ABSTRACT
BACKGROUND: Distal triceps ruptures are rare, and complete ruptures are commonly treated with surgery. Studies of patients in small cohorts with distal triceps tear have reported outcomes and risk factors; however, large-scale data are scant. This study seeks to determine current trends, outcomes, and risk factors of distal triceps tears. METHODS: Within a large insurance claims database, distal triceps repair patients were identified through Current Procedural Terminology coding with concomitant distal triceps International Classification of Diseases, 9th Revision/10th Revision diagnosis codes and 1-year active status before and after surgery. Demographics, total costs, 90-day complications, and revision rates within 1 year of index surgery were analyzed. Logistic regression was performed for revision and complication rates using sex, age, and comorbidities (anabolic steroid use, diabetes, ischemic heart disease, tobacco use, rheumatoid arthritis, and chronic kidney disease). RESULTS: A total of 8143 patients were included in the cohort. Male patients and patients aged 40 to 59 years comprised most of the study population. The postoperative complication rate was 5.8%, and the 1-year revision rate was 2.6%. Male sex, age >60 years, ischemic heart disease, rheumatoid arthritis, and chronic kidney disease were statistically significant risk factors for higher 90-day complication rates. Anabolic steroid use significantly increased the risk of surgical revision. CONCLUSIONS: Distal triceps repairs in this large cohort study occur most frequently in men aged 40 to 59 years. Complications are generally low, with age >60 years, male sex, ischemic heart disease, rheumatoid arthritis, and chronic kidney disease as risk factors for 90-day complications and prior anabolic steroid use as a risk factor for 1-year revision surgery. This information can help to improve education and expectations of this procedure.

INTRODUCTION: The long-term risk of conversion to lumbar fusion is ill-defined for patients with cauda equina syndrome (CES) treated with decompression. This study aimed to identify the rates of fusion in patients with CES and compare those rates with a matched lumbar spinal stenosis (LSS) group. METHODS: Patients with CES who underwent decompression were identified in a national database and matched to control patients with LSS. The rates of conversion to fusion were identified and compared. Multivariate logistic regression analysis identified independently associated risk factors. A subanalysis was conducted after stratifying by timing between CES diagnosis and decompression. RESULTS: The rate of lumbar fusion in the CES cohort was 3.6% after 1 year, 6.7% after 3 years, and 7.8% after 5 years, significantly higher than the LSS control group at all time points (1 year: 1.6%, P = 0.001; 3 years: 3.0%, P < 0.001; 5 years: 3.8%, P < 0.001). CES was independently associated with increased risk of conversion to fusion (odds ratio: 2.13; 95% confidence interval: 1.56 to 2.97; P < 0.001). Surgical timing was not associated with risk of conversion to fusion. CONCLUSIONS: After 5 years, 7.8% of patients with CES underwent fusion, a markedly higher rate compared with patients with LSS. Counseling patients with CES on this increased risk of future surgery is important for patient education and satisfaction.

INTRODUCTION: Reverse total shoulder arthroplasty (rTSA) is gaining popularity as a treatment option for proximal humeral fractures in elderly patients. The impact of surgical timing on outcomes of primary rTSA is unclear. This study compared the rates of revision and complication, and surgery day cost of treatment between acute and delayed primary rTSA patients. METHODS: Elderly patients with proximal humeral fracture who underwent primary rTSA within a year of fracture were identified in a national insurance database from 2005 to 2014. Patients were separated into acute (<4 weeks) or delayed (>4 weeks) cohorts based on the timing of rTSA. The univariate 1-year rates of revision and complication and surgery day cost of treatment were assessed. Multivariate logistic regression analysis was conducted, accounting for the factors of age, sex, obesity, diabetes comorbidity, and tobacco use. RESULTS: Four thousand two hundred forty-five (82.6%) acute and 892 (17.4%) delayed primary rTSA patients were identified. Acute rTSA was associated with a higher surgery day cost (acute $15,770 ± $8,383, delayed $14,586 ± $7,271; P < 0.001). Delayed rTSA resulted in a higher 1-year revision rate (acute 1.7%, delayed 4.5%; P < 0.001) and surgical complication rates of dislocation (acute 2.8%, delayed 6.1%; P < 0.001) and mechanical complications (acute 1.9%, delayed 3.4%; P = 0.007). Multivariate analysis identified delayed primary treatment as independently associated with increased risk of revision (odds ratio: 2.29, 95% confidence interval 1.53 to 3.40; P < 0.001) and dislocation (OR: 2.05, 95% confidence interval 1.45 to 2.86; P < 0.001). CONCLUSION: Delayed primary rTSA was associated with higher short-term rates of revision and dislocation compared with acute primary rTSA. Our results suggest that delaying rTSA, whether because of attempted nonsurgical treatment or patients' lack of access, may result in increased complication and additional surgery.
