Radiographic clues to the unstable knee: are findings of trochlear dysplasia on lateral knee radiographs reliable and predictive of patellar dislocation?

Background: Trochlear dysplasia (TD) is a key predisposing risk factor for patellar instability (PI) and lateral patellar dislocation (LPD) injuries. It is useful to understand the reliability of radiographic findings of TD and the accuracy of knee radiographs in diagnosing patients with recent LPD.

Purpose: The purposes of our study are to evaluate the inter-rater reliability of specific radiographic signs of PI and staging of TD between radiologists and orthopedic surgeons, and to identify which findings are associated with recent LPD.

High rate of inappropriate referrals to pediatric orthopedics in an egalitarian healthcare system.

Previous studies have shown relatively high rates of inappropriate referrals to pediatric orthopedic surgery. The purpose of this study was to determine the rate of inappropriate referrals in an egalitarian healthcare system. We reviewed all 400 referrals to our pediatric orthopedic surgery practice over a 2-year period and assessed the appropriateness of each based on the American Academy of Pediatrics guidelines.

Bilateral Crush Injury of the Proximal Tibial Physis in an Adolescent Gymnast: A Case Report.

Case: A thirteen-year-old female gymnast experienced bilateral knee pain after landing from a jump off a vault during a competition. Initial radiographs revealed negative findings, but magnetic resonance imaging demonstrated periphyseal osseous edema of the proximal parts of the tibiae. The patient later developed an anterior physeal bar on the right side, with recurvatum deformity.

Isolated ring finger flexor digitorum profundus entrapment after closed reduction and intramedullary fixation of both-bone forearm fracture.

Flexor tendon entrapment after a pediatric forearm fracture is a rarely reported complication that is often diagnosed late. Flexor tendon entrapment is more frequently reported after distal forearm fractures, and possible etiologies include fibrosis secondary to hemorrhage at the fracture site and simple entrapment of the muscle belly.This article describes a case of ring finger flexor digitorum profundus entrapment in a 12-year-old boy with a closed both-bone forearm fracture that was treated with closed reduction and intramedullary nail fixation.
