✓ 100% Fully resorbable <4-8 Weeks> with resorption synchronized to bone regeneration

✓ Promotes Bone Regeneration

Features

1. Optimal Mechanical Strength

Through its patented technology, a uniform and dense columnar crystal structure is formed, enhancing mechanical strength and stability.With compressive strength over four times that of human cancellous bone, it provides robust structural support for bone defects. Its excellent osteoconductivity promotes osteoblast adhesion and new bone ingrowth, facilitating effective bone regeneration.

2. Excellent Safety Profile

No heat is released during setting, avoiding thermal damage to nearby tissues. The material is highly biocompatible and fully resorbs in 2–3 months, matching natural bone healing. Its pure composition breaks down into non-toxic, pH-neutral ions (Ca²+and SO4 ²-), minimizing inflammation, allergy, and surgical risk.

3. Sustained Antibiotic Elution Profile

Optimized pore structure enables precise antibiotic loading and sustained release.This improves local antibiotic concentration and bioavailability while reducing systemic toxicity. Enables infection-specific antibiotic customization, suitable for treating infected fractures, joint infections, and post-tumor bone defects.

4. Quick Setting & Easy Shaping

After mixing for 30–60 seconds, the powder and liquid form a moldable paste within 3 minutes, adaptable to bone defects of various shapes and sizes. The material fully sets within 10–15 minutes, making it ready for implantation and suitable for diverse clinical contouring needs.

Clinical Application Cases

Case 1

Spine - Vertebral Compression Fracture

40 year old female with an L2 compression fractureunderwent pedicle screw and rod fixation. 10 cc AtomMedical Calsium Sulphate paste was applied; at 6months post-op, the material was fully resorbed withnew bone formation and solid vertebral fusion.

Case 2

Joint - Prosthetic Joint Infection Revision

Following prosthesis revision, 30cc of antibiotic-loadedCalcium Sulphate was implanted. After 3-monthfollow-up, the patient remained infection-free with noadverse events observed.

Case 3

Trauma - Infected nonunions of tibia

20 year old male with a one year history of infectiousnon union of the left tibia following internal fixation.During surgery, thorough debridement was performedand Atom Medical Calcium Sulphate mixed with antibi-otic was implanted; at one year post-op, the patientdemonstrated excellent recovery.

Case 4

Bone Tumor - Benign bone tumorof the distal tibia

30 year old male with a benign tumor of the distal tibiaunderwent curettage, followed by implantation of AtomMedical Calcium Sulphate; at 1.5 years post-op, thepatient exhibited excellent recovery.
