ABSTRACT
OBJECTIVE@#To evaluate the early effectiveness of a new minimally invasive plate in the treatment of varus-type ankle arthritis.@*METHODS@#A clinical data of 15 patients with varus-type ankle arthritis who met the selection criteria between March 2021 and October 2021 were retrospectively analyzed. All the patients were treated with medial open-wedge supramalleolar osteotomy and fibular osteotomy. The osteotomies were fixed with the new minimally invasive plate. There were 7 males and 8 females with an average age of 49.8 years (range, 16-71 years). The causes of ankle arthritis included post-fracture deformity in 1 case, sprain in 8 cases, and acquired clubfoot in 1 case; and 5 cases were without obvious factors. The disease duration ranged from 1 to 12 years, with an average of 4.1 years. Comparisons were made between pre-operation and the last follow-up in the Takakura staging, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, foot function index (FFI), visual analogue scale (VAS) score, tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).@*RESULTS@#All incisions healed by first intention. All patients were followed up 7-18 months (mean, 12.8 months). At last follow-up, the AOFAS ankle-hindfoot score, FFI, VAS score, and Takakura staging significantly improved when compared with the preoperative ones ( P<0.05). X-ray films showed that the osteotomy healed at 3 months after operation. At last follow-up, TAS significantly increased and TT decreased when compared with the preoperative ones ( P<0.05), and the difference in TLS between pre- and post-operation was not significant ( P>0.05). Complications included 1 case of intraoperative screw breakage and 2 cases of nerve injury of the affected foot. None of the patients complained of significant discomfort at the plate placement during follow-up, and no loosening of the internal fixator occurred. Eleven patients were very satisfied with the effeectiveness, while 4 were relatively satisfied.@*CONCLUSION@#The new minimally invasive plate for the varus-type ankle arthritis has good early effectiveness in relieving ankle pain, correcting deformity, improving limb alignment and ankle function, and reducing the incidence of postoperative incisional complications.

Objective:To evaluate the clinical and radiographic outcomes of tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach.Methods:From March 2018 to February 2021, 23 patients underwent tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach at the Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital.Of them, 15 were males and 8 females. Their average age at surgery was 54.4 years (range, from 28 to 72 years). There were 11 cases of traumatic arthritis, 2 cases of Charcot arthropathy, 6 cases of neurogenic equinovarus, 2 cases of traumatic equinovarus, and 2 cases of Kashin-Beck disease. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), visual analogue scale (VAS), foot function index (FFI), hindfoot alignment angle (HA), hindfoot alignment distance (HD), and hindfoot alignment ratio (HR). The tibia-foot angle on lateral weight-bearing and patient satisfaction at the last follow-up and postoperative complications were documented.Results:This cohort were followed up for an average of 24.7 months (from 12 to 48 months). The AOFAS ankle-hindfoot score (78.2 ± 9.2), VAS [2.0 (0.5, 2.0)], FFI [19.0 (10.5, 35.0)], HA (2.7° ± 5.8°), HD [(0.1 ± 0.8) cm] and HR [44.2 (36.4, 59.2)%] at the last follow-up were significantly improved than the preoperative values [43.4 ± 12.7, 4.0 (4.0, 6.0), 98.0 (60.0, 127.0), 22.0° ± 14.3°, (2.2 ± 1.6) cm and 86.0 (66.3, 100.0)%] (all P<0.05). The tibia-foot angle on lateral weight-bearing was 89.0° (87.1°, 90.4°) at the last follow-up. By the Likert scale, 17 cases were very satisfied with the surgery, 4 cases satisfied and 2 cases tolerate, giving a satisfaction rate of 91.3%(21/23). Infection occurred in one case and nonunion in one. Conclusion:Tibiotalocalcaneal arthrodesis via the fibula-preserving anterolateral approach yields good mid- to short-term clinical and radiographic outcomes, showing a strong capability to correct ankle and hindfoot varus and equinus.
ABSTRACT
Objective:To report our clinical outcomes of open reduction and internal fixation (ORIF) of chronic isolated fractures of a metatarsal head in the lesser toes.Methods:A retrospective consecutive case-series study was performed in 5 patients with symptomatic chronic isolated shear fracture of a metatarsal head in the lesser toes who had been treated from January 2018 to April 2021 at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. There were 4 males and one female, with an average age of 26.2 years (from 19 to 36 years) at the time of injury. The fracture had been missed at the initial diagnosis in 2 of the patients. Their main symptom was limited dorsiflexion of the metatarsophalangeal joint (MTPJ). Preoperative X-rays and CT scans revealed dorsal displacement of the distal fragment without dislocation of the MTPJ. All patients were treated by ORIF. Their American Orthopaedic Foot & Ankle Society-lesser metatarsophalangeal-interphalangeal (AOFAS-LMI) score, visual analog scale (VAS), and range of passive dorsiflexion of the MTPJ were compared between preoperation and the final follow-up. Postoperative complications were also recorded.Results:The 5 patients were followed up for an average of 27.8 months (from 6 to 45 months). All the chronic fractures achieved bony union. At the final follow-up, the average AOFAS-LMI score was 90.6 (from 82 to 100), the average VAS score 0 (from 0 to 2), and the average range of passive dorsiflexion of the MTPJ 40.0° (from 35° to 45°), all improved compared with the preoperative values [70.6 (from 59 to 79), 4 (from 2 to 5) and 10.0° (from 5.0° to 10.0°), respectively]. All the patients recovered their activity levels before injury. Three patients developed arthritis of the MTPJ.Conclusion:ORIF may achieve good short- and mid-term clinical outcomes in patients with chronic isolated shear fracture of a metatarsal head in the lesser toes.
ABSTRACT
Objective:To evaluate the radiologic and clinical outcomes of supramalleolar dome osteotomy in the treatment of varus-type ankle arthritis.Methods:From June 2018 to December 2019, 13 patients with varus-type ankle arthritis underwent supramalleolar dome osteotomy at Department of Foot and Ankle Surgery, Beijing Jishuitan Hospital. Of them, 13 (5 males and 8 females) were included in the study. Their average age at surgery was 47.2 years (range, from 16 to 65 years). By the modified Takakura staging for arthritis, 3 cases were stage 2, 4 cases stage 3a and 6 cases stage 3b. Comparisons were made between preoperation and the last follow-up in ankle-hindfoot score of American Orthopedic Foot and Ankle Society (AOFAS), foot function index (FFI), visual analogue scale (VAS), Takakura staging, dorsal extension, plantar flexion, range of motion (ROM), tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and talar tilt (TT).Results:This cohort were followed up for 12 to 29 months (average, 17.2 months). At the last follow-up, AOFAS score (86.5±8.0), FFI (14.5±1.6), VAS score (1.5±1.0), Takakura staging (2.7±1.3), ROM (39.4°±8.0°), TAS (92.4°±6.0°), TT (3.7°±4.4°) were significantly improved than the preoperative values (68.3±14.4, 43.7±3.0, 4.2±1.4, 3.2±0.8, 43.3°±7.6°, 78.2°±8.3° and 7.0°±5.1°), and dorsal extension (10.9°±4.4°) was significantly smaller than the preoperative value (13.6°±5.1°) (all P<0.05). There were no significant differences between preoperation and the last follow-up in plantar flexion (29.7°±4.6° versus 28.5°±5.2°) or TLS (77.8°±4.5° versus 78.1°±5.3°) ( P>0.05). Conclusions:Supramalleolar dome osteotomy has shown promising short-term clinical efficacy in the treatment of varus-type ankle arthritis. It can significantly relieve pain, improve function, substantially correct deformity and retard progression of arthritis, but it may affect dorsal extension.
ABSTRACT
Objective:To investigate the factors influencing the prognosis of talar neck fractures of Hawkins type Ⅲ.Methods:A retrospective analysis was performed of the 18 patients with complete follow-up data who had been treated from October 2013 to December 2016 at Department of Orthopedic Trauma, Beijing Jishuitan Hospital for talar neck fractures of Hawkins type Ⅲ. They were 14 males and 4 females with an average age of 35.1 years (range, from 17 to 50 years). There were 3 open fractures. All the patients were treated with one-stage open reduction and internal fixation. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used to evaluate the functions of ankle and hindfoot during follow-up. The correlations were analyzed between the ankle-hindfoot AOFAS scores and the factors which might have influenced the prognosis, like gender, age, smoking, alcoholic drinking, body mass index, injury cause, medial malleolus osteotomy/fracture, combined fracture, open injury, interval from injury to surgery, operation time, implants (cannulated/plate or Kirschner wire) and infection.Results:The 18 patients were followed up for 21 to 41 months (average, 29.3 months). Of them, 3 had superficial infection which responded to anti-inflammatory therapy and 3 had deep infection which was improved after debridement in 2 cases and led to eventual removal of the talus in one. Tibiotalar arthritis occurred in 6 patients and subtalar arthritis in 10. The AOFAS ankle-hindfoot scores at the last follow-up for this cohort ranged from 12 to 96 points (average, 63.4 points). Ischemic necrosis of the talus was observed in 6 cases and talar collapse in one. The ankle-hindfoot AOFAS scores were strongly correlated with open fracture ( P=0.015,) operation time ( P=0.001), Kirschner wire fixation ( P=0.006), and postoperative infection ( P=0.008). Conclusions:Since open fracture, operation time ≥3 h, Kirschner wire fixation and postoperative infection may be the significant factors that may influence the prognosis of talar neck fractures of Hawkins type Ⅲ, reasonable treatment protocols can help improve the outcomes.
ABSTRACT
Objective:To explore whether the deep deltoid ligament (DL) rupture affects the mid-term clinical efficacy of pronation-external rotation (PER) ankle fracture or not.Methods:A ret-rospective study was conducted to analyze the clinical data of 50 patients with ankle fracture of PER type Ⅲ or Ⅳ who had been treated at Department of Orthopedic Trauma, Beijing Jishuitan Hospital from January 2013 to December 2014.They were 37 males and 13 females with an average age of 30.2 years(from 16 to 68 years). According to their type of medial ankle injury, the patients were divided into 2 groups.The experimental group, consisting of 28 patients with deep DL rupture but no medial ankle fracture, did not undergo DL repair operation; the control group, consisting of 22 patients with supracollicular medial malleolar (SMM) fracture but no deep DL rupture, underwent open reduction and internal fixation (ORIF) for SMM.Both groups were treated with ORIF of fibular fracture in addition to syndesmosis screw fixation.The 2 groups were compared in terms of the medial malleolus space and distal tibiofibular space on the imaging exams at more than 6 months, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analog scale (VAS) pain scores at the mid-term follow-ups.Results:The differences between the 2 groups in gender, age and mode of concomitant subluxation or dislocation were statistically significant ( P<0.05), but there were no sig-nificant differences between the 2 groups in injury violence, height of fibular fracture line, presence of total dis-location, rate of posterior malleolus fracture, rate of posterior malleolus fixation, implant removal, or operation time ( P>0.05).Imaging exams were conducted for 38 patients at 6 or more months after surgery.The medial malleolus space was 3.7 mm and the distal tibiofibular space 4.5 mm for the 21 cases in the experimental group; the medial malleolus space was 3.4 mm and the distal tibiofibular space 4.4 mm for the 17 cases in the control group.The 3-year follow-up AOFAS scores of the experimental group and the control group were 98.3 and 94.6 respectively; VAS scores were 0.4 and 1.5; the 5-year follow-up AOFAS scores of the experimental group and the control group were 97.1 and 93.6 respectively,and VAS scores were 0.5 and 1.2 respectively.Logistic regression analysis of ordered multi-classification showed that the AOFAS and VAS scores at 3-year and 5-year follow-ups had no significant correlation with the deep DL rupture for the patients<45 years old( P>0.05).Patient age was correlated with the 5-year follow-up AOFAS scores ( P=0.021). Conclusion:In ankle fracture of PER type Ⅲ or Ⅳ treated with lateral malleolar and syndesmosis screw fixation, nonoperative treatment of the deep DL rupture may not influence the mid-term clinical efficacy for the patients less than 45 years old.
ABSTRACT
Objective To investigate the incidence and surgical fixation-related factors of posterior malleolus fracture in the treatment of ankle fractures.Methods A retrospective study was conducted of the 703 inpatients with ankle fracture at Department of Foot and Ankle Surgery,Beijing Jishuitan Hospital from June 1,2017 to May 31,2018.Of them,464 suffered posterior malleolus fracture.The incidence and surgical fixation rate of posterior malleolar fracture were calculated.Of the patients with posterior malleolus fracture,the gender,age,injury energy,Lauge-Hanse classification,Bartonícek classification,talar backward subluxation,fragment area ratio (FAR) of posterior malleolus fracture on X-ray film and CT cross section,fragmental dislocation,and Die-punch fragment were analyzed to screen out the risk factors related to surgical internal fixation for posterior malleolus fracture.Results In this study,the incidence of posterior malleolus fracture was 66.00％ (464/703) and the surgical fixation rate 43.97％ (204/464).The gender,age,injury energy,Lauge-Hanse classification,direction of talar subluxation and displacement of Die-punch fragments were not the risk factors related to the surgical internal fixation for posterior malleolus fracture (P ＞ 0.05) while the Bartonícek classification,talar backward subluxation,FAR of posterior malleolus fracture on X-ray film and CT cross section,lateral fragmental displacement and Die-punch fragment were the risk factors related to the surgical internal fixation for posterior malleolus fracture (P ＜ 0.05).Logistic regression analysis indicated that the talar backward subluxation (OR =5.580,95％ CI:1.623 ～ 19.181,P =0.006) and the FAR ≥ 15％ on CT cross section (OR =9.103,95％ CI:3.342 ～ 24.800,P =0.000) were independent risk factors for surgical internal fixation of posterior malleolus fracture.Conclusions The incidence and surgical fixation rate of posterior malleolar fracture are very high.The talar backward subluxation and the fragment area ratio ≥ 15％ on CT cross-section are independent risk factors for surgical internal fixation of posterior malleolus fracture.
ABSTRACT
Objective To analyze the associations of age and gender with post-operative outcomes after pilon fracture and the effect of interaction between age and gender on the outcomes.Methods A retrospective cohort study was performed of the 101 successive patients with pilon fracture who had been treated by open reduction and internal fixation from March 2009 to November 2013 and completely followed up.The distributions of potential prognostic factors (diabetes,injury mechanism,open fracture,Rüedi-Allg(o)wer classification and AO classification) were analyzed in different age and gender groups.The outcomes were evaluated in terms of reduction quality by the Burwell-Charnley criteria,time for return to work,traumatic osteoarthritis by Kellgren-Lawrence grading scale and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.The odds ratio and regression coefficients were estimated by Logistic regression and linear regression model;P values for interaction between age and gender were estimated by likelihood ratio tests.Results Of all the 101 pilon patients,84 were male and 12 were the aged.The distributions of gender (P =0.028) and mechanism (P =0.032) were significantly different between the aged and the younger patients,showing there were more females in the aged patients and low-energy injury was more likely to cause a pilon fracture in the aged patients.As multivariate analyses suggested,with the above influencing factors controlled,a median follow-up of 41.2 months revealed age was an independent favorable prognostic factor for reduction quality (OR =3.919,P =0.041).The association between gender and time for return to work was significantly different between the aged and the younger patients,as indicated by interaction analyses (P =0.030).Conclusions There may be more females in the aged patients with pilon fracture than in the younger ones.It is likely that the aged patients sustain a pilon fracture because of low-energy injury and achieve a fracture reduction of poorer quality.Although the quality of reduction may be poorer for the aged,there may be no significant difference between the aged and the younger patients in the mid-long-term AOFAS score.It is advisable for surgeons to provide personalized treatment to better help the patients.
ABSTRACT
Objective:To summarize the CT features of ankle fracture and to analyze the relationship between the CT images and the most commonly used ankle fracture classification.Methods: With 369 cases of adult ankle fractures analyzed retrospectively,the CT images 1 cm above the ankle joint and its characteristics,the Danis-Weber classification of ankle fracture were studied,and so was the relationship between CT images and the fracture classification.Results: There were 8 forms of CT images.With a,b,and c referred to the fibular fracture,posterior malleolar fracture and interosseous tibiofibular ligament (IOL) rupture respectively.369 CT imges had 40 cases of 0 degree injury (fibula,posterior malleolus,IOL all intact);60 cases of Ⅰa degree injury (fibular fracture,posterior malleolus and IOL intact),3 cases of Ⅰb degree injury (fibula intact,posterior malleolus fracture,IOL intact),26 cases of Ⅰc degree injury (fibula and posterior malleolus intact,IOL rupture);163 cases of Ⅱab degree injury (fibula and posterior malleolus fractures,IOL intact),6 cases of Ⅱac degree injury (fibular fracture,posterior malleolus intact,IOL rupture),61 cases of Ⅱbc degree injury (fibula intact,posterior malleollar fracture,IOL rupture);10 cases of Ⅲ degree injury (fibular fracture,posterior malleollar fracture and IOL rupture).According to the Danis-Weber classification,there were 18 cases of type A,238 cases of type B,94 cases of type C,and 19 cases without fibular fracture.The prevalence of IOL rupture were 0,5.9％,and 88.3％ in types A,B,and C respectively.There was a correlation between the CT image and Danis-Weber classification,the incidence of IOL rupture was changed with the severity of Danis-Weber classification,and the difference was statistically significant after the rank correlation test (Spearman R=0.781,P<0.001).IOL rupture not determined by the fracture classification was found with the CT images and the incidence was 5.9％.Conclusion: Cross-sectional CT images 1 cm above the ankle joint can clearly determine the IOL injury pre-operatively with a good correlation with the Danis-Weber fracture classification,IOL rupture unrecognized with the fracture classification can also be noticed with the CT image.
ABSTRACT
Objective To compare biomechanical effects of augmentative plating assisted by different types and numbers of intramedullary nails in the treatment of nonunion of femoral shaft fracture after intramedullary nailing.Methods Twenty-five specimens of synthetic femur were randomly divided into an experimental group (20 bones) and a control group (5 bones).All the bones were made into models of nonunion of femoral shaft fracture after intramedullary nailing.The control group was subjected to no augmentative plating.The experimental group was further divided into 4 subgroups (n =5) which were subjected to fixation respectively by:a 7-hole plate with 3 bicortical screws on each side,a 7-hole plate with 3 unicortical screws on each side,a 5-hole plate with 2 bicortical screws on each side,and a 5-hole plate with 2 unicortical screws on each side.The torque values of all the subgroups were measured and compared when the models were subjected to torsional angles of 5°,10°,15°,20° and 25°.Results The anti-torsional strengths at torsional angles of 5°,10°,15°,20° and 25° in the 4 experimental groups were all significantly greater than in the control group(P ＜ 0.05).At a torsion angle of 25°,the mean torque value in the 3-bicortical-screw group (46.51 ±6.66 nm) was significantly greater than in the 2-bicortical-screw group (39.03 ±8.52 nm) (P ＜0.05).At torsion angles of 5°,10°and 25°,the mean torque values in the 3-unicortical-screw group (13.48±1.68 nm,23.29±3.72 nm and 48.19±5.34 nm,respectively) were significantly greater than in the 3-unicortical-screw group (9.56 ± 3.62 nm,16.99 ± 5.49 nm and 38.69 ± 6.56 nm,respectively) (P ＜ 0.05).At torsion angles of 20° and 25°,the mean torque values in the 3-unicortical-screw group (39.15 ± 5.07 nm and 48.19 ± 5.34 nm) were significantly greater than in the 2-bicortical-screwgroup (32.50 ± 5.65 nm and 39.03 ± 8.52 nm) (P ＜0.05).Conclnsions The anti-torsional strength of fixation by 3 screws on each side is significantly greater than by 2 screws on each side.When the number of screws is the same,there is no significant difference between fixation by unicortical locking screws and that by bicortical conventional screws.Augmentative plating with 3 unicortical screws or 3 bicortical conventional screws on each side is recommended for treatment of nonunion of femoral shaft fracture after intramedullary nailing.
ABSTRACT
Objective:To analyze the clinical parameters of the patients with femoral neck fracture such as general condition,therapy method,hospitalized expense so as to provide more effective management plan for the clinical work.Methods:The patients with femoral neck fracture above 50 years who received in-patient treatment from 2008 January to 2012 December were admitted into this study.We collected and analyzed the information,such as age,chronic medical disease,therapy method,hospitalized duration and expense and so on.Results:There were 1 794 femoral neck fracture patients above 50 years (male/female=1/2.06)in our hospital in recent 5 years and the annual average rate of increase was 7.3%. The average age of the patients was (69.9 ±10.7)years and the annual average rate of increase was 0.6%.The chronic medical disease diagnosis ratio was 55.0%.The average waiting time for operation was (6.8 ±4.2)days and the average hospitalized duration was (12.9 ±4.9)days which showed down-ward trend in recent years. The most popular operations were cannulated screw internal fixation (41.8%)and artificial femoral head replacement (34.1%).In the study,146 cases (7.9%)received nonsurgical treatment which showed downward trend.The average hospitalized expense was (35 075 .7 ± 1 1 343.2)yuan which showed no obvious change in recent years.The cost for the females was more than that for the males.The expense for hemiarthroplasty and total hip arthroplasty increased while that for cannulated screw internal fixation decreased gradually.Conclusion:The cannulated screw internal fixa-tion and artificial femoral head replacement were the most important operations for the patients with femo-ral neck fracture.The number and the average age of the patients were on the rise while the expense showed no obvious change in recent years.
ABSTRACT
Objective To evaluate primary open reduction and wire-pin fixation for total dislocation of talus.Methods A retrospective study was conducted of the 12 patients who had been admitted into our hospital from October 2009 to December 2013 for total talar dislocation without fracture of the talar neck or body and had been available for complete follow-up.They were 10 males and 2 females.Their range of age was from 17 to 56 years (average,34.2 years).The total dislocation was open in 4 cases and close in 8.All of them underwent primary open reduction and wire-pin fixation.The functions of ankle joint and hindfoot were evaluated according to the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.Results The follow-up time ranged from 22 to 72 months (average,35.6 months).Postoperatively,one case suffered skin necrosis and another superficial infection,both of whom responded to skin flap transferring after debridement.Traumatic arthritis of the talotibial or subtalar joint was found more or less in 7 cases,one of whom complained of severe pain but refused the subtalar arthrodesis advised.Their AOFAS scores at the final follow-up ranged from 42 to 96 points (average,72.2 points).Five cases developed avascular necrosis of the talus,but no talar collapse happened.Conclusions Primary open reduction and wire-pin fixation is effective for treatment of close total talar dislocation and open total dislocation of Gustilo type Ⅲ A or below.Although avascular necrosis and traumatic arthritis are common postoperative complications,satisfactory functions can be achieved if there is no collapse,severe pain or infection.
ABSTRACT
Objective To explore the clinical results of total ankle replacements with the Scandinavian Total Ankle Replacement (STAR) prosthesis for end-stage ankle arthritis.Methods Data of 73 cases with end-stage ankle arthritis who received Scandinavian total ankle replacement from January 2005 to May 2013 were retrospectively analyzed.They were 34 males and 39 females,with an average age of 59.6 years old (range,37-76 years old),average body mass index (BMI) of 25.3 kg/m2 (range,21.8-28.0 kg/m2).All patients were classified into stage-3 arthritis according to Morrey-Wiedeman.Kofoed,American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analog scale (VAS) were used to evaluate the function of foot and ankle.Patients with a hindfoot deformity below 10° were compared with those who above 10°;and patients above 55 years old were compared with those who below it.Results 5 replacement failed (2 liner ruptured and received replacement;2 metal components displaced,1 received TTC fusion and the other underwent revision with inferior tibiofibular joint fusion,the last patient suffered from deep infection and received the STAR removal and secondary fusion) in 73,and the rest were followed up for 12 to 110 months (average,55.2 months).59 patients were satisfied with or without reservations.The satisfaction rate was 80.8％ (59/73).The pre-op values of AOFAS,Kofoed,VAS and range of motion (ROM) were 46.6±3.5,43.0±4.7,8.7±0.7,34.4°±7.1° and the post-op values were 86.6±4.3,82.6±4.6,3.0±1.0,45.1°±8.2° respectively,and all were significantly improved compared with before.The AOFAS,AOFAS Function and ROM values of patients below 55 years old were 86.1±3.8,47.0±2.7,45.7°±7.0°,and the same values of patients above 55 were 86.7±4.6,46.8±3.1,44.9°±8.8°.The AOFAS,AOFAS Function and ROM values of patients with above 10° coronal deformity were 86.1±4.7,47.0±2.7,43.0°±7.7°,and the same values of patients below 10° were 86.8±4.2,46.8±3.1,46.1°±8.2°.There was no difference between the groups.Conclusion The STAR is the preferable surgical treatment option in patients with end-stage ankle arthritis,showing high reliability and effectivity in pain relieving and function improvement.
ABSTRACT
Objective To explore the short-term clinical outcomes of ankle arthrodesis for the treatment of posttraumatic ankle arthritis.Methods Retrospectively study the data of 47 patients with posttraumatic ankle arthritis who were followed up after receiving ankle arthrodesis from January 2008 to May 2012.There were 28 males and 19 females,with an average age of 44 years (range,14-72 years).All of them wereclassified into stage-3 arthritis according to Morrey-Wiedeman,among whom 31 had obvious foot varus deformity or equines deformity,and 16 were almost normal in appearance.The ankle joint function of patients were assessed by Kofoed,American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score,Maryland foot score systems and visual analog scale (VAS) preoperatively and at the last follow-up.Results The patients were followed up from 5 to 52 months (average,25 months).All the ankles got fused at the last follow-up,with one receiving removal of internal fixation and debride because of infection.Forty-three patients were satisfied with or without reservations; the others thought it so.The satisfaction rate was 91.5％(43/47).The Kofoed,AOFAS,Maryland foot scores and VAS were significantly improved from 48.11 ±5.00,53.38±5.52,49.74±5.71,7.89±0.87 to 80.96±6.07,82.21±4.26,88.94±5.14,2.28±1.10 respectively at the last follow-up.The normotopia X-ray of ankle joint showed that there were 22 cases in which the ankle got fused at neutral position,19 cases in which the eversion was less than 5°,3 cases in which the eversion was between 5° to 10°,2 cases in which the varus was less than 5°,and 1 case in which the varus was between 5° to 10°.Lateral X-ray showed that there were 32 cases in which the ankle got fused in dorsiflexion neutral position,12 cases plantar flexion 5°,and 3 cases plantar flexion 5° to 10°.Conclusion Ankle arthrodesis is still the preferable surgical treatnent option in patients with end-stage ankle arthritis,which shows high reliability and effectively in correcting deformity,pain relieving and function improvement.

Objective To explore clinical effect of self-made traditional Chinese medicine for hand-foot-mouth disease.Methods 118 cases with hand-foot-mouth disease were randomly divided into two groups.The control group(n=59)were treated by regular western medicines.On that basis,the study group(n=59)were treated bys elf-made traditional Chinese medicine.And the curative effects of two groups were observed.Results Fever subsidise time of the study group after treatment was(2.0±0.7)d,which was significantly shorter than that of the control group,with P＜0.05.Rash subsidise time of the study group after treatment was(3.9±0.9)d,was significantly shorter than that of the control group,with P＜0.05.Length of hospital stay of the study group after treatment was(3.5±1.3)d,was significantly shorter than that of the control group,with P＜0.05.Total effective rate of the study group after treatment was 94.9％,which was significantly higher than that of the control group(81.4％),with P＜0.05.Conclusion Self-made traditional Chinese medicine for hand-foot-mouth disease has good clinical curative effect,has high security and reliability.
ABSTRACT
Objective To explore the diagnosis and treatment of the fracture of posterior medial tubercle of the talus (PMTT). Methods From June 1993 to January 2002, eighteen patients were definitely diagnosed by CT scan as fractures of PMTT, but three of them had been misdiagnosed at their first visit. Of the 14 patients of them whose subtalar joint was involved, open reduction and internal fixation (ORIF) was adopted in eight, plaster cast fixation in five, and conservative management in one who had rejected any surgical procedures. Of the other four cases, plaster cast fixation of six weeks was applied in three, and excision of fracture fragments was performed in one. Results The mean follow-up was 41.7 months. Evaluation was done according to AOFAS (American Orthopedic Foot & Ankle Society) system. Satisfactory outcome was achieved in one of the first misdiagnosed patients after excision of fracture fragments. Of the others who received operative treatment, excellent result was achieved in seven cases, good in six cases and fair in three cases. The result for the one who refused surgery was poor. Conclusions The fracture of PMTT should be definitely diagnosed by CT. It should be treated operatively by means of internal fixation with half-threaded Titanium screws. Satisfactory outcome can be achieved by excision of fracture fragments for patients who were misdiagnosed at first.
ABSTRACT
Objective To summarize the early complications caused by the screws of AO titanium plate in the operative treatment of the displaced intraarticular calcaneus fracture (DIACFs). Methods 60 patients with calcaneal fractures were treated with ORIF (open reduction with internal fixation) using the AO plate. Results All the cases were followed up for 22 months. There appeared 1 case of screw loosening and 2 cases of improper screw location. Conclusion Although the AO titanium plate can improve the anatomic restoration of the calcaneus shape, sufficient preoperative preparation should be made to secure accurate placement of the screws so that the screw problems can be reduced.
