[The Lown-Ganong-Lewin syndrome--a rhythmologic unit?].

13 patients with the clinical diagnosis of a LGL-syndrome underwent a comprehensive analysis on account of therapeutically problematical tachycardias. In all cases the electrophysiological findings at most spoke for a partial av-node-shunt or for a small av-node, never for a complete bypass. The analysis of the tachycardia possible in 12 cases showed various mechanisms which by a stimulus circulating over a partial av-node-shunt could be explained in the sense of tachycardia only in 3 patients. It is concluded that different mechanisms underlie the clinically homogeneous picture of the LGL-syndrome concerning the development of a tachycardia.

[Plastic repair of the lateral ligament of the upper ankle joint: methods and results (author's transl)].

A review is given about common techniques for plastic repair of the lateral ligament of the upper ankle joint. Own experiences are presented. Indications for plastic repair age: old injury of the ligaments with clinical symptoms; fresh lesions of the ligament; if the tissues of the articular capsule or of the ligament are completely destroyed or if during surgery a chronic insufficiency of the ligaments becomes evident. Contraindications against plastic repair are: a marked arthrosis of the ankle joint, a permanent valgar displacement of the talus, old age and a high risk for surgery. The results of 13 plastic operations of the lateral ligament could be classified as "very good" in ten cases and as "good" in three cases (evaluation according to Marti). In seven cases a modified technique of Watson-Jones has been used, twice Weber's method and in four cases a direct ligament plastic. Those procedures are favoured which come close to the original anatomy, are easy to perform without destroying functional structures and which do not cause an unnecessary restriction of movement.

[Indication for surgical treatment of recent fibular ligament lesions. Comparative study after surgical and conservative therapy].

Results of clinical and or radiological follow-up examination of 134 patients with recent rupture of the lateral ankle ligaments are analysed. 69 cases have been treated conservatively, 65 cases by surgery. With regard to the findings at the first examination after the trauma conclusions are drawn concerning the indication for surgery. Operative findings and results of the treatment show conclusively that surgery is indicated when the opening of the injured ankle joint at strain is 10 degrees or more when compared with the intact side.

[Subtalar arthrodeses and arthrodeses of the ankle joint (author's transl)].

We present a check-up study of five arthrodeses of the ankle joint and five subtalar arthrodeses. The arthrodeses of the ankle joint were indicated because of hard pains after bimalleolar fractures and fractures of the pilon tibial. Subtalar arthrodeses were indicated in posttraumatic arthritis of the calcaneus after intraarticular fractures of the calcaneus. Resection-compression-arthrodesis following Charnley was used for the ankle joint, subtalar arthrodesis was done by the technic of using a corticocancellous bone graft from the iliac crest. With an average postoperative follow-up period of four years four from five patients in every group had a good results. In cases clear indication the early arthrodesis should be preferred.

[Results of 193 conservatively treated acute fractures of the carpal navicular--indications for operative treatment (author's transl)].

The results of 193 conservatively treated acute fractures of the carpal navicular are presented. Ninety-eight (50.7%) had horizontal oblique fractures, 82 (42.5%) transverse, and 13 (6.8%) vertical oblique fractures. In 23 (11.9%) cases the fracture was located in the proximal third, in 125 (64.7%) in the middle third, and in 45 (23.4%) in the distal third. An unpadded cast extending from the elbow to the metacarpophalangeal joints including the thumb was used generally. On the following day the cast was always completed by addition of a volar plaster splint and a circular plaster bandage. Duration of immobilization lasted from 6 to 16 weeks (mean: 10 weeks). On average, 4.5 years after injury 190 (98.4%) fractures had healed by osseous union and 3 (1.6%) had a pseudarthrosis. The reasons for non-union were too short time of immobilization, and former diastasis between the fragments. The number of arthrosis in the radiocarpal joint in our patients amounted to less than 1%. Primary operative treatment (open reduction and screwing) is preferred for vertical oblique fractures and for fractures with a large diastasis between the fragments. Secondary operative treatment is performed if there are no signs of osseous consolidation.
