The spiral oblique retinacular ligament (SORL)

Volar Tenodesis for the Treatment of Swan-neck Deformity; A Systematic Review

“…The ulnar conjoint lateral band is detached proximally and routed volar to the Cleland ligament so that it lies volar to the axis of PIP joint motion; it is then attached to the flexor tendon sheath at the A2 pulley. Thompson et al (1978) 15) (Littler III) The ulnar lateral band is sutured to the proximal phalanx. Use of a tendon graft considered preferable if the lateral band is of poor quality.…”

“…27) Littler (1952), 28) first described a volar tenodesis, using a strip of the flexor digitorum superficialis (FDS) tendon inserted into the proximal phalanx; there are only limited case reports about its outcome (Littler I). The retinacular ligament reconstruction was originally described by Littler (1966), 29) (Littler II) and modified by Thompson et al (1978), 15) (Littler III) ( Table 4). Seven out of eight papers measured the post-operative PIP ROM.…”

Management of Complications of Extensor Tendon Injuries

“…The graft tension is then set and anchored into the proximal phalanx with a pull-out button. 8 An axial K-wire can be used to pin the DIP joint in a neutral position and an oblique K-wire can be used to pin the PIP joint in 10 to 15 of flexion. 9…”

Assessment and management of swan neck deformity

“…For a more secure repair, the lateral band may be routed across the palmar surface of the PIP joint and secured to the bone of the radial side of the proximal phalanx. A modification of this technique uses the uses a tendon graft [5] instead of the lateral band, if the lateral band is of poor quality. Zancolli lateral band translocation.…”
