Aims

Reconstruction of soft tissues and preservation of the extensor mechanism integrity provide a major challenge following resection of the proximal tibia tumours. We propose a novel surgical technique for neopatellar ligament reconstruction using hamstring tendon in proximal tibia tumour cases. This study details the surgical technique, early clinical and radiological outcomes, and the potential long-term benefits of this innovative reconstructive approach following proximal tibia megaprosthesis implantation.

Aims

Assessment of bone health is a multifaceted clinical process, incorporating biochemical and diagnostic tests that should be accurate and reproducible. Dual-energy X-ray absorptiometry (DXA) is the reference standard for evaluation of bone mineral density, but has known limitations. Alternatives include quantitative CT (q-CT), MRI, and peripheral quantitative ultrasound (QUS). Radiofrequency echographic multispectrometry (REMS) is a new generation of ultrasound technology used for the assessment of bone mineral density (BMD) at axial sites that is as accurate as quality-assured DXA scans. It also provides an assessment of the quality of bone architecture. This will be of direct value and significance to orthopaedic surgeons when planning surgical procedures, including fracture fixation and surgery of the hip and spine, since BMD alone is a poor predictor of fracture risk.

Aims

To evaluate the diagnostic characteristics and reliability of radiological methods used to assess scaphoid fracture union through a systematic review and meta-analysis.

Aims

Nonunion occurs when a fracture fails to heal permanently, often necessitating surgical intervention to stimulate the bone healing response. Current animal models of long-bone nonunion do not adequately replicate human pathological conditions. This study was intended as a preliminary investigation of a novel rat nonunion model using a two-stage surgical intervention, and to evaluate the efficacy of a selective prostaglandin E2 receptor 4 agonist (AKDS001) as a novel nonunion therapeutic agent compared with existing treatments.

The last five years have seen notable advancements in foot and ankle surgery as a result of technical innovations and more consistent reporting of results. Much progress has been made in improving patient-reported outcome measures, in the development of basic research in this area, and in the development of personalized approaches which optimize outcomes for specific groups of patients. This review focuses on five main areas of development within foot and ankle surgery: ankle arthroplasty, osteomyelitis and the diabetic foot, sports injuries, minimally invasive surgery, and orthobiologics. The aim of this annotation is to discuss the progress made in these fields during recent years and propose avenues for further development.

The use of arthroscopy of the hand and wrist has recently increased sharply in the elective setting and this, not surprisingly, has been followed by an increasing use in the trauma setting. Advocates for the use of arthroscopy in these patients cite the improved assessment of the displacement and reduction of fractures and the early diagnosis of associated injuries, while others temper this with concerns about increased operating time and possible complications. The data relating to patient-reported benefits and costs are limited. The aim of this review was to discuss the current available literature for the use of arthroscopy in the management of injuries of the hand and wrist.

Aims

Revision hip arthroplasty for femoral stem loosening remains challenging due to significant bone loss and deformities requiring specialized revision stems. The aim of this study was to evaluate the clinical and radiological outcomes, and survival, of a consecutive series of femoral revisions performed using a primary cementless stem with tapered geometry and rectangular cross-section at medium-term follow-up.

Background. Freibergs infraction is osteonecrosis of lesser metatarsal heads, most commonly affecting adolescent females. They usually present with pain and swelling of the forefoot. Surgical options include open debridement, cheilectomy, micro fracture osteotomy and excision arthroplasty. The aim of the study is to present the results of our surgical method based on the principle of neo-angiogenesis, neo-osteogenesis and neo-chondrogenesis with bone grafting and AMIC membrane application for Freiberg's disease of lesser metatarsals. Methods. A prospective analysis of twelve patients who had Freiberg's infraction of the lesser toe metatarsals treated with open debridement, microfracture, bone grafting and application of AMIC membrane was carried out. The patients were followed up to seven years and the outcome measures were scored using Smillie's classification, radiological findings and the Manchester-Oxford Foot Questionnaire (MOxFQ). Results. There were 9 (75%) female and 3(25%) male patients. The mean age was 42.7 years (range- 19 to 60). The mean follow-up time was 6.6 years. The most common site was second metatarsal, ten (83%) followed by third metatarsal, two (17%). According to Smillie's classification three lesions were labelled as Stage 3 and ten as Stage 4. There were no postoperative infections. None of the patients needed any further surgical intervention. The mean base line MOxFQ was 43.75 (SD- 43.75±12.40) which improved to 7.19(SD-7.18±4.63) the mean baseline EQ-5D improved from 7.85 (SD-7.85±5.08) to1.39(SD-1.39±0.75) at the final follow up. 80 % of the patients had complete remodelling of the head of metatarsal at the final follow up radiology. Conclusions. Open debridement of the Freiberg\'s disease combined with microfracture of the defect, bone grafting and application of AMIC membrane gives good long term functional outcomes

The aim was to demonstrate that Supramalleolar osteotomy is a valuable treatment method in eccentric ankle arthritis in young and middle aged since it is an under-utilised procedure. We retrospectively analysed the outcome of it performed over 12 year period. We also compared the results of recently introduced computer-assisted PSI Integrated custom-made implants with standard implants. Data was analysed from 48 patients over a period of 12 years of which 40 were by standard implant and 8 by computer assisted custom implant. 31 varus, 18 valgus deformity. The mean age was 57 (26–79 y/o), male:female ratio was 27:19. Mean follow-up was 15.25 months for standard implants; For the computer-assisted procedures the follow up range is 24 to 2 months. TAS, TTS and TT angels were measured pre and post-operatively. Fixation using a plate with/without bone graft or custom-made implant was performed by a single surgeon. MOXFQ and AOFAS questionnaires were completed pre and post-operatively. All followed similar rehabilitation programme. Average radiological healing time was 24.3 weeks. MOXFQ score improved from 55.17 to 25.11 and AOFAS from 20.16 to 56.21. Complications were 2 non-unions, 1 delayed union, 1 stress fracture. 8 patients require fusion/replacement between 3–5 years. The PSI Integrated computer-assisted technique gave improved accuracy than standard freehand method with better scores and a smoother approach for the surgeon. Early results with this technique are encouraging as we were able achieve 3 dimentional correction compared to the 2 dimentional correction achieved by the freehand method. Our results are comparable to similar studies. Being a joint preserving technique, Supra Malleolar Osteotomy should be considered either as an interim or definitive procedure especially with the development of computer assisted technologies which makes the technique easier to reproduce

Introduction. The treatment of critical-sized bone defects in foot and ankle surgery remains challenging. Traditional methods, such as bone transport, bulk allograft, vascularized bone graft, and Masquelet procedures carry risks including multiple surgeries, donor site morbidity, infection, and non-union. Recently, custom 3D-printed implants have emerged, offering improved anatomical compatibility, eliminating the need for tissue harvesting, and often requiring only a single operation. This study aims to present the largest UK series of custom 3D-printed implants in foot and ankle surgery. Methods. A retrospective multicentre collaborative study was conducted in 10 NHS Trusts. Demographic, surgical and radiographic variables were recorded including: age; sex; side; type of operation; complications; and postop imaging at 6 weeks, 3 months, 6 months and 12 months. Baseline characteristics were described for demographic variables. Categorical variables were expressed as frequencies and percentages. Results. Data was collected on a total of 34 patients. The mean age of patients was 54 years (range 29 to 83). 68% of patients were men. Avascular necrosis was the most common indication for surgery (35%) followed by trauma (21%), total ankle replacement failure (21%), infection (12%), Charcot arthropathy (6%) and AVN and infection (3%). The most common operation performed was a fusion augmented with a truss (44%) and 91% of patients had a combination of regional and general anaesthetic. All patients had an ASA grade of less than 4. Of the patients that had follow-up imaging, the implants were reported intact by 94% at 6 weeks, 78% at 3 months, 68% at 6 months and 67% at 12 months. Discussion. This is the largest case series of custom-made foot and ankle implants in the UK to date. The clinical and radiographic outcomes at one year Follow-up are satisfactory. Further work is required to assess long term implant survivorship

Aims. Autologous bone graft (ABG) is considered the ‘gold standard’ among graft materials for bone regeneration. However, complications including limited availability, donor site morbidity, and deterioration of regenerative capacity over time have been reported. P-15 is a synthetic peptide that mimics the cell binding domain of Type-I collagen. This peptide stimulates new bone formation by enhancing osteogenic cell attachment, proliferation, and differentiation. The objective of this study was to conduct a systematic literature review to determine the clinical efficacy and safety of P-15 peptide in bone regeneration throughout the skeletal system. Methods. PubMed, Embase, Web of Science, and Cochrane Library were searched for relevant articles on 13 May 2023. The systematic review was reported according to the PRISMA guidelines. Two reviewers independently screened and assessed the identified articles. Quality assessment was conducted using the methodological index for non-randomized studies and the risk of bias assessment tool for randomized controlled trials. Results. After screening, 28 articles were included and grouped by surgical indication, e.g. maxillofacial procedures (n = 18), spine (n = 9), and trauma (n = 1). Published results showed that P-15 peptide was effective in spinal fusion (n = 7) and maxillofacial (n = 11), with very few clinically relevant adverse events related to P-15 peptide. Conclusion. This systematic literature review concluded that moderate- (risk of bias, some concern: 50%) to high-quality (risk of bias, low: 46%) clinical evidence exists showing equivalent safety and efficacy in bone regeneration using a P-15 peptide enhanced bone graft substitute compared to ABG. P-15 peptide is safe and effective, resulting in rapid bone formation with a low probability of minor complications. Cite this article: Bone Joint Res 2025;14(2):77–92

Addressing bone defects is a complex medical challenge that involves dealing with various skeletal conditions, including fractures, osteoporosis (OP), bone tumours, and bone infection defects. Despite the availability of multiple conventional treatments for these skeletal conditions, numerous limitations and unresolved issues persist. As a solution, advancements in biomedical materials have recently resulted in novel therapeutic concepts. As an emerging biomaterial for bone defect treatment, graphene oxide (GO) in particular has gained substantial attention from researchers due to its potential applications and prospects. In other words, GO scaffolds have demonstrated remarkable potential for bone defect treatment. Furthermore, GO-loaded biomaterials can promote osteoblast adhesion, proliferation, and differentiation while stimulating bone matrix deposition and formation. Given their favourable biocompatibility and osteoinductive capabilities, these materials offer a novel therapeutic avenue for bone tissue regeneration and repair. This comprehensive review systematically outlines GO scaffolds’ diverse roles and potential applications in bone defect treatment.

Aims

The aim of the LightFix Trial was to evaluate the clinical outcomes for one year after the treatment of impending and completed pathological fractures of the humerus using the IlluminOss System (IS), and to analyze the performance of this device.

Aim. This retrospective study evaluated the outcome of treatment for unhealed fracture-related infections (FRI). Methods. We identified a consecutive, single-centre cohort of patients having treatment for an FRI Consensus confirmed FRI. All fractures were unhealed at the time of treatment. Patients were followed up for at least one year. Successful outcome was a healed fracture without recurrent infection. Lack of union, persistent infection and/or unplanned reoperation defined failure. Results. Demographics: 183 patients (184 FRIs) with mean age 52.1 years (range 17-96) were treated and followed up for a mean of 2.8 years (range 1-9.4). Mean duration of FRI was 1.1 years with 65 (35.5 %) presenting within 6 months of injury. 118 patients had established infected non-union. FRI was most frequent in the tibia (74), femur (48) and humerus (24). 171 patients were BACH Complex. 75.5% of FRIs were culture positive, with Staph. aureus being the most frequent organism. Polymicrobial infection and Gram negative cultures were common (25.5% and 33.6%). Treatment: 98.3% of surgeries were performed in one stage with just 3 planned 2-stage procedures (2 endoprosthetic replacements and 1 free fibular flap). No bone graft was used in any surgery and all wounds were closed at first operation. 48 cases (26%) required flap coverage (29 free flaps and 19 local flaps). Local antibiotics were used in 124 cases (67.4%) of primary surgeries. All patients had sampling, debridement, systemic antibiotics and wound closure. 40 (21.7%) had DAIR, 31 (16.8%) had new internal fixation and 105 (57.1%) had external fixation (including 79 Ilizarov fixators). Outcomes: After primary surgery, 84.6% of all patients were infection-free and 77.2% had united. After further surgery, 98.8% were infection-free and 98.1% had united. External fixation techniques achieved infection eradication in 89.1% compared to 71.7% with any internal fixation (p=0.005). Primary internal fixation achieved union in 81.7% compared to 74.3% with external fixation (p=0.27). Secondary surgery after external fixation was mainly docking site fixation. Conclusion. Unhealed FRIs present a difficult challenge for treatment. This large series demonstrated that single-stage treatment, without bone grafting, gave acceptable results with few reoperations. Primary external fixation gave more certainty of infection eradication but required more reoperations to secure union. However, this difference in reoperation was not statistically significant. We strongly advocate managing these patients with a multidisciplinary team which can treat all aspects of the condition
