ObjectiveTo study the surgical treatment method and effectiveness of Rüedi-Allg?wer Ⅲ type Pilon fractures.
MethodsBetween May 2011 and April 2013,25 cases of Rüedi-Allg?wer Ⅲ type Pilon fracture (5 cases of open fractures and 20 cases of closed fractures) were treated.Of 25 cases,16 were male,and 9 were female,aged 24-45 years (mean,31 years).The left side was involved in 8 cases,and the right side in 17 cases.The disease causes were falling from height in 11 cases,traffic accident injury in 9 cases,and crash injury in 5 cases.The interval of injury and admission was 10-36 hours (mean,23.5 hours).The open reduction and internal fixation by posterolateral fibular incision and exposure of distal tibia and tibiotalar articular surface by anterior ankle incision were performed;the tibiotalar articular surface was reset and the tibia fracture end was fixed.
ResultsHealing of incision by first intention was obtained in 15 cases,and healing by second intention in 6 cases undergoing skin grafting.Tension blister occurred in 4 patients,who achieved healing by second intention after treatment.All 25 patients were followed up 6-12 months (mean,8 months).During follow-up,no complication of ankle joint instability,traumatic arthritis,or loosening and breakage of internal fixation occurred.The X-ray films showed stable ankle joint,anatomic or near anatomic reduction of the tibiotalar articular surface,normal alignment of distal tibia,and good bony healing.At 6 to 12 months after operation,the flexion and extension of the ankle were normal,without pain of the ankle joint after removal of internal fixation.According to Mazur et al.rating system for ankle symptoms and function,the results were excellent in 5 cases,good in 12 cases,fair in 5 cases,and poor in 3 cases;the excellent and good rate was 68%.
ConclusionThe procedure by anterior ankle lateral approach and posterolateral fibular approach can completely expose the tibiotalar articular surface,which is advantageous to displaced fracture reduction and fixation,and can achieve good effectiveness in treating Rüedi-Allg?wer Ⅲ type Pilon fractures.
Objective To summarize the effect and complication of treatment for Pilon fracture using limited internal fixation combined with external fixation. Methods From April 1996 to June 2003, 20 patients with Pilon fracture were treated with limited internal fixation combined with external fixation as the treatment group and 22 patients with Pilon fracture with other methods as the control group. The X-ray films, clinical effect and complication were analyzed and compared between 2 groups. Results All cases were followed up for 8 to 26 months(15.2 months on average). According to Helfet’s criterion forclinical effect, the excellent and good rates were 75% in the treatment group and 72.7%in the control group, being no significant difference (Pgt;0.05). According to Burwell-charnley criterion for reduction, the X-ray film resultsshowed the excellent and good rates were 90% in the treatment group and 86.4% in the control group, being no significant difference (Pgt;0.05). But there was significant difference in complications between 2 groups (Plt;0.05). Conclusion Limited internal fixation combined with external fixation is better in resuming ankle joint function and remarkably reducing complication, especially in reducing soft tissue complication and collapse of bone joint; it is useful in the treatment of Pilon fracture.
Objective To explore an improved method of surgical operation for reposition of the articular surface with Type Ⅲ Pilon fractures. Methods From January 1999 to December 2005, 20 patients (22 sides) with Type Ⅲ Pilon fractures were treated with the delayed open reduction and the internal fixation, which took the superior articular surface of the talus as a templet so as to reposition the lower articular surface of the tibia, strengthen the bone transplantation, fasten the internal fixation, and make an early functional exercise possible. Complete data were obtained from 16 of the patients with 18 sides (13 males,15 sides; 3 females, 3 sides; age, 14-48 years). The injury due to a fallingaccident was found in 12 patients (14 sides), and due to a traffic accident in 4patients (4 sides). Results The healing of the first intention was achieved in 14 sides, the delayed healing in 3 sides, and the infection in 1 side. The follow-up of all the 16 patients for 971 months (average, 22 months) including the X-ray examinations revealed that no screw for the internal fixation entering the articular cavity. According to the Teeny’s judging standards of radiology evaluating the result of the surgery for Pilon fractures, the anatomical reduction of the related articular surface was found in 77.8% of the sides (14/18) and thehealing of the first intention (stage Ⅰ) in 94.4% (17/18). According to the Mazur’s criteria, an excellent result was obtained in 5 sides, good in 7, fair in 5, and poor in 1. The excellent and good result was 66.7%. Conclusion Propermanagement of the injured soft tissues, prompt recovery of the tibial distant plateau height, and accurate reposition of the articular surface, enough transplant bone for the solid support, b internal fixation for the distant tibial anatomical structure, and early functional exercise are the key points to the successful operation.
ObjectiveTo analyze the importance and effectiveness of Tillaux bone block in Ruedi-Allgower type Ⅲ of Pilon fracture surgery.MethodsTwenty-one patients with Pilon fractures with Tillaux dislocation were treated between February 2010 and September 2013. There were 17 males and 4 females, aged from 28 to 68 years with an average age of 42.9 years. The causes of injury included falling from height in 13 cases, falls injury in 4 cases, crush injury in 2 cases, and sprained injury in 2 cases. X-ray film and CT examination showed that all 21 patients had fibula fracture and Tillaux bone block had obvious displacement. According to AO/OTA classification, there were 3 cases of type C1.2, 1 case of type C1.3, 10 cases of type C2, and 7 cases of type C3. The duration from injury to operation ranged from 4 to 31 days, with an average of 10 days. All cases of Pilon fracture were treated with open reduction and plate internal fixation. Steel plate or screw was used to fixation for Tillaux block; allograft bone graft was selected for compression of fracture.ResultsThere were 2 cases of skin necrosis at the corner of wound after operation, and the wound healed after corresponding treatment; the wound healed at first intention in the other 19 cases. The effect of surgical reduction was evaluated by Burwell-Chamley imaging scoring system within 72 hours after operation, there were 19 cases of anatomical reduction and 2 cases of general reduction. All the 21 patients were followed up 18-48 months, with an average of 24.9 months. No complication such as nerve injury, loosening of internal fixation, or periprosthetic fracture was found during follow-up. All fractures obtained bone healing, which lasted from 4 to 8 months, with an average of 6 months. The ankle and hindfoot scores of the American Orthopaedic Foot and Ankle Society (AOFAS) were used to evaluate the ankle and hindfoot function at 1 year after operation or at last follow-up, the results were excellent in 13 cases, good in 6 cases, and fair in 2 cases, with an excellent and good rate of 90.5%. Internal fixator was removed from 19 patients at 15-19 months after operation. There were 17 cases of joint hyperplasia and 4 cases of osteoarthritis. All joint mobility was restored. The functional recovery of the ankle joint was evaluated according to the Olerud-Molander ankle fracture score standard, the results were good in 6 cases, fair in 8 cases, and poor in 7 cases at postoperative full weight training; and after 1 year of full weight training, the results were excellent in 10 cases, good in 3 cases, fair in 6 cases, and poor in 2 cases.ConclusionThe Tillaux bone block is a reliable marker for the reduction of complex Pilon fractures. The reconstruction of the Tillaux can improve the effectiveness of complex Pilon fractures.
Objective To explore an improved method of surgical operation for redintegration of the articular surface and alignment with type III Pilon fractures. Methods Between August 2005 and August 2010, 31 patiens with closed type III Pilon fracture (Rüedi-Allgouml;wer type III) were treated. There were 25 males and 6 females, aged 36.8 years on average (range, 16-60 years). The injury was caused by falling from height in 18 patients, by traffic accident in 10 patients, and by other reasons in 3 patients. The average time between injury and operation was 10 days (range, 6-14 days). Temporary external fixation was used for adjustment and maintenance of limb length and power lines; application of fibular flip combined with anteromedial approach was used for the repair of articular surface; and bone grafting and fixation were performed. Results No extensive necrosis or deep infection were observed. Superficial skin infection of incision and wound edge necrosis occurred in 2 cases respectively, and were cured after dressing change. All patients were followed up 26 months on average (range, 9-79 months). According to the Burwell et al. judging standards of radiology evaluating, the anatomical reduction was found in 25 cases (80.6%), satisfactory reduction in 4 cases (12.9%), and unsatisfactory reduction in 2 cases (6.5%). The X-ray films showed bony healing was achieved in all cases with an average fracture healing time of 16 weeks (range, 12-25 weeks). According to the Mazur et al. criterion for ankle joint function, excellent result was obtained in 11 cases, good in 13, fair in 5, and poor in 2; the excellent and good rate was 77.4%. Conclusion Good exposure and fixation of articular surface or accurate adjustments and maintenance of the limb alignment are key factors of successful operation to treat type III Pilon fractures.
Objective
To explore the effectiveness of staged treatment of open Pilon fracture combined with soft tissue defect.
Methods
Between June 2007 and December 2012, 18 cases of open Pilon fracture combined with soft tissue defect were treated. There were 14 males and 4 females with an average age of 35 years (range, 19-55 years). The causes of injury included falling from height in 12 cases, traffic accident in 4 cases, and crushing by machine in 2 cases. According to AO classification, 1 case was classified as type B2 fracture, 3 cases as type B3 fracture, 5 cases as type C1 fracture, 5 cases as type C2 fracture, and 4 cases as type C3 fracture. Sixteen cases accompanied by fibular fracture (14 cases of simple fibular fracture and 2 cases of communicated fibular fracture). According to Gustilo classification, the soft tissue injuries were all type IIIB. In first stage, debridement and vaccum sealing drainage combined with external fixation were performed; open reduction and internal fixation of simple fibular fracture were used. In second stage, open reduction and internal fixation of Pilon fracture and communicated fibular fracture were performed, and the flaps of 6 cm × 5 cm to 18 cm × 14 cm were applied to repair soft tissue defect at the same time. The donor site was repaired by skin graft.
Results
Partial necrosis occurred in 2 flaps, the other 16 flaps survived completely. The incisions of donor sites healed by first intention, the skin graft survived completely. The average follow-up interval was 12 months (range, 6-24 months). The X-ray films showed that the bone healing time ranged from 5 to 8 months (mean, 6 months). No internal fixation failure was found. At last follow-up, the average range of motion of the ankle joint was 37° (range, 26-57°). According to the American Orthopedic Foot and Ankle Society (AOFAS) scale, the average score was 80.2 (range, 72-86). Traumatic arthritis occurred in 2 cases (11%).
Conclusion
The staged treatment has the advantages of accurate evaluation of soft tissue injury, shortened cure time, good reduction of the articular surface, and reduced incidence of infection, so it is an optimal method to treat open Pilon fracture combined with soft tissue defect.
ObjectiveTo investigate the clinical effect of surgical treatment of Pilon fractures accompanied with fibula fractures with the improved double operative approaches.
MethodsBetween January 2012 and June 2015, 19 patients with closed Pilon fractures accompanied with fibula fractures (Rüedi-Allg?wer type Ⅲ) underwent open reduction and internal fixation with improved anterior-median incision and posterior-lateral incision. There were 13 males and 6 females, aged 35 years on average (range, 23-68 years). Injury was caused by traffic accident in 11 cases, falling from height in 7 cases, and crash injury of heavy object in 1 case. According to AO/OTA classification, there were 4 cases of type C2, and 15 cases of type C3. According to Tscherne-Gotzen classification of soft tissue defect, 6 cases were rated as grade 1 and 13 cases as grade 2. The interval of injury and operation was 6-18 days (mean, 10.3 days). After operation, reduction of Pilon fracture was evaluated by the Burwell-Charnley radiological evaluation criteria, and the ankle joint function was evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.
ResultsThe operation time was 1.8-4.6 hours (mean, 2.4 hours); the intraoperative blood loss was 200-500 mL (mean, 310 mL). All the 19 patients were followed up for 13.7 months on average (range, 12-18 months). The fracture healing time was 3.6 months on average (range, 2.5-8.0 months). Postoperative complications included anterior-median incision necrosis in 2 cases, traumatic arthritis in 2 cases, and ankle instability in 1 case. According to Burwell-Charnley radiological evaluation criteria, anatomical reduction was obtained in 15 cases and satisfactory reduction in 4 cases. According to AOFAS score, the excellent and good rate was 84.2% (excellent in 11 cases, good in 5 cases, and fair in 3 cases).
ConclusionThe improved anterior-median incision combined with posterior-lateral incision is a safe and effective method to treat complex Pilon fractures accompanied with fibula fractures, which has the advantages of simple operation, adequate exposure and minimal invasion.
Pilon fracture is one of the most common and complex fractures in clinic. It has many postoperative complications, such as limitation of motion, pain, swelling, and decreased muscle strength. Complications will seriously affect patients’ ankle function. If the accelerated rehabilitation support can be obtained, patients can obtain a good functional recovery in the later stage. At present, there are few reports on enhanced rehabilitation related to Pilon fractures. This article introduces the rehabilitation treatment protocol for perioperative accelerated rehabilitation of Pilon fractures, mainly including rehabilitation evaluation, preoperative rehabilitation and postoperative rehabilitation treatment, aiming to provide some reference for standardizing the rehabilitation treatment of Pilon fractures in the perioperative period.
ObjectiveTo investigate the safety, feasibility, and effectiveness of modified staging strategy in treatment of type C3 Pilon fractures.MethodsThe clinical data of 23 patients with type C3 Pilon fractures treated with modified staging strategy between January 2012 and January 2018 was retrospectively analyzed. There were 14 males and 9 females with an average age of 47.9 years (range, 22-61 years). Twenty-three cases were high-energy injuries, including 11 cases of traffic accidents and 12 cases of falling from height. One case was an open fracture of Gustilo type ⅢA with no obvious sign of infection on the wound after early treatment. The remaining patients were closed fractures. The time from injury to admission was 3-40 hours with an average of 16.4 hours. The preoperative pain visual analogue scale (VAS) score was 7.22±1.17 and American Orthopaedic Foot and Ankle Society (AOFAS) score was 0. The flexion and plantar flexion activities of ankle joint were (1.13±0.26) and (4.79±0.93)°, respectively. Twenty-two patients had a tibiofibular fracture. In the first-stage operation, the posterior approach was used to reduce the posterior column fracture and the external stent was temporarily assisted. After the soft tissue crisis was removed, the final fracture reduction and internal fixation was performed through the anterior approach in the second-stage operation.ResultsAll 23 patients were followed up 12-84 months with an average of 26.6 months. The waiting time before the first-stage operation was 4-47 hours with an average of 23.4 hours. The interval between the two stage operations was 6-11 days with an average of 7.9 days. The first-stage operation time was 60-90 minutes with an average of 67.8 minutes; the second-stage operation time was 110-160 minutes with an average of 124.1 minutes. The hospital stay was 15-28 days with an average of 23.5 days. One patient (4.35%) had a tourniquet paralysis symptom after the second-stage operation, and two patients (8.7%) had delayed anterior incision healing. The other patients had incision healing without early complications. The radiographic review showed that the quality of articular surface reduction was excellent in 19 cases, good in 2 cases, and poor in 2 cases, with an excellent and good rate of 91.3%. At last follow-up, the fractures healed with no bone nonunion and malunion; the different degrees of osteoarthritis occurred in 7 cases. At last follow-up, the VAS score was 0.89 ±0.88 and the AOFAS score was 81.3±7.8. The flexion and plantar flexion activities of ankle joint were (10.23±5.05) and (20.97±3.92)°, respectively, and the differences between pre- and post-operation were significant (P<0.05).ConclusionThe midified staging strategy can not only provide a template for articular surface reduction for the second-stage anterior surgery, but also improve the quality of the reduction. It can also reduce the interval between the two operations and the operation time of the second-stage operation through the first-stage posterior fascial decompression, and can obtain satisfactory effectiveness.
ObjectiveTo evaluate the effectiveness of very low profile/variable angle locking plate (VLP) internal fixation for posterior Pilon fractures extending to the medial malleolus by posteromedial approach.
MethodsA retrospective analysis was made on the clinical data from 13 patients with posterior Pilon fractures extending to the medial malleolus between December 2011 and August 2012. There were 4 males and 9 females with an average age of 48.9 years (range, 23-68 years). Fractures were caused by falling in 9 cases and by traffic accident in 4 cases. The locations were the left ankle in 6 cases and the right ankle in 7 cases. According to the Orthopedic Trauma Association (OTA) classification, 6 cases were rated as type 43B1, 4 cases as type 43B2, and 3 cases as type 43B3. Twelve cases had fibular fractures, including 11 cases of Denis-Weber type B, 1 case of Denis-Weber type C. The interval of injury and operation was 7-14 days (mean, 11.4 days). Open reduction was performed and VLP internal fixation was used for posterior malleolar fracture by posteromedial approach.
ResultsPrimary healing of incision was obtained in all patients. Tibial nerve palsy was observed in 2 cases, and was cured after oral administration of mecobalamin. Twelve cases were followed up 12-18 months (mean, 14.5 months). According to the Burwell-Charnley's radiological evaluation system, 11 cases achieved anatomical reduction, 1 case achieved fair reduction. The fracture union time was 3-6 months (mean, 3.7 months). No loosening or breakage of internal fixation occurred during follow-up. According to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, the results were excellent in 7 cases, good in 4, and fair in 1; the excellent and good rate was 91.7%.
ConclusionVLP internal fixation for posterior Pilon fractures extending to the medial malleolus by posteromedial approach can achieve good short-term effectiveness. The high quality of reduction is acquired under direct vision with low rate of soft tissue complications.
