Racing performance after hemicircumferential periosteal transection for angular limb deformities in thoroughbreds: 199 cases (1987-1989).
Abstract: Racing records of 199 Thoroughbred foals with angular limb deformities surgically treated by hemicircumferential periosteal transection and elevation (HCPT) from 1987 through 1989 (principals) were compared with records of their 1,017 siblings (controls) for starting status; 2-, 3-, and 4-year-old starts; earnings and earnings per start; and starts percentile ranking number (SPR). Principals had a slightly lower percentage of horses starting a race (45 vs 55%), fewer 2-year-old starts (1.06 vs 1.72), and lower SPR (33.49 vs 49.18), compared with those of controls (P < 0.05). Starting status was significantly (P < 0.05) affected by surgery and the horse's sex, but not by anatomic site treated. Fillies were 1.74 times less likely to start than were colts, regardless of surgery, whereas principal fillies were 2.63 times less likely to start than were control colts. Difference was not detected between principals and controls in 3- or 4-year-old starts; 2-, 3-, or 4-year-old earnings, or earnings per start. Horses treated with distal metacarpal/metatarsal HCPT had fewer 2-year-old starts (1.09 vs 2.19), but did not have a significantly different SPR or lower starting percentage, compared with values for controls. Horses treated with distal radial HCPT had lower starting percentage (48 vs 55%), fewer 2-year-old starts (1.22 vs 1.70), and lower SPR (32.53 vs 53.32), compared with those of controls.(ABSTRACT TRUNCATED AT 250 WORDS)

This study looks at the racing performance of 199 Thoroughbred foals with angular limb deformities who were treated with hemicircumferential periosteal transection and elevation (HCPT) surgery. The performance results were then compared to those of their siblings who were not treated with the surgery.
Objective
To understand the effect of hemicircumferential periosteal transection and elevation (HCPT) surgery on the racing performance of Thoroughbred foals with angular limb deformities and recognize the factors that contribute to the performance decline, if any.
Participants
- A total of 199 Thoroughbred foals having angular limb deformities and underwent HCPT surgery between 1987 and 1989 comes under the principal group.
- The control group comprised 1,017 siblings of the principal horses who did not acquire HCPT surgery.
Parameters
- Starting status: The percentage of horses that participated in a race
- Racing starts at age 2, 3, and 4
- Total earnings and earnings per start
- The percentile ranking of each racing start (Starts Percentile Ranking number (SPR))
Results
- The principal group had a lower starting percentage and fewer two-year-old horse starts compared to the siblings. The SPR value was also lower for the principal group (all differences were significant at p < 0.05).
- The decision to participate in a race was significantly influenced by the horse’s gender and whether it had had surgery. Regardless of the surgery, fillies were less likely to participate than colts, and principal fillies were even less likely to begin than the control colts.
- No significant difference was observed between principals and controls concerning the number of starts at three or four years old, total earnings at 2, 3, or 4 years old, and earnings per start.
- Horses that underwent distal metacarpal/metatarsal HCPT had fewer two-year-old starts but did not show a significantly different SPR or lower starting percentage
- Horses treated with distal radial HCPT had a lower starting percentage, fewer two-year-old starts, and a lower SPR compared to the control horses.
