ABSTRACT
This study investigated predictive factors for return to play among National Football League athletes after operative treatment of ankle fractures and the impacts of these injuries on career longevity and player performance. Athletes who underwent surgery to repair ankle fractures from the 2013 to 2017 seasons were identified from injury reserve lists and press releases. Demographics and season metrics were collected before and after the injury. Statistical analysis assessed for differences in recorded variables between injured and uninjured players. Thirty-one players met study inclusion criteria. Twenty-two (71%) athletes successfully returned to play. Players who did not return showed no significant differences (P>.05) in position, age, body mass index, number of games or seasons played preinjury, or snaps per game the season prior to injury and had a significantly lower (42.6%, P=.013) preinjury season approximate value (SAV) compared with returning players. Returning athletes showed no significant differences (P>.05) in SAV or snaps per game compared with their preinjury season or with uninjured controls. A high preinjury SAV is associated with successful return to play. No difference in game time or performance metrics was detectable between returning players and uninjured controls, or between preinjury and postinjury seasons. [Orthopedics. 2024;47(1):22-27.].

BACKGROUND: When lateral ankle sprains progress into chronic lateral ankle instability (CLAI), restoring precise anatomic relationships of the lateral ankle ligament complex (LALC) surgically is complex. This study quantifies the radiographic relationships between the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and prominent osseous landmarks visible under fluoroscopy to assist in perioperative practices for minimally invasive surgery for CLAI. METHODS: Ten fresh frozen ankle specimens were dissected to expose the LALC and prepared by threading a radiopaque filament through the ligamentous footprints of the ATFL and CFL. Fluoroscopic images were digitally analyzed to define dimensional characteristics of the ATFL and CFL. Directional measurements of the ligamentous footprints relative to the lateral process of the talus and the apex of the posterior facet of the calcaneus were calculated. RESULTS: Dimensional measurements of the ATFL were a mean length of 9.3 mm, fibular footprint of 9.4 mm, and talar footprint of 9.1 mm. Dimensional measurements of the CFL were a mean length of 19.4 mm, fibular footprint of 8.2 mm, and calcaneal footprint of 7.3 mm. From the radiographic apparent tip of the lateral process of the talus, the fibular attachment of the ATFL was found 13.3 mm superior and 4.4 mm posterior, whereas the talar attachment was found 11.5 mm superior and 4.8 mm anterior. From the radiographic apparent posterior apex of the posterior facet of the calcaneus, the fibular attachment of the CFL was found 0.2 mm inferior and 6.8 mm anterior, whereas the calcaneal attachment was found 14.3 mm inferior and 5.9 mm posterior. CONCLUSION: The ATFL and CFL were radiographically analyzed using radiopaque filaments to outline the ligamentous footprints in their native locations. These ligaments were also localized with reference to 2 prominent osseous landmarks. These findings may assist in perioperative practices for keyhole incision placement and arthroscopic guidance. Perfect lateral ankle joint imaging with talar domes superimposed is required to be able to do this. CLINICAL RELEVANCE: Radiographic evaluation of the ATFL and CFL with reference to prominent osseous landmarks identified under fluoroscopy may assist in perioperative practices for minimally invasive surgery to address CLAI for keyhole incision placement and arthroscopic guidance.

CASE: An 85-year-old woman with a history of bladder mesh sling placement sustained a pelvic fracture and extraperitoneal bladder rupture after a ground-level fall. The patient underwent cystorrhaphy and percutaneous anterior column screw placement. Free air was identified on abdominal computed tomography scan on postoperative day 5. Exploratory laparotomy revealed a sigmoid colon perforation and extensive bowel adhesions to the anterior pelvis. CONCLUSION: This is the first report describing bowel injury and associated bladder rupture in a pelvic fragility fracture related to a prior bladder mesh sling. This case highlights the importance of obtaining a thorough surgical history when treating pelvic injuries.

Background: Extensive research collaborations exist between researchers from high-income countries (HICs) and those from low-income countries (LICs) and lower-middle-income countries (LMICs). Previous research has suggested that authors from LICs and LMICs are underrepresented as first and last authors in the orthopaedic literature on local populations, particularly in LICs. We present a bibliometric analysis of authorship solely in studies published in orthopaedic journals that are based in LICs and LMICs. Methods: The Global Index Medicus was queried, and all articles published from January 1, 2010, to December 31, 2021, in journals with a focus on orthopaedic surgery that were based in an LIC or an LMIC were included. Logistic regressions were calculated to assess the predictors of local authorship. Results: Over 92% of studies included in our analysis had first or last authors from LICs or LMICs. In terms of study type, the majority (89%) of studies were clinical, although largely of low-level evidence (78% of clinical studies were case reports, case series, or descriptive studies). None received funding. LIC or LMIC first authorship and last authorship were less likely for most types of nonclinical studies. LIC or LMIC first authorship was more likely when there were more study authors. LIC or LMIC first authorship and last authorship were less likely when there were more countries affiliated with the study authors. Finally, when compared with studies with only LIC or LMIC authors, those with a combination of HIC and LIC or LMIC authors had significantly lower rates of LIC or LMIC first authorship (93.3% versus 62.5%) and last authorship (97.7% versus 70.8%). Conclusions: Our study presents one of the first analyses to assess authorship patterns in the orthopaedic literature of locally published journals in LICs and LMICs. Future studies are needed to contextualize our findings within a broader bibliometric landscape in order to better address the ongoing challenges to building research capacity in LICs and LMICs. Clinical Relevance: Our study highlights important observations regarding authorship in international, collaborative research in orthopaedics.
ABSTRACT
A growing body of research has suggested that the experience of injustice, psychological contract breach, or unfairness can adversely impact an employee's health. We conducted a meta-analysis to examine the effects of unfairness perceptions on health, examining types of fairness and methodological characteristics as moderators. Results suggested that perceptions of unfairness were associated with indicators of physical and mental health. Furthermore, psychological contract breach contributed to the prediction of strain-related indicators of health above and beyond that accounted for by injustice alone.

Social projection is the tendency to expect similarities between oneself and others. A review of the literature and a meta-analysis reveal that projection is stronger when people make judgments about ingroups than when they make judgments about outgroups. Analysis of moderator variables further reveals that ingroup projection is stronger for laboratory groups than for real social categories. The mode of analysis (i.e., nomothetic vs. idiographic) and the order of judgments (i.e., self or group judged first) have no discernable effects. Outgroup projection is positive, but small in size. Together, these findings support the view that projection can serve as an egocentric heuristic for inductive reasoning. The greater strength of ingroup projection can contribute to ingroup-favoritism, perceptions of ingroup homogeneity, and cooperation with ingroup members.
