Complex regional pain syndrome following spine surgery: clinical and prognostic implications.

BACKGROUND: Complex regional pain syndrome (CRPS) has been reported following spinal surgery, but its frequency after spinal surgery is unknown. The aim of this study was to determine the frequency of spinal surgery preceding CRPS and to examine these patients regarding the course of the disease and prognostic factors. METHODS: We examined 35 CRPS patients regarding the symptoms and signs of CRPS, the type of CRPS (I or II), the origin and grade of the disease, the type of surgeries prior to CRPS onset, the course of the disease, and the therapies following diagnosis of CRPS. RESULTS: In 6 patients, CRPS began during the postoperative course (lumbar spine surgery, n = 5; cervical spine surgery, n = 1). Four of these patients suffered from CRPS II. The course of the disease in the 6 patients was not different from that of patients with CRPS of other origins. First symptoms of CRPS could be observed 1-14 days after surgery. CONCLUSIONS: CRPS is a rare complication after spinal surgery, but spinal surgery precedes the onset of CRPS of the lower limb in almost one-third of the cases. The first typical symptoms of CRPS emerge within 2 weeks after spinal surgery.

[Rational use of blood cell products in orthopedics and traumatology]. / Rationaler Einsatz von Blutkonserven in Orthopädie und Traumatologie.

STUDY DESIGN: The risk of transmission of human immunodeficiency virus (HIV), hepatitis B and C viruses as well as the development of costs has changed the use of homologous blood cell products. METHODS: The present investigation shows the state of the art of blood salvage in orthopedic and elective trauma surgery. RESULTS: In this investigation the established methods such as controlled hypotension (spine surgery), arrest of blood supply (extremity surgery) and the following methods of autotransfusion have been examined: acute normovolemic hemodilution (ANH), intra- (Cell-Saver, Haemonetics Corp.) and postoperative autotransfusion, autologous donor plasmapheresis and autologous predeposit. CONCLUSIONS: Using this method it is possible to reduce homologous blood transfusions particularly in elective procedures such as orthopedic surgery and elective trauma surgery to a minimum.

Surgical treatment of the spine at the cervicothoracic junction: an illustrated review of a modified sternotomy approach with the description of tricks and pitfalls.

The surgical treatment of burst fracture, tumour or spondylitis remains a challenge with regard to the surgical approach to the anterior aspect of the cervicothoracic junction. Many vital structures including osseus, articular, vascular and nervous ones hinder the exposure. Fortunately, indications for surgery in this region are rare. However, when it becomes necessary for the surgeon to expose this region, it is useful to be prepared to approach it carefully. In this investigation the anatomy and exposure of the cervicothoracic junction by means of a sternotomy are described. An illustrated review of the sternotomy approach to the cervicothoracic junction with a description of 'tricks and pitfalls' is provided.

[Paralysis of the foot as the first symptom of a herniated thoracic disc]. / Plegie der Fussheber und Fusssenker als Erstsymptom von thorakalen Bandscheibenvorfällen.

Herniated thoracic discs are uncommon entities that are difficult to diagnose. They may be associated with a myriad of symptoms, which often delays diagnosis. In general dorsal pain that radiats around the chest or abdomen are found. In case of spinal cord compression signs of thoracal myelopathy are common. This paper describes a patient with a complete paralysis of the left foot as the first symptom of a herniated thoracic disc. After frustrated diagnostic of the lumbar spine, the exact neurological examination showed a sensible cut at the level of D6/7, the MR tomography diagnosed a herniated thoracic disc at the same level. Four months later he was presented again with a plegia of the left foot and a sensible cut at the level D5/6. The MR tomography showed a herniated disc at the level above the spondylodesis. The immediately performed transthoracic disc excision and fusion of D6/7 was followed by complete remission of the plegia and the sensible cut. Four months later we performed a rethoracotomy, disc excision and decompression with a spondylodesis D5/6. The procedure was again followed by complete remission. In case of paralysis of the lower extremities one has to consider a herniated thoracic disc.
