BACKGROUND

This disclosure relates to surgical devices and methods for repairing bone defects.

Many bones of the human musculoskeletal system include articular surfaces. The articular surfaces articulate relative to other bones to facilitate different types and degrees of joint movement. The articular surfaces can erode (i.e., experience bone loss) over time due to repeated use or wear or can fracture as a result of a traumatic impact. These types of bone defects can cause joint instability and pain.

Bone deficiencies may occur along the articular surfaces of the glenoid bone. Some techniques utilize a bone graft and/or implant to a fill defect in the glenoid bone. A reamer may be utilized to form a recess in the bone dimensioned to receive the bone graft or implant.

SUMMARY

This disclosure relates to surgical devices and methods. The surgical device may be used during methods for repairing bone defects. The surgical devices described herein may be utilized to form a recess or otherwise shape a surface at a surgical site.

A reaming assembly for preparation of a surgical site according to an embodiment of the present disclosure includes, inter alia, a housing defining a passageway that extends along a longitudinal axis, a rotatable drive shaft at least partially received in the passageway, a reaming head pivotably coupled to a reaming carrier, the reaming carrier operably coupled to the drive shaft, the reaming head including a plurality of teeth rotatable about a reaming axis, and at least one control block including a block body having a control surface and a through bore extending from the control surface along a block axis. The at least one control block is dimensioned to slidably engage the housing along an interface to secure the at least one control block such that the control surface faces away from a distal end portion of the housing, the through bore is dimensioned to at least partially receive the reaming carrier, the control surface is non-orthogonal relative to the block axis such that a reaming angle is defined between the longitudinal axis and the reaming axis, and the reaming head is rotatable along the control surface to remove bone.

A reaming assembly for preparation of a surgical site according to an embodiment of the present disclosure includes, inter alia, a housing defining a passageway that extends along a longitudinal axis, a rotatable drive shaft at least partially received in the passageway, a reaming head operably coupled to the drive shaft, the reaming head including a plurality of teeth rotatable about a reaming axis, and a head assembly coupled to the housing, the head assembly including a head plate and a drive member, the head plate having a control flange and a plate body having a control surface, and the control flange extending from the plate body and engaging the drive member. The reaming head is rotatable along the control surface to remove bone, and the control flange adjusts an orientation of the control surface relative to the longitudinal axis in response to rotation of the drive member.

A method of use for a reaming assembly to prepare a surgical site in bone according to an embodiment of the present disclosure includes, inter alia, slidably engaging a head assembly along an interface to secure the head assembly to a distal end portion of a housing, wherein the housing defines a passageway that extends along a longitudinal axis, the head assembly defines a through bore extending from a control surface, inserting a reaming carrier into the passageway and the through bore, wherein the reaming carrier is pivotably coupled to a reaming head along the longitudinal axis such that the control surface faces away from the distal end portion of the housing at a non-orthogonal angle relative to the longitudinal axis, and rotating the reaming head along the control surface to remove bone in response to rotating a drive shaft operably coupled to the reaming carrier.
