Extension of the fingers is a complex function carried out by simultaneous action of extrinsic and intrinsic muscles, as well as retinacular structures in the dorsum of the wrist, hand, and fingers that support and coordinate the action of the muscles. The extensor mechanism of the fingers is divided into topographic zones, which extend from the forearm to(More)
We studied the effect of the procurement team on the risk of contamination in 270 large bone allografts retrieved from 53 non-living donors under strictly aseptic conditions. The overall contamination rate was 8.1%. When the procurement team was constituted by three or less members the contamination rate was 5.6%, while if there were four or more members(More)
The navicular bone, located in the midfoot, articulates with the head of the talus, cuboid, and the three cuneiform bones that are involved in the acetabulum pedis. It gives attachment to the spring ligament (superomedial and inferior calcaneonavicular ligament)that can be injured in a failure of the posterior tibialis tendon and cause an adult acquired(More)
PURPOSE The purpose of this study was to evaluate the outcome after 5 years of allografts as bone growth material and success of implants inserted in fresh-frozen allograft bone. MATERIALS AND METHODS A total of 20 patients were operated and 41 onlay block freeze-dried allografts (calvarial and iliac crest) were inserted for bone augmentation. A total of(More)
The scaphotrapeziotrapezoidal (STT) joint is a complex joint in which the arthroscope and instruments can be used through the radial midcarpal and STT-ulnar portals. This report describes a new arthroscopic portal at the STT joint to complete and improve the evaluation and treatment of this joint by arthroscopy: The STT-radial (STT-R) portal is situated(More)
Freiberg disease is a disorder that has a predilection for the second metatarsal head. Keller excision of the base of the proximal phalanx is a procedure described for the treatment of late-stage Freiberg disease. We describe a case of a 60-year-old man, with a stage IV lesion according to Smillie's classification, treated by debridement, removal of the(More)
The primary aim of this work was to evaluate the neurovascular network of the pes anserinus (PA) at its tibial insertion because the PA is often used for anterior cruciate ligament (ACL) reconstruction. Four fresh cadaver knees were injected with India ink gelatin solution and the arteries that supply blood to the PA were identified; microscopic studies of(More)
INTRODUCTION Swab cultures are the most usual method to detect graft contamination; nevertheless it has been confirmed his limited sensibility. We have studied the relationship between blood cultures, swab surface cultures and cultures of entirely samples of cancellous bone. MATERIAL AND METHODS We have evaluated 5 donors with positive blood culture, from(More)
INTRODUCTION The allogeneic meniscal transplantation (AMT) has received much attention lately for the treatment of young, active patients with painful knees previously subjected to meniscectomy. OBJECTIVE Show the current concepts on AMT as well as the methods for meniscal harvesting, processing and preservation that the Tissue Bank must implement. (More)
