A bone curette is a spoon-shaped scraping instrument used to remove soft tissue, necrotic bone, cysts and cartilage from bone cavities and joint surfaces. Volkmann and Bruns patterns are the two names purchasing teams meet most often. This guide explains cup shape and size, straight and angled versions, spinal curettes and the practical checks that matter when you order.
What a bone curette is used for
A curette has a handle, a shaft and a cup with a sharp or semi-sharp rim. Pulled toward the surgeon, it scrapes tissue out of a cavity. Typical uses are debridement of infected or necrotic bone, curettage of bone cysts and benign lesions, harvesting cancellous bone graft from the iliac crest, preparing joint surfaces and clearing disc material and endplate cartilage in spine surgery.
Because it is a scraping rather than a cutting tool, a curette is chosen for control: the cup size and the rim determine how much tissue is removed per stroke.
Volkmann bone curette and Bruns curette
The Volkmann bone curette, often called a Volkmann spoon, is the classic orthopaedic scoop, commonly double-ended with a different cup size on each end. The cup is oval or round, with a sharp rim for scraping bone. The Bruns bone curette is a related long-handled design with a similar spoon.
REDA lists Bruns and Volkmann bone curettes in its orthopaedic instrument section, alongside osteotomes, rongeurs, bone levers and elevators. If you are building a full tray, read orthopaedic instruments names and uses.
Curette sizes: cup width, rim and fenestration
Curette sizes are normally given by cup size, from very small cups for delicate cavities to large cups for rapid removal. Catalogues may use a number scale or the inner diameter in millimetres. Because systems differ, quote the measurement in millimetres and check it against the manufacturer's drawing.
Rims can be sharp, for cutting through firm tissue, or blunt, for controlled scraping where bone must be preserved. Some cups are fenestrated, which allows tissue to pass through and keeps the cavity visible. Choose by procedure rather than by habit.
- Cup size in millimetres: small, medium and large in every set
- Rim: sharp for bone and cysts, blunter for delicate surfaces
- Cup shape: oval, round or fenestrated
- Single-ended or double-ended
- Overall length for the depth of the wound
Straight, angled and spinal curettes
Straight curettes work well in accessible cavities. Angled curettes, with the cup set at an angle to the shaft, reach around corners, such as the inside of a long bone or a disc space. Spinal curettes are slim, long-shafted and often angled up or down so that the cup meets the endplate, while some are ring-shaped or cup-shaped depending on technique.
A spine set should include several cup sizes and at least some angled options so that the endplates can be prepared without damaging the vertebral body. See the related spine surgery instrument set and the Kerrison rongeur used together in many decompressions.
Quality checks, sharpening and reprocessing
Check that the rim is smooth and continuous, that the cup is not distorted and that the handle is solidly joined to the shaft. A blunt rim tears tissue rather than scraping it and needs resharpening, so plan to inspect curettes regularly.
Cups and fenestrations trap bone and tissue, so reprocessing requires brushing and flushing before sterilisation. Request the manufacturer's cleaning instructions and make sure they fit your washer-disinfector. See instrument repair and sharpening for service planning. Keep a record of cup sizes in each set so that a missing or worn curette can be replaced like for like.

Frequently asked questions
What is a Volkmann bone curette?
It is a spoon-shaped scraper, often double-ended with two cup sizes, used to remove diseased bone, cysts and soft tissue and to harvest cancellous bone.
How are bone curette sizes expressed?
Usually by the cup size, either on a numbered scale or as the inner width in millimetres. Check the measurement against the manufacturer's drawing.
When is a spinal curette needed?
Spinal curettes are slim, long and often angled, so they can clear disc material and prepare vertebral endplates through a narrow approach.
Should a bone curette have a sharp or blunt rim?
Sharp rims remove firm tissue and bone efficiently, while blunter rims give controlled scraping on delicate surfaces. Most sets include both.
