Objectives: To describe the clinical and ultrasonographic features, treatment and outcome of curb in a Thoroughbred flat racing population. Study design: Retrospective case series study Methods: Cases with ultrasonographic evaluation of curb were retrieved from medical records at the Hong Kong Jockey Club from 2006 to 2025. Data analysed included signalment, clinical presentation, ultrasonographic findings, treatment, rehabilitation period, and performance indices. Results: 32 limbs of 27 horses were affected; plantar fasciitis was present in all cases, superficial digital flexor tendonitis in two limbs (6%) and long plantar ligament desmitis in one limb (3%). The left (n=17), right (n=5) or both hindlimbs (n=5) were affected. Treatment included a variable period of rest and variable use of systemic and local anti-inflammatory medication, cold therapies, radial pressure wave therapy, focused shockwave therapy, class IV therapeutic laser and therapeutic ultrasound. Horses resumed trotting, galloping and racing within a median 20 days, 58 days 108.5 days respectively. The prognosis for return to racing without re-injury was good with 92.3% of horses that underwent a rehabilitation program racing after injury. There was a low recurrence rate, with curb-related lameness recurring in two horses after resuming trotting exercise necessitating more time walking. Main limitations: Limited case number, variable quality and completeness of stored ultrasound images and clinical notes, and multiple factors that can affect racing outcome. Conclusions: Periligamentous and peritendinous fasciitis is the predominant ultrasound finding in flat-racing Thoroughbred horses. Involvement of the underlying superficial digital flexor tendon and long plantar ligament is unusual. The prognosis for return to racing is favourable following adequate rest and rehabilitation.
