Objective

To the best of the authors’ knowledge, no studies in the literature have compared the clinical outcome of the three most common implants used to treat basicervical fractures of the femoral neck in young adults, i.e. CCS, DHS, and PFN. The present study attempts to fill the void in the literature and reach a conclusion regarding the usefulness of these implants in these fractures.

Methods

This was a prospective interventional study including 90 patients with basicervical fracture of the neck of femur treated randomly with cancellous cannulated lag screws or dynamic hip screw, with a derotation screw or short PFN.

Results

Mean time for fracture union was 14.4, 13.9, and 13.5 weeks and union rate was 93.2%, 100%, and 100% in groups 1, 2, and 3, respectively. The mean Harris Hip Score at the final follow up was similar among all the groups, i.e. 79.4, 82.2, and 81.9 in CCS, DHS, and PFN groups, respectively. The highest proportion of good to excellent results was noted in the DHS group, i.e. 83.3%, whereas it was 73.6% and 80% in the CCS and PFN groups, respectively.

Conclusion

Multiple cancellous screws do not provide a sufficiently stable construct during fracture healing. PFN, although associated with lesser implant failures than CCS, have a higher incidence of technical errors. DHS provides sufficient stability in well-reduced basicervical fractures in young adults; it is associated with highest fracture union rates and best functional outcome out of the three implants at final follow-up.

Heterotopic ossification can be defined as the formation of bone in tissues that have no ossification properties, such as in muscles and connective tissue of a periarticular region, without invasion of the joint capsule. This pathology usually has a benign course, but it can cause a reduction in the range of joint movement and hamper the rehabilitation process. Its etiology is still unknown and it usually is originated from posttraumatic complications, affecting 10–20% of patients with traumatic brain injury. Among its clinical manifestations, it may present pain and limitation of joint movement, heat, edema, and local flushing. In some cases, it can present moderate fever, severe spasticity, and even ankylosis in more advanced stages of the disease. Treatment is based on resection of the ossification, with adjuvant measures such as non-steroidal anti-inflammatory drugs, bisphosphonate, radiotherapy, and physical therapy. None of these methods currently have a precise recommendation regarding dose, quantity, or well-established protocols. Still, the best treatment is prevention. The objective of this report is to describe a case of heterotopic ossification in the hip after traumatic brain injury, presenting the clinical manifestations and discussing the treatment instituted with a long leg plaster cast.

Objective

To assess the clinical and functional results of patients submitted to reverse arthroplasty with a minimum follow-up of one year.

Methods

Twenty-two patients submitted to shoulder reverse arthroplasty by the Surgery and Shoulder Rehabilitation Group were retrospectively evaluated with pre and postoperative imaging analysis, analog pain scale, range of motion, and ASES functional score.

Results

Out of 19 (86.3%) patients with preoperative ASES classified as poor/bad, 11 (57.9%) progress to good/excellent after intervention, showing improvement of function, ranging from a mean preoperative ASES score of 22 (± 18.8) to a postoperative mean of 64.8 (± 27.7) (p = 0.031). Regarding the pain, there was an improvement in analog pain scale, presenting a preoperative mean of 7.64 (1–10) and a postoperative mean of 2.09 (0–7; p < 0.001). Regarding mobility, of 22 patients, 15 (68.2%) had preoperative pseudoparalysis and, of these, ten (66.7%) had an active anterior elevation greater than 90° after reverse arthroplasty. In turn, patients without pseudoparalysis had no significant gain in range of motion (p = 0.002). The authors observed active anterior elevation gain, with a preoperative mean of 76° (0–160°) and a postoperative mean of 111° (0–160°; p = 0.002).

Conclusion

Despite being a relatively new procedure in Brazil, reverse shoulder arthroplasty can be used effectively and safely in patients who were previously without treatment options such as rotator cuff arthropathy and revisions providing pain relief, improvement of function, and mobility of the upper limb.

Objective

To describe the results of the surgical treatment of patients with congenital arthrogryposis with wrist deformity through biplanar carpal wedge osteotomy.

Method

This study analyzed nine patients through a retrospective evaluation with severe deformity in flexion and ulnar deviation of the wrist in the period between January 2004 and December 2009. They were submitted to carpal osteotomy with a biplanar dorsal resection wedge, with a minimum evaluation of 48 months of postoperative evolution. In three patients the osteotomy was bilateral, totalling 12 cuffs analyzed. The indication for the technique described was deformity and stiffness for over six months, without improvement with the conservative treatment.

Results

The mean age of the patients on the day of surgery was five years and eight months. The initial mean wrist mobility was 35°, and the joints presented a mean flexion of 72.5° in a resting position. Osteotomy union occurred in all patients at an average period of 5.7 weeks. The final position of the resting wrist was 12° of flexion and the mean mobility was 26.6°, slightly lower than preoperatively but in a much better position. No serious complications arising from surgery or in the immediate postoperative period were observed.

Conclusions

Carpal osteotomy with biplanar dorsal resection wedge was useful and effective in helping to correct the deformities in flexion and ulnar deviation of the wrist, maintaining a reasonable mobility. It is a preservation surgery, which has low morbidity and avoids the progression of deformity and future degenerative changes.

Objectives

To evaluate the clinical and functional results of patients diagnosed with full-thickness chondral defects on symptomatic knees who underwent a biological repair technique using autologous matrix-induced chondrogenesis.

Methods

Seven patients who underwent surgical treatment due to chondral lesions in the knee by autologous matrix-induced chondrogenesis were evaluated. The Lysholm, Kujala and visual analog scale of pain questionnaires were applied before and 12 months after the surgery. Nuclear magnetic resonance images were evaluated 12 months after surgery according to MOCART (magnetic resonance observation of cartilage repair tissue) cartilage repair tissue score.

Results

Of the seven patients evaluated, three presented defects classified as grade III and four as grade IV according to the International Cartilage Repair Society classification. Chondral defects were located in the medial femoral condyle (n = 2), patella (n = 2), and trochlea (n = 3). The mean age of the patients (six men and one woman) was 37.2 years (24–54 years). The mean chondral defect size was 2.11 cm² (1.0–4.6 cm²). After 12 months, post-operative nuclear magnetic resonance showed resurfacing of the lesion site with scar tissue less thick than normal cartilage in all patients. The mean MOCART score was 66.42 points. A significant decrease in pain and an improvement in the Lysholm and Kujala scores were observed.

Conclusion

The use of the collagen I/III porcine membrane was favorable for the treatment of chondral and osteochondral lesions of the knee when assessing the results using the VAS, Lysholm, and Kujala scores 1 year after surgery, as well as when assessing the magnetic resonance image of the lesion 6 months after surgery.

Objective

Avascular necrosis of the hip is a common debilitating disease during the fourth and fifth decades of life. This study attempted to evaluate quality of life in patients with avascular necrosis of the hip joint before and after surgery.

Methods

In this study, 40 patients with avascular necrosis of the hip who underwent total hip arthroplasty, bipolar surgery, or cord compression were examined during 2006–2013. Harris Hip Score was used to assess the hip joint function and quality of life before and after surgery. The mean scores and standard deviation were used to describe data for quantitative variables, while frequency percentage was used to describe qualitative variables. Data were analyzed through SPSS v.19 and paired t-test. p < 0.05 was considered significant.

Results

This study involved 40 subjects with a mean age of 32 ± 7.38 years, ranging from 21 to 45 years old. The mean Harris Hip Score for patients before and after surgery were 20.36 and 96.15, respectively, showing a statistically significant difference (p < 0.001). The average patient activity scores before and after surgery (8.9 and 44.2, respectively), non-deformity (1.6 and 3.9), and movement (3.6 and 4.9) indicated significant differences (p < 0.001). Furthermore, 80% of patients felt no hip joint pain six months after surgery, while 92.5% patients did not use any assistive device to walk.

Conclusions

The results of this study demonstrated that surgery substantially contributed to relieving pain and improving hip function in patients with osteonecrosis of the hip joint in the short term.

Objective

This trial investigated postoperative analgesia in arthroscopic rotator cuff repair surgery patients under general anesthesia, associated with ultrasound-guided peri-plexus interscalene brachial plexus block (US-IBPB), and compared single injection to elastomeric pump continuous infusion of local anesthetics. Complications associated to both techniques are described.

Methods

In this prospective, quasi-randomized controlled clinical trial, 68 adults scheduled for elective arthroscopic rotator cuff repair were assigned to receive Group 1 (G1 = 41) US-IBPB with a 20 mL injection of 0.5% peri-plexus ropivacaine, introduction of catheter, injection of 20 mL of 0.5% ropivacaine through continuous catheter infusion of local anesthetic by elastomeric pump (ropivacaine 0.2%, infusion of 5 mL/h). In Group 2 (G2 = 27), US-IBPB, with a single peri-plexus injection of 40 mL ropivacaine 0.5%. In both groups oral analgesics were prescribed, paracetamol 500 mg associated to codeine 30 mg for patients with VAS between 3 and 5, and also oxycodone 20 mg for VAS ≥ 6. The anesthesiology team was available through contact telephones and the patients received a table to complete in order to report pain intensity according to VAS, use of oral medication, and complications related to the catheter and pump, until the third postoperative day.

Results

The intensity of pain was higher on second day after surgery than on days 1 and 3, in both groups confirmed by the ANOVA test (p = 0.00006) Among the groups, G1 patients had lower pain intensity than G2, (p = 0.000197). G2 patients presented greater pain intensity during all periods studied (days 1, 2, and 3) than G1 patients. Postoperatively, G2 patients had higher consumption of rescue analgesics, nausea, and vomiting (40.74%) vs. G1 (5%) and dizziness (25.92%). No patient with catheter and elastomeric pump (G1) had complications regarding its insertion and maintenance during postoperative period.

Conclusion

The quality of analgesia for arthroscopic rotator cuff repair with peri-plexus US-IBPB and continuous infusion with elastomeric pump presented superior postoperative analgesia quality to single puncture IBPB on postoperative days 2 and 3, with lower consumption of rescue opioids in this period.

Objective

To evaluate the clinical and radiologic results of proximal femoral varus derotational and shortening osteotomy (OVRF) (Port., doesn’t match name) with the use of a locked plate in patients with cerebral palsy, classified by the gross motor functional classification system as class IV or V.

Methods

A retrospective study of 42 patients (61 hips) with cerebral palsy, gross motor functional classification system class IV or V, submitted to OVRF. The minimal follow up was 24 months. This study evaluated clinical (age at surgery, gender, Gross Motor Functional Classification System class, anatomical cerebral palsy classification, and motor pattern), pre- and post-operative radiological (neck shaft angle, acetabular index, Reimers migration index and time until bone healing) characteristics, as well as post-operative complications.

Results

Mean pre-operative cervicodiaphyseal angle, acetabular index, and Reimers migration index were respectively 121.6°, 22.7°, and 65.4% in uncomplicated cases, and 154.7°, 20.4°, and 81.1% in complicated ones. All parameters were statistically significant difference between pre- and postoperative values (p < 0.05). The patients with postoperative complications had a greater cervicodiaphyseal angle and Reimers migration index (p < 0.0001). There were no differences in clinical characteristics, time of immobilization, or bone healing. Fourteen patients had postoperative complications (33.3%), but only six required surgical treatment.

Conclusion

The locked plate is a safe resource, with low complication rates and reproducible technique for OVRF in the cerebral palsy population classified as gross motor functional classification system IV and V. Greater cervicodiaphyseal angles and Reimers migration index are associated with greater chances of postoperative complications, as well as gross motor functional classification system V classification.

Objective

The objective of this study was to evaluate the relationship between the neutrophil/lymphocyte ratio and the presence of signs of arthrosis in both hips in patients followed at this medical center.

Methods

This was a cross-sectional, retrospective study through the analysis of medical records and database review of patients over 18 years of age with hip arthrosis, followed at the outpatient clinic of this hospital.

Results

Regarding the analysis of the Mann–Whitney test to correlate the neutrophil/lymphocyte ratio and laterality, a bi-lateral test result of p = 0.036 was obtained, thus demonstrating a significant difference between the observed groups. When we analyzed the absolute values of neutrophils and lymphocytes, the authors obtained results of p = 0.14 and p = 0.24. Therefore, it was not possible to observe statistically significant differences between the absolute values in the two groups.

Conclusion

Considering the interactions between the inflammatory mechanisms in osteoarthritis and the fact that the interaction between neutrophils and lymphocytes has differences in relation to the laterality of the coxarthrosis, it is hypothesized that the inflammatory etiology of unilateral and bilateral osteoarthritis could have different dynamics. However, more in-depth studies with flow cytometry are needed to assess the possible impact of these differences in the inflammatory mechanisms observed in this study.

Thumb injuries are not as common as those occurring in the fingers. The authors present the case of a patient who had an isolated avulsion of the extensor pollicis brevis that resulted in metacarpophalangeal joint instability, with intact radial and ulnar collateral ligament.
