In a prospective study, we randomly allocated 39 patients with isolated fractures of the lower two-thirds of the ulnar shaft to treatment either by a prefabricated functional brace or a long-arm cast. Significantly better wrist function and a higher percentage of satisfied patients were found in the braced group. Thirteen patients returned to employment while still wearing the brace but only one was able to work in a cast

We describe a semi-closed method of Herbert screw fixation for acute fractures of the scaphoid. All 40 patients treated achieved solid union with satisfactory wrist function. This technique gave a significantly shorter time to union and allowed an earlier return to manual labour compared with conservative treatment. There were no complications. Semi-closed insertion requires considerable skill, but produces consistently satisfactory results after minimal exposure of the scaphoid

Aims

Improvements in the evaluation of outcomes following peripheral nerve injury are needed. Recent studies have identified muscle fatigue as an inevitable consequence of muscle reinnervation. This study aimed to quantify and characterize muscle fatigue within a standardized surgical model of muscle reinnervation.

Thirty patients who had sustained a Colles' fracture at least four years previously were examined functionally and radiographically. Seventeen had a good radiological result and 13 were considered to have malunion. Functionally the displaced group performed significantly worse than the undisplaced group. We conclude that malunion of a Colles' fracture results in a weak, deformed, stiff and probably painful wrist

Aims

The aim of this study was to examine trends in the management of fractures of the distal radius in Ireland over a ten-year period, and to determine if there were any changes in response to the English Distal Radius Acute Fracture Fixation Trial (DRAFFT).

1. The late results in nineteen cases of total excision of the carpal scaphoid bone for ununited fracture have been reviewed. 2. The results are least satisfactory when there is clinical evidence of arthritis on the dorsal aspect of the wrist, or subluxation of the os magnum and semilunar. In other cases good results usually can be expected. 3. The operation must be done carefully without injury to the neighbouring bones and ligaments. Total excision is preferable to excision of the proximal pole alone

This paper describes a prosthesis for patients who have had a partial amputation of the hand, or who have congenital absence of all or part of the hand. The prosthesis incorporates a new concept whereby the grip is operated by flexion and extension of the wrist. A covering for the prosthesis has been developed using a silicone polymer which produces a lifelike flexible glove. Thirteen patients have so far been fitted with this type of prosthesis, which can give good function and cosmesis

Between 1971 and 1976 eight patients underwent excision of the carpal lunate for pain from Kienbock's disease. The bone was replaced by a silicone rubber implant. An average of 84 months had elapsed when they were reviewed in December 1980. All eight were very satisfied with their operations. Objectively, the clinical results were good, but radiographs showed the presence of degenerative change in the region of the wrist and alteration of the position of the prosthesis on ulnar deviation of the hand. No implant has had to be removed

1. A case of compression of the deep palmar branch of the ulnar nerve by an accessory abductor minimi digiti muscle is described. 2. The morphology of abnormal muscles in the hypothenar region is discussed. 3. Five previously reported cases of ulnar nerve compression at the wrist by an anomalous muscle are reviewed. 4. When symptoms are produced by an anomalous hypothenar muscle, they seem to be related to the anatomical site of the muscle and the presence of muscle hypertrophy. Occupational factors may be important in producing this hypertrophy

1. Excision of the proximal row of the carpus is a useful procedure, with a limited application in patients with ununited fractures of the scaphoid, Kienböck's disease, dislocation of the lunate bone, unreduced mid-carpal dislocations and similar injuries which do not respond to conservative management. 2. It is an acceptable alternative to arthrodesis, even when the wrist is likely to be subjected to heavy use. 3. In the event of failure arthrodesis can still be carried out. 4. Advanced degenerative changes are a contra-indication but mild to moderate changes do not appear to affect the results

Aims

There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data.

Aims

To compare complication-related reoperation rates following primary arthroplasty for proximal humerus fractures (PHFs) versus secondary arthroplasty for failed open reduction and internal fixation (ORIF).

We reviewed 10 patients with symptomatic malunion of a carpal scaphoid fracture. All had displacement with dorsiflexed intercalated segment instability, and suffered from pain, restricted range of movement at the wrist and decreased grip strength. The restriction of flexion-extension and the decreased grip strength correlated with the severity of the DISI deformity. Seven patients had a corrective osteotomy, using an anterior wedge-shape bone graft with internal fixation by Herbert screw, and all had satisfactory results. We believe that symptoms associated with scaphoid malunion are related to consequent carpal deformity

A fracture of the neck of the radius when the head is not ossified can be difficult to assess and treat. In a four-year-old child we suspected from the radiographs that there was an O’Brien type-III injury after trauma. Partial manual reduction of the non-ossified radial head was completed using the Métaizeau technique of intramedullary Kirschner (K-) wiring aided by intraoperative arthrography. The child had a full range of movement at the elbow and wrist when reviewed 11 weeks after the injury, three weeks after removal of the K-wire. We suggest that intraoperative arthrography is a useful complement to the Métaizeau technique for successful reduction of fractures of the radial neck in the presence of a non-ossified radial head

1. Sixty-one cases of compression of the ulnar nerve are reported, forty at the elbow and twenty-one at the wrist. Although contributory factors may include deformity, osteoarthritis, injury, ganglia and other tumours, the narrow anatomical confines of the nerve at these two levels are noteworthy and alone may produce nerve compression. 2. Careful clinical examination will usually determine the level of involvement if not the exact pathology. Surgical exploration is indicated both as a diagnostic and therapeutic procedure in most cases. 3. Following removal of the compressing agent rapid recovery occurred in most cases

Aims

To describe and analyze the mid-term functional outcomes of a large series of patients who underwent the Hoffer procedure for brachial plexus birth palsy (BPBP).

Studies derived from analyses of radiographs and dissections of cadaveric wrists have been directed at testing and disproving the commonly held theories that link chip fractures of the os triquetrum with avulsion. The authors found that the mechanism of such injuries involved a chisel action of the ulnar styloid upon the dorsum of the os triquetrum; furthermore, the impact of a fall on the outstretched arm with the hand rigidly held in strong dorsiflexion and ulnar deviation could be forceful enough to fracture the body of the os triquetrum as well. In all cases a striking prolongation of the ulnar styloid, beyond the surface of the ulnar head, was consistently noted

Dysfunction of the distal radio-ulnar joint caused by traumatic, congenital and inflammatory onditions is usually treated by excision of the head of the ulna. This operation can induce ulnar carpal shift, with complications such as instability with poor grip, pain and clumsiness of the wrist, if the lower articular surface of the radius is normally inclined, or overinclined towards the ulna. These complications can be avoided by use of an operation producing pseudarthrosis of the distal part of the ulna, with fusion of the radio-ulnar joint (Lauenstein) if there is dislocation, radio-ulnar discrepancy or arthritis, or without fusion (Baldwin) if the joint, in spite of keeping normal articular surfaces, has its movement blocked by malunion of a radial fracture

1. A study has been made of thirty-two patients who had had operations for their spastic hands. 2. In twenty-seven a flexor muscle slide was done, either by itself or in association with an arthrodesis of the wrist. The rationale of the operation is discussed. 3. The first muscle slide was done in 1959 and the average follow-up was seven and a half years. 4. Selection is crucial : drive, usually coupled with intelligence, is essential for success. 5. Operation is not a replacement for physical therapy. The object is to make rehabilitation easier. The flexor muscle slide, in carefully chosen cases, may play a significant part in achieving this

1. In patients who develop de Quervain's disease variations from the standard pattern of tendons at the wrist are the rule rather than the exception. 2. Conservative treatment is of no value. 3. Adequate exposure, allowing full recognition of all anatomical structures in the region, is advisable, but branches of the radial nerve must be treated with respect. 4. The extensor pollicis brevis tendon is normally small and may pass through a separate osteofibrous canal. 5. Though incision only of the stenosing tendon sheaths may be sufficient, thorough excision is more certain and does no harm
