Medial collateral ligament injuries are common and are often associated with concomitant ligamentous, meniscus, and cartilage injuries. Orthopedic surgeons should be familiar with the outcomes of nonoperative and operative treatment of isolated and combined grade I, II, and III injuries. Special attention should be paid to identifying involvement of the posterior oblique ligament and capsule; l...

DOWN syndrome (DS) is the most common chromosomal disorder, occurring in 1 of every 600–800 births. It is characterized by mental retardation, as well as craniofacial, upper airway, cardiovascular, and gastrointestinal anomalies. One manifestation of DS relevant to anesthesiologists is upper cervical spine instability produced by ligamentous laxity, skeletal anomalies, or both. This instability...

Clinical and radiographic evaluation of an infant boy and his father revealed findings suggesting a new variant of spondylometaphyseal dysplasia with an apparently autosomal dominant mode of inheritance. The main clinical findings included short stature and marked ligamentous laxity in the infant. X-ray findings included severe and peculiar multiple metaphyseal involvement and striking vertebra...

Ten children who had clinically stable hips at birth were radiographed at one month because they had factors predisposing to hip dislocation. In all cases one or both hips gave rise to a suspicion of dysplasia, though clinical abnormalities were slow to appear. Four of these hips subsequently dislocated. We believe that infants with late presentation of acetabular dysplasia and clinical abnorma...

We reviewed 41 knees after arthroscopic lateral release for recurrent dislocation of the patella at a mean follow-up of four years, and graded the results according to the criteria of Crosby and Insall (1976). There were no dislocations after operation in 28 knees (68%); the less satisfactory results were in patients with subluxation of the patella on extension of the knee and those with genera...

Background: Atlantoaxial subluxation occurs when there is misalignment of the atlantoaxial joint. Several etiologies confer increased risk in children, including neck trauma, inflammation, infection, or inherent ligamentous laxity cervical spine.
 Methods: A case study was performed. Demographics and clinical data were reviewed for etiology, imaging techniques, treatment, clinic outcomes.&...

The Americanjoumal a/Occupational Therapy T he proXimal interphalangeal (PIP) joint is particularly susceptible to acute ligamentous injury, and such an injury can result in swelling without ligament laXity, collateral ligament laXity and disruption, or a partial or complete avulsion of the volar plate with or without bony involvement. Many articles have been written about methods for treatment...

Arthrosis following rupture of the anterior cruciate ligament has been analysed in two series. The first series was derived from a review of 150 cases of reconstruction of the anterior cruciate ligament with a follow-up of 3 years or more. Arthrosis was seen to have developed in 13.3%. The second series was concerned with 64 cases of unilateral arthrosis treated by upper tibial valgus osteotomy...

Instrumented arthrometry is an important treatment adjunct for anterior cruciate ligament (ACL)-deficient patients before and after patellar tendon reconstruction, which provides objectivity to other subjective outcome measures and allows for accurate comparison between studies. Increasing numbers of clinical reports are using arthrometry to objectively report anterior displacements. Arthrometr...
