Clinical anatomical study of pedicled vascularised scapular bone graft using the angular branch.
This study is an anatomical investigation of the angular branch of thoracodorsal artery, and examines the possible range of clinical targets for pedicled vascularised scapular bone graft. Forty-six cadavers were studied. The blood vessel length was calculated, and the distance required to reach the distal humerus from the lower end of the articular surface of the humeral head as reference point was compared with bone length. The length from reference point was an average of 121.7 mm. It was thought that the maximum distance to arrive in reference point to the distal humerus was a total of blood vessel length and transplantation bone length, which was an average of 246.3 mm. This was longer than the average of 240.8 mm of bone length from reference point to humeral medial condyle. This study had confirmed that a pedicled vascularised scapular bone graft using the angular branch could be transplanted to the distal humerus.
