Summary
Reasons for performing study

Osteochondritis dissecans (OCD) of the distal sagittal ridge of the third metacarpal bone (McIII) has not previously been described in the literature.
Objectives

To describe the clinical, radiological and arthroscopic features of OCD of the distal sagittal ridge of the McIII and to report outcome in a series of cases.
Study design

Retrospective case series.

Summary Reasons for performing study Accurate radiological and ultrasonographic descriptions of frontal plane fractures of the accessory carpal bone (ACB) are lacking, and implications of these fractures for the carpal sheath and its contents have not previously been reported.

A 9-year-old Paint pony gelding presented for signs of left carpal swelling of 1–2 weeks' duration. Radiographic, ultrasonographic and arthroscopic evaluation of the left carpus was consistent with synovial osteochondromatosis. This presumptive clinical diagnosis was confirmed histopathologically. Arthroscopic removal of the osteochondral bodies resulted in resolution of the carpal effusion and return to previous athletic activity by 4.5 months post operatively. Arthroscopic removal of osteochondral bodies is the treatment of choice in cases of suspected synovial osteochondromatosis.

Summary
Reasons for performing study

The factors associated with outcome following solar foot penetration involving synovial structures treated using endoscopic lavage have not been described in the UK population.
Objectives

To provide descriptive data on horses with synovial contamination or sepsis following solar penetration in 4 UK equine referral hospitals and to identify specific factors associated with the outcome.
Study design

Retrospective case series.

Reason for performing study

Although arthropathy of the cervical articular process joints (APJs) is common, descriptions of the arthroscopic technique of the cervical APJ have not been reported previously.
Objectives

To develop an arthroscopic approach to the APJ and to describe the arthroscopic anatomy of the APJ.
Study design

Descriptive cadaver study and clinical case report.

This article describes diagnostic arthroscopy and arthroscopic management of selected lesions in the standing equine patient. Details on case selection, patient and operating room preparation, and surgical technique are presented. This information will add techniques that avoid general anesthesia to the equine surgeon’s armamentarium.

Objective

To assess use of an 18 g arthroscope for diagnostic stifle joint examination in the standing horse.
Study Design

Phase 1 used cadaver limbs and simultaneous ultrasonographic assessment. Phase 2 used 6 normal horses where stifles were assessed in both a standing and flexed position. Phase 3 used horses with suspected stifle injury or disease.
Animals

Normal horses (n = 6) to assess ability to perform diagnostic procedure (phase 2) and 3 clinical cases (phase 3).

Arthroscopy enables direct inspection of the articular surface, but provides no information on deeper cartilage layers. Optical coherence tomography (OCT), based on measurement of reflection and backscattering of light, is a diagnostic technique used in cardiovascular surgery and ophthalmology. It provides cross-sectional images at resolutions comparable to that of low-power microscopy. The aim of this study was to determine if OCT is feasible for advanced clinical assessment of lesions in equine articular cartilage during diagnostic arthroscopy.

Reasons for performing the study

Intra-articular soft tissue injuries of the equine tarsocrural joint have been poorly defined.
Methods

All horses that underwent arthroscopic surgery of a tarsocrural joint over a 10 year period were identified. Those with primary intra-articular soft tissue injuries were selected for inclusion and the cases evaluated retrospectively.

Abstract Objective To describe the arthroscopically accessible anatomy of the tarsal collateral ligaments in the horse. Study Design Descriptive study. Animals Cadaveric equine hind limbs (n = 24) obtained from horses without tarsal disease. Methods Two pairs of tarsal joints were used to obtain silicone models of the tarsocrural joint and dissect the tarsal collateral ligaments (CLs). Ten pairs of tarsocrural joints had arthroscopic exploration and the accessible parts of the tarsal CLs were marked with an arthroscopic hook knife.
