Desault bandage

The role of immobilization in the treatment of clavicular dislocations

In clinical practice, the treatment of acromioclavicular injuries can be either conservative or surgical. The conservative approach involves specialized external immobilization. Specifically, a thoracobrachial bandage equipped with a special compression screw (Shimbaretsky modification) is used. The main task of this design is to create constant external vertical pressure necessary to reliably maintain the pre-reduced dislocation in the anatomically correct position.

However, surgical treatment has a number of undeniable advantages. First, it is significantly more comfortable for the patient during the rehabilitation period. Second, surgery is recognized as the most reliable method for preventing re-displacement (recurrent dislocation). It is within the structure of postoperative patient management that the Desault bandage plays a key role, with its type and rigidity depending directly on the severity of the initial injury and the chosen surgical tactics.

Use in subluxations

When diagnosing an incomplete dislocation (subluxation) of the acromioclavicular joint, minimally invasive intervention becomes the method of choice. Surgeons prefer percutaneous transarticular pin fixation. During this procedure, the reduced end of the clavicle is stabilized using metal Kirschner wires (pins). This technique has proven to be the easiest to perform and the least traumatic for surrounding tissues.

Following successful percutaneous fixation, the rehabilitation stage begins, requiring adequate upper limb immobilization. In this case, the patient is indicated for application of a soft Desault-type bandage. The standard duration of wearing such a bandage is from four to six weeks. The most important clinical feature of this approach is that, thanks to reliable internal pin fixation, there is no need whatsoever to create additional external vertical pressure using the bandage components. The soft fixation serves only supportive and protective functions.

Management of complete dislocations

Patient management changes cardinally in the presence of a complete dislocation. In this situation, a prerequisite for successful treatment is the complete restoration of the damaged coracoclavicular ligament. To perform ligamentoplasty, surgeons can use both modern synthetic materials and the patient's own tissues (autologous tissue).

In addition to ligament repair, the combined technique requires additional stabilization of the injury zone. For this purpose, either plasty of the acromioclavicular joint (ACJ) itself or transarticular pin fixation of the clavicle is performed. Given the scale and complexity of such a combined intervention, the requirements for postoperative immobilization increase significantly. The patient is applied a rigid Desault plaster cast or a special abduction splint is used. The immobilization periods remain the same at four to six weeks, but the rigidity of the structure provides maximum rest for the integration of autologous tissues or synthetic implants.

When is the Desault bandage not required?

Despite the widespread use of the Desault bandage, there are modern surgical treatment methods that allow avoiding prolonged plaster immobilization in the postoperative period. We are talking about rigid fixation technologies, which initially provide the highest degree of biomechanical stability of the damaged segment.

Such advanced methods include the use of specialized devices with a "shape memory" effect. These implants are made of an innovative alloy—titanium nickelide. An alternative option for rigid stabilization is the use of a hook plate. Both of these techniques guarantee such reliable retention of the acromioclavicular joint that, as a rule, additional external fixation with a Desault plaster cast is not required for the patient. This significantly facilitates the early rehabilitation process and improves the quality of life in the postoperative period.
