“…Release of the latter has been suggested in cases of tenosynovitis in order to limit the potential for carpal tunnel syndrome (Nixon 2002;McIlwraith et al 2005). None of the horses reported in the current series exhibited evidence of carpal tunnel syndrome (Textor et al 2003;Bland 2007;Byron et al 2010); the carpal flexor retinaculum was therefore left intact. In the current cases, disrupted tendon tissue was removed using similar techniques and rationale to other synovial locations (Wright and McMahon 1999;Minshall and Wright 2006;Smith and Wright 2006;Smith et al 2007).…”

“…In light of these findings, retinacular thickening is likely a consequence, rather than a cause of carpal sheath effusion. Surgical intervention to resolve retinacular thickening and carpal canal compression does provide immediate relief in most cases; however, the primary lesions within the carpal sheath structures could result in persistence or recurrence of clinical signs in the longer term.…”

“…Thickening of the carpal flexor retinaculum has also been described in conjunction with lesions in adjacent structures . Retinacular thickening exacerbates the constriction of soft tissue structures enclosed within the carpal canal and can generate a condition analogous to Carpal Canal Syndrome in people as a consequence of direct compression of the medial palmar artery and/or nerve …”

Equine carpal sheath effusion has multiple etiologies. The purpose of this retrospective study was to describe the prevalence of distinct musculoskeletal lesions lameness in a sample of horses with a clinical diagnosis of carpal sheath effusion. A total of 121 horses met inclusion criteria. Seventy-four percent (89/121) of horses were lame at presentation; middle-aged (9-18 years, 80%) and older (> 18 years, 85%) horses were lame more frequently than young horses (< 9 years, 44%). Ninety-three percent (113/121) were diagnosed with osseous and/or soft tissue abnormalities. Of these 113 horses, 10 exhibited osseous abnormalities, whereas 111 were diagnosed with soft tissue lesions. Eighty-four percent (93/111) of the soft tissue injuries extended from the caudodistal antebrachium to the palmar metacarpus. The superficial digital flexor tendon (98/111; 88%) and accessory ligament of the superficial digital flexor tendon (64/111; 58%) were the most commonly injured structures, with both structures affected in 41 (41/111; 37%) horses. Injuries within the caudodistal antebrachium included the superficial digital flexor musculotendinous junction (66), the accessory ligament of the superficial digital flexor tendon (64), and deep digital flexor muscle (21), in isolation or in combination with other structures. Increased echogenicity in the medial superficial digital flexor musculotendinous junction was detected in 40 horses and was significantly associated with increasing age (middle-aged, 19/40; old, 18/40). Findings from this study indicated that age should be taken into consideration for horses presented with carpal sheath effusion and that adjacent structures within the caudodistal antebrachium should be included in evaluations.

“…Prolonged inflammation within the carpal sheath can result in "carpal canal syndrome," a painful entrapment neuropathy that results from chronic effusion, whether the result of sepsis or trauma associated with distal radial osteochondromata, caudal radial physeal exostoses, carpal hyperextension injuries (with or without accessory carpal bone fractures), and injuries of the superficial or deep digital flexor tendons. 17…”

A diagnostic pathologist’s guide to carpal disease in racehorses

As a pathologist, postmortem examination of the equine carpus can be daunting. The anatomy is complex and oftentimes, small or subtle lesions have significant impact on lameness and secondary lesions such as catastrophic musculoskeletal fractures and other injuries. In performance horses, particularly racehorses, the carpus is a common site of injury and source of lameness. Given the predisposition of racehorses to developing carpal disease, familiarity with clinically relevant anatomy and common developmental, degenerative, traumatic, and inflammatory processes are imperative for thorough postmortem examination. Our aim is (1) to provide a concise summary of clinically relevant anatomy and function that serves as a guide for postmortem evaluation of the equine carpus, and (2) to review common carpal injuries and diseases in actively training, racing, or retired racehorses, including developmental lesions (incomplete ossification, osteochondromata), infectious and inflammatory lesions (septic arthritis and tenosynovitis), and degenerative and traumatic lesions (degenerative and traumatic osteoarthritis, osteochondral fragmentation, and polyostotic catastrophic "breakdown" fractures). Representative gross and histologic images are presented along with corresponding antemortem and postmortem diagnostic images, and a review of current scientific literature pertaining to the pathogenesis of these equine carpal lesions.

Modified Tenoscopic Method for Carpal Flexor Retinaculum Release in a Horse

Abstract: The distolateral instrument portal described may be a useful alternative to a proximolateral portal when distal carpal sheath instrument access is necessary or advantageous.
