Patients with longstanding hip fusion are predisposed to symptomatic degenerative changes of the lumbar spine, ipsilateral knee and contralateral hip. 1. In such patients, conversion of hip arthrodesis to hip replacement can provide relief of such symptoms. 2 – 4. However, this is a technically demanding procedure associated with higher complication and failure rates than routine total hip replacement. The aim of this study was to determine the functional results and complications in patients undergoing hip fusion conversion to total hip replacement, performed or supervised by a single surgeon. Twenty-eight hip fusions were converted between 1996 and 2016. Mean follow up was 7 years (3 to 18 years). The reasons for arthrodesis were trauma 11, septic arthritis 10, and dysplasia 7. The mean age at conversion was 52.4 years (26 to 77). A trochanteric osteotomy was performed in all hips. Uncemented components were used. A constrained liner was used in 7 hips. Heterotopic ossification prophylaxis was not used in this series. HHS improved a mean of 27 points (37.4 pre-op to 64.3 post-op). A cane was used in 30% of patients before conversion and 80% after. Heterotopic ossification occurred in 12 (42.9%) hips. There was 2
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). 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.Aims
Methods
A possible solution for the management of proximal femoral bone
loss is a modular femoral endoprosthesis (EPR). Although the outcome
of EPRs in tumour surgery has been well described, the outcome of
their use in revision hip surgery has received less attention. The
aim of this study was to describe the outcome of using EPR for non-neoplastic
indications. A retrospective review of 79 patients who underwent 80 EPRs for
non-neoplastic indications was performed, including the rates of
complication and survival and the mean Oxford Hip Scores (OHS),
at a mean of five years post-operatively. The mean age at the time
of surgery was 69 years (28 to 93) and the mean number of previous operations
on the hip was 2.4 (0 to 17). The most common indications for EPR
implantation were periprosthetic joint infection (PJI) (n = 40),
periprosthetic fracture (n = 12) and failed osteosynthesis of a
proximal femoral fracture or complex trauma (n = 11).Objectives
Methods
Eighteen hip fusions were converted to total
hip replacements. A constrained acetabular liner was used in three hips.
Mean follow up was five years (two to 15). Two (11%) hips failed,
requiring revision surgery and two patients (11%) had
