Neumoencéfalo: una inusual complicación de la artrodesis lumbar. Caso clínico y revision de la literatura / Pneumocephalus: an unusual complication of lumbar arthrodesis. A clinical case and literature review

El neumoencéfalo es una complicación poco frecuente pero grave de la cirugía de la columna vertebral, su manejo y fisiopatología no es ampliamente conocida. La incidencia de neumoencéfalo sintomático a tensión, secundario a una artrodesis vertebral posterior es desconocida. Caso clínico. Presentamos el caso de una paciente mujer de 41 años de edad, con diagnóstico de discopatía L3-L4, L4-L5 y hernia discal izquierda L4-L5. Se realizó una artrodesis vertebral posterior L3-L5, discectomías L3-L4 y L4-L5 y liberación de la raíz L5 izquierda, sin complicaciones aparentes. Transcurridas 24 h después de la cirugía, la paciente inicia cuadro de cefalea generalizada de fuerte intensidad, rigidez de nuca y disartria. Se realizan TAC y RMN que muestran un enorme neumoencéfalo en el espacio subaracnoideo, a predominio del lóbulo frontal izquierdo, sin desplazamiento de la línea media, con origen en el conducto raquídeo lumbar. La paciente fue tratada de forma conservadora, presentando a partir de las 72 h mejoría neurológica progresiva, hasta la normalización clínica y radiológica después de 7 días. Discusión. El neumoencéfalo es una complicación rara pero potencialmente grave de la cirugía de columna, relacionada en la mayoría de los casos con desgarro dural accidental durante la cirugía. La mayoría de las colecciones son pequeñas, se comportan de forma benigna, y responden al tratamiento conservador. En un gran número de pacientes, puede comportarse como cualquier lesión ocupante de espacio, por lo que se necesita un alto grado de sospecha clínica para hacer el diagnóstico y tratamiento oportuno, y prevenir la morbimortalidad no deseadas (AU)

Pneumocephalus is an uncommon but serious complication of spinal surgery and its management and pathophysiology is not widely recognized. The incidence of symptomatic tension pneumocephalus secondary to posterior spinal arthrodesis is unknown. Case report. The case is reported of a rare case of a 41 year old woman with diagnosis of L3-L4, L4-L5 disc disease and left disc herniation L4-L5. A posterior spinal arthrodesis L3-L5, L3-L4 and L4-L5 discectomies and release of the left L5 root, was performed without apparent complications. Twenty-four hours after surgery the patient developed generalized headache, neck stiffness, and dysarthria. MRI and CT scans revealed a huge pneumocephalus in the subarachnoid space, predominantly in the left frontal lobe without midline shift, which originated in the lumbar spinal canal. The patient was treated conservatively, with progressive neurological improvement after 72 hours, and clinical and radiological normalization after 7 days. Discussion. Pneumocephalus is a rare but potentially serious complication of spine surgery related in most cases with inadvertent dural tear during the operation. Most collections are small, behave benign, and respond to conservative therapy. In the present case, an inadvertent dural tear, produced a pneumocephalus. A high degree of suspicion is needed to make the diagnosis, prompt treatment, as well as remedying the source of air to prevent unwanted morbidity and mortality (AU)

Propuesta de algoritmo terapéutico para hallux rigidus / Treatment algorithm proposed for hallux rigidus

El hallux rigidus es la artrosis más frecuente en el pie y tobillo y la segunda afectación más importante de la primera articulación metatarsofalángica tras el hallux valgus. Si no se trata, puede producir importantes alteraciones en la marcha, movilidad y actividades de la vida diaria. Pretendemos en este artículo de revisión presentar un algoritmo de tratamiento completo para todos los grados de esta enfermedad, tras una concienzuda revisión bibliográfica.

Hallux rigidus is the most frequent arthrosis of the foot and ankle and the second most important condition involving the first metatarsophalangeal joint after hallux valgus. If left untreated, it may cause important alterations in gait, mobility and activities of daily living. The purpose of this review article is to describe a complete treatment algorithm for all grades of this condition, after a thorough bibliographic review.

[Results of arthrodiastasis in postraumatic ankle osteoarthritis in a young population: prospective comparative study]. / Resultados de la artrodiastasis en la artropatía postraumática de tobillo en población joven: estudio prospectivo comparativo.

INTRODUCTION: The most common cause of osteoarthritis of the ankle is post-traumatic, and although tibiotalar arthrodesis remains the surgical gold standard, a number of techniques have been described to preserve joint mobility, such as joint distraction arthroplasty or arthrodiastasis. OBJECTIVE: To evaluate the functional outcome and changes in Visual Analogue Scale (VAS) for pain after the application of the distraction arthroplasty for post-traumatic ankle osteoarthritis. PATIENTS AND METHODS: A prospective comparative study of a group of 10 young patients with post-traumatic ankle osteoarthritis treated by synovectomy and arthrodiastasis, compared to a control group of 10 patients treated by isolated synovectomy. Results were calculated using the AOFAS scale and the VAS for pain before and after treatment. RESULTS: As regards the pain measured by VAS, no difference was observed between the two groups before surgery (P=.99), but there was a difference at 3 months (P<.001), 6 months (P=.005), and 12 months (P=.006). No differences were observed in the AOFAS scale between the two groups before surgery (P=.99), or at 3 months (P<.99), but there was a difference at 6 months (P<.001). CONCLUSIONS: Ankle arthrodiastasis is effective in reducing pain in post-traumatic ankle arthropathy, and is superior to isolated synovectomy.
