Fibrous dysplasia is a benign disease that causes replacement of the medullary bone with fibrous tissue in one or more bones. Long bone like femur, tibia and fibular are often affected and occurring under 30 years old. We report a case of two solitary lesions of fibrous dysplasia with pathologic fracture treated with bone curettage, bone graft, plate fixation, who complains of lower leg pain.

Secondary soft tissue injuries can occur from the pressure of the displaced fragment of posterior calcaneal tuberosity in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The soft tissue injury can be prevented by immediate reduction of the displaced fragments. Various techniques can be used to fix the fracture fragments, but the stability of fixation and minimal invasiveness to soft tissue should be considered. This paper reports the successful outcomes of patients with soft tissue compromises in calcaneal tongue-type fractures and calcaneal tuberosity avulsion fractures. The fixation technique of a large cannulated screw and simple cerclage wiring is believed to be a useful surgical option for the treatment of secondary soft tissue compromised calcaneal fractures.

Haglund's syndrome produces retrocalcaneal bursitis or achilles tendinitis due to impingement of posterior superior bursal projection of calcaneus on insertional fibers of achilles tendon. Haglund's syndrome has been mainly associated with wearing rigid counter shoes and with athletes. We experienced three case of late sequelae of secondary Haglund's syndrome after malunion of tongue type calcaneus fracture. It is to be the first description of secondary Haglund's syndrome after calcaneus malunion and also the first report as the late complication of calcaneus fractures. Three cases were all tongue type intraarticular fractures and were treated with $45^{\circ}$ superior angle resection of superior calcaneal tuberosity. Clinical results by modified Rowe score were excellent with complete pain relief for all three cases.

Purpose : The purpose of this study is to investigate an occurrence of valgus deformity of ankle joint after vascularized fibular graft in children. Materials and Methods : Four children under 15 years who were surgically treated with vascularized fibular graft were studied. The age of the patients was from 4 years to 13 years, the follow-up period was from 24 months to 108 months. The causes of vascularized fibular graft were open fracture (1 case), congenital psuedarthrosis (2 cases), hypoplastic ulna (1 case). The tibiofibular synostosis was done in 3 cases and not in 1 case. We measured the tibiotalar angle and bimalleolar angle at immediately postoperative and final radiography, and checked ankle motion, pain, and instability of ankle joint. Results : The A-P mortise angle was not different between initial and final radiography in all cases. The intermalleolar angle increased in all cases at the final radiography. There were no pain, instability and limitation of ankle motion. Conclusion: We consider the tibiofibular synostosis can prevent from ankle valgus deformity after vascularized fibular graft in children.

A 74-year-old female patient, who underwent surgery for a left distal tibiofibular fracture 40 years earlier, visited the hospital with an ankle varus deformity due to malunion. The patient complained of discomfort while walking due to the ankle and hindfoot varus deformity but did not complain of ankle pain. Therefore, correction using supramalleolar osteotomy was planned, and through virtual surgical simulation, it was predicted that a correction angle of 24° and an osteotomy gap open of 12 mm would be necessary. An osteotomy guide and an osteotomy gap block were made using three-dimensional (3D) printing to perform the osteotomy and correct the deformity according to the predicted goal. One year after surgery, it was observed that the ankle varus was corrected according to the surgical simulation, and the patient was able to walk comfortably. Thus, for correction of deformity, virtual surgical simulation and a 3D-printed osteotomy guide can be used to predict the target value for correction. This is useful for increasing the accuracy of correction of the deformity.

Purpose: To evaluate the results of treatments by percutaneous Acutrak screw fixation for intra-articular tongue type fracture of calcaneus, especially in elderly patient or patients with underlying disease including diabetes mellitus. Materials and Methods: Seven cases with intra-articular tongue type fracture of calcaneus, from November 2003 to February 2005, were reviewed. There were 6 males and 1 female with 65 years old mean age (range: $61{\sim}71$ years old). The average follow-up period was 16 months (range: $10{\sim}25$ months). Two Steinmann pins were used for closed reduction. After closed reduction was done like Essex-Lopresti's method, two Acutrak screws were inserted. The third Acutrak screw was inserted at the sustentaculum tali away from sinus tarsi to fix the primary fracture line. The patients were evaluated with Salama scale, the extent of recovery of Bohler angle, state of subtalar joint. Results: Clinical results according Salama scale were excellent in 5 cases, and good in 2 cases. Average preoperative Bohler angle was $13^{\circ}$ (range: $12{\sim}15^{\circ}$). Average postoperative Bohler angle was 31o (range: $23^{\circ}-40^{\circ}$). There were no soft tissue complications. There were two mild subtalar arthritis. Conclusions: We think that percutaneous Acutrak screw fixation is a good option for tongue type fracture of calcaneus in elderly patient or patients with underlying disease including diabetes mellitus.

Purpose: We evaluated the clinical results of operative treatment of the intraarticular calcaneal fracture according to fracture classification. Materials and Methods: There were 25 cases (24 patients) which had at least one year follow up, 17 men and 7 women who were treated from June 1997 to March 2003. We have analysed the Bohler's angle, cruciate angle, width and posttraumatic osteoarthritis in radiological evaluation, and evaluated clinical results according to the Creighton-Nebraska health foundation score. Results: Excellent results were noted in 7 cases, good results in 6 cases, fair results in 4 cases and poor results in 8 cases. Radiological changes showed as follows: Bohler angle $17^{\circ}$, Crucial angle $0.1^{\circ}$, Width 6mm. Conclusion: Type II showed satisfactory results and type IV showed unsatisfactory results in Sanders classification. Proper evaluation of the intraarticular calcaneal fracture by X-ray and CT scan is necessory to predict prognosis and decise method of operative treatment.

The fact that, under similar training activities performed in the same environment, march fractures develop in only a certain percentage of the trainees indicates that intrinsic factors are affecting the prevalence of these fractures. Among these intrinsic factors, the relation between foot arch type and the occurance of march fractures was investigated in this study. From 1997 to 1998, at one infantry medical company of infantry corps in Korea, 15 march fracture patients were detected among infantry soldiers. Quantitative measures of the foot arch (longitudinal) structure of 15(30feet) march fracture patients were established and compared with those of 15(30feet) normal person. The results were as follows. 1. From the lateral X-ray film, three parameters (i.e. calcaneal angle, forefoot angle, height to length ratio)were defined to describe the structure of the longitudinal arch of the foot. 2. The mean value of the calcaneal angle of march fracture group and normal control group showed 16.4 degree, 20.5 degree respectively. The difference between two groups was statistically significant (P>0.006), but those of forefoot angle and height to length ratio were not. 3. In the calcaneal angle twenty-six feet(87%) of march fracture group were lower than 17 degrees but twenty-five feet(83%) of normal control group were more than 17 degrees. That is, march fracture were more prevalent in feet with low calcaneal angle. 4. In the low arch foot, the orthotic device might relieve the energy load carried by the foot, thus reducing the incidence of march fractures, and should be analyzed in further study.

Purpose: Pilon fracture is caused by high energy and axial compression forces, and it is often associated with severe comminution and soft tissue injury. Recently, limited internal fixation of this fracture may avoid the soft tissue complications associated with formal open reduction and internal fixation and avoid incongruity of joint margin associated with conservative treatment. We have treated Ovadia and Beals type II or III pilon fracture with limited internal fixation and the results were satisfactory. Materials and Methods: We analyzed 15 cases of Ovadia and Beals type II or III fractures who were treated by limited internal fixation(K-wire or screw fixation) from January 1995 to December 2000. The average follow up period was 20 months(range, 12 to 38 months). According to the Ovadia and Beals classification, seven cases were type II, and eight cases were type III. Radiographic results were assessed by Ovadia and Beals criteria. We also assessed the functional results by Mast and Teipner criteria. Results: Radiographic results showed good in 67% and fair in 33% of cases. Clinical results showed good in 73% and fair in 27% of cases. There were no complications such as wound infection and skin necrosis, but traumatic arthritis were 2 cases. Conclusion: Pilon fractures are high energy injuries with significantly associated soft tissue damage and traumatic arthritis. Limited internal fixation offers good solution to Ovadia and Beals type II or III fracture.
