The lateral hoof of right hind limb of a pregnant Masai giraffe was accidentally injured, and its coronet, hoof wall, and sole were detached in a mass. The bleeding was observed from the exposed dermis of the affected foot for several hours, with second scoreof supporting lameness. The bleeding from the digital artery at the exposed dermis was stopped by epinephrine spray and direct pressing. Nitrofurazone ointment was topocally applied for 5 days and sxytetracycline solusion was delivered by a fluid jet in the affected hoof one month. The calf was born 5 months after the avulsion. The horn of the hoof wall was grown from the coronet to sole, and was gradually filled from the heel to the toe. The growth rate and filling rate of the hoof wall were 0.32mm and 0.54mm a day, respectively.

The calcaneal insufficiency avulsion fracture usually occurs in an area of fused apophysis in adults without significant history of trauma or overuse activities. It is an uncommon injury which has been described in patients with complicated diabetes, Charcot neuroarthropathy, amyloidosis with neuropathy, severe osteoporosis, and other conditions. Discussion of the issue of fracture location is still not sufficient. We report on a case of a 50-year-old male who experienced a non-traumatic diabetic calcaneal insufficiency fracture. Intraoperatively, a biopsy specimen was obtained from the exposed fracture site for histological study. We assume that the calcaneal fused apophyseal line is the weak point of failure due to various incomplete mixtures of trabecular bone, woven bone, and cartilaginous tissues, and may fail when repeated tensile stress is imposed.

교련부 분리는 대동맥판막 탈출증에 의한 대동맥판 역류를 일으키는 매우 드문 질환이다. 판막엽의 손상 없이 교련부 분리(avulsion of commissure)에 의해 발생한 중증 대동맥판 역류 2예를 치험하여 보고하고자 한다. 첫 번째 증례에서 교련부 분리에 의한 중증 대동맥판 역류에 대해 5-0 polypropylene으로 연속 봉합하여 교련부 재부착을 통한 성형술을 시행하였다. 수술 소견에서 판막엽은 정상 이었으나 우관상동맥판과 무관상동맥판 사이의 교련부 분리에 의한 중증 역류가 관찰되었다. 수술 후 특별한 문제 없이 회복하던 환자는 대동맥판 역류의 재발이 관찰되어, 술 후 14일째에 재수술을 시행하였고, 재부착을 시행했던 교련부위가 완전히 재분리 되어 있어, 판막 치환술을 시행하였다. 두 번째 증례도 우관상동맥판과 무관상동맥판 사이의 교련부 분리가 관찰되었으며 판막엽은 정상소견이었다. Pledget으로 보강한 5-0 polypropylene을 이용한 다수의 수평매트리스봉합으로 교련부 재부착을 시도하였으나 판막의 교합이 완벽하지 않아 조직판막으로 치환술을 시행하였다.

The neuropathic pain caused by lumbosacral plexopathy as a sequela to extensive pelvic and sacral fractures is rare because many posttraumatic cases remain undiagnosed as a result of the high mortality associated with these types of injury and because of the survivors of multiple trauma, including pelvic fractures, frequently have an incomplete work-up. Although surgical treatments for medically refractory lumbosacral plexus avulsion pain have been reported, an effective surgical technique for pain relief in lumbosacral plexopathy has not been well documented. We describe the effectiveness of spinal cord stimulation [SCS] in a patient suffering from severe neuropathic pain caused by lumbosacral plexopathy after an extensive pelvic fracture.

This study describes the clinical steps taken in the treatment of a patient who had an avulsed right upper central incisor that presented with incomplete root development and chronic apical periodontitis. A 7-year-old boy was referred from a private dentist to a dental office specializing in endodontics. The tooth had remained in a dry environment for 20 minutes, and tooth replantation was performed at an emergency appointment. After clinical and radiographic examinations, root canal decontamination was performed, followed by several changes in intracanal calcium hydroxide medication. Blood clot formation was attempted, but bleeding within the root canal was insufficient; therefore, we opted for an intracanal medication change to stimulate mineralized tissue formation in the apical region. Root obturation was performed 45 days after the last change of intracanal medication, and clinical, radiographic, and tomographic follow-up examinations were performed at 3, 6, 18, and 40 months after the endodontic intervention. The increase in thickness and length of the root structure and the absence of root resorption were verified through follow-up examinations. Therefore, it was concluded that the procedures used were successful for tooth replantation.

구강악안면 영역의 외상은 치아파절, 탈구, 골절, 연조직 손상을 일으킬 수 있으며, 뇌진탕의 원인이 되기도 한다. 미국과 일본에서는 contact sports 일부에서 마우스가드의 장착이 의무화되어 있으나, 현재 한국에서는 운동 시 마우스가드의 장착을 거의 볼 수 없는 실정이다. 마우스가드는 크게 ready-made type과 custom-made type으로 나눌 수 있다. Ready made type의 마우스가드에는 형태가 일정하고 조정이 곤란한 stock mouthguard와 다소 조정이 가능한 mouth formed mouthguard가 있다. Custommade type의 마우스가드는 적합성이 뛰어나며 정확한 교합, 하악위를 재현할 수 있다는 장점이 있다. 마우스가드는 입술과 구강연조직을 치아로부터 보호하고, 치아에 가해지는 충격을 분산시켜 파절이나 탈구가능성을 줄여준다. 또한, 악골의 골절과 변위를 방지하고 충격을 흡수한다. 성장기 아동의 경우 치아손상의 30% 정도가 스포츠나 레포츠에 의한 것이라는 보고가 있으며, 이 경우 치아나 잇몸은 물론 성장 중인 치조골에 악영향을 주게 된다. 이 때 외상처치는 어려우며, 그 예후 또한 불명확하다. 따라서 성장기 아동의 마우스가드 장착은 외상 예방차원에서 중요하다. 이에 저자는 단국대학교 치과병원에 내원한 환아에게 ERKODENT$^{(R)}$사의 ERKOFORM-RVE를 이용한 흡입성형 마우스가드(vacuum type mouthguard)를 적용한 임상경험을 보고하는 바이다.
