Proximal humeral fractures in children - controversies in decision making. Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02534-7. [PMID: 38689019 DOI: 10.1007/s00068-024-02534-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/20/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND Proximal humeral fractures in children are rare and usually treated non-operatively, especially in children younger than ten. The decision between operative and non-operative treatment is mostly based on age and fracture angulation. In the current literature, diverging recommendations regarding fracture angulation that is still tolerable for non-operative treatment can be found. Besides, there is no consensus on how fracture angulation should be determined. This study aimed to determine whether leading experts in pediatric trauma surgery in Germany showed agreement concerning the measurement of fracture angulation, deciding between operative and non-operative treatment, and choosing a treatment modality. METHODS Twenty radiographs showing a proximal humeral fracture and the patient's age were assessed twice by twenty-two senior members of the "Section of Pediatric Traumatology of the German Association for Trauma Surgery". Experts determined the fracture angulation and chose between several operative and non-operative treatment modalities. The mean of individual standard deviations was calculated to estimate the accuracy of single measurements for fracture angulation. Besides Intra-Class Correlation and Fleiss' Kappa coefficients were determined. RESULTS For fracture angulation, experts showed moderate (ICC = 0.60) interobserver and excellent (ICC = 0.90) intraobserver agreement. For the treatment decision, there was fair (Kappa = 0.38) interobserver and substantial (Kappa = 0.77) intraobserver agreement. Finally, experts preferred ESIN over K-wires for operative and a Gilchrist over a Cuff/Collar for non-operative treatment. CONCLUSIONS Firstly, there is a need for consensus among experts on how fracture angulation in PHFs in children should be reliably determined. Our data indicate that choosing one method everybody agrees to use could be more helpful than using the most sophisticated. However, the overall importance of fracture angulation should also be critically discussed. Finally, experts should agree on treatment algorithms that could translate into guidelines to standardize the care and perform reliable outcome studies. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION Clavicle shaft fractures are among the most common fractures in childhood and adolescence. In the past they were almost exclusively treated conservatively but in recent years there has been an increase in surgical treatment. Nevertheless, exact recommendations for the choice of diagnostics and for the treatment regimen do not yet exist. MATERIAL AND METHODS Therefore, our aim was to develop a consensus within the 7th scientific working meeting of the section for pediatric traumatology in the German Society for Trauma Surgery based on expert opinion. RESULTS Single-plane radiographic imaging is considered the gold standard diagnostic tool. Children younger than 10 years are primarily treated conservatively, and the type of immobilization is secondary. In girls older than 12 years and boys older than 14 years, fractures dislocated by more than the shaft width and shortened by > 2 cm should be treated by open reduction and stabilized by osteosynthesis, followed by free-functional follow-up treatment. CONCLUSION In addition to X‑rays, diagnostics using ultrasound must be further established. Treatment continues to be primarily conservative, but surgical treatment is also important, especially in adolescents. If the indications are correct, a good outcome can be expected regardless of the choice of treatment.

Management of juvenile and aneurysmal bone cysts: a systematic literature review with meta-analysis. Eur J Trauma Emerg Surg 2023; 49:361-372. [PMID: 35989377 PMCID: PMC9925490 DOI: 10.1007/s00068-022-02077-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 08/08/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Numerous approaches to the management of juvenile and aneurysmal bone cysts (ABC) are described in the specialist literature together with discussion of the associated healing and recurrence rates. Since there is currently no evidence-based treatment standard for these conditions, the aim of this systematic literature review with meta-analysis was to examine the different management approaches, evaluate the corresponding clinical outcomes and, as appropriate, to formulate a valid treatment recommendation. METHODS A systematic search on OVID Medline® based on a pre-existing search strategy returned 1333 publications. Having defined inclusion and exclusion criteria and analysis of the relevant full texts, 167 publications were included in the descriptive analysis and 163 in the meta-analysis. For this purpose, different subgroups were created, based on the type of cyst and the therapeutic procedure. Those subgroups were then analysed in relation to their healing rates, the number of recurrences and complication rates. RESULTS For aneurysmal bone cysts, both surgical removal and Doxycycline injection lead to excellent outcomes (98% healing) and low recurrence rates (6% and 11% resp.). Curettage (91% healing), including its combination with autologous cancellous bone graft (96% healing), showed very good healing rates but higher recurrence rates (22% and 15%, resp.), which were however improved by preoperative selective arterial embolization. A critical view must be taken of radiotherapy (90% healing) and the injection of alcohol (92% healing) because of their high complication rates (0.43/cyst and 0.42/cyst, resp.). In the management of juvenile bone cysts, surgical interventions like curettage and cancellous bone graft (87% healing) are far superior to non-surgical approaches (51% healing), furthermore, the application of autologous cancellous bone graft reduced the recurrence rate (3% recurrence) compared to curettage alone (20% recurrence). In subgroup analysis, treatment by ESIN was found to produce excellent outcomes (100% healing), though the patient collectives were small. CONCLUSION Surgical procedures to treat aneurysmal bone cysts appear to be the method of choice whereby Doxycycline injection may be an alternative. A surgical approach should be preferred in the treatment of juvenile bone cysts.

Abstract
Osteosynthesis refers to various surgical procedures, closed or open, for the treatment of fractures of any age. To document and control the osteosynthesis and the healing process X‑ray controls of the affected skeletal segment are performed during the operation and at regular intervals. To assess the quality of an osteosynthesis or to identify a complication, a comprehensive and systematic image review is useful. This includes the assessment of the restoration of the functional anatomy, the position of the material in relation to the surrounding structures, an evaluation of the stability as far as this is possible, and a control of the bone healing in a functionally correct position.

Simple traumatic elbow dislocations; benefit from early functional rehabilitation: A systematic review with meta-analysis including PRISMA criteria. Medicine (Baltimore) 2021; 100:e27168. [PMID: 34871203 PMCID: PMC8568443 DOI: 10.1097/md.0000000000027168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 08/16/2021] [Indexed: 01/05/2023] Open
Abstract
INTRODUCTION Elbow dislocation is the second most frequent joint dislocation after shoulder dislocation. They have a high relevance because they can result in subsequent damage and limitations in range of motion. The treatment options are controversially discussed.The purpose of this systematic review and meta-analysis was to review the literature and analyze the evidence of early functional rehabilitation. METHODS A systematic literature search was performed via Ovid Medline, whereby 1645 publications were identified and evaluated in a stepwise approach. Of these publications 29 met the inclusion criteria of the authors and described simple elbow dislocations in 5765 patients.Data from the studies and subgroups included were initially categorized descriptively in conservative and surgical primary therapies, in immobilizing (immobilization lasting 2 weeks or longer) and free-functional follow-up treatments, and those data were then extracted from each subgroup in absolutes. We then pooled these numbers into descriptive statistics to ensure their comparability. We determined the success rates from the numbers of excellent and good results of the specific used outcome scores. RESULTS The effect estimate of the conservative therapy's success rate was 84% and for surgical treatment 80% (P < .0001). The difference between the immobilizing treatment (78% success rate) and early-function therapy (83% success rate) was significant (P = .002).In a subgroup analysis the success rate of conservative and immobilizing therapy was 79%, of conservative and early-functional therapy 91%, of surgical and immobilizing groups' was 77% and of the surgical and early-functional therapies was 93%. The difference among the 4 treatment options was significant (P < .0001), as were differences between the 2 conservative groups (P < .0001) and between the 2 surgical groups (P = .044). DISCUSSION Conservative therapy is the dominant therapy. Regardless of the primary therapy chosen in simple elbow dislocations: early functional follow-up care seems to be superior to immobilizing therapy with a duration more than 2 weeks.

Abstract
BACKGROUND Numerous predisposing factors are known for patellar dislocations but the extent to which these or the trauma cause the dislocation is often unclear. AIM This study investigated whether the analysis of the accident mechanism and anatomical predisposition in juvenile patellar dislocations enables a conclusion as to the causality. MATERIAL AND METHODS Retrospective cohort study, evidence level III. In-house employers' liability insurance association (BG) cases with the diagnosis of patella dislocation in patients under 18 years were descriptively evaluated with respect to demographic and predisposing aspects as well as regarding accident information. The accident mechanisms were sorted into subgroups: direct impact, trivial trauma, fall, torsional trauma. RESULTS A total of 54 patellar dislocations were identified with a patient age of 14 years (range 9-18 years). A mild valgus configuration was found in 39% of the cases, on average normal torsion, a tibial tuberosity-trochlea groove (TTTG) distance of 17 mm (range 8-24mm), with 41% a high proportion of patella alta and a trochlear deformity in 57%. Only 20% of the children had no relevant predispositions. The trivial traumas showed the highest proportion of recurrent dislocations with 50% and in the other accident categories the proportion of first dislocations was >75%. In the fall cohort the rate of children without relevant predisposition was highest. CONCLUSION The predisposition rate in infantile patellar dislocations is high; however, falls are always significant accident events as well as medial direct impact. Torsional trauma is also a significant causative factor, unless high-grade trochlear dysplasia is present, whereas trivial traumas are not.

Effectiveness and complications of primary C-clamp stabilization or external fixation for unstable pelvic fractures. Injury 2019; 50:1959-1965. [PMID: 31477239 DOI: 10.1016/j.injury.2019.08.039] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 08/21/2019] [Accepted: 08/25/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND AND PURPOSE Unstable pelvic fractures frequently require emergency stabilization using a C-clamp or external (CC/EF) fixation. However, the effectiveness of this intervention and associated complications are still a matter of debate. PATIENTS AND METHODS The analysis used data available from the German Pelvic Trauma Registry to study general complications, infections and mortality after primary stabilization using CC/EF in 5,499 patients (n = 957 with vs n = 4,542 without). Furthermore, the subgroups with secondary surgery (n = 713 vs n = 1,695), and ilio-sacral screw implantation following C-clamp stabilization were evaluated (n = 24 vs n = 219). Calculated odds ratios were adjusted for potential confounders. RESULTS Patients treated by CC/EF were younger (45 ± 20 vs 62 ± 24 years), had more C-type fractures (65% vs 28%), higher ISS (≥25 63% vs 20%) and displacement (≥3 mm 81% vs 41%), and more complex fractures (32% vs 5%). These features were independent risk factors for complications (p < 0.001). While mortality was reduced after CC/EF stabilization by 32% (OR 0.68 95%CI 0.49-0.95), the risk for general complications was slightly increased (OR 1.25 95% CI 1.02-1.53). In patients undergoing secondary surgery, CC/EF fixation had no influence on mortality, general complications or infections. Related to preceding C-clamp stabilization (OR 4.67 95% CI 1.06-20.64), the risk for infection increased from 3.2% to 20.8% in ilio-sacral screw fixation. INTERPRETATION Primary stabilization of unstable pelvic fractures with C-clamp or external fixation is associated with a decreased mortality and was not an independent risk factor for complications after secondary surgery. However, the risk for infection after ilio-sacral screw fixation increased almost 5-fold after C-clamp use.

Decision-making, therapy, and outcome in lateral compression fractures of the pelvis - analysis of a single center treatment. BMC Musculoskelet Disord 2019; 20:217. [PMID: 31092220 PMCID: PMC6521455 DOI: 10.1186/s12891-019-2583-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Accepted: 04/23/2019] [Indexed: 02/16/2023] Open
Abstract
Background Pelvic lateral compression fractures are the most stable of the unstable fractures. Therefore, decision making regarding operative or non-operative therapy is still a matter of debate. Methods Factors, influencing decision making for therapy, were explored based on prospectively collected register data of a single Level-1 trauma center. The analysis included epidemiological records such as age and gender, and injury characterizing parameters such as degree of displacement and the Injury Severity Score (ISS). In-hospital mortality and complications served as short-term outcome variables. After matching for relevant confounders, long-term results were compared between operatively and non-operatively treated patients, evaluating the Merle d’Aubigne and the EQ. 5D-3 L scores. Results Over an 11-year period (2004–14), 134 patients suffered from lateral compression fractures out of 567 pelvic fractures (33%). After excluding patients with clear indications for operation (complex pelvic fractures and pubic symphysis ruptures) and pediatric fractures, 114 patients could be included in the analysis. Sixty-one patients were treated conservatively (54%), 53 with an operation (46%). The operated patients were younger (43.7 vs 58.3 years), had higher ISS (19.9 vs 15.5 points) and fracture displacements (2.3 vs 4.9 mm) (p < 0.001 for all). The length of hospital stay was shorter in the conservatively treated group (12.7 vs 17.3 days, p < 0.02). Although the types of complications were different, the incidence was not. The mortality was less in the operated group (1.9% vs. 6.6%), however, a logistic regression analysis showed that only the ISS was an independent risk factor, but not the type of therapy. Merle d’Aubigne and EQ. 5D-3 L scores were not different in the matched cohorts. Conclusion Decision-making for operative therapy was favored in severely injured young patients with high displacement. However, short- and long-term outcomes showed no difference between operatively and non-operatively treated patients. Trial registration DRKS, no. 00000488.

Age- and severity-adjusted treatment of proximal humerus fractures in children and adolescents-A systematical review and meta-analysis. PLoS One 2017; 12:e0183157.

Abstract
BACKGROUND Fractures of the proximal humerus in patients under the age of 18 years show a low incidence; existing clinical studies only comprise small patient numbers. Different treatment methods are mentioned in the literature but a comparison of the outcome of these methods is rarely made. Up to now, no evidence-based algorithm for conservative and operative treatment is available. The aim of this systematic review with meta-analysis was therefore to gather the best evidence of different treatment methods and their associated functional outcome, complication rates, rates of limb length discrepancies and radiological outcome. METHODS AND FINDINGS The OVID database was systematically searched on September 30th in 2016 in order to find all published clinical studies on the subject of proximal humerus fractures of patients ≤18 years. Exclusion criteria were previously defined. The Coleman Methodology Score was used to evaluate the quality of the single studies. 886 studies have been identified by the search strategy. 19 studies with a total of 643 children (mean age: 11.8 years) were included into the meta-analysis with a mean Coleman Methodology Score of 71 ± 7.4 points. 18 of the 19 studies eligible for inclusion were retrospective ones, of the best quality available (mean follow-up ≥ 1 year, mean follow-up rate ≥ 65%). 56% of the patients were male. Proximal humerus fractures were treated conservatively in 41% and surgically in 59% of the cases (Elastic Stable Intramedullary Nailing (ESIN): 31%; K-wires: 20%; 8% other methods, e.g. plate osteosynthesis, olecranon traction). The overall success rate (good/excellent outcome) for all treatment methods was 93%. The success rate of ESIN (98%) and of K- wire fixation (95%) was significantly higher (p = 0.01) than the success rate of conservative treatment options (91%). A subgroup analysis of severely displaced fractures (Neer grade III/IV, angulation ≥ 20°) resulted in a change of success rates, to the disadvantage of conservative treatment methods (conservative treatment 82%, ESIN 98%, K-wires 95%; p < 0.001). Complication rates did not differ to a significant extent. 9% of the complications occurred in the patients treated by K-wire fixation, 8% if a conservative treatment option was chosen and 7% in the fractures that were stabilized by ESIN. A change from a one-nail technique to a two-nail technique reduced the complication rate of ESIN significantly. Follow-up X- rays without residual deformity could be found in 96% of the patients treated by ESIN, a rate which was higher than in the patients treated conservatively (93%) or by K-wire fixation (88%). The rate of arm length discrepancies at final follow- up was lower if the fractures were stabilized by ESIN (4%) than if they were treated conservatively (9%) or by K-wires (19%). An evaluation of age-dependent treatment options was performed. CONCLUSIONS By performing this meta-analysis an evidence-based treatment algorithm could be introduced to treat the fractures according to the severity of displacement and according to the patient's age. For severely displaced fractures ESIN is the method of choice, with the best clinical and radiological outcome.

Abstract
INTRODUCTION Many publications, mainly from other countries, suggest that the treatment of seriously injured children might be better in specialised paediatric trauma centres than in general trauma centres. Data from Germany are not available yet, but those from abroad were used for the recommendations made by the German Association for Trauma Surgery (DGU) on the topic of paediatric trauma in the "White Paper on Trauma Care". The goal of this study was to analyse whether the outcome of severely injured children is dependent on treatment level and on the availability of a paediatric surgeon based on the given data. MATERIALS AND METHODS Data from the "TraumaRegister DGU" between 2002 and 2012 were used. Children aged 1-15 years treated during the period 2002-2012 were included. Severity had to reach a minimum Injury Severity Score (ISS) of 9 and the treatment had to involve a stay at an Intensive Care Unit. Patients with an ISS ≥9 who died were also included to take into consideration children with particularly severe injuries. RESULTS Hospitals without a paediatric surgeon transferred the patients significantly more frequently (p < 0.001). Mean hospital stay was shorter in centres with a paediatric surgeon, with slightly longer median stays at an Intensive Care Unit. Hospitals without a paediatric surgeon performed slightly more frequent surgical interventions on injured children (barely significant at p = 0.045). The death rate and the calculated Revised Injury Severity Classification (RISC) II prognosis were the same with or without the presence of a paediatric surgeon. No difference was found in the Glasgow Outcome Score (GOS) between the group with and the group without involvement of a paediatric surgeon. DISCUSSION Overall, the medical care of seriously injured and polytraumatised children in Germany is good at all levels of treatment whether a paediatric surgeon is involved or not.

Spinal Orthoses: The Crucial Role of Comfort on Compliance of Wearing - Monocentric Prospective Pilot Study of Randomized Cross-Over Design. ACTA CHIRURGIAE ORTHOPAEDICAE ET TRAUMATOLOGIAE CECHOSLOVACA 2017; 84:91-96.

Abstract
PURPOSE OF THE STUDY Various spine disorders are regularly treated by orthoses, and success of treatment depends on wearing these devices. In this study we examined the compliance, wear comfort, subjective stabilization and side effects associated with spinal orthoses using an individualized questionnaire and the Compact Short Form-12 Health Survey (SF-12). MATERIAL AND METHODS In this prospective pilot study of randomized cross-over design, twelve healthy volunteers with a mean age of 31.2 years wore three different types of orthoses, each for one week: A hyperextension brace (HB), a custom-made semirigid orthosis (SO) and a custom-made rigid orthosis (RO). The daily duration of wearing the orthosis was defined as primary endpoint; contentment was measured using an individualized questionnaire and the standardized SF-12. RESULTS In the study population calculated probability of wearing the HB and RO was between 0.2 und 38.5% (95% confidence interval). No volunteer wore the SO orthosis for the predefined time. The SO and RO each displayed high subjective stabilization, while the RO was more often associated with side effects like skin pressure marks than the SO. The need for rework due to discomfort was mainly necessary with the RO. We observed no substantial differences in feeling compression and sweating. Noteworthy, eight of 12 subjects complained of uncomfortable sternal pressure due to the upper pad of the HB. The SF-12: scores ranged from 52.1 to 48.6 on the physical (PCS), and from 53.7 to 50.8 on the mental component score (MCS), demonstrating an influence on QoL. DISCUSSION AND CONCLUSIONS The design as well as the orthosis itself influence the compliance of wearing and exert a moderate negative, but acceptable impact on QoL. The SO appeared to correlate with the best overall compromise between comfort and subjective stabilization. Further investigations are necessary in patients with spinal diseases, for whom the effect of orthosis wearing may surpass the potential discomfort. Key words: thoracolumbar spine, orthoses, SF-12 - Quality of Life - QoL, comfort, compliance.

Complications after surgical management of distal lower leg fractures. Scand J Trauma Resusc Emerg Med 2016; 24:146.

Abstract
BACKGROUND Osseous healing of distal lower leg fractures can be prolonged and is often associated with wound healing problems because of the marginal soft - tissue and vascular supply in this area. Postoperative complications are frequent, and according to the literature, open reduction and plate fixation is thought to be associated with higher complication rates. The objective of this study was to evaluate the most common postoperative complications following intramedullary nailing or plate osteosynthesis of distal lower leg injuries with a focus on combined tibio-fibular fractures. The outcomes of patients with and without complications associated the two surgical techniques were compared. METHODS During a 5-year period, all surgically treated distal tibiofibular fractures were retrospectively collected from the clinical database and were evaluated for the presence of postoperative complications which included compartment syndrome, wound infection, delayed union and non-union, synostosis and rotational malalignment. Postoperative complications were reviewed and correlated with patient risk factors. RESULTS A total of 199 patients were included in the study, and 75 complications were reported. The majority of complications were associated with closed fracture types treated with intramedullary nailing, delayed union being the most frequent. For open fractures, surgical treatment with plate fixation had a complication rate of 12% compared with 25% after intramedullary nailing. DISCUSSION In general, distal lower leg fractures are associated with a high risk of postoperative complications. Distal diaphyseal tibial fractures that have been treated with intramedullary nailing devices have a higher risk of delayed union or non - union. CONCLUSION Plate fixation in distal metaphyseal fractures has a higher risk of problems related to wound healing and postoperative wound infections.

Abstract
BACKGROUND Data of the TraumaRegister DGU® were analyzed to derive survival rates, neurological outcome and prognostic factors of patients who had suffered traumatic cardiac arrest in the early treatment phase. METHODS The database of the TraumaRegister DGU® from 2002 to 2013 was analyzed. The main focus of this survey was on different time points of performed resuscitation. Descriptive and multivariate analyses (logistic regression) were performed with the neurological outcome (Glasgow Outcome Scale) and survival rate as the target variable. Patients were classified according to CPR in the prehospital phase and/or in the emergency room (ER). Patients without CA served as a control group. The database does not include patients who required prehospital CPR but did not achieve ROSC. RESULTS A total of 3052 patients from a total of 38,499 cases had cardiac arrest during the early post-trauma phase and required CPR in the prehospital phase and/or in the ER. After only prehospital resuscitation (n = 944) survival rate was 31.7 %, and 14.7 % had a good/moderate outcome. If CPR was required in the ER only (n = 1197), survival rate was 25.6 %, with a good/moderate outcome in 19.2 % of cases. A total of 4.8 % in the group with preclinical and ER resuscitation survived, and just 2.7 % had a good or moderate outcome. Multivariate logistic regression analysis revealed the following prognostic factors for survival after traumatic cardiac arrest: prehospital CPR, shock, coagulopathy, thorax drainage, preclinical catecholamines, unconsciousness, and injury severity (Injury Severity Score). CONCLUSIONS With the knowledge that prehospital resuscitated patients who not reached the hospital could not be included, CPR after severe trauma seems to yield a better outcome than most studies have reported, and appears to be more justified than the current guidelines would imply. Preclinical resuscitation is associated with a higher survival rate and better neurological outcome compared with resuscitation in the ER. If resuscitation in the ER is necessary after a preclinical performed resuscitation the survival rate is marginal, even though 56 % of these patients had a good and moderate outcome. The data we present may support algorithms for resuscitation in the future.

Biomechanical investigation of a minimally invasive posterior spine stabilization system in comparison to the Universal Spinal System (USS). BMC Musculoskelet Disord 2016; 17:134. [PMID: 27005301 PMCID: PMC4804481 DOI: 10.1186/s12891-016-0983-1] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2015] [Accepted: 03/10/2016] [Indexed: 04/08/2023] Open
Abstract
Background Although minimally invasive posterior spine implant systems have been introduced, clinical studies reported on reduced quality of spinal column realignment due to correction loss. The aim of this study was to compare biomechanically two minimally invasive spine stabilization systems versus the Universal Spine Stabilization system (USS). Methods Three groups with 5 specimens each and 2 foam bars per specimen were instrumented with USS (Group 1) or a minimally invasive posterior spine stabilization system with either polyaxial (Group 2) or monoaxial (Group 3) screws. Mechanical testing was performed under quasi-static ramp loading in axial compression and torsion, followed by destructive cyclic loading run under axial compression at constant amplitude and then with progressively increasing amplitude until construct failure. Bending construct stiffness, torsional stiffness and cycles to failure were investigated. Results Initial bending stiffness was highest in Group 3, followed by Group 2 and Group 1, without any significant differences between the groups. A significant increase in bending stiffness after 20’000 cycles was observed in Group 1 (p = 0.002) and Group 2 (p = 0.001), but not in Group 3, though the secondary bending stiffness showed no significant differences between the groups. Initial and secondary torsional stiffness was highest in Group 1, followed by Group 3 and Group 2, with significant differences between all groups (p ≤ 0.047). A significant increase in initial torsional stiffness after 20’000 cycles was observed in Group 2 (p = 0.017) and 3 (p = 0.013), but not in Group 1. The highest number of cycles to failure was detected in Group 1, followed by Group 3 and Group 2. This parameter was significantly different between Group 1 and Group 2 (p = 0.001), between Group 2 and Group 3 (p = 0.002), but not between Group 1 and Group 3. Conclusions These findings quantify the correction loss for minimally invasive spine implant systems and imply that unstable spine fractures might benefit from stabilization with conventional implants like the USS.

Abstract
Fractures and dislocations of the cuneiform bones are rare injuries to the midtarsal foot. The injury severity is often unclear, and the prognostic factors are unknown. The purpose of the present study was to characterize our insights of the diagnostics, therapy, and fracture patterns. We questioned whether the number of involved cuneiform bones and the type of injury would affect the clinical outcome. With this information, we aimed to develop a classification system for injuries of the cuneonavicular joint. Five patients who had sustained complex fracture-dislocation of the cuneiform bones were prospectively registered, underwent surgery, and were followed. We reviewed the published data and found 47 reports that included 55 patients to improve the informative value of our study. The injury mechanisms and therapy were evaluated, and the postoperative limitations and pain were assessed. The clinical outcome was correlated with the number of involved cuneiforms and the fracture/dislocation pattern. Direct trauma was associated with isolated fracture, and indirect injury was associated with isolated dislocations. Occasionally, these injuries were overlooked on conventional radiographs, and closed reduction frequently failed. The number of cuneiform bones involved and the type of injury were shown to affect the clinical outcome. We devised an easily applicable classification system for injuries to the cuneiform bones using this information. All cases were classified as isolated fractures (1), isolated dislocations (2), or fracture-dislocations (3) involving 1 (A), 2 (B), or 3 (C) cuneiform bones. The classification system we propose will facilitate a better understanding of the fracture patterns at the cuneonavicular joint line and is a good prognostic tool that requires validation in clinical settings.

Biomechanical comparison of different external fixator configurations for stabilization of supracondylar humerus fractures in children. Clin Biomech (Bristol, Avon) 2016; 32:118-23. [PMID: 26743869 DOI: 10.1016/j.clinbiomech.2015.12.003] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2014] [Revised: 12/14/2015] [Accepted: 12/14/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND Currently, closed reduction and percutaneous pinning are considered the treatment of choice for displaced supracondylar humerus fractures. However, indications exist for the use of external fixation with Schanz screws. In this in vitro study, we evaluate the biomechanical properties of a new variation for external fixation and compare them to an established construct. METHODS Twenty distal cadaver humeri (10 pairs) were allocated to 2 groups. The humeri of the first group were fixed by an external fixator consisting of Schanz screws and an oblique K-wire inserted from the distal radial cortex of the humerus, those of the second group were fixed by a new variation with the oblique K-wire inserted from the distal ulnar cortex of the humerus. Displacement and stiffness in static loading in internal and external rotation, as well as in extension and flexion were evaluated and compared. FINDINGS The variation of the external fixator of the second group proved to be statistically significantly superior to the variation of the first group in internal rotation loading (p>0.05). In sagittal loading conditions and external rotation loading, the variations were equally stable (p>0.05). There was no significant effect of the samples' bone density on displacement and stiffness values in any direction of loading. INTERPRETATION In cases of pediatric supracondylar humerus fractures when an external fixator is used for osteosynthesis, the insertion of an additional ulnarly inserted anti-rotation K-wire should be preferred to a radially inserted one as it reduces secondary displacement of the distal fragment.

Abstract
INTRODUCTION Femoral shaft fractures in children are a common injury. Operative treatment is recommended for children above 3 years of age. The question of this investigation was the current clinical standard for the treatment of femoral shaft fractures in children under 3 years old. MATERIAL AND METHODS An e-mail questionnaire was sent to all clinics and hospital departments of the members of the German Society for Trauma Surgery and the German Society of Pediatric Surgery. RESULTS Out of 775 clinics and departments, 121 participated in the survey (16 %). From 2011 to 2012 overall 756 femoral shaft fractures of children 3 years and younger were treated of which 375 (50 %) were stabilized with elastic stable intramedullary nailing (ESIN), 183 (24 %) with an overhead extension, 178 (23 %) with a plaster cast and 9 (1 %) with external fixation. Finally, operative treatment was used in 51 % compared to 49 % with conservative treatment. DISCUSSION Obviously, operative treatment of femoral shaft fractures in children younger than 3 years is routinely used despite the fact that there is no evidential basis for this approach. There are good arguments for and against operative and conservative forms of treatment. Indications for operative treatment include multiple trauma, open fractures, body weight over 20 kg, child already free walking and lack of stable fixation with conservative treatment. To achieve more evidence for the existing recommendation of the American Academy of Orthopaedic Surgeons (AAOS) and the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF, Working Group of the Scientific Medical Specialist Societies), further investigations are needed.

Minimally invasive stabilization of distal humerus fractures: a pilot study with biomechanical evaluation. Technol Health Care 2015; 22:909-13.

Abstract
BACKGROUND Fracture of the distal humerus is a fairly rare injury and makes high demands on the treating surgeon. Prerequisites for a good outcome are anatomical reconstruction and osteosynthesis stable enough for exercises. A method permitting early restoration of function is especially important for patients with osteoporosis. The extensive surgical approach necessary for open reduction is associated with a high number of wound healing disorders and infections with a frequency of 11% being reported in the literature. Although open reduction and internal fixation in double-plating technique is unavoidable for complex intraarticular fractures, an alternative, minimally invasive and, consequently, tissue-preserving procedure is desirable for simpler fractures. OBJECTVE To investigate this issue further an angular stable nail system developed for the distal radius was implanted as a stabilizer and the construct tested biomechanically as part of a feasibility study. METHODS Distal humerus fractures were stabilized by insertion of a distal radius nail, namely, the Targon DR (Aesculap, Tuttlingen) and a K-wire. To test the hypothesis six cadaveric bones fixed in formalin were tested biomechanically for displacement, implant failure, and stiffness. Displacement was determined by means of an ultrasound-based system. RESULTS An average displacement of 1.6 mm ± 0.7 was recorded at a maximum compression force of 100 N in extension and an average displacement of 1.4 mm ± 0.9 in flexion. Implant failure was not observed for any of the constructs. CONCLUSIONS The study presented here permits the conclusion that a minimally invasive procedure is possible at the distal humerus and does ensure adequate stability. Although the nail was not specifically designed for the humerus, current findings form the basis for a promising approach that will be pursued further after modification of the nail design.

Abstract
Spinal canal stenosis is a dynamic phenomenon that becomes apparent during spinal loading. Current diagnostic procedures have considerable short comings in diagnosing the disease to full extend, as they are performed in supine situation. Upright MRI imaging might overcome this diagnostic gap.This study investigated the lumbar neuroforamenal diameter, spinal canal diameter, vertebral body translation, and vertebral body angles in 3 different body positions using upright MRI imaging.Fifteen subjects were enrolled in this study. A dynamic MRI in 3 different body positions (at 0° supine, 80° upright, and 80° upright + hyperlordosis posture) was taken using a 0.25 T open-configuration scanner equipped with a rotatable examination bed allowing a true standing MRI.The mean diameter of the neuroforamen at L5/S1 in 0° position was 8.4 mm on the right and 8.8 mm on the left, in 80° position 7.3 mm on the right and 7.2 mm on the left, and in 80° position with hyperlordosis 6.6 mm (P < 0.05) on the right and 6.1 mm on the left (P < 0.001).The mean area of the neuroforamen at L5/S1 in 0° position was 103.5 mm on the right and 105.0 mm on the left, in 80° position 92.5 mm on the right and 94.8 mm on the left, and in 80° position with hyperlordosis 81.9 mm on the right and 90.2 mm on the left.The mean volume of the spinal canal at the L5/S1 level in 0° position was 9770 mm, in 80° position 10600 mm, and in 80° position with hyperlordosis 9414 mm.The mean intervertebral translation at level L5/S1 was 8.3 mm in 0° position, 9.9 mm in 80° position, and 10.1 mm in the 80° position with hyperlordosis.The lordosis angle at level L5/S1 was 49.4° in 0° position, 55.8° in 80° position, and 64.7 mm in the 80° position with hyperlordosis.Spinal canal stenosis is subject to a dynamic process, that can be displayed in upright MRI imaging. The range of anomalies is clinically relevant and dynamic positioning of the patient during MRI can provide essential diagnostic information which are not attainable with other methods.

Outcome and risk factors in children after traumatic cardiac arrest and successful resuscitation. Resuscitation 2015; 96:59-65. [PMID: 26232515 DOI: 10.1016/j.resuscitation.2015.07.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2015] [Revised: 06/09/2015] [Accepted: 07/20/2015] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Prospective collected data of the TraumaRegister DGU(®) were analyzed to derive survival rates and predictors for non-survival in the children who had suffered traumatic cardiorespiratory arrest. Different time points of resuscitation efforts (only preclinical, in the emergency room (ER) or preclinical+ER) were analyzed in terms of mortality and neurological outcome. METHODS The database of the TraumaRegister DGU(®) comprising 122,742 patients from 1993 to 2013 was analyzed. The main focus of this survey was on the paediatric group defined by an age ≤ 14 years who could be compared to adults. Different statistical analysis (univariate and multivariate analysis, logistic regression) were performed with mortality as the target variable. Differences between the paedatric group and adults were analysed by Fisher's exact test. RESULTS Data after preclinical and/or ER resuscitation from 152 children and 1690 adults were analyzed. A good or moderate outcome (GOS 5+4) was found in 19.4% of the children's group compared to 12.4% of the adults (p=0.02). Analysis of the GOS 5+4 subgroups after preclinical resuscitation only revealed that these outcomes were achieved by 19.4% of the paediatric group and 13.2% of the adults (p=0.24), after ER-only resuscitation by 37.0% of the children and 19.6% of the adults (p=0.046), and after preclinical and ER resuscitation by only 10.9% of the children compared to 2.5% of the adults (p=0.006). Taking only survivors into account, 84.8% of the children and 62% of the adults had a GOS 4+5. The highest risk for mortality in the logistic regression model was associated with preclinical intubation, followed by GCS 3, blood transfusion and severe head injury with AIS ≥3 and ISS. CONCLUSIONS CPR in children after severe trauma seems to yield a better outcome than in adults, and appears to be more justified than the current guidelines would imply. Resuscitation in the ER is associated with better neurological outcomes compared with resuscitation in a preclinical context or in both the preclinical phase and the ER. Our children's outcomes seem to be better than those in most of the earlier studies, and the data presented might support algorithms in the future especially for paediatric resuscitation.

Abstract
BACKGROUND A common method to restore the sagittal alignment and stabilize the spinal column is a dorso-ventral spondylodesis. It is assumed that correction loss after posttraumatic spondylodesis results from inadequate incorporation of the autologous iliac crest graft. MATERIALS AND METHODS Retrospective documentation of patients with unstable vertebral body fractures of the thoracic or lumbar spine with concomitant rupture of at least one adjacent intervertebral disk who received surgical treatment at our institution from 2000 to 2006. Followed by analysis of the computer tomography documentation of a total of 142 patients with unstable vertebral body fracture stabilized by posterior internal fixator and anterior iliac crest spondylodesis. RESULTS The following mean angle changes were derived from the second series of CT scans performed on average 283 days after anterior spondylodesis: vertebral wedge angle (VWA): 2.1°; segmental kyphotic angle: 4.9°; adjusted-SKA: 4.8°; sagittal index (SI): -0.04; segmental-scoliotic-angle (SSA): 0°; adjusted-SSA: 0°. Changes in VWA, both SKAs and SI postoperatively and prior to ME, were statistically significant (P<0.05). The McAfee fusion assessment of the graft showed: full fusion: cranial 64%, caudal 47%; partial fusion: cranial 20.5%, caudal 29%; lysis: cranial 8.5%, caudal 17%; graft resorption: 7%. No correlation was found between the above-mentioned angle changes and fusions grade. DISCUSSION The importance of radiological evidence of fusion deficiency is questionable, because the extent of fusion only has a minimal effect on correction loss. LEVEL OF EVIDENCE Level IV.

Management of femoral shaft fractures. ACTA CHIRURGIAE ORTHOPAEDICAE ET TRAUMATOLOGIAE CECHOSLOVACA 2015; 82:22-32. [PMID: 25748658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/04/2023]
Abstract
Femoral shaft fractures are severe injuries and are often associated with a high impact trauma mechanism, frequently seen in multiple injured patients. In contrast an indirect trauma mechanism can lead to a complex femoral shaft fracture especially in elderly patients with minor bone stock quality. Hence management of femoral shaft fractures is often directed by co-morbidities, additional injuries and the medical condition of the patient. Timing of fracture stabilization is depended on the overall medical condition of the patient, but definite fracture fixation can often be implemented in the early total care concept in management of multiple injured patients. The treatment of choice is intramedullary fracture fixation. Further development of existing intramedullary nailing systems now offer comfortable handling and different locking options. Ipsilateral fractures of the neck and shaft are therefore facilitated in management. Then again increasing numbers of obese patient are representing a new patient group with challenging co-factors in fracture management. Sufficient preoperative planning is helpful to choose the most adequate fixation device. Correct reduction of the fracture and perioperative control of the axis and rotation is mandatory to avoid postoperative malrotation, which still represents the most frequent complication.

Abstract
Due to the elbow joint's complex functional anatomy, the multifragmentary nature of many fractures and concomitant destabilizing associated injuries, dislocated fractures of the radial head and neck still present a serious challenge for the orthopedic surgeon. Thorough knowledge of the elbow's anatomy and biomechanics is essential to analyze and understand the injury and plan its treatment. The aim of a differentiated therapy approach is to restore the joint's anatomy and kinetics, stable and painless joint function, and to avoid or at least delay posttraumatic joint changes. The degree of dislocation, stability of fragments, size and number of fractured joint surfaces and associated bony and ligamentous injuries (and the instability they incur) must be addressed in the therapy regimen. There are various treatment options depending on the injury's classification, i.e. a Mason I fracture is treated conservatively, while more severe injuries may require osteosynthesis and endoprosthesis. There is a lack of clear therapy recommendations based on solid evidence regarding Mason classification types III-IV. In particular expert opinions diverge and study results are inconsistent. Especially the value of radial head arthroplasty is still hotly debated. Key words: radial head fracture, radial head prosthesis, radial neck fracture, Mason classification, radial head arthroplasty, elbow injury.

Is Whole-Body Computed Tomography the Standard Work-up for Severely-Injured Children? Results of a Survey among German Trauma Centers.

Abstract
PURPOSE OF THE STUDY Whole-body computed tomography is accepted as the standard procedure in the primary diagnostic of polytraumatised adults in the emergency room. Up to now there is still controversial discussion about the same algorithm in the primary diagnostic of children. The aim of this study was to survey the participation of German trauma-centres in the care of polytraumatised children and the hospital dependant use of whole-body computed tomography for initial patient work-up. MATERIAL AND METHODS A questionnaire was mailed to every Department of Traumatology registered in the DGU (German Trauma Society) databank. RESULTS We received 60,32% of the initially sent questionnaires and after applying exclusion criteria 269 (53,91%) were applicable to statistical analysis. In the three-tiered German hospital system no statistical difference was seen in the general participation of children polytrauma care between hospitals of different tiers (p = 0.315). Even at the lowest hospital level 69,47% of hospitals stated to participate in polytrauma care for children, at the intermediate and highest level hospitals 91,89% and 95,24% stated to be involved in children polytrauma care, respectively. Children suspicious of multiple injuries or polytrauma received significantly fewer primary whole-body CTs in lowest level compared to intermediate level hospitals (36,07% vs. 56,57%; p = 0.015) and lowest level compared to highest level hospitals (36,07% vs. 68,42%; p = 0.001). Comparing the use of whole-body CT in intermediate to highest level hospitals a not significant increase in its use could be seen in highest level hospitals (56,57% vs. 68,42%; p = 0.174). CONCLUSION According to our survey, taking care of polytraumatised children in Germany is not limited to specialised hospitals or a defined hospital level-of-care. Additionally, there is no established radiologic standard in work-up of the polytraumatised child. However, in higher hospital care -levels a higher percentage of hospitals employs whole-body CTs for primary radiologic diagnostics in polytraumatised children.

Abstract
For the treatment of distal humerus an approach involving olecranon osteotomy is frequently preferred as it offers a clearer view, especially in cases of complex intraarticular fractures. It is however associated with the high risk of osteotomy-related complications such as nonunion, delayed healing, implant failure and migration of wires. The aim of the present study was to evaluate the stability of different new procedures that stabilize olecranon osteotomy compared with conventional tension band wiring. We hypothesize that the new implants provide equivalent stability as the conventional tension band wiring. To test the hypothesis 27 biomechanically evaluated synthetic ulnae were osteotomized and stabilized with either the application of tension band wiring, the Olecranon Hook LCP (Synthes, Switzerland), or the Olecranon Osteotomy nail (Synthes, Switzerland). Loading was performed providing a tensile load to simulate the tensile force applied by the triceps muscle. Cyclic force-controlled loading was performed at 300 alternating forces between 10N and 500N at a speed of 200N/sec. An ultrasound-based system measured displacement to an accuracy of 0.1 mm. Statistical analysis showed significantly less displacement in the Olecranon Hook LCP and Olecranon Osteotomy nail groups compared with tension banding. Comparison of plate and nail yielded no differences in stability. Biomechanical testing did however show significantly higher stability for newer fixation methods for olecranon osteotomies compared with the frequently applied technique of tension band wiring. Whether the use of these implants will also lower complication rates remains to be evaluated in future clinical studies. Level of evidence: Basic Science Study, Biomechanical Study.

Abstract
Standard procedure for monosegmental anterior spondylodesis often combines anterior stabilization with autologous iliac crest graft. Recent publications defined a minimum size of the graft as a technical specification for this procedure. The cross sectional area of the graft to be transplanted should be at least 23.9% of the cross sectional area of the vertebral bodies to be fused. We investigated whether the required minimum size of autologous graft, as identified both experimentally and clinically, is compatible with the anatomical conditions in central european patients. Computed tomography scans (n = 348) of polytraumatized patients were obtained in the course of initial diagnosis. The scans were evaluated for vertebral body size and the possible size of autologous bone graft in the region of the anterior superior iliac crest. The evaluation of 348 CT scans demonstrated that 95% of the quantified iliac crest grafts would achieve the size recommended for anterior spinal fusion between T10 and T12. In 90% of all cases the planned iliac crest graft exceeded the size limit of 23,9% between concerning the endplates T10 and L2. In 85% the planned iliac crest graft exceeded the size limit of 23,9% between T10 and L3. The recommendation to take this value into account for monosegmental anterior spondylodesis should gain in importance in clinical practice.

Abstract
Patient safety became paramount in medicine as well as in emergency medicine after it was recognized that preventable, adverse events significantly contributed to morbidity and mortality during hospital stay. The underlying errors cannot usually be explained by medical technical inadequacies only but are more due to difficulties in the transition of theoretical knowledge into tasks under the conditions of clinical reality. Crew Resource Management and Human Factors which determine safety and efficiency of humans in complex situations are suitable to control such sources of error. Simulation significantly improved safety in high reliability organizations, such as the aerospace industry.Thus, simulator-based team training has also been proposed for medical areas. As such training is consuming in cost, time and human resources, the question of the cost-benefit ratio obviously arises. This review outlines the effects of simulator-based team training on patient safety. Such course formats are not only capable of creating awareness and improvements in safety culture but also improve technical team performance and emphasize team performance as a clinical competence. A few studies even indicated improvement of patient-centered outcome, such as a reduced rate of adverse events but further studies are required in this respect. In summary, simulator-based team training should be accepted as a suitable strategy to improve patient safety.

Abstract
Most proximal humeral fractures affect elderly patients and can be treated nonoperatively with good functional outcomes.The treatment of displaced three and four-part fractures remains controversial and depends on a variety of underlying factors related to the patient (e.g., comorbidity, functional demand), the fracture (e.g., osteoporosis), and the surgeon (e.g., experience).Throughout the literature, open reduction and locking plate osteosynthesis is associated with considerable complication rates, particularly in the presence of osteoporosis.Low local bone mineral density, humeral head ischemia, residual varus displacement, insufficient restoration of the medial column, and nonanatomic reduction promote failure of fixation and impair functional outcome.The outcome of hemiarthroplasty is closely related to tuberosity healing in an anatomic position to enable the restoration of rotator cuff function. Reverse shoulder arthroplasty may provide satisfactory shoulder function in geriatric patients with preexisting rotator cuff dysfunction or after the failure of first-line treatment.

Abstract
Rotator cuff ruptures are the most common degenerative tendon injury and occur mainly in older patients as multifactorial disorders manifesting the main symptoms of pain and restricted range of motion. Thorough clinical examination of the shoulder includes testing the function of the rotator cuff and leads to a tentative clinical diagnosis that is the prerequisite for diagnostic imaging procedures. Sonography of the shoulder gives rapid access to a very good sensitive overview of the rotator cuff. Conventional radiological imaging permits differential diagnosis since a reduced acromiohumeral interval is understood as a direct sign of rotator cuff rupture. The gold standard in imaging diagnostics is MRI because it not only delivers images of rotator cuff defects, but also permits interpretation of degenerative changes in the musculature. Significant pain relief can be achieved by conservative therapy such as analgesia, manual therapy and physiotherapeutic exercises and leads to improvements in the active range of motion. Persistent pain or progressive pain during conservative therapy are indications for surgical intervention. Arthroscopy-assisted treatment is tissue friendlier than open surgery and is today considered the standard for surgical treatment of rotator cuff rupture because of higher patient acceptance. Recent studies report that surgical rotator cuff repair leads to significant improvement in function, pain relief, and greater patient satisfaction. The principles of postoperative care after surgical rotator cuff repair are immobilization and gradual loading with passive and active exercises.

Distal tibial fractures and pilon fractures. ACTA CHIRURGIAE ORTHOPAEDICAE ET TRAUMATOLOGIAE CECHOSLOVACA 2014; 81:167-176.

Abstract
Fractures of the distal tibia are often very severe injuries that generally occur in the context of high-energy trauma and present with significant concomitant soft tissue involvement. Open fractures and extensive destruction of the articular surfaces are important challenges to the treating surgeon. In consequence the outcome for distal meta- and epiphyseal tibial fractures depends largely on the severity of the soft tissue injury and its management. Conventionally, tibial pilon fractures require surgical intervention. Conservative treatment would only be considered in some exceptional cases, for example, inoperability of the patient. Controversial discussion of optimal surgical technique and optimal timing of surgery is ongoing. There is broad consensus that soft tissue consolidation must have first priority as this is the basis for both fracture healing and good long-term outcomes. Surgical intervention can be managed as a one-stage or multi-stage procedure to achieve internal or external fracture fixation.

Abstract
The patellar bone is involved in repetitive, load bearing motion sequences every day and functions as a vectorial force translator. A fracture rate of 1% of all skeletal fractures is reported and surgical treatment often required. beside a direct trauma mechanism, indirect mechanism but as well as fatigue fractures after reconstructive knee surgery are published. The fracture management is dependent on the soft tissue condition and a variety of surgical options are known. new generation of low profile plates show promising results but the conventional cerclage wiring technique with K-wires is widely preferred. best functional results with sustainable stability are biomechanically seen after a combined fixation technique using anterior cerclage wiring with cannulated screw fixation. A definite algorithm of treatment of patellar bone fractures is yet not defied but a review of classification and surgical techniques should give assistance in decision making.

Abstract
INTRODUCTION There is no consensus on optimal treatment strategy for Mason type II-IV fractures. Most recommendations are based upon experts' opinion. METHODS An OVID-based literature search were performed to identify studies on surgical treatment of radial head and neck fracture. Specific focus was placed on extracting data describing clinical efficacy and outcome by using the Mason classification and including elbow function scores. A total of 841 clinical studies were identified describing in total the clinical follow-up of 1264 patients. RESULTS For type II radial head and neck fractures the significant best treatment option seems to be ORIF with an overall success rate of 98% by using screws or biodegradable (polylactide) pins. ORIF with a success rate of 92% shows the best results in the treatment of type III fractures and seem to be better than resection and implantation of a prosthesis. For this fracture type the ORIF with screws (96%), biodegradable (polylactide) pins (88%) and plates (83%) showed the best results. In the treatment of type IV fractures similar results could be found with a tendency of the best results after ORIF followed by resection and implantation of a prosthesis. If a prosthesis was implanted, the primary implantation seems to be associated with a better outcome after type III (87%) and IV (82%) fractures compared to the results after a secondary implantation. DISCUSSION Recommendations for surgical treatment of radial head and neck fractures according to the Mason classification can now be given with the best available evidence. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To evaluate influence of variation in spatio-temporal resolution and scan-rescan reproducibility on three-dimensional (3D) visualization and quantification of arterial and portal venous (PV) liver hemodynamics at four-dimensional (4D) flow MRI. METHODS Scan-rescan reproducibility of 3D hemodynamic analysis of the liver was evaluated in 10 healthy volunteers using 4D flow MRI at 3T with three different spatio-temporal resolutions (2.4 × 2.0 × 2.4 mm(3), 61.2 ms; 2.5 × 2.0 × 2.4 mm(3), 81.6 ms; 2.6 × 2.5 × 2.6 mm(3), 80 ms) and thus different total scan times. Qualitative flow analysis used 3D streamlines and time-resolved particle traces. Quantitative evaluation was based on maximum and mean velocities, flow volume, and vessel lumen area in the hepatic arterial and PV systems. RESULTS 4D flow MRI showed good interobserver variability for assessment of arterial and PV liver hemodynamics. 3D flow visualization revealed limitations for the left intrahepatic PV branch. Lower spatio-temporal resolution resulted in underestimation of arterial velocities (mean 15%, P < 0.05). For the PV system, hemodynamic analyses showed significant differences in the velocities for intrahepatic portal vein vessels (P < 0.05). Scan-rescan reproducibility was good except for flow volumes in the arterial system. CONCLUSION 4D flow MRI for assessment of liver hemodynamics can be performed with low interobserver variability and good reproducibility. Higher spatio-temporal resolution is necessary for complete assessment of the hepatic blood flow required for clinical applications.

Abstract
PURPOSE Autologous chondrocyte implantation (ACI) is a well-established treatment method for cartilage defects in knees. Age-related grouping was based on expression data of cartilage-specific markers. Specificities of ACI in the different populations were analysed. METHODS Two hundred and sixty-seven patients undergoing ACI in the knee between 2006 and 2010 were included in this analysis. Cell characteristics and expression data of cartilage-specific surface markers as CD44, aggrecan and collagen type II were statistically analysed for age association. Epidemiological data of the defined groups were compared. Course of treatment was evaluated using MRI. RESULTS A correlation analysis showed statistically significant associations between age and aggrecan or collagen type II expression in all patients <30 years. A cluster analysis could predict age-dependent expression of these markers separating groups with an average age of 18.1 ± 2.3 and 23.6 ± 4.2 years, respectively (p < 0.02). Discriminance analysis suggested the age border between adults and juveniles at about 20 years. There was no influence of age on cell characteristics or CD44 expression. In the 19 of 267 patients with an age ≤18 years, gender distribution was not different compared to adults, but patella was significantly more affected. Cartilage lesions were mainly caused by osteochondritis dissecans (OCD) and trauma. The Knee Osteoarthritis Scoring System in MRI reached 4.8 ± 2.3 points before, declining to 3.3 ± 2.3 points 6 and 12 months after the operation. CONCLUSIONS Age-related expression of cartilage-specific markers allows definition of adolescents in cartilage regenerating surgery. Chondromalacia in these patients is mainly caused by OCD or trauma. LEVEL OF EVIDENCE Case series, Level IV.

Abstract
The aim of this study was to present an analysis of acetabular fractures during childhood as compared to those in adults. Within a multicenter register study, data of 3 time periods (1991-93, 1998-2000, 2004-2008) were pooled and analyzed for incidence, epidemiology, classification, outcome and treatment of acetabular fractures in children (< 15 years). One hundred fifty three children (2.1%) among 7360 patients with pelvic fractures were included in the study. Only 15 children sustained an acetabular fracture (9.8%). Simple fracture types according to Letournels' classification were more frequent in paediatric patients (p < 0.01), receiving less often operative treatment. Multiple injuries were present in 36% of children, the average Injury Severity Score (ISS) of all children was 17 points. Clinical results were good with an average Merle d'Aubigné score of 16.4 points and a Karnofsky performance of 90%. Fractures of the acetabulum in childhood remain a rare injury with distinct fracture characteristics, usually caused by high impact accidents.

Abstract
Introduction This systematic review is focused on the in-hospital mortality and neurological outcome of survivors after prehospital resuscitation following trauma. Data were analyzed for adults/pediatric patients and for blunt/penetrating trauma. Methods A systematic review was performed using the data available in Ovid Medline. 476 articles from 1/1964 - 5/2011 were identified by two independent investigators and 47 studies fulfilled the requirements (admission to hospital after prehospital resuscitation following trauma). Neurological outcome was evaluated using the Glasgow outcome scale. Results 34 studies/5391 patients with a potentially mixed population (no information was found in most studies if and how many children were included) and 13 paediatric studies/1243 children (age ≤ 18 years) were investigated. The overall mortality was 92.8% (mixed population: 238 survivors, lethality 96.7%; paediatric group: 237 survivors, lethality 86.4% = p < 0.001). Penetrating trauma was found in 19 studies/1891 patients in the mixed population (69 survivors, lethality: 96.4%) and in 3 pediatric studies/91 children (2 survivors lethality 97.8%). 44.3% of the survivors in the mixed population and 38.3% in the group of children had a good neurological recovery. A moderate disability could be evaluated in 13.1% in the mixed population and in 12.8% in children. A severe disability was found in 29.5% of the survivors in the mixed patients and in 38.3% in the group of children. A persistent vegetative state was the neurological status in 9.8% in the mixed population and in 10.6% in children. For each year prior to 2010, the estimated log-odds for survival decreased by 0.022 (95%-CI: [0.038;0.006]). When jointly analyzing the studies on adults and children, the proportion of survivors for children is estimated to be 17.8% (95%-CI: [15.1%;20.8%]). The difference of the paediatric compared to the adult proportion is significant (p < 0.001). Conclusions Children have a higher chance of survival after resuscitation of an out-of-hospital traumatic cardiac arrest compared to adults but tend to have a poorer neurological outcome at discharge.

Abstract
Fractures of the humeral shaft are less frequent than those of the proximal humerus. The formerly recommended treatment of humeral shaft fractures was conservative according to Böhler. This still remains an adequate concept of treatment but according to a change in the technical possibilities and the demands of patients and physicians on fast restoration of function and low pain, there is a trend towards surgical stabilization of humeral shaft fractures. The implant of choice is discussed controversially and consists of various types of nails versus plating. The technique of nailing is antegrade or retrograde and depends on the localization of the fracture. In our opinion good indications for plating are combined fractures of the proximal humerus and the shaft as well as very distal humeral shaft fractures. A primary lesion of the radial nerve is no imperative indication for exploration and different studies have shown the same results for exploration after 2 or 3 months if there is no spontaneous remission.

Abstract
Fractures of the proximal humerus commonly affect elderly patients. The vast majority of proximal humeral fractures result from low-energy trauma in presence of osteoporosis. Incidence of proximal humeral fractures dramatically increased over the last decades. Recent epidemiological studies expect a rather stagnant incidence. Diversity of fracture types attenuates reliability of available classification systems. Even though, predictive morphologic criteria have been detected enabling a prognostic assessment. A short or absent metaphyseal head extension and disruption of the medial periosteal hinge reliably predict ischemia of the humeral head fragment. Still, humeral head necrosis may be prevented in early reduction and fixation. The range of treatment options consists of non-operative therapy, minimal-invasive osteosynthesis, open reduction and plate fixation, intramedullary nailing and primary arthroplasty. Most proximal humeral fractures in the elderly are stable injuries and can be successfully treated by non-operative means. Operative treatment of displaced, unstable fractures should resort to the least invasive procedure providing adequate reduction and fixation stability. To date, open reduction and locking plate osteosynthesis represents the standard operative procedure in displaced three- and four-part fractures. However, a number of risk factors may promote fixation failure or impair functional outcome, most important low local bone mineral density, residual varus displacement of the humeral head, insufficient restoration of medial calcar support, humeral head ischemia and insufficient fracture reduction. Innovation of fixation techniques (e. g. angular stable locking systems and bone augmentation) will further expand indications for operative fracture treatment. Outcome of hemiarthroplasty is closely related to anatomical tuberosity healing and restoration of rotator cuff function. Reverse shoulder arthroplasty may provide satisfactory shoulder function in geriatric patients, rotator cuff dysfunction or failure of first-line treatment. Choice of treatment should be individualized and base on careful evaluation of patient-specific, fracture-specific and surgeon-specific aspects.

Tibial shaft fractures - management and treatment options. A review of the current literature. ACTA CHIRURGIAE ORTHOPAEDICAE ET TRAUMATOLOGIAE CECHOSLOVACA 2012; 79:499-505.

Abstract
Treatment of tibial shaft fractures is still discussed controversial. In the present study current literature was reviewed with the objective to demonstrate current recommendations concerning tibial shaft fractures. Tibial shaft fractures are often caused by high-energy trauma with severe concomitant soft-tissue injuries. Solid bone union without hypertrophy, fast mobilization and full range of motion without further soft-tissue damages are the aims of the therapy. Non-displaced tibial shaft fractures in patients with good compliance can be treated conservatively. Deep venous thrombosis, compartment syndrome, soft tissue injury and chronic regional pain syndrome are the major risks of conservative treatment and need to be required. Operative treatment can be performed with several different implants. Intramedullary nailing with a huge biomechanical stability seems to be the implant of choice. Only rare indications for plate osteosynthesis can be found. The use of external fixation has declined even though external fixation is still the implant of choice in first line treatment of multiple trauma according to the damage control principles. Open fractures with precarious blood supply and weak soft tissue covering are vulnerable to complications and remain a challenge for every treating surgeon. Reconstruction of axis, length and rotation is essential for a good outcome. The choice of technique depends on fracture localization, type of fracture, history of concomitant disorders and soft tissue damage.

Abstract
Polytrauma is a rare diagnosis in childhood. Even after high-energy accidents isolated injuries of the skull and brain or extremities are more common. Injury is still the most frequent cause of death in childhood in industrialized countries. The lethality of polytraumatized children is about 19%. Injuries of the extremities do not play such an important role for the survival of polytraumatized children but for the definitive outcome. The diagnostic algorithm for polytraumatized children is related to adults and includes spiral computed tomography in the emergency room. Plain radiographs are still the gold standard for the diagnostic workup of fractures. Generally therapeutic approaches in the treatment of fractures in children are often conservative. Because of the special situation in polytrauma with ICU care and the need for venous catheters, fast mobilization and positioning in bed, indications for operative treatment and definitive stabilization of fractures are required for polytraumatized children.

Abstract
PURPOSE OF THE STUDY Surgical techniques for the treatment of supracondylar fractures in children are repeatedly the subject of discussion. The aim of the present study was to compare experience with the technique of crossed Kirschner wires at our own hospital with current literature. PATIENTS AND METHODS In the period from 2000-2006 a total of 86 children aged 1.7 to 12.7 years were treated by means of crossed K-wire osteosynthesis. Follow up was conducted at an average of 32 months. Outcomes were evaluated based on von Laer's criteria. RESULTS Reported complications were migration of the K-wires in 7% of cases and secondary dislocation and re-operation in 4% of cases. Lesion of the radial nerve was diagnosed postoperatively in two cases. Hospital stay was 1.5 days on average. Postoperative immobilization in an upper arm splint and implant removal after 6 weeks on average. 57% of the children received physiotherapy during the course of treatment. Slight varization was found in 11% of children and an unsatisfactory range of motion in 13%. Satisfactory outcomes were recorded for 83% of patients. CONCLUSION K-wire osteosynthesis is associated with a low complication rate and continues to be a safe standard procedure for the stabilization of supracondylar humerus fractures. Key words: supracondylar humerus fracture, Kirschner wires, paediatric fractures.

Abstract
Clavicle fractures, especially of the mid third, are an injury commonly seen in clinical practice, therefore, there is constant earnest discussion of the optimal approach to therapy. Until recently clavicle fractures were solely the domain of non surgical management. Even displaced fractures have been successfully managed without surgery. However, complications have been reported after non surgical treatment, the most frequent being post-traumatic shortening of the clavicle with varying functional consequences for the shoulder joint and range of arm motion as well as pseudarthrosis, especially after more severely displaced fractures. Recent studies have now shown that outcomes after non surgical management of displaced fractures or shortening of the clavicle are worse than had been previously assumed. Surgical techniques for the stable fixation of clavicle fractures have been improved and a wider selection of implants for osteosynthesis of these fractures has become available. Although there is widespread consensus that undisplaced or minimally displaced clavicle fractures respond well to non surgical management, optimal treatment of displaced fractures or severe shortening is under scrutiny with regard to both the basic choice between non surgical or surgical management and implant selection. According to current research findings, surgical management of displaced clavicle fractures has advantages and appears to be superior to non surgical management. Intramedullary nailing has proven suitable for simple straight fractures, and plate fixation for multifragmentary fractures.

Abstract
Humeral shaft fractures account for about 1-3% of all fractures. These fractures are regarded as the domain of non-surgical management. This is certainly still the contemporary view but there is an obvious trend towards surgical stabilization. Surgical treatment of humeral shaft fractures has nonetheless been greatly facilitated by the development of new implants. In particular, a new generation of nails that general permit immediate mobilization have become available for improved management of longitudinal and multi-segmental fractures. Retrograde and antegrade nails have advantages and disadvantages and selection procedure is often based on the distal or proximal location of the fracture. Plates also offer an alternative for certain indications and have advantages at the proximal and distal shaft in particular. If there is primary lesion of the radial nerve, exploration is not very advisable, but in the absence of remission exploration can be conducted after several months with the same degree of success. Since the published literature offers no comparative studies with a high level of evidence, our statement can only be regarded as an up-to-date recommendation in the hope that future prospective randomized studies will address this issue.

Abstract
PURPOSE OF THE STUDY Fractures affecting a partially closed physis are described as transitional fractures. The distal tibia is one of the most common locations for transitional fractures second only to the distal radius. Aim of this retrospective study was to evaluate the clinical and radiological results after surgical treatment of transitional fractures of the distal tibia. PATIENTS AND METHODS From May 2003 to March 2009 24 children (median age 14 years) received surgical treatment for transitional fractures of the distal tibia. 89% (21/24) of patients were followed up after 27.5 (range 6 to 72) months to assess functional out come (using the AO Foot and Ankle Score). RESULTS Nine girls and 15 boys were included in the study with the girls being younger on average (12.4 ± 0.9 vs. 14.3 ± 1.1 years, p = 0.00013). Two-plane fractures were present in 4 cases, 15 and 5 children sustained tri-plane I and II fractures, respectively. Median preoperative fracture displacement was measured at 4 mm (range 3 to 11 mm). Traumatic supination of the ankle joint during sports activities was the predominant injury mechanism (18/24 cases) followed by bicycle or motorbike accidents (6/24). A satisfactory reduction (1 mm or less) was achieved in all but one patient. In this case revision surgery was necessary to restore anatomical reduction. No perioperative complications occurred in the remaining 23 cases. Metal implants were removed upon fracture consolidation after 8.2 ± 6.7 months. At the time of follow-up none of the children were impaired in activities of daily living and there were no restrictions in sporting activity. All patients sco- red good or excellent results on the AO Foot and Ankle Score. DISCUSSION Surgical stabilization can be recommended as a safe and effective treatment strategy in displaced transitional fractures of the distal tibia and will lead to good or excellent mid term results.

Abstract
INTRODUCTION The effective initial treatment in the emergency room of polytraumatized children requires a sound knowledge of com- mon injury patterns, incidence, mortality, and consequences. The needed initial radiological imaging remains controversial and should be adapted to the expected injury pattern. PATIENTS AND METHODS In this retrospective study, the injury patterns of 56 polytraumatized paediatric patients (age ≤ 16 years) in the period from December 2001 to May 2009 were evaluated. All children were initially diagnosed with a whole body CT scan. The cause of accident, the localization including the detailed diagnose, the lethality and the severity of the injuries were analyzed. The AIS (Abbreviated Injury Scale) and ISS (Injury Severity Score) were used to classify the severity of injuries in different body regions. Moreover the number and the kind of operation as a consequence of the initial made diagnoses were investigated. RESULTS The mean ISS was 30 ± 13 in 38 boys and 18 girls with a mean age of 10 years. The lethality was 13% and 4% in the first 24 hours. The most severe and most frequent injury was craniocerebral trauma in 89% with an AIS ≥ 3 in 80%. Surgical intervention of the head was done in 41%. Thorax injuries were found in 63% with 57% with an AIS ≥ 3 and in 11% a thoracic drainage was needed. Abdominal trauma was found in 34% (surgery 4%) with an AIS ≥ 3 in 32%. Fractures of the spine occurred in 14% (surgery 5%) with an AIS ≥ 3 in 4% and pelvic injuries were diagnosed in 16% (surgery 4%) with an AIS ≥ 3 in 14%. Injuries of the upper extremity were found in 23% (surgery 11%) with an AIS ? 3 in 5% and of the lower extremity in 32% (surge- ry 16%) with an AIS ≥ 3 in 13%. CONCLUSION The authors recommend a whole body CT scan in children who are potentially polytraumatized because of the detected high percentage of head and thorax injuries in polytraumatized children and the needed head surgery. The quickest imaging with a high sensitivity is the whole body CT scan which provides the clinicians with relevant information to initiate life-saving therapy.
