The goal of this study was to demonstrate the incidence of fusion and soft-tissue swelling in multilevel anterior cervical discectomies and fusions (ACDFs) using polyetheretherketone (PEEK) spacers with recombinant human bone morphogenetic protein-2 (rhBMP-2) impregnated in a Type I collagen sponge and titanium plates.

Abstract
BACKGROUND: The assessment of residual symptoms after endoscopic sinus surgery for nasal polyposis (NP) could be an accurate way to evaluate surgical outcomes.
OBJECTIVE: To assess the residual symptoms and their severity at 6 weeks and 7 months after radical ethmoidectomy for NP.
METHODS: Sixty-five patients who had surgery for NP were included in this prospective study. Six residual symptoms (nasal obstruction, anterior rhinorrhea, postnasal discharge, olfactory disturbances, facial pain, and cough) were assessed by using the validated Dysfonctionnement Nasal Chronique (French) or Chronic Nasal Dysfunction (English) questionnaire at 6 weeks and 7 months after surgery. Olfactory measurements were performed with the Sniffin’ Stick test. A self-rating score of ≥1 was considered as “having a complaint.”
RESULTS: Radical ethmoidectomy for NP improved not only the number of symptoms but also the intensity of symptoms. Before surgery, 64 of 65 patients (98.46%) reported at least three of the six symptoms, whereas 26 patients (40%) reported six symptoms, 16 (24.62%) reported five symptoms, and 14 (21.54%) reported four symptoms. At 6 weeks and at 7 months after surgery, one-third of the patients had fewer than three symptoms. Olfactory disturbance remained the most mentioned postoperative disabling problem. Posterior discharge tended to become more pronounced at 7 months than at 6 weeks after surgery but remained considerably improved compared with the preoperative state.
CONCLUSION: This information is useful to warn patients about the difficulty of getting rid of all symptoms and that there is a chance that some symptoms remain or even reappear after NP surgery.

Abstract
PURPOSE: The aim of this study is to evaluate the efficacy of posterior indirect reduction and pedicle screw fixation without laminectomy for the treatment of Denis type B thoracolumbar burst fractures with incomplete neurologic deficit.
METHODS: From March 2008 to May 2012, 36 consecutive patients of Denis type B thoracolumbar burst with incomplete neurologic deficit were enrolled. All of the patients accepted the treatments of posterior indirect reduction and pedicle screw fixation without laminectomy. Clinical and radiologic outcomes were assessed preoperatively and postoperatively.
RESULTS: Operations were performed in a relatively short time without massive hemorrhage. Their neurologic functions were improved by at least one Frankel grade. The average score of American Spinal Injury Association (ASIA) motor increased from 25.4 ± 10.8 to 42.1 ± 10.5, and the recovery rate of the ASIA score was also increased. The pain level was relieved for all the patients. The local kyphosis angle was reduced from 25.9° ± 3.4° to 6.9° ± 2.2° (P <0.05) and remained 7.9° ± 2.0° (P > 0.05) at the latest follow-up. After the operation, the mean vertebral canal diameter increased from 5.5 ± 1.3 to 11.1 ± 2.2 mm (P < 0.05) and the mean canal stenosis index increased from 32.9 ± 7.8 to 84.8 ± 7.3% (P < 0.05). There were no serious complications and fixation failures during follow-up.
CONCLUSION: Denis type B thoracolumbar burst fractures with incomplete neurologic deficit can be effectively treated by posterior indirect reduction and pedicle screw fixation without laminectomy.
