Aim: The aim of this study was to investigate the health-related quality of life of Spanish outpatients with diabetic foot ulcer using the Diabetic Foot Scale-Short Form (DFS-SF)., Materials and Methods: This cross-sectional observational study included 141 outpatients with diabetic foot ulcers (DFU). The DFS-SF was applied in personal interviews conducted by a trained investigator to assess health-related quality of life (HRQoL)., Results: The domain related to "worried about ulcers" had the lowest in score [50 (27.5-65.0)], and the highest score was in the physical health domain [76 (60.0-88.0)]. There was a statistically significant difference in the ulcer type and the physical health subscale, finding the lowest values in the physical health subscale in patients with ischaemic diabetic foot ulcers [58 (39.0-70.0), p = 0.007]. In the multivariable analysis the domains Leisure (OR 0.98, 95% CI 0.97-0.99) and worried about ulcers/feet (OR 0.98, 95% CI 0.96-0.99) were identified as significant independent domains in patients with the experience of a previous minor amputation. A significant negative correlation was observed between the SINBAD DFU score and leisure (r = -0.181, p = 0.032), physical health (r = -0.202, p = 0.016), dependence/daily life (r = -0.232, p = 0.006), and the "bothered by ulcer care" (r = -0.239, p = 0.004) domains of the DFS-SF. The ulcer duration had a significant negative correlation with all the domains of DFS-SF., Conclusion: The DFS-SF survey is a specific instrument that could be implemented in diabetic foot units as part of the management of patients with DFU to evaluate HRQoL. The domain of "worried about ulcers" had the lowest score in our population suggesting that clinicians should try to work on the emotional state of patients with DFU. The mean duration of DFU was the most influential factor related to worse scores followed by previous amputations. The SINBAD score had significant negative correlations suggesting that HRQoL may be related to the severity of DFU in this study population., Competing Interests: Declaration of competing interest There are no relevant conflicts of interest to disclose., (Copyright © 2023.

Background: Therapeutic footwear becomes the first treatment line in the prevention of diabetic foot ulcer and future complications of diabetes. Previous studies and the International Working Group on the Diabetic Foot have described therapeutic footwear as a protective factor to reduce the risk of re-ulceration. In this study, we aimed to analyze the efficacy of a rigid rocker sole to reduce the recurrence rate of plantar ulcers in patients with diabetic foot., Methods: Between June 2016 and December 2017, we conducted a randomized controlled trial in a specialized diabetic foot unit., Participants and Intervention: Fifty-one patients with diabetic neuropathy who had a recently healed plantar ulcer were randomized consecutively into the following two groups: therapeutic footwear with semi-rigid sole (control) or therapeutic footwear with a rigid rocker sole (experimental). All patients included in the study were followed up for 6 months (one visit each 30 ± 2 days) or until the development of a recurrence event., Main Outcome and Measure: Primary outcome measure was recurrence of ulcers in the plantar aspect of the foot., Findings: A total of 51 patients were randomized to the control and experimental groups. The median follow-up time was 26 [IQR-4.4-26.1] weeks for both groups. On an intention-to-treat basis, 16 (64%) and 6 (23%) patients in the control and experimental groups had ulcer recurrence, respectively. Among the group with >60% adherence to therapeutic footwear, multivariate analysis showed that the rigid rocker sole improved ulcer recurrence-free survival time in diabetes patients with polyneuropathy and DFU history (P = 0.019; 95% confidence interval, 0.086-0.807; hazard ratio, 0.263)., Conclusions: We recommend the use of therapeutic footwear with a rigid rocker sole in patients with diabetes with polyneuropathy and history of diabetic foot ulcer to reduce the risk of plantar ulcer recurrence., Trial Registration: ClinicalTrials.gov NCT02995863., Competing Interests: The authors have declared that no competing interests exist.

Although exostectomy for chronic midfoot plantar ulcers in Charcot foot is apparently effective, with healing rates of nearly 75%, a subset of patients develop recurrent ulceration and show an unstable foot position, especially after undergoing exostectomy confined to the lateral column. The reasons for this failure have not been investigated. The main objective of this study was to evaluate the early changes in radiographic alignment after an exostectomy in patients with Charcot neuropathic osteoarthropathy (rocker bottom) and plantar ulcer located in the lateral column. The present study evaluated retrospectively changes in radiographic alignment after an exostectomy in 12 Charcot feet (rocker bottom) with plantar ulcer located in the lateral column. Indication for plantar exostectomy was the treatment of ulcer affected by osteomyelitis. We evaluated the early changes in the alignment of the foot on weight-bearing lateral radiographs 6 months after exostectomy. Paired sample Wilcoxon test was used to calculate the differences between preoperative and postoperative measurements. Furthermore, the relationship between revision surgery and early changes in radiographic angular measurements was determined by using the Mann-Whitney U test. After exostectomy, the inclination of the calcaneal bone decreased ( P = .003; r = 0.849) and declination of talus bone increased ( P = .041; r = 0.589). The change in calcaneal inclination was associated with revision surgery ( P = .042; r = 0.586). The present case series demonstrates that exostectomy procedure for the lateral column in patients with Charcot foot results in radiological changes in the hindfoot over the sagittal plane. The inversion of the calcaneal pitch angle suggests the possibility of further adverse events and the need for revision surgery.

The aim of this article was to assess the ability to predict reulceration in people with diabetes and a history of minor amputation according to the formula proposed by Miller et al. A retrospective study was performed on 156 consecutive records of patients with a recent history of simple or multiple forefoot amputation. The sample was divided according to Miller's formula into patients at low risk of reulceration and those at high risk; those were further divided into two subgroups according to whether or not the first segment of the forefoot had been amputated. Forty-eight (47·1%) individuals suffered forefoot reulceration, showing a median reulceration-free survival time of 8 months [interquartile range (IR) 3·6-14·8]. Nephropathy (P = 0.005) and Miller's formula (P = 0.028) were risk factors for reulceration-free survival time in the univariate analysis. The pattern relating to the first segment amputated [hazard ratio (HR) 2·853; P = 0·004; 95% confidence interval (CI) 1·391-5·849] and nephropathy (HR 2·468; P = 0.004; 95% CI 1.328-4.587) showed a significant hazard ratio in the multivariate Cox model. Participants with first segment amputation and one other amputation showed an association with the probability of reulceration in comparison with any other specific type of minor amputation., (© 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.)

Aims: To stratify the ulceration risk according to the foot morphology in people with diabetes and a history of forefoot neuropathic ulceration., Methods: A cross-sectional study was performed on 139 neuropathic individuals with diabetes and previous forefoot ulcers between January 2012 and February 2014. Foot position of the participants was evaluated by using the foot-posture index. A multivariate analysis adjusted for confounding variables was performed with the ulceration risk factors that were found in the univariate analysis., Results: Two hundred and fifty-eight feet were analysed, 104 (40.3%) feet had a history of ulceration on the forefoot and 154 (59.7%) feet had no previous ulceration. Two positive tests of neuropathy (p<0.001; CI[1.961-6.249] OR 3.500), presence of deformities (p=0.043; CI[1.020-3.599] OR 1.916) and foot type (p=0.039) showed an association with ulceration risk in multivariate analyses. Pronated feet showed a higher risk of ulceration than supinated feet (p=0.011; CI[1.253-5.708] OR 2.675), while significant differences between neutral and supinated feet were not found (p=0.221; CI[0.719-2.753] OR 1.476)., Conclusions: A pronated foot has a higher risk of ulceration on the forefoot in neuropathic people with deformities and diabetes mellitus. Foot type should be evaluated in people at risk of ulceration., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Foot ulcer recurrence is still an unresolved issue. Although several therapies have been described for preventing foot ulcers, the rates of reulcerations are very high. Footwear and insoles have been recommended as effective therapies that prevent the development of new ulcers; however, the majority of studies have analyzed their effects in terms of reducing peak plantar pressure rather than ulcer relapse. Knowledge of biomechanical considerations is low, in general, in the team approach to diabetic foot because heterogeneous professionals having competence in recurrence prevention are involved. Assessment of biomechanical alterations define a foot type position; examining foot structure and recording plantar pressure could help in appropriate insole and footwear prescription and design. Patient education and compliance should be taken into consideration for better therapy success. When patients suffer from rigid deformities or have undergone an amputation, surgical offloading should be considered as an alternative., (© The Author(s) 2014.)

Our aim was to identify the optimal diagnostic cutoff point on the scale of protrusion measurements of the first metatarsal (M1) to predict the probability of reulceration after metatarsal head resection in patients with diabetes mellitus. We conducted a prospective study of patients with diabetes who underwent resection of at least 1 metatarsal head in our department. After surgery, we measured the difference in length (protrusion) between the M1 and the longest of the 4 lesser metatarsals by radiographic view. The patients were divided into those in whom the M1 was the longest of the 5 metatarsals (group 1) and patients in whom at least one of the lesser metatarsals was longer than the M1 (group 2). They were followed-up for 12 months and were assessed for reulceration. Ninety-one patients were included in the present study: 43 (47%) in group 1 and 48 (53%) in group 2. In group 1, the longer the protrusion of M1 was, the higher the probability for reulceration (P < .001, 95% confidence interval = 0.813-0.997). In group 2, the shorter the protrusion of M1, the higher the probability for reulceration (P = .002, 95% confidence interval = 0.628-0.905). The optimal cutoff point for group 1 was 11 mm (sensitivity = 84.6%, specificity = 86.7%) for the probability of reulceration. In group 2, it was -7 mm (sensitivity = 81.8%, specificity = 65.4%). These results suggest that M1 protrusion is an optimum prognostic indicator for reulceration and could be recommended for detecting patients at risk of reulceration after surgery.
