Introduction. Osteoporotic vertebral fracture treatment options include vertebroplasty, in which development of new fractures is among the possible complications which may develop during the postoperative period. We aim to evaluate whether or not postoperative mobilization time has effect on occurrence of new fractures. Materials and Methods. A total of 126 patients, consisting of 30 (39.7%) males and 96 (60.3%) females, who underwent sedation-assisted vertebroplasty under local anesthesia between January 2014 and June 2017 were retrospectively evaluated. Preoperative and postoperative visual analogue scores (VASs) and mobilization time (hours) were assessed. Day of new fracture occurrence during follow-up was assessed. Results. The mean follow-up period was 9 months (7–13 months). The most common fracture segment was the L1 vertebra (15.9%). The preoperative VAS was 8.29 ± 0.95, and the postoperative VAS was 2.33 ± 0.91. The change in VAS was statistically significant (p=0.01, p<0.05). Of all the patients, 21 (16.66%) had developed new fractures. No statistical difference was observed between mobilization time (hours) and formation of new fractures (p=0.48, p>0.05). Conclusion. We came to the conclusion that mobilization time (hours) was not a risk factor in the development of new fractures. In addition, there is no relationship between mobilization time and localization of new fractures.

Η κύφωση από ένα οστεοπορωτικό σπονδυλικό κάταγμα θεωρείται παράγοντας κίνδυνου για νέα κατάγματα, ιδιαίτερα στους παρακείμενους σπονδύλους. Όμως, ο ρόλος της παραμόρφωσης της τελικής πλάκας δεν έχει εκτιμηθεί. Η παρούσα μελέτη ελέγχει την υπόθεση ότι η αλλαγή στις μηχανικές ιδιότητες του μεσοσπονδύλιου δίσκου μετά από κάταγμα της τελικής του πλάκας, ακόμη και επί απουσίας κύφωσης, αλλάζει την μεταφορά φορτίων και προδιαθέτει σε παρακείμενα σπονδυλικά κάταγμα. Χρησιμοποιήθηκαν οκτώ ανθρώπινα θωρακοσφυϊκά παρασκευάσματα, αποτελούμενα από πέντε σπονδύλους. Για την επιλεκτική θραύση της μίας τελικής πλάκας του μεσαίου σπονδύλου δημιουργήθηκε κενό στο σπογγώδες οστό κάτω από την τυχαία επιλεγμένη πλάκα και το παρασκεύασμα συμπιέστηκε σε θέση κάμψης. Στη συνέχεια εφαρμόστηκε ροπή έκτασης υπό συμπιεστικό φορτίο 150 Ν, η οποία αποκατέστησε το ύψους του πρόσθιου τοιχώματος και την κυφωτική παραμόρφωση του σπονδυλικού σώματος, ενώ η τελική πλάκα παρέμεινε σημαντικά παραμορφωμένη. Το σπονδυλικό σώμα πληρώθηκε στην αναταγμένη θέση με πολυμεθακρυλικό τσιμέντο μετά τον προσεκτικό καθαρισμό του από τις οστικές δοκίδες ώστε να διασφαλιστεί η ομοιόμορφη κατανομή του τσιμέντου κάτω από τις τελικές πλάκες. Κάθε παρασκεύασμα ελέγχθηκε σε κάμψη και έκταση (ροπή ±6 Nm) υπό φορτίο 400 Ν, ενώ γινόταν καταγραφή της πίεση στους δίσκους άνω και κάτω του μεσαίου σπονδύλου και της τάσης (strain) στο πρόσθιο τοίχωμα των παρακείμενων σπονδύλων. Η πίεση των δίσκων στα άθικτα παρασκευάσματα αυξήθηκε κατά την κάμψη κατά 26 ± 14%. Μετά την ενίσχυση με τσιμέντο η πίεση των δίσκων κατά την κάμψη αυξήθηκε κατά 15 ± 11% στους δίσκους με άθικτη τελική πλάκα, ενώ μειώθηκε κατά 19,0 ± 26,8% στους δίσκους με παραμορφωμένη τελική πλάκα. Κατά την κάμψη, η συμπιεστική φόρτιση στο πρόσθιο τοίχωμα του σπονδύλου που βρισκόταν δίπλα από την παραμορφωμένη πλάκα αυξήθηκε κατά 94,2 ± 22,8% σε σχέση με τα άθικτα παρασκευάσματα (p<0,05), ενώ δεν άλλαξε σημαντικά στο σπόνδυλο δίπλα στην μη παραμορφωμένη πλάκα (18,2 ± 7,1%, p>0,05). Επακόλουθη κάμψη με συμπίεση προκάλεσε παρακείμενα κατάγματα δίπλα από την παραμορφωμένη πλάκα σε έξι παρασκευάσματα και μη παρακείμενο κάταγμα σε ένα, ενώ σε άλλο ένα παρασκεύασμα δεν παρατηρήθηκε νέο κάταγμα.Στους δίσκους με ακέραιες τελικές πλάκες η πίεση του πυρήνα αυξάνεται κατά την κάμψη αποτρέποντας την υπερβολική συγκέντρωση φορτίου στο πρόσθιο τοίχωμα. Ο αυξημένος χώρος που διατίθεται στον πυρήνα μετά από ένα οστεοπορωτικό κάταγμα επηρεάζει την ικανότητά του να κατανέμει το φορτίο και αναγκάζει τον ινώδη δακτύλιο να μεταφέρει περισσότερο φορτίο κατά την κάμψη, με αποτέλεσμα την υπέρμετρη καταπόνηση του πρόσθιου τμήματος του παρακείμενου σπονδύλου που προδιαθέτει σε κάταγμα ακόμη και μετά από διόρθωση της κύφωσης. Η παρούσα μελέτη υποδεικνύει ότι η διόρθωση της παραμόρφωσης της τελικής πλάκας μπορεί να έχει ρόλο στη μείωση του κινδύνου παρακείμενων καταγμάτων.

Background: Different laser types have been used for the treatment of hypertrophied inferiornasal turbinates. The clinical experiences of its treatment by means of a diode laser are presented.Methods: A total of 45 patients suffering from nasal obstruction due to hypertrophied inferiorturbinates (HIT) were treated with a continuous diode laser (14 W- 940 nm) in "contact" modeand under local anesthesia. Thirty patients (16 with allergic rhinitis and 14 with vasomotorrhinitis) were included into this clinical trial with a follow-up of 6 months. The study wasconducted by a questionnaire, photo documentation, conventional radiology of the paranasalsinuses, and histology.Results: The mean operation time took 8 min/turbinate, no nasal packing was necessary andno immediate complications (e.g., bleeding) were observed. Statistical analysis revealedsignificant subjective improvement (86%) of the nasal airflow and nasal cavity volume (photodocumentation) 6 months after laser surgery. In addition, complete relief of headache wasachieved in 32%. The remission rates of persistent rhinorrhoea and post-nasal dripping were,at about 88% and 64%, respectively. Atrophic change and synechiae had not been observed.Conclusions: Diode laser treatment of HIT is a useful procedure, which can be performed as anoutpatient surgery under local anesthesia, resulting in a controlled coagulation and ablation of thesoft tissue. The short operation time and the good results provide an excellent patient acceptance.Key words: Diode Laser; Hypertrophied Inferior Turbinate; Turbinoplasty.DOI: 10.3329/bjo.v16i1.5778Bangladesh J Otorhinolaryngol 2010; 16(1): 29-34

Category: Bunion Introduction/Purpose: Hallux valgus is a common deformity of the forefoot. There are over 130 procedures described to correct hallux valgus. Classically, the treatment of mild to moderate hallux valgus is with a distal metatarsal osteotomy. A variety of fixation techniques have been described for use with this osteotomy most of which require partial or non-weight bearing until the osteotomy is healed. Tension Band fixation is a well-known principle in orthopedic surgery. The goal of the present study is to radiographically assess the maintenance of distal first metatarsal osteotomy fixation using a novel tension band device (Re+Line tension band bunion plate system, Nextremity Solutions) with immediate post-operative weight-bearing. Methods: The patient database for one surgeon was retrospectively reviewed for patients that underwent hallux valgus correction with the Re+Line tension band device between 2014 and 2017. Postoperative protocol included a soft dressing, firm surgical shoe, and weight-bearing as tolerated with a cane. Patients were excluded if fixation was achieved with something other than a tension band construct. Radiographs were obtained and reviewed retrospectively by 3 authors. Pre and postoperative hallux valgus (HVA) and intermetatarsal angles (IMA) were measured as described previously in the literature, and the changes in correction compared. Maintenance of correction and hardware integrity were assessed at final follow-up after weight bearing as tolerated in a surgical shoe in the postoperative period. Statistical analysis was performed using a Wilcoxon signed-rank test for the changes in HVA and IMA. Results: There was a total of 72 patients and 76 toes that underwent hallux valgus correction with a tension band construct, at a mean follow-up of 4.36 months. 68 of 72 patients were female. The average age was 60.8 years old. The mean preoperative HVA was 27.1 degrees. The mean postoperative HVA was 6.14 degrees, with a mean correction of 20.22 degrees (p<0.001). The mean preoperative IMA was 14.14 degrees. The mean postoperative IMA was 6.10 degrees, with a mean correction of 7.98 degrees (p<0.001). There was loss of reduction found in 6 of 76 toes (7.89%).There were zero cases of hardware failure. All osteotomies healed at final follow-up. Conclusion: This study shows successful radiographic outcome after hallux valgus correction using a tension band construct and allowing immediate full weight-bearing in a surgical shoe in the postoperative period. Significant deformity correction was achieved and maintained and all osteotomies healed. The Re+Line tension band bunion correction system can be safely used as a successful option to fix distal first metatarsal osteotomies, while allowing patients to fully weight bear in a surgical shoe postoperatively and potentially return to activities faster than when using traditional fixation methods. Future studies are needed to assess functional outcomes and patient satisfaction with this novel technique.

Object Widespread use of MR imaging has contributed to the more frequent diagnosis of vestibular schwannomas (VSs). These tumors represent 10% of primary adult intracranial neoplasms, and if they are symptomatic, they usually present with hearing loss and tinnitus. Currently, there are 3 treatment options for quality of life (QOL): wait and scan, microsurgery, and radiosurgery. In this paper, the authors' purpose is to determine which treatment modality yields the highest QOL at 5- and 10-year follow-up, considering the likelihood of recurrence and various complications. Methods The MEDLINE, Embase, and Cochrane online databases were searched for English-language articles published between 1990 and June 2008, containing key words relating to VS. Data were pooled to calculate the prevalence of treatment complications, tumor recurrence, and QOL with various complications. For parameters in which incidence varied with time of follow-up, the authors used meta-regression to determine the mean prevalence rates at a specified length of follow-up. A decision-analytical model was constructed to compare 5- and 10-year outcomes for a patient with a unilateral tumor and partially intact hearing. The 3 treatment options, wait and scan, microsurgery, and radiosurgery, were compared. Results After screening more than 2500 abstracts, the authors ultimately included 113 articles in this analysis. Recurrence, complication rates, and onset of complication varied with the treatment chosen. The relative QOL at the 5-year follow-up was 0.898 of normal for wait and scan, 0.953 for microsurgery, and 0.97 for radiosurgery. These differences are significant (p < 0.0052). Data were too scarce at the 10-year follow-up to calculate significant differences between the microsurgery and radiosurgery strategies. Conclusions At 5 years, patients treated with radiosurgery have an overall better QOL than those treated with either microsurgery or those investigated further with serial imaging. The authors found that the complications associated with wait-and-scan and microsurgery treatment strategies negatively impacted patient lives more than the complications from radiosurgery. One limitation of this study is that the 10-year follow-up data were too limited to analyze, and more studies are needed to determine if the authors' results are still consistent at 10 years.

Osteoporotic Vertebral Fractures

Osteoporotic vertebral fractures usually heal with kyphotic deformities with subsidence of the vertebral body when treated conservatively. Corrective vertebral union using only antiosteoporotic pharmacotherapy without surgical intervention has not been reported previously. An 81-year-old female with osteoporosis presented with symptomatic fresh L1 vertebral fracture with intravertebral cleft. Segmental vertebral kyphosis angle (VKA) at L1 was 20° at diagnosis. Once-weekly teriparatide administration, hospitalized rest, and application of a thoracolumbosacral orthosis alleviated symptoms within 2 months. Corrective union of the affected vertebra was obtained with these treatments. VKA at 2 months after injury was 8° (correction, 12°) and was maintained as of the latest follow-up at 7 months. Teriparatide has potent bone-forming effects and has thus been expected to enhance fracture healing. Based on the clinical experience of this case, teriparatide may have the potential to allow correction of unstable vertebral fractures without surgical intervention.

Abstract Background: While the indications of parathyroid hormone (PTH) in osteoporosis prevention and management have been established, its indications in the treatment of osteoporotic vertebral fractures remain unknown. This study aimed to compare the effects of intervention (percutaneous vertebroplasty followed by anti-resorptive agents) and conservative treatment (PTH administration) in patients with osteoporotic vertebral fractures, as well as to investigate the optimal duration of PTH administration. Methods: A retrospective study was conducted using data of patients treated for osteoporotic vertebral fractures between January 2015 and November 2019. Treatment was selected based on the patient’s age, comorbidities, and patient’s preference after explaining the expected advantages and disadvantages of each treatment. Group C was administered PTH injections once weekly, whereas Group I underwent vertebroplasty followed by the administration of anti-resorptive agents. Radiological and clinical parameters were analyzed between two groups.Results: This study enrolled 58 patients (77 vertebrae). Group C included 24 patients (38 vertebrae) with average age of 77.50 ± 7.19 years (range, 65–85 years), average bone mineral density (BMD) of −3.39 ± 0.86 (range, −2.5 to −5.8), average follow-up period of 27.47 ± 7.60 weeks (range, 12–49 weeks). Group I included 34 patients (39 vertebrae) with an average age of 76.20 ± 8.67 years (range, 65–92 years), average BMD of −3.35 ± 0.91 (range, −2.5 to −5.1), average follow-up period of 30.82 ± 10.95 weeks (range, 16–59 weeks). There was no significant difference between the two groups in initial demographic, clinical and radiographic parameters. Group I showed significantly better clinical and radiological outcome during the last follow-up. Regarding side effects in Group C, two cases of dizziness (8.3%), nausea and vomiting (8.3%) were reported. In Group I, cement leakage was found in 26 vertebrae (66.7%), and cement leakage complications were observed in four patients (11.8%). Conclusion: Conservative treatment using PTH injection demonstrated slower pain relief and lesser suppression of vertebral height loss than vertebroplasty. However, PTH injection demonstrated a lower risk of procedure-related complications. The patient’s age, preference, and general condition with respect to the procedure’s risk should be considered when determining treatment options for osteoporotic vertebral fracture in old age.

Background: The choice of an optimal method for correction of aortic valve stenosis or insufficiency remains the matter of debate. Some clinicians prefer transluminal balloon angioplasty, some would perform an open type commissurotomy, or aortic valve replacement, or to valve leaflets repair with various materials, while others opt for the Ross procedure. Each of these techniques has its advantages and disadvantages both in the early postoperative period and in the long-term.Aim: To assess the results of the Ross procedure, its complications, survival, and probability of reoperations in the long-term.Materials and methods: We retrospectively analyzed the results of 32 Ross procedures performed from the end of 2012 to the beginning of 2019 in children aged from 3 days to 18 years. Eight children were below 1 year of age, including one newborn. A pulmonary autograft was placed into the aortic position in all children. In 31 children, a homograft was placed into the pulmonary artery. In one patient, an aortic autograft was implanted instead of the pulmonary artery valve. The mean patient age was 6.8 years, mean bodyweight 27.7 kg (range, 3.9–74.6 kg).Results: Two patients died in the early postoperative period (mortality 6.25%). We examined 26 patients at the follow-up, with its mean duration of 2.5 years. There were no indications for replacement of the homograft during the follow-up. One patient, in whom we had implanted an aortic autograft into the pulmonary position, required its replacement after 4.5 years. We have no data on death rates in the long-term.Conclusion: The Ross procedure provides satisfactory results in the early and intermediate postoperative period. Continuous follow-up is needed to determine the time points and the proportion of repeated interventions with a pulmonary homograft and aortic valve.
