Introduction: Hip Surgical Dislocation (SHD) according the technique described by Ganz et al. is a safe and powerful tool to access intra-articular hip pathology in adults. Some indications may also arise in younger patients to correct slipped capital femoral epiphysis or femoral neck deformities

Materials and Methods: From 2004 to 2008 we have selected 45 patients on whom the procedure was done to treat femoroacetabular impingement (FAI). The average follow up time is 3 years, and patient mean age 26 years. The indications for SHD were:

mixed FAI in 26 cases,

42 hips where graded as Tönnis 0 and 2 as Tönnis 1. All patients where evaluated according to the non arthritic hip score (NAHS – McCarthy et all) before and after the surgery at 3, 6, 12, 24 and 36 months. Osyrix^® software was used to measure radiographic parameters. The numeric variables where treated using SPSS for windows (paired t student test).

Surgical Technique: In all 45 cases we did SHD, acetabular and/or femoral head neck junction trimming and labrum refixation. In half cases an anterior step trochanteric osteotomy was done and in 7 cases additional relative neck lengthening was performed.

Results: The average alfa angle measured in the standard crosstable view x ray was 72° before surgery and 36° after surgery (p=0,0001). The NAHS before surgery was 40,8 average: 9,71 – pain; 6,9 – symptoms; 9 – function and 6,9 – activities and after surgery 76,38 average (p= 0,0001) 17,5 – pain (p= 0,0001); 12,9 – symptoms (p= 0,0001); 16 - function (p= 0,0001) and 14,9 - activities (p= 0,0001). All patients improved motion, specially flexion, internal rotation (p= 0,0001). The results did not differ significantly in the patients who had a trochanteric anterior step osteotomy. One patient had a total hip replacement for ongoing osteoartrithis

We had no avascular necrosis so far and no neurovascular damage. Trochanteric screw removal was done in 3 cases for local irritation. We had 2 capsule adhesions, released shortly after using arthroscopy.

Conclusions: SHD is a demanding technique with full access to femoral head and acetabular deformities as well as cartilage or labral tears. It can be done safely with a low complication rate. The best results are achieved in young patients without degenerative cartilage and significant labrum changes. Hip degenerative changes contraindicates this procedure. Modification of trochanteric osteotomy does not seem to influence results

Introduction: There are several complications associated with spinal cord injury. The authors propose to evaluate the complications developed during hospitalization of tetraplegic patients treated in our institution.

Materials and Methods: The clinical and imaging records of 20 tetraplegic patients operated between 1995 and 2007 were evaluated (14 men and 6 women; mean age 31.5 years; 16 submitted to surgery using anterior cervical approach, 4 using posterior approach; 8 did steroids protocol during 24h and 12 during 48h; 9 patients were operated less than 48h after trauma and 11 patients after).

Results: Mean hospitalization time was 47.4 days (men 48.9 d, women 23.4 d; anterior approach 50.25 d, posterior approach 39 d; corticosteroids during 24h 34.3 d, 55.3 d in those who did 48h; time until surgery < 48h 43.1 d, > 48h 54.5 d). 100% of patients developed respiratory tract infections.

56.3% of patients developed urinary tract infections (33% in patients doing corticosteroids during 24h, 70% in those who did 48h)

Mean duration of mechanic ventilation was 20.3 days (anterior approach 19.3 d, posterior approach 19.8 d; steroids during 24h 16.7 d, steroids during 48h 21 d; time until surgery < 48h 13.6 d, > 48h 23 d)

In 37.5% of patients a traqueostomy was performed (41.7% in patients submitted to anterior approach, 25% in posterior approach; 16.7% in patients doing steroids during 24h, 50% in those who did 48h; time until surgery < 48h 28.6%, > 48h 50%)

Discussion: This patients are associated with long hospitalization and mechanic ventilation periods. Respiratory tract infection was the most frequent complication. The surgical approach had no influence on mechanic ventilation periods. Those submitted to anterior approach had longer hospitalization periods and higher incidence of traqueostomy. Patients who did corticosteroids during 48h had higher incidence of urinary tract infections and traqueostomy, and longer mechanic ventilation periods. Those operated less than 48h after trauma had shorter hospitalization and mechanic ventilation periods and traqueostomy procedure.

Conclusion: Steroids longer than 24h, anterior cervical approach and time to surgery > 48h tend to be associated with higher complication rates

Introduction – Elbow dislocation in children is a rare lesion and most of the times is associated with a fracture of the medial epicondyle. When there is a fracture of the radial neck it is even more rare and usually represents a major instability with large soft tissue disruption.

Methods – Between 1984 and 2003, 56 patients with unilateral elbow dislocations were identified ranging from 4 to15 years of age. In 8 patients a radial neck fracture was associated and in two there was a radio ulnar translocation . All these patients were treated the same way: closed reduction of the fracture dislocation under general anesthesia, evaluation of the instability and fracture fixation by closed means (Metaizeau technique). No ligamentous reconstruction was performed even in the presence of severe instability after bone reconstruction. A plaster was applied for two weeks followed by active mobilization.

Results – All fractures healed with no complications. All patients except one regained full range of motion. The patient with a loss of extension (20°) complaints of pain on the lateral side during sports activity and has a minor instability test positive for the lateral collateral ligament.

Discussion – This is a rare lesion in children not well documented in the literature. In the adult population there is an emphasis on the necessity of a repair of the soft-tissue structures as an integral part of the surgical strategy for elbow dislocation that require operative treatment (Mckee et al. J Shoulder Elbow Surg. 2003 Jul–Aug;12(4):391–6). In this small series we found no major instability in a long follow-up study even without reconstruction of the soft-tissues.

Conclusion – We concluded that in this particular type of lesion, a close anatomical reduction of the articular surfaces with restoration of the normal relationship around the elbow was fundamental to restore elbow stability with no need for soft-tissue reconstruction

Objectives and Material: The authors have evaluated 78 patients with fractures of the proximal humerus that have been interned in the Orthopedics’ Service at Hospital de Santa Maria since the 1st January of 1995 until the 31st December of 1999 with the objective of evaluating different factors influencing the final results and concluding to the best therapeutic conduct in the different cases. Method: The following parameters have been evaluated: sex, age, accident type (low/high energy), associated injuries, fracture’s classification, type of treatment and results achieved. The Constant score have been used for the functional evaluation. Due to reduced number of patients in each class a non-parametric test has been used – Qui-square test (X2). SPSS program has been used to run the calculations.

Results: It has been verified that sixty four percent of the cases happened due to low energy accidents and the three-part fractures prevailed (46%), followed by four-part fractures (34%). The fracture of the proximal humerus occurred isolated and prevailed in women above 60 years old. Patients’ age was not a factor of bad prognostic. The number of bad results depended on the fracture’s type. Open reduction and internal fixation has been the most frequently used technique in all fracture types and the one with the best results. Open reduction and Kirschner pinning should be used only in very specific cases and with limited functional objectives. Humeral head reconstruction has not been a valid option to four-part fractures treatment, allowing concluding that, in many cases of very fragmented fractures, the option for the humeral head substitution by prosthesis should be better than trying its reconstruction.
