Currently there are few data available regarding the application and efficacy of computer-assisted procedures in the sacral spine. In order to optimize and standardize this procedure, a controlled experimental investigation has been performed. The aim of the study is to systematically assess the efficacy of a novel three-dimensional image intensifier used for navigated transiliac screw insertion into the first sacral vertebra. Screws were inserted iliosacrally into the first sacral vertebra of preserved human cadaver specimens. The instrument navigated procedure was performed with the "Siremobil Iso-C(3D) " (Siemens Medical Solutions) and the "Navigation System" by Stryker. The accuracy and quality of the imaging procedure as well as the fluoroscopic exposure times were measured. These results were compared to three control groups (CT-based navigation, C-arm navigation, and fluoroscopic guidance). In each group a total amount of 20 screws was implanted. Screw position was postoperatively assessed by Iso-C(3D) or CT-scan. The navigated procedure using the Iso-C(3D) provided good feasibility characteristics without requiring a specific matching process. It revealed the shortest procedure time of all navigated procedures and significantly decreased fluoroscopic time compared to C-arm navigation and fluoroscopic guidance. Furthermore, Iso-C(3D) navigation showed no screw malposition and was in this regard superior to C-arm navigated and fluoroscopic guided procedures. The quality of imaging was sufficient for accurate placement, but did not share the high-resolution level of CT-based navigation. These findings indicate that application of the Iso-C(3D) for navigated transiliac screw insertion into S1 can be recommended as a feasible and safe technique, enabling the surgeon to reduce procedure and fluoroscopic time. Further progress in improving the quality of the Iso-C(3D) image should be attempted.

Public Health, Environmental and Occupational Health ,Emergency Medicine - Abstract
Standardisierte Konzepte zur Prophylaxe posttraumatischer Infekte sind eine Conditio sine qua non in der Unfallchirurgie. Eine wirksame Infektionsprophylaxe muss mit dem richtigen Timing bei der Planung und Durchfuhrung einer operativen Masnahme beginnen und den gesamten Behandlungsverlauf als eine wesentliche Zielgrose mitbestimmen. Sie besteht nicht nur aus der Beachtung von Hygienevorschriften und Empfehlungen zur perioperativen Antibiotikaprophylaxe oder der Auswahl geeigneter Operationstechniken und Implantate, sondern basiert im Wesentlichen auf der personlichen Disziplin aller in den operativen Prozess eingebundenen Personen. In diesem Sinn wird die Prophylaxe posttraumatischer Infekte zu einem elementaren Grundstein der Qualitatssicherung, der durch vermeintliche Modernisierungsmasnahmen im Gesundheitswesen nicht gefahrdet werden darf.

Public Health, Environmental and Occupational Health ,Emergency Medicine - Abstract
Knochenersatzmaterialien haben in den letzten Jahren einen festen Platz im klinischen Alltag des Orthopaden und Unfallchirurgen eingenommen. Fur die knocherne Defektbehandlung vor allem bei alteren osteoporotischen Patienten sind die verfugbaren Substanzen sehr hilfreich. Das langfristig groste Entwicklungspotential wird augenblicklich den resorbierbaren Materialien zugeschrieben. Hier sind es vor allem die resorbierbaren Kalziumphosphatzemente, die im derzeitigen Mittelpunkt des klinisch/experimentellen Interesses stehen. Durch ihre Viskositat konnen mit den Zementen Defekte unterschiedlicher Form und Grose vollstandig aufgefullt werden. Die minimal invasive Applikation uber Stichinzisionen unter radiologischer Kontrolle ist moglich, wodurch die Zugangsmorbiditat in vielen Fallen in denen die Behandlung eines knochernen Defektes notwendig ist reduziert werden kann. Die Kombination mit einer stabilen Osteosynthese ist jedoch haufig erforderlich. Die Substanzen werden vollstandig in das biologische Konstrukt Knochen integriert und sind dem physiologischen Remodelingprozes unterworfen, d. h. die Materialien werden durch Osteoklasten resorbiert und durch neuen Knochen ersetzt. Diese Eigenschaft der Kalziumphosphatzemente ermoglicht es, das eigentliche Knochenersatzmaterial mit Medikamenten und/oder Wachstumsfaktoren zu vermischen und eine kontrollierte Freisetzung der Substanzen aus dem System zu erreichen. Zu berucksichtigen ist hierbei, dass die Resorption der kalziumhaltigen Zemente abhangig ist von ihrem Implantationsort (anatomische Lokalisation) und praktisch nie vollstandig geschieht. In wie weit auch diaphysare Defekt mit Hilfe von Kalziumphosphatzementen sicher uberbruckt werden konnen mussen weitere experimentelle Untersuchungen belegen. Die biologische Wertigkeit im Vergleich zu autogenem Knochen kann nur durch—noch immer fehlende—kontrollierte klinische Studien bestimmt werden.

The application of autogenous bone grafts represents the golden standard for reconstruction of the load-bearing anterior column in the thoracolumbar spine. However, the osseous integration of the implanted grafts is demanding and delayed union or pseudarthrosis may occur. There are no standardized data available yet indicating the further course in such cases. The aim of this study was to evaluate the incorporation of endoscopically applied grafts and to develop therapeutic strategies for delayed or non-fusions. Twenty patients suffering from unstable injuries of the thoracolumbar spine were studied in a prospective clinical trial. After primary dorsal stabilization, the anterior column was thoracoscopically reconstructed with an autogenous iliac crest graft and a fixed-angle implant (MACS). The osseous integration of the bone grafts was detected by MSCT 1 year postoperatively. Complete integration of the transplanted bone grafts was observed in only 65% of the cases. In 25% partial integration was detected and in two cases a fracture of the transplanted iliac crest graft occurred. Despite the incomplete integration of the bone grafts, the further course without surgical intervention revealed no clinical or radiological evidence of a concomitant implant loosening or a relevant secondary loss of correction. Similar to the open technique, endoscopic reconstruction of the anterior column with autogenous bone grafts may lead to disadvantageous results concerning the integration and healing of the applied bone grafts. Decision making in such cases depends on the individual clinical and radiological findings (i.e., evidence of implant loosening and concomitant loss of correction).

The treatment of osseous defects is widely established in the elderly. The number of positive reports on the successful application of bovine as well as coralline hydroxyapatite ceramics has continuously increased during the last few years. In trauma surgery hydroxyapatite ceramics are most commonly applied in metaphyseal defects evoked by traumatic fractures of the long bones. The bovine and coralline materials applied are biocompatible and exhibit an interconnecting porous system. Good osteoconductive properties of such materials have repeatedly been demonstrated. Due to possible harmful effects caused by abrasion of the material, intra-articular application should be strictly avoided. Biological degradation of the materials does not occur even during long-term follow-up. The application of hydroxyapatite ceramics was introduced at our institution in 1992. Since then, no adverse events have been observed and only a few relevant complications were described in the literature. We report on a patient revealing a mechanical failure of a bovine hydroxyapatite (Endobon) 7.5 years after implantation into a metaphyseal defect of the proximal tibia caused by a traumatic fracture.

Local muscle flaps for covering pretibial defects have been widely replaced due to the establishment of microsurgical procedures. The intention of the following study is to examine the results of soft tissue covering using local muscle flaps and to find out if its application is still indicated. At our level 1 trauma center 21 patients with III B open tibial fractures were treated with a local muscle flap to repair the soft tissue injury in the proximal and medial part of the lower leg. At the late follow-up after the average of 29 months all soft tissue defects and fractures were healed. Except of slight swelling under full weight stress no obstruction of blood circulation could be verified. 14 patients rated their functional outcome as good to excellent. In view of our results we consider local muscle flaps a suitable alternative to the free myoplasty for situations in which a more elaborate surgery is not feasible in due time, e. g. patients with acute brain edema, organ failure or lack of compliance.

The aim of the procedure is to visualize the proximal pouch of the DRUJ, the joint surfaces of the sigmoid notch and the ulnar head, the convexity of the ulnar head and the proximal ulnar side surface of the triangular fibrocartilage complex (TFCC).Arthroscopy of the distal radioulnar joint is applied for the evaluation of joint pathologies in ulnar-sided wrist pain, especially in cases without diagnostic findings in standard X‑rays and MRIs and arthroscopically assisted procedures.In vertical extension, two portals of the wrist are created on the dorsal side of the DRUJ between the extensor digiti minimi and extensor carpi ulnaris tendons. By insertion of a small joint arthroscope via these portals visualization of the ulnar head, the sigmoid notch, the proximal pouch of the DRUJ and the proximal surface of the TFCC is accomplished.Arthroscopy of the DRUJ is a rarely and not routinely performed procedure for the diagnosis and therapy of ulnar-sided wrist pain. It is technical demanding with a flat learning curve and anatomy-related obstacles. A complete view of the joint is not always accessible. Rare complications are injuries of the extensor digiti minimi tendon, as well as contusion or sectioning of the transverse branch of the dorsal branch of the ulnar nerve. In distinct cases, this procedure offers important additional information about the distal radioulnar joint. The procedure is especially valuable for the detection of proximal TFCC injuries that are missed otherwise.OPERATIONSZIEL: Ziel des Verfahrens ist die Inspektion des unteren Rezessus des distalen Radioulnargelenks (DRUG), der Gelenkflächen der Incisura radii und des Ellenkopfes, der Kuppe des Ellenkopfes und der proximalen Oberfläche des Discus triangularis (TFCC).Die Arthroskopie des distalen Radioulnargelenks dient zur Feststellung pathologischer Veränderungen bei ulnarseitigem Handgelenkschmerz, insbesondere bei negativen Befunden in der konventionellen Röntgendiagnostik und MRT-Diagnostik sowie der Durchführung arthroskopisch gestützter Verfahren.In Vertikalextension des Handgelenks werden zwei Portale auf der Streckseite des DRUG zwischen den Sehnen des M. extensor digiti minimi und M. extensor carpi ulnaris angelegt. Durch Einbringen einer Arthroskopieoptik für kleine Gelenke erfolgt die Inspektion des Ulnakopfes, der Incisura radii, des unteren Gelenkrezessus des DRUG sowie der proximalen Fläche und der Insertionsstellen des TFCC.Die Arthroskopie des distalen Radioulnargelenks ist ein seltenes und nicht routinemäßig eingesetztes Verfahren zur Abklärung und Behandlung von ulnokarpalen Schmerzen. Es ist technisch anspruchsvoll, mit einer flachen Lernkurve und anatomiebedingten Schwierigkeiten. Eine vollständige Übersicht über das Gelenk lässt sich nicht immer gewinnen. Seltene Komplikationsmöglichkeiten sind Verletzungen der Extensor-digit-minimi-Sehne sowie Quetschung oder Durchtrennung des Ramus transversus des Ramus dorsalis nervi ulnaris. Die Methode ist besonders wertvoll zur Feststellung proximaler TFCC-Läsionen, die ansonsten übersehen werden.

Injuries of the proximal interphalangeal joint (PIP joint) are common. They are frequently underestimated by patients and initial treating physicians, leading to unfavorable outcomes. Basic treatment includes meticulous clinical and radiological diagnosis as well as anatomical and biomechanical knowledge of the PIP joint.In avulsions of the collateral ligaments and the palmar plate with or without involvement of bone, nonoperative treatment is preferred. Operative stabilization is reserved for large displaced bony fragments or complex instabilities. In central slip avulsion or rupture, osseous refixation, suture, or reconstruction is common and nonoperative treatment is limited to special situations like minimally displaced avulsions. In basal fractures of the middle phalanx, elimination of joint subluxation and restoration of joint stability are priority. If the fragments are too small for fixation with standard implants, therapeutic alternatives include refixation of the palmar plate, dynamic distraction fixation, percutaneous stuffing, or replacement by a hemihamate autograft. Early motion is initiated regardless of the treatment regime. Undertreatment leads to persistent swelling, instability, and limited range of motion, which are difficult to treat. Contributing factors are unnecessary immobilization, immobilization in more than 20° flexion or transfixation by K-wires. For residual limitations, nonoperative treatment with physiotherapists and splinting is first choice. Operative treatment is reserved for persistent flexion/extension contractures persisting for more than 6 months, as well as reconstructions in boutonniere and swan neck deformity and salvage procedures for destroyed joints.

Besides the use of autologous bone grafting several osteoconductive and osteoinductive methods have been reported to improve bone healing. However, persistent non-union occurs in a considerable number of cases and compromised angiogenesis is suspected to impede bone regeneration. Hyperbaric oxygen therapy (HBO) improves angiogenesis. This study evaluates the effects of HBO on bone defects treated with autologous bone grafting in a bone defect model in rabbits. Twenty-four New-Zealand White Rabbits were subjected to a unilateral critical sized diaphyseal radius bone defect and treated with autologous cancellous bone transplantation. The study groups were exposed to an additional HBO treatment regimen. Bone regeneration was evaluated radiologically and histologically at 3 and 6 weeks, angiogenesis was assessed by immunohistochemistry at three and six weeks. The additional administration of HBO resulted in a significantly increased new bone formation and angiogenesis compared to the sole treatment with autologous bone grafting. These results were apparent after three and six weeks of treatment. The addition of HBO therapy to autologous bone grafts leads to significantly improved bone regeneration. The increase in angiogenesis observed could play a crucial role for the results observed.

Secondary fracture displacement before osseous consolidation of distal radius fractures in children occasionally leads to restricted forearm rotation. So far, there is no consistent treatment recommendation to correct this complication. We report on 5 children with an age of 8-13 years (mean age 12.3 years, 4 boys, 1 girl) with secondary displaced distal radius fractures and high functional deficits in forearm rotation (mean ROM for pro-/supination 70-0-30°) after osseous consolidation. We performed corrective osteotomies of the distal radius using a palmar approach after a mean of 38 days. Stabilisation was achieved with a fixed-angle plate system. At the final follow-up examination (mean 9 months) the forearm rotation was normal. No complications were observed. We consider corrective osteotomies of the distal radius in children with deficits of forearm rotation to be a possible strategy. Early corrective osteotomies can lead to a predictable increase of function through reestablishing normal articulation.

Es wird uber drei Patienten mit verschiedenen Verlaufsformen der insgesamt seltenen, primar chronischen Osteomyelitis berichtet. Sowohl die plasmazellulare als auch die sklerosierende Osteomyelitis bereiteten dabei wenig diagnostische Schwierigkeiten und konnten im Falle der beiden jugendlichen Patienten rechtzeitig therapiert werden. Heimtuckischer verlief demgegenuber der hier beschriebene Fall eines Brodie-Abszesses im Schienbeinkopf eines Vierzigjahrigen. Der Patient wanderte von Arzt zu Arzt, ohne das eine Klarung seiner Schmerzen im Kniegelenk erreicht werden konnte, bis schlieslich der nicht entdeckte Abszes in das Kniegelenk einbrach und durch das folgende Kniegelenkempyem zur operativen Klarung des Befundes fuhrte. Kurzfristige Rontgenkontrollen oder eine kernspintomographische Untersuchung hatten diesen Verlauf vermeiden und die Diagnose eines Brodie-Abszesses rechtzeitig stellen lassen konnen.

BACKGROUND/GOAL: Despite the fact that corrective osteotomy for malunited distal radius fractures is widely accepted, the optimal timing is still a matter of controversy. The presented study compares the clinical and radiological results of early vs. late corrective osteotomy at the distal radius to evaluate the influence of timing.We prospectively studied 34 consecutive patients with extraarticular malaligned fractures of the distal end of the radius who underwent corrective osteotomy. Early correction was performed in 14 patients (10 -women and 4 men with an average age of 48±18 years) at an average of 8±3 weeks (range, 3-13) after the injury, late correction in 20 patients (16 women and 4 men, average age of 54±19 years) at an average of 52±46 weeks (range, 24-229) -after the injury. The demographic data of the groups were statistically identical. Preoperatively and at the recent follow-up the range of motion of the wrist (ROM) and grip strength were recorded as well as pain at rest and activity (visual analogue scale), DASH score and radiological data. A conclusive evaluation was performed by the modified Mayo wrist score for the recent follow-up after 24±10 (6-44) (early correction) vs. 21±10 (8-56) (late correction) months.All osteotomies healed uneventfully. Early corrections required significantly less bone-grafting. The comparison of the pre- and postoperative data in the early corrrection group showed an improvement of all parameters, that was significant in four parameters. The comparison of the pre- and postoperative data in the late correction group showed an improvement of all parameters, that was significant in 5 parameters. The comparison of the postoperative data revealed nearly identical results in both groups for all parameters including the modified Mayo wrist score.The general improvement stresses the value of both, early and late reconstruction. Although no statistical difference was detectable early corrective osteotomy seems to be recommendable in early presenting patients, in order to avoid bone-grafting. In later presenting cases we recommend observation and return after 6 months in the case of persistent pain or disability. Nevertheless, the time choice of corrective osteotomy remains an individual decision in all patients.

Squamous cell carcinoma is the most common maligne primary tumour of the hand. It is almost always located on the dorsum of the hand, an occurrence in the palm is very rare. Usually these tumours are recognised early because of their clinical presentation and visible location. We report on a case in which the patient presented in our hospital only due to a massive mechanical impairment of his hand function through an oversized squamous cell carcinoma. On the basis of this case the therapeutic algorithm for large squamous cell carcinoma in the palm is illustrated and discussed.

Due to the heterogeneity of severely injured patients (multiple trauma) it is difficult to assign them to homogeneic diagnosis-related groups (DRG). In recent years this has led to a systematic underfunding in the German reimbursement system (G-DRG) for cases of multiply injured patients. This project aimed to improve the reimbursement by modifying the case allocation algorithms of multiply injured patients within the G-DRG system.A retrospective analysis of standardized G-DRG data according to §21 of the Hospital Reimbursement Act (§ 21 KHEntgG) including case-related cost data from 3,362 critically injured patients from 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals was carried out. For 1,241 cases complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of multiply injured patients within the G-DRG system. Analysis of coding and grouping, performance of case allocation and the homogeneity of costs in the G-DRG versions 2008-2012 was carried out.The results showed systematic underfunding of trauma patients in the G-DRG version 2008 but adequate cost covering in the majority of cases with the G-DRG versions 2011 and 2012. Cost coverage was foundfor multiply injured patients from the clinical viewpoint who were identified as multiple trauma by the G-DRG system. Some of the overfunded trauma patients had high intensive care costs. Also there was underfunding for multiple injured patients not identified as such in the G-DRG system.Specific modifications of the G-DRG allocation structures could increase the appropriateness of reimbursement of multiply injured patients. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical specialist societies.

The aim is correction of claw deformity of the fingers by intrinsic paralysis.Indications are claw deformity of fingers caused by palsy or functional loss of the interosseus or lumbrical muscles as far as the function of the superficial and deep flexors of the finger is intact.Contraindications are loss or paralysis of finger flexors supplied by the median nerve, fixed extension or flexion contracture of the finger joints, osteoarthritis and other malfunctions of the finger joints, no active flexion and extension of the interphalangeal joints due to compromised tendon gliding. Relative: Upper ulnar nerve palsy with functional loss of the deep flexor of the small and ring finger and possibly of the middle finger.The operation technique involves detachment of the flexor digitorum superficialis IV tendon (FDS IV) distal to Camper's chiasm, division of the tendon into separate strips, interweaving of each tendon strip into the proximal part of the A2 pulley of the affected fingers. In cases of claw deformity of all fingers it may be advantageous to apply the superficial flexor tendon of the long finger in addition to the FDS IV tendon as otherwise the FDS IV tendon has to be divided into four strips resulting in relatively thin tendon strips. If the FDS III and IV tendons are applied, the two strips of the FDS IV tendon are used for lassoplasty of the small and ring fingers and the FDS III tendon for lassoplasty of the middle and index fingers.Postoperative management includes immobilization of the operated fingers by a dorsoulnar forearm plaster cast including the metacarpophalangeal joints which are flexed to 70°. After 2 weeks replacement of the cast by a thermoplastic splint for another 4 weeks. During the whole period exercises for the finger and thumb should be carried out.From April 2003 to June 2012 a total of 17 patients, 8 female and 9 male were surgically treated for claw deformity. The dominant hand was affected in seven patients. The average age was 46 ± 15 (22-80) years, the average interval from onset of ulnar palsy to lassoplasty was 61 ± 91 (3-288) months. The final follow-up was performed after an average of 42 ± 32 (2-112) months. Claw deformity was resolved in 14 out of the 17 patients. The grip strength was on average 58 ± 28 % (11-96 %) of the unaffected hand, the mean disabilities of the arm, shoulder and hand (DASH) score was 32 ± 18 (5-68) points and the degree of patient satisfaction 7 ± 2 (0-10). According to own results and those in the literature lassoplasty can be recommended for the treatment of claw deformity.

Metacarpophalangeal Joint ,Ligaments ,Finger Injuries ,Humans - Abstract
Collateral ligament injuries of the metacarpal joints of the fingers are rare conditions. The injury should be diagnosed by clinical investigation and standard radiographs. Leading symptoms are local tenderness and joint instability. Instability is verified by clinical stress testing of the metacarpophalangeal joint in 90° of flexion. In Grade I injuries stability is preserved due to ligament attenuation or small partial tears. Grade II injuries show laxity with firm endpoint according to incomplete tear. In Grade III injuries instability without endpoint can be found as a result of complete tears. Radiographs may show avulsed bone fragments.In Grade I and II tears or non- displaced avulsion fragments treatment is conservative with buddy taping for 6 weeks. In case of persistent instability or grade III tears suturing or refixation of the ligament are performed. Small avulsion fragments are removed and the ligament is fixed to the bone. Greater avulsion fragments are fixed by suitable small implants. Adequate treatment will lead to reliable good results. Even in chronic tears reconstruction with local material or tendon transplants is usually successful.

The triangular fibrocartilage complex (TFCC) represents an important anatomical structure interposed between the ulnar carpus and the distal ulnar. Injuries and degenerative changes of the TFCC are of high clinical relevance and there are numerous treatment options available based on different concepts and which are being used to varying extents. The aim of this systematic review was to evaluate the effectiveness of different therapies for lesions of the TFCC. Studies on TFCC lesions were systematically reviewed, classified into evidence levels and selected according to predefined criteria. A total of 259 publications were identified as being potentially relevant and finally 35 studies could be included in the review. In addition, a survey was performed among German hand surgeons in order to identify commonly used procedures for TFCC lesions in Germany. The classification of Palmer is mostly used both in the literature and in Germany and therapeutic decisions are predominantly based on this classification. The systematic review revealed some common treatment strategies for traumatic and degenerative lesions. Generally, the level of evidence was poor for all identified publications. For this reason, evidence-based recommendations for the treatment of TFCC lesions could not be derived from the literature. There was broad consent between the results of the literature review and the survey.

Complex fragmentation of the distal radial articular surface often results in three major problems: some fragments are too small for stabilisation by standard plates or screws; in addition, substantial loss of articular surfaces and metaphyseal/subchondral bony defects frequently occur.To solve these problems the following strategy was developed: the fixation of small articular fragments was performed by small K-wires that were placed subchondrally and countersunk in the bone. In case of lost articular surfaces a silicone foil was inserted intra-articularly to induce a cartilage-like tissue. Bony defects were replaced by iliac crest bone grafts. Additional stability was achieved by dorsal and volar plate fixation or bridge plating.An average of 53° of extension, 44° of flexion, 74° of pronation, and 66° of supination were achieved. The grip strength was an average of 61% of that in the contralateral limb. The average radiographic measurements were -5° of palmar inclination, 21° of ulnar inclination, and 0 mm of positive ulnar variance. A good or excellent functional result was achieved for five of seven wrists according to the rating system of Gartland and Werley. According to the modified Mayo Wrist Score four of five wrists achieved a good and one a fair result.The DASH Score averaged 19 (6-59) points.The applied treatment resulted in stable, mobile wrists with reasonable alignment and nearly even articular surfaces. The functional results were similar to those reported by other authors for less complex distal radius fractures. This strategy seems to be a rational approach to the reconstruction of severely comminuted intra-articular fractures of the distal radius.

Critically injured patients are a very heterogeneous group, medically and economically. Their treatment is a major challenge for both the medical care and the appropriate financial reimbursement. Systematic underfunding can have a significant impact on the quality of patient care. In 2009 the German Trauma Society and the DRG-Research Group of the University Hospital Muenster initialised a DRG evaluation project to analyse the validity of case allocation of critically injured patients within the German DRG system versions 2008 and 2011 with additional consideration of clinical data from the trauma registry of the German Trauma Society. Severe deficits within the G-DRG structure were identified and specific solutions were designed and realised.A retrospective analysis was undertaken of standardised G-DRG data (§ 21 KHEntgG) including case-related cost data from 3 362 critically injured patients in the periods 2007 and 2008 from 10 university hospitals and 7 large municipal hospitals. For 1 241 cases of the sample, complementary detailed information was available from the trauma registry of the German Trauma Society to monitor the case allocation of critically injured patients within the G-DRG system. Analyses of coding and grouping, performance of case allocation, and the homogeneity of costs in the G-DRG versions 2008 and 2011 were done.The following situations were found: (i) systematic underfunding of trauma patients in the G-DRG-Version 2008, especially trauma patients with acute paraplegia; (ii) participation in the official G-DRG development for 2011 with 13 proposals which were largely realised; (ii) the majority of cases with cost-covering in the G-DRG version 2011; (iv) significant improvements in the quality of statistical criteria; (v) overfunded trauma patients with high intensive care costs; (vi) underfunding for clinically relevant critically injured patients not identified in the G-DRG system.The quality of the G-DRG system is measured by the ability to obtain adequate case allocations for highly complex and heterogeneous cases. Specific modifications of the G-DRG structures could increase the appropriateness of case allocation of critically injured patients. Additional consideration of the ISS clinical data must be further evaluated. Data-based analysis is an essential prerequisite for a constructive development of the G-DRG system and a necessary tool for the active participation of medical societies in this process.

People who have become victims of violence have manifold problems. Besides medical diagnostics and therapy, it is necessary to recognise the situation in which these patients have become such victims, to document the consequences of this violence for use in court and to offer further assistance. Victims of violence often contact primarily a trauma ambulance. The optimisation of the medical treatment of the victims is a relevant traumatological topic, which so far has received only very scant attention. Therefore the aim of this study was to evaluate the necessity for an interdisciplinary combination of treatments for the targeted treatment of these victims.Using a standardised data card a retrospective data analysis of all out-patients and all in-patients of a trauma centre with regard to the existence of a violent context was carried out for the year 2004. All such cases were included and the data were evaluated descriptively according to age, gender, information about the act of violence, consequences thereof, type and scope of the diagnostic findings, as well as inducements for further measures. In this context we differentiated between "domestic violence" and "public violence".The data of 7132 patients were evaluated. Altogether 347 victims of violence were identified (among them 109 victims of "public violence", 59 victims of domestic violence, and 179 cases that could not be allocated clearly). This results in a quota of 4.9% of all patients treated. The average age of the victims was 30.6 years. It was striking that in many cases the anamnesis and documentation were rather fragmentary.A very high percentage of victims of violence could be found among the patients needing traumatological treatment. With regard to the fragmentary care there is an enormous need for medical training and interdisciplinary treatment of victims of violence.

Congenital venous malformations (VM) at the hand are rare. VM consist of dysplastic venous vessels without progressive cellular proliferation. The therapy for VM is considerably different from that for vascular tumours (e. g., haemangiomas). Treatment options for vascular malformations are antithrombotic medication, local compression, resection of the VM, and obliteration of the lumina by percutaneous sclerosation. Here, the percutaneous sclerosation for the treatment of VM with sodium tetradecyl sulfate has been illustrated and discussed on the basis of 2 case reports.

Carpometacarpal (CMC) fracture dislocations of the 2nd through 5th ray are rare injuries whose extent is regularly underestimated in the initial radiographic evaluation of the hand. Obtaining a computed tomography scan is imperative due to the radiographic underrepresentation of the full bone and joint injury. Restoration of bone and joint anatomy of the affected region is of paramount import to prevent joint deterioration and loss of hand durability and dexterity. Early surgical intervention can lead to good functional results. Different operative treatment strategies exist with a common approach being Kirschner wire, screw or plate fixation after closed or open fracture reduction and joint relocation.

Articular fractures of the dorsal part of the distal phalanx may result in a painful dysfunction and a bothersome deformity of the distal interphalangeal joint. For this injury multiple treatment procedures exist. We performed a survey among German hand surgeons and a review of the literature in order to present current concepts of treatment and to verify the feasibility of a randomized trial. There is a tendency to prefer conservative treatment options. The indication for operative treatment depends on size and displacement of the articular fragment as well as on subluxation of the joint. Operative techniques vary widely and the comparability of their results is restricted. Complications more often occur after operative treatment. The type of injury and the individual demands of the patient are the most relevant factors for the choice of treatment. From the results of the survey and the review of the literature, a randomized trial of conservative and operative treatment has to be considered as a challenge.

The TraumaNetzwerk(D) DGU was founded 3 years ago and since then the majority of trauma centers have been registered and organized into regional trauma network services (TNW). Within these networks assessment criteria for transferring patients to higher level hospitals are defined. The purpose of this study was to evaluate the incidence, causes, implications and quality of care for patients with major trauma who were transferred for definitive treatment before implementation of the TraumaNetzwerk(D) DGU in Germany.The data of 19,035 patients listed in the German Trauma Register of the German Society for Trauma Surgery (DGU, 2002-2007) were analyzed. Patients with an injury severity score (ISS)9 and a blood pressure documented on admission were included into the study. Data were allocated according to patients where therapy was performed completely in the primary hospital of admission (group I; n=16,033; 84.2%) and patients transferred after primary care from one hospital to another centre for definitive care (group II; n=3,002; 15.8%). Comparative parameters were the pattern and severity of injury, physiological state on admission and clinical outcome.Mean ISS and percentage of patients with an ISS ≥25 did not differ significantly between groups. Of the patients who were transferred to a higher level trauma centre (group II) 20.7% needed catecholamines on admission, 10.1% were in shock (blood pressure90 mmHg) and 2.5% of the patients underwent resuscitation in the emergency department. Patients of group II had a considerably longer hospital stay (31.2±35.5 days) than patients of group I (24.8±27.1 days). Furthermore, treatment costs were significantly higher for group II (I: EUR 23,870; II: EUR 26,054).A relevant percentage of patients transferred from one hospital to another were hemodynamically and clinically unstable. To what extent the quality of patient transfer and therefore major trauma care is improved by the implementation of regional trauma networks in Germany remains to be seen over the next years.

Systematic reviews are fundamental decision-making tools for the assessment of the effectiveness of healthcare interventions and for determining future research fields. In the field of hand surgery, so far, there exists only a limited number of systematic reviews. According to the diversity and multitude of hand surgical topics, relevant fields for systematic reviews were identified by means of an expert ranking.A catalogue of 24 topics was extracted from publications of representative hand surgical journals. These topics were categorized and integrated into a questionnaire which was presented to 30 experts in the field of hand surgery. Every single topic had to be rated by marks from 1 (very relevant) to 5 (not relevant). Further topics could have been indicated. Averaging of the marks allowed to define a ranking and a prioritisation of the topics.29 of 30 questionnaires were returned. The ranking showed scapholunate ligament injury, Kienboeck's disease and scaphoid nonunion to have the highest relevance, followed by 5 other topics dealing with wrist problems. The lowest relevance was attributed to neck fractures of the fifth metacarpal, ulnar collateral ligament injury of the thumb metacarpophalangeal joint and postoperative management following replantation.The results of the presented survey allow for a prioritisation of topics for systematic reviews in hand surgery. The ranking of the topics emphasises the particular relevance of injuries and diseases of the wrist.

In addition to a stabile osteosynthesis autologous cancellous bone graft remains an essential therapy option in persistent non-union. Despite this therapy regimen persistent non-union can occasionally occur. The aim of this study was to evaluate the treatment of persistent non-union with a combination of platelet-rich plasma (PRP) and autologous cancellous bone.In this prospective study 17 patients with persistent non-union of long bones were treated by a combination of PRP and autologous iliac crest bone. Inclusion criteria were a minimum of one previously failed cancellous bone transplantation and an atrophic non-union persisting for 6-14 months (mean 9 months). The patients were examined clinically and radiologically at intervals of 3, 6 and 9 months postoperatively.After an average time of 17 months (range 15-23 months) the patients were treated by a combination of PRP and autologous cancellous bone. In all cases the non-union was successfully treated and osseous bridging was found radiologically after an average of 5 months (range 4-7 months) without any complications.The combination of PRP and autologous cancellous bone appears to be a safe and effective method for treatment of persistent non-union. The use of PRP does not result in substantial additional costs. Allergies and graft versus host reactions are not expected because of the autologous origin.

The primary goal in the treatment of carpal fractures is the preservation of a painless wrist function. Scaphoid fractures are the most common carpal fractures and when such a fracture is clinically suspected CT or MRI scans are usually advisable. Only stable and non-displaced scaphoid fractures can be treated conservatively, all other fractures require internal fixation with restoration of normal anatomy. Second most common are fractures of the triquetrum which can occur as chip avulsions of the dorsal rim and are usually treated symptomatically. Fractures of the body of the triquetrum should be treated according to the degree of instability and displacement. This is virtually true for all carpal bones. Perilunate fracture dislocations of the carpus deserve special attention. In these severe injuries a fracture line can run through all carpal bones but the scaphoid is mostly affected. Accurate reduction and internal fixation by screws and K-wires are indicated not only in these cases, but also in carpometacarpal fracture dislocations.

With a prevalence from 11.8 to 18% no fracture is as often associated with nerve damage as the humeral shaft fracture. Whether the radial nerve should be surgically explored in association with a palsy in humeral shaft fractures in order to exclude an interposition or discontinuity is being discussed controversially. The aim of this study was to assess the strategies for primary care of radial nerve palsies associated with humeral shaft fractures in Germany.In a standardised survey 495 traumatological and 134 neurosurgical clinics were interviewed regarding the treatment of primary radial nerve palsies after humeral shaft fractures. The distribution of the survey included all level-one trauma centres. Statistics were based on the supply strategies, the number of observed contusions, discontinuities and inter-position of the N. radialis in the fracture gap. Moreover, the results were recorded after primary neurorrhaphy.The evaluable response rate to the questionnaire was 56% (university hospitals 77%, level-one trauma centres 63%, level-two trauma centres 70%, level-three trauma centres 44%). 6097 humeral shaft fractures have been treated per year, the incidence of primary radial nerve palsy was 8.6%. Regarding the management strategies, 59% of the hospitals advocated exploration of the nerve, while 25% reported that the decision depends on the individual case. 16% reject the exploration in case of a primary nerve palsy. In the case of an exploration, contusions (74%) of the nerve were largely seen, followed by nerve interpositions in the fracture gap (19%) and discontinuity (7%). In the case of neurorrhaphy, a partial or complete remission was found in 87% of cases.Although a primary expectant procedure is recommended in the literature due to the high spontaneous remission rate of 90%, an early exploration of the nerve is often preferred in clinical practice. In these cases, the use of an interlocking intramedullary nail as a minimally invasive treatment option does not appear useful due to the direct exposure of the fracture zone and the radial nerve. Interestingly, the feared discontinuity occurs rarely. The impact of nerve interposition in the fracture gap without surgical exploration remains unclear due to the lack of visibility.There is no consensus concerning the treatment of radial nerve palsies after humeral shaft fractures in Germany. Discontinuities are rare, the rate of spontaneous recoveries is high. Whether and when an exploration of the radial nerve is obligatory in primary radial palsy remains unclear and should be clarified by prospective randomised trials.

A degenerative tear of the anterior tibial tendon is a rare event compared to other tendons. The purpose of this study was to evaluate the functional results after surgical refixation.In a retrospective study, we report the functional outcome of five consecutive operatively treated patients suffering from a tear close to the insertion site of the anterior tibial tendon. All patients were assessed postoperatively, the AOFAS and Richter scores were obtained and the range of motion in the ankle joint was evaluated.Preoperatively all patients presented with a significant walking impairment due to a reduced active dorsiflexion, so the decision for surgical refixation was made. In all cases an MRI scan was performed preoperatively. Postoperative immobilisation without weight-bearing was done for six weeks. All patients returned to their former activity level, were satisfied with the postoperative result and had a normal gait in the follow-up examination. The range of motion was equal on both sides, the median AOFAS score was 86 and the median Richter score was 90 out of 100. There were no postoperative complications.Untreated tears of the anterior tibial tendon lead to significant impairment of the ankle joint and deformities of the foot. There is no consensus about the treatment with recommendations for operative and non-operative treatment. Various surgical procedures have been described. The surgical reconstruction of the tendon leads to a restored function of the ankle joint and allows a normal gait and is therefore desirable. Due to the loss of function and the good results after surgical treatment in our study, the non-operative treatment is not advisable.Surgical repair of degenerative tears of the anterior tibial tendon leads to very good functional results and high patient satisfaction.

Fractures of the patella account for approximately 0.5% to 1.5% of all skeletal injuries. The diagnosis is made by means of the mechanism of injury, physical and radiological findings. The kind of treatment of patella fractures depends on the type of fracture, the size of the fragments, the integrity of the extensor mechanism and the congruity of the articular surface. Independent of the kind of treatment an early rehabilitation is recommended. Modified tension band wiring is the most commonly used surgical treatment for patella fractures and can be used for almost every type of fracture. Due the superior stability in biomechanical studies two parallel cannulated lag screws combined with a tension band wiring are the treatment of choice for horizontally displaced two-part fractures. In comminuted fractures a partial or total patellectomy may be necessary. However, since the loss of quadriceps muscle power and the poor outcome total patellectomy should be considered as a salvage procedure.

Life-threatening situations after multiple trauma which require interruption of the diagnostic algorithm and immediate surgical treatment after admission are a challenge for the multidisciplinary trauma team. The purpose of this study was to evaluate the incidence, causes, implications and relevance of life-threatening situations for major trauma patients after admission to trauma centers.Data of 12,971 patients listed in the German Trauma Register of the German Society for Trauma Surgery (DGU, 2002-2007) were analyzed. Patients with an injury severity score (ISS)16, no isolated head injury and primary admission to a trauma center were included. Data were allocated according to patients where the diagnostic algorithm in the resuscitation room was interrupted to perform emergency surgery (group Notop, n = 713, 5.5%) and patients who received early surgical care after completed diagnostics (group Frühop, n = 5,515, 42.5%). Comparative parameters were the pattern and severity of injury, physiological state and clinical outcome.Patients receiving emergency surgery showed an average ISS score of 39 ± 15 points, whereas patients receiving early surgery showed an average ISS of 31 ± 12 points. On admission patients in the emergency surgery group (44%) suffered from hemodynamic shock considerably more often than patients in the early surgery care group (15%, p0.001). This was indicated by the significant differences in systolic blood pressure on admission, amount of preclinical substituted volume, base excess on admission and substituted erythrocyte concentrates in early clinical course. Mortality was 46% in the emergency surgery group and 13% in the early surgical care group (p0.001). Severe injuries (AIS ≥ 4) of the thorax, abdomen and extremities (including the pelvis) were encountered considerably more often in the emergency surgery group. There was no statistical difference in occurrence of severe head injuries between the groups. Emergency surgery consisted of 50.5% laparatomy, 19.8% craniotomy, 10.0% thoracotomy and 9.3% pelvic surgery.Life-threatening situations after major trauma which require immediate surgical intervention in the resuscitation room rarely occur in Germany. Nevertheless, they are associated with a high mortality and prolonged and complex clinical course if primarily survived. Indications and decision-making processes of these challenging situations have to be practiced with standardized algorithms and should be considered for the future education of orthopedic surgeons in Germany.

Scaphoid fractures represent the most common carpal bone fractures. These fractures may be overlooked due to insufficient diagnostics and lead to non-union and disability. A standardized diagnostic procedure with X-ray examinations, CT scans and/or MRI is recommended. We report on a case where a scaphoid fracture was overlooked, probably because of an incorrect technique of the computed tomography.A 42-year-old man was admitted to our emergency room after a fall on the out-stretched wrist. X-rays showed no evidence of a bony lesion. In the follow-up examination on the next day, a scaphoid fracture was still suspected clinically. Because of that a CT scan in thin slice technique with axial layers and multiplanar reconstruction was performed but showed no sign of a fracture. Six weeks after the trauma the patient presented with persistent wrist pain. X-rays and a CT scan of the wrist now demonstrated an old waist fracture of the scaphoid. -Operative treatment with iliac crest bone grafting and screw fixation was performed.Early diagnosis and a correct description of the fracture pattern are of high value in the treatment of scaphoid fractures. X-rays combined with a CT scan or an MRI scan of the affected wrist are considered as the diagnostic standard. The reported case demonstrates that even with a thin thickness layer CT scan in axial planes, a scaphoid fracture can be overlooked. Therefore we recommend after primarily inconspicuous X-rays a CT scan with primary -oblique-sagittal layers in the longitudinal axis of the scaphoid. If this shows no fracture and the clinical suspicion persists, an MRI scan should be performed.

Due to advances in the development of the unidirectional locking plates there is now an increased use of multidirectional palmar locking plates in the treatment of distal radius factures. The purpose of this study was to evaluate a possible improvement of the treatment and results.This prospective cohort study investigated 40 patients with C1 and C2 Colles' fractures who had been treated with unidirectional and multidirectional locking plates. The average time for the follow-up examinations was 12.3 months (range 12-15 months) after surgery. The intra-operative functional (neutral-zero method), radiological and subjective (DASH score, VAS) results were evaluated.The intra-operative fluoroscopy time of the unidirectional group was 58 s shorter compared to the multidirectional group. All fractures healed without any complication. The radiological, subjective (DASH score) and objective results for both groups were good and showed no differences.Unidirectional palmar locking plates are equally suited for the therapy of C1 and C2 fractures as multidirectional palmar locking plates but multidirectional plates require a longer fluoroscopy time.

The objective of our study is to evaluate the functional and subjective results following subtalar dislocations without any associated bone injuries and to examine whether the direction of dislocation has any effect on the post-traumatic results.Over the period from February 1998 to May 2006, 56 patients with a subtalar dislocation were enrolled in the study. A subtalar dislocation without any associated bone injuries was only present in 13 patients. Follow-up examination after an average of 39.8 months was performed using the AOFAS Ankle-Hindfoot scale. The adapted classification developed by Altman was used to assess the post-traumatic degree of arthrosis radiologically.The average AOFAS score was 81, with good results in 11 patients and satisfactory results in 2 patients. The range of motion (ROM) for the ankle-hindfoot joint was 39.2 degrees .Despite the severity of the injury, the functional and subjective results of subtalar dislocations without any bone injuries are good. Generally, no early post-traumatic arthrosis occurs if there are no associated bone injuries. No differences were established between medial and lateral subtalar dislocations.

The aim of this study was to evaluate, whether early and radical debridement for hand infections within a single operation followed by at most one second-look revision, is considered as sufficient to heal the infection or not. As one revision followed by at most one second-look revision is not successful for all cases, the value of defined variables on the clinical course and their clinical relevance were evaluated.In this prospective study 50 patients (Mean age: 44; SD: 18 years of age) were included, who underwent surgical treatment in our hospital for severe infection of the hand. The individual course of each patient was documented. Patients, who needed more than two operations to heal the infection (group B) were compared with patients, who underwent one operation followed by at most one second-look revision (group A) under consideration of cause of infection, microbiology, pretreatment, preexistent diseases, and C-reactive protein.Mean inpatient treatment lasted 19.3 (SD: 19.2) days. Patients underwent 4.4 operations (range: 1-24). For infect healing 22 of the 50 patients (group A) required 1-2 surgical revisions. For 28 patients (group B) more than 2 revisions were necessary. For patients of group B the cause for the infection was more often unknown (p0.05). Patients who already underwent pretreatment externally showed a significantly increased risk for a prolonged course (p0.05). A preexistent disease or an increase of CRP had no significant influence on the healing process (p0.05).Even if the concept of early and radical surgical debridement is consistently and adequately realized, healing of hand infection was achieved in less than 50% of the cases with one revision followed by at most one second-look revision. Particularly patients, who already underwent pretreatment externally before evaluation of a hand surgeon seem to be inclined to a prolonged courses of treatment.

The combination of kyphoplasty and fixateur interne is an essential therapy with osteoporotic unstable fractures. Material costs of 5500 Euro are not sufficiently covered by returns through DRG I09. Thus operations are often performed in 2 stages, an initial one and a second 30 days later. This means more strain for the patient and partly also loss of correction. Therefore in 2008 we requested the InEK that codes for one-and two-segmental implantation of material in a vertebrae with preceding restoration of vertebral height (5-839.a0 and 5-839.a1) combined with a percutaneous dorsal operation with a screw-rod system in the future would be represented by I19B in G-DRG system with returns of 11,110,40 Euro. Prerequirement is coding of kyphoplastiy as main procedure and percutaneous implantation of a fixateur with procedure 5-835.5. Some procedures in orthopedic surgery implying technical improvements and rising implant costs are not sufficiently rewarded. Thus is make sense to inform InEK by corresponding proposals.

There are no reports in the literature about femoral fractures in adults with congenital femoral deficiency. We report on a femoral fracture in a 60-year-old patient with congenital femoral deficiency. Despite early difficulties in mobilisation and delayed union after an angle-stable plate osteosynthesis, full weight bearing was reached after 8 months. The treatment of fractures in combination with congenital femoral deficiency remains difficult and depends on the extent of the defect, the complexity of the fracture, and associated anomalies. The objective of the often demanding operative treatment of a femoral fracture in combination with a congenital femoral deficiency should be reestablishment of the patient's walking ability.

The femur is the largest, longest and strongest bone in the human skeleton. Fractures of the shaft of the femur can result from high energy as well as low energy trauma and 30% of patients have multiple injuries. In the clinical diagnostic special attention must be paid to the peripheral neurovascular status as well as the possibility of a compartment syndrome. Fractures of the femur shaft are defined according to the AO classification. Treatment is as a rule operative, except for children up the end of 4 years old. Medullary nailing is nowadays the method of choice and the nails can be implanted in an anterograde or retrograde direction. The introduction of nails after boring out the medullar is associated with an increased healing rate in comparison to non-boring techniques. Various techniques are available for the often promising method of repositioning and the intraoperative controls. Plating is reserved only for special situations. External fixation is of great value in adults for temporary fixation of fractures of the femur shaft. Full weight bearing is possible immediately following the operation depending on the type of fracture and method of treatment. Uncomplicated fracture healing does not result in a reduction in the ability to work. Despite the generally good prognosis and improvement in design and technology of implants, fractures of the femur shaft still represent a special challenge for the treating casualty surgeon.

The major goal in the treatment of metacarpal fractures is to restore the normal function of the hand. Radiological criteria and the clinical extent of displacement should be individually considered when taking the decision for or against conservative treatment. Internal fixation techniques must protect soft tissue structures. Small screws and plates have proven effective for head and shaft fractures, whereas intramedullary splinting is favoured for neck fractures. In instable and displaced fractures of the base of the first metacarpal, surgery is regularly performed to restore the bony shape and articular surface. To prevent functional impairments, early mobilization is desirable both during conservative treatment and following internal fixation.

The German DRG-System was advanced into version 2009. For orthopedic and trauma surgery significant changes concerning coding of diagnoses, medical procedures and concerning the DRG-structure were made.Analysis of relevant diagnoses, medical procedures and G-DRGs in the versions 2008 and 2009 based on the publications of the German DRG-institute (InEK) and the German Institute of Medical Documentation and Information (DIMDI).Changes for 2009 focussed on the development of DRG-structure, DRG-validation and codes for medical procedures to be used for very complex cases. The outcome of these changes for German hospitals may vary depending in the range of activities.G-DRG-System gained complexity again. High demands are made on correct and complete coding of complex orthopedic and trauma surgery cases. Quality of case-allocation within the G-DRG-System was improved. Nevertheless, further adjustments of the G-DRG-System especially for cases with severe injuries are necessary.
