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).

Outcomes of acetabular fractures treated with acute fix and replace versus open reduction and internal fixation in elderly population: a multicentric retrospective study.

PURPOSE: The optimal operative treatment for displaced acetabular fractures in elderly population is still object of debate. Acute fix and replace procedure, the so called "combined hip procedure" (CHP), was introduced because of the poor results of the open reduction and internal fixation (ORIF) alone. The aim of the study is to compare clinical outcomes of CHP and ORIF alone for the treatment of acetabular fractures in elderly patients. METHODS: This is the largest multicentric retrospective analytical study, with a case-control design on the issue. Hospital records and clinical notes were reviewed to collect demographic, peri-operative, and clinical data. RESULTS: A total of 45 patients met the inclusion criteria: 24 patients entered the CHP group whereas 21 entered the ORIF control group. The mean age was 69.5 + - 1.12 years in the ORIF group and 73.4 + - 1.84 in the control group. The most frequent traumatic mechanism was the fall from same level in both groups (37.5% CHP; 42.9% ORIF). Operating time was significantly lower in the CHP group compared to the ORIF group (207 + - 11.0 ORIF; 175 + - 9.16 CHP; p < 0.05). Moreover, full weight-bearing was allowed significantly earlier in the CHP group compared to ORIF alone (37.3 + - 1.59 ORIF; 32.5 + - 1.69 CHP; p < 0.05). Among the clinician-completed scores, the HHS at three months was higher in the CHP group (66.3 + - 1.83 ORIF;73.6 + - 2.09 CHP; p < 0.05). All the other clinical outcomes were similar in both study groups. CONCLUSION: CHP is desirable treatment option in elderly patients with acetabular fracture when there are poor expected outcomes in terms of joint survival with ORIF alone.

Gibson approach and surgical hip dislocation according to Ganz in the treatment of femoral head fractures.

BACKGROUND: The purpose of the study is to evaluate clinical and radiological outcomes in those patients with femoral head fracture, treated with open reduction and internal fixation through Gibson approach and Ganz flip trochanter osteotomy. The treatment of Pipkin fractures is very challenging, especially for small trauma centers, because of the unusual fracture patterns and high-level surgical skills required. CASE PRESENTATION: Between 2017 and 2020, nine cases of Pipkin fractures came to the Emergency Department at the Trauma Center of our Hospital in Rome. Inclusion criteria were the diagnosis of femoral head fracture, the open reduction and internal fixation as surgical choice and at least 24 months follow-up. Patients older than 65 years and those treated through total hip replacement or combined hip procedure (CHP) were excluded. Thus, five patients were included in our case series. The clinical outcome was evaluated according to Western Ontario and McMaster Universities Arthritis Index, Vail Hip score, modified Harris Hip score and Merle D'Aubignè Postel score. Radiographic assessment was scored according to Epstein-Thompson classification and heterotopic ossification was assessed through Brooker classification. The mean follow-up was 24 months (range 12-24). Average modified Harris Hip score was 92.1 points (range 75.9-100), and the average Vail score was 81.8 (range 55-95). WOMAC score was assessed in three different subscales, pain (A), stiffness (B) and physical condition (C), with the following results: 1.4 A (range 0-7), 1.2 B (range 0-6) and 6.4 C (range 0-22). Merle d'Aubignè Postel score resulted excellent for four patients and good for one patient. According to Epstein-Thompson score of the radiological outcome, four patients showed a good result and one a fair result. No mechanical or infective complications occurred in the five patients. CONCLUSIONS: Gibson's approach and surgical hip dislocation through Ganz trochanteric flip osteotomy allow a good exposure of the femoral head and acetabulum, giving us the possibility to perform an anatomical reduction of the fracture. In our case series, satisfactory clinical and radiological short-term results were obtained without significant complications.

Combination of low-contact cerclage wiring and osteosynthesis in the treatment of femoral fractures.

BACKGROUND AND PURPOSE: Objectives were (1) to evaluate results after cerclage wiring technique for femoral primary and periprosthetic fracture (PPF); (2) to report the incidence of complications and their treatment; (3) to analyze possible prognostic factors. PATIENTS AND METHODS: We analyzed 54 patients treated with different techniques associated with low-contact cerclage wires for femoral fracture. Fractures were stratified according to AO, Vancouver or Rorabeck classification. Cerclage was used as an exclusive implant in four PPFs or combined with internal devices in 50 cases. Comorbidities were assessed using Charlson Comorbidity Index. The Glasgow Outcome Scale was used to compare activities of daily living pre/postoperatively. RESULTS: Cerclage wires with three or four spacers were used in 22 and 32 cases, respectively. Nine patients died within 6 months. Mean follow-up of the remaining 42 patients was 10.5 months. Fracture healing was achieved in 38/42 patients (71 %), with a mean time to callus formation of 57 days and to radiographic union of 3 months (1.5-9 months). Four patients had nonunion. Survival to major complications was 92 and 70 % at 1 and 2 years, respectively, significantly better in cerclage wires with three spacers than those with four spacers (p = 0.0188). No other statistical correlations were found. CONCLUSION: Cerclage wiring in difficult femoral fractures offers minimally invasive reduction and fixation technique, low cost and early holding. We reinforce the concept of "reduce with cerclage cables first, then nail" for displaced long subtrochanteric fractures and support the use of cerclage wiring for challenge PPF using low-contact wires. LEVEL OF EVIDENCE: Therapeutic study, Level IV.

Past and present of the use of cerclage wires in orthopedics.

Cerclage wiring is a simple technique that has been practiced widely since the advent of surgical treatment of fractures. Many studies have reported the use of various cerclage technologies with a wide range of results and clinical applications. The increasing numbers of periprosthetic fractures have led to a revival of interest for this simple technique. When cerclages function as implants, they may be used alone or together with a protecting device such as external or internal splints (such as plates, nails, stems of prosthesis or a combination of thereof). This article presents a review of the available literature relating cerclage-wiring techniques and updates the recommendations for clinical use.

Effectiveness of the Dynamic Internal Fixator System in Metaphyseal and Epiphyseal Femoral Fractures: 10 Years of Experience and Future Expectations.

Angular stability plates are largely used for treating complex fractures, but the incidence of nonunion is high. The innovative dynamic internal fixator (DIF) system is comprised of a plate with angular stability that combines the principles of internal fixator with dynamic device. In this study, we evaluate the feasibility of surgical reconstruction using the DIF in adult patients with epiphyseal-metaphyseal femur fractures and examine complications and outcomes at long-term follow-up. We retrospectively analyze 26 patients (14 females and 12 males), with a mean age of 64 yr, who were treated for femoral fractures between 2008 and 2017. Primary fractures were stratified according to the Muller AO Classification of fractures (mostly types 33-A3 and 31-A3). One patient was treated for a periprosthetic fracture and another for the early breakage of a conventional plate. Mean overall follow-up was 4.3 yr. Fracture healing with complete bony consolidation was achieved in 25 of 26 patients (96%). Two patients experienced complete union after revision surgery. The mean time to bridging callus formation was 58 d (range, 41 d to 4 mo) and to radiographic union was 4.6 mo (range, 1.2 to 12.5 mo). Dynamization of the system was performed in 16 cases. The following major complications occurred in 15% of cases: wound dehiscence (1), nonunion (2), and deep infection (1). No implant breakdowns were observed. The DIF system merged the advantages of angular stability plates with the possibility of dynamization, increasing fracture site compression to modulate and guarantee the healing process.
