A multivariate analysis on characteristics of hand and wrist tumours: a multiethnic study.

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.

Fetal congenital heart diseases: Diagnosis by anatomical scans, echocardiography and genetic tests.

Objective: To determine the distribution of major fetal congenital heart diseases (CHDs) diagnosed antenatally during routine second-trimester obstetric anatomical scans in an unselected population at a single tertiary centre and to characterise and stratify risk factors, genetic diagnosis and long-term health at 4 years old.

Method: A single-centre cohort study of all major fetal CHDs detected on routine obstetric fetal anatomical ultrasound scans between January 2014 and December 2017 was performed in an unselected population. Demographic details, fetal echocardiogram reports, genetic test results, delivery outcomes and postnatal progress were stratified by CHD subtype.

Outcomes of Autologous and Synthetic Bone Grafts in Locking Plate Fixation of Comminuted Distal Radius Fractures.

Background The introduction of locking plate technology has improved the feasibility of distal radius fracture fixation without the need for bone grafting, yet challenges persist in cases of severely comminuted fractures and small, unstable intra-articular fragments. This study aimed to assess the outcomes of bone grafting in severely comminuted distal radius fractures treated with locking plates. Methods We performed a retrospective analysis involving 450 patients who underwent distal radius fracture fixations.

Secondary Intention Healing for Fingertip Amputations in a Tropical Climate.

Various studies have examined occlusive dressings in fingertip amputations and reported good outcomes. Occlusive dressing preserves appropriate pH, cell accumulation and moisture for healing, thereby limiting scar formation and deformity. To our knowledge, no study was performed in tropical Asia.

An All-Arthroscopic Technique of Repairing Foveal Tears of the Triangular Fibrocartilage Complex Using a Bone Anchor-Repair Made Simple.

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.

Fingertip Replantation: Surgical Technique, Tips, and Tricks.

Replantation of fingertip amputations restores the original tissue and is the ideal treatment to provide the best aesthetic and functional outcome. However, successful fingertip replantation is considered challenging because it requires supermicrosurgery techniques. This article provides a detailed surgical technique for fingertip replantation and the authors' preferences and recommendations.

An All-arthroscopic Technique of Repair of Substance Tears of the Triangular Fibrocartilage Complex in Symptomatic Patients.

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.

The right turn around: Penrose tourniquet application in paediatrics.

Introduction: Commercially available tourniquets are ill-suited for paediatric patients with limb circumferences smaller than the required mechanism, forcing surgeons to improvise. This study aimed to quantify pressures exerted by the Penrose tourniquet when applied on a phantom model and evaluate the intra-/inter-rater reproducibility of the technique previously proposed.

Methods: Eight calibrated pressure sensors were distributed evenly along the inner and outer circumference of a silicon-based model.

Symptomatic Radial-Sided Tears of the Triangular Fibrocartilage Complex: An All-Arthroscopic Repair Using Bone Anchors.

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.

The Effect of Hand Dominance, Age, Gender, Fracture Comminution and ASA Status on Time to Fracture Healing Following Surgical Fixation of Distal Radius Fractures.

There is recent renewed interest in the effect of hand dominance on distal radius fractures. Current studies focus on functional or patient-reported outcomes, with lack of studies pertaining to radiological outcomes. The primary aim of this study is to examine the effect of hand dominance on time to fracture healing following surgical fixation of distal radius fracture.

Arthrodesis for Primary Osteoarthritis of Trapeziometacarpal Joint Using Multiple Kirschner Wires and Tension Band Wire in Female Patients Older than 40.

The purpose of this study was to evaluate the results of arthrodesis with multiple Kirschner (K)-wires and tension band wire for primary osteoarthritis of trapeziometacarpal (TM) joint in female patients aged 40 years or older. We retrospectively obtained data regarding all female patients 40 years or older who underwent TM joint arthrodesis for TM joint osteoarthritis with K-wires and tension band wire over a 10-year period from 2009 till 2019. Thumb length, active range of motion (ROM) at the metacarpophalangeal (MCP) joint, active ROM of radial and volar adduction and abduction and key pinch strength was measured.

Renal impairment and time to fracture healing following surgical fixation of distal radius fracture.

Introduction: Despite the prevalence of renal impairments, the existing literature examining fracture healing in the upper limb in patients with renal impairment is sparse. This study hence aims to investigate the effect of renal impairment on time to fracture healing after distal radius fracture fixation surgery.

Materials And Methods: Patients above 50 years old who underwent distal radius fracture fixation via volar plating were included.

Tension Reducing Muscle Stretch Protocol to Obtain Full Distal Tendon Excursion: A New Rehabilitation Protocol after Flexor Tendon Repair.

: Flexor tendon rehabilitation protocols minimize repair tension by limiting range of movement to prevent tendon rupture. The resultant muscle contracture inhibits finger extension, increases resistance in tendon gliding distally, and progress to proximal interphalangeal (PIP) joint flexion contracture. This study describes our new rehabilitation protocol, the Tension Reducing Muscle Stretch (TRMS), designed to prevent flexor muscle contracture and obtain full distal tendon excursion.

Elbow flexion strength and contractile activity after partial ulnar nerve or intercostal nerve transfers for brachial plexus injuries.

We compared the outcomes of 23 partial ulnar nerve and 15 intercostal nerve transfers for elbow flexion reconstruction in patients with C56 or C567 brachial plexus injuries using manual muscle power, dynamometric measurements of elbow flexion strength and electromyography. The range of elbow flexion and muscle strength recovery to Grade 3 or 4 were comparable between the two groups. The patients with C567 injuries had significantly stronger eccentric contraction after the partial ulnar nerve transfer than after the intercostal nerve transfer ( < 0.

The double muscle gastrocnemius-soleus flap in resurfacing large lower limb defects: Modifications and outcomes.

Introduction: Larger soft tissue defects over critical areas of the lower limb involving the knee and proximal two thirds of the tibia present a challenge to the reconstructive surgeon. Options include a large free flap or pedicled local flaps. The gastrocnemius or soleus flap alone is not sufficient.

Characterization of the hemodynamic wall shear stresses in human umbilical vessels from normal and intrauterine growth restricted pregnancies.

Significant reductions in blood flow and umbilical diameters were reported in pregnancies affected by intrauterine growth restriction (IUGR) from placental insufficiency. However, it is not known if IUGR umbilical blood vessels experience different hemodynamic wall shear stresses (WSS) compared to normal umbilical vessels. As WSS is known to influence vasoactivity and vascular growth and remodeling, which can regulate flow rates, it is important to study this parameter.

Management and Outcomes of Fetal Hydrops in a Tertiary Care Centre in Singapore.

: Fetal hydrops is a serious condition which can be caused by immune and non-immune aetiologies. We aimed to review the management of fetal hydrops at our hospital. : A retrospective review of all cases of fetal hydrops diagnosed in our institution from 2006 to 2013 was carried out.

Characterization of the in vivo wall shear stress environment of human fetus umbilical arteries and veins.

The endothelial cells of the umbilical vessels are frequently used in mechanobiology experiments. They are known to respond to wall shear stress (WSS) of blood flow, which influences vascular growth and remodeling. The in vivo environment of umbilical vascular WSS, however, is not well characterized.
