Correlation of Preoperative Radiographic Severity With Disability and Symptom Severity in Hallux Valgus

Background: Some US insurance companies have recently started to require minimum angular measurements, for coverage decisions, in patients seeking operative correction for symptomatic hallux valgus. This logic naturally assumes that the magnitude of radiographic bunion deformity is related to the magnitude of patient’s presenting symptoms and/or disability. Methods: We conducted an analysis of existing data in our practice to determine whether patient-reported symptoms and disability prior to bunion surgery correlated with preoperative radiographic measurements commonly used to quantify hallux valgus severity. Symptoms and disability level were determined using patient-reported preoperative Foot and Ankle Outcome Score (FAOS), a validated instrument commonly used in hallux valgus assessment. Spearman correlation coefficient was then used to quantify the strength of any correlations. Preoperative data from 107 patients (107 feet) with mean age of 49.3 ± 13.8 years who underwent isolated osseous hallux valgus surgery within our practice between June 1, 2016, and July 30, 2018, were available. Results: No radiographic variable achieved even a moderate correlation with any of the FAOS subscales with the exception of tibial sesamoid position with FAOS Pain (rho=0.402, P = .01) in patients aged 56 years and older. The direction of this correlation was positive, indicating that greater preoperative sesamoid abnormalities were paradoxically associated with less presenting pain (ie, higher FAOS Pain scores). Conclusion: It would appear that radiographic severity of bunion deformity is not well correlated with symptom level and/or disability and, we would argue, should not play a role in coverage decisions for patients presenting for hallux valgus surgery.

Background: The modified Lapidus is a surgical procedure for managing moderate to severe hallux valgus, especially in the presence of first tarsometatarsal joint arthritis or hypermobility. It has good long-term results but reportedly can lead to transfer metatarsalgia due to inherent shortening of the first metatarsal. Methods: A retrospective analysis of all adult patients who underwent a modified Lapidus procedure during a 3-year period was performed. Clinical notes were evaluated to look for nonunion or any other complications related to the surgery. Pre- and postoperative standard weightbearing radiographs were used to establish the relative metatarsal length (RML), intermetatarsal angle (IMA), hallux valgus angle (HVA), and distal metatarsal articular angle (DMMA). A total of 69 modified Lapidus procedures were identified, with 32 included in the study. Results: The mean pre- and postoperative RMLs were −0.8 and −4.9 mm, respectively. The average RML shortening due to the procedure was −4.1 ( P < .0001). The mean pre- and postoperative IMAs were 15 and 5 degrees, respectively ( P < .0001). The mean pre- and postoperative HVAs were 33 and 9 degrees, respectively ( P < .0001). One patient reported transfer metatarsalgia, which was attributed to elevation of the first metatarsal. Conclusion: We found a statistically significant degree of shortening of the relative length of the first metatarsal without any clinically significant metatarsalgia. The low rate of transfer metatarsalgia following the modified Lapidus procedure could be attributed to the sagittal plane correction and stability obtained by performing a first tarsometatarsal fusion.

Background: Supination-adduction (SAD) type II ankle fractures can have medial tibial plafond and talar body impaction. Factors associated with the development of posttraumatic arthritis can be intrinsic to the injury pattern or mitigated by the surgeon. We hypothesize that plafond malreducton and talar body impaction is associated with early posttraumatic arthrosis. Methods: A retrospective cohort of skeletally mature patients with SAD ankle fractures at 2 level 1 academic trauma centers who underwent operative fixation were identified. Patients with a minimum of 1-year follow-up were included. The presence of articular impaction identified on CT scan was recorded and the quality of reduction on final intraoperative radiographs was assessed. The primary outcome was radiographic ankle arthrosis (Kellgren-Lawrence 3 or 4), and postoperative complications were documented. Results: A total of 175 SAD ankle fractures were identified during a 10-year period; 79 patients with 1-year follow-up met inclusion criteria. The majority of injuries resulted from a high-energy mechanism. Articular impaction was present in 73% of injuries, and 23% of all patients had radiographic arthrosis (Kellgren-Lawrence 3 or 4) at final follow-up. Articular malreduction, defined by either a gap or step >2 mm, was significantly associated with development of arthrosis. Early treatment failure, infection, and nonunion was rare in this series. Conclusion: Malreduction of articular impaction in SAD ankle fractures is associated with early posttraumatic arthrosis. Recognition and anatomic restoration with stable fixation of articular impaction appears to mitigate risk of posttraumatic arthrosis. Investigations correlating postoperative and long-term radiographic findings to patient-reported outcomes after operative treatment of SAD ankle fractures are warranted.

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.

Background: Recurrence is relatively common after surgical correction of hallux valgus. Multiple factors are discussed that could have an influence in the loss of correction. The aim of this study was to determine preoperative radiological factors with an influence on loss of correction after distal chevron osteotomy for hallux valgus. Methods: Five hundred twenty-four patients who underwent the correction of a hallux valgus by means of distal chevron osteotomy at our institution between 2002 and 2012 were included. We assessed weightbearing x-rays at 4 time points: preoperatively, postoperatively, and after 6 weeks and 3 months. We investigated the intermetatarsal angle (IMA), the hallux valgus angle (HVA), the distal metatarsal articular angle (DMAA), joint congruity, and the position of the sesamoids. Results: At all points of the survey, significant correction of the IMA and HVA was detected. The IMA improved from 12.9 (± 2.8) to 4.5 (± 2.4) degrees and the HVA from 27.5 (± 6.9) to 9.1 (± 5.3) degrees. Loss of correction was found in both HVA and IMA during follow-up with a mean of 4.5 and 1.9 degrees, respectively. Loss of correction showed a linear correlation with preoperative IMA and HVA, and a correlation between preoperative DMAA and sesamoid position. Conclusion: The chevron osteotomy showed significant correction for HVA, IMA, and DMAA. Preoperative deformity, in terms of IMA, HVA, DMAA, and sesamoid position, correlated with the loss of correction and could be assessed preoperatively for HVA and IMA. Loss of correction at 3 months persisted during the follow-up period. Level of Evidence: Level IV, retrospective case series.

Category: Bunion Introduction/Purpose: Minimally invasive surgery for hallux valgus has significantly increased in popularity recently due to smaller incisions, reduced soft tissue trauma, and the ability to achieve large deformity corrections compared to traditional treatments. This study aimed to investigate the radiological outcomes and degree of deformity correction of the intermetatarsal angle (IMA) and the hallux valgus angle (HVA) following third generation (using screw fixation) Minimally Invasive Chevron and Akin Osteotomies (MICA) for hallux valgus. Methods: A single surgeon case series of patients with hallux valgus underwent primary, third generation MICA for hallux valgus. Pre- and post-operative (6 weeks after surgery) radiological assessments of the IMA and HVA were based on weight-bearing dorso-plantar radiographs. Radiographic measurements were conducted by two foot & ankle fellowship trained consultant surgeons (RR, DG). Paired t-tests were used to determine the statistically significant difference between pre- and post-operative measurements. Results: Between January 2017 and December 2019, 401 MICAs were performed in 274 patients. Pre- and post-operative radiograph measurements were collected for 348 feet in 232 patients (219 female; 13 male). The mean age was 54.4 years (range 16.3-84.9, standard deviation (s.d.) 13.2). Mean pre-operative IMA was 15.3° (range 6.5°-27.0°, s.d. 3.4°) and HVA was 33.8° (range 9.3°-63.9°, s.d. 9.7°). Post-operatively, there was a statistically significant improvement in radiological deformity correction; mean IMA was 5.3° (range -1.2°-16.5°, s.d. 2.7°, p<0.001) and mean HVA was 8.8° (range -5.2°-24.0°, s.d. 4.5°, p<0.001). The mean post-operative reduction in IMA and HVA was 10.0° and 25.0° respectively. Conclusion: This is the largest case series demonstrating radiological outcomes following third generation Minimally Invasive Chevron and Akin Osteotomies (MICA) for hallux valgus to date. These data show that this is an effective approach at correcting both mild and severe hallux valgus deformities. Longer term radiological outcome studies are needed to investigate whether there is any change in radiological outcomes. Correlation with patient reported outcomes is planned.

Background:Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.Methods:Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.Results:Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.Conclusion:Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.Level of Evidence:Level IV, retrospective case series.

Background: The Salto Talaris is a fixed-bearing implant first approved in the US in 2006. While early surgical outcomes have been promising, mid- to long-term survivorship data are limited. The aim of this study was to present the survivorship and causes of failure of the Salto Talaris implant, with functional and radiographic outcomes. Methods: Eighty-seven prospectively followed patients who underwent total ankle arthroplasty with the Salto Talaris between 2007 and 2015 at our institution were retrospectively identified. Of these, 82 patients (85 ankles) had a minimum follow-up of 5 (mean, 7.1; range, 5-12) years. The mean age was 63.5 (range, 42-82) years and the mean body mass index was 28.1 (range, 17.9-41.2) kg/m2. Survivorship was determined by incidence of revision, defined as removal/exchange of a metal component. Preoperative, immediate, and minimum 5-year postoperative AP and lateral weightbearing radiographs were reviewed; tibiotalar alignment (TTA) and the medial distal tibial angle (MDTA) were measured to assess coronal talar and tibial alignment, respectively. The sagittal tibial angle (STA) was measured; the talar inclination angle (TIA) was measured to evaluate for radiographic subsidence of the implant, defined as a change in TIA of 5 degrees or more from the immediately to the latest postoperative lateral radiograph. The locations of periprosthetic cysts were documented. Preoperative and minimum 5-year postoperative Foot and Ankle Outcome Score (FAOS) subscales were compared. Results: Survivorship was 97.6% with 2 revisions. One patient underwent tibial and talar component revision for varus malalignment of the ankle; another underwent talar component revision for aseptic loosening and subsidence. The rate of other reoperations was 21.2% ( n = 18), with the main reoperation being exostectomy with debridement for ankle impingement ( n = 12). At final follow-up, the average TTA improved 4.4 (± 3.8) degrees, the average MDTA improved 3.4 (± 2.6) degrees, and the average STA improved 5.3 (± 4.5) degrees. Periprosthetic cysts were observed in 18 patients, and there was no radiographic subsidence. All FAOS subscales demonstrated significant improvement at final follow-up. Conclusions: We found the Salto Talaris implant to be durable, consistent with previous studies of shorter follow-up lengths. We observed significant improvement in radiographic alignment as well as patient-reported clinical outcomes at a minimum 5-year follow-up. Level of Evidence: Level IV, retrospective case series.

Severe Hallux Valgus

Background: A proximal spherical metatarsal osteotomy was devised to correct not only varus deviation of the first metatarsal, but also dorsiflexion. We expected to increase the medial longitudinal arch by adding plantar flexion at the osteotomy site. To investigate the limitations of this procedure for feet with severe hallux valgus, a followup study was performed on patients with preoperative hallux valgus angles greater than or equal to 40 degrees. Materials and Methods: Forty-eight feet in 37 patients (10 male, 27 female) (60 years; range, 20 to 84 years) were investigated. Mean followup was 4 years and 1 month, ranging from 2 to 8 years. The spherical osteotomy was performed using a curved chisel. A distal soft tissue procedure was done at the same time. Twenty feet received combined operations for their combined deformities. Results: While 81% of patients were satisfied with the results, 50% of those with preoperative hallux valgus angles greater than or equal to 50 degrees had postoperative hallux valgus angle greater than or equal to 20 degrees. In these patients, correction of metatarsus primus varus was good, but correction of valgus deviation of the hallux was fair. Mean correction toward plantar flexion was 1.5 degrees and no increase in arch height was achieved. Conclusion: The proximal spherical osteotomy could consistently achieve satisfactory results for the patients with hallux valgus angles less than 50 degrees. However, the corrections were worse in feet with more severe deformities. Furthermore, plantarflexion at the osteotomy site was offset by displacement at the first tarsometatarsal joint. If plantarflexion is indispensable, arthrodesis of the tarsometatarsal joint is recommended. Level of Evidence: IV, Retrospective Case Series

Background: Arthroscopic debridement has been used in the treatment of early stages of hemophilic ankle arthropathy. The aim of this procedure is to alleviate pain, improve function, and diminish bleeding episodes. Evaluation of patient-reported outcomes of arthroscopic debridement for hemophilic ankle arthropathies was evaluated in this study. Methods: Fifteen patients with hemophilia who had undergone arthroscopic debridement between 2008 and 2017 were included in this study. Preoperative American Orthopaedic Foot & Ankle Society Score (AOFAS) and Foot Function Index (FFI) with its subscales were obtained. Patient-reported outcome was measured using FFI at the latest follow-up. Radiologic severity of hemophilic arthropathy was assessed with the Pettersson score. Preoperative and postoperative intraarticular bleeding frequencies of the hemophilic patients were compared. Results: Patients experienced statistically significant improvements of FFI and its subscales. Median preoperative FFI scores dropped from 42.2% to 22.2% postoperatively. Median value for the Pettersson score was 3. Annual median bleeding frequency of the study group was 18 preoperatively and 1.5 postoperatively ( P = .002). Conclusion: By assessing patient-reported outcomes, pain and functional restrictions associated with hemophilic ankle arthropathy were improved following arthroscopic debridement. By means of subjective measures, this procedure was effective. Level of Evidence: Level IV, retrospective case series.

Abstract Background This study aimed to investigate the efficacy of percutaneous hemiepiphysiodesis for gradual correction of symptomatic juvenile hallux valgus (HV) deformity. Methods Between 2012 to 2014, 24 patients with symptomatic juvenile HV were treated by combined percutaneous medial drilling hemiepiphysiodesis of the first proximal phalanx and lateral transphyseal screw hemiepiphysiodesis of the first metatarsal at our institution. Twenty-one of 24 patients fulfilled inclusion criteria had a complete radiological and clinical follow-up of at least 2 years. Preoperative and postoperative radiographs of the feet were reviewed for measurements of hallux valgus angle (HVA), intermetatarsal angle (IMA), proximal metatarsal articular angle (PMAA), proximal phalangeal articular angle (PPAA), and metatarsal length ratio (MTLR). Clinical outcomes were assessed using the AOFAS hallux metatarsophalangeal-interphalangeal score. Results The study included 21 consecutive patients (37 ft) for analysis. The mean age at surgery was 12.0 years (SD = 1.3) and mean follow-up after surgery was 35.1 months (SD = 6.0). With the data available, the HV deformity improved in terms of the reduction of HVA by a mean of 4.7 degrees (P < .001) and the reduction of IMA by 2.2 degrees (P < .001). The PMAA and PPAA also improved significantly in the anteroposterior plane; however, the PMAA difference was insignificant in lateral plane as expected. The mean difference in the MTLR was 0.00 (P = .216) which was indicative of no length discrepancy between first and second metatarsals. The AOFAS score increased from 68.7 to 85.2 (P < .001). In correlation analysis, time to physeal closure was significantly correlated with the final HVA change (r = −.611, P = .003). Conclusion Although combined hemiepiphysiodesis does not create a large degree of correction as osteotomy, yet it did improve HV deformity with adequate growth remaining in our series. It is a procedure that can be of benefit to patients with symptomatic juvenile HV from this minimal operative approach before skeletal maturity.
