Tratamiento del choque femoroacetabular mediante miniabordaje anterior. Resultados a corto plazo

El tratamiento quirúrgico del choque femoroacetabular (CFA) es un práctica clínica cada vez más frecuente en nuestra especialidad. Objetivo. Analizar los resultados clínicos y radiológicos de una primera serie de pacientes diagnosticados de CFA intervenidos mediante miniabordaje anterior. Material y métodos. Estudio prospectivo de 30 pacientes con una edad media de 36,2 años y un seguimiento mínimo de 12 meses. La valoración clínica se ha realizado mediante las escalas SF-36, WOMAC y NAHS. Evaluamos la corrección radiológica de la deformidad y la progresión o no del grado de coxartrosis. Resultados. Se obtuvo una corrección adecuada de la deformidad en el 93% de los casos, 27 de los 30 pacientes presentaron una mejoría clínica significativa en los test realizados. La complicación más frecuente fue la meralgia parestésica del femorocutáneo (5 casos), 1 paciente precisó de sustitución protésica por evolución del grado de coxartrosis. Conclusiones. El tratamiento del CFA mediante mini abordaje anterior es un procedimiento seguro y reproducible. Permite la corrección de las anormalidades anatómicas y la obtención de resultados clínicos satisfactorios en una cohorte de pacientes jóvenes.Surgical treatment of femoroacetabular impingement (FAI) is an increasingly common clinical practice in our speciality. Aim. To analyze the clinical and radiological results of a first series of patients diagnosed with a FAI treated with anterior mini-open approach. Material and methods. Prospective study of 30 patients with a mean age of 36.2 years with a minimum follow-up of 12 months was made. Clinical assessment was performed using the SF-36, WOMAC and NAHS scales. We evaluate the correction of the radiologic deformity and progression of the osteoarthritis grade. Results. An adequate correction of the deformity in 93% of cases was obtained, 27 of the 30 patients showed significant clinical improvement in all tests performed. The most common complication was meralgia paresthesia of the femoro-cutaneous nerve (5 cases), 1 patient required prosthetic replacement for progression of the osteoarthritis grade. Conclusions. FAI treatment by mini-open approach is a safe and reproducible procedure. This technique allows correction of anatomical abnormalities and obtains satisfactory clinical outcomes in a cohort of young patients

Case Report Skin Abscess due to Serratia marcescens in an Immunocompetent Patient after Receiving a Tattoo

The incidence of skin infections caused by Serratia marcescens is extremely low and such infections are typically observed in immunocompromised patients. The clinical manifestations of these infections include cellulitis, abscesses, fluctuant nodules, or granulomatous lesions. Infections caused by S. marcescens are very difficult to treat due to their resistance to many antibiotics, which often leads to specific and prolonged treatment. Infections after receiving a tattoo are very rare and are caused by unhygienic conditions or the inexperience of the tattooist. In this paper we present the case of a 32-year-old male with no comorbidity, who presented an abscess caused by S. marcescens in a area that was tattooed one month earlier. The case was resolved with surgery and antimicrobial therapy that was based on the antibiogram. To our knowledge, this is the first reported case of a S. marcescens skin infection following a tattoo, in the absence of immunosuppression

Infección protésica de cadera : recambio en dos tiempos en una serie de 50 casos

Chronic infection in hip replacement is an important complication with a complex treatment, that is solved by adequate antibiotic therapy together with single-stage exchange or two-stage exchange. We present a descriptiveand retrospective study of a series of 50 consecutive patients operated on in our center with a diagnosis of chronic infection of the hip prosthesis between 2007 and 2018 with a two-stage exchange.At a mean follow-up of 52 months, the overall implant survival was 89%, with a 91% infection cure rate. The most frequent microorganism isolated was Staphylococcus epidermidis. The mean score achieved on the HHS was 82,4 points and 1.67 points on the visual analogue scale. We obtained better functional results (p=0,021) in those patients who had a preformed antibiotic-loaded spacer in the first surgical stage.As complications, we recorded four cases of prosthetic reinfection (8,7%), three cases of dislocation (6,5%), and one case of postsurgical hematoma (4,6%).No case of neurovascular injury or component loosening was recorded.According to the showed results, we consider that two-stage revision procedure, although it is a demanding surgery, is an effective method for the treatment of periprosthetic hip infection, with high implant survival and erradication of the infection

Vástagos monobloque de recubrimiento completo en cirugía de revisión femoral. Resultados a largo plazo de 80 casos.

Bone stock lost and anatomical changes in the proximal femur make femoral revision surgery a complex procedure where the implant chooses will be essential. With the aim of evaluating the clinical and radiological results of the fully coated monoblock stems, we retrospectively studied 80 consecutive cases of femoral revision surgery operated by our hip team. The mean follow-up was 8.6 years. The average score on the Harris Hip Score was 81,2 points. We achieved better results in patients with less bone defects (Paprosky I, II and IIIA) in contrast to those with Paprosky type IIIB defects (p=0.005), in patients with a single previous surgery (p=0.031), in patients under 65 years (p=0.009) and in those who did not suffer complications (p=0.024). The survival rate was 96.1% at 10 years if we consider as failure the removal of the stem due to aseptic loosening and 89.9% if we consider revision of the stem as a failure due to any cause. After the results obtained, we think that fully coated stems provide a solid and stable fixation in femoral revision surgery. However, worst results obtained in patients with bigger bone defects make other options to be considered

Choque extraarticular de cadera secundario a consolidación viciosa tras fractura-avulsión de la espina ilíaca antero inferior : a propósito de un caso

The anterior inferior iliac spine (AIIS) avulsion fractures are uncommon, caused by a sudden contraction of the rectus femoris muscle with hyperextension of the hip and knee flexion. We present the clinical case of a 32-year-old mansuffering from pain in his right hip for several years with a history of a AIIS avulsion fracture in his childhood. He presented pain with flexion and internal rotation of the right hip. Physical examination and imaging tests revealed an extra-articular hip impingement secondary to a malunited fracture of AIIS. The patient underwent surgery performing AIIS osteoplasty and excision of the ossification by an anterior mini-open approach. After surgery he was able to re-join sports activity. Malunited fracture of AIIS can cause an extra-articular hip impingement in young sports patients. The treatment by surgical excision of the hypertrophic spine through an anterior mini-open approach allows the correction of the deformity and an early reincorporation to sports activities
