Artrosis patelofemoral: tratamiento quirúrgico no protésico / Patellofemoral osteoarthritis. Non-prosthetic surgical treatment

La artrosis patelofemoral es una entidad clínica frecuente y muy incapacitante. Numerosos tratamientos han sido propuestos para el tratamiento quirúrgico de esta patología cuando fracasa el tratamiento ortopédico. Los hemos dividido en tratamientos quirúrgicos menores (liberación retináculo lateral- resección osteofito lateral y resección de la faceta lateral) y mayores (osteotomía de la TAT-cultivo de condrocitos- remplazos articulares). El objetivo de este trabajo es realizar una actualización de esta entidad clínica, y presentar una serie de casos mostrando la experiencia personal en el manejo de esta patología. Nivel de Evidencia: V

Patellofemoral osteoarthritis is a common and very disabling clinical entity. Several treatments have been proposed for the surgical treatment of this disease when the orthopedic one fails We’ve divided these treatments into minor surgery (lateral retinaculum release- laterally osteophyte resection and resection of the lateral facet) and major (osteotomy TAT-ACI- joint replacements). The aim of this work is an update of this clinical entity, and presents a series of cases showing personal experience in the management of this condition. Evidence Level: V

Atrapamiento del nervio ciático en el espacio subglúteo: tratamiento endoscópico / Deep gluteal syndrome. Endoscopic treatment

Se ha sugerido el término síndrome de glúteo profundo (deep gluteal syndrome) (SGP) para definir la compresión del nervio ciático en la región anatómica del espacio glúteo, o aquellas ciáticas no discogénicas con origen en esta región. Este síndrome tiene una alta prevalencia pero un bajo diagnóstico. Existen numerosas causas que pueden originar su afectación y compresión a nivel de dicho espacio. El uso rutinario de los test de evaluación, junto con una sospecha diagnóstica, determinará la incidencia real de este síndrome. La cirugía abierta ha sido descripta y utilizada como tratamiento. El tratamiento endoscópico es efectivo y disminuye el índice de morbilidad y eficacia en comparación con la cirugía abierta. El objetivo del trabajo es presentar una actualización de las características clínicas, test diagnósticos, métodos complementarios, causas y alternativas de tratamiento del SGP, haciendo hincapié en los detalles técnicos del procedimiento endoscópico.

The term Deep Gluteal Syndrome (DGS) has been suggested to define the compression of the sciatic nerve in the anatomical region of the gluteal space, or those ciatic non-discogenic pain with origin in this region. Pathology that is presented with a high prevalence, but at the moment underdiagnosed. There are numerous causes that can originate their affectation and compression at level of this space. The routine use of the evaluation test, together with a diagnostic suspicion, it will determine the real incidence of this problem. The open surgery has been described and used as treatment. The endoscopic treatment is effective and adds less morbidity and effectiveness in comparison with the open surgery. The objective of this article is to present an upgrade of the clinical features, diagnostic test, complementary methods, causes and alternative of treatment of the DGS, making stress in the surgical technique of the endoscopic release.

Endoscopic Anterior Release and Posterior Total Spondylectomy for Primary Tumors of Spine / 대한척추외과학회지

STUDY DESIGN: A retrospective study. OBJECTIVES: To introduce an endoscopic anterior release and posterior total spondylectomy, and the evaluation of its clinical efficacy. SUMMARY OF LITERATURE REVIEW: A total spondylectomy was introduced for the treatment of primary and metastatic tumors of the spine, with many authors having reported favorable clinical results with its use. Endoscopic surgery has been used for various spinal disorders, including disc diseases or scoliosis, and has been widely used as it offers a minimally invasive technique, with a small surgical incision and very few complications. MATERIAL AND METHODS: Three primary spinal tumor cases were reviewed. The first case was a patient with a Ewing's sarcoma of the sacrum; the second was a giant cell tumor of the sacrum and the last was a giant cell tumor of the T10 vertebra. An endoscopic anterior release was initially performed, including the ligation and release of blood vessels, and soft tissue release, using laparoscopies for the 2 sacral tumors and a thoracoscopy for the thoracic tumor. The total spondylectomy were performed via a posterior approach. In two cases, the one with the Ewing's sarcoma of sacrum and the other with the giant cell tumor of the T10 vertebra, the reconstructions were performed using strut allografts and instrumentations. The average follow-up period was 19 months. RESULTS: Intraoperatively, the endoscopic anterior release made it possible to successful finish the anterior releases, with minimal incisions and blood losses. It also allowed a safer and faster posterior total spondylectomy, without significant complication. At the last follow-up, all patients had favorable clinical results, with no local recurrence in any case or fusions in the two cases that had to undergo reconstruction. CONCLUSION: Endoscopic anterior release and a posterior total spondylectomy was a favorable surgical procedure for primary tumors of spine. It made possible the safe and efficient finish the anterior release and posterior total excision of the affected vertebrae, using small incisions and with no complications.

Change of Pillar Pain after Endoscopic Carpal Tunnel Release / 대한정형외과학회잡지

PURPOSE: Endoscopic carpal tunnel release has been reported to offer the advantages of reduced pain and complications, and to allow a rapid return to work. It was, therefore, introduced as an alternative to open carpal tunnel release. With this in mind, we analyzed changing pillar pain after endoscopic carpal tunnel release. MATERIALS AND METHODS: We analyzed 22 patients (35 cases) who were treated by endoscopic carpal tunnel release, and followed for over l year, from November 1999. RESULTS: According to Cseuz's criteria, 27 cases were excellent and 5 were good. Levine's Symptom Severity Scale improved from 35 preoperatively to 14 postoperatively. CONCLUSION: While endoscopic carpal tunnel release was confirmed to offer the advantages of reduced pain and palmar scarring, there seemed to be no difference in the clinical results compared with the open method. Therefore, endoscopic carpal tunnel release may be a useful method if it is done skillfully and carefully. However, even in the case of endoscopic release, pillar pain remains a problem. Long term results need to be examined to evaluate recurrence.

Endoscopic Release in Carpal Tunnel Syndrome / 대한정형외과학회잡지

Carpal tunnel syndrome is known as the most common peripheral nerve entrapment neuropathy which results from compression of the median nerve within the carpal tunnel. Recently, endoscopic carpal tunnel release was introduced as an alternative of open carpal tunnel release. The purpose of this study is to find out the clinical usefulness of endoscopic carpal tunnel release through analyzing results of symptom, physical sign and E.M.G. finding. We analyzed 20 patients (29 cases) who had been treated by endoscopic carpal tunnel release, and followed up over 6 mos at Department of Orthopedic Surgery, Bongseng Memorial Hospital from August 1994 to December 1996. The results were excellent or good in 27 cases (93%) in Cseuz criteria, poor in only 1 case. Grip strength recovered to preoperative strength level in 28 cases (96.6%) at 3 mos postoperatively. The EMG checked postoperatively demonstrated improvement in both sensory and motor function. In conclusion, although endoscopic carpal tunnel release is a technically demanding procedure and the learning curve in steep, it has the advantage of lesser palmar scarring, lesser ulnar pillar pain, rapid and complete return of strength and to work. Therefore, endoscopic carpal tunnel release can be a good method in the treatment of carpal tunnel syndrome.
