lacertus. A single specimen was collected co-occurring with three species, B.
Gobius lacertus Poey, in Poey, 1860: 278 (type locality Cuba).
USNM 120413, Gobius lacertus holotype, 74 mm SL, Cuba.
lacertus specimens investigated in our study were collected from Tobago, Belize, Panama, Curacao, Puerto Rico, the Bahamas, and the Florida Keys.
The physical examination and radiographs can be equivocal due to the strength of the uninjured brachialis muscle and the stabilizing power of the lacertus
(28,29) The tendon does not retract if the bicipital aponeurosis (lacertus
fibrosis) remains intact.
(8) The lacertus fibrosis is composed of three layers that originate from the short head of the tendon and assists in stabilizing the tendon distally.
On physical examination, the normal contour of the distal biceps may still appear to be intact if the lacertus fibrosis is not torn or if the swelling or hematoma hides the "Popeye" deformity (Fig.
The integrity of the lacertus fibrosis can determine whether the biceps tendon can be reattached to the radial tuberosity.
In eight of the 10 patients, adequate mobilization of the biceps tendon was achieved by releasing adhesions, sectioning the lacertus fibrosus, performing relaxing incisions to the epimysium, or applying traction to the distal biceps stump for several minutes and releasing the tourniquet.
Surgical exploration revealed the tendon to be completely avulsed from the radial tuberosity using minimal retraction, as it was held by the lacertus fibrosus.
Fortunately, direct repair was accomplished as there was only minimal retraction of the tendon held by the lacertus fibrosus.
