Introduction: Higher loosening rate, improvements in metalo n metal bearings and excellent immediate clinico-functional results related with current Standard total hip endoprosthesis, have suposed the rennaisance of the new hip resurfacing implants. In this work we present our experience the first 486 cases and minimal 5 years follow up.

Material and method: From July 2003 to December 2008 486 surface arthroplasties were implanted in our institution (4 bilateral) in 450 patients, 314 males y 136 females, mean age of 46,6 years (16 – 69). 9 BHR, 2 ASR, 3 ADEPT, 5 CORIN, 22 Mitch and 409 CONSERVE PLUS models were implanted. In 454 cases a modified Kocher-Langenbeck posterior approach and in 32 cases Hueter’s anterior approach were carried out. Surgical time, intraoperative bleeding and collected blood in drains, components orientation in AP radiographies, registered complications, Merle d’Aubigné, WOMAC and HHS clínico-funtcional scores were assessed. Statistical analysis was performed by means of chi-squared test and non – parametric tests.

Results: Mean surgical time was 1h 50’ (1h 15’ a 2h 30’), mean intraoperative bleeding 273,4 cc (210 – 360cc), drained blood 224,2 cc (180 – 380cc). During the first year 11 autodonated blood units were retransfused (during the first 5 months patients were encouraged for 1000cc. autodonation). Mean CCD angle was 139,7° (SD 130 – 147) and acetabular inclination 43° (SD 40 – 65°). There were 4 instances of femoral fractures during the first half year after surgery, which required conversiòn to a BFH total endoprosthesis, one too adducted cup (65°), which required only cup exchange. There was a very significant improvement in clinico-functional scores: MDA score improved from 12,9 pts. preoperative (11 – 14) to 17,4 at latest follow-up (15 – 18) (p< 0,001), WOMAC from 46,2 (19 – 67) to 93,2 (79 – 100) (p< 0,001) and HHS from 52,3 (range 42 – 60) to 96,7 (range 89 – 98) (p< 0,001). Main complications were 1 arterial femoral thrombosis, 1 deep venous thrombosis, 1 deep infection that required 2-stages exchange, 4 transient femoral pare-sia. Overall survivorship was 98,97%.

Conclusions: hip resurfacing implantation, when recommendations made by the first authors of these new models are properly carried out, provide excellent clinical-functional results, comparable to non cemented total hip implants, if not better. Longer follow up are required to assess more adequately these implants, although it will not probably mean in the majority of the cases any hip exchange of a standard THA in terms of morbidity and mid-longterm clinical-functional result. This assumption has been taken from our cases converted to a THA with BFH. For this reason we do think absolutely we dispose today a very promising implant for young adults with well stablished hip osteoarthritis.

Purpose: Some of nowadays treatments in shoulder pathology are focused in pain drop, but is to be evidenced than pain is the most reliable item in shoulder patient’s quality of life. The purpose of this study is to analyze quality of life in patients affected of different shoulder pathologies and check how pain and movement influence quality of life perception (QLP).

Material And Methods: 134 patients correctly filled the shoulder functional Constant score and the SF-36 score. Patients were classified by age, sex, labor status, level of education and diagnosis. There were 56 men (41,79%) and 78 women (58,21%). Mean age was 53,77 (18–85). Amongst them, 74 patients were classified as subacromial syndrome, 19 as fractures, 29 degenerative pathology and 12 as shoulder instability. Student’s T test was performed to study quantitative variables. Qualitive variables were studied using ANOVA test. Impact of pain and mobility on patients’ quality of life was assessed by Rho-Spearman’s test. Statistical regression coefficient was used to evaluate the impact of pain and mobility in perceived quality of life.

Results: There were statistically significant differences amongst age, sex and diagnosis groups (p< 0,001). Patients older than 65 years old significatively (p< 0.001) perceived worst quality of life. Women and patients affected by a degenerative disorder significatively perceived worst quality of life (p< 0.001). A relationship between movement and quality of life was founded (linear trend). In patients with preserved range of motion, changes in pain perception significatively affected PQL (p< 0,001), meanwhile patients with poor range of motion, changes in pain perception did not affect PQL (p> 0,001). The regression coefficient for pain related to SF-36 Physical component scale was 0,629 (IC: 0,301–0.958), meanwhile the regression coefficient for external rotation is 1,196 (IC: 0,693–1,699), giving thus a predominant effect of extenal rotation in PQL.

Conclusion/Discussion: Age, sex and etiology of shoulder disorder determine different perceptions of quality of life independently of the shoulder functional scoring.

Range of motion significatively affect QLP independently of the level of pain. Pain affects QLP in patients whom range of motion is preserved. External rotation is the most important item affecting QLP.

Factors determining quality of life perception should be taken into account when planning surgery strategies for different shoulder disorders.

Introduction. Prospective study based on professional sportsmen who affected from Chronicle Compartmental Syndrome in forearm and its treatment.

Material and methods. 32 Chronicle Compartmental Syndrome in forearm were studied in 24 patients. Our selection was composed by 16 men and 8 women. In 8 of our cases both forearms were operated. The age range was from 17 to 33 years of age. Their sportive activity included: 20 professional motorcyclists, 2 wind-surfers and 2 mountainbikers.

To demonstrate evidence of Chronicle Compartmental Syndrome we performed a diagnostic test based on the measure of the intracompartmental pressure after stimulating their usual sportive activity. We considered a positive test when the measured an IMP> 15 mmHg after effort. We also performed a dynamometric of their grip and strength of the thumb-index forceps before and after surgery.

Results. All 24 patients presented clinical and tests compatible with Chronicle Compartmental Syndrome in forearm during effort activities which reached severe range due to loss of sensibility and propioception.

- From 15 to 20 mmHg of IMP after effort, 8 cases.

Minimal invasive surgery based on fasciotomy was performed to release compartmental pressure in flexor and extensor compartments of the forearm.

Conclusions. We can conclude that after fasciotomy most of our patients improve either clinically and diagnostic tests results, without strength loss, and are able to return to their usual activity completely recovered in a short period of time

Introduction. Prospective comparative study to evaluate the efficacy of the ultrasound diagnosis vs MRI in rupture of the Triangular fibrocartilage with arthroscopic confirmation.

Material and methods. 55 patients presenting clinical wrist pain were studied from January’2004 untill september 2006. Our patient selection was composed by 30 men and 25 women, and the age range was 17 to 70 years old. 40 were Right-handed and 15 Left-Handed. Patients presented wrist pain related to several disorders. Our protocol included Sonography with a 11–MHz linear array probe using real-time compound spatial imaging and 1T-MRI studies. Wrist arthroscopy was performed in all of them.

Results. 67 % of our patients presented Triangular fibrocartilage rupture at arthroscopy. The distribution of our patients related to the complementary tests was:

- Arthroscopy (+) 37 cases out of 50 (64%)

According to this results we can easily calculate the sensibility/specificity and PPV/PNV of both tests:

- Ultrasound Sensibility/Specificity: 58,3 %/36,8 %

Conclusions. Due to the results we obtained in our study, we can consider ultrasound as sensible and specific as MRI at diagnosis for the rupture of the Triangular fibrocartilage. In our opinion we conclude that neither MRI nor ultrasound results should be considered satisfactory for a proper diagnosis. This could be sorted out by the use of more resolutive MRI and ultrasound equipments.
