Purpose

The aim of this study is to assess the safety and efficacy of a remote-operated magnetic growth rod in the treatment of 11 patients with progressive early onset scoliosis (EOS).

Purpose of the study

We propose a simple classification for adolescent idiopathic scoliosis (AIS) based on two components which include the curve type and shoulder level and suggest a treatment algorithm for AIS.

Objective: This study was performed to review the current treatment and outcome of extra abdominal fibromatosis in our hospital, supplemented by a current review of the literature.

Method: A retrospective study of 72 patients with fibromatosis seen at the Royal National Orthopaedic Hospital (RNOH) between 1980 and 2009 was performed. Patients were identified using the databases at the peripheral nerves injury (PNI) unit and the histopathology department. Medical and radiological records were reviewed.

Results: There were 72 patients treated at the Sarcoma and PNI units. 40 patients were primary referrals, and 32 more had operations at the referring hospital. An operation was not carried out in 5 patients. 48 patients were treated by operation alone and this was supplemented by adjuvant therapy in 19 patients. Recurrence was seen in 24 (50.0%) of the operation alone group and 10 (52.6%) in the operation and adjuvant therapy group. The rate of recurrence was lower with complete excision. However, complete excision was impossible in some cases because of extension into the chest or spinal canal, or involvement with the axial vessels and lumbosacral or brachial plexus.

Conclusion: We suggest that operative excision should seek to preserve function and that supplementary adjuvant therapy may reduce the risk of recurrence, although excision margin appears to be the most important factor. The aggressive, infiltrative behaviour of deep fibromatoses and the associated genetic mutations identified, clearly distinguish them from the superficial fibromatoses and makes their treatment more difficult and dangerous, especially where vital structures are involved. We agree with the recent recommendation that these lesions should be treated in regional soft tissue sarcoma units.

Background: Arthroscopic visualisation of the postero-medial and posterolateral compartments of the knee through the intercondylar notch using the anterolateral and anteromedial portals respectively is not commonly practiced. The purpose of this study was to prospectively evaluate whether these views are useful either diagnostically, therapeutically or both in a routine knee arthroscopy.

Patients and Methods: It is a prospective study of two hundred consecutive patients who underwent a routine knee arthroscopy in our unit using the standard portals following an appropriate clinical and radiological evaluation. Posteromedial and posterolateral compartment visualisation through the intercondylar notch was undertaken in all the patients. An evaluation of the ease of the technique, the usefulness of visualisation and the morbidity associated with the procedure were recorded.

Results: The technique was deemed simple to perform in 91% of the patients. It was found to be more difficult in knees with degenerative joint disease. Posteromedial and posterolateral compartment visualisation was found to be useful for diagnosis or treatment in 15% and 6% of the diagnosed conditions respectively. The technique was most useful for tears of the posterior horn of the medial meniscus, most of which were not detected by visualisation from the anteromedial compartment alone. Visualisation of the compartments was deemed adequate in 98% of the patients. There was no morbidity associated with this procedure.

Conclusion: We believe that visualisation of the pos-teromedial and posterolateral compartment in a routine knee arthroscopy is beneficial; and an easy and safe procedure to perform.

This study investigates the efficacy of the AO Pi-plate in the treatment of complex, unstable, intra-articular fractures of the distal radius.

A retrospective study of 17 patients was carried out who underwent open reduction and internal fixation for dorsally displaced, intra-articular fractures of the distal radius using the AO Pi-plate. All patients were assessed clinically and radiologically post-operatively. The final functional outcome was assessed using the Gartland & Werley scoring system.

The average follow-up period was 34.3 months. 94% (16 patients) of the fractures were classified as AO type C fractures. The wrist movement was restored to a near normal range in all cases. The mean grip strength was 67% of the uninjured hand. The functional outcome as measured by the Gartland & Werley scoring system showed excellent and good results in 88% of the patients. Radiographic assessment revealed an average articular step-off of 0mm post-operatively. The implant removal rate was 29% (5 patients) and the main reason for that was extensor tenosynovitis.

Conclusion: Our study demonstrates that although the functional outcome after using the Pi-plate for complex distal radius fractures is good, there is a significant incidence of extensor tenosynovitis. We recommend that the implant is best used for Type C fractures and be removed electively after fracture union.

Introduction and Aims: The purpose of our study was to assess the efficacy of double osteotomy of the radius and ulna for correction of Madelung’s deformity. Made-lung’s deformity is a congenital alteration of the growth of the ulnar portion of the distal radius resulting in pain, decreased function of the wrist and hand and serious aesthetic disturbances.

Method: Four wrists in four patients with a mean age of 18.3 years were treated for symptomatic increased ulnar and volar inclination of the distal articular surface of the radius. All patients complained of wrist pain. In addition, two of them were dissatisfied with the aesthetic appearance of their wrist and the restricted range of movement. A double osteotomy of the radius and ulna was performed. The ulna was stabilised with a six-hole semi-tubular plate and the radius with a titanium T-plate.

Results: At one-year follow-up: pain relief and cosmetic appearance were satisfactory in all patients. Grip strength improved by 5.3 pounds. Average flexion improved from 63 to 67 degrees and pronation from 59 to 66 degrees. Abduction increased from three to six degrees and adduction from 16 to 21 degrees. Realignment of the wrist was shown radiographically by a change of ulnar inclination and volar inclination of the radius from 35.5 to 24 degrees and 15.5 to 10.5 degrees respectively. There was no evidence of recurrence of the deformity in any of the four wrists.

Conclusion: The initial results with the double osteotomy of the radius and ulna for Madelung’s deformity are promising but need longer follow-up.
