Surgical Technique: "Perforate and Fill" Technique of Bone Grafting for Scaphoid Fracture Fixation

We introduce the "Perforate and Fill" technique for bone grafting of scaphoid fracture with delayed union and nonunion, which preserves the cartilage shell and does not break open the fibrous nonunion. This article describes the technique and reports the experience in 11 scaphoid fractures.

The records of 11 patients whose scaphoid fractures were managed surgically with this bone grating technique from our institution from July 2017 to June 2024 were reviewed retrospectively. Patient and fracture factors, radiographic measurements of bone defect, postoperative films, and subjective and objective outcomes were considered.

The radiographic union of the fracture ranges from 36 to 110 days (an average of 68 days). In the last follow-up review, the affected wrists were pain free in all cases, and they were able to resume their premorbid status of vocation and resumed all physical activities. In nine cases, their total wrist motion (including flexion, extension, radial, and ulnar deviation) measured 130° to 195° (an average of 172° and 93% of the opposite wrists). In these nine cases, their grip strengths measured 28-50 kg (an average of 31.5 kg and is 97% of the opposite hand).

In conclusion, in treatment of scaphoid fracture delayed union and nonunion, the "Perforate and Fill" technique of bone grafting is a good alternative to the conventional wedge grafting technique. The advantage of keeping the intact cohesive union of cartilage shell and a less-invasive approach may contribute to the success of the fracture union in our 11 cases using this technique.
