The purpose of the study was to compare the range of motion, perceived pain and plantar loading characteristics of the Chevron (Austin) corrective procedures in treating hallux valgus (HV) 12 months postsurgically. Twenty-five female participants with the diagnosis of mild to moderate HV deformity were studied. All participants had a distal metatarsal osteotomy (Chevron (Austin)) to correct their deformity. First metatarsophalangeal and talocrural joint range of motion (ROM) and a 10-point analog pain scale were measured presurgically and 12 months post-surgically on each participant. Radiographic measures of hallux valgus and intermetatarsal (IM) angles were taken preoperatively and six weeks postoperatively for comparison. Five pressure distribution measurements were recorded of barefoot walking using the EMED-SF presurgically and 12 months postsurgically. Statistical analyses revealed that plantar loading is still altered 12 months postsurgically despite a decrease in perceived pain and adequate first metatarsophalangeal joint ROM. Greater loading occurred in the central forefoot (CFF) region with decreases in some of the loading parameters in the medial toe (MT) region postsurgically. Loading parameters in the lateral forefoot (LFF), heel (HL), midfoot (MF), and lateral toe (LT) were unchanged 12 months postsurgery compared to presurgery.

We present the short-term follow-up of 55 symptomatic hallux valgus deformities in 38 patients, treated operatively with a modification of the spike distal first metatarsal osteotomy, as described by Gibson and Piggott in 1962. The age range of the patients was 17 to 72 years at the time of surgery. The postoperative follow-up period was 12 to 55 months. Excellent and good clinical and radiographic results were recorded in 96.2% of our patients. Two of the patients (3.8%) were dissatisfied; one of them complained of metatarsalgia after the procedure, and the other had stiffness of the metatarsophalangeal joint and metatarsalgia that had been present before surgery. Three others (5.45%) required revision after early postoperative displacement but were asymptomatic subsequently. We concluded that our technique is an effective method of treating mild hallux valgus deformities with the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal tilting of the distal fragment. Hallux valgus (lateral deviation of the great toe) is not a single disorder, as the name implies, but a complex deformity of the first ray that sometimes may involve the lesser toes. More than 130 procedures exist for the surgical correction of hallux valgus, which means that no treatment is unique. No single operation is effective for all bunions. 5 , 22 , 29 The objectives of surgical treatment are to reduce pain, to restore articular congruency, and to narrow the forefoot without impairing function, by transferring weight to the lesser metatarsals either by shortening or by dorsal tilting of the first metatarsal. 5 , 19 , 24 , 27 Patient selection is important for a satisfactory outcome after surgery of any kind, and our criteria were age, degree of deformity, presence of arthrosis, and subluxation of the first metatarsophalangeal joint. 1 , 5 , 13 , 19 – 21 , 24 , 29 In this study, we present a new method of treating hallux valgus that has been used at Mayday University Hospital since 1990. The technique was first described at the British Orthopaedic Foot Surgery Society, Liverpool, November 1990, 7 and we now present the short-term follow-up results. The procedure is essentially a modification of the spike osteotomy of the neck of the first metatarsal, as described by Gibson and Piggott. 9 It has the advantages of simplicity, no shortening of the first metatarsal, and no risk of dorsal displacement of the distal fragment.

ABSTRACT Objective: This is a descriptive study to report our method of operative correction for patients with hallux valgus deformities. Methods: From 2006 to 2012, 516 consecutive patients (601 feet) with hallux valgus deformities were treated surgically in our department after conservative treatments were exhausted. The hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle, and degree of osteoarthritis in the first metatarsophalangeal joint were measured on preoperative plain radiographs of the weight-bearing forefoot. Results: Young patients with severe intermetatarsal deviation received a combined proximal and distal osteotomy of the first metatarsal (n = 21). Patients with low intermetatarsal deviation received a distal metatarsal chevron osteotomy (n = 196), whereas patients with severe intermetatarsal deviation and less flexible deformities without osteoarthritis received a basal metatarsal osteotomy with a distal soft tissue procedure (n = 173). Elderly active patients with osteoarthritis in the first metatarsophalangeal joint received an arthrodesis (n = 100) or resection arthroplasty (n = 58). Conclusion: Determining a few simple angles on plain radiographs of the weight-bearing forefoot in combination with the age and level of activity of patients can help simplify the operative correction method by using the schema we developed. Level of evidence IV, case series.

The low-Dye strap is used routinely to temporarily control pronation of the foot and, thereby, to diagnose and treat pronatory sequelae. However, the exact biomechanical effects of this strapping technique on the foot are not well documented. The main purpose of this study was to establish the specific mechanical effects of the low-Dye strap on the pronatory foot. Within this context, the specific aim was to assess the effect of the low-Dye strap on three distinct pronation-sensitive mechanical attributes of the foot in the weightbearing state: 1) calcaneal eversion, 2) first metatarsophalangeal joint range of motion, and 3) medial longitudinal arch height. Weightbearing measurements of these three attributes were made before and after application of a low-Dye strap, and statistical comparisons were made. The results of this study indicate that the low-Dye strap is effective in reducing calcaneal eversion, increasing first metatarsophalangeal joint range of motion, and increasing medial longitudinal arch height in the weightbearing state. Knowledge of the exact mechanisms of action of the low-Dye strap will provide practitioners with greater confidence in the use of this modality. (J Am Podiatr Med Assoc 93(2): 118-123, 2003)

Abstract Background Osteoarthritis of the first metatarsophalangeal joint (1st MTP joint OA) is a common and disabling condition that results in pain and limited joint range of motion. There is inconsistent evidence regarding the relationship between clinical measurement of 1st MTP joint maximum dorsiflexion and dynamic function of the joint during level walking. Therefore, the aim of this study was to examine the association between passive non-weightbearing (NWB) 1st MTP joint maximum dorsiflexion and sagittal plane kinematics in individuals with radiographically confirmed 1st MTP joint OA. Methods Forty-eight individuals with radiographically confirmed 1st MTP joint OA (24 males and 24 females; mean age 57.8 years, standard deviation 10.5) underwent clinical measurement of passive NWB 1st MTP joint maximum dorsiflexion and gait analysis during level walking using a 10-camera infrared Vicon motion analysis system. Sagittal plane kinematics of the 1st MTP, ankle, knee, and hip joints were calculated. Associations between passive NWB 1st MTP joint maximum dorsiflexion and kinematic variables were explored using Pearson’s r correlation coefficients. Results Passive NWB 1st MTP joint maximum dorsiflexion was significantly associated with maximum 1st MTPJ dorsiflexion (r=0.486, p<0.001), ankle joint maximum plantarflexion (r=0.383, p=0.007), and ankle joint excursion (r=0.399, p=0.005) during gait. There were no significant associations between passive NWB 1st MTP joint maximum dorsiflexion and sagittal plane kinematics of the knee or hip joints. Conclusions Passive NWB 1st MTP joint maximum dorsiflexion is associated with sagittal plane kinematics of the 1st MTP and ankle joints during level walking in individuals with 1st MTP joint OA. These findings suggest that clinical measurement of 1st MTP joint maximum dorsiflexion provides useful insights into the dynamic function of the foot and ankle during the propulsive phase of gait in this population.

To assess the repeatability and error of conventional x-ray measurements, intra- and interobserver evaluations of measurement accuracy were done on 20 preoperative and 40 postoperative (20 chevron and 20 proximal osteotomy) x-rays of hallux valgus patients. Standard x-rays showed an average interobserver error of measurement of 6.4° for the hallux valgus angle, 5.4° for the intermetatarsal angle, and 2.0 mm for the intermetatarsal distance. The intraobserver error did not differ greatly. The repeatability and error of two clinical measurements, ball circumference, and dorsal to plantar range of motion of the first metatarsophalangeal joint were evaluated for 20 healthy volunteers. The ball circumference had an average measurement error of 1.1 cm, whereas the dorsal and plantar range of motion of the great toe had an average measurement error of 12° in dorsiflexion and 16° in plantarflexion. In both clinical and radiographic parameters, linear measurements were more accurate than angular measurements. Although x-rays are of value in hallux valgus surgery, standard x-rays are less accurate than previously assumed. Small changes produced by osteotomies may be hidden by the postoperative measurement error. The results of hallux valgus surgery should primarily be evaluated clinically. When clinical and radiological evaluations are made, linear measurements may be preferable.

The purpose of the present study is to illustrate the use of a modified subcapital metatarsal osteotomy (MSMO) in the treatment of hallux valgus (HV) recurrence. The article reports the clinical and radiological outcomes of a cohort of 52 consecutive patients presenting with recurrent HV, treated with MSMO. A total of 52 patients (54 feet) underwent operations between May 2010 and November 2015. The mean time of follow-up was 2.5 years (range 5.5-1.0 years), and the mean age was 49 years (range 22-76 years). The patient cohort comprised 46 female and 6 male patients. The results of this research show that MSMO is a reliable technique for the correction of HV recurrence. The postoperative radiographic assessments show a statistically significant postoperative improvement of the HV angle (P < .05) and the intermetatarsal angle (P < .05). The postoperative position of the tibial sesamoid was significantly improved (P < .1). The distal metatarsal articular angle was improved (P < .001), though assessment may be affected by the previous operations performed on the first metatarsophalangeal joint. The statistical analysis shows that the postoperative American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale parameters were significantly improved (P < 0.001). Results of this study indicate that the minimally invasive MSMO is effective in restoring anatomical alignment and improving patient outcomes in recurrent cases of HV.

Background: We investigated the relationship between functional and static foot posture and medial tibial stress syndrome in distance runners. Methods: Twenty-eight runners with a clinical diagnosis of medial tibial stress syndrome and 12 asymptomatic runners were assessed with the Foot Posture Index to measure static overpronation. Range of motion was measured at the talocrural joint, with the knee extended and flexed as was range of motion at the first metatarsophalangeal joint and the angular difference between the neutral and relaxed calcaneal stance positions. Each participant was then videotaped while running on a treadmill shod and unshod. This videotape was analyzed using freeze frame to identify abnormal or mistimed pronation at each phase of gait. The results were analyzed using logistic regression to give the probability that a runner is likely to experience medial tibial stress syndrome, predicted from the static measurements and dynamic observations. Results: Variables identified as being significant predictors of medial tibial stress syndrome were the difference between the neutral and relaxed calcaneal stance positions, range of motion of the talocrural joint with the knee extended, early heel lift and abductory twist during gait, and apropulsive gait. Conclusion: Runners with suspected symptoms of medial tibial stress syndrome should be assessed dynamically and statically for abnormal or mistimed pronation.
