Consensus for management of sacral fractures: from the diagnosis to the treatment, with a focus on the role of decompression in sacral fractures.

BACKGROUND: There is no evidence in the current literature about the best treatment option in sacral fracture with or without neurological impairment. MATERIALS AND METHODS: The Italian Pelvic Trauma Association (A.I.P.) decided to organize a consensus to define the best treatment for traumatic and insufficiency fractures according to neurological impairment. RESULTS: Consensus has been reached for the following statements: When complete neurological examination cannot be performed, pelvic X-rays, CT scan, hip and pelvis MRI, lumbosacral MRI, and lower extremities evoked potentials are useful. Lower extremities EMG should not be used in an acute setting; a patient with cauda equina syndrome associated with a sacral fracture represents an absolute indication for sacral reduction and the correct timing for reduction is "as early as possible". An isolated and incomplete radicular neurological deficit of the lower limbs does not represent an indication for laminectomy after reduction in the case of a displaced sacral fracture in a high-energy trauma, while a worsening and progressive radicular neurological deficit represents an indication. In the case of a displaced sacral fracture and neurological deficit with imaging showing no evidence of nerve root compression, a laminectomy after reduction is not indicated. In a patient who was not initially investigated from a neurological point of view, if a clinical investigation conducted after 72 h identifies a neurological deficit in the presence of a displaced sacral fracture with nerve compression on MRI, a laminectomy after reduction may be indicated. In the case of an indication to perform a sacral decompression, a first attempt with closed reduction through external manoeuvres is not mandatory. Transcondylar traction does not represent a valid method for performing a closed decompression. Following a sacral decompression, a sacral fixation (e.g. sacroiliac screw, triangular osteosynthesis, lumbopelvic fixation) should be performed. An isolated and complete radicular neurological deficit of the lower limbs represents an indication for laminectomy after reduction in the case of a displaced sacral fracture in a low-energy trauma associated with imaging suggestive of root compression. An isolated and incomplete radicular neurological deficit of the lower limbs does not represent an absolute indication. A worsening and progressive radicular neurological deficit of the lower limbs represents an indication for laminectomy after reduction in the case of a displaced sacral fracture in a low-energy trauma associated with imaging suggestive of root compression. In the case of a displaced sacral fracture and neurological deficit in a low-energy trauma, sacral decompression followed by surgical fixation is indicated. CONCLUSIONS: This consensus collects expert opinion about this topic and may guide the surgeon in choosing the best treatment for these patients. LEVEL OF EVIDENCE: IV.

Development of the Italian fractures registry (RIFra): A call for action to improve quality and safety.

In recent years, there has been an increasing interest in the development of arthroplasty registries, therefore, in our country, the Italian Arthroplasty Registry (RIAP), was issued by the National Law No. 221/2012. In the last decade, however, some European countries -namely Sweden, Denmark, Norway, and Germany (in development)- have introduced another nationwide orthopaedic registry than arthroplasty registers: the fracture registry. The development of this new tool aims to improve quality and safety in fracture management, thus trying to provide a better postoperative quality of life in trauma patients. Based on these findings, the AO-Trauma Italy Council encouraged the development of a national fracture registry in Italy. The present study aims to (1) provide an overview of the fracture registries in Europe and (2) to develop, for the first time, a pilot Italian Fracture Registry (RIFra). Thirteen AO-Trauma Italy members, chairmen of Level-I orthopaedic and trauma centres, diffused throughout Italy, were involved in the RIFra project. The RIFra form, developed between November 2019 and March 2020, consists of 5 main sections, namely: epidemiologic data, previous surgical procedure (if any), patient and fracture features, surgical procedure, surgical implant details. This study constitutes the first step to start, in future years, the bureaucratic procedure leading to the final establishment of a RIAP-like fracture registry in Italy.

Alternative Use of the Ilizarov Apparatus Set in Case of Complications During Intramedullary Nail Removal: A Case Report.

CASE: We present 2 case reports: the first, a diaphyseal fracture of the humerus treated with a Marchetti nail resulting in a nonunion in 2017. The second, a fracture of the femur treated with a Kuntscher nail in 1989. A gunshot injury to that femur in 2014 evolved in nonunion and displacement. In both cases, the old nails were removed by using pieces of the Ilizarov apparatus. CONCLUSIONS: In case of complications, the versatility of the Ilizarov apparatus allows us to connect the intramedullary element to the universal extraction system; it proves itself to be an excellent cost-effective extraction system.

Cementless Hemiarthroplasty for Intracapsular Femoral Neck Fractures in the Octa- and Nonagenarians.

BACKGROUD: Current evidence supports the use of cemented hemiarthroplasty for treatment of intracapsular femoral neck fractures since it is associated with a lower risk of implant-related complications. However, many medical centers employ the cementless technique for the frail elderly population because it is faster and has lower cardiovascular risks and perioperative mortality. This observational study reports the outcomes of cementless bipolar hemiarthroplasty for intracapsular femoral neck fractures in patients aged 80 years and older. METHODS: A total of 424 patients (female, 77.1%) with a mean age of 86.9 years were operated for intracapsular femoral neck fractures between January 2009 and December 2017. Of those, 66.7% had an American Society of Anaesthesiologists (ASA) score of 3 or more. All operations were performed with the posterolateral surgical approach and all patients received a cementless stem. Intraoperative and perioperative values and in-hospital outcomes were evaluated, and clinical and radiographical follow-up was done at 40 days, 90 days, and when possible between 5 months and 12 months postoperatively. Multivariate analysis was performed to evaluate if there were factors affecting mortality. RESULTS: The mean operative time was 50 minutes. There were no deaths intraoperatively. Intraoperative periprosthetic fractures occurred in 2.1% of the cases with 66.7% of them fixed through cerclage wires intraoperatively. The median length of hospitalization was 11 days (interquartile range, 8.75-15) and 2.4% of patients died while in hospital after surgery. Approximately 91.5% of patients presented with perioperative anemia. Only 1.9% of the complications were related to the implant, 62.5% of which were dislocations. More than 90% of patients were ambulatory either autonomously or with support at each follow-up assessment. Age, male sex, and higher ASA score were related to increased mortality. CONCLUSIONS: Despite some limitations, this observational study underlines that a cementless femoral stem of modern design can give good clinical outcomes, thus being an appropriate solution especially for the frail elderly.

Orthopedic injuries in patients with multiple injuries: Results of the 11th trauma update international consensus conference Milan, December 11, 2017.

BACKGROUND: In blunt trauma, orthopedic injuries are often associated with cerebral and torso injuries. The optimal timing for definitive care is a concern. The aim of the study was to develop evidence-based guidelines for damage-control orthopedic (DCO) and early total care (ETC) of pelvic and long-bone fractures, closed or open, and mangled extremities in adult trauma patients with and without associated injuries. METHODS: The literature since 2000 to 2016 was systematically screened according to Preferred Reporting Items for Systematic Reviews and meta-analyses protocol. One hundred twenty-four articles were reviewed by a panel of experts to assign grade of recommendation and level of evidence using the Grading of recommendations Assessment, Development, and Evaluation system, and an International Consensus Conference, endorsed by several scientific societies was held. RESULTS: The choice between DCO and ETC depends on the patient's physiology, as well as associated injuries. In hemodynamically unstable pelvic fracture patient, extraperitoneal pelvic packing, angioembolization, external fixation, C-clamp, and resuscitative endovascular balloon occlusion of the aorta are not mutually exclusive. Definitive reconstruction should be deferred until recovery of physiological stability. In long bone fractures, DCO is performed by external fixation, while ETC should be preferred in fully resuscitated patients because of better outcomes. In open fractures early debridement within 24 hours should be recommended and early closure of most grade I, II, IIIa performed. In mangled extremities, limb salvage should be considered for non-life-threatening injuries, mostly of upper limb. CONCLUSION: Orthopedic priorities may be: to save a life: control hemorrhage by stabilizing the pelvis and femur fractures; to save a limb: treat soft tissue and vascular injuries associated with fractures, stabilize fractures, recognize, and prevent compartmental syndrome; to save functionality: treat dislocations, articular fractures, distal fractures. While DCO is the best initial treatment to reduce surgical load, ETC should be applied in stable or stabilized patients to accelerate the recovery of normal functions. LEVEL OF EVIDENCE: Systematic review of predominantly level II studies, level II.

[18F]FDG PET/CT in non-union: improving the diagnostic performances by using both PET and CT criteria.

PURPOSE: Complete fracture healing is crucial for positive patient outcome. A major complication in fracture treatment is non-union. Infection is among the main causes of non-union and hence of osteosynthesis failure. For the treatment of non-union, it is crucial to understand whether a fracture is not healing because of an underlying septic process, since the surgical approach to non-unions definitely differs according to whether the fracture is infected or aseptic. We aimed to assess the diagnostic performance of 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography-computed tomography ([18F]FDG PET/CT) in the evaluation of infection as possible cause of non-union. METHODS: We retrospectively evaluated images of 47 patients treated in our trauma center who, between January 2011 and June 2017, underwent preoperative [18F]FDG PET/CT aiming to exclude infection in non-union. Clinical data, diagnostic examinations, laboratory and microbiology results, and patient outcome were collected and analyzed. [18F]FDG PET/CT images were visually and semiquantitatively evaluated using the maximum standardized uptake value (SUVmax). Imaging findings, as assessed by an experienced nuclear medicine physician and an experienced musculoskeletal radiologist, were compared with intraoperative microbiological culture results, which were used for final diagnosis (reference standard). The diagnostic performance of [18F]FDG PET/CT in detecting infected non-union was assessed. RESULTS: Twenty-two patients were not infected, while the remaining 25 had positive intraoperative microbiological results. C-reactive protein (CRP) was within the normal range in 13 cases (five with a final diagnosis of infection) and higher than normal in 25 patients (13 with a final diagnosis of infection). Infection was correctly detected on visual analysis of PET/CT images in 23 cases, while 2/25 infected patients had no significant [18F]FDG uptake and were considered false negatives. In seven cases, [18F]FDG PET/CT showed false positive results; 15/22 disease-free patients were correctly diagnosed. The diagnostic accuracy of [18F]FDG PET/CT in the final diagnosis of infection was 81% (38/47); its sensitivity, specificity, positive predictive value, and negative predictive value were 92%, 68%, 77%, and 88% respectively. The likelihood ratio for a positive test (LR+) was 2.89 and for a negative test, 0.12. Pretest probability of disease was 53%. Post-test probability based on LR+ was 77%. CONCLUSION: [18F]FDG PET/CT is a promising tool for diagnoses of infected non-unions. Both PET and CT images should be interpreted to achieve a high sensitivity (92%) and a very good negative post-test probability (12%).

Reverse total shoulder versus angular stable plate treatment for proximal humeral fractures in over 65 years old patients.

BACKGROUND: Treatment for displaced proximal humeral fractures is still under debate. Poor rotator cuff status and non-union of the tubercles in elderly patients has caused reversed total shoulder prosthesis growing popularity and showed promising results, even in comparison to angular stable plates fixation.The purpose of this study is to report clinical and radiological results of proximal humerus fractures treated with rTSA or ORIF in elderly. MATERIALS AND METHODS: The study has investigated retrospectively a consecutive series of 73 patients over 65 years old (range 65-91) with proximal humeral three- and four- parts fractures, operated from January 2009 to June 2014 with a reversed total shoulder prosthetic replacement or open reduction and internal fixation using an angular stable plate, with at least 1 year follow-up. Participants are admitted in our hospital with a displaced proximal humeral fracture according to AO-OTA type 11-B2 or 11-C2.The primary outcomes are active ROM and shoulder function (Constant score). Secondary outcomes have been patient self-assessment form (Simple shoulder test) and radiographical details. Follow-up takes place at the moment of clinical observation with rx control. RESULTS: We analyzed a group of 23 patients treated by plate and screws and 21 patients treated by rTSA with these average results. ORIF: Flexion 112.8°, Abduction 99.6°, External rotation at 90° 47.4°, modal Internal rotation hand at Sacroiliac joint, Constant Score 52.9 and Simple Shoulder Test 8.0. RSA: Flexion 133.3°, Abduction 101.4°, External rotation at 90° of abduction 35.5°, modal Internal rotation hand at waist (L3), Constant Score 65.9 and Simple Shoulder Test 9.2. No nerve injuries were reported. No cases of pseudoarthrosis or plate fractures. No arthroplasty implant loosening, infection or dislocation was documented and revision required. CONCLUSION: Our study shows good clinical outcomes and fewer complications in both treatment options. Better clinical and daily living results are reported in RSA compared with ORIF, confirming that rTSA is one of the best treatment in proximal humeral fractures in the elderly patients, which rotator cuff status frequently is poor and degenerating. The few radiological complications do not seem to have influence on active ROM and Constant Score, both the first and the second group of patients. LEVEL OF EVIDENCE: Level IV, Case Series, Surgical.

Posterior sternoclavicular joint dislocation with brachiocephalic vein injury: a case report.

Posterior dislocation of the clavicle is an uncommon injury, usually related to road traffic or contact sports accidents. The close proximity of vital structures in the mediastinum should alert the surgeon avoiding a closed reduction in the emergency setting. A multidisciplinary team of expert surgeons should be involved and a combined procedure performed. Nevertheless, the risk of developing complications is high. We report this case in order to outline one of the potential complications, to discuss appropriate imaging studies and to describe the details of a safe surgical approach.

High incidence of hypocalcemia and serum creatinine increase in patients with bone metastases treated with zoledronic acid.

BACKGROUND: Zoledronic acid belongs to the new generation of bisphosphonates with demonstrated clinical benefit for the treatment of bone metastases from different kinds of neoplasms. Hypocalcemia and serum creatinine elevation are expected adverse events during this therapy. The monitoring of serum calcium and creatinine is therefore recommended. The primary aim of this study was to establish the actual incidence of hypocalcemia and serum creatinine elevation during treatment with zoledronic acid. Skeletal-related events and side effects were also assessed. METHODS: Serum creatinine and calcium levels were evaluated in 240 consecutive patients (83 males, 157 females; mean age, 62 years) with metastatic bone lesions from different solid tumors treated with zoledronic acid. RESULTS: Overall, 93 of 240 patients (38.8%) developed hypocalcemia, which was grade (G)1 in 45 patients (48.4%), G2 in 37 patients (39.8%), G3 in 10 patients (10.8%), and G4 in one patient (1.1%). The median time to occurrence of hypocalcemia (any grade) was 2.3 months after the beginning of the treatment (range, 0-34.9 months). Increased serum creatinine was observed in 33 of 240 patients (13.7%), of whom 19 had G1 (57.6%), 11 had G2 (33.3%), and three had G3 (9.1%). The median time to serum creatinine increase (for any grade) was 4.7 months (range, 0-29.2 months). CONCLUSIONS: Our analysis shows a high incidence of hypocalcemia and increased serum creatinine level during treatment with zoledronic acid. These results strongly support the need for accurate monitoring of plasma calcium and creatinine levels.
