Long-Term Results of Hemiarthroplasty Compared With Arthrodesis for Osteoarthritis of the First Metatarsophalangeal Joint.

If operative treatment is opted for grade 3 and 4 osteoarthritis of the first metatarsophalangeal joint, arthrodesis is considered the standard of care. However, if preservation of joint mobility is preferred, implant arthroplasty could be favored. Previous studies have suggested hemiarthroplasty might result in less pain, better function, and greater patient satisfaction compared with arthrodesis. However, these studies only evaluated short-term results (range 2.2 to 6.6 years). The aim of our study was to determine whether patients treated with hemiarthroplasty would show better postoperative outcomes compared with those treated with arthrodesis after ≥5 years after surgery. The American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal (AOFAS-HMI) scale score was used as the primary outcome measure. Secondary outcomes addressed satisfaction rates, patient procedure recommendation, and number of unplanned repeat surgical procedures. We also addressed the influence of the procedures on daily activities (work and sports), the influence of smoking on the postoperative results, and the costs for both procedures. A total of 47 primary arthrodeses and 31 hemiarthroplasties performed between January 2005 and December 2011 were evaluated. After a mean follow-up period of 8.3 (range 5 to 11.8) years, the mean AOFAS-HMI scale score after arthrodesis and hemiarthroplasty was 72.8 ± 14.5 and 89.7 ± 6.6, respectively (p = .001). The patients were significantly more pleased after hemiarthroplasty (p < .001), and this procedure was recommended more often (p < .001). The number of unplanned repeat surgical procedures did not differ between the 2 groups. Patients resumed sports activities significantly sooner after hemiarthroplasty (p = .002). The overall crude costs were similar for both procedures. Our results have shown more favorable postoperative outcomes for hemiarthroplasty compared with arthrodesis as operative treatment of osteoarthritis of the first metatarsophalangeal joint after a mean follow-up period of 8.3 years.

Operative Treatment for Osteoarthritis of the First Metatarsophalangeal Joint: Arthrodesis Versus Hemiarthroplasty.

Controversy remains whether hemiarthroplasty or arthrodesis results in better postoperative outcomes for patients who request surgery for advanced osteoarthritis of the first metatarsophalangeal joint. Therefore, we tested the primary null hypothesis that the 2 treatment groups would not differ in the postoperative American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal scale scores after a follow-up period of ≥1 year. Secondary analyses addressed the satisfaction rates, percentage of patients who would recommend the procedure, and unplanned repeat operation rates. A total of 58 primary arthrodeses and 36 hemiarthroplasties performed from January 2005 to December 2010 were evaluated at ≥1 year postoperatively. At a mean average of 4 (range 1 to 7) years after surgery, the mean American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal interphalangeal scale score was 77.5 ± 18.5 in the arthrodesis group and 77.8 ± 12.0 in the arthroplasty group (p = .93). The number of repeat operations did not differ between these 2 groups, and patients treated with hemiarthroplasty reported greater mean satisfaction (p = .04). These results showed that the symptom intensity and magnitude of disability were similar at ≥1 year after arthrodesis or hemiarthroplasty for osteoarthritis of the first metatarsophalangeal joint, although the patients were subjectively more pleased with the results after hemiarthroplasty.

Insert dissociation after fixed bearing PS constrained Genesis II total knee arthroplasty. A case series of nine patients.

Dissociation of the polyethylene insert after fixed bearing posterior stabilized Genesis II total knee arthroplasty has been rarely described. We present a case series of nine patients with a dissociation of the insert within a period of two years after surgery. Revision surgery was performed in all patients. In this report we discuss clinical presentation, patient characteristics and possible etiologies for tibial insert dissociation seen in the presented cases. In conclusion, tibial insert dissociation does not lead to a uniform clinical presentation. Therefore, in this point of view regular physical examination and imaging after TKA regardless the presence of symptoms seems to be indicated.

In-Hospital Outcomes after Hemiarthroplasty versus Total Hip Arthroplasty for Isolated Femoral Neck Fractures.

BACKGROUND: Previous studies suggest total hip arthroplasty may have some benefits compared to hemi-arthroplasty for displaced intracapsular femoral neck fractures in patients more than 60 years of age. The primary research question of our study was whether in-hospital adverse events, post-operative length of stay (LOS) and mortality in patients 60 year of age or older differed between total hip and hemi-arthroplasty for femoral neck fracture. METHODS: We obtained data on 82951 patients more than 60 years of age with an isolated femoral neck fracture treated with either hemi-arthroplasty or total hip arthroplasty in 2009 or 2010 from the National Hospital Discharge Survey (NHDS) database. The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9, CM) was used to code diagnoses, comorbidities, complications, and procedures. RESULTS: Controlling for demographics and comorbidities, patients treated with hemi-arthroplasty had a 40% (95% CI 1.4-1.5) higher risk of adverse events compared to patients treated with a total hip arthroplasty. Length of stay and in-hospital mortality did not differ between these groups. CONCLUSIONS: The observed advantage for total hip arthroplasty might reflect greater infirmity in hemi-arthroplasty patients that was not accounted for by ICD-9 codes alone.

The influence of mindfulness on upper extremity illness.

BACKGROUND: Previous studies suggest a benefit of mindfulness-based interventions on pain conditions. This study addresses the null hypothesis that mindfulness is not correlated with pain intensity or magnitude of disability in orthopedic upper extremity conditions. METHODS: In a prospective cohort, the correlation of the two separate aspects of mindfulness-acceptance and awareness-with disability and pain intensity was tested in patients with nonacute upper extremity conditions. Regression analyses were performed to determine factors associated with arm-specific disability and pain intensity. RESULTS: Awareness and acceptance both correlated with arm-specific disability, but only awareness was retained as a predictor in the best multivariable model. Neither awareness nor acceptance correlated with pain intensity. Pain interference and symptoms of depression accounted for more of the variation in disability and pain intensity. CONCLUSION: Improved mood and decreased pain interference (a greater sense that one can accomplish one's goals in spite of pain) may be more fruitful than increased mindfulness for patients with nonacute conditions of the upper extremity.

Higher Charlson Comorbidity Index Scores are associated with readmission after orthopaedic surgery.

BACKGROUND: The Charlson Comorbidity Index (CCI) originally was developed to predict mortality within 1 year of hospital admission in patients without trauma. As it includes factors associated with medical and surgical complexities, it also may be useful as a predictive tool for hospital readmission after orthopaedic surgery, but to our knowledge, this has not been studied. QUESTIONS/PURPOSES: We asked whether an increased score on the CCI was associated with (1) readmission, (2) an increased risk of surgical site infection or other adverse events, (3) transfusion risk, or (4) mortality after orthopaedic surgery. METHODS: A total of 30,129 orthopaedic surgeries performed between 2008 and 2011 without any orthopaedic surgery in the preceding 30 days were analyzed. International Classification of Diseases, 9(th) Revision codes were used to identify diagnoses, procedures, surgery-related adverse events, surgical site infection, and comorbidities as listed in the updated and reweighted CCI. A total of 913 patients (3.0%) were readmitted within 30 days after discharge; in 393 (1.4%) patients adverse events occurred; 417 patients (1.4%) had a surgical site infection develop; 211 (0.7%) needed transfusions, and 56 (0.2%) died within 30 days after surgery. Ordinary least squares regression analyses were used to determine whether the CCI was associated with these outcomes. RESULTS: The CCI accounted for 10% of the variation in readmissions. Every point increase in CCI score added an additional 0.45% risk in readmission for patients undergoing arthroplasty, 0.63% for patients undergoing trauma surgery, and 0.9% risk for patients undergoing spine surgery (all p < 0.01). The CCI was not associated with surgical site infection or other adverse events, but accounted for 8% of the variation in transfusion rate and 10% of the variation in mortality within 30 days of surgery. CONCLUSIONS: The CCI can be used to estimate the risk of readmission after arthroplasty, hand and upper extremity surgery, spine surgery, and trauma surgery. It also can be used to estimate the risk of transfusion after arthroplasty, spine, trauma, and oncologic orthopaedic surgery and the risk of mortality after shoulder, trauma, and oncologic orthopaedic surgery.
