Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. PVNS occurs in two types: localized and diffuse. Localized type is characterized by focal involvement of the synovium with either nodular or pedunculated masses, Diffuse type affects virtually the entire synovium. Diffuse type has reported more recurrence rate. We have experienced a patient who has diffuse type PVNS of ankle joint and report an optimal method of surgical treatment.

목적: 방사선 소견에서 슬개골 골절이 발견되었을 때 치료 방침 결정에 초음파 영상의 임상적 유용성을 알아보고자 하였다. 대상 및 방법: 2006년 3월부터 2009년 9월까지 슬개골 골절로 치료받은 20명 20예를 대상으로 하였으며, 남자가 8예, 여자가 12예였고, 우측이 13예, 좌측이 7예였으며, 평균 연령은 43세(14~72세)였다. 초음파를 이용하여 굴곡-신전시 슬개 지대 파열 여부를 보는 Drayer 검사와 연계하여 치료 방침을 결정 하였다. 횡 골절이 10예, 종 골절이 8예, 분쇄 골절이 2예가 있었으며, 초음파를 이용하여 슬개 지대의 파열 유무와 Drayer 검사가 양성인지 음성인지를 보았다. 결과: 슬개 지대가 파열되지 않은 12예의 경우 전예에서 Drayer 검사는 음성이었으며, 별도의 고정 없이 보행을 허용하여 보존적 치료를 하였다. 슬개 지대가 완전 파열된 4예는 Drayer 검사가 양성이었으므로 관혈적 정복술을 시행하였고, 슬개 지대가 부분적으로 파열되어 Drayer 검사가 음성이었지만, 골절의 전위가 2 mm 이상인 2예는 비관혈적 나사 고정술로 좋은 임상적 결과를 보였다. 결론: 슬개골 골절에서 초음파는 방사선 소견, Drayer 검사와 연계하여 치료 방침을 결정 하는데 유용한 검사 방법 중의 하나로 생각된다. Purpose: The purpose of this study is to evaluate the clinical usefulness of ultrasound in treatment of patella fracture. Material and Methods: Twenty cases of twenty patients with patella fracture radiographically from March, 2006 to September, 2009 were involved in this study, there were 8 males and 12 females, there were 13 right knees, 7 left knees, the average age was 43 years (range, 14~72 years). We decided the methods of treatment by using the ultrasound in conjunction with Drayer's test that examining the intactness of patella retinaculum. There were 10 transverse, 8 vertical and 2 comminuted fractures, we examined the patella retinaculum by using the ultrasound and performed Drayer's test. Results: In 12 cases of intact retinaculum, Drayer's test was negative and we allowed patients ambulation without surgical fixation especially. In 4 cases of completely ruptured retinaculum, Drayer's test was positive and we treated the patella fractures by the use of ORIF (open reduction and internal fixation) method, in 2 cases of partially ruptured retinaculum, Drayer's test was negative but displacement of fractures were more than 2 mm, we treated the patella fractures by the use of CRIF (closed reduction and internal fixation) method and obtained clinically satisfactory results. Conclusion: In conjunction with radiographs and Drayer's test, an ultrasound would be one of the useful diagnostic modality for determining treatment method of the patella fracture.

The purpose of this study is to investigate the efficacy of bone regeneration of combined demineralized bone matrix (DBM) and osteoconductive allogeneic cancellous bone granule implantation in critical size bone defect, rabbit radius model. We grafted the mixture of DBM and allogeneic cancellous bone granules in the experimental group, and the mixture of autoclaved DBM and allogeneic cancellous bone granules in the control group in 30 New Zealand White rabbits. At the 3, 6, 9, and 12 weeks post-implantation, radiographic and bone mineral density BMD evaluation were performed, and micro-CT and histologic assessments were performed with 6 and 12 week specimens. In comparison of the results of radiographic, BMD, and micro-CT evaluations, the experimental group showed much more and earlier bone formation than the control group, which indicated the enhanced bone regeneration by the effect of DBM on allogeneic cancellous bone granule scaffolds. Histologic evaluation also revealed rapid bone resorption, new bone formation, and maturation in experimental groups. There was no inflammatory or foreign body giant cell infiltration suggesting biologic incompatibility. Combined DBM and allogeneic cancellous bone granule composite grafts will be useful alternatives to autogenous bone grafts in various clinical conditions which require bone regeneration.
