EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024:10.1007/s00590-024-03915-9. [PMID: 38573380 DOI: 10.1007/s00590-024-03915-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 03/14/2024] [Indexed: 04/05/2024]
Abstract
PURPOSE To review surgical complications after fixation of stress-positive minimally displaced (< 1 cm) lateral compression type 1 (LC1) pelvic ring injuries. METHODS A retrospective study at a level one trauma center identified patients who received surgical fixation of isolated LC1 pelvic ring injuries. Surgical complications and additional procedures were reviewed. RESULTS Sixty patients were included. The median age was 61 years (Interquartile range 40-70), 65% (n = 39) were women, and 57% (n = 34) had high-energy mechanisms. Anterior-posterior, posterior-only, and anterior-only fixation constructs were used in 77% (n = 46), 15% (n = 9), and 8% (n = 5) of patients. Anterior fixation was performed with rami screw fixation in 82% (49/60), external fixation in 2% (1/60), and open reduction and plate fixation in 2% (1/60). There were 15 surgical complications in 23% (14/60), and 12 additional procedures in 17% (10/60). Complications included loss of reduction ≥ 1 cm (8%), symptomatic hematomas (8%), symptomatic backout of unicortical retrograde rami screws (5%), deep infection of the pelvic space after a retrograde rami screw (1.6%), and iatrogenic L5 nerve injury (1.6%). All losses of reduction involved geriatric females with distal rami fractures sustained in ground-level falls. Loss of reduction was found to be more likely in patients with low energy mechanisms (proportional difference (PD) 62%, 95% confidence interval (CI) 18% to 76%; p = 0.01) and 2 versus 1 posterior pelvic screws (PD 36%; CI 0.4% to 75%; p = 0.03). CONCLUSIONS Surgical complications and additional procedures routinely occurred after fixation of LC1 injuries. Patients should be appropriately counseled on the risks of surgical fixation of these controversial injuries. LEVEL OF EVIDENCE Diagnostic, Level III.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023:10.1007/s00590-023-03804-7. [PMID: 38104045 DOI: 10.1007/s00590-023-03804-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 11/25/2023] [Indexed: 12/19/2023]
Abstract
PURPOSE To compare the success rate of a trial of labor (TOL) in a cohort of patients with pelvic fractures, with and without internal fixation, in order to better counsel patients and avoid unnecessary cesarean section (CS). METHODS A retrospective review of 35 female patients with 28 pelvic ring, five acetabular, and two combined fractures that had subsequent pregnancy; 12 patients had operative fixation and 23 did not. Fracture classification, treatment, type of fixation, mode of deliveries, and reason for CS were documented. RESULTS The rate of vaginal delivery, unscheduled CS, and scheduled CS across all patients was 80.0% (n = 28), 14.3% (n = 5), and 5.7% (n = 2), respectively, which was similar to institutional rates of 87.0, 12.0, and 1.0%. A TOL was attempted in 91.4% (32/35) and successful in 87.5% (28/32). Patients who failed a TOL were more likely to have Tile B/C pelvic fractures (100.0 vs. 30.4%, observed difference (OD) 69.6%, 95% confidence interval (CI) 16.4, 86.3%; p = 0.01) and more pelvic displacement (6.0 vs. 1.5 mm, OD 4.0, CI 1.0, 18.0; p = 0.01). The fixation and control groups had no observed difference in successful TOL (72.7% vs. 95.2%, OD 22.5%, - 49.7%, 5.5%; p = 0.10). CONCLUSIONS A majority of women had successful vaginal deliveries after pelvic fractures, with or without fixation, suggesting that these patients should consider a TOL. LEVEL OF EVIDENCE Diagnostic Level III.

Abstract
INTRODUCTION The purpose of this study was to describe the practice of postmobilization radiography after lateral compression type 1 pelvis ring injury. We hypothesized that postmobilization radiographs would be more frequent over time and would not influence treatment. METHODS Displacement of pelvis ring injury on initial and final plain radiographs was measured. Frequency of postmobilization radiography was determined, and the impact on treatment and final radiographical outcome were assessed. RESULTS Of the 156 patients reviewed, 98 (62.8%) were women and mean age was 60.1 years. Thirty-three of 156 patients (21.2%) had a postmobilization radiograph. Over 5 years, radiographs increased to 67% of presenting patients. None of the patients who received postmobilization plain radiographs (n = 33) had any change in clinical plan afterward; all continued with nonsurgical care. Initial fracture characteristics and alignment were no different for patients with postmobilization radiographs. Final alignment was unchanged in nearly 70%. Overall, 74% of all nonsurgical patients experienced no change in alignment, with similar rates among the patients with postmobilization radiographs. DISCUSSION Patients with an lateral compression type 1 fracture demonstrated no changes in care after receiving postmobilization radiographs. However, the frequency of postmobilization radiographs increased over time, denoting opportunities to reduce costs and to improve efficiency and safety.

Abstract
OBJECTIVES To compare the early outcomes of patients with stress-positive minimally displaced lateral compression type 1 (LC1b) pelvic ring injuries managed with or without operative fixation. DESIGN Retrospective comparison study. SETTING Level 1 trauma center. PATIENTS/PARTICIPANTS Forty-three patients with LC1b injuries. INTERVENTION Operative versus nonoperative. MAIN OUTCOME MEASUREMENTS Discharge to subacute rehabilitation (SAR); 2- and 6-week pain visual analog score, opioid use, assistive device use, percentage of normal single assessment numerical evaluation, SAR status; fracture displacement; and complications. RESULTS The operative group did not differ in age, gender, body mass index, high-energy mechanism, dynamic displacement stress radiographs, complete sacral fractures, Denis sacral fracture classification, Nakatani rami fracture classification, follow-up length, or American Society of Anesthesiologists classification. The operative group was less likely to be using an assistive device at 6 weeks [observed difference (OD) -53.9%, 95% confidence interval (CI) -74.3% to -20.6%, OD/CI 1.00, P = 0.0005], less likely to remain in an SAR at 2 weeks (OD -27.5%, CI, -50.0% to -2.7%, OD/CI 0.58, P = 0.02), and had less fracture displacement at follow-up radiographs (OD -5.0 mm, CI, -9.2 to -1.0 mm, OD/CI 0.61, P = 0.02). There were no other differences in outcomes between treatment groups. Complications occurred in 29.6% (n = 8/27) of the operative group compared with 25.0% (n = 4/16) of the nonoperative group resulting in 7 and 1 additional procedures, respectively. CONCLUSIONS Operative treatment was associated with early benefits over nonoperative management, including shorter time using assistive devices, less SAR use, and less fracture displacement at follow-up. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Nonoperative management of minimally displaced lateral compression type 1 (LC1) injuries with comminuted rami fractures is associated with late displacement. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023:10.1007/s00590-023-03646-3. [PMID: 37542555 DOI: 10.1007/s00590-023-03646-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 07/11/2023] [Indexed: 08/07/2023]
Abstract
PURPOSE Rami comminution has been found to be predictive of lateral compression type 1 (LC1) injury instability on examination under anesthesia (EUA) and lateral stress radiographs (LSR). The purpose of this study was to evaluate how rami comminution and subsequent operative vs. nonoperative management impact the late displacement of these injuries. METHODS Retrospective review of a prospectively collected LC1 database was performed to identify all patients with minimally displaced LC1 injuries (< 1 cm) and follow-up radiographs over a four-year period (n = 125). Groups were separated based on the presence of rami comminution and subsequent management, including rami comminution/operative (n = 49), rami comminution/nonoperative (n = 54), and no comminution/nonoperative (control group, n = 22). The primary outcome was late fracture displacement, analyzed as both a continuous variable and as late displacement ≥ 5 mm. RESULTS As a continuous variable, late fracture displacement was lower in the comminuted rami/operative group as compared to the comminuted rami/nonoperative group (PD: -3.0 mm, CI: -4.8 to -1.6 mm, p = 0.0002) and statistically non-different from control. Late displacement ≥ 5 mm was significantly more prevalent in the comminuted rami/nonoperative group than in the comminuted rami/operative and no comminution/nonoperative groups (control)(PD: -33.9%, CI: -49.0% to -16.1%, p = 0.0002 and PD: -30.0%, CI: -48.2% to -6.5%, p = 0.02, respectively). CONCLUSION Late fracture displacement was greatest in the group with rami comminution/nonoperative management. Rami comminution, which has been previously associated with dynamic displacement on EUA and LSR, is also associated with a higher incidence of late displacement when managed nonoperatively. LEVEL OF EVIDENCE Level III, prognostic retrospective cohort study.

Abstract
OBJECTIVES To determine the incidence of patients with isolated pubic rami fractures on computed tomography scans who have dynamic instability secondary to occult lateral compression pelvic ring injuries. DESIGN Retrospective comparison study. SETTING Urban level 1 trauma center. PATIENTS/PARTICIPANTS This study included geriatric patients with isolated pubic rami fractures and inability to mobilize secondary to pain. INTERVENTION Lateral stress radiographs of pelvis to evaluate for ≥1 cm dynamic instability. MAIN OUTCOME MEASUREMENTS Physical therapy clearance, hospital length of stay, and discharge location. RESULTS A total of 19 patients were identified over 12 months. Patients were predominantly geriatric (median age: 75 years, interquartile range: 67 to 90), woman (11/19), with unilateral (17/19) comminuted distal rami fractures (12/19) sustained in ground-level falls (12/19). Dynamic instability was identified in 42% of patients (8/19). Magnetic resonance imaging, obtained in 6 of these patients, demonstrated occult posterior ring fractures in all cases. Patients with dynamic instability were more likely to have comminuted distal rami fractures (Nakatani type 1b) and a longer hospital length of stay. There was also a trend for these patients to be unable to clear physical therapy by discharge (63% (5/8) versus 36% (4/11)). The 90-day mortality rate of the cohort was 16% (3/19). CONCLUSIONS Patients presenting with seemingly isolated pubic rami fractures on radiographs and computed tomography scans who are unable to mobilize may have occult lateral compression injuries with dynamic instability.

Abstract
PURPOSE The purpose of this study was to review the practice of utilizing lateral stress radiographs (LSRs) to identify occult instability (≥ 10 mm of dynamic displacement on LSRs) of minimally displaced lateral compression type 1 (LC1) pelvic ring injuries and to evaluate for associations between instability and patient demographics, injury characteristics, and hospital course. METHODS A retrospective review of a prospective registry from 2018 to 2022 identified 151 patients with LC1 injuries. LSRs were obtained in 86.8% (131/151) of patients. Three (2.2%) patients were excluded for malrotation of LSRs, leaving 128 patients for analysis. RESULTS The median maximum dynamic displacement on LSRs was 12.2 mm (IQR: 5.9 to 17.3). Occult instability was present in 62.5% (80/128) of patients and was associated with older age (Median difference 11.0 years, 95% CI 3.0 to 20.0), Nakatani type 1 rami fractures (73.7% vs. 47.9%, p = 0.001), and rami fracture comminution (Proportional difference 58.7%, 95% CI 42.8 to 71.3%), but not gender, high-energy mechanism, bilateral rami fractures, Denis classification, sacral fracture completeness, or sacral comminution. Patients with occult instability took longer to ambulate 15 feet and clear physical therapy (PT), were more likely to be unable to clear PT by hospital day 3 or by time of discharge, had longer hospital stays, and were more likely to require rehabilitation facilities. CONCLUSION LSRs were obtained in a majority of patients. Occult instability was frequently present and associated with older age, comminuted distal pubic rami fractures, longer hospital stays, longer times to mobilize and clear PT, and an increased need for rehabilitation facilities.

Abstract
PURPOSE The purpose of this study was to compare patients with traumatic pelvic ring injuries sustained in road and mountain bicycling accidents to evaluate for differences in injury types and hospital courses. METHODS A retrospective review of 60 patients presenting with pelvic ring injuries after road (n = 46) and mountain (n = 14) bicycling accidents was performed to compare patient/injury characteristics and hospital course. RESULTS LC1 injuries were the most common pelvic ring injury (n = 31, 51.7%), 38.7% (n = 12) of which were considered unstable, followed by isolated iliac wing (n = 11, 18.3%), pubic rami (n = 6, 10.0%), and sacral fractures (n = 6, 10.0%). Hospital admission was required for 41 (68.3%) patients. The median hospital LOS was 4 days (IQR 2-9) and 12 (20%) patients received operative treatment. Patients in road versus mountain bicycling accidents were more likely to be older tobacco users and were similar in sex, body mass index, and injury severity score. Road bicycling resulted in more LC1 injuries (58.7% vs 28.6%, p = 0.04), while mountain bicycling resulted in more iliac wing fractures (42.9% vs. 10.9%, p = 0.01). Road cycling injuries required more days in the hospital to clear PT (median difference 2, CI 0-4, p = 0.04) and had longer hospital stays (median difference 2, CI 0-6, p = 0.02) but had no difference in the rate of admission, operative intervention, or discharge to rehabilitation facilities. CONCLUSION The majority of pelvic ring injuries from road and mountain bicycling accidents were LC1 injuries that were frequently unstable and often required hospital admission and operative fixation.
