  • ARTHROSCOPICAL SUBTALAR ARTHRODESIS FOR MALUNION OF CALCANEAL FRACTURES

    Objective To evaluate the cl inical results of arthroscopical subtalar arthrodesis for malunion of calcaneal fractures. Methods Between July 2006 and December 2008, 12 cases of malunion of calcaneal fractures were treated witharthroscopical subtalar arthrodesis, inculding 10 males and 2 females with an age range of 38-54 years (44.8 years on average). The location was left side in 5 cases and right side in 7 cases. The injury was caused by fall ing from height in 8 cases, by traffic accident in 3 cases, and other in 1 case. It was 3-7 months from injury to operation. All cases were classified as Stephens type II. The total score was 35.68 ± 10.35 and the pain score was 8.14 ± 1.83 before operation according to Hindfoot scores system of American Orthopaedic Foot amp; Ankle Society (AOFAS). Results All incisions achieved parimary heal ing and the patients were all followed up 14-32 months (18 months on average). The X-ray films showed bony fusion after 10-14 weeks (11.5 weeks on average). The total score was 76.45 ± 9.83 and the pain score was 1.52 ± 1.48 after operation according to Hindfoot scores system of AOFAS, showing significant difference when compared with those before operation (P lt; 0.01). Conclusion Arthroscopical subtalar arthrodesis can get satisfactory fusion rate with few compl ications for malunion of calcaneal fractures.

  • RECONSTRUCTION OF MALUNITED FRACTURE OF TIBIAL PLATEAU

    Objective To explore the treatment of the malunited fracture of the tibial plateau. Methods From June 2000 to June 2005, reconstruction was performed on 29 patients (18 males, 11 females; age, 1943 years, average, 31.6 years) with the malunited fracture of the tibial plateau. The injury duration ranged from 2.5 months to 2 years, averaged 9.7 months. After the injury, the plasterexternal fixation was performed on 8 patients and operation was performed on the other 21 patients. The operation was involved in the use of screws in 11 patients, anatomic plates, Golf plates and allotype plates in 8 patients, external fixation braces in 2 patients. A complicating injury to the anterior cruciate ligament (ACL) was found in 4 patients, an injury to the posterior cruciate ligament(PCL) in 2 patients, an injury to both ACL and PCL in 1 patient, and an injury to the meniscus in 6 patients. Reestablishment was performed on 19 patients, high tibial osteotomy on 7 patients, and osteotomy of the half tibial metaphysis on3 patients. Results Base on the followup for 8 months to 3 years(average, 13.6 months), the comprehensively scoring assessment showed that an excellent result was achieved in 8 patients, good in 15, fair in 4, and poor in 1, with an excellent and good rate of 82.1%, according to the Hohl knee joint function assessment on the pain, active movement, motion range, stability, and selfassessment. ConclusionFor the reconstruction of the malunited fracture of the tibial plateau, the satisfactory therapeutic effectiveness can only be achieved if the proper indications are identified and the suitable operative methods are adopted.

  • TREATMENT OF OLD UNITED LATERAL CONDYLE FRACTURES OF HUMERUS IN CHILDREN

    Objective To analyze the treatment of old united lateral condyle fractures of humerus in children.Methods From January 1997 toFebruary 2002, 13 cases of old united lateral condyle fractures of humerus were treated. There were 11 boys and 2 girls. Their age was from 4 to 11 years(7.2 years on average). The primary diagnosis results were 4 cases of degree Ⅰ fracture, 5 cases of degree Ⅱ fracture and 4 indefinitely diagnosed cases. Elbow extension disorder occurred in 13 cases, which was limited 30-70°. The elbow flexion was limited morethan 90°. X-ray films showed 10 nonunion and 3 malunion of fracture. The timefrominjury to operation was 32 to 81 days (56 days on average) in 12 cases and6 months in 1 case. All cases were treated by open reduction and internal fixation. One case was treated combined with implanting bone. Results After a follow-up of 3 to 8 years(5.4 years on average), no cubitus varus or valgus occurred.Five cases had growth disturbances of the lateral condyle of the distal humerus. The movement of these elbow joints improved from 40° to 70° (56° on average). The time of clinical bone union was 6 to 8 weeks and no nonunion and delayed union were observed in X-ray films. Conclusion It is important to accurately diagnose for treatment of lateral condyle fractures of the humerus in children so as to reduce the occurrence of malunion of fracture. It can save the joint function and reduce the cosmetic deformity effectively to operate as earlyas possible.

  • SUBTALAR ARTHRODESIS AND CALCANEAL THALAMUS RECONSTRUCTION FOR MALUNION OF CALCANEAL FRACTURES

    Objective To evaluate the clinical results of subtalar arthrodesis and calcaneal thalamus reconstruction for malunion of calcaneal fractures and to discuss the indications and its advantages of the management. Methods From December 1994 to January 2006, 84 cases(96 feet) of malunion of calcaneal fractures were treated with subtalar arthrodesis and calcaneal thalamus reconstruction. The L-shaped approach lateral to calcaneus was used. The bone autograft was harvested from iliac crest. Fiftyone cases were male and 33 cases were female, aging from 21 to 58 years (mean 385 years).One side was in volved in 72 cases and two sides in 12 cases. The injury was caused by falling from height in 57 cases, by traffic accident in 22 cases and other in 5 cases. It was 6-31 months from injury to operation (mean 9.5 months). Results Among the patients, all cases were followed up 1 to 132 months. The total excellent and good rate was 87.5%, including excellent in 31 feet, good in 53 feet and fair in 12 feet,according to Hindfoot scores system (American Orthopaedics Foot and Ankle Society). The B[AKo¨]hler’s and Gissane’s angles, the height of calcaneal thalamus and width of calcaneus were significant different from those of preoperation (Plt;0.01). Conclusion The treatment by bone autograft combined with subtalar arthrodesis and calcaneal thalamus reconstruction is an effective operation for malunion of calcaneal fractures, with advantages of correcting deformity, restoring the function of indfoot and relieving the pain of walking.

  • Application and research progress of subtalar distraction bone block arthrodesis in treatment of calcaneus fracture malunion

    Objective To review the application and research progress of subtalar distraction bone block arth-rodesis in the treatment of calcaneus fracture malunion. Methods The recent literature concerning the history, surgical technique, postoperative complication, indications, and curative effect of subtalar distraction arthrodesis with bone graft block interposition in the treatment of calcaneus fracture malunion was summarized and analyzed. Results Subtalar distraction bone block arthrodesis is one of the main ways to treat calcaneus fracture malunion, including a combined surgery with subtalar arthrodesis and realignment surgery for hindfoot deformity using bone block graft. The advantage is on the base of subtalar joint fusion, through one-time retracting subtalar joint, the posterior articular surface of subtalar joint implants bone block can partially restore calcaneal height, thus improving the function of the foot. Compared with other calcaneal malunion treatments, subtalar distraction arthrodesis is effective to correct complications caused by calcaneus fracture malunion, and it can restore the height of talus and calcaneus, correct loss of talocalcaneal angle, and ease pain. Conclusion Subtalar distraction bone block arthrodesis has made remarkable progress in the treatment of calcaneus fracture malunion, but it has the disadvantages of postoperative nonunion and absorption of bone block, so further study is needed.

  • Outcome of corrective osteotomy of shortened medial foot column after old talar neck fracture

    ObjectiveTo investigate the effectiveness of corrective osteotomy for shortened medial foot column after old talar neck fracture.MethodsThe clinical data of 10 patients with shortened medial foot column after old talar neck fracture between June 2012 and May 2017 was retrospectively analyzed. There were 7 males and 3 females with an average age of 45.8 years (mean, 21-67 years). The time from fracture to corrective osteotomy was 9-60 months (mean, 20.9 months). The preoperative visual analogue scale (VAS) score was 7.1±1.2, the American Orthopaedic Foot and Ankle Society (AOFAS) score was 48.5±12.3, and the short-form 36 health survey scale (SF-36) score was 46.7±10.5. All 10 cases received open wedge osteotomy of medial talus. Among them, 2 received subtalar fusion and Achilles tendon lengthening, 2 lateralizing calcaneal osteotomy, and 2 Achilles tendon lengthening.ResultsAll incisions healed by first intention. All patients were followed up 13-72 months (mean, 38.0 months). The X-ray film showed that the angle between longitudinal axis of 1st metatarsal bone and talus increased from (−9.6±4.5) ° before operation to (1.3±2.7) ° at last follow-up (t=16.717, P=0.000); the angle between longitudinal axis of calcaneus and tibia increased from (−12.0±7.4) ° before operation to (−1.5±4.8) ° at last follow-up (t=5.711, P=0.000). At last follow-up, the VAS score, AOFAS score, and SF-36 score were 1.6±1.0, 88.3±5.4, and 85.4±9.2, respectively, which increased significantly when compared with the preoperative scores (t=13.703, P=0.000; t=14.883, P=0.000; t=16.919, P=0.000). X-ray film and CT showed that the osteotomy and arthrodesis sites healed well at 2-4 months after operation.ConclusionIt’s a proper procedure of anatomic reduction and reconstruction for patients with shortened medial foot column and good articular cartilage morphology after old talar fracture. Opening wedge osteotomy of medial talus is recommended and can obtain satisfactory clinical and radiographic results.

  • Calcaneal V-shaped osteotomy combined with subtalar arthrodesis for Stephens Ⅱ and Ⅲ calcaneal fractures malunion

    Objective To investigate the effectiveness of calcaneal V-shaped osteotomy combined with subtalar arthrodesis in the treatment of Stephens Ⅱand Ⅲ calcaneal fracture malunion. MethodsThe clinical data of 24 patients with severe calcaneal fracture malunion treated by calcaneal V-shaped osteotomy combined with subtalar arthrodesis between January 2017 and December 2021 were retrospectively analyzed. There were 20 males and 4 females with an average age of 42.8 years (range, 33-60 years). Conservative treatment of calcaneal fracture failed in 19 cases and operation failed in 5 cases. Stephens classification of calcaneal fracture malunion was type Ⅱ in 14 cases, and type Ⅲ in 10 cases. Preoperative Böhler angle of calcaneus was 4.0°-13.5° (mean, 8.6°), Gissane angle was 100°-152° (mean, 119.3°). The time from injury to operation was 6-14 months (mean, 9.7 months). American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analogue scale (VAS) score were used to evaluate the effectiveness before operation and at last follow-up. Bone healing was observed and the healing time was recorded. The talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were measured. Results Necrosis of the cuticle edge of the incision occurred in 3 cases, which were cured by dressing change and oral administration of antibiotic therapy. The other incisions healed by first intention. All the 24 patients were followed up 12-23 months, with an average of 17.1 months. The foot shape of the patients recovered well, the shoes were restored to the size before injury, and there was no anterior ankle impingement. Bone union was achieved in all patients, and the healing time ranged from 12 to 18 weeks, with an average of 14.1 weeks. At last follow-up, no adjacent joint degeneration occurred in all patients; 5 patients had mild foot pain during walking, which had no significant impact on daily life and work; no patient needed revision surgery. The AOFAS ankle and hindfoot score was significantly higher than that before operation (P<0.001), the results were excellent in 16 cases, good in 4 cases, and poor in 4 cases, and the excellent and good rate was 83.3%. The VAS score, talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were significantly improved after operation (P<0.001). ConclusionCalcaneal V-shaped osteotomy combined with subtalar arthrodesis can effectively relieve hindfoot pain, correct talocalcaneal height, restore talus inclination angle, and reduce the risk of nonunion after subtalar arthrodesis.
