The study used data from an online survey of Nigerian HCWs ages 18 and older conducted in July 2021. Multivariate logistic regression analyses were conducted to examine predictors of getting two doses of a COVID-19 vaccine.

Osteochondritis dissecans of the glenoid: an analysis of grades, treatment, and outcomes.

Background: Osteochondritis dissecans (OCD) is an idiopathic disorder of subchondral bone that causes focal articular cartilage disruption with the potential long-term consequence of premature osteoarthritis. Glenoid OCD is exceedingly rare. This case series aims to identify the grades of glenoid OCD and report its grade-specific treatment with clinical, radiological, and functional outcomes.

Latissimus Dorsi Tear in an Olympics-Level Tennis Player: Case Report and Review of Literature.

Latissimus dorsi tears are extremely rare and are encountered primarily in high-level athletes. Noted initially in baseball pitchers, cases have been described in other sports too, with one report of a latissimus dorsi tear at the muscle-tendon junction in a tennis player. Anecdotal outcomes have been comparative after both non-operative and operative treatments.

Badminton Injuries in Elite Athletes: A Review of Epidemiology and Biomechanics.

Badminton is a popular sport in India and with multiple medal prospects will be closely followed at the Tokyo 2020 Olympics. Considered the fastest of the racquet sports, players require aerobic stamina, agility, strength, speed, and precision, besides requiring good motor coordination and complex racquet movements. Injuries in badminton are common despite it not being a contact sport, and include overuse injuries, and acute traumatic events.

Injuries in Cricket.

Context: Cricket is a popular global sport that requires a combination of physical fitness, skill, and strategy. Although a noncontact sport, overuse and impact injuries are common since players engage in a wide range of physical activities, including running, throwing, batting, bowling, catching, and diving. Significant or match time-loss injuries are defined as those that either prevent a player from being fully available for selection in a major match, or during a major match, cause a player to be unable to bat, bowl, or keep wicket when required by either the rules or the team's captain.

Knee Dislocations in Sports Injuries.

Knee dislocations are devastating when they occur on the athletic field or secondary to motor sports. The complexity of presentation and spectrum of treatment options makes these injuries unique and extremely challenging to even the most experienced knee surgeons. An astute appreciation of the treatment algorithm is essential to plan individualized management since no two complex knee dislocations are ever the same.

The Effect of Disinfectants and a Surface Wetting Agent on the Wettability of Elastomeric Impression Materials: An In Vitro Study.

Background: This study was carried out to evaluate the effect of two commercially available chemical disinfectants namely sodium hypochlorite and glutaraldehyde and a surface wetting agent on the wettability of three high precision elastomeric impression materials, addition silicone, condensation silicone and polyether.

Materials And Methods: Three different types of elastomeric impression materials commonly used in prosthodontic practice were selected. The glutaraldehyde and sodium hypochloride solutions were employed to disinfect the impressions made with the above-mentioned elastomeric impression materials.

Clinical Outcomes of Modified Mason-Allen Single-Row Repair for Bursal-Sided Partial-Thickness Rotator Cuff Tears: Comparison With the Double-Row Suture-Bridge Technique.

Background: Various repair techniques have been reported for the operative treatment of bursal-sided partial-thickness rotator cuff tears. Recently, arthroscopic single-row repair using a modified Mason-Allen technique has been introduced.

Hypothesis: The arthroscopic, modified Mason-Allen single-row technique with preservation of the articular-sided tendon provides satisfactory clinical outcomes and similar results to the double-row suture-bridge technique after conversion of a partial-thickness tear to a full-thickness tear.

Apical Closure of Nonvital Permanent Teeth: 15 Months Follow-up Study of Four Cases.

Obtaining a complete seal of the root canal system is a major problem in performing root canal treatment in nonvital teeth with incomplete root development and wide open apices. The aim was to study apexification using mineral trioxide aggregate (MTA), clinically and radiographically over a period of 15 months. MTA was used in four cases of teeth with incomplete root development in order to achieve an apical seal and the remaining canal was obturated with gutta-percha.

Postencephalitic bilateral heterotopic ossification of the hip in a pediatric patient.

Heterotrophic ossification has been defined as abnormal formation of mature lamellar bone in soft tissues. Neurogenic heterotopic ossification has been well described in adults. However, it is uncommon in the pediatric population, where it has been noted to recede in some cases.

Background: To investigate and compare the post-obturation pain after one-visit and two-visit root canal treatment in non-vital anterior teeth.

Materials & Methods: One hundred forty eight patients requiring root canal therapy on permanent anterior non-vital teeth with single root were included in this study. Patients were randomly assigned to either the one-appointment or the twoappointment group.

Correlation of posterior tibial slope with metaphysio-diaphyseal angle in total knee arthroplasty: A radiological study.

Background: Posterior tibial slope (PTS) is an important factor affecting postoperative range of motion (ROM) following total knee arthroplasty (TKA). Metaphysio-diaphyseal angle (MDA) is a new entity defined as angle between proximal anatomical axis and metaphyseal axis of tibia. This study was undertaken to determine PTS in Indian patients and find its correlation with MDA of tibia.

Orthogonal radiographic technique for radiographic visualization of coracoid process fractures and pericoracoid fracture extensions.

Radiographic visualization of coracoid process fractures is difficult due to the complex and variable 3-dimensional orientation of coracoid pillars. Failure to suspect an injury on preliminary radiographs has been described as a major reason for suboptimal management of these fractures. We describe a standardized method of patient positioning and radiographic beam angulation (orthogonal radiographic technique), to provide two roentgenographic views (Bhatia views) for visualization of individual coracoid pillars.
