This study investigated clinical outcomes of biomimetic mineralized collagen artificial bone putty for bone reconstruction in the treatment of calcaneus *** cases of calcaneal fractures surgically treated with open reduction and internal fixation in our hospital from June 2014–2015 were chosen and randomly divided into two groups,including 30 cases treated with biomimetic mineralized collagen artificial bone putty as treatment group,and 30 cases treated with autogenous ilia as control *** average follow-up time was 17.263.0 *** results showed that the surgery duration and postoperative drainage volume of treatment group were significantly lower than control group;there were no statistically significant differences in the fracture healing time,American Orthopaedic foot and ankle Society scores at 3 and 12 months after surgery,Bo¨hler’s angle,Gissane’s angle and height of calcaneus between the two *** were no significant differences in wound complication and reject reaction between the two groups,while significant difference in donor site *** a conclusion,the implantation of biomimetic mineralized collagen artificial bone putty in the open reduction of calcaneal fracture resulted in reliable effect and less complications,which is suitable for clinical applications in the treatment of bone defect in calcaneal fractures.

BACKGROUND Maisonneuve fracture is a special type of ankle fracture that consists of proximal fibular fracture,a lesion of the inferior tibiofibular syndesmotic complex(interosseous ligament,anterior inferior tibiofibular ligament and posterior inferior tibiofibular ligament),and injury of the medial structure of the ankle(deltoid ligament tear or medial malleolar fracture).The accepted mechanism of Maisonneuve fracture is pronation external rotation according to the Lauge-Hansen *** this paper,we report a rare pattern of Maisonneuve fracture,which has the characteristics of both pronation external rotation ankle fracture and supination adduction ankle *** SUMMARY A 31-year-old female patient accidentally sprained her right ankle while walking 5 d before hospitalization in our *** patient was initially missed in other hospitals and later rediagnosed in our outpatient ***-length radiographs of the lower leg revealed proximal fibula fracture,inferior tibiofibular joint separation,and medial malleolar fracture involving the posterior malleolus,which was also revealed on computed tomography *** resonance imaging revealed rupture of the anterior inferior tibiofibular ligament and anterior talofibular *** diagnosed a rare pattern of Maisonneuve fracture with proximal fibular fracture,inferior tibiofibular joint separation,medial malleolar fracture and ruptures of the anterior inferior tibiofibular ligament and anterior talofibular *** patient underwent open reduction and internal fixation in our hospital.A 6-mo postoperative follow-up confirmed a good clinical *** To our knowledge,this rare pattern of Maisonneuve fracture has not been previously *** possible mechanism of injury is supination adduction combined with pronation external *** analysis of the injury mechanism of Maisonneuve fracture is of great clinical significance and can better guide clinical treatm
