Total elbow arthroplasty with tricep turn-down flap in an old unreduced elbow dislocation: A case report

INTRODUCTION AND IMPORTANCE: The treatment preference for neglected elbow dislocation is by open reduction and lengthening the tricep muscle. If the dislocation is not reduced for more than 6 months, degenerative resorption would have occurred. We did total elbow arthroplasty (TEA) with a tricep turn-down flap for the management in this case. The use of a tricep flap for tricep shortening after unreduced elbow dislocation has been reported in previous publications but none used a turn-down flap. CASE PRESENTATION: An 82-year-old woman came to the orthopedic outpatient clinic with pain and discomfort on her right elbow. The arm affected by the injury was her dominant hand, restricting her from farming and leisure activities. Exploration findings confirmed the presence of a dislocated elbow with associated soft tissue complications. The cartilage was degeneratively destructed, and the tricep muscle was retracted. CLINICAL DISCUSSION: In our case, tricep shortening was managed with elongation using a turn-down flap. The lack of soft tissue layers and thin fibrous fascias results in tension-vulnerable TEA surgical wounds. This is caused by the insufficient coverage of the joint, which leads to wound complications. Previous studies of turn-down flap procedures showed good flap survival and functional outcomes. CONCLUSION: Tricep turn-down flap could be an option for tricep lengthening procedures in unreduced neglected elbow joint dislocation.
