Evaluation of the ischiofemoral space: a case-control study.

OBJECTIVE: To determine the size of the ischiofemoral space (IFS) and quadratus femoris space (QFS) in patients with and without ischiofemoral impingement (IFI). MATERIALS AND METHODS: Case-control study including consecutive patients submitted to magnetic resonance imaging (MRI) of the hip joint during a three-month period. Patients with deep gluteal pain who tested positive for IFI on at least one clinical test and showed signal changes in the quadratus femoris muscle on MRI were categorized as having a confirmed diagnosis of IFI. RESULTS: Final sample comprised 50 patients submitted to unilateral MRI of the hip joint. The mean age was 47.3 ± 14.0 years (range, 22-76 years), and 33 (66%) of the patients were women. A diagnosis of IFI was made in 6 patients (12%), all of whom were female. On average, IFS and QFS were significantly smaller in IFI group than in control group (11.1 ± 2.7 mm versus 27.5 ± 6.5 mm and 5.3 ± 1.8 mm versus 18.8 ± 4.8 mm, respectively; p < 0.001 for both). CONCLUSION: Results of specific clinical tests and MRI findings indicate that the IFS and QFS are significantly reduced in patients with IFI.

Reliability of the Arthroscopic Classifications of Hip Chondral Lesions.

Objective To evaluate the inter- and intraobserver reliability of the Outerbridge, Beck, and Haddad classifications for acetabular joint cartilage lesions through the arthroscopic procedure. Methods A total of 60 hip arthroscopy videos were evaluated twice by 4 surgeons at 2 different times to assess the inter- and intraobserver reproducibility of the classifications, and the data was analyzed by means of the weighted Cohen Kappa index. Results The mean weighted Kappa values in the interobserver assessment of the Outerbridge, Beck, and Haddad classifications were, respectively, 0.72, 0.78, and 0.68. The three classifications were considered as presenting good interobserver agreement. Regarding the intraobserver assessment of the Outerbridge, Beck, and Haddad classifications, the weighted Kappa values were, respectively, 0.9, 0.9, and 0.93. The three classifications were considered as presenting excellent intraobserver agreement. Conclusion In the present series, the Outerbridge, Beck, and Haddad classifications presented good interobserver reproducibility and excellent intraobserver reproducibility when evaluating acetabular chondral lesions by the arthroscopic approach.

Recovery of the Hip Rotation Center with Tantalum in Revision Arthroplasty.

Objective The objective of the present study is to evaluate the restoration capacity of the hip anatomic rotation center with the use of acetabular tantalum cups, associated or not with addition wedges. Methods Retrospective analysis of patients undergoing hip arthroplasty revision using tantalum between June 2013 and April 2017. The abduction angle of the acetabular component and the horizontal and vertical distances of the component to the center of anatomical rotation of the hip were evaluated. The measurements were made through baseline radiographs performed in the preoperative period and at the last follow-up visit. Results A sample of 21 patients was obtained, 11 (52%) men and 10 (48%) women, with a mean age of 62 ± 13 years old. The mean abduction angle of the acetabular cup decreased from 48.76° ± 13.88 ° in the preoperative period to 38.52° ± 10.08 ° in the postoperative period, and this difference was statistically significant ( p = 0.001). The distances from the center of rotation of the prosthesis relative to the center of anatomical rotation of the hip were also lower after revision surgery with tantalum. The mean horizontal distance of 12.74 ± 10.59 mm was reduced to 7.11 ± 4.84 mm, and the mean vertical distance was reduced from 14.79 ± 10.05 mm to 4.89 ± 6.21 mm, and these reductions were statistically significant ( p < 0.001). Conclusion Hip arthroplasty revision with tantalum cups, associated or not with addition wedges, significantly recovered the anatomical rotation center of the hip.

Piriformis Pyomyositis in a Patient with Kikuchi-Fujimoto Disease - A Case Report and Literature Review.

Primary pyomyositis is a deep bacterial infection of the skeletal muscle. If left undiagnosed and untreated, the infection spreads, leading to sepsis, septic shock, and even death. The authors report a 23-year-old female presenting with piriformis pyomyositis during a treatment for Kikuchi-Fujimoto disease. Pyomyositis is a rare but potentially severe infection, which can lead to septic shock. The present case shows the need for a high degree of clinical suspicion for patients with compromised immune systems to begin treatment at an early stage. The literature demonstrates that outcomes of the treatment of piriformis pyomyositis are good.

Resumo A piomiosite primária é uma infecção bacteriana profunda do músculo esquelético. Quando não diagnosticada ou tratada, a infecção pode evoluir para sepse, choque séptico e até morte. Os autores relatam o caso de uma paciente do sexo feminino, 23 anos, apresentando piomiosite do músculo piriforme durante o tratamento da doença de Kikuchi-Fujimoto. A piomiosite é uma infecção rara, mas potencialmente grave, que pode levar ao choque séptico. Esse caso mostra a necessidade em se elevar o grau de suspeição clínica em pacientes com comprometimento do sistema imunológico, para que o tratamento seja iniciado em estágio precoce. A literatura mostra que os resultados do tratamento da piomiosite do piriforme são bons.

Clinical outcomes of arthroscopic repair of acetabular labral tears.

PURPOSE: To evaluate the primary clinical outcomes of arthroscopic labral repair. METHODS: All patients who underwent arthroscopic repair of the acetabular labrum performed by a senior surgeon between October 2010 and December 2013 were invited to participate in this prospective study. Patients included were those who had a preoperative diagnosis of labral tears, a lateral centre edge greater than 25° and a labral tear believed to be suturable during the intraoperative evaluation. Patients with Tönnis grade 2 or grade 3 hip osteoarthritis and those who had undergone a previous hip surgery were excluded. All patients were evaluated using the modified Harris Hip Score (mHHS) during the final appointment before surgery, 4 months after surgery and at the final evaluation. Interviews were conducted by the senior surgeon. RESULTS: Eighty-four patients (90 hips) underwent arthroscopic repair. The mean age was 44.2 years and the mean follow-up period was 43.0 months (minimum of 25 months and maximum of 59 months). The mean mHHS was 80.4 preoperatively, 95.0 at 4 months postoperatively and 96.6 at final evaluation. A statistically significant difference existed among these scores (p<0.001). CONCLUSION: Arthroscopic labral repair was associated with a clinically significant improvement in mHHS after short-term (4 months) and medium-term (43 months) follow-up. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Efficacy evaluation of a protocol for safe hip surgery (total hip arthroplasty).

OBJECTIVE: To propose a multidisciplinary protocol to standardize the care of patients undergoing total hip arthroplasty (THA) and evaluate it effectiveness after implementation. METHODS: Retrospective evaluation of 95 consecutive patients undergoing THA divided into two groups, one group of 47 patients operated before the protocol implementation and 48 after. RESULTS: Assessing the re-admission rate, among 47 patients evaluated prior to implementation of the protocol, seven (14.9%) were re-admitted, and when observing the 48 patients evaluated after implementation, one (2.1%) was re-admitted, showing statistical significance (p < 0.05). The chance of re-admission before the protocol was eight times the chance of hospitalization after implementation (95% CI: 1.01 to 377.7). By comparing the clinical complications among the groups, it was observed that there was a lower rate of complications following implementation of the protocol (p = 0.006). CONCLUSION: The introduction of a multidisciplinary protocol to standardize the management of patients undergoing THA decreased the rates of rehospitalization and clinical complications after the procedure.

OBJETIVO: Propor um protocolo multidisciplinar para padronização do cuidado dos pacientes que serão submetidos a artroplastia total do quadril (ATQ) e avaliar sua eficácia após a implantação. MÉTODOS: Avaliação retrospectiva dos resultados de 95 pacientes consecutivos submetidos a ATQ divididos em dois grupos, um com 47 operados antes da implantação do protocolo e 48 após. RESULTADOS: Na avaliação da taxa de reinternação, tem-se que entre os 47 pacientes avaliados antes da implantação do protocolo, sete (14,9%) foram reinternados e dos 48 avaliados depois da implantação, um (2,1%) foi reinternado, mostrou-se significância estatística (p < 0,05). A chance de reinternação antes da implantação foi oito vezes maior do que a chance de internação após a implantação (IC 95%: 1,01 a 377,7). Ao comparar as complicações clínicas entre os grupos observou-se que houve menor taxa de complicações após a implantação do protocolo (p = 0,006). CONCLUSÃO: A introdução de um protocolo multidisciplinar para padronização do manejo do paciente submetido a ATQ diminuiu as taxas de reinternação e de complicações clínicas após o procedimento.

Diffuse pigmented villonodular synovitis in knee joint: diagnosis and treatment.

Pigmented villonodular synovitis is a rare proliferative condition of the synovium. Although the condition can present in any joint, the knee is the most commonly affected site. Despite being a benign condition, pigmented villonodular synovitis is often aggressive, with marked extra-articular extension in some cases. Monoarticular involvement occurs in two forms: localized and diffuse. The latter is more common, with a high recurrence rate. There is no standard method of management of this lesion. Open surgery is a classical and effective method for treatment. Arthroscopic synovectomy, however, has gained popularity, and has several advantages over the open technique particularly in exclusively articular cases. The combined approach is suggested in cases with extra-articular involvement. Synovectomy through any approach may prevent secondary osteoarthritis and subsequent joint arthroplasty. Internal irradiation or external beam radiation as an adjuvant treatment to surgical synovectomy appears to decrease the rate of local recurrence in diffuse cases. The authors observed a great heterogeneity in reporting of functional results, and specific conclusions should not be drawn. Each patient should be managed in accordance with his/her particular condition.

A sinovite vilonodular pigmentada é uma rara condição proliferativa da membrana sinovial. Apesar de a doença poder estar presente em qualquer articulação, o joelho é o local mais frequentemente afetado. Ainda que doença benigna, geralmente tem comportamento agressivo, pode ter extensão extra-articular em alguns casos. O acometimento monoarticular ocorre em duas formas: localizada ou difusa. A forma difusa é mais comum e tem alta taxa de recorrência. Não há método padronizado para o manejo dessa lesão. O tratamento cirúrgico aberto é o método clássico e efetivo. A sinovectomia artroscópica, entretanto, tem ganhado popularidade e tem diversas vantagens sobre a técnica aberta, principalmente em casos exclusivamente articulares. A abordagem combinada é sugerida em casos com envolvimento extra-articular. A sinovectomia pode prevenir a osteoartrose secundária e o subsequente tratamento reconstrutivo. A radioterapia usada como tratamento adjuvante à sinovectomia parece diminuir a taxa de recorrência local na forma difusa da doença. Os autores encontraram grande heterogeneidade na forma como os resultados funcionais foram reportados e não se deve chegar a conclusões específicas. Cada paciente deve ser manejado de acordo com suas particularidades.

A New Technique for Surgical Treatment of Proximal Hamstring Tendinopathy in a Triathlon Athlete.

INTRODUCTION: Proximal hamstring tendinopathy (PHT) is the result of chronic overload caused by repetitive eccentric contraction. Surgical treatment becomes an option for patients with chronic symptoms that do not respond to conservative treatment. CASE REPORT: This report describes a case of a 48-year-old man, an amateur triathlete, with deep gluteal pain in the left hip for 12 months, leading to a decline in sports performance. Magnetic resonance imaging revealed abnormalities that suggested a PHT. Surgery was indicated following the failure of conservative treatments. Debridement of the conjoint tendon and its reinsertion associated with semimembranosus tenotomy showed good results and is thus an option for the treatment of this pathology after 12 months of follow-up. CONCLUSION: This article provides surgeons with a new surgical option for this debilitating condition with clinical and functional improvement after 12 months of follow-up.
