OBJECTIVE: To observe and compare the shoulder joint function, complications and clinical effects of hemiarthroplasty and open reduction and locking plate in the treatment of comminuted proximal humeral fracture (Neer IV) with 3D printing technique.
METHODS: From March 2012 to April 2018, 31 middle age and elderly patients with comminuted proximal humeral fractures (Neer IV) were treated, including 4 males and 27 females, aged from 55 to 94 years old with an average age of 71 years, with a course of 1 to 3 years. Among them, 20 cases were treated with open reduction and locking plate internal fixation (ORIF group) and 11 cases were treated with lower half shoulder replacement (HA group) assisted by 3D printing technology. Using CT data and Mimics software of Materialise Company in Belgium, the reconstruction of fracture was simulated on computer. The height of fracture end to humeral head, the height of tubercle to humeral head, the angle of humeral head backward obliquity were measured to assist the hemiarthroplasty. Follow-up and X-ray examination were performed, the incidence of complications were observed, and Neer score was used for the shoulder joint function.
RESULTS: Thirty-one patients were followed up for 1 to 3 years with an average of 2 years. In HA group, there was no prosthesis loosening, fracture and subsidence, the head of artificial humerus was intact, the fracture of nodules and nodules did not heal in 1 case, Neer score was 84.18±3.55; in ORIF group, there were 8 cases of proximal humerus bone resorption, 1 case of fracture nonunion, 1 case of internal fixation loosening, Neer score was 55.91±10.78; there was significant difference in Neer score of shoulder joint function between the two groups(P<0.05).
CONCLUSIONS: Ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures, which promise minimal incision, protect sural nerve, ensure quality of tendon anastomosis and fixation, and is a ideal method for repairing acute closed Achilles tendon ruptures.
