Impact of Femoral Stem Design on Failure After Anterior Approach Total Hip Arthroplasty.

BACKGROUND: An increased rate of complications related to femoral component failure has been described with less invasive total hip arthroplasty (THA). This study evaluated the incidence of femoral complications associated with the direct anterior approach for THA. METHODS: Retrospective review was performed of the initial 1120 consecutive patients who underwent direct anterior THA by 2 surgeons. RESULTS: A total of 899 patients (80.3%) had a 2-year follow-up (range, 2-8 years). Complications within 90 days occurred in 20 patients (1.8%): 10 calcar fractures, 1 greater trochanter fracture, 1 canal perforation, 3 hematomas, 2 dislocations, 2 superficial, and 1 deep infection. Nine patients (1%) underwent revision: 5 for aseptic femoral loosening (0.55%), 1 for periprosthetic joint infection, 1 for dislocation, 1 for hip flexor irritation, and 1 for a damaged polyethylene liner. Of the 5 patients with aseptic femoral loosening, 3 had a short, mediolateral tapered stem, 1 cemented stem, and 1 S-ROM stem placed to bypass a canal perforation. There were no revisions for aseptic loosening in the collared, fully hydroxyapatite (HA)-coated compaction broached or triple tapered proximal fit and fill stem designs (70.6% of all stems). Revision rate for femoral loosening was significantly higher for tapered wedge over HA-coated, compaction broached stems (P < .005). CONCLUSION: Pain and function improved predictably with a 0.55% rate of femoral loosening at 2-year follow-up. Among collared, fully HA-coated and triple taper fit and fill femoral stems, there were no instances of revision for aseptic loosening vs 3 in the short stem, collarless mediolateral tapered group.

Muscle atrophy at diagnosis of carpal and cubital tunnel syndrome.

PURPOSE: This study was designed to test the hypothesis that patients with an initial diagnosis of cubital tunnel syndrome are more likely to present with muscle atrophy than patients with an initial diagnosis of carpal tunnel syndrome. METHODS: A list of patients presenting to the office of a single hand surgeon from January 2000 to June 2005 with an initial diagnosis of isolated, idiopathic carpal tunnel syndrome or cubital tunnel syndrome was generated from billing records. The medical records of 58 patients with cubital tunnel syndrome and 370 patients with carpal tunnel syndrome were reviewed for age, gender, diabetes, and presence of atrophy. RESULTS: Twenty-three of 58 patients with an initial diagnosis of cubital tunnel syndrome had atrophy compared with only 62 out 370 patients with an initial diagnosis of carpal tunnel syndrome. Multiple logistic regression revealed that age (odds ratio, 1.06; 95% CI, 1.04-1.08) and diagnosis (cubital tunnel patients were more likely than carpal tunnel patients to present with atrophy; odds ratio, 4.5; 95% CI, 2.7-8.6) were factors significantly associated with atrophy at presentation. CONCLUSIONS: Patients with carpal tunnel syndrome present earlier in the course of their disease than patients with cubital tunnel syndrome. Patients with cubital tunnel syndrome are more likely to present with muscle atrophy, reflecting advanced nerve damage that may not respond to surgery.

Attitudes of hand surgeons, hand surgery patients, and the general public regarding psychologic influences on illness.

PURPOSE: Psychologic influences on illness are well recognized but infrequently addressed in the interactions of hand surgeons and patients. This study assessed the attitudes of hand surgery patients and hand surgeons regarding psychologic influences on illness and compared their attitudes with those of the general population. METHODS: An 8-question survey regarding participant's attitudes toward psychologic influences on illness was given to the general public (people waiting in an airport), patients presenting to a hand surgery practice, and members of the American Society for Surgery of the Hand. RESULTS: A total of 474 surgeons, 85 patients, and 42 public participants completed the survey. There were no notable differences between patients and the general public, but the surgeons' attitudes were markedly different from both patients and the general public with respect to 4 items: the surgeons underestimated the openness of patients and the general public to discussing psychologic influences and willingness to see a psychologist or psychiatrist; and they were more supportive than the general public or patients regarding the opinion that the placebo effect reflects the strong influence of psychologic factors in healing and that psychologic stress often is expressed as a physical complaint. The distribution of patient responses showed 2 subgroups with respect to the idea that psychologic stress often is expressed as a physical complaint and with regard to willingness to see a mental heath professional, reflecting that a subset of patients with a hand illness may be resistant to these concepts. CONCLUSIONS: Hand surgery patients and the general public are not as aware of the psychologic influences on illness as are hand surgeons, but they are more willing to consider and discuss psychologic factors-and even psychologic treatment-than their surgeons realize. Surgeons' views may be colored by a few negative interactions with challenging patients, but a dialogue with our patients regarding the influence of psychologic issues on illness will be well received by most patients and may facilitate recovery.
