MRI in patients with Haglund's deformity and its influence on therapy

Do pre-operative radiologic assessment predict postoperative outcomes in patients with insertional Achilles tendinopathy?: a retrospective database study

INTRODUCTION

Diagnosis and treatment of insertional tendinopathy of the Achilles tendon (IAT) remains a challenge. The aim of this study was to assess the influence of pre-operative radiological pathologies on the patient-reported outcomes following open debridement of all pathologies for IAT.

MATERIALS AND METHODS

In this IRB-approved retrospective correlation and comparative study, patients with pre-operative imaging were identified from the authors' retrospective IAT database comprising of 118 patients. All were treated by a standardized surgical treatment strategy utilizing a midline, transachillary approach and debridement of all pathologies. A total of fifteen radiologic parameters were measured on radiographs (RX) and MRI. The patient-reported outcomes were assessed using the Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A-G) and the general health questionnaire SF-12 at a minimum follow-up of 12 months. The data are presented as mean ± SD (95% CI).

RESULTS

88 patients (74.6%) with an average age of 50 ± 12 (47-52) years were included. Radiographs were available in 68 patients and MRI in 53. The mean follow-up was 3.8 ± 1.9 (3.4-4.3) years. The overall VISA-A-G was 81 ± 22 (77-86), the SF-12 PCS 54 ± 7 (52-55), and the SF-12 MCS 52 ± 9 (50-54) points. None of the assessed radiological parameters had a significant influence on the patient-reported outcome following surgical treatment for IAT.

CONCLUSION

In this retrospective correlation study, no significant association was found between preoperative radiographic and MRI radiologic parameters for IAT and postoperative patient-reported outcomes (VISA-A-G and SF-12).

MRI of the Achilles tendon - a comprehensive pictorial review. Part two

•

The abnormalities on MRI should be correlated with the clinical findings.

•

Higher signal of the Achilles tendon is a common postoperative finding.

•

The fluid signal within the Achilles tendon graft indicates a rupture.

•

Postoperative complications of Haglund’s syndrome should be assessed on MRI.

•

Elongation of the Achilles tendon is seen after surgical or conservative treatment.

The most common disorder affecting the Achilles tendon is midportion tendinopathy. A focal fluid signal indicates microtears, which may progress to partial and complete rupture. Assessment of Achilles tendon healing should be based on tendon morphology and tension rather than structural signal. After nonoperative management or surgical repair of the Achilles tendon, areas of fluid signal is pathologic because it indicates re-rupture. A higher signal in the postoperative Achilles tendon is a common finding and is present for a prolonged period following surgical intervention and needs to be interpreted alongside the clinical appearance.

Mulholland Deformity With Pump Bump

Mulholland/Haglund's deformity is a symptomatic posterosuperior deformity of the heel. It affects middle-aged adults in general. It is more common in females than in males. It is mainly bilateral. The etiology is still poorly understood. The potential triggers may be a tight Achilles tendon, a high arch foot, and an inherited one. After the failure of conservative means, we record a case of bilateral Mulholland deformity showing dramatic improvement in pain following surgery.
