A multicentre study of 285 cases was performed to enhance the management of distal phalangeal fractures on the basis of clinical evidence. The outcome after treatment was available for 223 of the cases. Horses with a non-articular type I fracture had a better prognosis (91.7%) for return to original or expected level of use than horses with an articular type II or III fracture (69.6% and 74.1%, respectively). The prognosis for types IV and V fractures was fair (57.7% and 57.1%, respectively) and for type VI good (80%).

Tendon and ligament injuries continue to be one of the most frequent causes of orthopaedic injury and early retirement in the Thoroughbred racehorse. In the UK, the Horserace Betting Levy Board has invested considerable research funding in the last decade in order to investigate aspects of tendon epidemiology, biology and therapy, in order to decrease both the welfare and economic consequence of such injuries. This review summarises key aspects of this research effort and identifies specific research directions for the future.

Reasons for performing study: Diagnostic navicular bursoscopy has been described in limited cases. Review of greater numbers is needed to define its contribution to case management and prognostic values.

Reasons for performing study: Traumatic injuries are a major cause of morbidity and mortality in the horse and consequently pose a serious threat to horses' wellbeing. To date, there have been no published studies assessing the frequency of injuries in the general horse population of the UK.

Objectives: To obtain information regarding husbandry management strategies and injury prevalence in horses aged ≤15 years, with the aim of identifying predisposing risk factors for injury.

Reasons for performing study: Injuries of the calcaneal insertions of the superficial digital flexor tendon and their relationship to displacement of the tendon from the calcaneus have not previously been reported.

Objectives: To describe findings made on clinical cases with disruption of the calcaneal insertions of the superficial digital flexor tendon (SDFT) including observations on their role in horses with unstable subluxation of the tendon. To describe novel surgical techniques and the results of treatment.

There have been no detailed ultrasonographic descriptions of injuries of the accessory ligament of the deep digital flexor tendon (ALDDFT) in the carpal and proximal metacarpal and tarsal and proximal metatarsal regions. The aims of this study were to describe the: 1) normal ultrasonographic appearance of the proximal aspect of the ALDDFT in fore- and hindlimbs and 2) clinical and ultrasonographic features of proximal injuries of the ALDDFT in both fore- and hindlimbs.

Objective To report on the outcome of wounds to the hindlimb of racehorses, and horses with the intended use of racing, where both the long digital extensor (LoDE) and lateral digital extensor (LaDE) tendons had been completely transected. Design Retrospective case series. Methods Records of all horses admitted with hindlimb lacerations between 2002 and 2009 were examined for cases where both the LoDE and LaDE tendons in the hindlimb had been severed, and specifically in horses intended to be used for racing.

The magnetic resonance (MR) imaging features, signalment, clinical history and outcome of 55 horses with a penetrating sole injury were evaluated. Our aim was to describe MR imaging findings within the hoof capsule, assess the utility of the technique and give recommendations for the optimal MR imaging protocol to evaluate such injuries. Data from five equine hospitals were analyzed retrospectively. The tract was more likely to be visualized in animals scanned within the first week postinjury. There was no significant predisposition based on breed, age, or gender.

Eight sports horses with unilateral (4) or bilateral (3) forelimb or unilateral hindlimb (1) lameness had subtle radiologic abnormalities of the subchondral bone of the sagittal groove of the proximal phalanx associated with moderate or intense increased radiopharmaceutical uptake. High-field or low-field magnetic resonance (MR) imaging confirmed the presence of a fissure fracture or subchondral and trabecular bone trauma. Seven of eight lesions were located approximately midway between the dorsal and palmar cortices of the proximal phalanx; the eighth was sited more dorsally.
