Kirschner Wires Combined With Elastic Tape for Multilayer Tension-Reducing Repair of a Large Stage 4 Pressure Injury of the Greater Trochanter: A Case Report

Background. Pressure injuries are common, difficult to manage, and carry a high economic burden. They are challenging to physicians and a burden to society. Case Report. An 89-year-old male, who had previously undergone internal fixation with screws and rods for a right intertrochanteric fracture, developed a deep circular open ulcer measuring 11 cm × 7.5 cm on his right hip after being bedridden for over 20 consecutive days because of symptoms of coughing and fatigue. Upon examination, the ulcer exhibited extensive necrotic tissue, purulent discharge, and a foul odor at its base. Following multiple debridement procedures, a multilayer tension reduction and repair surgery using the Kirschner wire technique in conjunction with elastic tape was performed on the 31st day of hospitalization. The wound achieved complete healing, and the patient was discharged on the 102nd day of admission. During the 6-month postoperative follow-up period, the appearance and sensory function of the wound skin were observed to have recovered satisfactorily. Conclusion. In this case, the use of Kirschner wires combined with elastic tape for multilayer tension reduction resulted in the repair of a large stage 4 pressure injury at the greater trochanter. The mechanism of action is discussed and analyzed to provide clinical evidence for such treatment.
