RESUMEN

Transient osteoporosis (TO) or bone marrow edema syndrome (BMES) is a self-limited clinical condition, which affects middle-aged men and women. It can be treated with miscellaneous conservative and surgical measures, which are analyzed in this systematic review. INTRODUCTION: BMES/TO is a transient clinical entity, which can be treated with various therapeutic modalities. The aim of our study was to assess the efficacy of different therapeutic options for the alleviation of pain and reduction of bone marrow edema (BME) in patients with BMES/TO, as well as to propose a therapeutic algorithm. METHODS: PubMed, Scopus, Cochrane, and Google Scholar were searched. Eligibility and extraction of studies were conducted by two authors. Methodological quality assessment was carried out with the modified Delphi technique, Methodological Index for Non-Randomized Studies (MINORS) criteria, and Cochrane Collaboration's risk of bias tool. Outcomes that were compared were time of pain resolution, VAS pain scores, and BME regression on magnetic resonance imaging (MRI). RESULTS: A total of 36 articles (880 patients) were included. Bisphosphonates had higher efficiency in less than 1-month outcomes on pain resolution compared with core decompression (CD), while iloprost was more efficient at 1-3 months compared with bisphosphonates and CD. At 3-6 months, all three of the aforementioned showed equal results on pain resolution, and at a period of 6-12 months, CD and extracorporeal shockwave therapy (ESWT) showed excellent results followed by bisphosphonates and the conservative group (CG) consisting of non-steroidal anti-inflammatory drugs (NSAIDs) and/or analgesics and/or restricted weight bearing. On MRI at 1-3 months, bisphosphonates, iloprost, and CD had relatively the same outcomes on BME resolution, with the least promising being the CG. At 3-6 months, CD seemed to have achieved the best results on the resolution of BME, followed by ESWT, CG, and bisphosphonates group. At 6-12 months, ESWT had the best outcomes compared with the conservative, bisphosphonates, and iloprost groups. CONCLUSION: BMES/TO has been treated with many non-standardized measures due to the low number of highly reliable studies. Current literature shows promising results with regard to the reduction of the clinical course of BMES/TO, but further large multicenter randomized controlled trials, as well as standardized radiological and clinical scores, are warranted to acquire evidence-based recommendations on the therapeutic algorithm.

RESUMEN

INTRODUCTION: Fragility fractures around the proximal end of the femur have increased in recent years due to an aging population, adding to the pressure on national health care systems and to hospital expenses. Peri-trochanteric fractures have historically been treated successfully with anatomic intramedullary nails, giving stable fixation in order to allow early for mobilisation of these frail patients. Some of these nails allow a second (anti-rotational) screw through the nail into the femoral head. We assessed the use of this additional screw in terms of quality of reduction, post-operative mobilization and complications. MATERIALS & METHODS: All patients who were treated in the same hospital for peri-trochanteric fracture between January 2017 and December 2019 were included in the study. The patients were randomly assigned into group A, where the treatment included intramedullary nailing using one femoral hip screw, and group B, where the treatment additionally included a second anti-rotational screw. The patients were followed up clinically and radiologically, for at least 3 months post-operatively. Demographic and operative data were collected alongside radiographic and clinical data. RESULTS: A total of 118 patients with an average age of 82.7 years were included in the study after exclusion criteria was applied. There were no statistically significant differences between the two groups regarding the ASA grade, Nottingham Hip fracture score, Koval score, Mental score, operation time, transfusion requirements, and operative radiation dose and time (p > 0.05). In group A, more complications were observed (p < 0.05). The radiographic measurements were statistically significantly different. CART analysis revealed that the use of a single screw in the femoral head for the subgroup of the unstable peri-trochanteric fractures (Jensen Type 4-5 - AO31A2.2 and above), has a tendency toward developing more post-operative complications, though this was not statistically significant. CONCLUSION: The use of an additional anti-rotational screw for unstable peri-trochanteric fractures (Jensen Type 4-5 and AO 31A2.2 and above) could prevent complications such as varus collapse and cut-out.

RESUMEN

PURPOSE: The purpose of this study was to systematically review case reports and case series about meniscal ossicle, to summarize existing evidence. Specifically, to identify the etiology, demographic characteristics, localization, clinical features, diagnostic procedures and treatment options of this rare entity. Although, case reports/ series are of low level of evidence, a systematic review of such studies can provide and help us to gain a better understanding and awareness of meniscal ossicle. METHODS: Two authors searched three online databases (MEDLINE, SCOPUS and GOOGLE SCHOLAR) from inception until March 2020 for the literature on meniscal ossicle. Inclusion criteria included case series, case reports and case-based reviews, available in full-text version, in English and that concern humans. Reports published in languages other than English were excluded, as well as articles with no electronic full text availability. Case reports using the term "meniscal ossicle" to describe an acute avulsion fracture of the tibial root of the meniscus, were also excluded. RESULTS: Of 453 initial studies, 38 studies satisfied inclusion criteria. In total 169 patients were included of whom 107 (63%) were males and 62 (37%) were females. Mean age was 44 years (range 12-87). According to Magnetic resonance imaging findings, in 144 knees (86%) the ossicle was localized at the posterior root or horn of the medial meniscus. 60% of the patients had a history of trauma. The predominant symptom in 87% of patients was knee pain. In all patients was detected an intra-articular density structure in computed radiography. 76% had associated meniscal tear, 61% had intraarticular cartilage loss, 34% meniscal extrusion and 28% anterior cruciate ligament injury. Treatment modalities included conservative regimen in 40 patients, while 59 patients underwent surgical excision. CONCLUSION: The most possible etiology of meniscal ossicle is posttraumatic heterotopic ossification and small occult bony avulsion fracture. It is commonly observed in individuals complaining about knee pain with history of antecedent trauma. The presence of a meniscal ossicle should alert the physician to the high likelihood of the patient having an associated meniscal tear, articular cartilage loss, ACL injury or meniscal extrusion. Along with the meniscal ossicle, the associated meniscal tear should be treated as well.

RESUMEN

BACKGROUND Osteoporosis affects millions of postmenopausal women worldwide. Invariant natural killer T cells (iNKT) are important cells for bone homeostasis. The sim of this study was to investigate the contribution of invariant natural killer T cells (iNKT) in the increased receptor activator of the nuclear factor-kappaB ligand (RANKL) pool and bone resorption, a characteristic of patients with osteoporosis. MATERIAL AND METHODS Whole blood was collected from 79 female patients. The dual energy x-absorptiometry scan was performed in all patients, and the T-score was calculated in order to classify our patients according to the World Human Organization (WHO) criteria for diagnosis and classification of osteoporosis. Eleven patients had a T-score -2.5 and were included in the osteoporosis group. We performed alpha-galactosylceramide activation of iNKT cells in vitro. Surface RANKL expression was detected by multicolor flow cytometry in naive and activated lymphocytes. Beta-Crosslaps (ß-CTx) levels were measured in whole blood plasma by ELISA (enzyme-linked immunosorbent assay). RESULTS Although iNKT cells were not clonally expanded in patients with osteoporosis, iNKT cells from osteoporotic patients overexpressed RANKL compared to ND and osteopenic patients. This is a distinctive feature of iNKT cells and is not seen in conventional T-lymphocytes. RANKL expression in iNKT cells was not related to ß-CTx levels in the blood. Finally, iNKT cell activation by the prototypal glycolipid ligand alpha-galactosylceramide increased by 8 times their RANKL expression. CONCLUSIONS In patients with osteoporosis, iNKT cells specifically overexpress RANKL, a cytokine that regulates osteoclast activity. It seems that iNKT cells have a long-standing effect of on the bone physiology, which plays an important role in the bone loss of patients with osteoporosis.

RESUMEN

BACKGROUND: Osteochondromas or exostoses are the most common benign tumors of the bones, which appear during the growth period. The involvement of lower extremities is common, particularly in metaphyseal structures of the femur and humerus and around the knee joint. However, the incidence of the development of the tumor at the proximal fibula is rare. The most common signs and symptoms of the disease are pain, pulsatile mass, limb swelling, neurologic sequelae, bursa formation with subsequent bursitis, and impairment of the developmental growth. Vascular complications are rare, yet osteochondromas can cause catastrophic arterial complications threatening the life of the patient if they occur and can include vessel perforation and thrombosis, arterial thromboembolic events, and pseudoaneurysm formation. METHODS: We report a case of a 24-year-old male patient presenting with tibioperoneal arterial trunk entrapment caused by a massive osteochondroma derived from the proximal fibula. A combined vascular-orthopedic approach was initiated with the excision of the tumor, in which the neurovascular structures (tibial nerve, popliteal artery and vein, anterior tibial artery, and tibioperoneal trunk) were carefully recognized and protected. RESULTS: The postoperative course of the patient was uneventful. CONCLUSIONS: High clinical suspicion of a vascular complication should be raised by physicians when investigating a young patient with a suspected osseous tumor in the popliteal fossa and symptomatology of concurrent peripheral arterial disease. Prompt surgical management is crucial for the salvage of the affected limb in cases of arterial involvement. Furthermore, quick surgical exposure of the mass and regular postoperative follow-up check minimizes the risk of irreparable impairments and tumor recurrence.

RESUMEN

BACKGROUND: Tranexamic acid (TXA) is widely used in the orthopedic field and particularly in total knee arthroplasty (TKA). Its efficacy and safety in reducing the blood loss in TKA have been well-documented in the current literature. Little data regarding TKA without tourniquet and TXA exist. Our aim is to compare three different dosages of intravenous (IV) TXA in TKA without tourniquet. MATERIALS AND METHODS: A total of 180 patients undergoing TKA for knee osteoarthritis were stratified in three equal groups. All surgeries were performed under spinal anesthesia, without tourniquet. Group A (60 patients) received 15 mg/kg of IV TXA given on induction, Group B (60 patients) received an additional dose of IV TXA (15 mg/kg) 3 h after incision and Group C (60 patients) received an additional (third) dose 3 h later (15 mg/kg). The measured outcomes were the change in hemoglobin (Hb) from pre-operatively to post-operatively, the amount of blood transfusion given (units), the functional and quality of life (QoL) and pain assessment based on their corresponding scoring system. RESULTS: Calculated blood loss, Hb decrease and transfusion rate were significantly lower in Group C (p value < 0.05). Additionally, patients that had been included in the three-dosage group benefited much more in terms of faster rehabilitation, better QoL, decreased post-operative pain, with no increase in complications. CONCLUSION: According to our results, three doses of IV TXA have effectively and safely reduced blood loss and the need of allogeneic blood transfusion in patients undergoing TKA without tourniquet, with additional patients-related benefits. LEVEL OF EVIDENCE: II.

RESUMEN

BACKGROUND: The purpose of this study was the translation, cross-cultural adaptation and validation of the Achilles Tendon Total Rupture Score (ATRS) in Greek population. METHODS: The translation and cross-cultural adaptation of the original version of ATRS in Greek language was performed according to the methodology described by Beaton et al. Validation and test-retest reliability were evaluated in forty-six patients, treated surgically for acute Achilles tendon rupture. Validity was evaluated by correlation of total and all subscale scores of Greek version of Manchester Foot Pain and Disability Index (MFPDI). Test-retest reliability evaluated with interclass correlation coefficient and Crombach's α coefficient was used for internal consistency. RESULTS: The internal consistency (α=0.96) and test-retest reliability (ICC=0.97) were excellent. There were no ceiling and floor effects during test-retest assessment. The Greek version of ATRS showed strong correlation with all subscales and overall score of MFPDI (pain subscale: R=-0.954, p<0.01, function subscale: R=-0.811, p<0.01, appearance subscale: R=-0.763, p<0.01, overall: R=-0.914, p<0.01). CONCLUSIONS: Greek version of ATRS was successfully adapted in Greek population and it appears to be a valid and reliable instrument to evaluate outcomes in Greek speaking patients after Achilles tendon rupture. LEVEL OF EVIDENCE: Level III.

RESUMEN

INTRODUCTION: It is still unknown whether the creation of blood-free surfaces by the use of tourniquet during total knee arthroplasty (TKA) has an influence on cement penetration and on implant fixation. The aim of this study is to evaluate the cement mantle under tibial component and the occurrence of progressive radiolucent lines (RLLs) according to the use of tourniquet in primary TKA. MATERIALS AND METHODS: Fifty patients undergone TKA without the use of tourniquet (group 1) were well matched regarding baseline characteristics with 50 TKAs with the use of tourniquet (group 2). Patients were followed up prospectively. Cement mantle thickness was measured using immediate postoperative X-rays, and the occurrence of progressive radiolucency was finally evaluated in 3-year follow-up. New Knee Society Score (KSS) was used to compare clinical outcome between groups. RESULTS: Mean cement mantle thickness was 9.27 ± 1.86 mm in group 1 versus 10.49 ± 2.31 mm in group 2 (p = 0.005). Mean cumulated width of RLLs in anterioposterior (AP) view was 7.74 ± 6.68 mm in group 1 versus 3.48 ± 4.69 mm in group 2 (p < 0.001). The percentage of RLLs in AP view was related to the cumulated cement mantle thickness in the same view (r = - 0.218, p < 0.05). There was no significant difference between groups at the final follow-up in terms of ROM and new KSS. CONCLUSION: Our results suggest that the use of tourniquet increased the cement mantle thickness under tibial implant and had an influence on the occurrence of RLLs in cement-bone interface, which is related to implant survivorship, with this implant design.

RESUMEN

In this article, two cases of ulnar nerve neuropathy in Guyon's canal caused by a ganglion cyst are reported. A review of the literature found 73 cases reported in 35 articles of ulnar neuropathy at the wrist secondary to a ganglion cyst. We investigated the pathogenesis of ganglion cysts, which are separated as extraneural and intraneural. At this anatomical area, there are a variety of clinical factors that can also lead to ulnar nerve compression such us trauma, fracture of the hamate's hook, arterial thrombosis, tumors and other anatomical variations. The symptoms may include weakness, paresthesia, numbness and atrophy of hypothenar muscles. Except the careful clinical assessment, magnetic resonance imaging, ultrasound and electrophysiological control are useful tools regarding our differential diagnosis. The treatment of this clinical condition is surgical. We consider that instant surgical decompression is of the essence and enables postoperatively total recovery. LEVEL OF EVIDENCE: Level III.

RESUMEN

BACKGROUND The Nottingham Hip Fracture Score (NHFS) is validated as a predictive mortality tool in patients with hip fracture. However, it has not been modified or validated widely other than in the UK NHS health systems. MATERIAL AND METHODS We assessed the predictive capability of the NHFS for 30-day mortality after surgery for hip fracture in the Greek population and then compared the original model to a modified one. We applied the NHFS to the Greek population and created a modified model of the NHFS by including the New Mobility Score (NMS) (Parker and Palmer, 1993) to the evaluated parameters and excluding the parameter of institution. We ran a prospective study over a period of 3 years in our institution, collecting full data from 349 patients. All data were analyzed using SPSS, version 20. RESULTS From all 349 patients, with a mean age of 80.82 years, only 85 (24.4%) were men. All patients were followed up for at least 30 days and the NHFS and modified NHFS prediction were compared with the mortality rate of patients. The area under the ROC curve for both models suggested acceptable accuracy (original NHFS 0.83, modified NHFS 0.84). Calibration was acceptable for both models (Hosmer-Lemeshow p=0.31 and 0.11, respectively). CONCLUSIONS Both the original and the modified NHFS were significant predictors of 30-day mortality. A higher-power study might be able to show superiority of the modified one for the Greek population in the future.

RESUMEN

Radio-opaque formations behind the spinous processes of the cervical spine are really rare. They were described in 1929 for the first time. Sesamoid ossicles are found close to a bone or a joint and are usually small. Some sesamoids form part of normal human anatomy, while others are normal anatomical variants. We report a case of a 73-year-old Caucasian male who visited the outpatient clinic complaining about chronic cervical pain. An oblong sesamoid accidentally discovered during routine anteroposterior (AP) and lateral x-ray, within the nuchal ligament (NL) at the C3-C6 spinous processes level. A cervical MRI scan was performed and the result showed 'fabella nuchae'. This type of sesamoids are rarely symptomatic, but it should be differentially diagnosed anyway. We review its morphology, the mechanical factors of the region acting throughout life and last, but not least, the differential diagnosis.

RESUMEN

BACKGROUND: Use of tranexamic acid (TXA) is effective and safe in reducing the blood loss in total knee arthroplasty (TKR) performed using a tourniquet, but, data in TKR performed without tourniquet are limited, and there is no study comparing the topical (T) with intravenous (IV) TXA administration. Our aim was to compare the topical (T) with intravenous (IV) TXA administration in TKR performed without tourniquet. MATERIAL AND METHODS: A total of 120 patients undergoing unilateral TKR for knee osteoarthritis were included in a prospective randomized study. Operations were performed under spinal anesthesia, no tourniquet was used, and the postoperative regime was the same for all patients. Patients were divided into 3 groups; in group C (control), 40 patients received no TXA, in group IV, 40 patients received 1 g of TXA intravenously, and in group L, 1 g of TXA was applied locally to 40 patients. The primary outcome measures included the calculated blood loss, the transfusion rate, and quantity of allogeneic blood units, whereas secondary outcome measures were complications. RESULTS: There was no statistically significant difference in patient's demographics and perioperative results. Calculated blood loss, allogeneic blood transfusion rate, and quantity in group C were significantly higher compared with those of TXA groups (P < .001). There was no significant difference in complications rate between the 3 groups. CONCLUSIONS: According to the results of this study, IV or T administration of 1-g TXA significantly reduced the blood loss and the need for allogeneic blood transfusion in patients undergoing TKR without a tourniquet (with no significant difference between the 2 routes of administration).

RESUMEN

BACKGROUND: Patient-reported outcomes require validation in a particular language and culture before administration for clinical use. MATERIALS AND METHODS: A systematic translation of the IKDC Subjective Knee Form was initially tested in 30 patients with various knee pathologies to develop the first Greek version (IKDC/SKF-GR). It was then administered to another 80 patients. The test-retest reliability (n = 35) and internal consistency (n = 80) were examined. Construct validity was tested by correlating the IKDC/SKF-GR with the SF-36 subscales (n = 80) and content validity by measuring floor/ceiling effects. Responsiveness was measured in patients with meniscus pathology (n = 24). RESULTS: Patients filled the form without omissions/questions regarding the phrasing of items. Internal consistency was good (Cronbach's α = 0.87) and test-retest reliability very good (ICC2,1 = 0.95, SEM = 4.4 and SDC = 12.2). Correlations with the SF-36 subscales confirmed its construct validity. No floor/ceiling effects were recorded. The effect size was large (ES = 1.26). CONCLUSIONS: The IKDC/SKF-GR has comparable measurement properties to the original form. LEVEL OF EVIDENCE: Level II.

RESUMEN

Total knee replacement (TKR) is a successful procedure for pain relief and functional restoration in patients with advanced osteoarthritis. The number of TKRs is increasing, and this has led to an increase in revision surgeries. The key to long-term success in both primary and revision TKR is stability, as well as adequate and stable fixation between components and underlying bone. In the vast majority of primary TKRs and in some revision cases, a posterior cruciate retaining or a posterior cruciate substituting device can be used. In some primary cases with severe deformity or ligamentous instability and in most of the revision cases, a more constrained implant is required. The purpose of this paper is to review the literature concerning the use of condylar constrained knee (CCK) and rotating hinge (RH) implants in primary and revision cases focusing on the indications and results. According to this review, although excellent and very good results have been reported, there are limitations of the existing literature concerning the indications for the use of constrained implants, the absence of long-term results, and the limited comparative studies.

RESUMEN

BACKGROUND: Vitamin D plays an important role in bone mineralization, remodeling, and maintenance and therefore its deficiency may be implicated in the pathogenesis of osteoarthritis (OA). Vitamin D status was evaluated in patients with knee or hip OA scheduled for joint replacement. The impact of anthropometric parameters such as gender, age, and body mass index on vitamin D levels was also examined. The study was conducted in a Mediterranean country (Greece). MATERIALS AND METHODS: We included 164 patients with knee or hip OA scheduled for joint replacement in this study. Serum levels of 25-hydroxyvitamin D (vitamin D) were measured in routine blood samples taken from the patients at their pre-admission visit, a week before the operation, using radioimmunoassay. RESULTS: The majority of patients were vitamin D deficient (81.7 %); 15.2 % of them were vitamin D insufficient (hypovitaminosis). Only 3 % of patients were vitamin D sufficient. There was a significantly positive association between vitamin D levels and male gender. CONCLUSION: These findings indicate a large percentage of vitamin D deficient patients with knee or hip OA, which is unexpected considering the high annual insolation in northern Greece. Many other possible predisposing factors for OA should be taken into consideration. Whether treatment with vitamin D supplements may provide beneficial effects to these patients and the stage of disease in which this treatment should commence remains an issue for further scientific investigation. LEVEL OF EVIDENCE: Level IV.

RESUMEN

Osteomyelitis is a bone infection by micro-organisms. Despite advances in antibiotics and operative techniques, osteomyelitis remains an orthopaedic challenge and expensive to treat. Antimicrobial therapy is adequate for the treatment of most cases of acute osteomyelitis of any type, provided that diagnosis is made early. The treatment of chronic osteomyelitis is operative followed by adjunctive antibiotic therapy. Apart from surgical debridement and systemic antibiotic treatment, local antibiotic treatment by using various antibiotic delivery vehicles is a preferred method by most surgeons. Antibiotic-loaded bone cement (polymethylmethacrylate, PMMA) is the most widely used material and represents the current standard as an antibiotic delivery vehicle in orthopaedic surgery. Despite that, there are some disadvantages or concerns about the use of antibiotic-loaded PMMA that have led to the use of bioabsorbable or biodegradable material. Although the number of clinical studies is small, it seems that antibiotic-loaded hydroxyapatite and calcium sulfate are safe methods for local antibiotic delivery. They deliver great amounts of antibiotics locally with serum concentrations in safe margins, they obliterate the dead space, and aid in bone repair, while there is no need for a second operation for their removal. The purpose of this article is to review the recent literature concerning osteomyelitis and local antibiotic treatment with special reference to bone graft substitutes as vehicles for local antibiotic delivery.

RESUMEN

Osteomyelitis is a bone infection accompanied by inflammatory process, which can lead to destruction and bone necrosis. It is difficult to manage, and there are no commonly accepted guidelines. While most acute bone infections are usually successfully treated with intravenous antibiotics, chronic infections and infections in the presence of foreign materials usually require operative treatment with debridement, removal of metals, intravenous antibiotics, and very often local antibiotics. The aim of this study was to perform a systematic review of the existing literature concerning the use of bone grafts as carriers for local antibiotic delivery for the treatment and prevention of bone infections. According to the literature, antibiotic-loaded autologous bone grafts for the treatment of infected tibial nonunion is a good option (Grade-B recommendations). Although there are several studies concerning the use of antibiotic-loaded allogenic bone grafts in infected joint arthroplasty revisions, there is a lack of comparative studies (Grade-C recommendations). Studies concerning spinal fusion and spondylodiscitis are limited (Grade-I recommendations).

RESUMEN

The management of complex and severe lower-extremity injuries is challenging for the orthopedic surgeon. When the primary or secondary closure of the defect is not feasible, complex procedures with graft (split-thickness or full-thickness) or flap (pedicled or free) are required. These procedures are performed by specialized plastic surgeons and are at high risk for adverse effects, even high morbidity among both the donor and acceptor sites. Furthermore, split-thickness skin grafts (STSGs) often lead to unsatisfactory results in terms of mechanical stability, flexibility, and aesthetics due to the lack of underlying dermal tissue. Consequently, dermal substitutes, such as MatriDerm (MedSkin Solutions Dr Suwelack AG, Billerbeck, Germany), have been proposed and further developed as a treatment option addressing the management of full-thickness wound defects in conjunction with STSGs. We aimed to present a case of post-traumatic full-thickness wound defect of the left foot after traumatic amputation of the digits that was treated with MatriDerm combined with autologous STSG. In addition, we performed a systematic review of the literature to delineate the efficacy of the use of MatriDerm combined with STSGs in orthopedic cases exclusively.
