Background: The study aimed to assess the effectiveness of antibiotic treatment for spondylodiscitis, its failure rates, and the need for surgical intervention. Methods: This is a retrospective study of patients who presented with spontaneous deep spinal infections and spondylodiscitis between 2011 and 2013. Clinical, bacteriologic, and radiographic data during hospitalization were analyzed. Results: A total of 16 patients presented with deep spinal infections during the study period; 15 of them presented with spontaneous pyogenic spondylodiscitis, and 1 presented with epidural abscess. Median age was 68 years (range, 50–80 years), and 6 (38%) were healthy young laborers. None of the patients were immunocompromised. On admission all patients presented with pain, there was fever in 3 patients (19%), and there was elevated blood C-reactive protein, white blood cell count and erythrocyte sedimentation rate, with a mean of 147 ± 83.1 mg/L, 11.65 ± 5.6 × 103/μL, 93.6 ± 35.1 mm/h, respectively. A total of 15 patients (94%) developed infections that were refractory to appropriate culture-specific intravenous antibiotic treatment (mean, 10.2 days); 8 patients (50%) deteriorated neurologically and required wide surgical decompression. Complications included widespread epidural free gas in 2 patients (12%), multiple bilateral psoas abscesses in 2 patients (12%), kyphotic segmental instability in 4 patients (25%), and inferior vena cava septic thrombi in 1 patient (6%). A total of 3 patients (19%) died within 6 months; 7 of 13 surviving patients still had residual neurologic deficits at the 6-month follow-up. Conclusions: Spondylodiscitis may be resistant to antibiotic treatment and may evolve into epidural abscess via extension of the infection and pus into the spinal canal, necessitating repetitive surgical treatment due to neurologic and clinical deterioration, and expansion of the persistent infection with a mass effect. Increased vigilance for this condition and its misleading initial presentations is warranted.

BACKGROUND: Semi-rigid cervical collars (SRCC) are routinely applied to victims of explosions as part of the pre-hospital trauma protocols. Previous studies have shown that the use of SRCC in penetrating injuries is not justified due to the scarcity of unstable cervical spine injuries and the risk of obscuring other neck injuries. Explosion can inflict injuries by fragments penetration, blast injury, blunt force and burns. The study purpose was to determine the occurrence of cervical spine instability without irreversible neurological deficit and other potentially life threatening non-skeletal neck injuries among victims of explosions. The potential benefits and risks of SRCC application in explosion related injuries (ERI) was Evaluated. METHODS: a retrospective cohort study of all explosions civilian victims admitted to Israeli hospitals during the years 1998-2010. Data collection was based on the Israeli national trauma registry and the hospital records, and included demographic, clinical and radiological details of all patients with documented cervical spine injuries. RESULTS: the cohort included 2,267 patients. All of them were secondary to terrorist attacks. SRCC was applied to all the patients at the scene. Nineteen patients (0.83%) had cervical spine fractures. Nine patients (0.088%) had unstable cervical spine injury. All but one had irreversible neurological deficit on admission. 151 patients (6.6%) had potentially life threatening penetrating non-skeletal neck injuries. CONCLUSIONS: Unstable cervical spine injuries secondary to explosion are extremely rare. The majority of unstable cervical spine fractures were secondary to penetrating injuries, with irreversible neurological deficits on admission. The application of SRCC did not seem to be of any benefit in these patients and might pose a risk of obscuring other neck injuries. We recommend that SRCC will not be used in the pre-hospital management of victims of explosions. LEVEL OF EVIDENCE: Retrospective observational study, level III. Language: en

Purpose: Traditional maneuvers aim to decrease retroperitoneal bleeding in hemodynamically unstable multi-trauma patients with unstable pelvic fractures, are reportedly successful in approximately only 50%. The life-saving effect of extra-peritoneal pressure packing (EPPP) is based on direct compression and control of both venous and arterial retroperitoneal bleeders. This study describes the safety and efficacy of emergent EPPP employment, as a stand-alone surgical treatment, that is, carried out without external pelvic fixation or emergent angiography. Materials and Methods: A retrospective chart review of all hemodynamic unstable, multi-trauma patients with mechanically unstable pelvic fractures treated by the EPPP technique at our medical center between the years 2005 and 2011. Survival rates, clinical, and physiological outcomes were followed prospectively. Results: Twenty-five of the 181 pelvic fracture patients had biomechanically unstable fractures that required surgical fixation. Fourteen of those 25 patients had deteriorating hemodynamic instability from massive pelvic bleeding which was resistant to resuscitation, and they underwent EPPP, as a stand-alone treatment. The procedure successfully achieved hemodynamic stability in all 14 patients and obviated the early mortality associated with massive pelvic bleeding. Three of these patients eventually succumbed to their multiple injuries. Conclusion: Implementation of EPPP improved all measured physiological outcome parameters and survival rates of hemodynamically unstable multi-trauma patients with unstable pelvic fractures in our trauma center. It provided the unique advantage of directly compressing the life-threatening retroperitoneal bleeders by applying direct pressure and causing a tamponade effect to stanch venous and arterial pelvic blood flow and obviate the early mortality associated with massive pelvic bleeding.

AIM: To investigate the potential distinct risk factors associated with trochanteric and cervical hip fractures. METHODS: Elderly patients aged 65 years and older (n = 1161) were admitted to the orthopedic department with hip fractures during the years 2006-2011. Demographic and clinical data, as well as routine blood tests, were retrieved from the patient electronic medical records. RESULTS: Approximately 58% of patients had trochanteric fractures and 42% had cervical fractures. Women were more likely to have trochanteric fractures than men (P = 0.002). Female sex, frailty, falls, diabetes and subnormal calcium, as well as subnormal hemoglobin levels, were significant risk factors for trochanteric fractures (OR 1.39, P = 0.0202, OR 1.36, P = 0.0166, OR 1.49, P = 0.0015, OR 1.33, P = 0.0343, OR 0.68, P = 0.0054, OR 0.70, P = 0.0036, respectively). Patients with Parkinson's disease were at a lower risk for trochanteric fractures (OR 0.6, P = 0.007). CONCLUSION: As there are some differences between risk factors for trochanteric and cervical hip fractures, there is a need for further studies in order to understand the etiology of fractures and to be able to carry out effective preventive efforts.

Background: Familial dysautonomia is a hereditary multisystemic disease primarily affecting people of Ashkenazi Jewish descent. Musculoskeletal problems are related to gait disorders, spinal deformities, foot deformities, fractures, and arthropathies. Methods: The charts and radiographs of 136 patients who ranged in age from three months to forty-six years (mean, sixteen years) were reviewed. Sixty-four patients were available for follow-up examination. Results: Spinal deformity was the most common orthopaedic problem and was diagnosed in seventy-eight patients starting at the age of four years, with a prevalence of 86 percent (forty-eight of fifty-six) by the age of fifteen years. Forty-one (53 percent) of the seventy-eight patients had scoliosis only, thirty-four (44 percent) had kyphoscoliosis, and three (4 percent) had kyphosis only. Bracing was accompanied by emotional, pulmonary, and skin problems, leading to a high rate of noncompliance and progression of the curve. Twenty-four patients had an operation at a mean age of thirteen years (range, five to eighteen years): twenty patients had posterior spinal arthrodesis, and four had combined anterior and posterior arthrodesis. Fifteen patients had a total of nineteen complications, of which seven were systemic and twelve were related to the spinal fixation. Eight patients had revision surgery. At the time of the surgery, scoliosis was corrected from a mean of 55 degrees to a mean of 35 degrees and kyphosis was corrected from a mean of 69 degrees to a mean of 61 degrees. After a mean duration of follow-up of sixty-five months, scoliosis measured 49 degrees (range, 18 to 62 degrees) and kyphosis measured 67 degrees (range, 30 to 115 degrees). Postoperative progression of the deformity was caused by failure of the instrumentation or progression in unfused segments. Walking was delayed in 72 percent (ninety-four) of the 130 patients who were of walking age. All sixty-four of the patients who were examined had an ataxic gait. Foot deformities were found in sixteen patients, six of whom were treated surgically. Two patients had Charcot joints. Fifty-five patients sustained at least one fracture before skeletal maturity, with a mean of 1.5 fractures per patient. All but one of the fractures was treated nonoperatively, and fracture-healing was often accompanied by profuse callus formation. Conclusions: Spinal deformity is common in patients with familial dysautonomia. Bracing is of questionable benefit, and surgical intervention should be considered once curve progression is well documented. Arthrodesis should be extended as far proximally as possible to prevent junctional kyphosis. Swelling and warmth in a limb should raise suspicion of an undiagnosed fracture.

Study design A retrospective clinical study of patients with vertebral osteomyelitis of the lumbar spine necessitating surgical treatment. All patients underwent sequential (same-day) or simultaneous anterior decompression and posterior stabilization of the involved vertebrae. Objective To evaluate the efficacy and clinical out-come of sequential or simultaneous anterior and posterior surgical approaches in the management of vertebral osteomyelitis of the lumbar spine. Summary of background data Anterior approach alone and staged anterior decompression and posterior stabilization have been advocated as the surgical treatment methods of choice for patients with vertebral osteomyelitis of the lumbar spine. The drawbacks of the latter management plan are the necessity to use external support or the delayed patient mobilization and the need for additional anesthesia and surgical trauma. Sequential (same-day) anterior and posterior approaches are used regularly in the surgical management of scoliosis and other spinal deformities. It would appear advantageous to also use the same strategy (i.e., combined same-day double approaches) in the management of vertebral osteomyelitis of the lumbar spine. Methods Ten consecutive patients who had a diagnosis of vertebral osteomyelitis of the lumbar spine underwent combined (same-day) anterior and posterior approaches either in a sequential or simultaneous manner. Indications for surgery included neurologic deficit, abscess formation, instability with localized kyphosis formation, and failure of nonoperative treatment. Patients were evaluated clinically and radiographically after surgery. Results All 10 patients had uneventful surgery. Only one patient required a second surgical procedure because of expulsion of the anterior bone graft and pull-out of instrumentation. All patients were mobilized within the 2 days immediately after surgery. At the mean follow-up examination 30 months after surgery, all patients had regained their motor function and prior ambulatory status. Conclusions Patients with lumbar osteomyelitis necessitating surgery can undergo combined, same-day surgery either in a sequential or simultaneous manner. This is a safe and efficient way to control the infection and stabilize the affected segments, allowing for early mobilization of these sick elderly patients.

Twenty-nine patients with tibial diaphyseal fractures had external fixators applied to treat their initial fractures and underwent nonreamed solid core nailing for nonunion (>22 weeks). Fifteen Alta, 11 Lottes, and 3 Rush nails were used. The original fracture grades were: 1 closed, 1 grade I, 7 grade II, 3 grade IIIA, and 17 grade IIIB. The duration of nonunion was 51 weeks (average: 22 to 173). The average duration of external fixation was 19 weeks (range: 9 to 47). The average interval from fixator removal to nail was 32 weeks (range: 0 to 156). Twenty-eight patients were seen at >12 months' follow up (average: 35; range: 10 to 58) and completion of treatment. Twenty-seven patients' fractures united at an average of 14 weeks (range: 6 to 40). One patient required a reamed exchange nailing at 39 weeks and united 58 weeks post-exchange nailing. One patient had a persistent asymptomatic nonunion. One patient developed a stress fracture 49 months post nail requiring an exchange nailing. Eleven fractures had a prenail deformity of 10° or more; 9 were corrected. Eight patients had pre-nail wound and five had pre-nail pin tract infections. Except for two cases, all of these infections were treated successfully with surgical debridement and/or antibiotics prior to nail insertion. Two patients had their nail inserted through active infections that could not be controlled with an unstable fracture. One patient healed uneventfully in 6 weeks. One required two subsequent debridements. There were no other infections. The authors conclude that nonreamed solid core nailing is an acceptable treatment for tibial diaphyseal nonunions following external fixation.

The efficacy of nonreamed nailing as the treatment of choice of unstable blunt tibial diaphyseal fractures was studied. From March 1, 1990, through August 31, 1991, 72 patients with 74 fractures that required fixation were treated. One patient died and six were lost to follow-up, leaving 65 patients with 67 fractures. Follow-up averaged 21 months (range 5-43). Fisher's exact and logistic regression analyses were used to compare grades of open fractures, comminution as classified by Winquist, and dynamic and static nailings. The failure rates of 51 titanium and 16 stainless steel nails were compared. Times to union were compared by the log rank statistic method. The average time to union was 32 weeks with 26 (39%) additional operations required to achieve union; 13 dynamizations (12 successful), 12 exchange nailings (11 successful), and one plate and bone graft. The rate of reconstructive procedures to achieve union was a more sensitive indicator of difficulties achieving union than was time to union. Reoperation rates were 33% for closed or grade I and II fractures compared with 46% for grade III fractures (NS). Among closed grade I and II static versus dynamic nailing, times to union were 36 versus 25 weeks (p < 0.01), and the reoperation rates were 44% versus 13% (p < 0.04). Winquist I and II fractures required a 24% reoperation rate versus 53% for grade III and IV and segmental fractures (p < 0.01). Static locked fractures required a 48% reoperation rate versus 12% for dynamic locked fractures (p < 0.01). A logistic regression analysis demonstrated that locking mode was the most important factor in determining reoperation rates. Fifteen additional reoperations for infection, broken or painful implants, or to remodel bones that united with an incomplete circumference of cortex were performed. With an additional 12 elective nail removals, the total reoperations numbered 53 (79%). Titanium alloy nails had a 2% failure rate versus 25% for stainless steel nails (p < 0.01). Two of 28 (7%) grade III fractures became infected. All fractures united within 10 degrees of normal alignment and 1 cm of length. Nine (13%) united with an incomplete cortical circumference, refractory to dynamization and full weight bearing. Thirteen of the 58 (22%) fractures available for an evaluation of ankle motion were symptomatic, with < 10 degrees of dorsiflexion.(ABSTRACT TRUNCATED AT 400 WORDS)

Case: Few cases of spinal epidural abscess involving an extradural abscess with an intradural extension have been reported. A unique complication with extension of pus from the epidural space through multiple perforations into the dura is described. Due to a proximal meningeal inflammatory reaction, which served as a proximal plug, no cerebrospinal fluid leak was encountered. Conclusion: Intradural extension of pus through multiple dural perforations is a rare complication of spinal epidural abscess and a treatment challenge. Early diagnosis enabling prompt surgical decompression, along with subsequent aggressive debridements and prolonged intravenous antibiotic treatment, can lead to a favorable outcome.
