This is the first report of a successful first metatarsophalangeal joint medial bipartite sesamoidectomy using great toe arthroscopy. The surgical trauma associated with open operative sesamoidectomy can be minimized using minimally invasive techniques under arthroscopic control. The authors describe the surgical principles and discuss the advantages compared with traditional surgery.
An 18-year-old woman suffering from lateral patellar pain and subluxation underwent knee arthroscopy. The arthroscope revealed a bifurcate appearance of the popliteus tendon. This is the first report of this appearance at arthroscopy. The bifurcate popliteus tendon is a normal variant finding with no clinical significance.
Arthroscopic assessment and treatment of tibial plateau fractures has gained popularity in recent years. This article describes some maneuvers to facilitate the management of these fractures with the arthroscope. We use a 14-mm rounded curved periosteal elevator to manipulate fragments within the joint instead of using a probe. To facilitate visualization of fractures, we describe the use of loop sutures around the meniscus to retract the meniscus when there is a tear in the meniscus. We suggest the use of the arthroscope for directly viewing the interosseous space to be sure that any internal fixation devices remain outside the articular space. The use of these tactics will allow a faster, more accurate reduction with less radiation exposure in patients with displaced tibial plateau fractures.
We report a case of spontaneous avascular necrosis of the knee successfully treated with core decompression and arthroscopic bone grafting with a bone plug of autogenous graft obtained from the iliac crest. A 2-year follow-up shows excellent clinical and magnetic resonance imaging results.
Disruption of the extensor mechanism of the knee joint at the insertion site of the patellar tendon into bone is a somewhat common injury. Avulsion of the patellar ligament associated with fractures of the proximal tibial epiphysis is an extremely rare injury. Only three cases have been published in association with avulsion fracture of the tibial tubercle. We are reporting a case that has previously not been reported to our knowledge: an avulsion of the ligament in a closed fracture of the proximal tibial epiphysis with integrity of the tibial tubercle. We propose a three-type classification of an avulsion patellar ligament injury.
A case of fracture of the styloid process of the temporal bone (Eagle's syndrome) is reported. The differential diagnosis is discussed.
A technique for arthroscopic treatment of anterior intercondylar eminence is described. This technique avoids the use of screws, making it unnecessary for a second operation to remove them.
Magnetic resonance imaging (MRI) was used to help in the diagnosis of a teratoma in the gluteus maximus region. As far as we know no case of this kind of tumour has been investigated with MRI examination.
Stress fractures of the ulna are extremely rare. The purpose of this article is to report one more case of this occurrence in an eleven-year-old girl, who was using adjustable metal crutches, and to discuss the possible cause.
