This application is a Continuation of U.S. patent application Ser. No. 10/053,931 filed Jan. 22, 2002 (now U.S. Pat. No. 6,953,480), which is a continuation-in-part of application Ser. No. 09/558,044 filed on Apr. 26, 2000 (now U.S. Pat. No. 6,676,706), the disclosures of which are hereby explicitly incorporated by reference herein.
The invention, in another form thereof, comprises a method of performing a total hip arthroplasty. The method of this form of the current invention includes the steps of: placing the patient in supine position; palpating the femoral neck and making an anterior incision of about 3.75-5 centimeters (1.5-2 inches) in line with the femoral neck and the central axis of the acetabulum; performing a blunt dissection of the muscle exposed by the anterior incision to expose the capsule of the hip joint; incising the capsule of the hip joint; retracting a portion of the capsule to visually expose the femoral neck; utilizing an osteotomy guide to mark a cut path along which a cut will be made to remove the femoral head and a portion of the femoral neck; cutting along the cut path; incising the ligamentum teres femoris; in situ morselizing the cut away femoral head and neck as necessary for removal through the anterior incision; removing the morsels of the femoral neck and head through the anterior incision; reaming the acetabulum; seating the appropriate acetabular cup in the reamed acetabulum; inserting a curved awl having a substantially straight distal end into the anterior incision; aligning the distal end of the awl with the femoral axis; palpating the distal end of the awl and making a posterior incision having a length of about 2.5-3.75 centimeters (1-1.5 inches) at the location of the distal end of the awl; performing a blunt dissection to provide an access through the posterior incision to the femoral shaft; threading a retractor into the recess formed between the posterior incision and the femoral shaft; passing a guide wire through the retractor and into the cancellous bone of the femoral shaft; positioning the guide wire in the cannula of a femoral reamer; reaming the femoral shaft with the femoral reamer using the guide wire to locate the cancellous bone of the femur; observing the reaming activity through the anterior incision; removing the femoral reamer; utilizing the guide wire to guide a rasp to the femoral shaft; positioning the rasp in the femoral shaft while observing through the anterior incision; removing the guide wire; removing the retractor from the posterior incision; positioning a trial acetabular liner in the acetabular cup through the anterior incision; affixing a provisional neck to the rasp through the anterior incision; affixing a provisional head to the provisional neck through the anterior incision; performing a trial reduction with the trial acetabular liner, provisional neck and provisional head in place; dislocating the provisional head; removing the trial acetabular liner through the anterior incision; removing the provisional neck and head through the anterior incision; removing the rasp through the posterior incision; seating a final acetabular liner in the acetabular cup through the anterior incision; inserting a femoral implant through the posterior incision; inserting a final femoral head through the anterior incision; affixing the final femoral head to the femoral implant; reducing the hip; and closing the incisions.
The invention, in another form thereof, comprises a provisional femoral neck apparatus including a provisional femoral neck having a hollow, substantially cylindrical body. A spring biased locking piston is provided and housed within said hollow cylindrical body. The locking piston includes a tapered body portion. Application of a radial force to the tapered body portion moves the locking piston against the biasing force of the spring. The blades of a forceps may be utilized to apply the radial force to the tapered portion of the locking piston.
FIG. 21A is a partial elevational view along line 21A-21A of FIG. 21;
According to the method of total hip arthroplasty of the current invention, patient 40 is initially placed in a supine position on an operating table. Either a standard operating table or, alternatively, a radiolucent Jackson table is used. A radiolucent Jackson table is preferred if the surgical team intends to use intraoperative image intensification. In one exemplary embodiment, a Storz viewsite endoscopic system can be used. A Storz viewsite endoscopic system provides a sterile viewing screen for endoscopic images. The sterile viewing screen of a Storz viewsite endoscopic system can be positioned within the surgical field immediately adjacent to anterior incision 44. Other known endoscopic systems may further be utilized during the total hip arthroplasty of the present invention. Referring now to FIG. 2, with ipsilateral leg 48 in a neutral position, two prominent bony landmarks are palpated, the anterior superior iliac spine (ASIS) 59 and the greater trochanter 58 of femur 62. Ilium 64 and pubis 66 of hip 68 are shown to better illustrate the relevant area of the body. In one exemplary embodiment, the approximate anterior incision starting point 71 is identified two fingerbreadths inferior and two fingerbreadths anterior to the tubercle of the greater trochanter 58. The approximate finish point for the anterior incision is identified three fingerbreadths inferior and two fingerbreadths lateral to the anterior superior iliac spine (ASIS) 59. In another exemplary embodiment, the approximate anterior incision starting point 71 is identified 3-4 centimeters inferior and 2 centimeters lateral to ASIS 59. Having identified starting point 71 3-4 centimeters inferior and 2 centimeters lateral to ASIS 59, the path of anterior incision 44 is extended obliquely from starting point 71 toward the prominence of greater trochanter 58 along the axis of femoral neck 60. With the use of a spinal needle, the appropriate starting point 71 and the path of the anterior incision are identified by impaling the skin down to bone to confirm the central axis 70 of femoral neck 60.
Leg 48 is externally rotated to create tension on capsule 74. Capsule 74 is incised along the axis 70 (FIG. 2) of femoral neck 60 from the equator of femoral head 56 to the intertrochanteric ridge on the femur 62. The capsular incision takes the form of an �H-shaped� window formed by incisions 72. The H-shaped window is formed by adding supplementary perpendicular limbs around the equator of the femoral head 56 and the base of the femoral neck 60 to the initial incision along the axis 70 of femoral neck 60. As a form of retraction, heavy sutures are used to provisionally attach the capsular flaps 73 to the subcutaneous tissues. As illustrated in FIG. 3, retractors 76 are placed inside capsular flaps 73 and underneath the superior and inferior borders of femoral neck 60 to expose the entire length of femoral neck 60 from the inferior aspect of femoral head 56 to the intertrochanteric ridge. Retractors 76 can be, e.g., Cobra retractors. In one exemplary embodiment, each retractor houses a light source and can also serve to anchor an endoscope. Retractors 76 thereby provide continuous visualization and illumination of the wound. In one exemplary embodiment, JAKOSCOPE retractors having integral fiberoptic light sources are utilized in accordance with present inventions.
Retractors 76 are repositioned around the anterior and posterior rims of the acetabulum. A custom curved cutting tool. (i.e., the �ligamentum teres cutter�) is passed behind femoral head 56 to sharply incise the ligamentum teres, thus mobilizing cut portion 88 as illustrated in FIG. 6. Cut portion 88 includes femoral head 56 as well as a portion of femoral neck 60 (FIG. 4). Cut portion 88 is thereafter removed through anterior incision 44 with a custom femoral head bone grasper 94 (FIG. 7). If there is difficulty removing cut portion 88 in one piece, it may be in situ morselized using cutting tool 87 (FIG. 6), e.g., a power burr. Morsels 92 may then be removed through anterior incision 44. Morselizing of cut portion 88 is accomplished making cuts which substantially mirror the cuts in hip capsule 74. In one exemplary embodiment, a corkscrew and hip skid removes the entire femoral neck, as in hip fracture. Irrigation and suction devices can be used to cool the bone and facilitate the removal of bony debris in hip capsule 74. In one exemplary embodiment, a fiberoptic endoscope is placed into the hip joint to confirm the complete removal of bony debris.
After a trial fitting, a press-fit acetabular cup of the appropriate size is firmly seated with a standard cup inserter 100 as illustrated in FIG. 9 and impacted into the acetabular recess as is known in the art. Acceptable press fit acetabular cups include the ZIMMER HGP II or TRILOGY cups. Proper positioning of the acetabular cup is achieved with a custom anteflexion and pelvic alignment guide. Patient 40 is placed in supine position on operating table 102. Aligning rod 104 is aligned with the mid lateral axis of torso 52 while main shaft 105 is maintained approximately 30� from operating table 102 for proper seating of the acetabular cup. To augment fixation of the cup, a flexible drill can be used to guide the placement of one or more acetabular screws. In some cases, acetabular screws will not be necessary. The insertion of the acetabular liner is deferred until the proximal femur has been prepared for the insertion of a trial stem. As illustrated by the anterior elevational view of FIG. 10, patient 40 remains in the supine position on operating table 102 (FIG. 9) while cup inserter 100 is utilized to seat the acetabular cup.
For preparation of the femur, the patient is repositioned with a pad placed under the ipsilateral hip. The hip is slightly flexed, adducted approximately 30�, and maximally externally rotated. Retractors 76 are repositioned around the medial and lateral aspects of femur 62. Alternatively, a self-retaining retractor with a light source attachment and an endoscope holder can be positioned in anterior incision 44 to provide constant visualization and illumination of femur 62.
FIG. 16 illustrates preparation of femoral canal 148 to receive rasp 204 (FIG. 19). Guide tube 124 is removed from posterior retractor 122 and end cutter 150 (FIG. 17A) is inserted through reamer tunnel 126. FIG. 18 illustrates end cutter 150 positioned within reamer tunnel 126. End cutter 150 includes elongate aperture 160 through which guide wire 146 passes and guides end cutter 150. End cutter 150 is actuated by any of the many actuating devices known in the art. After end cutting is complete, end cutter 150 is removed through reamer tunnel 126 and reamer 151 (FIG. 17B) is inserted therethrough. Reamer 151 includes reamer guide aperture 161 through which guide wire 146 passes and guides reamer 151 as it reams femoral canal 148. Reamers of progressive increase in their outer diameter are sequentially placed over guide wire 146 and femoral canal 148 is reamed until cortical �chatter� is felt. As is known in the art, the optimal diameter of femoral canal 148 is provisionally determined by preoperative templating. Some surgeons may choose to avoid reaming of the femoral shaft and instead utilize a broach as is known in the art. A broach may be inserted in accordance with the current invention as described hereinbelow with respect to rasp insertion.
After the final rasp is seated in femoral canal 148, a trial acetabular liner is placed through anterior incision 44 and into the seated acetabular cup with the use of a liner inserter as is known in the art. Provisional neck 222 is inserted through anterior incision 44 and locked to the top end of the seated rasp, as illustrated in FIG. 22. A trial femoral head is placed on the Morse taper of provisional neck 222 through anterior incision 44. The hip joint is reduced for an assessment of stability of the hip joint and limb length. Where necessary, a second assessment is made. Once the trial reduction is satisfactorily completed, the hip is dislocated and the provisional head and provisional neck 222 are removed. Rasp handle 212 is reinserted through posterior incision 46 over the free end of flexible cable 192. Rasp handle 212 is advanced until it can be locked with the seated rasp so that impact surface 164 can be impacted and the entire tool (i.e., rasp 204 and rasp handle 212) can be removed. The trial acetabular liner is removed through anterior incision 44. In an alternative embodiment, a trial reduction can be performed utilizing the final femoral implant and a trial femoral head.
Via anterior incision 44, the final acetabular liner 252 (FIG. 30) is seated into acetabular cup 250 (FIG. 30) with a liner inserter that permits its impaction in place, as is known in the art. Femoral implant 238 (FIG. 30) is anchored to femoral stem insertion tool 240 (FIG. 29) and placed through posterior incision 46. Femoral implant 238 can be, e.g., a VERSYS fiber metal taper, or a VERSYS fiber metal midcoat available from Zimmer, Inc. As illustrated in FIG. 25, femoral implant 238 is placed in protective, disposable bag 242 prior to its introduction into posterior incision 46. Protective, disposable bag 242 keeps femoral implant 238 clean as it is inserted through posterior incision 46. Note that FIG. 25 illustrates femoral implant 238 oriented as it will be when placed in femur 62. To insert femoral implant 238 through posterior incision 46, femoral implant 238 must be rotated 180� from this position to prevent impingement on the body. Femoral implant 238 is then rotated 180� after being completely inserted through posterior incision 46.
FIG. 26 illustrates femoral stem 238 and bag 242 inserted through posterior incision 46. When the tip of femoral stem 238 approaches the osteotomized femoral neck, the distal end of bag 242 is incised as illustrated in FIG. 27. Scalpel 246 is inserted into anterior incision 44 to incise bag 242. As femoral stem 238 is driven into femoral canal 148, bag 242 is progressively removed through posterior incision 46 as illustrated in FIG. 28. After femoral stem 238 is fully seated, femoral stem insertion tool 240 (FIG. 29) is removed through posterior incision 46. Through anterior incision 44, the final femoral head is positioned on the femoral neck Morse taper using a standard holding device and secured with a standard impaction tool and mallet. The hip is then reduced and assessed for stability.
Osteotomy guide 78, illustrated in use in FIG. 4, includes handle 80, alignment portion 82, and cut guide 84. In one exemplary embodiment, cut guide 84 and alignment portion 82 form a 60� angle. In one exemplary embodiment, alignment portion 82 includes a tapered distal end as illustrated in FIGS. 5A and 5B. Osteotomy guide 78 is inserted through anterior incision 44 and is positioned with alignment portion 82 being placed on femur 62 so that alignment portion 82 generally aligns with the longitudinal axis of femur 62. Handle 80 protrudes through anterior incision 44 and may be utilized to position osteotomy guide 78. After osteotomy guide 78 is properly positioned, cut guide 84 is utilized to mark cut line 85 on femoral neck 60 as illustrated in FIG. 4. Osteotomy guide 78 can be formed to function on either side of the body. FIG. 4 illustrates an osteotomy guide designed to function on the right femur, while FIG. 5B illustrates an osteotomy guide operable to function on the left femur.
