- CADAVERIC STUDY ON THE LEARNING CURVE OF THE TWO-APPROACH GANZ PERIACETABULAR OSTEOTOMY(2016) FERRO, Fernando Portilho; EJNISMAN, Leandro; MIYAHARA, Helder Souza; TRINDADE, Christiano Augusto de Castro; FAGA, Antonio; VICENTE, Jose Ricardo NegreirosObjective: The Bernese periacetabular osteotomy (PAO) is a widely used technique for the treatment of non-arthritic, dysplastic, painful hips. It is considered a highly complex procedure with a steep learning curve. In an attempt to minimize complications, a double anterior-posterior approach has been described. We report on our experience while performing this technique on cadaveric hips followed by meticulous dissection to verify possible complications. Methods: We operated on 15 fresh cadaveric hips using a combined posterior Kocher-Langenbeck and an anterior Smith-Petersen approach, without fluoroscopic control. The PAO cuts were performed and the acetabular fragment was mobilized. A meticulous dissection was carried out to verify the precision of the cuts. Results: Complications were observed in seven specimens (46%). They included a posterior column fracture, and posterior and anterior articular fractures. The incidence of complications decreased over time, from 60% in the first five procedures to 20% in the last five procedures. Conclusions: We concluded that PAO using a combined anterior-posterior approach is a reproducible technique that allows all cuts to be done under direct visualization. The steep learning curve described in the classic single incision approach was also observed when using two approaches.
- Arthroscopic bullet removal from the hip joint and concurrent treatment of associated full-thickness chondral defects: A case report(2019) FERRO, Fernando P.; BESSA, Felipe S.; EJNISMAN, Leandro; GURGEL, Henrique M. C.; CROCI, Alberto T.; VICENTE, Jose R. N.The diagnosis of a bullet inside the hip joint is a rare finding. The usual method to treat this condition has been open surgery, with its associated complications and morbidity. The arthroscopic approach has been increasingly utilized for the diagnosis and treatment of several hip conditions, and the number of indications for this technique has been steadily rising. We report the case of a 35-year-old man who suffered a gunshot wound and was operated on for abdominal perforation. He later presented with groin pain that worsened with weight-bearing on his right leg and then underwent arthroscopic removal of a bullet located inside his right hip joint. After a 2-year follow-up, the patient had an excellent clinical outcome, with no radiologic signs of arthritis. The removal of an intra-articular projectile is necessary to avoid complications such as synovitis, osteoarthritis, septic arthritis, and saturnism. The best access to the hip joint remains a topic of debate. Arthroscopy has the advantage of less soft-tissue damage and quicker recovery. The treatment of associated chondral lesions can be done with several techniques, including microfracture, autologous chondrocyte implantation, mosaicplasty, and fresh osteochondral allograft transplantation. There is no consensus as to the best course of treatment for associated chondral lesions in such cases. Hip arthroscopy can be a safe and effective technique for the removal of intra-articular bullets in the hip.
