ABSTRACT

A neurectomia digital palmar é utilizada em animais que apresentam dor devido às doenças degenerativas podais que não respondem ao tratamento conservativo. Diversas técnicas de neurectomia foram desenvolvidas com objetivo de obter menor trauma cirúrgico, evitando o desenvolvimento de neuroma doloroso,considerado uma das principais complicações da secção nervosa. Para os animais atletas registrado sem associações de criadores, a neurectomia é considerada doping por não tratar a doença de base da claudicação,impedindo-o de participar de eventos esportivos. A presente revisão bibliográfica abrange estudos das diferentes técnicas de neurectomia, avaliando suas indicações, vantagens e desvantagens. As técnicas relatadas apresentam diferentes resultados quando comparadas em relação ao tempo e taxa de formação do neuroma, podendo este ser doloroso ou não.


Palmar digital neurectomy is utilized in horses suffering from degenerative and painful conditionslocalized in the foot, unresponsive to medical and conservative forms of therapy. Different techniques of palmar digital neurectomy were developed in order to minimize surgical trauma and avoid the most commoncomplication associated with nerve transection, that is painful neuroma. Neurectomy is considered doping inanimais registered in breeders' associations, once it does not represent a treatment for the underlying condition,and horses that have had surgery are not allowed to compete. This literature review describes different neurectomy techniques, evaluating their indications, advantages and complications. Presented techniques vary in results when rate and time to neuroma formation are considered, be it painful or not.

ABSTRACT

OBJECTIVE: The nerve conduction findings in interdigital neuropathy of the foot (IDN; Morton's neuroma) have rarely been reported. We analyzed the nerve conduction data in 23 patients with suspected IDN studied between 1982 and 2002. METHOD: Diagnosis of IDN was made on the basis of clinical features. All patients underwent routine nerve conduction studies and a near-nerve needle sensory nerve conduction study of the interdigital nerves by Oh's method in the symptomatic foot. RESULTS: Of the 23 patients, the diagnosis of definite IDN was made in 13 cases and of possible NDN in the others cases. Nineteen were females. Twenty two patients had only one nerve affected. One patient had two nerves affected. The III-IV interdigital nerve was affected in 17 cases and the II-III interdigital nerve in 7 cases. The near-nerve needle nerve conduction showed abnormality in the affected interdigital nerves in all definite IDN cases and confirmed the diagnosis of IDN in 10 cases by the abnormal dip phenomenon (a selective decrease of 50% or more in the sensory CNAP amplitude of the affected nerve compared with that of the preceding interdigital nerve). In 11 possible IDN cases, IDN was identified by the abnormal dip phenomenon. CONCLUSION: The near-nerve needle sensory nerve conduction of the interdigital nerves is a highly sensitive diagnostic test, and abnormal dip phenomenon is the most characteristic electrophysiological marker for the diagnosis of IDN.

OBJETIVO: Os achados da condução nervosa na neuropatia interdigital do pé (NIP) têm sido raramente descritos. Nós analisamos os dados da condução nervosa de 23 pacientes com suspeita de NIP entre 1982 e 2002. MÉTODO: O diagnóstico de NIP foi clínico. Todos os pacientes foram submetidos a estudos de condução nervosa de rotina e ao estudo de condução sensitiva dos nervos interdigitais com agulha justa-neural pelo método de Oh. RESULTADOS: Dos 23 pacientes, o diagnóstico de NIP foi definitivo em 13 casos é possível nos demais. Dezenove pacientes eram mulheres e 22 tinham somente um nervo afetado. Apenas um paciente teve dois nervos comprometidos. O nervo interdigital III-IV foi afetado em 17 casos e o nervo interdigital II-III em 7 casos. A condução nervosa justa-neural foi anormal nos nervos interdigitais acometidos em todos os casos definitivos e confirmou o diagnóstico de neuropatia interdigital em 10 casos pelo fenômeno da diminuição de amplitude anormal (uma diminuição seletiva de 50 por cento ou mais da amplitude do PANS do nervo afetado quando comparado com o nervo anterior. Em 11 casos possíveis, a neuropatia interdigital foi identificada pelo fenômeno da diminuição de amplitude anormal. CONCLUSÃO: A condução nervosa sensitiva justa-neural dos nervos interdigitais do pé é um teste diagnóstico altamente sensível e o fenômeno da diminuição da amplitude anormal é o marcador eletrofisiológico mais característico para o diagnóstico de neuroma de Morton.
