Acute carpal tunnel syndrome caused by pseudogout occurred in a Chinese patient. The radiological findings mimicked those of synovial chondromatosis. Such radiological findings were very unusual. Diagnosis of such conditions may be difficult, since the clinical features may be confused with those of gout and infection. Surgical release is the treatment of choice.

Intra-articular synovial chondromatosis in the hand is rare but should be considered in the differential diagnosis of a swollen, stiff or painful joint. Other possible diagnoses include osteoarthritis, rheumatoid arthritis, gout, trauma and chronic infection, and unless enchondral ossification of loose bodies is seen the diagnosis of synovial chondromatosis may not be made preoperatively. A 69-year-old man with synovial chondromatosis of the metacarpophalangeal joint is reported. The joint was swollen and tender. He had not sustained trauma and there was no evidence of arthritis, involvement of other joints or infection. Complete synovectomy with removal of all loose bodies was successful and his symptoms resolved. Intra-articular synovial chondromatosis is a benign condition, but spontaneous resolution is the exception and surgical synovectomy remains the most effective treatment.

A 56-year-old woman with systemic lupus erythematosus developed septic arthritis and bursitis of the left shoulder due to an atypical mycobacterium, M. xenopi. Plain radiography, ultrasound (US), and MRI were performed. Articular disease by tuberculous and nontuberculous mycobacteria have similar presentations, clinically as well as radiologically, and have to be differentiated from other chronic bacterial or fungal infections, pigmented villonodular synovitis, rheumatoid arthritis, gout, hemophilia, and synovial chondromatosis. Although atypical mycobacterial involvement of the skeleton and soft tissues is relatively uncommon, its incidence is increasing, as is the incidence of extrapulmonary tuberculosis in western countries. The triad of Phemister is reemphasized, and the US and MRI findings are demonstrated. The definitive diagnosis has to be made by culturing biopsied synovium or synovial fluid.

A comparative study of synovitis in Saudi Arabia and Malaysia was made with a view to determining any geographic variation in the incidence and pattern of the arthritides. The diagnostic spectrum in both series included pyogenic arthritis, rheumatoid arthritis, brucellar and tubercular arthritis, gout, pigmented villonodular synovitis, synovial chondromatosis and acute rheumatic fever. Date-palm thorn synovitis was observed only in the Saudi Arabian series. While brucellar and tuberculous arthritis were predominantly seen in Saudi Arabia, the incidence of rheumatoid arthritis, pigmented villonodular synovitis and acute suppurative arthritis was almost equal in both countries.

The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemophilic patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use of MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or high-resolution coils, the investigation of the ankle joint still offers a wide spectrum of innovation for the next years, which is particularly enforced by the increasing demand for specific diagnosis of chronic diseases in orthopedic medicine.

Acral chondrosarcoma is rare. Synovial chondrosarcoma is even rarer. Synovial chondrosarcoma arising without evidence of pre-existing or concurrent synovial chondromatosis is exceedingly rare. We present a case of acral synovial chondrosarcoma involving both sides of the metacarpophalangeal joint of the thumb in a 69-year-old man. Radiographically, the lesion mimicked gout. On MR imaging, the lobulated contours of the soft tissue mass suggested synovial chondromatosis. Histological examination revealed a chondrosarcoma, which on the basis of imaging findings we present as having arisen from the synovium. The tumor invaded a portion of the cartilage of the metacarpophalangeal joint and equally destroyed the bones of the distal metacarpal and base of the proximal phalanx of the thumb, while sparing the bony joint surfaces.

The management of hip injuries in athletes has evolved significantly in the past few years with the advancement of arthroscopic techniques. The application of minimally invasive surgical techniques has facilitated relatively rapid returns to sporting activity in both recreational and elite athletes. Recent advancements in both hip arthroscopy and magnetic resonance imaging have elucidated several sources of intraarticular abnormalities that result in chronic and disabling hip symptoms. Many of these conditions were previously unrecognized and, thus, left untreated. Current indications for hip arthroscopy include the presence of symptomatic acetabular labral tears, hip capsule laxity and instability, chondral lesions, osteochondritis dissecans, ligamentum teres injuries, snapping hip syndrome, iliopsoas bursitis, and loose bodies (for example, synovial chondromatosis). Less common indications include management of osteonecrosis of the femoral head, bony impingment, synovial abnormalities, crystalline hip arthropathy (gout and pseudogout), infection, and posttraumatic intraarticular debris. In rare cases, hip arthroscopy can be used to temporize the symptoms of mild-to-moderate hip osteoarthritis with associated mechanical symptoms. This article discusses the current clinical and radiographic methods to detect early hip joint disease and the current indications and surgical techniques of hip arthroscopy.

Advancement in diagnostic and therapeutic applications for hip arthroscopy have dispelled previous myths about early hip disease. Arthroscopic findings have established the following facts: Acetabular labral tears do occur; acetabular chondral lesions do exist; tears are most frequently anterior and often associated with sudden twisting or pivoting motions; and labral tears often occur in association with articular cartilage lesions of the adjacent acetabulum or femoral head, and if present for years, contribute to the progression of delamination process of the chondral cartilage. Magnetic resonance arthrography represents an improvement over conventional magnetic resonance imaging, it does have limitations when compared with direct observation. Although indications for hip arthroscopy are constantly expanding, the most common indications include: labral tears, loose bodies, chondral flap lesions of the acetabular or femoral head, synovial chondromatosis, foreign body removal, and crystalline hip arthropathy (gout, pseudogout, and others). Contraindications include conditions that limit the potential for hip distraction such as joint ankylosis, dense heterotopic bone formation, considerable protrusio, or morbid obesity. Complication rates have been reported between 0.5 and 5%, most often related to distraction and include sciatic or femoral nerve palsy, avascular necrosis, and compartment syndrome. Transient peroneal or pudendal nerve effects and chondral scuffing have been associated with difficult or prolonged distraction. Meticulous consideration to patient positioning, distraction time and portal placement are essential. Judicious patient selection and diagnostic expertise are critical to successful outcomes. Candidates for hip arthroscopy should include only those patients with mechanical symptoms (catching, locking, or buckling) that have failed to respond to conservative therapy. The extent of articular cartilage involvement has the most direct relationship to surgical outcomes. Improvements in technique and instrumentation have made hip arthroscopy an efficacious way to diagnose and treat a variety of intra-articular problems.

This review presents an algorithm for the standardised histopathological diagnostics of synovial biopsies and synovectomy specimens. In general, changes of the synovium can be inflammatory or non-inflammatory. To the latter group belong certain benign tumors such as the diffuse variant of the tenosynovial giant cell tumor, lipoma or synovial chondromatosis, additionally the rare group of storage diseases should be kept in mind. Inflammatory diseases can be discriminated into crystal-induced arthropathies such as gout and pseudogout, into granulomatous diseases such as tuberculosis, sarcoidosis and foreign-body inoculation, and into the large group of non-granulomatous synovitis. This group is by far the most common, and it often causes difficulties in assigning the histopathological findings to a concrete diagnosis. Therefore, the synovitis-score should be applied as a diagnostic device in these cases, leading to the diagnosis of a low-grade synovitis (which is associated with degenerative arthropathies) or of a high-grade synovitis (associated with rheumatic diseases), the sensitivity and specificity being 60.5% and 95.5%, respectively.

This review will suggest an algorithm for standardised histopathological diagnosis of synovial biopsies and synovectomy specimens. In principal, changes of the synovial membrane can be inflammatory or non-inflammatory. To the latter group belong some benign tumors, such as tenosynovial giant cell tumor, lipoma or synovial chondromatosis. Rare non-inflammatory changes are the group of storage diseases. Inflammatory synovial diseases can be differentiated into crystal-induced arthropathy, such as gout and pseudogout, granulomatous diseases, such as tuberculosis, sarcoidosis and foreign body reactions and into the large group of non-granulomatous synovitis. This last group is by far the most common and often causes difficulties in assigning the histopathological findings to a definite diagnosis. Therefore, the synovitis score should be applied in these cases as a diagnostic means, leading to the diagnosis of low-grade synovitis (which is associated with degenerative and posttraumatic arthropathies) or high-grade synovitis (associated with rheumatic diseases), the sensitivity and specificity being 60.5% and 95.5%, respectively. In detritus synovitis the synovitis score is not applicable.
