In this paper, we designed 3D-printed orthopedic splint models for patient-specific external coaptation on fracture healing and analyzed the stability of the models through finite element method (FEM) analysis under compressive load conditions. Polylactic acid (PLA) and acrylonitrile-butadiene-styrene (ABS) based 3D splint models of the thicknesses 1, 3, 5 and 7 mm were designed, and Peak von Mises stress (PVMS) and maximum displacement (MD) of the models were analyzed by FEM under compressive loads of 50, 100, 150, and 200 N. The FEM results indicated that PVMS and MD values, regardless of material, had a negative correlation with the thickness of the models and a positive correlation with the compressive load. There was a risk of splint deformation under conditions more extreme than 100 N with 5 mm thickness. For successful clinical application of 3D-printed orthopedic splints in veterinary medicine, it is recommended that the splint should be produced not less than 5 mm thickness. Also, it is expected to be stable when the splint is applied to situations with a compressive load of 100 N or less. There is an advantage of overcoming the limitations of the existing bandage method through 3D-printing technology as well as verifying the stability through 3D modeling before application. Such 3D printing technology will be widely used in veterinary medicine and various fields as well as orthopedics.

Purpose: Ingrown toenails are a common disease in the adolescent period and the treatments could be more conservative for this early stage of the disease. This study is a case series on the results of a gutter splint for an adolescent ingrown toe nail as a simple, comfortable treatment method. Materials and Methods: From 2011 to 2018, 22 patients (mean age, 12.2 years; range, 8~15 years) with ingrown toenails were treated with a gutter splint. There were 16 boys and 6 girls with 7 patients on both great toes, and additional 4 both corners of a nail, giving a total of 33 splints. Flat, plastic straws and glue or suture were used to protect the nail corners under local anesthesia. The medical records were reviewed retrospectively and phone calls were made to obtain the long-term results. Results: Fifteen splints were fixed with a suture and the other 18 splints were fixed with glue. There were 9 cases of recurrence out of 33 gutter splints, 8 out of 15 sutured splints and 1 out of 18 glued splints (p=0.010). There was no gender (p=0.383) or age (p=0.305) difference in the number of recurrences. Conclusion: For growing people, ingrown nails can be cured easily by conservative treatment for a transiently shortened or broken toenail. The glued gutter splint had a reasonable success rate as a first line treatment.

We treated 5 elbows with post-traumatic flexion contractures (mean contracture: 51 degrees) by arthroscopic anterior capsular release and post-operative alternative flexion and extension splint. Each elbow had been resistant to at least six months of conservative therapy. An incongruent ulno-humeral articulation was considered to be a contraindication to this procedure. All patients complained of the residual deformity and some functional deficit. All patients, after failure of non-operative therapy, desired a operative treatment. At follow-up(mean 21.8 months), there was a mean post-operative contracture of 19 degrees, which is within a functional range of motion. So we conclude that arthroscopic capsular release in selected patients is reasonable alternative to open release.

Suppose that dental occlusion is related to body posture. We want to find out that improving occlusal balance may affect vibration and distribution of C.O.P. in which way, by measuring change of posture and center of gravity (center of pressure, C.O.P.) which plays important role in measuring balance sensation. Total 11 students at Kyung Hee dental college students, 4 females and 9 males (age: 23-30) participated in this test, who have normal occlusion (Angle's classification I), no TMJ problems. All of the participants have no tooth loss except 3rd molar, no prosthesis over single tooth restoration, no orthopedic problems which affect balance sensation, and no otorhinolaryngological problems. First, we registrated bite by centric relation, and then fabricated stabilization splint that is increased 3.5mm vertical dimension around premolar region. By F-scan (Tekscan Inc., Boston, Mass), we measured discrepancy of average contact pressure of left and right foot. And we also measured discrepancy of vibration of C.O.P(center of pressure). before setting stabilization splint and after wearing stabilization splint at intervals of 1 week, 2 weeks, 3 weeks after. In normal human beings, improved occlusal balance by stabilization splint leads to decrease of vibration of C.O.P. (P<0.05). One week after wearing stabilization splint, vibration of C.O.P. decreased reliably (P<0.05), two weeks after wearing stabilization splint, vibration of C.O.P. decreased similarly comparing to before wearing and one week after wearing. (P<0.05) After two weeks and three weeks, however, it was hard to find reliability. (P>0.05) Difference between average contact pressure of right and left foot also decreased. (P<0.05) We could find decrease after one week of wearing stabilization splint (P<0.05) and two weeks after, the decrease was more reliable than one week after. (P<0.05) After two weeks and three weeks, however, it was hard to find reliability. Improvement of occlusal balance leads to decrease of vibration of C.O.P. and decrease of difference between right and left average contact pressure.

Purpose: To evaluate the result of the early exercise and rehabilitation after limited posterior operative treatment of the calcaneal fractures. Materials and Methods: Between May 2005 and December 2007, 43 cases with intraarticular calcaneal fractures were treated by open reduction with K-wires and Steinmann pins. Mean age and mean follow-up period were 42.5 years old and 15 months. All patients were treated with the same postoperative protocol, the early exercise of subtalar joint without short leg splint and cast was began after postoperative 1 day, non-weight bearing crutch ambulation did after 2 weeks, partial-weight bearing crutch ambulation did after 6 weeks, without crutch ambulation did after 10 weeks. The fractures was classified by Essex-Lopresti and Sanders classification using radiographs and the functional outcomes were evaluated by circle draw exercise, AOFAS score. Results: By Essex-Lopresti classification, the tongue type was 6 cases (14%), the joint depression type was 15 cases (35%), the combined type was 22 cases (51%). By Sanders classification, type II were 10 cases (23%), type III were 15 cases (58%), and type IV were 8 cases (19%). By AOFAS functional evaluation, the mean preoperative scores were 70.3 and 70.5 respectively, mean postoperative scores were 83.7 and 86.9 respectively. There were satisfactory results in 40 cases but 3 cases were unsatisfactory including on case of lateral impingement and 2 cases of traumatic arthritis of subtalar joint. Conclusion: We obtained satisfactory result of the early exercise of subtalar joint without short leg splint and cast and rehabilitation after limited posterior operative treatment of the calcaneal fractures.

Purpose: To evaluate the effectiveness of ankle arthrography in diagnosis and treatment of the ankle sprain. Materials and Methods: Arthrography was performed to eighteen patients who were diagnosed as ankle sprain clinically from September, 1990 to April, 2003. Splint immobilization for three days and return to daily life were for the eleven patients who showed normal limits of extension of joint and no dye leakage on arthrography, cast for 3 weeks and compression brace wearing were for 4 patients who showed anterior talofibular ligament tear on arthrography. 3 patients diagnosed as anterior talofibular and calcaneofibular ligament tears were treated with cast for 6 weeks and then brace for 3 weeks. Results: The range of motion of the injured joint was recovered normally at the time of 3 month of postoperative follow up examination. But two patients complained a mild pain after exercise but it did not affect ordinary activities. Eleven patients who were normal on arthrography returned to daily activities in a week. Conclusion: It is reasonable to determine the extent of ankle sprain and treatment method for it using arthrography.
