Lateral condylar fractures of the humerus in children: fixation with partially threaded 4.0-mm AO cancellous screws.

Thirty-seven children with fresh, displaced (more than 2 mm in any direction) fractures of the lateral condyle of the humerus were treated by open reduction and internal fixation with a partially threaded 4.0-mm diameter AO lag screw. They were reviewed at a mean follow-up of 4.8 years. Painless, full-elbow movements were obtained in 36 cases. Delayed union, with loss of 10 degrees of elbow motion, was observed in one case (2.72%). Radiologically, less than 4 degrees of varus deviation, compared with the contralateral side, was found in four cases (10.8%). Mild fishtailing was observed in three cases (8.18%). Nonunion, avascular necrosis or clinically significant premature epiphysial fusion was not observed. Elbow function was excellent, irrespective of minor radiologic abnormalities.

Intertrochanteric fractures of the femur and osteoarthritis of the ipsilateral hip.

We retrospectively reviewed the radiographs of 255 patients with intertrochanteric fractures over a 2 year period. The incidence of osteoarthritis of the hip joint in these patients was 12.16%, which is less than that reported in the general population, and which confirms the protective effect of osteoarthritis against intertrochanteric fractures. Osteoarthritis was mild in 14, moderate in 19, and severe in 4 hips. Seventeen of the 33 patients had died or were too ill to attend a review clinic. The remaining 16 patients (18 hips) were followed up clinically and radiographically 1 to 5.5 years (mean 2.25 years) after internal fixation of the hip fracture. Three patients with severe osteoarthritis, who were waiting for a total hip replacement before the hip fracture occurred became asymptomatic. There was no significant clinical or radiographic progression of mild and moderate hip osteoarthritis in the remaining 13 patients (15 hips). Intertrochanteric fractures appear to have a beneficial "osteotomy-like" effect on hip osteoarthritis in symptomatic patients.

Percutaneous pinning for radial neck fractures.

Eight patients with angulated radial neck fractures were successfully treated by percutaneous reduction and pinning. The operative technique is simple and is not associated with any important complications. This technique may however not be suitable for radial neck fractures with major translocation.

Post-traumatic syringomyelia: a review of the literature.

The need for increased awareness and a high index of suspicion for post traumatic syringomyelia is emphasised. Early clinical diagnosis confirmed by MRI and early treatment can avert or minimise the potentially devastating effects of post traumatic syringomyelia. The regular and frequent follow up of the patient on a yearly or alternate year basis to monitor the patient with spinal injury for this complication, as well as other complications, is the best way to ensure that post traumatic syringomyelia is diagnosed and managed early in order to avoid further disability.

Assessment of hip abductor function in relation to peritrochanteric heterotopic ossification after closed femoral nailing.

The relationship between peritrochanteric heterotopic ossification and the strength of hip abduction after closed intramedullary nailing for femoral shaft fractures was investigated in 25 patients after a mean follow-up of 2 years (range 9 months to 4 years). The power of hip abduction was assessed and compared with the normal hip. Of the 21 patients with heterotopic ossification, 16 had measurable weakness of hip abduction. Grade III heterotopic ossification resulted in 8-20 per cent weakness of hip abduction, but this was not associated with any disability or symptoms. Clinically important abductor weakness is more likely to be due to ipsilateral fractures or a long nail rather than heterotopic ossification.

Hyponatraemia after acute spinal injury.

Of 134 patients admitted to the Midlands Centre for Spinal Injuries within 2 days of the spinal injury during 1991-1992, 25 developed hyponatraemia in the acute phase. Hyponatraemia was most common among patients with complete tetraplegia (45 per cent) and these patients tended to be younger as well as have more severe and prolonged hyponatraemia. Overhydration is a common cause of hyponatraemia in this group of patients and should be avoided.

An open twin incision technique of carpal tunnel decompression with reduced incidence of scar tenderness.

We retrospectively compared a single curved incision for carpal tunnel decompression (group A, 29 wrists in 26 patients) with a twin incision technique (group B, 34 wrists in 30 patients), leaving an intact bridge of skin at the base of the palm. Patients in group B reported statistically significant subjective improvement in the early post-operative period, with fewer residual symptoms and earlier recovery of function compared to patients in group A. After a mean post-operative period of 23 months, 5/29 wrists were symptomatic in group A compared to 1/34 wrists in group B at 13 months, but this was not statistically significant. The twin incision technique is easy to perform and allows rapid post-operative recovery. The incidence of scar tenderness is reduced as palmar cutaneous branches of the median nerve are avoided. Because the distal portion of the transverse carpal ligament is divided under direct vision, this technique is not associated with any significant neurovascular complications.

Over-distraction of the radio-carpal and mid-carpal joints following external fixation of comminuted distal radial fractures.

Seven patients with Frykman type 7 and 8 distal radial fractures, who had been treated with external fixation, were noted to have significant over-distraction of 5-8 mm in the radio-carpal and mid-carpal joints. One patient, who also had abnormal negative ulnar variance of 2 mm, had a fair result using modified Gartland and Werly (1951) criteria. The remaining six patients had good results, indicating that over-distraction does not significantly alter the final outcome, so long as a normal distal radio-ulnar relationship is maintained.

Comminuted femoral shaft fractures treated by closed intramedullary nailing and functional cast bracing.

Eighty-one patients with comminuted femoral shaft fractures were treated by closed unlocked Küntscher nailing and functional cast bracing for 1 to 4 weeks postoperatively depending on the degree of comminution. The mean follow-up period was 27.6 months. The average time required for fracture healing was 14 weeks. There was one delayed union. One fracture united with more than 10 degrees of rotational malalignment; shortening of more than 1 cm was present in four cases. Two patients had more than 20 degrees of limitation of hip and knee movement.

Results of excision of calcaneal prominence.

Calcaneal prominence in 22 patients (37 heels) with moderate-to-severe symptoms was treated by excision after a minimum of 6 months of conservative treatment. There were 21 good, 12 fair and 4 poor results. Calcaneal exostectomy is a useful procedure in carefully selected patients.

Management of childhood femoral neck fractures.

Forty-three children with displaced transcervical femoral fractures were reviewed at a mean follow-up of 7.2 years and results were assessed using Ratliff's criteria. Of 22 patients treated by internal fixation alone, 10 had good, 6 had fair and 6 had poor results. The results in 21 children treated by internal fixation along with primary transverse intertrochanteric undisplaced osteotomy were: 14 good, 5 fair and 2 poor, but none improved to a statistically significant level (P = 0.139). However, the osteotomy improved the fracture union significantly and no delayed union or non-union was noted in this group (P = 0.05). There were no complications related to the osteotomy itself.

Flexor to extensor tendon transfer for curly toes. 43 children reviewed after 8 (1-25) years.

43 children treated by flexor-to-extensor transfer for a total of 130 curly toes were retrospectively reviewed after a mean period of 8 years. According to an objective scoring system, 37 patients had a satisfactory result and 6 patients had a poor result of one or more toes. We now recommend that children with mild to moderate curly toes should be observed until the age of 6 years, by which time the majority will have had spontaneous correction. The remaining patients should be operated on at that stage because children operated on later had poor results. Attention should be paid to the surgical technique because the long flexor tendons are often bipartite.

Ulnar translocation after excision of giant cell tumour of distal radius.

Translocation of the ipsilateral ulna has been carried out in six cases after radical resection of a giant cell tumour of the distal radius. The carpo-ulnar junction united readily in all cases. Union of the radio-ulnar junction is often delayed, but this can be overcome by the addition of cancellous grafts at the time of ulnar translocation. All the patients had very good forearm rotation and an acceptable appearance. There were no significant complications.

Morphological variations of the ulnar styloid process.

P.A. radiographs of both wrists were taken in 400 normal individuals to study the configuration of the styloid process of the ulna. Five different morphological variations were noticed, the commonest being an elongated process (102 wrists). Medially deviated (41 wrists), parrot beaked (27 wrists) and hypertrophic (16 wrists) patterns were less common. One person had bilateral unfused separate ossification centres for the ulnar styloid. There was no correlation between the length of the styloid process and ulnar variance.
