Transverse Osteotomy

SummaryA four-month-old Holstein heifer was presented for evaluation of an angular limb deviation. Upon initial presentation, the heifer was not clinically lame. An external rotation of 90° of the fetlock was observed in the left forelimb. Radiographs identified a healing closed spiral fracture of the third and fourth metacarpal bones, with a 90° external torsion. A mid-metacarpal bone transverse osteotomy was performed after insertion of transcortical pins in the distal and proximal part of the third and fourth metacarpal bones and in the distal radius. The reduction was performed in order to align both fetlock and carpal joints and a fiberglass cast was applied to complete the external fixation. A satisfactory outcome was associated with the treatment.

SummaryFifty-two carpal panarthrodeses (CP) were carried out in 44 dogs (eight bilateral), in a multicentre study using a single (n = 47) or double (n = 5) stepped hybrid CP plate. Of these 44 cases, 39 were between 20–55 kg in bodyweight , 26 were males , and the carpometacarpal was the most common joint involved. Falling and other impact trauma were the most common aetiology. Pain of unknown origin, carpal luxation, chronic accessory carpal bone fracture, distal comminuted intra-articular radial fracture, bone tumour, degenerative joint disease, canine erosive idiopathic polyarthritis, avascular necrosis of the radial carpal bone and fractures of several metacarpal bones were some of the pathologies reported. Fracture of the third metacarpal bone during screw insertion was the only intrasurgical complication. Malpositioning of the plate or screws and over-tightened screws were technical errors observed in seven of the procedures. The radial carpal bone was not fixed with a screw in two cases due to bone deformity. Concurrent plate breakage and bending in the same patient operated on bilaterally was observed during the follow-up period, which represented a major complication rate of 3.8% for all procedures. Minor complications were: low grade infection, lick granuloma, digit hyperextension, screw loosening or failure, incomplete fusion of some joints and a fracture of the third metacarpal bone at the distal screw hole of the plate; which represented a rate of 44.2% on all procedures. Complete carpal healing was observed radiographically in 94.2% of all procedures. Limb function was excellent to good, and all of the owners, except for one, were satisfied with the procedure.

SummaryA carpometacarpal hyperextension injury in a cat was treated by pancarpal arthrodesis, following the failure of conservative treatment. An 8-hole 1.5 mm mini plate was placed on the dorsal aspect of the distal radius, carpus and third metacarpal bone. An aluminium spoon splint was used for six weeks postoperatively, until radio-graphs revealed bone union. The body weights and the dimensions of the distal radius, radiocarpal bone and third metacarpal bone from the left limb of 15 cadavers were recorded in order to aid the selection of appropriate implants for future cases.Pancarpal arthrodesis was used to treat a cat with a carpometacarpal hyperextension injury. The use of an 8-hole 1.5 mm mini plate applied to the dorsal surface of the carpus, in combination with limb splinting provided effective stabilization. An excellent functional result was obtained. Measurements of the radius, radial carpal and third metacarpal bones from 15 cadavers suggest that 1.5 mm bone screws are the largest that should be used for carpal arthrodesis in the average sized cat.

Osteosarcoma is the most common primary malignant neoplasm of bones in children; this tumor accounts for 50 to 80% of all skeletal sarcomas. Less often, osteosarcoma affects flat bones (scapula, ribs, bones of the skull and pelvis), bones of the foot, hand and spine. Description of the observation. A 13-year-old girl, 8 months before admission to the clinic, began to complain of pain in her right hand, six months later, a swelling appeared in this area. After radiography, which revealed a bone tumor of the III metacarpal bone, a trepanobiopsy with histological examination was performed. Conclusion: subperiosteal telangiectatic osteosarcoma G II. The child was admitted to the oncology department in November 2018. Before the operation, the girl underwent 4 courses of chemotherapy, as a result of which the tumor reduced in size, which made it possible to perform organ-preserving surgical treatment extirpation of the third metacarpal bone affected by the tumor, followed by autoplasty from the wing of the right iliac bone with fixation of the graft Kirschner needles. The postoperative period passed without complications. As a result of the operation, it was not only possible to radically remove the tumor, but also to preserve 3 fingers of the right (working) hand with good functionality. After surgery, the child received 5 courses of polychemotherapy and is currently in remission. Conclusion. The above observation demonstrates the possibility of performing organ-preserving surgeries using bone autoplasty for rare tumor lesions of the metacarpal bones. This method is more physiological in comparison with the use of allo- or artificial grafts.

Vascularized Bone

The vascular anatomy of the dorsal aspect of the hand is variable. Nevertheless the presence of the first and the second dorsal metacarpal artery (DMA) is constant. DMA3 and 4 are more variable. The anatomical study presented demonstrates the segmental vascularization of the metacarpal bones and the possibility of harvesting metacarpal bone flaps. The reliability of such a flap decreases from the second to the fifth metacarpal bone regarding the frequency of presence of the DMAs. The authors describe six new vascularized bone flaps from the third and the fourth metacarpal bones pedicled on the second or the third dorsal metacarpal artery in an anterograde or retrograde flow mode. This study suggests that the radial and the ulnar side of the third metacarpal bone could be harvested respectively on the DMA2 and DMA3. The radial side of the fourth metacarpal bone could also be a reliable vascularized bone donor site. Flaps can be used proximally or distally based to repair bone defects either on metacarpal and carpal bones or on proximal phalanges.

Metacarpal Bones

The method of determining which animal species the bones, on the basis of mor?phological characteristics, belong to, is one of the most commonly used in forensic cases (poaching, fraud, theft, counterfeiting of food of animal origin).For identification of metacarpal bones (Ossa metacarpi) as well as finger articles (Ossa digitorum pedis seu phalanges digitorum) there were used distal parts of front limb bones, taken from 6 roe deers and 7 sheep. Afer the separation from the soft tissues, the bones were boiled in an autoclave, and for bleaching and degreasing they were kept in 3% solution of hydrogen peroxide (H2O2). The bones were air dried, and then photographed. In roe deer, there are four developed metacarpal bones: the second, the third, the fourth and the fifth. The third and the fourth mrtacarpal bones form one bone, named the main metacarpal bone. The second and the fifth metacarpal bones are connected by con?nective tissue to distal parts of the third and the fourth metacarpal bones. In sheep, there are three developed metacarpal bones: the third, the fourth and the fifth. The thord and the fourth metacarpal bones are, as in roe deer, grown together along the entire length, forming in that way one single bone - the main metacarpal bone. On the distal part of front limb in roe deer there are four fingers, and in sheep two. In roe deer the second, the third, the fourth and the fifth finger are developed, and in sheep, the third and the fourth. Each finger of front limbs, both in roe deer and in sheep, consists of three articles: Phalanx proximalis, Phalanx media i Phalanx distalis. In the case of certain bone missing, a roe deer can be distinguished from a sheep on the basis of the tird article of the third and fourth finger, which is of characteristic appearance. Plantar edge in roe deer is peaked, and in sheep it is blunt. The method of determining which animal species the bones, on the basis of mor?phological characteristics of roe deer and sheep, belong to, is one of the most reliable and most commonly used in forensic cases.

We characterized features of complete diaphyseal fractures of third metacarpal bones in Thoroughbred racehorses. Given that stress fractures are known to occur in the third metacarpal bone, an additional aim was to determine if complete fractures are associated with signs of a preexisting incomplete stress fracture. Bilateral metacarpi from 12 Thoroughbred racehorses euthanized because of complete unilateral metacarpal diaphyseal fracture were examined visually and radiographically. Open, comminuted, transverse or short oblique fractures occurred in the middle of the diaphysis or supracondylar region. Periosteal surface discoloration and bone callus formation contiguous with the fracture line were present in fractured bones. All contralateral intact metacarpi had gross anatomic lesions, and 10 had radiographic abnormalities similar to those observed on fractured metacarpi. Catastrophic metacarpal fractures occurred in racehorses with bilateral evidence of preexisting bone injury.

Introduction: The study compares the results of open reduction using volar locking plates with ligamentotaxis by external fixation in fractures of distal radius type 2R3C according to AO classification. Methods: A retrospective study evaluating the results of osteosynthesis in patients with distal radius fractures type 2R3C according to AO classification, operated until December 2018. The ORIF method with volar locking plates (LCP) was used in 54 patients, and closed reduction with ligamentotaxis using external fixation (EF) was used in 33 patients. The mean age of the patients was 46.7 years in the LCP group and 59.6 years in the EF group. All were evaluated for their X-ray and functional outcomes and according to the Green and O’Brien score at 6 and 12 months after surgery. Results: According to X-rays at 12 months in the LCP group, the mean sagittal tilt was 10.13°, the mean radial inclination was 23.89°, and the mean radial length was 11.84 mm. In the EF group, the mean sagittal tilt was 6.32°, the mean radial inclination was 24.78°, and the mean radial length was 9.89 mm. According to the Green and O’Brien score, we recorded a mean score of 84.44 points in the LCP group at 12 month; we achieved good and excellent results in 83.33% of the patients and no poor result was observed. In the EF group the final mean score was 77.27; good and excellent results were achieved in 45.46% of the patients and a poor result in one patient. Conclusion: Based on the results in our group of patients, the internal type osteosynthesis using LCP implants can be recommended as a first-choice technique in the treatment of 2R3C fractures according to AO classification.

Abstract Introduction Distal radius fractures are common and trends for fixation have changed with increased use of volar locking plates in recent time. A meta-analysis will summarise the best evidence for treatment. Method A systematic review was conducted using PRISMA methodology to identify studies that reported clinical and/or radiological outcomes in patients with AO type C distal radius fractures when treated with external fixation versus ORIF. Results 10 randomised trials were included in this review, reporting on 967 patients. Clinical outcomes are in favour of volar plating at 3 months post-operation, but no difference between the two groups is seen at 6 or 12 months. Analysis of complication rates shows a minute increase in risk-ratio for volar plating versus external fixation. Subgroup analysis showed significantly higher re-operations after plate fixation and significantly higher infection after external fixation. Conclusions Internal fixation of complex distal radius fractures confers an improved clinical outcome at early follow up only and a minimally increased risk of complications. The improved grip strength with volar plating is only superior at early follow up and no long-term superiority is seen with either intervention. The type of surgery in this injury type therefore remains at the surgeon’s consideration on a case-by-case basis.
