RESUMEN
Total ankle arthroplasty (TAA) has become a popular management option for ankle arthritis. Periprosthetic osteolysis is one of the most common causes for reoperation in TAA. A CT scan should be done in all suspected osteolysis cases to confirm location, quantify size and aid in surgical planning. These patients are often asymptomatic with limited evidence regarding appropriate management. Smaller lesions should be monitored for progression in size. Periprosthetic cysts measuring 10-15mm in all three axes should be considered for debridment and curettage with autogenous bone grafting. The authors believe that bone grafting of large asymptomatic periprosthetic cysts could prevent implant failure.

Introduction: Injury surveillance is an important part of injury risk reduction in the sporting population. This study describes the type, side (dominant or non-dominant), occurrence, impact, activity of onset, and severity of foot and ankle injuries in elite South African male and female cricketers. Methods: Foot and ankle injuries sustained by elite cricket players between 2018 and 2021, obtained from the records of Cricket South Africa, were descriptively analysed. Results: A total of 104 foot and ankle injuries in 82 players were recorded. The majority (n = 100; 96%) of injuries were on the non-dominant side. Bowling (n = 31; 30%) and fielding (n = 20; 19%) contributed to most injuries. The majority were first-time (n = 83; 80%) and non-impact injuries (n = 62; 60%). Fifty percent (n = 52) of injuries rendered players unable to participate in at least one match or practice session. Lateral ankle ligament injury was the most common injury sustained (n = 36; 35%). Conclusion: The findings from this study can inform future researchers and assist healthcare service needs relating to injury risk reduction and management programmes. Effective rehabilitation programmes may reduce the risk of reinjury. Ideally, these programmes need to be role specific.
RESUMEN
BACKGROUND: Periprosthetic cysts can occur in up to 95% of total ankle arthroplasties (TAA) and have been correlated with implant failure. The aim of this study was to determine the clinical and radiologic outcomes, using computed tomographic (CT) scan, after periprosthetic cyst bone grafting and assess for the minimum cyst size that should be grafted. METHODS: A retrospective review was performed of all TAA procedures performed between 2007 and 2014 (n=93). A CT scan was done to assess cyst size and operative planning. Eight patients with 9 periprosthetic cysts larger than 1.75 cm3 were grafted and specimens sent for histology. The mean time to bone grafting was 7.3 (3.8-9.5) years. Functional outcome was assessed using the American Orthopaedic Foot & Ankle Society ankle score, visual analog scale, and Self-reported Foot and Ankle Score. A CT scan was performed at follow-up to assess graft incorporation and cyst size progression. The mean time to CT scan post grafting was 3.0 (0.7-4.7) years. RESULTS: There was no implant malalignment identified and no differences in the pre- and postoperative functional scores. Preoperatively cysts had a mean volume of 8.16 (2.04-14.03) cm3. The mean percentage incorporation was 89% (69%-100%). Eight of the grafted cysts were considered successful on CT, with the ninth having 69% incorporation. Five cysts were not grafted, as they were below 1.75 cm3, and remained the same size or had minimal enlargement. CONCLUSION: The satisfactory results in this small cohort suggests that prophylactic bone grafting may extend implant survival. We recommend that periprosthetic cysts greater than 1.75 cm3 be prophylactically bone grafted, and that cysts smaller than 1.75 cm3 be monitored for progression in size. LEVEL OF EVIDENCE: Level IV, Case Series.

AIM AND OBJECTIVE: The purpose of this study was to compare clinical results following complex proximal, midshaft, and distal tibial fractures and investigate whether there are differences in outcomes between these locations. MATERIALS AND METHODS: Patients between 18 years and 65 years of age and minimum follow-up of 12 months with complex tibial fractures treated with a circular ring fixator were included. Functional outcomes were assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) functional and bone scores, Foot Function Index (FFI), Four Step Square Test (FSST), and Timed Up and Go Test (TUG). Quality of life was assessed by the EQ-5D score. RESULTS: A total of 45 patients were included: proximal fractures, n = 11; midshaft fractures, n = 17; and distal fractures, n = 17. ASAMI functional (p = 0.8) and bone scores (p = 0.3) were not different. Excellent and good bone scores were achieved in >90% in all groups. FFI was 30.9 + 24.7 in the proximal group, 33.9 + 27.7 in the midshaft group, and 28.8 + 26.9 in the distal group (p = 0.8). TUG was 9.0 + 2.7 sec in the proximal group, 9.0+3.5 in the midshaft group, and 8.5+2.0 in the distal group (p = 0.67). FSST was 10.7 + 2.5 sec in the proximal, 10.3 + 3.8 in the midshaft, and 8.9 + 1.8 in the distal fracture groups (p = 0.5). EQ-5D index value was highest in the distal (0.72), lowest in the proximal (0.55), and 0.70 in the midshaft fracture groups (p = 0.001). EQ-5D VAS was significantly different between the proximal (65) and midshaft (82.3) (p = 0.001) and between the distal (75) and proximal (65) fracture groups (p = 0.001). CONCLUSIONS: The results of this study suggest that the functional outcomes between proximal, midshaft, and distal complex tibial fractures are comparable. Their ability to ambulate afterward is comparable to age-related normative data, but complex tasks are more difficult and better compared to the ambulating ability of a healthy population aged 65 to 80 years. Patients with proximal tibial fractures had significantly more disability by at least one functional level and/or one health dimension.

RESUMEN
BACKGROUND: Lower extremity fractures have a profound negative effect on a patient's gait and outcomes. Correction of deformity, and with it normalization of objective gait parameters, may result in better subjective and objective functional outcomes in patients treated with circular external fixation for malunited tibial fractures. AIM: The purpose of this study was to investigate the relationships between gait parameters, patient reported outcome measures (PROMs), and health related quality of life measures in patients treated with circular external fixation for the correction of deformity related to tibial malunions. METHODS: This retrospective study included patients with posttraumatic tibial deformities, aged 14-65, with a minimum follow-up of 24 months following deformity correction. Patients with congenital deformities, head injuries, spinal cord injury, neurological disorders, or contralateral lower limb amputation were excluded. Functional outcomes were assessed by the Foot Function Index (FFI); Short Form 12 (SF-12); the EQ 5D; and the ASAMI score. Gait analysis was performed using Dartfish® and the Edinburgh Visual Gait Score (EVGS). The relationships between the EVGS and functional outcome scores were analyzed using Pearsons' moment correlations with Bonferroni corrections. RESULTS: Eleven patients with a mean age of 42 (range 23-57) were analyzed. The mean EVGS was 2.6 ± 2.1, the mean FFI 29.6 ± 33.4, the mean EQ5 Index Value 0.7 ± 0.2, the mean EQ5 VAS 85.4 ± 19.5, the SF12 mean Physical Component Score (PCS) 46.7 ± 11.1, and the mean Mental Component Score (MCS) 55.2 ± 7.5. The following relationships were strong and significant: EVGS and FFI (r = 0.7; P = 0.02), EVGS and PCS (r = -0.82; P = 0.02), and FFI and EQ5 (r = -0.79, P = 0.05). SIGNIFICANCE: The results of this study suggest that correction of deformity with realignment and restoration of normal anatomy was associated with improved functional outcomes and physical well-being. Patient reported quality of life is strongly associated with patient perceived functional outcome, but not with objective gait parameters.

AIM: The purpose of this study was to compare the functional and radiological outcomes of complex tibia fractures treated with two different hexapod fixators. MATERIAL AND METHODS: This is a retrospective comparative study of patients treated for complex tibial fractures between 2010 and 2015. Inclusion criteria was patients between 18 years and 60 years of age, who sustained a complex comminuted open or closed tibial fracture with or without bone loss, who had a minimum of 12 months' follow-up, and who have been treated definitively using either Taylor Spatial Frame (TSF) or TrueLok-Hexapod System (TL-HEX). The outcome measures were Association for the Study and Application of the Method of Ilizarov (ASAMI) score, foot function index (FFI), EQ5-D, four-step square test (FSST), and timed up and go (TUG) test. Descriptive statistics were used to assess patient demographic information. Categorical variables (ASAMI and EQ5D-5L) were analysed using the χ 2 test. Continuous variables (FFI, functional tests, and radiographic outcomes) were analysed with two-tailed Student's t tests. RESULTS: In all, 24 patients were treated with the TL-HEX and 21 with the TSF. The mean time for external fixation was 219 ± 107 days (TL-HEX) and 222 ± 98 days (TSF). Union occurred in 92% (TL-HEX) and 100% (TSF). The mean follow-up was 777 ± 278 days (TL-HEX) and 1211 ± 388 days (TSF). Using the ASAMI scores, there were 17 excellent and 6 good results for the TL-HEX and 10 excellent and 11 good results for the TSF (p = 0.33). The FFI was 30 ± 28.7 (TL-HEX) and 26.1+23.9 (TSF) (p = 0.55). The EQ5D was 0.67 ± 0.3 (TL-HEX) and 0.73 ± 0.2 (TSF) (p = 0.43). The mean TUG and FSST were 9.2 ± 3.2 and 10 ± 2.9 seconds (TL-HEX) and 8.4 ± 2.3 and 9.6 ± 3.1 seconds (TSF) (p = 0.34 and 0.69). CONCLUSION: The results of this study suggest that both hexapod external fixation devices have comparable clinical, functional, and radiographic outcomes. Either fixator can be used for the treatment of complex tibial fractures, anticipating good and excellent clinical outcomes in approximately 80% patients. LEVEL OF EVIDENCE: Therapeutic level III.
