Fitting of electronic elbow on an elbow disarticulated patient by means of a new surgical technique.
Rehabilitation of trans-humeral amputees represents a challenge. One of the difficulties to overcome is prosthetic suspension. In the case of elbow disarticulation the presence of humeral condyles permits better suspension, but there is no room for elbow joints, particularly electronic ones, and the only available mechanisms are provided by external hinges. The purpose of this report is to present a case of a primarily elbow disarticulated patient, with indication for surgical revision due to bad skin coverage, neuroma and the wish to improve prosthetic fitting. The surgical plan outlined was to produce a shortening of the humerus, by means of an osteotomy just above the humeral condyles, preserving them for prosthetic suspension. This bone reduction was carried out with complementary shaping of bone segments with an indentation to enhance fixation. The operation was completed with neuroma resection, myodesis and removal of the skin grafted area. Preservation of the humeral condyles actually produced effective suspension. For final fitting a Utah Arm II was used, with wrist rotator, and interchangeable hand and Greifer for terminal devices. Good initial results and at nine months follow-up suggest this procedure should be considered in other elective situations.
