Avulsion fracture of the occipital condyle are rare lesion at craniovertebral junction. It is often related to high-energy traumatic injuries and show diverse clinical presentations. Neurologic deficit and instabilities may justify surgical treatment. However, the integrity of neurovascular structures is undervalued in the current literatures. In this case report, we described a 26-year-old female patient with avulsion fracture of occipital condyle following a traffic accident. On initial presentation, her Glasgow Coma Scale was 8. She presented with fracture compound comminuted depressed, on the left side of her forehead with skull base fracture extending into clivus and occipital condyle. Her left occipital condyle showed avulsion injury with displacement deep into the skull base. On her computed tomography angiography, the displaced occipital condyle compressed on the sigmoid sinus resulting in its obstruction. While she was recovering her consciousness during her stay in the hospital, the lower cranial nerves showed dysfunctions corresponding to Collet-Sicard syndrome. Due to high risk of vascular injury, the patient was conservatively treated for the occipital condyle fracture. On the 4 months postdischarge follow-up, her cranial nerve symptoms practically recovered, and the occipital condyle showed signs of fusion without further displacement. Current literatures focus on neurologic deficit and stability for the surgical decisions. However, it is also important to evaluate the neurovascular integrity to assess the risk of its manipulation as it may result in fatal outcome. This case shows, an unstable avulsion occipital condyle fracture with neurologic deficit can be treated conservatively and show a favorable outcome.

AbstractAbstract PDF

Cranioplasty (CP) is often required for survival after decompressive craniectomy. Several materials, including autologous bone and various artificial materials, have been introduced for CP, but it remains unclear which material is best for CP. This study aimed to explore differences in complications between patients who underwent CP using an autologous bone flap versus a three-dimensional (3D) titanium mesh and to identify significant risk factors for post-CP complications.


In total, 44 patients were enrolled in this study and divided into two groups (autologous bone vs. 3D titanium mesh). In both groups, various post-CP complications were evaluated. Through a comparative analysis, we aimed to identify differences in complications between the two groups and, using binary logistic analysis, to determine significant factors associated with complications after CP.


In the autologous bone flap group, there were three cases of surgical infection (3/24, 12.5%) and 11 cases of bone flap resorption (BFR) (11/24, 45.83%). In the 3D titanium mesh group, there was only one case of surgical infection (1/20, 5%) and 11 cases of various complications, including mainly cosmetic issues (11/20, 55%). A subgroup risk factor analysis of CP with an autologous bone flap showed no risk factors that predicted BFR with statistical significance, although a marginal association was found between larger bone flaps and BFR (odds ratio [OR]=1.037, p=0.090). In patients treated with a 3D titanium mesh, multivariate analysis revealed that only the existence of a ventriculo-peritoneal shunt system was strongly associated with overall post-CP complications (OR=18.66, p=0.021).


Depending on which material was used, different complications could occur, and the rate of complications was relatively high in both groups. Hence, the material selected for CP should be selected based on individual patients’ conditions.
