Unusual combination of femoral head dislocation associated acetabular fracture with multipart femoral fractures: Case report

Closed reduction of hip dislocation associated with ipsilateral lower extremity fractures: A case report and review of the literature

BACKGROUND

Traumatic hip dislocation usually occurs following high-velocity trauma. It is imperative that the dislocation be reduced in a timely manner, especially in a closed manner, as an orthopedic emergency. However, closed reduction can hardly be achieved in patients who also have ipsilateral lower extremity fractures. Herein, we focus on hip dislocation associated with ipsilateral lower extremity fractures, excluding intracapsular fractures (femoral head and neck fractures), present an early closed hip joint reduction method for this injury pattern, and review the literature to discuss the appropriate closed reduction technique for this rare injury pattern.

CASE SUMMARY

We report a case of a 37-year-old male who sustained a left acetabular posterior wall fracture, an ipsilateral comminuted subtrochanteric fracture and dislocation of the hip. The hip dislocation was reduced urgently in a closed manner using the joy-stick technique with a T-shaped Schanz screw. The fractures were reduced and fixed as a 2nd-stage surgery procedure. At the 17-month postoperative follow-up, the patient had full range of motion of the affected hip.

CONCLUSION

Closed reduction of a hip dislocation associated with ipsilateral lower extremity fractures is rarely achieved by regular maneuvers. Attempts at closed reduction, by means of indirectly controlling the proximal fracture fragment or reconstructing the femoral leverage rapidly with the aid of various external reduction apparatuses, were shown to be effective in some scenarios. Mandatory open reduction is indicated in cases of failed closed reduction, particularly in irreducible dislocations.

Effect of Wearing Medical Masks on Perioperative Respiratory Complications in Older Adults with Hip Fracture: A Retrospective Cohort Study

PURPOSE

Respiratory complication is one of the major challenges in the treatment of older adults with hip fractures. However, no study so far has investigated the effect of wearing medical masks on the prevention of perioperative respiratory complications in these patients.

PATIENTS AND METHODS

In this retrospective cohort study, 1016 consecutive patients aged ≥65 years with hip fractures were included and assigned to two groups: the control group and the observation group. The two groups received the same perioperative management modalities. In addition, patients in the observation group were asked to wear medical masks for protection. Data of patients' demographics, fracture type, surgical methods, comorbidities, the incidence of perioperative respiratory and other complications, and hospital outcomes were collected and compared between the two groups. Subgroup analyses were also performed stratified by fracture types.

RESULTS

A total of 1016 patients (292 females and 724 males) with a mean age of 79.4±7.3 years were analyzed in the study, including 533 in the control group and 483 in the observation group. The overall incidence of perioperative respiratory complication, and the incidence of pulmonary infection, respiratory failure and arrhythmia in the observation group were significantly lower than the control group, especially in winter and spring. There was no difference in other complications, hospital length of stay, and total hospital costs. Further subgroup analyses showed that the incidence of heart failure and arrhythmia in the observation group was lower than that in the control group for patients with femoral neck fractures, which was different from patients with intertrochanteric fractures.

CONCLUSION

The incidence of perioperative respiratory complications, including pulmonary infection and respiratory failure, could be reduced in older adults with hip fractures by strengthening personal protection, including wearing medical masks, especially in winter and spring. Wearing medical masks could also effectively reduce the incidence of perioperative heart failure and arrhythmia in femoral neck fracture patients and do not increase the incidence of other complications and the burden of hospitalization.

Decoding the behaviour of extracapsular proximal femur fracture- dislocation - A systematic review of a rare fracture pattern

PURPOSE

Proximal femoral extracapsular fractures with associated ipsilateral hip dislocation is an extremely rare pattern of injury. These fractures may be associated with a spectrum of severity from isolated trochanteric fractures to comminuted intertrochanteric and subtrochanteric fractures with hip dislocation. To date, this pattern of injury is not described in any injury classification system and no clear cut guidelines for the same are available. The aim of this review is to provide an evidence based pooled analysis of the existing literature and develop guidelines that help surgeons tackle this rare injury pattern.

METHODS

A comprehensive review of the literature was undertaken using the PRISMA. Case reports and series of Extracapsular proximal femoral fracture dislocations published in PubMed, EMBASE, Springer, OvidSP, ScienceDirect, Web of Science and Google scholar between inception of journals to May 2020 were included in the review. A pooled analysis comparing the demography, pattern of the fracture, mode and mechanism of injury with the clinical and radiological outcome and complications was performed.

RESULTS

52 cases from 46 case studies were included in the pooled analysis. There was a near significant association between avascular necrosis and mean time to reduction (p = 0.0865). Individuals with compound injury had 10.12 times higher risk of avascular necrosis (p = 0.009). No significant association between the pattern of proximal femur fracture and incidence of avascular necrosis (p = 0.116, chi-square). There was no significant association between polytrauma and poor clinical outcomes. (p = 0.231).

CONCLUSIONS

Principles of damage control orthopaedics should be followed in unstable patients with this rare fracture dislocation. Percutaneous Schanz screw reduction manoeuvre can be attempted gently with a low threshold to perform an open reduction. Every attempt at salvaging the fractured hip must be performed in young individuals with an arthroplasty standby for comminuted and unreconstructable cases.
