Cementless femoral stems must be correctly sized and well-seated to obtain satisfactory biological fixation. The change in sound that occurs during impaction of the femoral broach is said to indicate good fit, but this has not been widely studied. We set out to find whether the presence or absence of these sound changes could predict correct sizing. We recorded the sound generated during femoral broaching for 105 cementless total hip arthroplasties using the Corail stem. Four cases were excluded, leaving 101 recordings for analysis. There were 36 male patients and 65 female patients, with a mean age of 69.9 years (Aims

The designation German ‘Adam Bogen’ (arch) which is the used in the German literature as a description of the thick medial cortex of the femoral neck is incorrect. This arch was described by Robert Adams (1795-1871), who was an Irish anatomist and surgeon. Adams, Colles and Smith were outstanding surgeons who described

The aim of this study was to evaluate the outcomes of a salvage procedure using a 95° angled blade plate for failed osteosynthesis of atypical subtrochanteric femoral fractures associated with the long-term use of bisphosphonates. These were compared with those for failed osteosynthesis of subtrochanteric fractures not associated with bisphosphonate treatment. Between October 2008 and July 2016, 14 patients with failed osteosynthesis of an atypical subtrochanteric femoral fracture were treated with a blade plate (atypical group). Their mean age was 67.8 years (60 to 74); all were female. During the same period, 21 patients with failed osteosynthesis of a typical subtrochanteric fracture underwent restabilization using a blade plate (typical group). Outcome variables included the time of union, postoperative complications, Harris Hip Score, and Sanders functional rating scale.Aims

We have designed a modular cemented femoral component for revision of failed total hip arthroplasty in which deficiency of the proximal femur is such as to require a variable extrafemoral portion of the stem. We present the results of the first 74 operations in 72 patients; 56 of the patients had grade-3 or grade-4 femoral deficiency as defined by Gustilo and Pasternak and 24 had

Diabetes mellitus (DM) is known to impair fracture healing. Increasing evidence suggests that some microRNA (miRNA) is involved in the pathophysiology of diabetes and its complications. We hypothesized that the functions of miRNA and changes to their patterns of expression may be implicated in the pathogenesis of impaired fracture healing in DM. Closed transverse fractures were created in the femurs of 116 rats, with half assigned to the DM group and half assigned to the control group. Rats with DM were induced by a single intraperitoneal injection of streptozotocin. At post-fracture days five, seven, 11, 14, 21, and 28, miRNA was extracted from the newly generated tissue at the fracture site. Microarray analysis was performed with miRNA samples from each group on post-fracture days five and 11. For further analysis, real-time polymerase chain reaction (PCR) analysis was performed at each timepoint.Objectives
Methods
Modular or custom-made femoral components have been preferred
for total hip arthroplasty (THA) in patients with a history of Perthes’
disease because of the distortion in the anatomy of the proximal
femur. However, it has not been established whether a monobloc cementless
stem will fit the distorted proximal femur or whether the results
of the procedure are satisfactory in this group of patients. We reviewed 68 consecutive patients who had undergone THA for
childhood Perthes’ disease between June 2003 and December 2008.
There were 35 men and 33 women with a mean age of 48 years (16 to
73) at the time of index arthroplasty. Their mean body mass index
was 24.4 (18.3 to 32.9). Of the 68 hips, 32 were classified as Stulberg
class III and 36 as class IV. The mean pre-operative shortening
of the affected leg was 17.2 mm (5 to 34). The minimum follow-up
was five years (mean 8.5 years; 5.2 to 10).Aims

To evaluate the effect of a single early high-dose vitamin D
supplement on fracture union in patients with hypovitaminosis D
and a long bone fracture. Between July 2011 and August 2013, 113 adults with a long bone
fracture were enrolled in a prospective randomised double-blind
placebo-controlled trial. Their serum vitamin D levels were measured
and a total of 100 patients were found to be vitamin D deficient
(<
20 ng/ml) or insufficient (<
30 ng/mL). These were then
randomised to receive a single dose of vitamin D3 orally
(100 000 IU) within two weeks of injury (treatment group, n = 50)
or a placebo (control group, n = 50). We recorded patient demographics,
fracture location and treatment, vitamin D level, time to fracture
union and complications, including vitamin D toxicity. Outcomes included union, nonunion or complication requiring an
early, unplanned secondary procedure. Patients without an outcome
at 15 months and no scheduled follow-up were considered lost to
follow-up. The Aims
Patients and Methods
The primary aim of this study was to evaluate the performance
and safety of magnetically controlled growth rods in the treatment
of early onset scoliosis. Secondary aims were to evaluate the clinical
outcome, the rate of further surgery, the rate of complications,
and the durability of correction. We undertook an observational prospective cohort study of children
with early onset scoliosis, who were recruited over a one-year period
and followed up for a minimum of two years. Magnetically controlled
rods were introduced in a standardized manner with distractions
performed three-monthly thereafter. Adverse events which were both related
and unrelated to the device were recorded. Ten children, for whom
relevant key data points (such as demographic information, growth
parameters, Cobb angles, and functional outcomes) were available,
were recruited and followed up over the period of the study. There
were five boys and five girls. Their mean age was 6.2 years (2.5
to 10).Aims
