RESUMO
Objective: To explore the morphological classification and clinical significance of scapular spine based on CT three dimensional reconstruction. Methods: The scapular spines of 280 adults in the Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University were classified by CT plain scan and three-dimensional reconstruction, and its guiding significance for clinical work was discussed. Measurement content the distance between the seven structures of the scapular region and the thickness of the nine points. Results: Under the CT 3D reconstruction, the scapular spines were divided into five types: thin shape, wood rod shape, thick shape, fusiform shape and S shape. There were 14 cases of thin shape, accounting for 14.64%; and 63 cases of wood rod shape, accounting for 22.50%; and 78 cases of wood rod shape, accounting for 27.86%; and 89 cases of thick shape, accounting for 27.86%; and 89 cases of fusiform shape, accounting for 31.7p%, and 9 cases of S shape, accounting for 3.21%. In the thin shape, the thickness of B (9.36±3.61) mm was obviously thinner than the other four types (P<0.05); In thick shape, the length of AC (84.36± 6.00) mm and AD (84.36±6.00) mm was longer than the other four types, and the thickness of F, H, I, K was the thickest (P<0.05); In the fusiform shape, the length of BC was the shortest, and the thickness of K was the thinnest except for the thin shape (P<0.05). Conclusion: Under the CT 3D reconstruction, the scapular spines are divided into five types; thin shape, wood rod shape, thick shape, fusiform shape and S shape. Among them, fusiform shape is the most, and S shape is the least; The scapular spine of thick shape is the most abundant bone, which is the high quality source of autologous bone graft, and can also be used as a better fixed position for internal implants. On the contrary, the scapular spine of thin shape has the least amount of bone, and the internal fixation strength is relatively poor. Different types of scapular spines have certain effects on their operative method.
RESUMO
Objective To provide applied anatomic bases for the transplantation of scapular spine bone flap pedicled with supraspinous branch of suprascapular artery Methods The origin,course,branches and distribution were observed on 30 adult cadaver specimens;the operative designs were imitated on 6 specimens Results The supraspinous branch originated from suprascapular artery,went between supraspinatus muscle and scapular bone medially,and divided into 3～4 periosteal branches to scapular spine with a diameter of 0 5～0 8mm The length of stem of supraspinous branch was (4 8?0 6)cm Conclusions The transplantation of scapular spine bone flap pedicled with supraspinous branch of suprascapular artery is feasible
