RESUMO
Diabetes (DM) increases fracture risk, and bone quality depends on type diabetes type, duration, and other comorbidities. Diabetes is associated with a 32% increased relative risk (RR) of total fractures and 24% increased RR of ankle fractures compared with patients without DM. Type 2 DM is associated with a 37% increased RR of foot fractures compared with patients without DM. The incidence of ankle fractures in the general population is 169/100,000 per year, while foot fractures occur less frequently, with an incidence of 142/100,000 per year. Biomechanical properties of bone are negatively impacted by stiff collagen, contributing to the increased risk of fragility fractures in patients with DM. Systemic elevation of proinflammatory cytokines, such as tumor necrosis factor-alpha (TNFα), interleukin-1ß (IL-1ß), and interleukin 6 (IL-6), impact bone healing in patients with DM. Fractures in patients with DM, can be associated with poorly regulated levels of RANKL (receptor activator of nuclear transcription factor kappa-b ligand) leading to prolonged osteoclastogenesis, and net bone resorption. One of the most salient factors in treating fractures and dislocations of the foot and ankle is to recognize the difference between patients with uncomplicated and complicated DM. Complicated diabetes is defined as 'end organ damage', and for the purposes of this review, includes patients with neuropathy, peripheral artery disease (PAD) and/or chronic renal disease. Uncomplicated diabetes is not associated with 'end organ damage'. Foot and ankle fractures in patients with complicated DM pose challenges, and surgery is associated with increased risks of impaired wound healing, delayed fracture healing, malunion, infection, surgical site infection, and revision surgery. While patients with uncomplicated DM can be treated like patients without DM, patients with complicated DM require close follow-up and robust fixation methods should be considered to withstand the anticipated prolonged healing period. The aims of this review are as follows: (1) to review pertinent aspects of DM bone physiology and fracture healing, (2) to review the recent literature on treatment of foot and ankle fractures in patients with complicated DM, and (3) to provide treatment protocols based on the recent published evidence.
RESUMO
We report one- and 2-year results of a prospective, 5-year, multicenter study of radiographic, clinical, and patient-reported outcomes following triplanar first tarsometatarsal arthrodesis with early weightbearing. One-hundred and seventeen patients were included with a mean (95% confidence interval [CI]) follow-up time of 16.6 (15.5, 17.7) months. Mean (95% CI) time to weightbearing in a boot walker was 7.8 (6.6, 9.1) days, mean time to return to athletic shoes was 45.0 (43.5, 46.6) days, and mean time to return to unrestricted activity was 121.0 (114.5, 127.5) days. There was a significant improvement in radiographic measures with a mean corrective change of -18.0° (-19.6, -16.4) for hallux valgus angle, -8.3° (-8.9, -7.8) for intermetatarsal angle and -2.9 (-3.2, -2.7) for tibial sesamoid position at 12 months (n = 108). Additionally, there was a significant improvement in patient-reported outcomes (Visual Analog Scale, Manchester-Oxford Foot Questionnaire, and Patient-Reported Outcomes Measurement Information System) and changes were maintained at 12 and 24 months postoperatively. There was 1/117 (0.9%) reported recurrence of hallux valgus at 12 months. There were 16/117 (13.7%) subjects who experienced clinical complications of which 10/117 (8.5%) were related to hardware. Of the 7/117 (6.0%) who underwent reoperation, only 1/117 (0.9%) underwent surgery for a nonunion. The results of the interim report of this prospective, multicenter study demonstrate favorable clinical and radiographic improvement of the HV deformity, early return to weightbearing, low recurrence, and low rate of complications.
RESUMO
Refractory pain to the fourth and fifth tarsometatarsal (TMT) joint can be a source of disability and functional impairment. While pain has been attributed to injury, post-traumatic arthritis, arthrofibrosis, the principal causes of pain in the absence of arthritis are not well elucidated. The purpose of this study is to characterize arthroscopic pathology associated with chronic refractory pain to the fourth and fifth TMT joints. We retrospectively examined 24 patients that underwent arthroscopic surgery of the fourth and fifth TMT joints for refractory pain at our academic institution between 2015 and 2019. We used the Outerbridge classification for chondral lesions, the Kellgren Lawrence radiographic classification for osteoarthritis, and described intraarticular pathologies as acute hypertrophic synovitis, chronic synovial fibrosis, hyaline bands, meniscoid bodies, loose joint bodies, arthrofibrosis. Approximately, 31 of 45 TMT joints (68.9%) presented with radiographic evidence of arthritis. Approximately, 14 of 45 TMT joints (31.11%) were absent of radiographic signs of arthritis. The frequency of soft tissue pathology seen in these patients without radiographic evidence of arthritis was arthrofibrosis (87.5%), chronic synovial fibrosis (75.0%), and acute hypertrophic synovitis (62.5%). This is the first study to report arthroscopic pathologies associated with refractory pain to the fourth and fifth TMT joints.
RESUMO
Necrotizing fasciitis is a condition associated with high morbidity and mortality unless emergent surgery is performed. This study aims to understand the hospital course of diabetic and nondiabetic patients managed for lower-extremity necrotizing fasciitis by identifying factors contributing to readmissions and reoperations. About 562 patients treated for lower-extremity necrotizing fasciitis were selected from the American College of Surgeons-National Surgical Quality Improvement Program database between 2012 and 2017. The unplanned reoperation and readmission rates for all patients during the 30-day postoperative period were 9.4% and 5.3%, respectively. Out of 562 patients with lower-extremity necrotizing fasciitis, 326 (58.0%) patients had diabetes. Diabetes patients were more likely to undergo amputation (p < .00001). Neither readmission (6.1% vs 4.2%, p = .411) nor reoperation (8.6% vs 10.6%, p = .482) were significantly different between patients with and without diabetes. Neither readmission (7.2% vs 4.0%, p = .159) nor reoperation (4.1% vs 3.7%, p = .842) were significantly different between patients undergoing amputation and nonamputation procedures. In simple logistic regression, factors associated with unplanned reoperation included poorer renal function, thrombocytopenia, longer duration of surgery, longer hospital length of stay, postoperative surgical site infection, postoperative respiratory distress, and postoperative septic shock. Body mass index >30 kg/m2 was associated with decreased odds of readmission. In multiple logistic regression, surgical site infection was the only predictor of reoperation (adjusted odds ratio 7.32, 95% confidence interval 2.76-19.1), and any amputation was associated with readmission (adjusted odds ratio 4.53, 95% confidence interval 1.20-29.6). Further study is needed to understand patient characteristics to better direct management. However, the current study elucidates patient outcomes for a relatively rare condition.

Patients with diabetes mellitus that undergo ankle fracture surgery have higher rates of postoperative complications compared to patients without diabetes mellitus. We evaluated the rate of complications in insulin-dependent diabetes mellitus patients, non-insulin-dependent diabetes mellitus patients, and patients without diabetes in the 30-day postoperative period following ankle fracture surgery. We also analyzed hospital length of stay, unplanned readmission, unplanned reoperation, and death. Patients who underwent operative management for ankle fractures between 2012 and 2016 were identified in the American College of Surgeons National Surgical Quality Improvement Program® database using Current Procedural Terminology codes. Multiple logistic regression was implemented. Adjusted odds ratios were calculated along with the 95% confidence interval. A total of 19,547 patients undergoing ankle surgery were identified from 2012 to 2016. Of these patients, 989 (5.06%) had insulin-dependent diabetes mellitus, 1256 (6.43%) had noninsulin-dependent diabetes mellitus, and 17,302 (88.51%) did not have diabetes mellitus. Compared to patients without diabetes, patients with insulin-dependent diabetes mellitus had significantly greater adjusted odds of superficial surgical site infections, deep surgical site infections, osteomyelitis, wound dehiscence, pneumonia, unplanned intubation, mechanical ventilation, urinary tract infection, cardiac arrest, bleeding requiring transfusion, sepsis, hospital length of stay, unplanned readmission, unplanned reoperation, and death following ankle fracture surgery. We demonstrate that insulin-dependent diabetes mellitus is a strong predictor of 30-day postoperative complications, unplanned readmission, unplanned reoperation, and death following ankle fracture surgery.

Open reduction internal fixation (ORIF) is an accepted treatment for displaced tarsometatarsal joint (TMTJ) fracture dislocations. In general, hardware is routinely removed after 4 months to allow restoration of joint motion and avoid complications of hardware failure. Because few studies report outcomes of TMTJ fractures with retained hardware, there is little consensus regarding the optimal time for hardware removal or if hardware retention leads to adverse outcomes. We retrospectively reviewed the radiographic outcomes of retained hardware after ORIF of TMTJ fractures/dislocations in 61 patients. The mean age at the time of operation was 37.3 ± 14.9 years. ORIF was performed with 3.5 fully threaded cortical screws. Assessment of clinical and radiographic results was performed at 2 weeks, 6 weeks, 3 months, 6 months, and 12 months after surgical treatment. Out of the 61 patients that were included in this study, only 2 demographic variables demonstrated a trend for an adverse outcome. Older age correlated with lost reduction and elevated body mass index correlated with hardware failure. The presence of diabetes was correlated with an increased risk of postoperative infection but not hardware failure. During our follow-up period there were 49 patients (80.3 %) without failure of fixation. In conclusion, our study suggests that routine removal of hardware following open reduction and internal fixation of Lisfranc injuries in patients may not be necessary.

Displaced intra-articular calcaneal fractures are severe, complex injuries that can cause significant long-term functional impairment. Despite the controversies of whether these fractures should be treated operatively or nonoperatively, functional improvement can be seen with confounding variables that can be controlled by the surgeon. This article reviews prognostic factors that are associated with good functional outcomes following operatively treated displaced intra-articular calcaneal fractures.

Malreduction of distal tibiofibular syndesmosis (DTFS) leads to poor functional outcomes after ankle fracture surgery. Difficulty achieving anatomic alignment of the syndesmosis is due to variable morphology of the fibular incisura of the tibia and a paucity of literature regarding its morphologic characteristics. We surveyed 775 consecutive ankle computed tomography (CT) scans performed from June 2008 to December 2011, and 203 (26.2%) were included for evaluation. Two observers performed quantitative measurements and qualitative evaluated fibular incisura morphology. Tang ratios for fibular rotation, anterior and posterior tibiofibular distances, fibular incisura depth, and subjective morphologies on CT were assessed using conventional multiplanar reconstruction (MPR) and maximum intensity projections (MIPs). On conventional CT, the mean Tang ratio was 0.97 ± 0.06; the mean anterior tibiofibular distance was 2.17 ± 0.87 mm; the mean posterior tibiofibular distance was 3.52 ± 0.94 mm; and the mean depth of fibular incisura was 3.29 ± 1.19 mm. Five morphologic variations of the fibular incisura were identified: crescentic, trapezoid, flat, chevron, and widow's peak. The most common fibular incisura morphology was crescentic (61.3%), followed by trapezoid shape (25.1%); the least common morphology was flat (3.1%). Interobserver variability with intraclass correlation coefficient (ICC) was slightly higher for all quantitative measures on MPR (ICCâ¯=â¯0.72 to .81) versus MIP (ICCâ¯=â¯0.64 to 0.75). ICC for incisura shape and depth assessments was poor on both modalities (0.13 to 0.38). This comprehensive CT study reports on quantitative and qualitative descriptive measures to evaluate fibular incisura morphologies and fibular orientation. It also defines the frequency of DTFS measures and the interobserver performance on 2 CT evaluation methods.

Magnetic resonance imaging (MRI) is a noninvasive modality of choice for the detection of static peroneal tendon pathologic features. The depiction of peroneal tendon subluxation using real-time kinematic MRI has not been previously reported. We describe the MRI and intraoperative correlation of peroneal tendon and retinacular pathologic findings, and the novel use of kinematic MRI in the illustration of peroneal tendon subluxation.
