A rare concomitant ipsilateral hip and knee dislocations: A case report and review of the literature.

Ipsilateral hip and knee dislocation is a rare and complex injury that usually results from high-energy trauma. Only 14 cases were reported in the literature so far. We report the case of a 35-year-old man who presented with an ipsilateral right hip and knee dislocation after being involved in a road traffic accident. A contralateral floating knee was associated. The hip dislocation was associated to a posterior wall fracture of the acetabulum and a femoral head fracture. The knee dislocation was compound and associated with a patella fracture. The hip dislocation was reduced. The posterior wall and the femoral head fractures were treated conservatively. The knee dislocation was reduced and stabilized by external fixator. Early postoperative infection occurred and was treated surgically. At the last follow-up, the knee was ankylosed at 5° of flexion with a bony bridge between the femoral condyle and the tibial plateau. The patient described an occasional hip pain on exertion. He had full range of motion of the right hip. No avascular necrosis of the femoral head was seen. Outcomes of simultaneous hip and knee dislocation are very variable and remain unpredictable. The timing of reducing the hip joint and the knee.

Surgical management of tibia refracture with a bent intramedullary nail: A case report and review of the literature.

Intramedullary nailing is the gold standard for long bone fractures in the lower limbs. Fractures of the tibia with bending of the intramedullary nail is a very uncommon complication. Removing a bent nail is an unpredictable and challenging procedure for any trauma surgeon. We report the case of a 34-year-old man presenting a refractured tibia with a bent intramedullary nail following a motor vehicle accident. We describe the management of this patient as well as a substantial review of the literature to depict the peculiarities of this entity compared to its more commonly reported femoral counterpart. When approaching a deformed tibia nail, standard extraction techniques should be attempted and are more likely to be successful than in deformed femoral nails.

Surgical management of neck of femur fractures in patients younger than sixty-five years: a comparative study of three fixation methods.

PURPOSE: Several surgical implants have been used for the treatment of neck of femur fracture (NOF) in younger patients such as dynamic hip screw (DHS) and cannulated compression screw. However, the superiority of one or another osteosynthesis device remains a matter of debate. The aim of this work is to evaluate and compare three fixation modalities: Cannulated Hip Screws (CHS), DHS and DHS associated to anti-rotating screw for surgical treatment of femoral neck fracture in young adults. METHODS: It is a retrospective comparative study of three series of NOF fractures treated surgically over a period of ten years; including young adult patients (age > 18 years and < 65 years) treated conservatively using closed or open reduction and internal fixation. All types of NOF fractures according to Garden classification were included. Pathological, basi-cervical fractures and fractures on previously operated hips were excluded. The minimum follow-up recommended was two years. Clinical evaluation was based on the Postel Merle d'Aubigné score (PMA), the visual analogue scale (VAS), the Parker score, and the Hip Disability and Osteoarthritis Outcome Score (HOOS score). Reduction quality was assessed on X-rays. RESULTS: Our series included 72 patients that were divided in three groups: Group A: Fixation using cannulated hip screws (33 patients). Group B: Fixation using DHS only (21 patients). Group C: Fixation using DHS associated to anti-rotation screw (18 patients). The patients of group A had better PMA and VAS scores, but there was no statistically significant difference. However, a significant difference (p=0.001) was found for the HOOS score. The fractures treated with DHS associated with anti-rotating screws, had the highest loss of reduction in the vertical axis (Yp) with the highest femoral head collapse (Zp) values. Group A had the lowest loss of reduction in the horizontal axis (Xp). There was no significant difference between the three methods of osteosynthesis in terms of loss of correction though. CONCLUSION: We found comparable results in terms of healing and complication rates and loss of reduction for the three groups with no significant difference. However, the HOOS score was significantly better in the cannulated hip screw group.

Unusual case of lateral subtalar joint dislocation associated with calcaneal fracture and lateral malleolus fracture.

Introduction: Subtalar dislocation is defined by a simultaneous total separation of the talocalcaneal and talonavicular joints. Lateral variety is the rarest. It is the result of a high energy trauma. It occurs following forced eversion, with the foot locked in a rut with pressure on the lateral aspect of the leg. Articular fractures of the calcaneus occur as a result of axial impact on the greater tuberosity.We report the case of a lateral subtalar dislocation associated with a calcaneal fracture. Case presentation: A 62-year-old man who presented to the emergency room following a 9 m fall. Initial examination revealed a swelling of the right foot and ankle with a deformity giving the appearance of a "flat foot" without skin opening. The neuro-vascular examination was normal.A radiological assessment including an antero-posterior and lateral X-ray of the right ankle and a axial view if the calcaneus, showed a calcaneal articular fracture and a lateral dislocation of the subtalar joint. CT scan confirmed the diagnosis. Closed reduction by external maneuvers failed. Through a lateral mini-approach centered on the subtalar joint, open reduction of the dislocation was achieved and controlled fluoroscopically. Osteosynthesis of the calcaneal fracture was performed using a percutaneous pinning. Consolidation was obtained at 3 months post-operatively.At the last follow-up, the patient reported occasional pain. The radiological assessment showed early arthritic changes of the subtalar joint. Conclusion: In rare cases of subtalar dislocation, the direction of displacement, associated bone injuries, and open reduction would be responsible for a poor functional outcome. At present, there is no certain way to avoid subtalar osteoarthritis.

Comparison of the results of the synthesis of Schatzker II and III tibial plateau fractures by screwing versus plate.

PURPOSE: Lateral tibial plateau fractures with depression are the most common. Their treatment is currently surgical. Many therapeutic procedures have been described. Our aim is to evaluate the results of open surgery and to compare the two internal fixation methods used: lag screw versus plates. MATERIALS AND METHODS: This is a retrospective comparative study of two series of tibial plateau fractures Schatzker types II and III treated surgically over a period of ten years with two different methods: Group A: Internal fixation using screws for 86 patients. Group B: Internal fixation using plates for 71 patients. Functional and anatomical results were assessed according to Rasmussen's clinical and radiological scores. RESULTS: The patients' average age was 44 years (range from 18 to 76). The male gender was predominant (104 males and 53 females). Road traffic accidents were the most common aetiology with over two thirds of the cases. The fractures were type Schatzker II in 61% of the cases. The mean follow-up was five years. Although the clinical and radiological Rasmussen scores were better in group A (internal fixation with lag screws), those differences were statistically insignificant (p = 0.6 and p = 0.8). Group A clinical and radiological scores were 26.06 and 16.57, respectively and those of group B were 25.72 and 16.45. We noticed more sepsis and skin complications and a longer operating time (95 min versus 70 min) in group B patients with a statistically significant difference. None of the patients of our series had bone grafting. CONCLUSION: For Schatzker II and III fractures, an internal fixation with lag screws would be preferable when possible especially in the case of a pure depression fracture. It yields satisfactory results with a shorter operating time and less complication rate.
