Case: A 71-year-old man with a history of C5-7 anterior cervical discectomy and fusion (ACDF) sustained a C7 spinous process fracture after falling from a ladder. He was initially managed nonoperatively but developed anterolisthesis and kyphosis at C7-T1 with left hand weakness over the course of 11 days. Surgical treatment included spinous process wiring and C5-T3 posterior fusion.

- This study evaluated modified Radiographic Union Scale for Tibia (mRUST) scores over time in patients with distal femur fractures treated with intramedullary nails, to identify factors influencing healing and possible reoperation.
- Conducted in ten Level I Trauma Centers, the research included 155 fractures from 152 patients, focusing on mRUST scores at 3, 6, and 12 months post-surgery, with the primary goal of finding predictors for union timing.
- Results showed that a 3-month mRUST score of ≤8 indicated a higher chance of reoperation, and factors such as tobacco use and open fractures correlated with delayed healing times.
Article Synopsis
- - The study aimed to identify risk factors for unplanned reoperations related to union promotion or deep surgical-site infections (DSSI) in patients with periprosthetic distal femur fractures treated with lateral distal femoral locking plates (LDFLPs).
- - Conducted across ten level-I trauma centers, the retrospective cohort study focused on patients diagnosed with specific fracture types between January 2012 and December 2019 while excluding those with pathological fractures or less than three months of follow-up.
- - Results showed an 8.3% reoperation rate for union promotion linked to factors like higher body mass index and more screws in the distal segment, while no significant factors were identified for DSSI-related reoperations.
Article Synopsis
- - The study aimed to evaluate the clinical and functional outcomes of nail-plate fixation (NPF) for distal femur fractures and to compare these outcomes with those of patients treated with single lateral locking plates.
- - Conducted at ten trauma centers, the retrospective cohort study found that NPF resulted in significantly lower rates of unplanned reoperations and varus collapse compared to the lateral locking plate treatment group.
- - The researchers concluded that NPF is a promising option for complex fractures, with larger studies recommended to further identify which patients benefit most from this treatment.
Objective: To identify technical factors associated with nonunion after operative treatment with lateral locked plating.
Design: Retrospective cohort study.
Setting: Ten Level I trauma centers.
Unlabelled: Many investigations have evaluated local and systemic consequences of intramedullary (IM) reaming and suggest that reaming may cause, or exacerbate, injury to the soft tissues adjacent to fractures. To date, no study has examined the effect on local muscular physiology as measured by intramuscular pH (IpH). Here, we observe in vivo IpH during IM reaming for tibia fractures.

Design: Multicenter retrospective cohort study.
Setting: Ten Level-I trauma centers.
Objectives: To identify potentially modifiable risk factors for deep surgical site infection after distal femur fracture.
Design: Multicenter retrospective cohort study.
Setting: Ten Level-I trauma centers.
Background: The purpose of this study is to compare the risk of peri-operative complication events associated with allogenic and autogenic grafts during routine follow-up for six months after primary arthroscopic anterior cruciate ligament (ACL) reconstruction surgery.
Methods: A retrospective cohort study identified patients that underwent ACL reconstruction via an arthroscopically assisted single tunnel technique. Fixation was primarily cortical suspension (endobutton) from the femora and bicortical fixation (Washer-loc) in the tibia.
