Robotic-assisted hip and knee arthroplasty represents cutting-edge advancements in orthopedic surgery, harnessing robotic technology to enhance precision, improve clinical outcomes, and facilitate intra-operative procedures. In these robotic-assisted surgeries, the robotic systems assist surgeons in planning and executing joint replacement surgeries, thereby facilitating personalized implant positioning and optimizing the fit and alignment of hip and knee implants. Despite the increasing attention garnered by robotic-assisted hip and knee arthroplasty in recent years, a comprehensive bibliometric analysis using the Scopus database has yet to be conducted. This bibliometric analysis reviews the Scopus database from 1961 until 2022 to investigate the literature on the field of robotic-assisted hip and knee arthroplasty. A total of 577 articles that satisfied the selection criteria were included in this review. The majority of the articles focus more on total knee replacement, compared to total hip replacement and unicompartmental knee arthroplasty. The overwhelming majority of the articles were authored by researchers and clinicians from the United States of America (USA) and the United Kingdom (UK). Similarly, most of the articles with the highest number of citations were authored by researchers and clinicians from these regions. This comprehensive bibliometric analysis using Scopus in the domain of robotic-assisted hip and knee replacement has the potential to act as a roadmap for researchers, clinicians, and policymakers, facilitating informed decision-making, promoting collaborative initiatives, and guiding the development of future studies to further advance the field of robotic-assisted hip and knee arthroplasty.

Ascorbic acid (vitamin C) is an essential micronutrient that the human's body cannot synthesize endogenously. Scurvy, a disease of ascorbic acid deficiency, can manifest in a myriad of presentations. Due to its rarity in the modern world, scurvy is considered as a disease of the past. We present a paediatric case of scurvy with musculoskeletal manifestations as a result of picky eating behavior. We report a previously healthy nine-year-old boy who presented with unexplained progressive bilateral lower limb generalized weakness and pain for two months. All initial biochemical and radiological investigations were unremarkable. Upon further history taking, he had severe picky eating behavior which raised the suspicion of scurvy. The diagnosis was confirmed with a serum ascorbic acid test. After ascorbic acid supplementation, his symptoms resolved immediately. Further food behavioral modification counselling to his family members helped to change his diet in a lasting way. As a result, he had no recurrence of symptoms. This case highlights the importance of having a high index of suspicion for an uncommon disease and emphasizes the need for a detailed dietary history upon patient's presentation.

Kow RY, Yuen JC, Ahmad Alwi AA, Abas MF, Low CL

JBJS Case Connect, 2019 6 25;9(2):e0163.
PMID: 31233428 DOI: 10.2106/JBJS.CC.18.00163

CASE: A 17-year-old male sustained an open fracture of the right medial malleolus (MM) with significant bone and soft tissue loss following a motor-vehicle accident. Following serial wound debridement, his ankle was effectively reconstructed with MM antiglide plate stabilization, iliac autogenous bone graft, and a free radial forearm soft tissue flap.
CONCLUSIONS: Open MM fracture with bone and soft tissue loss is rare. It is feasible to treat this injury with a novel surgical reconstruction technique involving autogenous bicortical iliac bone graft and radial forearm free flap.

The human foot serves as an important part to support
the body weight and accounts for the majority of our
movements. A mangled limb involves injury to at least
three out of four systems, namely the soft tissues, nerves,
blood supply and bone. While amputation is indicated in
some cases of mangled limb, with proper planning, limb
salvaging surgical management is also a viable option.
Special consideration to the skeletal stabilization, control
of infection, vascular status and soft tissue coverage is
paramount to the success of limb salvaging surgery. We
present a case of mangled limb which was successfully
treated with limb salvaging surgical management. Initial
debridement, Kirschner wires insertion and cross ankle
external fixation were used for skeletal stabilization. An
antibiotic spacer was inserted for local antibiotic and to
maintain the length left due to the loss of medial and
intermediate cuneiform bones. The anterior tibialis
artery and its venae comitantes were utilized for free
vascularized fibular graft to provide bony reconstruction
as well as soft tissue coverage for the mangled foot.
Fulltext Telescoping Allograft Prosthetic Composite (APC) Reconstruction of the Femur Following Revision Arthroplasty for Neglected Developmental Dysplasia of the Hip (DDH)

Although uncommon, neglected developmental dysplasia of the hip (DDH) poses a technically demanding problem for treating surgeons. Due to the congenital malformation of the native hip joint and distortion of the surrounding soft tissue, addressing limb-length discrepancy is intricate. Despite detailed planning and meticulous soft tissue handling, complications can be difficult to avoid in these patients even under experienced hands. In this case report, we present a 73-year-old lady with neglected DDH who had undergone initial total hip arthroplasty and subsequent revision surgery that failed due to aseptic loosening. Due to limited length in the distal femur, we used a telescoping allograft prosthetic composite (APC) to provide adequate length to the native distal femur during revision with proximal femur fixation. This technique can help avoid the need for total femur replacement (TFR) surgery, which is more invasive and may require tibia replacement.
Fulltext The Creation of Articulating Cement Spacer Using Custom-Fabricated Silicone Mold for the Treatment of Periprosthetic Joint Infection: Two Case Reports

Joint replacement surgeries have been performed to treat joint arthropathies with excellent outcomes. As the number of joint replacement surgeries surges, the incidence of periprosthetic joint infection (PJI) has also increased. Currently, two-stage revision surgery is the gold standard in the treatment of periprosthetic joint infection. Two-stage revision surgery involves joint washout, the removal of the primary implant, the insertion of a cement spacer, and subsequently the reimplantation of prosthesis after the infection has been eliminated. Custom-made articulating cement spacer has been used with success to improve the patient's ambulatory status and quality of life. Nevertheless, custom-made articulating cement spacer or commercialized cement mold is generally costly. By the modification of previous authors' techniques, we manage to fabricate reusable silicone molds, which can be used to create articulating cement spacers for both hip and knee joints. We share two case reports to illustrate how these fabricated silicone molds can be a cost-effective technique to create articulating cement spacers to manage periprosthetic joint infection in both hip and knee joints. Surgeons in resource-deprived countries can utilize this technique to create articulating cement spacers with minimal cost, but they need to discuss with their patients and check with the local regulatory board on the feasibility of this technique to create cement spacer that will be used in a patient.

Background: The Michigan Hand Outcomes Questionnaire (MHQ), a self-reported questionnaire for patients with hand disorders, has been widely used globally. It has been cross-culturally adapted into different languages across all continents. Aims of this study were to translate the MHQ into Malay language and to evaluate its reliability and validity compared with Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire in a Malay-speaking population. Methods: The MHQ was cross-culturally adapted into a Malay version based on the guidelines. A pre-testing involving thirty patients with hand disorders was performed to assess whether it was comprehensible to the target population. One hundred patients with hand disorders were recruited in this study to answer the MHQ and DASH questionnaires. The MHQ was tested twice with an interval of two weeks in between. Statistical analysis was performed to assess the reproducibility and internal consistency via the test-retest method and Cronbach's alpha calculation, respectively. The association between MHQ and DASH questionnaire was assessed with Spearman's correlation calculation. Results: In the pre-testing, twenty-six patients (86.7%) understood all the questions in the Malay version of MHQ. The test-retest analysis showed a good reliability across the duration of two weeks with the intraclass correlation coefficient of all subscales ranging from 0.925 to 0.984. Cronbach's alpha values of the Malay version MHQ ranged from 0.82 to 0.97, indicating a good internal consistency. Spearman's correlation factor of the MHQ in comparison with DASH showed a fair to moderately strong correlation with the values ranging from 0.513 to 0.757. Conclusions: The Malay version of MHQ was successfully translated and culturally-adapted with excellent reliability (reproducibility and internal consistency) and good construct validity.
Fulltext The Role of Medial Plantar Artery Flap in Heel Pad Reconstruction: A Report of Two Cases

The heel and sole possess unique anatomical characteristics that serve a weight-bearing and shock-absorbing function. The heel is particularly vital, as any defects in this area can lead to gait instability. Reconstructing a heel defect presents challenges, as the donor flap must be durable enough to withstand high force loads while also providing protective sensation. Recently, the medial plantar artery flap has been successfully employed for the reconstruction of defective heel pads. This flap offers glabrous skin capable of weight transmission and intact protective sensation. In this report, we present two cases of heel pad loss secondary to chronic diabetic complications and trauma, respectively, which were treated with medial plantar artery flap reconstruction. Both cases were successfully treated, and they showed a good functional outcome.

The occurrence of atlantoaxial rotatory subluxation is fairly uncommon; however, it is
more common to be encountered in the paediatric population, typically seen after a
retropharyngeal inflammation or after a minor trauma. Ligamentous laxity, shallower
and more horizontally oriented facet joints especially at the C1-2 joint making them
prone to have atlantoaxial subluxation or dislocation. (Copied from article).
