Silicone Gel Sheeting for Treatment of Scars

June 23, 2017
Silicone gel sheeting (SGS) has been used in scar therapy for over 30 years, during which its efficacy has been the subject of numerous clinical evaluations. While the exact mechanisms by which SGS improves scar healing are yet to be fully agreed upon, its ability to do so remains largely undisputed. As such, topical silicone gel treatments seem to remain the first point of clinical recommendation in scar management. Carpal tunnel scar The formation of scar tissue is generally characterised by...

Ruptured Flexor Tendon

June 1, 2017
Ruptured Flexor Tendon The flexor digitorum profundus (FDP) is a muscle that has 4 tendons with one tendon attaching to the end of each finger on the palm side of the hand. A ruptured FDP tendon results in a person being unable to actively bend the end of their finger. This injury can occur when a player grabs another player's jersey with the tips of one or more fingers while that player is pulling or running away. The force of this...

Mallet Finger

June 1, 2017
Ruptured Extensor Tendon A mallet finger injury is suspected when the end of the finger is bent and cannot straighten actively. This injury can happen to anyone when an unyielding object (like a ball) strikes the tip of a finger or thumb and forces it to bend further than it is intended to go. This causes an injury to the tendon that straightens the end of the finger. Less often, the cause is a fracture at the bottom of the...

Why Do Old Injuries Ache in the Cold?

July 5, 2016
Ever noticed how an old injury aches in the wintery weather? The idea that certain aches and pains correspond with, and can even predict the weather is widespread, and has been around since at least the days of ancient Greece. Hippocrates was the first to note the phenomenon, in about 400 B.C. Unfortunately over the past 2,400 years, researchers have not come up with a solid evidence-based explanation as to why this happens. The current accepted explanation for bad-weather-related aches is...

Imaging for Diagnosis of Bony Injury in the Wrist

July 5, 2016
Pain in the wrist is a diagnostic challenge for hand therapists, surgeons and radiologists alike because of the small and complex anatomical structures involved. There are 29 bones that together make up the supporting framework of the hand and wrist. Advances in imaging modalities (e.g. xrays, CT scanners and MR Imaging) have aided specialists in the diagnosis of fractures. Current research has focussed on the sensitivity and specificity of the results obtained by these investigations. Sensitivity measures the proportion of actual...

Fingertip Injuries

July 5, 2016
Injuries to the fingertips are common. They can occur when a fingertip slams in a car door, is damaged while chopping vegetables or injured when clearing debris from a lawnmower. In the paediatric population fingertip injuries account for two thirds of all hand injuries with the most common mechanism of injury being a crush between a door and its frame. In contrast, the adult population predominantly suffer lacerations to fingertips followed by crush injuries. The most commonly involved digits are the...

Thumb extensor tendon (EPL) rupture

July 5, 2016
What is the EPL tendon? The long extensor tendon to the thumb is called the Extensor Pollicis Longus (EPL). This tendon straightens the end joint of the thumb (thumbs up or hitch hikers sign – see Figure 1) and also helps pull the thumb in towards the index finger. Why does it rupture? This tendon is vulnerable to rupture in the tunnel at the wrist. There are two situations that are associated with rupture. The first is after a fracture of...
