RESUMO

PURPOSE: The purpose was to compare perioperative outcomes of patients who underwent general or regional anesthesia for intramedullary (IM) nailing of tibial shaft fractures (TSFs). METHODS: Retrospective chart review was performed on a consecutive series of low-energy TSF patients who presented to a single academic medical center and a level 1 trauma center who underwent operative repair with a reamed IM nail. Collected information included demographics, injury information, anesthesia type (general or regional i.e. peripheral nerve block), intra-operative opiate consumption (converted to morphine milliequivalents [MME], and post-operative pain visual-analog scale [VAS] pain scores. Patients were divided into 3 groups based on the type of anesthesia received and univariate analysis was performed to compare the 3 groups. RESULTS: Seventy-six patients were included, with an average age of 44.47±16.0 years. There were 38 (50 %) who were administered general anesthesia and 38 (50 %) who were administered regional anesthesia in the form of a peripheral nerve block. There were no differences between the groups with respect to demographics, medical co-morbidities, rate of open fractures or AO/OTA fracture classification. Regional anesthesia patients received less intra-operative MME than general anesthesia patients (17.57±10.6, 28.96±13.8, p < 0.001). Patients who received regional anesthesia also spent less time in the operating room, received less MME on post-operative day 1, and ambulated further on post-operative day 1, however none of these differences were statistically significant. There were no cases of missed post-operative compartment syndrome or complications related to the administration of the peripheral nerve block. CONCLUSIONS: Regional anesthesia in TSF surgery received less intra-operative opioid requirements, without any untoward effects. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

PURPOSE: To determine when patients return to work following operative repair of tibial shaft fractures (TSF) and what risk factors are associated with a delayed return to work (RTW), defined as greater than 180 days after operative repair. METHODS: Retrospective chart review was performed on a consecutive series of TSF patients who underwent operative repair. Time to RTW was based on documented work-clearance communications from the operating surgeon. Patients were divided into 3 groups based on when they returned to work: early (≤ 90 days), average (91-80 days), and late (≥ 180 days). Univariate analysis was performed, and significant variables were included in multinomial logistic regression. RESULTS: There were 168 patients identified. Eighteen were excluded (retired, unemployed, or never returned to work) leaving 150 patients. The average time to RTW for the overall study population was 4.17 ± 2.06 months. There were 39 (26.0%) patients in the early RTW group, 85 (56.7%) in the average RTW group, and 26 (17.3%) in the late RTW group. Patient with high-energy injuries (p = 0.024), open fractures (p = 0.001), initial external-fixation (p = 0.036), labor-intensive job (p = 0.018) and post-operative non-weight bearing status (p = 0.023) all had significantly longer RTW. Multinomial logistic regression including these parameters found a closed fracture was associated with a 1.9 decreased risk of delayed RTW (p = 0.004, 95% CI 0.039-0.533). CONCLUSIONS: Open fractures, initial external-fixation, restricted post-operative weight-bearing and labor-intensive jobs are associated with a delayed RTW following operative repair of TSFs. LEVEL OF EVIDENCE: Therapeutic Level III.

RESUMO

Osteochondral lesions (OCL) of the knee are a common pathology that can be challenging to address. Due to the innate characteristics of articular cartilage, OCLs generally do not heal in adults and often progress to involve the subchondral bone, ultimately resulting in the development of osteoarthritis. The goal of articular cartilage repair is to provide a long-lasting repair that replicates the biological and mechanical properties of articular cartilage, but there is no widely adopted technique that results in true pre-injury state hyaline cartilage. Current treatment modalities have seen reasonable clinical success, but significant limitations remain. Microfracture provides short-term benefit with a fibrocartilage-based repair. While osteochondral autograft or allograft and autologous chondrocyte implantation can be effective, each have their strengths and shortcomings. Emerging concepts in cartilage repair, including scaffold engineering and one stage cell-based options, are continually advancing. These have the benefits of reduced surgical morbidity and potentially improved integration with surrounding articular cartilage but have not yet reached widespread clinical application. Tissue engineering strategies and gene therapy have the potential to advance the field, however, they remain in the early stages. The current article reviews the structure and physiology of articular cartilage, the strengths and limitations of present treatment modalities, and the newer ongoing innovations that may change the way we approach osteochondral lesions and osteoarthritis.

RESUMO

PURPOSE: The aim of this study is to evaluate 90-day outcomes and complications following radial head arthroplasty (RHA) for Mason Type III and IV radial head fractures (RHFs) and determine factors predisposing patients to early complications and revision surgery. METHODS: Patients undergoing RHA for Mason Type III and IV RHFs were identified retrospectively from an institutional database. Postoperative complications, reoperations, elbow range of motion, radiographs and concomitant injuries on the ipsilateral upper extremity were reviewed. Additionally, injuries were sub-classified as low-energy trauma (LET) or high-energy trauma (HET). Univariate logistic regression was performed to evaluate the risk for complications using patient factors not limited to the presence of concomitant ligamentous or bony injuries. P values < 0.05 were considered statistically significant. RESULTS: Seventy four patients were included in our study with an average follow-up time of 12.7 months. Complications within 90-days of operation occurred in 8.1% of patients: heterotopic ossification (4.1%), superficial wound dehiscence (2.7%), and posterior interosseous nerve palsy (1.4%). No patients required readmission or revision surgery in the 90-day postoperative period. Univariate regression analysis did not demonstrate a significant association between diabetes, ASA status, HET versus LET, or the presence of concomitant injury. Concomitant injuries were found in 92% of patients. CONCLUSION: Radial head arthroplasty for RHFs demonstrates a low complication rate in the short-term. Diabetes, ASA class, high versus low energy trauma, and presence of concomitant injury were not found to be associated with higher complication rates in the 90-day postoperative period. LEVEL OF EVIDENCE: Level of evidence IV, retrospective case series.
