ABSTRACT
Objective To investigate the clinical results and related key points of surgical treatment for Hawkins Ⅲ talus neck fractures.Methods From March 2005 to March 2010,26 patients with Hawkins Ⅲ talus neck fracture were treated and 21 of them were followed,including 13 males and 8 females,with an average age of 37.6 years.The fractures occurred on the left side in 11 patients and on the right side in 10patients.The mechanism of injury included high falling injury in 13 patients,traffic accident injury in 7 patients and rolling down injury in 1 patient.Five cases were closed fractures and 6 cases were open fractures.A bilateral approach,the medial and lateral approaches,was used to perform the operation with cannulated screw fixation in emergency.After external fixation in functional position for 6 weeks without loading,ankle joints were allowed to take exercise with hinge brace and to bear partially basing on plain radiograph 12-16weeks later.The weight-bearing should be adjusted with follow-up.Functional results were assessed according to AOFAS (American Orthupaedic Foot and Ankle Society,AOFAS)score.Results The average duration of follow-up was 36.6 months (range,6-60 months).All fractures gained union and the average union time was 4.5 months.The average AOFAS score was 78.6.There were 4 cases in excellent results,10 in good,5 in fair and 2 in poor.The overall excellent and good rate was 67.8％.Traumatic arthritis occurred in 13 cases and avascular necrosis in 5 cases.Conclusion The effect of surgical treatment for Hawkins Ⅲtalus neck fracture via a bilateral approach is satisfactory.
ABSTRACT
Objective To analyze, treatment of ipsilateral Pilon and calcaneal fractures (IPCF). Methods Injury causes included fallings in seven patients, traffic injury in two and impact injury in one, with ISS score of 5-22 points. There were seven patients with open injuries and 3 with close ones. Nine pa-tients had Ⅱ-Ⅲ degree of Pilon fractures according to the AO/OTA classification and six comminuted com-pression calcaneal fractures according to the Essex-Loprest classification. The Pilon fractures were fixed by cannulated nail, screw or Kirschner wire through open reduction in six patients including four fixed with ex-ternal fixators (the calcaneal fractures were fixed with percutaneous eannulated nail or Kirschner wire by poking reduction). The calcaneal fractures were fixed with only Kirschner wire through poking reduction in two patients and double fractures treated conservatively in two. Results The reduction of Pilon and cal-caneal fractures treated by operation were markedly improved in six patients, while there occurred angular deformity and joint surface introeession in the patients treated conservatively. The wound healing of soft tis-sue was sound in seven patients but unsatisfactory in the other three. The ankle-hind foot score was 82-94 points in four patients who were followed up. Conclusions IPCF is caused by the high energy force and characterized by severe injures of the soft tissues and the bone tissues at the distal tibia and calcaneua, for which limited internal fixation plus external fixation are suitable treatment choice.
