Glenohumeral arthrodesis outcomes and complications: a systematic review

BACKGROUND

The purpose of this study was to systematically review the evidence in the literature to determine the clinical outcomes following glenohumeral arthrodesis.

METHODS

Two independent reviewers performed a literature search in the PubMed database based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies were included if they reported on outcomes following shoulder arthrodesis from the years of 2000-2022. Functional outcomes that were collected included the Subjective Shoulder Value, American Shoulder and Elbow Surgeons shoulder index score, visual analog scale pain score, and Oxford Shoulder Score. Range-of-motion data were also collected.

RESULTS

This review included 17 studies, with a total of 316 patients, that met the inclusion criteria. The majority of the patients were male (67.4%), and the average age was 38.4 years (range, 7-82 years). The overall fusion rate was 88.7%, and the time to fusion was on average, 3.9 months (range, 2-8 months). Shoulder arthrodesis resulted in improvement in each of the functional outcomes assessed: Subjective Shoulder Value (preoperatively, 18.8; postoperatively, 43.9; and percent change, 132.8%), American Shoulder and Elbow Surgeons shoulder index score (postoperatively, 62.1), visual analog scale pain score (preoperatively, 8.5; postoperatively, 3.03; and percent change, 62.4%), and Oxford Shoulder Score (preoperatively, 9.4; postoperatively, 30.9; and percent change, 328.7%). The abduction, forward flexion, external rotation, and internal rotation range-of-motion measurements postoperatively were 57°, 64°, 3°, and 48°, respectively. Complications were reported in 33.6% of patients, with fractures (20.9%) and infections (18.6%) being the most common sources of complication.

CONCLUSION

Shoulder arthrodesis provides improvement in functional outcomes for end-stage glenohumeral injuries; however, it is also associated with high rates of complications.

Analyzing the Quality, Reliability, and Educational Value of ACL Rehabilitation Exercises on TikTok: A Cross-Sectional Study

Background

Videos relating to rehabilitation exercises for common injuries relevant to younger populations such as anterior cruciate ligament (ACL) tear receive high view counts on social media platforms such as TikTok.

Purpose/Hypothesis

The purpose of this study was to analyze the quality, reliability, and educational value of TikTok videos among the patient population for ACL injury. It was hypothesized that TikTok videos related to ACL rehabilitation exercises would lack quality, reliability, and educational value.

Study Design

Cross-sectional study.

Methods

TikTok was queried for relevant videos using the hashtags "#ACLrehab" and "#ACLexercises." For each included video, the type of uploader (general user or health care professional) was identified. In addition, the number of views, likes, shares, comments, and favorites for each included video was recorded, and the content of each video was graded using the DISCERN (a well-validated informational analysis tool) and the ACL exercise education score (ACLEES - a custom-designed tool for the evaluation of ACL-related exercises).

Results

A total of 111 videos with 5,520,660 cumulative views were included; the median number of views per video was 9801.0 (interquartile range [IQR], 3583.0-28,000.0). Of these videos, 84 and 27 were created by the general public and health care professionals, respectively. The videos collectively received 335,577 likes, 2969 comments, 22,856 favorites, and 6142 shares, with a median of 439 (IQR, 111-1374), 10 (IQR, 2.5-25.5), 54 (IQR, 18-172.5), and 12 (IQR, 2-36), respectively. The tabulated scores for the DISCERN and ACLEES between general users and health care professionals were all statistically nonsignificant. Health care professionals had a higher percentage of videos with a "very poor" DISCERN score in comparison with the general public (66.67% vs 53.57%, respectively).

Conclusion

The overall educational value of the TikTok videos related to ACL rehabilitation exercises was very poor. Health care professionals should be aware of the broad distribution of ACL rehabilitation exercise videos that are accessible on TikTok and raise awareness of the deficiencies of the platform as a medium for educational medical-related information.

Peripheral Nerve Block Delays Mobility and Increases Length of Stay in Patients With Geriatric Hip Fracture

INTRODUCTION

Peripheral nerve blocks (PNB) has been increasingly used in the care of patients with geriatric hip fracture to reduce perioperative opiate use and the need for general anesthesia. However, the associated motor palsy may impair patients' ability to mobilize effectively after surgery and subsequently may increase latency to key mobility milestones postoperatively, as well as increase inpatient length of stay (LOS). The aim of this study was to investigate time-to-mobility milestones and length of hospital stay between peripheral, epidural, and general anesthesia.

METHODS

A retrospective review identified 1,351 patients aged 65 years or older who underwent surgery for hip fracture between 2012 and 2018 at a single academic health system. Patients were excluded if baseline nonambulatory, restricted weight-bearing postoperatively, or sustained concomitant injuries precluding mobilization, with a final cohort of 1,013 patients. Time-to-event analyses for discharge and mobility milestones were assessed using univariate Kaplan-Meier and multivariate Cox proportional hazard regression analyses.

RESULTS

PNB was associated with delayed postoperative time to ambulation (P < 0.001) and time to out-of-bed (P = 0.029), along with increased LOS (P < 0.001). Epidural anesthesia was associated with less delay to first out-of-bed (P = 0.002), less delay to ambulation (P = 0.001), and overall reduced length of stay (P < 0.001).

DISCUSSION

PNB was associated with slower mobilization and longer hospitalization while epidural anesthesia was associated with quicker mobilization and shorter hospital stays. Epidural anesthesia may be a preferable anesthesia choice in patients with geriatric hip fracture when possible.

976. E coli Periprosthetic Joint Infections: Poor Infection Clearance at One Year

Background

Escherichia Coli (E coli) is a gram-negative rod that can cause devastating periprosthetic joint infections (PJIs) in patients with total hip and knee replacements (THA/TKA). Minimal literature exists on outcomes of E coli PJIs.

Methods

Retrospective review of our institution’s electronic medical record from 2009-2020 identified 21 patients that met MusculoSkeletal Infection Society criteria for E coli hip or knee PJI. Primary outcome was 1-year infection clearance - eradication of infection off antibiotics with no further surgeries for 1 year after completion of standard postoperative antibiotics. Minimum followup was 1 year.

Results

We analyzed 21 patients (mean age 66.6 yrs, 47.6% male, 23.8% nonWhite, 38.1% knee PJIs). There were 11 acute, 8 acute hematogenous (AH), and 2 chronic PJIs. Several patients had recent gastrointestinal/urinary tract surgery (14.3%), recurrent urinary tract infections (9.5%), or >1 E coli urine culture <1 mo pre-PJI (14.3%). Surgical treatments included DAIR (66.7%), 2-stage revision (14.3%), Girdlestone/Resection Arthroplasty (G/RA; 14.3%), and fusion (4.8%), with 7.1%, 100%, 66.7%, and 100% 1-year infection clearance, respectively, and 33.3% 1-year infection clearance overall (p=.001). Common reasons for treatment failure were reinfection requiring surgery (57.1%) and chronic antibiotics (38.1%). Patients clear at 1 year had a longer mean time from most recent surgery to index PJI surgery (48.7 vs 7mo;p=.043) and more AH than acute or chronic infections (54.6% vs 27.3% vs 18.2%;p=.0412). Patients who were not clear at 1 year had more acute infections (80% vs 20% AH;p=.0412). The E coli PJI persisted in 23.8% of patients. Outcomes at final followup included G/RA (28.6%), original prosthetic (28.6%), new prosthetic (19%), above knee amputation (9.5%), destination spacer (9.5%), and arthrodesis (4.8%).

Conclusion

E coli PJI 1-year infection clearance is poor, with DAIR being the most common yet least effective surgical treatment. Most E coli PJIs occurred postoperatively as opposed to hematogenously, as is sometimes assumed. This serves as a foundation for future studies evaluating E coli treatment outcomes.
