Transverse connection for spinal column corrective devices

An apparatus for interconnecting a pair of longitudinal members extending substantially parallel to each other and connectable with vertebrae of a spinal column, said apparatus comprising:

• a first connector member connectable with one of the longitudinal members, said first connector member including a hook portion extendable around a portion of the one longitudinal member;
• first means for releasably connecting the one longitudinal member to said hook portion of said first connector member;
• a second connector member connectable with the other longitudinal member, said second connector member including a hook portion extendable around a portion of the other longitudinal member;
• means for interconnecting said first and second connector members extending between said first and second connector members and transverse to the longitudinal members;
• second means for releasably connecting said interconnecting means to said first connector member after said first connecting means has connected said hook portion to the one longitudinal member;
• third connecting means for releasably connecting the other longitudinal member to said hook portion of said second connector member, said third connecting means comprising a set screw threadably engaging said second connector member and engageable with the other longitudinal member to clamp the other longitudinal member to said second connector member;
• and
• fourth connecting means for connecting said interconnecting means to said second connector member, said fourth connecting means comprising a nut threadably engaging said set screw and engaging said interconnecting means to clamp said interconnecting means to said second connector member.

• first means for releasably connecting the one longitudinal member to said hook portion of said first connector member;
• a second connector member connectable with the other longitudinal member;
• means for interconnecting said first and second connector members extending between said first and second connector members and transverse to the longitudinal members, said interconnecting means comprising an elongate plate extending between said first and second connector members;
• and
• second means for releasably connecting said interconnecting means to said first connector member after said first connecting means has connected said hook portion to the one longitudinal member.

An apparatus for interconnecting a pair of longitudinal members extending substantially parallel to each other and connectable with vertebrae of a spinal column, said apparatus comprising:

• a member extendable transverse to the longitudinal members;
• and
• first and second connector means for connecting said member to the longitudinal members;
• said member including first and second portions extending from a surface of said member, said surface of said member defining a bottom of a recess for receiving said first connector means, said first and second portions having surface means defining sides of the recess for receiving said first connector means, said first connector means engaging said surface of said member and said surface means defining said sides of the recess to prevent pivoting of said member relative to said first connector means.
