[Cryotherapy. Behavior of joint temperature during ice application-- a basis for practical use].

Changes of intraarticular temperature were measured in ten young animals during long-term cryotherapy. The use of cold packs of -23 degrees C and an application time of 30 minutes resulted in a decrease of intraarticular temperature of means = 6.56 +/- 1.04 degrees C. The original temperature was reached again after an average of 215 minutes. With cryotherapy there is an initial reflex increase in temperature is the primary object of therapy, all movements commencement of application. Since movements of a joint result in the mixing of synovia of various temperatures, we recommend the following procedures in cryotherapy: 1. during the application of cold (cooling phase) the patient is ask to move his joint from time to time, in order to attain a faster and more effective decrease in temperature in the joint. 2. But in this cases, in which an intraarticular decrease in temperature is the primary object of therapy, all movements should be avoided during the phase of rewarming. The effect of long-term cryotherapy (Kern, 1980) is a decrease in temperature of sufficient magnitude and duration resulting in a reduction of joint metabolism, thereby of the activity of cartilage degrading enzymes. Accordingly, long-term cryotherapy can be recommended using cold packs of -20 to -23 degrees C for 30 minutes every 5 to 6 hours in acute rheumatic arthritis, posttraumatic oedema and in the acute therapy of sports injuries. A thin towel or blotting tissue is used to avoid local freezing. Slight exercise during the cooling phase can improve the results of cryotherapy.

[Electrotherapy of pain relief using the Tenzcare stimulator. A clinico-experimental study].

Electrotherapy was introduced into the aftercare programme for patients with serial rib fractures in the acute stage, shoulder injuries or fractures of the radius. Electrical stimulation was carried out with the Tenzcare Nr. 6240 apparatus. The results were significantly better in each of the three groups than in the respective control group. Patients after thorax trauma complained less of pain in the acute phase: there was less pulmonary secretion on X-ray and, on average, their blood gas values returned to normal three days earlier. None of them required assisted respiration. Patients with shoulder injuries or fractures of the radius complained less frequently of pain during physio-therapy after removal of their plaster casts. They attained their optimum range of movement on average ten and eight days earlier, respectively than the controls.

[Arterial spasm caused by administration of DHE-heparin in a tibial fracture].

A 38 years old white woman suffered a tibial fracture which was primarily managed by traction therapy. 3 X 5000 IU Heparin DHE was given as prophylaxis against thromboembolism. 6 days after administration of the drug a severe arterial spasm (documented by arteriography) with high-grade ischaemia of the left leg occurred. Successful arterial dilatation with a Fogarty catheter within the entire infragenual region down to the foot arteries was performed and consecutively during the same anaesthesia the intramedullary stabilisation using an interlocking nail was also performed. 8 months later the patient was free from symptoms, the fracture had healed, and the function was unrestricted. All pulses were palpable and the ultrasound Doppler index was greater than 1. In conclusion, we recommend in arterial spasm during heparin DHE therapy, immediate operative exposure of the vessel--if possible under local anaesthesia--and adequate vascular surgery as balloon catheter dilatation.

[Treatment of infected tibial fractures and pseudarthrosis using an external fixator].

The clinical course and the results of our treatment of 18 patients with External Fixator after infection or pseudarthrosis are demonstrated. On an average of 6.1 months the patients wore the external fixator, the time of consolidation of the fracture was 17.2 months from the accident. At the date of examination - 16 months to 10 years after removal the external fixator all fractures and pseudarthroses were united. Two patients still had a fistula three years after removal of the external fixator. Three patients had slight pain in the area of the former fracture or the complication-wound; disturbance of sensibility in the area of the scar and the meshgrafts were found at 11 patients. The mobility of the knee joint was nearly free in all patients, the mobility of the ankle joint was impaired in most of them.

[Use of an external minifixator in severe open injuries of the hand].

Since January 1979 we have treated 14 patients at the 1st University Clinic of Traumatology in Vienna with the MFE described by Jaquet. The MFE was used mainly in severe open fractures of fingers and metacarpal bones. All 14 patients were examined for follow-up after a mean interval of 20 months. This method of treatment warrants minimal strain on the soft tissues while it ensures stability and optimal care of the wounds. Osseous consolidation was achieved in 13 of 14 patients; although one patient developed pseudarthrosis, he was, like 12 other patients, perfectly satisfied with the result of surgery. Only one patient was less satisfied by the result, as there was a rotational and axial deviation of 30 degrees between the fragments. However she refused operative correction, as the deviation does not interfere with her profession.

[Rare indications for an external fixator].

Seldom indications for the use of external fixator are reported and illustrated. As a rule the damage to the pelvis is complex and it is often associated with a polytrauma; unstable pelvis injuries in some cases can be stabilised by external fixator by the method of Slätis. Examples of osteotaxis are given for the treatment of comminuted fractures or defect-pseudarthroses or after osteomyelitic bone damage of femur and humerus. In the treatment of multi-fragment fractures of the base of the radius and of the forearm the external fixation can also be used with good success. The external mini-fixator is a new way for external stabilization in hand surgery and can provide good results in comminuted fractures of the fingers and for finger-replantation.

[Significance of the limbus glenoidalis for the stability of the shoulder joint].

Besides the osseous structures and the muscular elements, the capsular and ligamentous apparatus, including the limbus genoidalis, is of utmost importance for the stability of the shoulder-joint. In the literature the limbus glenoidalis (L.G.) is generally described as a fibrocartilagineous structure comparable to the menisci of the knee-joint. Basically, the cause of a primary foreful shoulder-dislocation may be either a direct or an indirect trauma. The lesions during luxation concern the joint's capsula, the L.G. and the head of the humerus. However, in the literature one finds many different explanations as to which of those lesions is responsible for the subsequent development of recurring shoulder dislocation. The variability of concepts is reflected by the large number of operative procedures that are advised as treatment of a recurring dislocation. Assuming that the L.G. substantially contributes to the stability of the shoulder joint, we have investigated structure, blood-perfusion and anatomical connections of the L.G. The mechanism of the primary shoulder dislocation was simulated in mechanical strain-experiments, carried out on human corpse specimens. The occurring lesions were analysed. The following investigations were undertaken in alltogether 182 fresh specimens of human shoulder joints: measurement and calculation of the joint-surfaces of scapula and humeral head, dye-injection of the arteria axillaris, in order to demonstrate the vascular supply of the limbus glenoidalis, histological examination of the structure of the limbus glenoidalis, mechanical strain-experiments, that simulate the dislocation mechanism of the shoulder-joint. The calculations of joint-surfaces showed a relative decrease of the scapular joint-surface with growing age. The relation of the scapular joint-surface (always plus limbus glenoidalis) to the joint-surface of the humeral head is 1: 2.25 +/- 0.38 in men and 1: 2.20 +/- 0.11 in women (age-group: 20 to 49 years). In the age-group of 70 to 89 years the respective numbers are 1: 2.90 +/- 0.35 and 1: 2.99 +/- 1.04. The differences in the relations of surfaces between the different age-groups are statistically significant for both sexes (p less than 0.01; Student-t-test). The dye-injection showed that the main artery supplying the limbus glenoidalis is a branch of the arteria circumflexa scapulae. This branch is connected by several anastomoses with the arteriae circumflexa humeri anterior and posterior. These macroscopical observations were confirmed by histological and microangiographic examinations.(ABSTRACT TRUNCATED AT 400 WORDS)

[Local treatment of post-traumatic infections with debrisorb].

Debrisan is an highly hydrophilic dextran polymer in the form of dry, spheric beads. When dry Debrisan beads are placed on a wound, the wound secretions are sucked up into and between the beads. No crust is formed on the wound. Bacteria and granular substances are removed with the secretions. In a prospective study 20 patients were treated with Debrisan. 8 patients had local wound infections and there was a healing-up inert 6.1 days in every case. 12 patients with osteomyelitis had a poor result in 3 cases, because they had still fistulization after 10 days procedure. The treatment of osteomyelitis must be surgical in the first place. Debrisan may only have the character of an adjuvans.

[The effect of standardized acupuncture programs in the after-care of accident patients].

153 patients suffering from pain, edematous conditions, and impaired movement following traumas sustained in accidents were treated or after-treated with acupuncture. Acupuncture was applied in adherence to a standardized program according to the individual types of injury. The stimulus was applied by means of steel needles inserted into body as well as ear acupuncture points. In all 9 groups, improvement of the painful condition was significant to highly significant as it was regarding improvement of the movement impairment, the latter not having been emphasized in the other 3 groups. Remaining complaints of long standing following accident traumas could also be positively influenced. Acupuncture proved itself to be an effective form of therapy for after-treatment of accident patients, presenting a valuable supplement to the field of rehabilitation, especially when combined with other physical therapeutic measures.

[Testing the effect of acupuncture in accident patients using skin temperature measurements].

Skin temperature was studied on a group of 54 patients suffering from accident traumas and 20 healthy probands during and after treatment. In all patients there was a very significant rise in skin temperature in the area of the lesion which persisted beyond the treatment period, and in some cases even increased. This effect was also observed to a lesser extent on the contralateral, untreated extremity. No change in skin temperature was observed in the healthy probands who were treated in the same manner. This leads to the conclusion that needle stimuli in the area of lesions have not only a local, hyperemic effect, but also demonstrate superregional actions; this is, however, dependent on the integrity of the organism.

[Exact method for the measurement of the rotation of the humerus head in the shoulder joint using computed tomography].

An exact method of measuring the degree of inward-and outward rotation in the humero-scapular joint is demonstrated. The advantage of the use of computed tomography as compared with the clinical method of measurement is the accurate differentiation of the mobility of the individual parts of the arm's mobile elements with respect to the trunk and the documentation of the result. For inward rotation we have measured a mean value of 38 degrees on the right side and of 37 degrees on the left; the corresponding values for outward rotation were 37 and 41 degrees. In eleven patients who had undergone Bankart's operation we found the outward rotation of the arm in the shoulder joint decreased to a mean value of 15 degrees.

[Experiences with the femur head prosthesis in femoral neck fractures].

The clinical and radiological course of 117 patients with a femur head prosthesis and a medial fracture of the neck of the femur is reported. In 1981 the range of indications was extended, including now all types of fracture in the elderly except those fractures that are impacted or not dislocated. By the date of follow-up in summer 1982 68 patients had died. In 29 of these mobilization had failed at all because of their bad general state of health, whereas 39 patients were able to walk from one month up to four years before they eventually died. Follow-up of the 49 patients that are alive showed that 24 can walk without any support, whereas 21 have to use a walking-stick or crutches. The remaining four patients are unable to walk because of old age debility.

[Late results after conservative treatment of juvenile leg fractures].

In 50 patients, who had had tibiofibular or isolated tibial fractures in childhood, we have done a clinical and radiological assessment after completion of growth. The length of both calves was compared exactly with orthoradiographic measurements. The length of the lower limbs was identical in 20 subjects and it differed by maximally two centimeters in 30 subjects, in twelve of which there was a residual deviation of the axis of five to nine degrees. From the comparison of the radiographs at the end of treatment and during the control examination it became clear that due to the continuing growth the axial deviations would decrease by maximally seven degrees in children under twelve whereas they would remain virtually constant after the age of twelve. Therefore axial deviations up to five degrees are acceptable in children under twelve years but they must be avoided after the age of twelve. Torsional dislocations must be corrected anyway. In children under twelve years lengthening occurs due to hyperemia of the epiphyseal junction. However, beyond twelve shortening of the fractured calf occurs. Therefore an initial shortening of maximally one centimeter is acceptable in children under twelve. But in older children the initial consolidation with an equal length of legs must be attempted in order to prevent a permanent difference in length after the completion of growth.

[Initial results with the dynamic hip screw in comparison to other osteosynthesis procedures].

30 fractures of the proximal end of the femur were stabilised with so-called "dynamic hip screws" (AO/ASIF). This method seems to be more suitable for some inter-trochanteric fractures which pose problems questioning our usual treatment with Ender's elastic round nails. The dynamic hip screw system is also more stable for femoral neck fractures of type Pauwels III than 4 cancellous bone screws. One phenomenon which can not yet be fully explained is the slipping out of the screw to an extent unobserved in other procedures.
