2. INTRODUCTIONINTRODUCTION
• Most injuries treated non-operativelyMost injuries treated non-operatively
• Surgical treatment = indirect headSurgical treatment = indirect head
within muscle belly (only oneswithin muscle belly (only ones
operated)operated)
• Proximal injuries from direct head andProximal injuries from direct head and
distal injuries to the aponeurosis =distal injuries to the aponeurosis =
improve with time and RHB.improve with time and RHB.

12. SURGICAL TECHNIQUESURGICAL TECHNIQUE
• Blunt dissection allows to identify theBlunt dissection allows to identify the
