Minimally invasive surgery in medial displacement calcaneal osteotomy for acquired flatfoot deformity: a systematic review of the literature. Arch Orthop Trauma Surg 2024; 144:1139-1147. [PMID: 38212588 DOI: 10.1007/s00402-023-05188-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 12/19/2023] [Indexed: 01/13/2024]
Abstract
BACKGROUND Minimally invasive surgery (MIS) in medial displacement calcaneus osteotomy (MDCO) has been proposed for surgical correction of adult-acquired flat foot deformity (AAFD) to reduce complications of open approaches. The aim of our study is to systematically analyze complications and the clinical and radiological results of MIS- MDCO. METHODS A systematic review of the English literature was performed on 30th October 2023. Randomized controlled trials and non-randomized trials, cohort studies, case-control studies and case series concerning surgical correction of AAFD with MIS-MDCO and with at least 15 patients were included. Case reports, technical notes, animal or cadaveric studies were excluded. The quality and risk of bias of the studies included were evaluated using GRADE and MINORS systems. Complications rate, clinical and radiological results were inferred from the studies included. RESULTS Nine articles were included. A total of 501 cases treated with MIS-MDCO were analysed with a mean follow-up of 11.9 ± 5.1 months. The reported wound infection rate was about 3% and sural neuropathy was rated about 1%. Only 4% of the cases required removal of the screw for pain. In the comparative studies (MIS versus Open MDCO), comparable clinical results but with significant differences (P < 0.001) in infection rates (1% versus 14%) and sural neuropathy (2% versus 1%) were observed. CONCLUSION AAFD correction performed with MIS-MDCO, with the limitation of a poor quality and high risk of bias of the included studies, seems to provide good clinical results and high subjective satisfaction with a lower complication rate compared to open approach. Further high-quality long-term comparative studies could better clarify complications and clinical and radiological outcomes of the MIS technique in the treatment of AAFD. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Somatic nerve pain is one of the most common complications following surgery of the foot and ankle but may also arise following traumatic injury or chronic nerve compression. The sural nerve is a commonly affected nerve in the foot and ankle; it is at risk given the proximity to frequently used surgical approaches, exposure to crush injuries, and traction from severe ankle inversion injuries. The purpose of this study is to investigate the outcomes of sural nerve neurectomy with proximal implantation for sural neuromas (SN) and chronic sural neuritis (CSN). METHODS Patients that underwent neurectomy with proximal implantation (20 muscle, 1 adipose tissue) by 2 foot and ankle specialists for isolated SN- and CSN-related pain at a single tertiary institution were included. Demographic data, baseline outcomes including 36-Item Short Form Health Survey (SF-36), Foot and Ankle Ability Measure (FAAM), and visual analog scale (VAS) were recorded. Final follow-up questionnaires using Patient Reported Outcomes Measurement Information System (PROMIS) lower extremity function, pain interference (PI), and neuropathic pain quality, FAAM, and VAS were administered using REDCap. Perioperative factors including neuropathic medications, diagnostic injections, the use of collagen wraps, and perioperative ketamine were collected from the medical record. Descriptive statistics were performed and potential changes in patient-reported outcome measure scores were evaluated using Wilcoxon signed-rank tests. RESULTS The 21 patients meeting inclusion criteria for this study had a median age of 47 years (interquartile range [IQR], 43-49) and had median follow-up duration of 33.7 months (IQR, 4.5-47.6). Median FAAM activities of daily living score improved from 40.6 (38.7-50.7) preoperatively to 66.1 (53.6-83.3) postoperatively, P = .032. FAAM sports scores improved from 14.1 (7.8-21.9) to 41.1 (25.0-60.9) postoperatively, P = .002. VAS scores improved from a median of 9.0 (8.0-9.0) to 3.0 (3.0-6.0), P < .001. At final follow-up, patients reported PROMIS lower extremity function score median of 43.8 (35.6-54.9), PROMIS neuropathic pain quality score of 54.1 (43.6-61.6), and PROMIS PI of 57.7 (41.1-63.8). Patients with both anxiety and depression reported less improvement in pain and physical. Other perioperative factors lacked sufficient numbers for statistical analysis. CONCLUSION Sural nerve neurectomy and proximal implantation (20 muscle, 1 adipose) provided significant improvement in pain and function for patients with sural neuromas and chronic sural neuritis at median follow-up of 33.7 months. Anxiety and depression were associated with significantly poorer outcomes following surgery. Patients with CRPS as well as recent nicotine use tended to report less improvement in pain and worse function after surgery, although this sample size was too limited for statistical analysis of these variables. Further research is needed to identify the ideal surgical candidates and perioperative factors to optimize patient outcomes. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Calcaneal osteotomy are used to treat various pathologies in the correction of hindfoot deformities. But lateral plantar artery (LPA) pseudoaneurysms have been reported following calcaneal osteotomy, and LPA pseudoaneurysms may be at risk for rupture. Although the vascular structures in close proximity to calcaneal osteotomies have variable courses and branching patterns, there is little information on safe zone for LPA during calcaneal osteotomy. The aims of this study were to identify the safety zone to avoid the LPA injury during calcaneal osteotomy. METHODS Enhanced computed tomography scans of 25 fresh cadaveric feet (male, n = 13; female, n = 12; mean age 79.0 years at the time of death) were assessed. The specimens were injected with barium via the external iliac artery. Line A is the landmark line and extends from the posterosuperior aspect of the calcaneal tuberosity to the plantar fascia origin, and the perpendicular distance between the LPA and line A at its closest point was measured on sagittal images. RESULTS The average perpendicular distance between the LPA and line A at its closest point was 15.2 ± 2.9 mm. In 2 cases (8.0 %), the perpendicular distance between the LPA and line A at its closest point was very close, approximately 9 mm. In 18 of 25 feet (72.0%), the point where perpendicular distance from the line A to LPA is the closest was the bifurcation of one of the medial calcaneal branches from LPA, and in 7 feet in 25 feet (28.0%) feet the point where perpendicular distance from the line A to LPA is the closest was the trifurcation of LPA, medial plantar artery, and one of the medial calcaneal branches. CONCLUSIONS Calcaneal osteotomy approximately more than 9 mm from the line A could injure the LPA in overpenetration into the medial aspect of tcalcaneal osteotomy. Completion of the osteotomy on the medial side should be performed with caution to avoid iatrogenic injury of the LPA. LEVELS OF EVIDENCE: Level IV, Cadaveric study.

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
Cavovarus deformity is a complicated condition most commonly resulting from neurologic, posttraumatic, or iatrogenic pathologic conditions. Careful evaluation of the cavovarus patient is necessary in determining appropriate treatment course. Weight-bearing radiographs are necessary, and advances in computed tomographic technology can be beneficial in identifying level of involvement. In the case of operative treatment of inframalleolar deformity, assessment of the subtalar joint position and relation of calcaneocuboid joint can be of assistance. Multiple osteotomies have been described providing uniplanar, biplanar, and triplanar correction and in the appropriate setting can prove beneficial to the surgeon in treating hind-foot cavovarus deformity.

The Effect of Gastrocnemius Recession and Tendo-Achilles Lengthening on Adult Acquired Flatfoot Deformity Surgery: A Systematic Review. J Foot Ankle Surg 2021; 59:1248-1253.

Abstract
The purpose of this study was to evaluate the available clinical and radiographic evidence for incorporation of a gastrocnemius recession or tendo-Achilles lengthening into the surgical correction of adult acquired flatfoot deformity. A systematic review of the literature was performed using PubMed, Embase, Cochrane, CINAHL, and Google Scholar. Among the relevant articles, the level of evidence and quality was identified using the Methodological Index for Non-Randomized Studies tool. No study explicitly examined whether clinical or radiographic outcomes after adult acquired flatfoot deformity correction are improved when incorporating a gastrocnemius recession or tendo-Achilles lengthening compared with when no such procedure is performed, nor have they directly compared outcomes between 2 procedures. Studies demonstrated an overall improvement in postoperative range of motion and plantar flexion power after gastrocnemius recession, but such findings are hard to separate from the clinical contribution of concomitant corrective procedures to the foot itself. All studies that analyzed anteroposterior talo-calcaneal angle, anteroposterior lateral talo-first metatarsal angle and calcaneal inclination angle revealed improvement of each parameter postoperatively. There were no high-level evidence studies in the literature explicitly quantifying ankle range of motion, plantar flexion power, or radiographic impact of gastrocnemius recession or tendo-Achilles lengthening on adult acquired flatfoot deformity correction. Although gastrocnemius-soleus complex contractures have certainly been demonstrated to coexist with adult acquired flatfoot deformity, support for lengthening procedures is largely based on expert opinion or case series and is difficult to distinguish from the clinical contribution of associated corrective procedures.

Abstract
PURPOSE Adult-acquired flatfoot deformity (AAFD) requires optimum planning that often requires several procedures for deformity correction. The objective of this study was to detect the difference between MDCO versus LCL in the management of AAFD with stage II tibialis posterior tendon dysfunction regarding functional, radiographic outcomes, efficacy in correction maintenance, and the incidence of complications. PATIENT AND METHODS 42 Patients (21 males and 21 females) with a mean age of 49.6 years (range 43-55), 22 patients had MDCO while 20 had LCL. Strayer procedure, spring ligament plication, and FDL transfer were done in all patients. Pre- and Postoperative (at 3 and 12 months) clinical assessment was done using AOFAS and FFI questionnaire. Six radiographic parameters were analyzed, Talo-navicular coverage and Talo-calcaneal angle in the AP view, Talo- first metatarsus angle, Talo-calcaneal angle and calcaneal inclination angle in lateral view and tibio-calcaneal angle in the axial view, complications were reported. RESULTS At 12 months, significant improvement in AOFAS and FFI scores from preoperative values with no significant difference between both groups. Postoperative significant improvements in all radiographic measurements in both groups were maintained at 12 months. However, the calcaneal pitch angle and the TNCA were better in the LCL at 12 months than MDCO, 17̊±2.8 versus 13.95̊±2.2 (p=0.001) and 13.70̊±2.2 versus 19.05̊±3.2 (p<0.001) respectively. 11 patients (26.2%) had metal removal, seven (16.6%) in the MDCO, and four (9.6%) in the LCL. Three (7.1%) in the LCL group had subtalar arthritis, only one required subtalar fusion. CONCLUSION LCL produced a greater change in the realignment of AAFD, maintained more of their initial correction, and were associated with a lower incidence of additional surgery than MDCO, however, a higher incidence of degenerative change in the hindfoot was observed with LCL.

Abstract
BACKGROUND Insertional Achilles tendinopathy (IAT) is a challenging common lower extremity disorder, despite several treatment options described in literature. Open dorsal closing wedge calcaneal osteotomy or Zadek Osteotomy (ZO), for the treatment of the IAT has good clinical results but a high rate of postoperative complications. The purpose of this study is to describe percutaneous ZO for the treatment of the IAT and to evaluate its impact on the clinical and functional postoperative outcomes. METHODS Twenty-six consecutive patients presenting with unilateral IAT refractory to nonoperative measures were treated with percutaneous ZO. Visual Analogue Scale (VAS) and Foot Function Index Score (FFI) were recorded preoperatively and at final follow-up visit (12±3) months. Postoperative complications, satisfaction, and relief of the pain were also recorded. RESULTS The percutaneous ZO showed a significant improvement (p<0.0001) in preoperative to postoperative FFI (from 65±9 to 8±12) and VAS (from 9±1 to 1±2). Two postoperative complications (8%) were observed: a case of symptomatic non-union and hardware pain, both in healthy patients. The overall rate of satisfaction after surgery was (92%). The relief from pain was achieved after an average period of 12 weeks. CONCLUSIONS ZO is a safe and effective procedure for the treatment of IAT. The use of a minimally invasive surgical approach is associated with excellent pain reduction (VAS score) and improved clinical function (FFI score). When compared to the open surgical approach, the percutaneous ZO may decrease recovery time and postoperative complications. LEVEL OF EVIDENCE III, retrospective case series.

Abstract
Surgical treatment of foot and ankle ailments is common, but in the past the choice of procedures was often dictated principally by positional considerations. This article reviews the use of the 2 primary biomechanical approaches, the kinematic and kinetic methods, and presents a novel unified method to guide surgical procedure choice, the kineticokinematic approach. Decision-making methods and resources are discussed and 2 case studies are presented to elucidate how this method may be used when choosing surgical procedures.

Abstract
Background The skin incision for medial displacement calcaneal osteotomy (MDCO) often damages the sural nerve. We aimed to identify the practical reference area in which the surgeon can incise the skin to minimize the injury of the sural nerve during MDCO. Methods The foot and ankles of 20 cadavers were dissected. The landmarks were the following four anatomical references: point A, the tip of the lateral malleolus; point B, the inferior margin of the calcaneus on the vertical line through point A; point C, the posteroinferior apex of the calcaneus; and point D, the lateral border of the Achilles tendon on the horizontal line through point A. The distances from 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. Results The median ratios of D1 to D1+D2, D3 to D3+D4, and D5 to D5+D6 were 0.34 (range 0.25 to 0.45), 0.23 (range 0.16 to 0.33), and 0.38 (range 0.26 to 0.50), respectively. Conclusions The distance ratios according to easily identifiable references would be a more practical incision strategy for surgeons to minimize sural nerve injury in both open and minimally invasive/percutaneous MDCO.

Abstract
BACKGROUND: Calcaneal osteotomies are often required in the correction of hindfoot deformities. The traditional open techniques, which include a lateral or oblique incision, are occasionally associated with wound healing problems and neurovascular injury. METHODS: A total of 122 consecutive patients who underwent a calcaneal osteotomy for hindfoot realignment treatment were included. Fifty-eight patients were operated using an open incision technique and 64 patients (66 feet) using a percutaneous technique. Clinical and radiologic assessments were performed preoperatively, at 6 weeks, and 1 year postoperatively. RESULTS: The American Orthopaedic Foot & Ankle Society scale scores and visual analog scale pain scores improved in both groups postoperatively. The difference between the groups was not significant. The results of the radiologic measurements pre- and postoperatively were not significantly different. No pseudarthrosis occurred in either group. The comparison of both groups showed a significantly lower risk for wound healing problems in the percutaneous group. The hospitalization time was significantly shorter in the percutaneous group. CONCLUSION: Because of the excellent results with the percutaneous calcaneal osteotomy, the authors feel encouraged to establish this procedure as a standard technique for calcaneus osteotomy, especially patients at high risk for wound healing problems. LEVEL OF EVIDENCE: Level III, comparative series.

[PMID: 30791933 PMCID: PMC6385451 DOI: 10.1186/s13018-019-1094-0] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 02/05/2019] [Indexed: 11/10/2022] Open
Abstract
Background Adult acquired flatfoot deformity (AAFD) represents a spectrum of deformities affecting the foot and the ankle. The optimal management of AAFD remains controversial. We evaluated the efficacy of surgical treatments of AAFD using both direct and indirect evidences. Methods We searched PubMed, EmBase, and the Cochrane Library to identify eligible studies conducted through November 2018. To compare different surgical strategies, we performed a network meta-analysis. A traditional meta-analysis using a random-effects model was used to evaluate the pooled outcome. Results A total of 21 studies including 498 patients were collected and analyzed. Network meta-analysis results based on lateral angle talocalcaneal-calcaneal pitch (LAT-CP) indicated that medial displacement calcaneal osteotomy (MDCO) has the highest probability to be the best course of AAFD treatment. However, analyses based on anteroposterior talo-first metatarsal (AP-TMT1) and lateral angle talocalcaneal talo-first metatarsal (LAT-TMT1) suggested that lateral column lengthening (LCL) was the best treatment, while those based on lateral angle talocalcaneal-arch height, anteroposterior talocalcaneal (AP-TC), lateral angle talocalcaneal-talocalcaneal (LAT-TC), anteroposterior-talonavicular coverage (AP-TNC), talonavicular coverage (TNC), and the American Orthopedic Foot and Ankle Society (AOFAS) indicated triple arthrodesis (TAO) as the best treatment. Moreover, double arthrodesis (DAO) provided the best treatment effect on the function score. Furthermore, according to traditional meta-analysis, the summary of standardized mean differences (SMD) indicated that the surgical interventions are associated with significant improvements in LAT-CP (SMD − 1.78), LAT-arch height (SMD − 4.95), AOFAS (SMD − 5.24), AP-TMT1 (SMD 2.45), LAT-TMT1 (SMD 1.97), AP-TC (SMD 3.05), LAT-TC (SMD 2.20), AP-TNC (SMD 2.07), TNC (SMD 1.70), and function score (SMD 0.95). Conclusions Our findings indicated that MDCO, LCL, TAO, or DAO might be the best surgical approaches for AAFD treatment. Furthermore, patients who received surgical interventions had significant improvements in symptoms and function.

Abstract
BACKGROUND A cadaveric and clinical study was performed to assess whether a minimally invasive technique is a potentially safer alternative compared to a calcaneal osteotomy through an open lateral approach. METHODS Cadaveric: A minimally invasive calcaneal osteotomy (MICO) was performed on nine cadaveric specimens. These were examined to identify any nerve injury and to quantify the displacement achieved with the osteotomy. Clinical: A retrospective review of a sequential case series of medializing MICO's performed by the senior author between October 2011 and November 2014 was undertaken. RESULTS Cadaveric: Neurological structures remained uninjured in all specimens. The distance of the sural nerve and the main trunk of the tibial nerve to the superior limb of the oblique osteotomy was 6.2±4.8mm (range 0-14mm) and 7.3±3.6mm (range 4-12mm), respectively. The mean coronal shift achieved was 16.7±3.4mm (range 12-21mm). Clinical: The senior author carried out 35 medializing MICO procedures. Radiological and clinical union occurred in all 35 cases (100%). There were no neurovascular or wound complications. CONCLUSION Minimally invasive calcaneal osteotomy offers a safe alternative to an open procedure with promising clinical results.

Abstract
Locking plate fixation is becoming more popular for fixation of lower extremity osteotomies. The present study evaluated locking plate fixation compared with screw fixation in the medial displacement calcaneal osteotomy procedure, measuring the outcomes and rate of hardware removal. The procedure was performed on 30 patients, 31 times, with 17 undergoing single screw fixation and 14 undergoing locking plate fixation. The return to activity was 6.87 ± 1.43 months, including some patients for whom running was their main activity. No malunions, nonunions, displacements, or infections developed. In 3 patients (21.4%), the locking plate was removed compared with 1 patient (5.9%) who required screw removal. The difference was not significant (p = .30). No differences were found in their postoperative American Orthopaedic Foot and Ankle Scale scores (91.9 ± 7.7 with plates versus 94.4 ± 5.8 with screws; p = .36). The Roles and Maudsley scores were the same in the 2 groups preoperatively at 4.0 ± 0.0, with the postoperative scores improving to 1.50 ± 0.5 and 1.41 ± 0.5 for the plate and screw group, respectively (p = .62). No significant increase was seen for patients undergoing hardware removal, regardless of the adjunctive procedure used (i.e., flexor digitorum longus/Kidner, Lapidus or midfoot fusion, subtalar arthroereisis, and endoscopic gastrocnemius recession). The stage of posterior tibialis dysfunction had no significant difference in the postoperative scores. From the results of the present study, we have concluded that using a locking plate or a single screw for fixation of the medial displacement calcaneal osteotomy provides acceptable patient outcomes and that the differences in the rate of hardware removal were not statistically significant between the 2 groups.

Abstract
BACKGROUND Calcaneal osteotomy is an established technique for correcting hindfoot deformity. Patients traditionally receive an osteotomy through the open lateral approach to the calcaneus. To reduce the rate of wound complications associated with a direct open lateral approach, a minimally invasive surgical (MIS) technique has been adopted. This uses a low-speed, high-torque burr to perform the same osteotomy under radiographic guidance. We hypothesized that the new MIS calcaneal osteotomy would be a safe alternative to open calcaneal osteotomy while obtaining the same displacement. METHODS The safety of the new MIS technique was investigated with a case controlled study on all patients who underwent displacement calcaneal osteotomy at the Nuffield Orthopaedic Centre from 2008 to 2014. The primary outcome measure was 30 day postoperative complication rate. Secondary outcome measures included operating time, duration of stay, fusion rates, and calcaneal displacement. Eighty-one patients underwent calcaneal osteotomy as part of their corrective surgery, 50 in the Open approach group and 31 in MIS group. The average age was 47.7 years (range 16-77) for the Open group and 50.1 (range 21-77) in the MIS group. RESULTS A mean calcaneal displacement of 9.4 mm (SD = 1.16, 8 to 11 mm) and 10.2 mm (SD = 1.06, 8 to 13 mm) was achieved through the MIS and Open approaches, respectively. There were significantly fewer wound complications in the MIS group (6.45%) compared to the Open group (28%, P = .022). The MIS group was associated with significantly lower rate of wound infection (3% versus 20%, P = .044). Three patients in the Open group experienced sural peripheral neuropathy. The average length of stay was 3.8 days following MIS and 4.3 days following open calcaneal osteotomy. Nonunion occurred in only 1 patient in the MIS group and none in the open group. CONCLUSIONS MIS calcaneal osteotomy was found to be a safe technique. It was technically as effective as calcaneal osteotomy performed through an open lateral approach but was associated with significantly fewer wound complications and fewer nerve complications. LEVEL OF EVIDENCE Level III, comparative study.

Abstract
Adult acquired flatfoot deformity is a progressive disorder with multiple symptoms and degrees of deformity. Stage II adult acquired flatfoot can be divided into stage IIA and IIB based on severity of deformity. Surgical procedures should be chosen based on severity as well as location of the flatfoot deformity. Care must be taken not to overcorrect the flatfoot deformity so as to decrease the possibility of lateral column overload as well as stiffness.

Abstract
We investigated the clinical outcomes after medial displacement calcaneal osteotomy with reconstruction of the posterior tibial tendon insertion on the navicular, in patients with flexible flatfoot with accessory navicular symptoms. From December 2008 to July 2011, 16 patients (21 feet) with a flexible flatfoot, symptomatic accessory navicular, and obvious heel valgus underwent medial displacement calcaneal osteotomy and reconstruction with posterior tibial tendon insertion on the navicular bone. The patients were evaluated preoperatively, 6 weeks and 3, 6, and 12 months postoperatively, and every 6 months thereafter. The clinical examination was undertaken using the American Orthopaedic Foot and Ankle Society ankle and midfoot scores. The radiologic assessments included the arch height, calcaneus inclination angle, talocalcaneal angle, and talar first metatarsal angle on the lateral weightbearing radiograph. The talocalcaneal angle and talar first metatarsal angle was assessed on the anteroposterior view of the weightbearing foot. Heel valgus alignment was assessed on the axial hindfoot radiographs. The mean follow-up duration was 28.5 months (range 18 to 48). All patients were satisfied with the clinical results and were pain free 6 months postoperatively. No cases of wound infection or nerve injury developed. The mean American Orthopaedic Foot and Ankle Society score improved from 53.3 ± 6.5 to 90.8 ± 1.4 at the last follow-up visit (p < .01). The improvements in all radiographic parameters were statistically significant between the preoperative and last follow-up examinations (p < .01). The heel valgus of all patients was corrected. Our results have shown that medial displacement calcaneal osteotomy with reconstruction of the posterior tibial tendon insertion on the navicular bone is an effective treatment of flexible flatfoot with symptomatic accessory navicular, associated with excellent clinical outcomes and correction of the deformity.

Abstract
BACKGROUND Malalignment of the hindfoot can be corrected with a calcaneal osteotomy (CO). A well-selected osteotomy angle in the sagittal plane will reduce the shear force in the osteotomy plane while walking. The purpose was to determine the presence of a relationship between the foot geometry and loading of the calcaneus, which influences the choice of the preferred CO angle. METHODS A static free body force analysis was made of the posterior calcaneal fragment in the second half of the stance phase to determine the main loads: the plantar apeunorosis (PA) and Achilles tendon (AT). The third load is on the osteotomy surface which should be oriented such that the shear component of the force is zero. The force direction of the PA and AT was measured on 58 MRIs of the foot, and the force ratio between both structures was taken from the literature. In addition the PA-to-AT force ratio was estimated for different foot geometries to identify the relationship. RESULTS Based on the wish to minimize the shear force during walking, a mean CO angle was determined to be 33° (SD8) relative to the foot sole. In pes planus foot geometry, the angle should be higher than the mean. In pes cavus foot geometry, the angle should be smaller. CONCLUSION Foot geometry, in particular the relative foot heights is a determinant for the individual angle in performing the sliding calcaneal osteotomy. It is recommended to take into account the foot geometry (arch) when deciding on the CO angle for hindfoot correction.

Abstract
Treatment of adult acquired flexible flat foot deformity can be problematic. Triple arthrodesis for structural correction has been the standard of care, thus sacrificing hind foot motion. The objective of this study was to assess the value of double calcaneal osteotomies in improving structural alignment while maintaining hind foot motion, which may further protect the function of adjacent motion segments. Double calcaneal osteotomies (Evans osteotomy and posterior calcaneal displacement osteotomy) were performed on 17 feet of 14 patients. Postoperative follow-up showed significant improvement in clinical foot and ankle scores.

Abstract
UNLABELLED This study presents a new computer-assisted surgical planning and simulating system that employs a multimedia environment for calcaneal osteotomy surgery. The system uses a full-scale computer-assisted engineering technique for designing and developing preoperative planning modules. The planning system not only presents a real-sized 3-dimensional (3D) image of the calcaneus, but also provides detailed interior measurements of the calcaneus from various cutting planes. The multimedia user interface integrates the function of different software programs in order to plan and simulate the operation. These functions include 3D image model capturing, sectioning, translocation, rotating, and measuring relevant foot anatomy, all of which can be integrated and used for surgical planning, as well as for future study and discussion. Furthermore, because the system is computer based with a multimedia user interface, surgeons can use it to explore the optimal operative procedure. The system also has a databank that can be updated and expanded, and can be used to provide clinical cases to different users for education and training. LEVEL OF CLINICAL EVIDENCE 5.

Abstract
INTRODUCTION Due to advances in technology, segmental gait analysis of the foot is now possible and can elucidate hindfoot deformity in persons with posterior tibial tendon dysfunction (PTTD). This study evaluated the motion of the hindfoot and ankle power following surgical reconstruction for PTTD utilizing a segmental foot model during gait. MATERIALS AND METHODS Twenty patients who underwent posterior tibial tendon reconstruction for Stage 2 PTTD using transfer of the flexor digitorum longus tendon to the navicular tuberosity, reconstruction of the calcaneo-navicular ligament complex, and a medial displacement calcaneal osteotomy were evaluated at a minimum followup of 1 year. Three-dimensional gait analysis was performed utilizing a 4-segment foot model. Temporal-spatial parameters included walking velocity, cadence, step length, and single support time. Sagittal, coronal, and transverse hindfoot motion with respect to the tibia/fibula and ankle power was calculated throughout the gait cycle. RESULTS Walking velocity, cadence, and step length were not significantly different between the study subjects and the normal control group. Study patients did show a significantly smaller single support time on both the affected and unaffected limbs compared to controls. There was no statistical difference in plantarflexion-dorsiflexion, varus-valgus, or ankle push-off power between the affected and unaffected sides of the study subjects, or between the affected side and the controls. CONCLUSION In this preliminary postoperative study, surgical reconstruction for PTTD effects quantifiable objective improvement in walking velocity, hindfoot motion and power.

Abstract
Revision of failed flatfoot surgery presents a unique and challenging dilemma for the foot and ankle surgeon. Revision surgery is focused on establishing a plantigrade foot with correction of the hindfoot valgus, midfoot abduction, and forefoot varus. Successful reconstruction of failed flatfoot surgery begins with a proper evaluation. No treatment algorithm exists for the management of the malaligned flatfoot. Patient complaints, an understanding of the initial deformity and biomechanical problems, and surgeon experience play a role in correction of failed flatfoot surgery.

Abstract
One of the most common presenting problems to most foot and ankle surgical practices is the painful flatfoot. Often, the problem is treated with excellent outcomes through a combination of conservative options. In certain cases, conservative care may not alleviate the associated symptoms of foot, ankle, knee, and possibly even back fatigue, pain of the foot and leg, and arthritis of the midfoot, rearfoot, or ankle. In such cases, multiple surgical options are available to treat the underlying deformity and associated symptoms. it is essential to treat the foot and leg as a unit and not to perform surgical based on rapid recovery abut rather on a long-term stable and lasting outcome.

Abstract
The author presents an alternative approach to the pediatric flexible pes planovalgus patient. Hopefully, this algorithm can serve as a guide and not as a rule. It is meant to serve the foot and ankle surgeon as a means of eliminating the arbitrary assignment of a flatfoot to procedures. Instead, the algorithm assigns procedures to a type of flatfoot. The specific procedures listed are a guide to reduce our failures while continually improving our successes.

Abstract
BACKGROUND The accurate measurement of flatfoot on standing radiographs allows correct diagnosis of the condition and evaluation of reconstructive procedures. METHOD The standing radiographic measurements of patients with symptomatic, adult flatfoot were compared to controls using blinded observers. RESULTS On the lateral radiograph, the talar-to-first metatarsal angle, the calcaneal pitch angle, and the medial cuneiform-fifth metatarsal height differed significantly between the patient group and the controls. The difference in the talar-to-first metatarsal angles on lateral radiographs was the most statistically significant (patient group 21.1 +/- 10.8 degrees and control 7.1 +/- 10.7 degrees, p < 0.0001) with good correlation between readings (intraobserver 0.75, interobserver 0.83). On the anteroposterior (AP) radiograph, the talar head uncoverage distance was the most significantly different measurement between these groups. CONCLUSIONS These findings support the hypothesis that the talar-first metatarsal angle is an accurate radiographic identifier of patients with symptomatic, adult flatfoot.

Abstract
The current trend is to preserve the hindfoot joints to allow for more normal biomechanics and avoid arthritic changes in adjacent joints. Calcaneal osteotomies are effective in the treatment of hindfoot and foot malalignment with an acceptable rate of complications at medium-term follow-up. An important prerequisite should be flexibility and the absence of joint arthritis.

Abstract
The posterior calcaneal displacement osteotomy with flexor digitorum longus tendon transfer is an accepted approach to the stage II posterior tibial tendon dysfunction flatfoot. This reconstructive osteotomy provides a viable alternative to isolated hindfoot arthrodesis procedures. Proper patient selection and sound surgical technique ensure favorable postoperative results. Complications, though limited, may include sural neuritis, peroneal tendonitis, undercorrection, and peritalar arthrosis.

Abstract
The purpose of this study was to investigate the effect on gait in patients who underwent reconstruction for stage II posterior tibial tendon (PTT) dysfunction. Twelve patients with stage II PTT dysfunction underwent surgical reconstruction consisting of debridement of the posterior tibial tendon, flexor digitorum longus tendon transfer to the navicular tuberosity, medial displacement calcaneal osteotomy, and spring ligament reconstruction. Midfoot arthrodesis was performed in six patients and gastrocnemius recession in three. Gait analysis was performed 2 weeks prior to surgery and 1 year postoperatively. Preoperative and postoperative data were compared to determine differences in temporal-spatial parameters, lower limb kinematics, and ankle push-off power. Step length for the operated side increased from 52.6 +/- 9.6 cm before the surgery to 57.5 +/- 7.1 cm after the surgery (p =.048). Cadence improved from 100.2 +/- 10.7 steps/min to 109.1 +/- 8.5 steps/min (p =.05), thus increasing velocity from 87.6 +/- 22.6 cm/s to 103.4 +/- 15.9 cm/s (p =.042). Single support percentage was unchanged. Maximum sagittal ankle joint power at push-off increased from 0.79 +/- 0.35 W before surgery to 1.2 +/- 0.5 W after surgery (p =.042). There were statistically significant improvements in all radiographic parameters studied. This is the first prospective study to evaluate the in vivo effects on gait in patients undergoing this common surgical procedure. Analysis demonstrated statistically significant improvement in kinetic and kinematic parameters of gait function.

Abstract
O objetivo do estudo foi avaliar a osteotomia calcaneana de deslizamento medial de Koutsogiannis modificada, sob parâmetros clínicos e radiográficos. Entre janeiro de 1997 e abril de 2001, vinte e nove pés de dezenove pacientes portadores de pé plano valgo flexível idiopático, com idade média de 11,36 anos, foram submetidos ao procedimento de Koutsogiannis modificado pela varização da extremidade deslizada, com um seguimento médio de dezesseis meses. A cirurgia foi indicada para pacientes com sintomas de dor e fadiga e portadores de deformidade. Clinicamente, dezessete pacientes referiram estar sem dor e dezesseis não apresentaram deformidade residual, sendo notada a correção da deformidade do retropé. Obteve-se 9,36 em média na análise dos resultados subjetivos pós-operatórios, cuja graduação era de 0-10. Dois maus resultados de dor e persistência da deformidade foram atribuídos a portadores de hiperfrouxidão ligamentar, com deformidade grave pré-operatória. O estudo radiográfico revelou, na incidência lateral, decréscimo dos valores médios pré-operatórios dos ângulos talocalcaneano e talo-primeiro metatarso de 29,7 e 11,33 graus para valores pós-operatórios de 23,05 e 7,76 graus respectivamente. Na incidência antero-posterior notou-se decréscimo do valor médio do ângulo talocalcaneano de 36,39 para 35,42 graus. Concluiu-se que o procedimento de Koutsogiannis mostrou-se eficaz para o tratamento de pacientes de dez a treze anos, portadores de pé plano valgo flexível idiopático leve e moderado, apresentando melhoria estética, alívio sintomático e melhora radiográfica.

Abstract
Numerous surgical procedures have been described for the treatment of the adult acquired flatfoot deformity. The surgeon should review in detail all the clinical, radiographic and imaging tests and propose the best surgical procedure for the patient. Although flexor tendon transfer has shown excellent results, the split anterior tibial tendon transfer is a second option. If used properly, the Cobb procedure results in less functional loss, since only half of the anterior tibial tendon is transferred. Furthermore, the flexor tendon is not disrupted and continues its primary function in the foot and ankle. Ultimately, the goals of the surgical procedure are to alleviate the patient's symptoms and pain, restore a normal foot alignment, and limit the loss of foot and ankle function without causing any complications.
