Description
~one Nail For The Medical Care Of S~oke Bone Fractures The present invention refer~ to a bone nail for the medical care of spoke bone fractures according to the preamble of claim 1.
A variety of nails to be anchored in the mednll~ry ca~ity is known in the medical care of hollow bone fractures. Particu-larly useful are so-called locking nails to statically fix fractional fragments by means of cross bolts. Locking nails of this type are primarily used for the femur and the tibia.
German petty patent DE-GM 8S 34 358 discloses a bone nail for upper arm fractures which nail is slotted at its distal end to be P~p~nded by a spreading body cooperating with an int~rn~l thread of the nail shaft. The known upper arm nail is thus proximally inserted and distally anchored by the spre~;nq body. An anchoring of this type by forming one end of a bone nail as a sprP~ing dowel is known from European patent EP O 023 228.
A bone nail for the medical care of fractures of the human radius or spoke bone has not yet become known. The object of the invention is to pro~ide an intra~ ry bone nail which is suited for the medical care of bone spoke fractures.
The object is solved by the features of claim 1.
According to the invention the bone nail comprises a hollow nail shaft curved in a plane which shaft is slotted at its proximal end to be spread apart by a spre~in~ body. The bone nail is distally and posteriorly inserted and will be thus proximally locked like a str~l;ng dowel. A further locking is provided by a bone screw which extends ~hrn-~qh a cross bore in the distal end of the ~haft. The cross bore approximately extends normally to the curved plane of the nail. The curvature of the nail corresponds to the anatomic curvature of the spoke bone, however, the nail has to be inserted such, that it i9 turned at about ~0~ about its longit~ n~l axis while being driven in.
According to a further embodiment of the invention the cross bore is defined by an elongate opening. Thiq makes possible a dynamic process, i.e. the bone fragments may drift relatively with respect to each other in a longitu~;n~l direction, but are locked in the rotational direction. When the distal end of the nail shaft is provided with an intPrnAl thread receiving a screw bolt, a pressure may be exerted on the nail screw. Accordingly the nail o~ the present invention may be used as a compression device.
According to a still further embodiment of the invention the intern~ 1 threaded portion of the proximal end preferably extends towards both sides of the end of the slotted portion.
According to a further feature of the invention the pro~
end portion of the shaft is formed streight to suit anatomic conditions. In a further embo~ t, the invention provides for at least a reoess in the distal end of the shaft. The recess serves to apply a tool to perform the rotation above referred to, in driving-in the nail. To detect the cross bore after driving in the nail, a positioning unit is used which alike may cooperate with the distal end. The recess serves to fix the rotational position of the positioning device with respect to the nail shaft.
In a further . ~oA; -nt of the invention, opposite flats in the distal end portion of the shaft are providéd which flats are located approximately parallel to the cur~ed plane. When the nail is in its end position, the flats lie approximately parallel to the back of the hand so that the distal end of the nail is as little bulXy as possible.
Still further, the distal end portion of the shaft is slightly PYp~nded liXe a trumpet, preferably ext~n~i~g from the cross bore up to the distal end. Due to anatomic con-ditions the nail shaft may have a limited diameter. It is thus difficult to apply a suitable tool to the distal end.
By flaring the distal end, the application of a driving and manipulating tool and of the positioning device is facilita-ted. The transfer of axial blows and torque to the nail is i ~oved by flaring the nail.
According to a further feature of the invention, the length of the nail shaft is selected such that its pro~ end portion is located in the area of the tuberositas radii. In this area, the spoke bone is relatively pressure stable and has an approximately oval cross section so that fracturing the bone by str~ling the nail is minimized. Of course, a variety of nail lengths may be provided, preferably in steps of 10 mm, for example.
According to a further ho~; t of the invention, the spreading body comprises a cap, preferably made of metal, which cap is rotatably but ~x;ally fixed on the str~ling body formed as a screw bolt and comprising a conical str~l;nq face. By this, a friction occurs between the stra~dl;ng body and the nail shaft in axially shifting but not in rotating. This makes it possible to gently and effectively straddling the proximal nail end.
An embodiment of the invention is described in detail in referring to the drawings which show:
Fig. 1 a side view of a bone nail acc~rding to the invention, Fig. 2 a section through the distal end of the bone nail of Fig. 1 along the line 2-2 in Fig. 4, Fig. 3 a section through the nail of Fig. 1 along the line 3-3, Fig. 4 an end view of the bone nail of Fig. 1 in the direction of arrow 4, Fig. 5 a section through a nail of Fig. 1 along the line 5-5, Fig. 6 a view of a straddling body for the nail of Fig. 1, Fig. 7 a section through the screw bolt of the straddling body of Fig. 6 and Fig. 8 a section in an enlarged scale of a blank forming a cap for the stra~ling body of Fig. 6.
A hollow nail shaft 10 made of a body-compatible material of suitable strength is curved in a plane, wherein the proximal end portion 12 is formed straight. The proximal end portion 12 further includes a pair of diametral slots 14 separating the distal end portion in a pair of straddling tongues. The slots distally end in circular enla~g~ -rts 16 to stress-relieve the material when being straddled. The proximal end portion 12 is provided with an internal threaded portion 18 exten~ing at both sides of the distal ends of the slots 14.
In the distal end portion 20 the shaft 10 includes a cross bore 22 which is formed as an elongated opening exten~1 ng approximately vertical to the curvature plane of the shaft 10. Distal with respect to the bore 22, the end portion 20 i9 trumpet-like enlarged, but merely in the curvature plane as is clearly seen from Figs. 2 and 4. The distal end portion of the nail is oval, and a pair of opposite flats 24 and 26 is provided having a distance which approximately corresponds to the diameter of the nail shaft 20 in the remaining portion, while the remaining poartion of the nail is circular. A pair of diametral rece~ses 28, 30 is provided at the end. The distal end portion further includes an inter~l thread 32.
The nail shaft 10 is posteriorly inserted in the area of the back of the hand, wherein a spreading body 36 is received in the proximal end 12. The spreading member is described in referring to Figs. 6 to 8.
A bolt 38 has a shaft 40 including a head 42 and a threaded portion 44 at the opposite end. In the central portion the shaft 40 is grooved at 46. As seen from Fig. 7, the shaft 40 is provided with a through bore 48. At its distal end the shaft 40 i~ provided with an internal hexagon 48 or some-thing similar for applying a tool. A str~l;ng cap 50 sits over the shaft 40 and the head 42, which blank 50' is shown in Fig. 8. The blank is made of metal and its end includes a conical str~l; ng face 52 joining a cylindrical face 54.
The hollow blank 50' further includes an internal shoulder 56. The blank 50' is pushed over the bolt 38 from the threaded portion 44 until the shoulder 56 contacts the underside of the head 42. Subsequently, the re~-in;ng portion of the blank is shaped partly around the head so that the cap 50 may not fall off the bolt 38.
Inserting the nail shaft 10 is performed when the straddling member 36 is mounted, wherein the threaded portion 44 is received by the internal thread 18 of the pro~; -1 end portion 12 and the cap 50 is partly located outside of the nail 10. Driving in the nail by a driving unit which co-208~601 operates with the distal nail end 20 and which engages therecesses 28, 30, is initially started in a position in which the plane of the curvature of the nail qhaft i9 offget approximately 90~ with respect to the natural cur~ature of the spoke bone. During the driving process, the nail shaft is rotated about approximately 90~ by means of the driving device. Subsequently, the nail reaches a distal position in which the flats 24, 26 extend approximately parallel to the back of the hand. Driving in may be performed by a lance which has been driven before into the spoke bone. For this the screw bolt 38 has a through-bore 48. After the nail shaft 10 has been driven in and properly positioned, the screw bolt 38 is rotated by insertin~ a tool through the hollow nail shaft lO. The tool cooperates with the hexagon 48. In axially displacing the bolt, the conical face 52 expands the distal end portion 12 to proximally anchoring the nail 10. Then the position of the cross bore 20 is determined by a positioning unit to provide a bore in the bone to fix a bone screw which is preferably inserted close to the distal end of the cross bore 22 . Tnrn i ng a screw not shown in the internal thread 32, the screw presses against the bone screw in the cross bore 22 to c~ ess the bone fragments.
The positioning device may cooperate with the axial recesses 28, 30 to obtain a proper rotational position with respect to the nail shaft 10.
The outer diameter of the nail shaft 20 is preferably 5 or 6 mm and the inner diameter about 2.5 to 4 mm. The length may be 170 to 250 mm in steps of 10 mm, for example. The length is preferably selected such that straddling is performed in the area of the tuberositas radii which is a relati~ely strong section of the spoke bone. Further, the nail cross-section is approximately oval to facilitate the forming of the proxi~l nail end.
