a4 pulley injury taping

The A2 pulley is the most commonly injured pulley and is very prone to injury when crimping due to the biomechanical forces present.1–9 During the rehab phase of a pulley injury, it is very important to offload the healing pulley, and tape can be a good option to get the job done. Go and chase some snow bunnies if you haven’t caught one already. Outside trying to preserve skin, taping our fingers is a debated topic among climbers, whether it is to prevent injury or offer protection when recovering from an injury. From this point forward, you now know why H-tape is the method of choice thanks to the diligent research from Dr. Schöffl and her team, and all of the collaborators that helped shed light on the topic. The results of their study showed that there were no significant increases in strength (load failure) to the A2 pulley when using tape on the cadavers. Taping allows you to climb while taking up to 10% of the strain off the affected pulley. In short, just be smart about your return to climbing, and don’t push it too much too soon. A4 15% A5 0% Biomechanical effectiveness of taping the A2 pulley in rock climbers. What taping method is recommended? Is taping useful in this situation? Note on tape type: Leukotape was used in the study and it is much stiffer than normal climber’s tape so we can assume that the tape most people use for their fingers will have slightly less of an effect as in the study. Notice the location of the H-tape “bridge”. The patient was discharged the following day on an oral course of bactrim. Go back and read Part 1 and Part 2 of my pulley injury articles to see the course of treatment.]. He connects with anyone in the extreme sports realm as a healthcare provider who has the capacity to understand their sport and assist them with their unique needs. See what works for you. Flexor tendons in the fingers attach to muscles in the forearms that pull on the tendons, bend the fingers, and allow us to crimp. These are valid concerns and due to his views, he suggests that during rehab when you begin easy climbing again, that you splint the finger at the PIP joint instead of H-tape. We can thank the Vikings, promiscuous ruffians who spliced their genome into the European community. Three bones and three hinged joints make up the finger. (check out this super helpful article explaining pulley injuries if you need a refresher for what an a4 is.) I really like Dave Macleod’s idea for early rehab to splint tape your finger at the PIP joint to limit your finger to only using open-hand gripping. Injury trends in rock climbers: evaluation of a case series of 911 injuries between 2009 and 2012. We don’t have a paywall and you don’t have to be a member to access thousands of articles, photos and videos. Damage to the flexor tendon pulleys is the most common climbing injury. Therefore, taping to prevent pulley injuries is not recommended. 23 Grade 4 injuries require a surgical repair by the loop and a half, single-loop, double-loop or double-anchor repair technique. Typically in baseball pitchers, the injury is isolated to the A4 pulley. Taping over pulleys decreased bowstringing by 2.8% and absorbed 11.0% of the force of bowstringing. Circumferential taping and the "Figure-8" method were shown to have little to no supportive effect on the pulley system. Injury. Practice this step because leaving a bridge that is too small will have less of an effect. The study examined 8 subjects with singular A2 pulley ruptures and multiple pulley ruptures of A2 and A3 pulleys.15 The researchers used standardized ultrasound to determine the tendon-bone distance and the effectiveness of various taping methods to reduce the bowstringing. This is especially true for crimps that really strain your pulleys. Protective pulley taping will be minimally effective in preventing a full pulley tendon rupture. Remember from the research experiment testing H-tape’s effect on tendon-bone distance, that it only decreased the tendon-bone distance by 16%. The objectives of this study are to characterize this injury and to describe diagnostic and therapeutic guidelines. I was pulling on a small side pull in an open-handed grip with marginal feet and heard a loud pop. The A2 pulley is typically injured in isolation but A4 pulley disruption can also occur, either in isolation or as part of a complex injury. 12. Dr. Isabelle Schöffl developed a new taping method, known as “H-taping”, to reduce tendon-bone distances (bowstringing) by supporting the finger pulleys in a different way. Subjects were placed on a standardized measuring device (see image below) in order to keep each subject’s arm in the same position for a standardized ultrasound reading. There are two main flexor tendons in each finger: one that flexes the middle phalanx, and one that flexes the fingertip. 2-7 • Training modification and prevention of initial injury is paramount in building strength to tendons, and minimizing recovery time in the case of injury. (Warme and Brooks 2000) Check out Chockstone.org for some more advise and info on taping. Someone please tell me what that is.

The results of the study showed that taping over the distal edge of A2 did not decrease bowstringing by more than 5% or absorb more than 10% of the force on the pulley. Ligaments connect and stabilize the bones, while tendons connect muscle to bone, transferring to the bone any forces created by the muscles. The A1, A3, and A5 pulleys are more flexible and attach to the volar plate, a ligament that connects two phalanges together. Dave Macleod, professional climber and author of the book, Make Or Break, has his own thoughts on pulley taping, so I’ll summarize here. Can I just go skiing for the winter and forget about it? This typically indicates the full monty of pulley damage. While many climbers tape their fingers for hard and crimpy projects using the circular taping method on the first phalanx (to support the A2 pulley) research has shown this provides little support. rockandice.com is completely free. The A1, A3, and A5 pulleys are more flexible and attach to the volar plate, a ligament that connects two phalanges together. It is probable that athletes cannot produce optimal strength in the injured finger because they don’t “trust” it anymore. … The most common injury in climbers is the A2 pulley sprain or rupture and is caused by overloading the tissue. Cut/tear the tape in half longitudinally leaving a small “bridge” in the middle. That’s better than nothing, and statistically significant, but at the end of the day it’s not a whole lot. This fact may lead to a pulley rupture thereby further increasing the bowstringing. Even so, MacLeod doubts that the support given by the H-Tape method is really significant enough to protect the pulleys and feels that the tape quickly stretches out … After that my left ring finger felt unsupported and I couldn’t weight it. The results of the study demonstrate that H-taping produces statistically significant tendon-bone distances 16% smaller compared to without tape.15 The other two taping methods, circular and figure 8, did not influence the tendon-bone distance significantly (roughly 5% and 2% respectively.) By continuing to use our site, you agree to our cookies. 2000 Feb;25(1):102-7. And taping around the A2 pulley may absorb only about a 10% of the force that is being applied to the A2 pulley. Muscle can adapt on the order of weeks, whereas ligaments and tendons may take months to years to adapt. This does not result in a very effective injury prevention method. Taping can never approximate or improve upon the effectiveness of an intact pulley system. It is not uncommon to injure more than one pulley, eg A2, A3 and A4 can be injured at the same time. Keep your eyes out for pulley rings, and if your doctor is up-to-date, maybe she or he has one for you. But that’s where the H-tape comes in to offer some pulley protection later on in rehab. Therefore, as the performance of a rock climber improves, the less effective pulley taping becomes.”12, n short, circumferential pulley taping at the distal end of the proximal phalanx can be “minimally” effective in relieving the stress on the A2 pulley, and it’s effectiveness decreases as the external force on the fingertip is increased (AKA as you pull harder on crimps.) Step 4: Tighten the proximal straps making sure to keep the 60 degree flexion. • Pulley ruptures most commonly affect the A2 and A4 sheaths, often in the third and fourth digit. He currently teaches injury prevention classes at local climbing gyms, and also provides content about the topic on his Instagram (@theclimbingpt). The A3 is easier to protect, hence the prospect of climbing is more tenable (see Bum Wraps, the truth about finger taping; No. The pulley ring does not make your finger invincible by any means. To achieve optimal results, consider buying Leukotape for rehabbing pulley injuries. Apparently you should rather consult r/climbharder about this problem, since it is full of V9 boulderers and everyone had a pulley injury before. Your burly muscles might place too much stress on your growing pulleys, leaving you at  risk of injury. Case Report: We describe a closed traumatic annular 2 (A2) through annular 4 (A4) pulley rupture with avulsion of the FDS tendon.
