Authors report one patient of concurrent fracture of medial malleolus and rupture of deltoid ligament. To the author's knowledge, combined failure of both structures has not been previously reported in Korea. Injury mechanism was classified into pronation -abduction type according to Lauge-Hansen classification. Plain radiograph revealed trimalleolar fracture and posterior ankle dislocation. MRI showed complete rupture of both deep and superficial layer of the deltoid ligament. In conclusion, therefore, concurrent rupture of deltoid ligament should be considered for the surgical treatment in trimalleolar ankle fracture with posterior ankle dislocation resulted from pronation-adduction injury.

Traumatic ruptures of tibialis posterior tendon are much less common and consequently have received little attention. A tibialis posterior tendon rupture associated with a closed medial malleolar fracture occured in a 32 years old man due to slip down. The tendon rupture was not diagnosed before surgery but was recognized at the time of open operation. The treatment was open reduction and internal fixation at the bony fragments with primary repair of the tendon. This tendon injury, although rare, should be considered in the management of ankle fracture because the tendon rupture could easily have been overlooked and failure to recognize this at the time of injury may result in poor long - term ankle function despite a well- healed fracture.

Purpose: Generally, the treatment of ankle trimalleolar open fractures is divided into two stages: external fixation and debridement; and secondary internal fixation. On the other hand, this two-stage operation takes considerable treatment time and is challenging in procedures requiring reduction. The purpose of this study was to evaluate the radiologic and clinical results of an immediate one-stage internal fixation operation considering the wound conditions to overcome two stage operation disadvantages. Materials and Methods: From September 2009 to January 2018, 24 cases of ankle trimalleolar open fractures, who underwent immediate internal fixation and were followed up for at least one year, were studied retrospectively. The open wound was divided into the Gustilo-Anderson classification. Open reduction and internal fixation were performed on every medial and lateral malleolar fracture. On the other hand, with posterior malleolar fractures, surgical or conservative treatment was performed depending on the fragment size. The radiologic outcome was evaluated using the Burwell and Charnley criteria and American Orthopaedic Foot and Ankle Society (AOFAS) scores, and complications, such as infection and posttraumatic arthritis, were used for the clinical evaluation. Results: The wound was classified into eight cases (33.3%) of type I, 11 cases (45.8%) of type II, and five cases (20.8%) of type IIIa. The degree of reduction was anatomical, fair, and poor in 16 cases (66.7%), six cases (25.0%), and two cases (8.3%), respectively. The mean AOFAS score was 79 points, and there were complications, such as infection in three cases (12.5%) and post-traumatic arthritis in two cases (8.3%). Conclusion: Satisfactory results were obtained through immediate surgical treatment in ankle trimalleolar open fractures of types I, II, and IIIa.

The fracture and fracture-dislocation of the neck of the talus (Hawkins' type I-IV) are uncommon injuries and represent only 0.12 to 0.32% of all fracures. Authors clinically evaluated in 12 cases Whom treated fracures of the neck of the talus, at department of orthopaedic surgery, Sun General Hospital, from 1990 to 1996, and the following results are obtained. 1. Of 12 cases, there were 11 males and 1 female, average age was 30 years. 2. Causes of fracture was fall down injury in 7 cases(58%), traffic accident in 4 cases(33%), direct trauma in 1 case(8%). 3. According to the classification by Hawkins' type I in 2 cases(17%), type II in 7cases (58%), type III in 3cases(25%). 4. Associated injuries were calcaneal fracture in 3 cases, fracture-dislocation of talus in 3 cases, subtalar dislocation in 3 cases, medial malleolar fracture in 5 cases, soft tissue injury in 3 cases, femur and tibia fracture in 1 case, and lumbar Spine compression fracture in 1 case. 5. Average time to operation after injury was 2.5 days. 6. In 2 cases were treated conservatively and 10 cases were treated open reduction and internal fixation with screw or K-wire. 7. Complications were avascular necrosis in 4 cases, post traumatic arthritis in 2 cases, skin necrosis in 4 cases, and then ankle fusion was done in 2 cases. 8. High rate of complication was seen in the talar neck fracture associated with calcaneal fracture. In the analysis of above results, evaluated by Hawkins' scoring system were excellent to fair in 75%.

Purpose: The objective of this study was to define the Os submalleolare as an any ossicles below medial malleolus of tibia and to determine the characteristics of clinical and radiological characteristics and to evaluate results of surgical treatment of Os submalleolare in sports player group. Materials and Methods: Twenty-two patients with Os submalleolare were identified between November, 1, 1998 and June, 30, 2002. Results: The mean age was 18.3 years. All patient were male and soccer players comprised 71%(20 cases). Associated disease were 8 cases(29%) of chronic ankle instabilities, one case(4%) of anterior impingement syndrome and one (4%) of plantar fascitis. The most common clinical symptom was pain during walking and sports activity and sign was tenderness around medial malleolus. Only simple radiograph could reveal presence of ossicle and differentiate with acute fracture. If symptom and sign obscured, Bone scan(7 cases) and MRI(3 cases) identify causes of pain and tenderness. As a surgical treatment, all bony fragment caused symptom and sign were eliminated and medial collateral ligament was reattached meticulously. Associated chronic ankle instability were present, modified Brostrom procedure was done simultaneously. On follow-up, The symptomatic pain were wholly disappeared at average 2.2 months (1-6months) after operation. On one year follow-up, all patients have been daily life without any complaints and have gone back to the game within three months. Conclusion: as submalleolare have relatively rare incidence in sports players and most common clinical symptom and sign is tenderness on medial malleolar area of ankle, can be diagnosed both physical examination and plain X-ray film. As a treatment, Removal of ossicle and reattachment of MCL could obtain excellent or good results.

Purpose: We analyzed the ankle bony abnormality of patients with marked ankle instability who had chronic ankle sprain more than 3 years. Materials and Methods: We evaluated the chronic ankle sprain (more than 3 years) patients with marked ankle instability tested by varus stress test and anterior draw test from March 2000 to December 2005. Eighty-nine patients (104 ankle) were evaluated and there were 38 males and 51 females. The mean age of patient at the time of diagnosis was 34.5 (range, 18 to 56 years). The average duration of morbidity was 7 years and 3 months (range, 3 years and 3 months to 21 years). The patients who had history of dislocation, fracture, malalignment, operated patients, and rheumatoid ones were excluded. Plain radiographs of AP, lateral, oblique and mortise view were checked. Results: Radilologic abnormalities were found at 74 ankles (71%) among 104 ankles. Frequent sequences of location were anterior talotibial osteophyte, medial malleolar osteophyte, Os subfibulare, lateral malleolar osteophyte. Posteior osteophyte, ankle arthritis, talar articular defect were rarely found. Conclusion: Seventy-one percent among patients with chronic ankle sprain and marked ankle instability showed more than one radiologic abnormalities. Thus, more exclusive and accurate ankle examination should be performed in these patients.

Purpose: This retrospective study reports the intermediate-term clinical outcomes including the practical function in daily and sports activities after total ankle arthroplasty for end-stage rheumatoid arthritis, as well as the effects of modification of perioperative anti-rheumatic medications. Materials and Methods: Twelve patients were followed for a minimum of 2 years after total ankle replacement for end-stage rheumatoid arthritis. Perioperative anti-rheumatic medications in all patients were modified based on a specific guideline. Clinical evaluations consisted of American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM) scores. Periodic radiographic evaluation was conducted to detect changes in ankle alignment and postoperative complications. Results: Mean AOFAS, FAOS, and FAAM scores improved significantly from 37.5 to 81.2, 39.1 to 72.4, and 33.8 to 64.0 points at final follow-up, respectively (p<0.001). Functional outcomes in daily and sports activities at final follow-up were found to be 76.5 and 55.8 points for the FAOS and 70.5 and 57.5 points for the FAAM, respectively. As early postoperative complications, there was one case of local wound necrosis, one case of medial malleolar fracture, and one case of deep peroneal nerve injury. Radiological evaluation revealed two cases of asymptomatic heterotopic ossification and one case of progressive arthritis in the talonavicular joint. Reoperation was performed in only one patient (8.3%) with a medial soft tissue impingement at a mean of 35.6 months follow-up. Conclusion: Total ankle arthroplasty appears to be an effective surgical option for end-stage rheumatoid arthritis. Practical functions in daily and sports activities were significantly improved at intermediate-term follow-up. Modification of perioperative anti-rheumatic medications can be one of the solutions to reduce the postoperative complication rate.

Soft-tissue deficits over the plantar forefoot, plantar heel, Achilles tendon, and distal parts of lower leg are often troublesome to cover with a simple graft or local flap due to limited mobility of surrounding skin and poor circulation in these area. Soft-tissue reconstruction in these regions should provide tissue components similar to the original lost tissue, supply durability and minimal protective pressure sensation and result in a donor site that is well tolerated and treated. We analysed 7 cases that were treated with the Instep flap due to soft-tissue defects over these regions from July of 1990 to July of 1993. All flaps were viable and successful at follow-up. 1. The age ranged from 9 years to 60 years, and 6 cases were male and 1 case female. 2. The sites of soft-tissue loss were the plantar forefoot(1 case), plantar heel(3 cases), Achilles tendon(2 cases), and distal parts of lower leg(1 case). 3. The causes of soft-tissue loss were simple soft-tissue crushing injury(1 case), crushing injury of the 1st toe(1 case) and posttraumatic infection and necrosis(5 cases). 4. The associated injury were open distal tibio-fibula, fracture(2 cases), medial malleolar fracture of the ankle(1 case), Achilles tendon rupture(2 case) and 1st metatarso-phalangeal disarticulation(1 case). 5. The size of flap was from $3{\times}4cm$ to $5{\times}10cm$(average $4{\times}5.6cm)$. 6. In 7 cases, we were not to find post-operative necrosis and infection, non-viability, limitation of ankle joint, and gait disturbance caused by the Instep flap surgery. 7. This study demonstrates that the Instep flap should be considered as another valuable technique in reconstruction of these regions.

Purpose: The purpose of this study is to compare the two prosthesis that used for total ankle arthroplasty. Materials and Methods: From Sept. 2003 to Jun 2006, 13 patients and 14 ankles that could be follow up more than 1 months. Semiconstrained type (Group I, 7 cases) and Unconstrained type (Group II, 7 cases) were used for total ankle arthroplasty. Mean age was 63.2 year-old, 12 ankles are men and 2 ankles were women. Mean follow up periods were 29 months. The criteria to compare the clinical result were postoperative range of motion, AOFAS score and residual bone stock of medial malleolus. Results: Postoperative range of motion of group I was $43.6{\pm}9.4$ degrees and of group II was $50.7{\pm}7.3$ degrees (p=0.115). Postoperative AOFAS score of group I was $77.1{\pm}13.0$ points and of group II was $86.0{\pm}5.7$ points (p=0.094). Resected bone stock in medial malleolus of group I was $10.7{\pm}2.5\;mm$ and of group II was $5.1{\pm}1.2\;mm$ (p=0.003). Total number of complication in our study was 9 cases. 3 cases were a malleolar fracture, two occurred at intra-operation, the other at follow-up period. Re-operation was done in 6 cases, 3 cases were calcaneal corrective osteotomy, 2 cases were resection of a heterotopic bone and one case was pedicular flap operation for skin problem. Conclusion: In our hospital, mobile bearing type prosthesis shows good result than a semiconstrained type in respect of residual bone stock in medial malleolus. Postoperative range of motion and AOFAS score between two groups shows no significant difference. But small number of patients and short term follow up period is a defect in our study, afterward more population and long term follow up period are needed.
