Shoulder disarticulation is one of the upper limb amputation levels in which the arm is lost entirely from the shoulder joint, and shoulder disarticulation prosthesis applications for this level are covered as a separate topic. Because shoulder, elbow, wrist and hand functions are all affected at this level, prosthetic fitting requires individual planning and a long adaptation process. Applications are carried out in line with the specialist physician's report and prescription.
Types of prostheses
Different prosthetic approaches may be considered for losses at shoulder level:
- Cosmetic prostheses: Prostheses whose primary aim is to provide the natural appearance of the arm, with low expectations of functional movement; the process of making cosmetic prostheses can be reviewed separately.
- Body-powered prostheses: Mechanical solutions that work through cable systems driven by body movements.
- Myoelectric (muscle-controlled) prostheses: Electronic systems that produce movement using electrical signals picked up from the muscle surface, explained in detail under myoelectric arm prostheses.
- Combined (hybrid) systems: Solutions in which body power and electronic control are used together.
Adaptation and rehabilitation
With prostheses at this level, weight and learning the movements are factors that can affect the process of use. For this reason, it is important that prosthesis use is carried out with physiotherapy support. Regular exercise, muscle training and gradual use can make it easier to adapt the prosthesis to daily life.
Technological developments
Upper limb prosthetic technology continues to develop. For losses at this level, surgical techniques such as targeted muscle reinnervation (TMR) may be used to make prosthetic control easier; research continues on new systems based on the control of nerve and muscle signals. Which type of prosthesis is appropriate is determined according to the person's health, muscle structure and the physician's assessment.
