Objective

The aim of this study was to evaluate the functional outcome of surgically treated acetabular fractures.

Methods

A prospective longitudinal study was undertaken in this hospital during the period from December 2010 to December 2014. A total number of 46 patients with the diagnosis of acetabular fracture were included in the study. The main cause of the acetabular injury was a road traffic accident. All the patients were treated surgically with plates and screws. Outcome was assessed radiologically and functionally, employing the Harris Hip Score. The mean follow-up period of the patients in the postoperative period was 30 months (24–36 months).

Results

The results were excellent in 60.86%, good in 21.73%, fair in 8.69%, and poor in 8.69%. Post-operative complications of acetabular fracture such as heterotopic ossification were found in 2.17%, osteoarthritis in 6.52%, skin infections in 4.34%, nerve lesions in 2.17%, and vascular necrosis in 4.34% of patients. More than 80% of patients were satisfied with the results of acetabular surgeries.

Conclusion

These results show that internal fixation of acetabular fractures leads to a good outcome in the majority of patients.

The authors report a rare case of osteochondritis dissecans of the trochlea. The treatment of these lesions, in which the osteochondral fragment is not viable, is difficult and often limited in Brazil. A clinical case is presented with functional and radiological outcomes after treatment with microfracture technique, bone graft, and collagen membrane coverage.

Objectives

To determine the role of immunohistochemistry in identifying the primary site of tumors, and in establishing which bones are most frequently involved, their relationship with the primary tumor site, and the rate of pathologic bone fracture as the first symptom of a malignant tumor.

Methods

A retrospective analysis of all medical records on bone metastases the cases treated between January 2006 and December 2011 at the Department of Orthopedics and Traumatology was performed.

Results

Immunohistochemistry correctly determined the primary tumor site in 61.2% of cases analyzed. Regarding the metastatic site, the most affected bone was the femur, accounting for 49.6% of the sample. Bone metastasis was the first symptom of the tumor in only 20.2% of patients, and of these, 95% were admitted for pathologic bone fracture.

Conclusion

The study showed that the primary sites and their incidence rate are consistent with the literature reviewed. It was noted that in this sample, most patients did not present with pathologic bone fracture as the first clinical symptom of neoplastic disease. However, analysis of those patients that had a metastasis as the first clinical symptom revealed that it manifested itself as a pathologic fracture in almost all cases. The immunohistochemical study was consistent with the primary tumor site in most cases, indicating the value of the method in the detection of the primary site.

Fournier's gangrene is a rare, high-mortality infection that affects the subcutaneous tissue with rapidly progressive necrosis. The objective is to report a case of Fournier's gangrene involving the region of the shoulder girdle after closed fracture of the clavicle, and to discuss this unusual evolution. The patient underwent a series of surgical procedures and was followed up on an outpatient basis for 12 months, at which point she was discharged. Fournier's gangrene is an aggressive lesion and requires early diagnosis (clinical-laboratory correlation) with the appropriate adequate surgical approach and clinical stabilization.

Objective

Evaluate and compare the results of single-row (SR) vs. double-row (DR) arthroscopic rotator cuff repair.

Methods

From December 2009 to May 2013, 115 arthroscopic rotator cuff repairs were performed using suture anchors. After applying the exclusion criteria, there were 75 patients (79 shoulders) to be evaluated, retrospectively, of whom 53 (56 shoulders) attended re-evaluation. The patients were divided into two groups: SR with 29 shoulders, and DR) with 27 shoulders. The scoring systems for clinical evaluation were those of the University of California at Los Angeles (UCLA) and the American Shoulder and Elbow Surgeons (ASES).

Results

The mean follow-up period in the SR group was 37.8 months vs. 41.0 months in the DR group. The average UCLA score was 30.8 in the SR group vs. 32.6 in the DR group. This difference was not statistically significant (p > 0.05). The averages measured by the ASES score also showed no significant difference – 82.3 and 88.8 in the SR and DR groups, respectively.

Conclusion

No statistically significant difference was found between SR and DR arthroscopic rotator cuff repair performed by a single surgeon in the comparative analysis of UCLA and ASES scores.

Objective

To evaluate the inclination and the length of the femoral tunnel in patients submitted to anterior cruciate ligament reconstruction (ACL) surgery by transtibial and anatomical techniques.

Methods

This is an analytical observational study in patients with ACL injury that underwent arthroscopic reconstruction through transtibial and anatomical surgical techniques. In the immediate postoperative period, computed tomography (CT) and anteroposterior (AP) view digital radiographs (X-rays) were performed to evaluate the inclination and length of the femoral tunnel.

Results

Forty-two patients were analyzed: 27 underwent anatomical reconstruction and 15, transtibial reconstruction. The inclination angle and tunnel length by the transtibial technique are always greater than by the anatomical technique. The mean inclination angles were 59.75° (53.9–66.1°) in the X-rays and 54.17° (43.5–62.3°) in CT for the transtibial technique, and 42.91° (29.3–57.4°) in the X-rays and 39.10° (23.8–50.6°) in CT for the anatomical technique. Regarding the length of the femoral tunnel, the transtibial technique promotes longer tunnels: mean 55.7 mm (40.0–70.2 mm) in the transtibial and 35.5 mm (24.5–47 mm) in the anatomical technique. No statistically significant correlation was observed between the length and the inclination of the tunnel, regardless of the technique used. Thus, these variables can be considered as independent.

Conclusion

The anatomical reconstruction technique presented shorter femoral tunnels and lower angle of inclination than the transtibial technique. The CT showed smaller inclination angle than the X-rays, regardless of the surgical technique.

Objectives

To determine the prevalence of high patella in adult patients with knee pain, and to correlate patellar height with symptoms of patellar instability, episode of patellofemoral dislocation and anterior pain in the knee; and also verify the concordance correlation between the Insall-Salvati and Caton-Deschamps indices.

Method

Cross-sectional study analyzing the medical records of patients with knee pain, using lateral view knee radiographs with 30° degrees of flexion and computed tomography. The values of the Insall-Salvati index and the Caton-Deschamps index were used to determine the patellar height.

Results

A total of 756 records were analyzed, resulting in 140 knees studied, 39% men and 61% women. Both indices produced statistically significant associations for the occurrence of high patella and signs of instability and episodes of dislocation, but there was no significant association for anterior knee pain. The Kappa index obtained when analyzing the concordance correlation between the Insall-Salvati index and Caton-Deschamps index points to a regular association between them.

Conclusion

Patients with high patella present a higher prevalence of instability. Having a high patella has no significant relationship with the presence of anterior knee pain. The Insall-Salvati and Caton-Deschamps indices demonstrate a regular agreement on the presentation of patellar heights results.

Objective

To evaluate and compare the clinical and radiological outcomes of patients with stable intertrochanteric fractures treated with proximal femoral nail vs. dynamic hip screw.

Methods

Sixty patients with stable intertrochanteric fractures, aged over 18 years, were randomly divided into the proximal femoral nail and dynamic hip screw groups. Dynamic hip screw with a three-hole side-plate and an anti-rotation screw were used, as well as a modified ultra-short proximal femoral nail for the smaller Asian population. The intra-operative, early and late complications were recorded, and the functional outcome of each group was assessed using the Harris Hip Score.

Results

In the dynamic hip screw group, the one-month mean Harris Hip Score was slightly lower than that of the proximal femoral nail group. However, at the three- and six-month monthly follow-ups, the dynamic hip screw group presented higher mean scores than the proximal femoral nail group; at the one-year follow-up, both the groups attained similar scores.

Conclusion

Proximal femoral nail provides a significantly shorter surgery with a smaller incision that leads to less wound-related complications. However, the incidence of technical errors was significantly higher in proximal femoral nail when compared with dynamic hip screw as it is a technically more demanding surgery that leads to more implant failures and the consequent re-operations.

Musculoskeletal injuries such as dislocation of the shoulder and hip joints and fractures of the femoral neck are known complications of seizures. Bilateral central subluxation of the hip joint with associated bilateral quadrilateral plate fracture is a rare entity and is prone to delayed diagnosis, even more so in patients who experience post-seizure disorientation. The authors report the case of a 74-year-old male patient with bilateral central subluxation of the hip joint with associated bilateral quadrilateral plate fracture due to seizure activity. Bilateral open reconstruction and fixation of the quadrilateral plate with a 3.5-mm pre-bent reconstruction plate reinforced with 3.5-mm pelvic brim reconstruction plate was performed. In conclusion, this case is an example of rare bilateral quadrilateral plate fracture caused due to seizure activity, a fracture for which a high level of suspicion should be kept in mind while evaluating the patient post-seizure episode.

Objective

This study aims at analyzing retrospectively the clinical-functional and radiographic results of surgical treatment of the terrible elbow triad, with at least 12 months of postoperative follow-up evaluating elbow function.

Methods

A group of patients for retrospective analysis from 2004 to 2015 was defined, in which 12 patients were studied. They underwent surgery due to fracture of the radial head, coronoid fracture, and elbow dislocation; they were evaluated by the Disabilities of the Arm, Shoulder and Hand (DASH) score, the degree of patient satisfaction, the degree of trauma energy, radiographic images, range of motion, and complications.

Results

There was a higher incidence of Regan and Morrey type II coronoid process fractures; in relation to the injuries, nine patients had deinsertion of the brachialis. Half of the patients suffered a fall from their own height as the mechanism of trauma. The extent of elbow flexion and extension averaged 126.6 and 24.1 degrees, respectively; the averages for pronation and supination were 64.1 and 62.0 degrees, respectively. All patients presented muscle strength of grade IV or V. The mean DASH score was 14.3, the mean pain score was 2.5, and a majority of the patients were satisfied with the treatment.

Conclusion

Despite the total loss of range of motion of the elbow, especially in extension, the treatment was satisfactory for most patients.
