INTRODUCTION: Traumatic spinal cord injury (SCI) leads to increased intraspinal pressure that can be prevented by durotomy and duroplasty. The aim of the study was to evaluate fibrosis and neural damage in a porcine model of SCI after duroplasty and application of hyaluronic acid (HA) in the tissue cavity. MATERIALS AND METHODS: Experimental study. We created a porcine SCI model by durotomy and spinal cord hemisection of a cervical segment (1 cm). Six pigs (Sus scrofa domestica) were used to evaluate three surgical scenarios: (1) control injury with dural reparative microsurgery, (2) duroplasty using bovine pericardium (BPD), and (3) previous method plus HA applied at the lesion...

INTRODUCTION: Controversy exists in the literature about the best treatment for type III acromioclavicular dislocations. The aim of this study is to compare functional results between surgical and conservative treatment in type III acromioclavicular joint dislocations. MATERIAL AND METHOD: We retrospectively evaluated the records of 30 patients from our area with acute type III acromioclavicular dislocations that were treated from January 1st, 2016 to December 31st, 2020...

BACKGROUND: The role of prophylactic pinning of the contralateral hip in unilateral SCFE is well established in patients with risk factors for developing contralateral slip. The effect of prophylactic pinning on the growth and morphology of the hip is not well documented in the literature. We aimed to study the effect of prophylactic pinning on the residual growth and morphology of the proximal femur. MATERIALS & METHODS: The institutional database was searched for all unilateral SCFE cases for the period 2011 to 2020...

Introduction Bone defects are one of the main limitations in orthopedic surgery and traumatology. For this reason, multiple bone replacement systems have been developed, either by prosthetic implant or by substitution with osteoforming substances, whose limitations are their survival and lack of structurality, respectively. The objective of this work is the generation of a new material for the creation of biologically active structures that have sufficient tensile strength to maintain the structure during remodeling...

Introduction The total knee arthroplasty (TKA) has been shown to be a successful and cost-benefit procedure in terms of pain improvement in patient with symptomatic knee osteoarthritis. However, almost a 20% of the patients are not satisfied with the result of the surgery. Material and method We have carried out a transversal unicentric cases controls study with clinical cases of the own hospital, obtained by a clinical records revision. A total of 160 patients with a TKA with at least 1 year of follow-up were selected...

Developmental dysplasia of the hip is the cause of approximately one third of secondary coxarthrosis. Anatomy alterations make it difficult to place a total hip prosthesis in its anatomical position and for it to be stable in the long term; there are several techniques to achieve this goal. In the present work, we used autograft of the femoral head (shelf graft or reinforced roof), to improve the coverage of the acetabular component with favourable results. Materials ad methods Sixteen cases were included in 14 patients with a diagnosis of developmental dysplasia of the hip (13 women and one man), the mean age was 44...

BACKGROUND: Postoperative outcome measurement typically relies on postoperative radiological results and clinical-functional scales; however, there is a growing interest in considering patient satisfaction (including subjective aspects) as part of the success of forefoot surgery. OBJECTIVE: To determine whether showing a preoperative photograph improves satisfaction in postoperative forefoot surgery patients. MATERIAL AND METHODS: An observational, cross-sectional, analytical study was conducted in the foot and ankle unit of our center...

INTRODUCTION: The treatment of rhizarthrosis using trapeziometacarpal prostheses (TMP) is increasing. Complications may lead to loss of the implant and result in salvage surgery. Our aim was to assess major complications with the use of some TMP models and their rescue. MATERIAL AND METHOD: Retrospective study on TMP implanted between 2006 and 2021. Models studied: Arpe®, Elektra®, Ivory®, Maïa®, Isis® and Touch®. Demographic data were assessed, implant placement by radiographic study, technical data, complications, salvage surgeries and final survival...

INTRODUCTION: Spinal instrumentation-related infections (SIRI) are one of the main causes of post-surgical complication and comorbidity. Our objective was to describe the clinical and microbiological characteristics, treatment and prognosis of these infections. MATERIAL AND METHODS: We conducted a retrospective study in our institution (2011-2018) including adult patients undergoing spinal instrumentation who met the diagnostic criteria for confirmed infection. Superficial surgical wound and deep intraoperative samples were processed for microbiological culture...

INTRODUCTION: The main complication of percutaneous iliosacral screw fixation is implant malposition, which can lead to vascular and nerve damage. The anatomical variability of the sacrum can make screw insertion difficult under fluoroscopic guidance. Among the methods described to improve the accuracy of this technique, stands out the use of computed tomography (CT). The aim of this study is to compare the results of iliosacral screw insertion with fluoroscopy or CT navigation. METHODOLOGY: Retrospective cohort study of 66 iliosacral screws in 56 patients during 11 years...

OBJECTIVE: To analyze the efficacy and safety after the application of platelet-rich-plasma (PRP) as an adjuvant in arthroscopic rotator cuff repairs. MATERIAL AND METHODS: A bibliographic search of the literature of prospective studies with level of evidence one or two was carried out from January 2004 to December 2021, including studies that compare the functional and re-tear results after arthroscopic cuff repair rotator with or without PRP. RESULTS: A total of 281 articles were identified, of which 14 met the inclusion criteria...

BACKGROUND AND OBJECTIVES: The purpose of this study is to analyze the indications, complications, survivorship and clinical/functional outcome of metaphyseal sleeves as a treatment option in revision total knee arthroplasty. MATERIAL AND METHOD: A systematic review was made following the PRISMA recommendations on the use of metaphyseal sleeves for revision total knee arthroplasty. We included prospective and retrospective studies published in the last 10 years looking at implant survivorship, clinical and functional outcome with a minimum follow-up of 2 years...

BACKGROUND: The COVID-19 pandemic may have adversely affected the early diagnosis of skin cancer. OBJECTIVE: To compare epidemiological, clinical and histopathological characteristics in patients undergoing cutaneous squamous cell carcinoma (SCC) surgery before and after the beginning of the pandemic. MATERIAL & METHODS: We conducted a cross-sectional study including two case series: 1) patients operated on for SCC in the year after the first state of alarm in Spain (15 March 2020), and 2) patients with SCC operated on in the previous year...

BACKGROUND: Hereditary haemorrhagic telangiectasia (HHT) is characterized by the presence of telangiectases and larger arteriovenous malformations in different organs. Mucocutaneous telangiectases can bleed and become an aesthetic concern, impairing quality of life (QoL). However, the best treatment approach has not been defined yet. OBJECTIVE: To evaluate the efficacy and safety of dual wavelength sequential 595/1064nm laser (DWSL) compared to 1064nm laser (Nd:YAG) alone...
