Impact of Preoperative Quality of Life and Related Factors on the Development of Surgical Site Infections Following Primary Total Joint Arthroplasty: A Prospective Case-Control Study with a Five-Year Follow-Up.

Introduction: As surgical site infections (SSIs) after joint arthroplasty contribute to increased morbidity and mortality, they require further surgical intervention, prolonged hospitalisation, and antimicrobial treatment. The aim of our study is to examine the association between preoperative quality of life (QoL) and other predictive factors on the development of SSIs after primary arthroplasty. Methods: This is a prospective study that enrolled 56 patients with hip and knee primary osteoarthritis who underwent joint replacement. Data were collected from January to March 2017, including patient demographic characteristics, comorbidities, laboratory results, and perioperative clinical data. The patients' QoL was evaluated preoperatively by applying the knee injury and osteoarthritis outcome score (KOOS) and the hip disability and osteoarthritis outcome score (HOOS) for total knee replacement (TKR) and total hip replacement (THR), respectively. A 5-year follow-up was conducted to assess the clinical status of the patients. Results: 66.1% of patients underwent TKR, with 4.9 ± 1.2 days of hospitalisation, 16% of them required autologous blood transfusion, while 33.9% of patients were treated with THR, with 5.7 ± 1 days hospitalisation and 36.8 of them required this type of transfusion. 16 patients were diagnosed with SSIs, with the older of them (>65 years old) presenting lower probability (odds ratio: 0.13, 95% CI: 0.03-0.62) requiring treatment with additional antibiotics, while revision surgery was performed in 3 of these cases, following periprosthetic joint infection (PJI). Overall preoperative QoL was not statistically associated with SSIs, but low QoL scores were associated with higher rates of SSIs and increased levels of postoperative pain (p = 0.009 < 0.05). Conclusions: The duration of each operation (>90 min), the length of hospitalisation (>4 days), and the presence of comorbidities including hypothyroidism and recurrent urinary tract infections were associated with a high risk for SSIs following arthroplasties. On the contrary, this study revealed no association between other comorbidities, including heart coronary disease, hypertension, and diabetes mellitus, with close monitoring of plasma glucose and SSIs. Moreover, the younger the patients, the more likely they were to require treatment with antibiotics. Overall, high QoL index scores were mainly accompanied by low rates of postoperative SSIs and pain.

Operative treatment of athletic pubalgia in competitive athletes: a retrospective study.

BACKGROUND: Athletic pubalgia is an obscure sport injury, presenting mainly with groin pain during twisting movements. The present 15 year study reports outcomes, intraoperative findings and complications of the endoscopic surgical treatment in competitive athletes. METHODS: All competitive athletes, from 2004 to 2018, suffering from athletic pubalgia, treated with laparoscopic Total Extra-Peritoneal technique, at the Department of General, Laparoscopic, Oncologic and Robotic Surgery of the Athens Medical Center were included in this retrospective cohort. Postoperative pain, complications, return to previous training routine and patients' satisfaction were evaluated. RESULTS: A total of 130 patients (115; 88.5% males and 15; 11.5% females) with a mean age of 26.7±7.5 years were evaluated. Preoperatively, mean numeric scale pain was found to be 7.7±1.7. Three days postoperatively, the mean numeric pain scale was 3.4±1.5, showing 55.8% decrease. The mean time for return to sports activity was found to be 6.27±3.02 weeks. Regarding complications, six patients (4.6%) had slight numbness at the groin area during the first 6 postoperative months and one patient (0.8%) suffered from a postoperative hematoma. No recurrence was observed. At the final follow-up (mean 76.58±46.5 months), a total of 97 (74.7%) patients were very satisfied, 31 (23.8%) satisfied and two (1.5%) not satisfied with the outcome. CONCLUSIONS: Laparoscopic operative treatment in competitive athletes suffering from athletic pubalgia seems to offer rapid recovery, rapid return to sports, as well as very low complications rate and no recurrence.

Truncal Changes in Patients After Total Hip or Knee Arthroplasty: A Surface Topography Study.

Introduction Total hip and knee arthroplasty (THA/TKA) are among the most successful orthopedic operations performed, aiming at the alleviation of osteoarthritic pain. This report is a surface topography study that assesses the mechanism by which THA or TKA influences truncal parameters. This study represents the first time that surface topography has been used for the assessment of truncal parameters. Methods In total, 15 patients with THA, including nine women and six men, with a mean age of 65.07 ± 9.73 years (range: 47-80 years), and 23 patients with TKA were assessed preoperatively and four and 12 months postoperatively. These patients were also compared with a control group (CG) that included 25 individuals, including 12 women and 13 men, with a mean age of 69.28 ± 10.11 years (range: 55-86 years). The Diers Formetric four-D analysis system was used to calculate several truncal parameters in all planes. Results Data analysis revealed statistically significant differences in the kyphotic angle (°; 56.50→63.57, p < 0.05) and the pelvic obliquity (°; 3.40→1.93, p < 0.05) between measurements at baseline and 12 months after THA. Statistically significant differences were noted for the pelvic obliquity (°; 2.74→1.43, p < 0.05) between measurements at baseline and 12 months after TKA. Conclusions THA and TKA are causes of truncal morphological alterations. THA and TKA improved pelvic obliquity, contributing to correct the posture in the patients.

Depressive mood in individuals with spinal cord injury (SCI) living in Greece.

STUDY DESIGN: Cross-sectional study. OBJECTIVES: To provide data on depressive symptoms rates in the Greek SCI population and to investigate their association with demographic and clinical variables. SETTING: Greek territory. METHODS: One hundred and sixty-four individuals with SCI living in the community for at least 1 year after the completion of the primary inpatient rehabilitation program were included in the study. Our group of participants were enrolled from multiple rehabilitation centers throughout Greece and were evaluated for probable depression according to the Patient Health Questionnaire (PHQ-9). Univariable and multiple linear regression analyses were performed to assess the possible association of risk factors with the occurrence of depression. We had also examined the correlation between PHQ-9 and scales measuring social reintegration (Craig Handicap Assessment and Reporting Technique (CHART)), quality of life (World Health Organization Quality of Life BREF (WHOQOL-BREF)), and independence (Spinal Cord Independence Measure (SCIM)). RESULTS: It was found that 18.2% of the sample had probable depression. The mean (SD) PHQ-9 score was 5.7 (4.9). The multiple linear regression analysis showed that high pain scores (P = 0.001) and suffering from both nociceptive and neuropathic pain (P = 0.005) were associated with depressive mood, while pressure ulcers had a significant effect (P = 0.049) only in the univariable analysis. Participant's PHQ-9 scores had also a negative correlation with almost all CHART, WHOQOL-BREF, and SCIM subscales' scores. CONCLUSIONS: This study documents relatively low rates of probable depression among individuals with SCI in Greece. Severe pain and pressure ulcers were the main identified predictors of depressive mood.

Percutaneous vertebroplasty in adult degenerative scoliosis for spine support: study for pain evaluation and mobility improvement.

We evaluate the efficacy-safety of percutaneous vertebroplasty (PV) as primary treatment in adult degenerative scoliosis. During the last 4 years, PV was performed in 18 adult patients (68 vertebral bodies) with back pain due to degenerative scoliotic spine. Under anaesthesia and fluoroscopy, direct access to most deformed vertebral bodies was obtained by 13G needles, and PMMA for vertebroplasty was injected. Scoliosis' inner arch was supported. Clinical evaluation included immediate and delayed studies of patient's general condition and neurological status. An NVS scale helped assessing pain relief, life quality, and mobility improvement. Comparing patients' scores prior to (mean value 8.06 ± 1.3 NVS units), the morning after (mean value 3.11 ± 1.2 NVS units), at 12 (mean value 1.67 ± 1.5 NVS units), and 24 months after vertebroplasty (mean value 1.67 ± 1.5 NVS units) treatment, patients presented a mean decrease of 6.39 ± 1.6 NVS units on terms of life quality improvement and pain relief (P = 0.000). Overall mobility improved in 18/18 (100%) patients. No complications were observed. During follow-up period (mean value 17.66 months), all patients underwent a mean of 1.3 sessions for facet joint and nerve root infiltrations. Percutaneous vertebroplasty in the inner arch seems to be an effective technique for supporting adult degenerative scoliotic spine.

External fixation as a primary and definitive treatment for tibial diaphyseal fractures.

The aim of this study was to evaluate the effectiveness of unilateral external fixator as primary and definitive treatment for open tibial fractures, fractures with severe soft tissues injuries, threatened compartment syndrome, and in multiply injured patients. Two hundred and twenty-three tibial shaft fractures (212 patients) were treated. In open fractures, union was achieved in 25 weeks, while in closed in 21. There were 18 nonunions, 21 delayed unions, 4 malunions, 58 pin infections and 3 osteomyelitis. A reoperation was performed in 42 patients. Fat embolism was diagnosed in three patients, pulmonary embolism in five and deep venous thrombosis in 14. The external fixator was definitive treatment in 87.27%. Unilateral external fixators can be used as primary and definitive treatment for complicated tibia shaft fractures. Re-operation or change of the method must be performed only when there is a delay in callus formation.

Influence of neurological level of injury in bones, muscles, and fat in paraplegia.

To investigate the influence of the neurological level of injury in bone mineral content (BMC) and mechanical properties, lean mass (LM), and fat mass (FM) among paraplegics with a similar duration of paralysis (DOP), we separated 30 paraplegics into group A (15 men, high-level paraplegia) and group B (15 men, low-level paraplegia) and compared them with group C (33 men, nondisabled). In all subjects, we measured stress-strain index (SSI) at 14% (SSI(2)) and 38% (SSI(3)) of the tibia length and the difference between them using peripheral quantitative computed tomography (XCT 3000 [Stratec Medizintechnik, Pforzheim, Germany]) and lower-limb BMC, LM, and FM (g) using whole-body dual-energy X-ray absorptiometry (Norland XR-36 [Norland Medical Systems, Inc; Fort Atkinson, Wisconsin]). Bone strength parameters, BMC, and LM were statistically decreased, but we found no difference in paraplegic FM compared with group C. We found a correlation between the DOP and the difference between SSI 3 and SSI 2 in group B (r = 0.53, p = 0.03 and r = 0.5, p = 0.04, respectively). We correlated DOP with FM in group A's lower limbs (r = 0.5, p = 0.05). Because of the nonsignificant DOP, the groups with paraplegia act differently in tibia mechanical properties and lower-limb body composition.

Body composition in paraplegic men.

To investigate alterations in the body composition of paraplegic men, 31 complete paraplegic men thoracic (T)4-T 12 neurological level of injury, 16 with paraplegia above (high), and 15 below (low) thoracic 7, were compared with 33 able-bodied men. Whole body dual X-ray absorptiometry was used to estimate regional (arms, legs) and total body bone mineral density (g/cm(2)), lean, and fat mass (g).The influence of the neurological level of injury and the duration of paralysis in relation with the above parameters were also investigated. Body mass index, bone mineral density, and lean mass were significantly decreased (p < 0.0005) and fat mass was increased (p < 0.05) in the legs and total body composition in paraplegics. Bone mineral density was significantly lower in high paraplegics' arms compared with low paraplegics (p = 0.028). The correlation of body mass index with fat mass was statistically significant in all paraplegics and controls (r = 0.57, p = 0.001 and r = 0.73, p = 0.0001, respectively) and in low paraplegics (r = 0.72, p = 0.004). Legs' bone mineral density and arms' fat mass were correlated with the duration of paralysis in all paraplegics (r = -0.46, p = 0.009 and r = 0.43, p = 0.020, respectively) and in high paraplegics (r = 0.73, p = 0.001 and r = 0.55, p = 0.042, respectively). Total fat mass was correlated with the duration of paralysis in high paraplegics (r = 0.5, p = 0.05). These results suggest body composition changes in paraplegics.
