Closed Intramedullary Nailing

Background: The tibia, or shinbone, is the common fracture long bone in body. There are two option includes, reamed and unreamed of surgical treatment of fractures. Reamed nail has some advantage but they significantly harmful the endosteal circulation. Unreamed nail surplus the endosteal circulation but provide a less stable fixation. Afterward, because of ability to lock the nail proximally and distally, closed intramedullary nailing turned into an acknowledged treatment for closed shaft cracks during the ninth decade. Aim: The main objective is to treat the tibia fractures by implanting the Intramedullary nailing system (Interlocking cannulated tibia nail and Expert tibia nail) manufactured by Auxein Medical Private Limited, Sonipat, India. Material and Methods: In this retrospective study, studied the results of intramedullary tibia nail in treatment of tibia fracture. A total of 25 consecutive patients were included in this study (11male, 14 female and average age 42.9 years). Fracture type was classified as per the Muller AO classification of fracture. Results: The outcomes of clinical treatment were obtained in our study; No pain (92%), Mild pain (8%) after 2 year follow up. The follow up of patients were taken on 4-week, 1-year, 2-year according to VAS score. Paired t test was performed for statistical data analysis using Minitab and values of p<.05 were taken to indicate significant value with confidence interval of 95%. No implant related problem have been found like loosening, bending, corrosion etc. Conclusion: Our outcomes with interlocking cannulated and Expert tibial interlocking nailing are empowering and exhibit the advantages of new nailing framework. It has been concluded that intramedullary tibia nailing system is best method for treatment of tibia fracture with good results and outcomes.

Acceptability Criteria

Twenty-two patients underwent surgery for 23 complex articular fractures of the distal radius of C.3 type, according to the AO classification. The surgical treatment consisted, in all cases, of a closed, or limited-open, reduction and external fixation. The functional and radiographic results were analysed at a mean follow-up of 40 months. This retrospective study confirms that satisfactory functional results where obtained in 12 out of the 15 wrists where all the intra and extra-articular parameters of the Fernandez’ criteria where respected. For those wrists where keeping with Fernandez’ criteria for intra-articular parameters and ulnar variance was not possible, four of eight had satisfactory results. As far as the acceptability criteria for radial inclination and dorsal tilt are concerned, the functional results seem to suggest that a little wider tolerance than proposed in the literature could be accepted.

The aim of this article is to summarize recent bioinformatic and statistical developments applicable to NMR-based metabolomics. Extracting relevant information from large multivariate datasets by statistical data analysis strategies may be of considerable complexity. Typical tasks comprise for example classification of specimens, identification of differentially produced metabolites, and estimation of fold changes. In this context it is of prime importance to minimize contributions from unwanted biases and experimental variance prior to these analyses. This is the goal of data normalization. Therefore, special emphasize is given to different data normalization strategies. In the first part, we will discuss the requirements and the pros and cons for a variety of commonly applied strategies. In the second part, we will concentrate on possible solutions in case that the requirements for the standard strategies are not fulfilled. In the last part, very recent developments will be discussed that allow reliable estimation of metabolic signatures for sample classification without prior data normalization. In this contribution special emphasis will be given to techniques that have worked well in our hands.

In this review, we summarize established and recent bioinformatic and statistical methods for the analysis of NMR-based metabolomics. Data analysis of NMR metabolic fingerprints exhibits several challenges, including unwanted biases, high dimensionality, and typically low sample numbers. Common analysis tasks comprise the identification of differential metabolites and the classification of specimens. However, analysis results strongly depend on the preprocessing of the data, and there is no consensus yet on how to remove unwanted biases and experimental variance prior to statistical analysis. Here, we first review established and new preprocessing protocols and illustrate their pros and cons, including different data normalizations and transformations. Second, we give a brief overview of state-of-the-art statistical analysis in NMR-based metabolomics. Finally, we discuss a recent development in statistical data analysis, where data normalization becomes obsolete. This method, called zero-sum regression, builds metabolite signatures whose estimation as well as predictions are independent of prior normalization.

ABSTRACTObjectives: The use of osseointegrated implants as an endoestal anchorage device to provide support for dental prostheses is a reliable and widely accepted treatment modality. The purpose of this study was to evaluate the clinical performance of non-submerged implants placed in the maxilla or in the mandible.Methods: A total of 146 International Team for Implantology (ITI) (Straumann AG, Waldenburg, Switzerland) implants were placed in 42 patients (20 women, 22 men, mean age 42). The cases were examined retrospectively in order to evaluate the clinical efficiency of non-submerged ITI implants and to determine the success rate of implant retained/supported prosthesis after a 5-year period. All implants were assessed clinically and radiographically on a yearly basis.Results: The 5-year cumulative success rates for maxillary and mandibular implants were 91.00% and 97.81%, respectively. The most common prosthetic complication was abutment accompanied by screw loosing (3.42%). Veneering material fracture was documented in only one patient.Conclusions: Within the limitations of the observation period and sample number, the present findings confirmed sufficient success and survival rates of ITI implants placed in mandible as well as implants placed in the maxilla after a 5-year period.

OBJECTIVE: to evaluate Crohn's disease recurrence and its possible predictors in patients undergoing surgical treatment. METHODS: We conducted a retrospective study with Crohn's disease (CD) patients undergoing surgical treatment between January 1992 and January 2012, and regularly monitored at the Bowel Clinic of the Hospital das Clínicas of the UFMG. RESULTS: we evaluated 125 patients, 50.4% female, with a mean age of 46.12 years, the majority (63.2%) diagnosed between 17 and 40 years of age. The ileum was involved in 58.4%, whereas stenotic behavior was observed in 44.8%, and penetrating, in 45.6%. We observed perianal disease in 26.4% of cases. The follow-up average was 152.40 months. Surgical relapse occurred in 29.6%, with a median time of 68 months from the first operation. CONCLUSION: The ileocolic location, penetrating behavior and perianal involvement (L3B3p) were associated with increased risk of surgical recurrence.

Abstract Purpose：This retrospective study summarized the clinical, radiographic and arthroscopic manifestation of synovial chondromatosis (SC) of the hip, along with the post-operative effect to discuss the curative effect of arthroscopic management of hip SC.Methods: 21 patients underwent arthroscopic surgery from the same surgeon for hip SC were followed up for an average of 45 months. T-shaped capsulotomy was routinely performed in each case. Visual analog scale, range of motion, modified Harris Hip score and International Hip Outcome Tool score were collected preoperatively and at the time of the latest follow-up. All patients’ demographics, radiographs and arthroscopic images were collected to summarize and conclude the similarities and differences of their manifestation.Results: Large wedged-clumps of loose bodies demonstrated distinguishable radiographic, arthroscopic appearance and demanded different surgical strategy. Postoperative scores were all significantly improved. One case of residual pain and two cases of residual loose bodies with no symptom related were reported at the final follow up. All but one patients were satisfied with the outcome. Conclusion: Arthroscopy treatment of hip SC with T-shaped capsulotomy has demonstrated good result in terms of clinical outcome score, recurrence rate and complication rate. On the basis of this study, we concluded the clinical performance of large wedged-clumps of loose bodies of hip SC.
