This study involves the evaluation of pre-purchase radiographic studies of South African Thoroughbred yearlings. Radiographic changes were recorded and compared with similar international studies. The study differs from other studies in that a lower prevalence of pedal osteitis (1.26 %), dorsal osteochondral fragmentation of the metatarsophalangeal joint (1.60 %), distal metacarpal sagittal ridge changes (15.7 %), ulnar carpal bone lucencies (8.33 %), carpal osteophytes (1.19 %), distal intertarsal and tarsometatarsal joint radiographic changes (9.92 %), tarsal osteochondrosis lesions (4.40 %) and stifle osteochondrosis lesions (0.4 %) was found. The prevalence of dorsal osteochondral fragments in the metacarpophalangeal joint was similar to other studies (1.60 %). A higher prevalence of vascular channels as well as irregular borders and lucencies was evident in the proximal sesamoid bones. There was a higher prevalence of palmar metacarpophalangeal and plantar metatarsophalangeal osteochondral fragments (2 % and 7.10 % respectively). Palmar metacarpal disease, metacarpal supracondylar lysis, proximal sesamoid bone fractures and carpal osteochondral fragmentation were absent in the current study. Additional findings recorded in the current study were proximal interphalangeal joint hyperextension (left front 15.13 %, right front 18.91 %), the solar angle (right front 2.38°, left front 2.79°), the prevalence of carpal bone 1 (30.95 %) and carpal bone 5 (1.59 %). Management, nutrition and genetics in the various groups of Thoroughbred yearlings should be further investigated in order to explain the reasons for the differences recorded in the current study.

SummaryLameness associated with carpal varus deformity was recognised in 10 dogs, eight of which were Dobermann Pinschers. The dogs had a mean age of seven years and nine months. Carpal varus was usually bilateral with concurrent carpal hyperflexion and pronation. Carpal varus was present prior to the onset of lameness in four cases. With stress radiography the median angle of varus deviation in all carpi was 14.6°, and an increase in the size of the ulnar /ulnar carpal bone joint space was seen in six of the seven dogs. Radiographic changes included: enthesophyte formation at the proximolateral aspect of metacarpal V, periarticular soft tissue swelling, especially lateral, bone proliferation at the carpometacarpal joint I and enthesophyte formation at metacarpophalangeal joint V. Four dogs were admitted for problems other than carpal varus and lameness was not treated. Five dogs were treated with nonsteroidal anti-inflammatory drugs, but lameness was not completely resolved and became exacerbated with exercise. One dog was successfully treated by pancarpal arthrodesis.

A five-year-old Holstein bull became lame after dismount during semen collection. Swelling of the pastern of the left front limb was noted. Radiographic images showed biaxial hyperflexion of the proximal interphalangeal joints in digits III/IV without hyperextension of the metacarpophalangeal joint. Conservative management (stall confinement and NSAIDs) failed to resolve the lameness. External coaptation to stabilise the joint failed to prevent hyperflexion of the joint within the cast and to improve comfort. Pressure sores developed after seven days. Surgical arthrodesis of the PIP joint was performed on each digit by application of a locking compression plate. The bull healed and arthrodesis of the joints progressed over the next 16 weeks. At that time, the bull was walking sound and was returned to semen collection. One year after surgery, the attending veterinarian reported that the bull remained sound at a walk and was still being used for semen collection.

This review describes the different possibilities for arthroplasties at the proximal interphalangeal joint, thumb carpometacarpal joint, distal radioulnar joint, metacarpophalangeal joint and the wrist. For each joint, the indication for arthroplasty is explained, the surgical technique with the suitable implant is described and a brief summary of the outcomes reported in the literature is given.

Twenty seven opponensplasties for ulnar and median paralysis in 25 leprosy patients were performed using extensor indicis proprius. An additional transfer of the radial half of flexor pollicis longus to extensor pollicis longus was done to stabilize the metacarpophalangeal joint of the thumb. The biomechanical aspects of extensor indicis proprius tendon transfer were studied and results evaluated using various anatomical and functional parameters. Extensor indicis proprius provides adequate strength to position the thumb. However, sometimes it does not reach its new insertion. There is no significant deficit at the donor site but in a few cases the index finger may lose its capability for independent extension and sometimes a proximal interphalangeal joint contracture may develop.

Several surgical options have been described to manage persistent dorsiflexion contracture at the metatarsophalangeal joint and plantarflexion contracture at the proximal interphalangeal joint of the fifth toe. We describe a minimally invasive technique for the management of this deformity. We perform a plantar closing wedge osteotomy of the 5th toe at the base of its proximal phalanx associated with a lateral condylectomy of the head of the proximal phalanx and at the base of the middle phalanx. Lastly, a complete tenotomy of the deep and superficial flexor tendons and of the tendon of the extensor digitorum longus is undertaken. Correction of cock-up fifth toe deformity is achieved using a minimally invasive approach.

South Africa's emergence from years of political and regulatory trade barriers has focussed attention on South African exporters. In a replication of Elliot Krasnostein's study of 54 Singaporean exporters, the perceptions, attitudes and characteristics of a representative sample of 321 experienced South African exporters and their decision makers were investigated. Consistent with other international studies, the results suggest that managerial, organizational and environmental forces and perceptions motivate export behaviour. However, South African firms clearly are responding to unique situational factors and national export resources as well. The findings indicate that managerial leadership, supportive attitudes and extensive exporting experience are widely available in South Africa. Secondary information sources could be improved and freight costs reduced to improve South African export effectiveness.

Background: Lesser toe surgery is among the most conducted interventions in general orthopedic practice. However, the definitions of hammer toe and claw toe are not uniform. The objective of this literature study is to propose clear definitions for these deformities to establish unambiguous communication. Methods: A literature search was performed in the PubMed database (May 2006). Of 81 eligible articles, 42 that stated a clear definition of hammer toe or claw toe were selected. Results: In all 35 articles in which hammer toe was clearly defined, flexion in the proximal interphalangeal joint was part of the definition. Seventeen articles (49%) defined hammer toe as a combination of metatarsophalangeal extension and proximal interphalangeal flexion. Thirteen articles showed flexion of the proximal interphalangeal joint as the single criterion. Twenty-three articles with a clear definition of claw toe were selected. Twenty-one articles (91%) showed metatarsophalangeal extension as part of the claw toe deformity. Twelve articles (52%) regarded metatarsophalangeal extension and flexion of the proximal interphalangeal and distal interphalangeal joints as the essential characteristics. Seven articles described a claw toe as metatarsophalangeal extension with flexion in the proximal interphalangeal joint. Conclusions: There are variations in the definitions of lesser toe deformities in the literature. We propose that extension of the metatarsophalangeal joint is the discriminating factor and essential characteristic for claw toe. Claw toe and hammer toe should be characterized by flexion in the proximal interphalangeal joint, which is the single criterion for a hammer toe. The flexibility of these joints could be a basic factor in discriminating between these deformities. The development of these deformities should be regarded as a continuum in the same pathophysiologic process. (J Am Podiatr Med Assoc 99(3): 194–197, 2009)

In 2016, our primary modality for radiological examination of wrist trauma, was changed from radiography to cone-beam computed tomography (CBCT). This is a retrospective survey of carpal bone fractures detected by CBCT during 6 months in 2016/2017, compared with those found on conventional radiographs during 6 months in 2013/2014. The incidence of carpal fractures was three times higher during the CBCT period (92/100,000 per year) compared with the radiography period (29/100,000 per year) and the spectrum of anatomical locations was different between the two periods, with fractures of the lunate ( n = 6), trapezium ( n = 9), trapezoid ( n = 4) and capitate ( n = 1) detected by CBCT, in contrast to no fractures of these bones diagnosed during the 6 months radiography period. We suggest a more liberal use of CBCT for examination of wrist trauma considering the benefits of being able to give patients a correct primary diagnosis, treatment and prognosis. Level of evidence: III
