- Introduction: Fracture reduction and fixation of distal femur fractures are technically demanding. Postoperative malalignment is still commonly reported after minimally invasive plate osteosynthesis (MIPO). We evaluated the postoperative alignment after MIPO using a traction table with a dedicated femoral support. Methods: The study included 32 patients aged 65 years or older with distal femur fractures of all AO/OTA types 32 (c) and 33 (except 33 B3 and C3) and peri-implant fractures with stable implants. Internal fixation was achieved with MIPO using a bridge-plating construct. Bilateral computed tomography (CT) scans of the entire femur were performed postoperatively, and measurements of the uninjured contralateral side defined anatomical alignment. Due to incomplete CT scans or excessively distorted femoral anatomy, seven patients were excluded from analyses. Results: Fracture reduction and fixation on the traction table provided excellent postoperative alignment. Only one of the 25 patients had a rotational malalignment of more than 15 & DEG; (18 & DEG;). Conclusions: The surgical setup for MIPO of distal femur fractures on a traction table with a dedicated femoral support facilitated reduction and fixation, resulting in a low rate of postoperative malalignment, despite a high rate of peri-implant fractures, and could be recommended for surgical treatment of distal femur fractures.

- Quantitative gait analysis is a powerful tool for the assessment of a number of physical and cognitive conditions. Unfortunately, the costs involved in providing in-lab 3D kinematic analysis to all patients is prohibitive. Inertial sensors such as accelerometers and gyroscopes may complement in-lab analysis by providing cheaper gait analysis systems that can be deployed anywhere. The present study investigates the use of inertial sensors to quantify gait symmetry and gait normality. The system was evaluated in-lab, against 3D kinematic measurements; and also in-situ, against clinical assessments of hip-replacement patients. Results show that the system not only correlates well with kinematic measurements but it also corroborates various quantitative and qualitative measures of recovery and health status of hip-replacement patients

Tidskriftsartikel (refereegranskat)abstract
- Background: Restricted weight-bearing is still used after lower extremity fracture surgery in elderly patients. The long-term effect on gait recovery in elderly patients with distal femur fractures (DFF) and their ability to comply with the restrictive weight-bearing regime is unknown. This study aimed to investigate the effect of restricted postoperative weight-bearing on gait recovery (actual weight-bearing and cadence) during a 1-year follow-up. Methods: This study evaluated secondary outcomes from a randomized controlled trial (32 patients ≥65 years, with a traumatic DFF). Internal fixation was achieved using an anatomical lateral plate. Patients were allocated to either immediate full weight-bearing (FWB) or partial weight-bearing (PWB) (30% of body weight) for 8 weeks. Pressure-sensitive sensors (F-scan™ system, Tekscan, Massachusetts, USA) were used to measure weight-bearing and cadence postoperatively and at 8-, 16-, and 52-week follow-ups. Twenty-six patients with at least 1 measurement were included. Results: There was a statistically significant difference in actual weight-bearing between the PWB and FWB groups postoperatively of 32.3% (95% confidence interval CI, −50.0; −13.0, P <.001) and at the 8-week follow-up of 36.8% (95% CI −61.0; −18.0, P =.01), but not at later follow-ups. The PWB group presented a consistently lower cadence compared to the FWB group, which was statistically significant at the 16-week follow-up with 9.0 steps/min (95% CI -16.2; −1.1, P =.047) and 52-week follow-up with 9.3 steps/min (95% CI −18.0; −3.9, P =.009). Conclusions: Restricting postoperative weight-bearing in elderly patients with a DFF had a significant effect on postoperative weight-bearing. The effect lingered with a delayed return to FWB and persistent significantly lower cadence in the PWB group. These findings suggest that even temporary weight-bearing restrictions most likely have negative long-term effects on gait function at 1 year and, therefore, cannot be recommended.

Tidskriftsartikel (refereegranskat)abstract
- Background: The literature offers sparse information about foot anthropometrics in patients with diabetes related to foot length, foot width and toe height, although these measurements are important in shoe fitting. A poorly fitted shoe is one of many contributory factors in the development of diabetic foot ulcers. The purpose of this study was to describe the foot anthropometrics in groups of patients with diabetes, in groups representing the general population and to explore whether foot anthropometrics differ between patients with diabetes and the general population. Method: Foot anthropometrics (foot length, foot width and maximum toe height) was measured in 164 patients with diabetes, with and without neuropathy (n = 102 and n = 62 respectively). The general population was represented by 855 participants from two sources. Results: Foot length, foot width and toe height varied (220-305 mm; 82-132 mm and 15-45 mm respectively) in the diabetic group and in the group representing the general population (194-306 mm; 74-121 mm and 17-31 mm respectively). Age, gender and BMI influence the foot anthropometrics, however, when adjusting for theses variables the index foot length/width was lower (2.58) in patients with diabetes without neuropathy vs. controls (2.63), p = 0.018. Moreover, patients with diabetes with neuropathy had wider feet (98.6 mm) compared with the controls (97.0 mm), p = 0.047. Conclusions: The individual variations of foot length, foot width and maximum toe height were large. The impact of gender on foot anthropometrics was confirmed and the impact of age and BMI were shown. Patients with diabetes seemed to have a wider forefoot width and a lower foot length to foot width ratio compared to the controls.

Tidskriftsartikel (refereegranskat)abstract
- Background: The prevention and care of foot problems in diabetes begins with a risk classification. Today, the prosthetists and orthotists (CPO) and other health care professionals assess the risk of developing foot ulcers more or less subjectively. The objective of the study was to describe the construction of an eHealth tool, the D-Foot, which generates a risk classification. The reliability of the D-Foot was tested. Methods: The D-Foot includes 22 clinical assessments and four self-reported questions. The content validity was assured by expert group consensus and the reliability was assessed through an empirical test-retest study. Inter- and intra-rater reliability was calculated using patients referred to four departments of prosthetics and orthotics (DPO). Results: The agreement for the risk classification generated using the D-Foot was 0.82 (pooled kappa 0.31, varying from 0.16 to 1.00 at single DPOs). The inter-rater agreement was > 0.80 regarding the assessments of amputation, Charcot deformity, foot ulcer, gait deviation, hallux valgus/hallux varus and risk grade. The inter- and intra-rater agreements for the discrete measurements were > 0.59 and > 0.72 respectively. For continuous measurements, the inter- and intra-rater correlation varied (0.33-0.98 and 0.25-0.99 respectively). Conclusion: The D-Foot gave a reliable risk foot classification. However, there was a variation in the inter- and intra-rater reliability of the assessments included and refinements are needed for variables with low agreement. Based on the results, the D-Foot will be revised before it is implemented in clinical practice.

Tidskriftsartikel (refereegranskat)abstract
- Background: Non-removable knee-high devices are the gold standard to treat diabetic foot ulcers located on the plantar forefoot, but they immobilize the ankle, which restricts daily life activities and has negative effects on joint functioning. Objective: To investigate the feasibility of sealing a therapeutic shoe to off-load and heal diabetic forefoot ulcers. Design: A case series of seven men with type 2 diabetes and a metatarsal head ulcer were prescribed therapeutic shoes and custom-made insoles. The shoe was sealed with a plastic band. Off-loading was assessed with the F-scan pressure measurement system. Adherence to wearing the shoe was assessed with a temperature sensor and by documenting the status of the seal. Results: The off-loading was effective and all ulcers healed. Median time to healing was 56 days (range 8–160). Complications were secondary ulcer (n = 1) and plantar hematoma (n = 1). Five of seven participants did not disturb the seal. Conclusions: Sealing a therapeutic shoe is a feasible way to off-load and heal forefoot ulcers. A controlled trial is needed to compare the effectiveness and safety of a sealed shoe to other non-removable devices. © 2017 The Author(s).

Konferensbidrag (refereegranskat)abstract
- Aim: The aim was to investigate the feasibility of using a therapeutic shoe, rendered irremovable,to off-load and heal forefoot ulcers. Non-removable knee-high off-loading devicesare gold standard to treat neuropathic forefoot ulcers. They do however immobilize theankle, affecting joint functioning and daily activities.Method: Seven men with diabetes type 2 since >10 years, sensory neuropathy and a metatarsalhead ulcer (table 1) were prescribed extra-depth therapeutic roller shoes and custom-madeinsoles adjusted to off-load the ulcer (fig. 1). Off-loading was assessed with anin-shoe plantar pressure system* measuring plantar peak pressures as the participantswalked. The shoe was then sealed with a plastic band and worn day and night like a cast.Adherence was assessed by documenting the status of the seal (intact/broken) whenchanging ulcer dressings.Results / Discussion: All ulcers healed, with a median time to healing of 8 weeks (range1-23). The median peak pressure on the ulcer was 116 kPa (range 62-192) when walkingwith the shoe. Five of seven participants respected the seal. Complications were secondaryulcer (n=1) and plantar hematoma (n=1). The most common complaint was difficulty todress (n=5).Sealed therapeutic shoes are an interesting avenue for future research; they include advantagesof non-removable knee-high devices as effective off-loading and high adherence,and overcome disadvantages as mobility restrictions and high costs.Conclusion: It seems feasible to seal a therapeutic shoe to off-load and heal forefoot ulcers.A randomized controlled trial is underway in which sealed shoes are to be comparedto total contact casting.

- BackgroundTherapeutic shoes can prevent diabetic foot reulcerations but their use is complicated by the fact that shoes have psychological and social meanings, which is believed to put a larger burden on women than men. The aim was to compare attitudes and attributes of women and men using therapeutic shoes for diabetic foot complications.MethodsA questionnaire was posted to 1230 people with diabetes who had been fitted with therapeutic shoes. Women's and men's answers were compared using t-tests, Mann-Whitney U tests and chi-square tests with Fischer's exact tests. P-values<0.05 were considered statistically significant.ResultsQuestionnaires from 443 (36.0%) respondents (294 men, 149 women, mean age 69.2years) were analyzed. More men than women (p<0.05) had paid employment (20.4% vs 9.4%), had someone who reminded them to wear their therapeutic shoes (27.6% vs 10.0%), and had a history of foot ulcers (62.9% vs 46.3%) or minor amputation (17.7% vs 6.7%). More women than men received disability pension (18.8% vs 10.2%). Women reported worse general health, lower internal locus of control regarding ulcer prevention, and more negative attitudes to the appearance and price of therapeutic shoes and how they felt about wearing them in public. Other comparisons were non-significant: other shoe attributes, education, diabetes type, current foot ulcers, major amputations, satisfaction with shoe services, understanding of neuropathy as a risk factor, locus of control regarding ulcer healing, belief in the shoes' efficacy to prevent and heal ulcers, worries about ulcer healing and new ulcerations, self-efficacy, depression, shoe use/adherence, paying a fee for therapeutic shoes, and social support.ConclusionsMen had worse foot complications. Women had worse general health, lower internal locus of control regarding ulcer prevention, and more negative attitudes toward therapeutic shoes. Clinicians should pay more attention to their female patients' concerns. Future research and development should focus on improving the weight and appearance of therapeutic shoes, particularly for women. Research is also needed on how to facilitate the adaption and reevaluation process where patients change from viewing shoes purely as items of clothing to also viewing them as medical interventions.

- Aims People at increased risk of developing diabetic foot ulcers often wear therapeutic footwear less frequently than is desirable. The aims were to identify patient groups prone to nonadherence to wearing therapeutic footwear and modifiable factors associated with adherence. Materials and methods A questionnaire was mailed to 1230 people with diabetes who had been fitted with therapeutic footwear. Independent variables were categorized into five domains. For each domain, variables that were associated with adherence in a univariate regression analysis were entered into a multiple regression analysis. Results A total of 429 (34.9%) questionnaires were analyzed. Multiple regression analyses showed significant associations (p < 0.05) between higher adherence and paid employment, current foot ulcer, previous foot ulcer, satisfaction with follow-up, self-efficacy, understanding of lost/reduced sensation as a risk factor for foot ulcerations, visible storage of therapeutic footwear at home, storage of conventional footwear out of sight, consistent choices about which footwear type to wear, and a belief that therapeutic footwear promotes ulcer healing. The five multivariate models explained 2-28% of the variance in adherence, with the strategies for footwear use domain explaining the most. Conclusions Patients without paid employment or without foot ulcer experience are more prone to nonadherence. To improve adherence, clinicians should advise patients to store therapeutic footwear in a visible place at home and put conventional footwear away and encourage patients' self-efficacy and habitual use of therapeutic footwear. Future studies should investigate this topic further and explore ways to promote changes in habits. A study limitation was that all variables were self-reported.

- Following a transfemoral amputation (TFA), numerous changes in movement patterns during gait can occur. Frontal plane hip and pelvis compensatory strategies are recognized among individuals with a TFA, some thought to aid in safe foot clearance during the swing phase of gait. The aim of this case study was to evaluate the effect of an active ankle dorsiflexion provided by a microprocessor-controlled prosthetic foot, as well as the effect of individualized training on these parameters. In this case study, a 42-year-old male underwent 3D gait analysis. Data were captured for two conditions; with a microprocessor-controlled prosthetic foot with active/inactive ankle dorsiflexion, during two sessions; before and after 6 weeks of individualized training. The main outcomes analyzed were frontal plane pelvis and hip kinematics. Prior to training, pelvic lift decreased slightly, coupled with an increase in hip abduction, during gait with the active ankle dorsiflexion of a prosthetic foot, compared to inactive dorsiflexion. After the training period, the pelvic lift was further decreased and an increase in hip adduction was concurrently seen. The results of this case study indicate a positive effect of the active dorsiflexion of the prosthetic foot but highlight the need for specific training after prescription of a microprocessor prosthetic foot.
