Objective:To evaluate the fatty infiltration and atrophy of the supraespinatus in the pre- and postoperative of a rotator cuff lesion (RCL), by MRI.Methods:Ten patients with full-thickness rotator cuff tears who had undergone surgical arthroscopic rotator cuff repair between September and December 2011 were included. This is a prospective study, with analysis and comparison of fatty infiltration and atrophy of the supraespinatus. The occupation ratio was measured using the magic selection tool in Adobe Photoshop CS3(r) on T1 oblique sagittal Y-view MRI. Through Photoshop, the proportion occupied by the muscle belly regarding its fossae was calculated.Results:There was a statistically significant increase in the muscle ratio (p=0.013) comparing images pre and postoperative, analyzed by the Wilcoxon T test.Conclusion:The proportion of the supraspinal muscle above the pit increases in the immediate postoperative period, probably due to the traction exerted on the tendon at the time of repair.

OBJETIVOS: Determinar a idade óssea nos pacientes com paralisia cerebral (PC) espástica acompanhados no Ambulatório de Doenças Neuromusculares e comparar com a idade cronológica e correlacionar com os diferentes tipos (hemiparético, diparético, tetraparético), sexo e função motora. MÉTODOS: Analisados 401 pacientes com PC espástica, com idade entre três meses e 20 anos, submetidos a radiografias das mãos e punhos bilaterais e anotado a idade óssea por dois observadores independentes de acordo com o Atlas Greulich & Pyle. RESULTADOS: Quanto a distribuição topográfica, houve um atraso significante (p<0,005) nos tetraparéticos (17,7meses), nos hemiparéticos (10,1 meses) e diparéticos (7,9 meses). No grupo de hemiparéticos, a idade óssea média no lado acometido foi de 96,88 meses e no lado não acometido de 101,13 meses (p<0,005). Em relação ao estado funcional, os não deambuladores demonstraram atraso na idade óssea em relação à idade cronológica de 18,73 meses (p<0,005). Observou-se um maior atraso no sexo masculino (13,59 meses) do que no sexo feminino (9,63 meses), mas não estatisticamente significante (p=0,54). CONCLUSÕES: Há um atraso da idade óssea em relação à idade cronológica influenciado pelo tipo de topografia da espasticidade, nível funcional e sexo na PC. Nível de Evidência IV, Série de Casos.

OBJECTIVE: To compare the chronological age and bone age among cerebral palsy patients in the outpatient clinic and its correlation with the type of neurological involvement, gender and functional status. METHODS: 401 patients with spastic cerebral palsy, and ages ranging from three months to 20 years old, submitted to radiological examination for bone age and analyzed by two independent observers according Greulich & Pyle. RESULTS: In the topographic distribution, there was a significant delay (p<0.005) in tetraparetic (17.7 months), hemiparetic (10.1 months), and diparetic patients (7.9 months). In the hemiparetic group, the mean bone age in the affected side was 96.88 months and the uncompromised side was 101.13 months (p<0.005). Regarding functional status, the ambulatory group showed a delay of 18.73 months in bone age (p<0.005). Comparing bone age between genders, it was observed a greater delay in males (13.59 months) than in females (9.63 months), but not statistically significant (p = 0.54). CONCLUSION: There is a delay in bone age compared to chronological age influenced by the topography of spasticity, functional level and gender in patients with cerebral palsy.
