[After care of surgically treated ruptures of the outer ligaments of the anterior ankle joint with special reference to the special Dr. Spring shoe].

P.o. treatment of ankle joint ligament ruptures via the special shoe "adimed-STABIL" can avoid the disadvantages of complete immobilisation with a cast. An essential condition for this type of management is the reliable prevention of extreme movements by means of this shoe, such as supination, adduction as well as maximal extension and flexion. In 10 patients with ankle joint ligament ruptures we could demonstrate that the special shoe could not fulfil these requirements, as demonstrated by stress x-rays with the correctly laced shoe under anaesthesia. Due to these results immobilisation of the ankle joint by cast after reconstruction of the ligaments appears to be the method of choice. Our observations in cases of ankle joint lesions could not confirm the fear that prolonged cast immobilisation would lead to trophic changes and would require functional physiotherapy. Because of the disadvantages of the special shoe in respect of insufficient stability, high cost, lack of ventilation and the problems involved in applying or taking off the shoe, or in remaining in "shoeless condition", we can recommend using this shoe in aftercare treatment in exceptional cases only.

[Late results after meniscectomy].

Lesion of the meniscus is the most frequently occurring lesion in the region of the knee joint. Opinions are still divided as to the effects of partial, subtotal or total meniscectomy in provoking and/or promoting arthrosis. In this study, 70 patients with isolated injury of the meniscus were followed up on an average 11 years after meniscectomy. The subjective and clinical findings are juxtaposed with the x-ray findings. It was found that no arthrosis or no increase of the already preoperatively existing degree of arthrosis was seen in only 21.4% of the patients. Correlations are set up between instability resulting from meniscectomy on the one hand, and degree of arthrosis on the other.

[Treatment tactics in fractures of the midfoot].

Metatarsal fractures can occur as isolated lesions in combination with injuries of the ipsilateral tarsus, or in chain injuries of the lower extremity, or within a polytrauma. The choice of surgical or conservative therapy depends significantly on localisation and dislocation of the fracture (especially the involvement of the metatarsus I or V), as well as on the extent of the primary or expected soft part damage. From 1974 to 1984, 137 patients with metatarsal fractures were treated as in patients at the Accident Hospital in Tübingen. Three groups of diseases indicated for surgery are evident from an analysis of the courses of the disease: Metatarsal fractures in combination with an ipsilateral tarsus fracture or tarsus dislocation. Metatarsal serial fracture especially in involvement of metatarsus I and/or V. Dislocated tear fracture of the base of the fifth metatarsal bone. Preference is given to percutaneous Kirschner wiring from the head of the injured metatarsal bone. The tear fracture of the base of the metatarsal bone V is treated via traction bandage. These methods are generally technically simple and enable early functional treatment and partial weight-bearing. In particular, immediate surgical treatment may not only favour reposition and retention, but may also limit damage of the soft parts.

[Diagnosis and therapy of traumatic posterior shoulder dislocations].

In cases of dislocation of the shoulder the humeral head almost always dislocates anteriorly. Only rarely does the dislocation result in a posterior position of all or part of the humeral head. The diagnosis of posterior dislocation is not always as easy as the diagnosis of anterior dislocation and for this reason the injury is often missed. Cisternino et al. found that over 50% of patients with posterior dislocation of the shoulder were missed on initial examination. The longer the time between accident and treatment, the more difficult that treatment becomes and the harder it is to achieve a satisfactory functional result. Therefore it is vital to think of this injury in all cases of severe contusion of the shoulder and if there is the slightest suspicion of this injury, the patient must be aggressively investigated to establish the relationship between the humeral head and the glenoid.

[Prognosis of injury of the distal tibia epiphysis depending upon the type of injury].

A follow-up of 51 patients after lysis or fracture of the distal tibia epiphysis showed that growth disturbance independant of the type of injury can occur (6 patients after Aitken-I and 1 patient following Aitken-III injury). The dislocation seems to be a good sign concerning the disturbance of blood supply. All 7 patients with growth disturbance showed a severe dislocation.

[Significance of the fibula in tibial fractures and pseudarthroses].

The importance of the shaft of the fibula in lower leg fractures is the greater, the more unfavourable the situation of the tibia together with the surrounding soft tissue. We consider the operative stabilisation of the fibula to be a good procedure in cases of distal lower leg fractures, comminuted fractures of the tibial shaft and intramedullary nailing of the tibia, to increase overall stability of the whole lower leg system. The fibula is of still greater importance in cases of non-unions with loss of bone, with or without infection. The reconstruction of the tibial bone defect can be achieved via the stable fibula by means of several modifications of the fibula-pro-tibia operation. It can be demonstrated by various examples that the fibula and its stability should be considered more often in the therapeutic management of lower leg fractures and non-unions of the tibia.

[Fractures in benign bone cysts].

Etiology, clinical manifestations, roentgenographic appearance and histological variations of solitary and aneurysmatic bone cyst are reported. The classification of solitary bone cyst into active and inactive cysts is important therefore prognosis and treatment are different. The critical control of our patients with fractured solitary and aneurysmatic bone cysts since 1973 resulted in a very contenting management of treatment. Active solitary bone cysts, recurrent cysts, fractured cysts and large cysts close to joints are treated by segmental resection, interposing of ribs, homologous or autogenous cancellous bone graft and plate osteosynthesis. We never found recidives under this treatment. The only curettage of active solitary bone cyst frequently is accompanied by recidive and unsatisfying functional results. Reports of local corticoid injections in treatment of bone cysts should be furthermore controlled critical.

[Intramedullary nailing, an unstable but load bearing osteosynthesis].

In primary closed and simple fractures the local bone healing type--primary or secondary bone healing--after internal fixation depends on the stability/rigidity which has been achieved and secured. This fact is not only of scientific interest but is also important and essential for a correct assessment of the postoperative clinical course. This is demonstrated and discussed by means of intramedullary nailing, which is an unstable osteosynthesis but which allows early loading.

[Therapy of chronic antero-lateral instability of the upper ankle and its results].

From 1970 to 1980, 157 modified Watson-Jones grafts were performed at the BG Unfallklinik Tübingen. The advantages and disadvantages of this procedure are discussed and compared with other surgical procedures. Follow-up examinations were possible in 119 patients. In all patients a significant improvement of the stability could be attained. The functional reduction of mobility appeared minimal. 46 of 64 athletes resumed full sports activities. 90% of the patients stated to be satisfied with the results.

[Treatment of knee joint empyema].

This report deals with 42 patients suffering from purulent infections following aseptic operations, perforating soft tissue injuries or implantation of endoprostheses. By early revision of the joint in combination with gradually increasing physiotherapy (under medical supervision!) in all cases except endoprostheses the infection could be brought under control and a satisfactory functional result achieved. In all cases of infected endoprostheses the prosthesis could not be preserved, the infection of the knee-joint could only be cured by removing the foreign body and arthrodesis.
