Flexor Digitorum Superficialis Course, Plus. [23], Tendon repair strength of at least four-strands is needed to withstand the forces of true active motion[23], Moderate to high level evidence that place-and-hold exercises provide better outcomes than passive flexion protocols, including Kleinert and modified Kleinert protocols, in patients with two- to six-strand repairs[23], In patients older than 30 years with a two-strand repair - greater total active motion was achieved at 12 weeks with a true active protocol than those who followed a passive flexion protocol[23], Well-designed intervention studies are necessary to support the movement towards progressive protocols with true active motion and decreased immobilisation of the wrist.[23]. It also assists in flexion of the metacarpophalangeal (MCP) joints of digits 2nd to 5th. Superficial muscle that flexes (bends) the fingers. commonly results from volar lacerations and may have concomitant neurovascular injury, stimulated by surrounding synovial fluid and inflammatory cells, implicated in the formation of scarring and adhesions, Fibroblastic proliferation with disorganized collagen, shares a common muscle belly in the forearm, index and long fingers are innervated by the AIN of the median nerve, ring and small fingers are innervated by the ulnar nerve, individual muscle bellies exist in the forearm, FDS to the small finger is absent in 25% of people, located within the carpal tunnel as the most radial structure, innervated by the AIN of the median nerve, inserts on the base of the second metacarpal, closest flexor tendon to the median nerve, inserts on the pisiform, hook of hamate, and the base of the 5th metacarpal, located at the level of the proximal phalanx where FDP splits FDS, thicker and stiffer than cruciate pulleys, most important pulleys to prevent flexor tendon bowstringing, allows the annular pulleys to approximate each other during digital flexion, A2 contributes least to arc of motion of thumb, most important pulley to prevent flexor tendon bowstringing (along with A1 pulley), occurs when flexor tendons are located within a sheath, it is the more important source distal to the MCP joint, nourishes flexor tendons located outside of synovial sheaths, vincular systemosseous bony insertions, reflected vessels from the tendon sheath, and longitudinal vessels from the palm, osseous bony insertionsreflected vessels from the tendon sheath, and longitudinal vessels from the palm, FDS insertion to distal palmar crease/proximal A1 pulley.
