The strength of the Scarf osteotomy has been compared to that of other metatarsal osteotomies, but the effect of increasing the amount of displacement is unknown. The purpose of this study was to determine whether increasing offset adversly affects the strength of the Scarf osteotomy.
Seven pairs of freah frozen cadaveric feet were tested. Specimens in Group 1 underwent Scarf osteotomy with displacement of one third the mid shaft diameter. Specimens in Group 2 were offset two thirds the midshaft diameter. All osteotomies were fixed using two Barouk screws. Each specimen was tested in cantilever bending using a servohydraulic testing machine.
There was no statistically significant difference in strength or stiffness between the two groups. Mean strength was 75.2 N ± 16.8 for Group 1 and 64.8 N ± 28.7 for Group 2 (p>
0.05). Mean stiffness was 12.9 N/mm ± 5.1 for Group I and 10.2 N/mm ± 5.9 for Group 2 (p>
0.05).
All specimens failed at the proximal extent of the osteotomy. Failure did not occur by screw pullout in either Group. The proximal part of the cut is therefore the weakest part of the construct irrespective of the degree of osteotomy displacement.
Hallux rigidus is the second most common pathological condition of the first metatarsophalangeal joint, after hallux valgus. Manipulation of the joint and injection with steroid and local anaesthetic (MUA and Injection) is widely practiced, but the literature contains little information on the results of such treatment. We report the results of this procedure performed on thirty-seven joints, with a minimum follow-up of 1 year (mean 41.2 months). Patients with mild (Grade I) changes gained symptomatic relief for a mean of 6 months and only one third required further surgery. Two thirds of patients with moderate (Grade II) disease proceeded to open surgery. In advanced (Grade III) hallux rigidus little symptomatic relief was obtained and all patients required operative treatment. We recommend that joints are Graded before treatment and that MUA and injection be used only in early (Grades I and II) hallux rigidus.
To investigate the incidence of complications arising from clavicle fractures in children and the need for multiple review in fracture clinic.
Retrospective analysis of 200 children with isolated clavicle fractures. The number of clinic visits was documented along with the mechanism of injury and any complications attributable to the fracture. Plain radiographs allowed classification of the fractures both in terms of site and type of fracture. Prospective analysis of 60 children with isolated clavicle fractures. All patients were discharged with a patient information sheet after their first fracture clinic appointment and were reviewed a minimum of 6 months post injury to assess clinical outcome/complications and patient satisfaction. Retrospective review failed to provide any evidence of long term complications from isolated clavicle fractures. Two patients complained of a non-specific tingling in the arm which had settled within 2 weeks. No intervention other than rest in a broad arm sling was deemed necessary in any of the 200 children. Despite this, the average number of clinic appointments was 2.8. In the prospective study there were no complications arising from an isolated clavicle fracture. Two patients returned (one at 6 weeks and one at 12 weeks) with concerns about the cosmetic appearance of the fracture site - both patients were reassured and discharged. All patients were satisfied with the cosmetic appearance and function of their shoulder when reviewed at a mean of 7.3 months post injury (range 6–10 months). All patients and/or guardians were satisfied with the patient information sheet. Isolated clavicle fractures in children are rarely complicated by injuries such as skin necrosis or a neuro-vascular deficit. Despite this, children are commonly reviewed many times by juniors in a busy fracture clinic. We suggest that such review is unnecessary and that uncomplicated fractures may be safely discharged with a patient information sheet after the first clinic appointment.
The use of a forearm cast for paediatric buckle fractures of the distal radius is widespread practice. These fractures do not displace and follow-up in Fracture Clinic is only for cast removal. This may mean missed school for the child, or work for parents. Modern materials allow a robust lightweight back-slab to be used for protection of these stable, though painful, injuries. Unlike a plaster of Paris backslab, Prelude? (Smith and Nephew) is removed by unwrapping the outer bandage. Parents can do this at home. We prospectively studied 41 consecutive children aged 12 or less with buckle fractures of the distal radius, presenting to Fracture Clinic. After the diagnosis of isolated buckle fracture was confirmed, a Prelude? cast was applied. Parents were given a full explanation and written instructions, which were also sent to the GP. Telephone follow-up was carried out at 3–4 weeks. Forty of forty-one parents expressed satisfaction with both the treatment and the instructions. The parents of one patient misunderstood the instructions, re-presented to fracture clinic and were dissatisfied for this reason. With modern casting materials and adequate instructions at Fracture Clinic, routine follow-up of patients with buckle fractures is unnecessary. Resource savings can be made in this way with no compromise to patient care and increased patient/ parent satisfaction.
