Fractures and plastic deformities of the forearm are common in children. While axial deformities are easily recognised and treated, bowing of the radius may be overlooked. Physiological bowing is essential for full rotation of the forearm. We have used the method of Schemitsch and Richards to estimate the degree of bowing in 100 children who had not suffered a fracture of the forearm. The site of maximum bowing remained constant at 60.39% of the length of the radius (95% CI 59.65 to 61.14). The value of maximum bowing did not exceed 10% of the total length (mean value 7.21%; 95% CI 7.00 to 7.41). This study provides information that can be useful for the diagnosis of bowing and for the evaluation of post-traumatic deformities

Aims. We describe the use of a protocol of irrigation and debridement (I& D) with retention of the implant for the treatment of periprosthetic infection of a total elbow arthroplasty (TEA). This may be an attractive alternative to staged re-implantation. . Patients and Methods. Between 1990 and 2010, 23 consecutive patients were treated in this way. Three were lost to follow-up leaving 20 patients (21 TEAs) in the study. There were six men and 14 women. Their mean age was 58 years (23 to 76). The protocol involved: component unlinking, irrigation and debridement (I& D), and the introduction of antibiotic laden cement beads; organism-specific intravenous antibiotics; repeat I& D and re-linkage of the implant if appropriate; long-term oral antibiotic therapy. . Results. The mean follow-up was 7.1 years (2 to 16). The infecting micro-organisms were Staphylococcus aureus in nine, coagulase-negative Staphylococcus in 13, Corynebacterium in three and other in six cases. Re-operations included three repeat staged I& Ds, two repeat superficial I& Ds and one fasciocutaneous forearm flap. One patient required removal of the implant due to persistent infection. All except three patients rated their pain as absent or mild. Outcome was rated as good or excellent in 15 patients (mean Mayo Elbow Performance Score 78 points, (5 to 100) with a mean flexion-extension arc of 103° (40° to 150°)). . Conclusion. A staged protocol can be successful in retaining stable components of an infected TEA. Function of the elbow may compare unfavourably to that after an uncomplicated TEA.

The aims of this study were to assess the efficacy of a newly designed radiological technique (the radial groove view) for the detection of protrusion of screws in the groove for the extensor pollicis longus tendon (EPL) during plating of distal radial fractures. We also aimed to determine the optimum position of the forearm to obtain this view. We initially analysed the anatomy of the EPL groove by performing three-dimensional CT on 51 normal forearms. The mean horizontal angle of the groove was 17.8° (14° to 23°). We found that the ideal position of the fluoroscopic beam to obtain this view was 20° in the horizontal plane and 5° in the sagittal plane. We then intra-operatively assessed the use of the radial groove view for detecting protrusion of screws in the EPL groove in 93 fractures that were treated by volar plating. A total of 13 protruding screws were detected. They were changed to shorter screws and these patients underwent CT scans of the wrist immediately post-operatively. There remained one screw that was protruding. These findings suggest that the use of the radial groove view intra-operatively is a good method of assessing the possible protrusion of screws into the groove of EPL when plating a fracture of the distal radius.

Aims

Arthroplasties of the elbow, including total elbow arthroplasty, radial head arthroplasty, distal humeral hemiarthroplasty, and radiocapitellar arthroplasty, are rarely undertaken. This scoping review aims to outline the current research in this area to inform the development of future research.

Transfer of flexor carpi ulnaris combined with selective release of the flexor pronator origin was undertaken in 35 patients with hemiplegic cerebral palsy for a pronation flexion deformity of the forearm, hand and wrist. The patients were divided into four groups depending on the severity of the deformity, the surgical procedure recommended, potential hand function and prognosis. The procedure reduces the power of wrist and finger flexion by release of the flexor pronator origin, and reinforces the strength of extension and supination of the wrist by transfer of flexor carpi ulnaris. After a mean follow-up of four years the appearance of the hand and forearm improved in all patients. None lost movement and all gained improved mobility of the forearm, wrist and hand. There was no overcorrection

Deformity of the forearm is common in patients with hereditary multiple exostoses, producing cosmetic and functional impairment in which shortening of the ulna is a significant factor. The results of ulnar lengthening in 10 forearms of eight patients are reported. Lengthening was performed by osteotomy of the shaft followed immediately by a bone graft and internal fixation, or by gradual distraction with an external fixator. In all patients the appearance was improved and the range of radial deviation at the wrist was increased. In most patients forearm movement and radial head stability were improved. Partial recurrence of the deformity was seen during the follow-up of skeletally immature patients, but in general ulnar lengthening was found to be a useful operation

Symptoms due to a supracondylar spur of the humerus, although rare, are common enough to make it the subject of routine examination of a patient with pain and disturbance of sensibility of the hand. It can mimic the carpal tunnel syndrome; it may produce ulnar nerve symptoms. Irritation or compression of either the brachial artery or, if there is a high division of it, the ulnar artery, may cause episodes of ischaemic pain in the forearm. The clinical features of a supracondylar spur causing symptoms are: symptoms of median nerve compression; forearm claudication; a palpable spur about two inches above the medial epicondyle; and disappearance of the radial or ulnar pulse on full extension and supination of the forearm

We present the results of a retrospective series of 41 Sauve-Kapandji procedures carried out for complications of fractures of the distal radius. All the operations were undertaken by one surgeon with a mean follow-up of 32 months. A total of 37 patients was available for clinical review. The indications for surgery were pain on the ulnar side of the wrist and decreased rotation of the forearm. Intraperiosteal and extraperiosteal techniques were used for resection of the ulna, with no difference in outcome. Patients were assessed for pain, rotation of the forearm and complications. A Mayo Modified Wrist Score was used. Pain was improved in 25 of the 37 patients, and unchanged in ten. Rotation of the forearm returned to within 7° of the uninjured side. The results are discussed in relation to the presence of preoperative malunion of the distal radius, age and the functional outcome. Age is not a contraindication for this procedure

In severe forearm injuries, the diagnosis of disruption of the interosseous membrane is frequently delayed and sometimes missed, giving difficulties in the salvage of forearm stability. We studied the structure and function of the interosseous membrane in 11 cadaver preparations, using mechanical and histological analysis. Seven of the specimens tested in uniaxial tension sustained a mid-substance tear of the central band of the membrane at a mean peak load of 1038 ± 308 N. The axial stiffness was 190 ± 44 N/mm with elongation to failure of 10.34 ± 2.46 mm. These results provide criteria for the evaluation of reconstructive methods. A preliminary clinical investigation of the use of ultrasound suggests that this may be of value in the screening of patients with complex fractures of the forearm, and for investigating the natural history of tears of the interosseous membrane

The August 2013 Trauma Roundup. 360 . looks at: reverse oblique fractures do better with a cephalomedullary device; locking screws confer no advantage in tibial plateau fractures; it’s all about the radius of curvature; radius of curvature revisited; radial head replacement in complex elbow reconstruction; stem cells in early fracture haematoma; heterotrophic ossification in forearms; and Boston in perspective

The clinical features, management and outcome of bleeding into the muscles of the upper limb of 44 patients are reported. Of 158 episodes of bleeding, 99% were treated within two hours of onset of symptoms and the mean time to complete restoration of function was 2.1 days. The most frequent site of bleeding was the deltoid muscle (24%), followed by the forearm flexors (23.5%), brachioradialis (19.5%), biceps (14%), forearm extensors (11%) and triceps (8%). The majority of bleeds presented with pain, either on movement or at rest, or with tenderness. Bleeds into the biceps required the most transfusions (mean 2.00) and took the longest to resolve (mean 4 days). Bleeding into the flexors and extensors of the forearm resolved most rapidly. The policy of early treatment has been shown to be effective in prompting early and complete recovery

Aims

Low-energy distal radius fractures (DRFs) are the most common upper arm fractures correlated with bone fragility. Vitamin D deficiency is an important risk factor associated with DRFs. However, the relationship between DRF severity and vitamin D deficiency is not elucidated. Therefore, this study aimed to identify the correlation between DRF severity and serum 25-hydroxyvitamin-D level, which is an indicator of vitamin D deficiency.

Aims

This study aims to report the outcomes in the treatment of unstable proximal third scaphoid nonunions with arthroscopic curettage, non-vascularized bone grafting, and percutaneous fixation.

The June 2012 Wrist & Hand Roundup. 360. looks at; radial osteotomy and advanced Kienböck's disease; fixing the Bennett fracture; PEEK plates and four-corner arthrodesis,;carpal tunnel release and haemodialysis; degloved digits and the reverse radial forearm flap; occupational hand injuries; trapeziometacarpal osteoarthritis; fixing the fractured metacarpal neck and pyrocarbon implants for the destroyed PIPJ

We identified 11 women with a mean age of 74 years (65 to 81) who sustained comminuted distal radial and ulnar fractures and were treated by volar plating and slight shortening of the radius combined with a primary Sauvé-Kapandji procedure. At a mean of 46 months (16 to 58), union of distal radial fractures and arthrodesis of the distal radioulnar joint was seen in all patients. The mean shortening of the radius was 12 mm (5 to 18) compared to the contralateral side. Flexion and extension of the wrist was a mean of 54° and 50°, respectively, and the mean pronation and supination of the forearm was 82° and 86°, respectively. The final mean disabilities of the arm, shoulder and hand score was 26 points. According to the Green and O’Brien rating system, eight patients had an excellent, two a good and one a fair result. The good clinical and radiological results, and the minor complications without the need for further operations related to late ulnar-sided wrist pain, justify this procedure in the elderly patient

Posterolateral rotatory instability is the most common type of symptomatic chronic instability of the elbow. In this condition the forearm complex rotates externally in relation to the humerus, causing posterior subluxation or dislocation of the radial head. The lateral ligament complex, radial head and coronoid process are important constraints to posterolateral rotatory instability, and their disruption is involved in the pathogenesis of this condition. The diagnosis relies on a high index of clinical suspicion, active and passive apprehension tests, and examination under anaesthesia. Surgical treatment has given consistently successful results. Open reconstruction of the lateral ligaments with a tendon graft has been the procedure of choice, with arthroscopic techniques emerging as a potential alternative

We present two rare variations related to compartment syndrome. The first is a 69-year-old hypertensive man with compartment syndrome of the arm. The second is a 58-year-old man with compartment syndrome of the forearm with severe compensatory hypertension

Aims

Alcoholism is a well-known detrimental factor in fracture healing. However, the underlying mechanism of alcohol-inhibited fracture healing remains poorly understood.

Aims

The aim of this study was to determine whether there is a correlation between the grade of humeral osteoarthritis (OA) and the severity of glenoid morphology according to Walch. We hypothesized that there would be a correlation.
