Huckstep intramedullary nailing for non-union of humeral shaft fractures

A lifelong story: Case report of a humeral shaft nonunion successfully treated after 30 years

Nonunion of the humeral shaft occurs in 2%-10% of nonsurgically treated fractures and in up to 15% of fractures treated by primary open reduction and internal fixation. Gunshot humerus shaft fractures are a frequent type of injury; the degree of comminution and bone loss, as well as soft tissue disruption may influence the healing process, causing major sequelae with loss of function. Here we describe a 30 years old midshaft nonunion of the humerus, that occurred in a young woman after a gunshot. She was initially treated with hanging cast with definitive nonunion and secondary loss of limb function. After 30 years, careful management of the non union fracture ends, locked intramedullary nailing and bone grafting harvested from the femoral canal using the Reamer Irrigator Aspirator (RIA) system led to union with recovery of limb function.

Treatment of non-union of humerus diaphyseal fractures: a prospective study comparing interlocking nail and locking compression plate

BACKGROUND

The aim of this prospective comparative study was to compare outcomes and complications of humeral diaphyseal fracture non-unions managed with humerus interlocking nail (HIL) and locking compression plate (LCP).

MATERIALS AND METHODS

40 patients with non-union of humeral diaphyseal fractures were included in this study and were randomly allocated in two groups; group A had 20 cases treated with HIL and group B had 20 cases treated with LCP. Clinico-radiological assessments were done for each case up to 2-year follow-up period. Primary outcome measures (time to fracture union, union rate) and secondary outcome measures (functional outcome and complication such as infection, malunion, delayed union, implant failure, joint stiffness and iatrogenic radial nerve palsy) were compared between both the groups. Disabilities of the arm, shoulder and hand (DASH) scoring and Steward and Hundley's scoring system were used to assess functional outcome of the fracture fixation.

RESULTS

There was no significant difference (p = 0.12) in terms of mean fracture union time between group A (15.8 ± 4.2 weeks) and group B (17.2 ± 3.8 weeks). Group A had 95 % union rate and group B had 100 % union rate (p = 0.14). At the 2-year follow-up visit, there was no significant difference found between both the groups regarding range of motion of shoulder and elbow joint. There was no significant difference found in final functional outcomes between both the groups on comparing DASH score (p = 0.14) and Steward and Hundley's score (p = 0.08). In terms of complications, there was insignificant difference found between both the groups.

CONCLUSIONS

This study concludes that both the implants can be used in non-union of humeral shaft fractures with good functional outcomes and acceptable rate of complications.

Treatment of nonunions of humeral fractures with interlocking intramedullary nailing

OBJECTIVE

To introduce the experience of treating nonunions of humeral fractures with interlocking intramedullary nailing.

METHODS

Twelve patients with humeral nonunions were treated with interlocking intramedullary nailing. The time interval between trauma and surgery was 10.5 months on average. Open reduction with anterograde approach was performed. Axial compression was specially applied to the fracture site with humeral nail holder after insertion of distal locked screws. Iliac bone grafting was added.

RESULTS

The average follow-up period was 21 months (ranging 9-51 months). All patients achieved osseous union 5.8 months after treatment on average. Eleven patients had good functions of the shoulder joints and the upper extremities. No patient experienced any permanent neurological deficit. Refracture of the original ununited region occurred in one patient after removal of the internal fixator one year later, but union was achieved after closed re-intramedullary nailing fixation.

CONCLUSION

Humeral interlocking intramedullary nailing is an effective alternative treatment for humeral nonunion.
