Posterolateral knee injuries can be very debilitating. It is important to understand the complex anatomy and pertinent diagnostic tests to properly treat posterolateral knee injuries. The fibular collateral ligament, popliteus tendon, and the popliteofibular ligament are the main static stabilizers against abnormal varus and posterolateral translational moments. Important radiographic imaging s...

Of eithty-six patients with collateral ligament instability of the metacarpophalangeal joint of the thumb, sixty-six (77 per cent) had ulnar and twenty (23 per cent) had radial instability, while in addition twenty-four had fractures and twenty-nine had volar subluxation of the proximal phalanx. Of the sixty-nine patients operated on, sixty-five had an abnormality of the ulnar or radial collate...

PURPOSE The role of the posterior bundle of the medial collateral ligament in stability of the elbow remains poorly defined. The purpose of this study was to determine the effect of sectioning the posterior bundle of the medial collateral ligament on the stability of the elbow. METHODS Varus and valgus gravity-loaded passive motion and simulated active vertical motion were performed on 11 cad...

We conducted a prospective study to evaluate bone bruises, or trabecular microfractures, associated with isolated medial collateral ligament injuries. Magnetic resonance imaging was performed on 65 patients with isolated medial collateral ligament injuries determined by physical examination and imaging studies. Of these 65 patients, 29 (45%) had associated trabecular microfractures. Follow-up i...

Medical elbow ligament sprains in athletics can be traumatic and disabling. In this case report, we outline the effect of a prototype functional elbow brace on joint stability in a female collegiate javelin thrower with an ulnar collateral ligament sprain. A valgus force to both elbows was applied using graded stress radiography (Telos GA-II/E stress device) at 0, 5, 10, and 15 kiloPascals (kPa...

The medial collateral ligament (MCL) is the most commonly injured ligament of the knee joint. Proximal superficial medial collateral ligament (MCL) tears occur more frequently than do distal ones. Isolated avulsion of deep MCL is not well described in literature. We report a 61-year-old man with a valgus injury of his left knee joint after a MVA. Radiological and magnetic resonance imaging of t...

BACKGROUND Ulnar collateral ligament reconstruction is commonly performed in major league pitchers, but little is known about pitching performance after a return to major league play. HYPOTHESIS Pitching performance after ulnar collateral ligament reconstruction returns to baseline by the second season after surgery. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS Dat...

BACKGROUND Ulnar collateral ligament injury and its subsequent surgical reconstruction are some of the most common issues among Major League Baseball (MLB) players. PURPOSE/HYPOTHESIS The purpose of this study was to determine factors predictive of ulnar collateral ligament reconstruction (UCLR) among MLB pitchers. The hypothesis was that pitchers who underwent UCLR would have higher preinjur...

Introduction: Injury to the posterolateral corner (PLC) of knee often requires surgical reconstruction. There remains no consensus on treatment for PLC injury, and, therefore, it is imperative have a reproducible injury model improve general knowledge injuries. A novel cadaveric isolated proposed and evaluated using radiographic parameters as well gross dissection. Material methods: All protoco...

INTRODUCTION Fracture dislocations of the elbow appear extremely complex. Identification of the basic injury patterns can facilitate management. CASE PRESENTATION A 38-year-old male motor-vehicle driver who fell on his right elbow after an accident was suffering from posterior dislocation of the elbow, without coronoid fracture, and with fracture of the radial head and olecranon, and medial c...
