摘要： A compression pin (10) for urging two bone regions (12A) (12B) together includes a pin body (14) having a distal end (220), an opposed proximal end (222), a first threaded region (216), and a second threaded region (218). The first threaded region (216) is positioned near the distal end (220), and the second threaded region (218) is positioned near the first threaded region (216). The first threaded region (216) includes a first thread (228) having a FT leading surface (242F) that is at a FT leading angle (248F), and the second threaded region (218) includes a second thread (230) having a ST leading surface (242S) that is at a ST leading angle (248S) that is different than the FT leading angle (248F). Additionally, the first thread (228) includes a FT trailing surface (244F) that is at a FT trailing angle (246F), and the second thread (230) includes a ST trailing surface (244S) that is at a ST trailing angle (246S) that is different than the FT trailing angle (246F). Moreover, the first thread (228) has a first thread shape and the second thread (230) has a second thread shape that is substantially opposite to the second thread shape. With this design, during insertion of the compression pin (10), the first threaded region (216) and the second threaded region (218) cooperate to aggressively compress the bone regions (12A) (12B) together.

摘要： A snap-off screw (10) for insertion into one or more two bone regions (12A) (12B) includes a screw body (14) having a screw region (16) and a driver region (18). Upon insertion of the screw region (16), the driver region (18) is designed to be decoupled from the screw region (16). The screw region (16) includes a screw distal end (224), an opposed screw proximal end (226), a threaded area (228), and a head area (232) positioned at the screw proximal end (226). The driver region (18) includes a driver attachment end (238) and an opposed driver distal end (240). The driver attachment end (238) is coupled to the screw region (16) between the screw distal end (224) and the screw proximal end (226). With this design, when the driver region (18) is decoupled from the screw region (16), a screw break surface (460) is positioned below a portion of the head area (232) of the screw region (16). As a result thereof, the screw break surface (460) does not provide an area of irritation for soft tissue around the inserted snap-off screw (10).
摘要翻译：用于插入到一个或多个两个骨区域（12A）（12B）中的卡扣螺钉（10）包括具有螺钉区域（16）和驱动器区域（18）的螺钉体（14）。在插入螺钉区域（16）时，驱动器区域（18）设计成与螺钉区域（16）分离。螺钉区域（16）包括螺钉远端（224），相对的螺钉近端（226），螺纹区域（228）和位于螺钉近端（226）处的头部区域（232）。驱动器区域（18）包括驱动器附接端（238）和相对的驱动器远端（240）。驱动器附接端（238）联接到螺杆远端（224）和螺钉近端（226）之间的螺钉区域（16）。通过这种设计，当驱动器区域（18）与螺钉区域（16）脱离时，螺钉断裂面（460）位于螺钉区域（16）的头部区域（232）的一部分的下方。其结果是，螺钉断裂面（460）不会对插入的拔出螺钉（10）周围的软组织产生刺激的区域。

摘要： A compression pin for compressing two bone regions together includes a body having a distal end, a proximal end, a first threaded region, and a second threaded region. The first region is positioned near the distal end, with the second region positioned near the first region. The first region includes a first thread having a leading surface at a first leading angle, and a trailing surface at a first trailing angle. The second region includes a second thread having a leading surface at a second leading angle, and a trailing surface at a second trailing angle, each respective second angle different from the respective first angle. The first thread has a first thread shape and the second thread has a second thread shape that is substantially opposite to the first thread shape. During insertion of the pin, th first region and second region cooperate to compress the bone regions.
