Purpose: To analyze the clinical outcome of triple arthrodesis for the posttraumatic arthritis after calcaneal fractures. Materials and Methods: We retrospectively reviewed 22 posttraumatic arthritis patients who underwent a triple arthrodesis from March 1991 to May 1998. The mean duration of follow up was 74 months(range, 36-123 months). The pain, function and alignment were evaluated by the modified ankle-hindfoot scale of the American Orthopaedic Foot and Ankle Society(AOFAS) clinically and the union rate, the duration of union and the degenerative change of adjacent joints radiographically were evaluated. Results: The mean duration from injury to arthrodesis was 33 months (range, 12-132 months). The AOFAS score improved from 36.4 points(range, 14-64) preoperatively to 67.6(range, 25-90) postoperatively. The union rate was 90.1% radiographically, the mean duration of union was 14.3 weeks(range, 12-21 weeks) and the degenerative change in the adjacent joint was showed in 12 patients(54.5%). There were 2 cases of talonavicular nonunion, one superficial wound infection and one partial skin necrosis. Conclusion: Triple arthrodesis for posttraumatic arthritis after calcaneal fractures is a useful method for relief of pain and correction of posttraumatic hindfoot deformity, as an evidenced by the satisfactory clinical outcome. Although a high prevalence of subsequent arthritis of the ankle and midtarsal joint was noted radiographically, we found that it was not clinically relevant.

Past research has reported that the common causes of ankle arthritis include trauma, congenital deformity, and degeneration. Among them, fracture-induced post-traumatic arthritis is most common. For patients with ankle fractures, an anatomical reduction is performed through surgical treatment. However, insufficient reduction or malunion of the fracture site may change the alignment of the ankle joint, resulting in valgus or varus deformities. Currently, most operative options for valgus arthritis aim to either restore joint alignment and/or reduce the uneven load on the cartilage. In this report, we would like to share our clinical experience of a patient with posttraumatic valgus ankle arthritis caused by severely comminuted fracture and dislocation. A satisfactory outcome could be obtained with combined fibular lengthening osteotomy and medial displacement calcaneal osteotomy.

Purpose: To describe the recent clinical results and complications of total elbow arthroplasty based on the literature review. Materials and Methods: The indications of total elbow arthroplasty include rheumatoid or inflammatory arthritis, posttraumatic arthritis, anklylosed elbow, tumor resection which cannot recover elbow function by other reconstructive procedures, and comminuted distal humerus fracture in elderly patients. Complications are aspetic loosening, infection, prosthesis fracture, periprosthetic fracture, ulnar neuropathy, ectopic ossification, triceps insufficiency, dislocation, and bushing wear. Results and Conclusion: Mean 10 year survival rate following total elbow arthroplasty has been reported 85% on the basis of revision. The prognosis in patients with an inflammatory arthritis is reported to be best, and loosening rate in patients with a posttraumatic arthritis tends to be high. Complication rate is known to be higher than that of other joint arthroplasty. In particular, deep infection occurs in 3~5% of the patients. Total elbow arthroplasty provide satisfactory results when it is performed properly in selected patients who have an elbow joint with irreversible dysfunction and low level activities.

Purpose: This paper reports the surgical treatment results of open calcaneal fractures performed at the author's clinics focusing on open calcaneal fractures to help understand the appropriate treatment and realistic outcomes. Materials and Methods: This study was conducted on 22 cases out of 30 patients who visited the hospital from February 2009 to December 2019 and were followed up for more than one year. In open fractures, the fracture was classified using the Gustilo-Anderson classification and was evaluated using the soft tissue status at the time of visit. Intra-articular calcaneal fractures were classified using Sanders classification. The radiological parameters were measured for the Böhler angle, Gissane angle, calcaneal length, height, and width before and after surgery, and at the last follow-up. The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and investigated complications. In addition, statistical analysis of the incidence and associated factors of posttraumatic arthritis was conducted. Results: In all cases, the surgical treatment was performed by minimally invasive surgery. The AOFAS ankle-hindfoot scale conducted for a clinical evaluation of the final follow-up was averaged 72.5 points. In the classification of open fractures, the Gustilo-Anderson classification type IIIA was the most common, and the Sanders type III was the most common. Of the 22 cases after surgery, 15 cases had complications, 11 cases had posttraumatic arthritis, eight cases had an infection, and 4 cases had both complications. Only the Sanders classification showed a statistically significant correlation with the incidence of posttraumatic osteoarthritis (p-value 0.032). Conclusion: In treating open calcaneal fractures, internal fixation by a minimally invasive approach showed relatively satisfactory results. However, follow-up research will be needed, including the results of a long-term follow-up through a large number of cases and comparative studies with other surgical methods.

Purpose: The prognosis of total hip replacement (THR) after open reduction and internal fixation (ORIF) versus THR following non-operative treatment of acetabular fractures is unclear. Few studies have been conducted in this regard. Therefore, the purpose of the current study was to perform an assessment and compare the functional outcomes for study subjects in the ORIF and non-ORIF groups during the follow-up period compared to baseline. Materials and Methods: This longitudinal comparative study, which included 40 patients who underwent THR for either posttraumatic arthritis after fixation of an acetabular fracture or arthritis following conservative management of a fracture, was conducted for 60 months. Twenty-four patients had undergone ORIF, and 16 patients had undergone nonoperative/conservative management for acetabular fractures. Following THR, the patients were followed up for monitoring of functional outcomes for the Harris hip score (HHS) and comparison between the ORIF and non-ORIF groups was performed. Results: The HHS showed significant improvement in both ORIF and non-ORIF groups. At the end of the mean follow-up period, no significant variation in scores was observed between the groups, i.e., ORIF group (91.61±6.64) compared to non-ORIF group (85.74±11.56). A significantly higher number of re-interventions were required for medial wall fractures and combined fractures compared to posterior fractures (P <0.05). Conclusion: THR resulted in improved functional outcome during follow-up in both the groups; however, the ORIF group was observed to have better functional outcome. Re-intervention was not required for any of the posterior fractures at the end of the mean follow-up period.

Purpose: To analyze the clinical and radiological outcome of subtalar arthrodesis using cannulated screws and morselized bone graft. Materials and Methods: Twenty one patients with follow-up of more than 1 year after subtalar arthrodesis were included in this study. Mean age was 40.8 years, and mean follow-up duration was 38 months. Underlying diseases were 19 cases of posttraumatic arthritis (18 calcaneal fractures and 1 talar fracture) and 2 cases of tarsal coalition. Clinically AOFAS ankle-hindfoot score, operation time, complication and satisfaction of patients were analyzed. Radiologically time to union, arthritis of surrounding joints, preoperative and postoperative talar declination angle were analyzed. Results: AOFAS ankle-hindfoot score was improved from preoperative 33 points to postooperative 79 points. Eighteen patients (86%) were satisfied with the results. Mean operation time was 91 minutes. All cases were fixed with 1-2 cannulated screws and morselized bone graft. Mean time to radiologic union was 12.1 weeks. There was 1 case of delayed union. There was no significant perioperative changes in talar declination angles. Conclusion: Subtalar arthrodesis using cannulated screws and morselized bone graft seems to be relatively simple and effective treatment method for subtalar arthritis.

Slight protrusion of the dorsum of midfoot without degenerative arthritis is common and usually can be treated by avoiding pressure of the shoe. Primary or posttraumatic degenerative arthritis accompanied by severe functional disability is treated by realignment and arthrodesis of the involved joints. We report a case of osteophytic changes in the form of lipping at the base of the first metatarsal and medial cuneiform which was treated by resection of the spurs. The cause of these spurs may be the congenital coalition of the first metatarsocuneiform joint.

Purpose: To evaluate the results of open reduction and internal fixation for displaced talar neck fracture. Materials and Methods: Fourteen patients were followed for more than 1 year after open reduction and internal fixation of displaced talar neck fracture. The mean age was 41.5 years, and the mean follow-up period was 3.8 years. There were 10 type II, 3 type III and 1 type IV fractures per Hawkins. There were 3 open fractures. Clinically AOFAS ankle-hindfoot scale and Hawkins criteria were utilized. Radiologically quality of reduction, duration of bony union, avascular necrosis and posttraumatic arthritis were evaluated. Results: At last follow-up, AOFAS scale was mean 89.1 points. There were 8 excellent, 4 good, and 2 fair results according to Hawkins criteria. Radiologically anatomical reduction was obtained in 13 cases. Mean duration of bony union was 11.8 weeks. There were 3 avascular necrosis and 2 post-traumatic arthritis. There was no significant difference in the incidence of avascular necrosis between early operation group and surgically delayed group. Conclusion: Accurate open reduction and rigid internal fixation seem to be prerequisites for satisfactory treatment of a displaced talar neck fracture.

The purpose of this study Is to assess the retained range of motion[RROM] of the foot after arthrodesis of the ankle joint, which might help designing the angle of arthrodesis. We reviewed the results including the RROM in 14 cases of ankle arthrodesis. Underlying causes included trauma group(six posttraumatic arthritis) and disease group(three osteoarthritis, three Charcot joints, one chronic synovitis and one pyogenic arthritis). We measured the RROM on the lateral roentgenograms of the ankle in full dorsiflexion and plantarflexion, The results were assessed by the AOFAS hindfoot scale[score]. The RROM in sagittal plane was $23.4{\pm}5.3$ degrees and the score was 71.5 points on average. The RROM and the score were $26.8^{\circ}{\pm}2.1$, 81.2 points respectively in trauma group and $20.8^{\circ}{\pm}5.6$, 64.3 points in disease group; $26.6^{\circ}{\pm}2.3$, 83.4 points in cases younger than 40 years of age and $21.6^{\circ}{\pm}5.7$, 64.9 points in the older. The mean score was 77.3 points in cases whose RROM were $24^{\circ}$ or more and 61 points in cases of less RROM; 69.6 and 73.4 points in cases with and without adjacent degenerative arthritis respectively. The score was 69.7, 73.3 and 71.5 points in cases whose angle of arthrodesis was in dorsiflexion, neutral, plantarflexion respectively. In conclusion, after ankle arthrodesis RROM of the foot was $23.4^{\circ}$, and the more the RROM, the higher the score. In cases with sufficient amount of RROM, the angle of fusion on sagittal plane might not influence the result significantly.

Calcaneal fractures account for 2% of all fractures and approximately 60 to 70% of tarsal fractures. These fractures typically are the result of high-energy injury, such as a motor vehicle accident or a fall from a height. The potential for disabling malunion following intrarticular displaced calcaneal fracture is high, regardless of treatment. Fracture displacement typically results in loss of hindfoot height, varus and widening of the hindfoot, with possible subfibular impingement and irritation of the peroneal tendon and/or sural nerve. Frequently, subtalar joint develops posttraumatic arthritis. In symptomatic patients with calcaneal malunion, systemic evaluation is required to determine the source of pain. Nonsurgical treatment, such as activity and shoe modification, bracing, orthoses, and injection, is effective in many patients. Surgical treatment may involve simple ostectomy, subtalar arthrodesis with or without distraction, or corrective calcaneal osteotomy. A high rate of successful arthrodesis and of patient satisfaction has been reported with surgical manamgent.
