Reliability and validity of the Greek adaptation of the Modified Barthel Index in neurorehabilitation patients.

BACKGROUND: The Modified Barthel Index (MBI) (Shah version) is a widely used functional assessment measure with greater sensitivity and improved reliability compared to the original Barthel Index. AIM: The aim of this study was to adapt the MBI for use in Greece and measure its reliability and validity on a Greek neuro-rehabilitation population. DESIGN: Observational study. SETTING: KAT Hospital Rehabilitation Clinic and National Rehabilitation Centre in Athens, Greece. POPULATION: A total of 100 rehabilitation inpatients and outpatients consisting of 50 stroke and 50 spinal cord injury (SCI) patients were evaluated. METHODS: The MBI underwent the proper translation and cultural adaptation procedure as required by the World Health Organization and was administered to 100 rehabilitation patients. For criterion validity evaluation all patients were also assessed with the Katz Index of Independence in Activities of Daily Living (Katz Index) and the 36-Item Short Form Survey (SF-36) physical functioning subscale, both questionnaires having been validated for use in Greece. RESULTS: The unidimensionality solution was rejected and a two- factor solution was adopted based on exploratory and confirmatory factor analysis (Factor 1 - Transfers and Activities of Daily Living, Factor 2 - Mobility). Very high correlation was presented between the Katz Index score and the Greek MBI Factor 1 (r=0.888, P<0.001) and total score (r=0.873 P<0.001) respectively and high with MBI Factor 2 (r=0.561, P<0.001). High correlation was observed between the SF-36 physical functioning subscale score with MBI Factor 1 (r=0.522, P<0.001), MBI Factor 2 (r=0.590, P<0.001) and MBI Total score (r=0.580, P<0.001). The internal consistency of the MBI Factor 1, Factor 2 and Total score was 0.920, 0.860 and 0.923 respectively. Test-retest reliability was remarkably consistent (total score 0.994, P<0.001). CONCLUSIONS: The Greek version of the Modified Barthel Index has been found to exhibit satisfactory levels of reliability and validity. CLINICAL REHABILITATION IMPACT: The Greek MBI adaptation is an adequate and useful instrument for use on Greek neuro-rehabilitation patients.

Development and validation of a fall risk Questionnaire in Greek community-dwelling individuals over 60 years old.

Objectives: The purpose of this study was to develop a questionnaire that can reliably recognize Greek individuals over the age of 60 with increased risk of falls. Methods: An 11-item self-reported Questionnaire (LRMS) was developed and delivered to 200 individuals. Collected data were compared to Timed Up and Go (TUG), Falls Efficacy Scale-International (FES-I), Tinetti Assessment Tool, Geriatric Depression Scale-15 (GDS-15) and Morse fall scale. The results were statistically analyzed. Results: Correlation between LRMS and the examined tools was high TUG (r=0.831), FES-I (r=-0.820), Tinetti balance (r=-0.812), Tinetti gait (r=-0.789), GDS-15 (r=-0.562), and Morse fall scale (r=0.795). Cronbach's alpha for LRMS total score was 0.807. ICC of the LRMS total score was 0.991. The area under the curve of LRMS was 0.930 (cut-off point 10.5, 95% C.I. 0.88 - 0.98, p<0.001, sensitivity=86%, specificity=98%) with TUG as gold standard, 0.919 (cut-off point 11.5, 95% C.I. 0.88 - 0.96, p<0.001, sensitivity=85%, specificity=89%) with FES-I and 0.947 (cut-off point 10.5, 95% C.I. 0.91 - 0.98, p<0.001, sensitivity=93%, specificity=91%) with Tinetti. Conclusions: The LRMS Questionnaire showed sufficient internal consistency, excellent test-retest reliability and high correlation with the already established tools for fall risk assessment. It is short and easy to use without assistance from specially trained personnel.

What is the optimal surgical treatment for Neer type IIB (IIC) distal clavicle fractures? A systematic review and meta-analysis.

BACKGROUND: The purpose of the present study was to systematically review the current treatment strategies for the treatment of Neer type IIB distal clavicle fractures in terms of functional outcome and complication rates and to examine the most appropriate surgical method by comparing all the available surgical techniques and implants. METHODS: We performed a systematic review of the existing literature (2000-2021) in accordance with the PRISMA statement. We searched PubMed, Scopus, Web of Science, Research Gate and Google Scholar using the general terms 'distal AND clavicle AND fracture' to capture as many reports as possible. The MINORS tool was used to assess the risk of bias of the nonrandomized studies. We categorized the reported surgical techniques into four main types: open or arthroscopic coracoclavicular (CC) stabilization, locking plate fixation with or without CC augmentation, hook plate fixation and acromioclavicular joint (ACJ) transfixation. We reported findings for two main outcomes: clinical results and complication rates categorized into major and minor. RESULTS: Our database search yielded a total of 630 records; 34 studies were appropriate for qualitative analysis. There were 790 patients, with a mean age of 40.1 years, a female percentage of 37% and a mean follow-up period of 29.3 months. In total, 132 patients received a hook plate, 252 received a locking plate, 368 received CC stabilization and 41 received transacromial transfixation. All studies were retrospective and had fair MINORS scores. Locking plate, CC stabilization and ACJ transfixation showed similar clinical results but were much better than hook plate fixation; CC augmentation did not significantly improve the outcome of locking plate fixation. The rate of major complications was similar among groups; hook plate and AC joint transfixation had the worst rates of minor complications. Open CC techniques were slightly better than arthroscopic techniques. CONCLUSIONS: The present systematic review for the optimal fixation method for Neer type IIB fractures of the distal clavicle showed similar major complication rates among techniques; the hook plate technique demonstrated inferior clinical results to other techniques. Open CC stabilization and locking plate fixation without CC augmentation seem to be the best available treatment options.

Effect of Calcium and Vitamin D Supplementation With and Without Collagen Peptides on Volumetric and Areal Bone Mineral Density, Bone Geometry and Bone Turnover in Postmenopausal Women With Osteopenia.

Collagen peptides (CPs) have been shown to potentially have a role as a treatment option in osteopenia. In the present randomized prospective study, we examined the effect of calcium, vitamin D with and without CPs supplementation on changes in volumetric bone mineral density (vBMD) and bone geometry assessed by peripheral quantitative computed tomography at the tibia, areal bone mineral density (aBMD) assessed by dual-energy X-ray absorptiometry at the lumbar spine and the hip and bone turnover markers over 12-mo. Fifty-one postmenopausal women with osteopenia were allocated to Group A who received orally 5 g CPs, 500 mg calcium and 400 IU vitamin D3 and Group B who received the same dose of calcium and vitamin D3 per day. The primary endpoint was the change of trabecular bone mineral content (BMC) and vBMD after 12-mo supplementation in Groups A and B. At the trabecular site (4% of the tibia length), Group A had a significant increase of total BMC by 1.96 ± 2.41% and cross-sectional area by 2.58 ± 3.91%, trabecular BMC by 5.24 ± 6.48%, cross-sectional area by 2.58 ± 3.91% and vBMD by 2.54 ± 3.43% and a higher % change of these parameters at 12 mo in comparison to Group B (p < 0.01, p = 0.04, p < 0.01, p = 0.04, p = 0.02, respectively). At the cortical site (38% of the tibia length), total and cortical vBMD increased by 1.01 ± 2.57% and 0.67 ± 1.71%. Furthermore, the mean aBMD at the spine was higher (p = 0.01), while bone markers decreased in Group A compared to Group B. The present study shows improvement of trabecular and cortical parameters as assessed by peripheral quantitative computed tomography at the tibia, prevention of aBMD decline and decrease of bone turnover after 12-mo supplementation with calcium, vitamin D with CPs.

Comparison of Bone-Patella Tendon-Bone and Four-Strand Hamstring Tendon Grafts for Anterior Cruciate Ligament Reconstruction: A Prospective Study.

Introduction To date, the proper choice of graft for anterior cruciate ligament (ACL) reconstruction remains a matter of conflict. We aimed to compare the clinical and functional outcomes of the two most commonly utilized autografts, bone-patella tendon-bone (BPTB) and four-strand hamstring tendon (HT) graft, at 6 and 12 months after surgery. Methods In a prospective randomized study, we included a total of 60 patients undergoing ACL reconstruction, thirty in BPTB and thirty in HT group. All patients were amateur athletes and were evaluated at 6 and12 months after surgery for: (a)postoperativefunctionality of the operated knee by the Tegner, the Lysholm and the International Knee Documentation Committee (IKDC) scoring scales, (b) anterior cruciate ligament (ACL) instability of the operated knee compared to the healthy contralateral knee by the KT-1000 arthrometer and (c) theextension and flexion muscle strength of the operated knee by a CYBEXisokinetic dynamometer.  Results Patients in the two groups did not differ regarding demographics, and pre-injury functionality status. Significantly more patients in the HT group (n=6) compared to the BPTB group (n=1) experienced ACL re-rupture and underwent revision surgery before follow-up end (p=0.044). All patients, regardless of graft, showed significant improvement within each group of functional assessments by Lysholm, Tegner and IKDC scores, as well as of Cybex measurements -with an increase of peak torque at 60° extension and 180°extension and 60° flexion and 180° flexion- at 12 months compared to 6 months follow-up (p<0.05). However, there was no difference between the two groups regarding knee function improvement or extension measurements neither at 6 nor 12 months. Contrarily, the BPTB graft group had higher values of peak torque (Nm) at 60° and 180° flexion compared to the HT group, both at 6 (p=0.014 and 0.029, respectively) and 12 months (p=0.033 and 0.030, respectively). Postoperative stability was similar between the two groups at 12 months (p=0.519). Conclusion Both BPTB and HT grafts present with benefits and drawbacks and remain viable autograft options for primary ACL reconstruction as each has, although HT grafts seem to be more susceptible to re-rupture. The graft selection should be based on the needs and activities of each patient.

A Systematic Approach for Stronger Documentation of Anterior Cruciate Ligament Graft Choice.

Numerous studies have focused on determining the optimal choice between the two most used anterior cruciate ligament (ACL) reconstruction autografts. In order to address this matter, we performed a systematic review of every meta-analysis published on the PubMed platform between 2001 and 2020, comparing the functional outcomes, the static stability parameters, as well as the postoperative and long-term complications of the patellar tendon (BPTB) autograft and hamstrings (HT). We retrieved a total of 26 meta-analyses that met our criteria, and the characteristics and outcomes of every meta-analysis, as well as subgroup analysis regarding the type of the study design, number of strands of HT autograft, and fixation method, were extensively recorded. The majority of the meta-analyses showed that there were no significant differences between BPTB and HT in terms of functional outcomes and static stability parameters while HT autografts seem to be superior to BPTB regarding kneeling pain and anterior knee pain. Other outcomes seem to be affected by the number of strands of the HT autograft, the fixation technique, and the type of study design, indicating superiority of the four-strand HT autograft with the use of an extra-cortical button fixation. Overall, there is no clear superiority of BPTB over HT autografts for ACL reconstruction, as both types present similar outcomes in the majority of postoperative parameters. Autograft selection should be individualized according to each patient's needs and more RCTs are warranted in order to reach safer results on the appropriate autograft type.

Validity and reliability of the Greek version of the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form.

BACKGROUND: The aim of our study is to prove the validity and reliability of the Greek translated version of the self-report section of the American Shoulder and Elbow Surgeons (ASES) questionnaire. METHODS: A total of 108 patients with various shoulder disorders were evaluated at two different orthopedic centers. All patients answered the Greek ASES questionnaire as well as the previously validated Greek version of the Disability Arm Shoulder and Hand score. Three days after the first evaluation, a subgroup of 40 individuals was randomly selected to complete again the Greek ASES text to prove its reliability, after the test-retest procedure. Reliability was tested with Cronbach's alpha, stability by calculating the intraclass correlation coefficient and by Blant Altman plot and structural validity with the confirmatory factor analysis. RESULTS: The internal consistency of the ASES functional score and the ASES total score was 0.925 and 0.750 respectively. The intraclass correlation coefficient between initial assessment and reassessment of the ASES functional and total score was 0.951 and 0.938 (P < .001), respectively. The correlation coefficients correlation between the ASES functional and total scores with DASH total score were -0.881 and -0.759 (P < .001), respectively. CONCLUSIONS: The Greek ASES version proved to be equivalent to the English original version in evaluating different shoulder disorders in the Greek population.

Teriparatide Treatment in Patients with Pregnancy- and Lactation-Associated Osteoporosis.

Pregnancy- and lactation-associated osteoporosis (PLO) is a rare disease, presenting in most cases with severe back pain due to low energy vertebral fractures (VFs). Our purpose was to assess the effect of teriparatide (TPTD) vs. conventional management on areal bone mineral density (aBMD) and trabecular bone score (TBS) in patients with PLO. A multicenter retrospective cohort study concerning premenopausal women with PLO. Nineteen women were treated with TPTD (20 µg/day) (group A) plus calcium and vitamin D and eight women with calcium and vitamin D only (group B) for up to 24 months. The primary end-point was between group differences in lumbar spine (LS) and total hip (TH) aBMD, and TBS at 12 and 24 months. Patients in group A had sustained a median of 4.0 VFs (3-9) vs. 2.5 VFs (1-10) in group B (p = 0.02). At 12 months, patients on TPTD vs. controls achieved a mean aBMD increase of 20.9  ±  11.9% vs. 6.2  ±  4.8% at the LS (p < 0.001), 10.0  ±  11.6% vs. 5.8  ±  2.8% at the TH (p = 0.43), and 6.7  ±  6.9% vs. 0.9  ±  3.7% in TBS (p = 0.09), respectively. At 24 months, seven patients on TPTD and six controls achieved a mean LS aBMD increase of 32.9  ±  13.4% vs. 12.2  ±  4.2% (p = 0.001). P1NP levels during the first month of TPTD treatment were positively correlated with the 1-year LS aBMD change (r = 0.68, p = 0.03). No new clinical fractures occurred while on-treatment. In patients with PLO, TPTD treatment resulted in significantly greater increases in LS aBMD compared with calcium and vitamin D supplementation at 12 and 24 months.

Chronic Lateral Ankle Instability in Highly Active Patients: A Treatment Algorithm Based on the Arthroscopic Assessment of the Calcaneofibular Ligament.

Background Ankle sprains are common injuries that may recur as chronic conditions. We aim to describe a treatment algorithm for chronic lateral ankle instability based on the arthroscopic findings of the calcaneofibular ligament (CFL). Methods We assessed 67 highly active patients with chronic lateral ankle instability. They were recreational athletes or active military personnel. After clinical examination, they were all investigated further with MRI scans and stress views. Diagnostic arthroscopy followed, where the integrity of the CFL was assessed. Patients with an intact CFL were placed in group A while those with CFL tears in group B. Concomitant intra-articular pathologies, if present, were treated arthroscopically. CFL tears mandated that modified Broström-Gould reconstruction would follow. The American Orthopaedic Foot and Ankle Society (AOFAS) and Tegner scores were noted post-injury and during the 24-month follow-up. Results A total of 37 patients were put in group A and 30 in group B. The posterior talofibular ligament was intact in both groups. Synovitis and scar tissue were more common in group A (p = 0.01) compared to group B. Overall, no postoperative ankle instability or relapsing ankle sprain was documented. Both groups demonstrated significant improvement in their Tegner (p = 0.009) and AOFAS scores (p = 0.001) during their 24 months follow-up. Inter-rater reliability for CFL tears was moderate on clinical examination (k = 0.514) and fair on MRI, in conjunction with ankle arthroscopy (k = 0.357). Conclusion Our proposed algorithm offered a reliable pathway for accurate evaluation and successful treatment of chronic lateral ankle instability in high-demand groups.

Injury to the Medial Superior Genicular Artery After Isolated Posterior Cruciate Ligament Reconstruction: A Case Report.

CASE: A 19-year-old male patient with isolated posterior cruciate ligament (PCL) rupture underwent arthroscopic reconstruction using reinforced synthetic ligament (LARS system). Three weeks postoperatively, he presented with active bleeding from the medial side of his knee, near the proximal interference screw. An angiogram revealed extravasation from the medial superior genicular artery which was successfully embolized. One week later, he returned with active bleeding from the same area, located just under the initial coiling; a second embolization during superselective angiography was successful. CONCLUSION: Although rare, minor vascular injuries are a risk inherent to PCL surgery.

Platelet-rich Plasma and Mesenchymal Stem Cells Local Infiltration Promote Functional Recovery and Histological Repair of Experimentally Transected Sciatic Nerves in Rats.

Introduction Platelet-rich plasma (PRP) products and mesenchymal stem cells (MSCs) seem to have a significant potential as neurogenic therapeutic modulator systems. This study aimed to investigate such biological blood derivatives that could enhance nerve regeneration when applied locally in the primary repair of peripheral nerve transection of an experimental rat model. Methods A total of 42 two-month-old male Wistar rats were divided into three "treatment" groups (control, PRP, and MSCs). All the subjects were operated under anesthesia, and the surgical site was infiltrated with either normal saline, PRP derived from the animal's peripheral blood, or MSCs derived from the animal's femoral bone marrow. All three groups were also sub-divided into two sub-groups based on the post-operative administration of Non-steroidal anti-inflammatory drugs (NSAIDs) or not in order to evaluate the effect of NSAIDs on the final outcome. Three months post-surgery, electromyography evaluation of both hind limbs (right operated and left non-operated) was performed. The animals were euthanized, and nerve repair specimens were prepared for histology. Results PRP group had a significant effect (p<0.05) on the sciatic nerve repair when compared with the control group, whereas the MSC group had a positive effect but was not statistically significant (p=0.2). The number of counted neural axons at the area distal to the nerve repair site were significantly repetitive (p<0.05) in both the PRP and MSC groups when compared with the control group. Conclusions Both PRP and MSCs appear to play an essential role in the enhancement of nerve repair in terms of functionality and histology. MSCs group demonstrated a positive effect, whereas the PRP group showed statistically significant better results.

Effect of calcium and vitamin D supplementation with and without collagen peptides on bone turnover in postmenopausal women with osteopenia.

OBJECTIVES: Collagen peptides (CPs) seem to exert beneficial effects on bone and may have a role as a treatment option. In the present randomized prospective study, we aimed to examine the efficacy, as expressed by changes in P1NP and CTX, and the tolerability of 3-month supplementation of calcium, vitamin D with or without bioactive CPs in postmenopausal women with osteopenia. METHODS: Fifty-one female, postmenopausal women with osteopenia were allocated to two groups: Group A received a sachet containing 5 g CPs, 3.6 g calcium lactate (equivalent to 500 mg of elemental calcium) and 400 IU vitamin D3 and group B received a chewable tablet containing 1.25 g calcium carbonate (equivalent to 500 mg of elemental calcium) and 400 IU vitamin D3 daily. RESULTS: In group A, the P1NP levels significantly decreased by 13.1% (p<0.001) and CTX levels decreased by 11.4% (p=0.058) within 3 months of supplementation. In group B, P1NP and CTX did not change. Group A presented better compliance in comparison to group B and no adverse events contrary to group B. CONCLUSIONS: These findings may reflect the reduction of the increased bone turnover in postmenopausal women with the use of calcium, vitamin D and CPs supplements. The addition of CPs in a calcium and vitamin D supplement may enhance its already known positive effect on bone metabolism. Clinical Trial ID: NCT03999775.

The combination of microfracture with induction of Wnt / ß- Catenin pathway, leads to enhanced cartilage regeneration.

INTRODUCTION: Microfracture does not lead to complete healing of full-thickness cartilage defects. The aim of this study was to evaluate the effect of modifying Wnt/ß-catenin signaling following microfracture, on the restoration of a full-thickness cartilage defect in a rabbit model. The modification of the canonical Wnt pathway was achieved through per os administration of lithium carbonate, which is an intracellular inhibitor of glycogen synthase kinase 3-ß (Gsk3-ß) and therefore induces Wnt/ß-catenin signaling. MATERIALS AND METHODS: Full-thickness cartilage defects of 4 mm in diameter were created in the patellar groove of the right femurs of 18 male New Zealand white rabbits. The rabbits were divided into three groups of six (n = 6) based on post-surgery treatment differences, as follows: microfracture only (group 1), microfracture plus lithium carbonate 7 mM in the drinking water for 1 week (group 2), microfracture plus lithium carbonate 7 mM in the drinking water for 4 weeks (group 3). All animals were sacrificed 9 weeks after surgery. The outcome was assessed histologically, by using the International Cartilage Repair Society (ICRS) visual histological scale. Immunohistochemistry for type II collagen was also conducted. RESULTS: Statistical analysis of the histological ICRS scores showed that group 3 was significantly superior to group 1 in four out of six ICRS categories, while group 2 was superior to 1 in only two out of six. CONCLUSION: The combination of microfracture and systematic administration of lithium carbonate 7 mM for 4 weeks shows statistically significant superiority in four out of six ICRS categories compared with microfracture only for the treatment of full-thickness cartilage defects in a rabbit experimental model.

Minimally invasive treatment of femoral head avascular necrosis in a beta thalassemia carrier. A case-report.

Avascular necrosis (AVNFH) of the femoral head is a relatively rare condition linked with numerous causes. If not treated promptly then arthritis may be inevitable, making hip replacement the only treatment option. In this case report we present a young AVNFH patient with history of heterozygous beta thalassemia. To our knowledge this is the second case where a thalassemia carrier presents AVNFH. Due to his age and pre-collapse stage, we elected to use a minimally invasive, femoral head sparing technique. Therefore, the patient underwent arthroscopy and fluoroscopy assisted core decompression followed by autograft and demineralized bone matrix application. Recovery was uneventful and a year after surgery femoral collapse did not progress. Moreover, the patient was pain free and capable of participating in sport activities. Even though it is difficult to describe a pathway linking heterozygous beta thalassemia with AVNFH, a possible relation between them cannot be discarded.

Association between abductor muscle strength and functional outcomes in hip-fractured patients: a cross-sectional study.

OBJECTIVES: To explore associations between abductor strength and functionality in hip-fracture patients. METHODS: Ninety-six participants (70-84 years) followed a 12-week physiotherapy programme emphasizing hip abductor strengthening. The abductor's isometric strength, the hip strength asymmetry (HSA), expressing the ratio of abductor strength in the fractured versus the contralateral hip, and the patients' functional level were recorded 3 months post-intervention. Functionality was assessed using the Timed Up & Go (TUG) test and the Lower Extremity Functional Scale (LEFS-Greek). RESULTS: Abductor isometric strength and HSA were correlated negatively with TUG test (Pearson's r: -0.881 and -0.810, respectively; p⟨0.001) and positively with LEFS-Greek (Spearman's ρ: 0.668 and 0.404, respectively; p⟨0.001). Of all independent variables examined, abductor isometric strength was the main predictor of functional capacity, being strongly and directly associated with a faster TUG test time (p⟨0.001) and a better LEFS-Greek score (p⟨0.001). Abductor's isometric strength and age explained 79.0% and 49.5%, whereas HSA and age explained 69.7% and 41.9% of TUG and LEFS-Greek variance, respectively. CONCLUSIONS: Abductor isometric strength was the main predictor of hip-fracture patients' functionality, strongly enhancing the measured functional outcomes. Hip abductor strengthening appears to be of major clinical importance and may contribute significantly to the functional rehabilitation of hip-fractured patients.

Surgical treatment of acute type V acromioclavicular joint dislocations in professional athletes: an anatomic ligament reconstruction with synthetic implant augmentation.

BACKGROUND: Most acromioclavicular (AC) joint injuries occur in men in their third decade of life during high-speed or high-impact body contact sports. The management of acute complete AC joint dislocation is surgical. Current surgical techniques include anatomic reconstruction of the main restraints of the AC joint and aim to improve functional outcomes and to reduce the complication rate. METHODS: We present 10 cases of acute type V AC joint dislocation in professional athletes treated surgically with anatomic reconstruction of the coracoclavicular and AC ligaments and augmentation with the use of a synthetic polyester tape. The minimum follow-up of the patients was 2 years (mean, 48 months; range, 24-86 months). The postoperative functional outcome was assessed at 1 year and 2 years using the Constant-Murley, American Shoulder and Elbow Surgeons, and modified University of California-Los Angeles scoring systems. RESULTS: In all cases, the postoperative scores were significantly improved (P < .005 in all comparisons with the preoperative scores), and all patients returned to their preinjury high level of activity 6 months postoperatively. Radiographs at 1 month and 6 months revealed the maintenance of reduction. There were no complications. CONCLUSION: According to the results of our series of patients, demanding cases of acute AC joint dislocation Rockwood type V, in professional athletes, require anatomic fixation of both coracoclavicular and AC ligaments for return to sports as soon as possible and at the preinjury level of performance.

Clinical Outcomes and Complications of Cortical Button Distal Biceps Repair: A Systematic Review of the Literature.

Objectives. The purpose of the present study was to investigate the clinical outcomes and complications of the cortical button distal biceps fixation method. Material and Methods. All methods followed the PRISMA guidelines. Included studies had to describe clinical outcomes and complications after acute distal biceps repair with cortical button fixation. Eligibility criteria also included English language, more than 5 cases with minimum follow-up of 6 months, and preferably usage of at least one relevant clinical score (MEPS, ASES, and/or DASH) for final outcome. A loss of at least 30° in motion-flexion, extension, pronation, or supination-and a loss of at least 30% of strength were considered an unsatisfactory result. Results. The review identified 7 articles including 105 patients (mean age 43.6 years) with 106 acute distal biceps ruptures. Mean follow-up was 26.3 months. Functional outcome of ROM regarding flexion/extension and pronation/supination was satisfactory in 94 (89.5%) and 86 (82%) patients in respect. Averaged flexion and supination strength had been reported in 6/7 studies (97 patients) and were satisfactory in 82.4% of them. The most common complication was transient nerve palsy (14.2%). The overall reoperation rate was 4.8% (5/105 cases). Conclusion. Cortical button fixation for acute distal biceps repair is a reproducible operation with good clinical results. Most of the complications can be avoided with appropriate surgical technique.

Effects of teriparatide retreatment in a patient with ß-thalassemia major.

BACKGROUND: Bone disease is a frequent complication of ß-thalassemia major (ß-ΤΜ) and its etiology is multifactorial. Marrow expansion, chronic hypoxia, endocrine complications, and iron overload caused chiefly by chronic transfusion treatment are significant factors affecting skeletal health. Bone disease is prevalent even among patients on regular transfusions and adequate iron chelation. The life expectancy of patients with ß-thalassemia has increased during the past decade and so, nowadays, patients with thalassemia-associated bone disease (TBD) often require long-term management. There are limited data concerning their pharmacologic treatment. Bisphosphonates represent the most widely studied agents in such patients and there are no published studies about the effects of anabolic treatment. Retreatment with teriparatide has only occasionally been studied in patients with osteoporosis. CASE REPORT: We present a male adult patient with ß-ΤΜ with a history of low bone mass and multiple vertebral fractures, who required sequential treatment for his longstanding bone disease. He had exhibited considerable, albeit delayed, response to a course of teriparatide treatment for 18 months but subsequently, and while on alendronate, sustained an insufficiency fracture at the left ischiopubic ramus. A second trial of teriparatide treatment resulted in further remarkable increase in total hip and femoral neck bone mineral density. We present the patient's response to sequential treatment during an 8-year follow-up. CONCLUSION: Teriparatide could represent an alternative treatment for adults with TBD especially when long-term, sequential treatment is needed. Although there are limited data concerning retreatment, in selected cases, this might be considered.

Volumetric bone mineral density and bone geometry assessed by peripheral quantitative computed tomography in women with differentiated thyroid cancer under TSH suppression.

OBJECTIVE: TSH suppression therapy in patients with differentiated thyroid cancer (DTC) has been associated with adverse effects on areal bone mineral density (aBMD) only in postmenopausal women. The purpose of study was to examine the effect of TSH suppression therapy on skeletal integrity using peripheral quantitative computed tomography (pQCT) at the radius and tibia in pre- and postmenopausal women with DTC and controls. STUDY DESIGN AND PATIENTS: Subjects included 80 women with DTC (40 pre- and 40 postmenopausal) and 89 (29 and 60, respectively) controls. pQCT was performed at the radius and tibia, Dual-energy X-ray absorptiometry (DXA) at the hip and lumbar spine, while samples were taken for calciotropic hormones and bone markers. RESULTS: No differences were observed concerning aBMD by DXA. In premenopausal women, there were no significant differences concerning vBMD, while cortical thickness was higher at the radius in patients with DTC (P < 0·01) compared with controls. In postmenopausal women with DTC trabecular bone mineral content (BMC), area and vBMD were lower at the radius (all P < 0·05), while at the tibia trabecular BMC and vBMD were lower at the mixed transition zone (14% from the distal end, P < 0·05) compared with controls. Cortical thickness was lower at the radius (P < 0·01) in postmenopausal patients compared with controls. Serum CTX was higher in postmenopausal women with DCT (P < 0·01), while in premenopausal patients, parathyroid hormone (PTH) was lower (P = 0·01) compared with controls. CONCLUSIONS: TSH suppression therapy is associated with higher bone resorption only in postmenopausal women; this adversely affects trabecular and cortical bone properties especially at nonweight-bearing sites such as the radius.
