Aim: The retrospective evaluation of external fixation as a treatment of choice for fractures of humeral diaphysis.

Material – Method: 24 patients with an equal number of fractures of humerus diaphysis (21 closed, 3 open) were treated with external fixation. Time to bony union, the seriousness and type of complications, the clinical, radiological and functional outcome were evaluated. The minimum time of follow up was six months.

Results: Excellent 20, good 2, fair 1, poor 1. The cause of fair and poor results was limitation of shoulder motion. 22 fractures united within 2–5 months. Complications were 2 cases of non-union, 3 pin-track infections, 3 remanipulations. There was no case of deep infection at the fracture site and no iatrogenic injury of the radial nerve.

Conclusion: The external fixation, used in the treatment of humerus fractures, is a semi-interventional method, easy to apply, well-tolerated by the patient and with very good functional results. It a very good alternative of both the conservative treatment and internal fixation.

Introduction: Heterotopic ossification around the tip of intramedullary nail is a well-known complication of the nailing technique, since the time of Kuntscher. Nevertheless, little attention has been given to it in the current literature.

Aim: The evaluation of the incidence, clinical significance and possible risk factors of this complication after intramedullary nailing of femur with reaming.

Material – Method: For this purpose we studied the X-rays and medical charts of 30 patients who had undergone the above procedure at the Orthopaedic Departments of both Institutions mentioned above, between 2000 and 2002. The preoperative diagnoses were diaphyseal fracture: 13 patients, subtrochanteric fracture: 7 patients, refracture of femur: 1 patient, non-union: 5 patients, imminent fracture (due to intraosseous lesion): 2 patients, failure of previous fixation: 2 patients. In 18 cases the G.K. nail was used, whereas, in the remaining twelve, the long gamma nail was used. The patients’ follow-up ranged from 6 to 18 months (mean: 11 months). The presence of heterotopic bone around the proximal tip of the nail was graded according to the grading system of Brumback et al.

Results: In 12 patients (40%) there was no development of heterotopic bone around the proximal tip of the nail. In 14 patients (47%) minimal and moderate grade of heterotopic ossification was developed (grade I and II). Finally, in 4 patients (13%) there was significant heterotopic bone formation (grade III). None of the above patients presented with any significant limitation of ipsilateral hip joint motion. There was no correlation between type of fracture, type of nail fixation, presence of concomitant injuries, nail prominence above the tip of greater trochanter and the formation of heterotopic bone. The only positive correlation was between male sex and the presence of heterotopic ossification.

Conclusion: Heterotopic ossification of minimal and moderate grade is a common complication of the technique of intramedullary nailing of femur, without any further clinical significance. The formation of heterotopic bone of significant degree in the hip region, though it does not results in serious clinical problems for the patient, it will surely make future extraction of the nail difficult.
