Clinical application cases of absorbable bone plates
Metacarpal fracture: A 34-year-old male patient suffered a fracture of the fourth metacarpal bone in his left hand due to trauma. He was admitted to the hospital for open reduction and internal fixation of the fracture. During the operation, a small absorbable bone plate was used, along with 2.0 absorbable screws. Postoperative X-ray observation showed that the fracture had recovered well.
Metatarsal bone fracture: A 46-year-old female patient was admitted to the hospital for examination due to foot sprain. X-ray showed a fracture of the third metatarsal bone. Open reduction of the fracture and internal fixation with absorbable nails were performed. During the operation, a small bone plate was used in combination with 2.0mm absorbable nails. Postoperative observation showed good reduction.
Hallux valgus correction: A 60-year-old female patient suffered from outward deviation of both big toes for over 20 years without treatment. Later, she developed pain on the inner side of both big toes and restricted her ability to wear shoes. She was admitted to the hospital for further treatment and underwent osteotomy and internal fixation with absorbable screws. During the operation, a 2.7mm absorbable screw was used for fixation. Another 57-year-old female patient was admitted to the hospital due to a similar condition and was fixed with a 4.5mm absorbable screw during the operation.
Distal fibular fracture: A 26-year-old female patient suffered a distal fracture of the left fibula due to a fall while cycling. After admission, she underwent open reduction of the fracture and internal fixation with absorbable bone plates. During the operation, 3.5mm bone screws and large bone plates were used. Immediate postoperative X-ray showed good fracture reduction.
Internal malleolus fracture: A 16-year-old female patient was admitted to the hospital for examination due to left ankle sprain. After admission, she underwent open reduction and internal fixation with absorbable screws, during which two 3.5mm semi-threaded bone screws were used.
A 8-year-old female patient suffered a fracture of the small bone of the left radius with epiphyseal injury due to a fall. She was admitted to the hospital for open reduction and internal fixation with absorbable nails. During the operation, two 2.0 unthreaded bone rods were used for fixation. Postoperative observation showed that the range of motion of the joint was good.
Fracture of the right radius: A 4-year-old male patient suffered a fracture of the right radius. During the operation, a medium-sized absorbable bone plate was used in combination with a 2.7mm bone screw. Postoperative X-ray observation showed that the fracture was well aligned and aligned, and the implant was firmly fixed.
Maxillofacial fractures: In the treatment of maxillofacial fractures, absorbable bone plates also play a significant role. For instance, under 3D printing navigation, doctors can print out a three-dimensional model of the patient’s head based on their CT data, visually presenting the fracture situation, and use mirroring technology to print out a model of the fracture area. Before the operation, based on the surgical plan and the degree of fracture, the shape of the bone plate can be absorbed during the preforming surgery, making the bone plate more closely adhere to the bone surface. During the operation, the doctor matched the 3D printed model with the intraoperative dynamic navigation system, reduced the fracture fragments, and then made a minimally invasive incision along the natural folds in the oral cavity. The fracture ends were fixed with absorbable bone plates, and the reduction effect was confirmed by intraoperative fluoroscopy.
Ankle fracture: A 58-year-old female patient was admitted to the hospital with a diagnosis of right medial and lateral malleolus fracture accompanied by ankle dislocation due to trauma causing injury to the right ankle joint. The patient did not want to undergo a second operation to remove the metal internal fixation and chose an absorbable nail plate for the operation. With the cooperation of the anesthesiology department, the operation was successfully completed. Postoperative X-rays showed that the fracture and joint had achieved clinical reduction.
