RESUMO
Importance: Surgery within 24 hours after a hip fracture improves patient morbidity and mortality, which has led some hospitals to launch quality improvement programs (eg, targeted resource management, documented protocols) to address delays. However, these programs have had mixed results in terms of decreased time to surgery (TTS), identifying an opportunity to improve the effectiveness of interventions. Objective: To identify the contextual determinants (site-specific barriers and facilitators) of TTS for patients with hip fracture across diverse hospitals. Design, Setting, and Participants: This qualitative mixed-methods study used an exploratory sequential design that comprised 2 phases. In phase 1, qualitative semistructured interviews were conducted with stakeholders involved in hip fracture care (orthopedic surgeons or residents, emergency medicine physicians, hospitalists, anesthesiologists, nurses, and clinical or support staff) at 4 hospitals with differing financial, operational, and educational structures. Interviews were completed between May and July 2021. In phase 2, a quantitative survey assessing contextual determinants of TTS within 24 hours for adult patients with hip fracture was completed by orthopedic surgeon leaders representing 23 diverse hospitals across the US between May and July 2022. Data analysis was performed in August 2022. Main Outcomes and Measures: Thematic analysis of the interviews identified themes of contextual determinants of TTS within 24 hours for patients with hip fracture. The emergent contextual determinants were then measured across multiple hospitals, and frequency and distribution were used to assess associations between determinants and various hospital characteristics (eg, setting, number of beds). Results: A total of 34 stakeholders were interviewed in phase 1, and 23 surveys were completed in phase 2. More than half of respondents in both phases were men (19 [56%] and 18 [78%], respectively). The following 4 themes of contextual determinants of TTS within 24 hours were identified: availability, care coordination, improvement climate, and incentive structure. Within these themes, the most commonly identified determinants across the various hospitals involved operating room availability, a formal comanagement system between orthopedics and medicine or geriatrics, the presence of a physician champion focused on timely surgery, and a program that facilitates improvement work. Conclusions and Relevance: In this study, contextual determinants of TTS within 24 hours for patients with hip fracture varied across hospital sites and could not be generalized across various hospital contexts because no 2 sites had identical profiles. As such, these findings suggest that guidance on strategies for improving TTS should be based on the contextual determinants unique to each hospital.

PURPOSE: This study evaluated the influence of fracture obliquity and locking screw configuration on interfragmentary motion during torsional loading of distal metaphyseal tibial fractures fixed by intramedullary (IM) nailing. METHODS: The stability of six IM nail locking screw configurations used to fix distal metaphyseal tibial fractures of various obliquities was evaluated. A coronal osteotomy from proximal lateral to distal medial was made in sawbone tibiae at different obliquities from 0° to 60°. After fixation, motion at the fracture was assessed during internal and external rotation tests to 7 Nm under two compressive loading conditions: 20 N and 500 N. RESULTS: With results organized by interlocking configuration, significant differences in interfragmentary rotation between fracture obliquities are observed when the number of interlocking screws is decreased to one distal static and one proximal dynamic during internal rotation. During external rotation testing, significant rotational differences between fracture obliquities are encountered with two distal static screws and one proximal dynamic. No significant differences were seen between different distal interlocking screw orientations (two parallel versus perpendicular distal screws) for all fracture obliquity patterns tested. CONCLUSION: Fracture obliquity influences rotational stability which can be mitigated by interlocking screw configurations when nailing distal tibia fractures. At least two distal and one proximal interlocking screw in a static mode is recommended to resist torsional loading of distal tibia fractures undergoing intramedullary nailing. The addition of more interlocking screws than this did not significantly alter control of torsional displacement with load.

PURPOSE: The use of routine physical therapy (PT) and occupational therapy (OT) after certain hand procedures, such as carpal tunnel release, remains controversial. The objective of this study was to evaluate baseline use, the change in use, variation in prescribing patterns by region, and costs for PT/OT after common hand procedures. METHODS: Outpatient administrative claims data from patients who underwent procedures for carpal tunnel syndrome, trigger finger, carpometacarpal arthritis, de Quervain tenosynovitis, wrist ganglion cyst, and distal radius fracture were abstracted from the Truven Health MarketScan database from 2007 to 2015. The incidence of therapy and total reimbursement of therapy per patient were collected for each procedure over a 90-day postoperative observational period. Trends in use of therapy over time were described with average compound annual growth rates (CAGRs), a way of quantifying average growth over a specified observation period. Variations in the incidence of PT/OT use across 4 census regions were assessed. RESULTS: The incidence of 90-day utilization of PT and OT after hand procedures was 14.0% and increased for all procedures during the observation period with an average CAGR of 8.3%. Cost per therapy visit was relatively stable when adjusted for inflation, with an average CAGR of 0.63%. Patients in the northeast had a significantly higher incidence of PT/OT use than those in the south and west for all procedures except carpometacarpal arthritis. CONCLUSIONS: Use of PT and OT has increased over time after common hand procedures. Geographical variation in the utilization rate of these services is substantial. Limiting unwarranted variation of care is a health policy strategy for increasing value of care. TYPE OF STUDY/LEVEL OF EVIDENCE: Outcomes Research II.

The indications for the use of intramedullary (IM) nails have been extended to include extra-articular distal metaphyseal tibia fractures. We hypothesize that interfragmentary motion during physiologic compressive loading of distal tibia fractures is influenced by fracture obliquity and can be modulated by interlocking screw configuration. Sawbone specimens were osteotomized with frontal plane obliquities ranging from 0° to 60° and then fixed by IM nailing with six interlocking screw configurations. Interfragmentary motion was evaluated during loading in axial compression to 1000 N. Comparisons of interfragmentary motions were made (1) between configurations for the various fracture obliquities and (2) between fracture obliquities for the various screw configurations using a mixed-effects regression model. As the degree of fracture obliquity increased, significantly more interfragmentary displacement was shown in configurations with two distal interlocking screws and one proximal screw set in dynamic mode. Fracture obliquity beyond 30° causes demonstrated instability in configurations with less than two distal locking screws and one proximal locking screw. Optimizing the available screw configurations can minimize fracture site motion and shear in distal tibial fractures with larger fracture obliquities.

PURPOSE: Rising costs at the patient level have been recognized and shown to directly influence patient decisions. By understanding patient interests in discussing cost, hand surgeons may better prepare themselves and their practices to communicate costs with patients. METHODS: We surveyed 128 patients at an upper extremity surgery clinic at their 2-week postoperative visit. Survey domains included basic patient demographics and an assessment of patient financial distress, along with questions that rated patient interest with patient-physician financial conversations. These factors included patients' desire for a conversation regarding cost, whether or not patients have discussed cost with their surgeon, barriers to these discussions, and overall views concerning cost containment in hand care. RESULTS: Seven percent of patients discussed the costs of their surgical care with their physician. Eleven percent of patients reported that a doctor should not discuss the costs of their surgical care. Forty-eight percent of patients reported that a doctor should initiate a conversation regarding costs of care when a new treatment is being considered. Fifty-nine percent of patients agreed that physicians should consider the amount of money a patient will have to pay when choosing a new treatment. CONCLUSIONS: Patients can experience financial hardship as a result of their surgery and some patients are interested in discussing costs with their doctor. Patients indicated that doctors should be concerned with lowering the costs of surgery and should initiate a conversation regarding costs of care when a new treatment is being considered. CLINICAL RELEVANCE: Patients are interested in a conversation regarding their cost of hand surgery care. Making cost data more transparent and available to physicians and patients may facilitate communication regarding cost of care.

BACKGROUND: This study evaluated patients with and without a prosthetic dislocation after reverse total shoulder arthroplasty (RTSA) to identify risk factors for instability. METHODS: Dislocation and nondislocation cohorts were established for analysis in 119 patients who had undergone RTSA at our institution between 2011 and 2014. Preoperative history and parameters pertaining to RTSA design were evaluated for correlation with instability. A logistic regression model was used to analyze independent predictors. RESULTS: Eleven patients (9.2%) demonstrated instability in the early postoperative period. Dislocations occurred at an average of 8 weeks postoperatively (range, 3 days-5 months). The mean follow-up of all patients was 28 months (range, 6-106 months). Postoperative instability was associated with male gender, history of prior open shoulder surgery, and preoperative diagnoses of fracture sequelae, particularly proximal humeral or tuberosity nonunion. Absence of subscapularis repair was an independent predictor of instability. In addition, 5 of the 11 patients (45%) in the instability cohort sustained a second dislocation requiring another operation. CONCLUSIONS: Redislocation after revision surgery for the initial dislocation was an unexpected and alarming finding. Treatment for the initial dislocation event by placement of a thicker polyethylene insert was inadequate in 45% of patients of our cohort and required another revision with a larger glenosphere and thicker humeral inserts. Initial instability after RTSA must be carefully managed, especially in the revision and post-traumatic setting. Exchange to a thicker polyethylene insert only carries a higher risk of recurrent instability.

BACKGROUND: Modular femoral stem provides flexibility in femoral reconstruction, ensuring improved "fit and fill". However, there are risks of junction failure and corrosion, as well as cost concerns in the use of modular femoral stems. METHODS: We reviewed prospectively-gathered clinical and radiographic data on revision total hip arthroplasties (THAs) performed from 2001-2007 using modular, cementless femoral component performed by the 2 senior authors. Patients with a minimum follow-up of 7 years were included in this study. RESULTS: Sixty-four patients (68 hips) with a median age of 68 ± 14 years (range 40-92 years) at revision THA were included. The median follow-up was 11.0 ± 1.8 years (range 7-14). Harris hip score, femoral stem subsidence, and stem osseointegration were recorded. The Harris hip score improved from an average of 38.1-80.1 (P < .01). Five hips had one or more dislocations. Seven patients underwent reoperations, 3 of which did not involve the stem. Four stems required revision because of infection, recurrent dislocation, or suboptimal implant position. Survival rates for any reasons and revision for femoral stems were 90% and 94%, respectively, at the most recent follow-up. Four stems subsided more than 5 mm, but established stable osseointegration thereafter. Seven nonloose stems (10.2%) demonstrated radiolucent lines in Gruen zones 1 and 7. No complications regarding the modular junction were encountered. CONCLUSION: Modular, cementless, extensively porous-coated femoral components have demonstrated intermediate-term clinical and radiographic success. Initial distal intramedullary fixation ensures stability, and proximal modularity further maximizes fit and fill.

Abnormal patellofemoral joint alignment has been discussed as a potential risk factor for patellofemoral disorders and can impact the longevity of any elite athlete's career. The prevalence of abnormal patellofemoral congruence in elite American football athletes is similar to the general population and does not have a relationship with quadriceps isokinetic testing. A total of 125 athletes (220 knees) from the 2011 National Football League (NFL) Combine database who had radiographic and isokinetic studies were reviewed. Congruence angles (CA) and lateral patellofemoral angles (LPA) were calculated on a Merchant radiographic view. Isokinetic testing was used to determine quadriceps-to-hamstring strength (Q/H) ratio and side-to-side deficits. The relationships between abnormal CA and LPA with Q/H ratios, side-to-side deficits, and body mass index (BMI) were examined in separate logistic regression models. A Chi-square test was used to examine the association between CA and player position. Of all, 26.8% of the knees (95% CI: 21.1-33.2%) had an abnormal CA. Knees with normal CA (n = 161) did not significantly differ from those with an abnormal CA (n = 59) in Q/H ratios (mean: 0.699 vs. 0.728, p = 0.19) or side-to-side quadriceps deficits (mean: 4.0 vs. 1.24, p = 0.45). For each point increase in BMI, the odds ratio (OR) of abnormal congruence increased by 11.4% (p = 0.002). Of all the knees, 4.1% (95% CI: 1.9-7.6%) had an abnormal LPA, and this was not associated with Q/H ratios (p = 0.13). For each point increase in BMI, the odds of abnormal LPA increased by 16% (p = 0.036). CA abnormality had much higher odds of having an abnormal LPA (OR: 5.96, p = 0.014). We found that abnormal patellofemoral radiographic alignment in elite American football players is relatively common and there was no association with isokinetic testing.
