Between 1981 and 1987, Stewal, in collaboration with KU Leuven, developed an innovative system to custom-fabricate hip prostheses during surgery tailored to the patient. From 1987 to 2010, Stewal developed and manufactured an average of 300 such custom hip prostheses per year for Professor Orthopedics Mulier at UZ Leuven, Campus Pellenberg. Additionally, we served as a partner for various specific surgical instruments and equipment.

Stewal is also frequently consulted for projects involving other surgical instruments and implants, such as in the fields of dentistry, aesthetic surgery, facial, and cranial surgery...
