Case Reports
[Injury to the subclavian and vertebral arteries in childhood following blunt force trauma].
Injuries of great vessels, such as the subclavian or vertebral arteries in childhood are rare. More frequent and therefore better described are dissections of the vertebral artery, which frequently occur following low energy trauma. ⋯ Therapeutic anticoagulation is the therapy of choice to avoid possible ischemic insults. The therapeutic approach of injuries to the subclavian artery remains unclear and is in the focus of discussions.

Hamstring and patella tendons are usually used for anterior cruciate ligament (ACL) reconstruction and fixed with foreign material, partially executed far from the original point of insertion. Besides the biomechanical questions bone defects are a severe problem in cases of revision. We developed a biological method with diamond cutting instruments for graft fixation with bone dowels near the native insertion. The graft is tensioned and fixed in 120 degrees knee flexion and is self-adapting in extension. The technique has been used in a large number of cases during a prospective study with a follow-up of 10 years for patella tendon and 4 years for hamstring tendon grafts. In this investigation 124 patients with bone-patellar tendon-bone (BPTB) grafts showed an International Knee Documentation Committee (IKDC) score A/B in 87% after a mean follow-up of 9.6 years, a Lachman test (maximum side-to-side difference) of 1.38+/-0.93 mm and a negative pivot shift test in 91% of the cases. Of the 147 patients with hamstring tendon grafts 89% had an IKDC score A/B after a mean follow-up of 4.3 years, a Lachman test of 1.14+/-0.76 mm and no pivot shift in 90% of the cases. The Tegner activity score decreased by -1.8 in both groups. ⋯ This method allows a reliable biological press-fit fixation for every kind of graft near the original point of insertion, preventing bone defects, allowing early intensive rehabilitation and low costs.

The German DRG (diagnosis-related groups) system forms the basis for billing inpatient hospital services. It includes not only the case groups (G-DRGs), but also additional and innovation payments. This paper analyzes and evaluates the relevant developments of the G-DRG System 2010 for orthopedics and traumatology from the medical and classification perspectives. ⋯ For the first time since the introduction of the G-DRG system, the pure numerical changes at the level of DRGs themselves are so marginal that only part of the DRG users in the hospitals will register them. The changes implemented not only a high selectivity between complex and less complex scenarios, but partly also unintended and unjustified revaluation of less complex measures. The G-DRG system has gained complexity again. Especially the G-DRG allocation of spinal surgery and multiple surgical interventions of the upper and/or lower extremities have reached such a complexity that only a few DRG users can follow them.

Problems related to the use of interference screws for fixation of bone-patellar tendon-bone grafts for anterior cruciate ligament (ACL) replacement have led to increasing interest in press-fit techniques. Most of the described techniques use press-fit fixation on either the femoral or tibial side. Therefore an arthroscopic technique was developed which achieves bone-patellar tendon-bone graft fixation by press-fit on both sides without the need for supplemental fixation material. ⋯ The presented press-fit technique avoids all complications related to the use of interference screws. It achieves primary stable fixation of the bone-patellar tendon-bone graft thereby allowing early functional rehabilitation. However, fixation strength depends on bone quality and the arthroscopic procedure is demanding. The results showed reliable stabilization of the operated knees.

Case Reports
[Missed clavicle fracture, deep vein thrombosis following bicycle accident with head and chest trauma].
A 57-year-old patient suffered head and chest trauma following a bicycle accident. After 12 days in hospital with early mobilization the patient developed a deep vein thrombosis 5 days after being discharged and the family physician diagnosed a non-displaced clavicle fracture. ⋯ The expert opinion from the arbitration board determined that no health limitations had occurred as a result of the missed clavicle fracture. There were no indications for anticoagulation in accordance with the guidelines due to a lack of risk factors and the event was deemed unpreventable.
