The principal clinical features and radiological findings relating to the locomotor system have been studied in 32 consecutive hospital admissions of patients with Wilson's disease. 5 of these patients were recently diagnosed and had as yet received no treatment, while 27 were routine admissions for follow-up and biochemical supervision of their illness. No patient was specifically included or excluded from the series because of the presence or absence of locomotor symptoms. The most common radiological abnormality was a generalized increase of radiolucency, interpreted as skeletal demineralization (21 cases), followed by premature osteoarthrosis (8 cases). Changes in the spine were common and included osteochondritis, reduction of intervertebral joint spaces, osteoarthrosis, and a tendency to squaring of vertebral bodies. Other bony changes included fluffy irregularity of femoral trochanters, osteochondritis dissecans of the knees, osteophytic protrusions at bone ends, and bunches of tongue-like osteophytes at joint margins. The symptoms associated with these radiological abnormalities comprised back pain and stiffness with restricted movement, pain and stiffness of knees, hips, and wrists, and tenderness to pressure over margins of affected joints. Joint hypermobility was also observed in 9 patients. Episodes of acute polyarthritis with serological changes were seen in 5 cases; all these episodes appeared to be related directly to treatment with penicillamine.

Ten cases of osteochondritis dissecans of the humeral capitellum which were treated surgically are reviewed. All 10 cases were males and involved the dominant side. The ages at surgery ranged from 13 to 17 years. Follow-up ranged from 1 to 7 years. All of the youths had competed in organized athletics, either baseball or football. By position there were three pitchers, two catchers, two infielders, and one outfielder; in addition there were one quarterback and one linebacker. Only one patient presented with locking of the elbow, whereas the others presented with pain and limitation of extension. The locked elbow was explored immediately and the others were explored after immobilization failed to relieve their symptoms. In seven of the joints a loose fragment of the capitellum was found lying either in the joint or in a defect in the capitellum. The fragment had multiple small holes. In three cases there was no loose fragment. In this situation a corticol window was cut above the capitellum. The capitellum was then drilled and bone was grafted from above. Over all, there were one excellent, six good, one fair, and two poor results. There seemed to be little difference between curretting alone or curetting and drilling. The cases with the cartilage intact and bone grafted from above did worse, with one fair and one poor result of three cases. The two poor results required further surgery, which consisted of partial excision of the capitellum. All cases lacked elbow extension before and after surgery, but nine of 10 gained some motion after surgery. Pre- and postoperative x-rays are shown in this report and a brief review of the literature concerning osteochondritis dissecans is presented.

The clinical findings, roentgenographic findings, and results of various forms of treatment of osteochondritis dissecans in 50 elbows were reviewed in a study of the records of 42 patients. All the patients were males; two-thirds were between 9 and 15 years of age when they first had symptoms. Pain, loss of motion, locking, and clicking were the most common symptoms. Roentgenographically, rarefaction and flattening of the capitellum were common features. Some form of surgical treatment was used for 38 elebows; removal of loose bone and curettage and trimming of the crater were the most frequent procedures. The results of treatment were generally satisfactory. This review suggests that loose bodies should be removed and that, in most instances, no other procedures are indicated.

Thirty-one patients with osteochondritis dissecans of the capitellum humeri were followed for an average of 23 years. There were symptoms in about half of the elbows at the follow-up examination. Impaired motion and pain on effort were the most common complaints. Roentgenographic signs of degenerative joint disease were present in more than half of the elbows and correlated with a reduced range of motion. The diameter of the radial head increased in comparison with the contralateral elbow in two thirds of the patients.

Arthroscopy of the ankle joint was limited to the anterior compartments for a long time. The key to the entire diagnostic and therapeutic arthroscopy procedure on the ankle joint was the distension of the joint space through modern distraction techniques. The distraction devices available make arthroscopic surgery of the ankle joint as effective as in other joints like the knee and shoulder. Distension of the joint space allows visualization of all compartments, including the posterior ankle. In the case of hidden cartilage pathology of the posterior talus, an osteotomy linked with hardware removal through a second operation can be avoided today. The indications for arthroscopy of the ankle are pain, swelling, instability, hemarthrosis and joint locking. Generally, arthroscopy of the ankle joint is performed utilizing three general portals: anterolateral, anteromedial and posterolateral. Arthroscopic standard equipment, including the small joint set, is sufficient to treat the major part of ankle pathology through the standard portals. Arthroscopic ankle joint debridement in degenerative arthritis, removal of osteophytes, elimination of loose bodies and the management of soft tissue and bony impingement are possible. A complete synovectomy can be performed, including the posterior compartments. The treatment of osteochondritis dissecans is facilitated through the transmalleolar approach in combination with the distraction device. Arthroscopic ankle arthrodesis is possible and induces less trauma because an arthrotomy can be avoided. In our opinion diagnostic arthroscopy and arthroscopic surgery of the ankle joint is a procedure of great benefit for the patients if the indications are strictly adherred to.

One hundred patients with recently acquired, externally visible mandibular deformity and no history of previous extraarticular mandible fracture were selected for retrospective analysis. All had been investigated clinically and with radiography, tomography, and high-field surface-coil MR imaging to determine the presence or absence and extent of temporomandibular joint degeneration. Temporomandibular joint degeneration was found in either one or both joints of each patient studied. Chin deviation was always toward the smaller mandibular condyle or more diseased joint, and many patients either complained of or exhibited malocclusion, often manifested by unstable or fluctuating occlusion disturbances. Three radiologically distinct forms of degenerative vs adaptive osteocartilaginous processes--(1) osteoarthritis, (2) avascular necrosis, and (3) regressive remodeling--involving the mandibular condyle and temporal bone were identified in joints most often exhibiting meniscus derangement. Osteoarthritis and avascular necrosis of the mandibular condyle and temporal bone were generally associated with pain, mechanical joint symptoms, and occlusion disturbances. Regressive remodeling was less frequently associated with occlusion disturbances, despite remodeling of the facial skeleton, and appears to result from regional osteoporosis. Forty patients (52 joints) underwent open arthroplasty procedures, including either meniscectomy or microsurgical meniscus repair, at which time major radiologic diagnoses were confirmed. Surgical and pathologic findings included meniscus displacement, disk degeneration, synovitis, joint effusion, articular cartilage erosion, cartilage healing/fibrosis, cartilage hypertrophy, osseous sclerosis, osteophyte formation, osteochondritis dissecans, localized or extensive avascular necrosis, and decreased mandibular condyle mass and vertical dimension. We conclude that temporomandibular joint degeneration is the principal cause of both acquired facial skeleton remodeling and unstable occlusion in patients with intact dentition and without previous mandible fracture.

Synovial chondromatosis is a rare monarticular condition in which cartilaginous masses are formed by metaplasia of the synovial membrane. These masses may calcify and ossify. The disease most commonly affects the knee, and the symptoms include pain, swelling, locking and palpable loose bodies. Although the clinical features are usually non-specific, the roentgenograms often provide important diagnostic information. Synovial chondromatosis is rarely a difficult diagnostic problem, but should not be confused with other disorders that give rise to loose bodies, such as degenerative joint disease and osteochondritis dissecans. Two cases are described and synovial chondromatosis is discussed in some detail, including radiological features and treatment.

This article defines the characteristic features of osteochondritis dissecans of the trochlea of the femur, and indicates that important differences distinguish it from the more familiar femoral condylar form. The clinical features in 16 knees included: gradual onset of symptoms, pain with running and jumping, no significant history of injury; inconstant tenderness of the trochlea, and pain with resisted extension at 20 to 45 degrees. Diagnosis was usually difficult, and was often delayed because of subtle radiographic changes. Treatment depended on the stage of presentation. Nonsurgical treatment failed in four of seven knees. Drilling the lesions failed in two of the three cases. Fixation with small screws produced two good results; two others healed, but with short follow-up. Removal of the loose bodies from six knees produced one poor result and five good results. This process differs in presentation from femoral condylar osteochondritis dissecans. Although the results (average follow-up more than 5 years) were generally good, the mild symptoms probably represent incongruity of the patellofemoral joint, and probably foretell osteoarthritis.
