United Kingdom National Institute for Health
and Clinical Excellence guidelines recommend the use of total hip replacement
(THR) for displaced intracapsular fractures of the femoral neck
in cognitively intact patients, who were independently mobile prior
to the injury. This study aimed to analyse the risk factors associated
with revision of the implant and mortality following THR, and to
quantify risk. National Joint Registry data recording a THR performed
for acute fracture of the femoral neck between 2003 and 2010 were
analysed. Cox proportional hazards models were used to investigate
the extent to which risk of revision was related to specific covariates.
Multivariable logistic regression was used to analyse factors affecting
peri-operative mortality (<
90 days). A total of 4323 procedures
were studied. There were 80 patients who had undergone revision
surgery at the time of censoring (five-year revision rate 3.25%, 95%
confidence interval 2.44 to 4.07) and 137 patients (3.2%) patients
died within 90 days. After adjusting for patient and surgeon characteristics,
an increased risk of revision was associated with the use of cementless
prostheses compared with cemented (hazard ratio (HR) 1.33, p = 0.021).
Revision was independent of bearing surface and head size. The risk
of mortality within 90 days was significantly increased with higher
American Society of Anesthesiologists (ASA) grade (grade 3: odds
ratio (OR) 4.04, p <
0.001; grade 4/5: OR 20.26, p <
0.001;
both compared with grades 1/2) and older age (≥ 75 years: OR 1.65,
p = 0.025), but reduced over the study period (9% relative risk reduction
per year). THR is a good option in patients aged <
75 years and with
ASA 1/2. Cementation of the femoral component does not adversely
affect peri-operative mortality but improves survival of the implant
in the mid-term when compared with cementless femoral components.
There are no benefits of using head sizes >
28 mm or bearings other
than metal-on-polyethylene. More research is required to determine
the benefits of THR over hemiarthroplasty in older patients and
those with ASA grades >
2.
A vertical scapular osteotomy was first described by Wilkinson in 1980. We report six children with a mean age of 9 years 6 months at operation (range 4–16). Mean abduction pre-operatively was 77 degrees (range 70–160 degrees). Cosmetically all were Cavendish grade three except one grade four. Five of the six had associated abnormalities of the cervical spine (three Klippel-Feil and one hemivertebra) and four had omovertebral bars. One boy had a full range of movement pre-op and had a cosmetic correction. One girl had a preceding Erbs palsy which had resolved completely prior to surgery. Mean follow-up is five years (range 1–12 years). All patients have an excellent cosmetic result, four graded Cavendish one, two graded two, and one grade three. Mean abduction improved to 148 degrees and mean improvement was 77 degrees. Sprengel’s deformity presents significant cosmetic and functional deficits. We have found the vertical scapular osteotomy as described by Wilkinson a simple and reliable procedure with predictably good results. With regards to the omovertebral bone, we concur that its presence has no influence on functional outcome. Cosmetically, when clothed, the result is excellent, with the shoulders level. Undressed, however, asymmetry is still obvious with a truncated shoulder girdle and persistence of some webbing or fullness in the base of the neck. This appears more marked when an omovertebral bone was present. We conclude that a vertical scapular osteotomy is a reliable operation for improving shoulder girdle function, but that cosmetic objectives must be reliable.
