세 마리의 소형견이 4단계의 내측 슬개골 탈구로 내원하였다. 세 마리 모두에서 일반적인 기존 수술 방법으로는 슬개골 탈구가 환납되지 않았다. 따라서 슬개골 탈구를 교정하기 위해 대퇴 단축 절골술이 실시되었다. 수술 후에 세 마리 모두 임상 증상이 개선되었고 합병증이나 재발은 확인되지 않았다. 대퇴 단축 절골술은 심한 골격 기형과 관련된 내측 슬개골 탈구가 있는 소형견에서 효과적인 치료 방법으로 고려될 수 있다.

개의 양측성 고관절 이형성을 치료하기 위해 실시하는 슬로컴의 편측 3중 골반 절골술을 개선하기 위해 고안된 변형 3중 골반 절골술의 효과에 대해 알아보고자 본 연구를 실시하였다. 변형 3중 골반 절골술은 양측 장골 절골술과 치골결합 절골술을 동시에 실시하는 방법이다. 변형 3중 골반 절골술을 실시한 36마리와 편측 3중 골반 절골술을 실시한 7마리의 개에 대한 품고, 체중, 수술 시간, 골 유합기간, 복합증 등의 자료를 조사, 기록하였다 임상 증상과 고관절 이형성의 등급, Norberg angle, percentage of femoral head coverage, 골반 직경에 대해 수술 전, 직후, 수술 후 2, 4, 8, 12, 24주에 각각 측정, 기록하였다. 편측 3중 골반 절골술을 실시한 개체의 평균 연령과 체중은 각각 $9.0\pm4.9$개월, $24.8\pm7.5kg$ (n=7)이었다. 수술 후 평균 $3.0\pm1.0$일에 스스로 일어서고 $8.3\pm0.6$일부터는 걸을 수 있었다(n=3). 수술 전과 24주 후의 평균 임상 증상 등급은 각각 $2.2\pm0.42$ (n=6), $3.5\pm0.7$ (n=2)이었다. 평균 수술 시간은 $107.3\pm38.9$분 (n=4)이었다. 변형 3중 골반 절골술을 실시한 개체의 평균 연령과 체중은 각각 $8.7\pm3.0$개월, $26.9\pm7.6kg$ (n=36)이었다. 이중 25마리는 수술 후 평균 $4.9\pm3.7$일부터 스스로 일어날 수 있었고 평균 $7.3\pm4.8$일 후부터 보행이 가능하였다 변형 3중 골반 절골술을 실시한 개체의 수술 전과 24주 후의 평균 임상 증상 등급은 각각 $2.3\pm1.5$ (n=27), $3.2\pm0.7$ (n=9)로 수술 전보다 유의적으로 개선되었다.(P<0.01). 평균 수술 시간은 $143\pm42.8$분(n=24)으로 두 번의 편측 3중 골반 절골술보다 단축되었다 변형 3중 골반 절골술을 실시한 개체의 수술 전 방사선학적 평균 고관절 등급은 양측 모두 $3.2\pm0.9$이었고 수술 직후의 좌 우측 평균 고관절 등급은 각각 $2.7\pml.1,\;2.7\pm0.9$ (n=36) 이었다. 수술 직후와 2, 4, 8, 12, 24주 후의 고관절 등급이 수술 전에 비하여 유의적으로 개선된 것을 확인하였다.(P<0.01). 수술 후 정기적인 검사 시에 측정한 Norberg angle, percentage of femoral head coverage도 수술 전과 비교해 유의성 있게 증가하였다(P<0.01). 변형 3중 골반 절골술 직후의 평균 골반직경은 수술 전의 골반직경보다 유의적으로 증가하였으며(P<0.01)(n=36) 수술 후 평균 9.3L2.7주에 절골선 유합이 종료되었다(n=21). 반면 편측 3중 골반 절골술을 실시한 경우에는 수술 후 골반경이 수술 전과 비교해 증가하지 않았다. 변형 3중 골반 절골술후에 장액종 형성(1마리), 스크류 변위(4마리), 스크류 부러짐(1마리), 편측성 신경마비(1마리) 등의 부작용이 발생하였다. 이상의 결과를 토대로, 변형 3중 골반 절골술은 개의 고관절 이형성의 효과적인 치료 방법이라 사료된다.

Freiberg 병은 비교적 드문 골연골증으로 주로 사춘기 여자의 제2 중족골 두에서 발생한다. 그 치료는 다양하여 관절내 유리체 제거술, 골두 절골술 또는 골두 절제술 등의 수술이 시도되고 있다. 관절경을 이용한 치료는 회복 기간을 단축시키는 동시에 술후 발생하는 강직을 감소시키는 장점이 있다. 저자들은 초기의 Freiberg 병에 대해 중족지 관절경을 이용하여 유리체 제거술 및 변연절제술을 시행하고 그 결과를 보고하고자 한다.

Purpose: The aim of this study was to evaluate the radiographic and clinical results of short scarf osteotomy that has minimized longitudinal cut for moderate hallux valgus. Materials and Methods: Total 12 patients (12 feet) were reviewed by medical records and radiographs. All patients were female and the mean age at the time of operation was 41.5 years. The mean followup time was 21.2 months. We modified original scarf osteotomy by shortening the longitudinal cut to 15~20 mm in length. Additionally, Akin osteotomy of the first proximal phalanx was done in 7 feet and Weil osteotomy of the second metatarsal was done in 4 feet. First-second intermetatarsal and hallux valgus angles were analyzed radiographically before and after the operation. And the clinical result was assessed by AOFAS (American Orthopaedic Foot and Ankle Society) hallux score. Results: First-second intermetatarsal and hallux valgus angles were reduced from the mean preoperative values of $14.6^{\circ}$ and $32.8^{\circ}$ to $6.5^{\circ}$ and $11.2^{\circ}$, respectively. The mean AOFAS hallux score was increased from 52.4 points preoperatively to 88.2 points at followup. Three complications were found: metatarsal fracture during the operation, painful scar around second metatarsal head after Weil osteotomy and postoperative neuralgia. There was no transfer metatarsalgia or recurrence of hallux valgus during followup. Conclusion: Short scarf osteotomy would be an effective surgical procedure for moderate hallux valgus with the benefits of minimized soft tissue dissection and stable fixation.

Purpose: This study compared the radiographic and clinical outcomes of simultaneous bilateral short scarf osteotomy with those of unilateral short scarf osteotomy in hallux valgus patients. Materials and Methods: The authors undertook a retrospective chart and radiographic review between January 2015 and June 2017 to identify 15 patients (30 cases, group A) who underwent a simultaneous bilateral short scarf osteotomy. The patients were matched with 30 patients (30 cases, group B) with a unilateral short scarf osteotomy. No significant preoperative differences were observed between the two groups in terms of age, gender, American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, and radiographic parameters. The clinical and radiographic follow-up was carried out at three months and one year. Results: Hallux valgus angles in groups A and B were reduced from the mean preoperative values of 32.5° and 34.7° to 12.5° and 12.2° at 12 months, respectively. The first-second intermetatarsal angles in groups A and B were also reduced from the mean preoperative values of 14.2° and 16.5° to 7.4° and 7.3° at 12 months, respectively. No significant inter-group differences in radiographic outcomes were observed. After three months, the patients in group A reported significantly worse mean pain and functional scores than group B. The mean AOFAS hallux score was higher in group B at the three-month follow-up, but this difference disappeared at the one-year followup. Conclusion: Simultaneous bilateral surgery can be offered to patients with a hallux valgus deformity requiring correction. On the other hand, they should be informed of the long recovery period.

Purpose: This study sought to evaluate the clinical effectiveness of the shortening effect of the modified Weil osteotomy for the treatment of Freiberg's disease. Materials and Methods: We reviewed 21 cases treated with the modified Weil osteotomy for Freiberg's disease from November 2005 to June 2019. The average follow-up period was 32.5 months and the mean age of the patients was 38.3 years. The clinical results were analyzed using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the visual analogue scale (VAS), and the range of motion (ROM) of the metatarsophalangeal joint. In the radiologic evaluation, the length of preoperative and postoperative metatarsal shortening was compared. Results: The average AOFAS lesser metatarsophalangeal-interphalangeal scale showed an improvement from 60.5 preoperatively to 90.9 at the latest follow-up. VAS showed a decrease from 5.4 preoperatively to 0.9 at the latest follow-up. ROM of the affected metatarsophalangeal joint increased from 40.2 degrees preoperatively to 58.6 degrees at the latest follow-up. The mean length of metatarsal shortening was 6.7 mm. There was no transfer metatarsalgia, osteonecrosis, and definite joint space narrowing. Conclusion: Modified Weil osteotomy with second layer cutting is an effective treatment option to restore the joint surface and painless joint motion for patients with Freiberg's disease.

Purpose: To evaluate the effect of shortening scarf osteotomy on pain relief and range of motion (ROM) of the first metatarsophalangeal joint in hallux rigidus patients. Materials and Methods: Twenty-three cases of 19 patients who had been treated with shortening scarf osteotomy for the hallux rigidus between January 2007 and December 2013 were reviewed. The mean follow-up period was 21.4 months, and the mean age was 59.2 years. The first metatarsal bone was shortened until the ROM of the first metatarsophalangeal joint was greater than $80^{\circ}$ or $40^{\circ}$ of dorsiflexion. The length shortened by scarf osteotomy was measured. The authors also measured and compared the joint interval difference of the standing foot using an anteroposterior radiography. Moreover, the difference of ROM of the first metatarsophalangeal joint between the preoperative and final follow-up periods was also compared. The clinical results were evaluated and compared using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and visual analogue scale (VAS) score. Results: The mean shortening length was about 6.5 mm (range, 4~9 mm). The joint space has been increased to 1.8 mm, and the ROM of the first metatarsophalangeal joint has also been increased to $18.4^{\circ}$ after the operation. In three cases, the postoperative ROM has been decreased to less $10^{\circ}$. The AOFAS score has been improved from 41.7 (range, 32~55) to 86.2 (range, 65~95), and the VAS score was also decreased from 3.7 (range, 3~5) to 1.3 (range, 0~3). Two cases have shown no decrease in pain even after the operation. Conclusion: Shortening scarf osteotomy was found to decrease joint pain by decompressing the pressure of the first metatarsophalangeal joint. This osteotomy also helped improve the ROM of the first metatarsophalangeal joint. Shortening scarf osteotomy can be considered one of the effective methods for joint preservation.
