Aims. To assess if older symptomatic children with club foot deformity differ in perceived disability and foot function during gait, depending on initial treatment with Ponseti or surgery, compared to a control group. Second aim was to investigate correlations between foot function during gait and perceived disability in this population. Methods. In all, 73 children with idiopathic club foot were included: 31 children treated with the Ponseti method (mean age 8.3 years; 24 male; 20 bilaterally affected, 13 left and 18 right sides analyzed), and 42 treated with primary surgical correction (mean age 11.6 years; 28 male; 23 bilaterally affected, 18 left and 24 right sides analyzed). Foot function data was collected during walking gait and included Oxford Foot Model kinematics (Foot Profile Score and the range of movement and average position of each part of the foot) and plantar pressure (peak pressure in five areas of the foot). Oxford Ankle Foot Questionnaire, Disease Specific Index for club foot, Paediatric Quality of Life Inventory 4.0 were also collected. The gait data were compared between the two club foot groups and compared to control data. The gait data were also correlated with the data extracted from the questionnaires. Results. Our findings suggest that symptomatic children with club foot deformity present with similar degrees of gait deviations and perceived disability regardless of whether they had previously been treated with the Ponseti Method or surgery. The presence of sagittal and coronal plane hindfoot deformity and coronal plane forefoot deformity were associated with higher levels of perceived disability, regardless of their initial treatment. Conclusion. This is the first paper to compare outcomes between Ponseti and surgery in a symptomatic older club foot population seeking further treatment. It is also the first paper to correlate foot function during gait and perceived disability to establish a link between deformity and subjective outcomes.

Progressive collapsing foot deformity (PCFD) is a complex foot deformity with varying degrees of hindfoot valgus, forefoot abduction, forefoot varus, and collapse or hypermobility of the medial column. In its management, muscle and tendon balancing are important to address the deformity. Peroneus brevis is the primary evertor of the foot, and the strongest antagonist to the tibialis posterior. Moreover, peroneus longus is an important stabilizer of the medial column. To our knowledge, the role of peroneus brevis to peroneus longus tendon transfer in cases of PCFD has not been reported. This study evaluates patient reported outcomes including pain scores and any associated surgical complications for patients with PCFD undergoing isolated peroneus brevis to longus tendon transfer and gastrocnemius recession. Patients with symptomatic PCFD who had failed non-operative treatment, and underwent isolated soft tissue correction with peroneus brevis to longus tendon transfer and gastrocnemius recession were included. Procedures were performed by a single surgeon at a large University affiliated teaching hospital between January 1 2016 to March 31 2021. Patients younger than 18 years old, or undergoing surgical correction for PCFD which included osseous correction were excluded. Patient demographics, medical comorbidities, procedures performed, and pre and post-operative patient related outcomes were collected via medical chart review and using the appropriate questionnaires. Outcomes assessed included Visual Analogue Scale (VAS) for foot and ankle pain as well as sinus tarsi pain (0-10), patient reported outcomes on EQ-5D, and documented complications. Statistical analysis was utilized to report change in VAS and EQ-5D outcomes using a paired t-test. Statistical significance was noted with p<0.05. We analysed 43 feet in 39 adults who fulfilled the inclusion criteria. Mean age was 55.4 ± 14.5 years old. The patient reported outcome mean results and statistical analysis are shown in Table one below. Mean pre and post-operative foot and ankle VAS pain was 6.73, and 3.13 respectively with a mean difference of 3.6 (p<0.001, 95% CI 2.6, 4.6). Mean pre and post-operative sinus tarsi VAS pain was 6.03 and 3.88, respectively with a mean difference of 2.1 (p<0.001, 95% CI 0.9, 3.4). Mean pre and post-operative EQ-5D Pain scores were 2.19 and 1.83 respectively with a mean difference of 0.4 (p=0.008, 95% CI 0.1, 0.6). Mean follow up time was 18.8 ± 18.4 months. Peroneus brevis to longus tendon transfer and gastrocnemius recession in the management of symptomatic progressive collapsing foot deformity significantly improved sinus tarsi and overall foot and ankle pain. Most EQ-5D scores improved, but did not reach statistically significant values with the exception of the pain score. This may have been limited by our cohort size. To our knowledge, this is the first report in the literature describing clinical results in the form of patient reported outcomes following treatment with this combination of isolated soft tissue procedures for the treatment of PCFD.

Hind foot Charcot deformity is a disastrous complication of diabetic neuropathy and can lead to instability, ulceration and amputation. The treatment of these patients is controversial. Internal stabilisation and external fixation have demonstrated variable results of limb salvage and some authorities thus advise patients to undergo elective amputation. We report a series of 9 diabetic patients with severe hind foot deformity complicated by ulceration in 5/9, who underwent acute corrective internal fixation with successful correction of deformity, healing of ulceration in 4/5 patients and limb salvage in all cases. Conservative measures such as total contact casting were tried in 5 patients had predominant varus deformity, 2 with valgus deformity and 2 with unstable ankle joints. 5 patients had developed secondary ulceration. All patients underwent corrective hind foot fusion with tibio-talo-calcaneal arthrodesis using a retrograde intramedullary nail fixation and screws and bone grafting. One patient also with fixed planovalgus deformity of the foot underwent a corrective midfoot reconstruction. Patients were followed up in a diabetic/orthopaedic multidisciplinary foot clinic and were treated with total contact casting. (Mean follow up time was 15.6 ±6.9months) In all patients the deformity was corrected with successful realignment to achieve a plantigrade foot. Healing of the secondary ulcers was achieved in 4/5 cases and limb salvage was achieved in all cases. Three patients underwent further surgical procedure to promote bone fusion. One patient required removal of a significantly displaced fixation screw. Two patients had postoperative wound infections which that were treated with initially intravenous antibiotic therapy and then negative pressure wound therapy. In conclusion, internal fixation for severe hind foot deformity together with close follow up in a multidisciplinary diabetic/orthopaedic foot clinic can be successful in diabetic patients with advanced Charcot osteoarthropathy and secondary ulceration

Introduction. Charcot neuroarthropathy is a limb threatening condition and the optimal surgical strategy for limb salvage in gross foot deformity remains unclear. We present our experience of using fine wire frames to correct severe midfoot deformity, followed by internal beaming to maintain the correction. Materials and Methods. Nine patients underwent this treatment between 2020–2023. Initial deformity correction by Ilizarov or hexapod butt frame was followed by internal beaming with a mean follow up of 11 months. A retrospective analysis of radiographs and electronic records was performed. Meary's angle, calcaneal pitch, cuboid height, hindfoot midfoot angle and AP Meary's angle were compared throughout treatment. Complications, length of stay and the number of operations are also described. Results. Mean age was 53 years (range:40–59). Mean frame duration was 3.3 months before conversion to beaming. Prior frame-assisted deformity correction resulted in consistently improved radiological parameters. Varying degrees of subsequent collapse were universal, but 5 patients still regained mobility and a stable, plantargrade, ulcer-free foot. Complications were common, including hardware migration (N=6,66%), breakage (N=2,22%), loosening (N=3,33%), infection (N=4,44%), 1 amputation and an unscheduled reoperation rate of 55%. Mean cumulative length of stay was 42 days. Conclusions. Aggressive deformity correction and internal fixation for Charcot arthropathy requires strategic and individualised care plans. Complications are expected for each patient. Patients must understand this is a limb salvage scenario. This management strategy is resource heavy and requires timely interventions at each stage with a well-structured MDT delivering care. The departmental learning points are to be discussed

Introduction. Limb-length discrepancy (LLD) is a common postoperative complication after total hip arthroplasty (THA). This study focuses on the correlation between patients’ perception of LLD after THA and the anatomical and functional leg length, pelvic and knee alignments and foot height. Previous publications have explored this topic in patients without significant spinal pathology or previous spine or lower extremity surgery. The objective of this work is to verify if the results are the same in case of stiff or fused spine. Methods. 170 patients with stiff spine (less than 10° L1-S1 lordosis variation between standing and sitting) were evaluated minimum 1 year after unilateral primary THA implantation using EOS® images in standing position (46/170 had previous lumbar fusion). We excluded cases with previous lower limbs surgery or frontal and sagittal spinal imbalance. 3D measures were performed to evaluate femoral and tibial length, femoral offset, pelvic obliquity, hip-knee-ankle angle (HKA), knee flexion/hyperextension angle, tibial and femoral rotation. Axial pelvic rotation was measured as the angle between the line through the centers of the hips and the EOS x-ray beam source. The distance between middle of the tibial plafond and the ground was used to investigate the height of the foot. For data with normal distribution, paired Student's t-test and independent sample t-test were used for analysis. Univariate logistic regression was used to determine the correlation between the perception of limb length discrepancy and different variables. Multiple logistic regression was used to investigate the correlation between the patient perception of LLD and variables found significant in the univariate analysis. Significance level was set at 0.05. Results. Anatomical femoral length correlated with patients’ perception of LLD but other variables were significant (the height of the foot, sagittal and frontal knee alignment, pelvic obliquity and pelvic rotation more than 10°). Interestingly some factors induced an unexpected perception of LLD despite a non-significant femoral length discrepancy less than 1cm (pelvic rotation and obliquity, height of the foot). Conclusions. LLD is a multifactorial problem. This study showed that the anatomical femoral length as the factor that can be modified with THA technique or choice of prosthesis is not the only important factor. A comprehensive clinical and radiological evaluation is necessary preoperatively to investigate spinal stiffness, pelvic obliquity and rotation, sagittal and coronal knee alignment and foot deformity in these patients. Our study has limitations as we do not have preoperative EOS measurements for all patients. We cannot assess changes in leg length as a result of THA. We also did not investigate the degree of any foot deformities as flat foot deformity may potentially affect the patients perception of the leg length. Instead, we measured the distance between the medial malleolus and ground that can reflect the foot arch height. More cases must be included to evaluate the potential influence of pelvis anatomy and functional orientation (pelvic incidence, sacral slope and pelvic tilt) but this study points out that spinal stiffness significantly decreases the LLD tolerance previously reported in patients without degenerative stiffness or fusion

Untreated clubfoot results in serious disability, but mild to moderate residual deformities can still cause functional limitations and pain. Measuring the impact of clubfoot deformities on children's wellbeing is challenging. There is little literature discussing the variability in outcomes and implications of clubfoot based on where geographically the child resides. Although the use of patient reported outcome measures (PROMs) is steadily growing in pediatric orthopaedics, few studies on clubfoot have incorporated them. The most widely used PROM for pediatric foot and ankle pathology is the Oxford Foot and Ankle Questionnaire for Children (OXFAQ-C) that include a physical, school and play, emotional and shoe wear domains. The aim of this study is to evaluate the validity and regional differences in scores of the OXFAQ-C questionnaire to identify functional disability in children with clubfoot in India and Canada. This is a retrospective cohort study of children in Indian and Canadian clubfoot registries aged 5-16 years who completed >1 parent or child OXFAQ-C. The OXFAQ-C was administered once in 01/2020 to all patients in the Indian registry, and prospectively between 06/2019 and 03/2021 at initial visit, 3, 6, 12 months post-intervention, then annually for the Canadian patients. Demographic, clubfoot, and treatment data were compared to OXFAQ-C domain scores. Descriptive statistics and regression analysis were performed. Parent-child concordance was evaluated with Pearson's Coefficient of Correlation (PCC). The cohort had 361 patients (253 from India, 108 from Canada). Non-idiopathic clubfoot occurred in 15% of children in India and 5% in Canada, and bilateral in 53% in India and 50% in Canada. Tenotomy rate was 75% in India and 62% in Canada. Median age at presentation was 3 months in India and 1 month in Canada. Mean Pirani score at presentation and number of Ponseti casts were 4.9 and 6.1 in India and 5.3 and 5.7 in Canada, respectively. Parents reported lower scores in all domains the older the child was at presentation (p Canadians scored significantly lower for all domains (p < 0 .001), with the difference being larger for child-reported scores. The greatest difference was for physical domain. Canadian parents on average scored their child 6.21 points lower than Indian parents, and Canadian children scored a mean of 7.57 lower than Indian children. OXFAQ-C scores differed significantly between Indian and Canadian children despite similar demographic and clubfoot characteristics. Younger age at presentation and tenotomy may improve OXFAQ-C scores in childhood. Parent-child concordance was strong in this population. The OXFAQ-C is an adequate tool to assess functional outcomes of children with clubfeet. Cultural validation of patient reported outcome tools is critical

Introduction. Amputation or disarticulation is a reliable option for management of severe foot deformities and limb-length discrepancies, the surgical restoration of which are unpredictable or unfavourable. Of the various surgeries involving foot ablation, Syme's amputation is preferred for congenital deformities as it provides a growing, weight bearing stump with proprioception and cushioning. Materials and Methods. We reviewed data of all children who underwent Syme's amputation over the past 13 years at our institution. Surgical technique followed the same principles for Syme's but varied with surgeons. Results. Ten boys and ten girls, with an average age of 18 months and average follow up of 70 months were included in the study. The most common indication was fibular hemimelia. Wound complications were reported in three children, phantom pain in one, heel pad migration in two. None had wound dehiscence, flap necrosis, stump overgrowth, or calcaneal regrowth. None of this required surgical intervention. One child required an amputation at a higher-level secondary to a congenital malformation of nervous tissue in the affected leg. Prosthetic compatibility was 94.7 % and none used mobility aids. Six children participated in sports. Conclusions. Syme amputation is a safe and potentially advantageous procedure in children, with a low incidence of complications to offer patients with non-salvageable foot conditions. It offers good prosthetic use with minimal risk of complications and can offer patients a functional solution with only one surgical intervention throughout their childhood

The Ponseti method is the gold standard treatment for clubfoot. It begins in early infancy with weekly serial casting for up to 3 months. Globally, a commonly reported barrier to accessing clubfoot treatment is increased distance patients must travel for intervention. This study aims to evaluate the impact of the distance traveled by families to the hospital on the treatment course and outcomes for idiopathic clubfoot. No prior studies in Canada have examined this potential barrier. This is a retrospective cohort study of patients managed at a single urban tertiary care center for idiopathic clubfoot deformity. All patients were enrolled in the Pediatric Clubfoot Research Registry between 2003 and April 2021. Inclusion criteria consisted of patients presenting at after percutaneous Achilles tenotomy. Postal codes were used to determine distance from patients’ home address to the hospital. Patients were divided into three groups based on distance traveled to hospital: those living within the city, within the Greater Metro Area (GMA) and outside of the GMA (non-GMA). The primary outcome evaluated was occurrence of deformity relapse and secondary outcomes included need for surgery, treatment interruptions/missed appointments, and complications with bracing or casting. A total of 320 patients met inclusion criteria. Of these, 32.8% lived in the city, 41% in the GMA and 26% outside of the GMA. The average travel distance to the treatment centre in each group was 13.3km, 49.5km and 264km, respectively. Over 22% of patients travelled over 100km, with the furthest patient travelling 831km. The average age of presentation was 0.91 months for patients living in the city, 1.15 months for those within the GMA and 1.33 months for patients outside of the GMA. The mean number of total casts applied was similar with 7.1, 7.8 and 7.3 casts in the city, GMA and non-GMA groups, respectively. At least one two or more-week gap was identified between serial casting appointments in 49% of patients outside the GMA, compared to 27% (GMA) and 24% (city). Relapse occurred in at least one foot in 40% of non-GMA patients, versus 27% (GMA) and 24% (city), with a mean age at first relapse of 50.3 months in non-GMA patients, 42.4 months in GMA and 35.7 months in city-dwelling patients. 12% of the non-GMA group, 6.8% of the GMA group and 5.7% of the city group underwent surgery, with a mean age at time of initial surgery of 79 months, 67 months and 76 months, respectively. Complications, such as pressure sores, casts slips and soiled casts, occurred in 35% (non-GMA), 32% (GMA) and 24% (city) of patients. These findings suggest that greater travel distance for clubfoot management is associated with more missed appointments, increased risk of relapse and treatment complications. Distance to a treatment center is a modifiable barrier. Improving access to clubfoot care by establishing clinics in more remote communities may improve clinical outcomes and significantly decrease the burdens of travel on patients and families

Progressive collapsing foot deformity (PCFD) is a common condition with an estimated prevalence of 3.3% in women greater than 40 years. Progressive in nature, symptomatic flatfoot deformity can be a debilitating condition due to pain and limited physical function; it has been shown to have one of the poorest preoperative patient reported outcome scores in foot and ankle pathologies, second to ankle arthritis. Operative reconstruction of PCFD can be performed in a single-stage manner or through multiple stages. The purpose of this study is to compare costs for non-staged (NS) flatfoot reconstructions, which typically require longer hospital stays, with costs for staged (S) reconstructions, where patients usually do not require hospital admission. To our knowledge, the comparison between single-staged and multi-staged flatfoot reconstructions has not been previously done. This study will run in conjunction with one that compares rates of complications and reoperation, as well as patient reported outcomes on function and pain associated with S and NS flatfoot reconstruction. Overall, the goal is to optimize surgical management of PCFD, by addressing healthcare costs and patient outcomes. At our academic centre with foot and ankle specialists, we selected one surgeon who primarily performs NS flatfoot reconstruction and another who primarily performs S procedures. Retrospective chart reviews of patients who have undergone either S or NS flatfoot reconstruction were performed from November 2011 to August 2021. Length of operating time, number of primary surgeries, length of hospital admission, and number of reoperations were recorded. Cost analysis was performed using local health authority patient rates for non residents as a proxy for health system costs. Rates of operating room per hour and hospital ward stay per diem in Canadian dollars were used. The analysis is currently ongoing. 72 feet from 66 patients were analyzed in the S group while 78 feet from 70 patients were analyzed in the NS group. The average age in the S and NS group are 49.64 +/− 1.76 and 57.23 +/− 1.68 years, respectively. The percentage of female patients in the S and NS group are 63.89% and 57.69%, respectively. All NS patients stayed in hospital post-operatively and the average length of stay for NS patients is 3.65 +/− 0.37 days. Only 10 patients from S group required hospital admission. The average total operating room cost including all stages for S patients was $12,303.12 +/− $582.20. When including in-patient ward costs for patients who required admission from S group, the average cost for operating room and in-patient ward admission was $14,196.00 +/− $1,070.01 after flatfoot reconstruction. The average in-patient ward admission cost for NS patients was $14,518.83 +/− $1,476.94 after flatfoot reconstruction. The cost analysis for total operating room costs for NS patients are currently ongoing. Statistical analysis comparing S to NS flatfoot reconstruction costs are pending. Preliminary cost analysis suggests that multi-staged flatfoot reconstruction costs less than single-staged flatfoot reconstruction. Once full assessment is complete with statistical analysis, correlation with patient reported outcomes and complication rate can guide future PCFD surgical management

Introduction. Patients undergoing total knee arthroplasty (TKA) with end-stage osteoarthritis of knee have secondary foot and ankle pathology. Some compensatory changes occur at ankle and subtalar joint secondary to malalignment and deformity at the knee joint. Purpose was to evaluate the changes in hindfoot malalignment and foot deformities in patients with advanced osteoarthritis of knee requiring TKA and effect of correction of knee deformities post TKA on foot/Ankle alignment. Methods. 61 consecutive patients with Kellgren-Lawrence grade IV osteoarthritis knee undergoing TKA were enrolled in a prospective blinded study. Demographic data, deformities at knee and ankle, hindfoot malalignment and functional outcome scores such as VAS, KSS, WOMAC scores, Foot and Ankle Disability Index (FADI) and Foot posture index (FPI) were recorded preoperatively and postoperatively at 6, 12 weeks and final follow up (range: 6–21 months; mean: 14.2months). Results. Statistically significant improvement was observed in KSS score, WOMAC score, FADI and FPI after TKA. There was improvement in ankle valgus after correction of knee varus deformity. Hind foot changes mainly occured at subtalar joint. Hallux valgus (10 patients), and Pesplanus (5 patients) were associated with advanced osteoarthritis of knee. Gait profile score and Gait deviation index improved significantly after TKA. There was increased stance phase and decreased stride length in knee osteoarthritis patients which improved after TKA. Conclusion. Hind foot malalignment with foot deformities (hind foot valgus) occur secondary to knee malalignment and deformities (varus deformity) in advanced osteoarthritis of knee which subsequently improve following TKA

Fibular Hemimelia is not just a fibular anomaly but there is entire limb involvement with varied expression in each segment. Factors which we have considered in treatment are the amount of fibula present, percentage of shortening, tibial and leg deformity and foot deformity. Residual or recurrent foot deformity is the prime reason for unsatisfactory results, so we have used Paley's classification which takes into consideration foot deformity. Our series is of 29 cases, Paley type I-7, Type II-6, Type III-16 and none of type IV. Tibial lengthening (+/−) bow correction was performed in 28 cases. Supramalleolar osteotomy was done in 4 cases. In foot, soft tissue release only was done in 6 cases and soft tissue release with osteotomy (subtalar or calcaneal) was done in 14 cases. Amputation was done in 2 cases. Age ranged from 11 months to 16 years. Mean follow up was 4.2 years. Mean lengthening was 3.5 cm. Desires lengthening was achieved in 21/29 cases and plantigrade foot was achieved in 16/29 cases. Complications faced were recurrence of foot deformity, knee valgus, knee fixed flexion deformity, knee subluxation and pin tract problems. Less than 3 rays and more than 25 cm of limb length discrepancy were poor prognostic factors. We had 7 excellent, 16 good and 6 poor results. To conclude, it is difficult to achieve the aim of plantigrade foot and limb length equality in all cases but radical surgery with foot correction and tibial lengthening can give good results

Introduction. Hind foot Charcot deformity is a disastrous complication of diabetic neuropathy and can lead to instability, ulceration and major amputation. The treatment of these patients is controversial. Internal stabilization and/or external fixation have demonstrated variable results of limb salvage and some authorities thus advise patients to undergo elective major amputation. However, we report a series of 9 diabetic patients with severe hind foot deformity complicated by ulceration in 5/9, who underwent acute corrective internal fixation with successful correction of deformity, healing of ulceration in 4/5 patients and limb salvage in all cases. Methods. We treated 9 diabetic patients attending a multidisciplinary diabetic/orthopaedic foot clinic with progressive severe Charcot hind foot deformity despite treatment with total contact casting, 5 with predominant varus deformity and 2 with valgus deformity and 2 with unstable ankle joints. Five patients had developed secondary ulceration. All patients underwent corrective hind foot fusion with tibiotalo-calcaneal arthrodesis using a retrograde intra-medullary nail fixation and screws and bone grafting. One patient also with fixed plano-valgus deformity of the foot underwent a corrective mid-foot reconstruction. Results. Patients were followed up closely in the diabetic /orthopaedic multidisciplinary foot clinic and were treated with total contact casting. (Mean follow up time was 15.6 ±6.9months) In all patients the deformity was corrected with successful realignment to achieve a plantigrade foot. Healing of the secondary ulcers was achieved in 4/5casesand limb salvage was achieved in all cases. Three patients underwent further surgical procedure to promote bone fusion. One patient required removal of a significantly displaced fixation screw. In another patient with previously existing heel ulceration, the fixation device was removed due to progressive ulceration. However, by then, the patient had achieved fibrous union and stability of the hind foot. Two patients had postoperative wound infections which that were treated with initially intravenous antibiotic therapy and then negative pressure wound therapy. Conclusion. In conclusion, internal fixation for severe hind foot deformity together with close follow up in a multidisciplinary diabetic/orthopaedic foot clinic can be successful in diabetic patients with advanced Charcot osteoarthropathy and secondary ulceration

Background. The adult acquired flat foot is caused by a complete or partial tear of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medializing calcaneal osteotomy for recontruction of the deformity. Material & Methods. Twenty-six patients (31 feet) with an average age of 58 years (36–75) were operated for an acquired flat foot deformity. The patients were seen before surgery, one year after surgery and an average of 85 months after surgery to assess the following parameters: AOFAS Score, VAS Score for pain (0–10). Foot x-rays in full weightbearing position (dorsoplantar and lateral) were done at every visit in order to assess the following parameters: tarsometatarsale angle on the dorsoplantar and lateral x-ray, talocalcaneal angle on the lateral x-ray, calcaneal pitch angle and medial cuneiforme height on the lateral x-ray. Results. The AOFAS hindfoot score improved from 46.4 to 89.5 (max.: 100) points 1 year postoperatively und decreased to 87.8 points at the last follow-up. VAS for pain decreased from 6.6 to 1.1 at the one year follow-up and increased to 1.5 at the last follow-up. All radiologic parameters improved and stayed without significant changes over time. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. In six patients the screws had to be removed. Apart from that no other revision surgery had to be done. Conclusion. Flexor digitorum longus transfer together with medializing calcaneal osteotomy provides excellent results for the therapy of acquired flat foot deformity. The results did not change significantly over time

Complex congenital foot deformities pose a challenge to the surgeon due to poor results after extensive surgery. We report the clinical outcomes of children with complex congenital foot deformities treated with UMEX® (Universal mini-external fixator System) frames. This is a prospective review of our experience in patients treated in this way, from 2004 to 2011. The indications for treatment included resistant/recurrent Congenital Talipes Equino Varus (CTEV), cavo-varus deformity secondary to Charcot-Marie-Tooth disease, arthrogryposis, fibular hemimelia and other congenital abnormalities. A total of 32 children (35 feet) have been treated, out of which 22 were male and 10 were female patients. Age at surgery ranged from 3 to 15 years (median age – 7 years). Three patients underwent bilateral procedures; the reminder (29 patients) underwent unilateral foot operations. Twenty-eight patients had undergone previous surgery including soft-tissue and/or bony corrective procedures. The frames were removed at an average of 69 days after application, and the patients spent a further 6 weeks in a walking cast. Good functional outcomes were noted in 26 patients in the first postoperative year and in 19 patients in the fifth postoperative year. Further operations were needed in 10 patients. Complications occurred in 10 patients, predominantly pin-site infections and 1 case of bony overgrowth at pin-site and 1 of proximal tibio-fibular diastasis. This is a simple fixator to use with a short learning curve. In groups of patients with complex congenital abnormalities, we achieved good functional outcome with low-complication rates

Tibiotalocalcaneal arthrodeisis is performed for a variety of conditions, including advanced osteoarthritis, Charcot arthropathy, rheumatoid arthritis, post-traumatic arthrosis and foot deformities such as fixed equinovarus. There have been few published studies showing the results of such a procedure for limb salvage. Over a period of 11 years between 1996 and 2007, 18 patients underwent calcaneotalotibial arthrodeisis using either cannulated screws or a retrograde intramedullary locking nail. Post-operative rehabilitation regimes were standardised. VAS, AOFAS ankle-hindfoot, SF-36 and patient satisfaction scores were obtained and analysed. Eighteen patients (10 male and 8 female) with 19 ankles underwent tibiotalocalcaneal arthrodeisis at an average age of 52.3 (31.4 to 70.2 years). Seven patients had cavovarus deformity, six had osteoarthritis, three had Charcot's joint, two had failed previous fusions and one patient had a footdrop post-T12 tumour resection. Twelve right and seven left fusions were performed, with six cannulated screws and 13 retrograde nails. The mean time to complete fusion was 5.89 (3 to 11) months in 18 ankles (94.7%). There was one pseudoarthrosis (5.3%). Patients were followed up for an average of 35.6 (11 to 144) months. Four wound infections (21%) occurred post-operatively. Two patients died from unrelated caused whilst on follow-up. Thriteen patients returned for follow-up scoring. VAS scores improved from 7.85 to 2.54 (p=0.00). AOFAS ankle-hindfoot scores improved from 30.50 to 63.62 (p=0.00). SF-36 scores also improved in several parameters. Physical function improved from 40.38 to 66.15 (p=0.02); physical role improved from 15.38 to 53.85 (p=0.03); Bodily pain improved from 36.69 to 62.23 (p=0.00); emotional role improved from 69.23 to 100 (p=0.04); and mental health improved from 62.77 to 0.15 (p=0.04). Eleven patients (84.6%) reported good to excellent satisfaction and expectation scores. Hindfoot arthrodesis, via retrograde imtramedullary nailing or cannulated screw insertion, are effective techniques for treating complex foot deformities and often is the only alternative to amputation. Although a demanding procedure with high potential complications, they provide effective relief from pain, improves the quality of life, and has high patient satisfaction

Down syndrome (DS), is a genetic disorder caused by a third copy of the 21st chromosome (Trisomy 21), featuring typical facial characteristics, growth delays and varying degrees of intellectual disability. Some degree of immune deficiency is variably present. Multiple orthopaedic conditions are associated, including stunted growth (90%), ligamentous laxity (90%), low muscle tone (80%), hand and foot deformities (60%), hip instability (30%), and spinal abnormalities including atlanto-axial instability (20%) and scoliosis. Hip disease severity varies and follows a variable time course. Rarely a child presents with DDH, but during the first 2 years the hips are characteristically stable but hypermobile with well-formed acetabulae. Spontaneous subluxation or dislocation after 2 presents with painless clicking, limping or giving way. Acute dislocation is associated with moderate pain, increased limp and reduced activity following minor trauma. Hips are reducible under anesthesia, but recurrence is common. Eventually concentric reduction becomes rarer and radiographic dysplasia develops. Pathology includes: a thin, weak fibrous capsule, moderate to severe femoral neck anteversion and a posterior superior acetabular rim deficiency. A number of femoral and acetabular osteotomies have been reported to treat the dysplasia, with acetabular redirection appearing to be most successful. However, surgery can be associated with a relatively high infection rate (20%). Additionally, symptomatic femoral head avascular necrosis can occur as a result of slipped capital femoral epiphysis. Untreated dysplasia patients can walk with a limp and little pain into the early twenties even with fixed dislocation. Pain and decreasing hip function is commonly seen as the patient enters adult life. Occasionally the hip instability begins after skeletal maturity. Total hip arthroplasty (THA) is the standard treatment when sufficient symptoms have developed. The clinical outcomes of 42 THAs in patients with Down syndrome were all successfully treated with standard components. The use of constrained liners to treat intra-operative instability occurred in eight hips and survival rates were noted between 81% and 100% at a mean follow-up of 105 months (6 – 292 months). A more recent study of 241 patients with Down syndrome and a matched 723-patient cohort from the Nationwide Inpatient Sample compared the incidence of peri-operative medical and surgical complications in those who underwent THA. Compared to matched controls, Down syndrome patients had an increased risk of complications: peri-operative (OR, 4.33; P<.001), medical (UTI & Pneumonia OR, 4.59; P<.001) and surgical (bleeding OR, 3.51; P<.001), Mean LOS was 26% longer (P<.001). While these patients can be challenging to treat, excellent surgical technique and selective use of acetabular constraint can reliably provide patients with excellent pain-relief and improved function. Pre-operative education of all clinical decision makers should also reinforce the increased risk of medical and surgical complications (wound hemorrhage), and lengths of stay compared to the general population

Symptomatic flexion deformity of proximal interpahalangeal joint (PIPJ) is one of the most common foot deformities and usually treated with arthrodesis. In general, percutaneous K-wires are used to stabilize the joint after excision of cartilage. K-wires projecting out of the toe need special care and can occasionally be dislodged accidentally. Furthermore issues such as cellulitis, pin tract infections, rarely osteomyelitis and need for removal make alternative fixation methods desirable. Smart toe is an intra-osseous titanium memory implant, which is stored frozen. It expands on insertion and does not require removal. 18 consecutive K-wire PIPJ arthrodesis were compared with 18 Smart toe PIP fusions with a mean follow up of 6 months. Post operative forefoot scores and complications were documented. Patient satisfaction was higher and complications were lower with Smart toe fusions than with K-wire arthrodesis. Fusion of PIP joints with smart toe is an effective and safer alternative to using K-wires. Although more expensive, higher patient satisfaction and lower complication rate may offset the extra cost of the implant

We present our experience of using tension band plates to achieve guided growth in children for correction of calcaneus deformity of the ankle. 11 consecutive patients (13 ankles) fulfilled the inclusion criteria over a 4-year period. All underwent surgical treatment using a flexible two hole plate and screws on the posterior aspect of distal tibial physis. Measurements were done on preoperative, intraoperative screening and 1-year post operative plain AP and lateral ankle radiographs. The anterior distal tibia angle (ADTA), lateral distal tibial angle (LDTA) and screw divergence angle (angle subtended by lines passing through the long axis of the screws) were used to assess the deformity correction. A 2 tailed student t-test was carried out on the initial and 1-year post-op measurements to determine statistical significance with a p value <0.05 considered as significant. There were 10 residual clubfoot deformities, 2 post-traumatic deformities and 1 spinal tumor causing deformity. The average age of the patients was 10 years 5 months (range 4 to 13 years). There were 9 males and 2 females. The ADTA showed a statistically significant change with a p value of 0.0008 with a mean correction of 8.6 degrees (range of 2.3 to 15.6 degrees). The SDA demonstrated a mean correction of 15.4 degrees (range 0.3 to 41.8 degrees), p=0.002. The LDTA did not change significantly (p= 0.08), thus confirming no coincidental coronal plane deformity had occurred. 5 ankles required revision of fixation due to metalwork reaching its maximum limit of divergence at an average of 1 year. 2 ankles had screw pulled out due to osteolysis around the screw. There were no cases of infection. We report satisfactory short-term results of correction of calcaneus deformity using a flexible tension band plate and screws system

We report the clinical outcomes of children with complex congenital foot deformities treated with UMEX® mini-external fixators. This is a prospective review of our experience in patients treated in this way, from 2004. The indications for treatment were resistant/recurrent Congenital Talus Equina Varus(CTEV), cavo-varus deformity secondary to Charcot-Marie-Tooth disease, arthrogryposis, fibular hemimelia and other congenital abnormalities. In addition, one patient underwent this treatment since he was allergic to casting material. A total of 32 children (35 feet) have been treated, with a male to female ratio of 22:10 respectively. The patient-age at operation ranged between 3 and 15 years (median age −7 years). Three patients underwent bilateral procedures and 29 patients underwent unilateral foot operations. Twenty-eight patients underwent previous soft-tissue and bony corrective operations with serial casting. The frames were removed at an average of 69 days after application with a further 6 weeks in a walking cast. Seventy-nine percent of the patients had good functional outcome. Further operations were needed in 10 patients. Complications occurred in 10 patients, including pin-site infections, bony overgrowth at pin-site and proximal tibio-fibular diastasis. In conclusion, this is a simple fixator to use with a small learning curve. In groups of patients with complex congenital abnormalities, we achieved good functional outcome with low-complication rates

Background. Lack of ankle dorsiflexion secondary to a tight gastrocnemius-soleus complex is believed to be a contributing factor in forefoot pain particularly metatarsalgia. It is believed that by lengthening the gastroc-soleus complex weight is distributed more evenly over the foot reducing symptoms. However lengthening any tendon, especially using a percutaneous method carries risks of over-lengthening. In the summer of 2008 we started to see some patients who complained of significant weakness in their Achilles tendons following the 3 cut percutaneous tenotomy procedure. Method. All patients who underwent a percutaneous tendo-achilles release performed between June 2007 and October 2008 were identified through the clinical coding department and theatre log books. Their clinical notes were reviewed until discharge. Patients who were diabetic or had a foot deformity secondary to neurological complications were excluded. Results. 40 percutaneous tendo-achilles releases were performed in 38 patients, with an average age of 51 (male:female ratio 5:33). 37 were performed in combination with forefoot procedure. 36 were mobilized full weight bearing in a heel weight bearing shoe post operatively, of which 8 developed symptomatic over lengthening of the Achilles tendon at a mean of 7 months (2-15) post-operatively. Of these 7 required surgical treatment in the form of Achilles shortening. Conclusion. We no longer perform percutaneous Achilles tendon lengthening in neurologically normal patients, due to our concern regarding the risk of over lengthening. We now prefer to perform an open gastrocnemius lengthening
