Rate of skin and nerve complications as a result of cutaneous traction with modern foam boots.

INTRODUCTION: Cutaneous traction is used to temporize lower extremity fractures and relies on friction between the skin and surrounding material to apply a longitudinal force. This circumferential compressive force can lead to pressure sores, skin sloughing, or compressive neuropathies. These complications have been reported in up to 11% of patients when the cutaneous traction relies on adhesive tapes, plaster, and rubber bandages being in immediate contact with the skin. The rates of these complications are not well documented when using modern foam boots. METHODS: A retrospective chart review was performed on all orthopedic trauma patients who suffered pelvic or lower extremity injuries between March 1st, 2020 and April 30th, 2021 at a single Level-1 trauma center. We included all patients with femoral fractures, axially unstable pelvic ring and/or acetabular fractures, and unstable hip dislocations temporized with the use of cutaneous traction. All patients had intact skin and lower extremity nerve function prior to application. RESULTS: There were 138 patients identified with 141 lower extremities. The average patient age was 50.7 (6-100) years. Mean traction weight of 9.8 (5-20) pounds. Average traction duration was 20.9 (2.3-243.5) hours. At the time of traction removal, there was 1 (0.7%) new skin wound and 0 nerve palsies. The new skin wound was a stage one heel pressure sore and did not require further treatment. CONCLUSION: Cutaneous traction with a modern foam boot was found to have a skin complication rate of 0.7% and a nerve palsy complication rate of 0% for an overall complication rate of 0.7%, which has not been previously established and is lower than historically reported complication rates of 11% when utilizing adhesive and plaster directly on skin. Foam boot Cutaneous traction may be considered a safe option for traction placement.

Traumatic spinal injury patterns of on vs. off-road motorcycle crashes.

OBJECTIVE: Two wheel motorized vehicles used in both street transportation and recreation are a common cause of severe injury in the United States (US). To date, there has been limited data describing the spinal injury patterns among these motorcycle injury patients in the US. The goal of this study is to characterize and compare differences in specific injury patterns of patients sustaining traumatic spinal injuries after motocross (off-road) and street bike (on-road) collisions in the southwestern US at a Level I Trauma Center. METHODS: Trauma registry data was queried for patients sustaining a spinal injury after motorcycle collision from 2010 to 2019 at a single Level I Trauma Center. Computed tomography (CT) scan and magnetic imaging resonance imaging (MRI) reports from initial trauma evaluation were reviewed and data was manually obtained regarding injury morphology and location. RESULTS: A total of 1798 injuries were identified in 549 patients who sustained a motorcycle collision, specifically 67 off-road and 482 on-road motorcycle patients. Off-road motorcycle patients were found to be significantly younger (34.75 vs. 42.66, p = 0.00015). A total of 46.2% of the off-road injuries were determined to be from compression mechanisms, compared to 32.9% in the on-road cohort (p = 0.0027). The on-road cohort was more likely to have an injury classified as insignificant, such as transverse and spinous process fractures (60.1% vs. 42.5%, p = 00.25). There was no significant difference in regards to junctional, mobile, and semirigid spine segments between the two cohorts. CONCLUSIONS: Different fracture patterns were seen between the off-road and on-road motorcycle cohorts. Off road motorcyclists experienced significantly more compression and translational injuries, while on road motorcyclists experienced more frequent insignificant injury patterns. Data on the different fracture patterns may help professionals develop safety equipment for motorcyclists.

One-year postoperative knee pain in patients with semi-extended tibial nailing versus control group.

The purpose of this study was to determine whether patients with a tibia fracture who were treated with an intramedullary nail using a semi-extended, extra-articular, parapatellar approach had anterior knee pain at a higher than acceptable incidence compared with control patients. Eighteen patients with OTA type 42 A-C tibia fractures nailed using this approach were compared with an uninjured control group (n = 22). Lysholm Knee Score questionnaires were given to all participants and compared between groups. Fracture patients completed the LKS at 6 months and 1 year postoperatively. Additional data collected included age, sex, mechanism of injury, OTA classification, Gustilo/Anderson and Tscherne classification, nail-apex distance, complications, weight-bearing status, additional fixation needed, and postoperative procedures. Mean age and demographics were similar between the fracture and control group: 42.9 vs 47.9 years, respectively, (P=.36) and 11 vs 9 men, respectively (P=.11). Lysholm Knee Scores among the subgroups (age, sex, medial vs lateral parapatellar approach, soft-tissue status, and nail-apex distance) showed no statistically significant differences (P>05 for all comparisons). Mean nail-apex distance was -16.3 mm. Mean LKS score 1-year postoperatively was 87.3 (range, 59-100) in the fracture group and 89.7 (range, 23-100) in the control group (P=.69). At 1-year postoperatively, patients in the fracture group did not have increased anterior knee pain compared with the control group.
