This is a retrospective study of six children with ununited scaphoid fractures treated conservatively. Their mean age was 12.8 years (9.7 to 16.3). Five had no early treatment. Radiological signs of nonunion were found at a mean of 4.6 months (3 to 7) after injury. Treatment consisted of cast immobilisation until clinical and radiological union. The mean clinical and radiological follow-up was for 67 months (17 to 90). We assessed the symptoms, the range of movement of the wrist and the grip strength to calculate the Modified Mayo Wrist score.

The fracture united in all patients after a mean period of immobilisation of 5.3 months (3 to 7). Five patients were pain free; one had mild pain. All returned to regular activities, and had a range of movement and grip strength within 25% of normal, resulting in an excellent Modified Mayo Wrist score.

Prolonged treatment with cast immobilisation resulted in union of the fracture and an excellent Modified Wrist Score in all patients.

Introduction. Scaphoid nonunions remain controversial with regard to optimal management. The objective of this article is to compare our clinical experience in the treatment of patients with scaphoid nonunion using distal radius non vascularised bone graft with that of iliac crest bone graft. Material & Methods. We conducted a prospective randomized study comparing the clinical, functional and radiographic results of 42 patients treated for scaphoid nonunion using a non-vascularised bone graft from the dorsal and distal aspect of the radius (group I), relative to 46 patients treated by means of a conventional non-vascularised bone graft from the iliac crest (group II). All nonunions were stabilized with single Herbert screw. Results. Bone fusion was achieved in 87.1% of group I and 86.5% of group II patients. Functional results were good to excellent in 76.0% of the patients in group I and 72.5% in group II. The average grip power, as well as wrist flexion and extension were similar in both groups. However, the donor site morbidity was much higher in group II (4 cases of hematoma, 6 cases of chronic pain and 1 anterior superior iliac spine avulsion) fracture. No complication was seen in group I. Conclusion. We conclude that nonvascularized distal radius bone grafting yields similar union rate as well as functional outcome as compared to iliac crest bone graft with no donor site morbidity

Aims

Occult (clinical) injuries represent 15% of all scaphoid fractures, posing significant challenges to the clinician. MRI has been suggested as the gold standard for diagnosis, but remains expensive, time-consuming, and is in high demand. Conventional management with immobilization and serial radiography typically results in multiple follow-up attendances to clinic, radiation exposure, and delays return to work. Suboptimal management can result in significant disability and, frequently, litigation.

Aims

There is a lack of published evidence relating to the rate of nonunion seen in occult scaphoid fractures, diagnosed only after MRI. This study reports the rate of delayed union and nonunion in a cohort of patients with MRI-detected acute scaphoid fractures.

The use of pulsed electromagnetic fields (PEMF) to stimulate bone growth has been recommended as an alternative to the surgical treatment of ununited scaphoid fractures, but has never been examined in acute fractures. We hypothesised that the use of PEMF in acute scaphoid fractures would accelerate the time to union by 30% in a randomised, double-blind, placebo-controlled, multicentre trial. A total of 53 patients in three different medical centres with a unilateral undisplaced acute scaphoid fracture were randomly assigned to receive either treatment with PEMF (n = 24) or a placebo (n = 29). The clinical and radiological outcomes were assessed at four, six, nine, 12, 24 and 52 weeks.

A log-rank analysis showed that neither time to clinical and radiological union nor the functional outcome differed significantly between the groups. The clinical assessment of union indicated that at six weeks tenderness in the anatomic snuffbox (p = 0.03) as well as tenderness on longitudinal compression of the scaphoid (p = 0.008) differed significantly in favour of the placebo group.

We conclude that stimulation of bone growth by PEMF has no additional value in the conservative treatment of acute scaphoid fractures.

We reviewed 59 bone graft substitutes marketed by 17 companies currently available for implantation in the United Kingdom, with the aim of assessing the peer-reviewed literature to facilitate informed decision-making regarding their use in clinical practice. After critical analysis of the literature, only 22 products (37%) had any clinical data. Norian SRS (Synthes), Vitoss (Orthovita), Cortoss (Orthovita) and Alpha-BSM (Etex) had Level I evidence. We question the need for so many different products, especially with limited published clinical evidence for their efficacy, and conclude that there is a considerable need for further prospective randomised trials to facilitate informed decision-making with regard to the use of current and future bone graft substitutes in clinical practice.

We undertook a simultaneous prospective two-centre study to examine why patients with fractures of the proximal femur experience a delay in undergoing surgery.

At centre 1, 23 of 105 patients (22%) suffered an avoidable delay, 18 (78%) because of a lack of theatre capacity while at centre 2, 71 of 130 patients (55%) had an avoidable delay, with 54 (76%) because of this cause. Miscellaneous reasons such as poor ward management, co-existing medical conditions, and lack of equipment were responsible for the remainder of the delays.

Without a substantial increase in operating capacity for acute trauma, it will not be possible to comply with guidelines which recommend surgical treatment within 24 hours in elderly and vulnerable patients.
