A technique for digital pad transposition is described and illustrated. This technique has application for use in cases of metacarpal or metatarsal pad neoplasia or severe trauma. The transposed digital pad will provide a weight-bearing surface of heavy, keratinized epidermis in cases where the normal metacarpal or metatarsal footpad has been removed. The use of the technique in four clinical cases of footpad neoplasia also is reported.

Dr Allen L. Hoekman of Harrison, SD, has written as follows: I would appreciate clarification on an inconsistency I've noticed in William Weston's article, "Dermatoses of the Foot" (PIR 1985;7:45). On page 45 and in Table 2, it says that scabies does not involve the plantar surface of the foot. On page 49, it says that scabies can involve the plantar surface (weight-bearing surface). Please clarify. William L. Weston has replied: I agree with Dr Hoekman that it is confusing in the article as to whether or not the weight-bearing surface of the foot is involved in scabies. Clearly, involvement of the weight-bearing surface of the foot in scabies may occur, although the lesions occur predominantly over the dorsum of the foot and extend onto the ankle. For the purposes of making the algorithm in the article work in a simple manner, scabies was placed in this category to help with rapid diagnosis. However, it is clear that scabies can involve the weight-bearing surface of the foot; involvement of this area does not exclude the diagnosis. The algorithm would have perhaps been better if I had included a separate category for involvement of both the sole and the dorsum of the foot, but I believed this would have made the algorithm too complex.

The term 'thin soles' refers to the suboptimal thickness of the weight-bearing surface of claws in ruminants. These palmar / plantar surfaces of the claws support the weight of the animal and consist of the distal wall horn, the sole proper, the heel and the minute white line area. The sole should normally only bear weight on uneven or undulating surfaces. A decrease in the thickness of the weight-bearing claw surface will decrease the protective function of this structure and may alter the proportion of weight-bearing by each section with possible detrimental effects on hoof function. Horn tissue readily absorbs water and becomes softer which can lead to increased wear rates. Growth rates normally match wear rates but, unlike the latter, time is needed for the growth rate response to adapt to changes in wear rate. Concrete surfaces can be abrasive and dairy cows that spend their lactation cycle on these floors should be let out to pasture in the dry period so that their claws can recoup lost horn. Frictional coefficient is a measure of the 'slipperiness' of hooves on various surfaces. Newly laid or fresh concrete is not only abrasive but the thin surface suspension of calcium hydroxide that forms has a very alkaline pH which causes keratin degradation and is mostly responsible for the excessive claw wear that occurs. Four case studies are used to illustrate the importance of the distal wall horn, the dangers of over-trimming and the effects of disease and concrete on horn growth and wear rates.

Mosaic Arthroplasty

One Arabian and 5 Hungarian half-bred horses were used to study the macroscopic and microscopic survival of autologous osteochondral grafts in the weight-bearing surface of the medial femoral condyle (MFC). Grafts were harvested from the cranial surface of the medial femoral trochlea (MFT) under arthroscopic control. Three of them were transplanted into the weight-bearing surface of the contralateral MFC using an arthrotomy approach. Three months later this transplantation procedure was repeated on the opposite stifle joints in the same animals, but at that time transplantation was performed arthroscopically. Follow-up arthroscopy was carried out 12 months after the first operations, and biopsies were taken from both the recipient and the donor sites for histological examination. During follow-up arthroscopy, the transplanted areas looked congruent and smooth. Microscopically, the characteristics of hyaline cartilage were present in 5 out of the 10 biopsies examined; however, in the other half of biopsies glycosaminoglycan (GAG) loss and change in the architecture of the transplanted cartilage was observed. In a 16-year-old horse, all grafts broke during harvesting, and thus transplantation was not performed. No radiological signs of osteoarthritic changes were detected 9 to 12 months after the operations in the donor and recipient joints. Clinically, no lameness or effusion was present three months after the transplantations.

Abstract Background Complications after arthroplasty often result in irreversible disability. In some cases for the extremity to be salvaged, the permanent knee joint arthrodesis is the last-chance procedure. Modular implant design simplifies surgical technique but modularity may potentially compromise mechanical strength of an implant. Mechanical properties of the implant are particularly important in case of knee arthrodesis without bone-on-bone contact where forces during gait and weight bearing are transmitted directly through the nail. The aim of this article was to perform comparative analysis of the mechanical properties of modular nail CHARFIX2 FN, when compared to the femoral nail, used for knee arthrodesis; and to analyze the effectiveness of treatment with use of this nail based on the observations of clinical cases. Methods Comparative analysis of: the static 4-point bending test, dynamic 4-point bending test and static torsion test. All tests were performed in accordance with requirements of ASTM F 1264. A clinical analysis of 5 cases, in which CHARFIX2 FN nails were used, was also performed. Results Based on the results of mechanical tests, the strength characteristics of CHARFIX2 FN nail have been found superior and more advantageous than corresponding features of the standard femoral nail. For CHARFIX2 FN nail, the median for flexural stiffness was almost 4 times higher and for maximum torque value was almost 2 times higher when compared to the femoral nail. Observations of the clinical cases gave satisfactory results. Conclusions The obtained mechanical tests present significant differences between CHARFIX2 FN and the femoral nail in mechanical strength and, therefore, its improved stability and safety for patients during walking. It can be used for permanent knee immobilization with satisfactory clinical results. The functional outcomes and subjective measurements of pain in patients treated with CHARFIX2 FN group are satisfying.

Background: Fractures are a major concern in Veterinary orthopedic surgery because they are often complicated into non unions. The present study was planned to evaluate the fracture healing by using hydroxyapatite-collagen (HAp-Col) as a bone graft substitute and autologous bone marrow concentrate, after the internal fixation by titanium elastic pin. Method: The present work was conducted on 12 clinical cases of dogs having diaphyseal fracture of long bones. In group I (6 animals) fractures were immobilized by an internal fixation technique. In group II fracture was immobilized as in group I with use of autologous bone marrow concentrate along with Hydroxyapatite-collagen at the fracture site. The weight bearing and the progress of fracture healing were recorded. Result: Study showed early weight bearing and no observable lameness in group II as compared to group I animals. Fracture union was earlier and with minimum periosteal callus formation in one animal, five animals at 45 days and 60 days respectively while in group I fracture healing was observed in one animal, two animals at 60 day and 90 days respectively. On basis of result, it is concluded that Hydroxyapatite-collagen composite can be used as along with autolologus bone marrow concentrate as alternative therapy to bone graft in clinical cases to enhance the fracture healing. The use of autogenous and allogenic bone graft having some advantages which is overcome by this present technique.
