Is magnetic resonance imaging needed for decision making diagnosis and treatment of thoracic and lumbar vertebral fractures?

PURPOSE: The radiological examination including plain radiography, CT and MRI are critical to assess the severity of the instability, to diagnose the fracture type and to select the appropriate treatment strategy for the thoracic and lumbar vertebral fractures. The aim of this prospective observational study was to investigate the effect of magnetic resonance imaging (MRI) on decision making for the diagnosis and treatment of acute thoracic and lumbar vertebral fractures. METHODS: Consecutive 180 patients with acute thoracic and/or lumbar vertebral fractures were included in the study. The fracture pattern was evaluated by using initial radiographs, computed tomography (CT) and MRI within 24 h of trauma. Fractures were classified according to AO classification before and after MRI. TLICS classification was also used to decide treatment plan. MRI findings were compared to surgical findings in the surgically treated patients. RESULTS: A significant moderate agreement was found between Xray + CT and post-MRI classifications for all fracture types (Kappa = 0.511; p < 0.001). In 101 patients with new findings on MRI, a significant moderate correlation was observed between Xray + CT and post-MRI classifications in the fracture re-classification (Kappa = 0.441, p < 0.001). There was a significant change in the treatment plan of patients with new findings on MRI according to Xray + CT (p < 0.0001). After MRI evaluation, the treatment plan changed in favor of surgery in 33.9% of patients who were scheduled for conservative treatment according to Xray + CT (p < 0.0001). CONCLUSION: Since MRI assessment of acute thoracic and/or lumbar injuries has led to a remarkable treatment change decision that confirms intraoperative findings of the patients who were decided to undergo surgery, MRI should be obtained in thoracic and lumbar vertebral fractures, regardless of the CT and plain radiographic findings. LEVEL OF EVIDENCE: Level II, prospective observational study.

Could percutaneous fixation with crossed Schanz pins be an alternative to open reduction in the treatment of intra-articular calcaneal fractures?

PURPOSE: Despite modern operative techniques and a considerable number of studies in the literature, the best treatment for calcaneal fractures remains an enigma for orthopaedic surgeons. The purpose of the study was to compare clinical and radiographic outcomes between anatomic calcaneal plate (ACP) fixation and crossed Schanz pin (CSP) fixation in the treatment of Sanders type II and III displaced intra-articular calcaneus fractures (DICFs). METHODS: Consecutive 65 patients (49 males, 16 females) who underwent surgery for DCIFs between January 2009 and February 2013 were retrospectively evaluated. The patients were divided into two groups as ACP and CSP according to the operative technique. The groups were compared in terms of demographic features, injury mechanism, operation time, fluoroscopy exposure, complications, full weight-bearing time, functional, and radiological outcomes. RESULTS: VAS-rest score did not differ significantly between the groups while the VAS-activity score was significantly higher in the CSP group (p = 0.001 and p = 0.645, respectively). Foot Function Index (FFI) was significantly lower, Maryland Foot Score (MFS) and the American Orthopaedic Foot and Ankle Society-hindfoot score (AOFAS) were significantly higher in the ACP group (p = 0.047, p = 0.016, and p < 0.001, respectively). While no difference was observed between the preoperative and the early post-operative (1st day) Böhler angle and Gissane angle, both were significantly higher in the ACP group at the post-operative last control (p < 0.001 and p < 0.001, respectively). CONCLUSION: Although crossed Schanz pin fixation shortens the operation time in displaced intra-articular calcaneus fractures compared to anatomic calcaneal plate, increased fluoroscopy exposure rates and low functional and radiological outcomes are disadvantageous of crossed Schanz pin. Anatomic calcaneal plate is still a better technique for preserving the alignment and elevating the displaced intra-articular segment for good to excellent mid-term results.

The impact of proximal femoral nail type on clinical and radiological outcomes in the treatment of intertrochanteric femur fractures: a comparative study.

PURPOSE: The aim of the study was to compare three different proximal femoral nails in terms of functional and radiological outcomes in patients treated with closed reduction and internal fixation for intertrochanteric femur fractures (IFFs). METHODS: Between February 2010 and March 2016, 303 consecutive patients (132 male, 171 female) were included in the study. The groups were compared in terms of age, gender, body mass index, duration of surgery and duration of fluoroscopy, blood loss, type of fracture and quality of the reduction, complication rate, and functional and radiological results. Harris hip score (HHS), Barthel index, and full weight bearing time were used for functional evaluation. The quality of the reduction, collodiaphyseal angle (CDA), tip-apex distance (TAD), and fracture union were used for radiological results evaluation. RESULTS: There was no significant difference between groups in terms of fracture type, reduction quality, and complication rates. The mean operation time, duration of scopy, blood loss, and TAD was higher for InterTan, whereas the mean postoperative CDA was higher for PFNA-II. Operation time, postoperative CDA, and full weight bearing duration were higher for Profin than for InterTan. The mean HHS and Barthel Index were higher for PFNA-II, while the mean duration of operation and fluoroscopy, blood loss, TAD, and full weight bearing time were higher for Profin. CONCLUSION: PFNA-II is a better option than Profin and InterTAN in the treatment of IFFs when the surgical parameters and functional and radiological results were evaluated as a whole.

The relationship between injury mechanism and sexual dysfunction in surgically treated pelvic fractures.

PURPOSE: The aim of the study was to identify the incidence of new sexual dysfunction reported by the patient in surgical treatment of pelvic ring injuries, and to describe the relationship between new sexual dysfunction and type of fracture. METHODS: Ninety-five patients who were operated for pelvic fracture were included in the study. Patients were evaluated according to age, gender, marital status, body mass index, trauma mechanism, fracture classification, genitourinary injury, accompanying injury, injury severity score, surgical technique, fixation material, duration of operation, functional outcomes, blood loss, complications, and sexual dysfunction. Functional outcomes were assessed with Female Sexual Functioning Index (FSFI), International Index of Erectile Function-5 (IIEF5), Arizona Sexual Experience Scale (ASEX), and Modified Majeed's pelvic outcomes grading scale (MPS). RESULTS: Genitourinary symptoms were erectile dysfunction (ED) in 13 men, ejaculatory dysfunction in 9 men, and dyspareunia in 23 women. Urethral stricture developed in 4 males and 1 female with the urethral injury. FSFI score, ASEX score, and MPS score showed the statistically significant difference between the fracture types (p = 0.021, p = 0.032 and p = 0.020, respectively). There were no significant difference between fracture types in terms of the IIEF5 score, and no significant relationship between fracture type and ED development (p = 0.141). CONCLUSION: Anteroposterior compression (APC) is the most common cause of sexual dysfunction in both sexes, independent of surgery. In addition, the most common cause of ED in men is vertical shear (VS). Especially patients with APC and VS injuries should be multidisciplinary evaluated with gynecology, urology, and psychiatry departments.

Importance of lowest instrumented vertebra on clinical and radiological outcomes in patients with Lenke type 3C adolescent idiopathic scoliosis: a minimum 4-year follow-up.

The purpose of this retrospective study was to determine the most appropriate distal fusion level in terms of clinical results and radiological changes in Lenke 3C adolescent idiopathic scoliosis (AIS). Between June 2010 and May 2014, a total of 90 consecutive patients who underwent surgery for Lenke 3C AIS were divided into three groups as L2, L3, and L4 according to the fusion levels and compared in terms of functional and radiological outcomes. Patients were evaluated with Scoliosis Research Society 22 (SRS 22) and the Oswestry disability index (ODI) at the final follow-up. Preoperative standard posteroanterior and lateral whole-spine radiographs and lateral bending radiographs were used to evaluate the curves. All patients were also assessed with lumbar MRI at the final follow-up, and classified for each patient in terms of disc degeneration (DD) and facet joint degeneration (FJD). There was a statistically significant difference between the groups in terms of ODI category (P = 0.001). The rate of minimal disability in the L3 group, moderate disability in the L2 group, and severe disability in the L4 group were higher. Statistically significant differences were observed between the groups in terms of pain, body image, mental health, and total score distribution from the SRS-22 domains (P < 0.05). No significant difference was observed between the groups in terms of DD and FJD in MRI (P = 0.263). Although the preoperative functional scores could not be evaluated due to the retrospective nature of the study, it was observed that the only significant difference between the groups was the SRS-22 score. The best SRS-22 score was obtained in patients in whom fusion was stopped at L3.

The role of trauma mechanism, fracture pattern and fixation technique on clinical outcomes and epiphyseal growth arrest in the surgical treatment of distal tibial epiphysiolysis.

BACKGROUND: Distal tibial epiphyseal fractures damage to epiphyseal growth plate. Epiphyseal growth arrest (EGA), reflex sympathetic dystrophy and ankle joint stiffness may also occur after distal tibial epiphyseal injury. This study aims to evaluate the role of trauma mechanism, fracture pattern and fixation technique on clinical outcomes and EGA in the surgically treated distal tibial epiphyseal fractures. METHODS: Twenty seven patients who underwent surgery for distal tibial epiphyseal fracture between the 2011 and 2017 were evaluated retrospectively. The effects of trauma mechanism, fixation technique, preoperative duration, fracture patterns on the clinical results and EGA were examined. AOFAS (The American Orthopedic Foot and Ankle Score) and MOXFQ (The Manchester-Oxford Foot Questionaire) were used for clinical evaluation. RESULTS: Twenty seven patients (17 male and 10 female) were included in this study. The most important complication of epiphyseal injury was the growth pause in eight patients. No statistically significant difference was observed concerning clinical scores and complications according to trauma mechanism, fixation techniques and fracture patterns (p>0.05). CONCLUSION: Regardless of the trauma mechanism, fracture pattern and the fixation material, an anatomical reduction should be obtained in distal tibial epiphyseal fractures to reduce complications and prevent the EGA.
