    Looking beyond Piriformis Syndrome: Is It Really the Piriformis?

    Shivam Sharma, B.Ph.T , Harmanpreet Kaur, Nishank Verma, M.Ph.T, Bibek Adhya, M.Ph.T

    Hip Pelvis 2023; 35(1): 1-5
    Abstract
    Piriformis syndrome is a common differential diagnosis related to sciatica. The following review provides a concise synopsis of the diagnosis, management, history, and alternatives to diagnosis of piriformis syndrome. A search of the literature for research articles related to piriformis syndrome and associated differential diagnosis of sciatica was conducted. A thorough review of the included articles found that the condition known as piriformis syndrome is over-diagnosed and that potential anatomic and biomechanical variations originating in the pelvic region might be related to the complaint of sciatica. The criteria for diagnosis are based on findings from both physical examination and radio imaging. Piriformis syndrome resembles a variety of clinical conditions; therefore, conduct of future studies should include development of a validated method for evaluation as well as clinical criteria for diagnosis of piriformis syndrome.

    Pathophysiology and Treatment of Gout Arthritis; including Gout Arthritis of Hip Joint: A Literature Review

    Yonghan Cha, MD , Jongwon Lee, MD , Wonsik Choy, MD , Jae Sun Lee, PhD*,† , Hyun Hee Lee, MD , Dong-Sik Chae, MD

    Hip Pelvis 2024; 36(1): 1-11
    Abstract
    Gout is triggered by the accumulation of uric acid in the body, leading to hyperuricemia. Genetic, metabolic, and environmental factors can influence this condition. Excessive uric acid buildup results in the formation of monosodium urate (MSU) crystals, which precipitate in specific areas of the body, including the joints, where they can cause symptoms of gout. While the acute and chronic symptoms of gout have been well-documented, diagnosis of gout affecting the hip joint poses significant challenges. The global incidence of gout, the most prevalent form of inflammatory arthritis, is on the rise. Evaluation of the clinical signs, laboratory results, and imaging results is generally required for diagnosis of gout in cases where MSU crystals have not been detected. Hyperuricemia is considered a primary cause of arthritis symptoms, and comprehensive guidelines for treatment are available. Therefore, the choice of medication is straightforward, and moderate effectiveness of treatment has been demonstrated. Gout is a chronic disease, requiring lifelong uric acid-lowering medications, thus application of a treatment strategy based on the target blood uric acid concentration is necessary. Consequently, cases of gout will likely be observed more frequently by hip surgeons in clinical scenarios in the future. The objective of this review is to provide an overview of the pathophysiology of gout and subsequently examine recent advances in diagnostic methods and therapeutic agents based on an understanding of its underlying mechanisms. In addition, literature on gout-related issues affecting the hip joint, providing a useful reference for hip surgeons is examined.

    Jad Mansour, MD , Ziad Zalaquett, MD* , Jean Tarchichi, MD* , Michel Estephan, MD , Joeffroy Otayek, MD , Mohammad Daher, MD

    Hip Pelvis 2025; 37(1): 17-25
    Abstract
    Trochanteric fractures of the femur pose an increasing burden for elderly people. The standard treatment for these types of fractures includes cephalomedullary nailing, which can be augmented with cement. Although many studies have reported on the stability of this augmented construct, few studies have examined its clinical benefit and safety. Therefore, the objective of this meta-analysis is to examine the perioperative complications and postoperative mortality associated with cement-augmented nails in the management of intertrochanteric and pertrochanteric fractures of the hip. A search of PubMed, Cochrane, and Google Scholar (pages 1-20) until January 2024 was conducted. Analysis of the outcomes included perioperative complications and postoperative mortality. Seven studies were included in this meta-analysis. Fewer perioperative complications were observed when using a cemented femoral nail (P=0.002), although there was no difference in postoperative mortality (P=0.30). This meta-analysis is the first to assess the safety of a cement-augmented femoral nail in management of intertrochanteric and pertrochanteric fractures. The results showed a reduced rate of perioperative complications, which may be attributed to a more a solid construct, which reduced the duration of postoperative immobilization as well as use of a proper augmentation technique, resulting in a reduced rate of cement-associated complications.

    Sharath K. Ramanath, MS, DNB , Tejas Tribhuvan, MS* , Uday Chandran, MS , Rahul Hemant Shah, MS* , Ajay Kaushik, MS* , Sandesh Patil, MS*

    Hip Pelvis 2024; 36(1): 37-46
    Abstract
    Purpose: The prognosis of total hip replacement (THR) after open reduction and internal fixation (ORIF) versus THR following non-operative treatment of acetabular fractures is unclear. Few studies have been conducted in this regard. Therefore, the purpose of the current study was to perform an assessment and compare the functional outcomes for study subjects in the ORIF and non-ORIF groups during the follow-up period compared to baseline.
    Materials and Methods: This longitudinal comparative study, which included 40 patients who underwent THR for either posttraumatic arthritis after fixation of an acetabular fracture or arthritis following conservative management of a fracture, was conducted for 60 months. Twenty-four patients had undergone ORIF, and 16 patients had undergone nonoperative/conservative management for acetabular fractures. Following THR, the patients were followed up for monitoring of functional outcomes for the Harris hip score (HHS) and comparison between the ORIF and non-ORIF groups was performed.
    Results: The HHS showed significant improvement in both ORIF and non-ORIF groups. At the end of the mean follow-up period, no significant variation in scores was observed between the groups, i.e., ORIF group (91.61±6.64) compared to non-ORIF group (85.74±11.56). A significantly higher number of re-interventions were required for medial wall fractures and combined fractures compared to posterior fractures (P<0.05).
    Conclusion: THR resulted in improved functional outcome during follow-up in both the groups; however, the ORIF group was observed to have better functional outcome. Re-intervention was not required for any of the posterior fractures at the end of the mean follow-up period.

    Management of Severe Bone Defects in Femoral Revision following Total Hip Arthroplasty

    Yicheng Li, PhD , Li Cao, MD

    Hip Pelvis 2024; 36(2): 101-107
    Abstract
    Treatment of femoral bone defects continues to be a challenge in revision total hip arthroplasty (THA); therefore, meticulous preoperative evaluation of patients and surgical planning are required. This review provides a concise synopsis of the etiology, classification, treatment strategy, and prosthesis selection in relation to femoral bone loss in revision THA. A search of literature was conducted for identification of research articles related to classification of bone loss, management of femoral revision, and comparison of different types of stems. Findings of a thorough review of the included articles were as follows: (1) the Paprosky classification system is used most often when defining femoral bone loss, (2) a primary-length fully coated monoblock femoral component is recommended for treatment of types I or II bone defects, (3) use of an extensively porouscoated stem and a modular fluted tapered stem is recommended for management of types III or IV bone defects, and (4) use of an impaction grafting technique is another option for improvement of bone stock, and allograft prosthesis composite and proximal femoral replacement can be applied by experienced surgeons, in selected cases, as a final salvage solution. Stems with a tapered design are gradually replacing components with a cylindrical design as the first choice for femoral revision; however, further confirmation regarding the advantages and disadvantages of modular and nonmodular stems will be required through conduct of higher-level comparative studies.

    Kyung-Jae Lee, MD, Sang-Hyun Um, MD , Young-Hun Kim, MD

    Hip Pelvis 2020; 32(3): 125-131
    Abstract
    As the proportion of elderly individuals within the population grows, the incidence of hip fractures increases. Traditionally, orthopedic surgeons used to focus on surgical treatment of hip fractures; however, the field’s appreciation for the importance of postoperative rehabilitation has been increasing recently. Many studies have shown that proper rehabilitation after hip fracture surgery can shorten hospital stays and improve clinical outcomes. However, such studies use different methods and published rehabilitation protocols address varying aspects that do not always overlap. Here, we review and summarize the latest guidelines and studies on postoperative rehabilitation of elderly patients with hip fractures.

    Abstract
    There is still controversy regarding clinical outcomes following primary hip arthroplasty after solid organ transplantation (SOT). The aim of this study was to determine whether clinical outcomes after hip arthroplasty differ between previous SOT recipients and control subjects with no history of undergoing SOT. We conducted a systematic search of MEDLINE, Embase, and the Cochrane Library for studies comparing the clinical outcomes after hip arthroplasty following SOT published up to January 5, 2022. A comparison of medical and surgery-related complications, as well as the readmission rate and 90-day mortality rate between previous SOT recipients and control subjects was performed. Subgroup analyses of the SOT types, liver transplantation (LT) and kidney transplantation (KT), were also performed. Ten studies that included 3,631,861 cases of primary hip arthroplasty were included; among these, 14,996 patients had previously undergone SOT and 3,616,865 patients had not. Significantly higher incidences of cardiac complications, pneumonia, and acute kidney injury were observed in the SOT group compared with the control group. Regarding surgical complications, a higher transfusion rate was observed in the SOT group. The readmission rate and 90-day mortality rate were also significantly higher in the SOT group. A significantly higher incidence of deep vein thrombosis was observed in the KT subgroup compared with the control group. A higher risk of medical and surgical complications, as well as higher readmission and mortality rates after hip arthroplasty was observed for previous SOT recipients compared to patients with no history of SOT.

    Direct Anterior Approach in Total Hip Arthroplasty: A Single Center Experience

    Rajesh Malhotra, MS , Sahil Batra, MS , Vikrant Manhas, MS, DNB , Jaiben George, MS , Anitta Biju, GNM , Deepak Gautam, MS*

    Hip Pelvis 2024; 36(3): 196-203
    Abstract
    Purpose: The direct anterior approach (DAA) for conducting total hip arthroplasty (THA) is gaining popularity worldwide. However, careful selection of patients and surgeon experience are important. Although promising outcomes have been reported in international studies, research on DAA in Southern and Southeast Asia has been limited.
    Materials and Methods: This prospective study included 157 patients who underwent THA using the DAA between January 2019 and June 2022. The patients were divided into three groups for the comparison. Data on preoperative, intraoperative, and postoperative variables were acquired. Improvement of the surgeon’s performance to use of a DAA approach was examined using the CUSUM (cumulative summation method).
    Results: The mean age of the patients was 43.9 years. Differences in intraoperative variables and complications were observed among the three groups, and improved outcomes were reported in later cases. Functional outcomes showed significant improvement, and no differences were observed between groups. The results of learning curve analysis indicated a shift towards consistent success after the 82nd case, reaching an acceptable rate of failure by the 118th case.
    Conclusion: The findings of this study suggest that DAA can offer benefits but there is a learning curve. Complications were initially high but began decreasing after approximately 80 cases. Careful selection of patients is critical, particularly in the effort to minimize being presented with a challenging case. This study provides insights that may be helpful to surgeons when considering DAA; however, further study is warranted.

    Cement Filling Technique to Prevent Greater Trochanter Displacement in Hip Arthroplasty for Femoral Intertrochanteric Fracture: A Technical Note

    Byung-Chan Choi, MD , Kyung-Jae Lee, MD , Eun-Seok Son, MD , Byung-Woo Min, MD

    Hip Pelvis 2024; 36(3): 223-230
    Abstract
    With the increasing use of primary hip arthroplasty for management of intertrochanteric fractures, firm fixation and union of the greater trochanteric (GT) fragment are required during hip arthroplasty for management of intertrochanteric fractures. Various methods have been suggested to address this issue. However, displacement of the GT is a frequent occurrence. We have introduced a cement-filling technique for performance of hip arthroplasty of the proximal femur for achievement of immediate firm fixation of the GT. Cement filling during performance of hip arthroplasty for management of femoral intertrochanteric fractures is a valuable technique for preventing displacement of the GT and to encourage early mobilization.

    Kee Hyung Rhyu, M.D.*, Woo Young Chae, M.D., Kye Young Han, M.D.

    J Korean Hip Soc 2008; 20(4): 278-285
    Abstract
    Purpose: We wanted to compare the clinical and radiological outcomes of using compression hip screws with those of using Targon proximal femoral nails for the treatment of intertrochanteric fracture of the femur.
    Materials and Methods: From April 2001 to December 2005, we reviewed 93 patients who suffered with intertrochanteric fracture and they had a minimum follow up for 6 months (47 cases of Targon® proximal femoral nail (Group 1) and 46 cases of compression hip screw (Group 2) ) Both groups were compared with regard to the operation time, the number of transfusions, pain as analyzed by the visual analogue scale (VAS), the timing of maximum tolerable weight-bearing and the complications. Radiological assessment was directed toward the time of boney union, and we also assessed the changes observed between the immediate postoperative roentgenograms and final follow-up roentgenograms according to various parameters
    Results: Group 1 had significantly better clinical results for the mean operation time, the number of transfusions and the mean time to self ambulation. Radiologically, there were fewer complications such as a medially displaced femoral shaft, cut out of the lag screw and nonunion in Group1
    Conclusion: Better clinical and radiological results can be achieved with using Targon proximal femoral nails compared with that of using compression hip screws for the treatment of intertrochanteric fracture of the femur
