[Conventional and semi-open kyphoplasty].

Kyphoplasty is a young method which was developed for the minimally invasive augmentation of osteoporotic vertebral fractures. In contrast to vertebroplasty, the kyphoplasty technique allows an age-dependent fracture reduction through the inflation of a special balloon in the fractured cancellous bone of the vertebral body. The cancellous bone of the fracture zone is compressed by the balloon, so that a cavity remains in the vertebral body after removing the balloon, which is filled with highly viscous augmentation material. The reduced risk of serious complications, for example epidural leakage of augmentation material, justifies progressively expanding the indications for this technique to traumatic fractures with involvement of the posterior vertebral wall and neoplastic vertebral collapse due to osteolytic metastasis. Besides the indications for the conventional percutaneous approaches, the microsurgical interlaminary approach allows the use of kyphoplasty in more complex fractures involving compression of the neural structures. Kyphoplasty induces swift pain relief and allows rapid mobilisation of patients due to the immediate stabilisation of the affected vertebral bodies. Apart from the operative intervention, the medical treatment of the primary disease and the rehabilitation of the individual patient should be optimised through an interdisciplinary approach.

[Psoas abscess after anterior spinal fusion].

We present 3 cases of secondary psoas abscess after anterior spinal fusion. Psoas abscess is still a rare clinical entity. It is often associated with unspecific symptomatology and may present as late infection. A high index of suspicion is required for early diagnosis and treatment. Computed tomography is the imaging technology of choice. Treatment includes open abscess drainage and antibiotic therapy. In secondary psoas abscess causative treatment of the primary infection focus is essential. For psoas abscess after anterior spondylodesis this includes treatment of a deep wound infection. Predisposing factors for postoperative infection are large implants, bone grafting, long operating times, previous spinal surgery, immunodeficiency and metabolic disorders. Usually several operations are necessary to eradicate infection. As long as stability is guaranteed, implant materials should be removed. Continuing antibiotic therapy for 2-3 weeks after normalization of infectious parameters is suggested. Delayed therapy results in an increase of the morbidity and mortality of psoas abscess.

[Mechanical testing of implant properties of thoracoscopic implantation of ventral spinal stabilizing systems. Comparative study with the ISO/DIS 12189-2 corpectomy model and an improved synthetic model].

A new modular anterior fixation system MACS TL (modular anterior construct system for the thoracic and lumbar spine) has been developed for use in thoracoscopic spondylodesis. This system demonstrates high angular stability and meets the surgical requirements for an endoscopic approach. The objective of the current study was fatigue testing of the MACS TL implant system using a corpectomy model according to ISO/DIS 12189-2 and a synthetic model recently developed by Kotani et al. [6]. The MACS TL system demonstrated good mechanical properties with a high stiffness compared to the published data reviewed. The importance of dynamic testing in a corpectomy model has been demonstrated by comparing the MACS TL plate system with an early prototype, which has not yet been clinically evaluated. The corpectomy model according to Kotani et al. offers an interesting alternative to the ISO/DIS 12189-2 test method for asymmetrically designed and antero-laterally positioned spinal implants due to the unconstrained ball joint.

[Development and clinical application of a thoracoscopy implantable plate frame for treatment of thoracolumbar fractures and instabilities].

The evolution of endoscopic spinal approaches and the associated possibilities for stabilization of the anterior column demands a new generation of spinal implants. Of particular interest is the possibility to implant using an endoscopic approach and the ability to achieve real angular stability so that for a suitable injury pattern an exclusively anterior procedure can be carried out. Since November 1999, a new type of anterior plate, MACS TL, developed to meet minimally invasive clinical requirements, has been used in the Berufsgenossenschaftliche Unfallklinik in Murnau, Germany for treating the mid and lower thoracic and lumbar region. The following reports on the results of the first 100 procedures carried out over a period of 15 months, of which 93% were performed endoscopically. The results convey a trend toward anterior endoscopic treatment of injuries of the anterior column using an implant with angular stability. The results now available on healing after fusion indicate the favorable influence of the stability provided by the implants on the bone-healing rate.

[Thoracoscopy-guided management of the "anterior column". Methods and results].

Anterior thoracoscopic interbody stabilization and fusion was performed in 163 patients. Lesions treated were located between T4 and L3, most frequently occurring at T12/ L2. Operative time decreased dramatically as experience was gained with the procedure. 2 patients early in the series successfully were converted to an open procedure. One positioning related pressure harm on the thoracodorsal nerve and one irritation of the L1 root at the entrance site were both transitory. Postoperative control by X-ray and CTscan showed correct positioning of the bone graft, as well as the fixation device in all patients. Our experience with this minimally invasive procedure demonstrated the feasibility of the method. Major advantages compared to the open procedure are reduced morbidity of the approach, postoperative pain reduction, early recovery of function and shortened hospital stay.

[Endoscopically controlled division of the diaphragm. A minimally invasive approach to ventral management of thoracolumbar fractures of the spine].

On 90 patients with 93 unstable fractures of the thoracic spine and the thoracolumbar junction we treated by a minimal invasive procedure between may 1996 and april 1998, in 46 patients an endoscopic splitting of the diaphragm was performed. The diaphragma was dissected at its attachment at the spine and the adjoining costal base. After partial corporectomy and discectomy, a tricortical bone graft has been inserted. An additional stabilization was done by using a plate and screw system. The incision of the diaphragm was closed by suturing or using an universal endostapler. Controlling the postoperative results a complete closure of the incision was documented by X-ray and CT-scan. There was no conversion to the open procedure or postoperative infection. Splitting the diaphragma opens also the thoracolumbar junction to a minimal invasive treatment and stabilization of fractures.

[Minimally invasive ventral spondylodesis in injuries to the thoracic and lumbar spine].

Thirty-eight patients with 40 fractures of the thoracic spine and the thoracolumbar junction were treated by a minimally invasive procedure, which includes partial corporectomy, the interposition of a tricortical bone graft and anterior stabilization by plate spondylodesis under thoracoscopic control. For 36 patients the operation was successfully performed in a complete thoracoscopic way; in 2 patients conversion to an open technique was necessary. Two postoperative complications such as a reversible lesion of the thoracodorsalis nerve and a transient irritation of nerve root L1 on the approach side were encountered. Postoperative control by X-ray and CT scan showed correct positioning of the bone graft, as well as the fixation device in all patients. Our experience with this minimally invasive stabilizing procedure for injuries of the thoracic spine and the thoracolumbar junction demonstrated the feasibility of the method. Compared to the open method the benefit of minimally invasive surgery included postoperative pain reduction, shorter hospitalization, early recovery of function and reduced morbidity of the operative approach.
