Addition to the Toolbox of Surgical Techniques for Palatal Fistula Repair

In response to the article by Rothermel and colleagues, the authors suggest the use of cancellous bone graft for repair of fistulae of the hard palate as an addition to the proposed toolbox.

The treatment of the atrophic clavicular nonunion by double-plate fixation with autogenous cancellous bone graft: a prospective study

Background The objective of this study is to assess prospectively the effectiveness of double-plate fixation combined with autogenous cancellous bone graft in the treatment for the atrophic clavicular nonunion. Methods Between February 2013 and November 2017, a total of 12 patients with atrophic clavicular nonunion (mean age, 40.4 ± 9.0 years, range, 27–60 years) were treated by double-plate fixation with autogenous cancellous bone graft in our institute. The Constant Score System was used to evaluate the preoperative and final outcomes. The Short Form-36 (SF-36) outcome questionnaire was used to assess the final clinical results. Results All patients were followed-up, with the average follow-up of 34.7 ± 6.7 months (range, 24–48 months). The healing rate was 100% in our study. The mean time of bony union was 9 weeks (range, 8–10 weeks). One patient had a postoperative superficial infection, and the patient was cured by oral antibiotics and wound dressing. No implant-related complications (plate-screw loosening or breakage) were observed postoperatively. No vascular injury, neural impairment, or thoracic outlet syndrome was discovered preoperatively or postoperatively. There is a statistical significance between the preoperative and the postoperative constant scores (P < 0.05). All the patients were satisfied with their final clinical results by SF-36 outcome questionnaire. Average scores of the physical function and bodily pain components of the SF-36 were 94.2 ± 7.3 and 92.5 ± 5.8, respectively. Conclusion Our results presented that double-plate fixation with autogenous cancellous bone graft is an effective treatment for atrophic clavicular nonunion, especially for those with a significant bone defect.

Novel Vacuum-Assisted Method for Harvesting Autologous Cancellous Bone Graft and Bone Marrow From the Proximal Tibial Metaphysis

Background: Autogenous cancellous bone graft and bone marrow aspirate are commonly used in lower extremity fusion procedures to enhance fusion potential, and frequently in revision situations where bone loss and osteolysis may be a feature. The tibial metaphysis is a common donor site for bone graft, with the procedure typically performed using a curette or trephine to harvest the cancellous bone. Some limitations of this technique include suboptimal harvest of the marrow portion in particular, incomplete graft harvest, and loss of graft material during the harvest process. We describe a novel vacuum-assisted bone harvesting device to acquire cancellous bone and marrow from the proximal tibia. Methods: This is a retrospective study of a single surgeon’s consecutive patients who underwent foot and ankle arthrodesis procedures using proximal tibia autograft obtained using a vacuum-assisted bone harvesting device. Descriptive statistics were used to summarize patient and operative characteristics and outcomes. We identified 9 patients with a mean age of 51 years, 4 of whom were female. Results: On average, the skin incision was slightly more than 2 cm, and 27 mL of solid graft and 16 mL of liquid phase aspirate were collected. At 6 weeks after the procedure, there was minimal to no pain at the donor site, and we did not observe any fractures or other complications. Conclusions: We report the use of a novel vacuum-assisted curette device to harvest bone graft from the proximal tibial metaphysis for use in foot and ankle fusions. This device has been reliable and efficient in clinical practice. Level of Evidence: Level IV, retrospective case series.

Arthroscopic Bone Grafting and Kirschner-Wires Fixation for Scaphoid Nonunion

Various surgical techniques, such as corticocancellous or cancellous bone graft and other vascularized bone grafting techniques have been developed to treat scaphoid nonunion. However, open grafting with dissection of wrist capsule and ligaments damages the joint and hence can lead to increased stiffness of the wrist and hand. Arthroscopic assisted bone grafting and percutaneous fixation have advantages such as minimal surgical trauma to the scaphoid blood supply and its ligament connection and provide a thorough wrist assessment, comprehensive approach for scaphoid nonunion and its sequelae in a minimally invasive manner. This article briefly discusses the characteristic anatomy of the wrist and scaphoid, and reviews the technique of arthroscopic bone grafting and percutaneous fixation for the treatment of scaphoid nonunion.
