An intramedullary system configured to stabilize a bone, the system comprising: - an intramedullary nail having: - a body elongated along a first axis, the body having a proximal portion and a distal portion; - a first aperture formed in the proximal portion, the first aperture defining a second axis transverse to the first axis at a first angle; - a second aperture formed in the proximal portion, the second aperture defining a third axis transverse to the first axis at a second angle, the third axis intersecting with the second axis at the first axis and the first and second angles being complementary angles totalling 180 degrees; and - at least one proximal medial-lateral opening (321, 323) configured to receive a locking screw; and - a headless fastener extending from a first end to a second end, - the headless fastener being blind such that the screw is fully threaded and has no head projecting past a major diameter of the screw thread and/or being a screw or fastener having a head portion where the thread extends all the way to the head, which may be a threaded head, - the headless fastener having a shaft configured to be positioned through the first aperture or the second aperture and the first end of the headless fastener configured to be positioned against or within the bone, - wherein the first aperture radially offset, when the intramedullary nail is disposed in the bone, from the sagittal plane of the intramedullary nail disposed in the bone by a first degree (θ 1) - and the second aperture is radially offset, when the intramedullary nail is disposed in the bone, from the sagittal plane of the intramedullary nail disposed in the bone by second degree (θ 2) which is larger than the first degree (θ 1). - an intramedullary nail having: - a body elongated along a first axis, the body having a proximal portion and a distal portion; - a first aperture formed in the proximal portion, the first aperture defining a second axis transverse to the first axis at a first angle; - a second aperture formed in the proximal portion, the second aperture defining a third axis transverse to the first axis at a second angle, the third axis intersecting with the second axis at the first axis and the first and second angles being complementary angles totalling 180 degrees; and - at least one proximal medial-lateral opening (321, 323) configured to receive a locking screw; and - a headless fastener extending from a first end to a second end, - the headless fastener being blind such that the screw is fully threaded and has no head projecting past a major diameter of the screw thread and/or being a screw or fastener having a head portion where the thread extends all the way to the head, which may be a threaded head, - the headless fastener having a shaft configured to be positioned through the first aperture or the second aperture and the first end of the headless fastener configured to be positioned against or within the bone, - wherein the first aperture radially offset, when the intramedullary nail is disposed in the bone, from the sagittal plane of the intramedullary nail disposed in the bone by a first degree (θ 1) - and the second aperture is radially offset, when the intramedullary nail is disposed in the bone, from the sagittal plane of the intramedullary nail disposed in the bone by second degree (θ 2) which is larger than the first degree (θ 1).
