Background: Although it has been proposed that in mid-stage ankle osteoarthritis, the subtalar joint can compensate for deformities above the ankle joint, the evidence is weak. We thus investigated subtalar joint alignment in different stages of ankle osteoarthritis using weightbearing computed tomography (CT) scans Monteggia fractures are proximal 1/3rd ulna fractures with associate... d radial head dislocations. The Bado classification is used to classify these injuries with respect to the direction of the radial head dislocation with type I being an anterior radial head dislocation, type II being a posterior dislocation, and type III being a lateral dislocation Displaced femoral neck fractures in young patients have created many... treatment controversies that are ongoing in the literature due to devastating consequences of poor outcomes, including nonunion and osteonecrosis of the femoral head.

Scapholunate advanced collapse (SLAC), commonly known as SLAC wrist, refers to a pattern of wrist malalignment that has been attributed to post-traumatic or spontaneous osteoarthritis of the wrist. It is a complication that can occur with undiagnosed or untreated scapholunate dissociation.. It is essentially the same sequela of wrist injury causing scaphoid nonunion as seen in scaphoid. Scaphotrapeziotrapezoidal arthritis. Scaphotrapeziotrapezoidal (STT or triscaphe joint) arthritis is common, occurring in ~40% of wrist radiographs. It is typically degenerative (i.e. osteoarthritis) affecting the triscaphe articulation and presents with radial-sided wrist pain in patients over 50 years 1,2

Walch Classification: Adding Two New Glenoid Types. The Walch classification is the most frequently utilized method for defining glenohumeral pathology in osteoarthritis. Adding two new glenoid types increases inter-rater reliability and offers a more reproducible system A review of 27 fractures of the acromion process during a 15-year period revealed five distinct types that were classified into three groups. Stress fractures are rare, do not result from acute trauma, and gain little benefit from nonoperative treatment. Type I fractures are minimally displaced. Typ Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage that cushions the ends of the bones wears down over time. Although osteoarthritis can damage any joint, the disorder most commonly affects joints in your hands, knees, hips and spine

Osteoarthritis is a disorder of synovial joints, which occurs when damage triggers repair processes leading to structural changes within a joint. Joint damage may occur through repeated excessive loading and stress of a joint over time, or by injury. Any synovial joint can be involved — most commonly the knees, hips, and small joints of the hand The Outerbridge classification is a grading system for joint cartilage breakdown in the patella. Normal joint cartilage of femur (below) and patella (above) in the knee joint. Grade 0 on the Outerbridge scale. Grade I - softening of the patellar cartilage, which can be dimpled with a rounded probe. Grade III damage of the patella on the same. Patellofemoral arthritis occurs when the articular cartilage along the trochlear groove and on the underside of the patella wears down and becomes inflamed. When cartilage wears away, it becomes frayed and, when the wear is severe, the underlying bone may become exposed. Moving the bones along this rough surface may be painful

Crawford's classification of CPT (1986) identifies four types of CPT all with anterolateral bowing of the tibia. 5 In type I, the medullary canal is preserved and cortical thickening at the apex of the deformity might be observed; patients with this type usually have a good prognosis; some may not even have a fracture.

Most septic joints develop as a result of hematogenous seeding of the vascular synovial membrane due to a bacteremic episode (86, 113).Although a rare cause, acute septic arthritis may also occur as a result of joint aspiration or local corticosteroid joint injection (74, 86).In addition, bacterial arthritis may arise secondary to penetrating trauma (such as human or.

Women and men are equally likely to develop reactive arthritis in response to foodborne infections. However, men are more likely than are women to develop reactive arthritis in response to sexually transmitted bacteria. Hereditary factors Septic arthritis is also commonly referred to as bacterial or infectious arthritis. Septic arthritis is an intensely painful infection in a joint. Bacteria, viruses, and fungi may invade the joint through various routes that cause inflammation of the synovial membrane. With the onset of inflammation, cytokines and proteases are released, thus resulting in potential joint destruction
