Treatment of nonunions

Connolly et al. 1991 [49]Atrophic pseudarthrosisPercutaneous autologous bone marrow injection20Healing capacity comparable to autologous cancellous bone grafting

Garg et al. 1993 [50]Nonunion in long bonesPercutaneous autologous bone marrow injection2017 out of 20 cases united in 5 months

Kettunen et al. 2002 [51]Tibially delayed or non-unionPercutaneous autologous bone marrow injection41Appeared to be as effective as open techniques

Hernigou et al. 2005 [52]Atrophic pseudarthrosisPercutaneous autologous bone marrow injection60Application is effective and safe Positive correlation between number of progenitor cells and callus volume

Goel et al. 2005 [53]Tibial non-unionPercutaneous autologous bone marrow injection2015 out of 20 patients showed bone union

Treatment of osteonecrosis

Hernigou and Beaujean 2002 [54]Osteonecrosis femoral headInjection of autologous bone marrow concentrate116 (189 hips)Very good results in early stages Injection of greater number of progenitor cells transplanted had better outcomes

Gangji et al. 2004 [55]Osteonecrosis femoral headInjection of autologous bone marrow concentrate13 (18 hips)Significant reduction of pain, progression and improvement of function

Hernigou et al. 2009 [56]Osteonecrosis femoral headInjection of autologous bone marrow concentrate342 (534 hips)High amount of progenitor cells as predictor for successful outcome

Enhancing spinal fusions

Neen et al. 2006 [57]Spinal fusionsAutologous bone marrow aspirate on hydroxyapatite-collagen I-composite50Similar healing capacity as autologous cancellous bone grafting in posterolateral fusion Inferior results in interbody fusions

Gan et al. 2008 [58]Spinal fusionsBone marrow concentrate on tricalciumphosphate41After 34.5 months 95.1% cases showed good spinal fusion

Filling bone cysts

Wright et al. 2008 [59]Simple bone cystsIntralesional injection of autologous bone marrow aspirate77Inferior results compared to injection of methylprednisolone

Park et al. 2008 [60]Simple bone cystsImplantation of autologous bone marrow aspirate implanted in combination with either nonvital allogenic bone graft or injected with bone powder20 (23 cysts)Injection of bone marrow-bone powder mix is effective alternative to open treatment

Zamzam et al. 2009 [61]Simple bone cystsPercutaneous autologous bone marrow injection28Application is a safe and effective treatment

Filling of bone defects

Salama and Weissman 1978 [62]Different bone defectsXenograft with bone marrow aspirate28Results have been “most satisfactory”

Jäger et al. 2009 [63]volumetric bone deficiencieslocal autologous bone marrow/mesenchymal stem cell injection10May be a promising alternative to autogenous bone grafting

Marcacci et al. 2007 [64]Large bone diaphysis defectautologous MSCs were expanded in vitro and seeded on hydroxyapatite scaffolds4Followup up to 7 years after surgery, good integration of implant, no secondary fractures

Various applications

Hendrich et al. 2009 [65]various bone healing disturbancesBone marrow concentrate101Autogenous bone marrow concentrate application is safe

Giannini et al. 2009 [66]Osteochondral talus defectsarthroscopic-assisted injection of autologous bone marrow aspirate48Functional improvement

Dallari et al. 2007 [67]High tibial osteotomyLyophilized bone chips with platelets-enriched plasma with bone marrow aspirate33Lyophilized bone chips with platelets-enriched plasma with or without bone marrow aspirate enhance healing

Kitoh et al. 2009 [68]femoral and tibial lengtheningsApplication of MSC expanded in vitro with PRP28 (51 osteotomies)No enhancement of bone healing by MSC/PRP
