Clinical and Radiologic Outcomes of the Matti-Russe Technique for Scaphoid Nonunions in Pediatric Patients.

ABSTRACT:

Background

Scaphoid fractures are a common injury, and a known complication is nonunion. One option to treat this nonunion is with the Matti-Russe technique, which takes a corticocancellous graft and fits it into the defect without internal fixation. The advent of modern methods of fixation has led the classic Matti-Russe technique to fall out of favor. In this study, we describe the classic technique and evaluate the results of the Matti-Russe method for treatment of scaphoid nonunions specifically for the pediatric population. Our purpose was to evaluate the long-term clinical and radiologic outcomes after surgery for scaphoid nonunion using the Matti-Russe technique in the pediatric population.

Methods

A retrospective review was performed of patients less than 17 years of age, with a scaphoid nonunion that was treated with the Matti-Russe technique. This technique consisted of open reduction with intercalated bone graft and no internal fixation with hardware. Union was determined by radiographic evaluation. Computed tomography was obtained in 7 of 10 patients in this series and showed bony bridging in more than 50% of the scaphoid width in 3 different views. Intrascaphoid, scapholunate, and radiolunate angles were calculated. We reviewed wrist range of motion and complications. We obtained postoperative Mayo and Disabilities of the Arm, Shoulder and Hand (DASH) scores.

Results

There were 10 patients who underwent the Matti-Russe technique. The average age was 14.7 years old (±1.34, range: 13-17). All 10 of these patients had a scaphoid waist nonunion. There were 9 males and 1 female with an average follow-up of 13 months. The average amount of time to surgery from the date of injury was 12.3 months. All 10 patients went on to radiographic union at or before 6 months from surgery. Preoperative intrascaphoid, scapholunate, and radiolunate angles were 29° (±5.38), 62° (±18.28), and 20° (±9.22). Postoperative intrascaphoid, scapholunate, and radiolunate angles improved to 16° (±6.89), 38° (±8.50), and 10° (±4.69), which was significant. Seven out of 10 patients completed postoperative outcomes measures. The average postoperative Mayo wrist score was 87.9 (±14.10, range: 60-100). The average postoperative DASH score was 1.9 (±2.03, range: 0-4.5). There were no associated complications nor reoperations.

Conclusion

The Matti-Russe technique is a safe and effective treatment for scaphoid nonunion in the pediatric population. It facilitates scaphoid union without the need for screw fixation and avoiding potential complications with hardware.

Project description:BackgroundFree vascularized medial femoral condyle (MFC) bone grafts can lead to increased vascularity of the proximal pole and restore scaphoid architecture in scaphoid nonunions. The intraoperative perfusion assessment of the bone graft is challenging because the conventional clinical examination is difficult. Indocyanine green (ICG) angiography has previously been shown to provide a real-time intraoperative evaluation of soft tissue perfusion in reconstructive surgery. The present study investigated the utility of ICG angiography in patients treated with a free medial femoral condyle graft for scaphoid nonunions.MethodsWe performed a retrospective analysis of patients with scaphoid nonunions, in which ICG angiography was used intraoperatively for perfusion assessment. The medical records, radiographs, intraoperative imaging, and operative reports of all patients were reviewed. Intraoperative ICG dye was administered intravenously, and laser angiography was performed to assess bone perfusion. The scaphoid union was examined using postoperative CT scans.ResultsTwo patients had documented osteonecrosis of the proximal pole at the time of surgery. Four patients received a nonvascularized prior bone graft procedure, and a prior spongiosa graft procedure was performed in one patient. The mean time from injury to the MFC bone graft surgery was 52.7 months, and the mean time from prior failed surgery was 10.4 months. Perfusion of the vascular pedicle of the MFC and the periosteum could be detected in all patients. In two patients, even perfusion of the cancellous bone could be demonstrated by ICG angiography. Following transplantation of the bone graft, patency of the vascular anastomosis and perfusion of the periost were confirmed by ICG angiography in the assessed cases. No additional surgery regarding a salvage procedure for a scaphoid nonunion advanced collapse was necessary for the further course.ConclusionICG-angiography has shown to be a promising tool in the treatment of scaphoid nonunion with medial femoral condyle bone grafts. It enables intraoperative decision making by assessment of the microvascular blood supply of the periosteum and the vascular pedicle of the MFC bone graft. Further studies need to evaluate the impact on union rates in a long-term follow-up.

Project description:BACKGROUND: The ideal treatment of nonunion of the scaphoid remains unresolved and controversial. It was hypothesized that scaphoid nonunion could be treated successfully using a closed-wedge osteotomy of the distal radius which reduces the inclination of the joint surface and decreases the pressure between the radial and scaphoid surfaces with a reduction of the force applied by the styloid process. We present a preliminary report in six patients with nonunion of the carpal scaphoid using this procedure. The main objective of the osteotomy is to achieve fusion, alleviate pain, and improve function. MATERIALS AND METHODS: Six closed-wedge osteotomies to reduce the inclination of the distal radial surface were performed in patients with scaphoid waist nonunion and a viable proximal pole, without posttrauma osteoarthritis or with moderate posttraumatic osteoarthritis confined to the radio-scaphoid joint. The present series of six patients (all men) were followed for at least 8 months (mean follow-up 14.2 months, range 8-21 months). RESULTS: Solid union was achieved in five patients. Postoperatively, three patients were pain-free, two presented mild pain for heavy work, and one had moderate pain. This type of osteotomy reduced the inclination of the joint surface (radial angulation) 6.2 degrees on average. There was an improvement in joint flexion from a preoperative mean of 40 degrees to 52.5 degrees at last follow-up, in extension from 40.8 degrees to 66.7 degrees , in radial deviation from 15 degrees to 22.5 degrees , and in ulnar deviation from 30.8 degrees to 41.7 degrees . CONCLUSIONS: This preliminary study suggests that a closed-wedge osteotomy of the distal radius could be an alternative approach for patients with scaphoid waist nonunion and a viable proximal pole, without posttrauma osteoarthritis or with moderate posttraumatic osteoarthritis confined to the radio-scaphoid joint. The number of cases was small; however, further studies with a much larger series are needed before routine use of wedge osteotomy in scaphoid nonunion can be recommended.
