Age is Associated with Level of First-Time Anterior Cervical Discectomy and Fusion: An Ordinal Analysis of Factors Influencing Timing of Cervical Degeneration.

BACKGROUND: Symptomatic cervical spondylosis is often treated with anterior cervical discectomy and fusion (ACDF). However, few factors can predict which cervical level will degenerate and require intervention. This analysis evaluates preprocedural factors associated with level of first-time single-level ACDF. METHODS: We performed a retrospective analysis of patients who underwent single-level ACDF without prior history of spine surgery. Mann Whitney U-tests and Spearman rank-order correlation were performed for analyses of associations between variables of interest and ACDF level. Adjusted odds-ratios were calculated by proportional-odds logistic regression, with age, sex, body mass index, current tobacco use, history of neck trauma, preoperative radicular symptoms, and preoperative myelopathic symptoms as covariates. RESULTS: One hundred forty-one patients met inclusion criteria, and age demonstrated a negative correlation with ACDF level, such that younger patients tended to have ACDF performed at inferior subaxial levels (P = 0.0006, rho = -0.31, moderately strong relationship). Patients with preoperative radicular symptoms and myelopathic symptoms were more likely to have ACDF performed at inferior (P = 0.0001) and superior (P < 0.0001) levels, respectively. Patient sex, body mass index, current tobacco use, and history of neck trauma were not predictive of ACDF level. When adjusting for the above variables in a proportional-odds ordinal logistic regression model, a one-year increase in age conferred a 4% increase in the odds of requiring an ACDF at a given superior level compared to the adjacent inferior level. CONCLUSIONS: Age is correlated with level of first-time single level ACDF. Individual subaxial levels may have unique biomechanical properties that influence degeneration.

Subtle Syndesmotic Instability.

Latent or subtle syndesmotic instability is defined as an injury to the syndesmosis which is not apparent on static radiographs of the ankle. Syndesmotic injuries have also been referred to as high ankle sprains. Injury to the syndesmosis typically occurs with collision sports and often involves an external rotation force to the ankle. Diagnosis can be delayed because of negative initial imaging studies. Physical examination tests including the external rotation test, proximal squeeze test, and fibular shuck test can assist in the diagnosis. Advanced imaging modalities such as MRI and weight-bearing CT have been studied and can provide prognostic indications for management, although arthroscopic stress evaluation remains the benchmark for diagnosis. Both surgical and nonsurgical management techniques have been described, which can assist patients in returning to their preinjury level of function.

Internal Joint Stabilizer: A Safe Treatment for Traumatic Elbow Instability.

OBJECTIVES: To report early results of the "Internal Joint Stabilizer of the Elbow" (IJS-E) in the treatment of terrible triad injuries and other unstable traumatic elbow dislocations. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Seventeen patients with traumatic elbow instability treated with IJS-E over a 2-year period; 7 of whom sustained terrible triad-type injuries. INTERVENTIONS: Open reduction internal fixation with the "IJS-E". MAIN OUTCOME MEASURES: Elbow stability and arc of motion were assessed radiographically and clinically. Disabilities of the Arm, Shoulder and Hand scores were collected by telephone. RESULTS: All elbows were radiographically stable at the time of IJS-E removal. Mean time of follow-up was 9 months from index operation (range, 2.5-24 months). Mean elbow arc of motion was restored to flexion-extension 92 degrees (range, 5-125; SD, 31 degrees) and forearm pronation-supination 139 degrees (range, 0-180; SD, 48 degrees). Mean Disabilities of the Arm, Shoulder and Hand score was 22.2 (range, 7.5-45.7; SD, 13.3) for patients at least 1 month from surgery on the ipsilateral extremity. Five patients (30%) developed complications, and -2 (12%) required revision for implant failure. CONCLUSIONS: The IJS-E offered reliable treatment of traumatic elbow instability, particularly terrible triad-type injuries. It permited early range of motion and was effective in restoring elbow stability. We believe that the use of this relatively novel system should be further explored. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Percutaneous screw fixation of pubic symphysis disruption: A preliminary report.

BACKGROUND: Percutaneous techniques are commonly used to treat pelvic ring disruptions but are not mainstream for fixation of pubic symphysis disruption worldwide. Potential advantages include less blood loss and lower risk of surgical site infection, especially in the morbidly obese or multiply injured patient. This study was performed to describe the clinical and radiographic outcomes of patients after percutaneous reduction and screw fixation of pubic symphysis disruption and to evaluate the preliminary safety and efficacy of this technique and its appropriateness for further study as an alternative method of fixation. METHODS: A retrospective review was performed to identify all patients who underwent percutaneous fixation of pubic symphysis disruption by two surgeons at an academic Level I trauma center over a 3-year period. Patients underwent percutaneous reduction and fixation of the pubic symphysis using 1 or 2 fully or partially threaded 5.5, 6.5, or 7.3 mm cannulated screws in a transverse or oblique configuration. Associated posterior ring injuries were fixed with trans-sacral and/or iliosacral screws. The primary outcome of interest was loss of reduction, defined as symphysis distance greater than 15 mm measured on final AP pelvis radiograph. Secondary outcomes collected by chart review were operative time, blood loss, vascular or urologic injury, sexual dysfunction, infection, implant loosening or breakage, and revision surgery. RESULTS: Twelve patients met criteria and primary and secondary outcomes were collected. Mean clinical and radiographic follow-up were 15 months each. One patient lost reduction. Mean operative time and blood loss were 124 min and 29 cc, respectively. No vascular or urologic injuries occurred. Two patients reported sexual dysfunction. No patients became infected or required revision surgery. Four patients underwent implant removal. Seventeen additional patients were excluded due to short follow-up and limited outcomes were collected. Two of these patients lost reduction. Three underwent implant removal. CONCLUSION: These data support percutaneous reduction and screw fixation of pubic symphysis disruption as a potentially safe and effective method of treatment that warrants further investigation.

Group trauma-focused cognitive-behavioural therapy with former child soldiers and other war-affected boys in the DR Congo: a randomised controlled trial.

BACKGROUND: The Democratic Republic of Congo (DRC) has been home to the world's deadliest conflict since World War II and is reported to have the largest number of child soldiers in the world. Despite evidence of the debilitating impact of war, no group-based mental health or psychosocial intervention has been evaluated in a randomised controlled trial for psychologically distressed former child soldiers. METHOD: A randomised controlled trial involving 50 boys, aged 13-17, including former child soldiers (n = 39) and other war-affected boys (n = 11). They were randomly assigned to an intervention group, or wait-list control group. The intervention group received a 15-session, group-based, culturally adapted Trauma-Focused Cognitive-Behavioural Therapy (TF-CBT) intervention. Assessment interviews were completed at baseline, postintervention and 3-month follow-up (intervention group). RESULTS: Analysis of Covariance (ANCOVA) demonstrated that, in comparison to the wait-list control group, the TF-CBT intervention group had highly significant reductions in posttraumatic stress symptoms, overall psychosocial distress, depression or anxiety-like symptoms, conduct problems and a significant increase in prosocial behaviour (p < .001 for all). Effect sizes were higher when former child soldier scores were separated for sub-analysis. Three-month follow-up of the intervention group found that treatment gains were maintained. CONCLUSIONS: A culturally modified, group-based TF-CBT intervention was effective in reducing posttraumatic stress and psychosocial distress in former child soldiers and other war-affected boys.

Screening for traumatic exposure and psychological distress among war-affected adolescents in post-conflict northern Uganda.

BACKGROUND: The war in northern Uganda has had a debilitating effect on the mental health of children and adolescents in the population. This study measures the prevalence and considers the aetiology of psychological distress in war-affected adolescents 4 years after the end of the conflict. METHODS: This is a cross-sectional study of 205 adolescents, aged 12-19, from a boarding primary school in Gulu, northern Uganda. A war experiences checklist was developed with the assistance of local professionals. The Impact of Event Scale-Revised (IES-R) measured post-traumatic stress symptoms. Finally, the Acholi Psychosocial Assessment Instrument (APAI) was used to measure locally described mental health constructs similar to the Western concepts of depression and anxiety. RESULTS: Four years after the end of the war, 57% of the students were still found to have clinically significant levels of post-traumatic stress symptoms using a similar cut-off score to previous studies among the same population. Both components of traumatic exposure: (i) the number of types of traumatic event experienced; and (ii) whether the adolescent was abducted were significantly associated with psychological distress. There was a strong correlation between post-traumatic stress symptoms and internalising symptoms. CONCLUSION: War-affected adolescents may continue to suffer from significant psychological stress in the years following the cessation of conflict. Multiple exposure to a number of different types of traumatic event may directly increase the likelihood of psychological distress especially for those exposed to the most extreme violence. The feasibility of employing a locally developed and validated screening instrument is demonstrated. Implications for future research and intervention in post-conflict areas are considered.
