- Use of closed suction drainage after primary total hip arthroplasty: a prospective randomized controlled trial(2018) FAGOTTI, Lorenzo; EJNISMAN, Leandro; MIYAHARA, Helder de Souza; GURGEL, Henrique de Melo Campos; CROCI, Alberto Tesconi; VICENTE, Jose Ricardo NegreirosABSTRACT Objective: This study aimed to investigate drain use in a controlled population of patients with hip osteoarthritis undergoing primary total hip arthroplasty. Methods: This prospective controlled trial evaluated 93 patients randomized into two groups: a group that received drains and a group that did not. The patients who were randomized to the drain group used a 3.2 mm drain placed under the fascia that was kept in place for 24 h. Postoperative evaluations were performed after 24 h and then three, six, and 12 weeks after total hip arthroplasty. The primary outcome was perioperative blood loss in both groups 24 h after total hip arthroplasty. The other parameters that were evaluated included mid-thigh circumference, the rate of blood transfusion, hematocrit, inflammatory serum levels, and the Harris Hip Score. Results: The clinical and laboratory data revealed no differences between the study groups with respect to blood loss and need for blood transfusion, duration of hospital stay, reoperation rate, complications, inflammatory serum markers, and the Harris Hip Score. Patients without closed suction drainage reported higher pain levels after 24 h (VAS score 1 vs. 2, p < 0.01). Conclusion: Similar clinical and laboratory outcomes were found in both cohorts.
- TWO CLASSIFICATIONS FOR SURGICAL WOUND HEMATOMA AFTER TOTAL HIP REPLACEMENT(2018) FAGOTTI, Lorenzo; EJNISMAN, Leandro; GURGEL, Henrique de Melo Campos; MIYAHARA, Helder de Souza; CROCI, Alberto Tesconi; VICENTE, Jose Ricardo NegreirosObjective: To determine the reliability of two classification methods for wound hematoma after total hip replacement. Methods: This prospective cohort study was conducted on patients who underwent total hip replacement for hip osteoarthritis between May 2014 and April 2015. Epidemiological, surgical, and functional data were assessed. Two experienced hip surgeons evaluated 75 pictures of wounds taken 24 hours after surgery. Both evaluators performed the analysis twice, with a 6-week interval between the two analyses. The subjective classification was divided into four different categories describing the hematoma: absent, mild, moderate, and severe. The objective classification was derived from mathematical calculation of the area of the hematoma using a grid superimposed on a picture of the wound. Results: The subjective classification demonstrated an intra-rater agreement of more than 70%, while kappa values showed poor to moderate inter-rater reliability. The objective classification based on mathematical measurements of the hematoma area was more reliable, with good to excellent intra-and inter-rater reliability. Conclusion: The objective classification demonstrated higher intra-and inter-rater reliability. The classification methods used in this study could serve as a useful instrument for orthopedic surgeons, researchers, and health care providers when assessing wound hematomas after total hip replacement.
- A modified iliofemoral approach to intrapelvic acetabular revision - technical note(2018) VICENTE, José Ricardo Negreiros; MIYAHARA, Helder de Souza; EJNISMAN, Leandro; SOUZA, Bruno de Biase; GURGEL, Henrique Melo; CROCI, Alberto TesconiABSTRACT Among the patterns of acetabular osteolysis associated with acetabular loosening, the authors emphasize the severity of pelvic dissociation and medial segmental losses in which the quadrilateral lamina is severely affected. Such lesions are potentially lethal in cases of large vascular injury. This note aimed to describe a modified iliofemoral approach in cases of massive intrapelvic migration of the acetabular component in patients with total proximity of the iliac vascular bundle and absence of an anatomical demarcation plane between the migrated contents and the iliac bundle. This approach was performed in 12 of 21 patients who had these criteria.
- Total hip arthroplasty using a posterior minimally invasive approach - results after six years(2015) VICENTE, José Ricardo Negreiros; MIYAHARA, Helder Souza; LUZO, Carlos Malheiros; GURGEL, Henrique Melo; CROCI, Alberto TesconiOBJECTIVE: To evaluate the medium-term clinical-functional results (minimum follow-up of six years) from total uncemented hip arthroplasty performed by means of a posterior minimally invasive access, in comparison with the traditional right lateral access. METHODS: In a comparative prospective study, 224 adult patients underwent elective total hip arthroplasty due to a diagnosis of primary or secondary osteoarthrosis. A group of 103 patients with posterior minimally invasive access was compared with a group of 121 patients with the traditional right lateral access. The mean length of follow-up among the patients of this sample was 7.2 years. We evaluated the clinical-functional and radiographic results and occurrences of loosening, along with any complications that occurred, with a minimum follow-up of six years. RESULTS: The clinical-functional analyses before the surgical procedure and six years afterwards were similar in the two groups (p = 0.88 and p = 0.55). One patient in the minimally invasive group underwent revision of the acetabular component and two patients in the control group underwent the same procedure (p = 0.46). The Trendelenburg clinical test, which showed weakness of the hip abductor musculature, was present in five patients operated using the traditional lateral route and absent in all those who underwent the minimally invasive procedure (p = 0.06). There was no difference regarding the radiographic parameters obtained, either in acetabular or in femoral positioning (p = 0.32 and p = 0.58). CONCLUSIONS: The medium-term clinical and radiographic results and the complication rates were similar between the patients who underwent total hip arthroplasty by means of the posterior minimally invasive access and those with the traditional lateral access.
