Complex injuries of the shoulder require differentiated management. Interestingly there is a relative lag of warranted information on this subject. Generally the different lesions are discussed separately. However it is not acceptable to simply add the standard diagnostic and therapeutic measures, because major tactic, strategic and rehabilitation incompatibilities could occur. Diagnostic and therapeutic difficulties are frequent for the following injuries: complex proximal humerus dislocation fractures, dislocation fractures with associated lesions of the rotator cuff, posterior dislocation fractures, peri- and intraarticular segmental fractures and fractures or dislocations associated with major neurovascular lesions. Increased awareness of the most relevant diagnostic and therapeutic aspects should contribute to optimize treatment protocols.
The management of narrowing spinal fragments in the operative treatment of spinal fractures remains an open question, in particular when the procedure is performed by a posterior approach. This article describes the use of intraoperative ultrasonography during spinal surgery. From 1990 to 1997, 116 spinal fractures were treated operatively at our clinic. Stabilization of the spine was achieved with the AO fixateur interne and the AO USS, respectively (Synthes, D-79224, Umkirch, Germany). For 60 cases who had a fractured posterior vertebral surface dislocated into the spinal canal, we used intraoperative ultrasonography to monitor the repositioning of the narrowing fragments. The patients underwent pre- and postoperative computed tomography scans (CT). In six cases, color-coded duplex sonography was performed intraoperatively to view the A. spinalis anterior. In 58 cases, the spinal canal and the fractured posterior surface of the vertebrae were visualized successfully. The sonographic image was inconclusive in two cases with severely damaged fragments. Identical findings were observed on the intraoperative ultrasound image after completion of repositioning and on the postoperative CT scan. In six cases, the A. spinalis anterior was viewed by color-coded duplex sonography with a different flow before and after fracture repositioning. Intraoperative ultrasound is a valuable means of monitoring the restoration of the spinal canal by a posterior approach. The method is easy to perform and can be repeated as often as required. Color-coded duplex sonography allows further visualization of the A. spinalis anterior.
