Posterior Ankle Arthroscopy

Background: Osteochondral lesions of the talus are frequent pathologies of the ankle joint. Especially through arthroscopy, the treatment is kept as minimally invasive as possible. However, there are some drawbacks as to the reachability because of the high congruency of the ankle joint. Here, either noninvasive distraction or maximal dorsiflexion may be an option for better access to the lesion. The purpose of this study was to evaluate maximal dorsiflexion compared to neutral position or noninvasive distraction of the ankle joint in the arthroscopic reachability of the talar dome. The hypothesis of this study was that maximal dorsiflexion would allow for greater accessibility of the talar dome compared to neutral position or noninvasive distraction of the joint. Methods: Twenty matched pairs (n=40) of anatomical ankle specimens were used. The effects of neutral position, maximal dorsiflexion, and noninvasive distraction of the ankle joint on arthroscopic accessibility of the ankle joint were tested. After disarticulation of the talus, reach was measured and compared between the 3 positions. Results: In neutral position, 13.7±1.2 mm of the talar dome was reached laterally and 14.0±1.0 mm medially. In maximal dorsiflexion, the distance was 19.0±1.1mm laterally and 19.8±1.4 mm medially, and in noninvasive distraction it was 16.1±1.5 mm laterally and 15.7±1.0 mm medially. The statistical comparison showed a significantly better reach in dorsiflexion laterally ( P = .003) and medially ( P = .026). Conclusion: Accessibility of the talar dome in maximal dorsiflexion was superior to that in neutral position or noninvasive distraction. Clinical Relevance: Results of this study may allow for better planning in arthroscopic treatment of osteochondral lesions of the talus.

Clinical Correlations

Medical curricula are continually evolving and increasing clinical relevance. Gross anatomy educators have tested innovations to improve the clinical potency of anatomic dissection and found that clinical correlations are an effective method to accomplish this goal. Recently, surgical educators defined a role for laparoscopy in teaching anatomy. We aimed to expand this role by using surgical educators to create clinical correlates between gross anatomy and clinical surgery. We held supplements to traditional anatomy open dissection for medical students, including viewing prerecorded operative footage and live laparoscopic dissection performed on cadavers. The main outcome measures were assessed through pre- and postsession surveys. Greater than 75 per cent of students found the demonstrations highly valuable, and students perceived a significant increase in their understanding of abdominopelvic anatomy ( P < 0.01). Additionally, 62 per cent of students with previous interest in surgery and 10 per cent of students without previous interest in surgery reported increased interest in pursuing surgical careers. Our demonstrations advance the use of minimally invasive surgical technology to teach gross anatomy. Live laparoscopic demonstrations augment traditional anatomic instruction by reinforcing the clinical relevance of abdominopelvic anatomy. Additionally, laparoscopic demonstrations generate interest in surgery that would otherwise be absent in the preclinical years.

Latar Belakang. Resin komposit merupakan bahan pilihan untuk reparasi Gigi Tiruan Cekat porcelain fused to metal (PFM) Karena estetis baik dan manipulasi mudah. Tujuan penelitian ini adalah mengetahui perbedaan kekuatan geser perlekatan resin komposit pada permukaan logam Gigi Tiruan Cekat dengan menggunakan resin komposit jenis packable dan jenis flowable. Metode penelitian. Subjek penelitian berupa logam NiCr (Noritake, Japan) berbentuk silinder dengan diameter 10 mm dan tinggi 3 mm. Penelitian dibagi menjadi dua kelompok, masing-masing terdiri dari 10 subjek. Kelompok pertama reparasi dengan resin komposit packable (Z250™ 3M ESPE, USA) dan kelompok kedua reparasi dengan resin komposit flowable (Dyad flow, Kerr, USA). Permukaan subjek dikasari dengan wheel diamond bur, dietsa dengan asam fosfat 37 % (Scotchbond™, 3M ESPE, USA) kemudian dicuci dan dikeringkan, selanjutnya diaplikasikan silan (Rely X™ Ceramic Primer, 3M ESPE, USA) dan bonding (Adper™ Single Bond, 3M ESPE, USA). Permukaan kemudian dilapisi dengan resin komposit packable dan flowable, disinari selama 40 detik. Subjek penelitian direndam di dalam distilled water dan dimasukkan ke dalam incubator dengan suhu 37°C selama 7 hari. Uji kekuatan geser dilakukan dengan menggunakan Universal Testing Machine. Data dianalisis dengan uji t. hasil uji t menunjukkan terdapat perbedaan bermakna kekuatan geser reparasi gigi tiruan cekat pada permukaan logam (p<0,05). Kesimpulan penelitian ini adalah kekuatan geser reparasi pada permukaan logam dengan menggunakan resin komposit flowable yang mengandung bahan coupling agent lebih tinggi dibandingkan reparasi pada permukaan porselen dengan menggunakan resin komposit packable. Background. One of selected material by repairing the fixed partial denture was composite resin because of its good aesthetics and low manipulation. The aim. This research was aimed at identifying the differences of shear bond strength of composite resin on metal surface by using different composite resins, namely packable and flowable composite resins. Method. The research subjects were cylinders with 10 mm in diameter and 3 mm in height. The research subjects with metal material of NiCr (Noritke, Japan) involved two groups. The first group comprising 10 repair subjects with composite packable (Z250™, 3M ESPE, USA) and 10 repair subjects with flowable composite (Dyad flow, Kerr, USA). The surface of the subjects were roughned with wheel diamond bur and etched with 37% phosphate acid (Scotbond™, 3M ESPE, USA) were applied. The surface was then coated with packable and flowable composite resins and light-cured for 40 seconds. The research subjects were immersed in distilled water and put into the incubator at temperature of 37°C for 7 days. The shear bond strength test was conducted using the Universal Testing Machine. Data were analyzed using t-test. The result. The research result showed that there were differences of shear bond strength of repair between packable and flowable composite resins. The result of t-test indicated significant diffrences on metal surface (p<0,05). The conclusion of this research is that shear bond strength of repair with flowable composite which contain coupling agent has higher shear bond strength than that of packable composite resin.

Relevance. The use of light-cure sealants and flowable composites for fissure sealing in children is difficult due to the complexity of the procedure. The research aimed to study the efficiency of self-etching self-adhesive flowable composite for fissure sealing in primary molars in children.Materials and methods. The Local Ethical Committee permission and written informed voluntary consents from the parents were obtained before the study. Non-invasive fissure sealing with self-etching self-adhesive flowable composite (Constic, DMG, Germany) was performed in 48 primary molars in 48 children aged 2-5 years (mean 41.2 ± 1.3 months). After 6, 12, 18 and 24 months, the sealant’s retention (%) and frequency (%) of occlusal caries development, and 95% confidence intervals (CI) were calculated. The significance of the difference was assessed by the Student’s t-test.Results. After 6 and 12 months, complete sealant’s retention was revealed in 75.0% (CI 61.2-85.1%) and 60.4% (CI 46.3-73.0%) molars, p > 0.05; it decreased to 27.1% (CI 16.6-41.0%) and 18.7% (CI 10.2-31.9%), p > 0.05, after 18 and 24 months. Complete loss of the sealant was noted in 8.3-18.7% cases. The first caries lesion (2.1%, CI 0.4-10.9%) on the surface with the lost sealant was revealed after 12 months, after 24 months – 4.2% (CI 1.1-14.0%).Conclusions. In primary molars after non-invasive fissure sealing with self-etching self-adhesive flowable composite, complete loss of the sealant was from 8.3% to 18.7% after 6-24 months post-op, partial loss was from 8.3% to 31.3%. Occlusal caries was revealed in 6.3% cases after the sealant loss.
