Ollier’s disease is very rare condition that is characterized by the presence of multiple cartilaginous tumors in the long tubular bones which can lead to severe deformities and pathological fractures at early age. More commonly the lesions have a unilateral distribution. We report a case of an adult patient with medical history of Ollier’s disease involving both hips treated with a 2-stage bilateral total hip arthroplasty (THA) using a cement less ace tabular cup and a short cement less femoral stem, achieving excellent clinical and radiographic results.

Enchondromas are common benign usually asymptomatic cartilage tumors, which develop in the metaphyses and may become incorporated into the diaphyses of long tubular bones, in close proximity to growth plate cartilage [1-2]. They usually occur as a single lesion (solitary enchondroma). Occasionally, multiples enchondromas may appear and it is defined as a enchondromatosis. Which encompasses several subtypes among which the most common are Ollier’s Disease and Maffucci’s Syndrome. The estimated prevalence of enchondromatosis is 1/100.000 [3].

Ollier’s disease is defined by the presence of multiple enchondromas (3 or more), and characterized by an asymmetric distribution of cartilaginous lesions that can be extremely variable in terms of size, number, location, age of onset and diagnosis, and requirement for surgery [4]. It also can be associated with pathological fractures [5].

The diagnosis is usually based on clinical and radiological features. Radiographies typically show multiple, radiolucent, homogenous lesions with an oval or elongated shape and well defined slightly thickened bony margin [2]. Biopsy does not play an important role in the diagnosis. Further diagnostic analysis such as CT scan, MRI, scintigraphy, ultrasonography might be helpful during the follow-up.

Herein, we report on a case of Ollier’s disease of the proximal femurs treated with a THA with a 2,5-year follow-up. After extensive literature review we could not find previous reports regarding this rare clinical presentation.

Case Presentation

A 37-years-old male patient, with Ollier’s disease and a 10-year history of mild-moderate pain in both hips and thighs associated to weakness and limp. Pain was mild at rest and exacerbated by walking. There was no history of trauma, fever or night pain. After several consultations he came to our department for further examinations and treatment.

Physical examination showed a limb discrepancy of 4 cm. The range of motion of the right hip was 60–20° of flexion and extension with a moderate flexion contracture. The range of motion of the left hip was 60º-10º of flexion and extension. Right hip internal rotation was to 15° and external rotation to 30º, while for the left hip the internal rotation was to 15º and external rotation was to 35º. His right hip passive abduction was limited to 10°, and adduction was similarly limited to 15°. The left hip had a passive abduction to 25º and an adduction limited to 10º. At the end of the clinical examination the Harris Hip Score was 62. Therefore, a varus deformity of the left knee and valgus deformity of right knee were evident. The radiological findings suggested of multiple enchondromatosis of the both proximal femurs that involved the epiphysis and metaphysis.

In November 2013 we decided to perform a THA in the left side using a 54-mm cement less acet abular cup and short cement less femoral stem (GTS, Biomet) through a posterolateral approach with the Femur First Technique. Intraoperatively, the hip was stable with a good range of motion and no subluxation or impingement. The patient began physiotherapy the next morning and 18 hours after the procedure he was able to bear partial weight with assistance. There were no subsequent complications and the patient was discharged home after 12 days, according to our protocols with proper hip precautions. At 6-month follow-up the patient was able to bear complete weight, without any symptoms and could perform the daily activities.

At 2-year follow-up, clinical and radiographic results were excellent, and the patient was satisfied. On the clinical exam of the left hip the range of motion achieved 110º of flexion. Internal rotation was to 20° and external rotation to 35º. His left hip passive abduction was to 35°, and adduction was up to 20° with a Harris Hip Score up to 75. Thus, at this time point, we decided to schedule and perform a second THA on the right hip using the same materials and technique, achieving a remarkable outcome without any complications. At 1 year follow up, the patient was satisfied and was able to walk without limp. The clinical exam was notoriously improved achieving a Harris Hip Score up to 93 [Figure 1-3].

Ollier’s disease is a very rare condition, which symptoms frequently develop during the first decade of life, unlike our case. As stated above, it almost exclusively affects the metaphysis of long bones and the small bones of the hands and feet [2]. There are very few reports of single enchondromas of the hip in english literature [5-6], and only one case of multiple enchondromas located on the hip like our patient.

The patient was a 37-year-old male with an Ollier’s disease that involved both hips. Clinical features were characteristic of this condition: limb inequality with asymmetric shortening of the right limb, loss of hip function and a flexion contracture. Additionally, a valgus and varus deviation of both knees was present. Treatment of Ollier disease is usually conservative and often the lesions are left untreated. Indications for surgery are very variable and predominantly depend on the presence of deformity, limb-length discrepancy, pathological fracture, and malignant transformation. According to Kumar et al. the goals of the treatment are achieving mechanical alignment and equivalent limb length for normal walking, and relieving pain from a pathological fracture [7].

Due to the characteristics and localization of the enchondromas, there is not a standardized surgical treatment [7]. In this particular case, considering the anatomic localization of the lesions in both proximal femurs, without involving the diaphysis, and the functional limitation of the hip joints, we proposed a bilateral THA performed in a two-stage intervention. Given the lack of evidence in this matter, we first performed the left hip arthroplasty and, in the view of the remarkable results that were achieved at 1-year follow-up, we then proceeded to the second THA.

Ollier’s disease might be a challenging condition to treat, because of the great variability not only in the clinical presentation, but also in the size, number and localization of the enchondromas. It is well known that surgical approach varies from case to case. Enchondromatosis with bilateral hip involvement is very unusual and, in our case, we considered THA was the best available therapeutic option, allowing us to improve substantially the joint anatomy and function. Thus, we believe total hip arthroplasty should be taken into consideration in similar cases.
