  • With the increase in number of the athletic population and elderly demographic, the demand for orthopedic splints, which are used to support a damaged body, has rapidly increased. Current splints mainly consist of inner and outer parts, which are multiple fabrics covered with polyurethane and nonwoven fabrics, respectively. However, the laminated materials with directly applied pre-polymer coating lead to a high defect rate because of the uneven thickness on the surface. Thus, this study proposes an indirect coating method using a precise clearance controller, which enables the even application of the coating material on multiple inner parts while maintaining a constant thickness. In addition, a roll-to-roll (R2R) technique is applied instead of the sewing mechanism to bond the inner and outer materials together and enhance the productivity in the final stage. In the advanced methods, there is a storage tank that contains polyurethane, a clearance controller, and pairs of rollers in the upper and lower rows. To improve the quality of the products and optimize the equipment, three controllable factors are determined: the viscosity of polyurethane, angle of the gap controller and number of pairs of rollers in the R2R system.

  • The simple and easy treatment with cast or splint has been applied to stabilize long bone fractures in farm animals. Applying cast or splint is relatively easier than surgical fixation and may temporarily stabilize fracture site. However, the internal fixation provides strong stabilization and early recovery of limb function. In this report, we describe six cases of limb fractures in calves repaired by internal fixation. Fracture sites are various and affected ages are between 1 day and several months old. In some cases, patients were treated with cast or splint before admitting to Veterinary Medical Center. In these patients, regardless of initial treatment fractures were not immobilized. Consequently we decided to treat these patients with open reduction and internal fixation. The fracture repair with implants(bone plate, screw, cerclage wire, and intramedullary pin) were effective and satisfactory in calves which had been failed by application of cast. Although the cost of orthopedic treatment in farm animal is one of the most important considerations from the practical point of view, internal fixation has many benefits in newborn and young calves. And simplicity of postoperative management is also practically significant benefit expected from infernal fixation In conclusion, we suggest that internal fixation will produce better result than external coaptation in calve.

  • Plantar fasciitis is the most common cause of heel pain. The diagnosis of plantar fasciitis is primarily based on the presentation of symptoms and physical examination. Patients usually complain of heel pain at the medial calcaneal tubercle when taking their first step in the morning or when walking after resting. Diagnostic imaging is rarely required for the initial diagnosis of plantar fasciitis; however, it can be used for differential diagnosis. Conservative treatments, such as stretching, rest, ice massage, oral analgesics, foot orthotics, use of night splint, and corticosteroid injection, may be effective. The majority of patients report improvement with conservative treatments, and those who show no response from conservative treatments for a duration of six months or longer can consider extracorporeal shock wave therapy or surgery.

  • Long face patients are characterized by excessive anterior facial height, lip incompetence at rest, anterior open bite, and gummy smile. A major problem is an inferior rotation of the posterior maxilla and upper molars. Long face patients have been the most difficult for orthodontist to treat successfully. In growing patients, the methods for impeding excessive vertical growth have been used high pull head gear, functional appliance, and combined type of two. One significant improvement comes from using a full arch splint to deliver force to the maxilla more vertically. In adult patients, orthodontic camouflage treatment is biomechanically difficult and doesn't work when the problem is primarilly vertical. Surgical maxillary impaction provides a means for successfully treating most of problems. Also, superior reposition of the chin via a mandibular inferior border osteotomy is effective in decrease of lower anterior facial height and correction of the poor chin-lip balance. Post-surgical stability and the physiologic response are good. The coordinated orthodontic and surgical treatment is necessary for solution the difficult skeletal deformity.

  • Purpose: The purpose of this study is to assess the result of conservative treatment in displaced radial head fracture. Materials and Methods: We analyzed 15 cases of displaced radial head fracture who were treated conservatively from April 1992 to May 2002. Follow-up period was more than 1 year. They were all males and the average age of patients was 20.2($11{\sim}24$) years. The average follow-up period was 13.4($12{\sim}15$) months. They were able to do active pronation and supination more than 70 degrees initially, who were applied long arm splint less than 1 week. The functional rating index modified after B.F. Morrey and no further displacement and union state of fragment in simple X-ray were used in follow-up assessment. Results: On the basis of the functional rating index modified after B.F. Morrey that included elements of pain, motion, strength, and stability, the results were 8 excellent, 7 good in patients who were treated conservatively, who had union and no further displacement of fragment in follow-up. Conclusion: We conclude that if they are able to do active pronation and supination more than 70 degrees initially, we take them to do early range of motion exercise after subsiding swelling, which can restrict limitation of range of motion exercise and return to the living early.

  • This article review the animals physical therapy. It is so called veterinary physical therapy. The animals physical therapist is working to physical therapy for animals in veterinary clinical field. The veterinary medicine has not veterinary rehabilitation medicine or physical therapy for animals, also physical therapy field in Korea. So, This research will explain about animals physical therapy of Korea and other countries' by journals and internet information and suggest the future of the animals physical therapist. Finally, The veterinary physical therapy is not used to veterinary clinical field in now. But, The veterinary physical therapy will desire to the view of medical serve and economy by the host of animals and clinical veterinarian the future. Animal physical therapy is a new and rapidly developing field of health care for animals. The benefits of physical therapy have long been recognized in humans. More recently, work in the veterinary field has shown the same benefits of physical therapy to be true for animal patients. Performing orthopaedic or neurological surgery, or fitting a human patient with a cast or splint, and then discharging the patient is an outdated approach. In such cases, physical therapy is clearly warranted. Similarly, recent research has shown that post-surgical rehabilitation and therapy after injuries significantly improves the functional outcomes for animals. Physical Therapy is a healthcare profession directed at evaluating, restoring and maintaining physical function and movement. Working with the owner, veterinarian and often other healthcare professionals, a physiotherapist helps your animal to achieve and maintain optimal health and well-being. Equipped with a specialized university Bacheloriate education and intensively educated in Anatomy, Physiology, Biomechanics, Histology, Neurology, and Pathology, PT's are able to assess, diagnose and treat movement and function. Physical Therapy, Sports Medicine and Rehabilitation are recognized sciences applied to both humans and animals. The goals of physiotherapy are to relieve pain, restore range of motion/movement, improve function, prevent injuries and expand the physical potential of the patient. Once in the field, physical therapists actively continue their education to keep up to date on the latest treatments and technologies. Via continuing education courses, physiotherapists can learn how to apply their unique and specialized knowledge to other animal species.

  • Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

  • The revision of the Korea Organ Transplantation Act (KOTA) in 2018 included hand/arm among the organs that can be transplanted. The first hand transplantation since the revision of KOTA took place in January 2021. A 62-year-old male patient experienced hand amputation on July 13, 2018, by a catapult injury. The patient first visited our institute 3 months after the injury. After serial interviews and an overall evaluation, the patient was registered on the hand transplantation waiting list in January 2020. On January 9, 2021, the patient underwent hand transplantation at the right distal forearm level. The total operation time was 17 hours 15 minutes, and the cold ischemic time was 4 hours 9 minutes. Postoperative immunosuppression was administered based on the protocol used for kidney transplantation. Two acute rejection episodes occurred, on postoperative days 33 and 41. Both rejection episodes were reversible with rescue therapy of a higher tacrolimus trough level, steroid pulse therapy, and topical immunosuppressants. Controlled passive range of motion exercise was started on postoperative day 10. Dynamic splint was applied on postoperative day 18. At 1 year, graft maintenance and functional improvement were satisfactory, and the patient showed a Disabilities of Arm, Shoulder and Hand score of 25.8. We successfully performed the first hand transplantation surgery under the KOTA amendment. It came from the organic and effective cooperation of plastic, orthopaedic, and transplantation departments and we believe it will guarantee the future ongoing success.

  • Osteoarthritis (OA) of the temporomandibular joint (TMJ) is a severe form of temporomandibular disorders (TMDs), presenting gradual breakdown of articular cartilage and subchondral bone by the functional load sustained to exceed the physiologic tolerance of the joint. In such a joint loaded, offensive bioactive materials such as matrix degrading proteins, cytokines, and free radicals increase in concentration to shift the tissue response in the joint to degeneration from regeneration or remodeling. Recently, it has been issued that obesity can play an offensive role in pathogenesis of OA in a metabolic way. Adipokines released by adipose cells are present at higher concentration in the arthritic joint and joints of obese individuals. However, because of conflicting data reported, further scientific study should be performed to elucidate the practical role of adipokines in pathogenesis of TMJ OA. As far as the clinical signs and symptoms of TMJ OA are not much different from those of other forms of TMD and any definitive treatment modality to control directly the bone resorptive activity is not available yet, the treatment of TMJ OA should be directed to reduce the physical load and enhance the physiologic tolerance of the joint by means of conservative treatment such as physical therapy, medication, and occlusal splint therapy for sufficient period and, if needed after that, supplementary surgical procedure such as intra-articular injection, arthrocenthesis, and arthroscopic surgery that have turned out to be effective to control OA signs and symtpoms. Enthusiastic reassurance and motivation for patients to control behaviors for themselves to reduce unnecessary functional load in daily life is very important for the joint to reach to more favorable orthopedic stability of the TMJ more quickly, guaranteeing more successful management TMJ OA.
