Our retrospective analysis reports the outcome of patients operated for slipped capital femoral epiphysis using the modified Dunn procedure. Results, complications, and the need for revision surgery are compared with the recent literature. We retrospectively evaluated 17 patients (18 hips) who underwent the modified Dunn procedure for the treatment of slipped capital femoral epiphysis. Outcome measurement included standardized scores. Clinical assessment included ambulation, leg length discrepancy, and hip mobility. Radiographically, the quality of epiphyseal reduction was evaluated using the Southwick and Alpha-angles. Avascular necrosis, heterotopic ossifications, and osteoarthritis were documented at follow-up.Aims
Methods
Fracture repair occurs by two broad mechanisms:
direct healing, and indirect healing with callus formation. The effects
of bisphosphonates on fracture repair have been assessed only in
models of indirect fracture healing. A rodent model of rigid compression plate fixation of a standardised
tibial osteotomy was used. Ten skeletally mature Sprague–Dawley
rats received daily subcutaneous injections of 1 µg/kg ibandronate
(IBAN) and ten control rats received saline (control). Three weeks
later a tibial osteotomy was rigidly fixed with compression plating.
Six weeks later the animals were killed. Fracture repair was assessed
with mechanical testing,
We hypothesized that the wide-awake local anaesthesia with no tourniquet (WALANT) technique is cost-effective, easy to use, safe, and reproducible, with a low learning curve towards mastery, having a high patient satisfaction rate. Furthermore, WALANT would be a suitable alternative for the austere and developing nation environments where lack of funds and resources are a common issue. This was a randomized control trial of 169 patients who required surgery for closed isolated distal radius fractures. The study was performed between March 2016 and April 2019 at a public sector level 1 trauma centre. General anaesthesia was used in 56 patients, Bier’s block in 58 patients, and WALANT in 55 patients. Data were collected on pre-, peri-, and postoperative parameters, clinical outcome, hospital costs, and patient satisfaction. One-way analysis of variance (ANOVA) was used with a p-value of 0.05 being significant.Aims

This paper aims to review the evidence for patient-related factors associated with less favourable outcomes following hip arthroscopy. Literature reporting on preoperative patient-related risk factors and outcomes following hip arthroscopy were systematically identified from a computer-assisted literature search of Pubmed (Medline), Embase, and Cochrane Library using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and a scoping review.Aims

The primary aim of this study was to evaluate the efficacy of distension arthrography in the treatment of adhesive capsulitis of the shoulder. The secondary aim was to assess which patient and procedural factors predicted the recurrence of symptoms after the procedure. All patients referred to our shoulder clinic over a ten-year period, between 2008 and 2018, with a clinical diagnosis of capsulitis and symptoms persisting for more than six months, were offered treatment with a distension arthrogram. All procedures were performed by one of five musculoskeletal radiologists, with a combination of steroid, local anaesthetic, and a distention volume of 10 ml, 30 ml, or 50 ml. Patient demographics, procedural details, recurrence of symptoms, and the need for further intervention were evaluated.Aims

When the present study was initiated, we changed the treatment for late-detected developmental dislocation of the hip (DDH) from several weeks of skin traction to markedly shorter traction time. The aim of this prospective study was to evaluate this change, with special emphasis on the rate of stable closed reduction according to patient age, the development of the acetabulum, and the outcome at skeletal maturity. From 1996 to 2005, 49 children (52 hips) were treated for late-detected DDH. Their mean age was 13.3 months (3 to 33) at reduction. Prereduction skin traction was used for a mean of 11 days (0 to 27). Gentle closed reduction under general anaesthesia was attempted in all the hips. Concurrent pelvic osteotomy was not performed. The hips were evaluated at one, three and five years after reduction, at age eight to ten years, and at skeletal maturity. Mean age at the last follow-up was 15.7 years (13 to 21).Aims

Transarticular screw fixation with autograft
is an established procedure for the surgical treatment of atlantoaxial instability.
Removal of the posterior arch of C1 may affect the rate of fusion.
This study assessed the rate of atlantoaxial fusion using transarticular
screws with or without removal of the posterior arch of C1. We reviewed
30 consecutive patients who underwent atlantoaxial fusion with a
minimum follow-up of two years. In 25 patients (group A) the posterior
arch of C1 was not excised (group A) and in five it was (group B).
Fusion was assessed on static and dynamic
We report the results at a mean of 24.3 years
(20 to 32) of 61 previously reported consecutive total hip replacements carried
out on 44 patients with severe congenital hip disease, performed
with reconstruction of the acetabulum with an impaction grafting
technique known as cotyloplasty. The mean age of the patients at
operation was 46.7 years (23 to 68) and all were women. The patients
were followed post-operatively for a mean of 24.3 years (20 to 32), using
the Merle d’Aubigné and Postel scoring system as modified by Charnley,

Forearm fractures in children have a tendency
to displace in a cast leading to malunion with reduced functional
and cosmetic results. In order to identify risk factors for displacement,
a total of 247 conservatively treated fractures of the forearm in
246 children with a mean age of 7.3 years (. sd. 3.2; 0.9
to 14.9) were included in a prospective multicentre study. Multivariate
logistic regression analyses were performed to assess risk factors
for displacement of reduced or non-reduced fractures in the cast.
Displacement occurred in
73 patients (29.6%), of which 65 (89.0%) were in above-elbow casts.
The mean time between the injury and displacement was 22.7 days
(0 to 59). The independent factors found to significantly increase
the risk of displacement were a fracture of the non-dominant arm
(p = 0.024), a complete fracture (p = 0.040), a fracture with translation
of the ulna on lateral
This pilot study tested the performance of a rapid assay for diagnosing prosthetic joint infection (PJI), which measures synovial fluid calprotectin from total hip and knee revision patients. A convenience series of 69 synovial fluid samples from revision patients at the Norfolk and Norwich University Hospital were collected intraoperatively (52 hips, 17 knees) and frozen. Synovial fluid calprotectin was measured retrospectively using a new commercially available lateral flow assay for PJI diagnosis (Lyfstone AS) and compared to International Consensus Meeting (ICM) 2018 criteria and clinical case review (ICM-CR) gold standards.Aims

Pathological fractures in children can occur
as a result of a variety of conditions, ranging from metabolic diseases and
infection to tumours. Fractures through benign and malignant bone
tumours should be recognised and managed appropriately by the treating
orthopaedic surgeon. The most common benign bone tumours that cause pathological
fractures in children are unicameral bone cysts, aneurysmal bone
cysts, non-ossifying fibromas and fibrous dysplasia. Although pathological
fractures through a primary bone malignancy are rare, these should
be recognised quickly in order to achieve better outcomes. A thorough
history, physical examination and review of plain
The direct posterior approach with subperiosteal dissection of the paraspinal muscles from the vertebrae is considered to be the standard approach for the surgical treatment of adolescent idiopathic scoliosis (AIS). We investigated whether or not a minimally-invasive surgery (MIS) technique could offer improved results. Consecutive AIS patients treated with an MIS technique at two tertiary centres from June 2013 to March 2016 were retrospectively included. Preoperative patient deformity characteristics, perioperative parameters, power of deformity correction, and complications were studied. A total of 93 patients were included. The outcome of the first 25 patients and the latter 68 were compared as part of our safety analysis to examine the effect of the learning curve.Aims

Objectives. Small animal models of fracture repair primarily investigate
indirect fracture healing via external callus formation. We present
the first described rat model of direct fracture healing. Methods. A rat tibial osteotomy was created and fixed with compression
plating similar to that used in patients. The procedure was evaluated
in 15 cadaver rats and then in vivo in ten Sprague-Dawley
rats. Controls had osteotomies stabilised with a uniaxial external
fixator that used the same surgical approach and relied on the same
number and diameter of screw holes in bone. Results. Fracture healing occurred without evidence of external callus

In the majority of patients with slipped upper
femoral epiphysis only one hip is involved at primary diagnosis. However,
the contralateral hip often becomes involved over time. There are
no reliable factors predicting a contralateral slip. Whether or
not the contralateral hip should undergo prophylactic fixation is
a matter of controversy. We present a number of essential points
that have to be considered both when choosing to fix the contralateral
hip prophylactically as well as when refraining from surgery and
instead following the patients with repeat
It is unusual, if not unique, for three major research papers concerned with the management of the fractured neck of femur (FNOF) to be published in a short period of time, each describing large prospective randomized clinical trials. These studies were conducted in up to 17 countries worldwide, involving up to 80 surgical centers and include large numbers of patients (up to 2,900) with FNOF. Each article investigated common clinical dilemmas; the first paper comparing total hip arthroplasty versus hemiarthroplasty for FNOF, the second as to whether ‘fast track’ care offers improved clinical outcomes and the third, compares sliding hip with multiple cancellous hip screws. Each paper has been deemed of sufficient quality and importance to warrant publication in The Lancet or the New England Journal of Medicine. Although ‘premier’ journals, they only occationally contain orthopaedic studies and thus may not be routinely read by the busy orthopaedic/surgical clinician of any grade. It is therefore our intention with this present article to accurately summarize and combine the results of all three papers, presenting, in our opinion, the most important clinically relevant facts.

The consensus is that bipolar hemiarthroplasty (BHA) in allograft-prosthesis composite (APC) reconstruction of the proximal femur following primary tumour resection provides more stability than total hip arthroplasty (THA). However, no comparative study has been performed. In this study, we have compared the outcome and complication rates of these two methods. In a retrospective study, 57 patients who underwent APC reconstruction of proximal femur following the primary tumour resection, either using BHA (29) or THA (28), were included. Functional outcome was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and Harris Hip Score (HHS). Postoperative complications of the two techniques were also compared.Aims

During the pandemic of COVID-19, some patients with COVID-19 may need emergency surgeries. As spine surgeons, it is our responsibility to ensure appropriate treatment to the patients with COVID-19 and spinal diseases. A protocol for spinal surgery and related management on patients with COVID-19 has been reviewed. Patient preparation for emergency surgeries, indications, and contraindications of emergency surgeries, operating room preparation, infection control precautions and personal protective equipments (PPE), anesthesia management, intraoperative procedures, postoperative management, medical waste disposal, and surveillance of healthcare workers were reviewed. It should be safe for surgeons with PPE of protection level 2 to perform spinal surgeries on patients with COVID-19. Standardized and careful surgical procedures should be necessary to reduce the exposure to COVID-19.
