Hydrostatic casting device An instrument for use by orthopaedic specialists to capture the shape and volume of residual limbs, for the production of well-fitting transtibial prosthetic sockets - reducing rectification times, whilst patient fit, comfort and work efficiency increases.

Product description The working principle behind the Majicast is hydrostatic pressure. This means that water pressure is used for modeling the casting material, by deforming the soft tissue of the residual limb under a uniform load. This results in a corrected soft tissue displacement that allows capturing an accurate impression of the volume and bone structures of the residual limb for creating and fitting total surface bearing (TSB) sockets. Using a standardized, easily documented procedure,

Product features

• PATENTED TECHNOLOGY

Developed by the Biomechanical Department of Strathclyde University (Glasgow, Scotland), and designed by Dutch-based engineering agency REGGS.

• HYDROSTATIC LOADING CONDITION Equal distribution of weight bearing forces on the surface of the limb is successfully transmitted with high fidelity to the casting material so full contact is achieved.

• INNOVATIVE SOFT TISSUE CONTROL SYSTEM Achieving a corrected soft tissue displacement on patients’ limbs that guarantees the creation of anatomically correct casts.

the Majicast is proven to provide accurate and consistent results, making it possible to eliminate the need for modification of the resultant positive mold, reducing delivery times and socket manufacturing costs. Prosthetic sockets produced as a result of the Majicast process have increased user comfort, stability and fit; achieved by reduced shear and friction at the socket/residual limb interface which leads to improved control of the prosthetics and increased patient satisfaction.

• ERGONOMIC DESIGN For specialists and patients’ ease-of-use and convenience, the Majicast simplifies the casting process into well-defined steps while increasing efficiency.

• SELF-SUFFICIENT, STAND-ALONE SYSTEM The Majicast doesn’t rely on external water or power sources. Its quick-filling mechanism facilitates setting up the Majicast for the first time, after which it will remain completely independent from any water and energy supply.

The casting process The Majicast captures the unique shape of lower residual limbs with the use of plaster bandages or other direct casting material. Once the casting material is applied, the clinician instructs the patient to insert the limb in the Majicast, and then to transfer his/her full body weight to the inserted limb while remaining in a standing position.

Under the patient’s full body weight, the residual limb is loaded with uniform water pressure while the casting material cures. This creates an advantageous hydrostatic loading condition, such that the stiffest path principle is achieved and deep shear stresses are minimized. Hence the resulting lower limb cast captures the actual anatomy of a patient’s residual limb. This is how the perfect fit is achieved: by producing accurate lower limb impressions for the efficient production of comfortable prosthetic sockets.

Sequence of use

Benefits

• SUPERIOR VERSATILITY With the Majicast you can produce accurate lower limb casts with the use of plaster of Paris or other direct casting material, for manufacturing transtibial prosthetic sockets.

• HIGH COMPATIBILITY Using the Majicast leads to the production of wellfitting sockets –whether for use with different type of liners, soft inserts or socks for a wide variety of residual limbs.

• ACCURATE AND CONSISTENT RESULTS Majicast’s resulting casts make it possible to eliminate the need for modification of the resultant positive mold, hence reducing socket rectification times.

• PATIENT COMFORT AND BETTER FIT Prosthetic sockets produced with Majicast casts have increased user comfort, stability and fit; achieved by reduced shear and friction at the socket/limb interface which leads to improved prosthetic control and patient satisfaction.

• EASY IMPLEMENTATION With little time and practice, the Majicast can be successfully adopted and implemented in your current practice, thanks to its training program and well-documented procedure that simplifies certification procedures.
