The authors review 21 cases of a so-called "reposition-flap" technique for finger tip injuries consisting of simple reposition when no vessels can be found for replantation. This technique is combined with palmar soft tissue excision and advancement of a local flap to cover the bone providing blood supply and good sensitivity. The mean age in the 19(More)
Carpal tunnel release is frequently followed by weak grasp but recently, endoscopy has been claimed to avoid this pitfall. 277 patients representing 303 CT were enrolled in a prospective randomized study to assess changes in grasp after classical open CTR (Group I - 77 cases), ligamentoplasty (Group II - 133 cases) and an Agee endoscopic CTR (Group III - 99(More)
Fingertip injuries constitute a large portion of the traumatic injuries sustained to the hand and are frequently associated with significant disability for the patient. While many methods are available for the treatment of such injuries, quite often only certain procedures are appropriate for a particular digit in any given patient. The use of flaps in such(More)
Any transplanted muscle flap undergoes atrophy to an extent depending mainly on its innervation. Other factors such as the tension at rest and the duration of ischemia play a secondary role. An experimental study was carried out in rats to quantitatively assess the extent of atrophy according to the mode of transplant reinnervation. The gracilis muscle was(More)
The vascularization of the gracilis muscle of the rat is oriented mainly along the longitudinal axis of the muscle and arises from a muscular artery originating in the femoral artery. Transillumination study of the muscle after vascular injection with Microfil demonstrated this anatomic disposition. The gracilis muscle was used either as a pedicled transfer(More)
The authors describe a peninsular diamond-shaped flap raised from the dorsolateral surface of the index finger to cover a defect of the first web space. The donor site is covered by an "LLL" Dufourmentel flap tailored on the dorsum of the hand avoiding a skin graft on the exposed surface of the hand.
A prospective study of 280 endoscopic operations of the carpal canal using the AGEE technique were reported. The first 80 cases were studied separately from the 200 subsequent cases. In the first series, the only complication was the need for an incision in 6 cases because of technical problems or anatomic variants (13%). An increase in the degree of(More)
