ABSTRACT
Background Lumbar disc herniation is considered the most common cause of sciatica, which is a contributing factor to disability. Surgical management of lumbar disc herniation in the form of discectomy is superior to conservative management in terms of better recovery and pain relief. However, recurrence, residual back pain, and disability are common expected complications following surgery. Therefore, this study aims to determine the prevalence of low back pain and its related risk factors and disability following discectomy at King Fahad Hospital in the Al-Ahsa region. Methodology A cross-sectional study was conducted at King Fahad Hofuf Hospital in the Al-Ahsa region among patients who were admitted and underwent lumbar spine discectomy in the last six years either due to traumatic or degenerative causes. The study used an anonymous questionnaire consisting of the patient's sociodemographic data, medical and surgical history, spine disease history, and surgical history. The preoperative Glasgow Coma Scale score, neurological status, and American Spinal Cord Impairment Scale score were noted. In addition, immediate postoperative neurological status and minor complications were recorded. Moreover, more than six months postoperatively, the Numeric Analogue Scale and the Oswestry low back pain disability index questionnaire were administered. Results A total of 201 patients were included in the study. The majority of the patients were male (59.7%), with ages ranging from 41 to 60 years (51.7). Most patients underwent one surgery (83.6%) in the form of discectomy alone (90.5%) at L3-L4 (58.7%), for which the intervertebral disc was the most common degenerative indication for surgery. All patients (100%) had low back pain preoperatively, and most patients (50.7%) had no back pain six months postoperatively. Preoperatively, 58.2% had diminished neurological status, while only 29.9% showed a deficit postoperatively. Postoperative low back pain was significantly associated with office-based jobs (p = 0.021, 60.5%) and a high number of surgeries (p = 0.004, 74.1%). The following factors were observed to be risk factors for having lower back pain: six months postoperatively, being unemployed (p = 0.024, odds ratio = 4.38, 338% increased risk), having an office-based job (p = 0.012, odds ratio = 3.98, 298% increased risk), and the underlying cause of the problem being degenerative (p = 0.003, odds ratio = 3.34, 234% increased risk). Low back pain-related severe disability postoperatively was significantly associated with increased age >40 (28-50%; p = 0.045), female gender (p = 0.012, 44.4%), and being unemployed (p = 0.002, 51.4%). The level of disability six months postoperatively was moderate in 40.4% of the patients. Conclusions Lumbar discectomy is a successful procedure for relieving low back pain among patients with degenerative spine disease, with an improvement that involves neurological status. However, residual back pain may still occur in less than half of the patients despite appropriate management, such as being unemployed or office-based employees and having multiple spine surgeries. However, low back pain-related disability is often moderate, with increasing severity seen with increased age, being female, and being unemployed.
ABSTRACT
Introduction One of the major psychological factors that can affect the outcome of hip arthroplasty is postoperative kinesiophobia, which is defined as a fear of movement. The effect of kinesiophobia and excruciating pain has not been widely explored in hip arthroplasty literature especially in Saudi Arabia. Aim This study aimed to investigate kinesiophobia and pain catastrophizing after total hip arthroplasty (THA) in King Fahad Hospital, Hofuf, Saudi Arabia. Materials and methods This is a retrospective cross-sectional study conducted at King Fahad Hospital, Hofuf, Saudi Arabia. Using a validated self-administered questionnaire, participants were questioned telephonically. Questionnaires included basic demographic characteristics, Tampa Scale of Kinesiophobia (TSK), and Numerical Analogue Scale (NAS). Data were tabulated in MS Excel and all statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Results Seventy-four patients were recruited (60.8% females vs 39.2% males). The TSK mean score was 40.7 (SD 8.88) while the mean NAS score was 5.45 (SD 2.79). The prevalence of kinesiophobia was 62.2%. The statistical test revealed that there was a statistically significant positive correlation between TSK score and NAS score (r=460; p<0.001). Furthermore, kinesiophobia was widely prevalent among patients who had avascular necrosis (p<0.001) and among those who underwent physiotherapy (p=0.044). Conclusion There was a high prevalence of kinesiophobia among patients who underwent THA. Pain intensity directly correlated with the presence of kinesophobia.
ABSTRACT
Background Patients with avascular necrosis related to sickle cell disease (SCD) can be severely disabled by the severe degenerative changes of their hip. Total hip arthroplasty (THA) remains the only surgical option for some of these patients. Total hip arthroplasty can be a challenging procedure, and SCD patients demonstrate high percentages of medical, intraoperative, and postoperative complications and implant failure. Furthermore, the need for THA following avascular necrosis in the Eastern Province of Saudi Arabia is high, and the subsequent risk of periprosthetic fracture is prevalent. Therefore, it is crucial to conduct such a study. Aim of the study This cross-sectional retrospective study aimed to assess the prevalence and associated risk factors for periprosthetic fractures during total hip arthroplasty in sickle cell disease patients at King Fahad Hospital Hofuf, Saudi Arabia. Methods We collected the data of all SCD patients who had undergone THA during the study period, January 2015 to September 2020. Forty-nine SCD patients who had undergone THA during the study period were included. Patients who had undergone hip hemiarthroplasty, postoperative fractures, or had an indication of THA other than avascular necrosis were excluded. Surgeon factors, assistant factors, and surgical technique were also excluded. We then analyzed the data according to gender, age, BMI, American Society of Anesthesiologists classification, implant fixation type, avascular necrosis stage, proximal femoral morphology, Vancouver classification type, sickle cell type, preoperative hemoglobin (Hb) level, and the risk of periprosthetic fractures. Descriptive statistics were presented using frequency and percentages for categorical variables, and continuous variables were summarized using means ± standard deviations. Independent t-tests and chi-square tests were used to test for associations between categorical variables. At 0.05, the significance level was set. Results Of the patients, 32.7% were male and 67.3% were female. 32.7% of the patients had advanced degenerative changes due to avascular necrosis. Among the patients, 20.4% had an intraoperative periprosthetic femoral fracture, 90% had a Vancouver classification class A, and 10% had a Vancouver classification class B1. According to Dorr classification, 75.5% were classified as Dorr A and 24.5% as Dorr B. Of the patients, 48 had an uncemented implant, and only 1 had cemented. The mean perioperative Hb was 9.02 + 2.02, with a minimum of 6 and a maximum of 14. No significant associations were found between the incidence of intraoperative femoral fracture and the demographic variables and the operative profile characteristics. However, a significantly higher rate of fracture was observed in patients operated on the right side compared to patients operated on the left side. Conclusion The prevalence of periprosthetic intraoperative fracture among SCD patients at King Fahad Hospital Hofuf was 20.4% during the study period. Even with adequate perioperative management, orthopedic surgeons must be prepared to deal with high rates of intraoperative fracture. No significant association was found between the incidence of intraoperative femoral fracture in SCD patients and the demographic variables and the operative profiles. However, a significantly higher rate of fracture was observed in patients operated on the right side compared to patients operated on the left side.
