Análisis de los resultados y los factores adversos de la reparación artroscópica de las lesiones del subescapular de origen degenerativo / Analysis of the results and adverse factors of arthroscopic repair of degenerative subscapular lesions

Objetivo: Realizar una revisión de roturas del subescapular (SBE) de origen degenerativo tras su reparación por artroscopia y evaluar si los resultados son equiparables en términos de dolor y función a los de pacientes más jóvenes con roturas traumáticas. Material y método: Se han revisado de forma retrospectiva los datos de 80 roturas de SBE de las 660 roturas de manguito rotador intervenidas por el mismo equipo de cirujanos desde junio de 2008 hasta junio de 2018. Se recogieron los datos clínicos de los pacientes intervenidos: edad, género, lateralidad, demora de intervención, patologías asociadas, localización del dolor, valor de la escala visual analógica (EVA) y del test de Constant-Murley (TCM); se han recogido también los datos quirúrgicos: tipo y tamaño de lesión, lesión asociada del bíceps y gesto quirúrgico asociado, estenosis coracoidea y gesto quirúrgico asociado y número y tipo de anclajes empleados. Se realizó estudio estadístico con prueba de regresión lineal múltiple, pruebas paramétricas (t de Student o ANOVA) y pruebas no paramétricas. Resultados: De 80 pacientes, 36 fueron mujeres (45%) y 44, hombres (55%); media de edad de 61años (rango 47 a 81); demora media de la cirugía de 3,5meses (rango 1 a 6); hombro derecho afecto en 46 casos (57,5%), el izquierdo en 34 (42,5%); 22 (27,5%) fueron lesiones aisladas, 58 (72,5%), asociadas a rotura del supraespinoso (SPE). La mejoría media fue de 5,0 puntos en términos de la EVA y de 39,9 puntos de media en el TCM. Índice de nueva rotura, 1,25%. Factores adversos: tamaño de la rotura, demora de intervención, mujeres. Los pacientes con rotura tipo I-B tienen mejor resultado total en el TCM que los tipos I-A y III. A mayor demora se observan peores resultados, tanto de la EVA como del TCM. Las mujeres presentan resultados peores y estadísticamente significativos tanto en la EVA (p=0,00) como en el TCM (p=0,01).(AU)

Objective: To carry out a review of degenerative subscapularis ruptures (SSC) after their arthroscopic repair and to evaluate whether the results are comparable in terms of pain and function to those of younger patients with traumatic ruptures. Methods: The data of 80 SSC tears of the 660 rotator cuff tears operated on by the same team of surgeons from June 2008 to June 2018 were retrospectively reviewed. The clinical data of the surgical indications were collected: age, gender, laterality, intervention delay, associated pathologies, location of pain, value of the Visual Analogue Scale (VAS) and the Constant-Murley test (CMT); surgical data were also collected: type and size of lesion, associated biceps injury and associated surgical procedure, coracoid stenosis and associated surgical procedure, number and type of anchors used. A statistical study was performed with multiple linear regression test, parametric tests (Student's t or ANOVA) and non-parametric tests. Results: Of 80 patients, 36 were women (45%) and 44, men (55%); mean age 61years (range 47 to 81); mean delay of surgery 3.5months (range 1 to 6); right shoulder affected in 46 cases (57.5%), left in 34 (42.5%); 22 (27.5%) were isolated lesions, 58 (72.5%) were associated with supraspinatus rupture (SE). The mean improvement was 5.0 points in terms of the VAS and 39.9 points on average in the CMT. New breakage rate, 1.25%. Adverse factors: size of the tear, delay in intervention, women. Patients with type I-B rupture have a better overall result in the CMT than types I-A and III. The longer the delay, the worse results are observed, both for the VAS and the CMT. Women present worse and statistically significant results both in the VAS (P=.00) and in the CMT (P=.01). Conclusions: Excellent and good results have been obtained in this group of patients, but there are adverse factors such as the size of the tear, the duration of the symptoms and the association of other pathologies, especially in women.(AU)

Longitudinal study in patients with myotonic dystrophy type 1: correlation of brain MRI abnormalities with cognitive performances.

PURPOSE: Myotonic dystrophy type 1 (DM1) is a muscular dystrophy with neurological, cognitive, and radiological abnormalities. The developmental or degenerative nature of these abnormalities, and their progression over time, remains unclear. The aim of this study is to perform a longitudinal assessment of imaging and cognitive performances in a group of patients with DM1. METHODS: A longitudinal observational study was conducted in a group of 33 DM1 patients. All patients underwent cognitive and MRI evaluation, including the use of structural and diffusion tensor imaging techniques, at baseline and follow-up evaluation (4 years). Longitudinal changes in white matter lesion (WML), volumetric analysis, and diffusivity values were assessed and correlated with neuropsychological test findings. RESULTS: An increase in WML was observed in 16 patients (48.5%). An increase in ventricular system volume and a decrease in volume of the left thalamus, caudates, putamen, and hippocampus were observed (p < 0.001). Global cortical volume showed a significant decrease (p < 0.001), although no changes were observed in white matter volume. A significant increase in mean diffusivity and decrease in fractional anisotropy for the white matter were found (p < 0.001). Neuropsychological evaluation showed a significant deterioration in test performance that measures working memory (Letter-Number Sequencing, p = 0.049) and visuospatial skills (Benton Visual Retention Test, p = 0.001). These findings were significantly associated with WML load (working memory p = 0.002 and visuospatial skills p = 0.021) and mean diffusivity increase (visuospatial skills p = 0.003 in the corpus callosum and working memory p = 0.043 in the right cerebral white matter). CONCLUSION: White matter and grey matter involvement in DM1 patients is progressive. Patients experience a worsening in cognitive impairment that correlates with white matter involvement. These findings support the neurodegenerative nature of this disease.

Sonographic Measurement of the Patellar Tendon Should Predict Autograft Bone Patellar Tendon Bone (BPTB) Size: Comparison of Anatomical and Clinical Findings.

The use of BPTB autograft is frequently used in ACL reconstruction, however, the risk of potential failure in patients with an anatomically unfavorable patellar tendon may predispose to reconstruction failure. Anatomical study of the extensor apparatus of the knee can provide knowledge about the best option obtain the graft and perform a better preoperative planning. Musculoskeletal ultrasound is a simple, reproducible, affordable technique that could be valid for patellar tendon evaluation. The objective of this study is to evaluate the reproducibility of the patellar tendon measurements by ultrasound and compare them with anatomical measurements, both in cadaver and patients undergoing ACLR. The study consists of two phases; first anatomical study in cadaver. The ultrasound measurement was performed by determining the length, width and thickness of the patellar tendon, both by ultrasound and anatomical dissection. The second phase is a cohort of 42 patients pending surgical ACLR. Previous ultrasound and intraoperative measurements were obtained. Regarding the anatomical study, statistical analysis did not show any differences comparing the measurements in length (p = ns) and thickness (p = ns) of the patellar tendon, although differences were obtained when comparing the results obtained for the width of the tendon after the ultrasound and anatomical measurement (p < 0.001). Same results were obtained in second phase of the study. The reproducibility of ultrasound measurements of the PT is comparable to intraoperatively measurements (without width measurement). These findings can be useful for preoperative planning in the reconstruction of ACL with BPTB Graft and to assess technical modifications prior to surgery.

Modificaciones en la altura patelar por el uso del injerto hueso-tendón-hueso / Changes in patellar height due to bone-tendon-bone graft

Objetivo: Las complicaciones asociadas al uso de injertos del ligamento cruzado anterior (LCA) son frecuentes. Los cambios en la altura, sobre todo de la patela baja, pueden ser la razón de la aparición de dolor en la zona anterior de la rodilla. Diversos estudios han asociado la reconstrucción del LCA mediante la técnica de injerto hueso-tendón-hueso con patela baja. Métodos: Cuarenta y tres pacientes con reconstrucción del LCA mediante injerto hueso-tendón-hueso fueron incluidos en el presente estudio. Todos los pacientes fueron sometidos a la misma cirugía, con el cierre del paratendón del tendón rotuliano. Se realizó un estudio radiológico antes de la cirugía y 2 años después de la misma. En todos los casos se estudió el índice Insall-Salvati, el corte axial y la inclinación patelar. Como control se utilizó la rodilla sana contralateral del paciente. Resultados: No se encontraron diferencias significativas entre el estudio preoperatorio y el realizado tras 2 años de la cirugía. Conclusiones: El uso del tendón patelar con cierre del paratendón en la reconstrucción del LCA no ha demostrado modificar la altura patelar en estudios radiológicos a los 2 años de seguimiento

Purpose: Complications related to anterior cruciate ligament (ACL) graft are common. Change in height, especially patella baja, can be a cause of anterior knee pain. Several studies have related ACL reconstruction with bone-tendon-bone graft to patella baja. Methods: Forty-three patients with ACL reconstruction using a with bone-tendon-bone graft were included in this study. All patients underwent the same surgery, with closure of the paratenon of the patellar tendon. A radiological study was performed before surgery and 2 years after surgery. The Insall-Salvati index, axial view and patellar tilt were analyzed in all patients. The healthy contralateral knees were used as the control group. Results: No significant differences were observed from the preoperative measurements or at the 2-year follow-up. Conclusions: The use of patellar tendon with closure of the paratenon in ACL reconstruction was not shown to modify patellar height within the radiological follow-up of two years

Assessing long-term return to play after hip arthroscopy in football players evaluating risk factors for good prognosis.

PURPOSE: Groin pain is the third most common disease in football players and has often been associated with hip pathology such as femoroacetabular impingement and labral lesions. Hip arthroscopy offers possibilities of function restoration via minimally invasive procedures. The aim of this study is to evaluate professional football player's injuries and their return to play after hip arthroscopy for FAI and labral injuries. METHODS: Patients that underwent hip arthroscopy between 2009 and 2014 were selected retrospectively. From this population, only professional soccer players competing at national level were included (Tegner 10). Arthroscopic surgery was proposed in patients with persistent pain. All patients were assessed for VAS score preoperatively and at 3, 6, 12 and 24 months post-op. HOS (sport and DLA) and mHHS tests were performed at the same time periods. RESULTS: All patients were men with a mean age of 26.5 ± 7.1 years old. Preoperative VAS (7.4 ± 1.3), HOS ADL (67.7 ± 5.5), HOS sport (37.6 ± 18.7) and mHHS (72.5 ± 8.8) showed improved scores during long-term follow-up. Time to return to play was 10.8 months (SD ± 4.3), with range between 4 and 20 months. Mean follow-up was 45.4 ± 15.6 months (range from 26 to 72 months). No differences were observed between non-active and active patients at final follow-up with respect to chondral lesions, but significant differences were observed with reference to management of the labrum (p = 0.031), where a higher rate of labrectomies existed among inactive patients and a higher rate of suture among active patients. CONCLUSIONS: Hip arthroscopy is a safe procedure with very good return to play results, but for optimized return to football one should consider patient age at the time of surgery, the condition of the labrum and low scores on the Harris Hip Score (mHHS) and HOS (sport version) as predictive factors for poor prognosis. Level of evidence IV.

Brain Involvement in Myotonic Dystrophy Type 1: A Morphometric and Diffusion Tensor Imaging Study with Neuropsychological Correlation.

OBJECTIVE: Myotonic dystrophy type 1 (DM1), the most prevalent inherited neuromuscular disease in adults, is a genetic multisystem disorder with a well-established but not well-characterized cerebral involvement. The aim of this study was to evaluate the presence of white matter and gray matter abnormalities in DM1 patients and to investigate their relationship with neurocognitive dysfunction. METHODS: A total of 42 DM1 patients and 42 healthy controls were included in the study. Clinical, cognitive, and magnetic resonance imaging evaluations, including the use of structural and diffusion tensor imaging (DTI) techniques, were performed. White matter lesion (WML) load, volumetric analysis, and diffusivity changes were assessed and correlated with clinical and neuropsychological test findings. RESULTS: WMLs were significantly more frequent in DM1 patients (p < .001), and anterior temporal lobe lesions were only found in the patient group. Global and regional cortical volume loss and corpus callosum atrophy were found. Diffuse white matter DTI abnormalities, including fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity were observed with sparing of the internal capsule. Subcortical structures showed volume loss and increased median diffusivity. Neuropsychological evaluation showed significant impairment in several cognitive functions, but only visuospatial impairment was correlated with white matter abnormalities and cortical atrophy. Daytime sleepiness was associated with WML and ventral diencephalon and pallidum volume loss. CONCLUSION: DM1 produces a widespread involvement of white matter and gray matter, including cortical and subcortical structures. These structural abnormalities are involved in the progressive neuropsychological functional impairment in these patients.

Hip arthroscopy complications regarding surgery and early postoperative care: retrospective study and review of literature.

PURPOSE: The purpose is to describe the rate of complications in a series of hip arthroscopies performed at our center, as well as perform a systematic review of the current literature in order to compare our outcomes. METHODS: Two hundred and fifty-eight patients affected of femoroacetabular impingement and treated with hip arthroscopy have been studied. All minor and major complications were studied during the first postsurgery year. Furthermore, a systematic review was performed comparing major and minor complications with our series. Two attending orthopedic surgeons selected the different studies with the same inclusion and exclusion criteria, remaining with 48 studies that have been reviewed and included in the present study. RESULTS: Mean age was 36.6 years old (SD 17.45), and the ratio men:women was 137:121. The mean complication rate observed was 14.34% (37/258) of global complications. Only three patients showed major complications: femoral neck fracture, septic arthritis and avascular necrosis of the femoral head. Any of these patients had permanent side effects. CONCLUSIONS: Hip arthroscopy has a low rate of major complications, but a higher number of minor complications that could be avoided with certain preventive measures.

Calentamiento neuromuscular estructurado como prevención de lesiones en futbolistas profesionales jóvenes / Structured neuromuscular warm-up for injury prevention in young elite football players

Objetivo. Recopilar evidencia sobre los resultados de los programas de calentamiento neuromuscular estructurados sin equipo adicional como método de prevención de lesiones de no contacto en futbolistas jóvenes profesionales. Material y métodos. Se realizó durante marzo y abril de 2013 una búsqueda de literatura (PubMed, Biblioteca Cochrane Plus, The American Journal Sports of Medicine, The British Journal of Sports Medicine y el motor de búsqueda Trip Database). Resultados. Se obtuvieron, tras aplicar los criterios de inclusión y exclusión, un total de 6 estudios (3 ensayos clínicos, un estudio de cohortes y 2 revisiones sistemáticas). El programa «FIFA 11+» mostró una reducción de lesiones en un 33-57%, desgranándose en un 52% en rodilla, 22% en tobillo, 40% en síndrome de estrés medial tibial, 50% en muslo posterior y 21% en el anterior, y 12% en la zona inguinal. El programa «FIFA 11» mostró una reducción del 58% en esguinces de tobillo y del 27% en lesiones de LCA. Otros programas específicos de prevención de lesiones de LCA las redujeron en un 74% y «Knäkontroll, SISU Idrottsböcker©» en un 64%. El programa «HarmoKnee» redujo lesiones de rodilla en un 78%. Discusión. Se observaron varias debilidades metodológicas, pero parece que existe la tendencia a que un calentamiento que contenga como base estiramientos, fortalecimiento y ejercicios de equilibrio, realizado durante más de tres meses y de manera regular podría prevenir lesiones. Conclusiones. El programa «FIFA 11+» podría ser una buena medida preventiva de lesiones aplicando su programa de calentamiento estructurado. A pesar de ello, nuevos estudios mejor diseñados se requieren para poder valorar bien esta evidencia (AU)

Objective. To gather evidence about the outcomes of structured neuromuscular warm-up programs without additional equipment, as prevention of non-contact injuries in young professional soccer players. Material and methods. A literature search was conducted during March and April 2013 (PubMed, Cochrane Library, The American Journal of Sports Medicine, The British Journal of Sports Medicine and the search engine Trip Database). Results. After applying the inclusion and exclusion criteria, a total of 6 studies were obtained (3 clinical trials, one cohort study and 2 systematic reviews). «FIFA 11+» program showed a reduction of injuries of between 33% and 57%. These included 52% in knee, 22% in ankle, 40% in medial tibial stress syndrome, 50% in posterior thigh, and 21% in the anterior, and 12% in the groin area. «FIFA 11» program showed a 58% reduction in ankle sprains and 27% in anterior cruciate ligament (ACL) injuries. Other specific programs to prevent ACL injuries reduced them by 74% and «Knäkontroll, SISU Idrottsböcker©» by 64%. «HarmoKnee» program reduced knee injuries by 78%. Discussion. Several methodological weaknesses were observed, but it seems that there is a trend toward a warm-up that contains basic stretching, strengthening and balance exercises, which performed for more than three months and regularly, could prevent injuries. Conclusions. «FIFA 11 +» program might be a good preventive measure of injuries by implementing its program of structured warm- up. In any event new, better designed, studies are needed to assess this evidence (AU)

[Anterior cruciate ligament ganglion: a case report]. / Ganglión en ligamento cruzado anterior: a propósito de un caso.

Intraarticular ganglions are rare and they are usually incidental findings of MRIs and arthroscopies. We report the case of a male athlete with this condition affecting the anterior cruciate ligament. The most frequent symptoms include pain that worsens with activity, and motion limitations. The MRI shows the typical signs of a ganglion and it is the most specific and sensitive test. Arthroscopy is used for both the diagnosis and the treatment of this condition. A late diagnosis turns arthroscopic resection into a complicated or impossible procedure that at times warrants extensive debridement of the anterior cruzate ligament.

[Treatment of late onset Perthes disease with hip arthroscopy and arthrodiastasis with an external fixator. Case report]. / Tratamiento de la enfermedad de perthes tardía mediante artroscopía de cadera y artrodistasis con fijador externo. A propósito de un caso y revisión de la literatura.

BACKGROUND: The prognosis of late onset Perthes cases is usually poor and the proposed treatments vary based on the surgeon's preferences and experience, as well as on the available resources. Most of them are salvage procedures with a short follow-up and non-standardized application criteria. METHODS: Hip arthroscopy and arthrodiastasis with external fixator are indicated for certain situations in Perthes disease. Based on the results obtained with each of these techniques separately, both of them were used to treat a case of Perthes disease involving a poor prognosis. RESULTS: Results two years after surgery are good. CONCLUSIONS: The use of both techniques together may produce a good result in these patients.

[Anterior tibial tubercle fracture in teenagers. Clinical cases]. / Fractura de la tuberosidad anterior de la tibia en el adolescente. Casos clínicos.

INTRODUCTION: Anterior tibial tubercle fractures are relatively infrequent and occur mainly in young athletes 14 to 17 years old. Most fractures result from jumping during sports activities. METHODS: We describe two cases of anterior tibial tubercle fractures. The latter were Ogden IIIA and IIIB. In both cases treatment consisted of open reduction and internal fixation with cannulated screws. DISCUSSION: The mechanism of injury in the first case is more common than the one in the second case. The first case occurred after jumping to receive a pass during a basketball game. The second one occurred while playing soccer. The patient was kicked on the quadriceps musculature. Both cases involved functional disability. CONCLUSION: Biomechanically, the mechanism of injury in the second case increased the tension on the extensor apparatus. We performed synthesis with cannulated screws and obtained good results without complications.

Use of polymethylmethacrylate to treat pigmented villonodular synovitis in the posterior compartment of the knee.

Pigmented villonodular synovitis (PVNS) is a benign process that mainly affects the knee joint. There are two types of PVNS, a localised and a diffuse form. Although adjuvant therapies are possible, the treatment consists of arthroscopic or open synovectomy of the affected area. The most common complication is local recurrence. We report the case of a patient with PVNS and osteolysis of the femoral condyle, treated with anterior arthroscopic synovectomy and posterior approach for the treatment of the femoral condyle erosion. The bone erosion was treated with polymethylmethacrylate (PMMA) cement. There are no publications indexed in our knowledge that explain the treatment of PVNS associated with bone erosion by PMMA. Nine years after the procedure, the patient is leading a fully active life with no evidence of active disease.
