Intramedullary nailing as a safe and efficient treatment option for all types of displaced proximal humeral fractures in geriatric patients: A retrospective evaluation of 49 patients treated with the new Targon PH+ nail.

BACKGROUND

Implant specific complications and outcome for the use of proximal humeral nails in different fracture types are not well described.

OBJECTIVE

Evaluation of adverse effects and outcome of patients treated with the new Targon PH+ implant for proximal humeral fractures in a geriatric population.

METHODS

A consecutive series of patients from a single institution was retrospectively evaluated. Adverse events (AE) were assessed from patients' files and during follow-up examination. Current pain level was evaluated using the Visual Analogue Scale (VAS). The disability score of arm, shoulder and hand (DASH) as well as the Constant-Murley score were assessed. Patient satisfaction was evaluated by questionnaire.

RESULTS

Forty-nine patients with a mean age of 72.0 ± 10.0 years were included with a follow-up of 2.2 years. Five patients showed twopart fractures (10%), 24 threepart fractures (50%) and 20 fourpart fractures (40%). Additional shaft fracture occurred in twelve cases (24%). Implant-related AE were recorded in six cases (12%). Pain under strain was moderate with a mean of 27.6 ± 27.1 mm. DASH score showed a mean of 25.9 ± 24.9. Constant score of the affected shoulder was 57 ± 23.8 with a mean difference of 16 points compared to reference shoulder. No significant differences in AE, VAS, DASH or Constant score could be found according to fracture groups. Most patients were satisfied with the surgical outcome (84%).

CONCLUSIONS

The Targon PH+ nail demonstrated good functional results and low adverse events in geriatric patients. Additional studies including less experienced centres are required to further evaluate the possible benefits of this implant.
