70 mm radius constructs are used to treat hypoplastic
thorax syndromes.
A hypoplastic low thorax volume (as seen with Jeune’s Syn-
drome) requires the use of a 70 mm rib-to-rib construct
(70 mm implants include: Cranial Rib Support, Caudal Rib
Support, Extension Bar). These constructs are placed bilater-
ally in separate procedures.
Surgical technique for 70 mm radius constructs
After inserting both the Cranial and Caudal Rib Support, free
the central segment of the selected hemithorax by making
transverse incisions in the periosteum to enable anterior and
posterior osteotomies.
Perform anterior and posterior osteotomies from ribs three
through eight. Distract the mobilized chest segment postero-
laterally.
Place retractors subperiosteally to protect the underlying
lung.
Choose 2–3 sites in the central portion of the mobilized seg-
ment to insert the 2.0 mm Titanium Rod which will hold
the ribs to the construct. Bend the rod to form a gentle curve
using the Wire Bending Pliers.
Assemble the construct as stated in the rib-to-rib construct
section.
After the construct has been completely assembled and
locked, use the Pliers to again grasp rods and contour
around implanted rib-to-rib construct, leaving space to re-
move the locks and expand the construct.
