Shoulder injury is an uncommon cause of lameness in horses. Trauma to the shoulder region may produce bone and soft-tissue damage. The present study describes the case of a severe left shoulder injury caused by blunt trauma in a 6-year-old gelding. Clinical and ultrasonographic examination revealed fracture of the supraglenoid tuberosity of the scapula and of the lesser tubercle of the humerus with fiber disruption and hematoma of the biceps brachii, bicipital bursitis, and suprascapular nerve damage.

Objective: To test single cycle to failure tensile strength characteristics of 6 suture material–pattern combinations in equine superficial digital flexor (SDF) tenorrhaphy, specifically to compare a 10-strand modification of the Savage core suture technique with the 3-loop pulley technique.

Study Design: Ex vivo mechanical experiment comparing 3 different suture patterns with 2 different materials.

Sample Population: Forelimb and hindlimb SDF tendons (n=48) harvested from adult Thoroughbred and Standardbred horses of mixed age and gender.

There is a large spectrum of radiological variants of the distal phalanx that can be seen in both sound and lame horses. Osteitis of the distal phalanx implies active inflammation, a diagnosis that can only be made supported by nuclear scintigraphy, magnetic resonance imaging or computed tomography. Osteitis of the distal phalanx as a primary cause of lameness is relatively unusual, but may be the result of acute or chronic bone trauma or be associated with adjacent laminar disruption.

Ungual cartilage ossification in the forelimb is a common finding in horses. Subtle abnormalities associated with the ungual cartilages can be difficult to identify on radiographs. Magnetic resonance (MR) imaging findings of 22 horses (23 forelimbs) with a fracture of the distal phalanx and ossified ungual cartilage were characterized and graded. All horses had a forelimb fracture. Eleven involved a left forelimb (seven medial; four lateral), and 12 involved a right forelimb (five medial; seven lateral). All fractures were nonarticular, simple in configuration, and nondisplaced.

Reason for performing study: Analysis was performed to examine a method for refining the preoperative prognosis for horses that had surgery to remove apical fractures of the proximal sesamoid bones (PSBs).

Objectives: To determine if: 1) there was a difference in size or configuration of apical fractures between the different anatomical locations of the PSBs, which have been shown to affect the prognosis; and 2) the size or configuration could predict the prognosis for racehorses with these fractures.

A foal with a cranio-dorsal coxofemoral luxation was treated with a prosthetic capsulorraphy technique after open reduction. After reluxation a femoral head ostectomy was performed for salvage purposes. The filly was discharged with minimal lameness and was using the limb properly after 51 days of hospitalisation. Four years later the filly is still doing well as a breeding mare, with an acceptable quality of life despite angular deformities in the contralateral limb.

Objective—To evaluate the diagnostic features, results of free-choice exercise treatment, prognosis, and postinjury racing performance of Thoroughbred racehorses with cumulative stress-induced bone injury (CSBI) of the distal portion of the third metacarpal and third metatarsal bones (MC3/MT3).

Design—Retrospective case series.

Animals—55 Thoroughbred racehorses with CSBI of the distal portion of MC3/MT3.

Fractures of the pedal bone are usually the result of direct trauma, and are relatively commonly encountered in equine practice. Either front or hind feet may be affected. Seven distinct fracture types are recognised. Type I fractures involve the palmar/plantar process and do not enter the distal interphalangeal (DIP) joint. Type II fractures are oblique or parasagittal fractures that are articular but are not on the midline. Type III fractures are midline articular fractures that bisect the pedal bone into 2 equal halves.

Objective: To report outcome after the surgical treatment of lacerations of the superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), suspensory ligament (SL), and/or distal sesamoidean ligaments (DSL) in horses.

Study Design: Case series.

Animals: Horses (n=106) with lacerations of the SDFT, DDFT, SL, and/or DSL.

Methods: Medical records (1988–2002) were reviewed for signalment, limb and tendon/ligament involvement (location and extent of injury, tendon sheath involvement), method of repair, and outcome.

Reasons for performing the study: A minimally invasive arthroscopic technique for removal of fractures of the lateral malleolus of the tibia is considered to be beneficial but data to this effect are required.
