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.

Ankle arthrodesis has been used frequently for end-stage ankle arthritis that does not respond to conservative treatment. On the other hand, there are concerns regarding the degenerative changes to the adjacent joint, such as the subtalar or talonavicular joint, due to the altered biomechanics after the loss of ankle motion. Because the arthrodesis for these midtarsal joints may overload stress on another contiguous joint, a salvage procedure should be considered rather than joint sacrificing. This paper reports a case of talonavicular arthritis after malunited ankle arthrodesis that was treated with interpositional arthroplasty using the tibialis anterior tendon.

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.

Purpose: To analyze the overall clinical outcome, overall assessment, and patient's satisfaction rate of subtalar arthrodesis using the cannulated compression screw. Materials and Methods: This study is based on 17 patients, 17 feet who underwent subtalar arthrodesis using the cannulated compression screw from March, 1997 to March, 2004 with at least 1 year follow-up. The average follow-up period was 33.0 months (12 to 72 months). Functional results were assessed using the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot (AOFAS) score, and Visual Analysis Scale (VAS) pain score, patients' returning to previous occupation and patients' satisfaction rate were also evaluated. Results: The mean AOFAS scores at final follow-up were 80.4 points (range $66{\sim}92$). The satisfactory rates were as follow. Thirteen patients (76.4%) were at least satisfied with surgical result at final follow-up. Patients' VAS pain score was average 2.8 points ($1{\sim}6$). Fourteen (82.3%) patients returned to previous job at mean postoperative period of 11.3 months (range 3-18 months). Patients' work efficiency after returning to previous occupation was 68.7% (range $33{\sim}100%$). There were 9 complications which were 3 cases of sural nerve injury, 1 case of valgus malunion, and 5 cases of the hindfoot residual pain. Conclusion: We obtained the satisfactory functional results with relatively high patient satisfaction rate of 76%. So we conclude that subtalar arthrodesis using the cannulated compression screw is a reliable method for addressing the painful end-stage subtalar osteoarthritis and unreconstructible comminuted calcaneal fractures. However we also found out that average 11 months were necessary for patients to return to their job.

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.

An eight-month old female mixed breed dog was presented to the at Gyeongsang National University Animal Hospital, for tarsocrural arthrodesis. Previously the dog had been presented to a local animal clinic. Orthopedic and blood examinations were conducted. There was absent response of conscious proprioception on the right tarsocrural articulation. The dog stood knuckled onto the digits and had hock dropped but showed normal values in WBC, RBC, Hb, PCV, BUN, creatine, glucose, cholesterol, AST and ALT analyses. The dog was anesthetized and prepared for aseptic surgery. Steinmann pin and Joshi external fixators were applied(bilaterally). 11 weeks after the operation, the external fixators were removed from the bones. The hock dropped was well stabilized, but mild knuckling of distal metatarsopharangeal joint was remained.

These days, spinal interbody arthrodesis using fusion cage is very popular. The cage used for the spinal interbody arthrodesis is mainly inserted from the posterior of the spine. Accordingly, there could possibly occur damages at posterior and results in instability of structure. Moreover, one or two cages are inserted depending on the patients. In this study, it is attempted to evaluate the stability quantitatively by comparing two cases where one and two cages are inserted. For this purpose, a very fine 3-dimensional finite element model of vertebra is generated from the MRI data. From this vertebra model, two models are made: one with one cage and the other with two cages. Finally, finite element analys is performed for these two models and both of the mechanical behaviors are examined In addition, the effect on the stability is evaluated and compared quantitatively.

Total ankle replacement has been performed for treatment of end stage arthritis of the ankle, hopefully being an alternative to ankle arthrodesis. However, due to its high failure rates, earlier versions of ankle replacements were not regarded as successful procedures. The latest design has shown increasingly positive results. Total joint replacement of the ankle itself is still regarded as a demanding procedure and much more challenging than that of the hip and knee in many aspects. Several studies, however, have pointed out that it is becoming the viable, accepted alternative for arthrodesis with advanced implants, appropriate patient selection, and proper training experience of procedures. Compared with arthrodesis, it shows equal or better outcomes in pain relief, range of motion, and patient's satisfaction. We are attempting to review its biomechanical characteristics, implant design, indications, complications, clinical outcomes, and survival rate.
