[Clinical and radiologic long-term follow-up of Eden-Lang operation in habitual anterior shoulder dislocation].

The incidence of degenerative arthritis after Eden-Lange procedure is judged differently in literature, recently high rates of degenerative arthritis have been reported. 37 patients and the same number of shoulder joints have been evaluated clinically and radiologically after an average follow-up time of 14.9 years. Overall results can be considered as good. Recurrence of dislocation occurred only in one case. Most frequently we observed a limitation of external rotation and overhead performance in sports. The frequency of degenerative arthritis was 17%, clearly less than mentioned elsewhere. The Eden-Lange procedure still can be recommended as a treatment for recurrent anterior shoulder dislocation except for patients with high expectations in physical overhead activities.

[Chronic posterior shoulder dislocation].

The posterior dislocation of the shoulder is frequently unrecognized for many days, months or even years after the initial accident. After the presentation of its clinical and radiological features, as the different ways of its treatment, some cases will illustrate this entity, too frequently missed or wrongly treated.

[Habitual peroneal tendon dislocation].

Between 1945 and 1985 a total of 54 patients were treated for recurrent dislocation of the peroneal tendon. 30 cases were operated on employing five various surgical techniques. 31 patients denied trauma as being the cause, which therefore made constitutional weakness of the retention apparatus of the peroneal tendon responsible. The pathogenesis is described in detail. The period of follow-up is 13.2 years (2-40). 80% of the operated patients became absolutely trouble-free. Only in one single case did a relapse occur.

[Synovial chondromatosis].

Synovial chondromatosis is a rare, mostly benign, and monoarticular disorder of unknown cause, and it is characterized by multiple calcified bodies. It mostly affects the knees, the hips, the elbows, or the shoulders of adult men. The radiographic appearance is characteristic, but the presence of cartilaginous metaplasia on histological examination is conclusive. Excision of the chondral bodies and synovectomy is the treatment of choice and usually gives good results with a low risk of recurrence.

[Etiology and pathogenesis of synovitis villonodosa pigmentosa].

Articular pigmented villonodular synovitis is a benign synovial disease of unknown etiology. It is a proliferative disorder of the synovium that can involve the joints, tendon sheaths, and bursae. There is a predilection for involvement of the lower extremities, particularly the knees. There are two histologically similar lesions of pigmented villonodular synovitis: "nodular" and "diffuse" pigmented villonodular tenosynovitis. The typical clinical course consists of progressive and painful swelling of the involved joint. Cystic erosions without sclerosis and invasion of adjacent bone from intra-articular synovial lesions are the typical roentgenographic manifestations. The surgical treatment of the lesions is discussed. A review of the literature is given and our own material on 47 patients is presented to illustrate the different features of the disease.

[The femoropatellar pain syndrome. Conservative and surgical therapy in a long-term comparison (10-20 years) and their therapeutic consequences].

Long term results in conservative and operative treatment (10-20 years) and their therapeutical consequences. There are many factors involved in the aetiology and pathogenesis of the patellofemoral pain syndrome. Increased pressure over the lateral facet with or without reduced pressure over the medial of the patella resulting from lateral positioning of the patella and different anatomical variants not of the patella, but of the condyles must be considered as well functional variants in the muscular and ligamentous system. Overviewing the literature we compare the long term results of operative versus conservative treatment. 75 patients, treated by the method of Maquet-Roux, and 150 patients, treated conservatively, showed satisfactory results in 72%, a Lysholm Score of 90.8 in the "Maquet"-group, but 89.9 points in the "conservative"-group with a follow-up of 23 years. In the "conservative"-group 52% had no signs of arthrosis, in the "Maquet"-group there are only 30% without signs of arthrosis. The X-ray examination had mostly shown a further stage of arthrosis not only in the femoropatellar, but also in the femorotibial compartment, especially in the "Maquet"-group.

[4-year results following Insall anterior cruciate ligament-plasty].

From May 1984 until December 1987 56 anterior cruciate ligament reconstructions were done in cases with single plane anteromedial instability, using the bone block iliotibial band transfer. The anterior distal part of the iliotibial tract with its osseous insertion from Gerdy's tubercule was used. The immediate fixation of the bone block by a screw or by threads to the tibia allows early motion of the knee, because no immobilization is necessary. There were 56 patients: 14 women, 42 men; 34 right, 22 left. About the same number (65) with more severe multiplane laxity had been treated by other methods for reconstruction or augmentation of the anterior cruciate ligament. The average follow-up is 25.06 (6-52) months for these patients (12.88). All patients had full extension of the involved knee. None had an effusion and only eight complained of occasional pain. At follow-up some laxity was detected by the anterior drawer test and Lachman test (20 degrees). The LYSHOLM Score was very high at the time of follow-up = 98.67 points.

[Arthroscopy and MRT of the shoulder--a comparative retrospective analysis].

MR Imaging is proving to an effective means for evaluating the shoulder. The use of a surface coil and high resolution scanning techniques have allowed detailed analysis of normal anatomy and suspected pathology of the shoulder. On the other way arthroscopic inspection provides a more extensive visualization of the joint in different positions. 31 patients, well documented, were studied with MR Imaging and correlated with findings in arthroscopy and open revision in some cases. The MR studies were retrospective interpreted without the knowledge of the results of other diagnostic procedures. For the evaluation of rotator cuff tears MRI proved to have a sensitivity of 83.3% and an accuracy of 90.3%. When Arthroscopy was correlated with open revision the sensitivity was 61.8% and the accuracy 78%. Labral pathology and Hill-Sachs lesions will be better evaluated in arthroscopy as in MRI (sensitivity of arthroscopy 100% and of MRI 69%, accuracy of arthroscopy 100% and of MRI 87.1%). With the high resolution scanning technique and a surface coil MRI has been shown to be useful in the evaluation of rotator cuff tears and impingement syndrome but not in diagnosis of labral pathology and Hill-Sachs lesions.

[Synovitis villonodosa pigmentosa of the foot--diagnosis, therapy and long-term course].

The typical clinical cause of articular pigmented villonodular synovitis consists of progressive and painful swelling of the involved joints, bursae and tendons. The roentgenographic manifestations of this condition are usually nonspecific and consist of occasional superficial osseous erosion and cystic changes. Although these appearances may suggest the correct diagnosis, the precise diagnosis depends on examination of the tissue. Pigmented villonodular synovitis is a non-malignant disease entity of controversial origin and nature. The intraarticular form is characteristically monoarticular and affects predominantly the knee, the hip and the foot. We present 15 cases of pigmented villonodular synovitis of the foot, treated in a period from 1960 to 1986. In 11 patients the clinical and radiographic results were reviewed at an average of 15 years (rage: 3-26). The treatment of 5 recurrences and the differential diagnosis are discussed.

[Difficulties and complications in arthroscopic meniscus surgery].

Arthroscopic meniscectomy is one of the most sophisticated techniques in arthroscopic surgery. The actual meniscus resection is a simple surgical exercise - most problems and difficulties arise from the arthroscopic technique. With the aid of legholder, water pumps, video cameras, miniature instruments, motor-driven shavers and Laser-systems (Excimer) it would be possible, to reduce technical problems. Broken instruments are mostly the fault of the surgeon, because force is applied to the delicate tools in tight cavities. It is not just the instrument, which suffers in such cases, but the cartilage of the joint. Several examples of meniscus tears are described to show the possibilities, difficulties and complications of arthroscopic meniscus surgery.

[Diabetic osteoarthropathy. Course and differential diagnosis].

Diabetic neuropathy with reduced sensitivity to pain and mechanical overloading of the joints, associated with frequently disturbed circulation in the lower extremities, are the etiopathogenetic factors of diabetic osteoarthropathy (synonyms: neuroarthropathia diabetica, Charcot joint). In the first stage there is osteonecrotic destruction of bone and cartilage. Clinically, an insidious, painless, noninflammatory hydroarthrosis with massive swelling of the soft tissues is typical. Subsequently, in stage II, irregular transformation of the bone due to multiple resorptive processes occurs. In the third stage this transformation process stabilizes and the bone ends become more pointed and more sclerotic (resembling a licked candy stick). For mechanical reasons, the tarsometatarsal and metatarsophalangeal joints and the metatarsals are primarily affected. However, destruction is also seen in Chopart's joint, the talus, the calcaneus, the ankle joint and the distal tibia. With regard to differential diagnosis, similar clinical pictures are seen in many neuropathic bony changes--tabes dorsalis, syringomyelia, myelodysplasias, congenital analgesia, congenital familial acroosteolysis. More difficult to differentiate are osteomyelitic foci, bone tuberculosis, and malignant bone tumors involving bone destruction.
