RESUMO

BACKGROUND AND OBJECTIVES: Surgical resection with microscopically negative margins constitutes one of the key elements of a curative therapeutic approach for localized sarcomas. However, the prognostic value of quantitative margin width remains controversial. We sought to determine the prognostic significance of margin status and margin width for local recurrence (LR), distant recurrence (DR), and overall survival. METHODS: Retrospective analysis of 210 patients undergoing resection of localized sarcoma between 1997 and 2018 at a national sarcoma reference center. RESULTS: Logistic regression did not reveal an effect of metric margin width as a prognostic factor for LR (odds ratio [OR] = 0.98, p = 0.574), DR (OR = 1, p = 0.908), or overall survival (hazard ratio = 0.98, 95% confidence interval = 0.73-1.20, p = 0.609). Subgroup analysis revealed no differences between complete first resections (R0) and re-resections (re-R0) following unplanned R1-resections for LR (p = 0.727) and overall survival (p = 0.125), but a significantly higher DR-rate in re-R0 cases (p = 0.022). CONCLUSIONS: Achieving a negative margin is essential in sarcoma surgery, however, metric margin width was not associated with disease-specific outcomes. Re-resection of unplanned R1-resections should be performed to control for LR and overall survival rates. As re-R0 cases were at significantly higher risk of DR, these patients should be followed up closely in standardized surveillance protocols.

RESUMO

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most common reason for implant failure in arthroplasty. Surgical therapy is essential but there is no standardized guideline to determine infection eradication in multiple-step revision surgery. To date, clinical and laboratory inflammation markers and preoperative arthrocentesis are controversial to evaluate the infection status before reimplantation and therefore are often combined. Drain fluid cultures enable a microbiological analysis without need for further invasive procedure after revision surgery. This retrospective study evaluates the diagnostic performance of drain fluid cultures in diagnosing infection persistence according to the MSIS definition of PJI. METHODS: Drain samples have been taken after every revision surgery for microbiological testing. Afterwards, the results have been assigned to the infection status according to the diagnostic criteria of the MSIS definition of PJI. RESULTS: 1084 revision surgeries in 183 patients have been included, resulting in a total sample size of 1552 drain fluid cultures. Overall sensitivity was 36.0%, specificity was 90.7% and ROC-AUC was 0.63. CONCLUSION: Due to a high specificity and a low sensitivity drain fluid cultures can rule in but cannot rule out infection persistence in PJI.

RESUMO

Diagnosis and Therapy of Acute Achilles Tendon Ruptures Abstract. Acute Achilles tendon ruptures are a common pathology and often affect young athletic patients. Diagnosis is mostly clinical and by ultrasound. Conservative and operative treatment algorithms exist. The result of the treatment is mostly influenced by the elongation of the tendon during healing. Operative procedures tend to lead to less elongation but have a complication risk. After-treatment should be functional to reduce complication rate and faster rehabilitation. Treatment results are good in general, but some weakness is often found on the injured side.

RESUMO

There is no clear recommendation for wound closure material in foot and ankle surgery. Thus, we hypothesized that there was no difference in clinical outcomes among 3 suture materials, namely, absorbable sutures, nonabsorbable sutures, and metallic staples. This study compared the 3 materials for wound closure in foot and ankle surgery. In this prospective randomized study, 124 patients were randomly divided into the nonabsorbable suture group, absorbable suture group, and staple group. ASEPSIS score, Hollander Wound Evaluation Scale, and numerical rating scale (regarding pain and satisfaction) were collected at first dressing changes, suture removal, and 6 weeks after surgery. Suture time and incision length were recorded. No significant differences were detected for the ASEPSIS and Hollander Wound Evaluation Scale scores. There was significantly more pain after 6 weeks in the nonabsorbable suture group. The closure time (13 s/cm) with staples was significantly lower in the nonabsorbable suture group than in the other groups. Regardless of wound closure material, male sex and obesity appeared to be associated with a higher risk for the occurrence of wound complications. The 3 suture materials showed no significant differences regarding the frequency of wound complications. Staples and absorbable sutures should therefore be considered in the repertoire of suture materials used in foot and ankle surgery.

RESUMO

BACKGROUND: The common treatment for end-stage tarsometatarsal (TMT) arthritis is an arthrodesis of the affected joints. This study was performed to examine the clinical and radiographic outcome after TMT arthrodesis and to identify risk factors for postoperative complications. METHODS: A total of 101 patients with tarsometatarsal arthritis of at least 2 joints were retrospectively examined. Data were acquired using clinical and radiographic examination, pedobarographic analysis, and standardized questionnaires, including the European Foot and Ankle Society Score, the Foot and Ankle Outcome Score, a pain numeric rating scale (NRS), the 36-Item Short Form Health Survey, and the University of California at Los Angeles Activity (UCLA) Score. The fixation technique, any complications, and revision surgery were recorded. RESULTS: All scores improved significantly, except for the UCLA Score. The mean pain NRS score was significantly reduced from 7.7 preoperative to 3.0 postoperative (P < .05). The overall nonunion rate was 12.6%. Compared with 2 crossed-screw fixation, locking plate plus compression screw fixation was associated with a decreased nonunion rate (odds ratio [OR] 0.165, 95% confidence interval [CI] 0.032-0.854; P = .017). A body mass index >27 was significantly associated with a higher nonunion rate and wound healing problems (OR 12.05, 95% CI 1.430-101.468; P = .006; OR 5.03, 95% CI 1.273-19.871; P = .013). The overall reoperation rate was 25.2%. CONCLUSION: TMT arthrodesis of the medial and central column resulted in significant improvement in foot function and pain. A major complication was nonunion. Locking plate plus compression screw fixation was associated with a lower nonunion rate. LEVEL OF EVIDENCE: Level III, comparative series.
