Stable ankle Conservative Unstable ankle Surgery 2 7/6/2015 Indications Stable ankle: • Syndesmotic ruptures without injury of the deltoid ligament Conservative Management Unstable ankle • Frank diastasis or • Latent instability with proved deltoid ligament rupture Surgical Management Indications Sprains without instability: nonoperative • Short leg cast or brace • Rehab program as pain allows • Double the time to recover compared to a typical lateral ankle sprain Indications Frank diastasis: operative • Repair of the ligament? • If reduction blocked by deltoid ligament: exploration and repair Removal of interposed soft tissue • Syndesmosis screw • NWB short leg cast 3 7/6/2015 Approach for Operative Treatment Available surgical techniques: – Traditional metal screw fixation – Bioabsorbable screws – Suture-Button – Fixation with a staple – Cerclage wires – Kirschner wires Approach for Operative Treatment Syndesmotic screw – Aims to temporarily stabilize the reconstructed mortise – Potential complications • Synostosis or ossification of the distal tibiofibular joint • Impairment of full ankle dorsiflexion, limit tibiotalar range of movement in terms of rotation (Data from Experimental cadaveric studies) Approach for Operative Treatment Suture-button (TightRope®) – Similar outcome compared with the syndesmotic screw or bolt fixation – Might lead to a quicker return to work – Rate of implant removal is lower compared to the syndesmotic screw – Insufficient evidence on the long-term effects of the TightRope® 4 7/6/2015 Approach for Operative Treatment Diameter of the screw • No consensus on the optimal screw size for syndesmotic fixation (3.5 mm or 4.5 mm cortical screw) • Experimental data: screw of larger diameter provide greater resistance to an applied load Approach for Operative Treatment Number of cortices – No consensus (three or four cortices) – Four-cortical fixation: more rigidity and stability of the ankle, but higher risk of screw breakage – Three-cortical fixation: better syndesmosis biomechanics (possibility of hardware failure is diminished while the risk of loosen the screw is increased than fourcortical fixation) Approach for Operative Treatment Absorbable screw – To prevent the removal of the screw and the risks associated with this procedure – Inferior biomechanical properties compared with those of conventional metallic implants. – Good clinical outcomes – No differences compared to metallic screws 5 7/6/2015 Approach for Operative Treatment Position of the ankle during fixation – Debated issue. – Recommended to fix an injured syndesmosis with the foot in dorsiflexion to prevent a limited dorsiflexion of the ankle. – Recent studies show that the position of the ankle during syndesmotic fixation is probably irrelevant Approach for Operative Treatment Positioning of the screw • Screw should be positioned parallel to the joint line and angled about 30° anteriorly (anatomically the fibula is posterior and lateral to the tibia) • Optimal position of the screw with respect to the tibial plafond is still debated – Sproule et al.: the screw 4 cm proximal to the ankle joint – McBryde et al. less syndesmotic widening when using the screw at 2 cm than at 3.5 cm. • Screw positioned too far proximally, it can deform the fibula and the mortise is more likely to widen. Approach for Operative Treatment Retain or remove a syndesmotic screw prior to weight-bearing – Still debated – At 6–8 weeks to prevent the possibility of breakage of the screw? – Leaving the screw in place may save patients from one extra surgical procedure – Outcome appears to be similar or better when the screw is retained – Van den Bekerom et al.: removal of fourcortical screws after 6–8 weeks, and removal on indication in three-cortical screws. 6 7/6/2015 Approach for Operative Treatment – – – – – – – – – – – Syndesmotic injuries require an early recognition Late repairs are less favourable 3.5 or 4.5 screw? Proposal: 3.5 mm 3 cortices or 4 cortices? Proposal: 4 cortices in heavy patient, 3 in patients with low BMI Screw or suture-button? Proposal: both Absorbable non absorbable? Proposal: non absorbable Position for fixation Proposal: neutral to slightly dorsiflexion position Lag or positioning screw? Proposal: Both possible (prob positioning more safe) Removal of soft tissue Proposal: between 3-6 weeks Removal of screw Proposal: at 8 weeks Partial weightbearing: Proposal: 6-8 weeks Umile Giuseppe Longo - Email: ug.longo@gmail.com University Campus Bio-Medico of Rome Department of Trauma and Orthopaedic Surgery 7 7/5/2015 Operative Techniques for chronic syndesmotic injury Pieter D'Hooghe Aspetar Orthopaedic Surgery Dept, Doha, Qatar • • • • Orthopaedic Sportssurgeon ISAKOS Chair "Leg, Ankle & Foot Committee ESSKA AFAS Member No disclosures Courtesy Pau Golano - Niek van Dijk anterior and posterior inferior tibiofibular ligaments (AITFL and PITFL) as well as the interosseous tibiofibular ligament (IOL).

Current concepts review. Van den Bekerom M, de Leeuw P, van Dijk CN Injury 2009 Late syndesmotic widening Bone block transfer (screw stabilisation) • Beumer, Acta Orthop Scand, 2000 – Bone block transfer with syndesmotic screw fixation, 9 patients. – 45 months post-trauma – 9/9 are relieved of chronic instability, 2 developed dystrophy, 1 nerve entrapment • Van Dijk, Tech Foot Ankle Surg, 2006 – Bone block transfer with syndesmotic screw fixation, 6 patients. – No patient was symptom free, 2 patients had a later synostosis 9 7/5/2015 Late syndesmotic widening Bone block transfer ( + screw stabilisation) • • • Opinion: a good technique when there is a slack but intact ligament Beumer (2000) stated that even in late cases, the ligament was slack but always present Bahr (1997) stated that anatomic repair with the original (TibioFibular) ligament should be better Delayed operative treatment of syndesmotic instability. Current concepts review. Van den Bekerom M, de Leeuw P, van Dijk CN Injury 2009 Late syndesmotic widening Correction osteotomy ( + arthroscopic debridement) • Opinion: when there is a syndesmotic widening and a malunion, an osteotomy is regarded the first treatment step. • All components of the malunion should be corrected • When there is a severly disturbed ankle function, an arthrodesis should be considered. Delayed operative treatment of syndesmotic instability. Current concepts review. Van den Bekerom M, de Leeuw P, van Dijk CN Injury 2009 Late syndesmotic widening Tibiofibular fusion • Katznelson et al, Injury, 1983 – 5 patients, 3 males, 2 females, mean age 20 yr. – Ankle sprains – 10 months post trauma – 5/5 pain free, 4/5 free ROM • Opinion: this technique can be used for syndesmotic instability lasting > 6 months. Delayed operative treatment of syndesmotic instability. Current concepts review. Van den Bekerom M, de Leeuw P, van Dijk CN Injury 2009 10 7/5/2015 Chronic Syndesmotic injury TAKE HOME MESSAGE • • • • • • First consider the fibular malalignment Repair of the ligament with/when adequate remnants Otherwise a reconstruction ( ligamentoplasty )with gracilis tendon is advised When there is a slack but intact ligament: a bone block translation osteotomy is advised Debridement to aim for a fibrotic union Tibiofibular joint fusion ( synostosis with graft ) 11 7/5/2015 Syndesmotic impingment Arthroscopically resection of the distal fascicle of the AITFL should be considered when there: (1) is contact between the AITFL and the talus, (2) is increased contact between the talus and the ligament and this continued until maximum dorsiflexion with abrasion of the articular cartilage, (3) bending of the fascicle on the anterolateral edge of the talus with dorsiflexion and dorsiflexion-inversion, (4) is a distally inserting fascicle on the fibula, close to the origin of the ATFL on the fibula.
