Teardrop fracture of axis is rarely seen, especially the huge type. The surgical approach is controversial and individualized in the literature. We reported a special case to share our experience of anterior hollow screw fixation combined with posterior unilateral lateral mass screws fixation to treat a huge teardrop fracture of the axis (HTDFA). A 42-year-old male was referred to our department; he presented neck pain after a vehicle accident. Neck movement was limited with no neurological compromise. Cervical x-rays showed a huge tear drop fracture of the anterior–inferior corner of the axis,the lower cervical spine degeneration and poor cervical curvature. Cervical CT confirmed the avulsed ratio of inferior endplate of axis up to 62%. Cervical MRI showed the anterior longitudinal ligament disruption associated with disk injury and instability of C2-3. In order to save the motion segment of C2-3 and decrease the possibility of lower cervical degeneration if C2-3 fusion occurs, a surgical plan involving anterior reduction, hollow screw fixation combined with posterior unilateral mass screws fixation was performed. The 3 months postoperative x-ray and CT scan showed the tear drop fragment had completely healed. The internal fixations were removed timely for 6 months after surgery. The patient had an excellent function of cervical spine without any clinical symptoms. The 12 months postoperative X-ray showed radiographic union of the bony fragment and a good motion range without any instability. We conclude that anterior hollow screw fixation combined with posterior unilateral lateral mass screws fixation can be the treatment of choice for HTDFA
A B S T R A C TGout is a rare cause of patellar fracture, with few documented cases. We report a case of gout tophi in the patella, the severe transverse fracture resulting from minor trauma. The patient was managed by the same treatment principles used for patients with nonpathologic patella fractures. We preformed excising the mass, fixing the bone fragment and filling in bone defect with allograft bone. Union of the fracture was seen at three months follow-up. The patient has recovered completely and returned to his former work after 3 months postoperatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
