Our findings suggest that that administration of 1,000 mg of ascorbic acid together with 400 IU of alpha-tocopherol could be useful in preventing or aiding in the treatment of age-related osteoporosis.
Background Anatomic total shoulder arthroplasty with a nonspherical humeral head and inlay glenoid replacement has been introduced in the past; however, clinical evidence remains limited. We hypothesized that patients with advanced glenohumeral arthritis demonstrate significant improvements in pain and function. Methods Prospective patient-reported outcomes (PROs) included the American Shoulder and Elbow Surgeons score, a pain visual analog scale, and satisfaction. Range of motion was compared to the preoperative status. A sensitivity analysis examined responder rates and compared them to literature thresholds using the minimal clinically important difference and substantial clinical benefit. The preoperative glenoid morphology was determined using the Walsh classification. Zone-specific periprosthetic radiolucent lines were quantified at the last follow-up. Results Thirty-nine shoulders in 36 patients (3 bilateral) with a mean age of 65.9 years (26 males, 13 females) and a mean follow-up of 41.0 months were included. Ninety-three percent had grade III osteoarthritis, and 7% grade II. The glenoid Walsh classification included A1 (25%), A2 (25%), B1 (22%), B2 (25%), and C (3%). All PROs improved significantly ( P < .001) with a mean American Shoulder and Elbow Surgeons score from 30.4 to 77.1, a pain visual analog scale from 8.1 to 1.5, and excellent (9.1/10) patient satisfaction. PRO-related responder rates for minimal clinically important difference and substantial clinical benefit were ≥85%. Forward elevation improved from 107° to 155°, and external rotation from 22° to 51°. One intraoperative glenoid rim fracture led to advanced radiolucency; no other clinically relevant lucency was observed. Conclusion Treatment with inlay total shoulder arthroplasty demonstrated significant functional improvement, excellent pain relief, and patient satisfaction in patients with advanced shoulder arthritis and various glenoid morphology types. Our initial results provide further support for this new option in primary shoulder replacement.
Background: learning basic surgical procedures in medical school, involves acquisition of certain bloody skills. Therefore, to teach this kind of procedure on the patient is becoming more difficult nowadays. An educational alternative is proposed to teach basics surgical skills in undergraduate students in Medical School. Methods: during entire 2002, two theoretical-practical courses on Basic Surgical Maneuvers were developed in the Medicine School of UNNE. These courses were assigned to the 5 th and 6 th year's students. Used models included meet piece, bovine's bowel, heart and lungs, chick's wings; additionally live anesthetized swine and cadavers. All the students had to practice different procedures leaded by an instructor. Before performing these procedures theoretical explanation was supplied in the classroom. Attend to al least 80% of all given class, and to pass a practical final test were the only conditions to pass these courses. All the students had to fill up a survey to assess the perfomance of these courses. Results: the quota of 50 students by each course was completely covered. All the students (100%) passed successfully the courses. The survey reflected this experience as excellent (96%) or very good (4%) in teaching basic surgical procedures. Conclusion: the training in Biologic Models has shown as an excellent strategy to undergraduate surgical education. Key word: teaching-basic surgical maneuvers-bilogical models "The teaching of basic surgical skills in the biologic simulators. Undergraduate educational experience."
Background: Surgical management of unstable distal clavicle fractures (DCFs) remains controversial. Traditional open techniques result in acceptable union rates but are fraught with complications. In response to these limitations, arthroscopic techniques have been developed; however, clinical outcome data are limited. Purpose: The primary purpose was to systematically evaluate the clinical and radiographic outcomes of arthroscopic fixation of unstable DCFs. The secondary purpose was to characterize the overall complication rate, focusing on major complications and subsequent reoperations. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included a search of the PubMed, Web of Science, Cochrane Register of Controlled Trials, EMBASE, and Scopus databases. English-language studies between 2008 and 2019 that reported on outcomes of patients with DCFs who underwent operative fixation using an arthroscopic or arthroscopically assisted surgical technique were included. Data consisted of patient characteristics, fracture type, surgical technique, concomitant injuries, union rates, functional outcomes, and complications. Results: A total of 15 studies consisting of 226 DCFs treated using an arthroscopically based technique were included in the systematic review. The majority of fractures were classified as Neer type II. Most (97%) of the fractures underwent arthroscopic fixation using a cortical button coracoclavicular stabilization surgical technique. Bony union was reported in 94.1% of the fractures. Good to excellent outcomes were recorded in most patients at the final follow-up. The Constant-Murley score was the most widely used functional outcome score; the pooled mean Constant score was 93.06 (95% CI, 91.48-94.64). Complications were reported in 14 of the 15 studies, and the overall complication rate was 27.4%. However, only 12% of these were considered major complications, and only 6% required a reoperation for hardware-related complications. Conclusion: Arthroscopic fixation of DCFs resulted in good functional outcomes with union rates comparable to those of traditional open techniques. While the overall complication profile was similar to that of other described techniques, there was a much lower incidence of major complications, including hardware-related complications and reoperations.
