Driving After Hallux Valgus Surgery

Background: The purpose of the study was to determine when patients can safely return to driving after first metatarsal osteotomy for hallux valgus correction. Methods: After institutional review board approval, 60 patients undergoing right first metatarsal osteotomy for hallux valgus correction surgery were recruited prospectively. Patients’ brake reaction time (BRT) was tested at 6 weeks and repeated until patients achieved a passing BRT. A control group of twenty healthy patients was used to establish as passing BRT. Patients were given a novel driver readiness survey to complete. Results: At 6 weeks, 51 of the 60 patients (85%) had BRT less than 0.85 seconds and were considered safe to drive. At 6 weeks, the passing group average was 0.64 seconds. At the 8 weeks, 59 patients (100%) of those who completed the study achieved a passing BRT. Patients that failed at 6 weeks had statistically greater visual analog scale (VAS) pain score and diminished first metatarsophalangeal (MTP) range of motion (ROM). On the novel driver readiness survey, 8 of the 9 patients (89%) who did not pass disagreed or strongly disagreed with the statement, “Based on what I think my braking reaction time is, I think that I am ready to drive.” Conclusion: Most patients may be informed that they can safely return to driving 8 weeks after right metatarsal osteotomy for hallux valgus correction. Some patients may be eligible to return to driving sooner depending on their VAS, first MTP ROM, and driver readiness survey results. Level of Evidence: Level II, comparative study

First Metatarsal

Background: Modified Bösch osteotomy (distal linear metatarsal osteotomy [DLMO]) is one of the minimally invasive correctional surgeries for hallux valgus. The 3-dimensional correctional angles and distances of the first metatarsal bone in DLMO have not been clarified. The purpose of this study was to analyze the 3-dimensional postoperative morphological changes of the first metatarsal bone in DLMO. Methods: Twenty patients (30 feet) who underwent DLMO were enrolled. Preoperative plain radiographs and computed tomography (CT) scans of the feet were examined. Postoperative radiographs and CT scans were also obtained after bone union. The surface data of the pre- and postoperative first metatarsals were reconstructed from the CT data. The positions of the distal ends of the first metatarsals described with respect to the proximal ends were calculated using CT surface-matching technique. Results: The distal end of the first metatarsal after DLMO was significantly supinated (10.2 ± 6.0 degrees, P < .001), adducted (6.0 ± 11.8 degrees, P = .004), dorsiflexed (11.1 ± 10.9, P < .001), shortened (7.4 ± 2.5 mm, P < .001), elevated (2.3 ± 3.1 mm, P = .001), and laterally shifted (8.2 ± 3.0 mm, P < .001) compared to the preoperative metatarsal distal end. Supination correction demonstrated a significant correlation with adduction correction ( r = 0.659, P < .001) on correlation analyses between these parameters. Conclusion: The 3-dimensional corrections of the first metatarsal bone after DLMO were evaluated. Pronation and abduction were successfully corrected. Furthermore, adduction correction might be an important factor affecting correction of pronation. Level of Evidence: Level IV, retrospective case series.

Background: We aimed to compare the postoperative height of the second metatarsal head relative to the first metatarsal head using axial radiographs among 3 different commonly used osteotomy techniques: proximal chevron metatarsal osteotomy (PCMO), scarf osteotomy, and distal chevron metatarsal osteotomy (DCMO). Methods: We retrospectively reviewed the radiographs and clinical findings of the patients with painful callosities under the second metatarsal head, complicated by hallux valgus, who underwent isolated PCMO, scarf osteotomy, or DCMO from February 2005 to January 2015. Each osteotomy was performed with 20 degrees of plantar ward obliquity. Along with lateral translation and rotation of the distal fragment to correct the deformity, lowering of the first metatarsal head was made by virtue of the oblique metatarsal osteotomy. Results: Significant postoperative change in the second metatarsal height was observed on axial radiographs in all groups; this value was greatest in the PCMO group (vs scarf: P = .013; vs DCMO: P = .008) but did not significantly differ between the scarf and DCMO groups ( P = .785). The power for second metatarsal height correction was significantly greater in the PCMO group (vs scarf: P = .0005; vs DCMO: P = .0005) but did not significantly differ between the scarf and DCMO groups ( P = .832). Conclusions: Among the 3 osteotomy techniques commonly used to correct hallux valgus deformity, we observed that PCMO yielded the most effective height change of the second metatarsal head.

Width Reduction

Background: Foot width reduction is a desirable cosmetic and functional outcome for patients with hallux valgus. Triplanar first tarsometatarsal (TMT) arthrodesis could achieve this goal by 3-dimensional correction of the deformity. The aim of this study was to evaluate changes in bony and soft tissue width in patients undergoing triplanar first TMT arthrodesis. Methods: After receiving Institutional Review Board approval, charts were retrospectively reviewed for patients undergoing triplanar first TMT arthrodesis for hallux valgus at 4 institutions between 2016 and 2019. Patients who underwent concomitant first metatarsal head osteotomies (eg, Silver or Chevron) or fifth metatarsal osteotomies were excluded. Preoperative and postoperative anteroposterior weightbearing radiographs were compared to evaluate for changes in bony and soft tissue width. One hundred forty-eight feet from 144 patients (48.1 ± 15.7 years, 92.5% female) met inclusion criteria. Results: Preoperative osseous foot width was 96.2 mm, compared to 85.8 mm postoperatively ( P < .001). Preoperative soft tissue width was 106.6 mm, compared to 99.3 mm postoperatively ( P < .001). Postoperatively, patients had an average 10.4 ± 4.0 mm reduction (10.8% reduction) in osseous width and average 7.3 ± 4.0 mm reduction (6.8% reduction) in soft tissue width. Conclusions: Triplanar first TMT arthrodesis reduced both osseous and soft tissue foot width, providing a desirable cosmetic and functional outcome for patients with hallux valgus. Future studies are needed to determine if patient satisfaction and outcome measures correlate with reductions in foot width. Level of evidence: Level III, retrospective comparative study

Traction Test

Category: Bunion Introduction/Purpose: To investigate the significance of using an intraoperative first metatarsal traction test in hallux valgus correction surgery in decision making of the procedure choice and operation designs. Methods: From Jun 2015 to Jun 2016, correction surgery performed in patients with hallux valgus 40 cases with 68 feet. We used the intra-operative first metatarsal traction test to judge the grade of laxity of the 1st TMT and the factual IMA and thus help to make the decision of the level of osteotomy and or fusion. We adopted distal Chevon osteotomy (11 cases 16.2%) when the congruence of the surface of the 1st MPJ remains more than ½ under tension with the traction test. Proximal Scarf osteotomy (54 cases 79.4%) was used when the congruence was less than ½. While if there was a complete incongruent dislocation, Lapidus procedure (3 cases 4.4%) was carried out. We measured IMA and HVA in the patients preoperative, intraoperative, 3 days after operation and at 6 months’ follow-up. Same measurements were done on the 40 patients from the same time without traction test Results: Retrospective review of the 2 groups showing significant improvement (p<0.001) but more reliable larger correction of IMA angles in the intraoperative traction test group. The patients of the intraoperative traction test group had average higher satisfaction rate with more reliable improvement of symptoms and less postoperative complications. Significant improvement (P<0.001) and postoperative AOFAS score average of 93.2 was recorded in traction test method group vs. a 84.3 in control group. The traction test group largely retained the correction in half year follow up which is significant when comparing to the control Conclusion: The intraoperative traction test of first metatarsal objectively guided the decision making of procedure choice and operation design optimization. The traction test gave a reliable assessment of the laxity of first TMT thus avoiding inadequate correction of Hallux Valgus with improper surgical designs. The test can be potentially used as an objective intraoperative guidance in avoidance of inadequate correction with inappropriate surgical choices and thus maintain the correction in the long term with patient satisfaction

Background: The aim of this study was to assess radiographic and clinical outcomes after double osteotomy with proximal opening wedge first metatarsal osteotomy and first metatarsal distal chevron osteotomy in the treatment of moderate to severe hallux valgus. Methods: 33 patients (4 male, 29 female; 36 feet; average age 60.7 years) were included in the study. Radiographic and clinical outcome in terms of intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), and the American Orthopaedic Foot & Ankle Society metatarsophalangeal-interphalangeal hallux score (AOFAS MTP-IP hallux score) were investigated at 6 weeks, 6 months, and after an average of 28 (range, 7-123) months postoperatively. Results: Preoperative IMA, HVA, and DMMA showed statistically significant improvement ( P ≤ .05) from 19.1 ± 3.8 (8.9-27.3) degrees, 45.4 ± 8.7 (25.9-60.9) degrees, and 20.8 ± 8.9 (4.5-38.0) degrees to 6.0 ± 3.3 (0.4-12.2) degrees, 9.1 ± 8.9 (–6.7 to 39.0) degrees, and 6.4 ± 5.6 (–6.8 to 21.0) degrees at last follow-up, respectively. Postoperative AOFAS MTP-IP hallux score averaged 88.1 points. Overall, 10 complications were observed: hallux varus (3 feet), hallux valgus recurrence (3 feet), nonunion (1 foot), loss of fixation (1 foot), and wound infection (2 feet). Conclusion: Proximal opening wedge first metatarsal osteotomy with distal chevron osteotomy provided powerful correction of each component of moderate to severe hallux valgus but had a substantial rate of complications in terms of over- and undercorrection, nonunion, loss of fixation, and wound infection.

Anatomic Axis

Background: Distal chevron metatarsal osteotomy (DCO) is a common technique to address hallux valgus (HV), which involves coronal translation of the capital fragment resulting in a nonanatomic first metatarsal. The purpose of this study was to evaluate the radiographic effect of the DCO on the anatomic vs the mechanical axis of the first metatarsal. Our hypothesis was that patients undergoing DCO would have improvement in the mechanical metatarsal axis but worsening of the anatomic axis. Methods: This was a retrospective case series of consecutive patients who underwent DCO for HV. The primary outcomes were the change in anatomic first–second intermetatarsal angle (a1-2IMA) vs mechanical first–second intermetatarsal angle (m1-2IMA). Secondary outcomes included the change in hallux valgus angle (HVA) and medial sesamoid position. Results: 40 feet were analyzed with a mean follow-up of 21.2 weeks. The a1-2IMA increased significantly (mean, 4.1 degrees) whereas the m1-2IMA decreased significantly (mean, 4.6 degrees) following DCO. There was a significant improvement in HVA (mean, 12.5 degrees). Medial sesamoid position was improved in 21 feet (52.5%). Patients with no improvement in sesamoid position were found to have a larger increase in a1-2IMA (mean, 4.7 vs 3.5 degrees, P = .03) and less improvement in m1-2IMA (mean, 3.8 vs 5.2 degrees, P = .02) compared to patients with improvement in sesamoid position. Conclusion: Distal chevron osteotomy for HV was associated with worsening of the anatomic axis of the first metatarsal despite improvements in the mechanical metatarsal axis, HVA, and medial sesamoid position. Greater worsening of the anatomic axis was associated with less improvement of sesamoid position. Our findings may suggest the presence of intermetatarsal instability, which could limit the power of DCO in HV correction for more severe deformities and provide a mechanism for HV recurrence. Level of Evidence: Level IV, retrospective case series.

Akin Osteotomy

Background: The premise of this study was that after the correction of hallux-metatarsophalangeal pronation, the intraoperative interphalangeal angle (HIA) increases significantly, and that an additional Akin osteotomy (AO) is often needed. Therefore, the purpose of this study was to evaluate whether HIAs in hallux valgus (HV) feet were underestimated, and to assess the need for AO during HV correction. Method: This study was conducted on 54 feet with moderate to severe HV treated from June 2007 to December 2008. HIAs and medial sesamoid subluxations (MSS) were measured initially and intraoperatively after a distal soft tissue procedure (DSTP) and proximal chevron metatarsal osteotomy (PCMO). An intraoperative technique was used to evaluate the incongruency of the metatarsophalangeal joint (MTPJ) to determine the need for additional Akin osteotomy. Results: After performing DSTP and PCMO, HIAs significantly increased from an average of 9 to 13.3 degrees and MSS reduced from average grade 2.5 to 0.5 ( p < 0.05). Akin ostetomy was added in 44 (81%) feet. After an average followup of 13.2 months in Akin group, average VAS pain score decreased from 5.7 to 1.2 and average AOFAS score increased from 57.8 to 90.2 ( p < 0.05). Final hallux MTPJ dorsiflexion in the Akin group was significantly larger than in the without-Akin group ( p < 0.05). Conclusion: Average HIA significantly increased after DSTP and PCMO for moderate to severe HV necessitating additional Akin osteotomy, to achieve ideal HV correction and, to preserve MTPJ motion.

Biplanar Radiographs

Rotation of the first metatarsal (M1) as a potential etiological factor of hallux valgus (HV) deformity was described relatively early in the description of HV pathoanatomy. However, because biplanar radiographs have been the standard method for imaging HV, clinicians primarily developed measurement methods and corrective operations confined to 2 dimensions, medial-lateral and inferior-superior. Recently, as our understanding of HV pathoanatomy has further developed, aided in part by advanced imaging technology, M1 rotation about its axis (“axial rotation”) and its implications for HV deformity and treatment has reemerged. The goal of this review is to summarize M1 rotation in HV from a historical perspective, to present the current understanding of its potential role in the etiology/pathogenesis of HV, and to summarize relevant imaging and operative considerations with respect to M1 rotation.

Background: There is no consensus in the foot and ankle literature regarding how to measure pronation of the first metatarsal in patients with hallux valgus. The primary purpose of this study was to compare 2 previously published methods for measuring pronation of the first metatarsal and a novel 3-dimensional measurement of pronation to determine if different measurements of pronation are associated with each other. Methods: Thirty patients who underwent a modified Lapidus procedure for their hallux valgus deformity were included in this study. Pronation of the first metatarsal was measured on weightbearing computed tomography (WBCT) scans using the α angle with reference to the floor, a 3-dimensional computer-aided design (3D CAD) calculation with reference to the second metatarsal, and a novel method, called the triplanar angle of pronation (TAP), that included references to both the floor (floor TAP) and base of the second metatarsal (second TAP). Pearson’s correlation coefficients were used to determine if the 3 calculated angles of pronation correlated to each other. Results: Preoperative and postoperative α angle and 3D CAD had no correlation with each other ( r = 0.094, P = .626 and r = 0.076, P = .694, respectively). Preoperative and postoperative second TAP and 3D CAD also had no correlation ( r = 0.095, P = .624 and r = 0.320, P = .09, respectively). However, preoperative and postoperative floor TAP and α angle were found to have moderate correlations ( r = 0.595, P = .001 and r = 0.501, P = .005, respectively). Conclusion: The calculation of first metatarsal pronation is affected by the reference and technique used, and further work is needed to establish a consistent measurement for the foot and ankle community.

Radiographic Alignment

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.
