Category: Hindfoot Introduction/Purpose: An adult acquired flat foot (AAFD) is a complex 3D deformity. A medializing calcaneal osteotomy (MCO) is a surgical procedure frequently performed to correct the valgus alignment of the hindfoot in a stage II AAFD, when conservative measurements fail. However currently little is known on its accurate influence regarding the hindfoot alignment (HA). The aim is therefore to assess the influence of a MCO on the 3D HA using computer aided software analysis of the images retrieved from a weightbearing cone beam CT (WBCT). Methods: Twelve patients with a mean age of 49,4 years (range 18-67yrs) were prospectively included in a pre-post study design. Indications for surgical correction by a MCO with a solitary translation consisted of an AAFD stage II (N=10) and a posttraumatic valgus deformity (N=2). Fixation of the osteotomy was performed by a step-plate or double screw. WBCT was obtained pre- and post-operative. Images were subsequently segmented to allow a HA calculation in 3D(HA3D) by an angle between the anatomical tibia axis and the axis connecting the computed inferior calcaneuspoint and the centroid of the talus in the coronal plane based on a Cartesian coordinatesystem(Fig 1A, C). The tibia in the HA3D was separately assessed by the anatomical tibia axis (TAx 3D) and the axis to determine the tibial rotation(TR 3D) in the axial plane by connecting the computed most outer point of the anterior and posterior tubercle of the incisura fibularis(Fig 2A, D). Results: The mean medial translation of the calcaneal osteotomy during surgery was 5.72 mm (SD = 3.9). The mean HA3D pre-operatively equaled 18.21 degrees of valgus (SD = 6.6) and post-operatively 9.31 degrees of valgus (SD = 6.18). The Paired Student’s t-test showed a significant correction of 8.89 degrees (95%CI [5.99, 11.80], P<0.001). The mean TAX 3D pre-operatively was 6.80 degrees of valgus (SD = 3.38) and post-operatively 4.11 degrees of valgus (SD = 2.77), with a significant difference of 2.69 degrees (95%CI [1.79, 3.59], P <0.001). The mean TR3D pre-operatively was -27.11 degrees (SD = 4.77) and post-operatively - 28.80 degrees (SD = 5.98) and showed a significant difference of 1.69 degrees (95%CI [0.41, 2.97], P = 0,016). Conclusion: This study shows an effective correction of the valgus hindfoot in an AAFD. It appears that the correction is not only situated in the calcaneus but also to a lesser extent in the tibia and this resulted in 15% of the achieved HA correction. The novelty is the 3D weightbearing assessment of a hindfoot correction and the shown influence on the tibia. This information could be of use to take in to account when performing a pre-operative planning of a hindfoot deformity.

Category: Hindfoot Introduction/Purpose: An adult-acquired flatfoot deformity is a three-dimensional (3D) condition characterized by a loss of the medial longitudinal arch, valgus alignment of the hindfoot, and abduction of the midfoot. When conservative measures are not sufficient, a medializing calcaneal osteotomy (MCO) is frequently performed to correct the deformity, but there is lack of data on the associated three-dimensional variables defining the final correction. A possible reason for this shortcoming could be the current image-based analyses, mainly performed on bi-dimensional radiographs. These are hampered by errors in 3D rotations and superimposition of bony structures. The aim of this study was therefore to assess the correlation between the preoperative hindfoot valgus deformity and calcaneal osteotomy angle and the postoperative calcaneal displacement by use of weightbearing CT (WBCT). Methods: Weight-bearing CT scans obtained pre- and post-operatively were analyzed for sixteen patients with a mean age of 49.4 years (range: 18-66 years). Indication for surgery was adult-acquired flat foot deformity stage II. Based on the WBCT images, pre- and post-operative 3D bone morphological models of the tibia, talus, calcaneus, and the second metatarsal were created, on which anatomical bony landmarks were computationally identified to define a Foot Anatomical reference Frame (FAF). This FAF was used to measure valgus deformity pre- and post-operatively, inclination of the osteotomy plane, and displacement of the calcaneus (Fig. 1). Linear regression was conducted to assess the relationship between these measurements. Results: On average, the hindfoot valgus changed from 13.1° (±4.6) preoperatively to 5.7° (±4.3) postoperatively. A mean inferior displacement of 3.2 mm (±1.3) was observed along the osteotomy with a mean inclination angle of 54.6° (±5.6), 80.5° (±10.7), - 13.7° (±15.7) in the axial, sagittal and coronal planes, respectively. A statistically significant positive relationship (P < .05, R2 = 0.6) was found between the preoperative valgus, the axial osteotomy inclination, and the inferior displacement. Conclusion: This study shows that the degree of preoperative valgus of the hindfoot and the axial osteotomy angle are predictive factors for the amount of postoperative plantar displacement of the calcaneus. These findings contrast the general recommendation of performing a 90° calcaneal osteotomy angle, i.e. perpendicular to the lateral calcaneal wall in every patient. The obtained factors should be taken into account when performing a MCO and could be integrated in a computer-based pre- operative planning.

Abstract Background Evans calcaneal lengthening osteotomy is used to treat symptomatic flexible flatfoot when conservative treatment fails. Grafts such as autologous iliac bone grafts, allografts, and xenografts are implanted at the osteotomy site to lengthen the lateral column of the hindfoot. This study aimed to present the outcomes of an autologous mid-fibula bone graft used for calcaneal lengthening in symptomatic pes valgus in adolescents. Methods We retrospectively examined 23 ft of 13 adolescents who underwent surgery between July 2014 and January 2018. The radiological and clinical outcomes (American Orthopaedic Foot and Ankle Society ankle-hindfoot scale scores) were assessed during a mean follow-up of 49.7 (range, 30.9–73.4) months. The mean distance of the lengthening site was measured to evaluate graft sinking or collapse. The Goldberg scoring system was used to determine the degree of union at the donor and recipient sites. Results The calcaneal pitch and the anteroposterior and lateral talo-first metatarsal (Meary) angles showed significant correction, from 14.4 to 19.6 (p < 0.001), and from 14.5 to 4.6 (p < 0.001) and 13.5 to 8.5 (p < 0.001), respectively. The mean distance of the lengthening site showed no significant change (p = 0.203), suggesting no graft sinking or postoperative collapse. The lateral distal tibial angle showed no significant difference (p = 0.398), suggesting no postoperative ankle valgus changes. Healing of the recipient and donor sites occurred in 23 and 21 ft, respectively. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scores improved significantly, from 68.0 to 98.5 (p < 0.001). Conclusions Evans calcaneal lengthening using an ipsilateral mid-fibula bone autograft resulted in significant improvement in clinical and radiological outcomes without ankle valgus deformity. Hence, it could be a treatment option for lateral column calcaneal lengthening in adolescents.

A Prospective Study

Category: Hindfoot Introduction/Purpose: Based on a prospective study, a new method of photographing and measuring of hindfoot alignment based on X-ray was proposed, and its reliability is verified, as well as its application in flatfeet. Methods: This study included 28 patients (40 feet) with flatfeet and 20 volunteers (40 feet) from January to December in 2018. The shooting frame, designed by our team, has been used to take the hindfoot alignment view at 10°, 15°, 20°, 25°, 30° respectively. Our modified tibio-hindfoot angles (THA) at standard Saltzman position (shooting at 20°) were evaluated, and the consistency were compared with the van Dijk method and the modified van Dijk method, and compared with weight-bearing CT. The visibility of tibiotalar space were evaluated in all shooting angles. The consistency of the modified THA method at different projection angles were evaluated. The angle of hindfoot valgus of flatfoot patients was measured with use of the modified THA method, and compared in different shooting angles. Results: The mean THA in standard Saltzman view in normal people were significantly differences between the three evaluation methods (P < 0.001). The results of modified THA method were significantly larger than those of Van Dijk method (P < 0.001) and modified Van Dijk method (P < 0.001). There was no significant difference between the results of modified THA method and the weight-bearing CT (P=0.605), and the intra- and inter-group consistency was the best in modified THA group. The tibiotalar space in the normal group were visible in all cases at 10°, 15°, 20°; and visible in some cases at 25°; and invisible in all cases at 30°. In the flatfoot group, the tibiotalar space were visible in all cases at 10°; and in some cases at 15° and 20°; and invisible in all cases at 25° and 30°. In the normal group, the modified THA was 4.84±1.81° at 10°, 4.96±1.77° at 15°, 4.94±2.04° at 20°. No significant difference was found between the three groups (P=0.616). In the flat foot group, the modified THA of 18 feet, which was visible at 10°, 15° and 20°, was 13.58±3.57° at 10°, 13.62±3.83° at 15° and 13.38±4.06° at 20°. There was no significant difference between the three groups (P=0.425). Conclusion: The modified THA evaluation method is simple to use and has high intra- and inter-group consistency. It can be used to evaluate hindfoot alignment. For patients with flatfeet, the 10° position view and modified THA measurement can be used to evaluate the hindfoot valgus conditions.

Category: Hindfoot Introduction/Purpose: The primary aim of this study was to calculate the mean values of three most frequently measured parameters for hindfoot alignment determination in asymptomatic subjects - hindfoot alignment angle (HAA), hindfoot alignment ratio (HAR), and hindfoot moment arm (HMA). The secondary aim was to determine the relationship between HAR and HAA or HMA using statistical methods. Methods: From January 2014 to June 2019, a total of 1128 asymptomatic subjects were enrolled in this study. With the hindfoot alignment view by Saltzman and el-Khoury, HAA, HAR, and HMA were measured to evaluate the degree of hindfoot varus or valgus deviation. All subjects were divided into subgroups according to sex and age (<45 years old vs >=45 years old). Simple linear regression was performed to draw out the regression formula between HAR and HAA or HMA. Results: The mean HAA, HAR, and HMA for all subjects were -4.07+-3.48o, 0.21+-0.15, and -6.12+-5.22 mm, respectively. By comparing subgroups, female subjects >=45 years old showed the largest valgus deviation (-7.08+-6.34o, P=0.001). To predict HAR using HAA or HMA, the regression formulas were ‘HAR= 0.366 + 0.039 × HAA’ and ‘HAR= 0.361 + 0.025 × HMA.’ Conclusion: Under HAA, HAR, and HMA evaluation, the hindfoot alignment for asymptomatic subjects was valgus deviation. Furthermore, the degree of valgus deviation was the largest in female subjects aged 45 years or older. This can be explained as the progression of adult type flat foot deformity with aging.

Purpose: To determine the effect of the additional first ray osteotomy on hindfoot alignment for the correction of pes plano-valgus. Methods: Data obtained from 37 consecutive patients recruited from 2006 to 2014 who underwent medial displacement calcaneal osteotomy (MDCO) alone (group H) or MDCO followed by medial cuneiform opening wedge osteotomy (MCOWO) (group HF) with a minimum 1-year follow-up were reviewed retrospectively. The mean follow-up periods were 34 and 32 months. Results: Degree of decrease of Talonavicular coverage angle (TNCA) via surgery or postoperative TNCA on standing foot AP radiographs were not significantly different between group H and HF ( p = 0.287). The calcaneal pitch angle and medial cuneiform height on the standing foot lateral radiographs was significantly increased after operation in group HF ( p = 0.01), there was a significant difference with group H as well ( p = 0.033). In group HF, the Meary’s angle was significantly decreased after operation, a significant difference compared to group H ( p = 0.009). Hindfoot alignment angle on the hindfoot alignment view was decreased after operation in both groups but was not significantly different between both groups ( p = 0.410). Hindfoot alignment ratio was also increased after the operation in both groups, but was not different between two groups ( p = 0.783). Conclusion: The additional first ray osteotomy using MCOWO had no correctional power for hindfoot correction, although it caused improvement in some radiographic parameters.

Object Multiple surgical procedures have been described for the management of isolated nonsyndromic sagittal synostosis. Minimally invasive techniques have been recently emphasized, but these techniques necessitate the use of an endoscope and postoperative helmeting. The authors assert that a safe and effective, more “minimalistic” approach is possible, avoiding the use of endoscopic visualization and routine postoperative application of a cranial orthosis. Methods A single-institution cohort analysis was performed on 18 cases involving infants treated for isolated nonsyndromic sagittal synostosis between 2008 and 2010 using a nonendoscopic, minimally invasive calvarial vault remodeling (CVR) procedure without postoperative helmeting. The surgical technique is described. Variables analyzed were: age at time of surgery, sex, estimated blood loss (EBL), operative time, intraoperative complications, postoperative complications, length of stay, pre- and postoperative cephalic index (CI), clinical impressions, and results of a 5-question nonstandardized questionnaire administered to patient caregivers regarding outcome. Results Eleven male and 7 female infants (mean age 2.3 months) were included in the study. The mean duration of follow-up was 16.4 months (range 6–38 months). The mean procedural time was 111 minutes (range 44–161 minutes). The mean length of stay was 2.3 days (range 2–3 days). The mean EBL in all 18 patients was 101.4 ml (range 30–475 ml). One patient had significant bone bleeding resulting in an EBL of 475 ml. Excluding this patient, the mean EBL was 79.4 ml (range 30–150 ml). There were no deaths or intraoperative complications; one patient had a superficial wound infection. The mean CI was 69 preoperatively versus 79 postoperatively, a statistically significant difference (p < 0.0001). Two patients were offered helmeting for suboptimal surgical outcome; one family declined and the single helmeted patient showed improvement at 2 months. No patient has undergone further surgery for correction of primary deformity, secondary deformities, or bony irregularities. Complete questionnaire data were available for 14 (78%) of the 18 patients; 86% of the respondents were pleased with the cosmetic outcome, 92% were happy to have avoided helmeting, 72% were doubtful that helmeting would have provided more significant correction, and 86% were doubtful that further surgery would be necessary. Small, palpable, aesthetically insignificant skull irregularities were reported by family members in 6 cases (43%). Conclusions The authors present a nonendoscopic, minimally invasive CVR procedure without postoperative helmeting. Their small series demonstrates this to be a safe and efficacious procedure for isolated nonsyndromic sagittal synostosis, with improvements in CI at a mean follow-up of 16.1 months, commensurate with other techniques, and with overall high family satisfaction. Use of a CVR cranial orthosis in a delayed fashion can be effective for the infrequent patient in whom this approach results in suboptimal correction.

Foot Reconstruction

Category: Hindfoot Introduction/Purpose: The use of an arthroereisis implant to augment a stage II, flat-foot reconstruction in adults has been described and may improve postoperative alignment. Yet, painful hardware has been reported. Additionally, there are no reports of mid-term follow up on these implants. The purpose of this study is to describe the mid-term clinical and radiographic outcomes as well as complications with the use of an arthroereisis implant as an adjunct procedure for patients undergoing surgical correction of a flexible acquired, stage II, flat-foot deformity as compared to controls Methods: With IRB approval, all patients undergoing stage II, flat-foot reconstruction by the senior author were identified from 2010-2015. A search was conducted to identify patients within this group undergoing implantation of an adjunctive arthroereisis implant during reconstruction. A 2:1 match using age and gender was performed to identify controls undergoing flexor digitorum longus transfer, medial calcaneal osteotomy, spring ligament repair, and Strayer lengthening during the study period. Demographic information, patient records, operative reports, and follow-up radiographs were reviewed. Preoperative and final follow-up, AP and lateral, weightbearing, radiographs measuring talo-1st metatarsal angle, talo-2nd metatarsal angle, and talo-navicular coverage angle were reviewed and recorded. Clinical follow-up was performed to administer satisfaction SF-36 scoring, and to determine survivorship. Patients undergoing additional corrective procedures at the initial surgery or incomplete records were excluded. Results: 48 patients, age 49.7 (range, 16-68), were included, 16 patients received an arthroereisis implant, 4 were metallic and 12 were bioabsorbable. Follow-up was conducted at 3.54 years (range, 1.4-6 years). Radiographic analysis demonstrated significant improvement in alignment from preoperative to mid-term follow-up in both groups. In addition, arthroereisis patients had a statistically significant improvement in correction of talo-navicular coverage angle at final follow-up, 5 degrees ± 3.9, compared to controls, 10.6 degrees ± 6.8. Average SF-36 scores at mid-term follow-up were comparable with no significant difference between cases, 74.6 ± 21.8, and controls, 76.1 ± 15.3 p=0.89. Overall, 84% of patients noted good or excellent satisfaction. Complications included one arthroereisis failure from painful hardware (1/16), one infection in the controls (1/32), and an unrelated mortality. Conclusion: Arthroereisis implants as an adjunct to stage II, flat-foot correction result in improved and maintained radiographic alignment with comparable clinical results to controls at mid-term follow-up. Additionally, the use of the implant demonstrates improved talo-navicular coverage on mid-term radiographs. While painful hardware was noted in a metallic implant, bioabsorbable implants have demonstrated few complications and may be a safe adjunct to stage II, flat-foot correction in adults.

Category: Hindfoot Introduction/Purpose: Previous work has demonstrated that the amount of radiographic hindfoot correction required at the time of adult acquired flatfoot deformity (AAFD) surgical treatment can be predicted by the amount of radiographic deformity present before surgery. Successful outcomes after reconstruction are closely correlated with hindfoot valgus correction. However, it is not clear if differences exist between clinical and radiographic assessment of hindfoot valgus. The purpose of this study was to evaluate the correlation between radiographic and clinical evaluation of hindfoot alignment in patients with stage II AAFD. Methods: Twenty-nine patients (30 feet) with stage II AAFD, 17 men and 12 women, mean age of 51 (range, 20 to 71) years, were prospectively recruited. In a controlled and standardized fashion, bilateral weightbearing radiographic hindfoot alignment views were taken. Radiographic parameters were measured by two blinded and independent readers: hindfoot alignment angle (HAA) and hindfoot moment arm (HMA). Clinical photographs of hindfoot alignment were taken, in three different vertical camera angulations (0, 20 and 40 degrees). Pictures were assessed by the same readers for standing tibiocalcaneal angle (STCA) and resting calcaneal stance position (RCSP). Intra- and interobserver reliability were assessed by Pearson/Spearman’s and intraclass correlation coefficient (ICC), respectively. Relationship between clinical and radiographic hindfoot alignment was evaluated by a linear regression model. Comparison between the different angles (RCSP, STCA and HAA) was performed using Wilcoxon rank sum test. P-values of less than 0.05 were considered significant. Results: We found overall almost perfect intra- (range, 0.91-0.99) and interobserver reliability (range, 0.74-0.98) for all measures. Mean value and confidence interval (CI) for RCSP and STCA were 10.78 degrees (CI: 10.09-11.47) and 12.55 degrees (CI: 11.71- 13.40), respectively. The position of the camera did not influence readings of clinical alignment (p>.05). The mean HMA was 18.74 mm (CI: 16.34-21.14 mm) and the mean HAA was 23.54 degrees (CI: 21.08-25.99). Clinical and radiographic hindfoot alignment were found to significantly correlate (p<.05). However, the radiographic hindfoot alignment (HAA) demonstrated increased valgus when compared to both clinical alignment measurements, with a mean difference of 12.76 degrees from the RCSP (CI: 10.99-14.53, p<.0001) and 10.98 degrees from the STCA (CI: 9.22-12.76, p<.0001). Conclusion: We found significant correlation between radiographic and clinical hindfoot alignment in patients with stage II AAFD. However, radiographic measurements of hindfoot alignment angle demonstrated significantly more pronounced valgus alignment than the clinical evaluation. The results of our study suggest that clinical evaluation of hindfoot alignment in patients with AAFD potentially underestimates the bony valgus deformity. One should consider these findings when using clinical evaluation in the treatment algorithm of flatfoot patients.

Adult Acquired Flatfoot Deformity

Category: Hindfoot; Midfoot/Forefoot Introduction/Purpose: Adult acquired flatfoot deformity is a complex deformity associated with the collapse of the medial longitudinal arch. Several factors have been proposed in the etiology of adult acquired flatfoot deformity including arthritic, neuromuscular, and traumatic conditions; however, posterior tibial tendon dysfunction remains the most common etiology. A spectrum of conditions affecting the posterior tibial tendon has been identified, with tendinitis occurring early in the disease process and tendon rupture occurring at the more advanced stages. Adult-acquired flatfoot deformity requires a complex operative plan that often utilizes several procedures to correct deformity, at both the hindfoot and midfoot. The objective of this study was to compare the efficacy of two different osteotomies commonly used to correct flexible flat feet. Methods: 42 Patients (21 males and 21 females) with stage II PTTD acquired flexible flatfeet were included with a mean age of 49.62 +- 6.2. Twinty-two patients had medial displacement calcaneal osteotomy (MDCO) while 20 cases had latercal column lenghtening (LCL). Strayer procedure, spring ligament plication and FDL transfer were done in all patients. Pre- and Post-operative clinical assessment was done using AOFAS and FFI questionaire. Six radiographic parameters were analyzed, two in the anteroposterior view ( talo-navicular coverage and talo-calcaneal angle), three in lateral view ( talo- first metatarsus angle, talo- calcaneal angle and calcaneal inclination angle) and tibio-calcanal angle in axial view. Results: At a mean follow up of 12 months, significant improvement in AOFAS and FFI scores in MDCO and LCL groups with no significant difference between both groups. Postoperative significant improvements in all radiographic measurements in both groups. LCL group showed significant better correction in TNC and calcaneal inclination angles when compared to MDCO group. However, MDCO procedure showed significantly better correction in axial tibial calcaneal angle. Both techniques correct the deformity, however cases received LCL has better correction than MDCO cases and less reoperation rate. Conclusion: Reconstructions performed with LCL produced a greater change in the realignment of adult acquired flatfoot, maintained more of their initial correction over time, and were associated with a lower incidence of additional surgery than reconstructions with a MDCO of the calcaneus. However, a higher incidence of degenerative change in the hindfoot was observed in the LCL group. The ability of LCL to correct the deformity in anteroposterior and lateral plan and MDCO in lateral and axial plan suggests that proper osteotomy should be planned according to the existing deformity. Combination of both techniques may be required in certain cases.

Adult Acquired Flatfoot Deformity

Purpose. To investigate the effect of cuboid osteotomy lateral column lengthening (LCL) for the correction of stage II B adult-acquired flatfoot deformity in cadaver. Methods. Six cadaver specimens were loaded to 350 N. Flatfoot models were established and each was evaluated radiographically and pedobarographically in the following conditions: (1) intact foot, (2) flatfoot, and (3) cuboid osteotomy LCL (2, 3, 4, and 5 mm). Results. Compared with the flatfoot model, the LCLs showed significant correction of talonavicular coverage on anteroposterior radiographs and talus-first metatarsal angle on both anteroposterior and lateral radiographs (p<.05). Compared with the intact foot, the above angles of the LCLs showed no significant difference except the 2 mm LCL. In terms of forefoot pressure, medial pressure of the 2 mm LCL (p=.044) and lateral pressure of the 3, 4, and 5 mm LCLs showed statistical differences (p<.05), but lateral pressure of the 3 mm LCL was not more than the intact foot as compared to the 4 and 5 mm LCLs, which was less than medial pressure. Conclusion. Cuboid osteotomy LCL procedure avoids damage to subtalar joint and has a good effect on correction of stage II B adult-acquired flatfoot deformity with a 3 mm lengthening in cadavers.
