Diastrophic dysplasia results in severe disproportionate growth failure, generalized joint dysplasia, and early osteoarthrosis of the hips. A total hip arthroplasty is often necessary in patients afflicted with diastrophic dysplasia by time they reach early middle age. During 1983-1988, total hip arthroplasties were performed on six women and four men (15 hips) with diastrophic dysplasia at the Orthopaedic Hospital of the Invalid Foundation. The mean age of the patients at the time of operation was 37 years and the mean height was 133 cm. A Lord endoprosthesis was used in nine hips and a Biomet endoprosthesis in six. Cementless fixation was used in all cases. Autogenous bone grafting to the acetabulum was performed in six hips. Simultaneous corrective osteotomy of the proximal femur and transposition of the greater trochanter was performed in three cases. Soft tissue release and tenotomies were performed in 10 hips. The average follow-up period was 5 years. Overall clinical results were good, with marked relief of pain and improvement of hip joint mobility. Aseptic loosening of the acetabular component was noted in two hips. As for complications, two femoral nerve paresis and two perioperative fractures of the proximal femur occurred, which all healed.

A patient with long-standing upper limb lower motor neurone paresis more recently developed homolateral upper motor neurone hemiplegia. Subsequent primary generalised osteoarthritis spared only the paralysed upper limb. Detailed review of reported cases suggest that the "protective" effect of paralysis against subsequent development of arthritis is not as clearly established as generally believed.

Osteopetrosis is an inherited skeletal condition characterized by increased bone radiodensity. There are three clinical groups: infantile-malignant autosomal recessive, fatal within the first few years of life (in the absence of effective therapy); intermediate autosomal recessive, appears during the first decade of life but does not follow a malignant course; and autosomal dominant, with full-life expectancy but many orthopaedic problems. The infantile variant shows a myelophthisic anemia, granulocytopenia, and thrombocytopenia, and patients eventually die from infection or bleeding or both. Neurologic sequelae include cranial nerve compression (optic nerve, blindness; auditory nerve, deafness; facial nerve, paresis), hydrocephalus, convulsions, and mental retardation. Radiographs show uniform bone density without corticomedulary demarcation, broadened metaphyses, "bone within a bone" or endobone phenomena (tarsals, carpals, phalanges, vertebra, ilium), and thickened growth plates if there is superimposed rickets. Transverse pathologic fractures occur, often followed by massive periosteal bone formation. Computed tomographic scans, magnetic resonance imaging, and bone scans provide specific information. Iliac crest bone biopsy is valuable to quantitate osteoclast and marrow changes by light and electron microscopy. Medical treatments involve high-dose calcitriol to stimulate osteoclast differentiation and bone marrow transplantation to provide monocytic osteoclast precursors. Orthopaedic problems in the intermediate and autosomal dominant forms include increased fractures, coxa vara, long-bone bowing, hip and knee degenerative arthritis, and mandibular and long-bone osteomyelitis. Cranial nerve compression also occurs. Osteotomy, plating, intramedullary rodding, and joint arthroplasty can be done, but are difficult because of bone hardness.

The results of 15-year own experimental and clinical research on application of variable magnetic fields in medicine were presented. In experimental studies analgesic effect (related to endogenous opioid system and nitrogen oxide activity) and regenerative effect of variable magnetic fields with therapeutical parameters was observed. The influence of this fields on enzymatic and hormonal activity, free oxygen radicals, carbohydrates, protein and lipid metabolism, dielectric and rheological properties of blood as well as behavioural reactions and activity of central dopamine receptor in experimental animals was proved. In clinical studies high therapeutic efficacy of magnetotherapy and magnetostimulation in the treatment of osteoarthrosis, abnormal ossification, osteoporosis, nasosinusitis, multiple sclerosis, Parkinson's disease, spastic paresis, diabetic polyneuropathy and retinopathy, vegetative neurosis, peptic ulcers, colon irritable and trophic ulcers was confirmed.

Young patients with gonarthrosis that does not respond adequately to conservative therapy can be treated by corrective osteotomy. Osteoarthritis of one compartment more often has a mechanical aetiology than osteoarthritis of the entire knee. Patients with osteoarthritis of the medial compartment often have a genu varum (bow-legs) while patients with osteoarthritis of the lateral compartment often have a genu valgum (knock-knees). The goal of corrective osteotomy is to transfer the load bearing to the normal compartment, which will reduce the symptoms and permit arthroplasty to be postponed. In retrospective studies, the procedure resulted in less pain, improved knee function or postponement of knee arthroplasty in 28-87% of the patients. Possible complications include pseudarthrosis, thromboembolism, contracture of the patellar tendon, paresis of the N. peroneus, compartment syndrome. The outcome of osteotomy for gonarthrosis depends on careful patient selection, the stage of osteoarthritis, and the achievement and maintenance of the correction of the load axis that was calculated before the operation.

The aim of this longitudinal observational study was to investigate and describe the spectrum of messenger ribonucleic acid (mRNA) expression of multiple inflammatory markers in circulating leukocytes after major orthopaedic surgery. We studied ten elective arthroplasty patients perioperatively on the orthopaedic ward, and eight healthy volunteers for a comparison group. Venous blood specimens were collected preoperatively, and 6, and 24 hours postoperatively, together with 6- and 24-hour postoperative wound drain specimens. The mRNA of 21 different inflammatory mediators was measured by real-time reverse transcriptase Polymerase Chain Reaction. Comparisons were made with the venous blood of eight healthy comparison subjects. There were significant differences (P<0.01) between preoperative specimens and normal comparisons (i.e. higher MPO, PDGF, TREM and IRAKM; lower mtHSP) reflecting the effects of chronic inflammation associated with osteoarthritis. There were significant increases (P<0.01) in expression of IL-8, MPO, IL-1beta, TREM, MMP9, and C5aR in circulating blood at 24 hours postoperatively, but not at six hours. There was no significant decrease in expression of any inflammatory mediator. There was no statistical difference in inflammatory mediator expression between drain specimens and venous specimens taken at the same time. We conclude that, in uncomplicated orthopaedic surgical patients, there was up-regulation of some cytokine mRNAs at both the local and systemic levels during the first day after surgery. We observed no evidence of immune compartmentalization, and found no evidence for innate immune paresis within the first day after surgery.

The purpose of this study was to analyse the intermediate-term results of an arthroscopic procedure to debride and resurface the arthritic glenoid, in a middle-aged population, using an acellular human dermal scaffold. Between 2003 and 2005, thirty-two consecutive patients underwent an arthroscopic debridement and biological glenoid resurfacing for glenohumeral arthritis. The diagnoses included primary osteoarthrosis (28 patients), arthritis after arthroscopic reconstruction for anterior instability (1 patient) and inflammatory arthritis (3 patients). All shoulders were assessed clinically using the Constant and Murley score, and results graded according to Neer's criteria. Statistical analysis was performed to determine significant parameters and associations. A significant improvement (P < 0.0001) in each parameter of the subjective evaluation component (severity of pain, limitation in daily living and recreational activities) of the Constant score was observed. The Constant and Murley score increased significantly (P < 0.0001) from a median of 40 points (range 26-63) pre-operatively to 64.5 (range 19-84) at the final assessment. Overall, the procedure was considered as "successful outcome" in 23 patients (72%) and as a "failure" in 9 patients (28%). According to Neer's criteria, the result was categorized as excellent in 9 (28%), satisfactory in 14 (44%) and unsatisfactory in 9 (28%). Within the unsatisfactory group, there were five conversions to prosthetic arthroplasty. A standard magnetic resonance imaging was performed on 22 patients in the successful outcome group; glenoid cartilage was identified in 12 (thick in 5, intermediate in 1, thin in 6) and could not be identified in 10 patients (complete/incomplete loss in 5, technical difficulties in 5). Overall, five complications included transient axillary nerve paresis, foreign-body reaction to biological material, inter-layer dissociation, mild chronic non-specific synovitis and post-traumatic contusion. Dominance of affected extremity and generalized disease (diabetes, rheumatoid arthritis, generalized osteoarthritis) was associated with an unsatisfactory outcome (P < 0.05). Arthroscopic debridement and biological resurfacing of the glenoid is a minimally invasive therapeutic option for pain relief, functional improvement and patient satisfaction, in glenohumeral osteoarthritis, in the intermediate-term.

A 3-year-old Thoroughbred gelding presented with a history of neurological signs, including incoordination in his hindlimbs, of about 7 months' duration. On initial examination, the horse exhibited ataxia and paresis in all limbs with more severe deficits in the hindlimbs. Cervical radiographs displayed severe osteoarthritis of the articular processes between C5 and C6. On subsequent cervical myelography the dorsal contrast column was reduced by 90% at the level of the intervertebral space between C5 and C6. Cervical vertebral canal endoscopy, including epidural (epiduroscopy) and subarachnoid endoscopy (myeloscopy), was performed under general anaesthesia. A substantial narrowing of the subarachnoid space at the level between C6 and C7 was seen during myeloscopy, while no compression was apparent between C5 and C6. Epiduroscopy showed no abnormalities. After completion of the procedure, the horse was subjected to euthanasia and the cervical spinal cord submitted for histopathological examination. Severe myelin and axon degeneration of the white matter was diagnosed at the level of the intervertebral space between C6 and C7, with Wallerian degeneration cranially and caudally, indicating chronic spinal cord compression at this site. Myeloscopy was successfully used to identify the site of spinal cord compression in a horse with cervical vertebral stenotic myelopathy, while myelography results were misleading.

Two boa constrictors (Boa constrictor imperator) presented with paresis of the trunk originating cranial to the cloaca. Radiographs were consistent with proliferative bone lesions involving several vertebrae. Computed tomography (CT) demonstrated the presence of lytic/expansile lesions. Computed tomography-guided biopsies of the lesions were performed without complications. Histology was consistent with bacterial osteomyelitis and osteoarthritis. Gram-negative bacteria (Salmonella sp. and Pseudomonas sp.) were isolated from cultures of the biopsies. Medical treatment with specific antibiotics was attempted for several weeks in both cases without clinical or radiographic improvements. The animals were euthanized, and necropsy confirmed the findings observed upon CT. To the authors' knowledge, this is the first report of the use of CT-guided biopsies to evaluate proliferative vertebral lesions in snakes. In the present report, CT-guided biopsies were easily performed, and both histologic and microbiologic results were consistent with the final diagnosis.

Two Livingstone's fruit bats (Pteropus livingstonii) presented with a unilateral partial paresis of the hind limbs. Radiographs revealed luxation of the coxofemoral joint and degenerative joint disease in the right coxofemoral joint in one case. The second case presented with recurrent luxation of the coxofemoral joint with osteoarthrosis of the femoral head. Clinical findings in both cases led to a decision to perform a femoral head resection. The performed surgery led to the recovery of normal function of the limb without any complications in both cases.
