[Complications in surgical management of spinal injuries].

Operative treatment of spinal injuries requires an accurate surgical technique and biochemical know-how to avoid complications due to mistakes in device handling, operative technique, and indication. Device failures are caused by loosening of locking clamps or fracture of Schanz screws, followed by loss of angle stability and early loss of reduction. Maldisplacement of pedicle screws may involve irritation of neurovascular structures or loss of correction as well as insufficient transpedicular bone reduction and bone grafting. In burst fractures with destruction of the vertebral body and loose canal fragments, the posterior approach is less efficient than a combined procedure.

[Open fractures of the elbow joint].

Both in open and in closed elbow fractures, anatomical joint reconstruction and rigid internal fixation, which permit early initiation of motion, are essential for good joint function. However, in open distal intraarticular humerus fractures this is more difficult to achieve, owing to the high rate of comminuted types C 2 and C 3 fractures. In addition, the extensive soft tissue lesions often mean that physiotherapy cannot be started until later than would otherwise be desirable. This retrospective study shows that the functional results in 60 patients operated on for correction of open distal intraarticular humerus fractures were worse (1/3 "excellent/good", 2/3 "moderate/poor") than those in patients treated for closed fractures. Complications included superficial infection in 7 patients, osteitis in 11, late instability in 10, fatigue failure of the implants in 5, and non-union in 10 patients.

[Operative treatment of distal intra-articular humerus fractures; results of 412 follow-up cases (AO-collected statistics)].

Intraarticular fractures require a surgical therapy. The functional results are depending on the anatomical reconstruction of the joint surfaces and on early kinesitherapy. Remaining disabilities may be controlled in 2/3 of the cases to such an extent that no alterations are necessary in private or professional life. The overall result was very good in 23.8%, good in 36.0%, moderate in 22.3% and bad in 17.9%. These bad results are due to the rate of polytraumatized patients (18%) and the high rate of open comminuted fractures (27%).
