About the Majicast

The Majicast is an instrument that will revolutionize the way that orthopaedic specialists produce prosthetic sockets. Innovative Dutch engineering has produced a product that accurately reflects the contours of a patient’s unique shape and volume of their residual limbs. The result is a tailor made fit that increases comfort and reduces the necessity for further modification in the future.

The collaboration

The Majicast was originally invented by Arjan Buis from the Strathclyde University in Glasgow in 2005. Over the last years it was used to supply 300 prostheses to war victims in North Iraq, and it was tested in Tanzania. Tests showed that a couple of improvements still needed to be made to the original prototype. These improvements is agency REGGS in Amsterdam currently smartly integrating in the optimised prototype, assisted by Arjan Buis.

 

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, 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 prosthesis 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 prosthesis and increased patient satisfaction.

 

The casting process – how does it work?

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.

Product features

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.

Patented technology

Developed by the Biomechanical Department of Strathclyde University (Glasgow, Scotland) since 2005, and designed by Dutch-based design engineering agency Reggs, the product has been patented.

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.    

Self-sufficient, stand-alone system

The Majicast does not 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.

Innovative soft tissue control system

For achieving a corrected soft tissue displacement on patients’ limbs that guarantees the creation of anatomically corrected plaster cast shapes.

Ergonomic design

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

 

Benefits

Accurate and consistent results

Majicast’s resulting casts make it possible to reduce the need for modification of the resultant positive mold, hence the reduction of socket rectification times. An additional benefit is that the patient can walk again with its new prosthesis in a shorter time.

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 potentially lead to the production of well-fitting sockets – whether for use with different type of liners, soft inserts or socks for a wide variety of residual limbs.

Patient comfort and better fit

Prosthetic sockets produced with Majicast casts will potentially have increase user comfort, stability and fit; achieved by reduced shear and friction at the socket/limb interface which leads to prosthesis improved 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 simplify certification procedures.
