In a randomised controlled pragmatic trial we
investigated whether local infiltration analgesia would result in earlier
readiness for discharge from hospital after total knee replacement
(TKR) than patient-controlled epidural analgesia (PCEA) plus femoral
nerve block. A total of 45 patients with a mean age of 65 years
(49 to 81) received a local infiltration with a peri-articular injection
of bupivacaine, morphine and methylprednisolone, as well as adjuvant
analgesics. In 45 PCEA+femoral nerve blockade patients with a mean
age of 67 years (50 to 84), analgesia included a bupivacaine nerve
block, bupivacaine/hydromorphone PCEA, and adjuvant analgesics.
The mean time until ready for discharge was 3.2 days (1 to 14) in
the local infiltration group and 3.2 days (1.8 to 7.0) in the PCEA+femoral
nerve blockade group. The mean pain scores for patients receiving
local infiltration were higher when walking (p = 0.0084), but there
were no statistically significant differences at rest. The mean
opioid consumption was higher in those receiving local infiltration. The choice between these two analgesic pathways should not be
made on the basis of time to discharge after surgery. Most secondary
outcomes were similar, but PCEA+femoral nerve blockade patients
had lower pain scores when walking and during continuous passive
movement. If PCEA+femoral nerve blockade is not readily available, local
infiltration provides similar length of stay and similar pain scores
at rest following TKR. Cite this article:

Aims. Brace treatment is the cornerstone of managing developmental dysplasia of the hip (DDH), yet there is a lack of evidence-based treatment protocols, which results in wide variations in practice. To resolve this, we have developed a comprehensive nonoperative treatment protocol conforming to published consensus principles, with well-defined a priori criteria for inclusion and successful treatment. Methods. This was a single-centre, prospective, longitudinal cohort study of a consecutive series of infants with ultrasound-confirmed DDH who underwent a comprehensive nonoperative brace management protocol in a unified multidisciplinary clinic between January 2012 and December 2016 with five-year follow-up radiographs. The radiological outcomes were acetabular index-lateral edge (AI-L), acetabular index-sourcil (AI-S), centre-edge angle (CEA), acetabular depth ratio (ADR), International Hip Dysplasia Institute (IHDI) grade, and evidence of avascular necrosis (AVN). At five years, each hip was classified as normal (< 1 SD), borderline dysplastic (1 to 2 SDs), or dysplastic (> 2 SDs) based on validated radiological norm-referenced values. Results. Of 993 infants assessed clinically and sonographically, 21% (212 infants, 354 abnormal hips) had DDH and were included. Of these, 95% (202 infants, 335 hips) successfully completed bracing, and 5% (ten infants, 19 hips) failed bracing due to irreducible hip(s). The success rate of bracing for unilateral dislocations was 88% (45/51 infants) and for bilateral dislocations 83% (20/24 infants). The
The modified Smith–Petersen and Kocher–Langenbeck
approaches were used to expose the lateral cutaneous nerve of the
thigh and the femoral, obturator and sciatic nerves in order to
study the risk of injury to these structures during the dissection,
osteotomy, and acetabular reorientation stages of a Bernese peri-acetabular
osteotomy. Injury of the lateral cutaneous nerve of thigh was less likely
to occur if an osteotomy of the anterior superior iliac spine had
been carried out before exposing the hip. The obturator nerve was likely to be injured during unprotected
osteotomy of the pubis if the far cortex was penetrated by >
5 mm.
This could be avoided by inclining the osteotome 45° medially and
performing the osteotomy at least 2 cm medial to the iliopectineal
eminence. . The sciatic nerve could be injured during the first and last
stages of the osteotomy if the osteotome perforated the lateral
cortex of ischium and the ilio-ischial junction by >

Dual-mobility acetabular components (DMCs) have improved total hip arthroplasty (THA) stability in femoral neck fractures (FNFs). In osteoarthritis, the direct anterior approach (DAA) has been promoted for improving early functional results compared with the posterolateral approach (PLA). The aim of this study was to compare these two approaches in FNF using DMC-THA. A prospective continuous cohort study was conducted on patients undergoing operation for FNF using DMC by DAA or PLA. Functional outcome was evaluated using the Harris Hip Score (HHS) and Parker score at three months and one year. Perioperative complications were recorded, and radiological component positioning evaluated.Aims

Aims. To establish whether there was a consensus among the members of the Hip Society (HS) on the role of direct anterior approach (DAA) contemporary primary total hip arthroplasty (THA). Methods. An online survey was sent to all 112 active and senior members of the HS, to which 71 members responded. The survey was constructed to determine whether they believed that evidence-based medicine proves, in modern clinical practice, that the DAA has significant benefits compared to risks when contrasted with other approaches. In addition, they were asked if they currently used the DAA. Results. While only 16.9% (12/71) of respondents had been trained in a generic anterior approach during residency, 49.3% (35/71) had used the DAA in their clinical practice in the past or were using it at the present time. Unexpectedly, 42.9% (15/35) of respondents who had used the DAA in the past had abandoned it by the time of this survey. Only 22.5% (16/71) of all respondents believed that evidence-based medicine proves that the DAA has significant benefits compared to risks in contrast to other approaches. Conclusion. A comprehensive literature review found only three prospective randomized clinical trials (RCT) comparing the DAA with another approach with greater than one-year follow-up. Two showed minor benefits within the early postoperative period only, and one of those showed poorer mid-term results. Most of the published comparison studies with short follow-up show longer surgical times and greater blood loss for the DAA, and many three-month comparison studies show higher complication rates for the DAA using a proprietary traction table. The complications included problems with wound healing, lateral
This study reports mid-term outcomes after periacetabular osteotomy (PAO) exclusively in a borderline hip dysplasia (BHD) population to provide a contrast to published outcomes for arthroscopic surgery of the hip in BHD. We identified 42 hips in 40 patients treated between January 2009 and January 2016 with BHD defined as a lateral centre-edge angle (LCEA) of ≥ 18° but < 25°. A minimum five-year follow-up was available. Patient-reported outcomes (PROMs) including Tegner score, subjective hip value (SHV), modified Harris Hip Score (mHHS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were assessed. The following morphological parameters were evaluated: LCEA, acetabular index (AI), α angle, Tönnis staging, acetabular retroversion, femoral version, femoroepiphyseal acetabular roof index (FEAR), iliocapsularis to rectus femoris ratio (IC/RF), and labral and ligamentum teres (LT) pathology.Aims

When performing total hip replacement (THR) in high dislocated hips, the presence of soft-tissue contractures means that most surgeons prefer to use a femoral shortening osteotomy in order to avoid the risk of neurovascular damage. However, this technique will sacrifice femoral length and reduce the extent of any leg-length equalisation. We report our experience of 74 THRs performed between 2000 and 2008 in 65 patients with a high dislocated hip without a femoral shortening osteotomy. The mean age of the patients was 55 years (46 to 72) and the mean follow-up was 42 months (12 to 78). All implants were cementless except for one resurfacing hip implant. We attempted to place the acetabular component in the anatomical position in each hip. The mean Harris hip score improved from 53 points (34 to 74) pre-operatively to 86 points (78 to 95) at final follow-up. The mean radiologically determined leg lengthening was 42 mm (30 to 66), and the mean leg-length discrepancy decreased from 36 mm (5 to 56) pre-operatively to 8.5 mm (0 to 18) postoperatively. Although there were four (5%) post-operative
