Stress radiographs are useful in determining the amount of ligamentous laxity present following trauma. The results may be helpful in determining diagnosis, surgical indications, and the type and timing of rehabilitation. Some techniques for obtaining stress radiographs involve specific patient positioning or manually applied force; others require use of a particular testing device. Stress radi...

The classification of anteroposterior compression (APC) injury type is based on using static radiographs, stress radiographs are known as a useful adjunct in classifying type of APC pelvic injuries. According to a recent article, the intraoperative stress examination has led to a change in the treatment plan in more than 25% of patients on 22 patients presumed APC type I (symphyseal diastasis <...

Instability of the subtalar joint can follow inversion stress injuries to the lateral ankle and hindfoot. Ligaments involved in the injury include the calcaneofibular, lateral talocalcaneal, cervical, interosseous talocalcaneal, or a combination. Although the problem most often occurs in conjunction with lateral ankle instability, it may be an isolated problem and it is not corrected equally we...

BACKGROUND The amount of medial compartment opening for medial knee injuries determined by valgus stress radiography has not been well documented. The purpose of this study was to develop clinical guidelines for diagnosing medial knee injuries using valgus stress radiography. HYPOTHESIS Measurements of medial compartment gapping can accurately differentiate between normal and injured medial s...

The medial collateral ligament is the most commonly injured knee ligament. Valgus stress radiographs are reported to be an effective way to quantify the medial compartment opening. However, most of the techniques require the presence of a physician in the radiograph room to apply a manual valgus stress force, and can only be performed in 1 knee at a time. These techniques, although extremely ef...

Aim: To determine how accurately pre-operative stress radiographs predict the final outcome in adolescent idiopathic scoliosis surgery. Methods: Records of 20 patients were reviewed retrospectively. Pre-operative correction was measured by comparing the initial Cobb angle of the main structural curves on plain standing radiographs to values measured at corresponding levels after correction on t...

Background: We sought to characterize humeral-sided radiographic changes at a minimum of 2 years after reverseshoulder arthroplasty (RSA) to determine their association with specific implantation techniques.Methods: The immediate and most recent postoperative anteroposterior radiographs of 120 shoulders with primary RSAand a minimum of 2-years of radiographic follow-up were an...
