Does operative treatment of geriatric pelvic ring injuries lead to a high risk of one-year mortality?

Early Outcomes of Operative Versus Nonoperative Management of Stress-Positive Minimally Displaced Lateral Compression Type 1 Pelvic Ring Injuries

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.

Comparison of the two surgery methods combined with accelerated rehabilitation in the treatment of lateral compression type 1 pelvic fractures in the elderly

BACKGROUND

Treating lateral compression type 1 (LC1) pelvic ring injuries in older patients is controversial. This study evaluated surgical treatments combined with ERAS for treating LC1 pelvic fractures in the elderly.

METHODS

In this retrospective study, patients who underwent surgery with INFIX (supra-acetabular spinal pedicle screws, and a subcutaneous connecting rod; the experimental group) or superior pubic ramus cannulated screw (the control group) fixation of LC1 pelvic fracture from January 2019 to January 2022 were reviewed. Injury radiography and computed tomography were performed to determine the Young-Burgess classification. All patients performed standardized early rehabilitation exercises after surgery and were followed up for > 12 months. After surgery, the Matta score and the visual analog scale (VAS) were evaluated, and the postoperative weight-bearing time and the length of stay (LOS) were recorded. The Barthel index and the Majeed score were evaluated at 4 months after surgery and at the last follow-up.

RESULTS

Fifty-three patients were included. Thirty-two patients included in the experimental group had a mean age of 75.0 ± 6.2 (range, 66-86) years, and the other 21 patients in the control group had a mean age of 74.6 ± 4.6 (range, 68-83) years. The mean follow-up time was 13.1 ± 1.6 (range, 12-18) months in the experimental group and 13.4 ± 1.3 (range, 12-16) months in the control group. There were no significant differences in follow-up time between the groups (P > 0.05). The mean VAS score, time to weight-bearing, and LOS were 2.0 ± 0.7 (range, 1-3), 1.1 ± 0.3 (range, 1-2) d, and 5.8 ± 0.9 (range, 4-7) d in the experimental group and 2.3 ± 1.2 (range, 1-5), 2.5 ± 1.6 (range, 1-7) d, and 6.1 ± 1.6 (range, 5-11) d in the control group, respectively. Between the two groups, there was a significant difference in the postoperative time to weight-bearing (P < 0.05), while there was no significant difference in the LOS (P > 0.05). No bedrest-related complications occurred in either group. The Matta score was 90.6% in the experimental group and 90.4% in the control group (P > 0.05). At the 4-months follow-up, the experimental group had a better Barthel index and Majeed score compared with the control group, which were 86.1 ± 6.2 (range, 70-95) vs. 81.2 ± 4.1 (range, 75-90) and 86.3 ± 3.3 (range, 78-91) vs. 80.3 ± 3.9 (range, 76-86), respectively. The experimental group had better early rehabilitation effect than the control group. There was no significant difference in Barthel index and Majeed score between the two groups at the last follow-up (P > 0.05).

CONCLUSION

Both INFIX and intramedullary superior pubic ramus cannulated screws can successfully treat LC1 pelvic fractures and reduce bed rest complications among older patients.

Pelvic ring injuries after alpine ski and snowboard accidents

PURPOSE

The purpose of this study was to analyze the patient/injury characteristics and associated hospital course of patients sustaining traumatic pelvic ring injuries after alpine ski and snowboard accidents at a level one trauma center in the Rocky Mountain region.

METHODS

Patient/injury characteristics were obtained from patients presenting with pelvic ring injuries after alpine ski (n = 55) and snowboard (n = 9) accidents. Characteristics and outcomes analyzed included mechanism of injury, pelvic ring classification (Young-Burgess and Tile), hospital admission, physical therapy (PT) clearance, ambulation, length of stay, inpatient morphine milligram equivalents (MME), and discharges to rehabilitation facility.

RESULTS

Snowboarders were more often younger, male, tobacco/substance users, and more likely to be injured by a fall from height than skiers. There were no differences in injury classification or hospital course outcomes between alpine sports. Most common injuries included lateral compression type 1 (LC1) injuries (37.5%), isolated pubic ramus fractures (31.3%), and isolated iliac wing fractures (15.6%). LC1 injuries were unstable in 50% of cases and associated with increased admissions (proportional difference: 47.5%, CI: 23.8-64.5%, p = 0.0002), longer time to PT clearance (median difference(MD): 1.0 day, CI: 0-2.0, p = 0.03), longer LOS (MD: 2.0, CI: 0-2.0, p = 0.02), and increased inpatient MMEs (MD: 197.9 MME, CI: 30.0-420.0, p = 0.02), as compared to other pelvic ring injuries.

CONCLUSION

The majority of pelvic ring injuries from alpine ski and snowboard accidents were LC1 injuries, half of which were unstable, resulting in longer hospital stays, time to PT clearance/ambulation, and opioid use.

Unstable minimally displaced lateral compression type 1 (LC1) pelvic ring injuries have a similar hospital course as intertrochanteric femur fractures

INTRODUCTION

The purpose of this study was to evaluate how the hospital course of minimally displaced LC1 fractures, with and without occult instability, compares with that of intertrochanteric femur fractures.

PATIENTS AND METHODS

Retrospective comparative cohort analysis at an urban level one trauma center of 40 consecutive patients with an isolated LC1 pelvic ring injury and 40 age/sex matched patients with an isolated intertrochanteric femur fracture was performed. Medical records and radiographs were reviewed for patient and injury characteristics, including demographics, displacement, time to surgery, ambulation, physical therapy (PT) clearance, hospital length of stay (LOS), and inpatient morphine milligram equivalents (MME).

RESULTS

The LC1 pelvic ring injury group included 26 (65%) patients with ≥ 10 mm of displacement on lateral stress radiographs. The unstable LC1 group, compared to the stable LC1 group, had a greater LOS (median difference (MD): 2 days, 95% confidence interval (CI): 1 to 4, p = 0.0004), longer time to ambulate 15 feet (MD: 1 day, CI: 1 to 2, p = 0.0002), longer time to clear PT (MD: 2 days, CI: 1 to 3, p = 0.0003), and more inpatient MMEs (MD: 386 MME, CI: 225.8 to 546.7, p = 0.0002). The unstable LC1 and intertrochanteric fracture groups had no detectable differences in LOS (p = 0.24), days to ambulate 15 feet (p = 0.46), days to clear PT (p = 0.95), and inpatient MMEs (p = 0.06).

CONCLUSION

Patients with minimally displaced unstable LC1 injuries had worse hospital courses than stable LC1 injuries and similar hospital courses as intertrochanteric femur fractures. These findings emphasize the associated morbidity of unstable LC1 injuries.
