Regional Anesthesia for High-Risk Patients Undergoing Total Knee Arthroplasty: A Case Report.

Total knee arthroplasty (TKA) is a commonly performed surgery for individuals experiencing advanced knee osteoarthritis. Patients undergoing TKA can present with a variety of comorbidities, ranging from the absence of chronic illnesses to the presence of multiple health conditions. The complexity of these comorbidities can pose challenges in carrying out the desired procedure due to the elevated risk profile; this limits the anesthesia modalities that the physician can utilize.

The Outcomes and Revision Rate of Total Hip Arthroplasty in a Single Tertiary Center: A Retrospective Study.

Introduction Total hip arthroplasty (THA) is a commonly performed and successful orthopedic practice procedure. However, failure of arthroplasty may require revision THA and pose substantial clinical challenges for orthopedic surgeons. Therefore, this retrospective study aimed to estimate the revision rate of THA and its risk factors at a tertiary care hospital.

The Current Practice of Adult Idiopathic Scoliosis Surgical Treatment Among Spine Surgeons in Saudi Arabia.

Background: Scoliosis is a spinal deformity consisting of lateral curvature and rotation of the vertebrae. The goal of corrective scoliosis surgery is to restore alignment of the spine and maintain motion. However, there is no global agreement among spine surgeons on the best method of surgical intervention, and little is known about the variations in practice among spine surgeons in Saudi Arabia.

Background: Cervical spine injury is the most common vertebral injury after major trauma, 20% of all cervical fractures happen to be odontoid fractures. In young adults, odontoid fracture usually happens as a result of high-energy trauma after a motor vehicle accident (MVA). MVA in Riyadh represents 38.

Nonfunctional extradural thoracic spine paraganglioma in a pediatric patient: a case report.

Paraganglioma in the spine remains a rare occurrence that is mostly benign and commonly associated with other inherited symptoms. Presentation in the pediatric population is rare with a high risk of recurrence. This case reports an unusual presentation of a slowly progressing nonfunctional thoracic paraganglioma in a 6-year-old female child that presented with mass-related symptoms sparing the spinal canal.

One-year postoperative mortality rate among the elderly with hip fractures at a single tertiary care center.

Background: Hip fractures are one of the leading causes of disability and dependency among the elderly. The rate of hip fractures has been progressively increasing due to the continuing increase in average life expectancy. Surgical intervention is the mainstay of treatment, but with an increasing prevalence of comorbid conditions and decreased functional capacity in elderly patients, more patients are prone to postoperative complications.

Is it necessary to tie the medial row in rotator cuff repair double-row constructs when using suture tape?

Purpose: To evaluate the selected biomechanical differences of a double-row -osseous equivalent rotator cuff repair with a knotless versus knot-tying medial row using suture tape in regard to repair displacement, stiffness, and ultimate load to failure.

Methods: In 16 fresh-frozen human shoulders (8 matched pairs), double-row rotator cuff repairs were performed with medial-row mattress knots (MK) on one side, the other without (NK). Two DVRT (Differential Variable Reluctance Transducer) sensors were attached between the humerus and 3 mm above the repair site and were used to measure the displacement across the repair during cycling.

Postoperative Paralumbar Pseudoaneurysm: A Case Report.

Lumbar artery pseudoaneurysm is a rare adverse event that is presented in reports. It is associated with serious injuries such as in the retroperitoneal cavity and pelvis. Furthermore, infection and iatrogenic etiology were documented as well.

Anterior Cervical Discectomy and Fusion Complications and Thirty-Day Mortality and Morbidity.

Background Anterior cervical discectomy and fusion (ACDF) is a commonly used procedure. However, few studies reported post-operative complications. This study looks into the prevalence of possible complications and the mortality rate in the first 30 days postoperatively.

Severe heterotopic ossification post total knee arthroplasty in a patient with rheumatoid arthritis: a case report.

Stiffness following total knee arthroplasty (TKA) can be a devastating complication to the patient by limiting his function. Various causes have been reported in the literature, including heterotopic ossification (HO). HO is one of the rarely reported complication of TKA characterized by deposition of bone cells in non-skeletal tissue.

This study aimed to translate and adapt the Intermittent and Constant Osteoarthritis Pain questionnaire into the Arabic language and evaluate the validity and reliability of this scale for participants with knee or hip osteoarthritis. This questionnaire was translated based on the Manufacturers Alliance for Productivity and Innovation protocol. The test-retest reliability was calculated using the Intraclass Correlation Coefficient.

Adductor canal blockade versus continuous epidural analgesia after total knee joint replacement: A retrospective cohort study.

Background: Total knee arthroplasty is associated with intense pain postoperatively. Thus, adequate pain relief is essential in the immediate postoperative period to enable ambulation, initiation of physiotherapy, and prevention of postoperative complications. The objective of this study was to compare the effectiveness and early outcomes of adductor canal blockade (ACB) and continuous epidural analgesia (CEA) in patients who underwent a unilateral total knee replacement (TKR).

Myelofibrosis is a myeloproliferative disease that falls under a group of bone marrow malignancies known as myeloproliferative neoplasms. It manifests with splenomegaly, anemia, leukocytosis and, less commonly, bone pain. Ruxolitinib, Janus kinase inhibitor, has been shown to increase survival, to improve symptoms and has the potential to decrease osteosclerotic changes.

Filling Open Screw Holes in the Area of Metaphyseal Comminution Does Not Affect Fatigue Life of the Synthes Variable Angle Distal Femoral Locking Plate in the AO/OTA 33-A3 Fracture Model.

Introduction: The aim of this study is to evaluate the biomechanical effect of filling locking variable angle (VA) screw holes at the area of metaphyseal fracture comminution in a Sawbones® (Sawbones USA, Vashon, Washington) model (AO/OTA 33A-3 fracture) using a Synthes VA locking compression plate (LCP) (Depuy Synthes, Warsaw, Indiana).

Materials And Methods: Seven Sawbones® femur models had a Synthes VA-LCP placed as indicated by the manufacturers technique. A 4cm osteotomy was then created to simulate an AO/OTA 33-A3 femoral fracture pattern with metaphyseal comminution.

Novel technique for a symptomatic subscapularis herniation through a scapu-lar defect.

Fractures of the scapula are rare and have been reported to account for only 1% of all fractures and 3%-5% of upper extremity fractures. Several studies have reported successful outcomes with non-operative treatment of scapula fractures. Although non-operative treatments are successful in a very high percentage of patients, very few cases of non-union of scapular body fractures have been reported.

Biomechanical Analysis of All-Inside, Arthroscopic Suture Repair Versus Extensor Retinaculum Capsulorrhaphy for Triangular Fibrocartilage Complex Tears With Instability.

Purpose: To assess ulnocarpal joint stability after treatment of a peripheral triangular fibrocartilage complex (TFCC) injury with all-inside arthroscopic suture repair (SR), extensor retinaculum capsulorrhaphy with the Herbert sling (HS), and a combination of both (SR+HS).

Methods: Twelve fresh-frozen, age-matched, upper-extremity specimens intact from the distal humerus were prepared. Nondestructive mechanical testing was performed to assess native ulnocarpal joint stability and load-displacement curves were recorded.
