Magnetic resonance imaging of injuries to the ankle joint: can it predict clinical outcome?

OBJECTIVE: To predict clinical outcome after ankle sprains on the basis of magnetic resonance (MR) findings. DESIGN AND PATIENTS: Twenty-nine consecutive patients (mean age 32.9 years, range 13-60 years) were examined clinically and with MR imaging both after trauma and following standardized conservative therapy. Various MR abnormalities were related to a clinical outcome score. RESULTS: There was a tendency for a better clinical outcome in partial, rather than complete, tears of the anterior talofibular ligament and when there was no fluid within the peroneal tendon sheath at the initial MR examination (P = 0.092 for either abnormality). A number of other MR features did not significantly influence clinical outcome, including the presence of a calcaneofibular ligament lesion and a bone bruise of the talar dome. CONCLUSION: Clinical outcome after ankle sprain cannot consistently be predicted by MR imaging, although MR imaging may be more accurate when the anterior talofibular ligament is only partially torn and there are no signs of injury to the peroneal tendon sheath.

Clinical examination and magnetic resonance imaging in the assessment of ankle sprains treated with an orthosis.

This is a prospective clinical study of treatment of ankle sprains with an ankle brace that permits ankle dorsiflexion and plantarflexion of 20 degrees, but limits inversion and eversion for 6 weeks. The ankle brace is followed by physiotherapy for another 6 weeks. Thirty patients were evaluated with clinical examination and magnetic resonance (MR) imaging before treatment and after 12 weeks of treatment. MR imaging revealed acute tears in the anterior talofibular ligament in all 30 ankles (100%) and tears in the calcaneofibular ligament in 25 of 30 ankles (83%). At 12 weeks after injury, MR evidence of healing was present for the anterior talofibular ligament in 22 of 30 ankles (73%) and for the calcaneofibular ligament in 23 of 25 ankles (92%). Postural sway analysis after therapy was used to quantify functional stability of the ankle. There was no correlation with MR findings, but there was a correlation with the subjective impression of functional instability. Twenty-eight of 30 patients (93%) had a functionally stable ankle after 12 weeks of treatment. MR findings after ankle sprain could not predict clinical outcome.

[Orthoses in patients with poliomyelitis].

Poliomyelitis, in spite of vaccination, is still a problem: in the third world as well as for the victims of the epidemics of the first half of this century, who now, becoming older, have growing difficulties to overcome their paralyses. They needed and still need orthoses for walking. How do they manage? And what can orthopedic technique offer them today?

[Optimal design of seating shells for communication disordered multi-handicapped patients with Nicol's capacitative pressure distribution].

Pressure distribution measurements have come into use in the 1930s. The technique started as a qualitative procedure, was developed to a semi-quantitative state and has recently attained a strongly quantitative status. An outline is given of the development of the technique, and the capacitive measuring procedure and its area of application are described. The article is focussed on the adaptation of seats for persons with multiple disability.

[Treatment of epicondylitis radialis and ulnaris humeri in tennis players with fraction bandage. Results of a field study].

Elbow bandages were tested at the Orthopaedic University Clinics Münster (Germany) and Zurich (Switzerland), as well as at the surgery of an established orthopaedic surgeon. Both the effect of the bandage, i.e. the soothing and de-swelling effect, the function improvement, therapy progress and success were monitored and evaluated. The rest was designed as a short-term study with standardised scoring. After the falsification principle, the therapeutic effect was confirmed if a positive effect was shown during this time interval. Twenty-six patients between the age 26 and 65 were tested, 16 males and 10 females. In 18 cases the right arm was treated and in 8 cases the left arm. 17 cases of epicondylitis radialis humeri and 5 cases of epicondylitis ulnaris humeri were found. The time of observation was 2 weeks. The bandage effect was examined after 7 and 14 days.

[Instability problems of the spine in sports].

In modern competitive sports the vertebral column is increasingly subjected to maximum stress. This has led to lasting damage especially in young competitive sportsmen in whom the vertebral column had not yet developed to full maturity. Back pain can be more successfully analysed in respect of its causes by means of the additional use of the knowledge and examination methods of manual medicine. Emphasis is placed in this article on the importance of such pain as an early symptom of ligamentous instability. Therapeutic recommendations are given.

[Synergism between joint mechanics and stump muscles in upper leg amputees. Arguments for a myotenodesis of the greater adductor muscle].

Stance- and swing-phase control of AK prostheses due to the development of new knee joint mechanics has been frequently discussed in the recent past. The functional anatomical principles of the thigh muscles will be presented, including the results of the most recent neurophysiological and biomechanical investigations. These conclusions lead to the discovery of obvious consequences in the modification of the above-knee amputation technique such as the fitting of AK prostheses.
