Purpose: To compare clinical characteristics of ganglions in hand & Foot. Materials and Methods: Seventeen cases of ganglions located in foot and fifty-five cases in hand. Excised from Mar.1988 to Apr.2003, were included in the study. The clinical characteristics and recurrence ratio were evaluated Results: The mean size of 2.2 cm in hand and 2.5 cm in foot. The most common area of ganglions are dorsum of foot and wrist. The cosmetic problem of palpable mass is the primary chief complaint of ganglions on hand and the pain is that of foot. The recurrence was found in 5 cases in hand and 4 cases in foot. The recurrence was related to incomplete excision of ganglion in foot and the large size of ganglion and incomplete excision of ganglion in hand. Conclusion: recurrence ratio in the cases of foot is higher than that of hand. The ganglions in foot and hand need to treated by meticulous surgical excision to prevent the recurrence.

In patients with diabetic foot, ulceration and amputation are the most serious consequences and can lead to morbidity and disability. Peripheral arterial sclerosis, peripheral neuropathy, and foot deformities are major causes of foot problems. Foot deformities, following autonomic and motor neuropathy, lead to development of over-pressured focal lesions causing the diabetic foot to be easily injured within the shoe while walking. Wound healing in these patients can be difficult due to impaired phagocytic activity, malnutrition, and ischemia. Correction of deformity or shoe modification to relieve the pressure of over-pressured points is necessary for ulcer management. Application of selective dressings that allow a moist environment following complete debridement of the necrotic tissue is mandatory. In the case of a large soft tissue defect, performance of a wound coverage procedure by either a distant flap operation or a skin graft is necessary. Patients with a Charcot joint should be stabilized and consolidated into a plantigrade foot. The bony prominence of a Charcot foot can be corrected by a bumpectomy in order to prevent ulceration. The most effective management of the diabetic foot is ulcer prevention: controlling blood sugar levels and neuropathic pain, smoking cessation, stretching exercises, frequent examination of the foot, and appropriate education regarding footwear.

Purpose: To evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) for postoperative pain after surgery around ankle. Materials and Methods: We included 21 patients who performed an operation around ankle from 2009 to 2013. 4 times ESWT were applied to the patients who have tenderness more than visual analog scale (VAS) point 4. We evaluated the VAS at each sessions and final follow-up, and American Orthopedic Foot and Ankle Society ankle-hindfoot score (AFOAS) was checked at preoperative and final follow-up. Patient's satisfaction and complications were surveyed. Results: Preoperative VAS was mean 4.7, postoperative pain VAS was mean 6.0 at 4.5 months follow-up. The VAS after ESWT each session at 1, 2, 3 weeks and final follow-up were 4.8, 3.2, 2.3, 2.9, respectively. Mean final follow-up period was 9.4 months. Final VAS were significantly decreased (p<0.001). Final VAS were increased from VAS at last session of ESWT, however, not significant (p=0.189). AOFAS significantly improved from preoperative 60 to final follow-up 86 (p<0.001). Excellent was 12 patients (57%), good was 4 patients (19%), no change was 3 patients (14%) and poor was 2 patients (9%). 1 patient complained a dizziness and nausea during ESWT. Conclusion: ESWT for postoperative pain after ankle surgery shows satisfactory pain reduction in 76% of all patients without severe complication.

Background: Zhongyi paste is a traditional Chinese medicine herbal paste that is externally applied to reduce inflammation and relieve pain. Methods: An acute foot swelling inflammation model in C57BL/6J mice was established by carrageenan-induced pathogenesis. Zhongyi paste raised the pain threshold and also reduced the degree of swelling in mice with carrageenan-induced foot swelling. Results: Analysis indicated that serum tumor necrosis factor-alpha, interleukin-1 beta, and prostaglandin E₂ (PGE₂) cytokine levels and PGE₂ levels in the paw tissue of the mice were decreased by Zhongyi paste treatment. The quantitative polymerase chain reaction and western blot results showed that Zhongyi paste downregulated the mRNA and protein expression of extracellular signal-regulated kinase 1/2 (ERK1/2), and cyclooxygenase-2 (COX-2), and also downregulated the mRNA expression of PGE₂. At the same time, the Zhongyi paste exerted a stronger effect as an external drug than that of indomethacin, which is an oral drug, and voltaren, which is an externally applied drug. Conclusions: Our results indicated that Zhongyi paste is a very effective drug to reduce inflammatory swelling of the foot, and its mechanism of action is related to regulation of the ERK1/2-COX-2-PGE₂ pathway.

In athletes, repetitive low-energy impacts in plantar lesion lead often to tendinitis, stress fracture, or overuse syndrome. The major cause of heel pain in athletes is plantar fasciitis. And it is most often attributable to repetitive low energy impact, but the vast majority patients with heel pain achieve symptomatic relief with conservative treatment and return to full activities. Not commonly, Nerve entrapment may be occurred from repetitive low energy trauma in athletes, and is not as easily diagnosed. The authors observed a basketball player who complained of chronic heel pain that do not respond to conservative treatment, he had the lesions both plantar fasciitis and lateral plantar nerve entrapment. The authors described an unusual mechanism of entrapment of the lateral plantar nerve combined with a chronic plantar fasciitis in a basketball player and reported with review of literature.

Recently, functional insoles of wedge-type it is for the young to raise their height inserted between insole and heel cause foot pain and disease. Additionally, these have a problem with stability and excessively load-bearing during gait like high-heel shoes. In this study, we compared the changes in biomechanical characteristics of foot with different insole thickness then we will utilize for the development of the insole with the purpose of relieving the pain and disease. Subjects(male, n = 6) measured COP(center of pressure) and PCP(peak contact pressure) on the treadmill(140cm/s) using F-scan system and different insole thickness(0~50 mm) between sole and plantar surface during gait. Also, we computed changes of stresses at the foot using finite element model with various insole thickness during toe-off phase. COP moved anterior and medial direction and, PCP was increased at medial forefoot surface, $1^{st}$ and $2^{nd}$ metatarsophalangeal, ($9%{\uparrow}$) with thicker insoles and it was show sensitive increment as the insole thickness was increased from 40 mm to 50 mm. Change of the stress at the soft-tissue of plantar surface, $1^{st}$ metatarsal head represents rapid growth($36%{\uparrow}$). Also, lateral moments were increased over the 100% near the $1^{st}$ metatarsal as the insole thickness was increased from 0 mm to 30 mm. And it is show sensitive increment as the insole thickness changed 10 mm to 20 mm. As a result, it was expected that use of excessively thick insoles might cause unwanted foot pain at the forefoot region. Therefore, insole thickness under 30 mm was selected.

Injuries to the menisci occur in a variety of ways, most commonly with a twist, pivot, squat, or valgus stress to the knee. Tear patterns are classified to longitudinal, horizontal, or transverse features according to the mechanism of injury. Work-related meniscal tear usually occurs with a repetitive usage of the foot, hence it can be classified as a cumulative traumatic disorder. We found a 47 year-old female worker who had been taking charge of repetitive foot-switch stepping for 8 years. She suffered from pain in the right knee since 5 months ago. Tenderness along the medial joint line of the right knee was observed and pain was aggravated with full flexion of the right knee. On magnetic resonance imaging, high signal intensity was observed at the posterior horn of the medial meniscus of the right knee. Degenerative longitudinal and transverse complex tear in the medial meniscus was observed on arthroscopy. Arthroscopic partial meniscectomy was performed. We surveyed the work process and the health status of co-workers. It turned out that the work process was compatible to injure the meniscus and nine out of fourteen co-worker(64.3%) complained pain of the knee. No other factors related to her meniscal tear could be found except for the situation at her work. Therefore, we conclude that meniscal tear is related to the repetitive stepping of foot switch.

The population of diabetes is continuously increasing because of the economic development and the lifestyle modification. If diabetes become chronic condition, it can cause various complications. Among many other complications, diabetic foot is the most fatal issue since it may require amputation of the legs. Diabetic foot has three different types such as neuropathic, neuro-ischemic and ischemic. Among these types, patients of neuropathic foot experience sensory abnormality. Nerve conduction velocity (NCV) is used for diagnosing neuropathic foot but this method uses strong electric stimulus to cause severe pain to the patients In this study, two channel photo-plethysmography was used as noninvasive screening tool for distinguish neuropathic foot and normal group by observing blood flow of both finger and toe simultaneously.

Pseudoaneurysm of the anterior tibial artery is a rare cause of pain and swelling of the lower leg and the foot following minor sports injuries. When there is no definite musculoskeletal cause of pain, it is important to consider pseudoaneurysm. Early diagnosis and management are essential for the successful outcome. MRI and angiogram are useful for early diagnosis. We report a case of pseudoaneurysm of the anterior tibial artery following minor sports injury. The patient experienced complete relief of the symptoms after resection of the pseudoaneurysm.
