[Conventional X-Rays of Ankle Joint Fractures in Older Patients are Not Always Predictive]. / Einschränkungen der Aussagekraft des konventionellen Röntgenbilds bei Sprunggelenksfrakturen im Alter.

Background: Ankle fractures are extremely common in the elderly, with an incidence of up to 39 fractures per 100,000 persons per year. We found a discrepancy between intraoperative findings and preoperative X-ray findings. It was suggested that many relevant lesions of the ankle joint in the elderly cannot be detected with plain X-rays. Methods: Complete data sets and preoperative X-rays of 84 patients aged above 60 years with ankle fractures were analysed retrospectively. There were 59 women and 25 men, with a mean age of 69.9 years. Operation reports and preoperative X-rays were analysed with respect to four relevant lesions: multifragmentary fracture pattern of the lateral malleolus, involvement of the medial malleolus, posterior malleolar fractures and bony avulsion of anterior syndesmosis. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy and prevalence were calculated. Results: The prevalence of specific ankle lesions in the analyzed cohort was 24 % for the multifragmentary fracture pattern of the lateral malleolus, 38 % for fractures of the medial malleolus, 25 % for posterior malleolar fractures and 22.6 % for bony avulsions of the anterior syndesmosis. Multifragmentary fracture patterns of the lateral malleolus (sensitivity 0 %) and bony avulsions of the anterior syndesmosis (sensitivity 5 %) could not be detected in plain X-rays of the ankle joint at all. Fractures of the medial malleolus and involvement of the dorsal tibial facet were detected with a sensitivity of 96.8 % and 76.2 %, respectively, and specificity of 100 % in both cases. Conclusions: This study confirms that complex fracture patterns, such as multifragmentary involvement of the lateral malleolus, additional fracture of the medial malleolus, involvement of the dorsal tibial facet or bony avulsion of the anterior syndesmosis are common in ankle fractures of the elderly. Therefore, CT scans should be routinely considered for primary diagnosis, in addition to plain X-rays.

[Type 2 dens fracture in the elderly and therapy-linked mortality : Conservative or operative treatment]. / Typ-II-Densfrakturen des alten Menschen und therapiebedingte Mortalität : Konservative oder operative Behandlung.

BACKGROUND: Type II fractures of the odontoid process of the axis are the most common injury of the cervical spine in elderly patients. Only little evidence exists on whether elderly patients should be treated conservatively or surgically. MATERIAL AND METHODS: The mortality and survival probability of 51 patients were determined in a retrospective study. The range of motion, pain and the neck disability index were clinically investigated. RESULTS: Of the 51 patients 37 were treated surgically and 14 conservatively. The conservatively treated group showed a higher mortality (64 % vs. 32 %). Kaplan-Meier analysis revealed a median survival of the conservatively treated group of 29 months, whereby during the first 3 months of treatment this group showed a higher survival probability and afterwards the surgically treated group showed a higher survival probability. The clinical examination of 20 patients revealed limited range of motion of the cervical spine. Additionally, moderate levels of pain and complaints were recorded using the neck disability index. CONCLUSION: Fractures of the odontoid process pose a far-reaching danger for elderly patients. A balanced assessment of the general condition should be carried out at the beginning of treatment of these patients. In the early phase following trauma no differences were found with respect to survival rates but for long-term survival the operatively treated group showed advantages; however, these advantages cannot be causally attributed to the choice of therapy.

[3D-Navigated Implantation of Pedicle Screws in the Cervical Spine - Experience and Analysis of Complications]. / 3-D-navigierte Pedikelschrauben der Halswirbelsäule ­ Erfahrungen und Komplikationsanalyse.

Background: Placing transpedicular screws in the cervical spine is a special challenge for spine surgeons, due to the anatomical features of this part of the spine. During the last 15 years, computer-aided navigation systems have been developed to facilitate this procedure and to make it safer for patients. One option is navigation by intraoperatively acquired data sets with the use of an 3D C-arm. Patients/Material and methods: Our retrospective study evaluates transpedicular screws in the cervical spine placed by 3D C-arm navigation, within a 6 year period in a level 1 trauma centre. We recorded epidemiological data, operation time and especially general adverse events, as well as revision surgery, including reasons for revision. We used a C-arm Arcardis Orbic 3D (Siemens, Munich), connected to a navigation system (VectorVision, Brainlab, Munich). Results: Between July 2007 and July 2013, 207 transpedicular screws were placed in 58 patients. The main indications were trauma (69 %), rheumatic diseases (20.7 %) and tumour (8.6 %). The most commonly instrumented cervical spine segments were C2 (53.5 %)%), C7 (10.3 %) and C5 (8.6 %). In nearly 95 % of the cases, we performed an intraoperative 3D scan after screw or k-wire placement to control the screw position. We found unacceptable malposition in 7.2 % of patients. This was corrected at once. Ten patients had to be revised: seven times due to wound problems, twice because of implant failure and once for treatment of CSF leakage. Three screws (1.5 %) led to injuries of the vertebral artery, once with a lethal outcome. Analysis of these cases showed that the 3D scan gave reduced data quality, due to reduced bone density or anatomical factors. Conclusion: Intraoperative 3D C-arm navigation seems to be a reliable option for transpedicular screw placement in the cervical spine. Complication rates were comparable to published values. 7.2 % of all screws were corrected intraoperatively after a control scan. Therefore possible revisions could be avoided during primary surgery. Analysis of problematic cases led to a change in our treatment strategy: in patients with poor bone quality and/or anatomical problems which lead to 3D scans of poor quality, we avoid transpedicular screw placement in C6 or higher, in order to prevent injuries of the vertebral artery.

[Quality of life and job performance resulting from operatively treated tibial plateau fractures]. / Lebensqualität und Arbeitsfähigkeit nach operativer Behandlung von Tibiakopffrakturen.

BACKGROUND: The aim of this article is to present the functional results and the effect on quality of life of surgically treated tibial plateau fractures in physically active and working patients with multiple and serious injuries. In addition, the relationships between functional and radiological outcome were evaluated and compared with activity in daily and professional life. PATIENTS AND METHODS: In all, 41 injured patients were followed up a mean of 47 months after surgical treatment and examined with radiological, functional, as well as quality of life score. RESULTS: In the radiological scoring, a mean value of 72 points (max 100 points) was achieved. In the activity score, there was an average of 63.5 points (max 100 points). When evaluating the health-related quality of life, an average score of 69.6 points was achieved. There was a significant relationship between radiological and activity scores and the radiological and life quality scores. Furthermore, the relationship between activity and quality of life scores was considered significant. Surgeon's influence on the functional outcome could be confirmed. CONCLUSION: The functional and the radiological results were moderate. Quality of life was permanently affected by the consequences of tibial plateau fracture in 12 patients; 11 patients were not re-employed. However, the quality of life was assessed as good or very good and 28 patients had returned to work. The quality of life was firmly linked to the radiological and functional parameters, which tended to be influenced by the quality of the primary surgical treatment when looking at the overall population.

[Shortening deformities of the clavicle after diaphyseal clavicular fractures : Influence on patient-oriented assessment of shoulder function]. / Verkürzungsfehlstellung des Schlüsselbeins nach diaphysären Klavikulafrakturen : Einfluss auf die patientenorientierte Bewertung der Schulterfunktion.

OBJECTIVE: The aim of this study was the evaluation of patient-oriented outcome scores for shoulder function and residual complaints after diaphyseal clavicular fractures with respect to shortening deformities. MATERIAL AND METHODS: The analysis was based on data of 172 adult patients (mean age 39 ± 14 years) with healed clavicular fractures treated operatively (n = 104) or conservatively (n = 67). The control population consisted of 35 healthy adults without shoulder problems and 25 patients with nonunion after conservative treatment. The subjective estimation of the level of pain was collated on a visual analog scale (VAS 1-100 points), together with the relative Constant and Murley score, the Cologne clavicle score, the disabilities of the arm, shoulder and hand (DASH) score and a bilateral comparison of the length difference of the clavicles. RESULTS: Patients with a clavicular length difference of > 2 cm had significantly (p < 0.001) more pain, a greater loss of mobility and significantly lower values in the scoring system of Constant and Murley, the DASH and Cologne clavicle scores compared to patients with clavicular length differences < 0.5 cm and healthy controls (p < 0.001). CONCLUSION: The results of this study showed that shortening deformities after clavicular fractures in adults have a large impact on the functional result and patient-oriented outcome scores. The aim of the therapy of diaphyseal clavicular fractures should therefore concentrate on reconstruction of the anatomical length of the clavicle.

Compartments of the foot: topographic anatomy.

Recent publications have renewed the debate regarding the number of foot compartments. There is also no consensus regarding allocation of individual muscles and communication between compartments. The current study examines the anatomic topography of the foot compartments anew using 32 injections of epoxy-resin and subsequent sheet plastination in 12 cadaveric foot specimens. Six compartments were identified: dorsal, medial, lateral, superficial central, deep forefoot, and deep hindfoot compartments. Communication was evident between the deep hindfoot compartment and the superficial central and deep central forefoot compartments. In the hindfoot, the neurovascular bundles were located in separate tissue sheaths between the central hindfoot compartment and the medial compartment. In the forefoot, the medial and lateral bundles entered the deep central forefoot compartment. The deep central hindfoot compartment housed the quadratus plantae muscle, and after calcaneus fracture could develop an isolated compartment syndrome.

[A simple clavicle score. An effective and reliable classification for outcome assessments of midclavicular fractures]. / Ein einfacher Klavikulascore. Bewertungssystem zur Beurteilung der Behandlungsergebnisse nach Frakturen des mittleren Klavikuladrittels bei Erwachsenen.

BACKGROUND: To compile an evaluation system (score) for post-treatment outcomes of midclavicular fractures, 172 patients were studied on average 15 months post-injury. As a control group 45 healthy volunteers were examined. The most relevant elements were filtered out for use in a new classification system, the Clavicle Score (CS). METHODS: The CS is based on a system of three partnered objective/subjective items as well as radiographic assessment of fracture healing. For the partnered items, subjective responses with the most significant correlation to the specific objective parameters were selected. Total score cutoff values (very good, good, moderate, poor) were established to keep interpretation simple. To validate the system, linear regression analysis was performed comparing the CS to two established assessment systems (Constant Score and the DASH Score). ERGEBNISSE: The correlation coefficients R=0.756 (Constant) and R=0.687 indicated that the conclusions were comparable and therefore valid. The reliability coefficient Cronbach's alpha was calculated at 0.8241, indicating high reliability. CONCLUSION: The CS is a simple, valid and reliable instrument to assess outcomes post-midclavicular fracture.

[Appearance of complex regional pain syndrome after intramedullary nailing of a clavicle fracture]. / Auftreten eines Complex-regional-pain-Syndroms nach intramedullärer Nagelung einer Klavikulaschaftfraktur.

After operative correction of a clavicle fracture using an elastic stable intramedullary nail the patient presented signs of delayed fracture healing after 2 months. During the sixth postoperative month the 28-year-old obviously pain-ridden female patient showed dystonia of the shoulder girdle and allodynia surrounding the operation field. Upon these findings, we decided - as a result of the complex regional pain syndrome that had not been previously described in this location - to treat the patient by administering bisphosphonates, multimodal analgetic therapy, physiotherapy and occupational therapy. Fourteen months after surgery, the patient showed no remaining symptoms, and the fracture had consolidated at that time.

[Non-union of the clavicle after intramedullary nailing with a steel Kirschner wire]. / Pseudarthrose nach intramedullärer Nagelung der Klavikula mit einem Stahl-Kirschner-Draht.

Elastically stable intramedullary nailing is a safe surgical procedure used to treat mid-shaft clavicular fractures of types A and B according to the Orthopaedic Trauma Association (OTA) classification. In the case reported intramedullary fixation with a Kirschner wire and an incorrectly performed surgical technique led to pseudoarthrosis (non-union). After revision surgery with an elastically stable titanium nail and a correct surgical technique, fracture healing was achieved.

[Percutaneous plate osteosynthesis for clavicular fractures. Initial description]. / Die perkutane Plattenosteosynthese der Klavikula. Eine Erstbeschreibung.

Insertion of titanium nails for type A and B clavicular fractures can fail intraoperatively due to the small diameter or irregular nature of the medullary canal. At present, such failures lead to open reduction and fixation (ORIF) with plates. In type C fractures (comminuted fractures), a telescoping effect is observed so that ORIF is the only suitable alternative besides nonoperative therapy. A suitable minimally invasive solution for type C fractures and as a salvage procedure for failed intramedullary nailing of type A and B fractures is presented here for the first time with a percutaneous application of an LC plate to the clavicle.

[Comparison of the nipple projection after reconstruction with three different methods]. / Langzeitergebnisse nach Mamillenrekonstruktion mit verschiedenen Verfahren.

The creation of the nipple-areola complex represents the final stage in the surgical treatment of breast cancer patients. Preservation of the nipple projection is important and difficult to achieve. A huge number of different methods for nipple reconstruction have been well described, but some of them fail secondary to scar contraction with loss of projection. Furthermore, there are only few studies investigating the degree of shrinkage over time in nipple projection. Aim of this study was to determine the long-term projection of the reconstructed nipple. We compared three different methods that have been used in our department for nipple-reconstruction. Between May 1994 and December 2001, reconstruction of the breast mound was performed in 146 patients. 86 patients who underwent a unilateral reconstruction of the nipple have been examined. The nipple reconstructions were performed by using either a modified skate-flap (n = 29), a quadrapod-flap (n = 37) or by nipple sharing (n = 20). Nipple projection was measured at least six months after the reconstruction. Patients were followed an average of 10.9 +/- 3.62 months. 38 patients had tissue expansion and implantation for breast mound reconstruction. 29 patients had autologous breast mound reconstruction and 19 patients were treated by a combination of both. The mean projection was 3.45 mm (+/- 1.23) in the nipple sharing group, 6.03 mm (+/- 1.86) in the quadrapod-flap group and 9,24 mm (+/- 2.45) in the skate-flap group. The mean decrease in projection for the nipple sharing was 27.6 +/- 18.2 % while the skate flap lost 45.0 +/- 11.1 % and the quadrapod flap 49.9 +/- 11.56 %. Comparison between the three groups using a Student-t test showed a statistical significance between the nipple sharing and the two other groups (p < 0.001), while there was no significance between the local flap groups (p = 0.082). The best long-term nipple projection was obtained by the nipple sharing, but the indication therefore is rare whereas local flaps are used more often. We conclude that although both methods are effective, the skate flap allows the surgeon to overbuild the nipple and achieve a higher projection. In addition, the results also indicated that nipple projection on the breast mound reconstructed with autologous tissue achieved a better long-term outcome.

[Reconstruction of shoulder-girdle symmetry after midclavicular fractures. Stable, elastic intramedullary pinning versus rucksack bandage]. / Wiederherstellung der Symmetrie des Schultergürtels bei Klavikulafrakturen Elastisch stabile intramedulläre Osteosynthese vs. Rucksackverband.

The aim of this study was to compare the results achieved in two groups of 20 patients treated for midclavicular fracture. The first group (mean age 36 years) was treated non-operatively with a rucksack bandage, whereas the second group (mean age 37 years) underwent intramedullary fixation with a titanium pin using a minimally invasive, unreamed technique. At follow-up, which averaged 3.1+/-0.9 years in group 1 and 2.9+/-0.7 years in group 2, the result of treatment, as indicated by the Constant score, functional outcome and cosmetic outcome, was significantly better in the group undergoing operative treatment. Clavicle shortening was significantly ( P=0.027) higher in patients treated with a rucksack bandage. The absolute Constant score averaged 78+/-23 in group 1 and 97+/-4 in group 2 ( P=0.001). The Constant rating scale showed a significant difference between patients with clavicle shortening of less than 1 cm and 1 cm shortening or more. There were two non-unions in group 1 but none in group 2. Refractures were not observed in either group. According to these results, intramedullary fixation with a titanium pin seems to be more advantageous in midclavicular fractures than non-operative treatment. As the operation is well received by the patients, it should be offered to them as an alternative treatment to the rucksack bandage.
