RESUMEN
OBJECTIVES: Balance disorders and falls are common in the elderly and have a multifactorial etiology. The purpose of the present cross-sectional study is to evaluate a possible association between vitamins D3 and B12 and impaired balance and falls. METHODS: Ninety patients, females and males, were evaluated, from December 2019 to December 2020 during their first ambulatory visit at the Prevention of Falls Clinic of the General University Hospital of Patras. Vitamins B12 and D3 levels were measured. The number of falls during the last 12 months was recorded and patients were assessed using Mini-Balance Evaluation Systems Test (Mini-BESTest), Fried Phenotype, Walking Speed, Hand Grip Strength, Short Physical Performance Battery. RESULTS: A multiple linear regression analysis showed that Mini-BESTest are statistically significantly predicted, F(10,79)=18.734, p<0.001, adj. R2=0.70 from Vit-B12 and FRIED Phenotype (pre-frail vs non-frail). Similarly, in the multiple binary logistic regression analysis, falls were statistically significantly predicted from FRIED Phenotype (pre-frail vs non-frail) χ2(5)=63.918, p<0.001, Nagelkerke R Squared=0.68. CONCLUSIONS: Higher levels of vitamins B12 but not of D3 are associated with better balance but not with less falls in a sample of community-dwelling older people.

BACKGROUND: Our aim was to identify predictors of mortality and limb loss in iatrogenic and civilian arterial trauma. METHODS: Cases were identified by searching prospectively maintained registries. Multivariable logistic regression was used to identify independent outcome predictors. RESULTS: During the study period, 285 patients with arterial trauma were managed with endovascular (n = 20) or open (n = 265) repair. Iatrogenic injuries increased in frequency during the course of the study, from 23.9% during the first decade to 35.9 and 55.7% during the second and third decade, respectively (p < 0.001). Endovascular management increased in frequency during the course of the study, from 0% during the first decade to 5.1 and 11.1% during the second and third decade, respectively (p = 0.005). Mortality was 9.8%, and limb loss (in cases with injury of the aorta or limb arteries, n = 259) was 6.2%. Independent predictors of mortality included increased age (odds ratio, 95% confidence interval [OR, 95% CI] 1.05 (1.02-1.07), p < 0.001), blunt trauma (OR [95% CI] 4.8 (1.9-12.2), p = 0.001) and the number of RBC units transfused intraoperatively (OR [95% CI] 1.25 (1.1-1.4), p = 0.001). Independent predictors of limb loss included the first half of the study period (OR [95% CI] 3.9 (1.1-14.1), p = 0.04), lower extremity arterial trauma (vs upper extremity, aortic, common or external iliac artery trauma, OR [95% CI] 8.3 (1.9-35.7), p = 0.004), bone fracture (OR [95% CI] 16.9 (4.7-62.5), p < 0.001) and the number of RBC units transfused intraoperatively (OR [95% CI] 1.16 (1.02-1.33), p = 0.024). CONCLUSION: Increasingly iatrogenic in cause and managed by endovascular methods, arterial trauma remains a problem associated with significant mortality and limb loss. Identification of unfavourable outcome predictors may help clinicians involved with arterial trauma to escalate the level of care.

OBJECTIVES: Test the reliability and validity of the modified Clinical test of Sensory Interaction in Balance (mCTSIB) of the Balance Platform Biodex Balance System (BBS) in a female community dwelling population. METHOD: 100 women over 65 years community dwellers mean age 71.8 (SD±6, ranging from 65 to 91) years, were examined using the posturography modified Clinical test of Sensory Interaction on Balance (mCTSIB) protocol of the Biodex Balance system SD and the Greek Mini-Best Test (miniBESTest-GR) to assess concurrent validity, with 24 undergoing a second measurement after one week to test the reliability of the method. RESULTS: The m-CTSIB-"Composite Score" test was significantly and positively correlated with the mini-BESTest-GR (r= -0.652, p<0.001) indicating good validity properties. The test-retest reliability was measured using the intra-class correlation coefficient (ICC) using a two-way mixed-effects absolute-agreement single-measurement model, among the two measurements of mCTSIB test (test-retest). No statistical difference was found between the two samples (N1=100, N2=24, t= -1.755, df=122, p=0.08). ICC estimates as 0.628 with 95% confident interval=0.31-0.82. CONCLUSION: The mCTSIB test from the BBS has a moderate validity and reliability to evaluate balance in elderly women living in the community and can be used as a screening tool.

Introduction A constant infusion of local anesthetics through pain pumps has been shown to cause chondrolysis. However, there is no general consensus regarding the safety of a single intra-articular injection of local anesthetics. In this experimental study, we examined the rat cartilage for possible histological effects after a single intra-articular administration of lidocaine or ropivacaine. Material and methods Thirty-two male Sprague-Dawley rats, weighing 250-300 grams, were divided into two groups of 16 each. We injected 0.1 ml of either lidocaine 2% (20 mg/ml) or ropivacaine 0.75% (7.5 mg/ml) into the left knee of the rats. The right knee in both groups was used as a control, and an equal amount of normal saline was injected. Each group was further divided into subgroups of four, which were euthanized after one, seven, 21, and 60 days after the initial injection. Knees were excised and prepared for histopathological analysis. A modified version of the Mankin score was used for cartilage damage evaluation. Results No difference regarding cartilage damage was detected after the examination under light microscopy between lidocaine, ropivacaine, and placebo in all specimens. Time elapsed since the initial injection did not affect the results at any time point. Conclusion A single intra-articular injection of local anesthetic did not induce any histological changes in the rat cartilage. Further research is needed to demonstrate the safety of humans.
RESUMEN
ABSTRACT: Frailty, a geriatric syndrome of growing importance in recent years, has been shown to be associated with increased risk of disability and adverse health and socioeconomic outcomes. Therefore, there is a need for new educational strategies for physical medicine and rehabilitation residents to promote greater geriatric competencies, with a focus on developing customized evaluation and management plans. With this article, the aim is offering a quick reference tool summarizing the latest evidence on the rehabilitative management of frailty. Indeed, a comprehensive geriatric evaluation is needed before developing an evidence-based and individually tailored rehabilitation program including physical activity, educative strategies, nutritional interventions, and proposals for social reintegration. In the future, appropriate educational training may allow a more careful management of these patients, with consequent improvements in quality of life and functionality.

PURPOSE: To detect radiographically occult cartilage lesions using CT arthrography (CTa) in patients with malleolar fractures treated with open reduction internal fixation and to correlate the lesions with the functional outcome score. MATERIALS AND METHODS: Twenty-one patients (13 men and 8 women, mean age 35 years, range 16-55) underwent ankle CTa after a mean postoperative period of 565 days (range 271-756). CTa images were analyzed by two radiologists. Articular surface post-traumatic collapse and subsequent cartilage defects or erosions were recorded in millimeters and in a binary mode (i.e., present if >50% of cartilage thickness) respectively. The functional outcome was assessed using the American Orthopedic Foot and Ankle Society (AOFAS) score by two orthopaedic surgeons. The statistical analysis correlated the AOFAS score with both imaging parameters and was performed with ANOVA using the MedCalc statistical package, version 11.3. RESULTS: Of the total of 12 articular surface steps recorded, 2/12 (16.67%) were anterolateral, 4/12 (33.33%) posterolateral, 5/12 (41.67%) anteromedial, and 1/12(8.33%) posteromedial. Of the total of 42 cartilage lesions, 7/42 (16.67%) were anterolateral, 14/42 (33.33%) posterolateral, 12/42 (28.57%) anteromedial, and 9/42 (21.43%) posteromedial. The mean AOFAS score was 8.67 (range 5.95-9.70). There was no statistically significant correlation between the AOFAS score and the post-traumatic internal derangement of the ankle joint (p = 0.524). CONCLUSION: CTa detects radiographically silent cartilage lesions in patients with fractures of the ankle joint. There is no correlation of the extent of lesions and the patient's AOFAS score.

INTRODUCTION: The Weil and triple Weil osteotomies are two widely used procedures in the surgical treatment of metatarsalgia. The aim of this comparative retrospective study was to evaluate the functional results and determine the complications of the two types of osteotomies in a series of patients who underwent surgery due to third rocker metatarsalgia. MATERIAL AND METHODS: In this paper, 71 patients were included between September 2015 and October 2020. The average age was 58 years old (age range: 28-72). Of all the patients, 27 suffered from metatarsalgia due to systemic (extra-regional) or regional diseases were excluded. The remaining 44 patients, after six months of unsuccessful conservative treatment, underwent surgery. Based on the preoperative planning to restore the peripheral parabolic curve of the metatarsals, when a shortening of less than or equal to 3 mm was required, a Weil osteotomy was performed. However, when a shortening of more than 3 mm was required, a triple Weil osteotomy was performed. Therefore, two groups of patients were formed, and a total of 90 osteotomies were performed. During the postoperative period, all the patients were clinically and radiographically assessed. The American Orthopedic Foot and Ankle Society (AOFAS) score was used for the assessment of the functional result, while the pain was assessed using the Visual Analogue Scale (VAS). RESULTS: The mean follow-up was 24 months. The average operative time for the Weil and the triple Weil osteotomies was 22.8 minutes and 31.5 minutes, respectively. In group A, preoperatively, the average AOFAS score was 31/100, and postoperatively, it was 89/100. In group B, the corresponding values were 30/100 and 93/100, respectively. In group A, the preoperative VAS score was 7.8/10, while the postoperative VAS score was 1.3/10. In group B, the corresponding values were 8.2/10 and 1.7/10, respectively. In group A, stiffness had a percentage equal to 60.9%, and a floating toe was noticed in 16 osteotomies. In group B, superficial infection represented the commonest complication, with an incidence of 25.6%. CONCLUSION: Both Weil and triple Weil osteotomies are effective procedures in the surgical treatment of patients who suffer from third-rocker metatarsalgia. In both cases, correct preoperative planning is of paramount importance for the outcome. However, in terms of the appearance of the floating toe, it seems that in cases where a ray's shortening of more than 3 mm is required, the triple osteotomy is superior to the Weil osteotomy.
RESUMEN
Background The aim of the present biomechanical study on cadavers was to determine both the center of rotation of the metatarsophalangeal joints and the position of the tendons of the interosseous muscles after the Weil and triple Weil osteotomies, and to compare these parameters in order to clarify the pathogenesis of dorsal stiffness and floating toe. Materials and methods Seven fresh-frozen cadaveric feet were utilized. After completing the preparation of both the plantar and the dorsal surface, we performed the dissection of the entire second, third and fourth rays, and each ray was fixed to a wooden wall mounted on a movable frame. The biomechanical analysis was based on an equilibrium system made of pulleys, threads, and variable weights. Geometrical analysis of both osteotomies and fluoroscopy was used to determine the initial and final metatarsophalangeal joint's center of rotation, as well as the change of interosseous muscles position. Results On comparing the results of the findings, we noticed that after Weil osteotomy, the metatarsophalangeal joint's center of rotation was proximally and plantarly displaced by 3.5 mm compared to the control group, and by 3.7 mm in comparison to the triple Weil osteotomy group. In the latter, the center of rotation was displaced by 0.817 mm compared to the control group. Furthermore, after the Weil osteotomy, the position of the interossei tendon was above the metatarsal longitudinal axis. Conclusion In cases where a metatarsal shortening of 5 mm or greater is desired, the Weil osteotomy causes a statistically significant plantar displacement of the metatarsophalangeal joint's center of rotation, compared to cases where triple Weil osteotomy is performed.
RESUMEN
Introduction Treatment of intra-articular fractures of the distal humerus is challenging due to their complexity, comminution, and associated complications. The evolution of surgical approaches and the design of elbow-specific implants over the last decades have failed to improve clinical and radiological outcomes. Studies are sparse regarding the long-term influence of surgical treatment of these types of fractures in the upper limb function. The purpose of the current study was to retrospectively review the long-term functional outcome and complications of all intraarticular (AO type B, C) distal humerus fractures treated surgically in a university hospital during the last 25 years. Material and methods The study included patients who were surgically treated for an intra-articular distal humerus fracture between March 1991 and May 2016. Our initial search, using ICD-10 codes, identified 63 patients in the specific time period. Twelve patients had died, nine declined to participate, eight had emigrated, nine could not be located and one patient was excluded as he suffered from quadriplegia unrelated to the initial injury. The remaining 25 patients (mean age at surgery 44.2±19.67) were included in a follow-up study protocol. Functional outcome was evaluated according to Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH). Pain was assessed using the Numerical Pain Rating Scale (NPRS) and subjects were asked to rate their satisfaction. Perioperative and late complications were recorded as well. Results The average follow-up was 158.16 ± 73.73 months. The average score was 89.4 ± 12.36 for MEPS, 42.68 ± 4.03 for OES, and 8.1 ± 15.38 for the QuickDASH. The patient satisfaction was rated 3.8 ± 1.08 on average. The mean flexion of the affected elbow was 137.6 ± 12.68 degrees while extension deficit was present in 14/25 patients, with a mean of 8.6 ± 8.96 degrees. We did not observe any mal- or non-unions. The re-operation rate was 32% primarily due to stiffness and irritation from the hardware. We noticed one spontaneously resolved ulnar nerve palsy, one combined radial, and ulnar nerve palsy after extensive arthrolysis that also resolved two cases of heterotopic ossification, one case of implant failure, and two cases of infection - one superficial, which was managed with antibiotics, and the other was deep managed with surgical drainage. Conclusions In our series, we found a satisfying range of motion, good functional outcome, and adequate ability to perform daily activities at a very long follow-up. Posttraumatic arthritis, whenever present, does not seriously affect functional performance. Level of evidence: IV.
RESUMEN
Background Hip fractures are an increasingly common injury among older people who usually experience significantly worse mobility, independence in function, health, quality of life, and high rates of institutionalization. Studies have shown that only 40-60% of participants recover their pre-fracture level of mobility and ability to perform instrumental activities of daily living, while for those who are independent in self-care prior to the fracture, 20-60% still require assistance for various tasks one or two years after the fracture. As the cumulative incidence of a second hip fracture has been estimated to reach 8.4%, prevention of the second hip fracture is a major concern of the health system and the society focused mainly on lifestyle modifications, osteoporotic treatment, and fall-prevention strategies. The aim of the present study was to compare morbidity/mortality, functional results, and type of recovery between the first and second hip fractures in elderly patients. Methods Patients with a contralateral hip fracture were prospectively recruited during a three-year period (2016-2019). Level of independence, gait aids, type of rehabilitation, American Society of Anesthesiologists (ASA) physical status, Harris Hip Score (HHS), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scale were evaluated at admission for the second fracture and at the last reexamination. Results Twenty-seven out of 33 patients, aged 87.93±6.6, underwent surgery for contralateral hip fracture and followed up for 42.52±16.46 months; the mean interval between the two fractures was 39.63 months. The HHS averaged 86.19±12.18 and 59.01±32.83 and the WOMAC 86.37±12.09 and 68.22±26.18 before and after the second fracture, respectively. The mortality rate was 37.03%, 14.8±12.93 months after the second operation, with a significant relationship between the mortality time and the interval between fractures (p=0.028). Twelve and 14 of the patients received geriatric nursing care after the first and second fracture, respectively, without significant improvement in their functional results compared to home care. Mobility of nursing care patients after the second fracture was significantly improved (p=0.019). Conclusions Mortality is higher in the second year after the second hip fracture and strongly correlated with the time interval between fractures. A higher possibility to return in previous mobility status occurs after geriatric nursing care.
RESUMEN
Introduction: Patients with neurodisabilities (NDS) are prone to alterations in body composition. Sarcopenic obesity (SO) is a condition characterized by increased adipose tissue accompanied by sarcopenia. The aim of this study was to investigate the prevalence of SO in patients with NDS, including stroke, spinal cord, and traumatic brain injuries. Methods: The study Sarcopenic Obesity in NeuroDisabled Subjects (acronym: SarcObeNDS) was a cross-sectional study of hospitalized patients (n = 82) and healthy controls (n = 32) with a mean age of 60.00 ± 14.22 years old. SO and sarcopenia were assessed through total body fat % (TBF %), fat mass index (fat mass to height2: FMI = FM/h2; kg/m2), and skeletal muscle index (appendicular skeletal muscle to height2: SMI = ASM/h2; kg/m2) via full-body dual-energy X-ray absorptiometry (DXA). This study was registered in the international database ClinicalTrials.gov with the unique identification number NCT03863379. Results: A statistically significant difference was found in SMI (7.18 ± 0.95 vs. 6.00 ± 1.13 kg/m2, p < 0.001) between controls and patients with NDS. No statistical significance was found for TBF (p = 0.783) and FMI (p = 0.143) between groups. The results remained the same after controlling the results for gender and BMI. A strong positive correlation was demonstrated between BMI and TBF for the total population (r = 0.616, p < 0.001), the control group (r = 0.616, p < 0.001), and patients with NDS (r = 0.728, p < 0.001). Conclusion: In summary, we observed significantly lower BMI and SMI scores in both genders compared to healthy controls. At the clinical level, a timely diagnosis and rapid treatment of sarcopenia and/or obesity in this population may prevent further metabolic repercussions accompanied by higher functional decline and lower quality of life.

BACKGROUND: In the management of malignancies of the extremities, limb salvage procedures have recently taken on greater significance. For those patients under intense adjuvant chemotherapy and with massive bone loss, free vascularized fibular grafting is currently advocated as a reliable reconstructive option, maybe because of the controversial results of bone transport in similar situations. However, when there is a vascular abnormality of either the recipient or donor extremity, microsurgical procedures are not feasible, further limiting potential reconstructive alternatives. METHODS: We present the case of a 13-year-old female patient with Ewing's sarcoma of the right tibia. Preoperative angiography showed that vascularity of the affected side depended totally on a single peroneal artery. The patient was treated initially with multiagent chemotherapy, followed by an excision of 23 cm. The defect was bridged by a gradual medial transportation of the ipsilateral fibula with the Ilizarov technique and strengthened by nonvascularized transfer of the contralateral fibula. RESULTS: Total external fixation time was 162 days. After the removal of the Ilizarov frame a walking cast was applied for another month. At 5 years postoperatively there was no recurrence of the malignancy. The patient had full weight-bearing ability on the affected limb, with preservation of the ankle and knee joints motion and without any limb length discrepancy or axial deformity. The functional outcome that was visible was graded excellent. CONCLUSIONS: Transverse distraction osteogenesis of the ipsilateral fibula performed well under chemotherapy, showing unproblematic callus formation. Supplemented with nonvascularized transfer of the contralateral fibula, provided a reconstructive option with biological affinity, sufficient biomechanical strength and durability, and with a decreased complication rate. This case report presents a viable option, especially in cases in which vascular abnormalities of either the donor or the recipient limb, combined with multiagent chemotherapy, restrict potential reconstructive alternatives. It also highlights why vascularized bone graft should not be regarded as a panacea for all situations in which a fibular graft is required. LEVEL OF EVIDENCE: Level IV, case report.

BACKGROUND Chronic posterior knee dislocation after total knee arthroplasty (TKA) is a rare but serious complication, especially when it coexists with septic implant loosening, flexion contracture, and extensive comorbidities. Although the severity is comparable to that in the native knee dislocation, there are few reports in the literature. When TKA dislocation is complicated with infection, bone defect, and patient's comorbidity, treatment becomes even more difficult. For these complex complications, in order to provide stable and mobile knees, constrained total knee prostheses are used. CASE REPORT We present the case of a 63-year-old, non-ambulatory man, with mental retardation and multiple comorbidities, who had a 9-year history of neglected posterior TKA dislocation, which later became complicated with septic loosening and productive fistula for 4 years. The patient required use of a wheel-chair for several years, was obese with a body mass index (BMI) of 34.3, and the affected knee was in a prolonged flexion contracture at 90°. The posterior TKA dislocation was later infected by Staphylococcus hominis and Staphylococcus epidermidis. He was successfully treated with two-stage revision surgery and managed to become ambulatory after 6 years of requiring use of a wheel-chair. CONCLUSIONS Neglected posterior dislocation of TKA is a rare and potentially limp-causing complication, especially when accompanied with chronic infection, implant loosening, severe bone loss, flexion contracture, and extensive comorbidities. A multidisciplinary approach with careful preoperative planning, exceptional surgical technique, and prolonged supervised physiotherapy are the keystones for a successful outcome.

This is a prospective randomized study comparing cefuroxime to 2 antistaphylococal agents (fusidic acid and vancomycin), for prophylaxis in total hip arthroplasty (THA) and total knee arthroplasty (TKA) in an institute, where methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus epidermidis (MRSE) prevalence exceeds 25% of orthopedic infections. There were 3 patient groups. Group A included the patients who received cefuroxime, group B those who received fusidic acid, and group C those who received vancomycin. Patients were evaluated for the presence of superficial and/or deep infection at the surgical site. Statistical analysis did not reveal any substantial difference between the 3 groups. We do not recommend the use of specific antistaphylococcal agents for prophylactic use in primary THA and TKA, even in institution where MRSA and MRSE exceed 25% of orthopedic infections.

CASE: We report the case of an 82-year-old woman with diabetes, arteriosclerosis, chronic heart failure, and hypertension treated with an anatomical locking plate and multiple cables for a spiral-wedged periprosthetic fracture of the distal femur which was complicated by direct occlusion of the femoral artery and crush of the sciatic nerve, resulting in leg necrosis and, ultimately, through-knee disarticulation despite early recognition and arterial repair. CONCLUSIONS: Neurovascular injury is a potential complication of cerclage cables placement around the femoral shaft during complex fracture fixation. Devastating complications cannot always be corrected despite early vascular intervention.

Purpose: To translate and validate into the Greek language and setting the Sarcopenia Quality of Life (SarQoL®) questionnaire.Methods: A convenience sample of 176 Greek elderly people (136 females, 40 males; aged 71.19 ± 7.95 years) was recruited, 50 of which (36 females, 14 males) were diagnosed sarcopenic. Questionnaire was back-translated and culturally adapted into Greek according to international guidelines. To validate the Greek SarQoL®, we assessed its validity (discriminative power, construct validity), reliability (internal consistency, test-retest reliability) and floor/ceiling effects. Participants were divided into sarcopenic and non-sarcopenic. Sarcopenic subjects apart from the Greek SarQoL (SarQoLGR) filled out the Greek versions of two generic questionnaires; Short Form-36 and EuroQoL 5-dimension.Results: The Greek SarQoL questionnaire was translated without major difficulties. SarQoLGR mean scores were 52.12 ± 11.04 (range: 24.74-71.81) for sarcopenic subjects and 68.23 ± 14.1 (range: 24.83-94.81) for non-sarcopenic ones. Results indicated good discriminative power across sarcopenic and non-sarcopenic subjects (p = 0.01), high internal consistency (Cronbach's alpha of 0.96) and excellent test-retest reliability (ICC = 0.96, 95% CI = 0.95-0.97). Neither a floor nor a ceiling effect was observed.Conclusions: The Greek SarQoL was found to be a reliable and valid measure of quality of life for sarcopenic patients. It is therefore, available for use in future clinical research and practice.Implications for rehabilitationThe Greek version of the SarQoL® questionnaire is a valid and reliable outcome measure for assessing patients with sarcopenia.The Greek SarQoL is recommended to be use in clinical settings and research.The Greek SarQoL® questionnaire is available online www.sarqol.org.

INTRODUCTION: Foot deformities and amputations are parameters that have been studied as risk factors for diabetic foot ulceration (DFU). However, inclusion of "foot deformities" and "amputations" in a single, broad variable and with reference to the severity of these deformities, may better characterize subjects who are prone to develop DFU. METHODS: The objective of the study was the examination of amputative and non-amputative foot deformities severity as risk factor for DFU in relation with the other established risk factors. A cross-sectional and case-control study was conducted from October 2005 to November 2016. One hundred and thirty-four subjects with type 1 and 2 diabetes, with and without active foot ulcers, participated. A structured quantitative interview guide was used. Univariate logistic regression analysis for the literature's established risk factors was performed, as well as for two versions of the "amputative and non-amputative foot deformities severity" variable. Subsequently, multivariate logistic regression analysis (MLRA) for three models and receiver operating characteristic (ROC) curve analysis were carried out. RESULTS: From the MLRA, only PAD (peripheral arterial disease) was significant (OR 3.56, 95% CI 1.17-10.82, P=0.025 and OR 3.33, 95% CI 1.02-10.08, P=0.033). Concerning the ROC curve analysis of the models, the one with the three categories amputative and non-amputative foot deformities severity variable, had the greatest area under the ROC curve (0.763, P<0.001). CONCLUSION: A united variable for lower extremity amputations and other foot deformities with reference to their severity, could be more helpful to the clinicians in identifying patients with diabetes at risk for foot ulceration.

The effect of an electric field within specific intensity limits on the activity of human cells has been previously investigated. However, there are a considerable number of factors that influence the in vitro development of cell populations. In biocompatibility studies, the nature of the substrate and its topography are decisive in osteoblasts bone cells development. Further on, electrical field stimulation may activate biochemical paths that contribute to a faster, more effective self-adjustment and proliferation of specific cell types on various nanosubstrates. Within the present research, an electrical stimulation device has been manufactured and optimum values of parameters that led to enhanced osteoblasts activity, with respect to the alkaline phosphatase and total protein levels, have been found. Homogeneous electric field distribution induced by a highly organized titanium dioxide nanotubes substrate had an optimum effect on cell response. Specific substrate topography in combination with appropriate electrical stimulation enhanced osteoblasts bone cells capacity to self-adjust the levels of their specific biomarkers. The findings are of importance in the future design and development of new advanced orthopaedic materials for hard tissue replacement.

Open transtrapezium injuries of the thumb are not common and sufficiently described injuries. We have clinically and radiologically evaluated six patients with transtrapezium injury of the thumb. The average follow-up time was 65 months. All injuries occurred in young people, who had high-energy trauma to their thumb. Fracture of the trapezium with exposure of the first carpometacarpal joint was a constant along with soft tissue damage. The latter included thumb tendons, digital nerves and arteries, motor branch of the median nerve, palmar or dorsal branch of the radial artery, and thenar musculature. All trapezium fractures were fixed with mini 1.5 mm screws. All the other injured structures were repaired by microsurgical techniques. Physiotherapy protocols with emphasis to electrostimulation were used within 2 weeks postoperatively. Clinical assessment included objective and subjective criteria, which revealed moderate loss of motion because of musculature loss either by direct trauma or by denervation. No correlation was found between types of trapezium fracture and disability. Internal osteosynthesis with 1.5 mini cortical screws provided excellent stability. Despite the severity of the initial trauma the results were surprisingly good.

BACKGROUND: Spinal cord injury without radiographic abnormalities (SCIWORA) is thought to represent mostly a pediatric entity and its incidence in adults is rather underreported. Some authors have also proposed the term spinal cord injury without radiologic evidence of trauma, as more precisely describing the condition of adult SCIWORA in the setting of cervical spondylosis. The purpose of the present study was to evaluate adult patients with cervical spine injuries and radiological-clinical examination discrepancy, and to discuss their characteristics and current management. METHODS: During a 16-year period, 166 patients with a cervical spine injury were admitted in our institution (Level I trauma center). Upper cervical spine injuries (occiput to C2, 54 patients) were treated mainly by a Halo vest, whereas lower cervical spine injuries (C3-T1, 112 patients) were treated surgically either with an anterior, or posterior procedure, or both. RESULTS: Seven of these 166 patients (4.2%) had a radiologic-clinical mismatch, i.e., they presented with frank spinal cord injury with no signs of trauma, and were included in the study. Magnetic resonance imaging was available for 6 of 7 patients, showing intramedullary signal changes in 5 of 6 patients with varying degrees of compression from the disc and/or the ligamentum flavum, whereas the remaining patient had only traumatic herniation of the intervertebral disc and ligamentum flavum bulging. Follow-up period was 6.4 years on average (1-10 years). CONCLUSION: This retrospective chart review provides information on adult patients with cervical spinal cord injuries whose radiographs and computed tomography studies were normal. It furthers reinforces the pathologic background of SCIWORA in an adult population, when evaluated by magnetic resonance imaging. Particularly for patients with cervical spondylosis, special attention should be paid with regard to vascular compromise by predisposing factors such as smoking or vascular disease, since they probably contribute in the development of SCIWORA.
