Background: Pericapsular nerve group (PENG) block has shown effectiveness for acute hip pain associated with fractures and surgery. Herein, PENG block was performed for osteoarthritis (OA)-related chronic hip joint pain.

Case Presentation: A 65-year-old woman presented left hip pain. She had bilateral hip osteoarthritis that improved with medications; however, a fall resulted in left hip pain. She experienced severe pain on movements, which required walking aids. To alleviate the hip pain, a PENG block was performed under ultrasound guidance. Transient muscle weakness occurred in 2 of 5 times. After 5 blocks, she regained the ability to walk without assistive devices. Pain did not recur even after 6 months.

Conclusions: Repeated PENG blocks of short-acting local anesthetics alone could be an effective pain management technique for chronic hip pain. For safety, the appropriate injection site and local anesthetic dosage must be carefully considered.

Transient osteoporosis of the hip (TOH), also known as bone marrow edema (BME), is an uncommon condition of unknown etiology. While transient osteoporosis usually affects the hip, it could affect other joints as well. The most common presentation is pain and it has been linked to reduced bone mineral density.

Purpose: Our study aimed to present health-related quality of life (HRQL) after combined bone reconstruction in nonambulatory patients with cerebral palsy (CP) after at least a 2-year follow-up and to assess its impact on HRQL using the Caregiver Priorities and Child Health Index of Life with Disabilities questionnaire (CPCHILD) as the primary outcome measure.

Methods: In this prospective study, we analyzed 31 nonambulatory patients with spastic or mixed CP (GMFCS levels IV-V) who underwent hip reconstructive surgery between 2015 and 2021. The surgical procedures included one-sided varus derotation osteotomy of the femur with Dega transiliac osteotomy and, on the opposite side, varus derotation osteotomy (VDRO) of the femur with shortening and, as needed, Dega pelvic osteotomy.

Introduction: In this article, we report a unique case of head-stem dissociation in a metal-on-metal total hip replacement which utilized an Exeter stem. Although metallosis and pseudotumor formation are well recognized complications of metal-on-metal hip replacements, head-stem dissociations are rare with few being reported in literature. To the best of our knowledge, this case report is the first to report this occurrence in an Exeter stem.

Introduction: Total hip arthroplasty (THA) surgeries are rapidly increasing due to an aging population, leading to an increase in degenerative hip osteoarthritis. However, 1% of these patients go through prosthetic joint infection (PJI), which gives rise to implant failure with prolonged periods of patient incapacitation and higher mortality risk.

Case Report: In this article, we report an unusual case of a 62-year-old male who developed a PJI 7 months after a THA.
