Fulltext Clinical and radiological results of the vascularized medial femoral condyle graft for scaphoid non-union

Keller M, Kastenberger T, Anoar AF, Kaiser P, Schmidle G, Gabl M, et al.

Arch Orthop Trauma Surg, 2020 Jun;140(6):835-842.
PMID: 32124031 DOI: 10.1007/s00402-020-03386-7

INTRODUCTION: This study evaluated the use of a free vascularized bone graft with and without cartilage from the medial femoral condyle (MFC) in patients with recalcitrant scaphoid non-union, with a special focus on union rates and the osteochondral graft for proximal pole destruction.
MATERIALS AND METHODS: Thirty-eight avascular scaphoid non-unions in 37 patients who were treated with a free osteoperiosteal or osteochondral MFC graft were retrospectively evaluated (mean follow-up 16 months). Bone union, the scapholunate and the radiolunate angles were evaluated on X-ray images. The range of motion, grip strength, VAS, DASH and PRWE scores were evaluated clinically.
RESULTS: The overall union rate was 95%. Bone union was achieved in 27 out of 29 (93%) scaphoids treated with a free osteoperiosteal MFC grafts and in 9 out of 9 (100%) scaphoids treated with a free osteochondral MFC graft. The range of motion remained almost unchanged, while grip strength increased significantly (34 kg vs. 44 kg) and the VAS (22-5), DASH (59-19) and PRWE (62-30) score decreased significantly. The scapholunate (71°-65°) and radiolunate (28°-18°) angle decreased. No major donor site morbidity was observed. Postoperative complications were observed in eight cases (21%).
CONCLUSIONS: The vascularized medial femoral bone graft leads to a good functional outcome in the treatment of scaphoid non-unions. The graft provides adequate blood supply and structural stability to the scaphoid. A proximal pole destruction can be replaced using an osteochondral graft with promising short-term results preventing carpal osteoarthritis and collapse.

Fulltext Bone transport in the management of fractures of the tibia

Thirumal M, Shong HK

Med J Malaysia, 2001 Mar;56(1):44-52.
PMID: 11503296

A review was carried out in 21 cases of bone transport in the tibia done between May 1995 and December 1997. These were done for the treatment of compound (Grade IIIB) fractures with extensive bone and soft tissue loss and in infective non-unions of the tibia using the Ilizarov technique and ring fixator. In 5 cases, 2 or 3 additional procedures were needed such as tendo achilles (TA) lengthening, bone grafting, revision of construct or revision of scar at the docking site. Average resection of infected bone was 5.2 cms in the infective non-union group and average bone and soft tissue loss was 8 cms in the compound Grade IIIB fracture group. The defect was bridged and regenerate bone occurred in all the cases except one. Union was achieved in all the cases although 10 needed bone grafting. Infection was eradicated in all the cases. Limb length discrepancy was corrected in all the cases except three. Mean duration of treatment was 12 months.

Bone processing and radiation were reported to influence mechanical properties of cortical bones due in part to structural changes and denaturation of collagen composition. This comparative study was to determine effects of bone processing on mechanical properties and organic composition, and to what extent the radiation damaging after each processing. Human femur cortical bones were processed by freezing, freeze-drying and demineralisation and then gamma irradiated at 5, 15, 20, 25 and 50 kGy. In the compression test, freeze drying significantly decreased the Young's Modulus by 15%, while demineralisation reduced further by 90% (P bone by 93% (P bones irradiated at 25 and 50 kGy showed by the highest peak of the amide I collagen in the Fourier Transfer Infra-Red spectra indicating more collagen was exposed after calcium was removed in the demineralised bone, however radiation showed no effect on the collagen crosslink. The study confirmed that demineralisation further reduced the ability to resist deformation in response to an applied force in freeze-dried bones due to calcium reduction and collagen composition. Sterilisation dose of 25 kGy has no effect on mechanical properties and collagen composition of the processed human cortical bone.

Fulltext A Novel Technique for Fixation of Non-union Unicondylar Hoffa's Fracture: A Case Report

Harna B, Dutt DD, Sabat D

Malays Orthop J, 2020 Nov;14(3):174-176.
PMID: 33403081 DOI: 10.5704/MOJ.2011.028

Hoffa fractures are rare and difficult fractures to manage. Hoffa fracture involves a coronal plane fracture of posterior femoral condyle. Non-union in Hoffa fracture is further difficult to manage. The surgical management for such nonunion includes open reduction with recon/LCP plate or screw fixation with bone grafting. The problem with plates is the difficulty in contouring the plates according to the shape of posterior femoral condyles. We describe a new technique with 2 L shaped neutralisation plates placed in a circular fashion. This technique provides a more rigid construct and gives better holding strength of screws in Hoffa fragment. This enhances union and mobilisation can be started early.

Current Updates on Bone Grafting Biomaterials and Recombinant Human Growth Factors Implanted Biotherapy for Spinal Fusion: A Review of Human Clinical Studies

Li G, Li P, Chen Q, Thu HE, Hussain Z

Curr Drug Deliv, 2019;16(2):94-110.
PMID: 30360738 DOI: 10.2174/1567201815666181024142354

BACKGROUND: Owing to their great promise in the spinal surgeries, bone graft substitutes have been widely investigated for their safety and clinical potential. By the current advances in the spinal surgery, an understanding of the precise biological mechanism of each bone graft substitute is mandatory for upholding the induction of solid spinal fusion.
OBJECTIVE: The aim of the present review is to critically discuss various surgical implications and level of evidence of most commonly employed bone graft substitutes for spinal fusion.
METHOD: Data was collected via electronic search using "PubMed", "SciFinder", "ScienceDirect", "Google Scholar", "Web of Science" and a library search for articles published in peer-reviewed journals, conferences, and e-books.
RESULTS: Despite having exceptional inherent osteogenic, osteoinductive, and osteoconductive features, clinical acceptability of autografts (patient's own bone) is limited due to several perioperative and postoperative complications i.e., donor-site morbidities and limited graft supply. Alternatively, allografts (bone harvested from cadaver) have shown great promise in achieving acceptable bone fusion rate while alleviating the donor-site morbidities associated with implantation of autografts. As an adjuvant to allograft, demineralized bone matrix (DBM) has shown remarkable efficacy of bone fusion, when employed as graft extender or graft enhancer. Recent advances in recombinant technologies have made it possible to implant growth and differentiation factors (bone morphogenetic proteins) for spinal fusion.
CONCLUSION: Selection of a particular bone grafting biotherapy can be rationalized based on the level of spine fusion, clinical experience and preference of orthopaedic surgeon, and prevalence of donor-site morbidities.

Heterotopic implantation of autologous bone marrow in rock pigeons (Columba livia): possible applications in avian bone grafting

Sanaei MR, Abu J, Nazari M, Faiz NM, Bakar MZ, Allaudin ZN

PMID: 22458179

Autologous bone marrow, alone or as a composite marrow graft, has received much attention in various species. To assess the potential osteogenicity of autologous, extramedullary bone marrow implants in an avian model, 24 adult pigeons (Columba livia) were given intramuscular implantations of autologous marrow aspirated from the medial tibiotarsus. Birds were euthanatized at 1, 4, 6, 8, 10, and 12 weeks after surgery to evaluate whether ectopic bone had formed at the implant sites. Primary evaluations by in situ radiography and postmortem histologic examinations showed no evidence of bone formation. Further evaluation with histologic scores and histomorphometry revealed a significantly increased rate of angiogenesis at the implant sites by the sixth and tenth week postimplantation (P < .05). No significant differences between the treatment and control sites were present at any other endpoints. Results of this study show that, although autologous bone marrow lacks heterotopic osteogenic potentials in this avian model, it could still function as a useful adjunct to routine bone grafting techniques because of its unique capabilities to promote early angiogenesis.

Proximal Tibia Bone Graft: An alternative Donor Source especially for Foot and Ankle Procedures

Jia TY, Gurmeet S, Asni A, Ramanathan R

Malays Orthop J, 2015 Mar;9(1):14-17.
PMID: 28435589 MyJurnal DOI: 10.5704/MOJ.1503.016

Bone graft is essential in various orthopaedic procedures. Among the many donor sites for harvesting autologous bone graft, the iliac crest has been the most commonly used. However, for foot and ankle procedures the proximal tibia has gained popularity as an alternative donor site due to its anatomic proximity to the primary surgical site. In this article we evaluated the possible complications associated with harvesting proximal tibia bone graft. Our study showed the low incidence of morbidity in harvesting proximal tibia bone graft, thereby providing a good alternative donor for foot and ankle procedures.

Fulltext Alveolar Bone Grafting Without Closure Of Oronasal Fistula In Cleft And Palate Patient

Abdul Rahman, Z.A.

MyJurnal

The standard procedure for alveolar cleft closure in cleft lip and palate patients is by alveolar bone grafting (ABG) where the residual opening of oronasal fistula in the palate is also closed simultaneously. Occasionally there is a situation of soft tissue inadequacy and attempt to close the fistula at the same procedure as ABG may compromise the result of the bone graft itself. An unforeseen leakage at the closure may cause graft infection leading to failure. This article reports on a technique where alveolar bone grafting was done without closure of residual palatal fistula to provide adequate soft tissue coverage for the grafted bone. This may reduce the risk of leakage at the oral mucosal coverage of the graft . The residual palatal fistula will be closed at later stage by muco-palatal flap or tongue flap. We reported on a case of a failed ABG which was reconstructed using this technique. Various other techniques to ensure success of ABG were also discussed. Conclusion: The alveolar bone grafting without closure of oro-nasal fistula reduced the risk of failure of ABG in a wide alveolar cleft.

Fulltext Minimal guided bone regeneration procedure for immediate implant placement in the esthetic zone

Kumar NS, Sowmya N, Mehta DS, Kumar PS

Dent Res J (Isfahan), 2013 Jan;10(1):98-102.
PMID: 23878571 DOI: 10.4103/1735-3327.111808

The anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. With the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. Immediate implant placement has numerous advantages compared to the delayed procedure including superior esthetic and functional outcomes, maintenance of soft and hard tissue integrity and increased patient compliance. This case report exhibits immediate implant placement in the maxillary esthetic zone by combining a minimal invasive autogenous block bone graft harvest technique for ensuring successful osseointegration of the implant at the extraction site.

Ramdhan Ibrahim MA, Kamegaya M, Morita M, Saisu T, Kakizaki J, Oikawa Y

J Pediatr Orthop B, 2020 May;29(3):261-267.
PMID: 31688334 DOI: 10.1097/BPB.0000000000000681

Shelf acetabuloplasty continues to be effective in the prevention or delay of osteoarthritis in adolescent dysplastic hips. We aimed to evaluate the efficacy and to determine the correct level of the bone graft objectively. We retrospectively analyzed 16 hips underwent Shelf acetabuloplasty originated by Spitzy. The mean age at surgery was 15.3 years old with the mean caput index at 39.7%. The average follow-up was 11 years. The radiological evaluation was based on acetabular-head index (AHI) at preoperative and latest radiographs, acetabular-Shelf distance (ASD) and Shelf-head ratio at immediate postoperative and latest radiographs. The cutoff value for the ideal ASD was determined by receiver operating characteristic (ROC) and the Pearson correlation test used in statistical analysis to assess the relationship between ASD and Shelf graft resorption. Clinical evaluation was performed using Harris Hip Score (HHS) at the latest follow-up. The AHI was improved in all cases, from mean 56.9 to 91.0% (P bone resorption over time was at the level of 6 mm from the joint space. Level III - therapeutic study.

Fulltext Revision total hip arthroplasty using impaction bone grafting technique

Nisar A, Choon DS, Varaprasad M, Abbas AA

Med J Malaysia, 2006 Feb;61 Suppl A:100-2.
PMID: 17042242

A variety of reconstructive options exist for revision of both femoral and acetabular components in total hip replacement surgery. The use of impaction bone grafting with morsellised allograft has shown promising results in revision total hip arthroplasty. It works as a biologic reconstitution of bone stock defects and provides a solid construct with stable fixation. We present a case of bilateral revision total hip arthroplasty with poor bone stock where reconstructive surgery was done by using impaction bone grafting, mesh and C-stem implants.

Long-term effect on foot and ankle donor site following vascularized fibular graft resection in children

Sulaiman AR, Wan Z, Awang S, Che Ahmad A, Halim AS, Ahmad Mohd Zain R

J Pediatr Orthop B, 2015 Sep;24(5):450-5.
PMID: 26049965 DOI: 10.1097/BPB.0000000000000197

This study was carried out to evaluate the long-term effect on the donor side of the foot and ankle following vascularized fibular graft resection in children. Eight patients underwent resection of the fibula for the purpose of a vascularized fibular graft by a surgical team who practiced leaving at least 6 cm residual distal fibula. The age of these children at the time of surgery was between 3 and 12 years. They were reviewed between 3 and 12 years after surgery. Two patients who underwent resection of the middle shaft of the fibula at 3 and 5 years of age developed abnormal growth of the distal tibia, leading to ankle valgus. They were treated with growth modulation of the distal tibial physis and supramalleolar osteotomy with tibiofibular synostosis. Another patient who underwent the entire proximal fibula resection at the age of 6 years had developed hindfoot valgus because of weakness of the tibialis posterior muscle. He required talonavicular fusion and flexor hallucis to tibialis posterior muscle transfer. Patients operated at the age of older than 8 years neither had ankle nor hindfoot deformity. We concluded that resection of the middle shaft of the fibula for the purpose of a vascularized fibula graft, leaving a 6 cm distal fibular stump in children younger than 6 years old, may give rise to abnormal growth of the distal tibial physis, leading to valgus ankle. The entire proximal fibular resection for the similar purpose in a 6-year-old child may give rise to weakness of tibialis posterior and hindfoot valgus.

Platelet Rich Fibrin (PRF) is a natural autologous fibrin matrix and is an effective biomaterial product. The application of PRF in oral surgery is not limited to tissue regeneration, but it has been utilized in several minor and major oral surgical procedures. Numerous studies have proven that either alone or in combination with bone graft, PRF acts as bone and soft tissue regeneration and it is able to stimulate physiological wound healing. This case report will introduce the utilization of PRF combined with autogenous bone graft in restoring four walls dental socket defect due to post-surgical extraction complication and plan for implant placement in the future. It acts in the form of a resorbable membrane and stem cell connector to the bone. After 3 months post-surgery review, there was no signs of infection or tissue rejection and the harvested bone was still viable. The PRF is comparable to commercially available membrane in the market, where clinical results can be predicted and possibility of reduction in post-surgical complications is achieved. This is due to 1) its compatibility with bone graft materials notably autogenous type, 2) induced neovascularisation and 3) reduction in inflammatory reaction. Our team is confident that the result of PRF at the edentulous region for rehabilitation purposes is beneficial and cost-effective to our patients.

Role of Synthetic Hydroxyapatite-In Socket Preservation: A Systematic Review and Meta-analysis

Kattimani VS, Prathigudupu RS, Jairaj A, Khader MA, Rajeev K, Khader AA

J Contemp Dent Pract, 2019 Aug 01;20(8):987-993.
PMID: 31797859

Since a long time, the preservation of the socket is emphasized for various reasons. Many studies have suggested the ridge preservation through socket grafting using various bone graft substitute materials (GSMs). But none of the studies suggested the material of choice for the grafting. So, the systematic review was planned to analyze the outcomes of synthetic hydroxyapatite (SHA) graft material for socket preservation. The review was aimed to determine the existing evidence for the use of SHA GSM for grafting and its usefulness.
MATERIALS AND METHODS: The literature search was performed for the studies published in the English language independently by all four authors (search team) in the Medline database through the PubMed search engine for the past 5 years. The study involved predetermined inclusion and exclusion criteria for the search. The final lists of clinical trials were analyzed to determine the existing evidence and suggested the mechanism of action.
REVIEW RESULTS: The search resulted in 117 titles. After application of inclusion and exclusion criteria, a total of seven studies were found eligible for this systematic review. Out of seven, two studies were found eligible for meta-analysis whereas remaining included for the systematic review.
CONCLUSION: The meta-analysis favors socket grafting compared to control in terms of preservation of existing bone height and width. The SHA grafting showed successful bone regeneration with less connective tissue component. The histomorphometric evaluation showed a good bone regeneration associated with SHA than xenograft. Within the limitations of this meta-analysis, the synthetic GSM can be used for socket grafting.
CLINICAL SIGNIFICANCE: In the wake of increasing graft materials in the market and different origin raw material sources for the preparation of graft materials, clinicians are in dilemma for selection and its use. The success of grafting depends on the selection of appropriate material with a suitable calcium/phosphate (Ca/P) ratio. The review provided available evidence for the use of SHA.
