The tendon healing time and stage will influence the type of rehabilitation exercises to commence with. The medial epicondyle of the humerus in addition to sections of the ulna and radius. loss of active flexion strength or motion of the involved digit(s), evidence of malalignment or malrotation may indicate an underlying fracture, assess skin integrity to help localize potential sites of tendon injury, look for evidence of traumatic arthrotomy, passive wrist flexion and extension allows for assessment of the, normally wrist extension causes passive flexion of the digits at the MCP, PIP, and DIP joints, maintenance of extension at the PIP or DIP joints with wrist extension indicates flexor tendon discontinuity, active PIP and DIP flexion is tested in isolation for each digit, important given the close proximity of flexor tendons to the digital neurovascular bundles, partial lacerations < 60% of tendon width, may be associated with gap formation or triggering, flexor tendon reconstruction and intensive postoperative rehabilitation, minimal interference with tendon vascularity, sufficient strength throughout healing to permit application of early motion stress to the tendon, delayed treatment leads to difficulty due to tendon retraction, incisions should always cross flexion creases transversely or obliquely to avoid contractures (never longitudinal), meticulous atraumatic tendon handling minimizes adhesions, linear relationship between strength of repair and # of sutures crossing repair, 4-6 strands provide adequate strength for early active motion, high-caliber suture material increases strength and stiffness and decreases gap formation, ideal suture purchase is 10mm from cut edge, core sutures placed dorsally are stronger, improves tendon gliding by reducing the cross-sectional area, improves strength of repair (adds 20% to tensile strength), allows for less gap formation (first step in repair failure), produces less gliding resistance than other techniques, theoretically improves tendon nutrition through synovial pathway, clinical studies show no difference with or without sheath repair, most surgeons will repair if it is easy to do, historically believed to be critical to preserve, however recent biomechanical studies have shown, can be incised with little resulting functional deficit, 100% of A4 can be incised with little resulting functional deficit, in zone 2 injuries, repair of one slip alone improves gliding, weakest between postoperative day 6 and 12, repair site gaps > 3mm are associated with an increased risk of repair failure, usually epinephrine 1:100,000 and 7mg/kg lidocaine, 1% lidocaine with 1:100,000 epi for a 70kg person, dilute with saline (50:50) to get 0.5% lidocaine, 1:200,000 epi, if 100-200cc is needed for large fields (tendon transfer, spaghetti wrist), dilute with 150cc saline to get 0.25% lidocaine and 1:400,000 epi, add 10cc of 0.5% bupivacaine with 1:200,000 epi, allows intraoperative assessment for repair gaps by getting awake patient to actively flex digit, reduces need for postop tenolysis by allowing intraoperative assessment of whether repair will fit through pulleys, allows on-the-spot debulking of bunched repairs, allows division of A4 pulley and venting (partial division) of A2 pulleys, allows repair of tendons inside tendon sheaths as patients can demonstrate that the inside of the sheath has not been inadvertently caught, begin active midrange motion after day 3 (form a partial fist with 45 degree flexion at MP, PIP and DIP joints, or "half a fist 45/45/45 regime"), full passive range of motion of adjacent joints, only perform if the flexor sheath is pristine and the digit has full ROM, Stage I - SR is placed to create a favorable tendon bed, Stage II (3-4 months) - SR is retrieved and a tendon graft is placed, through the mesothelium-lined pseudosheath, pulvertaft weave proximally and end-to-end tenorrhaphy distally, SR is placed in the flexor sheath, pulleys are reconstructed (as needed), and a loop between the proximal stumps of FDS and FDP is created in the palm, SR is retrieved, FDS is cut proximally and reflected distally through the pseudosheath and either attached directly to FDP stump or secured with a button, graft (FDS) size is known at the time of silicone rod selection, less graft diameter-rod diameter mismatch, fewer adhesions than extrasynovial grafts, relies on only 1 tenorrhaphy site (distal or proximal) to heal at any one time (vs. Hunter technique where 2 tennoprhaphy sites are healing simultaneously), graft tensioning is at the distal end during stage II, the proximal end has already healed after stage I, extensor digitorum longus to 2nd-4th toes, pulley reconstruction should occur first if a tendon graft is being used, subsequent tenolysis is required more than 50% of the time, localized tendon adhesions with minimal to no joint contracture and full passive digital motion, may be required if a discrepancy between active and passive motion exists after therapy, wait for soft tissue stabilization (> 3 months) and full passive motion of all joints, careful technique to preserve A2 and A4 pulleys, Postoperative controlled mobilization has been the major reason for improved results with tendon repair, limits restrictive adhesions and leads to increased tendon excursion, indicated for children and non-compliant patients, casts/splints are applied with the wrist and MCP joints positioned in flexion and the IP joints in extension, active finger extension with patient-assisted passive finger flexion and static splint, active finger extension with dynamic splint-assisted passive finger flexion, adds active wrist motion which increases flexor tendon excursion the most, moderate force and potentially high excursion, dorsal blocking splint limiting wrist extension, perform place and hold exercises with digits, most common complication following flexor tendon repair, perform if 4-6 months after tendon repair and significant loss of excursion, if < 1cm of scar is present, resect the scar and perform primary repair, if > 1cm of scar is present, perform tendon graft, if the sheath is intact and allows passage of a pediatric urethral catheter or vascular dilator, perform primary tendon grafting, if the sheath is collapsed, place Hunter rod and perform staged grafting, Lunate Dislocation (Perilunate dissociation), Gymnast's Wrist (Distal Radial Physeal Stress Syndrome), Scaphoid Nonunion Advanced Collapse (SNAC), Carpal Instability Nondissociative (CIND), Constrictive Ring Syndrome (Streeter's Dysplasia), Thromboangiitis Obliterans (Buerger's disease).

List 7 foot NBA players and basketball players over 7ft. This position does not put any stretch or tension on the tendons. Although not all arm care programs have gone through the rigors of studying their effectiveness in the field, these studies by Sakata et al.8,9 highlight the potential impact of using arm care interventions. 5th Edition. Here we explain the symptoms,. The supraspinatus reaches 60% MVC from cocking to acceleration, middle deltoid reaches 59% MVC and teres minor reaches 84% MVC during deceleration.2 A review of the literature supports the scaption exercise as a general shoulder strengthening exercise.12,18,22 The highest activation occurs in the supraspinatus 32-64% MVC, middle deltoid 38-52% MVC, and teres minor 39-110% MVC.12,18,22,23, This exercise was chosen for activation of infraspinatus. An electromyographic analysis of the upper extremity in pitching. After the surgery, the hand and forearm are immobilised in a splint that is placed over the bandages with the wrist and fingers in a slightly bent position, in order to protect the repair.[14]. Once the wound is healed, scar management can commence. There are several different ways to strengthen the finger flexors using the power web. The NISMAT Arm Care program is based on current EMG research using no more than elastic resistance and addressing each of the key components of the pitching motion. A person can exercise the flexor digitorum superficialis by performing wrist curls. This program was designed to utilize elastic-resistance exercises with no additional equipment required. Fukunaga et al.25 showed the ulnar deviation with elastic resistance reached 40% MVC. WebPlacing the hand in a non-removable cast with the MP joints blocked in extension focuses all active motion on the one movement needed to regain maximum glide and differential glide within zone 2: active IP joint flexion. Available from. Available from: Tan J, Kim CH, Lee HJ, Chen J, Chen QZ, Jeon IH.

A new examination method for anatomical variations of the flexor digitorum superficialis in the little finger. Flexor carpi ulnaris reaches 112% MVC during the acceleration stage of pitching.2 The flexor carpi ulnaris is also considered a secondary stabilizer of the ulnar collateral ligament. Early pioneers broke down the EMG activity of each muscle during each pitching phase, which led to the development of the original gold standard of arm care programs: the Throwers Ten. But, for the benefit of your posture, I recommend doing this drill while sitting in a chair. [2] Andlucky youthats exactly what Ive done here. It is mandatory to procure user consent prior to running these cookies on your website. Its also little surprise that a muscle this large (large for the forearm, that is) has two distinct heads. During the pitching motion, the infraspinatus peaks muscle activation during the late cocking phase (74%), while the teres minor muscle activity peaks during the deceleration stage (84%).2 This exercise has been shown to activate the infraspinatus between 50-88% MVC, while teres minor activation will reach a lower level of 39% MVC.5,12,18,19 The NISMAT Arm Care program encourages this exercise to start with a scapular retraction during the row. Kim Bengochea, Regis University, Denver. 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. Philadelphia, PA: Lippincott Williams & Wilkins. Peck FH, Roe AE, Ng CY, Duff C, McGrouther DA, Lees VC. The secondary muscles worked are the flexor digiti minimi, which flexes the little finger, the flexor indicis, which flexes the index finger and the flexor pollicis longus and brevis and opponens pollicis which all flex the thumb. When deciding how to best train a muscle, its important to think about the functions that that muscle is responsible for. Strengthening exercises can include activities such as: Squeezing Theraputty, Play-doh or a sponge in hot water, Can progress to wrist weights and Theraband if appropriate, for complete upper limb strengthening.
