Sports Medicine: Just the Facts

with modification of equipment as needed to decrease
load per stroke, adjust oar/foot height, or even switch
side rowed (for sweep rowers) (Karlson, 2000).

OVERUSE KNEE INJURIES



  • The rowing stroke maximally loads the knee when it is
    in the fully flexed position. As a result, patellofemoral
    pain is a common complaint among rowers. As with
    patellofemoral problems in other sports, this is more
    common in women and in those with anatomy that
    predisposes them to abnormalities in patellar tracking.
    Tracking problems can be further exacerbated by the
    position of the shoes fixed in the rowing shell. Their
    height, spacing, or orientation may be mechanically
    inappropriate for the rower’s anatomy, resulting in
    increased symptoms (Karlson, 2000).

  • Usual treatment of patellofemoral pain, focusing on
    strengthening of the vastus medialis muscle to
    improve patellar tracking is recommended. Shoe posi-
    tion should be checked and modified if not appropri-
    ate for the athlete.


TENDINITIS (PATELLAR, QUADRICEPS,
AND FOREARM)


•Tendinitis can occur in the patellar or quadriceps
tendon from repeated flexion/extension with the
rowing stroke. Pain is noted over either tendon,
worsened by use, and relieved by rest. Usual treat-
ment modalities are employed for relief of symptoms,
with a focus on modifying training and equipment
errors.



  • The rowing stroke predisposes to forearm tendinitis in
    the dorsal wrist both from tightly gripping the oar
    during the stroke and from feathering the oar at the
    finish. Feathering requires rapid extension of the
    wrist, which further stresses an already strained fore-
    arm. Rowers will complain of pain in the dorsal wrist,
    specifically at the intersection of the first and third
    dorsal wrist compartments (Karlson, 2000; Edgar,
    1995; Fulcher, 1998). Physical examination will
    reveal pain and swelling at this location, and in more
    severe cases crepitance may be noted.
    •Treatment of forearm tendinitis involves relative rest
    as well as technique modification. Medical modali-
    ties, such as ice, brief immobilization, nonsteroidal
    anti-inflammatory medications, and on occasion local
    steroid injection into the affected tendon sheath may
    all be employed (Fulcher, 1998). Technique modifica-
    tion involves stressing a looser grip on the oar, as well
    as a grip that places the wrist in as flat a position as
    possible (Karlson, 2000).


NERVE ENTRAPMENT SYNDROMES

•A number of different nerve entrapment syndromes
are seen in rowers. These range from digital nerve
compression in individual fingers to carpal tunnel
syndrome in the upper extremity and frank sciatica in
the lower extremity.


  • Digital nerve compression results from a tight grip on
    the oar with direct pressure on the neurovascular
    bundle. Equipment and grip modification can alleviate
    the vast majority of these cases.

  • Carpal tunnel syndrome is also frequently the result of
    an overly tight grip on the oar as well as repeated
    extension of the wrist at the finish of the stroke. In
    addition to standard treatment, technique modifica-
    tion, involving a looser grip as well as equipment
    modification, with shaving the oar handle to give it a
    smaller diameter may help with these symptoms.

  • Sciatica can result from an improperly fitted seat that
    places pressure on the sciatic nerve. Additionally,
    there are small holes in the seats of rowing shells
    designed to fit the ischial tuberosities as the rower
    moves through the rowing stroke. If the holes are
    improperly spaced for the individual rower, nerve
    compression can result with associated numbness.
    This is especially common if women use seats
    designed for men that don’t accommodate their wider
    pelvis (Karlson, 2000).


RIB STRESS FRACTURE


  • Stress fractures of the ribs have been seen with
    increasing frequency in rowers (Hickey, 1997;
    McKenzie, 1989; Brukner and Khan, 1996; Christian
    and Kanstrup, 1997). This is thought to be secondary
    to equipment changes that have put more loads on the
    oar during the stroke (Karlson, 1998). Thought to be
    caused by the pull of the serratus anterior muscle on
    the scapula during the rowing stroke, these fractures
    are seen most frequently in the posteriorlateral region
    of ribs 5–9 (Karlson, 2000; 1998).

  • Rib stress fracture usually presents with slow onset
    of chest wall pain in the posteriorlateral location. As
    with other stress fractures, pain is initially only with
    the inciting activity, but will progress to pain at rest
    if the overuse continues. Ultimately, a bony callus
    may be noted at the site of the stress fracture.
    Diagnosis may be made with a plain film demon-
    strating callus formation, or a bone scan in question-
    able cases.
    •Treatment for rib stress fracture, as with most other
    stress fractures, involves rest, frequently for up to 6
    weeks to allow complete healing (Karlson, 2000;
