Purpose: To statistically evaluate the contributing role of the 3 radiographic factors (Obliquity, Asymmetry, Joint deviation) of the hallux valgus interphalangeus with comparison to the normal control group. Materials and Methods: The study is based on the standing foot AP radiographs of the 77 feet (56 patients) of the hallux valgus interphalangeus out of 119 feet of randomly sampled patients of the age range 20 to 60. Fractures or other foot disorders have been excluded. Obliquity, asymmetry and joint deviation factors formed by proximal and distal phalanges of hallux are measured by one observer and evaluated the statistical significance of the contribution of the 3 factors to the hallux interphalangeal angle (HIA). Results: The average age of the patients were 36.0 years old and average HIA was $14.5^{\circ}{\pm}2.8^{\circ}$. Obliquity was measured $4.8^{\circ}{\pm}2.90^{\circ}$, asymmetry $8.2^{\circ}{\pm}3.28^{\circ}$ and joint deviation $2.0^{\circ}{\pm}1.85^{\circ}$. All 3 factors showed the statistical significance as the contributing factors to the HIA and among them, the asymmetry played the biggest role (p<0.05). Conclusion: Hallux interphalangeal angle is formed by 3 radiographic factors (Obliquity, Asymmetry, Joint deviation), and among them the asymmetry factor plays the biggest role.

Purpose: The purpose of this study is comparison of radiological and clinical outcomes between proximal metatarsal osteotomy and distal chevron osteotomy for the correction of hallux valgus. Materials and Methods: In this retrospective study, we included subjects who underwent the correction of hallux valgus in our institution between March 2001 and August 2006, with a minimum follow-up of 12 months. The group of proximal metatarsal osteotomy was 23 patients (34 feet); the group of distal chevron osteotomy was 20 patients (26 feet). The group of proximal metatarsal osteotomy was composed of 26 severe cases (76.5%) and 8 moderate cases (23.5%); the group of distal chevron osteotomy was composed of 13 severe cases (50.0%) and 13 moderate cases (50.0%). Results: Compared to preoperative values, the hallux valgus angle, the first-second intermetatarsal angle and the distance of first-fifth metatarsal head were significantly decreased in two groups (p<0.05). In each parameter, the hallux valgus angle was decreased 66.3% (proximal metatarsal osteotomy) versus 49.6% (distal chevron osteotomy), which were significant (p=0.037). The first-second intermetatarsal angle and the distance of first-fifth metatarsal head were not significant. Mayo clinic forefoot scoring system (FFSS) score was significantly improved in two groups (p<0.05). The ratio of improvement was not significant (p=0.762). In severe group, hallux valgus angle and the first-second intermetatarsal angle was significantly decreased in proximal metatarsal osteotomy group compared to distal chevron osteotomy group (p<0.05), but the difference of the distance of first-fifth metatarsal head and FFSS score was not significant in both groups. In moderate group, the difference of all parameters was not significant in both groups. Conclusion: Although both proximal metatarsal osteotomy and distal chevron osteotomy showed satisfactory result in FFSS, proximal metatarsal osteotomy was more proper operative technique than distal chevron osteotomy in severe group, because of superiority of correction in radiological parameters.

Purpose: The purpose of this study is to evaluate the effect of axial shortening metatarsal osteotomy on the treatment of advanced rheumatoid arthritis patients with severe hallux valgus and claw toe deformity of lesser toes which is used for preserving the metatarsophalangeal joint. Materials and Methods: From January 2005 to June 2009, 18 cases of axial shortening metatarsal osteotomy in advanced rheumatoid arthritis were reviewed ; all of them followed up for more than 2 years after surgical procedures and the mean follow up period was 3.4 years. We performed axial shortening Scarf osteotomy and Akin osteotomy for hallux valgus and Weil osteotomy with soft tissue release for claw toe of lesser toes, respectively. We measured preoperative and postoperative hallux valgus angle, each metatarsal shortening length and the range of motion of the metatarsophalangeal joints through radiographic and clinical examination and compared them each other. Clinical results were evaluated by American Orthopedic Foot and Ankle Society (AOFAS) score and subjective satisfaction of the patients. Results: The hallux valgus angle was reduced from the preoperative mean value of 44.8 degree to 9.0 degree postoperatively and the range of motion of the metatarsophalangeal joint of great toe and lesser toes was increased from the mean of 21.7 degree and 11.0 degree preoperatively to 38.0 degree and 32.5 degree, respectively at postoperation. Also, the mean AOFAS score was improved from 26.5 points to 67.4 points. Conclusion: Axial shortening osteotomy is a useful method to correct the deformity and preserve the metatarsophalangeal joint for severe hallux valgus and claw toe deformity in advanced rheumatoid arthritis.

Purpose: This study compared the results of proximal and distal chevron osteotomy in patients with severe hallux valgus. Several recent studies have shown that the indications for distal metatarsal osteotomy with a distal soft-tissue procedure could be extended to include severe hallux valgus. Materials and Methods: This study analyzed 127 severe hallux valgus surgeries. Of these, 76 patients (76 feet) were excluded for lack of adequate follow-up and additional procedures (Akin procedure), leaving 51 patients (51 feet) in the study. The mean age of the patients was 58 years (21~83 years), and the mean follow-up duration was 18 months (12~32 months). The patients were divided into two groups. Group 1 underwent distal chevron osteotomy, and group 2 underwent proximal chevron osteotomy performed sequentially by a single surgeon. The patients were interviewed for the American Orthopaedic Foot and Ankle Society (AOFAS) score before and one year after surgery. The anteroposterior weight-bearing radiography of the foot was taken before and one year after surgery. Results: There were no significant differences in pain and function after one year in either group. Both groups experienced significant pain reduction and an increase in the AOFAS score. Significant improvement of the hallux valgus and intermetatarsal angle corrections was observed in both groups, and the sesamoid position was similar in each group. More improvement in radiographic correction of intermetatarsal angle was noted in group 2. Both procedures gave similar good clinical and radiological outcomes. Conclusion: This study suggests that a distal chevron osteotomy with a distal soft-tissue procedure is as effective and reliable a means of correcting severe hallux valgus as a proximal chevron osteotomy with a distal soft-tissue procedure.

In a retrospective study, we compared the results of 24 cases of Chevron osteotomies with those of 17cases of Wilsons osteotomies in the treatment of hallux valgus. We used FFSS(Fore Foot Scoring System) and radiographic findings. There were no differences between the two operations in terms of pain relief and appearance. All patients in the Chevron and Wilsons osteotomy group had good functional results and were more satisfied with the appearance of the foot. We conclude Wilsons osteotomy is useful method for correction of hallux valgus.

The purpose of this study was to evaluate the effect of joint mobilization and manual stretching exercises in patients with hallux valgus. Twenty-three participants were divided into two groups; joint mobilization (n=11) and manual stretching exercises (n=12). The subjects participated in the experiment for 15minutes, three times a week, four weeks. The joint mobilization (Grade III, Maitland) was performed to experimental group for a minute and then rested for 10 seconds for each set. The manual stretching was performed to control group with three exercise session (preparatory and finishing exercises, agonist contraction exercises, agonist contraction and hold-relax exercises). In the results of the study, intragroup comparison of the deformity angles (DA) was shown to decrease from $15.18^{\circ}$ to $13.09^{\circ}$ in the joint mobilization group (p<.05) and from $19.00^{\circ}$ to $16.83^{\circ}$ in the stretching exercises group (p<.05). However, left static foot pressure (LSFP), right static foot pressure (RSFP), left dynamic foot pressure (LDFP) and right dynamic foot pressure (RDFP) did not significantly increase or decrease after the experiment. Intergroup differences also were not statistically significant in all variables (p>.05). The current study suggests that JM and MSE are effective in decreasing the DA in patients with hallux valgus.

PURPOSE: This study examined the relationship between the severity of a hallux valgus (HV) deformity and the kinetic three-dimensional ground reaction force (GRF) through a motion analysis system with force platforms in individuals with a HV deformity during normal speed walking. METHODS: The participants were 36 adults with a HV deformity. The participants were asked to walk on a 6 m walkway with 40 infrared reflective markers attached to their pelvic and lower extremities. A camera capture system and two force platforms were used to collect kinetic data during gait. A Vicon Nexus and Visual3D motion analysis software were used to calculate the kinetic GRF data. RESULTS: This research showed that the anterior maximal force that occurred in the terminal stance phase during gait had a negative correlation with the HV angle (r = -.762, p < .01). In addition, the HV angle showed a low negative correlation with the second vertical maximal force (r = .346, p < .05) and a moderate positive correlation with the late medial maximal force (r = .641, p < .01). CONCLUSION: A more severe HV deformity results in greater abnormal translation of the plantar pressure and a significantly reduced pressure force under the first metatarsophalangeal joint.
