ABSTRACT

This study was undertaken to determine the incidence, need for intervention, and time to resolution of pseudosubluxation of the shoulder in pediatric proximal humerus fractures. One hundred and ninety-nine radiographs (199 x-rays) were analyzed for pseudosubluxation of the shoulder following pediatric proximal humeral fractures. Pseudosubluxation occurs when the center of the humeral head aligns with the inferior one-fourth of the glenoid. Fourteen patients met the inclusion criteria for pseudosubluxation. The nonoperative cohort consisted of 100 females and 93 males and the operative cohort consisted of 3 males and 3 females. Total 14 children out of 199 had pseudosubluxation. Ten pseudosubluxations were seen 7 days postinjury and four were noted immediately after injury. Pseudosubluxation was seen in nine boys (64%) and five girls (36%) in the nonoperative group. Increased relative risk (RR) was associated with: fall >3 m (RR = 25.7; 95% CI, 2.7-244.0), motorized transport (RR = 11.7; 95% CI, 1.41-96.03) and sports injuries (RR = 11.0, 95% CI, 1.2-100). No statistical analysis was conducted on the operative group given the small sample. This study establishes incidence, risk factors and expected clinical course for pseudosubluxation following proximal humerus fractures. The overall incidence in the nonoperative cohort was 7.3%, radiographic evidence of pseudosubluxation resolution was available for (n = 10) patients with 100% resolution by 6 weeks. There were no readmissions or complications in the 14 patients. Pseudosubluxation occurrence was significantly increased in four mechanisms: falls >3 m, sports trauma and motor transportation. This study provides the natural history and risk factors for pseudosubluxation following proximal humerus fractures. Pseudosubluxation is more likely to occur in higher energy fracture mechanisms and will resolve without treatment. Level of Evidence: Level III, retrospective cohort.

ABSTRACT

BACKGROUND: Gastrocnemius recession is a common foot and ankle procedure and various techniques that have been utilized are mainly delineated by the anatomic position of the gastrocnemius transection; the 2 common ones are the Baumann and Strayer procedure. Both can adversely affect the sural nerve. The objective of this study was to evaluate the macroscopic changes in the sural nerve following gastrocnemius recession, and to compare the efficacy of the two procedures, regarding the improvement of maximal ankle dorsiflexion. METHODS: Ten fresh-frozen, above knee cadaveric legs were assigned to one of two gastrocnemius recession techniques: Baumann (n = 5) or Strayer (n = 5). A goniometer was used to measure degree of ankle dorsiflexion before and after the surgery. The sural nerve was meticulously dissected and marked with two suture knots, 2 cm apart. The ankle was passively dorsiflexed from 90° to maximal dorsiflexion in 5° degree increments, and the distance between two suture knots was measured at each increment. The distance between the two cut ends of gastrocnemius muscle was measured with the ankle at 90° and at maximal dorsiflexion. RESULTS: Overall, a mean increase in length between the suture knots on the sural nerve was 0.2 cm, from 90° to maximum ankle dorsiflexion (130°); both the Baumann and Strayer techniques resulted in 0.2 cm increase. The mean improvement in maximal ankle dorsiflexion in the Baumann and Strayer group was 22.6° and 22°, respectively. The mean change in distance between the two cut ends of the gastrocnemius muscle in the Baumann and Strayer group was 1.0 cm and 0.9 cm, respectively. CONCLUSION: Increased dorsiflexion of the ankle following Strayer or Baumann gastrocnemius recession resulted in similar macroscopic change in the sural nerve, which may contribute to the development of sural neuritis. Further clinical studies are warranted to assess clinical implications of these findings.

ABSTRACT

BACKGROUND: The number of total hip arthroplasties (THA) being performed has been steadily increasing for decades. With increased primary THA surgical volume, revision THA numbers are also increasing at a steady pace. With the aging, increasingly comorbid patient populations and newly imposed financial penalties for hospitals with high readmission rates, refining understanding of factors influencing readmission following THA is a research priority. We hypothesize that numerous preoperative medical comorbidities and postoperative medical complications will emerge as significant positive risk factors for 30-day readmission. METHODS: ACS-NSQIP database identified patients who underwent revision THA from 2005 to 2015. The primary outcome assessed was hospital readmission within 30 days. Patient demographics, preoperative comorbidities, laboratory studies, operative characteristics, and postsurgical complications were compared between readmitted and non-readmitted patients. Logistic regression identified significant independent risk factors for 30-day readmission among these variables. RESULTS: 10,032 patients underwent revision THA in the ACS-NSQIP from 2005 to 2015; 855 (8.5%) were readmitted within 30-days. Increasing age, the presence of preoperative comorbidities, high ASA class, and increased operative time were significant positively associated independent risk factors for 30-day readmission. Several postoperative medical and surgical complications such as myocardial infarction, stroke, pneumonia, and sepsis demonstrated significant positive associations with readmission. CONCLUSION: Identifying and understanding risk factors associated with readmission allows for the implementation of evidence-based interventions aimed at minimizing risk and reducing 30-day readmission rates following revision THA.

ABSTRACT

Background Complications following orthopedic surgeries are undesirable and costly. A potential method to reduce these costs is to perform traditionally inpatient surgical procedures in the outpatient setting. The purpose of this study is to compare outcomes between inpatient and outpatient settings for elective foot and ankle surgeries using the National Surgical Quality Improvement Program (NSQIP) database. Methods Patients with Current Procedural Terminology (CPT) codes specific to orthopedic foot and ankle surgery were identified from the 2011-2015 American College of Surgeons NSQIP database. Demographics, comorbidities, and complications were compared between patients undergoing inpatient and outpatient procedures. Results Patients receiving inpatient surgery were significantly older and more frequently male. Black patients were significantly more likely to undergo inpatient surgery than outpatient surgery while white patients were significantly more likely to undergo outpatient surgery. Outpatients had a significantly higher mean body mass index (BMI) than inpatients. Smokers were at a significantly greater risk of undergoing inpatient surgery than outpatient surgery. Outpatients had significantly longer operative times, were more likely to receive general anesthesia, had a lower American Society of Anesthesiologists (ASA) class, were more likely to be functionally independent, and were less likely to expire postoperatively. Patients who received surgery as an inpatient were significantly more likely to have comorbidities as compared to outpatients. The overall risk of surgical complications was significant between groups with 8.6% in the inpatient group and 2.0% in the outpatient group. The overall risk of medical complications was 16.9% in the inpatient group and 1.7% in the outpatient group. Similar to the surgical complications, inpatients were significantly more likely to sustain each of the individual medical complications except for stroke/CVA and venous thromboembolism. Conclusions Outpatient management is associated with decreased postoperative complications in select patients. Performing more operations in the outpatient setting in select patients may be beneficial for cost reduction and patient satisfaction.

ABSTRACT

BACKGROUND: When surgery is indicated for hallux rigidus, toe arthroplasty is an alternative procedure to arthrodesis for patients who wish to preserve toe range of motion. Our study investigated midterm outcomes of first metatarsophalangeal joint (MTPJ) arthroplasty in an effort to discern whether or not partial or total joint replacement confers benefit in these patients. METHODS: A systematic review of MTPJ arthroplasty was performed for the years 2000 to 2017. A Forest plot was created comparing preoperative and postoperative American Orthopedic Foot and Ankle Score (AOFAS), Visual Analogue Scale (VAS), and range of motion (ROM) results for both hemitoe and total-toe arthroplasty. Statistical analysis was performed. RESULTS: Mean postoperative AOFAS scores in patients undergoing hemiarthroplasty improved by 50.7 points (95% CI = 48.5, 52.8), whereas the mean AOFAS score improvement in total joint arthroplasty patients was 40.6 points (95% CI = 38.5, 42.8). VAS outcomes were comparable. Mean postoperative MTPJ ROM improved by 43.0° (95% CI = 39.3°, 46.6°) in hemitoe patients, which exceeded the mean ROM improvement of 32.5° (95% CI = 29.9°, 35.1°) found in total joint arthroplasty cases. A meta-analysis revealed no significant difference. CONCLUSION: Hemisurface implants in MTPJ arthroplasty may improve postoperative AOFAS and ROM results to a greater extent than total-toe devices. LEVEL OF EVIDENCE: Level IV: Systematic review.
