A positive ulnar fovea sign is usually considered to be specific for foveal disruption of the distal radioulnar ligaments. A retrospective review was done of 73 patients with a positive ulnar fovea sign. Only 21 patients had a foveal tear on arthroscopic examination. Level of evidence: IV., Competing Interests: Declaration of conflicting interestsThe authors declared that there are no potential conflicts of interest with respect to the research, authorship, and publication of this article.

Introduction: Hand tumours are frequently encountered in clinical practice. However, large-scale epidemiological data of soft tissue tumours in the hand are infrequently published. Epidemiological data provide diagnostic cues to guide the workup and management of hand tumours. Assessing significant independent demographic factors and tumour characteristics associated with hand tumours is essential in health care., Methods: A retrospective review of patients who underwent excision of hand tumours in Singapore General Hospital between 2004 and 2015 was conducted. The data collected included age, gender, ethnicity, histological diagnosis, malignancy and location of tumour. Generalised linear latent and mixed models (GLLAMM) analyses were performed., Results: A total of 4476 tumours were identified from 4226 patients with a mean age of 51.3 (range 8-101) years and male to female ratio of 1 to 1.15. Most patients were Chinese (75%), followed by Malay (9%), Indian (8%) and others (8%). The most common hand tumours excised were ganglions (43%) (majority in the wrist), followed by giant cell tumours (9%) (commonly in the digits). Most soft tissue tumours were benign (97%), with only 3% of malignant cases. The GLLAMM analyses revealed further potential factors on the status of malignancy, tumour origin and tumour location., Conclusion: Most soft tissue tumours in the hand and wrist are benign. This can guide workup and counselling of patients before the operation. While malignant tumours are uncommon, they have the potential for significant morbidity and mortality if not appropriately evaluated or treated. The application of GLLAMM analyses showed that age, ethnicity and gender were significant predictors of malignancy., (Copyright © 2024 Copyright: © 2024 Singapore Medical Journal.)

Traumatic foveal tears of the triangular fibrocartilage complex lead to ulnar-sided wrist pain and instability, resulting in painful motion and loss of grip strength with a severe impact on the overall function of the upper limb. Surgical repair is nothing new and has traversed through the realm of open repair to arthroscopic assisted to all arthroscopic repair techniques over the many decades, with arthroscopic repairs showing better visualization, lesser trauma, and equally favorable patient outcomes. Techniques had varied from using trans osseous tunnels to bone anchors, with or without the usage of special jigs. Here, we describe a simple and fast 3 portal arthroscopic technique of repairing the torn foveal insertion of the triangular fibrocartilage complex using a bone anchor inserted under arthroscopic and fluoroscopic guidance into the fovea. Both the dorsal and volar limbs of the triangular fibrocartilage complex are repaired arthroscopically, resulting in a strong anatomic repair resulting in a stable and pain-free wrist., Competing Interests: Conflicts of Interest and Source of Funding: The authors report no conflicts of interest and no source of funding., (Copyright © 2023 Wolters Kluwer Health, Inc.

Substance tears of the triangular fibrocartilage complex (TFCC) can occur secondary to trauma of the wrist. On the dorsal periphery, they are considered Palmer 1B tears or Atzei class 1 tears. If along the radial side, they can manifest as a tear of the central disc, classified as a Palmar class 1A tear. If it involves the ligaments, it is stated as a pre-1D tear as per the new classification system by Luchetti and colleagues. Multiple excellent repair techniques exist in the current literature for dorsal peripheral tears and even for those in the substance of the TFCC, whereas there are successful evolving techniques of repair of avulsed tears and those involving the substance of the ligaments on the radial side adjacent to the sigmoid notch. Here, we describe our technique of repairing substance tears of the TFCC arthroscopically without the need for any specialized equipment apart from the basic arthroscopy set. The technique was conducted in a patient with a transverse substance tear on the radial side of the triangular fibrocartilage involving the central disc with complete resolution of symptoms. It is a simple technique, which can be used to repair class 1B peripheral tears and pre-1D tears in the substance of the TFCC., Competing Interests: Conflicts of Interest and Source of Funding: The authors report no conflicts of interest and no source of funding., (Copyright © 2023 Wolters Kluwer Health, Inc.

Radial-sided tears of the triangular fibrocartilage, though uncommon, can still be a reason for ulnar-sided wrist pain, and, at times, instability of the distal radioulnar joint. Historically, it has been believed that because of the paucity of vascularity along the radial edge of the triangular fibrocartilage complex (TFCC), any form of repair will not lead to healing, thus stating it to be an exercise in futility. Current literature deftly argues against this previously prevailing concept and supports the need of repair in case of symptomatic radial-sided TFCC tears. In our study, we describe an all-arthroscopic technique of repairing radial-sided tears using a bone anchor which can be a fast and simple procedure in the hands of an orthopaedic or hand surgeon trained in arthroscopy. This technique also circumvents the risk of injuring the superficial radial nerve and other radial-sided structures which are stated complications of the current arthroscopic repairs., Competing Interests: Conflict of Interest None declared., (Thieme.

Septic arthritis of the wrist though decidedly rare can lead to severe consequences with loss of form and function of the hand. The approach to diagnosis and treatment remains challenging and may need multiple surgeries, prolonged hospital stays along with intravenous antibiotics for restitution of a pain and disease-free functioning wrist. Arthroscopic washout of the wrist joint, has paved the way for a less invasive and more effective approach to the management of the condition reducing the number of operations needed and the need for open wrist washout. In our paper, we describe in addition to arthroscopic washout of an infected wrist joint the insertion of irrigation catheters followed by continuous irrigation with normal saline through the catheters using an infusion pump for 5 days leading to resolution of symptoms without further surgical interventions., Competing Interests: Conflict of Interest None declared., (Thieme.

Singapore as an island nation is one of three countries in the world that has hand and reconstructive microsurgery (HRM) as an independent specialty. The 52 accredited hand surgeons serving a population of 5.7 million facilitate hassle free access to patients. Hand surgery historically is rooted very much in orthopaedic surgery as in most Asian countries with more than five decades of rapid evolution. Singapore pioneered a structured and systematic training program for HRM and the local surgeons have contributed significantly to the body of knowledge in hand surgery with targeted research and publications with three surgeons being awarded international recognition for their contributions. Singapore continues to contribute significantly to surgical volunteerism regionally through active involvement in the training of regional surgeons through their sustainable volunteer activities and through international fellowships in Singapore hospitals. The future of hand surgery in Singapore will be more competency and multidiscipline based on community-centered approach., Competing Interests: Conflict of Interest None declared., (Society of Indian Hand & Microsurgeons.
