Acetabular fractures involving the weight-bearing dome if reduced by closed means can be maintained by heavy lateral and longitudinal traction resulting in good clinicoradiologic outcome comparable with operative management.
Acetabulum fractures are being increasingly seen with low impact injuries in elderly patients. This article aimed to study systematically literature on geriatric acetabulum fractures. Objectives of this systematic review were to study (1) demography of patients, common mechanisms of injury and types of fracture patterns commonly seen in elderly patients, (2) treatment used for these fractures in literature and (3) mortality rates in elderly with these fractures. Methods: Systematic search was carried out in May 2020 using predefined search strategy for all studies published in the English language in last 20 years. Literature search and data abstraction was done by two independent reviewers. Results: After screening of all abstracts, a total of 48 studies were included in the systematic review. In total there were 7876 geriatric patients with acetabulum fractures. Mean age of the patients was 72.47 years. There were 4841 males (61.5%). Fall from low heights was the most common mechanism of injury, present in 47.12% patients followed by motor vehicular accidents in 28.73%. Most common fracture pattern was both column fracture, seen in 19.03% patients, followed by anterior column and posterior hemitransverse fracture in 17.23%, anterior column fractures in 17.13%, and posterior wall fractures in 13.46% patients. Out of total 5160 patients for whom details of treatment were available, 2199 (42.62%) were given non-operative treatment, 2285 (44.28%) were treated with ORIF of acetabulum fracture, 161 (3.12%) were treated with percutaneous fixation and 515 (9.98%) were treated with primary THA. Gull sign, femoral head injury and posterior wall comminution were associated with poorer prognosis after ORIF and may form an indication for a primary THA. Conclusion: Literature on treatment of geriatric acetabulum fractures is not enough to draw any definite conclusions. There is limited evidence from current literature that surgery could be considered a safe treatment option for displaced acetabulum fractures in elderly. Primary THA can provide early mobility and reduce chances of resurgery in fracture patterns where restoration of joint surface may not be possible.
Background:The behavior of pelvic ring fractures in the long run has been very sparsely studied. The purpose of this study is to assess the long-term outcome of pelvic ring fractures.Materials and Methods:A total of 24 patients with pelvic ring fractures, not involving the acetabulum, were followed up for an average duration of 33 months (range 24–49 months). The clinicoradiological assessment was done using the pelvic scoring system adapted from Cole et al. Parameters assessed included sacroiliac (SI) joint involvement and, among SI joint injuries, the presence of a fracture disruption and the degree of displacement.Results:Pain and limp were present in 13 patients (54.2%) each and residual working disability in 9 patients (37.5%). The overall Cole's pelvic score was 31.3 ± 7.02 of a total score of 40. The average pelvic score in patients with SI disruption was 29.2 ± 6.75; much lower than patients without SI disruption with an average score of 34.9 ± 6.25 reaching statistical significance. The pelvic score among patients with a displacement ≤10 mm was 33.0 ± 3.92 and with a displacement >10 mm 25.88 ± 7.14. The difference was statistically significant.Conclusions:Pelvic ring injuries can lead to long term problems significantly. The involvement of the SI joint affects the long-term outcome adversely, more so if the residual displacement is >10 mm. The pelvic scoring system is comprehensive and depicts subtle differences in the outcome, which the individual parameters of the assessment fail to show.
23 years old male presented with inferolateral dislocation of proximal tibiofibular joint associated with popliteal artery and common peroneal nerve injury. The extension of the injury to involve the interosseus membrane up to the distal tibiofibular joint. The association of popliteal artery injury is not reported before to the best of our knowledge.
Management of neglected acetabular fractures is a difficult task. Osteosynthesis in such cases may not be an ideal solution because of the femoral head damage due to pressure by the fractured acetabular edge, avascular necrosis, difficulty in mobilizing the fragments due to callus formation, difficulty in indirect reduction of the fracture fragments and macerated acetabular fragments all contributing to inadequate fracture reduction. Majority of such fractures are now treated with total hip replacement. While treating such fractures with THR, problems associated with neglected acetabular fractures such as fracture non-union, hip dislocation, protrusio, cavitary bone defect or peripheral bone defect must be considered. 3D computed tomography scan provides a clear view about the acetabular and periacetabular bony anatomy. Impaction grafting and antiprotrusio cage or ring with a cemented acetabular cup can address most of the hip protrusio and cavitary bone defects. Segmental bone defect needs cortical strut-bone graft fixation and subsequent implantation of a cemented or uncemented acetabular cup implantation. Fracture non-union needs approximate reduction and fixation with plates followed by bone grafting and implantation of an acetabular cup. Despite these efforts, the outcome of THR in neglected acetabular fracture is considerable worse than after conventional hip replacement.
