The goal of any arm care program is to not only show strength improvements, but also show the desired effects on injuries. The post-surgical wound may be dressed with a basic silicone dressing (products such as Mepitel may be used). Release the gripper, but be sure to resist the tension on your way back to the starting position. Here we explain, Achilles tendonitis heel drop exercises have proven to be very successful for chronic Achilles tendon pain.

Increased temperature around wound or fever, Especially in patients who have had FDS and FDP tendon repairs, If a patient develops a contracture, they will sometimes need dynamic splinting about 8 - 10 weeks post-surgery. For example, after a transfer of the flexor digitorum superficialis (FDS) tendon of the ring finger to the thumb to restore opposition, a wrist-based thumb spica orthosis may be used to position the wrist in 10 to 20 degrees of flexion with thumb opposition. If the splint does need to come off, the patient needs to be educated about safe hand positioning. the type of splint design that patient will need, Zone I - distal to the flexor digitorum superficialis (FDS), Zone II - from the FDS insertion to distal portion of the A1 pulley, Zone III - from the A1 pulley to the transverse carpal ligament, Zone I - distal to the interphalangeal joint (IP) in the thumb, Zone II - between the metacarpophalangeal (MCP) and interphalangeal (IP) joints, Zone III - proximal to the metacarpophalangeal (MCP) volar/palmar flexion crease, Loss of active flexion strength or motion of the involved digit(s), Pain when attempting to flex the involved digit, Flexor Digitorum Profundus (FDP) tendon - the patient is unable to flex the distal interphalangeal joint (DIP) in isolation, Flexor Digitorum Superficialis (FDS) tendon - isolate the involved/affected finger and ask the patient to flex the proximal interphalangeal joint (PIP), Flexor Pollicis Longus tendon - flexing the interphalangeal joint (IP) joint of the thumb in isolation, lasts from day one to day seven post-operatively, in this stage, fibroblasts produce type III collagen and macrophages help initiate healing and remodelling, this runs from day 8 to about three weeks post-operatively, tissue modelling via large amounts of disorganised collagen happens during this stage, angiogenesis also happens during this stage, occurs up until about 18 months post-operatively, in this stage, tensile forces lead to tissue remodelling, and type III collagen is replaced with type I collagen, this happens in a more linear fashion, and this creates cross-linking to build strength in the tendon. The cruciform pulley system is flexible and collapsible to allow for digital flexion without deformation of the pulley system. Patients need to be aware of the necessary precautions. This happens in ball sports where a finger is forced into extension while it is being flexed or where a player grabs an opponent's shirt (jersey finger) or in activities such as rock climbing.[12]. Kim Bengochea, Regis University, Denver. Rotate top hand towards the ceiling, while keeping top elbow pinched against body, and band anchored with lower hand. Zone I, II and III injuries of the flexor digitorum profundus and/or the flexor digitorum superficialis, This promotes the arc of flexion to be activated by the long flexors, rather than the intrinsics.

Sometimes, patients have some minimal nerve damage at the time of injury, that does not need surgical repair, but through the course of the six weeks of splinting symptoms of nerve damage develop. Variant muscle to the little finger originating from the flexor digitorum superficialis. Radialis the side of the wrist where the radius is. The dumbbell can be substituted with a resistance band. For the finger flexors the zones are as follows[10][11]: Flexor tendon injuries commonly result from volar/palmar lacerations. Thorn, K. Flexor Tendon Injury Management.
