Background:
Patients with advanced ankle arthrosis or joint deformities and co-existing lower limb shortening present a complex therapeutic problem. This paper presents the Ilizarov treatment as a comprehensive method of simultaneous ankle arthrodesis and equalisation of lower limb length in 18 patients.
Material And Methods:
Eighteen patients with arthrosis, deformities or other conditions of the ankle joint and ipsila-teral lower limb shortening were treated with the Ilizarov method. The patients were assessed with the Foot and Ankle Outcomes Questionnaire before the treatment and one year after Ilizarov Fixator removal.
Results:
The Ilizarov Fixator allows early weight-bearing of the operated limb, which is undoubtedly convenient for the patient. The mean treatment duration was 8.2 months (range 4-18 months). Lower limb lengthening was 4.1 cm on ave-rage (range 2.5-8.5 cm). Bone union was achieved in all cases. Radiological and clinical outcomes were satisfactory in all 18 cases. Prolonged regenerate calcification was recorded in 1 patient. Ten patients developed soft tissue pin-tract infec-tions and in 1 patient the Kirschner wire broke. According to the Foot and Ankle Outcomes Questionnaire, patients achiev-ed a notable improvement in daily functioning and quality of life.
Conclusions:
1. The outcomes of a comprehensive treatment con-sisting of ankle arthrodesis and lower-leg leng-then-ing using the Ilizarov method confirm its effec-tiveness. 2. The Ilizarov Fixator allows early weight-bearing of the operated limb and evaluation at all treat-ment stages, creating an optimal biological envi-ron-ment for bone healing. 3. The patient recovers functionally to allow satis-fac-tory and pain-free functioning as well as re-sum-ption of daily responsibilities. The low inci-den-ce of complications adds to the attractiveness of the method.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
