E-poster w/ Standard #954 Complications in Shoulder Arthroscopy in Athletes Benno Ejnisman, Sao Paulo, BRAZIL, Carlos Vicente Andreoli, Sao Paulo, BRAZIL Presenter Alberto Castro Pochini, Sao Paulo, BRAZIL Gustavo Cara Monteiro, Sao Paulo, BRAZIL Flavio Faloppa, Sao Paulo, BRAZIL Moises Cohen, Sao Paulo, BRAZIL Federal University of Sao Paulo, Sao Paulo, BRAZIL Introduction:Shoulder arthroscopy presents low morbidity when compare to the open procedures, however is not free of complications. Objective: To evaluate the incidence of complications of the arthroscopic procedures in the shoulder of athlete during intraoperative and postoperative period(1 year follow-up) Material: In the period of 1999 to the 2003, the authors had been evaluated and revised 320 shoulder arthroscopies of athlete with different pathologies, 72% wer male and 28 % were female. The average age was 24,2 years old. Results: 61 (19%) complications had been found, being that 38 (62,2%) intraoperative complications. In 19 cases breakage the suture during knot tying, 4 cases of reversion for the open procedure, 8 of anchor loosening, 5 cases of anchor brekage, 2 cases of salient anchor (intrarticular). According to postoperative complications, we found 23 (37,7%) case related to regular and fair results. The complications had been divided in: 8 cases of functional limitations in some range of motion (4 athletes with SLAP lesion, 4 cases involving frozen shoulder and subacromial pathology), 6 cases of residual pain, 5 cases of redislocation after stabilization, 2 cases of superficial infection and 1 case of condrolysis. We had solved the intraoperative complications in 94% of the cases and 88% of the postoperative complications. Conclusion: The arthroscopic surgery presents complications that could be managed in 94% of intraoperative and 88% of postoperative procedure. In shoulder arthroscopy complications, the surgeon should be skilled and have adequate surgical material. E-poster #955 Biceps Long Head to Conjoint Tendon Transfer Ronald M Selby, New York, NY, USA, Presenter Stephen J O'Brien, New York, NY USA Nick Verma, New York, New York USA Hospital for Special Surgery, New York, NY, USA This presentation will include the rationale, technique and 2 year follow up for patients undergoing biceps transfer. Comparison to a study of a peer group who underwent release of the long head of the biceps including a head-tohead comparison with validated instruments. A review of pertinent anatomy, literature review with historic approaches to the problem of bicipital tendonitis and partial tears, and presented for the first time recommendations for dynamic evaluation of the long head tendon. Video stepby-step presentation review of the technique with pertinent anatomic landmarks will be cited. Two year follow-up evaluations on the patient group with validated instruments will be presented. SPINE/HIP/THIGH E-poster #1000 Minimal Invasive Technique in Total Hip Arthroplasty, Short Term Results Tarik Aitsiselmi, Lyon, FRANCE, Presenter Srdan Dojcinovic, Lyon, FRANCE Sebastien Lustig, Lyon, FRANCE Philippe Neyret, Lyon, FRANCE Centre Livet, Croix Rousse, Lyon, FRANCE Aims: The purpose of this prospective study is to present our experience with a mini-incision technique for total hip arthroplasty with specific instrumentation and using commonly posterior surgical approach (Moore) and to evaluate technical and clinical results. Materiel and Method: 36 patients with mean age of 55 years were reviewed after 9 months to total hip arthroplasty through minimally invasive posterior approach. The mean BMI was 26.45. Underlying diseases were: 24 primary arthrosis, 7 avascular necrosis, 5 inflammatory disease and 1 fracture of the hip neck. An analysis of complications, the length of hospital stay, radiographic position of prosthetic components as well as of clinical status at followup using scores by Harris, Womac and Merle Aubign was performed. Results: Complications were one fracture of acetabular rim requiring screws and one instability of socket and was immediately revised. The mean blood loss
was 477 ml. The duration of operation was 88 min. The average length of the scar 66mm(+/-8). The visual analog scale was 2.5 at day 1, 1.5 at day 2 and 1.18 at day 3. The length of stay was 8 days. We don’t have any postoperative neuropathy or dislocation. A significant increase in a mean of Harris and Merle Aubign scores were observed, respectively from 57 to 82 and from 11 to 15 and decrease of score of Womac of 40 points. Average abduction of cup was 43 (+/-6). The femoral stems were in 1.2 (+/- 1.81) varus position. There is no discrepancy of length more than 5 mm. Conclusions: This study confirms that the mini-incision technique and specific instrumentation allows a good positioning of prosthetic components, this been one of the primary objectives of total hip arthroplasty without lengthen the duration of operation. There are several contraindications for this mini-incision technique which include obesity, severe dyplasia, malunions and arthrodesis of the hip. Esthetically the scar is more pleasing, which is important in our society. This technique seems to give good preliminary results and encourages us to go on with technique E-poster #1001 A Case of OS Odontoideum Incidentally Detected by Sports Medical Check Hitoshi Abe, Minato-ku, JAPAN, Yasunori Tsukimura, Minato, Tokyo, JAPAN Shoei Takeshima, Minato, Tokyo, JAPAN Masaki Nagashima, Minato, Tokyo, JAPAN Morio Matsumoto, Shinjyuku, Tokyo, JAPAN Hideo Matsumoto, Tokyo, JAPAN Kazuhiro Chiba, Shinjuku,Tokyo, JAPAN Yoshiaki Toyama, Shinjyuku, Tokyo, JAPAN Orshopaedic Depart. of Kitasato Institute Hospital, Minato, Tokyo, JAPAN [purpose] Os odontoideum is considered to be congenital or secondary to odontoid fracture. We experienced a case of os odontoideum incidentally detected by sports medical check. [case] Sixteen-year-old boy had played rugby for three years and had occasionally felt numbness in the upper and lower extremities when he was tackled. He had an episode of transient quadriparesis, but no medical investigation was conducted at that time. When he joined a high school rugby team, he underwent obligatory sports medical check. Os odontoideum was found on plain radiograph. He was referred to our hospital for further investigation and treatment. At the time of initial examination, he had no symptom at all, and neurological examination revealed no abnormality. On X rays, os odontoideum was evident, and atlantodental interval in flexion was 12mm. This anterior subluxation was perfectly reduced by extension of the neck. On MRI, compression of the spinal cord was not observed. Because of marked atlantoaxial instability and of history of transient quadriparesis, surgery was deemed to be necessary and performed on March 13, 2003. The operation was performed by the Magerl and Brooks method. Instability between C1/2 was remarkable, but rigid fixation of the atlantoaxial joint was achieved by transarticular screwing and sublaminar wiring. One year after surgery, solid arthrodesis was obtained, and the patient had no pain or neurological abnormality. However, ranges of neck motion were reduced to the halves of preoperative values. [Discussions] The etiology and choice of treatment of os odontoideum are controversial. Patients of os odontoideum with no or mild symptoms are sometimes found incidentally by radiographic examination taken after mild trauma or at medical checks as was this case. In the present case, the sports medical check was extremely useful, preventing the patient from catastrophic neurological damage. Since the patient had a history of transient quadriparesis and remarkable instability on flexion-extension X- rays, atlantoaxial arthrodesis was thought to be mandatory. Return to rugby play after surgery was also a matter of controversy. Although the patient achieved solid bone union, he was not allowed to return to rugby play because his limited neck motion might make his cervical spine more vulnerable to trauma due to hard contusion to the neck during rugby play.
