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. TRIAL REGISTRATION: not applicable (consensus paper).

Isolated greater trochanter fractures.

INTRODUCTION: Isolated fractures of the greater trochanter (GT) in adults are rare injuries and traditionally treated without surgery. The present systematic review was designed to examine the treatment protocol for isolated GT fractures and to discover if innovative surgical techniques, such as arthroscopy or suture anchors, can be used to improve outcomes in young active patients. METHODS: A systematic review was conducted including all full-text articles suited our inclusion criteria from January 2000 describing treatment protocols of isolated great trochanter fractures confirmed at MRI in adults. RESULTS: The searches identified a total of 247 patients from 20 studies with a mean age 56.1 years and mean follow-up 13,7 months. Only 4 case report treated 4 patients with not unique surgical strategy. The rest of the patients were treated conservatively. DISCUSSION: Most trochanteric fractures can heal without surgical intervention with good results However, the patient must not immediately bear full weight and the abductor's function could decrease. Displaced GT fragments more than 2 cm or athletes, young, demanding patients may benefit from surgical fixation to regain abductor function and strength. Evidence-based surgical strategies could be provided by arthroplasty and periprosthetic literature. CONCLUSION: The grade of fracture displacement and the physical demands of the athlete can be important factors in the decision process for or against surgery. By now, no evidence-based guideline exists for the ideal treatment method in demanding patients. It is necessary use a "patient-specific" treatment strategy.

Suprapatellar nail removal after suprapatellar nailing of the tibia: it could work!

BACKGROUND AND AIM OF THE WORK: Intramedullary nailing is a fundamental tool for the treatment of meta-diaphyseal tibia fractures. While, in the past, the infrapatellar approach was the only one available, over the last few years, an alternative approach has been developed: the suprapatellar tibial nailing. This technique has shown some advantages over the other one. However, as the most recent method has become increasingly more common, concerns have been put forward about the possibility to remove the nail using only the infrapatellar approach, thus incising the previously unviolated patellar tendon. The aim of our study is to describe the technique and the results of a suprapatellar approach to remove the nail. METHODS: We describe the surgical technique used to remove the tibial nail via the suprapatellar approach. We analyze a small case series of 12 patients who underwent the operation of nail removal, analyzing operation time, intraoperative and/or postoperative complications and clinical outcomes. RESULTS: The mean duration of the operation was 39.8 minutes. The difference between the two values of the Lysholm score (pre- and postoperative) in each patient was not statistically significant, ranging between -2 to +4 points. We did not observe any intraoperative or postoperative complications. CONCLUSIONS: After suprapatellar nailing of the tibia, it is possible to remove the nail using the same suprapatellar approach with a safe, easy and reproducible technique. The clinical results observed in our case series show excellent outcomes in terms of absence of complications and good functional knee score.

Is non-operative management of acetabular fracture a viable option for older patients? A systematic review of the literature for indication, treatments, complications and outcome.

There is no consensus about the best treatment for acetabular fracture in older patients. The purpose of this study was to review the current literature looking for indication, perioperative information and outcome of nonoperative management for acetabular fractures in elderly.A systematic review of literature was performed on different research database by using various combination of the keywords "acetabular fracture", "elderly patients", "60 years", "nonoperative", "nonsurgical" and "conservative treatment".Six articles met our inclusion criteria, 315 patients aged 60 or more treated nonoperatively for acetabular fracture were included in the analysis. The average age was 78.1 years, the average follow-up length was 48.7 months. The main criteria for indication of nonoperative management for acetabular fractures were, old age (75 years or more), two or more important medical comorbidities, and minimally or undisplaced fracture. The most frequent fracture pattern was anterior column in 25.3% of cases. Fall from standard height was the most frequent causative mechanism in 80% of patients. A conversion total hip arthroplasty was performed after 8.3% of cases. A 1-year mortality of 18% was reported, an overall mortality of 33.1% at last follow-up was reported.The management of acetabular fractur in elderly is a challenging problem and there is no consensus about the best treatment. Currently, multiple treatment options have been suggested, depending on fracture pattern and patients' general conditions. Although operatively treatment allow for an early recovery, there is not an high level of evidence about the superiority in terms or complications and mortality rate compared to nonoperative treatment.

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.

Intramedullary cortical fragment in tibial nailing: push it, remove it or ignore it?

Intramedullary nailing of long bones is a safe procedure, with excellent long-term results. Even in apparently simple fractures, many complications may arise. Incarceration of a cortical fragment in the medullary canal is a fearsome situation, which may lead to severe complications and, consequently, poor outcomes. The surgeon should be aware of this risk and, after careful analysis of the pre-operative imaging, must remove or, at least, disengage the fragment from the medullary canal.

Timing of surgical intervention for compartment syndrome in different body region: systematic review of the literature.

Compartment syndrome can occur in many body regions and may range from homeostasis asymptomatic alterations to severe, life-threatening conditions. Surgical intervention to decompress affected organs or area of the body is often the only effective treatment, although evidences to assess the best timing of intervention are lacking. Present paper systematically reviewed the literature stratifying timings according to the compartmental syndromes which may beneficiate from immediate, early, delayed, or prophylactic surgical decompression. Timing of decompression have been stratified into four categories: (1) immediate decompression for those compartmental syndromes whose missed therapy would rapidly lead to patient death or extreme disability, (2) early decompression with the time burden of 3-12 h and in any case before clinical signs of irreversible deterioration, (3) delayed decompression identified with decompression performed after 12 h or after signs of clinical deterioration has occurred, and (4) prophylactic decompression in those situations where high incidence of compartment syndrome is expected after a specific causative event.

Long head of biceps in proximal fractures of the humerus: an underestimated problem?

BACKGROUND AND AIM OF THE WORK: The long head of biceps (LHB) is one of the tendons of the rotator cuff that runs strictly close to the humeral head. In case of pathology, it can be responsible for pain and shoulder impairment: in such cases, surgical options include tenotomy or tenodesis. The management of LHB along with surgery of the rotator cuff or during shoulder prosthetic replacement has been widely discussed in the literature. Conversely, the possibility of acute impingement and incarceration of LHB in proximal humerus fractures, as well as its role in shoulder pain in outcomes of these fractures, has been poorly considered. METHODS: The following aspects in the literature on LHB and proximal humerus fractures have been analysed: its management during fixation of fractures, the possibility of interference of the tendon with reduction of fractures or dislocations of the shoulder and its possible role in chronic pain after fixation of proximal humerus fractures. RESULTS: LHB can be an obstacle in the reduction of fractures, dislocations and fracture-dislocations. Only a few papers take into account acute surgery to LHB (tenotomy or tenodesis); most of the studies on fixation of proximal humerus fractures simply ignore the problem of LHB. The tendon can be a source of pain and a cause of disability in sequelae of these fractures. CONCLUSIONS: LHB should be taken into consideration both in the acute phase of fractures of the proximal humerus and in the outcomes. Other studies are needed to better understand its optimal management during fracture surgery.

Rotational malalignment in femoral nailing: prevention, diagnosis and surgical correction.

BACKGROUND AND AIM OF THE WORK: to review and discuss the literature about rotational malalignment during and after femoral nailing. METHODS: analysis of the literature on prevention and evaluation of rotation during femoral nailing, clinical and subjective consequences of malrotation and techniques used to correct the deformity, both in the acute and chronic phase. RESULTS: malrotation is very common after femoral nailing. The exact definition of a malrotated femur is controversial, but it is widely agreed that a rotational malalignment <10° is considered normal while >30° is a deformity which requires correction. The complaints of the patients with a malrotated femur can be various and can involve the hip, the knee or below the knee. The ability to compensate for the deformity while standing and walking may decrease the symptoms. Surgical correction is feasible with many techniques and devices: the procedure involving derotation, changing the locking screws and maintaining the nail is safe, reproducible and relatively easy. CONCLUSIONS: prevention of malrotation during femoral nailing is the cornerstone of successful operation outcomes. If rotational malalignment is suspected, prompt diagnosis and adequate surgical treatment are mandatory to overcome this common complication.

Locked posterior fracture-dislocation of the shoulder.

BACKGROUND AND AIM OF THE WORK: To describe a valid option for the treatment of locked posterior fracture-dislocation of the shoulder (LPFDS) and to compare it to the literature about this topic. METHODS: We present a small case series (3 patients), with a medium follow up at 4 years and 5 months. We accurately describe our surgical strategies, underlining the choice of approach, reduction and fixation. RESULTS: The three patients showed excellent functional and radiological results at the follow up examinations, with a full range of shoulder movements and complete regain of pre-trauma activities. A lateral approach (standard or minimally invasive), a reduction technique with a Shantz pin in the head and in the humeral shaft, and fixation with a locking plate were used in the three patients. CONCLUSION: LPFDS is a challenging lesion, hard to recognize and to treat. Our suggested method of treatment is highly reproducible and has revealed itself to be very effective in achieving good results.

Outcome of cages in revision arthroplasty of the acetabulum: a systematic review.

BACKGROUND AND AIM OF THE WORK: To investigate the clinical, radiological and functional outcomes of acetabular revisions with acetabular reinforcement rings and cages. METHODS: A comprehensive literature study of international databases was performed. Inclusion criteria were cementless revisions, use of reinforcement rings, radiological and clinical follow-up, availability of full text in English, publication between January 1990 and July 2018. In a second further analysis, we selected only studies describing patients with more severe acetabular defects (AAOS 3, AAOS 4, Paprosky III). Data extracted included mean follow-up period, radiographic follow-up, functional scores, implant failures and survival rate. RESULTS: We included in our review 1327 acetabular revisions described in 28 articles. The most commonly used reinforcement rings were Burch-Schneider ring, the Muller ring and the Ganz ring. Mean follow-up for all patients together was 8.8 years. Clinical or radiological signs of loosening were reported in 191 patients, 83 patients needed further acetabular revision for aseptic loosening and 41 patients received additional surgeries for septic loosening. The mean value of the Harris Hip Score reported at the last follow-up was 76.3. Nineteen articles fulfilled the criteria for further analysis about high-grade acetabular bone defects. We analyzed 649 revisions with mean follow-up period of 8.2 years. Clinical or radiological loosening was reported in 90 patients, additional acetabular revision was performed in 39 patients and 25 patients needed further surgeries for deep infection. CONCLUSION: Acetabular revisions with cages are characterized by good survival rates and functional scores with a mean follow-up period of 8 years.

Can Clinical and Surgical Parameters Be Combined to Predict How Long It Will Take a Tibia Fracture to Heal? A Prospective Multicentre Observational Study: The FRACTING Study.

BACKGROUND: Healing of tibia fractures occurs over a wide time range of months, with a number of risk factors contributing to prolonged healing. In this prospective, multicentre, observational study, we investigated the capability of FRACTING (tibia FRACTure prediction healING days) score, calculated soon after tibia fracture treatment, to predict healing time. METHODS: The study included 363 patients. Information on patient health, fracture morphology, and surgical treatment adopted were combined to calculate the FRACTING score. Fractures were considered healed when the patient was able to fully weight-bear without pain. RESULTS: 319 fractures (88%) healed within 12 months from treatment. Forty-four fractures healed after 12 months or underwent a second surgery. FRACTING score positively correlated with days to healing: r = 0.63 (p < 0.0001). Average score value was 7.3 ± 2.5; ROC analysis showed strong reliability of the score in separating patients healing before versus after 6 months: AUC = 0.823. CONCLUSIONS: This study shows that the FRACTING score can be employed both to predict months needed for fracture healing and to identify immediately after treatment patients at risk of prolonged healing. In patients with high score values, new pharmacological and nonpharmacological treatments to enhance osteogenesis could be tested selectively, which may finally result in reduced disability time and health cost savings.

Scapulothoracic dissociation: a devastating "floating shoulder" injury.

Background and aim of the work The term "floating shoulder" was used in a previous paper to describe lesions of at least two components of the SSSC (superior shoulder suspensory complex), a bony-ligamentous structure of the shoulder girdle. Following this article other types of floating shoulder were described, including scapulothoracic dissociation (STD), a rare lesion with potentially devastating consequences, with detachment of the scapular body from the thoracic wall, with following lateralization of the scapula,  fracture of the clavicle or injury of the adiacent sterno-clavear or acromion-clavicular joints. Prognosis and outcome are also negatively influenced by secondary vascular and neurologic injuries.  Methods We review the literature on this lesion and we describe two patients with STD, their treatment and outcome.  Results Reviewing the literature and analysing our cases, we point out that the STD is often associated with serious general lesions and is indicative of an high-energy trauma. The consequences can be disabling for the upper limb (20% amputation, 50% flail limb) or for the general status of the patient (10% mortality).  Conclusions STD must be timely recognized and subsequently properly treated, to avoid the associated general and local injuries (vascular) and subsequently the musculoskeletal lesions.
