    Notes: [Auszug] In photosynthesis, the harvesting of solar energy and its subsequent conversion into a stable charge separation are dependent upon an interconnected macromolecular network of membrane-associated chlorophyll–protein complexes. Although the detailed structure of each complex has been ...

    Description / Table of Contents: Zusammenfassung. Anhand des Falls einer 30 jährigen Patientin, die im Rahmen eines Autounfalls eine drittgradig offene Oberschenkelfraktur erlitten hat, wird der „reversed“ oder distal gestielte M.-biceps-femoris-Lappen zur Defektdeckung am antero-lateralen, distalen Oberschenkel dargestellt. Zum Zeitpunkt der Verlegung in die Unfallchirurgische Klinik der Universität Bonn, 14 Wochen nach dem Unfall, hatte sich u. a. aufgrund eines Weichteildefekts und einer instabilen Osteosynthese eine posttraumatische Osteitis entwickelt. Nach Infektberuhigung durch die Materialentfernung, Anlage eines Fixateur externe sowie mehrere Débridements wurde zweizeitig ein M.-biceps-femoris-Lappentransfer, in Verbindung mit einer inneren Osteosynthese, durchgeführt. Dank der Defektdeckung und Durchblutungsförderung im Frakturareal durch den M.-biceps-femoris-Lappen kam es zu einer Ausheilung der Fraktur. Die Operationstechnik wird dargestellt.
    Notes: Summary. We report the case of a 30-year-old female patient, who had suffered a grade III open femur fracture in a motor vehicle accident 14 weeks prior to being transferred to the trauma department of the University Hospital in Bonn. Upon admission to our unit, posttraumatic osteitis, an unstable fracture following compression plating, and a soft tissue defect of the anterolateral distal thigh were discovered. Following removal of the hardware and stabilization of the fracture with external fixation, the infection was brought under control. Because the patient refused the time-consuming segmental transport utilizing the callus distraction technique, local muscle transfer and shortening of the femur were carried out. The most lateral of the hamstring muscles, the biceps femoris, was used as a distally based muscle flap utilizing a delay technique. With the help of a reversed biceps femoris flap, the soft tissue defect was closed, the infection subsided and the fracture healed. The surgical technique is outlined.

    Description / Table of Contents: Zusammenfassung Vorgestellt wird die Fokussanierung einer chronisch sequestrierenden Talusosteomyelitis durch die tibiokalkaneonavikulokuboidale (TCNC-)Arthrodese nach Talusresektion und simultaner Unterschenkelverlängerung mittels Ilizarov-Ringfixateur. Eine neue Technik wird anhand eines Fallbeispiels dargestellt. Hiermit konnte eine dauerhafte Infektsanierung sowie vollbelastbare untere Extremität erzielt werden und somit die drohende Amputation vermieden werden.
    Notes: Summary A technique utilizing the Ilizarov ring fixator to stabilize a tibio-calcaneo-naviculo-cuboideal arthrodesis following talus resection is introduced. The advantages of this method will be demonstrated with the help of a case history. The described method permits early weight bearing, while supplying stability and compression of the fusion, thereby avoiding further loss of bone stock, while reducing the risk of thromboembolic complications. The Ilizarov ring fixator construction allows for the combination of the fusion with the correction of a preexisting or ensueing leg length discrepancy.

    Notes: Abstract As part of a retrospective study, 76 patients with acute tears of the anterior cruciate ligament who underwent reinsertion and augmentation with the semitendinosus tendon were examined. The follow-up took place on average 4.5 years (range 3–7 years) after surgery. A decreased range of motion upon comparison with the uninjured opposite side was seen in 43 patients. The Lachman test revealed a grade 1 instability in 42 patients, grade 2 in 17 and grade 3 in 2, while 15 patients had a negative test result. The average Lysholm score was 92 points and the Tegner activity score had an average of 7.1 points. KT-1000 measurements showed an identical degree of anterior translation for both knees at 89 N in 25 individuals. The analysis revealed a difference of 2 mm in 15 patients, 4 mm in 19, 6 mm in 15 and greater than 6 mm in 2. The radiographic follow-up examination revealed a deterioration of the degenerative change of 1 deg in 17 patients and 2 deg in 4 patients. Isometric testing showed no loss in flexion strength of the operated knee joints compared to the healthy opposite side. The ratio between flexion and extension strength was also identical for both knees. The reinsertion and augmentation with a single strand of semitendinosus tendon is not, as this study demonstrates, the appropriate reconstructive technique for the majority of ACL tears.

    Notes: Abstract The results of a follow-up evaluation of open intra-articular calcaneal fractures are presented. A modified Merle d’Aubigné functional score and Zwipp radiographic score were used. A retrospective analysis of 35 patients with 36 open intra-articular fractures represents the basis of the study. At the time of follow-up examination (on average 44 months after the injury), 5 amputations of the affected extremity and 4 ankle arthrodeses had been carried out. The 23 patients still able to bear weight on the affected hindfoot and possessing a functional ankle joint were radiographically and functionally evaluated. No excellent results were documented. Only 6 good functional and 2 good radiographic outcomes were noted. In 17 instances, a poor functional or radiographic score was given. Devastating results were seen in the course of treatment of third-degree open joint depression or comminuted intra-articular fractures (n = 15): 9 cases of osteomyelitis, 5 amputations, 1 partial calcanectomy, 1 arthrodesis. An open reduction as part of the primary treatment (n = 6) led to local complications in all instances. The most favorable results were seen after nonoperative fracture management: complication-free course of treatment in 4 of 11 patients. All workmen’s injuries led to a permanent disability, and these patients received compensation. The treatment and salvage of the soft-tissue envelope should be paramount in all therapeutic decisions. The fracture treatment must not further jeopardize these tissues. An aggressive operative treatment of local complications, including arthrodesis or amputation, is recommended.

    Notes: Abstract During the time period from May 1990 to December 1992, a total of 75 tibia fractures were treated in the Department of Traumatology at the University of Bonn. Thirtyeight patients with 40 tibial fractures were managed according to a regimen including primary stabilization, usually using external fixation, soft tissue reconstruction and delayed open reduction and internal fixation using an AO compression plate. The majority of the patients had been involved in motor vehicle accidents, leading to multiple injuries in 24 instances. An open fracture was seen 18 times. The 20% complication rate is comparable to the reports following intramedullary stabilization. Only one infection, following a grade 2 open fracture, was seen after the definitive stabilization. Bony union was achieved after 15.7 weeks. In light of the complications associated with intramedullary nailing, such as fat or air embolism, heterotopic ossification and non- or malunions, use of the tibial plate does not offer just logistic advantages, but is a viable alternative for delayed stabilization of tibial fractures. No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article. No funds were received in support of this study.
