Cubital compressive neuropathy in the elbow: in situ neurolysis versus anterior transposition – comparative study / Neuropatia compressiva cubital no cotovelo: neurólise in situ versus transposição anterior–Estudo comparativo

Objective: To compare the results from two of the most commonly used surgical techniques: in situ decompression and subcutaneous transposition. The processes of patients treated surgically in a public university hospital between January 2004 and December 2011 were reviewed. Cases of proximal compression of the nerve, angular deformity of the elbow and systemic diseases associated with non-compressive neuropathy were excluded. Methods: Ninety-seven cases were included (96 patients). According to the modified McGowan score, 14.4% of the patients presented grade Ia, 27.8% grade II, 26.8% grade IIb and 30.9% grade III. In situ neurolysis of the cubital was performed in 64 cases and subcutaneous anterior transposition in 33. Results: According to the modified Wilson and Knout score, the results were excellent in 49.5%, good in 18.6%, only satisfactory in 17.5% and poor in 14.4%. In comparing the two techniques, we observed similar numbers of excellent and good results. Grades IIb and III were associated with more results that were less satisfactory or poor, independent of the surgical technique. Conclusion: Both techniques were shown to be efficient and safe for treating cubital tunnel syndrome...

Objetivo: Comparar os resultados de duas das técnicas cirúrgicas mais usadas, a descompressão in situ e a transposição subcutânea. Foram revistos os processos dos doentes tratados cirurgicamente num hospital universitário público entre janeiro de 2004 e dezembro de 2011. Foram excluídas compressões proximais do nervo, deformidades angulares do cotovelo e doenças sistêmicas associadas a neuropatia não compressiva. Metodos: Foram incluídos 97 casos (96 doentes). Segundo o escore modificado de McGowan, 14,4% dos pacientes encontravam-se no Grau Ia, 27,8% no II, 26,8% no IIb e 30,9% no III. A neurólise in situ do cubital foi feita em 64 casos e a transposição anterior subcutânea em 33. Resultados: Segundo o escore modificado de Wilson e Knout, os resultados foram excelentes em 49,5%, bons em 18,6%, apenas satisfatórios em 17,5% e pobres em 14,4%. Na comparação das duas técnicas observamos valores similares de resultados excelentes ou bons. Os graus IIb e III estão associados a mais resultados menos satisfatórios ou maus independentemente da técnica cirúrgica. Conclusão: As duas técnicas se revelam eficientes e seguras no tratamento do síndrome do túnel cubital...

Anatomical study of the third palmar interosseous muscle and its dominate nerve / 中华显微外科杂志

Objective To explore the anatomical characteristic of the third palmar interosseous mus- cle as well its dominate nerve,and to investigate the anatomical basis of difficult recovery of digitus minimus adduction.Methods Twenty aduh fresh hands without deformity and trauma were obtained.Dissect and observe the third palmar interosseous muscle and its dominate nerve and adjacent structure under surgical mi- croseope,measure the size of the third pahnar interosseous muscle and its dominate nerve,the data were pro- cessed by stastistics method.Results Among palmar interosseous muscles and its dominate nerves,the third palmar interosseous muscle and its dominate nerve is the smallest.There are conspicuous tendon bundle on the surface of the third palmar interosseous muscle partly,which have a potential compression on the third palmar interosseous muscle dominting nerve.Conclusion The third palmar interosseous muscle is the smal- lest among palmar interusseous muscles and it is the only digitus minimus adduction muscle.The sominating nerve of the third palmar interosseous muscle is small anti the tendon bundle of the third palmar interosseous muscle have a potential compression.All these can cast light on diffcult recovery of digitus minimus adduction.
