Purpose: To evaluate the clinical and radiological results of tibio-talo-calcaneal arthrodesis using ipsilateral distal fibula buttress which had advantages of extended operative field and release of contracted soft tissue. Materials and Methods: We retrospectively reviewed 4 postraumatic compartment syndrome, 2 residual poliomyelitis, 1 posttraumatic osteoarthritis with subtalar joint infection and 1 posttarumatic sciatic nerve palsy patients who underwent a tibio-talo-calcaneal arthrodesis from April, 1996 to March, 2002. Each of the cases was notable for a severe rigid equinovarus, persistent pus drainage of calcaneal area and paralytic foot. The mean duration of follow up was 18 months (range, $13{\sim}42$ months). The pain, function and alignment were evaluated by the modified ankle hindfoot scale of the American Orthopaedic Foot and Ankle Society (AOFAS) and patients satisfaction clinically. The radiological union were evaluated by plain AP and lateral radiographs. Results: The AOFAS score improved from 58 points (range, $47{\sim}78$) preoperatively to 82 (range, $60{\sim}89$) postoperatively. Patents satisfaction checked at 12 months after operation had favorable results (excellent and good 80%). Union rate was 100% radiographically and the mean duration of union was 12.5 weeks (range $8{\sim}22$ weeks). There was 2 cases of superficial pin tract infection and one protrusion of screw. Conclusion: Tibio-talo-calcaneal arthrodesis using ipsilateral distal fibula buttress was good modality of arthrodesis which provides wide operative field and release of contracted soft tissue in some cases of contracted foot.

Purpose: The aim of this study was to retrospectively evaluate the clinical and radiological results of the first metatarsophalangeal joint arthrodesis with two crossed screws fixation. Materials and Methods: We treated 23 patients (24 cases) with arthrodesis of the first metatarsophalangeal joint using two crossed screws fixation between December 2000 and May 2005. There were 3 male patients and 20 female patients. Ages ranged from 28 to 74 years (mean, 50 years). Follow-up ranged from 4.1 to 8.2 years (mean, 6.5 years). The American Orthopaedic Foot and Ankle Society (AOFAS) score and their satisfaction was evaluated clinically, foot anteroposterior and lateral radiograph, radiologically. Results: Of the 24 cases, 6 had surgery for dorsal plate and screws fixation because of failure to acquire firm fixation with two crossed screws fixation. All 6 cases acquired bony union. Fusion of the hallux first metatarsophalangeal joint occurred in 16/18 cases (89%). Nonunion occurred in 2 cases (11%) and was asymptomatic. At last follow-up, hallux valgus angle ranged from 11 to 25 degrees(mean, 17.7 degrees), dorsiflexion ranged from 15 to 25 degrees (mean, 22 degrees).The mean preoperative AOFAS score of 37 points(range, 28 to 45 points) improved to a mean of 77 points (range, 65~90 points) postoperatively. The result of the procedure as rated subjectively by the patient was excellent for 5 cases, good for 11 cases and fair for 2. Conclusion: Comparatively, the arthrodesis of the first metatarsophalangeal joint with crossed screws fixation showed a satisfactory clinical results, we thought that require technical attention for firm fixation in operation.

We report on a case of post-burn contracture and right foot deformity in a 37-year-old female who underwent two surgical interventions at the age of seven years. The patient remained well without any associated problems until she presented to our hospital at the age of 37 years with severe pain and right foot deformity. A few treatment modalities have been reported, and amputation has been suggested as the best approach. However, our patient was treated with a talonavicular arthrodesis and a soft tissue procedure, which resulted in a stable, plantigrade, and pain-free foot with an unsupported, bipedal gait.

Purpose: To determine the efficacy of the SDBBA (Subtalar distraction bone block arthrodesis) procedure on patients with late complication of intra-articular calcaneal fractures including subtalar joint arthritis and anterior ankle impingement syndrome. Materials and Methods: Five cases in which the SDBBA procedure was implemented were followed for more than one year. All five patients were male with an average age of 56. Clinically, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the pain score were assessed. Radiographically, the talocalcaneal height and the talar inclination angle were determined. Results: All five patients achieved subtalar joint fusion. The average pre-operative AOFAS score was 22.8 scores (range, 8-32 scores). At last follow-up, these scores improved to an average of 72.4 scores (range, 64-82 scores). The average pre-operative pain score was 8.2 scores (range, 7-10 scores). At last follow-up, these scores improved to an average of 13.2 (range, 12-15 scores). The average pre-operative talocalcaneal height was 72.8 mm (range, 70-77 mm), average post-operative talocalcaneal height improved to 79.8 mm (range, 78-84 mm). At final follow-up, these measurement was slightly decreased to average 78.6 mm (range, 74-83 mm). The average pre-operative talar inclination angle was 13.2 degrees (range, 12-15 degrees), average post-operative talar inclination angle improvedto 19.2 degrees (range, 15-24 degrees). At final follow-up, these measurement was slightly decreased to average 18.6 degrees (range, 12-24 degrees). Four patients achieved successful outcomes. One patient developed a wound infection with subsequent sural neuropathy as well as collapse of the bone graft. Conclusion: This study shows that the SDBBA procedure successfully restores the talocalcaneal height and tibio-talar relationship. This procedure is useful in surgically managed patients with talo-calcaneal height loss and anterior ankle impingement syndrome due to the late complications of calcaneal intra-articular fractures.

Purpose: The aim of this study is to evaluate if the Ilizarov external fixation procedure with axial compression can help to obtain fusion across the ankle joint in patients with a high risk of nonunion. Materials and Methods: From January 2006 to December 2015, the study reviewed 17 patients who underwent ankle arthropathy with a high risk of nonunion and who underwent ankle fusion using the Ilizarov external fixator with axial compression and auto bone grafting. After the lateral surface of the ankle joint was exposed through a lateral trans-fibular approach, massive removal of the articular cartilage and excision of any loose or avascular bone were done. With the cortical bone harvested from the pelvis as corticocancellous bone blocks, we inserted the two cortical blocks longitudinally into the anterior and posterior part of the free ankle space from lateral to medial to make the rectangular chamber to fill the cancellous bones. After the Ilizarov external fixator was equipped, we tightened the frame by 5 mm to compress the bone graft space. We accessed the American Orthopaedic Foot and Ankle Society (AOFAS) AnkleHindfoot score both preoperatively and postoperatively. Results: The average age at the time of operation was 63.4 years (range, 47~78 years). The mean frame time was 17.4 weeks (range, 15~23 weeks). The average follow-up period was 3.7 years (range, 2~6 years). Osseous fusion was obtained in 15 patients (88.2%). There were two stable pseudarthroses among the rheumatoid arthritis patients, and we continued their follow-up. The mean AOFAS AnkleHindfoot score improved from 48.5 to 73.7 points. Conclusion: Ankle arthrodesis using the Ilizarov external fixation with axial compression and auto bone grafting on the ankle arthropathy that had difficult conditions to achieve union is considered one of the useful methods with a correspondingly low incidence of complications.

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.

The cavus foot is a deformity characterized by an elevated medial longitudinal arch and a hindfoot varus with plantarflexed 1st ray. The etiology of cavus foot is usually related to neuromuscular disease or idiopathic cause. Thorough clinical and radiographic evaluation is required for differentiating etiology of the cavus. Most cases of cavus foot are stable and slowly progressive deformities which can initially be managed with conservative treatment including orthoses and physical therapies. Determining whether the deformity is flexible or rigid, the apex of the deformity and any muscle imbalances in foot and ankle is important for achievement of an adequately balanced plantigrade foot. Treatment should include systematic preoperative planning for selection of appropriate procedures for maintaining a functional and flexible foot with combinations of soft-tissue release, osteotomy, tendon transfer, and arthrodesis.

A tarsal coalition is an abnormal union between 2 or more tarsal bones of the hind- and midfoot, which can be congenital or acquired. The documented overall incidence of tarsal coalition is 1% or less. The resulting abnormal articulation leads to accelerated degeneration within adjacent joint. Pain is often diffuse, exacerbated by strenuous activity or following an ankle sprain. The findings on physical examination is protruded mass, diminished range of motion of the involved joint. It is possible to identify of tarsal coalitions with conventional radiography, but CT scanning necessary to evaluate of the size, location, characteristic and preoperative planning of tarsal coalitions. The initial treatment for a tarsal coalition is conservative, but tarsal coalitions unresponsive to conservative treatment, are managed by coalition resection, or arthrodesis in case of presence of degenerative changes.

Purpose: To investigate the short term result of the first metatarsophalangeal arthrodesis for treating the hallux valgus deformity of rheumatoid arthritis, using a lag screw and dorsal mini-plate. Materials and Methods: From December 1999 to September 2001, The first metatarsophalangeal arthrodesis of 14 cases (9 patients) was underwent, using a lag screw and dorsal mini-plate. The follow-up period was averaged in 14.6 months. The subjective findings with respect to pain, functional aspect of ability to stand and walk, and to shoe-wearing were evaluated. The objective findings, such as the gross alignment and the radiological measurements for the hallux valgus angle, 1,2 intermetatarsal angle, and dorsiflexion angle were also studied. Results: After the arthrodesis of the first metatarsophalangeal joint, the subjective improvement in pain, function and alignment was graded as excellent in seven (50%) feet, good in seven (50%) feet, and fair or poor in none. The hallux valgus angle and 1,2 intermetatarsal angle were reduced from $44.1{\pm}7.1$ and $15.5{\pm}6.2$ degrees to $13.6{\pm}2.6$ and $10.2{\pm}2.2$ degrees respectively. The dorsiflexion angle was measured in $20.3{\pm}3.7$ degrees after the fusion. The radiological fusion was observed at average 8 weeks after the operation in all cases. The overall complication of the procedure was few, except the delayed wound healing in one. Conclusion: The arthrodesis of the first metatarsophalangeal joint using a lag screw and dorsal mini-plate was regarded as an excellent method of various operative modalities to correct the rheumatoid hallux valgus deformity.
