There is a broad range of lumbar pedicular and neural arch anomalies, with spina bifida occulta and spondylolysis being especially common. It is very rare for a pedicular cleft to be associated with contralateral spondylolysis in the same vertebral segment. We observed L4 spondylolisthesis, clefting of the left L4 hypertrophied pedicle associated with contralateral spondylolysis, and spinal stenosis on a radiographic study of the lumbar spine. Operative treatment was performed, with posterior decompression, partial removal of the hypertrophied pedicle, posterior lumbar interbody fusion using a cage, and posterior instrumentation. The patient's neurologic symptoms resolved after operative treatment. Fusion of the left pedicle cleft was observed on 6-month follow-up CT. We report one case of pedicular cleft fusion using pedicle screw fixation and present a review of the relevant literature.

PURPOSE: Several treatment options have been reported for post-traumatic kyphosis (PTK) and neurologically compromised osteoporotic fractures. However, there is no ideal surgical procedure. This study evaluated the effectiveness of posterolateral decompression and anterior support with a titanium mesh in PTK by posterior surgery. MATERIALS AND METHODS: Seventeen patients with PTK and neurologically compromised osteoporotic fractures underwent a single posterior approach. During posterior decompression, a titanium mesh was inserted through the posterior approach after a transpedicular intracorporeal corpectomy. Complications, operating time and blood loss were noted, and radiographic studies and neurological status were evaluated before surgery, after surgery, and at final follow-up. RESULTS: The mean kyphosis was 35+/-9.7degrees (range; 17-58degrees) before surgery, 3.2+/-1.8degrees after surgery (correction; 90.5%) and 5.5+/-3.2degrees at the final follow-up (correction; 85.5%). There was 29.6degrees correction of the kyphosis with a 6% loss of correction. Postoperative neurological improvement using the Frankel classification was demonstrated in all patients. There was no new onset or progressive neurological deterioration, additional surgery or extrusion of mesh. Three complications were encountered: one care each of pneumonia, prolonged ventilator support and distal adjacent vertebral fracture. CONCLUSION: The posterior insertion of a titanium mesh for anterior support appears to maintain the length of the anterior column, stabilize the injured vertebra and facilitate spinal fusion. Posterolateral decompression allows as direct a decompression as the anterior approach.

PURPOSE: Next-generation sequencing (NGS) allows simultaneous sequencing of multiple cancer susceptibility genes and may represent a more efficient and less expensive approach than sequential testing. We assessed the frequency of germline mutations in individuals with epithelial ovarian cancer (EOC), using multi-gene panels and NGS. MATERIALS AND METHODS: Patients with EOC (n=117) with/without a family history of breast or ovarian cancer were recruited consecutively, from March 2016 toDecember 2016.GermlineDNAwas sequenced using 35-gene NGS panel, in order to identify mutations. Upon the detection of a genetic alteration using the panel, results were cross-validated using direct sequencing. RESULTS: Thirty-eight patients (32.5%) had 39 pathogenic or likely pathogenic mutations in eight genes, including BRCA1 (n=21), BRCA2 (n=10), BRIP1 (n=1), CHEK2 (n=2), MSH2 (n=1), POLE (n=1), RAD51C (n=2), and RAD51D (n=2). Among 64 patients with a family history of cancer, 27 (42.2%) had 27 pathogenic or likely pathogenic mutations, and six (9.3%) had mutations in genes other than BRCA1/2, such as CHECK2, MSH2, POLE, and RAD51C. Fifty-five patients (47.0%) were identified to carry only variants of uncertain significance. CONCLUSION: Using the multi-gene panel test, we found that, of all patients included in our study, 32.5% had germline cancer-predisposing mutations. NGS was confirmed to substantially improve the detection rates of a wide spectrum of mutations in EOC patients compared with those obtained with the BRCA1/2 testing alone.
