Isolated thoracic and lumbar transverse process fractures: Do they need spine surgeon evaluation? a high volume level I trauma center experience with cost analysis

BackgroundTransverse process fractures (TPF) of the thoracic and lumbar spine have become increasingly identified due to CT imaging. Spine service consultation is common for further evaluation and management. There are several studies that demonstrate no difference in clinical outcome with or without spine service intervention. However, no study to our knowledge provides an additional cost analysis. We hypothesize that isolated thoracolumbar TPF are stable injuries. Furthermore, spine service consultation and evaluation results in increased health care costs. MethodsPatients were identified using trauma registry data at Saint Louis University (SLU) from January 2012 to August 2018. Chart and imaging review was performed to determine if additional spine fractures were identified by the spine team which were not included in the initial radiology report. TPF associated with other spinal injuries were defined as one or more thoracic and/or lumbar TPF in addition to any other acute fracture or dislocation in the cervical, thoracic, or lumbar spine. A separate cost analysis with institution-specific charges was also performed. ResultsSix hundred eighty-two patients with TPF from January 2012 to August 2018 were identified. Two hundred twenty-eight patients met the criteria to be included in this study. Additional spinal pathology that was not included in the initial radiology report was identified in 5 (2.19%) patients, none of which required surgical intervention. Cost analysis demonstrated additional costs associated with spine service intervention totaled $1,725,360.28. Average cost per patient in our cohort summed to $2,529.85 ConclusionsThese data support that isolated TPF of the thoracic and lumbar spine are stable injuries that likely do not require spine service intervention and in fact may represent unnecessary financial burden. Foregoing unnecessary consultation can alleviate time constraints within spine service practices and reduce health care costs by eliminating costly extraneous interventions from the patient's care.

Case Report-Traumatic L5-S1 Instability: Are Upright Radiographs Potentially Dangerous?

Traumatic lumbosacral instability is a rare but potentially devastating injury. These injuries are frequently associated with neurologic injury and often result in long-term disability. Despite their severity, radiographic findings can be subtle, and multiple reports exist in which these injuries were not recognized on initial imaging. Transverse process fractures, high-energy mechanisms, and other injury features have been suggested as indications for advanced imaging, which has a high degree of sensitivity in detecting unstable injuries. A 21-year-old man presented to our level I trauma center after being ejected in a rollover motor vehicle collision. He sustained multiple injuries, including multiple lumbar transverse process fractures and a unilateral superior articular facet fracture of S1. Initial supine computed tomography (CT) images showed no displacement of the fracture and no listhesis or instability. Subsequent upright imaging in a brace, however, demonstrated significant displacement of the fracture with dislocation of the contralateral L5-S1 facet joint and significant anterolisthesis. The patient underwent open posterior reduction and stabilization of L4-S1 followed by L5-S1 anterior lumbar interbody fusion. The patient demonstrated excellent alignment on postoperative imaging. At 3 months postoperatively, he had returned to work, was ambulating without assistance, and reported minimal back discomfort and no lower extremity pain, numbness, or weakness. This case serves as a warning that supine CT imaging alone may not be sufficient to rule out unstable lumbar spine injuries, such as traumatic L5-S1 instability, and that upright radiographs in these potentially unstable injuries may represent a hazard to patients. Fractures involving the pedicle, pars, or facet joints as well as multiple transverse process fractures and/or a high-energy mechanism of injury should all raise suspicion of instability and warrant additional imaging. This article provides guidance on approaching treatment for patients with potential traumatic lumbosacral instability.

The injury patterns, management and outcomes of retroperitoneal haemorrhage caused by lumbar arterial bleeding at a Level-1 Trauma Centre: A 10-year retrospective review

PurposeHaemorrhagic shock remains a leading preventable cause of death amongst trauma patients. Failure to identify retroperitoneal haemorrhage (RPH) can lead to irreversible haemorrhagic shock. The arteries of the middle retroperitoneal region (i.e., the 1st to 4th lumbar arteries) are complicit in haemorrhage into the retroperitoneal space. However, predictive injury patterns and subsequent management implications of haemorrhage secondary to bleeding of these arteries is lacking. Materials and methodsWe performed a retrospective cohort study of patients diagnosed with retroperitoneal haemorrhage who presented to our Level-1 Trauma Centre (2009–2019). We described the associated injuries, management and outcomes relating to haemorrhage of lumbar arteries (L1–4) from this cohort to assess risk and management priorities in non-cavitary haemorrhage compared to RPH due to other causes. ResultsHaemorrhage of the lumbar arteries (LA) is associated with a higher proportion of lumbar transverse process (TP) fractures. Bleeding from branches of these vessels is associated with lower systolic blood pressure, increased incidence of massive transfusion, higher shock index, and a higher Injury Severity Score (ISS). A higher proportion of patients in the LA group underwent angioembolisation when compared to other causes of RPH. ConclusionThis study highlights the injury patterns, particularly TP fractures, in the prediction, early detection and management of haemorrhage from the lumbar arteries (L1–4). Compared to other causes of RPH, bleeding of the LA responds to early, aggressive haemorrhage control through angioembolisation. These injuries are likely best treated in Level-1 or Level-2 trauma facilities that are equipped with angioembolisation facilities or hybrid theatres to facilitate early identification and management of thoracolumbar bleeds.

The role of the plastic surgeon in wound repair after spinal surgery

BackgroundWound complications, including dehiscence and surgical site infections, following spinal surgery have the potential to be devastating both to the patient and to the hospital system. Complications can occur in a wide range of patients including diabetics, those of low or high BMI and those of old age. Obese patients and those with increased subcutaneous fat are at particularly high risk for wound complications, which may be mitigated through use of local flap reconstruction by a Plastic Surgeon. Case DescriptionA 28 year-old female with morbid obesity presents with multiple lumbar transverse process fractures and complex sacral and pelvic fractures requiring closed reduction and percutaneous fixation of the pelvic ring followed by posterior spinal fusion. The patient was closed tension-free by the neurosurgery team and ultimately dehisced requiring consultation and management by Plastic Surgery. OutcomeThe patient underwent debridement and reconstruction with a gluteus maximus myocutaneous flap advancement without complication. ConclusionsWound management after spinal surgery is a complex problem, which may be prophylaxed through early identification of high-risk patients and preoperative consultation of Plastic Surgery. Patients with increased thickness of subcutaneous fat are at particularly high risk for postoperative complications, including infection and dehiscence, secondary to increased tissue manipulation and necrosis.

Impact of contrast extravasation on computed tomography of the psoas major muscle in patients with blunt torso trauma.

The clinical significance of contrast extravasation (CE) on computed tomography (CT) of the psoas major muscle after blunt torso trauma and the optimal management of patients requiring transcatheter arterial embolization (TAE) of the lumbar artery have not been well elucidated. The aim of this study was to investigate the impact of CE on CT to determine the need for TAE of the lumbar artery. We examined a single-center retrospective cohort of blunt torso trauma patients who underwent contrast-enhanced CT from 2008 to 2017. Basic demographics and clinical data were obtained, including the number of lumbar transverse process fractures (LTPFs) and maximum psoas major muscle hematoma (PMMH) size and ratio. Maximum PMMH size was analyzed by measuring the cross-sectional area of hematoma size at the level of CE. Psoas major muscle hematoma size ratio was obtained by dividing maximum PMMH size by psoas major muscle size of the unaffected side at the same slice level. A total of 762 patients were included. One hundred seventeen patients had LTPFs and/or PMMH. Of 117 patients, 25 had CE on CT of the psoas major muscle and had significantly higher rates of older age and severe injury compared with those without CE. Of the 25 patients with CE, 13 required TAE of the lumbar artery. Patients who required TAE had a significantly higher number of LTPFs (4 vs. 2, p = 0.011) and higher PMMH size ratio (2.10 vs. 1.32, p = 0.016). Psoas major muscle hematoma size ratio revealed moderate accuracy (area under the receiver operating characteristic curve, 0.782). Approximately half of the blunt torso trauma patients with CE on CT of the psoas major muscle will require TAE of the lumbar artery. Higher number of LTPFs and larger PMMH size can be a predictor of the need for TAE of the lumbar artery among patients with CE on CT. Therapeutic/care management, level IV.

Utilization of mechanical diagnosis and therapy (MDT) for the treatment of lumbar pain in the presence of known lumbar transverse process fractures: a case study

Background: Spinal fractures are typically considered a contraindication to mechanical diagnosis and therapy (MDT).Objective and importance: The purpose of this case study is to illustrate how MDT was used safely and effectively to treat lumbar pain in a patient with multiple lumbar transverse process fractures.Clinical presentation: The subject was a 24-year-old female with left L2-5 transverse process fractures, sustained 10 weeks prior in a pedestrian versus motor vehicle accident.Intervention (and technique): After collaboration with her physiatrist, an MDT examination revealed a presentation consistent with the lumbar derangement syndrome.Conclusion: After three visits, utilizing patient generated forces with the extension principle of treatment, her pain, Oswestry disability index (ODI) score, and function all improved.

Pediatric isolated thoracic and/or lumbar transverse and spinous process fractures.

OBJECTIVE Isolated transverse and spinous process fractures (TPFx and SPFx) in the thoracic and/or lumbar region have been deemed clinically insignificant in the adult population. This same rule is often applied to the pediatric population; however, little evidence exists in this younger group. The goal of this study was to describe the clinical, radiographic, and long-term data on isolated TPFx and SPFx in an exclusively pediatric population. METHODS A retrospective chart review at Monroe Carell Jr. Children's Hospital at Vanderbilt University identified 82 pediatric patients with isolated TPFx and/or SPFx following a traumatic event between January 2000 and December 2013. Patient demographic information, presenting symptoms, radiographic characteristics, and follow-up data were collected. Follow-up was used to determine the outcome (presence of neurological deficits) of such injuries via complete physical examination and, when available, radiographic evidence. RESULTS In the 82 identified patients, the mean age was 15.5 ± 3.1 years (mean is expressed ± SD throughout), with 72 injuries (87.8%) resulting from a motor vehicle, motorcycle, or all-terrain vehicle accident. There was a mean of 1.7 ± 1.0 fractured vertebral levels involved and a mean of 1.8 ± 1.1 fractures was identified per patient. Seventy-one patients (86.6%) needed bedside pain control, 7 (8.5%) were prescribed a brace, and 4 patients (4.9%) received a collar. Physical therapy was recommended for 12 patients (14.6%). A total of 84.1% had follow-up, and the mean length of follow-up was 19 ± 37 months. No patients had true neurological deficits at presentation or follow-up as a result of their isolated fractures, whereas 95.1% had other associated system injuries. CONCLUSIONS These data shows that there is no appreciable long-term complication associated with isolated thoracic and/or lumbar TPFx and/or SPFx in an exclusively pediatric population. Because these fractures are, however, associated with high-energy blunt trauma, they often result in associated soft-tissue or other skeletal injury. All pediatric patients in the cohort benefited from conservative management and aggressive treatment of their comorbidities.

Significance of Computed Tomography Finding of Intra‐Abdominal Free Fluid Without Solid Organ Injury after Blunt Abdominal Trauma: Time for Laparotomy on Demand

Optimal management of patients with intra-abdominal free fluid found on computed tomography (CT) scan without solid organ injury remains controversial. The purpose of this study was to determine the significance of CT scan findings of free fluid in the management of blunt abdominal trauma patients who otherwise have no indications for laparotomy. During the 3-year study period, all patients presenting with blunt abdominal trauma who underwent abdominal CT examination were retrospectively reviewed. All hemodynamically stable patients who presented with abdominal free fluid without solid organ injury on CT scan were analyzed for radiological interpretation, clinical management, operative findings, and outcome. A total of 122 patients were included in the study, 91 % of whom were males. The mean age of the patients was 33 ± 12 years. A total of 34 patients underwent exploratory laparotomy, 31 of whom had therapeutic interventions. Small bowel injuries were found in 12 patients, large bowel injuries in ten, and mesenteric injuries in seven patients. One patient had combined small and large bowel injury, and one had traumatic gangrenous appendix. In the remaining three patients, laparotomy was non-therapeutic. A total of 36 patients had associated pelvic fractures and 33 had multiple lumbar transverse process fractures. Detection of intra-peritoneal fluid by CT scan is inaccurate for prediction of bowel injury or need for surgery. However, the correlation between CT scan findings and clinical course is important for optimal diagnosis of bowel and mesenteric injuries.

Non-spinal–associated injuries with lumbar transverse process fractures

Lumbar transverse process fractures (LTPFs) are often with concomitant non-spinal-associated injuries (NSAIs). The purpose of this study was to analyze the correlation between the NSAIs and the LTPFs of different segments, amount, and concomitant thoracolumbar/lumbar vertebral fractures. A total of 1,181 patients with LTPFs or thoracolumbar/lumbar vertebral fractures were chosen between September 2006 and June 2010. The patients were divided into three groups: thoracolumbar/lumbar vertebral fractures without LTPFs, with associated LTPFs, and isolated LTPFs (iLTPFs). The correlation of the NSAIs of different sites and the LTPFs of different segments, amount, and concomitant thoracolumbar/lumbar vertebral fractures were analyzed between and within groups by χ test and logistic regression analysis. The incidence of NSAIs with iLTPFs and aLTFP groups were significantly higher than that of vertebral fractures without LTPF group (55.73% and 64.49% vs. 21.32%, respectively, p = 0.000). However, the incidence was not significantly different between the iLTPFs and the aLTFP groups (p = 0.106). The results with NSAIs of different sites were almost the same. L5TPFs were a stronger risk factor to NSAIs (relative risk [RR] = 15.72; 95% confidence interval [CI], 4.47-55.37; p = 0.000) in the iLTPF group (RR = 21.92; 95% CI, 6.68-71.92; p = 0.000) and in the vertebral fractures with associated LTPF group (RR = 9.42; 95% CI, 1.19-74.72; p = 0.034). L5TPFs were also a very important risk factor for pelvic injuries (RR = 46.10; 95% CI, 22.40-94.88; p = 0.000); 65.1% in L5iTPFs were accompanied with Tile-C pelvic injuries, slightly higher than in L5aTPFs (46.7%). L4TPFs were a risk factor to abdominal injuries within iLTPFs (RR = 2.27; 95% CI, 1.23-4.20; p = 0.009). The incidence of NSAIs is very high in cases with LTPFs, particularly with L5TPFs. A detailed investigation should be performed to search for NSAIs once LTPFs are identified so that appropriate treatment can be initiated. Level III.

Repair of Transverse Process Fractures of Multiple Lumbar Vertebrae in an Adult Dairy Cow

To report lumbar vertebrae transverse process fracture repair using a narrow 3.5 mm limited contact dynamic compression plate (LC-DCP) in an adult dairy cow. Case report. A 3-year-old Holstein cow. Under general anesthesia, fractured left transverse processes of lumbar vertebrae 2-4 were repaired using internal fixation. A narrow 3.5 mm LC-DCP was contoured and secured to the spinous process and the transverse process of each fractured vertebra. Fractured transverse processes of the lumbar vertebrae were successfully repaired and the cow discharged 10 days after surgery. At 10 months after surgery, the cow was declared reserved champion at a regional show. A paramedian approach and muscle splitting can be used to repair multiple lumbar transverse process fractures using internal fixation with an excellent cosmetic outcome.

Risk Factors for Lumbosacral Plexus Palsy Related to Pelvic Fracture

A retrospective study. We assessed risk factors for lumbosacral plexus palsy related to pelvic fracture that can be evaluated during the acute injury phase with diagnostics such as computed tomography (CT). Many patients with pelvic fracture are in vital shock, with polytrauma and loss of consciousness, making an accurate neurologic examination very difficult in the emergency room. This study included 22 patients who had AO classification type B or C pelvic fractures. The 22 patients had 27 posterior osteoligamentary lesions. The average injury severity score (ISS) was 27.5 (range, 16-50). Age, sex, ISS, suicidal jump, longitudinal displacement, sacral transverse fracture, pubic fracture, lumbar transverse process fracture, type of pelvic fracture (AO), and type of sacral fracture (Denis) were examined for a correlation with the lumbosacral plexus palsy. Using coronal reconstruction CT, we considered a 10 mm or greater displacement at the sacrum or sacroiliac joint to be a longitudinal displacement. Transverse sacral fracture was diagnosed by sagittal reconstruction CT. Of the 22 patients, 5 (22.7%) had lumbosacral plexus palsy (8 of 27 pelvic fractures) detected during treatment. The incidence of lumbosacral plexus palsy was not related to age, sex, ISS. Incidence of palsy was significantly higher when the patient's affected side had longitudinal displacement. Patients who had made a suicidal jump or had a sacral transverse fracture also had a significantly higher risk for lumbosacral plexus palsy. Palsy was not related to the type of pelvic fracture (AO) or sacral fracture (Denis). In this study, longitudinal displacement of the pelvis, transverse sacral fracture, and trauma from a suicidal jump were risk factors for lumbosacral plexus palsy. These risk factors were helpful in our examination of patients who had severe pelvic fracture with loss of consciousness.

The middle layer of lumbar fascia can transmit tensile forces capable of fracturing the lumbar transverse processes: An experimental study

Background Transversus abdominis and its aponeurotic attachment to the lumbar transverse processes via the middle layer of lumbar fascia are of proposed clinical and biomechanical importance. Moderate traction on these structures (simulating submaximal contraction of transversus abdominis) is reported to influence segmental motion, but their tensile capacity is unknown and the effects of sudden, maximal traction on these attachments and the transverse processes are uncertain. Methods In 15 embalmed cadaver abdomens, the middle layer of lumbar fascia was isolated, gripped and rapid tension applied in either a lateral or posteroanterior direction (simulating forces that may produce avulsion and traumatic fractures). Peak forces prior to tissue failure were recorded and the gross effects of traction documented. Findings Lumbar transverse process fractures were produced in all specimens; by transverse traction in 50% of tests and posteroanterior force in 80%. In the remainder the middle layer of lumbar fascia was torn. Mean transverse and posteroanterior peak forces reached in the middle layer of lumbar fascia prior to failure were 82 N (range 20–190 N) and 47 N (range 25–70 N), respectively. Interpretation The middle layer of lumbar fascia can transmit substantial tensile forces to lumbar vertebrae, capable of transverse process fracture under experimental conditions. Tensile capacity is likely to be even greater in-vivo. This suggests tranversus abdominis and the middle layer of lumbar fascia can strongly influence vertebral motion, should be incorporated in biomechanical models of the spine and considered as potential contributors to transverse process fractures by avulsion.

Missed lumbar transverse process fractures in a high school football player

Objective: To discuss the case of a football player who had suffered a transverse process fracture of the lumbar spine that was overlooked on initial chiropractic and medical examination. Clinical Features: A 17-year-old male football player had been speared in the back by another player. He reported severe initial pain that caused him to fall to the ground, and there was a moderate degree of pain at the time of his chiropractic examination 1 week after injury. Intervention and Outcome: Initial chiropractic treatment consisted of spinal manipulation to the lumbar spine. Follow-up care consisted of lumbar spine radiographs that showed evidence of a lumbar transverse process fracture at 2 levels. The boy was referred to his medical doctor, who was not convinced of the presence of a fracture and returned him to play. A computed tomography scan was subsequently performed; this confirmed fractures of the transverse processes of L2 and L3. The patient was precluded from contact sports for 4 weeks. Chiropractic care 3 weeks after injury included physiotherapy and drop table mobilization to the sacroiliac joints. The patient returned to play 4 weeks after the injury. Conclusion: Transverse process fractures commonly occur secondary to blunt trauma in contact sports such as football. With high-force direct trauma, radiographs should be performed to rule out fracture before returning the athlete to play or commencing spinal manipulation.(J Manipulative Physiol Ther 2001;24:123-6)

Lumbar transverse process fractures — a sentinel marker of abdominal organ injuries

Fractures of lumbar vertebrae may be associated with abdominal organ injuries. Lumbar transverse process fractures are commonly thought of as minor injuries compared with body, pedicle and lamina fractures. To determine the significance of transverse process fractures as opposed to other lumbar vertebral fractures in relation to abdominal organ injury, a retrospective study was performed. One hundred and ninety-one patients with lumbar spine fractures were reviewed. One hundred and thirty-five (71%) of these had non-transverse process (NTP) fractures only (including vertebral body, pedicle, or spinous process fractures). Fourty-two patients (22%) had transverse process fractures only. Fourteen patients (7%) had both transverse process and NTP fractures. Twenty (48%) of the 42 patients with transverse process fractures had abdominal organ injuries identified. This was a significantly ( P<0.05) higher rate than for the patients with NTP fractures, eight of 135 (6%). Patients with transverse process fractures and abdominal organ injuries had a median injury severity score (ISS) of 29 compared with a median ISS of 17 for patients with NTP fractures and abdominal organ injuries. If a transverse process has been fractured, there is likely to have been very large forces involved in the incident. The data strongly suggest that lumbar transverse process fractures should not be thought of as minor injuries but regarded as a significant marker for abdominal organ injuries and should alert the doctor caring for the injured patient of the high probability of these injuries.
