  • Pelvic canal narrowing secondary to pelvic fractures can lead to episodes of recurrent constipation in cats. Triple pelvic osteotomy is considered as a surgical treatment method; however, there is potential for future recurrence of pelvic canal narrowing. This report describes a surgical method using a pelvic symphyseal autograft to keep the distraction of the ischial osteotomy gap to prevent the recurrence of pelvic canal narrowing. A triple pelvic osteotomy was planned to expand the narrow pelvic canal. The cranial ramus of the pubis was cut, and ischiatic and iliac osteotomies were performed. After expanding the ilium, the malunion pelvic symphysis was cut approximately 1 cm and then autografted to the gap of the ischiatic osteotomy line to keep the distraction. The patient showed clinical improvement postoperatively without recurrent pelvic canal narrowing related to triple pelvic osteotomy. However, constipation recurred on post-operative month-5. It was managed conservatively, and subtotal colectomy was performed eventually nine months post-operatively. There were no complications for five months of follow-up.

  • 7살 중성화된 수컷 한국집 고양이가 6개월동안 지속된 변비를 주증으로 본원에 내원하였다. 직장검사에서 골반강의 우측 외측부분의 좁아짐을 보였고, 방사선검사에서는 골반골절의 부정유합으로 인한 골반강의 협착을 확인할 수 있었다. 골반강 직경 비율은 0.68이었다. 직장검사와 방사선검사를 기반으로 골반강 협착으로 인한 변비로 진단하였다. 그래서 골반결합을 절골하여 골반강 확장술을 시행하였고 이를 용이하게 하기 위하여 장골 절골술도 함께 시행하였다. 확장된 골반강을 유지하기 위하여 골반결합 사이에 폴리메칠메타크릴레이트를 성형하여 구조물로 삽입하였다. 절골 한 장골은 뼈판과 나사를 이용하여 다시 고정시켜주었다. 방사선 검사에서 술 후 골반강 직경 비율은 0.91로 증가했음을 알 수 있었다. 술 후 처치로는 항생제, 진통소염제, 락툴로오스경구제 투여와 함께 수액요법을 시행하였다. 환자는 골반강 확장술 후 일주일부터 정상적인 배변을 보였고, 그 이후 6개월동안 재발은 없었다. 이 증례를 바탕으로 골반강 확장술은 골반골절의 부정유합으로 인한 골반강 협착에 따라 발생한 변비에서 유용한 치료법으로 사료된다.

  • 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.

  • Purpose: This study was performed to assess the clinical and radiological outcomes following one-stage hip reconstruction, consisting of open reduction femoral shortening and pelvic osteotomy, for neglected developmental dislocation of the hip (DDH). Materials and Methods: This is a retrospective analysis of 77 hips in 65 patients (46 females and 19 males; 12 had bilateral dislocations), operated at a Ghurki Trust Teaching Hospital in Pakistan between 2013 and 2015. The average age at surgery was $11.02{\pm}3.43$ years. According to the Tonnis classification, there were 10, 14, 22, and 31 patients in grades 1, 2, 3, and 4, respectively. The pelvic procedure utilized in this study was triple osteotomy (47 hips) followed by double and Salter osteotomy (18 and 12 hips, respectively). Postoperative evaluations were conducted using the modified MacKay's scoring system (functional outcomes) and Severin's scoring method (radiological assessment). Results: Postoperatively, there were 38 (49.4%), 19 (24.7%), 14 (18.2%), and 6 (7.8%) hips in Severin grade I, II, III and IV, respectively. According to the modified McKay criteria, there were 22 hips (28.6%) in excellent condition, 44 (57.1%) in good condition, 9 (11.7%) in fair condition and 2 (2.6%) in poor condition. Both patients with poor outcomes had an unstable, painful hip with evidence of avascular necrosis of the femoral head. Conclusion: Based on the results presented here, we recommend the single stage procedure of open reduction, femoral shortening and pelvic osteotomy for treatment of DDH in older children with good to excellent functional and radiological outcomes.

  • Objectives : To review surgical results of post-fusion lumbar flatback treated with pedicle subtraction osteotomy (PSO) or Smith-Petersen osteotomies (SPOs). Methods : Twenty-eight patients underwent osteotomies. Radiological outcomes by sagittal vertical axis (SVA), and pelvic tilt (PT), T1 pelvic angle (T1PA), and pelvic incidence (PI)-lumbar lordosis (LL) at preoperative, postoperative 1 month, and final were evaluated. Oswestry Disability Index (ODI), visual analog scale (VAS) score of back pain/leg pain, and Scoliosis Research Society-22 score (SRS-22r) were analyzed and compared. Patients were divided into 2 groups (SVA ${\leq}5cm$ : normal, SVA >5 cm : positive) at final and compared outcomes. Results : Nineteen patients (68%) had PSO and the other 9 patients had SPOs with anterior lumbar interbody fusions (ALIFs) (Mean age : 65 years, follow-up : 31 months). The PT, PI-LL, SVA, T1PA were significantly improved at 1 month and at final (p<0.01). VAS score, ODI, and SRS-22r were also significantly improved at the final (p<0.01). 23 patients were restored with normal SVA and the rest 5 patients demonstrated to positive SVA. SVA and T1PA at 1 month and SVA, PI-LL, and T1PA at final were significantly different (p<0.05) while the ODI, VAS, and SRS-22r did not differ significantly between the groups (p>0.05). Common reoperations were early 4 proximal junctional failures (14%) and late four rod fractures. Conclusion : Our results demonstrate that PSO and SPOs with ALIFs at the lower lumbar are significantly improves sagittal balance. For maintenance of normal SVA, PI-LL might be made negative value and T1PA might be less than $11^{\circ}$ even though positive SVA group was also significantly improved clinical outcomes.

  • A three-year-old female spayed Lurcher was referred for the treatment of a highly comminuted distal tibial articular fracture. Resection of the area of comminution with a transverse osteotomy of the tibial diaphysis and talar ridges was performed, followed by modified pantarsal arthrodesis and a calcaneotibial screw. The treatment resulted in 7 cm of tibial shortening, equating to a 28% reduction in the total tibial length. Radiographic union of the arthrodesis was successful. Fair use of the pelvic limb was documented long-term. Combined acute limb shortening and modified pantarsal arthrodesis resulted in an acceptable outcome and could be considered in cases of highly comminuted distal tibial fractures.

  • A 7-month-old, 5.2 kg spayed female Norwegian Forest cat was referred for chronic, non-weight-bearing lameness in the left pelvic limb that has been present since 3 months old and has not responded to medical conservative therapy. Based on orthopedic and radiographic examination, concomitant cranial cruciate ligament rupture (CCLR) and medial patellar luxation (MPL) of the left hind limb were diagnosed. In this case, cranial tibial wedge osteotomy (CTWO) was adopted to overcome side effect of performing other osteotomy techniques such as impairing the growth plates in the proximal tibia. Additionally, patient-specific surgical guides were applied to improve surgical accuracy. The patient showed an improvement in weight-bearing scores and gait condition during follow-up periods without complications. In our case, CTWO combined with corrective surgery for MPL can be used to treat concomitant CCLR and MPL without damaged on the growth plates and shows good clinical outcomes in an immature cat. Furthermore, the use of a surgical guide facilitates surgical procedures that minimize surgical error and increase surgical precision. This case study suggests that CTWO assisted by patient-specific surgical guides may be a viable surgical option for treating an immature cat with concomitant CCLR and MPL.
