Risk of Anticoagulation in Gluteal Compartment Syndrome After Surgical Intervention.

Gluteal compartment syndrome (GCS) is a rare form of acute compartment syndrome. There are some causes, such as prolonged periods of immobilization and traumatic or iatrogenic events. We report two cases of gluteal compartment syndrome after orthopedic surgical intervention for fracture stabilization. The patients were both hypocoagulated due to the presence of two mechanical heart valves. Despite early treatment, both patients remained with neurological deficits. Orthopedic and trauma surgeons must be aware of the possibility of gluteal compartment syndrome in perioperative patients. Recognizing and managing risk factors such as hypocoagulation is crucial for its prevention.

Arthroscopically Assisted Reduction and Internal Fixation of Talar Neck Fracture: A Case Report.

INTRODUCTION: Arthroscopic-assisted reduction and internal fixation (ARIF) is a recent concept and is increasingly used for articular fractures, due to the minimally invasive nature and high accuracy. However, there are few reports in literature about this procedure in talar fractures. CASE REPORT: The authors describe a clinical case of a 22-year-old woman with a closed right articular talar neck fracture, Hawkins type II, treated with arthroscopically ARIF. CONCLUSION: This is a minimally invasive technique that can allow close accurate reduction and stable fixation of selected articular talar fractures. It avoids some complications of multiple and large incisions of the conventional open surgery, with good functional outcomes and patient satisfaction.

Giant Cell Tumor with Fracture of the Proximal Radius - Reconstructive Surgery with Radius Allograft.

INTRODUCTION: Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that accounts for 4-10% of all primary bone tumors. It affects mostly young adults and occurs more frequently at the bones around the knee followed by the distal radius and the sacrum. Surgical treatment with curettage is the optimal treatment for local tumor control, but it can be associated to suboptimal functional outcome when located in periarticular regions. CASE REPORT: We describe a 47-year-old Caucasian female who presented with pain in the proximal third of the left forearm without history of traumatism. The study performed revealed a pathological fracture of the proximal radius associated with lytic lesion. The patient underwent excision and curettage of the lesion with preservation of the periosteum, filling with the left proximal radius (corpse) allograft and osteosynthesis with plate and screws. The anatomopathological examination revealed characteristics compatible with GCT. CONCLUSION: This case presents some unique features: The extremely rare location of the GCT at the proximal end of the radius, its initial presentation as a pathological fracture, and the type of treatment performed (reconstruction with the left proximal radius allograft-corpse), with good results.

APSI scaphoid hemiarthroplasty - long-term results / Hemiartroplastia do escafoide com APSI - resultados funcionais em longo prazo

ABSTRACT Objective: This study is aimed at evaluating the long-term results of proximal scaphoid hemiarthroplasty for post-traumatic avascular necrosis at this institution. Methods: Twelve patients who underwent this procedure were identified, and the mean follow-up time was 6.5 years (range: 5-8 years). All patients were male, with a mean age of 39 years (range: 28-55 years). In eight patients, the non-dominant limb was affected. The procedure was carried out through a dorsal approach and all patients underwent the same rehabilitation protocol. Cases were evaluated regarding complications, pain, range of motion, functional status (Mayo Wrist Score), and disability (QuickDASH Score). Results: No immediate post-operative complications, such as infection or dislocation of the implant, were observed. All patients presented with peri-implant osteolysis at follow-up, on a radiograph study. None of the patients was forced to abandon their previous professional activity, although about 50% required some type of adaptation at their workplace. The mean functional capacity was, according to the Mayo Wrist Score, of 67.5 points (range: 50-80), corresponding to a satisfactory degree of function. The QuickDASH disability score presented a mean of 25 (range: 3-47.7). Conclusion: The results of this series are in line with previously published studies about this technique. Hemiarthroplasty with a pyrocarbon implant is a safe technique for the treatment of post-fracture avascular necrosis of the scaphoid proximal pole. This technique allowed for satisfactory functional results at a mean follow-up of 6.5 years.

RESUMO Objetivo: Avaliar os resultados em longo prazo da hemiartroplastia do escafoide proximal no tratamento da osteonecrose avascular pós-traumática na instituição. Métodos: Foram identificados 12 pacientes submetidos a esse procedimento. O tempo médio de seguimento foi de 6,5 anos (entre cinco e oito). Todos os pacientes eram do sexo masculino, com média de 39 anos (entre 28 e 55). Em oito pacientes o membro afetado foi o não dominante. O procedimento foi feito por meio de uma abordagem dorsal e todos os pacientes foram submetidos ao mesmo protocolo de reabilitação. Todos os casos foram avaliados quanto à ocorrência de complicações, dor, amplitude de movimento, capacidade funcional (Mayo Wrist Score) e incapacidade (QuickDASH Score). Resultados: Não foram observadas complicações no período pós-operatório imediato, como infeção ou luxação do implante. No fim do período de seguimento, todos os casos apresentavam osteólise peri-implante no estudo radiográfico. Nenhum dos pacientes abandonou a sua atividade profissional prévia à cirurgia, embora em cerca de 50% dos casos tenha sido necessário algum tipo de adaptação no local de trabalho. A capacidade funcional média foi, de acordo com o Mayo Wrist Score, de 67,5 pontos (entre 50 e 80), correspondeu a um nível de função satisfatório. O escore de incapacidade QuickDASH apresentou uma pontuação média de 25 (entre 3 e 47,7). Conclusão: Os resultados desta série encontram-se em linha com os estudos publicados sobre essa técnica. A hemiartroplastia do escafoide com implante de pirocarbono é uma técnica segura para o tratamento da necrose avascular do polo proximal do escafoide após fratura. Essa técnica permitiu obter um resultado funcional satisfatório após uma média de 6,5 anos de seguimento.

Extrapulmonary tuberculosis: importance of differential diagnosis.

Patients with tuberculosis (TB) typically present with pulmonary TB, but extrapulmonary TB is also an important clinical problem. In particular, osteoarticular TB has a great morbidity and its diagnosis gold-standard includes culture and histopathology of the infected area. The present case study describes a 53-year-old female Portuguese farmer who had initial clinical and imaging features suggestive of tuberculous osteomyelitis. However, she denied any TB contacts and the tuberculin skin-test and interferon-γ release assay result were negative. Brucella melitensis was isolated from a tissue biopsy cultural examination, and treatment for brucellosis was started, yielding a favourable outcome. In similar circumstances, a precise diagnosis, that considers the epidemiological context, is crucially important for adequate treatment and reduction of morbidity.
