In order to facilitate the learning of distal radius shortening osteotomy by junior surgeons, the main assumption was that using a three-dimensional procedural simulator was better than a bone procedural simulator. After viewing a video, ten junior surgeons performed a distal radius shortening osteotomy: five with a bone procedural simulator (Group 1) and five with a three-dimensional procedural simulator (Group 2). All subsequently performed the same surgery on fresh cadaveric bones. The duration of the procedure, shortening of the radius, and the level of osteotomy were significantly better in Group 2. The three-dimensional procedural simulator seems to teach distal radius osteotomy better than a bone model and could be useful in teaching and learning bone surgery of the wrist.

Abstract Objective This study aimed to compare the necessary scutum defect for transmeatal visualisation of middle-ear landmarks between an endoscopic and microscopic approach. Method Human cadaveric heads were used. In group 1, middle-ear landmarks were visualised by endoscope (group 1 endoscopic approach) and subsequently by microscope (group 1 microscopic approach following endoscopy). In group 2, landmarks were visualised solely microscopically (group 2 microscopic approach). The amount of resected bone was evaluated via computed tomography scans. Results In the group 1 endoscopic approach, a median of 6.84 mm3 bone was resected. No statistically significant difference (Mann–Whitney U test, p = 0.163, U = 49.000) was found between the group 1 microscopic approach following endoscopy (median 17.84 mm3) and the group 2 microscopic approach (median 20.08 mm3), so these were combined. The difference between the group 1 endoscopic approach and the group 1 microscopic approach following endoscopy plus group 2 microscopic approach (median 18.16 mm3) was statistically significant (Mann–Whitney U test, p < 0.001, U = 18.000). Conclusion This study showed that endoscopic transmeatal visualisation of middle-ear landmarks preserves more of the bony scutum than a microscopic transmeatal approach.

Background: Concomitant distal radius and distal ulna metaphysis or head fractures (DRUF) are uncommon and acceptable results have been reported from cast immobilisation and internal fixation. Methods: We reviewed the charts of 1094 patients treated for distal radius fracture at our institution in a two year period from 2009 to 2010. 24 patients with concomitant DRUF with were treated by cast immobilisation (group 1, n = 11), internal fixation of both bones (group 2, n = 7), internal fixation of radius alone (group 3, n = 2), and internal fixation of radius with distal ulna resection (group 4, n = 4). Patients treated by surgery underwent intraoperative assessment of distal ulna stability to determine the indication for ulna fixation. Post surgical range of motion, clinical parameters, and functional outcome scores (Gartland-Werley and modified Mayo) were measured. Results: Wrist motion was comparable in each group. Radiographic parameters were better in surgical groups. 23 of 24 patients achieved excellent/good outcomes based on Gartland-Werley scores, while 12 of 24 achieved good modified Mayo wrist score. There was a case of distal ulna non-union in group 1, and another case of delayed distal radius union in group 2. Conclusions: By evaluating patients’ functional requirement, and dynamic fluoroscopy examination, satisfactory outcomes can be achieved for various presentations of DRUF.

Background: Flexor tendon rupture is a major complication after volar locking plating for distal radius fracture (DRF). Few studies have investigated changes in the rate of postoperative flexor tendon rupture in patients with DRFs. The present study aimed to investigate the changes in the rate of postoperative flexor tendon rupture and to assess plate placement and reduction positions. Methods: We retrospectively reviewed patients in whom more than 24 months had passed since DRF surgery. The patients were interviewed by telephone. Forty-nine patients (50 fractures; 2007–2009) from institution A were included in group 1 and 81 patients (84 fractures; 2013–2016) from institution B were included in group 2. The DRF surgery method was similar between the two groups. The rate of flexor tendon rupture, Soong classification grade, and radiological index (i.e., volar tilt [VT], radial inclination [RI], and ulnar variance [UV]) were statistically investigated in both groups. Results: Patient epidemiology was not significantly different between the two groups. The flexor tendon rupture rates were 2% and 0% in groups 1 and 2, respectively, without a significant difference. With regard to the Soong grade, 44 fractures were grade 2 and 6 were grade 1 in group 1, whereas 18 were grade 2, 38 were grade 1, and 28 were grade 0 in group 2, with a significant difference (p < 0.05). With regard to the radiological index, the mean VT values were 5° and 11° in groups 1 and 2, respectively, with a significant difference (p < 0.05). However, RI and UV showed no significant difference. Conclusions: Plate placement and reduction positions, which are risk factors for flexor tendon ruptures after DRFs, have improved recently when compared with previous findings. With these changes, the rate of flexor tendon rupture is presumed to have decreased.

ABSTRACT Introduction: The aim of this multi-center retrospective study was to quantify the changes in alveolar bone height and thickness after using two different rapid palatal expansion (RPE) activation protocols, and to determine whether a more rapid rate of expansion is likely to cause more adverse effects, such as alveolar tipping, dental tipping, fenestration and dehiscence of anchorage teeth. Methods: The sample consisted of pre- and post-expansion records from 40 subjects (age 8-15 years) who underwent RPE using a 4-banded Hyrax appliance as part of their orthodontic treatment to correct posterior buccal crossbites. Subjects were divided into two groups according to their RPE activation rates (0.5 mm/day and 0.8 mm/day; n = 20 each group). Three-dimensional images for all included subjects were evaluated using Dolphin Imaging Software 11.7 Premium. Maxillary base width, buccal and palatal cortical bone thickness, alveolar bone height, and root angulation and length were measured. Significance of the changes in the measurements was evaluated using Wilcoxon signed-rank test and comparisons between groups were done using ANOVA. Significance was defined at p ≤ 0.05. Results: RPE activation rates of 0.5 mm per day (Group 1) and 0.8 mm per day (Group 2) caused significant increase in arch width following treatment; however, Group 2 showed greater increases compared to Group 1 (p < 0.01). Buccal alveolar height and width decreased significantly in both groups. Both treatment protocols resulted in significant increases in buccal-lingual angulation of teeth; however, Group 2 showed greater increases compared to Group 1 (p < 0.01). Conclusion: Both activation rates are associated with significant increase in intra-arch widths. However, 0.8 mm/day resulted in greater increases. The 0.8 mm/day activation rate also resulted in more increased dental tipping and decreased buccal alveolar bone thickness over 0.5 mm/day.

The effect of videotaped presentation of a maze, with and without reinforcement during correct “trials,” was investigated to determine whether learning could occur without the correlated response being manifested. Three groups of 10, female albino rats of the Wistar strain, 120 days old, were employed. The stimuli were presented on a monitor during acquisition. Group 1 received the film and reinforcement during correct “trials” and performed significantly better than Group 2, which received the film but no reinforcement and Group 3 which received neither film nor reinforcement on test trials in the actual maze. Empirical and theoretical support were obtained for the notion that learning would occur without responding.

Background: Frenum that encroaches on the margin of the gingiva may interfere with plaque removal and can lead to gingival recession and midline diastema. Thus, to maintain proper oral hygiene and prevent gingival recession, frenectomy is done. Frenectomy can be accomplished by conventional frenectomy technique, which has certain disadvantages. To overcome those drawbacks, paralleling technique of frenectomy has been introduced. Both the techniques can be performed by using various treatment modalities. Aim: The purpose of this clinical study was to compare the bleeding during surgery, post-operative wound healing and patient's perception towards the conventional frenectomy technique with scalpel, paralleling frenectomy technique with scalpel and paralleling technique with electrocautery. Materials and method: A total of 30 subjects with gingival or papillary frenal attachment were selected and equally divided into three groups. Group 1 was treated by conventional technique with scalpel, Group 2 by paralleling technique with scalpel and Group 3 by paralleling technique with electrocautery. Various parameters such as bleeding during surgery, patient's perception towards the various techniques and post-operative wound healing were evaluated. Results: The results showed that bleeding during surgery was minimum in group 3 as compared to other two groups. Patient's perception towards paralleling technique with scalpel, was found better than the other groups. At 7th day, though there was a difference in the healing but at 21st day wound healing was almost similar in all the three groups. Conclusion: Based on our findings and clinical outcome, paralleling technique with scalpel provided better patient's perception and an efficient and satisfactory option for frenectomy.

Background: Footwork training is important in coaching basic movements in badminton. This research aims to learn about the influence of footwork training on improving leg muscles strength. Methods: The study used a randomized pretest-posttest control group design. The participants consisted of 42 male badminton players of Universitas Pendidikan Ganesha, Bali, Indonesia, who split into two groups of footwork training (ten repetitions two sets (group 1) and five repetitions with four sets (group 2)). The coach gave the footwork exercise three times per week for 6 weeks to each group and measured the leg muscle strength using the dynamometer test. Results: The result of the within-group paired T-test before and after the training shows group 1 and group 2 (p<0.05). For group 1, the mean of leg muscle strength was 114.19±33.13 kg before the training and 183.19±33.56 kg after the training, with an increase of 60% (69 kg). On the other hand, for group 2, the mean score of leg muscle strength before the training was 113.05±31.30 kg and after the training was 141.10±34.91, with an increase of 25% (28 kg). The leg muscle strength difference between the groups before and after the training was tested using the independent T-test with a significant α=0.05. Comparing the differences of leg muscle strength for both the groups before the training was p= 0.90, and after the training was p=0.00. Conclusion: The conclusion is training badminton footwork ten repetition two sets better than five repetitions four sets to improve leg muscle strength.

Abstract Background: Parallel osteotomy is essential for favorable osteotomy reduction and healing and technically challenging during diaphyseal ulnar shortening osteotomy (USO). This study aimed to evaluate the advantages of guided osteotomy for parallel osteotomy and reduction osteotomies and healing over freehand osteotomy. It also aimed to identify surgical factors affecting healing after diaphyseal USO.Methods: Between June 2005 and March 2016, 136 wrists that had undergone diaphyseal USO for ulnar impaction syndrome (UIS) were evaluated. The wrists were divided into two groups according to the osteotomy technique (Group 1: freehand osteotomy, 74 wrists; Group 2: guided osteotomy, 62 wrists). The osteotomy reduction gap and time to osteotomy healing (union and consolidation) were compared between the groups. A multiple regression test was performed to identify the surgical factors affecting healing. The cut-off length of the reduction gap to achieve osteotomy union on time and the cut-off period to decide the failure of complete consolidation were statistically calculated. Results: The baseline characteristics were not different between the two groups. The osteotomy reduction gap, time to osteotomy union, and complete consolidation were shorter in Group 2 than in Group 1 (p=0.002, <0.001, 0.002). The osteotomy reduction gap was a critical surgical factor affecting both time to osteotomy union and complete consolidation (p<0.001, <0.001). The use of a dynamic compression plate affected only the time to complete consolidation (p<0.001). The cut-off length of the osteotomy reduction gap to achieve osteotomy union on time was 0.85 mm. The cut-off period to decide the failure of complete consolidation was 23.5 months after osteotomy.Conclusions The minimal osteotomy reduction gap was the most important for timely osteotomy healing in the healthy ulna and a guided osteotomy was beneficial to reducing the osteotomy reduction gap during USO.
