The aim of this case series is to introduce the One-Time Cortical Lamina Technique, a simplification of the F.I.R.S.T. (Fibrinogen-Induced Regeneration Sealing Technique) in cases where only horizontal augmentation is needed. The indications for this technique are ASA2 and ASA1 anxious patients. Pre-requisites for this surgical technique are: a good amount of keratinized tissue, sufficient alveolar ridge width for placement of implants, thickness of vestibular bone at CBCT planning less than 1 mm with risk of threads exposure. Five patients with horizontal deficiencies were selected to test the efficacy of this approach. The defects were augmented using a porcine cortical bone lamina in combination with collagenated porcine bone mixed with fibrin sealant. The cortical lamina was placed only buccal to the implants and stabilized with fibrin sealant, without pins or screws. Upon completion of the implant surgery, healing abutments were connected to the implants and the soft tissue sutured around them. The healing was uneventful in all cases. Six months after surgery impressions for final restorations were taken and screwed crowns delivered. The new volume had hard consistency and the follow-up CBCT measured an average of 4.17 mm of horizontal bone augmentation. One to three years of follow up demonstrated the maintenance of vestibular volume, hard consistency and clinical stability. Intraoral X-rays showed no marginal bone loss. An advantage of this technique could be the one stage surgery that creates a stable environment for regeneration from day one.

Objectives: Repeated abutment disconnection/reconnection may compromise the mucosal barrier and result in crestal bone level changes. The clinical significance of this phenomenon is not yet clear, as most studies on this topic are short-term. Therefore, the aim of the present study was to evaluate the influence of abutment disconnections and reconnections on peri-implant marginal bone loss over a medium-term follow-up period. Material and methods: Twenty-one patients (6 men and 15 women) with a mean age 66.23 ± 9.35 year at the time of implant placement were included. All patients who received two adjacent nonsubmerged implants were randomly assigned into one of the two groups: definitive multiunit abutments (DEFs) connected to the implant that were not removed (test group) or healing abutments (HEAs) placed at surgery, which were disconnected and reconnected 3–5 times during the prosthetic phase (control group). Peri-implant marginal bone levels (MBL) were measured through periapical X-rays images acquired immediately after the surgery (baseline), at 4–7 months immediately after prosthetic delivery, and at 1-year and 3-year follow-up visits. Results: No implant was lost or presented bone loss of more than 1.9 mm during the 3-year follow-up; thus, the survival and success rate was 100%. Peri-implant mucositis was noticed in 38.1% DEFs and 41.9% of HEAs at the 3-year follow-up assessment. At the end of 3 years, the MBL was −0.35 ± 0.69 mm for participants in the DEFs group and −0.57 ± 0.80 mm for the HEAs group, with significant statistical difference between groups. Conclusions: Immediate connection of the multiunit abutments reduced bone loss in comparison with 3–5 disconnections noted in the healing abutments 3 years after prosthetic delivery. However, the difference between the groups was minimal; thus, the clinical relevance of those results is doubtful.

The objective was to investigate clinical and radiological outcomes of rehabilitations with root-analogue implants (RAIs). Patients restored with RAIs, supporting single crowns or fixed dental prostheses, were recruited for follow-up examinations. Besides clinical and esthetical evaluations, X-rays were taken and compared with the records. Patients were asked to evaluate the treatment using Visual Analogue Scales (VAS). For statistical analyses, mixed linear models were used. A total of 107 RAIs were installed in one dental office. Of these, 31 were available for follow-up examinations. For those remaining, survival has been verified via phone. RAIs were loaded after a mean healing time of 6.6 ± 2.5 months. 12.1 ± 6.9 months after loading, a mean marginal bone loss (MBL) of 1.20 ± 0.73 mm was measured. Progression of MBL significantly decreased after loading (p = 0.013). The mean pink and white esthetic score (PES/WES) was 15.35 ± 2.33 at follow-up. A survival rate of 94.4% was calculated after a mean follow-up of 18.9 ± 2.4 months after surgery. Immediate installation of RAIs does not seem to reduce MBL, as known from the literature regarding screw-type implants, and might not be recommended for daily routine. Nevertheless, they deliver esthetically satisfying results.

Abstract Background Oral implants have helped clinicians to improve the quality of life for many patients. The material of choice for dental implants currently remains titanium type IV, whose mechanical and biological properties have been proven throughout the history of implantology. Yet, this material is not exempt from complications. For these reasons, ceramic alternatives to titanium have emerged. Thus, the purpose of this study is to evaluate peri-implant hard and soft tissue stability with the use of a one-piece ceramic implant (Straumann® PURE Ceramic Implant) during 1 year of follow-up. Study design One-piece all-ceramic zirconia (ZrO2) implants were placed to replace single missing teeth in the esthetic zone. Six to 8 weeks after the procedure, the definitive prosthesis was fabricated. At the time of prosthesis, placement (T0) photographs and periapical radiographs were taken, and the following clinical parameters were recorded: probing depth (PD), plaque index (PI), bleeding on probing (BOP), suppuration on probing (SOP), distance from gingival margin to incisal edge (GM-IE), and Jemt papilla index (JPI). Follow-up appointments were scheduled at 4 (T4), 8 (T8), and 12 (T12) months, when the same parameters were recorded. In addition, plaque control was reinforced and prophylaxis was carried out. In this last appointment, a final periapical radiograph was taken to assess marginal bone loss. Results A total of 32 zirconia implants were placed in 28 patients (16 women and 12 men, aged between 34 and 67 years). The survival and success rate were 96.9%. The increase in probing depth from baseline to 12 months was 0.78 mm. Assessments of plaque index and bleeding on probing showed a slight increase throughout the study. Conclusions The results obtained with the Straumann® PURE Ceramic implants show them to exhibit very good clinical behavior. The survival rate of the implants of our pilot study was 96.9%. For these reasons, we can say that zirconia implants could be an alternative to titanium implants in the esthetic zone.

Abstract Introduction Isolated acute bilateral foot drop due to degenerative spine disease is an extremely rare neurosurgical presentation, whilst the literature is rich with accounts of chronic bilateral foot drop occurring as a sequela of systemic illnesses. We present, to our knowledge, the largest case series of acute bilateral foot drop, with trauma and relevant systemic illness excluded. Methods Data from three different centres had been collected at the time of historic treatment, and records were subsequently reviewed retrospectively, documenting the clinical presentation, radiological level of compression, timing of surgery, and degree of neurological recovery. Results Seven patients are presented. The mean age at presentation was 52.1 years (range 41–66). All patients but one were male. All had a painful radiculopathic presentation. Relevant discopathy was observed from L2/3 to L5/S1, the commonest level being L3/4. Five were treated within 24 h of presentation, and two within 48 h. Three had concomitant cauda equina syndrome; of these, the first two made a full motor recovery, one by 6 weeks follow-up and the second on the same-day post-op evaluation. Overall, five out of seven cases had full resolution of their ankle dorsiflexion pareses. One patient with 1/5 power has not improved. Another with 1/5 weakness improved to normal on the one side and to 3/5 on the other. Conclusion When bilateral foot drop occurs acutely, we encourage the consideration of degenerative spinal disease. Relevant discopathy was observed from L2/3 to L5/S1; aberrant innervation may be at play. Cauda equina syndrome is not necessarily associated with acute bilateral foot drop. The prognosis seems to be pretty good with respect to recovery of the foot drop, especially if partial at presentation and if treated within 48 h.

Preoperative Deformity

Background: Recurrence is relatively common after surgical correction of hallux valgus. Multiple factors are discussed that could have an influence in the loss of correction. The aim of this study was to determine preoperative radiological factors with an influence on loss of correction after distal chevron osteotomy for hallux valgus. Methods: Five hundred twenty-four patients who underwent the correction of a hallux valgus by means of distal chevron osteotomy at our institution between 2002 and 2012 were included. We assessed weightbearing x-rays at 4 time points: preoperatively, postoperatively, and after 6 weeks and 3 months. We investigated the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA), joint congruity, and the position of the sesamoids. Results: At all points of the survey, significant correction of the IMA and HVA was detected. The IMA improved from 12.9 (± 2.8) to 4.5 (± 2.4) degrees and the HVA from 27.5 (± 6.9) to 9.1 (± 5.3) degrees. Loss of correction was found in both HVA and IMA during follow-up with a mean of 4.5 and 1.9 degrees, respectively. Loss of correction showed a linear correlation with preoperative IMA and HVA, and a correlation between preoperative DMAA and sesamoid position. Conclusion: The chevron osteotomy showed significant correction for HVA, IMA, and DMAA. Preoperative deformity, in terms of IMA, HVA, DMAA, and sesamoid position, correlated with the loss of correction and could be assessed preoperatively for HVA and IMA. Loss of correction at 3 months persisted during the follow-up period. Level of Evidence: Level IV, retrospective case series.

Background: The aim of this study is to describe the diagnostic evaluation and treatment in patients with complicated paraesophageal hernia (PEH) and distal gastrointestinal (GI) obstruction. Methods: Three cases with known PEH in the Department of Surgery of the General Hospital of Nea Ionia ‘’Constantopoulion-Patission’’, I woman 78 yrs, II man 88 and III man 78, underwent emergent open surgery for complicated PEH and GI obstruction. Cardiorespiratory distress in all and sepsis in I, were encountered. Case I had coexistent incarcerated abdominal hernia, II had a prepyloric lesion revealed by gastroscopy and III chronic constipation. X-rays and CT scan helped diagnosis. Operative findings: In case I, we found viable incarcerated bowel, gastric fundus and body strangulated in mediastinum, fundus ruptured, and antrum ischemic; total gastrectomy with esophageal and duodenal stapling were performed. In case II, the stomach with an obstructive prepyloric lesion was volvulized in mediastinum; distal gastrectomy, gastrojejunostomy, cruroraphy and fundopexy were performed. In case III, strangulation of the dolichosigmoid was the prominent feature, moreover, incarceration of gastric fundus and transverse colon in PEH sac were also found; reduction of PEH contents, limited resection of thick congenital bands, extended left colectomy, cruroraphy, fundopexy and caecopexy were performed. Results: Case I and II were transferred intubated to ICU. Case I was never stabilized, died after 50 hours; histology confirmed gastric necrosis. Case II was extubated on day 4, discharged on day 28; histology revealed antral ischemia and prepyloric pT2 adenocarcinoma. Case III had uneventful outcome; histology revealed dolichosigmoid ischemia. Follow-up of cases II and III (32 and 30 months respectively) has been uneventful. Conclusion: Obstructive conditions distal to large PEHs may lead to acute complications in hernia contents and emergent surgery is challenging. Obstructive conditions distal to large PEHs may lead to acute complications in hernia contents and emergent surgery is challenging.

Hip Ultrasonography

Ultrasonography of the hip is a new technique which is said to assist in the diagnosis of neonatal hip disorders. The authors were unaware of any reports of formal evaluation of the introduction of this new technology into a District General Hospital. This study outlines several aspects of patient care before and after the introduction of neonatal hip ultrasonography to a Fife hospital as an adjunct to a neonatal orthopaedic clinic. After introduction of ultrasound the proportion of patients where the consultant was ‘very confident’ in the diagnosis increased by 29% (95% confidence intervals 9% to 49%); the proportion of children requiring three or more x-rays in the year following referral fell by 46% (95% confidence intervals 27% to 65%) and the proportion of children requiring five or more follow up attendances in the year following referral fell by 56% (95% confidence intervals 38% to 74%). Introduction of this technology has benefited patients by reducing their need to attend clinics and reducing their overall exposure to ionising radiation. There is a continuing need for ultrasonography to be provided in Fife neonatal orthopaedic outpatient clinics.

Introduction. To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites.Materials and Methods. Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites. All implants were immediately provisionalized with a cement-retained provisional crown. Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3–6 months later. Patients were followed up for 1 year. Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation.Results. One patient was lost to follow-up. At one year, the implant survival and success rate were 98.1%. The mean marginal bone loss after 1 year was −0.17±1.84 mm. Ideal papilla score was recorded at 83.8% of the sites. More than 95.6% of the sites showed no bleeding or inflammation. No procedure-related or device-related adverse events were reported.Conclusion. Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars. Longer follow-up studies are necessary to evaluate the long-term success of these implants.

Neurofibrosarcoma is a malignancy that occurs more frequently in patients with neurofibromatosis- 1 (NF- 1) and rarely may arise independently. This is a presentation of 3 consecutive patients with histologic diagnosis of neurofibrosarcoma who presented to the University of Calabar Teaching Hospital, Calabar from 2011-2013. Two patients presented were associated with NF-1 and were a decade younger than the one without NF-1. Late presentation and poor follow up were notable underlying factors. Long term follow up of patients with NF -1 for early diagnosis and adequate treatment will improve outcome.
