Quantitative assessment of weight-bearing feet reaction at walking (computer complex DiaSled-Scan, St.Petersberg) was performed in 6 patients with pelvic bone fractures treated by transosseous osteosynthesis using Ilizarov device. In stable fixation of pelvic bones by the device the forefoot was used as additional balance when walking without assistive devices. The decrease in anterior and posterior push range which is compensated by the increase in time during one cycle of gait and its' variability should be considered as a summarizing index of adaptive changes of gait. Compensatory increase up to 40% of stance phase variability on the less involved side is preserved by 1 year after surgery.

The Subject

Objective The aim of this study was to evaluate epoxy-pin external skeletal fixation technique for the treatment of open fractures in calves and foals. Study Design Twenty-eight calves and four foals (weighing 45–105 kg) with fractures distal to the stifle or elbow made the subject for the retrospective study. The pins (2.0–3.0-mm Kirschner wires, crossed at 60–90°) were fixed at least at two locations in both proximal and distal bone fragments as per the case situation. The pins in the same plane were bent (∼2 cm from the skin) towards the fracture site or joint and were joined using an adhesive tape (additional pins used when required) to make a temporary scaffold of connecting bars or rings. Thoroughly mixed epoxy putty was applied along the pin scaffold (the epoxy columns were 20–25 mm diameter) and allowed to set for 45 to 60 minutes. All animals were evaluated based on various clinical and radiographic observations made at regular intervals. Results The epoxy-pin fixation was easy to apply and provided stable fixation of bone as indicated by early weight bearing, and fracture healing within 45 to 60 days (17/32 cases). The functional recovery was good to very good in 14 animals and satisfactory in nine cases by 12 months after removal of the fixator. Conclusions The multiplanar epoxy-pin external skeletal fixation provides stable fixation of unstable open fractures distal to the stifle or elbow joint; hence, it can be used to treat a variety of fractures in calves and foals weighing up to approximately 100 kg, especially open infected fractures of lower limb, which are difficult to treat by conventional techniques.

Clinical assessment of fracture healing is usually subjective, relying upon the detection of movement (‘feel’) by the surgeon, the patient’s response in terms of pain and confidence, and radiographic evidence of callus and primary bone union. A more quantitative, objective method of measuring the strength of a healing callus would be useful in assessing many aspects, such as the effectiveness of different forms of treatment, the pattern and rate of healing, and the stage at which the patient can return to full weight-bearing activity. The results presented in this paper demonstrate the complexity of monitoring fracture healing in leg stance phase using an instrumented intramedullary (IM) nail equipped with a single sensor. The bone healers exhibited both sigmoidal and linear load responses during fracture healing. Ambulating non-healers demonstrated high nail forces which did not change significantly over time whereas lame non-healers demonstrated a decreasing nail load due to reduced GRF or loosening of fixation.

The authors present their experience in the application of external fixation devices for the treatment of 96 patients with multiple and combined pelvic bones injuries. It is shown that treatment with use of both pivot and pin devices exerts powerful antishock effect, allows to shorten the duration of bed rest and early activate the patient. Favourable results were achieved in all cases.

Design: Study on the cases of the united interlocked intramedullary (IM) nailed humeral shaft fractures. Objective: To assess the healing pattern of nailed humeral shaft fracture and to compare it with the results of the other previous authors’ nail-treated large bone fractures. Background data: Based on the relevant previous studies related with healing patterns of the interlocked IM nail-managed humeral shaft fractures, the current age-matched study on the participating callus for union was conceived. The comparative study on the healing patterns between the fractures of non-weight-bearing long bone — the humerus — and other large weight-bearing long bones have never been carried out previously. Materials and methods: Eighty-nine cases of the humeral shaft fractures, fixated with antegrade interlocked IM standard Kuentscher nail were subjected to the study. The patients’ ages ranged from the late teens to 9th decade of life. For the antegrade nailing, two entry points were chosen; conventional entry point in the early series, and rotator cuff interval in the late series. Results: External callus was very rarely formed [12 cases (13.4%)]. It was formed at post-fixation 6.5 weeks on average in cases with unreduced displaced fragment, and proximal interlocking. Radiographic union occurred at post-fixation 17.6 weeks on an average by primary osteonal callus. Conclusion: It was concluded that in most cases union was obtained primarily by the contact or gap healing irrespective of the patients’ ages, and that periosteal participation was very rare or negligible. Use of smaller diameter nail or new development of less rigid IM nail without external nail shape change is thought desirable to induce periosteal callus in early healing stage.

Background: Radius-ulna is the most frequently fractured bone of the pectoral limb in dogs with high predisposition to distal fractures. The smaller size of the distal fragment and open physis restrict the use of rigid fracture fixation techniques in distal fractures of growing dogs. Titanium elastic nails (TENs) are recommended in medical practice to stabilize long bone fractures in children. There is paucity of literature on TENs for the repair of radius-ulna fractures in dogs. Methods: This clinical study enrolled 10 dogs (7 grey hound and one each of Crossbred, Pomerenarian and Siberian Husky) suffering from distal radius-ulna (6 transverse and 4 short oblique) fractures since a mean ± SD duration of 3.40±4.5 days. The mean ± SD age and body weight of the dogs was 12.60±6.45 months and 14.09±6.41 Kg, respectively. All except one fracture was stabilized with two TENs inserted into the medullary canal of radial bone in a normograde manner from distal to proximal end using open cranio-lateral surgical approach. Result: Majority fractures achieved satisfactory reduction (n=8), radiographically. Weight bearing scores on walking increased gradually from day 12 (1.62 ± 1.51) to 45th (2.57±1.51), day 60th (3.75±0.5) and day 90 (4.0±0). Five dogs had uneventful recovery whereas remaining had major (n=2) or minor (n=3) complications. The length of the operated bone was non-significantly lesser as compared to contralateral healthy bone on day 60. Goniometric assessment of carpal joint of operated limb showed restricted range of motion on day 12 that improved to the near normal as contralateral healthy limb on day 60. Long-term results showed full (9) and acceptable (1) functional outcome. In conclusions, the TENs technique is simple and less invasive alternative fixation technique for distal radius-ulna fractures in young and light weighing dogs. As per authors, this is the first report on the use of TENs for the management of radius-ulna fracture in dogs.

In Pregnancy

Albeit rare, the majority of identified bone lesions in pregnancy spare the pelvis. Once encountered with a pelvic bone lesion in pregnancy, the obstetrician may face a challenging situation as it is difficult to determine and predict the effects that labor and parturition impart on the pelvic bones. Bone changes and pelvic bone fractures have been well documented during childbirth. The data regarding clinical outcomes and management of pregnancies complicated by pelvic ABCs is scant. Highly suspected to represent an aneurysmal bone cyst, the clinical evaluation of a pelvic lesion in the ilium of a pregnant individual is presented, and modes of delivery in such a scenario are discussed.
