Rehabilitative management of pelvic fractures: a literature-based update.

A comprehensive rehabilitation program is required after Pelvic Fracture (PF). In a PF rehabilitation setting an effective treatment and a proper management of complications is supplied by an appropriate and reliable clinical assessment. In this literature-based update, we search on MEDLINE, EMBASE, and the Cochrane Database of Systematic reviews to find articles, scientific society guidelines and practioners experiences defining the rehabilitative management of clinically PF outcomes. Based on literature evidences and expert opinions, a set of key topics was collated to generate advices and recommendations to put into daily practice. Even if there are no high-quality evidence for rehabilitative interventions after PF in terms of duration and modality of therapy, rehabilitation setting, care pathways, and long-term functional outcomes, it is strongly recommended an early multidisciplinary intervention to improve recovery from PF.

Italian Consensus Conference on Guidelines for preoperative treatment in acetabular fractures.

Preoperative management of acetabular fracture is a major problem and no consensus has been reached in literature on the optimal treatment of this problem. We present the results of the First Italian Consensus Conference on Acetabular fracture. An extensive review of the literature has been undertaken by the organizing committee and forwarded to the panel. Members were appointed by surgical experience with acetabular fractures. From November 2017 to January 2018, the organizing committee undertook the critical revision and prepared the presentation to the Panel on the day of the Conference. Then 11 recommendations were presented according to the 11 submitted questions. The Panel voted the recommendations after discussion and amendments with the audience. Later on, a second debate took place in September 2018 to reach a unanimous consent. We present results of the following questions: does hip dislocation require reduction? Should hip reduction be performed as soon as possible? In case of unsuccessful reduction of the dislocation after attempts in the emergency department, how should it be treated? If there is any tendency toward renewed dislocation, how should it be treated? Should Computed Tomography (CT) scan be performed before reduction? Should traction be used? How can we treat the pain? Is preoperative ultrasound exam to rule out vein thrombosis always necessary? Is tranexamic acid intravenous (IV) preoperatively recommended? Which antibiotic prophylactic protocols should be used? Is any preoperative heterotopic ossification prophylaxis suggested? In this article we present the indications of the First Italian Consensus Conference: a hip dislocation should be reduced as soon as possible. If unsuccessful, surgeon may repeat the attempts optimizing the technique. Preoperative CT scan is not mandatory before reduction. Skeletal traction is not indicated in most of the acetabular fracture. Standard pain and antibiotic prophylactic protocols for trauma patient should be used. Preoperative ultrasound exam is not recommended in all acetabular fracture. Tranexamic acid should be preoperatively used. There is no indication for preoperative heterotopic ossification.

Radiographic and functional outcome of complex acetabular fractures: implications of open reduction in spinopelvic balance, gait and quality of life.

Aim To investigate the effects of surgical reduction of complex acetabular fractures on spine balance, postural stability and quality of life. Methods Twenty-six patients with acetabular fractures surgically treated by open reduction and internal fixation were divided into two groups according to the amount of reduction. Group A consisted of 18 patients with satisfactory reduction (≤2 mm), and group B of eight patients with incomplete reduction (>2 mm). Functional outcome was measured with Harris Hip Score (HHS), Oswestry Disability Index (ODI), and Short Form (12) Health Survey (SF12). Radiological parameters were assessed with standing whole spine, pelvis and hip X-rays, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and sagittal vertical axis (SVA). Follow-up intervals were 1, 3, 6 and 12 months and annually thereafter. Gait analysis and baropodometry were performed after 24 months of operation. Results Mean HHS, ODI, and SF-12 was improved during the first postoperative year in both groups. After two years average scores kept improving for group A, but worsened for group B. Mean PI, PT, and SS increased in both groups during the first postoperative year, with further increase after two years only in group B. After two years, 16 (89%) patients in group A and four (50%) in group B had a balanced spine (SVA <50 mm). Gait analysis and baropodometry showed greater imbalance and overload for group B compared to group A. Conclusion In the long term, incomplete reduction of associated acetabular fractures may lead to poor outcome because of secondary spinopelvic imbalance, with posture and gait impairment.

A new prognostic pelvic injury outcome score.

Aim To propose a new prognostic classification system for pelvic injuries based on a new detailed and all-encompassing evaluation of the injury pelvic outcome score and to check the prognostic value of this classification and evaluate its reliability and reproducibility. Methods From January 2017 to June 2020 from 156 pelvic fractures treated at our hospitals, 98 patients with pelvic fractures were recruited according to inclusion and exclusion criteria. All patients compiled three scores (New Score System, Majeed Score, SF-12) sessions two times during the hospital stay to evaluate the endpoint before the trauma and two years after the trauma. All patients carried out three tests independently. The evaluation of three scores included a pelvic and general complication after the surgery, the times needed to compile three score system. For reliability of the new score systems we evaluated the inter-observer or intraobserver agreement, the prediction strength of each score, and a prognostic value. Results A total of 98 patients were enrolled (74 were males and 24 females) with mean age of 43.6 (±18.6) (range 16-75) years. Tau B Kendall value was 0.827 for the new score system, 0.673 for the Majeed score, 0.746 for SF-12, there was p<0.05 for the new score system. Conclusion The new score system is prognostic, reliable, reproducible and can become a useful instrument to adequately correlate the long-term outcomes of pelvic injury fractures. Also, it provides a better evaluation of pain, work, sexual possibilities and satisfaction, balance-sitting-walking and psychological status.

Triradiate cartilage fracture of the acetabulum treated surgically.

Fractures of the acetabulum are rare in the pediatric age and may be complicated by the premature closure of the triradiate cartilage. We report a case of triradiate cartilage displaced fracture treated surgically. A 14 years old boy, following a high-energy road trauma, presented an hematoma in the right gluteal region with severe pain. According to radiographic Judet's projections was highlighted a diastasis of the right acetabular triradiate cartilage.  CT scan study with 2D-3D reconstructions confirmed as type 1 Salter-Harris epiphyseal fracture. Due to the huge diastasis of the triradiate cartilage, the patient was operated after 72 hours through a plating osteosynthesis. We decided during the preoperative study that the plates should not be removed. Two years after surgery, the patient is clinically asymptomatic; the radiographic evaluation shows a complete cartilage's fusion and the right acetabulum is perfectly symmetrical to the contralateral. For the treatment of acetabular fractures in pediatric age should be carefully evaluated fracture's pattern, patient's age, skeletal maturity's grade, acetabulum's volume and diameter.

Challenges in the management of floating knee injuries: Results of treatment and outcomes of 224 consecutive cases in 10 years.

INTRODUCTION: Floating knee is a flail knee joint resulting from fractures of the shafts or adjacent metaphyses of the femur and the ipsilateral tibia. It is usually associated with several complications and mortality. This study was designed to present our experience with the treatment of this injury. MATERIAL AND METHOD: This study was performed between January 2004 and December 2014. 224 cases of floating knee injuries gathered from the 34,480 lower extremities trauma files were studied, and the target information recorded. The injuries most frequently occurred in subjects between 16 and 35 years of age (60.71%), and in male subjects (85.71%). The most frequent mechanism of injury was traffic accident (92.85%). External fixation was the common type of treatment (82.14%) in emergency or as a definitive treatment. The treatment was performed within 24 h of the trauma. We performed a 36-month follow up with clinical examination, radiographs, assessing the complications, and using the Modified Cincinnati Rating System Questionnaire (MCRSQ) and the Karlström/Olerud Score (KOS) to evaluate the progression of the outcomes. RESULTS: Early complications included 8 cases of compartment syndrome, 60 open fractures and 24 partially amputated limbs. A total amputation was performed in 3 patients. The most common late complication was heterotopic calcifications of the knee (n = 68, 30.6%). Good scores for MCRSQ and KOS were obtained only after patients were sent to a reference center for knee surgery. CONCLUSIONS: Our experience revealed that the complication rate associated with floatingknee injuries remains high, regardless of the performed treatment. Surgeons should focus on reducing complications while treating these severe injuries.

Correction of multiple complex lower limb deformities by intramedullary nailing.

A female patient presented to our institution suffering from long bone post-traumatic multiple deformities. Her walking was limited, painful and teetering. It had worsened over the past months. The right leg was shortened by 6 cm compared to the contralateral. The right femur was 18° varus, the right tibia was 16° valgus, the left tibia was 12° varus. Both knee joints showed marked radiographic signs of osteosclerosis. After a thorough study with simulations using paper models, we carried out three osteotomies, two open wedge and one cuneiform, stabilizing them with intramedullary nails. We conducted the operation in two stages, in order to avoid an excessive surgical stress that could give rise to complications such as DVT, fat embolism, and respiratory insufficiency. This allowed a rapid recovery of her weight bearing and walking capacity, reducing significantly also the leg length discrepancy. She progressed uneventfully to healing of the osteotomy sites and she returned to her previous occupation.

Causes of failure in periprosthetic fractures of the hip at 1- to 14-year follow-up.

INTRODUCTION: The results and causes of failure for 61 patients undergoing surgery for femoral hip periprosthetic fracture are reported. MATERIALS AND METHODS: Fractures were classified according to the Vancouver System. Osteosynthesis was performed in 88% of cases and prosthetic revision in 12% of cases. Clinical and functional outcomes were assessed according to the Harris Hip Score and radiological results were evaluated using Beals and Tower's criteria. RESULTS: At a mean follow-up of 32 months, the Harris Hip Score was 73.1 and the radiological results were excellent-to-good in 72.2% of patients after the first surgery. At the end of treatment, complete healing of the fracture and stability of the prosthesis was found in 87.3% of patients. The most relevant result was the recovery of walking in 73.8% of patients. Mortality after surgery was 1.6% at 3 months and 3.3% at 12 months. A higher mortality rate occurred when surgery was delayed more than 5 days after trauma. CONCLUSIONS: The analysis of our cases shows that in Vancouver type B1 fractures treated with plating osteosynthesis, there were worse outcomes in total hip arthroplasty with cemented stems compared with uncemented stems. In Vancouver type B2 fractures with cementless straight stems, osteosynthesis with a plate can be a valid option. In Vancouver type C fractures, the stability of the stem must be carefully assessed.
