- Acetabular Reconstruction
-
- This study assessed long-term outcomes of complex acetabular revisions, focusing on cases where at least 50% contact between allograft bone and the prosthetic cup was achieved. Results suggest that massive allograft reconstruction of the acetabulum can provide immediate and long-term stability for the prosthetic cup, and effectively restore bone stock.
- This study evaluated the outcomes of acetabular reconstruction using a KT plate with either bulk or morselised femoral head allografts. The researchers concluded that bulk femoral head allografts are necessary for achieving mechanically stable reconstruction for large acetabular bone defects.
- This study investigated the long-term outcomes of acetabular reconstruction using autogenous and allografts from the femoral head in complex total hip arthroplasty, and found these grafts performed well for the initial five to ten years but faced increased failure rates by an average of 16.5 years.
- Osteonecrosis of the Femoral Head (ONFH)
- Periprosthetic Fracture
-
- The study discusses cortical onlay strut allografting as an increasingly preferred method for treating periprosthetic femoral fractures around stable implants, given their ability to provide mechanical stability, enhance fracture healing, and potentially increase bone stock. Because of their similar elasticity modulus to host bone, these bone struts cause less stress shielding than other, more rigid, internal fixation methods and can be used alongside other treatment modalities such as plate fixation or with a long-stem prosthesis revision.
- The study investigates the treatment of periprosthetic femoral fractures around stable implants using cortical onlay strut allografts alone or in conjunction with a plate, revealing a high rate of fracture union, satisfactory alignment, and increased femoral bone stock. The authors conclude that cortical strut grafts should be routinely employed to augment fixation and healing of a periprosthetic femoral fracture given their dual mechanical and biological function.
- The study compares two surgical treatments for femoral periprosthetic fractures: plate fixation alone and plate fixation with a strut allograft. Findings indicate that patients treated with plate fixation and a strut allograft experienced better outcomes, including lower surgical failure rates and enhanced biological healing. Strut allograft augmentation provides additional mechanical stability and contributes to fracture healing via osteoconduction.
- The article reviews the use of cortical onlay strut allografts in periprosthetic femoral fractures. Despite the effectiveness of strut allografts in providing structural support and increasing bone stock, concerns such as regarding soft tissue damage, potential infection make their routine use controversial, hence the need for further comparative studies to determinethe most effective treatment for PFF.
- Pelvic Osteotomy
-
- This study discusses the challenges of treating severe hip dysplasia with hip arthroscopy. While periacetabular osteotomy is the conventional treatment, its invasive nature and lengthy recovery can deter patients. The authors propose a minimally invasive endoscopic technique involving allograft iliac bone grafting, which could reduce donor-side morbidity and make the procedure less invasive.
- This retrospective study evaluated the use of allograft bone wedges in Pemberton osteotomies for the treatment of acetabular dysplasia, finding substantial improvement in both acetabular and lateral migration indices post-surgery. The technique provided immediate graft stability and often eliminated the need for postoperative spica casting, thereby accelerating the rehabilitation process.
Foot & Ankle
- Tibiotalocalcaneal Arthrodesis (TTC)
-
- This study presents two cases where Tibiotalocalcaneal (TTC) arthrodesis, using a bulk femoral head allograft and a novel pseudoelastic intramedullary nail, successfully salvaged failed total
ankle replacements. These cases provide initial evidence that this approach is an effective treatment for failed total ankle replacements. - This study reviewed 24 Tibiotalocalcaneal (TTC) arthrodesis procedures with femoral head allografts. It suggested that the use of femoral head allograft with TTC arthrodesis resulted in improved functional scores, sustained radiographic outcomes, and complete radiographic union in 63% of patients and 75% of all joints, suggesting its potential as a beneficial treatment for complex hindfoot osseous deficits.

- Hallux Valgus Osteotomy/Lapidus Arthrodesis
-
- This study found no significant difference in union rates between Lapidus arthrodesis cases that used an allograft bone wedge (90%) and those that did not (97%), but there was a
significant difference in union rates when comparing the use of two crossed compression screws (85%) to a medial locking plate with a single transarticular screw (98%). The research
highlights the importance of robust fixation when using an allograft bone wedge, and demonstrates that it offers a valuable option in cases requiring extensive bony resection due to severe deformity, or where there’s a considerable length discrepancy between the first and second metatarsal. - This study examined the use of an allograft bone wedge in Lapidus procedures, finding that the use of an allograft bone wedge, particularly with a medial locking plate and intra-articular
compression screw, can aid in decisions regarding bony resection, potentially reduce the risk of metatarsalgia due to shortening, and allow for more significant corrections while maintaining satisfactory union rates.

- Cotton Osteotomy
-
- The study presents a retrospective review of Cotton osteotomy as an adjunctive procedure in flatfoot reconstructive surgery, demonstrating its effectiveness in correcting forefoot varus deformity. A tricortical wedge cut from an iliac crest was press-fit into an osteotomy created in the medial cuneiform, successfully serving as a structural support and promoting proper alignment.
- This study presents the case of a successful Cotton osteotomy on an adolescent patient,emphasizing the use of allografts and an innovative nerve-centric incision design. The use of allografts in the Cotton osteotomy has been shown to achieve similar union rates to autografts, demonstrating their efficacy in the procedure, and their suitability is further exemplified by the absence of complications such as nonunion, graft failure, infection, or reoperation in published reports.
- Evans Osteotomy/Lateral Column Lengthening (LCL)
-
- This study compared the outcomes of using iliac tricortical autograft versus allograft supplemented with platelet rich plasma (PRP) in lateral column lengthening procedures. Iliac tricortical allograft supplemented with PRP demonstrated superior outcomes compared to iliac tricortical autograft.
- This study evaluated the effectiveness of using autograft versus allograft bone in lateral column lengthening (LCL) procedures. Over a three-year period, the research analyzed 126 LCLs performed on 120 patients and found that failure rates were not significantly different between autograft and allograft methods.
- The study reviewed medical records of 51 patients who underwent anterior calcaneal osteotomy (ACO) with allogenic bone graft for flatfoot deformity, with an objective to understand the outcomes associated with the use of allograft. The findings suggest that ACO with allogenic bone graft is a viable alternative to autograft for the treatment of flexible flatfoot in both adolescent and adult patients.
Spine
- Anterior Cervical Discectomy and Fusion (ACDF)
-
- Seminal paper by Dr. Arthur L. Cloward that introduced the ACDF procedure and the use of bone dowels.
- In a prospective randomized study, the authors found that glycerol-preserved Cloward dowels demonstrated fusion outcomes and subsidence values comparable to freeze-dried Cloward dowels in Anterior Cervical Discectomy and Fusion (ACDF) procedures.
- Spinal Fusion
-
- Allografts and cage devices, frequently used in spinal reconstruction, reduce donor site morbidity and offer diverse graft options, with cylindrical cages gaining popularity due to
improving compatibility with host vertebral bone. - This retrospective study analyzed 32 patients who underwent single-level anterior lumbar fusion with femoral strut allograft, measuring outcomes like interspace distraction, graft subsidence, and arthrodesis success. The results showed solid or functional arthrodesis in most of the patients.
- This study compared the mechanical properties of allogeneic iliac crest wedges in spinal fusion procedures, categorized into three subgroups: frozen-thawed, freeze-dried, and rehydrated. The findings suggest that rehydrated or frozen-thawed iliac crest wedges demonstrate superior load-bearing capacity, compressive strength, and deformability.

- Anterior Spinal Column Reconstruction
-
- This study analyzed the outcomes of anterior spinal column reconstruction using structuralfemoral shaft allografts in osteoporotic patients, finding that the procedure significantly improved patients’ ambulatory status and reduced back pain, while effectively correcting kyphotic deformity with minimal graft subsidence.
- This study explores the use of bone allografts in spinal surgery, discussing their success in various applications. It concludes that successful use of allograft bone in the spine depends on factors such as the type of allograft used, its anatomic site of fusion, and the patient’s age.
