Purpose: To evaluate the results of conservative treatment of zone I, II $5^{th}$ metatarsal base fracture. Materials and Methods: Between May 2004 and June 2010, a total of 58 patients of zone I, II $5^{th}$ metatarsal base fractures were included in this study. The mean length of follow-up was 13.5 months (12~36 months). All of the patients were treated with full-weight-bearing short leg cast immobilization for 4 weeks and wooden sole shoes for 4 weeks. The results were evaluated about the radiographic union, the midfoot scale of American Orthopaedic Foot and Ankle Society (AOFAS), the tenderness on fracture site and other complications. Results: All patients were able to return to their prior levels of activity. The mean time for union as shown on radiographs was 45.5 days, and the mean midfoot scale of AOFAS was 99.7 points. There were no nonunions or refractures during the follow-up. Conclusion: The conservative treatment with full-weight-bearing short leg cast and wooden sole shoes seems to give good results for zone I, II $5^{th}$ metatarsal base fracture.

Foot ulceration results in substantial morbidity in patients with peripheral neuropathy. The purpose of this study was to find the relationship of plantar foot pressures during walking to plantar ulceration in patients with Hansen's disease. The subjects were recuruited from two Welfare Clinic for Hansen's disease in Wonju and Uiwang city. Ten subjects (5 females, 5 males) with plantar ulceration and a mean age of 63 years were evaluated in this study. The mean duration of Hansen's disease in these subjects was 30 years. Plantar pressures were measured during self-selected comfortable walking speed by using MatScan system. Three subjects had plantar ulceration under the first metatarsal head. Five subjects had plantar ulceration under the second and third metatarsal head. Two subjects had plantar ulcers under the fifth metatarsal head. Eight of 10 subjects had plantar ulceration at highest pressure point that measured during walking. This result suggests that the abnormal high plantar pressure could be related factor to plantar ulceration in patients with Hansen's disease. Also the foot pressure measurement may be useful to evaluate the risk of plantar ulceration in patients with Hansen's disease.

Purpose: The purpose of this study was to compare the pathway of COP and plantar foot pressure and to determine the correlation between plantar regions during the ascending and descending of a ramp. Methods: Fifteen healthy adults who had no musculoskeletal problems participated in our study. They were asked to walk on a level surface and on an ascending and descending ramp in their bare feet. Pathway of COP and plantar foot pressures were recorded using the Matscan system (Tekscan, Boston, USA). For pressure measurements, the plantar foot surface was divided into seven regions: two toe regions, three forefoot regions, a midfoot region, and a heel region. To determine whether there was a statistically significant difference between pathway of COP and plantar foot pressures during walking, we used repeated measuremes ANOVA. Results: In comparison to results for a level walking, pathway of COP while ascending a ramp had a tendency to be shifted medially in the forefoot and became longer till the big toe. Pathway of COP while descending a ramp also was shifted medially, but ended in the forefoot. Plantar foot pressure of the second and third metatarsal head and the fourth and fifth metatarsal heads was significantly decreased while descending the ramp. Conclusion: These results indicated that plantar foot pressure is changed while ascending and descending a ramp and demonstrated that ramp walking can affect the structure and function of the foot. Therefore, gait environment is associated with significant changes in foot characteristics, which contribute to altered plantar loading patterns during gait.

The purpose of this study was to find the effect of rear foot wedge angle on peak plantar pressures on the forefoot during walking. Twenty normal healthy subjects (10 female, 10 male) were recruited. Peak plantar pressure was measured using pressure distribution platforms (MatScan system) in medial forefoot (under the first, second metatarsal head) and lateral forefoot (under the third, fourth, fifth metatarsal head). The subjects walked at the comfortable velocity under seven conditions; bare footed, $5^{\circ}$, $10^{\circ}$ and $15^{\circ}$ wedges under the medial and lateral sides of the hindfoot. The three averaged peak plantar pressures were collected at each condition at stance and toe off phases. The results showed that a significant increase in lateral forefoot plantar peak pressure investigated in the medial wedge and a significant decrease in lateral forefoot plantar peak pressure investigated in lateral wedge at stance phase (p<.05). These results suggest that rear foot wedge may be useful to modify the peak plantar pressure on the forefoot.

The foot type is classified into normal, high or low arch according to either foot print or medial longitudinal arch (MLA) height. Plantar fasciitis, heel pain, Achilles tendinitis, stress fracture, metatarsalgia, knee pain, shin splint pain, and etc are common foot disorders and associate to the foot type. The purpose of this study was to evaluate several suggested bony inclination used to classified the abnormal foot and if the arch index (AI) was correlated with foot morphology. Lateral view and dorso-plantar view of radiographic images and flatbed scanner measurements obtained from 57 college students were analyzed. Results showed that AI measured in this study was higher than Caucasian Americans and European, but similar with African. The ethnic origin could influent the AI distribution. The AI provided a simple quantitative means of assessing the structure of lateral and medial longitudinal arches. The correlation coefficients of true bone height with AI could be further improved by normalized foot width rather than foot length. AI also demonstrated as a good indicator of inclination between calcaneus-fifth metatarsal (CalM5) and calcaneus-first metatarsal (CalX), it is a good means to classify the foot type.

The purpose of this study was to determine whether a relationship existed between foot type and the location of plantar callus in healthy subjects. Twenty-five healthy subjects with plantar callus were recruited for this study. Foot deformities were classified according to the operational definitions as 1) a compensated forefoot varus, 2) an uncompensated forefoot varus or forefoot valgus, or 3) a compensated rearfoot varus. The location of plantar callus was divided into two regions. Fourteen of the 19 feet with compensated forefoot varus and six of the 9 feet showed plantar callus at the second, third or fourth metatarsal head. Five of the 6 feet with uncompensated forefoot varus and twenty of the 16 feet with forefoot valgus showed plantar callus at the first or fifth metatarsal head. A significant relationship was found between foot type and location of callus (p<.01). The results support the hypothesis that certain foot types are associated with characteristic patterns of pressure distribution and callus formation. We believe diabetic patients with insensitive feet and with the types of foot deformity should be fit with foot orthoses and footwears that accommodate their respective deformity in a position as near to the subtalar joint as possible with the goal of preventing plantar ulceration.

Purpose: The purpose of this study was to investigate tactile sense perception of the lower extremities according to physical function in children with spastic cerebral palsy. Methods: This study was conducted on 15 children diagnosed with spastic cerebral palsy. Physical function measurement items included dynamic balance ability, gross motor function level, and lower extremity ankle spasticity. The lower extremity tactile sensation uses a monofilament to measure the sole of the first metatarsal head, the sole of the fifth metatarsal head, the heel, the anterior part of the shin midway between the patella and the ankle joint, the kneecap, the upper anterior iliac spine, and the knee. A total of six measurements were taken in the mid-femoral region of the bone. Spearman correlation analysis was performed to determine the degree of body function and lower extremity tactile perception. Results: As the physical function of children with spastic cerebral palsy deteriorated, there was a decrease in tactile sensation in the thigh area corresponding to the proximal lower extremity. (p <.05). Conclusion: Children with spastic cerebral palsy and poor physical function have sensory loss not only in the distal part but also in the proximal part, so a treatment approach that recognizes and improves it is necessary.

Metatarsalgia is one of the most common causes of patients complaining of pain in their feet. This pain is the plantar forefoot, including the second to fourth metatarsal heads and arises from either mechanical or iatrogenic causes. On the other hand, it is frequently accompanied by a deformity of the toes as well as of the first and fifth rays. The pain has a variety of causes, and sometimes the cause is difficult to distinguish. The variability of possible causative factors necessitates an individualized approach to treatment. To determine these causes, this paper presents an overview of the gait mechanics, plantar pressure, and the classification according to the etiology.

Purpose: To determine the locations and incidences of sesamoids and accessory bones of the forefoot in normal Korean adults. Materials and Methods: The plain radiographs of the forefoot of 400 volunteers, 200 males and 200 females, were taken. The three orthopedic surgeons participated in the radiographic evaluation independently. Persons who had history of foot problem or injury were excluded. Results: Sesamoids of first metatarsophalangeal joint were nearly always present; medial 99% and lateral 100%. The bipartite sesamoid was more common in medial (9.8%) and in female (17.0%) than in lateral (0.3%) and in male (2.5%). Sesamoids of the interphalangeal joint of the first toe were seen in 35.8%. Sesamoids of metatarsophalangeal joints in other four toes were rarely observed. Their incidences were 5% in second toe, 0.8% in third, 0% in fourth, and 2.8% (lateral) and 7.5% (medial) in fifth. Sesamoids of interphalangeal joint in four lesser toes were not observed except two cases (0.5%) in the fifth toe. Accessory bone was very rarely observed. Os vesalianum was observed in five feet (1.3%), Os intermetatarseum in 14 feet (3.5%), and Os cuneo-metatarsal I tibiale in none. Conclusion: We determined the location and incidences of sesamoids and accessory bones of the forefoot, and we expected this to help to diagnose the forefoot problem.
