Introduction: During revision surgery for the management of patients presenting with long-bone upper extremity nonunion, it is crucial to rule out fracture-related infection (FRI). This is especially true if there are clinical signs suggestive of FRI, or if there is a history of prior FRI, open wound fracture, or surgery. This study aimed to determine the efficacy of frozen section analysis (FSA) in providing real-time diagnosis of FRI in patients with upper-limb long-bone nonunion undergoing revision surgery.

Introduction: aneurysms are focal and permanent dilations of an artery; in pseudoaneurysms, the normal layers of the blood vessel are replaced by fibrous tissue. Due to their low incidence, as well as the diagnostic and therapeutic challenge they represent; our objective is to present the clinical case of a pseudoaneurysm of a digital artery of the hand and to carry out a systematic review of this pathology.

Material And Methods: literature search in Medline, using the terms "digital artery" and "aneurysm.

Case: In the setting of a total hip arthroplasty performed in a patient with a proximal femoral deformity, atraumatic periprosthetic femoral stress fracture may arise as a complication. We report a rare case of a late periprosthetic femoral stress fracture around a cemented stem in a patient with a history of fibrous dysplasia of the proximal femur. After a 10-year uneventful period, the patient complained about a subtle, subacute pain in his left thigh induced by exercise but not with daily axial load.

Introduction: Diaphyseal forearm fractures in skeletally immature patients are common injuries that account for 30% of upper extremity fractures in this age group. There are cases with unstable injuries or unacceptable reductions, in which surgical resolution by reduction and stabilisation with percutaneous elastic endomedullary nailing is indicated. One of the advantages of this system is that it avoids an approach to the fracture site, allowing closed reduction in the vast majority of fractures.

Background: To evaluate the sustainability of the early clinical and radiological outcomes of terrible triad injuries at long-term follow-up.

Methods: Twelve consecutive patients who underwent fixation of terrible triad injuries with minimum of seven years of follow-up. Functional and radiological outcomes at one year and final follow-up were compared.

Article Synopsis
  • Ewing sarcoma is a rare and aggressive bone tumor that primarily affects children and young adults, with limited data on its prevalence and treatment in Argentina due to the absence of registries.
  • A study analyzed 88 patients diagnosed with Ewing sarcoma and treated with chemotherapy and limb-salvaging surgery, revealing an overall 5-year survival rate of 69% and identifying poor response to chemotherapy, older age, central tumor location, and local recurrence as negative prognostic factors.
  • The research concluded that response to chemotherapy is the most significant factor influencing both overall survival and local recurrence, highlighting the effectiveness of combined chemotherapy and surgery for treatment.

Introduction: Fasciitis of the limb and toxic-shock syndrome due to Streptococcus Pyogenes infection is considered a surgical emergency. This condition may occur in previously healthy patients. It is a life-threatening condition with high morbidity rates when treatment is delayed due to poor diagnosis and non-surgical intervention.
