Interobserver Error

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.

Objective: Sesamoid displacement (SD) and rotation are important components in the preoperative assessment of hallux valgus (HV). To date, Inter reader reliability (IRR) of SD on X-rays and MRI, correlations with hallux valgus angle (HVA), and qualitative changes of the hallux-sesamoid complex (HSC) on MRI have not been studied. The aim of this study was to correlate sesamoid malalignment with HV severity and findings of internal joint derangement. Methods: Two readers analyzed a series of 56 consecutive patients who had X-rays and MRI performed on the same foot within 3 months of each other. Multiple measures of SD on X-rays and MRI and the sesamoid rotation angle (SRA) on MRI were assessed and correlated with HVA and various qualitative features at the HSC including cartilage, plantar plate, and collateral ligament abnormalities. Results: We found excellent IRR (ICC = 0.79 – 0.99) for SRA on MR, but poor IRR for lateral sesamoid displacement (LDS) and tibial sesamoid position (TSP) scales on both modalities. Good IRR was also seen for morphologic abnormalities of HSC. The absolute value of the SRA on MR positively correlated with HVA ( p < 0.0001). LDS and TSP on both modalities lacked a significant correlation with HVA ( p > 0.05). No correlation was found between any measure of SD or rotation with HSC morphologic changes ( p > 0.05). Conclusion: Among different measures of sesamoid malalignment, sesamoid rotation angle measured on MRI can be used to judge the severity of HV; however, it does not correlate with qualitative morphologic abnormalities of the HSC. Advances in knowledge: The MRI measurement of SRA is a better indicator of sesamoid displacement relative to the HSC than standard AP radiographic measures of non-rotational sesamoid displacement; however, it should not be used to predict qualitative morphologic abnormalities of the HSC.

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.

First Metatarsophalangeal Joint

Background: Capsulorrhaphy restricts the motion of the first metatarsophalangeal joint (MTPJ) in hallux valgus surgery. However, changes in motion of the first MTPJ immediately after surgery that resulted from different capsulorrhaphy methods have not been compared. The primary aim of this study was to compare the immediate effect of Y-shaped and inverted L capsulorrhaphy methods on the range of motion (ROM) of the first MTPJ. Methods: Y-shaped and inverted L capsulorrhaphies were performed on 16 human cadaveric feet. Passive dorsiflexion and plantarflexion of the first MTPJ were then compared preoperatively and postoperatively. Results: In this cadaveric study, the inverted L capsulorrhaphy method led to a ROM loss in the first MTPJ; the joint stiffness from the Y-shaped capsulorrhaphy is significantly less than that from the inverted L capsulorrhaphy. Conclusions: The inverted L capsulorrhaphy may lead to a ROM loss in the first MTPJ immediately after surgery. We recommend that surgeons close the capsule of the first MTPJ with a Y-shaped capsulorrhaphy, which is less likely to result in a ROM loss in the first MTPJ in the early postoperative period.

Bone Structures

Hallux valgus is characterized by the appearance and growth of a painful “lump” in the region of the first metatarsophalangeal joint, the development of forefoot corns, and inability to choose the right shoes, which leads to a significant decrease in the quality of life of these patients. Corrective osteotomies that preserve the metatarsophalangeal joint, for example Austin (Chevron) osteotomy, are usually used for hallux valgus deformity of the I, II degrees. Radiography with the study of the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMAA) is a research method that shows the true correlation between bone structures. The correlation between the radiological and functional indicators of osteotomy allows us to determine possible recommendations for indications for surgical treatment of Hallux valgus. Correlation shows that the largest correction of hallux valgus in older patients occurs due to a small adjustment of the angle of DMMA and HVA. IMA had the best correction after Austin osteotomy among patients of a younger age, then the HVA, and the DMMA had minimum correction according to the AOFAS rating scale (Kitaoka). The revealed correlations allow us to determine the correct tactics for the treatment of hallux valgus by identifying the benefits of Austin osteotomy.

Correction osteotomies of the first metatarsal are common surgical approaches in treating hallux valgus deformities whereas the Scarf osteotomy has gained popularity. The purpose of this study was to analyze short- and mid-term results in hallux valgus patients who underwent a Scarf osteotomy. The subjective and radiological outcome of 131 Scarf osteotomies (106 hallux valgus patients, mean age: 57.5 years, range: 22-90 years) were retrospectively analyzed. Mean follow-up was 22.4 months (range: 6 months-5 years). Surgical indications were: intermetatarsal angle (IMA) of 12-23&deg;; increased proximal articular angle (PAA&gt;8&deg;), and range of motion of the metatarsophalangeal joint in flexion and extension &gt;40&deg;. Exclusion criteria were severe osteoporosis and/or osteoarthritis. The mean subjective range of motion (ROM) of the great toe post-surgery was 0.8&plusmn;1.73 points (0: full ROM, 10: total stiffness). The mean subjective cosmetic result was 2.7&plusmn;2.7 points (0: excellent, 10: poor). The overall post-operative patient satisfaction with the result was high (2.1&plusmn;2.5 points (0: excellent, 10: poor). The mean hallux valgus angle improvement was 16.6&deg; (pre-operative mean value: 37.5&deg;) which was statistically significant (p&lt;0.01). The IMA improved by an average of 5.96&deg; from a pre-operative mean value of 15.4&deg; (p&lt;0.01). Neither osteonecrosis of the distal fragment nor peri-operative fractures were noted during the follow-up. In keeping with our follow-up results, the Scarf osteotomy approach shows potential in the therapy of hallux valgus. 筻

The Austin osteotomy is a widely accepted method for correction of mild and moderate hallux valgus. In view of publications by Kitaoka et al. in 1991 and by Mann and colleagues, a more radical lateral soft tissue procedure was added to the originally described procedure. From September 1992 to January 1994, 85 patients underwent an Austin osteotomy combined with a lateral soft tissue procedure to correct their hallux valgus deformities. Seventy-nine patients (94 feet) were available for follow-up. The average patient age at the time of the operation was 47.1 years, and the average follow-up was 16.2 months. The average preoperative intermetatarsal angle was 13.9°, and the average hallux valgus angle was 29.7°. After surgery, the feet were corrected to an average intermetatarsal angle of 5.8° and an average hallux valgus angle of 11.9°. Sesamoid position was corrected from 2.1 before surgery to 0.5 after surgery. The results were also graded according to the Hallux Metatarsophalangeal Interphalangeal Score, and the functional and cosmetic outcomes were graded by the patient. Dissection of the plantar transverse ligament and release of the lateral capsule repositioned the tibial sesamoid and restored the biomechanics around the first metatarsophalangeal joint. There was no increased incidence of avascular necrosis of the first metatarsal head compared with the original technique.

Background: Instability of the first-tarsometatarsal (TMT) joint has been proposed as a cause of hallux valgus. Although there is literature demonstrating how first-TMT arthrodesis affects hallux valgus, there is little published on how correction of hallux valgus affects the first-TMT joint alignment. The purpose of this study was to determine if correction of hallux valgus impacts the first-TMT alignment and congruency. Improvement in alignment would provide evidence that hallux valgus contributes to first-TMT instability. Our hypothesis was that correcting hallux valgus angle (HVA) would have no effect on the first-TMT alignment and congruency. Methods: Radiographs of patients who underwent first-MTP joint arthrodesis for hallux valgus were retrospectively reviewed. The HVA, 1-2 intermetatarsal angle (IMA), first metatarsal–medial cuneiform angle (1MCA), medial cuneiform–first metatarsal angle (MC1A), relative cuneiform slope (RCS), and distal medial cuneiform angle (DMCA) were measured and recorded for all patients preoperatively and postoperatively. Results: Of the 76 feet that met inclusion criteria, radiographic improvements were noted in HVA (23.6 degrees, P < .0001), 1-2 IMA (6.2 degrees, P < .0001), 1MCA (6.4 degrees, P < .0001), MC1A (6.5 degrees, P < .0001), and RCS (3.3 degrees, P = .001) comparing preoperative and postoperative radiographs. There was no difference noted with DMCA measurements (0.5 degrees, P = .53). Conclusion: Our findings indicate that the radiographic alignment and subluxation of the first-TMT joint will reduce with isolated treatment of the first-MTP joint. Evidence suggests that change in the HVA can affect radiographic alignment and subluxation of the first-TMT joint. Level of Evidence: Level IV, retrospective case series.
