Article Abstract
Introduction: Brachymetatarsia is a rare congenital deformity characterized by a shortened metatarsal, frequently affecting the fourth ray. It can result in cosmetic concerns, pain, and functional discomfort. While distraction osteogenesis has been widely used, complications, such as joint subluxation remain a concern.
Case Report: A 21-year-old female presented with bilateral congenital brachymetatarsia of the fourth metatarsal, associated with pain and deformity. She underwent gradual lengthening using external rail fixators combined with axial trans-articular K-wire stabilization of the metatarsophalangeal (MTP) joints to prevent subluxation during distraction.
Results: The procedure resulted in satisfactory lengthening (2 cm/metatarsal), restoration of the metatarsal parabola, and full functional recovery of the MTP joints (MTPJ) without subluxation or major complications. Clinical and radiological outcomes were excellent at 6 months post-operatively.
Conclusion: The modified technique combining external rail fixators and trans-articular K-wire stabilization effectively corrected bilateral fourth metatarsal brachymetatarsia. It provided enhanced joint stability during distraction and minimized complications, such as MTPJ subluxation. This approach may be preferred in cases requiring gradual lengthening with structural joint protection.

Brachymetacarpia is the term for the shortening of the digit as a result of the metacarpal shortening. Isolated idiopathic brachymetacarpia is rarely reported in African countries, and its incidence is still unknown in the literature compared to brachymetatarsia, which is extensively reported. We report an uncommon case of a 26-year-old male patient who presented with short, symmetrical ring fingers without an associated medical condition.

Brachymetatarsia is characterized by the parabola formed through the articulation of the metatarsophalangeal joints of the toes. It is defined as the termination of one or more metatarsals at least 5 mm proximal to this parabola, most commonly affecting the fourth metatarsal. Surgical interventions for brachymetatarsia include osteotomy followed by either acute distraction with grafting or gradual lengthening via distraction osteogenesis.
