We investigated whether, in the management of stable paediatric fractures of the forearm, flexible casts that can be removed at home are as clinically effective, cost-effective and acceptable to both patient and parent as management using a cast conventionally removed in hospital. A single-centre randomised controlled trial was performed on 317 children with a mean age of 9.3 years (2 to 16). No significant differences were seen in the change in Childhood Health Assessment Questionnaire index score (p = 0.10) or EuroQol 5-Dimensions domain scores between the two groups one week after removal of the cast or the absolute scores at six months. There was a significantly lower overall median treatment cost in the group whose casts were removed at home (£150.88 (sem 1.90) vs £251.62 (sem 2.68); p <  0.001). No difference was seen in satisfaction between the two groups (p = 0.48).

Impaired vascularity of the skin in elderly ankle fracture patients causes the skin and wound complications. This is part of a RCT comparing ORIF and close contact casting (CCC) for isolated unstable ankle fractures in patients > 60 years. Assessments over 6-months

trans-cutaneous O2 saturation (TcP02) of medial and lateral ankle skin

Ankle-Brachial Pressure Index (ABPI).

3-vessel arterial duplex scan

distal calf perforator artery patency.

The uninjured limb was the control.

Eighty-nine patients eligible; 59 participated (76% female). 30 randomised to ORIF; 29 to CCC. Each had one death and one withdrawal. Vascular data available on 55. Two patients had delays in wound healing (> 25% for > 6-weeks). Two further developed wound infections. No skin breakdowns in CCC group. There was a reduced TcP02 on day-3 in the injured limb. The TcP02 rose at 6-weeks compared to day-3 (medial 58mmHg; lateral 53mmHg, p=0.002) in the injured leg. At 6-months the TcP02 measurements were not different to uninjured leg. A critical TcP02 (< 20mmHg) found in 4, correlated with skin problems (p=0.003). Two of these had the only major delays in wound healing and one of the two wound infections.

94% of participants had normal ABPI’s (> 1.0). There was no difference between patients with or without an impaired ABPI (< 0.7 mm Hg) and wound problems (p=0.20).

There was no difference in patent perforators between the injured and uninjured (p=0.39).

Occult vascular insufficiency is present but at low incidence. ABPI and Duplex-US are insensitive for predicting infection or delayed healing. The ankle fracture injury does not disrupt the local perforators. TcPO2 is sensitive and specific for predicting skin problems. Impairment of skin oxygenation is transient. Current TcPO2 technology however is impractical as a clinical tool.

The purpose of this study was to investigate the use of early post-operative bone scintigraphy to predict surgical outcome following vascularized fibular grafting (VFG) for osteonecrosis of the hip. Bone scans from one hundred and four hips (Steinberg stage I–IV) treated with VFG between 1994 and 2000 were retrospectively reviewed. Bone scan scores were significantly lower in the failed group (n=31) compared to the successful group (n=73), p=0.03. Logistic regression demonstrated that a higher bone scan score was associated with success, p=0.028, with an odds ratio of 3.08 (1.13–8.40).

The purpose of this study was to investigate the use of bone scintigraphy to predict surgical outcome following vascularized fibular grafting (VFG) for osteonecrosis of the hip.

Subjects with a higher bone scan score post-operatively had a three-fold higher chance of success than subjects with the lowest score.

These results suggest that having a well perfused and viable graft in the early post-operative period improves the chances of a successful result.

Single Photon Emission Computed Tomography images from one hundred and four hips (Steinberg I–IV) treated with VFG between 1994 and 2000 were retrospectively reviewed. Each scan was divided into three regions, the greater trochanter, neck, and head. The intensity at the graft in each region (axially and coronally) was compared to the intensity at the ipsilateral proximal femoral diaph-ysis and assigned a score: less than diaphysis (one), equal to (two), and greater than (three). Cumulative scores were obtained for each subject. Intraobserver variability was 0.93. Surgical failure was defined as conversion to or on the waiting list for total hip arthroplasty.

Thirty percent of hips failed treatment (n=31, mean survival 34.9 months, range 5–98), while 70% were successful (n=73, mean follow-up 56.6 months, range 22–100). Bone scan scores were significantly lower in the failed group (mean 7.1, range 6–12) compared to the successful group (mean 8.5, range 6–18), p=0.03. Positive skewness (+1.7) was demonstrated as 64% of hips had a score of six while 36% had a score > 6 (range 8–18). Logistic regression demonstrated that a bone scan score > 6 was associated with success, p=0.028, with an odds ratio of 3.08 (1.13–8.40).
