PLATE FIXATION OF ODONTOID FRACTURES WITHOUT C1–C2 ARTHRODESIS

Abstract OBJECTIVE Surgical treatment of odontoid fractures that do not allow interfragmentary fracture compression involves either posterior atlantoaxial arthrodesis or additional anterior stabilization using a plate construct. The purpose of this study was to determine the clinical and radiographic outcome after anterior plate fixation of odontoid fractures that were not suitable for anterior screw fixation. METHODS We reviewed the clinical and radiographic records of 9 patients with an average age of 54 years at the time of surgery who had undergone anterior plate fixation of an odontoid fracture. Indications for using a plate construct were odontoid fractures with anterior oblique fracture lines, fractures with comminution or major displacement, and pathological fractures. RESULTS Eight patients returned to their preinjury activity level and were satisfied with their treatment. One patient reported chronic pain symptoms and a notable decrease in cervical spine motion. Using the Smiley-Webster Scale to quantify their clinical outcome, we achieved an overall outcome score of 1.6. Bony fusion was achieved in all patients. Reduction or fixation failed in 2 patients. Reoperation for technical failures was not necessary in any of the patients. CONCLUSION We had promising results using anterior plate fixation for surgical treatment of odontoid fractures that did not allow interfragmentary fracture compression. Because this method avoids the rigid fixation of the atlantoaxial joint in contrast to techniques of posterior cervical arthrodesis, it seems to be a practical option for the management of fracture types that require additional stabilization of the odontoid.

Displaced Fracture

BACKGROUND Displaced odontoid fractures that are irreducible with traction and have cervicomedullary compression by the displaced distal fracture fragment or deformity caused by facetal malalignment require early realignment and stabilization. Realignment with ultimate solid fracture fusion and atlantoaxial joint fusion, in some situations, are the aims of surgery. Fifteen such patients were treated with direct anterior extrapharyngeal open reduction and realignment of displaced fracture fragments with realignment of the atlantoaxial facets, followed by a variable screw placement (VSP) plate in compression mode across the fracture or anterior atlantoaxial fixation (transarticular screws or atlantoaxial plate screw construct) or both. OBSERVATIONS Anatomical realignment with rigid fixation was achieved in all patients. Fracture fusion without implant failure was observed in 100% of the patients at 6 months, with 1 unrelated mortality. Minimum follow-up has been 6 months in 14 patients and a maximum of 3 years in 4 patients, with 1 unrelated mortality. LESSONS Most irreducible unstable odontoid fractures can be anatomically realigned by anterior extrapharyngeal approach by facet joint manipulation. Plate (VSP) and screws permit rigid fixation in compression mode with 100% fusion. Any associated atlantoaxial instability can be treated from the same exposure.

Clavicular fractures are common in sport practice, they are easily diagnosed and have a relative good forecast. Nevertheless there is no consensus among orthopedic surgeons regarding treatment for displaced midle-third clavicular fractures (Robinson’s classification 2B2) and lateral-third fractures. The tendency toward operative treatment is increasing due to the earlier sport recovery. Objectives: The aim of the paper is to present the results of treatment of 98 clavicular fractures in the Clinic Gastaldi of Traumatology during the period from 1997 to 2016, analyzing the radiologic and clinical results. Methods: The serie consists of 89 patients, 80 males and 9 females, average age 32.2 years. From them, 89 were agude fractures and 9 nonunion (after conservative treatment). According to the Thomsom classification there were 82 middle-third and 16 lateral-third. Motorbike sport trauma was the cause of 49 patients (55%), bike trauma in 18 (20%), 18 (20%) fractures occurred due to contact sports and 3 other causes. All patients were surgically treated. We used an antero-superior approach, open reduction and internal fixation with antero-superior plate osteosynthesis. In case of nonunion we decorticated the fracture callus, adding intramedullary reaming and graft bone. PRP (Platelet Rich-Plasma) was used in 8/9 patients. Postoperatively, the patients were placed in a sling. After that they began a rehabilitation program that consists of isometrics, pendular and active movements until 45° during 3 weeks. From 4th to 6th week, active movements until 90°. The patients began free movements after the 6th week. Results: Fracture healing mean was 10 weeks. Bikes and motorbikes were able to ride again between 10 to 21 days after surgery (once removed stitches). All patients retrieved full shoulder range of motion and returned to their previous activity level. Complications: we had no nonunion rates after surgical treatment, neither infections. 1 case of insufficient plate fixation and 4 re-fractures which required surgical treatment. Conclusion: We suggest surgical treatment for clavicular fractures in adult patients, contact sports with IIB and IIIB fractures, re-fractures and painful nonunion. Surgical treatment with open reduction and internal fixation (ORIF) of displaced middle-third clavicular fractures achieved shorter time to complete return to sport and earlier bone union.

Abstract OBJECTIVE Despite various reports in the literature, the appropriate treatment of Type II odontoid fractures remains controversial. Although there is an increasing tendency toward surgical treatment of these fractures in recent years, nonoperative treatment strategies are still regarded as a practicable method, particularly in elderly patients with significant comorbidities. One purpose of this study was to determine the functional and radiographic long-term results after rigid immobilization of Type II odontoid fractures using a halothoracic vest. The second aim was to present a case-control series of patients with nonunion of Type II odontoid fractures compared with patients with successful fracture healing to determine specific risk factors for failure of halo immobilization. METHODS We reviewed the clinical and radiographic records of 90 patients with an average age of 69 years at the time of injury who had undergone nonoperative treatment of odontoid fractures using a halothoracic vest between 1988 and 2004. To identify potential risk factors for failure of halo fixation, patients were divided into “cases” and “controls.” Cases were defined as patients with nonfusion after halo immobilization, and controls were patients with successful fracture healing attained with this treatment option. RESULTS Seventy-five patients returned to their preinjury activity level and were satisfied with their treatment. The Smiley-Webster scale showed an overall functional outcome score of 1.64. Successful fracture healing was achieved in 76 patients (84%). In 14 patients, nonunion was diagnosed by standard x-rays and additional computed tomographic scans within 6 to 12 months after trauma. Referring to possible risk factors for failure of halo fixation, nonunion was found significantly more often in older patients and in those with displaced fractures of the odontoid. Secondary loss of reduction and delay of treatment were identified as further risk factors for nonfusion. CONCLUSION With regard to successful fracture healing and functional results of the patients, we had a satisfactory outcome after halo fixation of Type II odontoid fractures. Although a fusion rate of 84% should not be deemed as optimal, nonoperative management of these fractures using a halothoracic vest seems to be an appropriate treatment strategy in patients who are not suitable for surgical treatment.

We present a rare clinical case of a 90-year-old female who sustained a proximal femoral neck fracture following long-standing hip arthrodesis. Since the fracture occurred relatively proximally and involved the pelvis, double-plate fixation was chosen to achieve rigid fixation. The reconstruction plate was placed at the posterior and anterior columns individually through single vertical incision. She was treated successfully, and she attained preinjury activity level. Proximal femoral fractures in arthrodesed hips need to be recognized as a fracture between the pelvis and femur. Rotational stress from the trunk and lower extremity requires rigid fixation to minimize the increase of displacement and the risk for nonunion.

Fracture Compression

Odontoid fractures comprise as many as 20% of all cervical spine fractures. Fractures at the dens base, classified by the Anderson and D’Alonzo system as Type II injuries, are the most common pattern of all odontoid fractures and are also the most common cervical injuries in patients older than 70 years of age. Surgical treatment is recommended for patients older than 50 years with Type II odontoid fractures, as well as in patients at a high risk for nonunion. Anterior odontoid screw fixation (AOSF) and posterior cervical instrumented fusion (PCIF) are both well-accepted techniques for surgical treatment but with unique indications and contraindications as well as varied reported outcomes. In this paper, the authors review the literature about specific patients and fracture characteristics that may guide treatment toward one technique over the other. AOSF can preserve atlantoaxial motion, but requires a reduced odontoid, an intact transverse ligament, and a favorable fracture line to achieve adequate fracture compression. Additionally, older patients may have a higher rate of pseudarthrosis using this technique, as well as postoperative dysphagia. PCIF has a higher rate of fusion and is indicated in patients with severe atlantoaxial misalignment and with poor bone quality. PCIF allows direct open reduction of displaced fragments and can reduce any atlantoaxial subluxation. It is also used as a salvage procedure after failed AOSF. However, this technique results in loss of atlantoaxial motion, requires prone positioning, and demands a longer operative duration than AOSF, factors that can be a challenge in patients with severe medical conditions. Although both anterior and posterior approaches are acceptable, many clinical and radiological factors should be taken into account when choosing the best surgical approach. Surgeons must be prepared to perform both procedures to adequately treat these injuries.

And Function

Background: In the treatment of anterior cruciate ligament (ACL) injuries, there is little evidence of when and why a decision for ACL reconstruction (ACLR) or nonoperative treatment (non-ACLR) is made. Purpose: To (1) describe the key characteristics of ACL injury treatment decisions and (2) compare patient-reported knee instability, function, and preinjury activity level between patients with non-ACLR and ACLR treatment decisions. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 216 patients with acute ACL injury were evaluated during the first year after injury. The treatment decision was non-ACLR in 73 patients and ACLR in 143. Reasons guiding treatment decision were obtained from medical charts and questionnaires to patients and orthopaedic surgeons. Patient-reported instability and function were obtained via questionnaires and compared between patients with non-ACLR and ACLR treatment decisions. The ACLR treatment group was classified retrospectively by decision phase: acute phase (decision made between injury day and 31 days after injury), subacute phase (decision made between 32 days and up to 5 months after injury), and late phase (decision made 5-12 months after injury). Data were evaluated using descriptive statistics, and group comparisons were made using parametric or nonparametric tests as appropriate. Results: The main reasons for a non-ACLR treatment decision were no knee instability and no problems with knee function. The main reasons for an ACLR treatment decision were high activity demands and knee instability. Patients in the non-ACLR group were significantly older ( P = .031) and had a lower preinjury activity level than did those in the acute-phase ( P < .01) and subacute-phase ( P = .006) ACLR decision groups. There were no differences in patient-reported instability and function between treatment decision groups at baseline, 4 weeks after injury, or 3 months after injury. Conclusion: Activity demands, not patient-reported knee instability, may be the most important factor in the decision-making process for treatment after ACL injury. We suggest a decision-making algorithm for patients with ACL injuries and no high activity demands; waiting for >3 months can help distinguish those who need surgical intervention from those who can undergo nonoperative management.

Objectives: To study the measurement properties, the responsiveness and the minimal clinically important difference of the ENDOPAIN-4D: a new questionnaire for assessing pain in endometriosis. Methods: A prospective, observational, multicentre study was conducted including all women ≥18 years consulting for symptomatic proven endometriosis between 1 January 2017 and 30 June 2018 and volunteering to participate. Each patient had to answer a new self-administered patient-reported outcome (PRO) questionnaires (the ENDOPAIN-4D) at inclusion (T0) and 12 months after medical or surgical treatment (T1). Criteria defined by COSMIN were used to validate the questionnaire's measurement properties. The minimal clinically important difference was estimated by the anchor-based method. Results: The study included 199 women. The ENDOPAIN-4D score had a four dimensional structure with good internal consistency (measured by Cronbach α): I) pain-related disability (α = 0.79), II) painful bowel symptoms (α = 0.80), III) dyspareunia (α = 0.83), and IV) painful urinary tract symptoms (α = 0.77). They produced four subscores that can be summed to obtain a single score (α = 0.61). The ENDOPAIN-4D total score ranged from 0 to 94.00 (mean ± SD: 46.7 ± 22). The total score was significantly correlated with the PROs used in endometriosis. Sensitivity to change was good with large effect sizes (ES) (mean of the differences: 36.3 p = 1.8 10−7, ES 0.76). The minimal clinically important difference of the global score was determined to be 10.9. Conclusions: The ENDOPAIN-4D questionnaire is easy to use, valid, and effective in assessing patient reported pain symptoms in women treated for endometriosis. This new instrument can be used as the primary outcome for future clinical trials and as a tool for routine patient follow-up.

Background:The patient-reported outcomes are important components of quantitative methods of rheumatoid arthritis (RA) activity assessment which are used to choose the appropriate drug therapy. The value of these parameters can be significantly affected not only by the inflammatory process, but also by the psychological characteristics of the patient and, in particular, by hardiness [1].Objectives:To study the relationship between psychological factors and signs of RA activity.Methods:Patients with RA who met the EULAR/ACR 2010 criteria, and observed at the V. A. Nasonova Research Institute of Rheumatology were included. Clinical examination was performed including patient global assessment (PGA), physician global assessment (PhGA), pain measurement on a visual analog scale, tender joint count (TJC), swollen joint count (SJC). The functional status was determined by HAQ, the quality of life – by SF-36 EQ-5D, the nature of pain – by painDETECT, the presence of anxiety and depression – by HADS. Patients also completed Hardiness Survey questionnaire to assess hardiness (HDS) and 3 components of the HDS – commitment (CMT), control (CT) and challenge (CLN). Disease activity was evaluated with DAS28, CDAI, and RAPID3. All patients signed informed consent to participate in the study. Analysis of the data was performed using Spearman’s rank test, Fisher exact test, qui-square and t-tests.Results:85 patients with RA were included. There were 69 women and 16 men. Mean age was 56.7±13.1 years, disease duration – 7.6±2.7 years. 72 patients were positive for rheumatoid factor, 75 – for anti-cyclic citrullinated peptide antibody. CDAI showed high activity in 15, moderate – in 37, low – in 30, and remission in 3 patients, DAS 28 – in 10, 55, 12, and 8, and RAPID3 – in 24, 25, 15, and 21, respectively. 24 patients had subclinically or clinically expressed anxiety and 15 –subclinically or clinically expressed depression (≥8 according to HADS). In 31 patients, the painDETECT questionnaire revealed possible or probable neuropathic pain. Mean HDS was 84.8±21.7, CMT – 38.9±9.2, CT – 29.4±8.6, CLN – 17.3±7.1. These values were comparable with the corresponding population data for this age group. There was a significant inverse correlation between HDS and RA activity measures, including SJC, TJC, DAS28 (p<0.05), pain, PGA, PhGA, CDAI, RAPID3, and HAQ (p<0.01). In addition, HDS and all its components positively correlated with quality of life, assessed by SF-36 and EQ-5D (p<0.01). In patients with subclinically and clinically expressed anxiety and depression, HDS, CMT, and CT were significantly lower than in patients without anxiety and depression (p<0.01), while the values of CLN in these groups did not differ significantly.Conclusion:The results of the present study suggest that low HDS may be one of the significant factors determining RA activity level because it does not allow patients to adapt adequately to a stressful situation produced by the disease.References:[1]Maddi SR.
