Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

Twenty-three patients with thirty hips of slipped capital femoral epiphysis were treated in our department, KK Women's and Children's Hospital, Singapore between 1997 and 2005. Except one patient lost of follow-up, twenty-four SCFEs with more than 2 years (25 to 73 months, average 38.5 months) follow-up were reviewed. This study is to evaluate the effectiveness and outcome of our protocol: Russell traction followed by gentle manipulative reduction with a single screw fixation & spica cast immobilization (for acute-on-chronic cases with unstable and reducible SCFE). In this series, there were 13 boys & 5 girls, mean age 12 year old ranging from 10 to 14 years. Among them 7 were Chinese, 6 Malays & 5 Indians. There were 12 unilateral cases (8 on the left & 4 right, 67%) & 6 bilateral cases (33%), including 2 patients found contralateral SCFE subsequently 1 year postoperatively. Acute-on-chronic SCFE were 16 & chronic SCFE 8. 16 were Grate I & 8 Grate II. Russell traction was on preoperatively with an average of 6 days. Gentle manipulative reduction under general anesthesia was performed in 20 SCFEs (12 GI & 8 GII) and 17 of them were successful. Fixation with a single screw was used for all cases except one hip with 2 screws. Average follow-up was 38.5 months. Good results achieved. All patient were symptom free with good function. No complications of AVN, chondrolysis, screw loosening and reslipping of the affective hips. Our protocol of management for SCFE has been largely successful in term of manipulative reduction and fixation

Aims

This study aims to estimate economic outcomes associated with 30-day deep surgical site infection (SSI) from closed surgical wounds in patients with lower limb fractures following major trauma.

Aims

Monocyte-lymphocyte ratio (MLR) or neutrophil-lymphocyte ratio (NLR) are useful for diagnosing periprosthetic joint infection (PJI), but their diagnostic values are unclear for screening fixation-related infection (FRI) in patients for whom conversion total hip arthroplasty (THA) is planned after failed internal fixation for femoral neck fracture.

We evaluated the outcome of treatment of nonunion of an intracapsular fracture of the femoral neck in young patients using two cannulated screws and a vascularised bone graft. A total of 32 patients (15 women and 17 men, with a mean age of 36.5 years; 20 to 50) with failed internal fixation of an intracapsular fracture were included in the study. Following removal of the primary fixation, two cannulated compression screws were inserted with a vascularised iliac crest bone graft based on the ascending branch of the lateral femoral circumflex artery.

At a mean follow-up of 6.8 years (4 to 10), union was achieved in 27 hips (84%). A total of five patients with a mean age of 40.5 years (35 to 50) had a persistent nonunion and underwent total hip arthroplasty as also did two patients whose fracture united but who developed osteonecrosis of the femoral head two years post-operatively. Statistical analysis showed that younger patients achieved earlier and more reliable union (p < 0.001). The functional outcome, as assessed by the Harris Hip score, was better in patients aged < 45 years compared with those aged > 45 years (p < 0.001).

These findings suggest that further fixation using two cannulated compression screws and a vascularised iliac crest bone graft is an effective salvage treatment in patients aged <  45 years, in whom osteosynthesis of a displaced intracapsular fractures of the femoral neck has failed.

There have been recent reports linking alendronate and a specific pattern of subtrochanteric insufficiency fracture. We performed a retrospective review of all subtrochanteric fractures admitted to our institution between 2001 and 2007. There were 20 patients who met the inclusion criteria, 12 of whom were on long-term alendronate. Alendronate-associated fractures tend to be bilateral (Fisher’s exact test, p = 0.018), have unique radiological features (p < 0.0005), be associated radiologically with a pre-existing ellipsoid thickening of the lateral femoral cortex and are likely to be preceded by prodromal pain. Biomechanical investigations did not suggest overt metabolic bone disease. Only one patient on alendronate had osteoporosis prior to the start of therapy. We used these findings to develop a management protocol to optimise fracture healing. We also advocate careful surveillance in individuals at-risk, and present our experience with screening and prophylactic fixation in selected patients.

Although supracondylar fracture is a very common elbow injury in childhood, there is no consensus on the timing of surgery, approach for open reduction and positioning of fixation wires. We report our ten-year experience between 1993 and 2003 in 291 children.

Most fractures (285; 98%) were extension injuries, mainly Gartland types II (73; 25%) and III (163; 56%). Six (2%) were open fractures and a neurovascular deficit was seen in 12 (4%) patients. Of the 236 children (81%) who required an operation, 181 (77%) were taken to theatre on the day of admission. Most (177; 75%) of the operations were performed by specialist registrars. Fixation was by crossed Kirschner wires in 158 of 186 (85%) patients and open reduction was necessary in 52 (22%).

A post-operative neurological deficit was seen in nine patients (4%) and three (1%) required exploration of the ulnar nerve. Only 22 (4%) patients had a long-term deformity, nine (3%) from malreduction and three (1%) because of growth arrest, but corrective surgery for functional limitation was required in only three (1%) patients.
