The aim of this research (Motor control Home ergonomics Elderlies' Prevention of falls; McHeELP study) was to develop a novel intervention combining motor control home-based exercises and a home ergonomic safety-improvement strategy in order to reduce falls in frail ambulatory older adults. A randomized controlled trial of a novel intervention is proposed including motor control exercises and home ergonomic assessment and modification in older adults who have at least one fall experience. Participants are randomized to control or intervention group in a 1:1 ratio. Participants will be assessed three times: at baseline, at 3rd month (end of intervention period) and again at 6th month (follow-up measurement). The primary outcome is of the effect on functional mobility using the Timed Up and Go test. Secondary outcomes include assessments of functionality, fear of falling and quality of life. This will be the first study to develop an exercise intervention approach that combines home-based motor control exercise intervention with home assessment and modification. This study is expected to explore a low-cost, easy-to-popularize, and effective exercise intervention approach for improving functional mobility and prevent falls among older adults.

Background: Chronic obstructive pulmonary disease (COPD) is associated with a progressive loss of muscle mass and function and a systemic inflammatory process that can cause sarcopenia. Objective: The objective of this study is to estimate the prevalence rate of sarcopenia in COPD patients and to determine the factors associated with sarcopenic patients living in Western Greece. Methods: European Working Group on Sarcopenia in Older People criteria were applied to 69 outpatients with stable COPD. Body composition, exercise capacity, functional performance, physical activity, and health status were also assessed. COPD disease severity (COPD stage) was evaluated with the Global Initiative for chronic obstructive lung disease. The study protocol was approved by the Ethical Committee of the Technological Educational Institute of Western Greece. Results: The sample comprised 69 patients (59 women and 10 men), with a mean age of 71.33 ± 7.48 years. The prevalence of sarcopenia was 24.6% (n = 17). A high percentage (82.6%; n = 57) of the 69 Greek participants did not perform any regular exercise. The findings of this study demonstrated that sarcopenia was positively associated with COPD, age, body mass index, skeletal muscle mass, hand grip strength, and 4 m test. Conclusions: In conclusion, there is a 24.6% prevalence of sarcopenia in patients with COPD. Further research with larger samples would be indicated to clarify the precise association of specific characteristics of patients with sarcopenia and COPD.

OBJECTIVE: The aim of this systematic review was to evaluate the available published evidence on the intra- and inter-rater reliabilities of assessment methods used for identifying and measuring scapular dyskinesis (SD) in asymptomatic subjects. METHODS: A systematic electronic literature search was performed in PubMed, Physiotherapy Evidence Database, Scopus, and the Cochrane Library, and studies on the intra- and inter-rater reliabilities of physical examination tests used for identifying SD in asymptomatic people were identified. Methodological quality of the studies meeting the inclusion criteria was assessed using the Quality Appraisal of Reliability Studies (QAREL) checklist by two reviewers. The overall level of evidence of this systematic review was determined by the Modified Cochrane Back Pain Criteria based on previous research which was modified for reliability studies of the shoulder complex. RESULTS: The literature search generated 388 results, and only 14 articles met the inclusion criteria. In these studies, reliabilities of two qualitative and five quantitative methods for the assessment of SD were analyzed. The QAREL checklist revealed that 12 studies had moderate risk of bias and 2 had high risk of bias. Additionally, none of the studies were of high quality. On the basis of the Modified Cochrane Back Pain Criteria, the overall level of evidence was moderate. Most of the studies including quantitative measurement methods found good to excellent inter- and intra-rater reliability values. Most of the studies including qualitative methods found low-to-moderate intra- and inter-rater reliability values. CONCLUSION: Considering the available published evidence, there is lack of high-quality studies evaluating the inter- and intra-rater reliabilities of qualitative or quantitative methods used for the assessment of SD. There are no qualitative methods with high reliability that are fit for clinical applications. Some quantitative methods with higher reliability are present, but clinicians should be aware of the methodological flaws that studies evaluating these methods suffer from. LEVEL OF EVIDENCE: Level II, Diagnostic study

Patient: Male, 62-year-old Final Diagnosis: Arthroplasty • knee • posterior dislocation • prolonged flection contracture • septic loosening Symptoms: Knee joint pain Medication: — Clinical Procedure: — Specialty: Orthopedics and Traumatology Objective: Patient complains/malpractice 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.

Objectives Physical exercise is a key intervention for improving functional ability and preventing falls in older people. However, the implemented interventions targeted balance, gait, and muscle strength, while little is known regarding motor control exercises in this population. Therefore, this study aimed to investigate the effects of a 12-week home-based motor control exercise program combined with an ergonomic home modification (the McHeELP program). Patients and methods Fifty-two older people (aged ≥65 years), who had experienced at least one fall incident in the past 12 months, were randomly assigned into two groups; the McHeELP group (McHeELP-G) (n=26) that received the McHeELP program and the control group (CG) (n=26). Physical performance measures (PPMs) and patient-reported outcomes (PROs) were used to evaluate participants. At baseline, 3rd month (post-intervention), and again at 6th month (follow up), balance control was assessed using the Tandem stance test (Tandem) and the Functional Reach Test (FRT). Functionality was assessed by the 4 meters walking test (4MWT), Timed Up and Go (TUG) test, 30 seconds-Sit to stand test and the Greek version of Lower Extremity Functional Scale (LEFS-Greek). The Greek version of the Falls Self-efficacy International scale (FES-I_GREEK) was used for the evaluation of "fear-of-falling" (FOF). The home falls and accidents screening tool (HOMEFAST) is used to identify home hazards. Two-way mixed ANOVA model, independent samples t-test, One-factor Repeated Measures ANOVA model and ANCOVA model were used for the statistical analysis of the data. Results Homogeneity was found between McHeELP-G and CG regarding the demographic and clinical characteristics, and no statistically significant difference was found at baseline measurements of PROs and PPMs, except HOMEFAST (p=0.031). Post-intervention (3rd month), the comparison of the absolute values between groups revealed that the McHeELP-G achieved statistically significant better balance control (longer Tandem stance test and higher values of FRT), better functionality [faster gait speed (4MWT), shorter TUG performance time, and a higher number of repetitions at 30 seconds-Sit to stand] (all p-values

Background There is accumulating evidence for the advantages of rehabilitation involving sensori-motor training (SMT) following total knee replacement (TKR). However, the best way in which to deliver SMT remains elusive because of potential interference effects amongst concurrent exercise stimuli for optimal neuromuscular and morphological adaptations. The aim of this study was to use additional outcomes (i.e. muscle strength, activation and size) from a published parent study to compare the effects of early-initiated home-based rehabilitative SMT with functional exercise training (usual care) in patients undergoing TKR. Methods A controlled clinical trial was conducted at the Orthopedic University Hospital of Rion, Greece involving allocation concealment to patients. Fifty-two patients electing to undergo TKR were randomised to either early-initiated SMT [experimental] or functional exercise training [control] in a home-based environment. Groups were prescribed equivalent duration of exercise during 12-weeks, 3–5 sessions of ~ 40 min per week of home-based programmes. Muscle strength and activation (peak force [PF]; peak amplitude [Peak Amp.] and root mean square of integrated electromyography [RMS iEMG]), muscular size (including rectus femoris muscle cross-sectional area [CSARF]), and knee ROM were assessed on three separate occasions (pre-surgery [0 weeks]; 8 weeks post-surgery; 14 weeks post-surgery). Results Patients undertaking SMT rehabilitation showed significantly greater improvements over the 14 weeks compared to control in outcomes including quadriceps PF (25.1 ± 18.5 N vs 12.4 ± 20.8 N); iPeak Amp. (188 ± 109.5% vs 25 ± 105.8%); CSARF (252.0 ± 101.0 mm2 vs 156.7 ± 76.2 mm2), respectively (p

Objectives Falls are a serious problem that can reduce living autonomy and health-related quality of life of older adults. A decrease in the muscular strength of the lower limbs and the deterioration of balance or motor performance deficits may lead to falls. "Motor Control Home Ergonomics Elderlies' Prevention of Falls" (McHeELP) is a novel motor control exercise program combined with ergonomic arrangements of the home environment. This pilot trial is conducted in order to examine the feasibility and acceptability of the McHeELP program, the selection of the most appropriate outcome measures, and the exact sample size calculation that should be used for the randomized controlled trial (RCT) with Clinical Trial Identifier: ISRCTN15936467. Patients and methods Twenty older adults (aged ≥65 years) who had experienced at least one fall-incident in the past 12 months have participated in the trial; they were randomized in a 1:1 ratio to the McHeELP group (McHeELP-G) and the Control group (CG). The McHeELP-G received a personalized therapeutic motor control and learning exercise program performed three times per week for 12 weeks. Regarding McHeELP - home modification, a booklet that contained basic advice and tips on the modification for their inside and outside home environment was provided to the participants. Objective and self-reported outcome measures, collected at baseline and post-intervention (end of the third month), included functional, fear of falling, and quality of life measurements. Results The McHeELP intervention was very feasible and acceptable to the participants, and the adherence was excellent (100%). The majority of outcome measures seemed appropriate and significant differences were also revealed between the two groups. Specifically, post-intervention statistically significant improvement was found in the 4 meters walking test, Timed Up and Go test, Sit to Stand test, Tandem Stance test, Functional Reach test, Foot tapping test, EuroQoL-5D-5L - visual analog scale (VAS), Lower Extremity Functional Scale, Falls Self-Efficacy International Scale, and Home Falls and Accidents Screening Tool (HOMEFAST) questionnaire of McHeELP-G (all p-values ≤0.002). No statistically significant difference was observed in the mobility, self-care, usual activities, pain/discomfort subscales of Euro QoL-5D-5L (all p-values >0.05), except the anxiety/depression subscale of McHeELP-G (p=0.008). Moreover, no statistically significant improvement was found regarding McHeELP participants' knee flexion/extension restriction and ankle dorsiflexion/plantar-flexion restrictions. Regarding CG, no statistically significant difference was found (p>0.05), except the Tandem Stance test (p=0.003) and HOMEFAST (p

Objectives: The objective of this study was to assess the prevalence rate of probable sarcopenia and to determine the factors associated with it in older people living in Western Greece. Methods: Probable sarcopenia was estimated based on cut-off values for handgrip strength (HGS) as recommended by EWGSOP2. Information about socio-demographic, chronic diseases, fear of falls and lifestyle of the participants were also collected. HGS was assessed using a SAEHAN dynamometer. Calf circumference was assessed with inelastic tape. A logistic regression analysis was performed in order to determine associated risk factors. Results: The sample comprised 402 participants (292 women;110 men), with a mean age of 71.51±7.63 years. Overall, 25.4% of the elderly participants were diagnosed with probable sarcopenia (men:36.4%; women:21.2%). The findings of this study demonstrated that probable sarcopenia was positively associated with age (OR=0.14, 95% CI=0.008 to 0.200), gender (OR=-0.6, 95% CI=-0.700 to -0.530), Body mass Index (OR=0.01, 95% CI=-0.030 to -0.005), Skeletal muscle mass index (OR=0.05, 95% CI=0.030 to 0.080), calf circumference (OR=0.02, 95% CI=0.007 to 0.040), and comorbidities (OR=0.04, 95% CI=0.030 to 0.080). Conclusion: There was a 25.4% prevalence of probable sarcopenia in Greek elderly. The results highlight the importance of the detection of HGS and probable sarcopenia in older people in order to develop effective strategies of prevention and intervention of sarcopenia.

Purpose To compare anterior cruciate ligament (ACL) autograft reconstruction using fixed-looped suspensory versus expandable femoral fixation through the anteromedial portal. Methods After we performed prospective power analysis and obtained institutional review board, 70 patients with ACL rupture were block randomized to the expandable or suspensory femoral fixation group (35 in each group). All patients received autologous hamstring autograft through the anteromedial portal and fixed with a sheath-screw system in the tibia. The primary outcome measures were anteroposterior knee stability at 2 years’ follow-up measured using the KT-1000 arthrometer and the degree of femoral and tibial tunnels’ widening measured by the use of computed tomography imaging performed immediately postoperative and 12 months postsurgery. Secondary outcome measures included pain score on a visual analog scale, the subjective International Knee Documentation Committee 2000 assessment form, the Lysholm score, and the Tegner activity scale at 3, 6, 12, and 24 months. Results Twenty-four patients were excluded from further analysis, leaving a total of 48 patients (24 in each group) for the final evaluation. The anteroposterior knee stability (KT-1000) showed no difference between groups at 24 months’ follow-up (P = .31). The percentile widening (%) of femoral and tibial tunnel at 1-year follow-up showed no difference also, except for greater values at the tibial coronal point T2 (P = .065) and tibial sagittal point T1 (P = .033) in the group of cortical buttons. Secondary clinical outcomes showed no statistical differences between groups at 3, 6, 12, and 24 months’ postoperatively. Numerical pain scale (visual analog scale) was similar in both groups except for postoperative day 7, where the AperFix group showed better results (P = .014). There were no major intraoperative and late postoperative complications in any of the groups. Conclusions Our results showed no significant differences in knee anteroposterior stability, tunnel enlargement or other clinical outcomes comparing expandable versus cortical button fixation in anteromedial hamstrings ACL reconstruction. Level of Evidence Level II, randomized controlled trial.

Our aim was to identify predictors of mortality and limb loss in iatrogenic and civilian arterial trauma. Cases were identified by searching prospectively maintained registries. Multivariable logistic regression was used to identify independent outcome predictors. 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

We report the case of a 40-year-old man presenting at the emergency department with ankle and feet edema due to acute sarcoidosis (Lofgren syndrome). The diagnosis was suggested based on an ultrasound examination showing bilateral asymmetrical tenosynovitis of the flexor tendons with hypervascular subcutaneous cellulitis without any significant ankle and foot joint effusion or synovitis. This case report highlights the crucial role of ultrasound imaging as the first-line diagnostic tool in the investigation of a non-specific clinical condition, when performed by a knowledgeable sonographer with attention to detail. Radiologists performing ultrasound should be aware of the presenting ultrasound pattern of acute soft tissue sarcoidosis, and should include this entity in the differential diagnosis of patients with distal lower extremity swelling, tenosynovitis and hypervascular subcutaneous cellulitis, in order to narrow down the differential diagnosis and facilitate the clinical workup of the patient.

The Knee Injury Osteoarthritis Outcome Score (KOOS)-Child questionnaire is one of the frequently child-friendly measures used in pediatric studies. The aim of this study was to transculturally adapt the Greek version of KOOS-Child and evaluate its clinimetric properties in children with knee disorders. Children visiting the Outpatients Orthopaedic Clinic of a Greek Paediatric General Hospital were considered eligible if they were aged 8–14 years, had a knee soft tissue injury and associated physical limitations. The transcultural adaptation was based on a multistage backward translation approach. Participants completed the KOOS-Child at their first visit to the orthopedic specialist (baseline), 2 weeks and 3 months after baseline. Content validity of the KOOS-Child was evaluated using general QoL measures (KIDSCREEN and Kid-KINDL) and construct validity was explored by correlating relevant items. Responsiveness was evaluated according to the children’s response on the given orthopeadic treatment. Sample consisted of 59 children (30 males), aged: 11 ± 1.8 years. The KOOS-Child showed high internal consistency (Cronbach’s a: 0.80–0.96). Adequate convergent validity with > 75% relevant a priori hypotheses was confirmed. Construct validity was moderate to strong (Pearson’s r correlations between related KOOS and Kid-KINDL subdimensions: 0.54–0.62). KOOS and KIDSCREEN subdimensions correlations were fair (Pearson’s r correlations: 0.32–0.65). KOOS-Child’s diagnostic accuracy was high. Factor analysis extracted height factors accounting for 76.15% of the total variance, confirmed by the scree plot. Responsiveness was moderate to high with Cohen’s d from 0.6 to 1.4. The Greek version of the KOOS-Child demonstrated excellent internal consistency, good construct validity, diagnostic accuracy and interpretability as well as good responsiveness. The measure could be used across Greek children with orthopaedic knee problems. Generalisability of findings is limited due to the relatively limited cohort. II.

AIM To present the long-term results of complex knee injuries, treated early using the Ligament Augmentation and Reconstruction System (LARS) artificial ligament to reconstruct posterior cruciate ligament (PCL). METHODS From September 1997 to June 2010, thirty-eight complex knee injuries were treated, where early arthroscopic PCL reconstructions were undergone, using the LARS (Surgical Implants and Devices, Arc-sur-Tille, France) artificial ligament. Exclusion criteria were: Late (> 4 wk) reconstruction, open technique, isolated PCL reconstruction, knee degenerative disease, combined fracture or vascular injury and use of allograft or autograft for PCL reconstruction. Clinical and functional outcomes were assessed with IKDC Subjective Knee Form, KOS-ADLS questionnaire, Lysholm scale and SF-12 Health Survey. Posterior displacement (PD) was measured with the Telos Stress Device. RESULTS Seven patients were excluded; two because of co-existing knee osteoarthritis and the remaining five because of failure to attend the final follow-up. The sample consisted of 31 patients with mean age at the time of reconstruction 33.2 ± 12.5 years (range 17-61). The postoperative follow-up was on average 9.27 ± 4.27 years (range 5-18). The mean average IKDC and KOS scores were 79.32 ± 17.1 and 88.1 ± 12.47% respectively. Average PD was 3.61 ± 2.15 mm compared to 0.91 ± 1.17 mm in the uninjured knees (one with grade 1 + and two with grade 2 +). Dial test was found positive in one patient, whereas the quadriceps active drawer test was positive in three patients. None was tested positive on the reverse-pivot shift test. The range of motion (ROM) was normal in thirty knees, in comparison with the contralateral one. There was no extension deficit. Osteoarthritic changes were found in three knees (9.6%). CONCLUSION Early treatment of complex knee injuries, using LARS artificial ligament for PCL reconstruction sufficiently reduces posterior tibia displacement and provides satisfactory long-term functional outcomes.

Objective: To assess the effects of early self-managed focal sensorimotor training compared to functional exercise training after total knee replacement on functional mobility and sensorimotor function. Design: A single-blind controlled clinical trial. Setting: University Hospital of Rion, Greece. Subjects: A total of 52 participants following total knee replacement. Outcome measures: The primary outcome was the Timed Up and Go Test and the secondary outcomes were balance, joint position error, the Knee Outcome Survey Activities of Daily Living Scale, and pain. Patients were assessed on three separate occasions (presurgery, 8 weeks post surgery, and 14 weeks post surgery). Intervention: Participants were randomized to either focal sensorimotor exercise training (experimental group) or functional exercise training (control group). Both groups received a 12-week home-based programme prescribed for 3–5 sessions/week (35–45 minutes). Results: Consistently greater improvements ( F2,98 = 4.3 to 24.8; P Conclusions: Overall, the magnitude of improvements in functional mobility and sensorimotor function endorses using focal sensorimotor training as an effective mode of rehabilitation following knee replacement.

All rights reserved. BACKGROUND: Although low back pain (LBP) is a debilitating problem internationally, there is not a lot of research on its impact on physical, psychosocial and lifestyle factors. Especially in mediterranean countries, such as Greece, it is not sufficiently explored whether physical (pain location, activity limitation etc.), sociodemographic (education, smoking etc.) or lifestyle factors (i.e. quality of life or anxiety) are influenced by LBP. OBJECTIVE: To estimate LBP prevalence in the Greek general population and explore its association with particular sociodemographic, physical and lifestyle factors. METHOD: A sample of 3125 people of the Greek adult population was randomly selected by stratified sampling encompassing rural and urban representation within the Greek mainland. An extended survey form was developed entailing three sections; personal (sociodemographic) information, questions on symptomatology and physical factors (i.e. pain characteristics, recurrence, physical disability etc.) and 3 self-administered questionnaires (including mostly lifestyle factors); Hospital Anxiety and Depression (HAD) scale for anxiety and depression, SF-12 for quality of life (QoL) and Roland-Morris for disability. RESULTS: A total of 471 (15%) people reported LBP (210 males, mean age: 47.04 ' 15.03). Amongst them 60% reported sciatica, 76% suffered recurrent LBP and 70% received specialist care. Low disability levels, moderate to high pain intensity, gender differences and good self-reported QoL and psychosocial status were reported. Sociodemographic characteristics (income, smoking, marital status etc.) were not associated with LBP physical factors, apart from age which correlated with physical disability and wellness (r being 0.446 and 0.405, respectively, p < 0.001). Physical factors (particularly pain intensity and location) correlated with lifestyle factors (QoL) and disability (r ranging between 0.396 and 0.543, p < 0.001). Mental wellness, anxiety and depression (as lifestyle factors) were not associated with sociodemographic or physical factors. CONCLUSIONS: Physical parameters were amongst the most prevalent characteristics of the Greek sample, thus offering a direction towards a more targeted treatment and rehabilitation planning. Unlike previous literature, most sociodemographic characteristics were not correlated with any LBP physical or lifestyle factors, thus possibly indicating a different socioeconomic background and aetiology domain to that of the usual non-specific LBP spectrum.

To compare accuracy, patient discomfort, and clinical outcome of ultrasound-guided versus palpation-guided corticosteroid injections to the bicipital groove in patients with long head of biceps (LHB) tendinosis. Forty-four patients with primary LHB tendinosis were randomized into two groups (group A, n = 22; group B, n = 22). All patients underwent treatment with a single corticosteroid injection to the bicipital groove. Injections in group A were performed under ultrasound-guidance, while in group B using a palpation-guided technique. The duration of each procedure was recorded. To assess accuracy, ultrasound examination was performed in both groups after injection. Patient discomfort was evaluated with visual analogue scale (VAS) for pain. The clinical outcome was assessed comparing the VAS, the Single Assessment Numeric Evaluation (SANE) score and the QuickDASH score before treatment and after 4 weeks and 6 months. The mean duration of the procedure was 64 ± 6.87 s in group A and 81.91 ± 8.42 s in group B (p

Background Keele STarT Back Screening Tool (SBST) is a popular 9-item prognostic recovery questionnaire for low back pain (LBP) with validation studies in several cultural settings, but not Greek. Objectives The cross-cultural adaptation and validation of the SBST into Greek among LBP and LBP-associated leg pain patients. Methods A five-stage forward-backward translation procedure developed the Greek SBST. LBP and sciatica patients completed SBST, Roland-Morris Disability Questionnaire (RMDQ), Hospital Anxiety and Depression Scale (HADS), Short-form Health Survey (SF-12), Sciatica Bothersomeness Index (SBI), numeric pain rating scale (NPRS) and body chart pain location sites. Measurement properties (internal consistency, content, construct and discriminatory validity) were explored. Test-retest reliability was explored by re-administering SBST after 7–10 days across patients whose symptoms remained unchanged. Results 124 LBP patients (75 females, 49.1 ± 14.2 years-old) 43.5% of whom had sciatica completed Greek SBST. No floor/ceiling effects were detected. Mean score distributions were statistically different across SBST groups. Moderate to strong correlations were found for SBST (total and psychosocial scores) with RMDQ, SBI, HADS and SF-12 (Spearman's ρ = 0.42–0.60). Most associations between individual SBST items and reference standards were moderately correlated (ρ = 0.32–0.49). Greek SBST yielded acceptable discriminant validity with RMDQ (AUC of 0.80). Items 1, 3, 4, and 9 yielded acceptable discrimination against reference standards. Test-retest reliability was satisfactory for total score (ICC2,2 = 0.93) and individual items (kappa = 0.59–0.88). Cronbach's α was 0.70 (total score) and 0.76 (psychosocial subscale). Conclusions The Greek SBST was comprehensible, valid and reliable and may thus, be used across Greek cross-cultural rehabilitation research and practice.

Purpose Despite the high incidence of falls in patients with OA, few studies have explored whether falls risk is affected after patients undergo total knee arthroplasty (TKA). Therefore, the aim of this systematic review was to identify the extent of the effects of TKA on balance and incidence of falls by critically reviewing the available literature. Methods A systematic review of published literature sources was conducted up to March 2014. All studies assessing balance and incidence of falls after TKA (without physiotherapeutic intervention) were included. The methodological quality of each study was reviewed using the Critical Appraisal Skill Programme tool. Results Thirteen studies were included, comprising of ten cohort studies (Level II) and three studies with Level of evidence III. Conclusions Findings provide evidence that TKA improves significantly single-limb standing balance (~60%) and dynamic balance up to 1-year following surgery (Level of evidence II). Moreover, TKA influences positively fear of falling and incidence of falls by switching 54.2 % of pre-operative fallers to post-operative non-fallers (Level of evidence II–III). It is highlighted that knee extension strength, proprioception and symmetrization of postural strategies have not fully recovered post-TKA and influence balance performance. Clinically, these persistent deficits need to be mitigated by physiotherapy even before TKA takes place.

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,...

Physical exercise is effective for sarcopenic elderly but evidence for the most effective mode of exercise is conflicting. The objective of this study was to investigate the effects of a three-month group-based versus home-based exercise program on muscular, functional/physical performance and quality of life (QoL) across elderly with sarcopenia. 54 elderly (47 women, 7 men aged 72.87 &plusmn, 7 years) were randomly assigned to one of three interventions: supervised group (n = 18), individualized home-based exercise (n = 18) and control group (n = 18). Body composition was determined by bioelectrical impedance analysis, calf measurement with inelastic tape and strength assessments (grip and knee muscle strength) via hand-held and isokinetic dynamometers. Functional assessments included four-meter (4 m), &Tau, imed-Up and Go (TUG) and chair stand (CS) tests. QoL was assessed with Greek Sarcopenia Quality of Life (SarQol_GR) questionnaire. Outcomes were assessed at baseline, immediately post-intervention (week 12), and 3 months post-intervention (week 24). Significant group x time interactions (p &lt, 0.001) were observed in QoL, calf circumference, TUG, CS, and 4 m tests, grip and knee muscle strength. Group-based compared to home-based exercise yielded significant improvements (p &lt, 0.05) in muscle mass index, CS and 4 m tests, calf circumference, muscle strength at 12 weeks. Most improvements at 24 weeks were reported with grouped exercise. No changes were found across the control group. Results suggest group-based exercise was more effective than home-based for improving functional performance.

BACKGROUND Several etiologic factors have been postulated in overhead athletes according to their shoulder injuries, such as the scapular posture asymmetries. The measurement of the acromion border distance has been considered as reliable clinical test for evaluating the static scapula posture. The aim of this study was to quantify the differences in scapular posture between the dominant and non-dominant shoulders in two static positions in volleyball and swimmers athletes with asymptomatic shoulder injuries using the sliding calliper device. METHODS Twenty athletes involved in volleyball and swimming sports were recruited. Their mean age was 25.4±8.09 years and BMI 22.68±1.63 kg/cm2. All athletes had asymptomatic traumatic shoulder injuries. Two clinical tests were used to estimate scapula posture between the two groups of athletes using a sliding calliper device. In the first method the distance between the posterior border of the acromion in supine position and the table (AT) was measured, and in the second one the distance between the posterior border of the acromion and the wall (AW) was measured in standing. RESULTS Statistical significant differences found in AW position in the volleyball compared with swimmer athletes (F=8.883, S=0.008, P

Objective: The main objective of this study is the construction of a tool to diagnose a specific type of knee injuries, the meniscus injury, without the aid of imaging modalities. This tool exploits physician’s knowledge and experience and extracts all information needed for a diagnostic procedure. Methods: A specific type of Fuzzy Cognitive Maps, which is named Dynamic Fuzzy Cognitive Networks, is used for the implementation of diagnostic process. This method simulates the physician’s way of thinking and making decisions in order to conclude to a final diagnosis and will constitute the background of a user interface platform, named “KneeD,” designed especially as a supportive tool for the physician. It exploits information about patient history and clinical examination and the arisen symptoms and risk factors constitute the main attributes that contribute to injury identification. Results: A pilot sample of 17 patients with knee injuries who arrived at the University Hospital of Patras, in Greece, was examined by the orthopedic clinician and the diagnoses confirmed with MRI were compared to our platform’s outcomes. Results concerned a) the initial distinction between “meniscus injury” and “other disease” and b) discrimination between acute and degenerative injury for patients positive to meniscal tear from the first level. Both levels provided us with very satisfactory results in total agreement with MRI outcomes. Conclusion: The outcome of a close collaboration between engineers and medical doctors was a platform for real time diagnosing of knee injuries, which is simple, user friendly, real-time, easily accessible, fast, reliable, and low-cost. Furthermore, it could also be used as a patient storage database. The obtained results have been evaluated by orthopedic surgeons who found them very satisfactory.

Aim of this study is to assess the psychometric properties of the developed Greek version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in total knee replacement (TKR) patients.Psychometric properties of the Greek version of KOOS were evaluated according to the Consensus-based Standards Measurements Instruments (COSMIN) checklist. Patients' pre-operative clinical status and post-operative outcomes at two occasions (at discharge and 10-12 days post-operatively) were evaluated using the KOOS, KOS-ADL and SF-12 Health Survey.A comprehensive Greek KOOS was piloted and well accepted by patients and therefore administered to 60 consecutive TKR patients (mean age 72.2 ± 7.2 years, 39 women). Excellent Internal consistency, good test-retest reliability of KOOS and KOOS 5 subdomains, respectively [ICC(2-1) 0.76, 95% CI = 0.235-0.902 and 0.89, 95% CI = 0.843-0.927] was yielded. A priori hypotheses for construct validity were confirmed with KOOS score and subdomains for pain, symptoms and Everyday Living function (ADL) correlating moderately with KOS-ADL. Responsiveness for KOOS subdomains of Pain and Symptoms yielded moderate effect size (ES = 0.4).The Greek KOOS was found to be a practical and comprehensible self-reported measure for TKR patients with acceptable psychometric properties. It is therefore, recommendable for usage in future clinical trials and clinical practice. Implications for Rehabilitation The Greek version of KOOS is an essential assessment scale to evaluate not only acute injuries but also chronic knee associated conditions in a holistic perspective. The Greek KOOS has been found to be a practical and comprehensible self-reported measure for TKR patients with acceptable psychometric properties, recommendable for usage in future clinical trials and clinical practice. KOOS Greek version (downloadable at the official site http://www.koos.nu/koosgreek.pdf ) was used in the validity study.

Sarcopenia is recognized as a major health problem among older adults. This syndrome is associated with serious health consequences in terms of frailty, disability, morbidity and mortality. The aim of this study is to review sarcopenia and its impact on quality of life (QoL). MEDLINE database was searched from January to March 2016 using predefined search terms “sarcopenia”, quality of life”. Based on extensive literature search, 32 articles were identified while only 6 studies met the inclusion criteria and were associated with sarcopenia and QoL. Quality of life level was measured using generic self-reported tools; the Medical Outcomes Survey Short-form General Health Survey (SF-36) in 4 studies and EuroQol-5D instrument (EQ-5D) in 2 studies. Subjects with sarcopenia demonstrated a significantly high proportion of problems relating to several dimensions of QoL. More studies based on Sarcopenia and QoL are needed. Although the impact of sarcopenia on QoL was assessed in all studies with QoL generic instruments, it would be more insightful to utilise a disease-specific quality of life questionnaire, such as the SarQoL for sarcopenic subjects.

Objective: To identify potential subgroups amongst patients with non-specific low back pain based on a consensus list of potentially discriminatory examination items. Design: Exploratory study. Participants: A convenience sample of 106 patients with non-specific low back pain (43 males, 63 females, mean age 36 years, standard deviation 15.9 years) and 7 physiotherapists. Methods: Based on 3 focus groups and a two-round Delphi involving 23 health professionals and a random stratified sample of 150 physiotherapists, respectively, a comprehensive examination list comprising the most "discriminatory" items was compiled. Following reliability analysis, the most reliable clinical items were assessed with a sample of patients with non-specific low back pain. K-means cluster analysis was conducted for 2-, 3- and 4-cluster options to explore for meaningful homogenous subgroups. Results: The most clinically meaningful cluster was a two-subgroup option, comprising a small group (n?=?24) with more severe clinical presentation (i.e. more widespread pain, functional and sleeping problems, other symptoms, increased investigations undertaken, more severe clinical signs, etc.) and a larger less dysfunctional group (n?=?80). Conclusion: A number of potentially discriminatory clinical items were identified by health professionals and sub-classified, based on a sample of patients with non-specific low back pain, into two subgroups. However, further work is needed to validate this classification process.

Hip arthroscopy, despite recent advances in imaging, remains the gold standard in assessing the cartilage of the hip joint. As such, it can assist in staging osteonecrosis by allowing the direct visualization of the chondral surfaces of the joint. It can also supplement more established surgical techniques such as core decompression while at the same time addressing mechanical symptoms secondary to intra-articular pathology that often co-exists with the disease thereby improving the clinical outcome. This article explores the role of hip arthroscopy in osteonecrosis of the femoral head on the basis of published data and personal experience.

AIM To explore current diagnostic practice and attitudes of Greek and United Kingdom physiotherapists (PTs) on assessing low back pain (LBP) patients. METHODS Three focus groups were undertaken, followed by a structured questionnaire-type survey comprising 23 health professionals and a random stratified sample of 150 PTs, respectively. Twenty-nine themes relating to LBP diagnostic practice emerged. These were then given to 30 British PTs assessing their level of agreement with their Greek counterparts. Analysis was performed by percentage agreements and χ2 tests. RESULTS The survey was divided into three subsections; PTs' attitudes on LBP assessment, patients' attitudes and diagnostic/healthcare issues, each constituting 14, 7 and 8 statements, respectively. Over half of the statements fell within the 30%-80% agreement between Greece and United Kingdom whereas, 5 statements reported low (< 10%) and 8 statements demonstrated high (> 90%) PT percentage agreement. Similarities across British and Greek PTs were detected in history taking methods and in the way PTs feel patients perceive physiotherapy practice whereas, re-assessment was undertaken less frequently in Greece. Diagnosis according to 91% of the Greek PTs is considered a "privilege" which is exclusive for doctors in Greece (only 17% British PTs agreed) and is accompanied with a great overuse of medical investigations. Forty percent of Greek PTs (compared to 0% of British) consider themselves as "executers", being unable to interfere with treatment plan, possibly implying lack of autonomy. CONCLUSION Although similarities on history taking methods and on patients' attitudes were detected across both groups, gross differences were found in re-assessment procedures and diagnostic issues between Greek and British physiotherapists, highlighting differences in service delivery and professional autonomy.

The aim of this paper is to create an integrated meniscus injury diagnostic model, which by exploiting information about patient history and clinical examination made by physicians concludes to a final diagnosis using Fuzzy Cognitive Maps. Mechanisms of injury and symptoms combined with test results constitute the first level modelled with FCM. The output of this level decides if the patient has a meniscus tear or not. The second level decides if the injury is acute or degenerative with the help of risk factors using Competitive Fuzzy Cognitive Maps in order to conclude to only one decision. The results obtained by the model are very promising without requiring sending the patient for MRI (Magnetic Resonance Imaging) which is of utmost importance in diagnosing soft tissue injuries.

The purpose of this study is to present our experience with the technique, the problems and the potential pitfalls of arthroscopically assisted retrograde femoral nailing for supracondylar femoral fractures. In a 2-year period, nine patients (seven women, two men, average age 72 years) with supracondylar femoral fractures were treated in our department with a retrograde nailing under arthroscopic control. The mean operative time was 63.8 min (42-84 min) and the mean follow up period was 34.5 months (ranged 12-52). Solid union of the fracture was achieved in all patients without additional intervention, in 14 weeks (range 12-18). There was no malalignment (more than 5 degrees in any plane) or implant failure. In conclusion we believe that the arthroscopically assisted technique is a very good method to treat supracondylar fractures of the femur. It has very low morbidity since the knee is not opened through the operation, and the surgeon has the ability to inspect the joint for any additional damage. It is very helpful in multitrauma patients and in young patients, where the precision of the entry point is critical. However, we do not recommend the technique in intraarticular fractures because the reduction is difficult and the fixation is performed with safety only under direct vision.

Objectives: Although the short-term results of supracondylar periprosthetic fractures treated with retrograde nailing have been satisfactory, there is always a concern about the long-term survival of the prosthesis. The aim of the study was to evaluate fracture healing and knee functional outcome with a follow-up time of at least 2 years in periprosthetic fractures of the knee treated with a supracondylar nail. Design: Cohort study. Patients: There were 9 patients with 10 periprosthetic fractures. In 1 patient, the fracture occurred intraoperatively. In the others, the time between the total knee arthroplasty and the periprosthetic fracture ranged between 2 weeks and 7 years (average time: 2.78 years). The mean follow-up was 34.5 months (25-52 months). Main Outcome Measurements: The Western Ontario and McMaster Universities index was used to evaluate the functional result postoperatively using the paired t test as the statistical test. Fracture union was assessed with plain x-rays. Results: All the fractures united within 3 months. One fracture united in extreme valgus (35°) and was revised to a stemmed total knee replacement. There were no infections and no prosthesis loosening. The paired t test before the fracture and after the operation demonstrated no statistically significant differences; however, there was a trend toward lower functional score postoperatively. Conclusions: It appears that retrograde nailing is a reliable technique to treat periprosthetic supracondylar fractures. It provides adequate stability until fracture union. The morbidity of the operation is minimal, and the complication rate is low. The midterm results in our study showed that none of the prostheses required revision. In our opinion, it is the treatment of choice for a periprosthetic fracture when the prosthesis is stable.

We present the outcome of treating complex injuries of the elbow with the "Orthofix" external fixator in patients where the condition of the soft tissues did not permit extensile surgical approach or where the internal fixation would not be stable enough to permit safe early joint mobilization postoperatively. Eight patients were treated, three with supra-intercondylar fracture in the presence of marked osteoporosis and five with fracture-dislocation of the elbow and excessive soft tissue impairment. The fixator was applied for a mean of 8.5 weeks (5-13 weeks). Great care was taken to use the appropriate technique in applying the fixator, especially to define the correct centre of rotation. All the fractures were united, and no instability of the joint was noted. All the patients maintained a functional range of motion, with lack of extension less than 30 degrees and flexion more than 120 degrees . One patient who developed transient palsy of the radial nerve and two patients who developed pin track infection were treated with oral antibiotics. Despite the technical difficulties, external fixation of the elbow could be a salvage procedure in difficult cases of elbow trauma, where open procedures are not indicated.

Objectives Total knee replacement (TKR) has a beneficial effect on patients' functional ability; however, incidence of falls and deficits on proprioception are not restored even 1-year after surgery. Early and intensive exercise post-TKR has received limited endorsement in the literature. The aim of this review was to systemically identify and critically appraise clinical studies investigating the effect of sensori-motor training on functional and balance performance in TKR patients. Data sources The electronic databases Cochrane Library, MEDLINE, EMBASE, CINAHL, PEDro and the register of current controlled trials were searched up to September 2014. Review methods Two independent reviewers used predefined inclusion and exclusion criteria to identify all eligible articles. Eligible articles were summarized and critically reviewed, using the PEDro scale. Results Two hundred and seventy six articles were screened, six were included. The studies, presented the results of 409 patients (269 intervention, 140 control). A range of rehabilitation protocols were defined by components of proprioception, postural control, balance perturbation and coordination. All studies supported the use of sensori-motor training as an additional element in patients' rehabilitation protocols. Clinical performance-based tests (more than relevant patient-reported measures) showed that functional ability and balance were improved compared to controls. The robustness of evidence was compromised because most of the studies were underpowered. Conclusions Limited robust (Ia) evidence supports the equal effectiveness of functional rehabilitation program as a functional rehabilitation enhanced with sensori-motor elements in patients post-TKR. However, dose-response parameters of exercise eliciting improvement warrant further investigation.

The outcome of 169 fractures of the distal radius in adults under the age of 50 were assessed at least 18 months after injury (mean follow-up, 4.9 years) using a validated, patient-based outcome questionnaire. The questionnaire responses demonstrated that neither the Frykman nor the Mayo classifications of distal radial fractures predicted outcome. Fracture union with more than 10° of dorsal tilt was associated with increased difficulty with everyday activities and work, while union with a step in the radiocarpal articular surface was associated with loss of wrist mobility and difficulty with fine dextrous tasks. No measure of either intra- or extra-articular malunion influenced the severity or frequency of persistent wrist pain.

A case of chondral lesion of the medial femoral condyle caused by a bioabsorbable Mitek RapidLoc meniscal repair implant is presented. Meniscal repair was quite successful, but migration of one of the implanted fixation devices resulted in chondral damage, 12 months postoperatively. All orthopaedic surgeons using these new devices should be aware of the possibility of chondral damage of the adjacent femoral condyles.

Background and Purpose In Greece, as in many countries, there is a scarcity of evidence in the type of physiotherapy services offered for the rehabilitation of total knee replacement (TKR). Despite the number of TKRs annually performed in Greece (over 10,000), there are no available clinical guidelines as to the content of best physiotherapy practice. The aim of this nationwide survey undertaken by physiotherapists treating TKR patients post-operatively was to record standard practice and services available in Greece. Methods Design: cross-country survey Ten per cent of all registered physiotherapists working in public/private sectors were recruited. The developed survey comprised of questions regarding therapists' profile, protocols implemented at different stages of rehabilitation and the aims and modalities used. Results A 58.7% response rate was achieved, where 36% (47/132) of respondents were treating patients in the inpatient phase and 64% (85/132) after hospital discharge. Patients in Greece are discharged with a home-based exercise program (56.7%) and, to a lesser extent, are referred to rehabilitation centres (13.3%). Strengthening, range of movement and functionality seemed to be the primary goals especially in the inpatient phase, whereas in the outpatient phase, apart from the larger differences identified, functionality and balance training were more frequently reported. Conclusions No significant variations in practice were found during inpatient rehabilitation, whilst there seemed to be diversity across outpatient physiotherapy programs. The current survey suggests that patient's general health and psychological and behavioural issues are the criteria by which physiotherapists select the volume of implemented exercise and progression. However, no specific guidelines were followed. Copyright © 2016 John Wiley & Sons, Ltd.

Objective: To investigate the inter-tester reliability of a nonspecific low back pain examination procedure, for sub-classifying non-specific low back pain. Design: Reliability study. Participants: Thirty patients with non-specific low back pain (12 males, 18 females, mean age 27.7 years, standard deviation 10.3) and 7 physiotherapists (raters). Methods: Based on a health professionals' consensus via focus groups and a Delphi servey, an examination procedure was developed comprising 206 items discriminatory for nonspecific low back pain, 108 of which were from the History (clinical questions) and 98 from the Physical Examination (clinical tests) section. Utilizing this procedure, each patient was examined by a blinded pair of raters. Results: Moderate to excellent agreement was obtained in 125 (61%) items (77 History and 48 Physical Examination items), 47 of which obtained substantial or excellent agreement (kappa > 0.61), 37 moderate agreement (kappa between 0.41 and 0.6), and 41 excellent percentage agreements. Poor reliability (kappa

Rationale, aims and objectives Developing homogenous low back pain (LBP) classification groups is recommended for enhancing clinical outcomes. However, an important step towards the development of specific subgroups is the selection and consensus agreement among health professionals on the discriminatory clinical items (sings and symptoms) that should be included in the classification process. Thus, this study's objective was to develop a list of clinical features for the assessment of LBP by health care providers within Greece, which are believed to be discriminatory in identifying LBP subgroups. Methods A random sample stratified by geographical region and work status of 150 Greek physiotherapists (PTs) participated in a two-round Delphi study. PTs were asked to obtain consensus and hierarchy, the most important items out of a list of evaluating/diagnostic features believed to be discriminatory for LBP patients. These items included 80 clinical features and were generated in by PTs and doctors previous work. Results Second-round questionnaires were returned by 112 PTs (74.6% response rate). A total of 66 clinical features were rated as important discriminatory items in LBP assessment. Clinical items included characteristics of present symptoms and the history's condition, general medical history, information regarding patient function, patients' attitudes regarding movement, diagnosis, expectations, fear-avoidance beliefs as well as aspects of a physical examination including observation, active and passive movements, neurological and muscular examination. Conclusions This is the first study identifying important clinical items for LBP patients in Greece. It may be that these features are ‘discriminatory’ for different LBP subsets; however, further research is needed.

Background The mechanoreceptors located in anterior cruciate ligament (ACL) constitute an afferent source of information toward the central nervous system. It has been proposed that ACL deficiency causes a disturbance in neuromuscular control, affects central programs and consequently the motor response resulting in serious dysfunction of the injured limb. Purpose The objective of this study was to investigate whether chronic anterior cruciate ligament injury causes plastic changes in brain activation patterns. Study Design Case control study; Level of evidence, 3. Methods Seventeen right leg–dominant male participants with chronic anterior cruciate ligament deficiency and 18 matched healthy male participants with no special sport or habitual physical activity participated in this study. Patient selection criteria comprised a complete right unilateral anterior cruciate ligament rupture ≥6 months before testing. Brain activation was examined by using functional magnetic resonance imaging technique (1.5-T scanner). Results Results show that patients with anterior cruciate ligament deficiency had diminished activation in several sensorimotor cortical areas and increased activation in 3 areas compared with controls: presupplementary motor area, posterior secondary somatosensory area, and posterior inferior temporal gyrus. Conclusion The current study reveals that anterior cruciate ligament deficiency can cause reorganization of the central nervous system, suggesting that such an injury might be regarded as a neurophysiologic dysfunction, not a simple peripheral musculoskeletal injury. This evidence could explain clinical symptoms that accompany this type of injury and lead to severe dysfunction. Understanding the pattern of brain activation after a peripheral joint injury such as anterior cruciate ligament injury lead to new standards in rehabilitation and motor control learning with a wide application in a number of clinical and research areas (eg, surgical procedures, patient re-education, athletic training, etc).

A 67-year-old woman presented with erythema and swelling over her left elbow. She felt pain during palpation of the olecranon, while the range of elbow motion was slightly reduced (02 in circle-302 in circle-1302 in circle). She had been treated conservatively elsewhere for 3 months with nonsteroidal anti-inflammatory drugs and splint immobilization. Radiographs and computed tomography showed an osteolytic area over the olecranon with cortex disruption. She underwent open biopsy of the olecranon, and the histologic features were compatible with tuberculosis. Erythrocyte sedimentation rate was elevated and she had a positive Mantoux test (14 mm). She mentioned no history of pulmonary disease and had a normal chest radiograph. She received antituberculous treatment (isoniazid, rifambin, and pyrazinamide) for 2 months without obvious improvement. She underwent surgical debridement of the olecranon while she continued antituberculous treatment for 12 months, discontinuing pyrazinamide after the third month. After the completion of antituberculous treatment, the patient was pain-free, without local signs of infection and with improved range of motion (02 in circle-202 in circle-1452 in circle). Early diagnosis and treatment of olecranon tuberculosis is of great value, and the prognosis is good when there is no spread in the elbow joint.

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.

The literature discussing the management of adults with late sequelae of knee-joint septic arthritis is rather sparse. This is in marked contrast to the plethora of references regarding reconstructive hip surgery for the late sequelae of joint infection during childhood. Appropriate and timely treatment of septic arthritis seldom results in devastating complications such as joint destruction with concomitant dislocation. Such complications are currently rare in countries with well-developed health systems, possibly because there is a high index of suspicion and the appropriate treatment is highly effective. We report a case of the management of a neglected posterior knee dislocation as a late sequela of septic arthritis in adolescence. The apparent rarity of such a devastating complication and the fact that it represents a challenging therapeutic problem could be of significant educational value for an orthopedic surgeon confronted with a similar case, enabling him to accurately assess the patient preoperatively and plan the treatment stages using the Ilizarov device to enhance a valuable functional outcome.

Introduction A patient with a neglected, compound acutely ruptured false aneurysm of the brachial artery which developed after a periprosthetic fracture of the right humerus, is reported. Case presentation An 84-year-old Greek woman underwent right shoulder hemiarthroplasty 2 years before a periprosthetic fracture which was treated conservatively in another hospital. After removing the U-slab herself, she noticed the development of an ulcer on the mid-humerus, with continuous oozing but no fever. This led to above-elbow amputation in an attempt to save the patient's life. Conclusion It is hoped that by awareness of such a possibility coupled with an early diagnosis based on the clinical picture and imaging modalities, such unfortunate results can be avoided in the future. In case of increasing displacement at the fracture site and excessive local swelling, the possibility of the presence of a false brachial aneurysm should be ruled out despite the presence of normal perfusion of the hand and palpable radial and ulnar pulses.

Objective Although anterior surgery for cervical spine injuries is a widespread procedure, articles regarding its overall complications are infrequently published in the literature. In the current study we focus on the complications encountered after anterior instrumented stabilization of cervical spine injuries and we discuss ways to minimize them. Patients and methods Patients with unstable lower cervical spine injuries who underwent anterior surgery over a 15-year period were identified and 74 patients with adequate follow-up were included in the study. Indication for surgery was set by the instability criteria of White and Panjabi. Demographic information, initial neurological examination, surgical reports, imaging findings and follow-up records were evaluated. Results Complications were classified as intraoperative (technique-related) and postoperative. Although radiological “complications” were noted, they had no or minor clinical consequences for the patient. We identified 9 patients with clinically significant complications: no purchase of the screws, late angulation deformity, screw breakage, backout of the screws and postoperative hematoma. Overall, 3 out of 74 patients (4%) were reoperated due to significant screw backout causing dysphagia, no purchase of the screws being completely in the adjacent disc and screw breakage, respectively. Conclusion Anterior surgery for cervical spine injuries can present several complications, yet the technique is in a way permissive, even during the learning curve. Considering the significant morbidity of these patients, the reported rate of clinically significant complications is considered acceptable, and it could be further minimized by good preoperative planning, careful surgical technique and the use of modern implants and instrumentation.
