This study was performed to report the signalment, history, and outcome of modified retinacular imbrication technique (MRIT) for treatment of cranial cruciate ligament rupture (CCLR) in dogs. Nine dogs (12 stifles) presented with chronic hindlimb lameness associated with CCLR. They were 7 males and 2 females. Six were Yorkshire terriers. Mean age was 8 years (range,2 to 14 years), and mean weight was 5.6kg (range, $1.8{\sim}19kg$). Three dogs had bilateral CCLR and six dogs had unilateral CCLR (2 left stifles and 4 right stifles). Nine stifles (8 dogs) had concomitant patellar medial luxation. Surgery was performed in eight stifles (5 dogs) and recovery rate of 100%. Three stifles (2 dogs) were underwent simultaneously femoral trochleoplasty. Mean time to the normal gait after surgery was 30 days. There were not postoperative complications.

The purpose of this study was to report the reliability and validity of oblique single-cut rotation osteotomy (OSCRO) in 3D-reconstructed canine bone models with femoral varus and torsional deformities. A healthy adult male beagle was recruited to create a 3D bone model, and this bone model was modified by using a 3D program. Fifteen bone models were constructed for this study. OSCRO simulation was performed in accordance with the plan after printing using a 3D printing machine. The anatomical lateral distal femoral angle (aLDFA), anteversion angle (AA), anatomical caudo-distal femoral angle (aCdDFA), mechanical caudo-distal femoral angle (mCdDFA) and pre- and postoperative bone length were calculated. There were no significant differences between the target values and postoperative values. In addition, the difference between pre- and postoperative bone length was small (p = 0.001). Our findings suggest that OSCRO could be an effective surgical option for MPL with bone deformities in small-breed dogs that often undergo conventional distal femoral osteotomy.

Two small-breed dogs and two cats, with an average body weight of 4.88 kg (range: 4.3-5.5 kg), suffered hindlimb lameness due to luxation with or without fractures of the tarsocrural joint. These patients underwent tarsocrural arthrodesis with epoxy putty external skeletal fixator. The animals' skins were incised minimally, and the articular cartilage of the tarsocrural joint was removed, followed by autogenous cancellous bone grafting. Epoxy putty and positive Centerface®, pins with diameters 1.2 mm and 2.0 mm, were used for connecting bar and as a full pin fixation, respectively. All the patients regained the ability to bear weight on the affected limb within 3-7 days and resumed a normal gait within 9-15 weeks. The external skeletal fixator frame was removed within 13-17 weeks without major complications. Tarsocrural arthrodesis using epoxy putty external skeletal fixator resulted in excellent outcomes without severe postoperative complications in this study. Epoxy putty external skeletal fixator can be a valuable surgical option for tarsocrural arthrodesis in patients weighing less than 5.5 kg.

Importance: Canine extraction of large carnivores can pose significant risk due to extensive tissue damage during aggressive bone reduction. This report highlights a rare instance in which the use of a piezoelectric surgical unit (PSU) for maxillary canine extraction in a large carnivore resulted in successful outcomes with minimal tissue damage. Case presentation: A 10-year-old male African lion presented with decreased appetite because of bilateral maxillary canine fractures. Intraoral radiographs revealed enlarged root canals and periapical radiolucency of the fractured canines, leading to a diagnosis of periapical periodontitis and pulpitis. To extract the right maxillary canine, conventional method using hand instrument failed to achieve adequate luxation, necessitating the use of the flat blade of the PSU to sever the periodontal ligament. The left maxillary canine was extracted using PSU from the beginning, and the extraction time was markedly shortened by using PSU without additional alveolar bone damage or bleeding. Conclusion and Relevance: This case demonstrated that utilizing PSU for canine extraction in a lion resulted in periodontal ligament separation, reducing damage to the alveolar bone and shortening surgical time. It suggests the promising application of PSU in tooth extraction for large wild animals, indicating its potential significance in veterinary dentistry.

A 3-year-old, 26 kg, castrated male Chow Chow was presented for assessment of weight-bearing lameness of the left hind limb. The patient had a history of triple pelvic osteotomy on the left side to correct hip dysplasia 2 years prior to his presentation of clinical signs and underwent total hip replacement on the right coxofemoral joint 1 year later. Upon physical examination, pain and crepitus were noted on the left hip joint during extension. Radiological examination revealed coxofemoral joint subluxation and moderate degenerative bone changes on the left hip joint and pelvic axis, which relates to acetabular angles that were changed after triple pelvic osteotomy (TPO). Preoperative computed tomography was used for 3-dimensional printing to establish an accurate surgical plan. The changed angles of the acetabulum after TPO were evaluated, and rehearsal surgery was performed using a 3-demensional printing bone model. Three months after the THR surgery, the function of the affected limb had improved, with no lameness. Complications, such as luxation and implant failure, were not observed until 6 months after the operation. Accurate evaluation of acetabulum angles and rehearsal surgery using a 3D-printed bone model is effective for total hip replacement after unsuccessful TPO.

유치열에서 가장 외상이 호발하는 부위는 상악 유중절치이며, 영구치열에서 치관부 파절이 많이 나타나는 것과는 달리, 정출, 함입, 측방 변위, 탈구 등 지지조직에 한정된 손상이 많이 나타난다. 그러나, 유구치는 외상에 의해 손상을 받는 경우가 매우 드물게 보고되고 있으며, 단일 치아 또는 다수 치아의 파절이 주를 이루고 있다. 즉, 탈구 또는 변위되는 경우가 매우 드물고 이러한 경우의 치료에 대한 보고도 거의 없다. 본 증례는 4세 5개월 된 여아에서 외상으로 인해 하악 좌측 유측절치의 정출, 유견치의 탈구와 함께 제1유구치의 설측 변위가 발생하였는데, 계승 영구치의 맹출 시기와 환아의 협조도를 고려하여 가철성 장치를 이용한 하악 제1유구치의 재위치를 시도하여 양호한 결과를 얻었기에, 유구치의 외상으로 인한 변위 시 치료 방법의 선택에 도움이 되고자 보고하는 바이다.

치은연 하방에 치아 우식증이나 치아 파절이 발생했을 때, 치아를 탈구시켜 즉시 정출시키는 외과적 정출술을 이용한 치관 연장술은 자연치를 보존하고 추가적인 치주적 수술 없이 단기간에 심미적인 보철 치료를 가능하게 한다. 본 환자는 16세 남환으로 본원 보존과로부터 상악 좌측 중절치의 심미 수복을 위해 본원 보철과로 의뢰되었다. 상악 좌측 중절치는 근관치료가 되어 있었으며 치관-치근 파절로 인해 협측 치관 길이는 4mm였으며 구개측 판막을 열었을 때 근심 구개측 치경부 파절 범위는 치은 하방 3-4mm에 위치하였다. 외과적 정출술을 통한 치관연장술을 시행하였으며 경과 관찰 및 임시 치아의 단계를 거쳐 3개월 후에 전부 도재관으로 수복하여 만족할 만한 임상결과를 얻을 수 있었다.

치아에 외상을 받은 경우 치수 생활력의 상실은 흔한 일이다. 치수 생활력을 검사하는 방법으로는 임상적, 방사선학적으로 여러 가지가 있지만, 미성숙 외상치의 경우 일시적 현상과 가성 반응이 나타날 수 있으므로 치수 괴사에 대한 정확한 진단은 매우 어렵다. 생활력을 상실한 치아는 염증성 치근흡수, 치근단 낭종 등의 발생을 방지하기 위하여 치수 치료를 시행한다. 그러나 미성숙 영구치의 경우, 치수 치료를 시행 후 치근 성장이 정지될 수 있어 결과적으로 얇고 짧은 치근이 형성되어 장기적인 예후는 좋지 않다. 본 임상 증례에서는 외상으로 인하여 실활된 초기 영구치에서 치근단부의 최소한의 침습적 치근단 형성술로 계속된 치근 형성을 보여 이에 보고하는 바이다.

Two dogs with hindlimb paralysis were referred to the Teaching Animal Hospital of Chonbuk National University. We performed an acupuncture in two cases. Case No.1 was a 5-year-old, 3kg intact mixed breed female dog presented with hindlimb paralysis during last 3 days. Physical examinations, CBC, serum chemistry, urinalysis and radiography carried out. The diagnosis was the thoracolumbar disk disease of Tl2-Tl3 on the basis of above these tests. Acupoints selected were Lumbosacral point, GV-5(Xuan Shu), GV-20(Bai Hui), GB-30(Huan Tiao), GB-31(Feng Shi), ST-36(Zu San Li) and GB-34(Yang Ling Quan). we performed an acupuncture therapy five times at 2 days intervals for 15 minutes each time. Case No.2 was 7-year-old, 6.0kg, mixed breed male dog which was presented with the history of hindlimb paralysis since 2 months. The medical history of the patient revealed that the condition did not respond to medicinal therapy. The diagnosis was the thoracolumbar disk disease of Tl3-Ll and left patellar luxation (one or two grade). We decided to perform acupuncture in this case also and the Lumbosacral point, GV-5(Xuan Shu), GV­6(Ji Zhong), GV-7(Zhong She), GB-30(Huan Tiao), GB-31(Feng Shi), ST-36(Zu San Li), GB-34(Yang Ling Quan) were used. We performed acupuncture therapy at day 3, 6, 8 and 10 for 15 minutes each time. The response to an acupuncture therapy in two patients was good and the patients were almost recovered from hindlimb paralysis.

복부 팽만과 간헐적인 가벼운 좌측후지의 파행을 나타낸 11년령의 암컷 말티즈견이 내원하였다. 신체검사에서 복부 촉신 시 동통을 호소하였고 농성의 질 삼출물을 나타내었다. 혈액화학적 검사결과 독성변화를 동반한 심한 백혈구감소증, 질소혈증, 고인산혈증, 그리고 저나트륨혈증이 관찰되었다. 복부 방사선검사에서 소장을 앞쪽과 등쪽으로 변위시키는 연부조직음영의 관상구조를 가진 매스가 관찰되었고 복부 초음파검사에서 에코성의 물질이 함유된 종괴는 자궁음영으로 판단되어 자궁축농증으로 진단하였다. 후지의 방사선검사결과 양쪽 무릎에서 내측 슬개골탈구와 외측 종자뼈가 4-5 조각으로 분화된 다분화를 관찰하였다. 환자는 곧바로 난소자궁적출술을 받아 잘 회복되었으며 정상적인 혈액화학 수치를 보였다. 좌측 후지의 파행은 간헐적이고 매우 경미하였으므로 특별한 처치를 하지 않았다. 이후 지금까지 3개월동안 뚜렷한 후지파행은 관찰되지 않았다. 여러조각으로 갈라진 후지의 양측성 외측종자뼈는 선천적인 종자골 다분화로 여겨지며 파행과 직접적인 관련성은 없는 것으로 판단된다.
