Association of the Number of Teeth With Physical Function and Length of Hospital Stay After Hip Fracture Surgery: A Prospective Observational Study at a Tertiary Hospital in Japan.

Objectives: Although lower-extremity muscle strength is associated with physical function, there are challenges in assessing the muscle strength of patients after hip surgery due to pain or limited cognitive function. The number of teeth is a characteristic that can be easily examined. Although the relationship between the number of teeth and physical function has been reported in recent years, there are no reports examining the relationship with prognosis in patients with hip fractures.

Periprosthetic Fracture Resembling Atypical Femoral Fracture After Fixation With Retrograde Intramedullary Nail in Elderly Women: A Report of Two Cases.

Background/aim: The number of individuals diagnosed with and requiring medical treatment for osteoporosis continues to increase due to global population aging and the high awareness of osteoporosis. Bone-modifying agents (BMAs) including bisphosphonate and denosumab are widely used for osteoporosis, and atypical femoral fracture (AFF) is also gaining attention as a severe potential side effect of long-term BMA treatment. The definition of AFF excludes periprosthetic femoral fracture; here, we describe two cases of a periprosthetic femoral fracture that resembled AFF.

'Acute Masquelet technique' for reconstructing bone defects of an open lower limb fracture.

Introduction: The reconstruction of bone defects of open lower leg fractures is challenging, and there is no established treatment strategy to date, especially in the acute phase. We report herein an 'acute Masquelet technique' for reconstructing bone defects of open lower limb fractures as the primary treatment in the acute phase.

Patients And Methods: We retrospectively analyzed the outcomes of seven lower limbs of the seven Japanese patients (five males, two females, aged 24-76 years [mean 53 years]) who underwent the acute Masquelet technique for open fractures with bone defects.

Surgical treatment options for septic non-union of the tibia: two staged operation, Flow-through anastomosis of FVFG, and continuous local intraarterial infusion of heparin.

Background: The treatment of septic non-union of the tibia is a challenging area.　The objective of this clinical study was to improve the treatment outcomes in patients with a highly active infection by the three strategies consisting of a two-staged operation, a flow-through technique for vascular anastomosis of a free vascularized fibular graft (FVFG), and continuous local intra-arterial infusion of heparin.

Patients & Method: Five patients with septic non-union of the tibia who were treated with an FVFG (mean age: 52.

SURGICAL TREATMENT FOR INFECTED LONG BONE DEFECTS AFTER LIMB-THREATENING TRAUMA: APPLICATION OF LOCKED PLATE AND AUTOGENOUS CANCELLOUS BONE GRAFT.

Background: Treatment strategies for bone defects include free bone grafting, distraction osteogenesis, and vascularized bone grafting. Because bone defect morphology is often irregular, selecting treatment strategies may be difficult. With the Masquelet technique, a fracture site is bridged and fixed with a locking plate after treating deep infection with antibiotic-containing cement, and a free cancellous bone-graft is concomitantly placed into the defects.

Contralateral neuropathic pain and neuropathology in dorsal root ganglion and spinal cord following hemilateral nerve injury in rats.

Study Design: The contralateral pain-related behavioral and immunohistochemical changes after hemilateral spinal nerve injury in rats were investigated.

Objectives: We evaluated the longitudinal changes in contralateral mechanical allodynia, expression of tumor necrosis factor (TNF)-alpha and glial fibrillary acidic protein (GFAP)-positive satellite cells in the contralateral dorsal root ganglion (DRG), and expression of astrocytes and microglia in the contralateral spinal dorsal horn after hemilateral spinal nerve injury in rats.

Summary Of Background Data: In previous studies, hemilateral nerve injury has sometimes induced contralateral neuropathic pain.
