Comparison of Surgical Outcomes for Lisfranc Joint Injuries:Dorsal Bridge Plating versus Transarticular Screw versus Combination

Purpose@#In Lisfranc joint injury, the traditional treatment has been open reduction and internal fixation with a transarticular screw. Despite this, additional complications, such as damage to the articular surface and breakage of the screw, have been reported. Therefore, this study compared the clinical and radiological outcomes of dorsal bridge plating with those of transarticular screws and combination treatment in Lisfranc joint injury. @*Materials and Methods@#Among the 43 patients who underwent surgical treatment due to Lisfranc joint injury from June 2015 to March 2021, 40 cases followed for more than six months after surgery were analyzed, excluding three patients: one lost to follow-up, one had to amputate, and one expired. The radiological parameters were measured using the Wilppula classification in the last follow-up. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score. @*Results@#The AOFAS midfoot score, according to the surgical method, was significantly higher in the dorsal bridge plating (p=0.003). The radiological outcomes showed significantly better anatomical reduction when dorsal bridge plating was used (p=0.040). According to the Wilppula classification, the AOFAS midfoot score improved as the quality of anatomical reduction improved (p=0.018). Finally, the AOFAS midfoot score decreased as the number of column fixations increased (p=0.002). There were two complications: screw breakage in dorsal bridge plating and superficial skin necrosis in the combination treatment. Skin defects caused by necrosis improved after negative pressure wound therapy and split-thickness skin graft. @*Conclusion@#In treating Lisfranc joint injuries, open reduction and internal fixation by dorsal bridge plating can be an appropriate treatment option. Nevertheless, studies, such as long-term follow-up research, on complications, such as osteoarthritis, will be needed.

Diagnosis and Management of Suspected Deltoid Injury / 대한족부족관절학회지

When an ankle lateral malleolar fracture is accompanied by a deltoid ligament rupture without a medial malleolar fracture, such an injury is called a bimalleolar equivalent fracture. This means that even if there is no bony injury on the medial side, there may be functional instability of the ankle joint due to damage to the deltoid ligament. Manual or gravity external rotational stress radiography is used to differentiate an ankle bimalleolar equivalent fracture from an isolated lateral malleolar fracture. If the medial joint gap is widened on the stress radiography, the deltoid ligament injury can be diagnosed, and surgical treatment for fibula fractures is recommended. After open reduction of the fibula fracture (with syndesmotic fixation if needed), a decision on the repair of the deltoid ligament is taken depending on the surgeons’ preference and intraoperative findings. The deltoid ligament repair is performed by inserting a suture anchor (or anchors) in the medial malleolus and fixing the deep and superficial deltoid ligaments to the medial malleolus. The only randomized study to evaluate the utility of deltoid ligament sutures in ankle fractures did not support the deltoid ligament suture, but the study itself had many limitations. An appropriately powered, randomized, controlled trial of the deltoid ligament repair with both patient-reported outcome and radiographic outcome evaluation is needed in the future.

Outcome of Extraarticular Dorsal Closing Wedge Osteotomy for Freiberg's Disease / 대한족부족관절학회지

PURPOSE: The aim of this study was to evaluate the result of extraarticular dorsal closing wedge osteotomy in Freiberg's disease. MATERIALS AND METHODS: Between February 2012 and July 2014, total 10 patients who underwent dorsal closing wedge osteotomy and followed up more than 1 year were selected for inclusion. Average age was 16.3 years, and average follow-up period was 15.5 months. The diagnosis was made using magnetic resonance imaging of those with a limitation in walking or usual activity due to pain in the metatarsal head. During operation, we removed loose body, and synovectomy was done. Osteotomy at the metatarsal neck and fixation with Kirschner wire were performed. X-ray was taken to check shortening of 2nd metatarsal and bone union. Moreover, we checked the active range of motion of 2nd metatarsophalangeal joint before and after surgery. At the last follow-up, the shortening of metatarsal, American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), and patient's subjective satisfaction were evaluated. RESULTS: According to the Smillie's stage, there were 3 cases of stage II, 4 cases of stage III, and 3 cases of stage IV. Average bone union time on the osteotomy site was 8 weeks. Average shortening of metatarsal was 2.53 mm. Average AOFAS score improved significantly from 56.9 to 82.8 points at final follow-up (p<0.05), and average VAS score also improved significantly from 6.4 to 1.4 points at final follow-up (p<0.05). Average active range of motion at metatarsophalangeal joint improved from 28.0° preoperatively to 46.5° at the final follow-up. Other complications, such as metatarsalgia and arthritis, were not found; however, there was 1 case of delayed union with no symptom. CONCLUSION: In Freiberg's disease, dorsal closing wedge osteotomy is recommended for the improvement of clinical symptoms and range of motion.

Analysis of Femoral Tunnel Position Targeted at Bifurcate Ridge Using Anteromedial Portal Technique in Anatomic Anterior Cruciate Ligament Reconstruction / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to analyze the position of the 10-mm-sized femur tunnel drilled aiming for the bifurcate ridge using anteromedial portal technique with 'Figure of 4 position' by 3-dimensional computed tomography (3D-CT) reconstruction images after anatomic anterior cruciate ligament (ACL) reconstruction and to evaluate it's propriety. MATERIALS AND METHODS: Out of 35 patients who underwent anatomic ACL reconstruction from March 2012 to February 2013, 32 patients who undergone postoperative 3D-CT scans were included in this study retrospectively. Medial surface of the lateral femoral condyle was reconstructed using Mimics, and then the position of the femoral tunnel was evaluated using the Bernard quadrant method and the results were compared with those of published literatures. The mean age of the patients was 32.6 years old. There were 25 cases of double-bundle ACL reconstruction with one femoral-two tibial tunnel. There were 7 cases of single bundle ACL reconstruction with one femoral-one tibial tunnel. RESULTS: The mean distance of the femoral tunnel center was 32.2%+/-2.9% (range, 27.4%-37.6%) along the line parallel to the Blumensaat's line from the posterior condylar surface and 46.7%+/-2.3% (range, 43.5%-51.1%) along the line perpendicular to the Blumensaat's line from the roof of the notch. In comparison with the results of published literature, although the center of the femoral tunnel was presented in the femoral footprint, it was located slightly more shallow and inferior than the center of the ACL footprints. CONCLUSION: The bifurcate ridge may be a good anatomic landmark when making a 10-mm-sized single femoral tunnel in 'Figure of 4 position' using the anteromedial portal technique.
