RESUMEN
PURPOSE: Olecranon fractures are particularly vulnerable to distraction and subsequent fracture dislocation due to the high tensile forces. Surgical treatment aims at reducing the fracture and restoring the anatomical joint surface condition, as well as neutralizing the strain inhibiting fracture healing. The XS nail® (Intercus GmbH, Bad Blankenberg, Germany), an intramedullary implant exerting compression across the entire fracture surface, unlike plates, leaves a minimal extra-cortical profile, and can be secured with threaded locking wires, thereby retaining the anatomical reduction without displacement or steps within the articular surface, which was often found in tension band wiring. After encouraging initial results, the long-term outcome was assessed. METHODS: This retrospective study evaluated the long-term outcome of patients surgically treated at our trauma center between January 2002 and December 2005 using the XS nail®. Patients over the age of 18 years eligible for the study must have undergone surgery for isolated, recent (less than 14 days) traumatic olecranon fractures, without concomitant injuries to the ipsilateral elbow and forearm. Further exclusion criteria were pseudarthrosis, re-fractures and osteotomy for distal humerus surgery, as well as polytraumatized patients unable to aid in their own recovery. Data were retrospectively gathered by standardised questionnaire and patient records, as well as surgery and anesthesiology reports. Data analysis was performed using Microsoft Office Excel® 2016. RESULTS: There were 32 patients, 13 males (mean age 49.0 years) and 19 females (mean age 68.9 years) with 11 Schatzkers type D, 7 each type A and C, 5 type B and 2 type E at an average of 55.2 months, all showing complete consolidation. Of them, 6 patients had a loss of range of motion with more than 10° in the sagittal plane, and only 1 patient exceeded 10° reduction of supination. Twenty-five patients reported being pain-free under all circumstances, and all but 2 patients (93.75%) had returned to their previous activity level. The average disabilities of the arm, shoulder and hand score was 21.15 (range 0-88.3), and the overall Mayo elbow performance index was 91.87, without complications, such as wound infection, neurovascular impairment or premature hardware removal. CONCLUSION: Using the XS nail® system, all fracture types can be successfully treated and the rate of complications was lower than that treated by standard methods published in current literature. An excellent functional outcome, high range of motion as well as good retention of reduction without soft tissue irritation makes this a very suitable implant for fractures subject to tension.

A case of in-hospital thoracotomy with subsequent open chest cardiopulmonary resuscitation of a polytraumatized patient is reported. Emergency thoracotomies are rare interventions in challenging situations. Up to now there are only few standards or uniform education and training concepts. The indications are often a borderline decision. The aim of thoracotomy and open resuscitation in combination with a reduction in circulation, for example by cross-clamping the aorta, is to save time to address reversible causes of the hemorrhage, redirect the blood volume into the vital cerebral and coronary circulation and minimize bleeding from subdiaphragmatic bleeding sources. Ultimately, in case of doubt, the thoracotomy can be performed for the patient's benefit with the appropriate indications.

PURPOSE: Sufficient anchoring of intramedullary osteosynthesis in the femoral head in a femoral neck fracture is a challenge with increasing age of the patients and decreasing bone quality. For older patients with inferior bone quality, it has not been investigated whether the application of an intramedullary force carrier, as a minimally invasive and rapid intervention, can provide a considerable benefit and reduce the postoperative complication and lethality rate. This retrospective study aimed to investigate the stability and functionality after the acute treatment of a femoral neck fracture in osteoporotic bone using an intramedullary force carrier even with higher grade fracture types. MATERIAL AND METHODS: The retrospective analysis was based on a collective of 82 patients over 60 years of age with a femoral neck fracture treated with a gliding nail in our centre between 1999 and 2006. RESULTS: The average time to follow-up was 69.05 months (median 71.0; minimum 27.0-maximum 108.0). Female patients made up more than two-thirds of the patient collective at 63 of the 82 patients (76.83%). The average age of the patients was 77.76 years (median 78.00; range 60.00-93.00).In 66 patients (80.49%), the implantation showed good results and no complications or further treatments. 24/82 patients of our collective had died in our re-evaluation. In no case, a pseudarthrosis or severe impaction with neck shortening occurred (loss of offset).11/82 patients had femoral head necrosis which led to total hip replacement in 8 cases, a hemiarthroplasty in 2 cases and in 1 case a remaining Girdlestone situation because of a deep infection. Another five patients also had to undergo a total hip replacement because of a central perforation of the blade in one case, breakout of the blade after another fall in another two cases and a lateral dislocation of the blade in two cases. CONCLUSION: The use of an intramedullary force carrier in the osteoporotic bone can mean distinct advantages for the selected patient as a minimally invasive and rapid surgical method compared to extensive surgery, even in the case of severe injuries. However, the advantages and disadvantages for the patient should be considered critically.
RESUMEN
BACKGROUND: For the treatment of femoral neck fracture there are many different implants present on the market. Postoperative complications still exist. PATIENTS AND METHODS: The aim of this retrospective study was to evaluate the Gliding Nail in patients with medial femoral neck fractures and their long-term complications. RESULTS: In a collective of 113 patients we had all together 21 major complications in 2018.12/113 minor complications in 2008 and all together 13/78 in 2018 has been detected. CONCLUSIONS: The Gliding Nail as an intramedullary implant shows a high load-bearing capacity with a high rotational stability and a low cut-out rate.
RESUMEN
BACKGROUND: The optimal timing of surgical therapy for traumatic spinal cord injury (TSCI) remains unclear. The purpose of this study is to evaluate the impact of "ultra-early" (<4 h) versus "early" (4-24 h) time from injury to surgery in terms of the likelihood of neurologic recovery. METHODS: The effect of surgery on neurological recovery was investigated by comparing the assessed initial and final values of the American Spinal Injury Association (ASIA) Impairment Scale (AIS). A post hoc analysis was performed to gain insight into different subgroup regeneration behaviors concerning neurological injury levels. RESULTS: Datasets from 69 cases with traumatic spinal cord injury were analyzed. Overall, 19/46 (41.3%) patients of the "ultra-early" cohort saw neurological recovery compared to 5/23 (21.7%) patients from the "early" cohort (p = 0.112). The subgroup analysis revealed differences based on the neurological level of injury (NLI) of a patient. An optimal cutpoint for patients with a cervical lesion was estimated at 234 min. Regarding the prediction of neurological improvement, sensitivity was 90.9% with a specificity of 68.4%, resulting in an AUC (area under the curve) of 84.2%. In thoracically and lumbar injured cases, the estimate was lower, ranging from 284 (thoracic) to 245 min (lumbar) with an AUC of 51.6% and 54.3%. CONCLUSIONS: Treatment within 24 h after TSCI is associated with neurological recovery. Our hypothesis that intervention within 4 h is related to an improvement in the neurological outcome was not confirmed in our collective. In a clinical context, this suggests that after TSCI there is a time frame to get the right patient to the right hospital according to advanced trauma life support (ATLS) guidelines.
RESUMEN
The aim of this retrospective study was to undertake a comparative evaluation of the Evolve® modular metallic radial head implant prosthesis and the MoPyC® pyrocarbon prosthesis in acute care. Seventyfive patients having a comminuted radial head fracture with an Evolve® prosthesis (=G1) and 11 with a MoPyC® prosthesis (=G2) were available for a follow-up. Postoperative patient outcomes were evaluated according to a standardized follow-up protocol which included the Morrey rating system. Assessment criteria were range of motion (ROM), functional scores, and rate of complications. G1 showed a mean Morrey score of 86 points. Four direct prosthesis complications were observed in this group (n=75). The average achieved Morrey score in G2 was 84 points. In this group (n=11), 2 direct prosthesis complications were diagnosed. The average range of motion did not differ greatly between both groups. Radial head replacement with either prosthesis yielded sufficient to satisfactory results in a mid-term perspective regarding the range of motion and function of the elbow joint when performed in carefully selected patients. The Evolve® Prothesis appears to show a slightly lower rate of complication by way of a similar functional outcome.
RESUMEN
INTRODUCTION: Non-union of a long bone fracture remains a challenge in orthopaedic and trauma surgery. In the current study, we sought to determine the clinical effectiveness of tibial non-union treatment utilizing an antibiotic-coated intramedullary nail (Expert Tibia Nail (ETN) PROtect®) regarding prevention and treatment of infection and the clinical outcome. PATIENTS AND METHODS: 36 patients suffering from tibial non-unions that were treated with the ETN PROtect® in the course of non-union treatment between February 2010 and March 2015 were included in this clinical observational study. Clinical and radiological examinations were performed preoperatively as well as 4, 6 and 12 weeks and 6 and 12 months postoperatively as part of a standardized follow-up program. Data regarding perioperative complications, weight-bearing capacity, radiological signs of consolidation and subjective health status were assessed at each time point. Laboratory parameters such as C-reactive protein (CRP) and leukocyte count were collected preoperatively in order to assess the patients' risk profile for infection. RESULTS: Patients had an average of 6.2 previous surgeries and 22 patients (61.1%) had a positive bacterial culture from intraoperatively removed tissue during the first operative treatment. 29 patients (80.6%) achieved full weight-bearing after an average of 7.7 months, furthermore 80.6% of patients achieved osseous consolidation. 3 deep infections occurred, including one amputation. Subjective health status increase based on the SF-12 questionnaire during our follow-up program. CONCLUSION: The results from the current study indicate that the use of the ETN PROtect® in the applied non-union therapy has a high clinical effectiveness regarding osseous consolidation and time to weight bearing. In addition, the use of gentamicin-coated nails in the treatment of tibial non-unions might contribute to both successful treatment of the underlying infection and prevention of perioperative infection. The gentamicin-coated nail may serve as a beneficial adjunct treatment in the applied non-union therapy in addition to all established techniques in the treatment of infected non-unions.

BACKGROUND: Fractures of the proximal femur is one of the most frequent human injuries, and most of the patients are treated with osteosynthesis, such as intramedullary nails. These patients often require magnetic resonance imaging (MRI) scans in their further lives due to various reasons. This raises the question of whether complications with implanted osteosynthesis material such as implant loosening, burning, dislocation, or other complications are to be expected or whether an MRI examination is even suitable with regard to imaging artifacts. METHODS: The aim of this retrospective study was to investigate the rate and type of complications after MRI examinations in patients with inserted intramedullary osteosynthesis device. Furthermore, artifacts in MRI caused by this device were assessed. RESULTS: MRI scans of the head (20 of 62), spine (20 of 62), pelvis (10 of 62), and lower extremity (6/62) were performed. Three of the 62 patients received an MRI of the abdomen, and 2 of the 62 patients received an MRI of the thorax and the upper extremity. Of the 62 patients, noneexperienced complications during the immediate examination. Similarly, none of the patients showed early complications within the first 2 weeks after MRI. In our long-term follow-up examination, no long-term complication after MRI was observed in the recorded 15 patients. Artifacts were found in 14 patients: in MRI scans of the pelvis (10/10), of the abdomen (2/3), and of the lower extremity (2/6). CONCLUSION: There were no complications during the MRI scan, in the first 2 weeks after MRI, or in the recorded long-term results. MRI with an enclosed intramedullary nail provided good image quality unless the immediate implant site was imaged. MRI diagnosis is thus possible in patients with an inserted intramedullary nail. The inserted intramedullary nail should therefore not be an exclusion criterion when sectional imaging with MRI is required.

BACKGROUND: Comminuted radial head fractures are often associated with secondary injuries and elbow instability. OBJECTIVES: The aim of this retrospective study was to evaluate how well the modular metallic radial head implant EVOLVE® prosthesis restores functional range of motion (ROM) and stability of the elbow in acute care. PATIENTS AND METHODS: Eighty-five patients with comminuted radial head fractures and associated injuries received treatment with an EVOLVE® prosthesis between May 2001 and November 2009. Seventy-five patients were available for follow-up. On average, patients were followed for 41.5 months (33.0: 4.0 - 93.0). Outcome assessment was done on the basis of pain, ROM, strength, radiographic findings, and functional rating scores such as Broberg and Morrey, the Mayo elbow performance index (MEPI), and disabilities of the arm, shoulder and hand (DASH). Our study is currently the largest analysis of clinical outcome of a modular radial head replacement in the literature. RESULTS: Overall, there were 2 (2.7%) Mason II fractures, 21 (28%) Mason III fractures, and 52 (69.3%) Mason IV fractures. Arbeitsgemeinschaft fur osteosynthesefragen (AO) classification was also determined. Of the 85 patients in our study, 75 were available for follow-up. Follow-up averaged 41.5 months (range, 4 - 93 months). Average scores for the cohort were as follows: Morrey, 85.7 (median 90.2; range 44.4 - 100); MEPI, 83.3 (85.0; 40.0 - 100); and DASH 26.1 points (22.5; 0.0 - 75.8). Mean flexion/extension in the affected joint was 125.7°/16.5°/0° in comparison to the noninjured side 138.5°/0°/1.2°. Mean pronation/supination was 70.5°/0°/67.1° in comparison to the noninjured side 83.6°/0°/84.3°. Handgrip strength of the injured compared to the non-injured arm was 78.8%. The following complications were also documented: 58 patients had periprosthetic radioluceny shown to be neither clinically significant nor relevant according to evaluated scores; 26 patients had moderate or severe periarticular ossification, and scored substantially worse according to MEPI and Morrey. Four patients required revisional surgery due to loosening of the prosthesis and chronic pain. In addition, one patient required a neurolysis of the ulnaris nerve, one developed a neobursa, and one had extensive swelling and blistering. The time interval between injury and treatment appeared to have an effect on results. Thirty-five patients were treated within the first 5 days after accident and showed better results than the 40 patients who were treated after 5 days. CONCLUSIONS: Comminuted radial head fractures with elbow instability can be treated well with a modular radial head prosthesis, which restores stability in acute treatment. The modular radial head arthroplasty used in this study showed promising findings in short to midterm results.
