There may be complications after comminuted or intraarticular calcaneal fracture regardless of the initial treatment. Transcalcaneal talonavicular dislocation is rarely reported severe form of calcaneal fracture. We experienced a neglected transcalcaneal talonavicular subluxation case, who had been treated for intraarticular calcaneal fracture conservatively. Subtalar distraction bone block fusion was done for calcaneal malunion with talonavicular subluxation. Inspite of successful subtalar fusion, pain was persisted because of talonavicular re-subluxation with arthritis and calcaneocuboid arthritis. So, second operation, the talonavicular and calcaneocuboid fusion, was done. After union achieved, the patient's foot pain was improved. Calcaneal malunion combined with talonavicular subluxation and unstable transverse tarsal joint, such as this case, initial triple arthrodesis could be considered.

Calcaneal fractures account for 2% of all fractures and approximately 60 to 70% of tarsal fractures. These fractures typically are the result of high-energy injury, such as a motor vehicle accident or a fall from a height. The potential for disabling malunion following intrarticular displaced calcaneal fracture is high, regardless of treatment. Fracture displacement typically results in loss of hindfoot height, varus and widening of the hindfoot, with possible subfibular impingement and irritation of the peroneal tendon and/or sural nerve. Frequently, subtalar joint develops posttraumatic arthritis. In symptomatic patients with calcaneal malunion, systemic evaluation is required to determine the source of pain. Nonsurgical treatment, such as activity and shoe modification, bracing, orthoses, and injection, is effective in many patients. Surgical treatment may involve simple ostectomy, subtalar arthrodesis with or without distraction, or corrective calcaneal osteotomy. A high rate of successful arthrodesis and of patient satisfaction has been reported with surgical manamgent.

Quite high prevalence of acute and chronic complications of calcaneal fractures has been reported. Acute complications include blisters, wound necrosis or infection. Late complications include subtalar arthritis, calcaneal malunion, lateral subfibular impingement, tendon problems, sural nerve complications. There are many surgical or nonsurgical treatment modalities to manage those complications. However strategic initial surgical approach with gentle soft tissue handling accompanied by comprehensive understanding about numerous complications might be the best tool to achieve pain free and functional heel after treating calcaneal fractures.

Inappropriate treatment for calcaneus fracture may result in malunion causing long-lasting pain and functional deficits. When such complications occur, the ideal principle of management is preserving congruence and motion of adjacent joints. For three patients with calcaneus fracture malunion, subtalar joint-preserving surgery using exostectomy and corrective osteotomy was performed, and satisfactory outcomes were achieved postoperatively.

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: This study was designed to evaluate the results and efficacy of subtalar distraction two bone-block arthrodesis for calcaneal malunion. Materials and Methods: From January 2004 to June 2007, we operated on 8 patients (12 cases). There were 7 male patients and 1 female patient; their mean age was 42 years. 8 cases among them were operated initially. The period between initial injury and arthrodesis was 21 months. At an average follow up was 19 months. In operation, we used extensile lateral approach and arthrodesis was performed through tricortical two bone-block and cannulated screws. The Ankle-Hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT were examined union and various parameters. Results: All cases achieved radiologic union at the final follow-up. The mean Ankle-hindfoot scale (maximum of 94 points) increased from 43.4 points preoperatively to 84 points at the final follow-up. The radiologic analysis of the pre- and postoperative standing lateral radiographs showed and average increase of 5.5 mm in talo-calcaneal height, $5.1^{\circ}$ in talocalcaneal angle, $6.1^{\circ}$ in talar declination angle and decrease of $5.7^{\circ}$ in talo-first metatarsal angle. Conclusion: The short term results of subtalar distraction two bone-block arthrodesis is promising, but longer follow-up was needed.

Purpose: The treatment of calcaneal fractures remains a controversy in orthopaedic field because of its complications. The purpose of this study is to evaluate the efficacy of the treatment of calcaneal fractures and its complications. Materials and Methods: Clinical and radiological results were retrospectively analyzed in 28 patients, 34 cases with fractures of calcaneus which were treated in our department from September 1998 to march 2003. Results: According to the Creighton-Nebraska Foundation Assessment score, there were 3 excellent, 11 good, and 12 fair 6 poor results. Bohler angle was corrected from $8.3^{\circ}$ to $18.3^{\circ}$, Gissane angle was corrected from $121^{\circ}$ to $135^{\circ}$, and calcaneal width was corrected from 46.8mm to 37mm. Conclusion: Open reduction and internal fixation for joint depression type calcaneal fractures thought to be a good method of treatment. Closed reduction and percutaneous axial pinning should be chosed in selected cases of tongue type fractures. In treatment of complicated calcaneal fractures as malunion, subtalar distraction arthrodesis and lateral wall exostectomy will reduce disability of the disease.

Purpose: To report the clinical results of tibio-talo-calcaneal arthrodesis fixed with multiple cannulated screws for the cases of painful ankle and hindfoot arthropathy regardless of any deformity or instability. Materials and Methods: A retrospective analysis was performed upon 10 patients that underwent tibio-talo-calcaneal arthrodesis from October 1999 to May 2006. There were 4 males and 6 females, with an average age of 63 years (43-70). The etioloty of arthrodesis included 5 osteoarthritis, 2 Charcot joints, 1 rheumatoid arthritis, 1 Tbc arthritis and 1 residual poliomyelitis. Chief complaints were pain in 9 cases and instability in 1 case. Three patients had combined severe varus deformity. Tibio-talo-calcaneal arthrodesis using multiple cannulated screws was performed by transfibular approach for all cases and short leg cast was applied for 12 weeks postoperatively. Results: The average follow-up period was 16.5 months (12-26 months). VAS pain score was average 8.2 (7-10) and modified AOFAS score was average 25 (8-40, total 86) preoperatively. At final follow-up, VAS score was average 1.0 (0-3) and AOFAS score improved to average 66 (58-75). There were 4 complications: 2 nonunion, 1 tibia stress fracture and 1 malunion. Seven of 8 patients were satisfied with the results at final follow-up. Conclusion: Fixation with multiple cannulated screws for tibio-talo-calcaneal arthrodesis through transfibular approach is a recommendable surgical option.

Past research has reported that the common causes of ankle arthritis include trauma, congenital deformity, and degeneration. Among them, fracture-induced post-traumatic arthritis is most common. For patients with ankle fractures, an anatomical reduction is performed through surgical treatment. However, insufficient reduction or malunion of the fracture site may change the alignment of the ankle joint, resulting in valgus or varus deformities. Currently, most operative options for valgus arthritis aim to either restore joint alignment and/or reduce the uneven load on the cartilage. In this report, we would like to share our clinical experience of a patient with posttraumatic valgus ankle arthritis caused by severely comminuted fracture and dislocation. A satisfactory outcome could be obtained with combined fibular lengthening osteotomy and medial displacement calcaneal osteotomy.

Purpose: Subtalar distraction arthrodesis is useful treatment option for restore hindfoot alignment. but, using structural autograft have high risk of donor site morbidity. Recently, by replacing the structural allograft has been reported satisfactory clinical results. Therefore, the authors reviewed the results of subtalar distraction arthrodesis using a structural allograft, retrospectively. Materials and Methods: From January 2008 to May 2010, 12 patients (12 feets; 9 male, 3 female) underwent subtalar distraction arthrodesis using frozen structural allograft. 9 cases were calcaneal malunion, 2 were nonunion or malunion after subtalar arthrodesis, 1 was other cause. Mean age was 38.9 (12~66) years old and follow up period was 16.5 (12~36) months. Surgical was performed with posterolateral approach and tricortical allobone block of frozen femoral neck was used. Analysis was done with retorspective manner to evaluate preoperative, postoperative, and final follow up radiologic measurement and AOFAS ankle-hindfoot scale. Results: There was statistically significant increase (p<0.05) of ankle-hindfoot scale from preoperative 27.5 points to postoperative 72.5 points, talocalcaneal height by 6.62 mm, calcaneal pitch angle by 5.73 degrees, lateral talocalcaneal angle by 6.38 degrees and significant decrease (p<0.05) of tali-1st metatarsal angle by 5.23 degrees. 11 feet (91.7%) acquired bony union and it takes average 5.1 months. Final post-operative result revealed talocalcaneal height changed by 2.57 mm, calcaneal pitch anble, lateral talocalcaneal angle, talar-1st metatarsal angle were changed by 2.63 degrees, 1.62 degrees, 1.18 degrees, respectively (p<0.05). 3 cases of partial osteonecrosis of posterior facet of calcaneus were observed in operation field, 4 cases of complication were developed (1 case of nonunion, 1 collapse of allobone graft, 1 screw loosening, 1 superficial skin necrosis). Conclusion: Subtalar distraction arthrodesis using frozen structural allobone graft is useful alternative treatment method of arthrodesis with structural autobone graft.
