Osteoclastoma is a benign aggressive bone tumour. Most commonly it is seen in epiphysio-metaphyseal region around knee and distal radius. Proximal ulna is a rare location for osteoclastoma. According to reports only 3 such cases have been reported in English literature. We report one such case of osteoclastoma of proximal ulna. Patient presented with painless, progressive swelling around elbow for 4 months. Resection of proximal ulna and elbow reconstruction was done using non vascularized free fibular graft. At two years follow up patient is tumour free and has functional range of movement in elbow. We are reporting the case because of its rare location and for the indigenous treatment modality of using free fibular graft for elbow reconstruction.

Osteoclastoma also known as giant cell tumour is a benign aggressive tumour. It has a slight female preponderance and is seen in the age group of 20-40yrs. Osteoclastoma is an epiphysio-meta physial tumour commonly seen in distal end of femur, proximal end of tibia and distal end of radius [1]. Treatment options include curettage with or without bone grafting, extended curettage, wide excision and reconstruction. We are reporting a case of osteoclastoma of proximal ulna. According to reports only few such cases have been reported in English literature. After evaluation tumour was resected En-bloc and joint was reconstructed using free fibular graft. This case is being reported for its rare location and the indigenous treatment modality carried out.

Case History

A 30 year old male presented with painless swelling around his right elbow for a period of 4 months (Figure 1). It was insidious in onset with gradual increase in size which later on started to affect his elbow movements. On examination a localised swelling measuring 5x 6cm in posterior aspect of elbow was seen which was non tender, hard in consistency and was continuous with proximal ulna. The overlying skin was normal. Terminal part of extension and flexion of elbow joint was limited. X-ray showed a lytic lesion involving entire proximal ulna with soap bubble appearance with destruction of articular surface (Figure 2). FNAC was done to aid the diagnosis and it showed features suggestive of osteoclastoma.

Giving a tumour free upper limb along with a functional elbow joint was a challenging part. Hence treatment plan included en-bloc excision of proximal ulna with tumour and safe margin of normal appearing bone and to reconstruct the elbow joint using free fibular graft.

Surgical Procedure

Under general anaesthesia tumour was exposed through posterior approach to elbow (Figure 3). Proximal ulna with tumour and 2cm of normal bone was excised (Figure 4). Another team of surgeons harvested required length of free fibular graft from upper fibula from ipsilateral leg. Head of the fibula was shaped to match the olecranon process of ulna and tensor fascia lata was covered over fibular head to act as articular surface (Figure 5). Graft was fixed to ulna using semi tubular plate and a K-wire was put for temporary immobilisation of elbow in 90degree flexion. Triceps tendon was sutured to the graft at proximal end. Specimen was sent for histopathological examination which confirmed the diagnosis of Osteoclastoma (Figure 6). Immediate post op X ray confirmed the proper fixation.

Follow up

Post op period was uneventful. K wire was removed after 3 weeks and mobilisation of elbow was started. Patient was regularly followed up for 2 years for radiological union of the graft, functional outcome of the elbow and for possible recurrence or metastasis to lungs. Radiological union of the graft was seen as early as 4 months. At the end of 2 years patient is pain free and has a stable and functional elbow (Figure 7). No recurrence or metastasis of tumour seen. Donor site is also pain free and patient is walking comfortably.

Osteoclastoma is a benign bone tumour but has aggressive course. It is seen after skeletal maturity with slight female preponderance. Epiphysio-metaphysical region around knee and distal end radius are favoured sites [1]. Very few cases of osteoclastoma affecting proximal ulna have been reported. First case of osteoclastoma of proximal ulna in South East Asia was reported by Sanjy BK et al. [2]. And since then only one case has been reported in this region. To best of our knowledge this is only the third that is being reported from India and 5th case ever being reported in English literature [2,3].

Usual management of this tumour involves resection of the tumour or curettage and ablation of the cavity surface. This is feasible if the tumour is located in a long bone. In a small bone, excision and reconstruction is preferred. The challenge we faced was that the tumour involved proximal part of ulna along with elbow joint of the dominant upper limb of the patient. Hence it was necessary for us keep the bone and elbow joint free from tumour as well as give him a stable, functional elbow joint. In previous reported cases excision of proximal ulna along with arthrosdes is of elbow in functional position have been done [2,3]. We planned to excise entire proximal ulna with tumour and 2cm of visible normal bone and reconstruction of elbow joint using proximal free fibular graft along with tensor fascia lata coverage to act as articular surface.

Free fibular grafts have been used frequently in orthopedics as a graft to bridge long bony gaps and in very few cases to reconstruct joints. There have been reports of it being used to reconstruct elbow joint after resection of distal end of humerus [4-6]. But reconstruction of ulnar component of elbow has rarely been attempted. Usui M et al. [7] reported that the use of a free vascularized fibular graft including the head carried a risk of fibular head collapse [7]. But such a thing has not been noticed yet by us till now in this case. In summery we were able to perform a limb saving procedure along with giving a stable functional joint using a free fibular graft. However further follow up and more research is needed in this regard to carry out this procedure as a regular treatment modality for tumours around elbow.
