Background and objectives: The purpose of this retrospective study was to compare the clinical and radiological outcomes of patients who underwent biplane chevron medial malleolar osteotomy (MMO) for osteochondral lesions of the talus (OLT), fixed with either magnesium (Mg) or titanium (Ti) screws. Materials and Methods: A total of 22 patients (12 male, 10 female) with a mean age of 40.6±12.5 years (range, 18-56 years) who underwent MMO for OLT treatment were included in this retrospective study. Of the 22 patients, MMO was fixed with bioabsorbable Mg screws (Alloy: MgYREZr) in 11 patients, and in the remaining 11 patients (one bilateral) MMO were fixed with Ti screws.  All patients were followed up for at least one year with a mean of 20.7±8.9 months (range, 12–49 months). The American Orthopedic Foot and Ankle Society (AOFAS) scale and the visual analog scale (VAS) were used to evaluate the clinical results. Union of the osteotomy, postoperative displacement, and all other complications were followed and analyzed. Results: An improvement in the AOFAS scale and VAS points were recorded in both groups with no statistically significant difference between the groups (p: 0.079 and 0.107 respectively). Complete union of the osteotomy was obtained in all patients. One patient in the Ti group required implant removal due to pain and irritation. There were no other significant complications in either group. Conclusions: The results of this study showed that bioabsorbable Mg compression screws have similar therapeutic efficacy to Ti screws in respect to functional and radiological outcomes in MMO fixation. Bioabsorbable Mg screw is an alternative fixation material which can be safely used for MMO in ankle surgery.

Objective Osteochondral lesions of the talus are common injuries, with one of the leading treatment options being the M-BMS (matrix-augmented bone marrow stimulation) + I/III collagen scaffold. Osteotomy of the medial malleolus is not unusual but presents the risk of malunion or irritation by hardware. The aim of the study was to analyze data from the German Cartilage Society (Knorpelregister DGOU) to evaluate the influence of medial malleolar osteotomy on clinical results of M-BMS + I/III collagen scaffold. Design The ankle module of the Cartilage Register includes a total of 718 patients, while 45 patients met the inclusion criteria. Patients were treated with an M-BMS + I/III collagen scaffold of the medial talus, 30 without and 15 with an osteotomy of the medial malleolus. The follow-up evaluations included FAAM (Foot and Ankle Ability Measure), FAOS (Foot and Ankle Outcome Score), and VAS (visual analogue scale). Results Forty-five patients (22 male, 23 female) aged between 18 and 69 years (mean: 34 years) were included in this study. Between preoperative and 12 months postoperative, we noted a significant improvement in FAAM-ADL (Activity of Daily Living) ( P = 0.004) as well as FAOS-Pain ( P = 0.001), FAOS-Stiffness ( P = 0.047), FAOS-ADL ( P = 0.002), FAOS-Sport ( P = 0.001), and FAOS Quality of Life ( P = 0.009). There was no significant difference between patients who underwent an osteotomy or not. Conclusion The results show a significant improvement in patients’ outcome scores following a M-BMS + I/III collagen scaffold. No statistical difference was noted among those undergoing medial malleolar osteotomy.

Objective. The purpose of this retrospective study was to compare the clinical and radiological results of magnesium versus titanium screw fixation for modified distal chevron osteotomy in hallux valgus (HV). Materials and Methods. A total of 31 patients who underwent modified distal chevron osteotomy for HV deformity between 2014 and 2017 were reviewed retrospectively. Headless magnesium (Mg) compression screw fixation was applied in 16 patients (17 feet) and headless titanium (Ti) compression screw in 15 patients (17 feet). Patients were followed up for at least 12 months with a mean of 19.0 ± 6.8 months in the Mg screw group and 16.2 ± 6.19 in the Ti screw group, respectively (p: 0.234). Clinical results were evaluated using the American Orthopedic Foot and Ankle Society Hallux metatarsophalangeal-interphalangeal (AOFAS-MTP-IP) scale and a visual analogue scale (VAS). The hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured before and after surgery. Time to osteotomy union and any complications were recorded and compared between the groups. Results. An improvement in the AOFAS-MTP-IP scale and VAS points were recorded in both groups with no statistically significant difference between the groups (p: 0.764 and 0.535, resp.). At the final follow-up examination, HVA and IMA were similar (p: 0.226 and 0.712, resp.). There was no significant loss of correction between the early and final radiographs in respect of HVA and IMA in both groups (p: 0.321 and p: 0.067). Full union of the osteotomy was obtained in all patients. Prolonged (1.5 months) swelling and mild hyperemia around the surgical incision were observed in 1 patient in the Mg group but there was a good response to physical and medical therapy, and the complaints were completely resolved. There were no other significant complications in either group. Conclusion. The results of this study showed that bioabsorbable Mg compression screw fixation has similar therapeutic efficacy to Ti screw fixation in respect of functional and radiological outcomes. Bioabsorbable Mg screw is an alternative fixation material that can be safely used for modified distal chevron osteotomy in HV surgery.

AbstractAlthough prophylaxis for venous thromboembolism (VTE) is recommended after many surgeries, evidence base for use of VTE prophylaxis after foot or ankle surgery has been elusive, leading into varying guidelines recommendations and notable practice variations. We conducted a systematic review of the literature to determine if use of VTE prophylaxis decreased the frequency of subsequent VTE, including deep vein thrombosis (DVT) or pulmonary embolism (PE), compared with control. We searched PubMed, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov through May 2018, for randomized controlled trials (RCTs) or prospective controlled observational studies of VTE prophylaxis in patients undergoing foot and ankle surgery. Our search retrieved 263 studies, of which 6 were finally included comprising 1,600 patients. Patients receiving VTE prophylaxis had lower risk for subsequent DVT (risk ratio [RR]: 0.72; 95% confidence interval [CI]: 0.55–0.94) and subsequent VTE (RR: 0.72; 95% CI: 0.55–0.94). There was only one case of nonfatal PE, no cases of fatal PE, and no change in all-cause mortality (RR: 3.51; 95% CI: 0.14–84.84). There was no significant difference in the risk for bleeding (RR: 2.12; 95% CI: 0.53–8.56). Very few RCTs exist regarding the efficacy and safety of VTE prophylaxis in foot and ankle surgery. Prophylaxis appears to reduce the risk of subsequent VTE, but the event rates are low and symptomatic events are rare. Future studies should determine the subgroups of patients undergoing foot or ankle surgery in whom prophylaxis may be most useful.

Background: The rate of surgical site infections (SSIs) after foot or ankle surgery remains high, despite the implementation of antibiotic prophylaxis. Recently, guidelines suggest a single dose of 2 g instead of 1 g of cefazolin for implant surgery; this decision is largely based on pharmacokinetic studies. However, the clinical effect of this higher dose has never been investigated in foot and ankle surgery. This retrospective cohort study investigated the effect of 2 g compared with 1 g of prophylactic cefazolin on the incidence of SSIs in foot and ankle surgery. Methods: All patients undergoing trauma-related surgery of the foot, ankle, or lower leg between September 2015 and March 2019 were included. The primary outcome was the incidence of an SSI. SSIs were compared between patients receiving 1 g and 2 g of cefazolin as surgical prophylaxis, using a propensity score to correct for possible confounders. Results: A total of 293 patients received 1 g and 126 patients received 2 g of cefazolin. The overall number of SSIs was 19 (6.5%) in the 1-g group and 6 (4.8%) in the 2-g group. Corrected for possible confounders, this was not statistically significant (OR, 0.770; P = .608). Conclusion: Even though the decrease in SSI rate from 6.5% to 4.8% was found not to be statistically significant, it might be clinically relevant considering the reduction in morbidity, mortality, and healthcare costs. Research linking pharmacokinetic and clinical results of prophylactic cefazolin is needed to establish whether or not the current recommendations and guidelines are sufficient for preventing SSIs in foot and ankle surgery. Level of Evidence: Level III, retrospective comparative series.

Background. Finding the right diagnoses in patients with complex foot and ankle disorders can be challenging. Single-photon emission computed tomography and computed tomography (SPECT-CT) has shown to be feasible in foot and ankle surgery. The aim of this study was to evaluate the reliability and accuracy of SPECT-CT and thereby its impact on final treatment decision compared with magnetic resonance imaging (MRI). Methods. A retrospective study was performed on 49 patients treated at our institution. Experienced foot and ankle surgeons independently, and blinded, analyzed clinical data and radiographs together with MRI, SPECT-CT, or a combination of both. Based on the determined final treatment decision Cohen’s kappa values were calculated to illustrate interrater and intrarater reliability. Results. The kappa values for interrater reliability were higher for SPECT-CT at .68 and MRI + SPECT-CT at .71 compared to 0.38 for MRI alone (P < .05). The kappa values for intrarater reliability of MRI + SPECT-CT were higher at .75 compared with SPECT-CT alone at .67 (P < .05) and MRI at .35 (P < .01). Conclusion. We found a higher interrater and intrarater reliability for SPECT-CT compared with MRI alone for diagnosing complex foot and ankle pathologies. SPECT-CT has a high impact on final treatment decision. The main indications are bony pathologies with diagnostic uncertainty especially in closely adjacent structures as the joints of the midfoot, occult coalitio, stress fractures, verification or exclusion of nonfusion, periprosthetic disorders after total ankle replacement and osteochondral lesion in cases of combined pathologies.

Category: Midfoot/Forefoot Introduction/Purpose: To compare the clinical result of midfoot and metatarsal dorsal wedge osteotomy for the treatment of cavovarus foot deformity in adolescents. Methods: A comparative retrospective study of 24 patients with cavovarus foot deformity in adolescents was conducted between March 2012 and March 2015 in the Guangzhou Orthopaedic Hospital. All patients were flexible deformity. 10 patients were treated with midfoot dorsal wedge osteotomy, while 14 patients received metatarsal dorsal wedge osteotomy. The clinical curative effects, complications and image differences were compared between the two groups. American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Visual Analogue Scale (VAS) score were evaluated for each patient during the follow-up. All statistics were analyzed using the SPSS software system. Results: No early stage soft tissue complications occurred in all patients. All the patients obtained an average 21.5 months (ranged,10-30 months) follow-up.X-ray demonstrated that bone healing was obtained, the midfoot dorsal wedge osteotomy group at an average of 11.2 weeks (ranged,10-13 weeks). the metatarsal dorsal wedge osteotomy group at an average of 13.4 weeks (ranged,12-15 weeks). By AOFAS foot score and VAS pain score: There is no significant difference between the two groups (P=0.138). No complications of nonunion, recurrence of de-fortuity or implant failure were seen during follow-up. Conclusion: The midfoot and metatarsal dorsal wedge osteotomy are the effective methods for the treatment of cavovarus foot deformity in adolescents. For severe deformity midfoot metatarsal dorsal wedge osteotomy can provide more powerful correction.

BackgroundRectal biopsy for the diagnosis for Hirschsprung's disease (HD) can be performed in several ways. Suction rectal biopsy (SRB) is the most widely used method for neonates and younger infants while open strip biopsy (OSB) is reserved for older children. Current notions suggest that SRB should not be used in older infants due to perceived thicker fibrous tissue in their rectal walls leading to higher rates of inconclusive results. This study aims to compare the inconclusive rates of both methods in children of different age groups.MethodsA retrospective study were carried out with patients aged 13 years who underwent SRB or OSB during a 4-year period in a single center. Rectal biopsies were performed on patients with HD with previous endorectal pull-through surgeries excluded. Primary outcomes were rates of inconclusive results for SRB and OSB overall and when divided into different age groups.Results79 biopsies (57 SRB and 22 OSB) were included in the study. 12 biopsies (9 SRB and 3 OSB) were deemed inconclusive. There was no significant difference in the rate of inconclusive results between patients underwent SRB and OSB overall (15.8% vs 13.6%, p=1.000). The same results were obtained when patients were divided into under one year and over one year groups or other different age groups (30.0% vs 33.3%, p=1.000).ConclusionsDespite low biopsy numbers, our study suggests that SRB provides comparable rates of inconclusive results with OSB in children of all age groups.

Category: Hindfoot Introduction/Purpose: Elongation of the lateral column is indicated only in patients who have a flexible deformity Stage 2B of flat foot. The Evans osteotomy is performed 1.5 or 2 cm from the cuboideal calcaneal joint, and in many publications is maintained by different kind of devices. Our hypothesis is that Evans osteotomy, with blocked plates with a wedge block, without the use of bone graft, maintain the correction obtained at one year after surgery. The primary objective was to evaluate the radiological results at the postoperative year of the osteotomy Secondary objectives were to evaluate the persistence of the correction obtained between the 3 months and the year of the postoperative period and to evaluate the functional outcomes with AOFAS score. Methods: We studied a total of 12 patients, 14 feet. with stage 2 B flat foot, in all cases surgery was performed by the same specialist between March of 2011 and March of 2014 in the Service of foot and ankle of our institution. Inclusion criteria were: patients with type 2B flat foot, submitted to external column elongation, with plates blocked with a 6 to 10 mm wedge block, without the use of bone grafting, minimum follow-up of 1 year. Exclusion criteria: revision of previous surgery, another type of material used for elongation of the external column, neurological sequelae. The study was performed retrospectively through clinical records database, data collection and measurements were performed by 2 second-year Foot and ankle fellow trained in the same institution. Statistical analysis was performed with the T-student test. Results: A total of 12 patients / 14 feet were evaluated during the study period, with a diagnosis of flatfoot type 2B. The average age was 57 years (32-65 years), 11 (78.5%) were female. No statistically significant difference was observed in any of the radiographic variables measured, at 3 months and at 12 months postoperatively. The preoperative AOFAS score, was 54 points. At the first year was 93 points. Consolidation was achieved at 3 months in all cases. The complications found were 2 superficial infections and 1 wound dehiscence. As a late complication, there was only 1 case of cuboidal calcaneal osteoarthritis that did not require surgical resolution. Conclusion: Evans osteotomy for elongation of the external column provides a reproducible and reliable method to restore the normal functional stability of the midfoot and hindfoot. According to the results obtained in our work, we can conclude that the blocked plates with a wedge lock manage to preserve the corrections obtained with the Evans osteotomy in patients with type IIB flat foot. There is no need of autograft with the consequent risk of comorbidities produced by a second approach to the grafting as well as the complications that could happen with the use of allografts.

Three hundred foot and ankle bone grafts were reviewed in three separate series of 100 consecutive grafts from two institutions. The series represent a period from 1977 to 1990 and demonstrate treatment patterns that varied over time and between institutions in indications, graft material, and perioperative management. Over 42% of the 300 grafts were for calcaneal osteotomies; most were Evans calcaneal osteotomies. Over 72% of the grafts were allogeneic bone-bank bone, which performed well in calcaneal osteotomies and for packing of defects. Upon review of the incidence of bone complications, no significant differences were observed between surgical procedures that used autogenous versus allogeneic grafts. However, four out of six failures of first metatarsal repair were with allogeneic bone. There was a significant difference in complication rates for the major indications for bone-graft surgery. Nonunions and arthrodeses resulted in higher complication rates than expected, whereas calcaneal osteotomies resulted in a lower complication rate than expected.
