Item Side-to-Side Metacarpal Fusion for Reconstruction of Bone Loss in the Radial Carpometacarpal Joints(Elsevier, 2021-07-28) Wu, Gerald J.; Loewenstein, Scott N.; Adkinson, Joshua M.; Surgery, School of MedicineWe present a unique case of side-to-side metacarpal fusion for reconstruction after an isolated gunshot wound to the right hand of a 19-year-old woman. There was a traumatic segmental loss of the proximal right second metacarpal base with considerable comminution of the trapezium and trapezoid. Reconstructive options were limited because of the destruction of the distal carpus and carpometacarpal (CMC) joint. Digital ray amputation was offered but deferred because of patient preference. The reconstruction was performed via metacarpal fusion of the second metacarpal remnant to the third metacarpal base, bypassing the previously destroyed second CMC joint. The fusion of the second and third metacarpals offers acceptable results when the radial CMC joints are traumatized with extensive bone loss.Item Successful Arthrodesis Using a Blended Allograft and Autograft Mixture in Lumbar Interbody Fusion: A Retrospective Case Series(Springer Nature, 2024-09-15) Fiechter, Jay; Baumann, Anthony N.; Smith, Micah; Orthopaedic Surgery, School of MedicineIntroduction: Achieving successful arthrodesis after lumbar interbody fusion remains a challenge, especially for minimally invasive surgical approaches that limit the amount of local bone autograft. However, using an allograft blend as an autograft extension mixture may hold promise but requires further research. The purpose of this study is to examine the impact of an allograft blend added to autograft on the quality of arthrodesis after lumbar interbody fusion in adult patients. Methods: This study is a retrospective case series of adult patients (>21 years old) who underwent lumbar interbody fusion between October 2021 and January 2022, performed by a single spine surgeon. The quality of arthrodesis was assessed via the Bridwell grade (I-IV) for up to six months. The impact of surgical technique, age, sex, or amount of allograft utilized during fusion on Bridwell grade was assessed. Results: Patients (n = 18; 27 levels fused) had a mean age of 58.6 (1.9) years and a mean BMI of 32.8 (1.2) kilograms per meter squared (kg/m²). A mean of 18.0 (standard deviation = 2.4) cubic centimeters (cc) (range: 3.4-50.0 cc) of allograft was used per fused level. A Bridwell grade of I (successful arthrodesis) was achieved at three months in 11.1% (3/27) of fusions and at six months in 85.2% (23/27) of fusions. Four fusions remained at a Bridwell grade of II at six months and subsequently achieved complete arthrodesis at 12 months. No patients received a Bridwell grade of IV (lucency with collapse of graft) at three- or six-month follow-up. There was no difference in Bridwell grade when stratified by surgical technique, age, sex, or amount of allograft used. Conclusion: The allograft and autograft blend utilized in this study resulted in successful arthrodesis at all fused levels after one year, irrespective of surgical technique or other patient factors. Prospective studies with larger sample sizes are needed to corroborate the findings of this small case series.
