We analyzed the impulse on 24 sensors location under the foot using the Parotec system for the investigation of the relationship between the shoe type and the foot pathologies. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with the impulse distribution of the sport shoe, greater impulses were shown at the 1$^{st}$ phalange and the 1$^{st}$ metatarsal-phalangeal head in high-heel shoes, lateral tarsal bone and medial metatarsal bone in platform shoe, medial tarsal bone in inline-skate, and medial tarsal bone and 1st phalange in heelys shoe. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.ies.

We analyzed the pressure, impulse on 24 sensors location under the foot using the Parolee system. Total 7 kinds of shoes, i.e. sport shoe, high heel shoes (5cm heel, 8cm heel, 13cm heel), platform shoe, inline skate, and heelys were evaluated for 20 normal subjects. Compared with those of sport shoe, greater pressure and impulse were shown on the 1 st phalange and the 1 st metatarsal head and greater impulse on the medial tarsal bone in high-heel shoes. Greater pressure and impulse were shown on medial metatarsal bone and the lateral tarsal bone in platform shoe. Greater impulse was shown on the medial tarsal bone in inline-skate. Heelys shoe showed smaller impulse on the central area of foot. The result of this study is expected to provide useful information about the relationship between the shoe type and the foot pathologies.

Objectives : This study reports the clinical effects of miniscalpel needle therapy in patients with carpal tunnel or tarsal tunnel syndrome. Methods : Three patients with carpal tunnel syndrome (CTS) or tarsal tunnel syndrome (TTS) (first case, patient with CTS and TTS; second case, patient with CTS; and third case, patient with TTS) were treated with miniscalpel needle (MSN) therapy and integrative Korean medical treatment. The Numeric Rating Scale (NRS), Neuropathic Pain Scale (NPS), Boston scale score, and AOFAS (American Orthopaedic Foot and Ankle Society) ankle-hindfoot score were measured. Results : In general, outcome measures after treatment showed improvement in all cases. In the first case (CTS and TTS), scores on the NRS, NPS, and Boston scale decreased, and AOFAS ankle-hind foot scores increased. In addition, Tinel's sign showed improvement. In the second case (CTS), scores on the NRS, NPS, and Boston scale, and Tinel's sign, were decreased. In the third case (TTS), scores on the NRS and NPS, and Tinel's sign, showed improvement, and AOFAS ankle-hind foot scores were increased. Conclusion : These results suggest that MSN therapy has a meaningful clinical effect in CTS and TTS.

Background To present the outcomes of the tarsal switch procedure using an anterior approach to correct severe ptosis with poor levator muscle function (<4 mm) with absent or poor Bell's phenomenon. Methods This retrospective case series included 11 patients with severe neurogenic or acquired myogenic palpebral ptosis. All patients underwent the tarsal switch procedure through an anterior approach from 2012 to 2015. Margin reflex distance (MRD1 and MRD2) and the palpebral fissure were evaluated preoperatively and postoperatively. Data were compared using the Wilcoxon signed-rank test. P-values <0.05 were considered to indicate statistical significance. Results Surgery was performed on 18 eyelids (11 patients). The median age at surgery was 57 years (range, 29-86 years). Four patients had unilateral ptosis and seven had bilateral ptosis. Nine patients had myogenic ptosis and two had neurogenic ptosis. Postoperatively, the chin-up position improved in all patients. The MRD1 increased statistically significantly, from 0 mm preoperatively to 1.0 mm postoperatively (P=0.001). The MRD2 decreased statistically significantly, from 4.5 mm preoperatively to 3.0 mm postoperatively (P=0.001). The palpebral fissure did not change (4.0 mm preoperatively to 4.0 mm postoperatively) (P=0.13). Conclusions The tarsal switch procedure through an anterior approach is an effective alternative for correcting severe ptosis, especially neurogenic or acquired myogenic ptosis. This procedure can be performed with minimal risk of ocular surface exposure and provides stable outcomes.

Background: Compared with conventional closed therapy, acupotomy has the advantages of lower cost, convenient application, and better single and long-term effects. The aim of this study was to explore the clinical effect of acupotomy in the treatment of Tarsal Tunnel syndrome. Methods: There were 80 patients enrolled into the study who were randomly assigned to either the acupotomy or closed therapy group, with 40 patients in each group. The acupotomy group was treated once every 6 days, on 3 occasions for the duration of treatment, and the closed therapy group was treated twice a week, for 3 weeks as the course of treatment. The effects of treatment were analyzed and evaluated according to the standard of curative effect. Results: The "cure rate" of the number of patients in the acupotomy group whose symptoms had completely disappeared (13 patient out of 39) was higher than the closed therapy group (1 patient out of 39), and this difference was significant (p < 0.01). The number of patients in the acupotomy group who did not benefit from the therapy (5 patients) was significantly lower than the closed therapy group (15 patients; p < 0.05). The total number of patients in the acupotomy group who benefitted from the therapy (34 patients) resulted in an effective rate of 87.18%, which was higher than the closed therapy group (24 patients; 61.53%). The difference was statistically significant (p < 0.05). Conclusion: Acupotomy is effective in the treatment of Tarsal Tunnel syndrome, was superior to traditional closed therapy, and is worthy of clinical application.

Purpose: The purpose of this study was to evaluate the results of surgical treatments for tarsal coalitions. Materials and Methods: A retrospective study was conducted between October 1995 and September 2002. Four cases of talocalcaneal coalitions and two cases of calcaneonavicular coalitions were included. We did bone excision for three cases of talocalcaneal coalitions and two cases of calcaneonavicular coalitions. In one case of talocalcaneal coalition, we did subtalar fusion. Follow-up averaged 43 months. We evaluated both the patients' satisfaction rates by Mann and Reynolds scorring and compared the radiographic results between preoperative and final radiography. Results: The satisfaction outcomes at the last follow-up were two excellent and two good in talocalcaneal coalitions and all excellent in calcaneonavicular coalitions. Two cases of talocalcaneal coalition who did excision of coalition complained mild pain in hindfoot, however, symptoms improved than preoperation. In calcaneonavicular coalition, pain is subsided at mean post-operative 13 weeks. During follow-up period, there were no radiographic changes and recurrence in all cases. Conclusion: In small cases, we think the cause of subsidence of symptoms maybe reconstruction of normal joint motion after excision of tarsal coalition. But, we try to warn the patients with talocalcaneal coalition that the symptom may not be completely subsided after the excision of coalitions.

It was well known that arthrodesis of the tarsal joint is an exellent procedure to correct the flatfoot deformity for relieving pain. Recently, concept of the selective tarsal joint fusion instead of the triple fusion was developedto preserve the joint motion. To investigate and compare the effect of the each different tarsal fusion, we measured the strain at the spring ligament, medial roof of the medial longitudianl arch. Five fresh frozen cadevar foot specimens, with distal half of the tibia were utilized. The superomedial portion of the spring ligament complex was dissected from the origin to the insertion. For each specimen, a calibrated open liquid metal strain guage was secured along the length of the superomedial portion. Under the specially devised test rig, measurement of the strain was taken at each test condition from the tare weight 18.2 lb followed by 38.2 lb., 82.2 lb and a maximum loads of 134.6 lb. : 1) unfused condition, 2) isolated subtalar fusion 3) isolated talonavicular fusion 4) combined subtalar and talonavicular fusion 5) triple fusion. Statistics showed that siginificant reduction in strain following the triple fusion, and from the subtalar fusion to triple fusion.

Avascular necrosis is a significant late complication of talar neck fracture. However, treatment for early stage avascular necrosis has been not established. Two patients with post-traumatic avascular necrosis of talus treated with vascular pedicle graft using lateral tarsal artery were reviewed to determine the efficacy of procedure. The procedure involved grafting the lateral tarsal artery and vein into a hole made in the talus through a anterolateral approach. Follow-up was 12 and 24 months respectively. Two patients had significant pain relief, improved function, no worsening of their radiologic staging. The results are promising enough to recommend consideration of this procedure in early stages of avascular necrosis.

For design of early childhood children's footwear, this study was to analyze the properties of their foot. This study was performed in 200 male and 200 female early childhood children from 3 and 6 years old lived in susan urban area. There were measured 17 items of the foot and calculated 4 indexs for analysis. The result was as follows; 1 The growth rate differs from the sites of a foot. According to the growth of age, early childhood children's foot are more slender. 2. The average of foot print angle is $15~27^{\circ}$ and it is flat. Among the age groups, the numbers of 4 kinds of foot print angle are different siginificantly. 3. The average of metatarso phalanx angle is $174~178^{\circ}$ that is higher than adults'. 4. There are no significant difference between male children's foot and female childen's one except tarsal circumference and tarsal height. Tarsal part of male children is higher and ticket than female children's. 5. Because some of 3~6 age groups belong to the one foot length group, we should consider the age properties of foot in order to design footwears. When the size of footwear is divided by only foot length, the ranges of another measurements are larger than the range of foot length.

Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy that occurs in the ankle. Previous studies reported that this disease was due to physiologic factors and structural lesions in the ankle or foot. The authors investigated the causative factors of TTS and their frequency via operative findings. The diagnostic value of MRI was also evaluated based on the concordance between the operative findings and the MRI findings. Methods: This study was performed in retrospective by using medical record of the patients who underwent operations with TTS from August 2003 to May 2010. Physical examination, nerve conduction study, and MRI were conducted on patients who visited department of neurology or orthopedic surgery due to pain and sensory abnormality of their ankle and foot. Results: 34 patients underwent the operation. Ganglion accounted for the largest portion of the operative findings. In addition, varicose veins, intrinsic foot muscle hypertrophy, tenosynovitis, and fascia thickening were mainly observed. Of the 34 patients, 33 patients underwent pre-operative MRI, of whom 18 patients showed MRI findings consistent with the operative findings. Conclusions: Space-occupying lesions accounted for the majority of the causative factors in TTS patients who underwent the surgical treatment. In this study, the MRI appeared useful for identifying causes of TTS.
