0steoarthritis (OA) is a slowly-progressive degenerative joint disease characterized by a loss of joint cartilage and the subsequent exposure of subchondral bone (1). This eventually results in a self-perpetuating insidious disorder characterized by joint pain. New bone formation occurs in response to the chronic inflammation, and local tissue damage in an attempt to limit both movement and pai...

Hallux rigidus (HR) is the limitation of motion at the first metatarsophalangeal (MTP) joint, most commonly secondary to degenerative arthritis. Surgical options for treating HR include 2 general categories: joint salvage and joint destruction. A hybrid of techniques from the 2 categories has emerged: cartilage resurfacing, interpositional arthroplasty, and arthrodiastasis. These procedures add...

In the presence of joint space narrowing, it is important to differentiate inflammatory from degenerative conditions. Joint inflammation is characterized by bone erosions, osteopenia, soft-tissue swelling, and uniform joint space loss. Inflammation of a single joint should raise concern for infection. Multiple joint inflammation in a proximal distribution in the hands or feet without bone proli...

BACKGROUND Few studies have evaluated the effect of existing articular cartilage damage and sex on joint space measurements after isolated degenerative medial meniscus tears. PURPOSE To determine what factors affected joint space width and narrowing in patients after removal of isolated degenerative medial meniscus tears. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A total of...

common cause of degenerative joint disease (DJD) in dogs, is a chronic, progressive, noninfectious joint disorder that leads to degeneration of articular cartilage and proliferative changes. Damage to articular cartilage may result from abnormal stresses that disrupt the normal articular surface, in turn leading to joint instability. Consequently, the normal wear pattern as well as the turnover...

Arthropathy is a frequent and serious complication of repeated joint bleeding in patients with hemophilia, resulting in pain, deformity, and disability. Although the pathogenesis of hemophilic arthropathy has not been fully elucidated, it appears to have similarities with the degenerative joint damage that occurs in osteoarthritis and the inflammatory processes associated with rheumatoid arthri...

An acromioclavicular joint cyst is an uncommonly reported condition, which seems to result from a massive rotator cuff tear and degenerative osteoarthritis of the acromioclavicular joint. We present the case of an 81-year-old man affected by an acromioclavicular joint cyst, associated to a massive rotator cuff tear, proximal migration of the humeral head and osteoarthritis of the gleno-humeral ...

background:  sternocostoclavicular joint (sccj) swelling is an underdiagnosed, albeit important entity in clinical practice. the present study was conducted in order to identify the incidence and common causes of this entity.  methods:  patients presenting to the orthopaedic clinic with a swelling of the sternocostoclavicular joint, during the study period of two years were included, and detail...

Successful deformity correction utilizing first metatarsophalangeal (MTP) fusion for hallux valgus with concomitant degenerative changes of the MTP joint is well documented. Currently, there limited discussion in literature focusing on triplanar arthrodesis. Presented a novel approach triplane and biplanar locked plating system.

Temporomandibular joint (TMJ) disorders have complex and sometimes controversial etiologies. Also, under similar circumstances, one person's TMJ may appear to deteriorate, while another's does not. However, once degenerative changes start in the TMJ, this pathology can be crippling, leading to a variety of morphological and functional deformities. Primarily, TMJ disorders have a non-inflammator...
