Objective To explore the method and effectiveness of lateral calcaneal U-shaped incision approach to treat calcaneal fractures involving the talocalcaneal and calcaneocuboid joints. Methods Between January 2009 and March 2011, 36 cases of calcaneal fractures involving the talocalcaneal and calcaneocuboid joints were treated by the lateral calcaneal U-shaped incision approach and calcaneal anatomical plate fixation. There were 27 males and 9 females with an average age of 38.7 years (range, 19-58 years). According to the Sanders classification criteria, there were 12 cases of type II, 20 cases of type III, and 4 cases of type IV. The Bouml;hler and Gissane angles were (6.21 ± 10.48)° and (89.85 ± 12.34)°, respectively. The average time from injury to surgery was 4.2 days (range, 2-14 days). Results Superficial skin flap necrosis and wound exudate occurred in 1 case respectively, which were cured after dressing change; primary healing was obtained in the other cases. All the cases were followed up 12-26 months (mean, 15.2 months). The X-ray films showed that all fractures healed with an average healing time of 10.6 weeks (range, 8-12 weeks). The reduction of articular surface was satisfactory, and the heel height returned to normal. No complication of breakage of internal fixation or traumatic arthritis occurred. The Bouml;hler and Gissane angles were (29.64 ± 5.33)° and (121.75 ± 6.65)°, respectively at 3 months after operation, showing significant differences when compared with the preoperative values (t=43.800, P=0.000; t=33.200, P=0.000). The average time of plate removal was 11.2 months (range, 9-20 months). According to Maryland foot score, the results were excellent in 17 cases, good in 15 cases, and fair in 4 cases; the excellent and good rate was 88.9%. Conclusion The lateral calcaneal U-shaped incision approach is an effective method to treat calcaneal fractures involving the talocalcaneal and calcaneocuboid joints, which can expose the fracture fully, restore the anatomy of the calcaneal bone, and do early exercise under the condition of rigid internal fixation.
Objective To review the progress in the mechanism of injury, diagnosis, classification, and treatment method of Lisfranc injury. Methods Recent l iterature concerning the mechanism of injury, classification, diagnosis, and treatment method of Lisfranc injury was extensively reviewed, analyzed, and summarized. Results Because of the compl icate anatomy and high missed diagnosis rate, CT imaging were often recommended for diagnosis, and MRI could be used if necessary. The current recommendations for internal fixation included the use of Kirschner wires, cannulated screws, absorbablescrews, and plate. Conclusion Classification according to the columnar theory is significant for cl inical guiding. With thecl inical appl ication of internal fixation materials, more choices were provided, which make patients get the best effect.
ObjectiveTo summarize the effectiveness of mini locking plate combined with Kirschner wire in treatment of comminuted Jones fracture.MethodsBetween January 2011 and October 2016, 25 cases with comminuted Jones fracture were treated with mini locking plate combined with Kirschner wire. There were 9 males and 16 females with an average age of 31.4 years (range, 16-66 years). The fractures located on the left side in 11 cases and on the right side in 14 cases. The causes of injury included spraining in 21 cases, falling down in 3 cases, and bruise in 1 case. The bone fragment of all cases was more than 3 pieces. The fracture line was mostly Y-shape or T-shape. Twelve of them were combined with other fractures. The time from injury to operation was 1-9 days (mean, 5 days). The mini locking plate and Kirschner wire were removed at 9-12 months postoperatively. At 12 months postoperatively, the pain was evaluated by the visual analogue scale (VAS) score, and the function by the American Orthopaedic Foot & Ankle Society (AOFAS) score.ResultsAll incisions healed by first intention. All cases were followed up 12-36 months with an average of 21.7 months. Fracture union was observed in all patients without complications such as nonunion, delayed union, and malunion. The fracture union time was 8-12 weeks (mean, 9.4 weeks). At 12 months postoperatively, the VAS score was 1.15±0.87; the AOFAS score was 89.45±6.24, and the results were excellent in 14 cases, good in 9 cases, fair in 1 case, and poor in 1 case, with an excellent and good rate of 92%.ConclusionThe procedure of mini locking plate combined with Kirschner wire for comminuted Jones fracture has such advantages as convenient operation, more rigid fixation, high rate of fracture healing, and good functional recovery in foot.
Objective To investigate the treatment method and effectiveness of fresh closed fracture-dislocation of the midtarsal joint. Methods Between April 2004 and April 2011, 73 patients (75 feet) with fresh closed fracture-dislocation of the midtarsal joint were treated with closed reduction combined with open reduction and internal fixation. There were 56 males (58 feet) and 17 females (17 feet), aged from 19 to 62 years (mean, 35.8 years). Injuries were caused by falling from height in 35 cases, by sprain in 4 cases, by machine twist in 5 cases, by heavy pound in 9 cases, and by traffic accident in 20 cases. The time from injury to admission ranged from 1 hour and 30 minutes to 48 hours (mean, 4.5 hours). According to Main’s classification standard, 6 feet were rated as vertical compression injury, 33 feet as medial displacement injury, 17 feet as lateral displacement injury, 9 feet as flexion injury, and 10 feet as crush injury. Concomitant injuries included midfoot fracture-dislocation (34 feet), scaphoid fracture (6 feet), cuboid bone fracture (18 feet), calcaneal fracture (8 feet), talus fracture (7 feet), tibiotalar joint dislocation (2 feet), subtalar joint dislocation (2 feet), medial malleolus fracture (1 foot), and acute compartment syndrome (3 feet). Results Healing of incision by first intention was achieved in 65 cases (67 feet), by second intention in 8 cases (8 feet). Sixty-two cases (62 feet) were followed up from 11 months to 7 years and 11 months (mean, 3 years and 6 months). After operation, feet pain occurred in 26 cases, and stiffness or discomfort of the affected foot in 36 feet when walking. The X-ray examination showed good reduction of fracture-dislocation of the midtarsal joint and concomitant injuries with no re-dislocation or bone nonunion in 59 feet; 3 feet had flatfoot secondary to navicular necrosis, and underwent arthrodesis. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 77-90 (mean, 88.6) at last follow-up. Conclusion According to the preoperative evaluation of the damage, using the manual reduction combined with internal fixation (mini-plate or hollow screw with Kirschner wire) methods can obtain good effectiveness in the treatment of fracture-dislocation of the midtarsal joint.
Objective To analyse and summarize the diagnosis, treatment, and cl inical effects of talus lateral process fracture. Methods Between February 2001 and March 2009, 21 male patients with an average age of 33.6 years (range, 18-46years) with talus lateral process fractures were treated. Fracture was caused by fall ing from height in 18 cases, by tumbl ing in 2 cases, and by sprain in 1 case. According to Hawkins classification, there were 4 cases of type I, 15 cases of type II, and 2 cases of type III, all being closed fractures. The disease course was from 2 hours to 26 days. In 17 patients whose fracture fragments were more than 1 cm × 1 cm × 1 cm or whose fracture fragments shifting was more than 1 mm, open reduction and internal fixation with AO hollow titanium nails were performed in 14 patients, open reduction and internal fixation with door-shape self-made nail in 1 patient, and open reduction and internal fixation with absorbable screws in 2 patients. In 4 patients whose fracture fragments were less than 0.6 cm × 0.5 cm × 0.5 cm or whose fracture fragments shifting was less than 1 mm, fragments removel was performed in 2 patients, Kirschner pins in 1 patient, and plaster conservative therapy in 1 patient. In patients with l igaments injury, the l igaments was reconstructed during the operation. Results All the incisions achieved primary heal ing. Twenty-one patients were followed up 9.5 months to 8 years. No ankle pain occurred and the range of joint motion was normal after operation. The X-ray films showed that all cases achieved fracture union. And the healing time was from 8 weeks to 14 weeks (10 weeks on average). According toAmerican Orthopeadic Foot amp; Ankle Society (AOFAS) for foot, the results were excellent in 17 cases, good in 3 cases, and moderate in 1 case; the excellent and good rate was 95.24%. Conclusion The size and displacement of fracture fragment should be considered first in the treatment of lateral process fracture of talus; in patients who are compl icated by lateral malleolus l igament injury, the l igament should be reconstructed to avoid the chronic non-stabil ity of lateral ankle.
