Prior COVID-19 vaccination and reduced risk of cerebrovascular diseases among COVID-19 survivors.

The effects of COVID-19 vaccination on short-term and long-term cerebrovascular risks among COVID-19 survivors remained unknown. We conducted a national multi-center retrospective cohort study with 151 597 vaccinated and 151 597 unvaccinated COVID-19 patients using the TriNetX database, from January 1, 2020 to December 31, 2023. Patients baseline characteristics were balanced with propensity score matching (PSM).

Arthroscopic release for frozen shoulder: Does the timing of intervention and diabetes affect outcome?

Purpose: To evaluate the effect of timing of arthroscopic release and manipulation under anesthesia for frozen shoulder in patients with diabetes and non-diabetes.

Methods: One hundred and twenty-seven patients with frozen shoulder were included in the study. Each patient was assigned to: 1) one of four groups according to the duration from symptom onset to surgery (group A: ≤3 months; group B: 3-6 months; group C: 6-12 months; group D: >12 months), 2) diabetic or nondiabetic group.

Change in pitching biomechanics in the late-inning in Taiwanese high school baseball pitchers.

Repetitive overhead throwing may result in overuse injuries and a change in the pitching mechanics of a baseball pitcher. Accordingly, the purpose of this study is to quantify the changes in the muscle strength and pitching motion kinematics in the late-innings stage of a baseball game. Sixteen healthy baseball pitchers (16.

Underlying mechanisms of Tai-Chi-Chuan training for improving balance ability in the elders.

Objective: To compare balance ability between elderly individuals who practiced Tai-Chi-Chuan (TCC) for average 9.64 years and elderly individuals who did not practice TCC and its relationship with lower extremity muscle strength and ankle proprioception.

Methods: Twenty-five elderly volunteers were divided into two groups according to their TCC practcing experience.

Irreducible metatarsophalangeal joint dislocation of the lesser toes: a case report.

Irreducible metatarsophalangeal joint dislocation of the lesser toes is a rare injury. We present a 37-year-old man who was injured in a motorcycle accident and dislocated the first to third metatarsophalangeal joints and fractured the fourth metatarsal head. The left first metatarsophalangeal joint was reduced successfully through the closed method, but multiple attempts at closed reduction under local anesthesia failed to reduce the dislocated second and third metatarsophalangeal joints.

Arthroscopic transtibial single-bundle posterior cruciate ligament reconstruction using patellar tendon graft compared with hamstring tendon graft.

Purpose: The purpose of this study was to compare the outcomes of arthroscopic transtibial single-bundle posterior cruciate ligament reconstruction using autologous patellar tendon and hamstring tendon grafts.

Methods: From 1998 to 2007, 59 patients with symptomatic isolated posterior cruciate ligament injury were included in this retrospective study. Twenty-five knees were reconstructed using bone-patellar tendon-bone graft, and 34 knees were reconstructed using hamstring graft.

The effect of chinese yuanji-dance on dynamic balance and the associated attentional demands in elderly adults.

Walking performance changes with age. This has implications for the problem of falls in older adults. The aim of this study was to investigate the effects of Yuanji-Dance practice on walking balance and the associated attention demand in healthy elderly.

Patellar tendon ruptures in weight lifters after local steroid injections.

Introduction: Weight lifting is commonly associated with an increase in knee injury risk. Local steroid injection is thought to be associated with increased risk of spontaneous tendon rupture. The purpose of this report is to describe incidence of rupture of the patellar tendon after receiving multiple local steroid injections in weight lifters.

Treatment for frozen shoulder combined with calcific tendinitis of the supraspinatus.

Calcific tendinitis of the shoulder is a process that involves calcium deposition in the rotator cuff tendons. It is usually a self-limiting process and is often chronic in nature. However, it can lead to acute pain resulting in frozen shoulder syndrome.

Ulnar nerve palsy following fracture of the distal radius in an adolescent: a case report.

In adolescents, neurovascular injury, especially ulnar nerve injury, is rare with fracture of the distal radius. We present a 14-year-old boy who sustained fracture of the distal radius in his right wrist, who also had symptoms of ulnar nerve injury. Close reduction with percutaneous pinning and cast to fix the distal radius fracture was done immediately.

Angle analysis of Haglund syndrome and its relationship with osseous variations and Achilles tendon calcification.

Background: Haglund syndrome is a cause of posterior heel pain. The prominent posterosuperior projection into the retrocalcaneal bursa is thought to be a major etiology. Many methods have been proposed to measure the posterosuperior projection of the tuberosity into this bursa.

The results of articulating spacer technique for infected total knee arthroplasty.

In 19 patients with infected total knee arthroplasties, 21 knees were treated with debridement, component removal, and insertion of articulating spacer followed by second-stage total knee arthroplasty revision. A modified V-Y quadricepsplasty was to obtain adequate exposure in 6 cases. Average length of follow-up was 52.

Use of an external fixation combined with the buttress-maintain pinning method in treating comminuted distal radius fractures in osteoporotic patients.

Background: It is difficult to keep the alignment of a distal radius fracture in patients with osteoporosis and prevent malunion. Therefore, we hoped to design better method to maintain alignment.

Methods: Thirty-two patients over 65 years old with a displaced unstable distal radius fracture were treated by the external fixator combined with buttress-maintain pinning method and were compared with a group of 66 patients less than 60 years old treated by the same method.

Chondromalacia of trochlear notch after healing of olecranon stress fracture: a case report.

Introduction: Chondromalacia of the trochlear notch and stress fracture of olecranon are uncommon injuries in the throwing athletes.

Materials And Methods: We report an 18-year-old high school pitcher who had persistent postero-lateral elbow pain after a healed olecranon stress fracture of the right elbow. Diagnostic arthroscopy revealed chondromalacia of the trochlear notch.

Investigation of management models in elite athlete injuries.

This cross-sectional study investigated management models among elite athletes participating in sports including baseball, basketball, soccer, volleyball, tennis, softball, football, handball, track and field, swimming, judo, tae-kwon-do, gymnastics, archery, and weight lifting at the Tsoying National Sport Training Center. Data were collected by questionnaire. Of the 393 athletes investigated, 56% were male and 44% were female, with an average age of 20.

Revision of ankle arthrodesis.

From 1989 to 1996, we treated 18 cases (10 males, eight females; average age 48.2 years) of failed ankle arthrodesis by revision of ankle arthrodesis and followed their progress for at least two years. The average time interval between original surgery and revision was 17.

Langerhans cell histiocytosis of bone--a case report.

Langerhans cell histiocytosis of bone causes bone destruction and frequent bone reactions that mimic benign and malignant neoplasms as well as osteomyelitis. The bony lesion of Langerhans cell histiocytosis consists of histiocytes with variable numbers of eosinophils, lymphocytes, and neutrophils. We present a rare case of Langerhans cell histiocytosis of bone, including imaging studies and pathology.

Idiopathic frozen shoulder treated by arthroscopic brisement.

Arthroscopic brisement serves as an useful procedure in the treatment of idiopathic frozen shoulder. This series included 186 shoulders with a diagnosis of idiopathic frozen shoulder who had symptoms for an average of 8 months and failed conservative treatment of at least 12 weeks. Using the arthroscopic brisement (distension, debride, release and manipulation) to treat the idiopathic frozen shoulder, it is beneficial not only to detect the inside lesion but also a solution to the problem of stiffness.
