Sin embargo, esta cirugía debe constituir el último recurso después de un tratamiento médico, salvo complicaciones neurológicas, aunque no existe un consenso sobre las indicaciones. Incluso aunque los resultados se consideran muy buenos, el postoperatorio no siempre es favorable. Las hernias discales pueden tener varias localizaciones: medial, posterolateral, foraminal y extraforaminal. La estrategia quirúrgica debe adaptarse en función de la topografía de la hernia, del antecedente de una recidiva, así como del estado de los platillos vertebrales adyacentes. En este artículo se describe la discectomía por vía posterior medial, la discectomía posterolateral según la técnica de Wiltse, las discectomías endoscópicas transforaminal e interlaminar, así como la cirugía de reintervención discal. Las prótesis lumbares y las artrodesis no se expondrán en este artículo.

Pedicle posterior wedge osteotomy is a technically demanding procedure. There are significant potential complications. Pedicle impaction osteotomy may alleviate those complications. Late complications such as nonunion often lead to further challenging surgery.

PURPOSE This work presents a case of extrinsic thoracic spinal cord compression related to the supine position and describes our approach from diagnosis to the technical therapeutic creation of a spinal protection shield. STUDY DESIGN One case of a patient suffering from extrinsic spinal cord compression syndrome is reported. PATIENT SAMPLE We report the case of a Coptic priest patient who, as a result of Pott disease sequelae, underwent several decompressive and stabilizing surgeries for major kyphoscoliosis. Consequently, he developed extrinsic thoracic spinal cord compression caused by the supine position. OUTCOME MEASURES After each instrumentation device removal, we noticed progressive severe paraparesis when the patient was supine. Imaging assessment confirmed spinal dynamic and intermittent compressions triggered by the supine position, which was facilitated by the exposure and vulnerability of the thoracic spine cord. METHODS We implanted a tailored titanium mesh spinal protection shield and a trapezius flap for spine coverage. This work presents the diagnostic aspects as well as several surgical technique options. RESULTS At the 6-year follow-up, the patient's neurologic conditions were significantly improved. We report neurologic improvements, no sphincter disorder, persistent spasticity, and lower limbs weakness not affecting full ambulation. CONCLUSIONS To our knowledge, no other case of spinal protection shield in compressions caused by the supine position have been studied. The surgical and technical management therefore remains innovative.

Tuttavia, questa chirurgia deve costituire l’ultima risorsa dopo un trattamento medico, salvo complicazioni neurologiche, anche se non vi è consenso sulle indicazioni. In effetti, anche se i risultati sono considerati molto buoni, le sequele operatorie non sempre sono favorevoli. Le ernie discali possono avere diverse localizzazioni: mediana, posterolaterale, intraforaminale ed extraforaminale. La strategia chirurgica deve essere adattata in funzione della topografia dell’ernia, dell’eventuale recidiva, dello stato del disco e dei piatti vertebrali adiacenti. Questo articolo tratta la discectomia per via posteriore mediana, la discectomia posterolaterale secondo Wiltse, le discectomie endoscopiche transforaminale e interlaminare, e la chirurgia di revisione discale. Le protesi lombari e le artrodesi non sono trattate in questo articolo.

La fracture périopératoire de patella après prélèvement d’un greffon os-tendon patellaire-os est une complication rare, qui peut altérer sérieusement le résultat fonctionnel final de la reconstruction du pivot central. Nous rapportons ici le cas d’une patiente présentant un syndrome fémoro-patellaire handicapant à trois ans d’une reconstruction du LCA par autogreffe os-tendon-os sous arthroscopie, en rapport avec un cal vicieux patellaire sur fracture sagittale peropératoire passée inaperçue. Nous présentons ici une prise en charge chirurgicale par ostéotomie patellaire ayant permis de corriger l’instabilité patellaire douloureuse iatrogène.

The purpose of this study was to determine morbidity and mortality of degenerative lumbar spine surgery in patients 80 years of age or older. A consecutive retrospective review evaluated 121 consecutive patients, who had undergone posterior decompression associated or not with lumbar instrumentation. The average age at the time of surgery was 83.2 ± 2.4 years. The study analyzed the comorbidities, the operative procedure and postoperative morbidity and mortality. Blood loss increased significantly with instrumentation (538 vs. 280 mL, p < 0.0001). The average operative time was 103 ± 38 min and increased significantly with instrumentation (131.2 vs. 84 min, p = 0.003), blood loss (p < 0.0001) and dural tears (p = 0.05). Dural tears occurred in 19 patients (15.7 %) and were associated significantly with previous lumbar surgery (33.3 vs. 12.4 %, p = 0.017) a...

Introduction L’esperance de vie n’est pas le seul critere de resultat apres des resections tumorales massives. La qualite de vie residuelle est egalement cruciale. L’indication de chirurgie majeure pour tumeur rachidienne doit prendre en compte le statut fonctionnel a long terme du patient, or seule une litterature limitee se penche sur la question. Patients et methodes Vingt-cinq patients vivants issus d’un groupe de 120 operes ont ete evalues. Tous furent operes par le meme chirurgien entre 1984 et 2007. Le suivi moyen est de 9 ans (intervalle : de 3 a 25 ans). L’âge moyen a l’operation etait de 49 ans. Les patients ont complete differents questionnaires fonctionnels et de qualite de vie : Oswestry Disability Index version 2 (ODI), Prolo, Karnofsky Index of Performance Status (KI), Eastern Cooperative Oncology Group Performance Status (ECOG), Short Form-36 Health Survey (SF-36) et EuroQoL-5 Dimensions (EQ5D). De plus, chaque patient a ete evalue cliniquement et radiographiquement. Des sous-groupes ont ete identifies en considerant le nombre de niveaux reseques et l’histologie. Leurs resultats au SF-36 ont ete compares avec ceux de la population generale francaise. Resultats En moyenne, le PCS (composante physique du SF-36) etait a 52,4, le MCS (composante psychique du SF-36) a 47,7, l’ODI a 18,2, le Prolo a 7, l’ECOG a 1 et le KI a 80 %. Les resections de trois niveaux sont associees aux moins bons resultats de qualite de vie mais, dans l’ensemble, les resultats etaient similaires aux donnees de la population generale francaise pour toutes les categories du SF-36. Conclusion Les indications appropriees de resection rachidienne massive donnent de bons resultats oncologiques et fonctionnels. Si c’est l’esperance de vie attendue qui justifie cette chirurgie agressive, la qualite de vie postoperatoire montre qu’elle peut egalement constituer un succes sur le plan fonctionnel. Niveau de preuve Niveau IV, etude clinique retrospective.
