Subtalar coalition: a case report.

Chua C, Yeap E, Yazid M - Malays Orthop J (2013)

Bottom Line: We followed up the patient for two years and the result was excellent with full range of movement of his right ankle and subtalar joint attained within two months.He returned to athletic activity by six months and was discharged with no complications after two years.She defaulted follow up after seven months as she was very satisfied with the result.

ABSTRACT

Unlabelled: Subtalar coalition is an uncommon condition that usually manifests in early adolescence(1). Frequently, this condition is missed. Delayed diagnosis may result in osteoarthritis requiring triple arthrodesis. Here, we report two patients with subtalar coalition. The first patient is a 12 year old boy who presented with right ankle pain for one year and was treated with excision of the coalition and bone wax insertion at the excision site. We followed up the patient for two years and the result was excellent with full range of movement of his right ankle and subtalar joint attained within two months. He returned to athletic activity by six months and was discharged with no complications after two years. The second patient is a 15 year old girl who presented with bilateral ankle pain and swelling for three years and was treated with excision of the coalition and subtalar interpositional arthroplasty bilaterally. She defaulted follow up after seven months as she was very satisfied with the result. We wish to highlight this condition which may be misdiagnosed as flexible flat foot or ankle sprain.

Key words: Subtalar coalition, excision of coalition, bone wax insertion, subtalar interpositional arthroplasty.

Figure 4: : CT scan of the 2nd patient showing prominent medialbony overgrowth with minimal joint space.

Mentions: On examination, there were bilateral bony swellings at thepostero-inferior aspect of medial malleolus which weretender. Skin overlying it was normal. The range ofmovements of ankles was full. Subtalar movement ofinversion and eversion were associated with pain. CT scanThe both revealed prominent bony overgrowth projectingmedially from the sustentaculum tali and the medial part ofthe talus, appear to be impinging upon the adjacent flexortendons.(Fig 4) She was diagnosed to have bilateral subtalarcoalition and was scheduled for excision of coalition withsubtalar inter-positional arthroplasty. We proceeded with theleft foot first followed by the right foot which was done three months later. Intra-operatively, the medial approach wasused and local fat graft was inserted into the subtalar jointspace and the bone ends were covered with bone wax. Thesewere applied for both sides. By six weeks, she was able tofully weight bear and returned to her daily routine. We onlymanaged to follow her up until seven months post-op and shedefaulted, presumably well. After 2 years, she was calledback for reassessment and AOFAS scoring scale .We notedthat she was very satisfied with the end result of theoperation and had thus defaulted the follow up. Thepreoperative AOFAS scoring scale for the right side in thispatient was 57 and left side was 58. After 2 years, the rightside score was 72 whereas the left side was 69. Overall, thesurgery almost totally met her expectations and she rated theend result of the surgery as very good.
