Intramedullary Nail & Locking Screws System is a gold-standard orthopedic trauma implant solution for internal fixation of long bone fractures, including femur, tibia, humerus, fibula, ulna and radius fractures. It consists of intramedullary nails, lag compression screws, interlocking locking bolts and end caps. The intramedullary nail is inserted inside the medullary canal of long bones. Combined with proximal and distal locking screws, it delivers angular stability, prevents rotation and shortening of fractured bone segments. Compared with traditional plate fixation, intramedullary nailing is minimally invasive, preserves periosteal blood supply, and accelerates bone healing.
Changzhou Waston Device manufactures a full portfolio of intramedullary nail and locking screw systems for global orthopedic hospitals and medical distributors. Our product line covers GAMMA PFNA, tibial intramedullary nail (standard & patellar entry type), humeral nail, fibular nail, ulna & radius retrograde nail, flexible retrograde nail for pediatric and upper limb fracture management.
1. GAMMA PFNA (Gamma Intramedullary Nail) Our PFNA system includes standard and extra-long PFNA variants, specially designed for proximal femoral fractures, intertrochanteric and subtrochanteric femur fractures. It features patented clamping structure: clamps do not need replacement for different nail diameters. The multi-in-one aiming device simplifies intraoperative positioning. Special manufacturing technology minimizes spring-back for precise implantation. Sizes available in diameters 9.2mm,10mm,11mm,12mm with multiple length options.
2. Tibial Intramedullary Nail (X Series & Patellar Entry Type) X series tibial nails apply to tibial shaft, metaphyseal, tibial plateau and Pilon fractures. Patellar entry tibial nails are indicated for proximal lateral tibial shaft fracture, comminuted tibial fractures, and cases with limited knee flexion. Diameter range: 8.5mm,9mm,10mm,11mm.
3. Humeral Self-locking Intramedullary Nail I For proximal humerus and humeral shaft fractures. Matched with 5.0mm and 3.5mm locking screws for different proximal and distal locking holes.
4. Universal Retrograde Nail: Fibular Nail, Ulnar & Radius Nail Fibular intramedullary nail for fibular shaft fracture. Ulnar & radius retrograde nail for forearm long bone fracture, paired with self-tapping locking screws.
5. Flexible Retrograde Intramedullary Nail Suitable for pediatric long tubular bone fractures, adult clavicle and upper limb fractures. Available in small diameters from 2.0mm to 4.0mm.
Waston provides a complete matching locking screw portfolio:
· Distal Locking Bolt (VI type): Ø5.0, length 26–100mm
· Locking Screw II / III type: Ø2.0, Ø2.7, Ø3.5, Ø4.5 for upper limb & tibial fixation
· Lag Compression Screw (III / V type): for PFNA proximal anti-rotation and compression fixation, Ø7.0 and Ø10.0 All locking screws follow 2mm or 5mm incremental size specifications to fit diverse anatomical demands.
Multiple end cap types (III, IV, V, VI, VII, IX, X) for different nail series, used to seal the nail end and reduce soft tissue irritation.
1. Patented Aiming Mechanism Multi-in-one aiming device, no need to change clamps for different nail diameters, saves operation time and reduces intraoperative radiation exposure.
2. Low Spring-back Performance Advanced manufacturing process controls spring-back, maintaining nail shape and stable fracture reduction after implantation.
3. Comprehensive Size Matrix Full range of diameters and lengths for left/right anatomical matching, covering adult, pediatric, standard and long bone trauma cases.
4. Full Set Matching Implants Complete kit: nail, lag screw, locking bolt and end cap in one system. Distributors and hospitals can source one-stop orthopedic trauma implants.
5. Biocompatible Titanium Alloy Material Made of medical titanium alloy, excellent biocompatibility, high fatigue resistance, suitable for permanent or optional hardware removal.
· Proximal femur fracture (intertrochanteric, subtrochanteric fractures, treated by PFNA)
· Femoral shaft fractures
· Tibial shaft, metaphyseal, plateau and Pilon fractures
· Humeral shaft and proximal humeral fractures
· Fibula, ulna and radius long bone fractures
· Pediatric long tubular bone fractures, clavicle fractures
PFNA (Gamma nail) is designed for proximal femur hip fractures, with integrated lag screw for anti-rotation and compression. Tibial nails are used for lower leg fractures, available in patellar entry or conventional entry design, without hip lag screw structure.
Our intramedullary nails and locking screws adopt medical grade titanium alloy, featuring high strength, corrosion resistance and good biocompatibility.
