The anatomical site of constriction of the median nerve in patients with severe idiopathic carpal tunnel syndrome.

During open carpal tunnel release in patients with severe idiopathic carpal tunnel syndrome, an area of constriction in the substance of the median nerve is frequently noted. In a prospective study of 30 patients, the central point of the constricted part of the nerve was determined intraoperatively and found to be, on average, 2.5 (range 2.2-2.8)cm from the distal wrist crease. This point always corresponded to the location of the hook of the hamate bone. These intraoperative findings were compared with the "narrowest" point of the carpal canal as determined by anatomical and radiological studies in the literature.

Phalangeal neck fractures in adults.

The author investigated the pattern of injury and outcome of management in 11 adults with phalangeal neck fractures. The mean age was 40 years. The fracture occurred at the neck of the proximal phalanx of the thumb in seven cases and at the neck of the middle phalanx of the fingers in the remaining four cases. One patient had an undisplaced (Type I) fracture and was treated with splinting; the final result was graded as excellent. Nine patients had Type II fractures (the displaced distal fragment maintaining bone-to-bone contact with the proximal fragment) and all patients were treated with closed reduction and single K-wire fixation. The final outcome of Type II fractures was considered good in eight patients and fair in one patient. One patient had a Type III fracture (the displaced distal fragment was rotated 180 degrees with no bone-to-bone contact with the proximal fragment). The fracture required open reduction and K-wire fixation and the final result was poor.

Metacarpal shaft fractures of the fingers: treatment with interosseous loop wire fixation and immediate postoperative finger mobilisation in a wrist splint.

It is widely believed that interosseous loop wire fixation of metacarpal shaft fractures alone is not rigid enough to allow immediate postoperative mobilisation. In this report, the author reviews the results in 36 cases of metacarpal shaft fractures of the fingers treated by interosseous loop wire fixation and immediate postoperative mobilisation of all finger joints. The study included 30 males and six females, with a mean age of 31 (range 12-52) years. The fracture pattern was transverse in 26 and oblique, or spiral, in the remaining 10 patients. Following loop wire fixation, the wrist was immobilised using a volar plaster splint for 3 weeks but all finger joints were mobilised immediately after surgery. After a mean follow-up of 8 weeks, all patients, except two, had regained full range of motion of the fingers and no complications were noted. It was concluded that interosseous loop wire fixation of metacarpal shaft fractures is rigid enough to allow immediate postoperative finger mobilisation in a wrist splint and achieve good functional results.

Use of the medial upper arm fascia to bridge biceps tendon defects.

Options to bridge biceps tendon defects which have been described in the literature include fascia lata, semitendinosus tendon, flexor carpi radialis, Achilles tendon-calcaneus composite allografts and Achilles tendon allografts. In this study, the author reports the use of the upper arm fascia. This option is considered most suitable for patients who require simultaneous pedicled latissimus dorsi flap coverage of concurrent traumatic complex anterior elbow defects.

Air gun pellet injuries of the hand.

The purpose of this paper is to report our experience in a group of patients who suffered injuries by air gun pellets to the hand. There were 22 males and 2 females, with a mean age of 12 years. The pellet was embedded in the hand in 18 patients and it went through and through in the remaining six. There were no vascular injuries. Associated injuries to tendon, nerve or bone occurred in six patients. There was little soft-tissue devitalization and none of the fractures required fixation or splinting. Immediate postoperative mobilization resulted in full range of motion in all patients. In conclusion, pellets produce a different injury pattern, with a more benign course, than other types of bullet injury.

An alternative approach for correction of constricted ears of moderate severity.

Moderately severe constricted ears are characterised by lidding, moderate reduction of the vertical height of the upper ear (reduced scapha, absent superior crus) and prominence with absent antihelix. Techniques described for the correction of moderate constricted ear deformities included an attempt to expand the upper part of the ear by various cartilage transection and/or flap techniques. In the current paper, an alternative approach is presented and is based on the recreation of an antihelix (with Mustarde sutures) and excision of the lidding without performing cartilage expansion procedures. The technique was used in four patients with satisfactory results despite the persistence of the deficient scapha and triangular fossa. No recurrence of the cupping deformity was observed (follow up ranged from 6 months to 4 years with a mean of 2 years) and this was attributed to the use of a 'mastoid hitch' as an adjunctive technique to prevent recurrence.

Fabrication of silicone oral splints for severe burn microstomia in children.

This paper describes a simple technique of fabrication of oral splints (from silicone blocks), which can be utilized in the postoperative period following the release and graft of anterior oral contractures in children. Advantages of the silicone splint when compared to standard acrylic splints are discussed.

Vicryl Rapide versus Vicryl suture in skin closure of the hand in children: a randomized prospective study.

This randomized prospective clinical study compared the use of two absorbable sutures, Vicryl Rapide versus Vicryl, in elective paediatric hand surgery. Sixty children were randomly allocated into two groups (30 in each group) and all were seen and assessed at 3 and 6 weeks for wound complications and suture reactions. Five problems occurred in the Vicryl treatment group and none in the Vicryl Rapide group (P=0.03). All the problems were related to the delayed absorption of the Vicryl suture material and hence the prolonged presence of the suture in the hands of these children. It is concluded that Vicryl Rapide sutures are more suitable than Vicryl ones in paediatric hand surgery.

Elbow flexion reconstruction by Steindler flexorplasty in obstetric brachial plexus palsy.

The results of Steindler flexorplasty in nine patients with obstetric brachial plexus palsy are reported. There were 5 girls and 4 boys with a mean age of 6 (range 2-13) years. Selection criteria for the procedure included strong (at least M4) grip strength and wrist and elbow extension, as well as the presence of the "Steindler effect". Pre-operatively, elbow flexion was rated as M0 or M1 in three patients and M2 in the remaining six patients. Intra-operatively, the detached common flexor origin was advanced 5 to 7 cm and fixation was done to the anterior humerus either with direct suture to the periosteum (in younger children) or suturing into a drill hole in the humerus (in older children). Postoperatively, the elbow was immobilized in flexion and supination for 6 weeks. At a mean follow-up of 5 years, the results in eight patients were good with mean active elbow flexion against resistance of 110 degrees and a mean elbow flexion contracture of 35 degrees. The result in the remaining patient was poor (unsuccessful transfer). It is concluded that the results of the Steindler flexorplasty in obstetric brachial plexus palsy patients are good and reliable, provided patient selection is careful.

Thumb polydactyly with symphalangism.

Three cases of thumb polydactyly in which one of the components demonstrated symphalangism are reported. This is a very rare anomaly and only one similar case could be found in the literature. The rarity of this anomaly was explained by the occurrence of two different abnormal molecular events along two different limb growth axes. Finally, the anomaly does not fit into the classification systems described for thumb polydactyly.
