Cross-Cultural Adaptation and Validation of the Arabic Version of the Harris Hip Score.

Background: The Harris Hip Score (HHS) questionnaire has been translated and validated into many languages including Italian, Portuguese, and Turkish but not Arabic. The goal of this study was to translate HHS into the Arabic language with cross-cultural adaptation to include and benefit Arabic speaking communities as it is the most widely used instrument for disease-specific hip joint evaluation and measurement of total hip arthroplasty outcome. Methods: This questionnaire was translated following a clear and user-friendly guideline protocol. The Cronbach's alpha was used to assess the reliability and internal consistency of the items of HHS. Additionally, the constructive validity of HHS was evaluated against the 36-Item Short Form Survey (SF-36). Results: A total of 100 participants were included in this study, of which 30 participants were re-evaluated for reliability testing. Cronbach's alpha of the total score of Arabic HHS is 0.528, and after the standardization, it changed to 0.742 which is within the recommended range (0.7-0.9). Lastly, the correlation between HHS and SF-36 was r = 0.71 (P < .001) which represents a strong correlation between the Arabic HHS and SF-36. Conclusions: Based on the results, we believe that the Arabic HHS can be used by clinicians, researchers, and patients to evaluate and report hip pathologies and total hip arthroplasty treatment efficacy.

Efficacy of interspace between the popliteal artery and the capsule of the posterior knee (iPACK) block versus periarticular local infiltration analgesia after unilateral total knee arthroplasty: Prospective randomized control trial.

OBJECTIVES: To compare the efficacy of interspace between the popliteal artery and the capsule of the posterior knee (iPACK) block with periarticular local infiltration analgesia (LIA) to assess postoperative pain control and enhanced recovery after total knee arthroplasty (TKA). METHODS: This research was carried out at King Saud University Medical City, Riyadh, Saudi Arabia, from September 2020 to March 2021. Eighty Patients scheduled for elective unilateral TKA were randomized to receive either iPACK or periarticular LIA along with adductor canal block under spinal anesthesia. The primary outcome was postoperative pain score, and secondary outcomes included physical rehabilitation, duration of surgery, length of post-anesthesia care unit stay, hemodynamics, and length of hospital stay. RESULTS: The pain score during activity in iPACK group was significantly lower compared to LIA group at 4 hours postoperatively, but no significant difference was observed at 24 or 48 hours. The timed up and go test took significantly longer for patients in LIA group at 4, 24, and 48 hours compared to those in iPACK group. No significant differences in knee range of motion were observed between the 2 groups at any point. CONCLUSION: Based on our findings, iPACK block is an effective technique in reducing pain in the immediate postoperative period without affecting motor function, resulting in enhanced recovery following primary TKA.

Students' satisfaction and continued intention toward e-learning: a theory-based study.

Coronavirus disease (COVID-19) has forced the urgent lockdown of schools and colleges worldwide. To ensure the continuity of education a shift from traditional teaching to e-learning was required. This study aims to identify factors that affect students' satisfaction and continued intention towards e-learning. A questionnaire was distributed to medical and dental students (second to sixth year) from different universities in Saudi Arabia. The study synthesizes the expectation-confirmation theory (ECT) and the theory of planned behavior (TPB) to predict students' satisfaction and intention to continue using e-learning using a validated self-administered questionnaire. We used the structural equation model to analyze the results and assess the study's hypotheses. A total of 870 completed questionnaires were received (67% response rate). The results showed that students were at a moderate level of satisfaction (median = 3.5). According to the ECT, both perceived usefulness and confirmation significantly influenced students' satisfaction (ß = -.69 and ß = .82, respectively). Satisfaction was the strongest predictor of students' continued intention (ß = 1.95). Among the TPB constructs, perceived behavioral control (ß = .51), attitudes (ß = .39), and subjective norms (ß = .36) had a significant positive influence on their intention to use e-learning. The results suggest efforts to increase students' satisfaction and intention with e-learning should be directed to adopting easy and useful e-learning platforms. In addition, training and motivating students to continue e-learning and increasing their confidence to ensure the effective and efficient use of such teaching modalities.

The smartphone inclinometer: A new tool to determine elbow range of motion?

BACKGROUND: There are easily accessible tools on smartphones (APP) for measuring elbow range of motion (ROM). The purpose of this study is to evaluate the validity of a particular APP in determining elbow ROM in comparison with the commonly used goniometer (GON), surgeon estimation of range (EST) and measurement on X-ray (XR). METHODS: The study included 20 patients (40 elbows). Flexion, extension, pronation and supination were measured using three different methods: EST, GON and APP. Radiographic measurements were taken using the average humeral diaphysis axis and dorsal midthird of ulna in flexion and extension. RESULTS: The accuracy of the three different methods has been compared to GON using statistical analysis (ANOVA and paired samples test). There was no statistically significant difference for XR flexion measurement (mean of 2.8° ± 1.5°). The APP overestimated flexion (mean of 6.4° ± 1.0°), and EST underestimated it (mean of - 7.9° ± 1.1°). For extension, the mean difference was 2.8° ± 0.7° for EST and - 26.8° ± 3.1° for XR. The APP method did not significantly differ from GON. Supination accuracy was greater with EST (2.7° ± 1.7°) than with APP (5.9° ± 1.9°). There was no difference for pronation measurement with both EST and APP. CONCLUSIONS: This study is the first comparing four measurement techniques of elbow ROM. Our results showed that EST was only accurate for forearm rotation. The XR scored the best for flexion but is less reliable for extension. Surprisingly, compared to GON, APP did not correlate as we expected for flexion and supination, but the other methods were also inaccurate. We found APP to be very useful to measure complete arc of motion (difference between maximal flexion and maximal extension). LEVEL OF EVIDENCE: III, Retrospective review of a prospective cohort of elbow fracture patients: Diagnostic Study.

Bilateral Simultaneous Quadriceps Tendon Rupture in a 24-Year-Old Obese Patient: A Case Report and Review of the Literature.

Introduction. Simultaneous bilateral quadriceps tendon ruptures (SBQTR) are uncommon knee injuries and most frequently occur in male patients, over 50 years of age. It can be associated with one or more predisposing risk factors like obesity, steroids use, and hyperparathyroidism. The main focus of this paper is to review SBQTR in obese patients. Case Report. We are reporting the youngest patient in the literature to date, a 24-year-old obese male patient, who presented to the emergency department complaining of bilateral knee pain and inability to walk after a fall during a basketball game. His clinical examination revealed the presence of a palpable suprapatellar gap and loss of knee extension bilaterally. Magnetic resonance imaging (MRI) confirmed that both of his quadriceps tendons were ruptured. A day after his diagnosis, the patient underwent successful operative repair followed by rehabilitation. At the two-year follow-up, the patient had full strength of both quadriceps muscles with no extension lag. Conclusion. The diagnosis of SBQTR can be challenging. Early diagnosis and treatment are associated with better functional outcome compared to delayed treatment. Physicians should have a high index of clinical suspicion in order not to miss such an injury and achieve favourable outcomes.

Acute revision hip arthroplasty: a previously unrecognized risk factor for heterotopic ossification.

BACKGROUND: The aim of this retrospective review was to determine the incidence and severity of heterotrophic ossification (HO) following acute revision total hip arthroplasty (THA), and whether this represents a significant risk factor for HO that should be treated prophylactically. MATERIALS AND METHODS: A total of seven patients (three men and four women) with a mean age of 55 years (39-70 years) who underwent a reoperation of their THA for any reason that required a hip arthrotomy within 3 weeks of their primary or revision THA were included, with a mean follow-up of 8.8 years (2-12 years). All patients were evaluated radiographically for any evidence of HO and clinically using the Harris Hip Score. RESULTS: All seven hips (100 %) developed HO, with 71 % being severe (Brooker III and IV HO). One hip (14 %) developed Brooker IV HO, four hips (57 %) developed Brooker III HO, and two hips (29 %) developed Brooker II HO. The patient's range of motion varied, but was very limited in three patients. Three patients (42.8 %) were not satisfied with their surgery; one patient had Brooker IV HO, and two patients had Brooker III HO. CONCLUSION: Acute reoperation after primary or revision THA is a significant risk factor for the development of extensive HO, which requires prophylactic treatment.

Incisor Diastasis Associated With Halo Traction in an Osteogenesis Imperfecta Patient: Case Report.

BACKGROUND: Scoliosis is a known manifestation of osteogenesis imperfecta (OI), which is characteristically severe in nature and interferes with the general health of these patients. Halo gravity traction (HGT) has been advocated as a preoperative treatment modality to ease the surgical risk while managing these patients with such fragile spines. Application of HGT to this patient population in itself carries a risk. PURPOSE: The authors report an unusual complication of transient incisor diastasis in a patient with OI and scoliosis who was placed in perioperative HGT as a stage of scoliosis management. RESULTS: The patient had a posterior instrumentation and spinal fusion for the scoliosis and the diastasis resolved after HGT removal. CONCLUSIONS: Although HGT is a valuable preoperative option in the management of scoliosis in OI patients, it is necessary to assess the patient frequently for both common and rare complications of this procedure.

Evaluation of the orthopedic residency training program in Saudi Arabia and comparison with a selected Canadian residency program.

OBJECTIVE: The primary aim of the present study was to assess the quality of the Saudi Orthopedic Residency Program. METHODOLOGY: As a comparator, a cross-sectional survey involving 76 Saudi residents from different training centers in Saudi Arabia namely; Riyadh, Jeddah, Medina, Abha, and Dammam and 15 Canadian. RESULTS: The results showed that Canadian residents read more peer-reviewed, scholarly articles compared with Saudi residents (P=0.002). The primary surgical role for residents was to hold retractors during surgery. The survey respondents strongly supported the ability to recommend removal of incompetent trainers. Saudi trainees were more apprehensive of examinations than Canadian trainees (P<0.0001). Most residents preferred studying multiple-choice questions before examinations. Saudi and Canadian participants considered their programs to be overcrowded. Unlike Canadian participants, Saudi trainees reported an inadequate level of training (P<0.0001). CONCLUSION: Educational resources should be readily accessible and a mentorship system monitoring residents' progress should be developed. The role of the resident must be clearly defined and resident feedback should not be ignored. Given the importance of mastering basic orthopedic operative skills for residents, meaningful remedial action should be taken with incompetent trainers.
