Hand Instruments Alongside Power Tools
While powered drills, saws, and reamers dominate discussions of orthopedic equipment, a set of hand-driven bone instruments remains essential in nearly every orthopedic case, used for finer bone shaping, removal, and preparation work that powered tools are not suited for. Understanding these instruments by function makes them far easier to recall than trying to memorize an undifferentiated list.
Osteotomes and Chisels
Osteotomes are flat, sharpened instruments struck with a mallet to cut or split bone along a controlled plane, commonly used in procedures requiring a precise bone cut where a powered saw would be imprecise or where access is too limited for a saw blade. Chisels are similar in function but typically have a beveled edge on only one side, allowing for more directional control when shaping bone rather than making a straight cut through it. Both require a mallet, and the surgical technologist must anticipate the striking rhythm and hand the mallet with the correct timing and grip orientation.
Curettes
Curettes have a spoon-shaped, sharpened cup at the tip used to scrape and remove soft or damaged bone, cartilage, or tissue from a bony surface or cavity, commonly used in procedures addressing bone cysts, cartilage debridement in joint surgery, or preparing a bone surface before grafting. Curettes come in a range of cup sizes and angles, and the surgical tech should anticipate which size the surgeon needs based on the size of the defect or cavity being addressed.
Bone Rongeurs
Bone rongeurs, distinct from the softer-tissue rongeurs used in neurosurgery, have heavy, sharp-edged jaws designed specifically to bite through and remove chunks of bone, commonly used to trim bone edges, remove bone spurs, or reshape a bony surface during joint replacement or spine surgery. Double-action rongeurs, which use a compound leverage mechanism, provide significantly more cutting force than single-action designs, making them suited for denser or thicker bone.
Bone Tamps and Impactors
Bone tamps and impactors are used to seat implants or bone graft material firmly into place using controlled mallet strikes, distributing force evenly to avoid fracturing surrounding bone. These are especially common in joint arthroplasty procedures where implant components must be firmly and precisely seated into prepared bone.
- Osteotomes and chisels create controlled bone cuts using mallet-driven force
- Curettes scrape and remove soft or damaged bone and cartilage from a defect
- Bone rongeurs bite through and remove bone chunks, with double-action designs offering more force
- Bone tamps and impactors seat implants and graft material without fracturing surrounding bone
Maintaining Sharp Instruments
Unlike many general surgery instruments, osteotomes, chisels, and bone-cutting rongeurs depend heavily on maintaining a genuinely sharp cutting edge to function safely and effectively, since a dull bone-cutting instrument requires the surgeon to apply more force to achieve the same cut, increasing the risk of the instrument slipping or the bone fracturing in an uncontrolled way. Sterile processing departments typically inspect these instruments for edge sharpness as part of routine quality checks, and the surgical technologist should flag any instrument that feels notably dull or damaged during a case rather than continuing to use it and hoping it performs adequately.
Because these instruments see repeated, high-force use across many cases, they also have a defined service life and require periodic sharpening or replacement as part of a facility's instrument maintenance program, a detail that connects directly to the broader sterile processing and instrument lifecycle management discussed elsewhere in our content.

Surgical technologists who develop a feel for how a well-maintained bone instrument should perform, through repeated hands-on use, often become an informal early-warning system for a facility's instrument maintenance program, noticing subtle performance degradation before it becomes obvious enough to trigger a formal inspection flag, a valuable form of practical expertise that develops specifically through sustained orthopedic case experience.
Hand Skills That Complement Powered Technology
Even as powered orthopedic equipment continues to advance, these fundamental hand instruments remain genuinely essential, and developing strong competency with them provides a foundational skill set that complements rather than becomes obsolete alongside newer powered technology discussed elsewhere in our equipment content.
Surgical technologists who master both hand and powered orthopedic instrumentation develop the most complete, versatile skill set for supporting the full range of techniques a given orthopedic surgeon might employ across different cases and situations.
