“…DAL-SDFT results in increased strain on the SDFT in vitro, and is reported to increase the risk of suspensory desmitis in the treated limb in Thoroughbred racehorses (Hogan and Bramlage 1995). However, it has been used with reasonable success, with between 52 per cent and 82 per cent of treated horses returning to race at least five times without re-injury (Ordidge and others 1996, Fulton and others 1994, Hogan and Bramlage 1995, Gibson and others 1997, Alexander and others 2001, Hu and Bramlage 2014). …”

To evaluate a treatment protocol whereby superficial digital flexor (SDF) tendonitis in Thoroughbred and Standardbred racehorses was treated with autologous bone marrow aspirate (ABMA) obtained from the sternebrae. This treatment was combined with desmotomy of the accessory ligament of the SDF tendon (DAL-SDFT) in selected cases. Medical records of 105 horses treated using the reported protocol were reviewed. Signalment, history and details of treatment were recorded. Racing records were reviewed and performance recorded. Of Thoroughbreds, 82 per cent had one or more starts within the follow-up period and 59 per cent had five or more starts. Of Standardbreds, 76 per cent had one or more starts and 62 per cent had five or more starts. A statistically significant difference was found when comparing race starts between sexes, with females having less starts than males (≥1start P=0.017 and ≥5 starts P=0.008, respectively). The proportions of horses having one or more starts and five or more starts did not differ significantly if a DAL-SDFT was performed or not (P=0.31 and 0.63, respectively). Horses with a core lesion in the body of the SDFT have a good prognosis for return to racing following intralesional ABMA injection. Addition of DAL-SDFT to the treatment regimen did not significantly influence outcome.

“…It is less clear how desmotomy may aid in the repair process of the injured tendon. In analogy with observations concerning superior check ligament desmotomy, the increased check ligament–tendon length after desmotomy and subsequent healing may reduce the likelihood of the tendon exceeding the maximum check ligament–tendon unit excursion, thereby reducing the likelihood of re‐injury (Hu and Bramlage ).…”

“…In this study, Alaine Hu and Larry Bramlage from the USA assessed the post operative likelihood of racing, career longevity and convalescent time in Thoroughbred racehorses with superficial digital flexor tendonitis (SDFT) in the forelimbs treated by desmotomy of the accessory ligament of the superficial digital flexor tendon (i.e. superior check ligament desmotomy [SCLD]).…”

colleagues in the USA have recently published their retrospective study evaluating the short-and long-term outcomes of 50 horses that underwent palmar or plantar digital neurectomy due to chronic foot pain, and related this outcome to preoperative factors including magnetic resonance imaging (MRI) findings.Magnetic resonance imaging and radiographic analyses were conducted retrospectively by a single operator for each imaging modality. Variables such as age, breed, sex, athletic activity, lameness duration and response to local anaesthesia were analysed to assess if they were associated with likelihood of post operative lameness; logistic regression was then performed to assess the relationship between the variables, long-term survival was also assessed. The included horses competed at a low-level in a range of disciplines. Those horses that had persistent lameness following local anaesthesia were found to have an increased likelihood of post operative lameness compared to those whose lameness completely resolved following this diagnostic procedure. Time to follow-up varied but overall 92% of horses became sound following surgery, with 80% and 70% remaining sound at 15 months and 30 months, respectively. Neuroma formation was a complication in 2 cases. The median time to reoccurrence of lameness was 20 months. Those horses that were found to have a core or linear lesion of the deep digital flexor tendon (DDFT) on MRI were significantly more likely to have lameness recurrence following surgery.This study provides useful data to inform clients of the potential long-term outcome of a palmar or plantar digital neurectomy, when MRI findings are available. Horses with a core or linear DDFT lesion are less likely to respond to this surgical procedure than those without. Racehorse injuries after corticosteroid injectionIn this retrospective cohort study, R. Whitton and colleagues in Australia and the UK compared the rates of musculoskeletal injury (MSI) in horses receiving local corticosteroid injection (LCI) with those that were untreated and those prior to treatment.Of the 1911 horses in this study, 392 were treated with an injection of corticosteroid into or adjacent to a synovial structure, muscle or tendon/ligament. Limb injuries following which the horse did not race for at least 6 months, or was retired were classified as MSIs. Hazard of injury following injection was compared to that in untreated horses and those prior to treatment to calculate the hazard ratio (HR). All 392 horses were administered at least one LCI, with most LCIs performed bilaterally and intra-articularly into the carpal or fore fetlock joints. Carpal injuries, fore fetlock and forelimb tendon injuries were the most common of the 219 MSIs that ocurred. Following LCI the hazard of MSI was greater (HR 4.83) than the incidence rate of MSI in untreated horses and those prior to injection (1.22 injuries/100 horse-months). The hazard ratio returned to pretreatment levels after 49 days. The hazard for MSI in horses following second and subsequent LCI...
