Impact of Subtalar Distraction Arthrodesis on Ankle Joint: Radiological Insights from Modified Grice-Green Procedure. Life (Basel) 2024; 14:692. [PMID: 38929675 PMCID: PMC11204614 DOI: 10.3390/life14060692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 05/23/2024] [Accepted: 05/27/2024] [Indexed: 06/28/2024] Open
Abstract
Subtalar distraction arthrodesis (SDA) is a surgical procedure designed to treat hindfoot deformities associated with isolated subtalar joint arthritis. In 1996, Fitzgibbons was the first to observe that, in some cases, hindfoot fusion appeared to be associated with the development of tibiotalar valgus tilt. Since then, few studies have addressed this issue. Given that hindfoot fusion can be performed using various techniques, this study investigated the potential tibiotalar joint frontal or sagittal modifications resulting from the modified Grice-Green technique. All the consecutive patients who underwent the modified Grice-Green procedure were included. The patient records were reviewed to extract demographic data. Weight-bearing foot and ankle radiographs were assessed to measure the talar tilt angle and the tibiotalar ratio on the same picture archiving and communication system by three independent observers. A total of 69 patients met the criteria for inclusion. The mean talar tilt showed no substantial changes, since the increase from 1.46 ± 1.62 preoperatively to 1.93 ± 2.19 at a minimum of 8 months postoperatively was not statistically significant (p = 0.47). The average preoperative tibiotalar ratio significantly increased from 33.4 ± 4.4% to 35 ± 4% postoperatively (p = 0.007), although remaining within the normal range, indicating a possible realignment of the posterior facet of the subtalar joint. In conclusion, this study highlights the effectiveness of the modified Grice-Green procedure in achieving a favorable realignment without impacting the ankle joint, particularly regarding tibiotalar valgus tilt.

[PMID: 38523011 DOI: 10.1016/j.fas.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 03/15/2024] [Accepted: 03/16/2024] [Indexed: 03/26/2024]
Abstract
BACKGROUND Finite element (FE) analysis and clinical follow-up were used to evaluate the efficacy of a modified lateral column lengthening (H-LCL) for treating flexible flatfoot. METHODS By applying inclusion and exclusion criteria, we selected patients who underwent H-LCL surgery at our institution from January 2019 to January 2023. We compared the Visual Analog Scale (VAS) scores, American Orthopaedic Foot and Ankle Society (AOFAS) scores, Pain Interference (PI), and Physical Function (PF) scores in Patient-Reported Outcomes Measurement Information System (PROMIS) between preoperative and final follow-up assessments of patients, as well as FE submodels. Furthermore, evaluate the H-LCL's biomechanical characteristics and clinical outcome before and after surgery. RESULTS A total of 66 patients met the criteria. The average surgery time was 69.47 ± 13.22 min, and the follow-up duration was 15.18 ± 6.40 months. In the last follow-up, VAS and PI decreased compared to before surgery, while AOFAS and PF increased compared to before surgery. Meary's angle (dorsoplantar image and lateral image), calcaneal valgus angle, and talonavicular coverage angle decreased compared to before surgery, while the pitch angle increased compared to before surgery. In FE analysis, postoperative tension on the plantar fascia (PF), spring ligament (SL), and posterior tibial tendon (PTT) decreased compared to before surgery, pressure on the talonavicular joint and subtalar joints also decreased compared to before surgery, and there was no significant change in pressure on the calcaneocuboid joint. CONCLUSION H-LCL in correcting flexible flatfoot resulted in a significant improvement of clinical outcome scores and led to good radiological correction of flatfoot deformities. It can reduce the soft tissue and interosseous pressure in maintaining the foot arch.

Correlation of patient reported outcomes with radiographic assessment in progressive collapsing foot deformity reconstruction: A systematic review. Foot Ankle Surg 2024:S1268-7731(24)00065-1.

Abstract
BACKGROUND In progressive collapsing foot deformity (PCFD), the goal of surgery is to obtain a well-balanced plantigrade foot. It remains unclear if restoration of the alignment and subsequent improvement in radiological parameters is associated with improved patient-reported outcome measures (PROMs). The aim of the current systematic review was to investigate whether there is a correlation between radiographic assessment and PROMs in patients treated surgically for flexible PCFD. MATERIALS AND METHODS The study was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A comprehensive literature search was performed in Pubmed, EMBASE, Cochrane Central Register of Controlled Trails (CENTRAL), and KINAHL. We included all the studies reporting both PROMs and radiological outcomes in patients treated surgically for PCFD. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal tool. RESULTS Six retrospective studies were included. Radiological parameters related to forefoot plantarflexion were associated with statistically significant differences in postoperative PROMs. A neutral hindfoot and midfoot position was positively correlated with postoperative PROMs but a statistically significant difference could not be established in all studies. The medial arch height was positively correlated with PROMs, but in one study this was the case only in revision surgeries. CONCLUSION The literature so far suggests restoration of the alignment may be associated with improved PROMs. Future prospective studies that investigate possible radiological and clinical correlations in PCFD surgery are needed.

Abstract
Numerous surgical procedures for the treatment of posterior tibialis tendon (PTT) dysfunction have been developed, including tendon transfers, osteotomies, and arthrodesis. Among these methods, foot and ankle surgeons most frequently use flexor digitorum longus (FDL) tendon transfer in conjunction with medial translational osteotomy of the calcaneus. Formerly, some less invasive techniques have been described to reduce surgical-related complications after FDL tendon transfer. Herein, we introduced a new modification of short-stump FDL tendon fixation to the navicular bone and reported the functional outcomes of the current technique in a patient with PTT dysfunction. In the current technique, the FDL tendon was fixed to the navicular bone via a trans-osseous tunnel using a split PTT stump. This method does not require any kind of fixation devices, such as an interference screw or anchor suture.Level of Evidence: V.

Abstract
BACKGROUND Evans and Hintermann lateral column lengthening (LCL) procedures are both widely used to correct adult acquired flatfoot deformity (AAFD), and have both shown good clinical results. The aim of this study was to compare these two procedures in terms of corrective ability and biomechanics influence on the Chopart and subtalar joints through finite element (FE) analysis. METHODS Twelve patient-specific FE models were established and validated. The Hintermann osteotomy was performed between the medial and posterior facets of the subtalar joint; while, the Evans osteotomy was performed on the anterior neck of the calcaneus around 10 mm from the calcaneocuboid joint surface. In each procedure, a triangular wedge of varying size was inserted at the lateral edge. The two procedures were then compared based on the measured strains of superomedial calcaneonavicular ligaments and planter facia, the talus-first metatarsal angle, and the contact characteristics of talonavicular, calcaneocuboid and subtalar joints. RESULTS The Hintermann procedure achieved a greater correction of the talus-first metatarsal angle than Evans when using grafts of the same size, indicating that Hintermann had stronger corrective ability. However, its distributions of von-Mises stress in the subtalar, talonavicular and calcaneocuboid joints were less homogeneous than those of Evans. In addition, the strains of superomedial calcaneonavicular ligaments and planter facia of Hintermann were also greater than those of Evans, but both generally within the safe range (less than 6%). CONCLUSION This FE analysis study indicates that both Evans and Hintermann procedures have good corrective ability for AAFD. Compared to Evans, Hintermann procedure can provide a stronger corrective effect while causing greater disturbance to the biomechanics of Chopart joints, which may be an important mechanism of arthritis. Nevertheless, it yields a better protection to the subtalar joint than Evans osteotomy. CLINICAL RELEVANCE Both Evans and Hintermann LCL surgeries have a considerable impact on adjacent joints and ligament tissues. Such effects alongside the overcorrection problem should be cautiously considered when choosing the specific surgical method. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
In patients requiring surgical correction of ipsilateral valgus knee and rigid pes planovalgus deformities, the optimal operative sequence is controversial. Growing evidence suggests these 2 deformities are related in etiology and interrelated in disease course. We present the case of a 72-year-old female with concomitant valgus knee and rigid pes planovalgus deformities successfully treated with total knee arthroplasty followed by triple arthrodesis and Achilles lengthening. Surgical correction of these deformities must be carefully planned between the operating surgeons to avoid over- or under-correction of alignment that could further impact gait. In contrast with the limited available literature, the authors recommend correction at the knee first and the foot and ankle second. Further prospective studies are needed to elucidate the best operative sequence in these patients.

Abstract
BACKGROUND This study analyzed the advantages and disadvantages of different procedures for stage IIA progressive collapsing foot deformity (PCFD) through three-dimensional finite element models. METHODS A previous validated stage IIA PCFD FEA model was established consisting of 16 bones, 56 ligaments, 5 muscles and soft tissues. The ligament properties of the spring, deltoid, short plantar and long plantar ligaments, and plantar fascia were attenuated according to a previous publication. Medial column fusion (MCF), medializing calcaneal osteotomy (MCO), lateral column lengthening (LCL), and subtalar joint arthroereisis (SJA) operations were simulated in this model. The indexes of plantar stress distribution, maximum von Mises of the medial and lateral columns, strain of the medial ligaments and plantar fascia that supported the medial longitudinal arch, arch height, talo-first metatarsal angle, calcaneus pitch angle, and talonavicular coverage angle were all compared before and after simulated single-foot weight loading. RESULTS The maximum plantar stress of PCFD decreased with MCO and SJA but increased with MCF and LCL. MCF and LCL failed to significantly reduce the stress on the medial column fragments, thereby increasing their stress. Both MCO and SJA relieved medial plantar stress. MCF had no significant effect on stress relief of the medial ligament. MCO, LCL, and SJA were all shown to reduce the pressure on the medial plantar ligament, with LCL having the most obvious effect. All four procedures corrected the arch deformity; however, MCF was not as effective as the other methods. SJA is the best method for restoring arch height and correcting arch deformities. For stage IIA PCFD, isolated MCF failed to reduce pressure on the medial column; however, isolated MCO significantly reduced the pressure on the medial plantar and ligamentous soft tissues while restoring the foot's arch and correcting the hindfoot valgus. CONCLUSION SJA with type II sinus tarsi implant effectively transferred pressure from the medial plantar tract to the lateral side and restored the arch. Isolated LCL was not found suitable for stage IIA PCFD.

Abstract
BACKGROUND Equinus generally is linked to many foot and ankle pathologies. A reasonably convincing relationship was found between isolated gastrocnemius or Achilles contracture and the flatfoot deformity. Achilles' tightness in flatfoot children can lead to future pain and disability, which makes it more important than other types of flatfeet. Findings in the literature suggest stretching and orthotic management as a conservative treatment for this compound disorder. OBJECTIVE This review aimed to examine the impact of orthotic managements on gastroc-soleus complex tightness in pediatric with flexible flatfoot. STUDY DESIGN Systematic review. METHODS A systematic search of electronic databases (PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science) was performed to find relevant articles. The level of evidence and quality was identified using Downs and Black (1998). This review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS Three hundred fifty-seven studies were found by searching electronic databases. After removing duplicate documents, 190 documents remained. Three other articles were identified from the screened of related references. During title/abstract screening, 193 studies were excluded and no study was selected for full consideration for the present review. CONCLUSIONS In conclusion, no study assessed the impact of orthotic management on gastroc-soleus complex tightness in children with flexible flatfoot. These devices have been proposed in spastic and nonspastic patients. Hence, researches that show whether these devices can be effective on gastrocnemius or Achilles tendon tightness in flatfoot children or not will be worthwhile.

Abstract
Introduction Different methods are used to fix a sliding calcaneal osteotomy for hindfoot varus and valgus deformity. However, information about the effectiveness and limitations of each method is limited. In this meta-analysis, we compare the hardware removal rate, union rate, and complications of three different methods of fixation: plate, headed screw, and headless screw. Methods A systematic review and meta-analysis of published articles were carried out, following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We investigated diverse databases, Web of Science, PubMed, the Cochrane Library, Excerpta Medica database (EMBASE), and Cumulative Index of Nursing and Allied Health Literature (CINAHL), to search articles reporting the use of different calcaneal osteotomy fixations from database inception to October 2021. The primary outcome was the hardware removal rate, and the secondary outcomes of interest were the union rate and complications. Results Of 1,903 articles identified, eight met the inclusion criteria. The highest risk ratio (RR) of the hardware removal rate was detected in the headed screw method (RR: 0.39, 95% confidence interval (CI): 0.26-0.58). However, the highest RR of nonunion was detected in the plate method (RR: 0.02, 95%CI: 0.01-0.07). Regarding complications (infections), the headed screw method presented the highest RR of infection (RR: 0.24, 95%CI: 0.06-0.97). Conclusion This comprehensive review and meta-analysis revealed that the headless screw method may be the most effective fixation option for calcaneal osteotomy with the lowest risk of hardware removal rate, nonunion rate, and complications. Obviously, further studies are needed on a larger number of patients to confirm this finding.

BMC Musculoskelet Disord 2022; 23:751.

Abstract
Background Lateral column lengthening calcaneal osteotomy is a powerful procedure for correcting forefoot abduction in flatfoot deformity. However, it involves the risk of damaging articular facets of the subtalar joint. The optimal method to avoid violating the subtalar joint during lateral column lengthening remained controversial in published reports, implying that the subtalar joint might present anatomical variations among different nationalities. Therefore, the objective of this study was to perform an anatomical study by targeting the healthy Chinese population for the purpose of identifying the optimal procedure for lateral column lengthening calcaneal osteotomy according to anatomical patterns of the subtalar joint. Methods A total of 72 ft from 70 fresh frozen cadavers were obtained from the Department of Anatomy of Central South University. For each foot, soft tissues were surgically removed from the bones, and the calcaneus was completely separated from other bones to recognize the anatomical features of the calcaneus. The distance between the calcaneocuboid joint and the articular facet of the subtalar joint was measured by digital calipers for further analysis. Results Out of the 72 ft, 36.1% had separated anterior and middle facets in the calcaneus, and 63.8% had partly or completely fused anterior and middle facets. In the calcanei with discrete facets, the mean distance from the calcaneocuboid joint to the proximal margin of the anterior facet was 12.75 ± 2.10 mm, and the mean width of the separation between the anterior and middle facets was 2.43 ± 1.41 mm. In the calcanei with partly or completely fused anterior and middle facets, the mean width of the narrowest part of the tarsal sinus was 5.81 ± 0.62 mm and 6.25 ± 0.35 mm, respectively. Conclusions The anatomy of the subtalar joint presents significant individual variations in the Chinese population. Calcanei with partly or completely fused anterior and middle facets were observed in nearly two thirds of individuals. Since the modified Evans procedure might potentially incur damage to the subtalar joint facets, the Hintermann procedure or other modified extra-articular lateral column lengthening procedures may be more applicable to the Chinese population.

Abstract
The correction of the flexible pes planovalgus foot and ankle is a complicated and somewhat controversial topic. After conservative methods fail, there is a wide range of possible soft tissue and bony procedures. The appropriate work up and understanding of the pathomechanics are vital to the correct choice of procedures to correct these deformities. Once the work up and procedure selection are done, the operation must also be technically performed well and with efficiency, as most often the condition is corrected with a variety of procedures. This article discusses some of the most common procedures necessary to fully correct the pes planovalgus foot and discusses the authors' technique and pearls.

J Orthop Sci 2022; 27:429-434. [PMID: 33509698 DOI: 10.1016/j.jos.2020.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 11/27/2020] [Accepted: 12/11/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND This study aimed to assess how the postoperative medial arch height influenced postoperative patient-reported clinical outcomes after surgery for stage Ⅱ acquired adult flatfoot deformity. METHODS A total of 30 feet of 30 patients (7 males, 23 females) who underwent surgery for stage Ⅱ acquired adult flatfoot deformity and could be followed up for at least 2 years were included. The average age at surgery was 60.0 (standard deviation, 13.0) years, and the average follow-up period was 40 (standard deviation, 15.4) months. Among them, 16 patients underwent lateral column lengthening and 14 patients did not. Patient-reported clinical outcomes were evaluated using the Self-Administered Foot Evaluation Questionnaire. Radiographic alignment was evaluated by the talonavicular coverage angle, lateral talo-1st metatarsal angle, medial cuneiform height, medial cuneiform to 5th metatarsal height, and calcaneal pitch. The correlation between postoperative Self-Administered Foot Evaluation Questionnaire and radiographic alignment was assessed with Pearson's correlation analysis. RESULTS Self-Administered Foot Evaluation Questionnaire and radiographic alignment significantly improved postoperatively in all patients (P < 0.0001). In patients with severe deformity who needed lateral column lengthening, lateral talo-1st metatarsal angle was negatively and medial cuneiform to 5th metatarsal height was positively correlated with physical functioning Self-Administered Foot Evaluation Questionnaire subscales (r = -0.56 and 0.55), and medial cuneiform height was positively correlated with physical functioning, social functioning and general health Self-Administered Foot Evaluation Questionnaire subscales (r = 0.70, 0.55 and 0.73, respectively). CONCLUSION Postoperative medial arch height could influence physical functioning, social functioning, and general health in patients with severe stage II adult-acquired flatfoot deformity.

Abstract
BACKGROUND A common challenge in flatfoot reconstruction arises when there are multiple locations of collapse within the medial column. An extension of arthrodesis may lead to complications such as stiffness or adjacent joint arthritis. The purpose of this study was to report outcomes of flatfoot reconstruction using the dynamic medial column stabilization (DMCS) technique, which transfers the flexor hallucis longus (FHL) tendon to the first metatarsal base to support the entire medial column. METHODS We retrospectively reviewed 14 consecutive patients (14 feet) who underwent DMCS as an adjunct to flatfoot reconstruction. In all cases, a medial displacement calcaneal osteotomy and gastrocnemius recession were performed to address hindfoot valgus deformity and heel cord tightness, respectively. Deformity correction was assessed using preoperative and postoperative weightbearing radiographs. The newly defined metatarsal-cuneiform articular angle (MCAA) and naviculo-cuneiform articular angle (NCAA) were measured to assess correction at each medial column joints. Clinical outcomes included the FFI and VAS scores. Any complications related to the surgery were investigated. RESULTS All radiographic parameters significantly improved postoperatively. The sagittal plane correction occurred at all three joints within the medial column. Clinically, both FFI and VAS improved significantly at the final follow-up. One patient developed plantar pain under the first metatarsal head that may have been associated with the overtightening of the transferred tendon. CONCLUSION DMCS using FHL tendon transfer to the first metatarsal base was a useful technique for restoring the medial arch and correcting three planar deformities in the setting of flatfoot deformity.

Abstract
Lateral column lengthening has long been used in conjunction with other soft tissue and bony procedures to correct the midforefoot abduction seen in class B progressive collapsing foot deformity. The effectiveness of this osteotomy to restore the physiologic shape of the foot has been used by foot and ankle surgeons around the world to provide functional improvement for patients suffering from this disease. The overall low complication rates, low nonunion rates, and improved radiographic and functional outcomes provided by lateral column lengthening make this a valuable option for the treatment of class B progressive collapsing foot deformity.

Abstract
The progressive collapsing foot deformity is a complex three-dimensional deformity, including valgus malalignment of the heel. The medial displacement calcaneal osteotomy is an established surgical procedure reliably resulting in an efficient correction of the inframalleolar alignment. However, complications are common, including undercorrection of underlying deformity, progression of hindfoot osteoarthritis and/or deformity, and/or symptomatic hardware.

Abstract
Undiagnosed medial ankle instability can be a prerequisite for pathogenic progression in the foot, particularly for adult acquired flatfoot deformity. With the complex anatomy in this region, and the limitations of each individual investigational method, accurately identifying peritalar instability remains a serious challenge to clinicians. Performing a thorough clinical examination aided by evaluation with advanced imaging can improve the threshold of detection for this condition and allow early proper treatment to prevent further manifestations of the instability.

Abstract
RECOMMENDATION In the treatment of progressive collapsing foot deformity (PCFD), the combination of bone shape, soft tissue failure, and host factors create a complex algorithm that may confound choices for operative treatment. Realignment and balancing are primary goals. There was consensus that preservation of joint motion is preferred when possible. This choice needs to be balanced with the need for performing joint-sacrificing procedures such as fusions to obtain and maintain correction. In addition, a patient's age and health status such as body mass index is important to consider. Although preservation of motion is important, it is secondary to a stable and properly aligned foot.

Abstract
RECOMMENDATION Progressive collapsing foot deformity (PCFD) is a complex 3D deformity with varying degrees of hindfoot valgus, forefoot abduction, and midfoot supination. Although a medial displacement calcaneal osteotomy can correct heel valgus, it has far less ability to correct forefoot abduction. More severe forefoot abduction, most frequently measured preoperatively by assessing talonavicular coverage on an anteroposterior (AP) weightbearing conventional radiographic view of the foot, can be more effectively corrected with a lateral column lengthening procedure than by other osteotomies in the foot. Care must be taken intraoperatively to not overcorrect the deformity by restricting passive eversion of the subtalar joint or causing adduction at the talonavicular joint on simulated AP weightbearing fluoroscopic imaging. Overcorrection can lead to lateral column overload with persistent lateral midfoot pain. The typical amount of lengthening of the lateral column is between 5 and 10 mm. LEVEL OF EVIDENCE Level V, consensus, expert opinion. CONSENSUS STATEMENT ONE Lateral column lengthening (LCL) procedure is recommended when the amount of talonavicular joint uncoverage is above 40%. The amount of lengthening needed in the lateral column should be judged intraoperatively by the amount of correction of the uncoverage and by adequate residual passive eversion range of motion of the subtalar joint.Delegate vote: agree, 78% (7/9); disagree, 11% (1/9); abstain, 11% (1/9).(Strong consensus). CONSENSUS STATEMENT TWO When titrating the amount of correction of abduction deformity intraoperatively, the presence of adduction at the talonavicular joint on simulated weightbearing fluoroscopic imaging is an important sign of hypercorrection and higher risk for lateral column overload.Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%.(Unanimous, strongest consensus). CONSENSUS STATEMENT THREE The typical range for performing a lateral column lengthening is between 5 and 10 mm to achieve an adequate amount of talonavicular coverage.Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%.(Unanimous, strongest consensus).

Abstract
RECOMMENDATION There is evidence that the medial displacement calcaneal osteotomy (MDCO) can be effective in treating the progressive collapsing foot deformity (PCFD). This juxta-articular osteotomy of the tuberosity shifts the mechanical axis of the calcaneus from a more lateral position to a more medial position, which provides mechanical advantage in the reconstruction for this condition. This also shifts the action of the Achilles tendon medially, which minimizes the everting deforming effect and improves the inversion forces. When isolated hindfoot valgus exists with adequate talonavicular joint coverage (less than 35%-40% uncoverage) and a lack of significant forefoot supination, varus, or abduction, we recommend performing this osteotomy as an isolated bony procedure, with or without additional soft tissue procedures. The clinical goal of the hindfoot valgus correction is to achieve a clinically neutral heel, as defined by a vertical axis from the heel up the longitudinal axis of the Achilles tendon and distal aspect of the leg. The typical range when performing a MDCO, while considering the location and rotation of the osteotomy, is 7 to 15 mm of correction. LEVEL OF EVIDENCE Level V, consensus, expert opinion.

Abstract
Background: Operative correction of flatfoot deformity has been well studied in the older population. There is a subset of younger patients without congenital foot deformity that also develop a collapsing flatfoot. However, assessment of outcomes across age groups is limited, especially in the young demographic. The purpose of our study was to compare operative outcomes of flatfoot reconstruction between these 2 age groups. Methods: Seventy-six feet (41 left, 35 right) in 71 patients who underwent flexible flatfoot reconstruction were divided into 2 groups based on age: ≤30 years (n = 22) and >30 years (n = 54). Exclusion criteria included congenital causes of flatfoot (tarsal coalition, vertical talus, overcorrected clubfoot). Average age was 20.8 years (range, 14-30) and 55.4 years (range, 35-74) in the younger and older cohorts, respectively. Preoperative and minimum 2-year postoperative Patient-Reported Outcomes Measurement Information Systems (PROMIS) scores were compared. Five radiographic parameters were assessed pre- and postoperatively: talonavicular coverage angle, lateral talo–first metatarsal angle, lateral talocalcaneal angle, calcaneal pitch, and hindfoot moment arm. Procedures performed and incidence of minor (removal of symptomatic hardware) and major (revision) reoperations were compared. Results: Younger patients were less likely to undergo flexor digitorum longus transfer, first tarsometatarsal fusion, spring ligament repair, and posterior tibial tendon repair (all P < .05). Both younger and older cohorts demonstrated significant improvement in multiple PROMIS domains at an average follow-up of 30.6 (range, 24-44) and 26.8 (range, 24-45) months, respectively ( P = .07). Younger patients demonstrated significantly higher pre- and postoperative Physical Function (mean difference postoperatively, 4.6; 95% confidence interval, 1.5-7.8; P = .03). There were no differences in radiographic parameters postoperatively. There were 8 (36.4%) reoperations (all minor) in the younger group, and 21 (38.9%) reoperations (6 major, 15 minor) in the older group ( P = .84). Conclusion: Our data suggest that age may play a role in clinical outcomes, procedures indicated, and subsequent corrective reoperations. Younger patients maintained greater physical function with comparable radiographic correction, with less frequent indication for tendon transfers, arthrodesis, and additional corrective surgeries. Level of Evidence: Level III, retrospective comparative study.

Abstract
PURPOSE The purpose of this study was to quantify limitations in sagittal ankle range of motion (ROM) at least two years after lateral column lengthening osteotomy of the calcaneus (LLC) and their implications regarding quality of life. METHODS Fifteen patients with a mean follow-up of 80 ± 27 months after LLC and 15 age-matched healthy persons participated in this study. Ankle joint complex ROM in plantarflexion and dorsiflexion was measured bilaterally using a goniometer and fluoroscopy (patients only). Quality of life was assessed using the short-form health questionnaire (SF36). Differences in ROM parameters (for the tibiotalar and subtalar joint) between sides (affected vs. unaffected) and between groups (patient vs. controls) and the relationship between ROM parameters and quality of life scores were assessed. RESULTS ROM of the ankle joint complex on the affected side in patients was smaller than on the contralateral side (goniometer and fluoroscopy) and in healthy persons (goniometer; all P < .05). Among patients, SF36 total and pain scores, respectively, correlated with ROM of the subtalar joint (fluoroscopy; R = 0.379, P = 0.039 and R = 0.537, P = 0.001). Among patients and healthy persons, those with smaller dorsiflexion (goniometer) had lower quality of life scores. CONCLUSIONS The smaller sagittal ROM of the affected ankle joint complex compared with the contralateral foot and healthy controls was mainly explained by limitations in the tibiotalar joint. Because of its association with quality of life, ROM should be considered in the treatment and rehabilitation planning in patients who are candidates for LLC.

Abstract
BACKGROUND The Evans osteotomy is a widely used procedure for the correction of adult and pediatric flexible flatfoot deformity. Locking plates are commonly used to stabilize the osteotomy and the allograft. However, there have been incidences of soft-tissue irritation caused by the hardware, requiring subsequent hardware removal. Therefore, we sought to review whether age, sex, or laterality of the procedure had any correlation with the rate of hardware removal. METHODS A retrospective review was performed of 47 consecutive patients who underwent an Evans calcaneal osteotomy between October 1, 2013, and October 1, 2016. Data were collected and analyzed based on age, sex, laterality, and the need for hardware removal. RESULTS All of the 47 patients met the inclusion criteria. Seventy procedures were performed, and hardware removal was required in 16 patients and 21 feet (30%). The only statistically significant finding was that 11 females and only five males required either unilateral or bilateral hardware removal (P = .039). All 16 patients reported complete pain relief after hardware removal. CONCLUSIONS Females are twice as likely as males to develop symptoms after locking plate application over an Evans osteotomy and may require hardware removal. Despite the low-profile nature of the locking plate to fixate the Evans osteotomy, the hardware can be a source of significant pain. Patients, especially females, should be cautioned about potential hardware-related pain and a possible follow-up procedure to remove the hardware.

Abstract
Reconstruction of the flexible adult-acquired flatfoot deformity (AAFD) is controversial, and numerous procedures are frequently used in combination, including flexor digitorum longus transfer, medializing calcaneal osteotomy (MCO), heel cord lengthening/gastrocnemius recession, lateral column lengthening (LCL), Cotton osteotomy or first tarsometatarsal fusion, and spring ligament reconstruction. This article summarizes recent studies demonstrating that patients have significant improvements after operative treatment of flexible AAFD. It reviews current literature on clinical and radiographic outcomes of the MCO, LCL, and Cotton osteotomies. The authors describe how this information can be used in surgical decision making in order to tailor operative treatment to an individual patient's deformity.

Abstract
BACKGROUND Evans (E) and Hintermann (H) lateral lengthening calcaneal osteotomies (LLCOTs) are commonly used to correct flexible flatfoot deformities. Both methods are well accepted and produce good clinical results. The aim of this study was to compare the postoperative outcomes of both osteotomies. METHODS We retrospectively examined 53 patients with flatfoot deformities, who received surgery between October 2008 and March 2014. Seventeen E-LLCOT and 36 H-LLCOT procedures were performed during this time period, with a mean follow-up of 67.7 ± 20.6 and 40 ± 12.9 months, respectively. Data were collected using clinical and radiological examination, as well as clinical scores (Foot and Ankle Outcome Score [FAOS], University of California at Los Angeles [UCLA] activity score, numerical rating scale [NRS], and the Short-Form 36-item Health Survey [SF-36]) during regular follow-up. RESULTS For both groups of patients, the FAOS score, pain-NRS, and SF-36 improved significantly following surgery ( P < .05). The talus-second metatarsal angle, talonavicular coverage, and naviculocuneiform overlap showed significant correction ( P < .05). Postoperatively, radiographic degenerative changes were detected in the calcaneocuboid (CC) and subtalar joint in both groups of patients: 41% and 18% after E-LLCOT compared with 25% and 14% after H-LLCOT, although these changes did not have any clinical relevance ( P < .05). No secondary arthrodesis was necessary. There were no significant differences in the clinical or radiological outcome parameters when compared between the 2 groups. CONCLUSION Both surgical techniques resulted in a significant improvement of clinical outcome scores and led to good radiological correction of flatfoot deformities. It appears that the CC joint develops less degenerative changes following the H-LLCOT procedure. LEVEL OF EVIDENCE Level III, comparative series.

Abstract
BACKGROUND: Lateral column lengthening and plantarflexion dorsal opening wedge osteotomy of the medial cuneiform are 2 commonly used procedures to address the deformity seen in severe flexible pes planovalgus deformity. Traditionally, iliac crest allograft or autograft has been used to fill the osteotomy sites. Porous metallic wedges can be used as an alternative to avoid the concerns associated with both autograft and allograft. METHODS: We performed a retrospective review of patients who had corrective osteotomies utilizing metallic wedges to address flexible pes planovalgus with at least 2 years of follow-up data. Preoperative radiographic measurements (anteroposterior [AP] and talo-first metatarsal angle, calcaneal pitch, talocalcaneal angle, and talonavicular uncoverage angle) and functional scores (visual analog scale [VAS] pain, Foot and Ankle Ability Measure [FAAM] Activities of Daily Living [ADL], FAAM Sports) were compared to postoperative radiographic measurements and functional scores. RESULTS: There were statistically significant improvements in all radiographic parameters and functional scores. Two nonunions were seen, one of which healed with revision surgery while the other was asymptomatic. At the time of last radiographic follow-up, there were no recurrences of deformity or collapse. CONCLUSION: Porous metallic wedges offer an attractive alternative to autograft and/or allograft in the setting of corrective osteotomies for severe flexible pes planovalgus. Patients who underwent corrective osteotomies using these wedges demonstrated reliable, effective, and stable radiographic correction as well as significant improvements in function and pain.

Abstract
BACKGROUND Reconstruction of the stage II adult-acquired flatfoot deformity (AAFD) often requires the use of multiple osteotomies and soft tissue procedures that may not heal well in older patients. The purpose of our study was to determine whether patients older than 65 years with stage II AAFD had inferior clinical outcomes or an increased number of subsequent surgical procedures after flatfoot reconstruction when compared with younger patients. METHODS One-hundred forty consecutive feet (70 right, 70 left) with stage II AAFD in 137 patients were divided into 3 groups based on age: younger than 45 years (young; n = 21), 45 to 65 years (middle-aged; n = 87), and 65 years and older (older; n = 32). Preoperative and postoperative Foot and Ankle Outcome Scores (FAOSs) at a minimum of 2 years were compared. Hospital records were reviewed to determine if patients underwent a subsequent procedure postoperatively. RESULTS Patients in the older group did not demonstrate any differences in changes in FAOS subscales compared with patients in the young and middle-aged groups (all P > .15). The older group had significant preoperative to postoperative improvements in all the FAOS subgroups ( P < .01). In addition, patients in the older group were not more likely to undergo a subsequent surgery than were the younger patients (all P > .10). CONCLUSIONS Our study found that patients older than 65 years with stage II AAFD have improvements in patient-reported outcomes and rates of revision surgery after surgical reconstruction that were not significantly different than those of younger patients.

Abstract
Background The timing and strategy of treatment for flatfoot still remain controversial. It is a difficult problem when facing severe adolescent flexible flatfoot because a single procedure cannot realign flatfoot deformity effectively. Methods We reviewed 13 adolescent flexible flatfoot patients who underwent double calcaneal osteotomy during May 2012 to June 2015. The mean age of patients was 15.2 ± 1.8 (range, 10–18) years. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot (AOFAS-AH) scores and SF-36 score were adopted to evaluate the preoperative and postoperative functions of the foot. Changes of hindfoot valgus angles, talonavicular uncoverage angles on AP view and talo-first metatarsal angles, and talar pitch angles and calcaneal pitch angles on the lateral film before and after surgery were measured. Results All 13 patients (15 ft) were followed. The mean duration of follow-up was 34.5 ± 15.7 (range, 21–60) months. The hindfoot valgus angle improved from 16.5 ± 4.1 to 2.9 ± 1.6. On the foot AP view, the mean preoperative and postoperative talonavicular coverage angles were 24.9 ± 8.5 and 6.5 ± 3.6. On the lateral view of the foot, the average preoperative and postoperative talo-first metatarsal angles were 18.1 ± 5.5 and 4.9 ± 4.4. The mean preoperative and postoperative talar pitch angles were 36.4 ± 4.7 and 24.0 ± 5.6. The AOFAS-AH score improved from 68.9 ± 12.3 preoperatively to 94.6 ± 3.9 postoperatively. Conclusion With additional procedures, double calcaneal osteotomy was an effective method for severe adolescent flexible flatfoot.

Abstract
Lateral column lengthening osteotomy is very useful surgical technique in treating stage II of pes planovalgus deformity of the foot. Either autograft from the iliac crest or allograft can be used for this purpose. In our technique we describe a novel method of obtaining bone graft locally from the calcaneus and therefore avoiding complications and morbidity associated with iliac crest graft.

Abstract
BACKGROUND Adult acquired flatfoot deformity is a commonly seen condition with a large clinical spectrum. It ranges from asymptomatic subjects to severely disabled arthritic patients. Posterior tibialis tendon dysfunction is a common cause of adult acquired flatfoot deformity. METHODS This article systematically reviews the published literature from books and journals that were either originally written or later translated into the English language regarding the subject of posterior tibialis tendon dysfunction. RESULTS Posterior tibialis tendon dysfunction is a primary soft tissue tendinopathy of the posterior tibialis that leads to altered foot biomechanics. Although the natural history of posterior tibialis tendon dysfunction is not fully known, it has mostly been agreed that it is a progressive disorder. While clinical examination is important in diagnosing adult acquired flat-feet; further investigation is often required to delineate the different aetiologies and stage of the disease. The literature describes many different management choices for the different stages of posterior tibialis tendon dysfunction. CONCLUSION Because of the wide range of symptom and deformity severity, surgical reconstruction is based on a-la-carte. The consensus is that a plethora of reconstructive options needs to be available and the list of procedures should be tailored to tackle the different symptoms, especially when managing complex multi-planar reconstructions.

Abstract
INTRODUCTION Koutsogiannis' osteotomy has been widely described to treat adult-acquired flatfoot. However, few articles describe its midterm follow-up. Our aim was to study clinical and radiological outcomes at least one year after surgery and to analyze whether a combined procedure on the medial soft tissue affected these outcomes. METHODS We performed a retrospective study of 30 feet of patients who underwent a Koutsogiannis' osteotomy due to adult-acquired flatfoot stage II and "early stage III": a stage III acquired flatfoot without any important structural deformities. The parameters studied were additional medial soft tissue procedures, clinical outcome through the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and midfoot score as well as complications and radiological measurements. RESULTS Sixteen cases were "early stage III" and 14 stage II. Thirteen patients underwent an associated posterior tibial tendon (PTT) revision: in three cases an end-to-end suture was possible, seven cases needed a FDL transposition, and three underwent synovectomy. Statistically significant improvement was found in the AOFAS score although no significant changes were seen radiologically. No additional benefit was found with the revision of the posterior tibial tendon. As to clinical and radiological results, no differences were found between stage II and "early stage III". Five cases presented a mild dysesthesia but only one patient needed neurolysis. CONCLUSIONS We consider the Koutsogiannis' osteotomy to be a safe and effective procedure to reduce pain in patients with stage II and "early stage III" adult-acquired flatfoot.

Abstract
BACKGROUND While previous work has demonstrated a linear relationship between the amount of medializing calcaneal osteotomy (MCO) and the change in radiographic hindfoot alignment following reconstruction, an ideal postoperative hindfoot alignment has yet to be reported. The aim of this study was to identify an optimal postoperative hindfoot alignment by correlating radiographic alignment with patient outcomes. METHODS Fifty-five feet in 55 patients underwent flatfoot reconstruction for stage II adult-acquired flatfoot deformity (AAFD) by 2 fellowship-trained foot and ankle orthopedic surgeons. Hindfoot alignment was determined as previously described by Saltzman and el-Khoury.(23) Changes in pre- and postoperative scores in each Foot and Ankle Outcome Score (FAOS) subscale were calculated for patients in postoperative hindfoot valgus (≥0 mm valgus, n = 18), mild varus (>0 to 5 mm varus, n = 17), and moderate varus (>5 mm varus, n = 20). Analysis of variance and post hoc Tukey's tests were used to compare the change in FAOS results between these 3 groups. RESULTS At 22 months or more postoperatively, patients corrected to mild hindfoot varus showed a significantly greater improvement in the FAOS Pain subscale compared with patients in valgus (P = .04) and the Symptoms subscale compared with patients in moderate varus (P = .03). Although mild hindfoot varus did not differ significantly from moderate varus or valgus in the other subscales, mild hindfoot varus did not perform worse than these alignments in any FAOS subscale. No statistically significant correlations between intraoperative MCO slide distances and FAOS subscales were found. CONCLUSIONS Our study indicates that correction of hindfoot alignment to between 0 and 5 mm of varus on the hindfoot alignment view (clinically a straight heel) following stage II flatfoot reconstruction was associated with the greatest improvement in clinical outcomes following hindfoot reconstruction in stage II AAFD.

Abstract
BACKGROUND Anatomy of the medial collateral and spring ligament complexes has been the cause of confusion. The anatomic description is highly dependent on the source studied and little agreement exists between texts. In addition, inconsistent nomenclature has been used to describe the components. This study attempted to clarify confusion through the creation of a 3D ligament map using attachment-based dissection. METHODS Nine fresh foot and ankle specimens were observed. The medial collateral ligament and spring ligament complexes were dissected using their attachment sites as a guide to define individual components. Each component's perimeter and thickness was measured and each bony attachment was mapped using a microscribe 3D digitizer. RESULTS Five components were identified contributing to the ligament complexes of interest: the tibiocalcaneonavicular, superficial posterior tibiotalar, deep posterior tibiotalar, deep anterior tibiotalar, and inferoplantar longitudinal ligaments. The largest component by total attachment area was the tibiocalcaneonavicular ligament followed by the deep posterior tibiotalar ligament. The largest ligament surface area of attachment to the tibia and talus was the deep posterior tibiotalar ligament. The largest attachment to the navicular and calcaneus was the tibiocalcaneonavicular ligament, which appeared to function in holding these bones in proximity while supporting the head of the talus. CONCLUSION By defining complex components by their attachment sites, a novel, more functional and reproducible description of the medial collateral and spring ligament complexes was created. CLINICAL RELEVANCE The linear measurements and 3D maps may prove useful when attempting more anatomically accurate reconstructions.

Abstract
BACKGROUND The calcaneal displacement osteotomy is frequently used by foot and ankle surgeons to correct hindfoot angular deformity. Headed compression screws are often used for this purpose, but a common complication is postoperative plantar heel pain from prominent hardware. We evaluated hardware removal rates after calcaneal displacement osteotomies and analyzed technical factors including screw size, position, and angle. We hypothesized that larger screws placed more plantarly would have been removed more frequently. We also believed that although 2 smaller screws cost more initially, when removal rates and cost are accounted for, savings would be demonstrated with this technique. METHODS We retrospectively collected data on type of fixation, cost of fixation, and frequency of removal. After exclusions we had 30 patients in our screw removal cohort and 119 in our screws retained cohort. A basic cost analysis and statistical analysis was performed. RESULTS The small screw group had a hardware removal rate of 9% (4/43) compared to 25% (26/104) of the larger screw group (P = .032). While the cost of 2 smaller screws is more than that of 1 larger screw, when the cost of removal and the rates of doing so are considered, the smaller screws resulted in substantial cost savings. CONCLUSION Technical considerations for the medial displacement calcaneal osteotomy, including the use of multiple smaller screws, provided for a lower rate of hardware removal and likely decreased long-term costs.

Abstract
BACKGROUND The calcaneal displacement osteotomy is a procedure frequently used by foot and ankle surgeons for hindfoot angular deformity. Traditional techniques use compression screw fixation that can result in prominent hardware. While the results of the procedure are generally good, a common concern is the development of plantar heel pain related to prominent hardware. The primary purpose of this study is to retrospectively compare clinical outcomes of 2 fixation methods for the osteotomy. Secondarily a cost analysis will compare implant costs to hardware removal costs. METHODS Records were reviewed for patients who had undergone a calcaneal displacement osteotomy fixated with either lag screw or a locked lateral compression plate (LLCP). Neuropathy, previous ipsilateral calcaneus surgery, heel pad trauma, or incomplete radiographic follow-up were exclusionary. RESULTS Thirty-two patients (19.4%) required hardware removal from the screw fixation group compared to 1 (1.6%) of the LLCP group, which is significant (P < .05). Time to radiographic healing was not significantly different (P = .87). The screw fixation group required more follow-up visits over a longer period of time (P < .05). Implant cost was remarkably different with screw fixation costing on average $247.12, compared to the LLCP costing $1175.59. Although the LLCP cost was significantly higher, cost savings were identified when the cost of removal and removal rates were included. CONCLUSION This study demonstrates that this device provides adequate stabilization for healing in equivalent time to screw fixation. The LLCP required decreased rates of hardware removal with fewer postoperative visits over a shorter period of time. Significant savings were demonstrated in the LLCP group despite the higher implant cost. LEVELS OF EVIDENCE Therapeutic, Level III, Retrospective Comparative Study.

Abstract
BACKGROUND The prevalence of tibialis posterior tendon dysfunction (PTTD) is estimated to be as high as 3% to 4% in Western populations, and it is one of the most commonly misdiagnosed conditions of the foot and ankle. METHODS Clinical and radiological outcomes were assessed in grade IIB PTTD treated with a medializing calcaneal osteotomy, lateral column lengthening, flexor digitorum longus transfer, and tendo-Achilles lengthening. The clinical and radiological findings recorded were the SF-36 score on physical function and mental health, midfoot and hindfoot American Orthopaedic Foot and Ankle Society (AOFAS) clinical scores, the midfoot and visual analog pain scores, as well as the radiological measurements of the hindfoot calcaneal pitch, talo-first metatarsal angle, and medial cuneiform height. The time points of assessment were preoperatively, 6 months postoperatively, and 24 months postoperatively by an examiner different from the operating surgeon. RESULTS The SF-36 score on physical function (mean difference of 8.7 and 8.2, respectively), AOFAS midfoot score (mean difference of 29.6 and 15.3, respectively), AOFAS ankle-hindfoot score (mean difference of 23.2 and 14.3, respectively), midfoot visual analog pain score (mean difference of 4.0 and 1.2), and the ankle and hindfoot visual analog score (mean difference of 3.6 and 1.6) all had significant reduction from the preoperative to the 24-month postoperative time point (P < .001). Radiologically, there was also correction of the deformity associated with PTTD. The hindfoot calcaneal pitch was corrected from 8.4 degrees to 18.7 degrees. The talo-first metatarsal angle was corrected from 14.0 degrees to 1.3 degrees, and the medial cuneiform height was corrected from 10.3 mm to 20.4 mm at 24 months postoperatively. CONCLUSION Grade IIB PTTD treated with a medializing calcaneal osteotomy, lateral column lengthening, flexor digitorum longus transfer, and tendo-Achilles lengthening demonstrated statistical significant improvement in hindfoot and midfoot AOFAS scores, SF-36 physical function scores, as well as visual analog scores. The complications were minimal. We advocate the combination of these procedures as being successful for the treatment of grade IIB PTTD. Longer term follow-up is needed to determine if these improvements plateau, improve, or deteriorate. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
An inappropriately positioned skin incision for medial displacement calcaneal osteotomy can put the sural nerve at risk; however, unanimous agreement has not been reached about the optimal strategy for making this incision. In the present cadaveric study, 20 cadaveric specimens were dissected to describe the anatomic course of the sural nerve within the operative area and to provide a more practical reference for surgeons to make a safe incision. The following points were used in the analyses: point A, the tip of the lateral malleolus; point B, the inferior margin of the calcaneus on the plumb line through point A; point C, the posteroinferior margin of the calcaneus; and point D, the lateral border of the Achilles tendon on the same level (collinear) with point A. With careful dissection, the distances of the sural nerve to points A and B in the vertical direction (lines D1 and D2, respectively), to points A and C in the diagonal direction (lines D3 and D4, respectively), and to points A and D in the horizontal direction (lines D5 and D6, respectively) were measured. The landmarks were identified and the distances measured by 3 independent researchers. The median ratio of D1 to D1+D2, D3 to D3+D4, and D5 to D5+D6 was 0.36 (range 0.20 to 0.47), 0.26 (range 0.19 to 0.32), and 0.43 (range 0.34 to 0.52), respectively. Accordingly, we believe it is relatively safe to make an oblique incision that runs through the point that is no less than one third of the distance from the tip of the lateral malleolus to the posteroinferior margin of the calcaneus.

Abstract
BACKGROUND Options for surgical correction of acquired flexible flatfoot deformity involve bone and soft-tissue reconstruction. We used an advanced cadaver model to evaluate the ability of key surgical procedures to correct the deformity and to resist subsequent loss of correction. METHODS Stage-IIB flatfoot deformity was created in ten cadaver feet through ligament sectioning and repetitive loading. Six corrective procedures were evaluated: (1) lateral column lengthening, (2) medial displacement calcaneal osteotomy with flexor digitorum longus transfer, (3) Treatment 2 plus lateral column lengthening, (4) Treatment 3 plus "pants-over-vest" spring ligament repair, (5) Treatment 3 plus spring ligament repair with use of the distal posterior tibialis stump, and (6) Treatment 3 plus spring ligament repair with suture and anchor. Correction of metatarsal dorsiflexion and of navicular eversion were quantified initially and periodically during postoperative cyclic loading. RESULTS Metatarsal dorsiflexion induced by arch flattening was initially corrected by 5.5° to 10.6°, depending on the procedure. Navicular eversion was initially reduced by 2.1° to 7.7°. The correction afforded by Treatments 1, 3, 4, 5, and 6 exceeded that of Treatment 2 initially and throughout postoperative loading. Inclusion of spring ligament repair did not significantly enhance correction. CONCLUSIONS Under the tested conditions, medial displacement calcaneal osteotomy with flexor digitorum longus tendon transfer was inferior to the other evaluated treatments for stage-IIB deformity. Procedures incorporating lateral column lengthening provided the most sagittal and coronal midfoot deformity correction. Addition of spring ligament repair to a combination of these three procedures did not substantially improve correction. CLINICAL RELEVANCE An understanding of treatment effectiveness is essential for optimizing operative management of symptomatic flatfoot deformity. This study provides empirical evidence of the advantage of lateral column lengthening and novel information on resistance to postoperative loss of correction.

Abstract
Tendon transfers are critical to successful surgical correction of adult flexible flatfoot deformity and may be beneficial in correcting rigid deformities as well. Patients with refractory stage I and II deformities often require selective osteotomies in addition to tendon transfer. Patients with stage III and IV deformities typically require hindfoot arthrodesis. One of several tendons can be used for transfer based on surgeon's preference. Flexor digitorum longus (FDL) and flexor hallucis longus (FHL) transfers have been shown to have good results. A peroneus brevis transfer is typically used to supplement small FDL or FHL transfer donors or in revision cases.

Abstract
BACKGROUND Lateral column lengthening procedures have been extensively reported either as primary procedures or adjuncts to combined soft tissue procedures and osteotomies for the correction of the pes planovalgus deformity. There is also considerable debate as to the ideal procedure that is not followed by recurrence and obviates the need for revision surgeries and minimizes complications. We describe a technique and present the clinical results of lateral column lengthening that provides a powerful correction to restore normal foot alignment. METHODS We retrospectively reviewed 26 feet in 21 patients with a mean age of 35.4 years (range, 12-75) over an average follow-up period of 71 months (range, 12-147) who underwent reconstructive surgery for flexible pes planovalgus foot. The reconstructive procedures included a central calcaneal osteotomy in all patients, a medial column stabilization procedure, flexor digitorium transfer (FDL), and a gastrocnemius or Achilles tendon lengthening. Clinical evaluation was carried out with the AOFAS ankle-hindfoot scores. Standard weight-bearing anterior posterior (AP) and lateral radiographs before surgery and at follow-up were analyzed for radiographic parameters of correction. RESULTS The median AOFAS score increased from 50 to 90. Two patients reported dissatisfaction with the result. There were no nonunions nor complications related to hardware. Radiographic improvement of the talonavicular coverage angle was a 74% change from baseline value. All radiographic parameters improved (P < .001) except the lateral talocalcaneal angle (P = .48). No secondary subsidence of the arch was observed within the follow-up time. CONCLUSION Correction of flexible pes planovalgus deformity with a central calcaneal osteotomy was an effective, reproducible method to restore normal foot alignment and good function.

Abstract
PURPOSE At the beginning of the twenty-first century, the computer has supplemented the possibilities of orthopaedic surgery. This article analyses the feasibility and potential clinical benefit of intraoperative three-dimensional imaging (3D), computer assisted surgery (CAS) and intraoperative pedography (IP) in foot and ankle surgery. METHODS The feasibility, accuracy and clinical benefit of 3D, CAS and IP were analysed in ongoing experimental and prospective studies at the institution in which the inventor of IP and principal user of 3D and CAS in foot and ankle surgery operates. RESULTS Three dimensional imaging: In approximately one third of the cases, reduction/correction and/or implant position was corrected after intraoperative 3D scan during the same procedure in different prospective, consecutive, non-controlled studies (Level III). CAS: CAS guidance for the correction of deformities of the ankle, hindfoot and midfoot/tarsometatarsal (TMT) joint provided higher accuracy, a faster correction process and better scores at a minimum follow-up of two years in comparison without CAS guidance in a single-centre matched-pair follow-up study (Level II). IP: Additional use of IP as the only difference between two groups with correction and/or arthrodesis at foot and/or ankle led to improved clinical outcome scores at a mean of two years follow-up in a prospective randomised controlled study (Level I). CONCLUSIONS Three dimensional imaging provides important information which could not be obtained from two-dimensional C-arm alone. The benefit of CAS is high when improved accuracy may lead to an improved clinical outcome. Intraoperative pedography is useful when intraoperative biomechanical assessment may lead to an immediate improvement of the achieved surgical result.

Abstract
Lengthening osteotomy of the calcaneus (LO) and flexor digitorum longus tendon (FDL) transfer to the navicular is one option for the treatment of flexible flatfoot deformity (FD). The aim of the study was to analyse the amount of correction and clinical outcome including pedographic assessment. In a prospective consecutive non-controlled clinical followup study, all patients with FD that were treated with LO and FDL from September 1st 2006 to August 31st, 2009 were included. Assessment was performed before surgery and at 2-year-followup including clinical examination (with staging of posterior tibialis insufficiency) weight bearing radiographs (Talo-1st metatarsal angles (TMT)), pedography (increased midfoot contact area and force) and Visual Analogue Scale Foot and Ankle (VAS FA). 112 feet in 102 patients were analysed (age, 57.6 (13-82), 42% male). In 12 feet (9%) wound healing delay without further surgical measures was registered. All patients achieved full weight bearing during the 7th postoperative week. Until followup, revision surgery was done in 3 patients (fusion calcaneocuboid joint (n=2), correction triple arthrodesis (n=1)). 101 feet (90%) completed 2-year-followup. TMT dorsoplantar/lateral/Index and VAS FA scores were increased, and posterior tibialis insufficiency stage, pedographic midfoot contact area and force percentage were decreased (each p<.05). All relevant parameters (stage of posterior tibialis insufficiency, TMT angles and Index, pedographic midfoot contact area and force percentage, VAS FA) were improved 2 years after LO and FDL transfer to the navicular in FD. The complication rate was low. This method allows safe and predictable correction.

Abstract
BACKGROUND There are various methods available to fix a calcaneal osteotomy, ranging from screws to plates and staples. It is not clear if one method is superior to the other. In this series we compare the complications and union rates of 3 different methods of fixation. METHODS A retrospective review of the records of a consecutive series of patients who had a calcaneal osteotomy was undertaken. All patients had their osteotomy by the same technique, however the subsequent fixation was performed using 3 different methods: a lateral locking plate, a headless, or a headed screw. The screws were placed through a separate stab incision inserted from the infero-posterior heel. Records were kept of subsequent symptoms from the hardware and need for hardware removal as well as any complications. When screws were inserted, the entry point in relation to the weight-bearing surface of the calcaneus was also recorded. Sixty-seven osteotomies were investigated, of which 17 were fixed using a headed screw, 18 using a headless screw, and the remaining 32 were fixed using a lateral plate. RESULTS There was an overall 97% union rate. The only 2 cases of delayed union were both fixed using a lateral plate. Overall, 47% of the headed screws, 11% of the headless screws, and 6% of the lateral plates were removed to address symptoms that were suspected to arise from the hardware. There was a 10% rate of wound complication in the lateral plate cohort. There were no cases of sural nerve injury or neuroma. No correlation was found between entry position of screw and subsequent hardware symptoms. CONCLUSIONS Calcaneal osteotomies have high union rates regardless of fixation method. Fixation using a headed screw is associated with a high rate of secondary screw removal. This was unrelated to the position of the screw in relation to the weight-bearing surface of the calcaneus in our series. Hardware problems were less frequent in the headless screw or the lateral plate groups; however, the incidence of local wound complications and radiological delayed union was higher in the group fixed with a lateral plate. This may be related to the greater soft tissue dissection and lesser compression achieved at the osteotomy site. LEVEL OF EVIDENCE Level III, retrospective case control study.

Abstract
BACKGROUND Successful correction of hindfoot alignment in adult acquired flatfoot deformity (AAFD) is likely influenced by the degree of medializing calcaneal osteotomy (MCO) performed, but it is not known if other reconstruction procedures significantly contribute as well. The purpose of this study was to evaluate the correlation between common preoperative and postoperative variables and hindfoot alignment. METHODS Thirty patients with stage II AAFD undergoing flatfoot reconstruction were followed prospectively. Preoperative and postoperative radiographs were reviewed to assess for correction in hindfoot alignment as measured by the change in hindfoot moment arm. Nineteen variables were analyzed, including age, gender, height, weight, body mass index (BMI), medial cuneiform-fifth metatarsal height, anteroposterior (AP) talonavicular coverage, AP talus-first metatarsal, lateral talus-first metatarsal and calcaneal pitch angles as well as intraoperative use of the MCO, lateral column lengthening (LCL), Cotton osteotomy, first tarsometatarsal fusion, flexor digitorum longus transfer, spring ligament reconstruction, and gastrocnemius recession or Achilles lengthening. Mean age was 57.3 years (range, 22-77). Final radiographs were obtained at a mean of 47 weeks (range, 25-78) postoperatively. RESULTS Seven variables were found to significantly affect hindfoot moment arm. These were gender (P < .05), the amount of MCO performed (P < .001), LCL (P < .01), first tarsometatarsal fusion (P < .01), spring ligament reconstruction (P < .01), medial cuneiform-fifth metatarsal height (P < .001), and calcaneal pitch angle (P < .05). Multivariate regression analysis revealed that MCO was the only significant predictor of hindfoot moment arm. The final regression model for MCO showed a good fit (R(2) = .93, P < .001). CONCLUSION Correction of hindfoot valgus alignment obtained in flatfoot reconstruction is primarily determined by the MCO procedure and can be modeled linearly. We believe that the hindfoot alignment view can serve as a valuable preoperative measurement to help surgeons adjust the proper amount of correction intraoperatively.

Abstract
The present multicenter, prospective study evaluated the subjective outcomes in patients after extraosseous talotarsal stabilization using the HyProCure(®) stent as a standalone procedure for the treatment of recurrent and/or partial talotarsal joint dislocation (RTTD) in a population of pediatric and adult patients. RTTD has been cited as a possible etiology for a number of foot ailments and might contribute to the development of pathologic features localized more proximally in the weightbearing musculoskeletal chain. Correction of RTTD might, therefore, lead to the reduction of pathologic features associated with this deformity. A total of 46 feet in 35 patients were included in the present investigation. Subjective evaluation used the Maryland Foot Score assessment, which was obtained preoperatively and 1, 2, and 3 weeks, 1, 2, 3, and 6 months, and 1 year postoperatively. The mean overall scores improved from a preoperative value of 69.53 ± 19.56 to a postoperative value of 89.17 ± 14.41 at the 1-year follow-up. Foot pain decreased by 36.97%, foot functional activities improved by 14.39%, and foot appearance improved by 29.49%. The greatest magnitude of improvement occurred 4 weeks postoperatively, with gradual improvement continuing through to the 1-year follow-up. Implants were removed from 2 patients (2 feet, 4.35%). No unresolved complications were observed. The positive subjective outcomes resulting from the extraosseous talotarsal stabilization procedure suggest that the intervention employing the device we have described alleviates pain and improves foot function and appearance in patients with RTTD.

Abstract
In summary, prior classifications have provided broad guidelines for treating the AAFF without accounting for case-specific variables in determining a treatment plan. The current system breaks down the deformity into three independent levels of involvement: the rearfoot, the ankle, and the midfoot. Via a simple, easy to remember, and reproducible schema based off the original Johnson and Strom classification, each level can be independently evaluated and a patient-specific surgical treatment plan can be formulated based on our most current understanding of the AAFF.

Abstract
Recurrent deformity in the adult flatfoot following previous tendon transfer represents a challenging treatment dilemma for even the most experienced foot and ankle surgeon. The evaluation must be comprehensive, resulting in a clear understanding of the extent to which previous surgical procedures either failed to address the deformity initially or led to progressive recurrence. Particularly in younger, more high-demand patients, every effort to preserve normal joint mechanics while alleviating pain and restoring functional alignment must be made. LCL coupled with MDCO and a comprehensive medial soft tissue reconstruction represents a joint-sparing modality for approaching even the most challenging flexible flatfoot deformities. Care to avoid overcorrection, particularly with a double calcaneal osteotomy, must be taken. In the presence of progressive degenerative changes or patient factors such as morbid obesity and advanced age, hindfoot arthrodesis, particularly realignment subtalar joint arthrodesis, provides a technically straightforward, predictable means of achieving a pain-free plantigrade foot. Talonavicular arthrodesis and double arthrodesis, although reliable means of achieving pain relief and functional alignment, do sacrifice considerably more hindfoot motion and are likely more appropriately reserved for elderly, low-demand patients or those with more severe fixed deformities.
