Adult Acquired Flatfoot Deformity

Background: Adult acquired flatfoot deformity (AAFD) and hallux valgus (HV) are common foot and ankle deformities. Few studies have reported the changes in radiographic parameters of HV after reconstructive surgery for AAFD. This study aimed to evaluate the changes in radiographic parameters of HV and analyze the risk factors for increased HV after correction of AAFD. Methods: Adult patients with flexible AAFD who underwent similar bony procedures including medializing calcaneal osteotomy and Cotton osteotomy were included. Radiographic parameters were measured on weightbearing radiographs preoperatively, postoperatively, and at the final follow-up. Patients were divided into hallux valgus angle (HVA) increased and HVA nonincreased groups; logistic regression analysis was performed to identify risk factors affecting increased HV. Results: Forty-six feet of 43 patients were included. After AAFD reconstructive surgery, the tibial sesamoid position improved by 1 grade, but the HVA increased 4 degrees in average. Further, 21 of 46 feet (46%) showed an HVA increase ≥5 degrees immediately after AAFD correction surgery. Preoperative talonavicular coverage angle <21.6 degrees was a risk factor associated with HV increase immediately after the surgery. Conclusion: In this case series, using plain radiographs to measure standard parameters of foot alignment, we found the association between AAFD correction and HV deformity measures somewhat paradoxical. Correction of overpronation of the hindfoot and midfoot appears to improve the first metatarsal rotational deformity but may also increase HVA. A lower preoperative talonavicular coverage angle was associated with an increase of the HVA after surgery. Level of Evidence: Level IV, case series study.

Adult Acquired Flatfoot Deformity

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

Objective: To present initial radiographic results of surgical correction of the hallux valgus angle (HVA) and the intermetatarsal angle (IMA) using the percutaneous Bianchi system (PBS) technique. Methods: Seventeen patients with moderate to severe hallux valgus (HV) were exclusively treated with the PBS technique and assessed radiographically preoperatively and during the postoperative period, from January 2019 to January 2020. The degree of deformity correction was recorded, based on the HVA and the IMA. Stata (v. 14.0) software was used for statistical analyses. Pre-surgical and post-surgical mean HVA and IMA were compared using Student’s t test for paired samples and the McNemar test was used to compare HVA and IMA categories. Statistical significance was set at 5% and 95% confidence intervals were estimated. Results: Both HVA and IMA were reduced significantly during the assessment period. Mean radiographic correction of the HVA was 15.1° and mean radiographic correction of the IMA was 7.3. Conclusions: According to the results presented, use of the PBS technique achieved adequate correction of the radiographic parameters of the patients who underwent the treatment as proposed, although it is necessary to conduct additional studies with longer follow-up to achieve a higher recommendation level.

Adult Acquired Flatfoot Deformity

Category: Bunion; Hindfoot; Midfoot/Forefoot Introduction/Purpose: Arthrodesis of the first tarsometatarsal (TMT-1) joint is a widely accepted procedure for treatment of hallux valgus (HV) with medial column instability secondary to unstable first ray, midfoot arthritis, and severe or recurrent deformities with high intermetatarsal angles (IMA). This study aimed to evaluate clinical and radiographic outcomes in patients with mild-to-severe HV who underwent TMT-1 arthrodesis and proximal hindfoot correction for adult acquired flatfoot deformity (AAFD). Methods: All patients with symptomatic HV and AAFD who failed conservative management underwent TMT-1 fusion and proximal hindfoot correction (medial displacement calcaneal osteotomy, lateral column lengthening, subtalar fusion, or tibiotalocalcaneal fusion) by one of three senior foot and ankle surgeons at a single tertiary center between January 2006 and December 2018 were included in our retrospective case series. Demographics, clinical outcomes, patient comorbidity information, and radiographic outcomes including hallux valgus angle (HVA), IMA 1-2, hallux valgus interphalangeus angle, distal metatarsal articular angle, and sesamoid station were collected. The primary outcome was change in HVA measured as the difference between final postoperative and preoperative weight bearing HVA measurements. Secondary outcomes were reoperation, minor complications (local wound care, use of antibiotics, and skin dehiscence), and change in radiographic measurements. Results: With an average follow up of 26 months, 155 patients (17.4% male, 82.6% female; average age 59.0 years old, range 18 to 84) met inclusion. The average change in HVA was -18.6 degrees (range +15.8 to -81.0). There was a total of 85 reoperations in 35.5% (n=55; 48 hardware removal). Minor complications were present in 18.7% (n=29; 25 local wound care, 23 use of antibiotics, and 10 skin dehiscence). 44.5% (n=69) had no evidence of recurrent HV while mild, moderate, and severe grade bunions were present in 40.0% (n=62), 5.2% (n=8), and 0.6% (n=1). Improvement in overall bunion grade was maintained in 69.7% (n=108) with no change in 19.4% (n=30). Hallux varus was present in 9.7% (n=15; 3 underwent TMT-1 arthrodesis). Conclusion: The present study demonstrates a significant improvement in HVA following TMT-1 arthrodesis and proximal hindfoot correction for AAFD. The majority of patients undergoing TMT-1 arthrodesis and proximal hindfoot correction for AAFD obtain and maintain improvement in the radiographic severity of their bunions. However, patients should be counseled concerning expectations with regards to outcomes associated with complex AAFD reconstructions.

Background: Microfracture is the most common reparative surgery for osteochondral lesions of the talus (OLTs). While shown to be effective in short- to midterm outcomes, the fibrocartilage that microfracture produces is both biomechanically and biologically inferior to that of native hyaline cartilage and is susceptible to possible deterioration over time following repair. With orthobiologics being proposed to augment repair, there exists a clear gap in the study of long-term clinical outcomes of microfracture to determine if this added expense is necessary. Methods: A retrospective review of patients undergoing microfracture of an OLT with a single fellowship-trained orthopedic surgeon from 2007 to 2009 was performed. Patients meeting the inclusion criteria were contacted to complete the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscales and visual analog scale (VAS) for pain, as well as surveyed regarding their satisfaction with the outcome of the procedure and their likelihood to recommend the procedure to a friend with the same problem using 5-point Likert scales. Patient demographics were reviewed and included for statistical analysis. Results: Of 45 respondents, 3 patients required additional surgery on their ankle for the osteochondral defect, yielding a 10-year survival rate of 93.3%. Of surviving cases, 90.4% (38/42) reported being “extremely satisfied” or “satisfied” with the outcome of the procedure. The VAS score at follow-up averaged 14 out of 100 (range, 0-75), while the FAAM-ADL and FAAM-Sports scores averaged 90.29 out of 100 and 82 out of 100, respectively. Thirty-six patients (85.7%) stated that their ankle did not prevent them from participating in the sports of their choice. Conclusion: The current study represents a minimum 10-year follow-up of patients undergoing isolated arthroscopic microfracture for talar osteochondral defects, with a 93.3% survival rate and 85.7% return to sport. While biological adjuvants may play a role in improving the long-term outcomes of microfracture procedures, larger and longer-term follow-up studies are required for procedures using orthobiologics before their cost can be justified for routine use. Level of Evidence: Level IV, retrospective cohort case series study.

Background: Midfoot arthrodesis has long been successfully included in the treatment paradigm for a variety of pathologic foot conditions. A concern with midfoot arthrodesis is the rate of nonunion, which historically has been reported between 5% and 10%. Plantar plating has also been noted to be more biomechanically stable when compared to traditional dorsal plating in previous studies. Practical advantages of plantar plating include less dorsal skin irritation and the ability to correct flatfoot deformity from the same medial incision. The purpose of this study is to report the arthrodesis rate, the success of deformity correction, and the complications associated with plantar-based implant placement for arthrodesis of the medial column. Methods: A retrospective review was undertaken of all consecutive patients between 2012 and 2019 that underwent midfoot arthrodesis with plantar-positioned implants. Radiographic outcomes and complications are reported on 62 patients who underwent midfoot arthrodesis as part of a correction for hallux valgus deformity, flatfoot deformity, degenerative arthritis, Lisfranc injury, or Charcot neuroarthropathy correction. Results: Statistically significant improvement was seen in the lateral talus–first metatarsal angle (Meary angle) and medial arch sag angle for patients treated for flatfoot deformity correction. In patients treated for hallux valgus deformity, there was a reduction in the intermetatarsal angle from 15.4 to 6.8 degrees. The overall nonunion rate was 6.45% in all patients. The rate of nonunion was higher at the NC joint compared to the TMT joint and with compression claw plates. One symptomatic nonunion required revision surgery (1.7%). There were no nonunions when excluding neuroarthropathy patients and smokers. The odds ratio (OR) for nonunion in patients with neuroarthropathy was 6.05 ( P < .05), and in active smokers the OR was 2.33 ( P < .05). Conclusion: Plates placed on the plantar bone surface for midfoot arthrodesis achieved and maintained deformity correction with rare instances of symptomatic hardware for a variety of orthopedic conditions. An overall clinical and radiographic union rate of 94% was achieved. The radiographic union rate improved to 100% when excluding both neuroarthropathy patients and smokers. The incidence of nonunion was higher in smokers, neuroarthropathy patients, naviculocuneiform joint fusions, use of compression claw plates, and when attempting to fuse multiple joints. Incisional healing complications were rarely seen other than in active smokers. Level of Evidence: Level IV, case series.

Background: The incidence rate of venous thrombotic events (VTEs) following foot and ankle surgery is low. Currently, there is no consensus regarding postoperative prophylaxis or evidence to support risk stratification. Methods: A 2-part study assessing the incidence and factors for the development of VTE was conducted: (1) a retrospective observational cohort study of 22 486 adults to calculate the overall incidence following foot and/or ankle surgery from January 2008 to May 2011 and (2) a retrospective matched case-control study to identify risk factors for development of VTE postsurgery. One control per VTE case matched on age and sex was randomly selected from the remaining patients. Results: The overall incidence of VTE was 0.9%. Predictive risk factors in bivariate analyses included obesity, history of VTE, history of trauma, use of hormonal replacement or oral contraception therapy, anatomic location of surgery, procedure duration 60 minutes or more, general anesthesia, postoperative nonweightbearing immobilization greater than 2 weeks, and use of anticoagulation. When significant variables from bivariate analyses were placed into the multivariable regression model, 4 remained statistically significant: adjusted odds ratio (aOR) for obesity, 6.1; history of VTE, 15.7; use of hormone replacement therapy, 8.9; and postoperative nonweightbearing immobilization greater than 2 weeks, 9.0. The risk of VTE increased significantly with 3 or more risk factors ( P = .001). Conclusion: The overall low incidence of VTE following foot and ankle surgery does not support routine prophylaxis for all patients. Among patients with 3 or more risk factors, the use of chemoprophylaxis may be warranted. Level of Evidence: Level III, retrospective case series.

Objective To (1) describe the epidemiology of household rodenticides poisoning in Hong Kong, (2) evaluate the proportion of patients who have develop coagulopathy after rodenticide poisoning, (3) identify the risk factors for developing coagulopathy in rodenticide poisoning. Design Case series study. Setting Sixteen accident and emergency departments in Hong Kong. Patients Patients with household rodenticide ingestion who presented to accident and emergency departments during the period from July 2008 to February 2012. Results 110 patients were reported to have rodenticide exposure during the study period. Eighty-seven patients were included in the final analysis. The mean age was 40.1 and the male-to-female ratio was 1.29:1 (49:38). Most patients (91%) took the rodenticide intentionally. Sixty-nine patients (79%) exposed to anticoagulants type of rodenticide based on history or laboratory findings. The ingredient of the rodenticide ingested in 18 patients (21%) was untraceable. The only clinically significant presentation reported after rodenticide exposure was coagulopathy. Thirty-one patients (36%) developed coagulopathy with an international normalised ratio greater or equal to 1.3. Clinical significant bleeding was only observed in one patient. Presence of coagulopathy in rodenticide poisoning was significantly associated with older patient, intentional ingestion, ingestion of warfarin, ingestion of more than one pack and presence of co-ingestion. Multiple logistic regression analysis showed that only two factors were independent predictor of coagulopathy: Ingestion of warfarin rodenticide (p=0.001, odds ratio [OR] = 18.20, 95% confidence interval [CI]=3.44-96.42), and ingestion of more than one pack of rodenticide (p=0.02, OR=10.01, 95% CI=1.43-69.87). Conclusions Clinically significant household rodenticide poisoning in Hong Kong is solely related to ingestion of anticoagulant type of rodenticide. Patients who have ingested warfarin rodenticide and higher ingestion dose are more likely in developing coagulopathy. (Hong Kong j.emerg.med. 2014;21:339-345)

Background: The forefoot abduction component of the flexible adult-acquired flatfoot can be addressed with lengthening of the anterior process of the calcaneus. We hypothesized that the step-cut lengthening calcaneal osteotomy (SLCO) would decrease the incidence of nonunion, lead to improvement in clinical outcome scores, and have a faster time to healing compared with the traditional Evans osteotomy. Methods: We retrospectively reviewed 111 patients (143 total feet: 65 Evans, 78 SLCO) undergoing stage IIB reconstruction followed clinically for at least 2 years. Preoperative and postoperative radiographs were analyzed for the amount of deformity correction. Computed tomography (CT) was used to analyze osteotomy healing. The Foot and Ankle Outcome Scores (FAOS) and lateral pain surveys were used to assess clinical outcomes. Mann-Whitney U tests were used to assess nonnormally distributed data while χ2 and Fisher exact tests were used to analyze categorical variables (α = 0.05 significant). Results: The Evans group used a larger graft size ( P < .001) and returned more often for hardware removal ( P = .038) than the SLCO group. SLCO union occurred at a mean of 8.77 weeks ( P < .001), which was significantly lower compared with the Evans group ( P = .02). The SLCO group also had fewer nonunions ( P = .016). FAOS scores improved equivalently between the 2 groups. Lateral column pain, ability to exercise, and ambulation distance were similar between groups. Conclusion: Following SLCO, patients had faster healing times and fewer nonunions, similar outcomes scores, and equivalent correction of deformity. SLCO is a viable technique for lateral column lengthening. Level of Evidence: Level III, retrospective cohort study.

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.
