To prospectively assess the functional outcomes of patients with combined grade 3 posterolateral instability and ge...

BACKGROUND Medial patellofemoral ligament (MPFL) reconstruction has become one of the most common and widely used procedures to regain stability among patients with recurrent lateral patellar dislocation. While recent studies demonstrated low recurrence rates, improved patient-reported outcome measures, and a high rate of return to sports, limited literature explored its effectiveness as an iso...
