Years ago I slipped in the corridor of the operating room on a floor smeared with soap. During the fall I incurred a dislocation of the right metacarpophalangeal joint of the thumb. While I was getting up I reduced the thumb myself and continued my OR program.A forceful closure of the fist was very painful for about three months.
Working normally with the Woodpecker® would not have been possible if the manufacturing company had not produced very quickly a custom-made design with a 90° pivotable rasp holder.I was working with the broach rotated 90°, it occurred to me that the grip displays the direction of the bent lower leg, laid across the opposite leg in the Patrick’s Test. As a result, the femur antetorsion can be controlled better than with the usual position of the hand grip.The hand has long since healed. The 90° rotation of the broach has remained. The modification became the standard.
Manipulation of the intramedullary canal may lead to bone marrow release, an increase of the intramedullary pressure and to fat embolism syndrome in joint arthoplasty. Identification of risk patients and a modification of the surgical technique are important.
The use of a pneumatic rasping machine is one essential instrument in this modified surgical technique. But further more, it provides a gentle and improved modeling of the proximal femur and reduces the risk of fissuring the bone. As soon as you are use to The Woodpecker, you cannot imagine returning to the hammer.
I have been using the Woodpecker for preparation of the femoral canal in Total Hip Replacement for ten years or more. I first began using the system with the Zweymueller (Alloclassic) stem. This is a proportionally sized, collarless, tapered stem with rectangular cross section. This stem configuration makes it ideal for the Woodpecker Impact reamer/broach system. Over the years, I have used the Woodpecker for similar stem designs from various manufacturers including Zimmer, Wright Medical’s Profemur Z, and currently, Smith Nephew’s Platform stem.
When performing a hip replacement, is important to accurately broach the femoral canal to get an ideal prosthetic fit. I feel that I can do this more accurately and safely with the Woodpecker than I can do by hand. By using the Woodpecker to control lateral reaming, I can get into the trochanter far enough to prevent the stem from going into varus. The pistol grip of the Woodpecker allows me to simply set anteversion of th…
I have been using the Woodpecker device for femoral broaching for the past several years. I have found this to be highly efficient and effective. Old broaching techniques called for hammering which causes peaks of hoop stresses in the proximal femur and can often lead to splits when the broach becomes tight. It is also very hard on the surgeon’s wrist and carpal bones.
The Woodpecker has allowed us to broach the femurs, and in the four years I can recall one split in some very osteoporotic bone. Most of the time, the broaching is extremely efficient, and I have tested the efficacy by broaching to the maximum with the Woodpecker and then attempting to broach further with the old method using a hammer. This is never possible. The Woodpecker broaches maximally, efficiently, and painlessly. I have used this device as a prosthesis introducer and have found this to be equally as efficient.
I have introduced the prostheses to the “end-point” with the Woodpecker. I the…
Use of The Woodpecker® allows a gentle yet powerful and precise preparation for the femoral canal in a total hip arthroplasty. One aspect of the femoral preparation is the speed of preparation. The time it takes to prepare a perfect envelope in the femur is between 90 and 120 seconds when the final implant is now ready to be gently tapped in. Due to the fact that there is no variation of percussion of the broach, it is very unlikely to fracture a femur. It will allow the broach to stop on its own to place the distal stem directly opposed to the endosteum of the femoral canal .There is very rarely any evidence of stem subsidence. The use of compaction of marrow allows the stem cells of the bone marrow to be preserved allowing a rapid biologic integration to the titanium stem.
The rapidity of the preparation reduces the amount of bleeding due to compression of the marrow which slows bleeding from its vessels and the ability of placement of the final implant early in th…Orthopedic surgeon Wayne M Goldstein - Professor of Clinical OrthopedicsMorton grove, IL
I have done over (1000) Woodpecker® broached THAs over ten years using Square taper Z stems on patients age range 13-103 and have had 0 femur fractures and no stem subsidence or loosening.
