Aim: Hip fracture is the most devastating outcome of osteoporosis with high early mortality. Less is known about men in terms of long-term survival and fracture risk, information of outmost importance in terms of strategies for fracture prevention. The aim of this study was to evaluate long-term survival, new fractures and residual life time risk of fracture in a cohort of men with hip fracture in different ages. This is the first study with a follow-up above 10 years.

Methods: All men above 20 yrs of age suffering a hip fracture 1984–1985 in Malmö, Sweden were identified and followed up to 22 years or death. All new radiographic examinations related to musculoskeletal trauma with or without fracture were individually registered. Survival and fractures were evaluated in 5-year age bands and age-groups (< 75, 75–84 and ≥85 years). Kaplan Meier survival analyses were used to evaluate mortality and fracture risk.

Results: 263 men (74.2 yrs, range 33–101) with an index hip fracture due to low energy trauma were identified. 56% had cervical fractures and 44% trochanteric with 6% having concomitant fractures. 10 % had suffered a previous hip fracture. After 22 years 94% were dead; 32 % within 1 yr, 62% within 5 yrs and 79% within 10yrs. Mean age at death was 80.1 yr (range 41–101), equal to a mean of 5.8 yrs above the mean age for fracture. The 50% survival in respectively age groups < 75, 75–84 and ≥ 85 years was 7 yrs, 2 yrs and 3 months. 74/263 (28%) suffered totally 131 fractures (1.8, range 1–7 fractures/patient) at 121 occasions. The majority suffered only a new fracture at one occasion (n=48, 65%). 14% of the fracture occasions occurred within 1 yr and half of the fractures occurred within 3.2 yrs. Mortality adjusted life time risk of fracture was 62% and 10-year risk of fracture was 47%.

Conclusion: In this study we report fracture risk and mortality in a residual life time perspective in men after hip fracture. Men suffer hip fractures earlier in life and have, compared to women from the same cohort, higher early mortality (32% resp 21% (1 yr)) and lower residual lifetime risk of fracture (28% resp 45%)¹. The high early mortality probably mirrors a higher morbidity among male hip fracture patients. The consequence is that fracture preventing strategies need to consider both gender, age and mortality.

Background: The Hansson Twin Hook (HTH) is an alternative to the sliding hip screw in the treatment of trochanteric fractures. In osteoporotic bone, biomechanical tests indicate better fixation properties of the HTH than of the lag screw. Our aim was to evaluate the technical results of the HTH in a larger series of osteoporotic patients with intertrochanteric fractures. Many surgeons were involved to assess, if the device was user-friendly.

Patients and Methods: In a prospective bicentric study, 55 surgeons used the HTH and a standard plate in 157 consecutive patients with intertrochanteric fractures, of which 83% were unstable. The mean age of the patients was 83 years. The patients were followed regularly clinically and radiographically for at least 4 months with a final control at 2 years.

Results: Technical intraoperative errors were done in 7 of the patients. The reduction of the fracture was inaccurate in these cases; hence the HTH had not been placed centrally in the femoral head. Two of the 7 intraoperative errors developed into failures of fixation (1.3%) during the 2-year period.

Interpretation: The HTH achieves adequate fixation purchase in osteoporotic bone, has a low failure rate and is easy to use.

Introduction: The C-stem (DePuy, Leeds, UK) is triple tapered, polished and collarless. These features can facilitate distal stem migration within the cement mantle, a phenomenon first noticed on radiographs and later confirmed by radiostrereometric analysis (RSA) for the double tapered polished Exeter stem (Stryker, Mahwah, NJ). Low revision rates are reported for the Exeter stem and the view that early migration predicts later failure has not been confirmed with double tapered designs. If a triple tapered stem has any advantages is however not known

Patients and methods: 33 primary hip arthroplasties with a median age of 66 (46–74) years were followed for 2 years with radiostereometric analysis (RSA) at 3 months, 6 months, 1, 2 and 3 years. The diagnosis was primary osteoarthrosis in all hips. Both migration and rotation were studied.

Results: All the stems migrated distally and posteriorly within the cement mantle. The median distal migration was 1.47 mm at 3 years and the median posterior migration was 1.56 mm at 3 years. All the stems rotated towards retroversion and median rotation at 3 years was 2.0°. For all the other directions the prosthesis was stable up to 3 years

Discussion: The C-stem migrates and rotates more than cemented prostheses of other designs. Compared with other tapered prostheses the distal migration is at the same level but posterior rotation is higher and furthermore it migrates posteriorly, which the other tapered stems do not. If this migration/rotation pattern is tolerable without risk of prosthetic failure needs to be studied further, but at present there is no indication from the available clinical results for the C-Stem that this pattern is deleterious.

25 RA patients with their ankles fused with an intramedullary nail were compared to 35 RA patients with their ankles fused with compression screws.

24/25 nailed patients showed radiographic healing at follow-up after 3 (1–8) years, and 26/35 ankles in the compression screw group examined after 6 (1–14) years healed after the first attempt and another 5 after repeat surgery.

In the nailed group 23 patients were satisfied and 2 somewhat satisfied. In the compression screw group 20 were satisfied, 12 somewhat satisfied and 3 dissatisfied.

There were 4 deep infections (3 healed after nail extraction and antibiotics, one unhealed) in the nail group and 1 deep infection (healed after antibiotics) in the compression screw group.

Six patients in the nailed group also had a permanent plantar sensory loss.

Conclusion: Ankle fusion with retrograde intramedullary nailing seems to result in a high rate of healing and satisfied patients, but cares a substantial risk of deep infection compared to fusion with compression screws, which has a lower fusion rate fewer satisfied patients, but less complications.

RA patients with a normal subtalar joint are of course only managed by compression screws.
