Range of Motion and Injury Occurrence in Elite Spanish Soccer Academies. Not Only a Hamstring Shortening-Related Problem.
2020
Sanz, A, Pablos, C, Ballester, R, Sanchez-Alarcos, JV, and Huertas, F. Range of motion and injury occurrence in elite Spanish soccer academies. Not only a hamstring shortening-related problem. J Strength Cond Res 34(7): 1924-1932, 2020-Age-related development of range of motion (ROM) during an active hip flexion (active straight leg raise) and its relationship with hamstring injury occurrence were examined in 1657 young male soccer players (9-18 years of age). Age-related differences in ROM showed a significant decrease from U9 to U11 (p = 0.001), from U11 to U13 (p0.005), and from U9 to U13 (p0.001), whereas ROM increased from U13 to U15 and from U13 to U18 (both p's0.001). Interestingly, …
M-mode Ultrasound Examination of Soleus Muscle in Healthy Subjects: Intra- and Inter-Rater Reliability Study
2020
Objective: M-mode ultrasound imaging (US) reflects the motion of connective tissue within muscles. The objectives of this study were to evaluate inter-rater and intra-rater reliability of soleus muscle measurements between examiners with different levels of US experience in asymptomatic subjects and to investigate the level of soleus muscle isometric activity in two positions (knee extended and knee flexed at 30°
Different sitting positions influence cross country sit skiers performance : Sitting position influence on force generation and cycle characteristics
2018
Cross country sit skiing is a Paralympic discipline in which athletes due to physical impairment ski sitting on a sit-ski. The impairment influences performance directly and also through sitting position. Athletes with a better trunk control usually adopt a sitting position called “kneeing” in which the hip joints are higher than the knee joints. In contrast, athletes with high impact of impairment prefer a sitting position called “knee high” in which the hip joints are lower than the knee joints. Able bodied athletes skiing on the ergometer in these two sitting positions showed different performance. However, to the best of authors’ knowledge, no studies have examined performance, force pr…
Enucleación aislada del astrágalo
1988
Isolated enucleation of the talus is reported. It is an uncommon injury. The management and complications are analised; emphasizing the indication of an early reduction.
Osteocondritis disecante de astrágalo : a propósito de un caso de localización bilateral
1988
A case of bilateral osteochondritis dissecans of the Talus is reported. A review of the aetiologic factors, clinical assessment and therapeutic trends is described.
La utilización de la fibra de carbono en las lesiones de los ligamentos colaterales de la rodilla : Estudio preliminar
1988
A preliminary report on the usage of carbon fibre prothesis in the repair of acute and chronic lesions of the lateral ligaments of the knee is presented. The authors suggest the sistematic use of carbon fibre as augmentation device in the repair of acute tears in the lateral ligaments of the knee joint.
Rodilla del saltador
1988
61 jumper's knees (fifty patients) are studied. Predisposing factors, clinical and radiographyc manifestacions are relationated in order to obtain a more effective treatment. 50% showed radiographyc disturbances of the patellar vertex, 25% had hight patella and 20% condromalacia was associated. Surgery was performed in 10 knees, and conservative treatment in the rest. Poor results and relapses arose in later treated cases. Prevention and early treatment are very important in these cases.
La insercion distal del musculo semimembranoso
1987
The anatomy and function of the distal insertion of the semimembranous muscle in seventeen knees was deseribed in detail
Fracturas de estrés en la escápula y factores de riesgo : a propósito de un caso y revisión de la literatura
2017
Scapula stress fracture is an uncommon injury. Some cases have been described in sportsmen, handworkers, rotator cuff arthropathy and reversed shoulder arthroplasty; being infrequent the association with crutch´s repetitive load. Treatment should be individualized and depends of patient characteristics, comorbidities and displacement. The article describes a case of a scapular spine´s stress fracture, and a literature review is being performed. Case Report is an 86 year old woman with corticoids treatment history and ilio-pubic ramus fracture. She walked with a crutch since that fractures. Patient begins gradually with pain and limited mobility in shoulder without trauma. CT scan showed fra…
Posterior Shoulder Instability
2020
Posterior shoulder instability is often hard to diagnose with clinical examination. Patients generally present with vague pain, weakness, and/or joint clicking but less frequently complaining of frank sensation of instability. Imaging examinations, especially MR imaging and magnetic resonance arthrography, have a pivotal role in the identification and management of this condition. This review describes the pathologic micro/macrotraumatic magnetic resonance features of posterior shoulder instability as well as the underlying joint abnormalities predisposing to this condition, including developmental anomalies of the glenoid fossa, humeral head, posterior labrum, and capsular and ligamentous …
