This presentation discusses the experience at our Centre with treating traumatic thoracolumbar fractures using percutaneous pedicle screw fixation and also looks at clinical and radiological outcomes as well as complications.

Reverse polarity shoulder replacements are indicated in cases of gleno-humeral arthritis with the presence of rotator cuff muscle dysfunction. Despite some studies demonstrating early improvement in function and pain, limited information still exists regarding the durability and longer term outcomes of these prostheses. The reported complication rates have been reported to range from 0–68%.

Post-operative clinical complication rates of three commonly used reverse polarity total shoulder replacements (Delta, Verso and Equinoxe) were evaluated against those mentioned in the literature to predict satisfactory outcome.

A retrospective review of 54 patients (3.5F:1M) and 64 operations (27L:37R) between 2004–2011 was carried out. Post-operative complications were searched for through medical records, the local hospital database (BLuespearIT) and the Picture Archiving and Imaging System (PACS). All operations were performed by two experienced consultant-grade orthopaedic shoulder surgeons.

The mean age at time of operation was 75.9 years (range 64–94). 33 Delta, 19 Equinoxe and 12 Verso prostheses were inserted. Three patients were excluded from the study due to insufficient information from medical records and radiography. Total complications were seen in 25 % of operated cases:- dislocation (6), fracture (4), deep infection (2), significant post-operative pain (1) and deltoid muscle dysfunction (3). Complications categorised according to prosthesis type were:- Delta (24%), Equinoxe (32%) and Verso (8%).

Short to medium term complication rates using reverse polarity total shoulder replacements are higher than the majority of the current literature suggests. The Verso is associated with the least number of complications which may correlate with its minimally invasive approach.

Distension arthrography of the glenohumeral joint was adopted as a mainstream treatment for adhesive capsulitis before any randomised controlled trials were performed. Interpretation of the effectiveness of this procedure rests on data from cohort studies of which there are few of high quality. Papers reporting on the long-term results have either excluded diabetic patients or failed to report on patient orientated outcomes.

We present a prospective cohort study of 51 patients with adhesive capsulitis of the shoulder who had a distension arthrogram performed by a single radiologist as a primary intervention. We included diabetic patients.

Range of movement (ROM), Oxford shoulder score (OSS) and a visual analogue pain score (VAS) were recorded pre-procedure, at 2 days and 1 month. OSS and VAS were recorded again at a mean of 14 months post procedure (range 8–26 months).

OSS improved from pre-procedure mean of 22.3 by 16.9 points at final follow up in September 2011 (p < 0.001) whilst VAS improved from a mean pre-procedure of 7.1 by −3.5 by September 2011 (p< 0.001). ROM improved with a mean increase of 39.3 degrees in flexion, 55.2 degrees in abduction and 19.5 degrees in external rotation by 1 month (p < 0.001 for all). The outcome in diabetic patients was the same as in non-diabetic patients.

We conclude that distension arthrography is a safe and effective treatment for adhesive capsulitis.

Aims: Evaluate the outcome of orthopaedic intervention in children who sustained peripheral ischaemia resulting from meningococcal septicaemia and to assess the benefit of fasciotomies within this group.

Introduction: There have been only two published series on the orthopaedic management of meningococcal septicaemia in children. We carried out a retrospective review of all patients who had undergone this intervention in RHSC.

Methods: Between 1994 and 2004 there were 190 admissions to paediatric intensive care unit (PICU) with meningococcal septicaemia. 12 had significant Orthopaedic/Plastic Surgical input. Case notes were examined to establish admission patterns, limb progress, subsequent operative intervention and eventual outcomes.

All presented with vague viral symptoms and developed rapidly spreading purpuric rashes within 24hours. 8 children were admitted from A& E and 4 were transferred from other hospitals. All received antibiotics, fluid resuscitation, ventilation and inotropic support. One child died within 14 hours of PICU admission. Haemofiltration was used in 11 children (mean 14.8 days, range 2–60 days).

We were able to follow up 8 of the survivors clinically.

Results: All children had some form of surgical treatment. 9 children had one or more amputations. Two children did not require amputations. Seven of the 12 children had fasciotomies performed (mean 34 hours after admission, range 2–96 hours). The child who died from overwhelming sepsis had multiple fasciotomies at 9 hours post admission. The remaining children had varying amputations. The other five children did not have fasciotomies. Of these one child did not require any amputations, three children had partial amputation of a single limb and one child had partial amputations of two limbs. All five within this group required additional split-skin grafts.

8 children were followed clinically. 7 were mobile with walking aids with a mean of 1.3 prosthetic lower limbs (range 0–2).

Conclusion: There is no evidence from our study that early fasciotomies are detrimental to survival, limb function or subsequent wound healing after definitive amputation. In other published series fasciotomy has been advocated within 24hours.

In our study 2 of our 7 patients who underwent fasciotomy the demarcation level receded distally post decompression leading to more distal amputation levels.

In 2 of 7 patient, after fasciotomy the demarcation level receded distally leading to more distal amputation levels.

Purpose: The purpose of this work was to study the radiological outcome more than seven years after implantation of 89 anatomic non-cemented femoral stems with hydroxyapatite coating around the metaphyseal circumference.

Material: These 81 patients underwent primary arthroplasty (89 hips) between 1991 and 1994 for joint degeneration or necrosis: 48 men and 33 women, mean age 59 years (range 41–78). The inclusion criteria for this study were physical examination and complete radiographic work-up in the second half of 2001. Mean follow-up was nine years (range 7–10).

Methods: All x-rays were analysed by four independent surgeons who used the Engh and Massin criteria. The evaluators, who had not participated in patient care, made their assessment on the basis of the last follow-up clinical report and x-rays. They search for radiographic evidence of stem stability and bony integration as well as signs of osteolysis using the Gruen criteria.

Results: At last follow-up only one femoral stem was painful, but stable. This stem was revised at seven years. Six cups had been changed due to polyethylene wear with iliac osteolysis but without femoral participation. There were no other reoperations. Polyethylene wear was observed in about one-half the hips (44 hips) and was considered severe (1–2 mm) in nine cases. There were no lucent lines nor reactive lines in the metaphyseal area (zones 1 and 7) but 16% of the hips presented reactive lines along the lower, smooth, part of the stem. Endosteal ossification was observed in zones 2 and 6 in 72% of the hips, and less often (13%) in zones 9 and 13. Five hips (5.6%) exhibited bony growth at the tip of the stem producing a thickening in zone 5; these were the only cases with cortical thickening excepting the revised stem (thickening in zones 2 and 6). There was no case of cortical narrowing. Calcar atrophy was observed in 42 hips (47%) with five showing a “drop” aspect. Four hips exhibited osteolysis of the proximal femur in zone 1A, but there were no images of distal osteolysis of the femur.

Discussion: This independent analysis of 89 x-ray files demonstrated that endosteal growth is frequent in the isthmic region. The radiological tolerance was good for this stem (no cortical changes) but there were modifications of the calcar which were difficult; it could be speculated that certain of these modifications might correspond to localised osteolysis at the lowest part of the joint, migration point of polyethyene debris. The role of hydroxyapatite in the observed absence of distal osteolysis is noteworthy.

Conclusion: At nine years follow-up, the absence of osteolysis of the distal femur despite usual polyethylene wear allows the conclusion that hydoxyapatite coating of the metaphyseal circumference creates an effective barrier against wear debris.
