  • International Consensus Statement on the Management of Glenohumeral Arthritis in Patients ≤ 50 Years Old. [Journal Article]
    J Shoulder Elbow Surg. 2023 Jan 31 [Online ahead of print]Colasanti CA, Lin CC, … Zuckerman JD
  • CONCLUSIONS: The optimal treatment of glenohumeral arthritis in patients ≤ 50 years of age remains controversial, and there are many treatment options to consider when responding to the variety of clinical presentations and anatomic pathologies. While physicians and patients engage in the shared decision-making process regarding the final choice for management, this consensus statement serves as a basis for discussion amongst colleagues and between patients and surgeons though it clearly demonstrates that the topic must be further investigated prospectively and with large cohorts.
  • Modernizing Our Understanding of Total Hip Arthroplasty in the Pediatric and Young Adult Patient: A Single-center Experience. [Journal Article]
    J Pediatr Orthop. 2023 Jan 19 [Online ahead of print]Whitmarsh-Brown MA, Christ AB, … Goldstein RY
  • CONCLUSIONS: Modern PYA THA is dissimilar in indications and surgical techniques to historic cohorts, and conclusions from prior studies should not be generalized to modern practice. In our practice, PYA patients most commonly carry a diagnosis of AVN, and THA can be performed with modern cementless fixation with large cup and head sizes and ceramic-on-cross-linked polyethylene bearings utilizing any approach. Further study is required to better characterize middle-term and long-term results and patient-reported outcomes.
  • Low complexity symmetric-coded based sphere decoding for low-rate polar codes. [Journal Article]
    Sci Rep. 2023 Jan 21; 13(1):1191.Liu Y, Chen H, … Li X
  • The sphere decoding (SD) algorithm can provide (sub)optimal solutions with reduced computational complexity of maximum likelihood (ML) detection for multi-input multi-output (MIMO) communication systems. In this paper, we propose a novel low complexity symmetric-coded based SD algorithm for short polar codes with low rate. At the encoding stage, the first N/2 sub-channels transmit the frozen bits…
  • Complications after talus fractures: A trauma centre experience. [Journal Article]
    Injury. 2022 Dec 15 [Online ahead of print]Pradhan A, Najefi A, … Jeyaseelan L
  • CONCLUSIONS: Our study found that talar body fractures are more common than previously reported; however, talar neck fractures cause the highest rates of AVN and post-traumatic arthritis. Open fractures also carry a greater risk of complications. This information is useful during consenting and preoperatively when planning these cases to ensure adverse outcomes may be anticipated.
  • Management of Scaphoid Nonunion (SNU) With Ilizarov Ring Fixator Using Two Olive Wire Compression Without Bone Grafting: A Case Series. [Journal Article]
    Cureus. 2022 Nov; 14(11):e31646.Bari M, Konchada S, … Dhingra K
  • CONCLUSIONS: With our technique of Ilizarov fixation and compression with two cross olive wires, SNU can be treated safely even without opening the non-union site and even without bone grafting. Since we excluded SNU patients with humpback deformity, carpal instability, carpal collapse, or avascular necrosis (AVN), our results might not be directly comparable to those of other SNU series in the literature. These would have predisposed to a poor outcome. Since we did not assign the patients at random, it is challenging to compare the Ilizarov technique to other widely used SNU treatments and determine whether it is more effective. However, the study's results are encouraging and show that the Ilizarov method using two olive wires for compression.
  • Ex vivo study of detergent-assisted intraosseous bone wash treatment of osteonecrosis. [Journal Article]
    J Orthop Res. 2022 Dec 01 [Online ahead of print]Andre G, Boschetto F, … Ma C
  • Avascular necrosis (AVN) involves ischemic cell death of the bone. AVN leaves an abundance of necrotic lipids and debris in the bone marrow, which instigates inflammatory bone repair. Consequently, the necrotic bone microenvironment stimulates excessive bone resorption, leading to joint deformities and osteoarthritis. Here, we performed a detergent-assisted bone wash using poloxamer 407 (P407) to…
  • Diagnosis and Treatment of Avascular Necrosis of the Humeral Head: Current Concepts. [Journal Article]
    J ISAKOS. 2022 Nov 23 [Online ahead of print]Lee WQ, Lie MH, Lie TTD
  • Avascular necrosis (AVN) of the humeral head is an uncommon clinical entity which can result in significant morbidity for patients. Compared to femoral head AVN, the volume of literature concerning humeral head AVN is a distant second. This could be due to the relatively rarity of the condition and poorly understood nature. Despite being first described decades ago, the underlying pathophysiology…
  • Does Diabetes Mellitus Increase the Risk of Avascular Osteonecrosis? A Systematic Review and Meta-Analysis. [Review]
    Int J Environ Res Public Health. 2022 11 18; 19(22)Konarski W, Poboży T, … Krakowiak J
  • Avascular osteonecrosis (AVN) is caused by the disrupted blood supply to the bone. Most AVN cases occur in the femoral head, but other sites might be affected as well, including the jaw or distal bones of the extremities. Previous studies suggested that diabetes could increase the risk of AVN of the jaw, but the relationship between diabetes and AVN in other bone sites is unclear. This systematic…
