Ten "tips and tricks" to provide trauma care without residents.

The utilization of medical students, residents, and fellows within the orthopaedic trauma team helps alleviate workload demands. However, many nonacademic hospitals lack these clinical resources. Therefore, orthopaedic trauma surgeons often must be creative in developing alternative methods to better manage time, staff, and patients. Incorporating midlevel providers and maximizing surgical technician assistance are favorable for both the hospital and the patient. In addition, using currently available medical devices in unique and innovative ways can help simplify patient procedures and optimize care. The purpose of this article is to detail precise tips and tricks for overcoming challenges observed during orthopaedic trauma cases when residents are unavailable.

Cervical spine trauma in diffuse idiopathic skeletal hyperostosis: injury characteristics and outcome with surgical treatment.

STUDY DESIGN: Retrospective study of a consecutive series of operatively managed patients with cervical fractures with diffuse idiopathic skeletal hyperostosis (DISH) presenting to 3 institutions over an 8 year period. OBJECTIVE: Assess demographics, fracture characteristics, outcome and complications in patients managed surgically. SUMMARY OF BACKGROUND DATA: Cervical spine injuries related to DISH represent a difficult subgroup of trauma patients to treat. This subset is fraught with potential complications related to the injury of the ankylosed spine, high rate of co-morbidities, and older demographics. The data in the literature on treatment, outcomes and complications is largely comprised of case reports and small case series. METHODS: All patients with cervical fractures in the setting of DISH between January 2001 and December 2008 were reviewed retrospectively. Charts and radiographs were reviewed assessing demographics, injury characteristics and short-term outcomes. Statistical analysis was performed analyzing the impact of distinct parameters on the incidence of medical and surgical complications. RESULTS: Thirty-three patients with age 73.8 ± 11 years were identified. DISH-affected segments numbered 5.5 ± 2.1. Injury severity as assessed by the Subaxial-Injury-Classification scoring-system (SLIC) averaged 7.2 ± 1.4 points. 7 patients (20.6%) were ASIA-A on admission, 4 (11.8%) ASIA-B, 4 (11.8%) ASIA-C, 10 (29.4%) ASIA-D, and 7 (20.6%) ASIA-E. All but 2 patients (6%) had medical co-morbidities. Inpatient stay was 26.6 ± 23.4 days. 16 patients (47%) had anterior, 12 patients (35.3%) had posterior, and 5 patients (14.7%) had combined anterior-posterior instrumented fusion. 25 patients (73.5%) had medical/surgical complications. 20 patients (58.8%) suffered serious pulmonary complications not related to the neurologic injury (p < 0.05). Nine patients (26.5%) had died. Seven patients (20.6%) showed improved ASIA-scores, 18 patients (52.9%) had no improvement and 2 patients (5.9%) deteriorated. CONCLUSION: The current findings pinpoint the potential for medical and surgical complications in this high risk subgroup. Surgeons should be aware of the unique aspects associated with treatment of these injuries.

Pedicle screw instrumentation of thoracolumbar burst fractures: Biomechanical evaluation of screw configuration with pedicle screws at the level of the fracture.

BACKGROUND: Posterior fixation alone may not be adequate to achieve and maintain burst fracture reduction. Adding screws in the fractured body may improve construct stiffness. This in vitro study evaluates the biomechanical effect of inserting pedicle screws in the fractured body compared with conventional short- and long-segment posterior fixation. METHODS: Stable and unstable L2 burst fractures were created in 8 calf spines (aged 18 weeks). Constructs were tested at 8 Nm in the intact state and then with instrumentation consisting of long- and short-segment posterior fixation with and without screws in the fractured L2 vertebral body after (1) stable burst fracture and (2) unstable burst fracture. Range of motion was recorded at L1-3 for flexion-extension, lateral bending, and axial rotation. Statistical analysis was performed with repeated-measures analysis of variance, with significance set at P < .05. The data were normalized to the intact state (100%). RESULTS: Both long- and short-segment constructs with screws in the fractured body significantly reduced motion compared with the stable and unstable burst fracture in flexion-extension and lateral bending. Fracture screws enhanced construct stability by 68% (on average) relative to conventional short-segment posterior fixation and were comparable to long-segment posterior fixation. CONCLUSIONS: Screws at the fracture level improve construct stiffness. Short-segment constructs may suffice for stable burst fractures. More severe injuries may benefit from fracture screws and can be considered as an alternative treatment to long-segment constructs.

Spine fractures in patients with ankylosing spinal disorders.

STUDY DESIGN: Retrospective review. OBJECTIVE: To describe the spine fracture characteristics, current treatments, and their results in patients with ankylosing spinal disorders (ASD), such as ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH), with the hypothesis that complication and mortality rates are high. SUMMARY OF BACKGROUND DATA: Spine fractures in patients with ASD are unique and have only been described in relatively small case series. METHODS: Retrospective review of a large consecutive series of patients with spine fractures and ASD over a 7-year period. Complications were stratified according to parameters such as type and number of comorbidities, patient age, and mechanism of injury. Predictors of mortality were analyzed by linear regression. Similarities between patients with AS and DISH were evaluated by chi analysis. RESULTS: Of the 122 spine fractures in 112 consecutive patients with ASD, the majority were transdiscal extension injuries, most commonly affecting C6-C7. Eighty-one percent of the patients had at least 1 major medical comorbidity. Spinal cord injury was present in 58% of the patients, 34% of whom improved by at least 1 American Spinal Injury Association grade. Nineteen percent of patients had delayed diagnosis of their spine fracture, 81% of whom had resulting neurologic compromise. Surgery was performed on 67% of patients, consisting primarily of multilevel posterior instrumentation 3 levels above and below the injury. Eighty-four percent of all patients had at least 1 complication. Mortality was 32% and correlated with age > or =70 (P < 0.0001), number of comorbidities (P < 0.0001), and low-energy mechanism of injury (P = 0.009). AS patients were younger (P = 0.03) and had a higher risk of delayed fracture diagnosis (P = 0.012), but were otherwise similar to DISH patients. CONCLUSION: Patients with spine fractures and ASD are at high risk for complications and death and should be counseled accordingly. Multilevel posterior segmental instrumentation allows effective fracture healing. AS and DISH patients represent similar patient populations for the purpose of treatment and future research.

A comprehensive analysis with minimum 1-year follow-up of vertically unstable transforaminal sacral fractures treated with triangular osteosynthesis.

PURPOSE: To analyze the radiographic, clinical, and functional results of triangular osteosynthesis constructs for the treatment of vertically unstable comminuted transforaminal sacral fractures. SETTING: Level I trauma center. METHODS: During a 3-year period (July 1, 2003 to June 30, 2006), 58 patients with vertically unstable pelvic injuries were treated with triangular osteosynthesis fixation by a single surgeon at a single institution. Patients were followed-up prospectively as a single cohort, with institutional review board approval. Inclusion criteria for this study were skeletally mature patients with a vertically unstable pelvic ring injury associated with a comminuted transforaminal sacral fracture. Minimum follow-up, both clinically and radiographically, was 1 year. Computed tomography scan was performed on all patients at 6 months to assess healing of the fracture. If the fracture healed, the fixation was removed. Functional outcome was assessed using the Short Form 36, version 2, and short version of Musculoskeletal Functional Assessment questionnaires at 6 months (before fixation removal) and 12 months. RESULTS: Forty of 58 patients with an average age of 39 years were available for a minimum of 1-year follow-up. Wound complications requiring surgical debridement occurred in 5 patients (13%), all of whom had severe soft tissue wounds with internal degloving. Two patients required removal of infected fixation. Iatrogenic L5 nerve injury occurred in 5 patients (13%). Ten patients (25%) had a delayed union on computed tomography scans, and 3 patients had a nonunion as a result of residual fracture gap and incomplete reduction. Six patients (15%) were found to have pronounced tilting of the L5 vertebral body (scoliosis) and distraction of the L5/S1 facet joint ipsilateral to the fixation. This did not correct with removal of the fixation. Failure of the triangular osteosynthesis construct resulting in malunion occurred in 2 patients (5%). All but 2 patients (95%) complained of painful and prominent implants. Functional outcome scoring showed that patients continued to function below the population mean at 1 year but continued to improve, particularly with function and daily activity. Ninety-seven percent of patients returned to some form of work or schooling. CONCLUSIONS: Triangular osteosynthesis fixation is a reliable form of fixation that allows early full weight-bearing at 6 weeks while preventing loss of reduction in comminuted vertical shear transforaminal sacral fractures. For this study group, operative reduction was maintained until healing in 95% of patients. However, the 1-year follow-up shows a substantial rate of potential technical problems and complications. Of primary concern were the asymmetric L5 tilting with L5-S1 facet joint distraction and the need for a second surgery in all patients to remove painful fixation. Iatrogenic nerve injury occurred in 5 patients (13%) and is thought to arise secondary to fracture manipulation and reduction. We recommend selective use of this technique for comminuted transforaminal sacral fractures in situations only where reliable iliosacral or trans-sacral screw fixation is not obtainable.

Accuracy of reduction of ipsilateral femoral neck and shaft fractures--an analysis of various internal fixation strategies.

OBJECTIVES: Controversy surrounds the selection of the proper internal fixation device for treatment of ipsilateral fractures of the femoral neck and shaft. The purpose of this study was to review a large consecutive series of patients to learn more about the efficacy of various internal fixation strategies in maintaining an excellent reduction of both fractures. DESIGN: Retrospective multicenter. SETTING: Two level 1 trauma centers. PATIENTS/PARTICIPANTS: Between 1989 and 2006, 40 consecutive patients underwent internal fixation of an ipsilateral femoral neck and shaft fracture at 2 level 1 trauma centers. Thirty-seven of 40 patients (95%) with a mean age of 38 years (range, 18-73 years) had sufficient radiographs to assess accuracy of fracture reduction. INTERVENTION: Patients with displaced femoral neck fractures were typically treated with 2 separate devices and underwent formal open reduction of the femoral neck. Patients with nondisplaced neck fractures were treated with closed reduction and fixation with either 1 or 2 devices based on surgeon preference. The femoral neck fractures were displaced in 21 patients and nondisplaced in 16 patients. Nine fractures were addressed with a single implant and 28 with 2 separate devices. MAIN OUTCOME MEASUREMENTS: Radiographs were reviewed to evaluate the quality of reduction of both fractures. Clinical follow-up of 12 months or greater was available on 16 patients with a mean of 34.4 months (range, 12-112 months). RESULTS: Thirty-six of 37 patients (97%) obtained or maintained excellent femoral neck reductions. The only poor neck reduction occurred in the case of a displaced femoral neck-shaft fracture treated with a single cephalomedullary implant. Thirty-five excellent (95%) and 2 poor shaft reductions were obtained. Both shaft malreductions occurred in comminuted shaft fracture patterns in which a single cephalomedullary device was used for both fractures. Performing internal fixation of both fractures with a single cephalomedullary device led to a significantly higher rate of fracture malreduction of one of the fractures (3 of 9) as compared with a 2-device strategy (0 of 28) (P = 0.01). CONCLUSIONS: Open reduction and internal fixation of a displaced femoral neck fracture followed by retrograde nailing of the femoral shaft allowed accurate reduction and uneventful union of both fractures in most patients. The use of a cephalomedullary device to address both fractures simultaneously led to a significantly higher rate of malreduction of one of the fractures.
