Radiographic Measurements in Patients with Hallux Valgus Before and After Proximal Crescentic Osteotomy

Background: Shortening and dorsiflexion of the first metatarsal are known potential side effects of metatarsal osteotomies for hallux valgus (HV) with the potential to cause transfer metatarsalgia. We compared the effect of the first tarsometatarsal joint arthrodesis (Lapidus procedure), proximal lateral closing wedge osteotomy (PLCWO), and intermetatarsal suture button fixation procedures on the length and dorsiflexion of the first ray. Methods: We retrospectively evaluated 105 feet in 99 patients with 30 weeks of follow-up. The average age was 54 years. Seventy-four feet had a Lapidus procedure, 12 had a PLCWO, and 19 had intermetatarsal suture button fixation. Digital radiographic measurements were made for the pre- and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), absolute and relative shortening of the first ray, and dorsiflexion. Results: Preoperative HVA and IMA did not differ between treatment groups ( P > .05 for each). Similar corrections of HVA (30.5-13.5 degrees) were achieved between all groups ( P > .05). The IMA was improved more in the Lapidus group (14.3-6.5 degrees) compared with the suture button fixation group (14.2-8.1 degrees) ( P = .045). There were significant differences in the change in absolute first cuneiform–metatarsal length (FCML) between the Lapidus (–1.6 mm), PLCWO (–2.3 mm), and intermetatarsal suture button fixation (+1.9 mm) procedure ( P = .004). There were also significant differences in relative first metatarsal shortening between the Lapidus (0.1 mm relative shortening), PLCWO (1.1 mm relative shortening), and intermetatarsal suture button fixation (1.3 mm lengthening) procedure ( P < .001). The average dorsiflexion differed between the Lapidus (1.8 degrees) and suture button fixation (0.4 degrees) groups ( P = .004). Conclusion: Intermetatarsal suture button fixation relatively lengthened the first ray, the Lapidus procedure maintained length, and the PLCWO relatively and absolutely shortened it. Dorsiflexion may be higher with the Lapidus and osteotomy procedures. Level of Evidence: Level III, retrospective comparative series.

Radiographic Alignment

Prospective, concurrent-cohort study. To establish the relationship between radiographic alignment parameters and functional CoE measurements at one week before and at three months after realignment surgery in ADS patients. Adult degenerative scoliosis (ADS) represents a significant healthcare burden with exceedingly high and increasing prevalence, particularly among the elderly. Radiographic alignment measures and patient-reported outcomes currently serve as the standard means to assess spinal alignment, deformity, and stability. Neurological examinations have served as qualitative measures for indicating muscle strength, motor deficits, and gait abnormalities. Three-Dimensional motion analysis is increasingly being used to identify and measure gait and balance instability. Recently, techniques have been established to quantify balance characteristics described by Dubousset as the “cone of economy” (CoE). The relationship between radiographic alignment parameters and CoE balance measures of ADS patients before and after realignment surgery is currently unknown. 29 ADS patients treated with realignment surgery. Patients were evaluated at one week before realignment surgery and at their three-month follow-up examination. During each evaluation, patients completed self-reported outcomes (visual analog scales for pain, Oswestry Disability Index, SRS22r) and a functional balance test. Mean changes in dependent measures from before to after surgery were compared using paired t-tests. Pearson correlations were used to test for significant correlations between changes in radiographic and CoE measures. Significant improvements were found for all patient-reported outcomes, in several radiographic measures, and in CoE measures. Improvements of scoliosis Cobb angle, coronal pelvic tilt, lumbar lordosis, and thoracic kyphosis showed significant correlations with CoE sway and total distance measures at both the center of mass and center of the head. Improved radiographic alignment measures significantly correlated with improved CoE balance measures among ADS patients treated with realignment surgery at their three-month follow-up. These findings indicate that functional balance evaluations when used in conjunction with radiographic measurements, may provide a more robust and improved patient-specific sensitivity for postoperative assessments. CoE balance may represent a new measure of added value for surgical intervention of ADS.

The Mean

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.

Symptom Level

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. Level of Evidence: Level IV, retrospective case series.

Category: Midfoot/Forefoot Introduction/Purpose: This study aimed to investigate the pedobarographic characteristics of tarsometatarsal instability and to identify factors associated with pedobarographic first tarsometatarsal instability in patients with hallux valgus deformity. Methods: Fifty-seven patients (mean age, 59.7 years; standard deviation, 11.4 years; 6 men and 51 women) with a hallux valgus angle (HVA) greater than 15° were included. All patients underwent a pedobarographic examination along with weight-bearing anteroposterior (AP) and lateral foot radiography. Radiographic measurements were compared between the two groups with and without pedobarographic first tarsometatarsal instability. The association between the radiographic and pedobarographic parameters of the first tarsometatarsal instability was analyzed using the chi-square test. Binary logistic regression analysis was performed to identify significant factors affecting pedobarographic first tarsometatarsal instability. Results: HVA (p<0.001), the intermetatarsal angle (p=0.001), and AP talo-first metatarsal angle were significantly different between the pedobarographically stable and unstable tarsometatarsal groups. There was no significant association between radiographic and pedobarographic instabilities of the first tarsometatarsal joint (p=0.924). HVA was found to be the only significant factor affecting pedobarographic tarsometatarsal joint instability (p=0.001). Conclusion: The pedobarographic examination has possible clinical utility in evaluating first tarsometatarsal joint instability in patients with hallux valgus deformity. Patients with greater HVA need to be carefully monitored for the presence of first tarsometatarsal instability, and the necessity of the Lapidus procedure should be considered.

Purpose Foot and ankle deformities are common orthopaedic disorders in children with Down syndrome. However, radiographic measurements of the foot and ankle have not been previously reported. The aim of this study is to describe the foot and ankle deformity in children with Down syndrome. Methods Children who had foot and ankle radiographs in the standing weight-bearing position were selected. Three groups of patients were identified. The relationship of radiographic measurements with age, body mass index and pain is discussed. In all, 41 children (79 feet) had foot radiographs and 60 children (117 ankles) had ankle radiographs, with 15 children overlapping between Groups I and II. Results In Group I, hallux valgus deformity was seen before ten years of age and hallux valgus angle increased afterwards. Metatarsus adductus angle showed a significant increase (p = 0.006) with obesity and was higher in patients who had foot pain (p = 0.05). In Group II, none of the ankle measurements showed a significant difference with age or body mass index percentiles. Tibiotalar angle (TTA) and medial distal tibial angle (MDTA) were higher in patients who had ankle pain. In Group III, correlation analysis was performed between the different measurements with the strongest correlations found between TTA and MDTA. Conclusion In children with Down syndrome, radiographic evaluation of the foot and ankle reveals higher prevalence of deformities than clinical examination. However, foot and ankle radiographs are needed only for symptomatic children with pain and gait changes. Level of Evidence Level IV - Prognostic Study
