Abstract
The Total Hip Arthroplasty (THA) has become one of the most reliable surgical interventions that has improved the quality of life in many patients. THA allows patients to have increased mobility, range of motion, and reduced pain in patients with degenerative hip joints. This surgical procedure has become an effective treatment option for several chronic conditions affecting the hip joint. Although this surgery has been shown to give promising results in patients with hip pathology, selecting the approach for THA is a critical step in pre-operative planning. The best approach for this surgical procedure depends on multiple factors and each present with their own challenges, success rates, and limitations. To further elucidate the advantages and disadvantages associated with different surgical approaches, we critically review each surgical approach along with the different causes of failure of the THA procedure.

Abstract
OBJECTIVE Multiple hemivertebrae (MHV) is defined as three or more hemivertebrae, and is relatively uncommon among patients with congenital scoliosis. This study aimed to compare the natural history of different kinds of MHV and describe the surgical outcome of MHV. METHODS In this retrospective cohort study, a total of 50 patients diagnosed with MHV were enrolled from June 2007 to June 2018. The medical records and radiographs of these patients were reviewed to summarize the characteristics of MHV. Patients with MHV were divided into the unbalanced (UB) group, partially unbalanced (PUB) group, and completely balanced (CB) group. Medical records and radiographs of MHV patients were reviewed to collect HV position, natural history, coronal and sagittal parameters. A Mann-Whitney U test was used to compare the radiographical data, such as the cobb angle of main curve and secondary curve, and Fisher's exact test was used to compare the patients in different kinds of MHV with surgical indication or not. RESULTS The average number of hemivertebrae was 3.6 and the average main curve was 57.5°. Twenty-four of 50 patients had associated anomalies, including four patients with sacral agenesis, one with tetralogy of Fallot, two with congenital imperforate anus, and 17 with Klippel-Feil syndrome. In 22 patients who underwent MRI imaging, three patients had mild syringomyelia and three patients had diastematomyelia. The UB and PUB groups had a larger main curve and compensatory curve than the CB group. Of the 25 patients with follow-up before surgery, the curve progression rate was highest in the UB group (12.1°/year) but similar in the PUB group (4.2°/year) and CB group (3.6°/year). All patients in the UB and PUB group met the criteria for surgery. In contrast, only 10 of 23 patients in the CB group had surgical indications. Eighteen of the 37 patients with surgical indications chose to undergo surgery and the correction rate of the main curve was 51.4%. CONCLUSIONS Early surgical intervention should be considered for most patients with UB or PUB MHV. For patients with CB MHV, surgical treatment may not be urgently needed at the first visit. Posterior hemivertebrectomy could be used for the treatment of MHV with satisfying radiographic outcome.

Anatomical variants complicating the posterior approaches towards the elbow joint. Surg Radiol Anat 2023; 45:587-592. [PMID: 36920516 PMCID: PMC10130116 DOI: 10.1007/s00276-023-03124-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 03/02/2023] [Indexed: 03/16/2023]
Abstract
INTRODUCTION Anatomical variants observed during the posterior approach to the elbow joint require special attention due to their clinical relevance. We aim to present a compendious review of described variants potentially encountered during the posterior approach towards the elbow joint to the experts in the elbow surgery. METHODS A narrative review of surgical and anatomical textbooks, as well as search of scientific databases was carried out. RESULTS Variability of the subcutaneous nerves is important during incision planning. Accessory muscles such as dorsoepitrochlearis, chondroepitrochlearis, epitrochleoanconeus, subanconeus or supernumerary flexor carpi ulnaris may confuse even the senior surgeon during the dissection and possibly complicate the fracture reduction. Some bony variants such as supratrochlear foramen may lead to fracture or possibly interfere with the osteosynthesis placement. Accessory bones are also present in the region of the elbow joint. Those situated intra-articular may present with symptoms. CONCLUSION Many variants can be encountered in the area of the elbow joint and their knowledge is essential to truly understand its anatomy. The presented review enables easier orientation in the current literature with the aim on the posterior approach towards the elbow joint.

Arch Orthop Trauma Surg 2023; 143:1671-1678. [PMID: 35377048 DOI: 10.1007/s00402-022-04419-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 03/06/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Recurrent hip dislocation after multiple revision total hip arthroplasty is a severe complication. Therefore, constrained acetabular liners (CL) have been used during salvage procedures. We report our experience of constrained liners in a re-revision setting with focus on re-dislocation. We also evaluated acetabular and femoral bone loss as potential risk factor. METHODS Between January 2013 and December 2016, 65 patients were treated in a single institution for revision and re-revision hip arthroplasty using CL. The indication for using a CL was a high risk of re-redislocation after multiple recurrent hip dislocation including failed Dual Mobility Cups (DMC). Compromising soft tissue defects as well as severe bone defect were therefore regarded as high risks. Thirty-eight patients (77.6%) underwent a minimum of three surgical procedures before the index revision procedure. Sixteen patients (24.6%) were excluded as they were lost to follow-up, expired before minimum follow-up or refused study participation, leaving 49 patients in the analysis (75.4%). The mean follow-up was 62 months (44-74; SD = 7.7). We assessed the following potential risk factors for revision or dislocation: type of surgical setting (septic/aseptic), BMI, cup inclination angle, size of liner used and acetabular and femoral bone loss according to Paprosky classification. The primary endpoints were dislocation or repeat revision for any reason. RESULTS Of the 49 patients, we found an overall re-revision rate of 40.8% (20/49) and a dislocation rate of 30.6% (15/49). There were no significant differences among the surgical re-revision rate or dislocation rate as a factor of patient characteristics. In terms of bone loss, there was a trend towards higher revision rates for increasing acetabular and femoral bone loss, but without statistical significance. CONCLUSIONS We found the use of a constrained liner in a re-revision setting still bears a high risk of re-revision and re-dislocation. Therefore we restrained from using constrained liners in favour of Dual mobility cups. In this study there was no significant higher dislocation rate in the subgroup of periprosthetic infection. Furthermore the rigid design of a constrained liner bears the known risk of structural failure of acetabular reconstruction implants. Severe acetabular or femoral bone defects seem to have an impact on the revision rate, but not on the dislocation rate with regards to the restored offset and center of the hip. Results have to be taken into context such that the study population inherently has a predisposition for poorer outcomes. Indications should be strongly filtered for patients at high risk for recurrent hip joint dislocation including failed DMCs with only limited bone loss and moderate soft tissue defects. Our modification to the existing classification with a high inter and intraobserver reliability will make future studies more comparable regarding revisions and bone stock loss. Still further research using objective and reproducible parameters is needed to better analyze data especially in the background of complex revision hip arthroplasty.

Abstract
Posterior malleolus fractures are frequent injuries, present in 7-44% of all ankle fractures. The objective of this study is to review the evidence to indicate the fixation of this fracture and to choose the appropriate surgical approach. The classic indications for fixation were fragment size greater than 25-30% of the articular surface and displacement greater than 2mm. However, current evidence suggests that, rather than size, factors such as syndesmotic instability, intra-articular step-off greater than 1-2mm, plafond impaction and the presence of intercalary fragments should be considered. When comparing the different surgical approaches, the literature supports the use of posterior approaches and reserves the recommendation of the traditional approach for exceptional cases. For the treatment of this injury it is essential to know the anatomy of the ankle and to consider all the factors described above, in addition to the presence of concomitant injuries.

Cervical alignment and clinical outcome of open-door laminoplasty vs. laminectomy and instrumentation in kyphotic multilevel cervical degenerative myelopathy. Arch Orthop Trauma Surg 2023; 143:1429-1440.

Abstract
INTRODUCTION The aim of this study was to determine whether the sagittal lordotic alignment, clinical outcomes and axial symptoms (AS) could be improved by kyphotic correction through the posterior approach for the treatment of multilevel cervical degenerative myelopathy (CDM) and to further analyze the changes of cervical spinal alignment parameters after correction of kyphosis. The hypothesis was that correction of kyphosis can improve the severity of AS and neurological recovery. MATERIALS AND METHODS We retrospectively reviewed 109 patients who suffered from multilevel CDM combined with kyphosis. The patients had undergone open-door laminoplasty (Group LP, 53 patients) and laminectomy with instrumentation (Group LI, 56 patients) between January 2014 and December 2018. Cervical spinal alignment parameters, including curvature index (CI), T1 slope, C2-7 Cobb angle, C2-7 SVA, were measured on the pre- and postoperative lateral radiographs. The recovery rate was calculated based on the Japanese Orthopedic Association (JOA) score. AS severity was quantified using Neck Disability Index (NDI). A P value less than 0.05 was considered to be significant. RESULTS Analyses of postoperative follow-up data showed significant differences (P < 0.001) in CI, correction of CI, C2-7 Cobb angle, T1 slope, C2-7 SVA and NDI between Group LP and LI, but no significant differences in JOA score (P = 0.23) and recovery rate (P = 0.13). There were significant differences (P < 0.001) in CI, T1 slope, C2-7 Cobb angle, C2-7 SVA, JOA score, and NDI between pre- and postoperative follow-up in both groups. Correction of CI showed negative correlation with AS severity (r = -0.51, P < 0.001), and no association with recovery rate (r = 0.14, P = 0.15). CONCLUSIONS Satisfied neurological improvement was achieved by LP and LI for multilevel CDM combined with kyphosis. Cervical kyphotic correction produced significant improvement of AS and increase of T1 slope and C2-7 SVA. However, the kyphotic correction may not be associated with better neurological recovery in the short-term postoperative period.

Abstract
BACKGROUND Current literature lacks objective criteria to determine surgical management in patients with ankylosing spondylitis who sustain cervical fractures. The purpose of our study was to analyze the determinants for stratifying surgical approach, evaluate the outcome in patients, and postulate a management strategy. METHODS This was a retrospective study of patients with ankylosing spondylitis who underwent surgery for cervical spine injury with a minimum follow-up of 2 years. Neurological recovery, fracture pattern including translation and angulation, surgical duration, blood loss, and postoperative complications were recorded, and a comparative analysis of these factors with anterior, posterior, and combined surgical approaches was performed. RESULTS The study included 43 men with a mean age of 57 years; 49% underwent anterior-only stabilization, 16% underwent posterior-only stabilization, and 35% underwent combined anteroposterior stabilization. Mean operative time was significantly lower in anterior-only (81.4 minutes; P < 0.05) and posterior-only (124 minutes; P < 0.05) approaches compared with combined approach (266.6 minutes). Mean blood loss was significantly lower in anterior-only (87.5 mL, P < 0.05) approach compared with posterior-only (714.7 mL) and combined (912.7 mL) approaches. Mean translation was 1.8 mm, 1.7 mm, and 3.7 mm in anterior, posterior, and combined approaches (P < 0.05), respectively. CONCLUSIONS Our study provides insights into management of cervical spine fractures in ankylosing spondylitis patients. A fracture displacement ≤2 mm may be successfully managed by an anterior approach, while the posterior approach may be beneficial in similar fractures warranting instrumentation extending to the thoracic spine. All other fractures warrant a combined surgical approach.

Abstract
BACKGROUND For posterior pilon fractures, the posterior approach (PA) is widely used but has its limitations. The transfibular approach (TFA) has been adopted to treat posterior malleolar fractures for the advantage of direct visual confirmation of the reduction status intraoperatively, yet the report of its application on posterior pilon fractures is rare. This study aims to compare TFA with PA in terms of their corresponding reduction quality. METHODS Clinical data of 85 posterior pilon fracture patients treated via PA (n = 62) or TFA (n = 23) were retrospectively reviewed. Radiographic and clinical assessments, including articular step-off or gap, syndesmosis reduction quality, signs of ankle arthritis, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), ankle stability, and the active range of motion (ROM) of the ankle, were all evaluated by two readers independently. RESULTS The total incidence of step-off or gap ≥ 1 mm was significantly higher in the PA group (35.5%) than in the TFA group (8.7%, p = 0.015). In all the patients, step-off ≥ 1 mm was identified as an independent risk factor for the development of arthritis and a lower AOFAS score (p < 0.001). No significant difference was found in ROM and complication incidence between the two groups. Ankle instability was found in neither group during the follow-up. CONCLUSION TFA could offer a way to intraoperatively evaluate the reduction status with direct visual confirmation and, thereby, might improve the results of reduction for posterior pilon fractures. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Intervertebral release (IVR) in the apical region is critical for full release of a rigid spine. Previous studies have mainly reported IVR techniques using an anterior approach or posterior apical convex IVR. We first report the surgical procedure of posterior multisegment apical convex plus concave IVR combined with posterior column osteotomy (PCO) for treating rigid thoracic/thoracolumbar scoliosis. METHODS This study retrospectively analyzed clinical, radiologic outcomes and technique notes of 18 patients with rigid scoliosis treated with posterior multisegment convex plus concave IVR combined with PCO. RESULTS The preoperative, postoperative, and final follow-up mean sagittal Cobb angles of the main curve were 75.2° (58.7°-110.2°), 18.4° (9°-35.1°), and 19.0° (8.2°-36.3°), respectively. The mean correction rate was 75.3% (66.7%-86.7%). In cases of thoracolumbar kyphosis, the preoperative, postoperative, and final follow-up mean sagittal Cobb angles were 45.7° (40.5°-52.6°), 18.8° (10.2°-27.5°), and 19.8° (11.1°-29°), respectively. The mean correction rate was 57% (42.1%-72.6%). The mean axial vertebral rotation (AVR) in the IVR region was 24.4° (14.3°-46.3°) preoperatively and was corrected to 10.9° (10.9°-26.6°) postoperatively. The mean correction rate for AVR was 55.9% (41.1%-78.6%). The coronal and sagittal Cobb angles and AVR postoperatively were significantly lower than those preoperatively (P < 0.001). This case series reported 2 cases of pleural effusion and 1 case of wound infection. CONCLUSIONS Single posterior multilevel apical convex plus concave IVR combined with PCO is a safe and effective surgical method for treating rigid thoracic/thoracolumbar scoliosis that does not need 3-column osteotomy.

Abstract
Background Prior investigations of total hip arthroplasty (THA) have studied the effects of prosthetic femoral head size and stem offset on hip range of motion (ROM), impingement risk, and overall hip stability to optimize the return to activities of daily living. However, the relationship between femoral head length and hip ROM, specifically external rotation (ER), has not been evaluated. The aim of our study was to intraoperatively assess how femoral head length affects hip ROM during a posterior approach THA. Methods Thirty-two patients undergoing a primary elective THA through a posterior approach were prospectively included. After final femoral stem insertion, femoral head trials were performed using the targeted head length, followed by the shorter (-3.0 to -3.5 mm) and longer (+3.0 to +4.0 mm) head length configurations. At each length, hip ER was measured using an intraoperative goniometer from an imageless navigation system. ER values across the three head lengths were compared using a repeated-measures analysis of variance and paired t-tests. Results Varying femoral head lengths demonstrated a statically significant and reproducible effect on intraoperative ER range (analysis of variance; P < .001) in each patient. An increased femoral head length (mean 3.4 mm) significantly decreased (P < .001) ER range by 10.8 ± 3.3° while a shortened femoral head length (mean 3.5 mm) significantly increased (P < .001) the ER ROM by 6.0 ± 3.8°. Conclusions The results of this study demonstrate the sensitivity of hip ROM to incremental changes in femoral head length. As ER is important for activities of daily living, inadvertent lengthening should be avoided.

Abstract
Thoracic ossification of the posterior longitudinal ligament (OPLL) is a rare condition that is mainly accompanied by cervical OPLL or ossification of thoracic ligamentum flavum. In case of causing neurological manifestations, it is preferred to treat the condition surgically. Several surgical procedures were introduced, including anterior, posterior, or combined approaches. Laminectomy with instrumented fusion is the most popular procedure utilized via the posterior approach. A 32-year-old obese woman, who suffered from back pain and weakness in both lower extremities for one month, was referred to our spine outpatient clinic. Imaging revealed lower thoracic OPLL (T7/T8 & T8/T9 & T9/T10). The posterior longitudinal ligament had a mixed ossification pattern (beaked and continuing cylindrical). To maintain thoracic spine stability and prevent future kyphosis, we performed laminectomy and long segment fixation (T7 to T12). The post-operative neurological examination revealed a considerable increase in muscle strength and significant pain relief.

Abstract
Aim We aimed to examine the safety and effectiveness of a posterior approach alone in the surgical treatment of sacral-presacral tumors. In addition, we investigate factors that determine the selection of a posterior approach alone. Materials and Methods Patients with sacral-presacral tumors who underwent surgery in our institution between 2007 and 2019 were examined in this study. Data regarding patient age, gender, tumor size (>6 cm and <6 cm), tumor localization (below or above S1), tumor pathology (benign or malignant), surgical approach (anterior alone, posterior alone, or combined), and extent of resection were recorded. The Spearman's correlation analyses were conducted between surgical approach and tumor size, localization, and pathology. Factors influencing the extent of resection were also examined. Results Complete tumor resection was achieved in 18 of 20 patients. A posterior approach alone was used in 16. No strong or significant relation was detected between surgical approach and tumor size (r = 0.218; P = 0.355). There was no strong or significant relationship between surgical approach and tumor localization (r = 0.145; P = 0.541) or tumor pathology (r = 0.250; P = 0.288). Tumor size, localization, and pathology were not independent factors that determined surgical approach. The only significant independent determining factor for incomplete resection was tumor pathology (r = 0.688; P = 0.001). Conclusion A posterior approach is safe and effective in the surgical treatment of sacral-presacral tumors independent of tumor localization, size, or pathology and is a feasible first-line treatment option.

Abstract
BACKGROUND AND PURPOSE A tendon-sparing modification of the posterior approach to the hip joint was introduced in the specialist hip unit at our institution in 2016. The SPAIRE technique-acronym for "Saving Piriformis And Internus, Repair of Externus" preserves the insertions of gemellus inferior, obturator internus, gemellus superior and piriformis intact. We compare the results of the first 285 hip hemiarthroplasty patients, unselected but preferentially treated by our hip unit surgeons using the SPAIRE technique, with 567 patients treated by all orthopaedic surgeons (including the hip unit) in the department over the same 3.5 year period using the standard lateral approach. We report length of stay, return to pre-injury level of mobility, place of residence and mortality at 120 days. PATIENTS AND METHODS The review included all hemiarthroplasty patients. Pre-fracture mobility and place of residence, surgical approach, grade of senior surgeon in theatre, stem modularity, acute and overall length of stay, mobility, place of residence, re-operations and mortality at 120 days were recorded. Data were obtained from the National Hip Fracture Database that included a telephone follow-up at 120 days and from electronic patient records. RESULTS The odds of returning to pre-injury level of mobility were higher in the SPAIRE technique group than in the standard lateral group; adjusted odds ratio (95% confidence interval (CI)) 1.7 (1.1 to 2.7, p = 0.01). INTERPRETATION When used in hip hemiarthroplasty, the SPAIRE technique appears safe and may confer benefit in maintaining the pre-injury level of mobility over the standard lateral approach.

Abstract
Mucopolysaccharidosis encompasses multiple lysosomal storage disorders that are relevant to the orthopedic surgeon as they lead to disruption in bone and cartilage development. These patients may present with early-onset joint pain, including end-stage hip arthritis warranting total hip replacement. The altered hip anatomy in this disorder is of specific importance to the arthroplasty surgeon as it presents challenges when reconstructing the proximal femur and acetabulum and informs implant choice. We present a 17-year-old patient with end-stage bilateral hip arthritis who underwent staged bilateral total hip arthroplasty. We discuss technical considerations in surgical technique and the consequences of acetabular and femoral deformity on implant selection.

Abstract
Background Posterior only surgery has been widely performed in the treatment of thoracic and lumbar spinal tuberculosis. Surgical options include debridement with posterior instrumentation only or combined with anterior reconstruction. The aim of this study is to investigate and compare the clinical, functional and radiological outcomes using a single-stage posterior only surgery in thoracolumbar spinal tuberculosis by three different surgical techniques. Methods Patients undergoing posterior only surgery for thoracic and lumbar spinal tuberculosis were followed up prospectively and included. Three different procedures, Group-A: Posterior instrumentation with anterior cage reconstruction (n = 49), Group-B: Posterior instrumentation and anterior autologous bone-grafting (n = 21) and Group-C: Posterior column shortening without anterior-reconstruction (n = 52) were compared for kyphosis correction achieved, kyphosis at final follow-up and degree of correction lost. Neurological assessment was done using ASIA impairment Scale(AIS) grades. Functional assessment was done using Visual analogue score (VAS), Modified McNab criteria and NASS satisfaction score. Results A total of 122 patients were included in the study, Group-A (49), Group-B (21) and Group-C (52). Radiological correction of kyphotic deformity in anterior reconstruction, Group-A (20.17 ± 9.25⁰) was higher than 13.97⁰ ± 6.06⁰ and 14.27⁰ ± 6.47⁰ achieved in Groups B and C respectively. There was no significant difference in correction lost amongst the three groups (p-value, 0.76). Surgical duration, blood loss and hospital stay were significantly higher in the anterior reconstruction group (p-value, 0.001). Similarly, no significant difference was noted between the three groups in neurological and functional outcomes at 2 years. Conclusion Posterior only approach is eminently satisfactory for treating Thoracolumbar Spinal Tuberculosis (STB). All three groups had similar functional and neurological outcomes. However there was a better correction of deformity in patients with anterior cage reconstruction.

Abstract
PURPOSE The aim of this study was to assess perioperative pain and mobilization after total hip arthroplasty (THA) using three different surgical approaches. METHODS This was a multisurgeon, prospective, single-center cohort study. A total of 188 patients who underwent hip arthroplasty (THA) between February 2019 and April 2019 were analyzed according to the surgical approach used (direct anterior, lateral, and posterior approach). Outcome parameters were the daily walking distance during the inpatient stay, the pain level according to the visual analog scale (VAS) at rest and motion during the inpatient stay and at 6-week follow-up and the modified Harris Hips Score (mHHS) preoperatively and at 6 weeks. RESULTS The walking distance within the groups increased significantly during the inpatient stay (p < 0.001). The DAA and posterior approach patients had a significantly longer walking distance than the lateral approach patients on the third postoperative day (DAA vs. lateral, p = 0.02; posterior vs. lateral 3, p = 0.03). DAA and posterior approach patients reported significantly less pain during motion on the third postoperative day and at 6-week follow-up than the lateral approach patients (3 postoperative day: DAA vs. lateral, p = 0.011; posterior vs. lateral, p = 0.04; 6 weeks control: DAA vs. lateral, p = 0.001; Posterior vs. lateral 3, p = 0.005). The mHHS demonstrated significant improvement within each group. However, lateral approach patients reported significantly less improvement than the DAA and posterior approach patients (DAA vs. lateral, p = 0.007; posterior vs. lateral, p = 0.021). CONCLUSION This study analyzed perioperative pain progression and short-term rehabilitation after THA according to the different surgical approaches. Direct anterior and posterior approaches have shown comparable improvements in pain, walking distance, and mHHS. Whether this effect persists over a longer period of time must be clarified in future studies. STUDY DESIGN Prospective cohort study, level of evidence, 2.

Open Reduction for Potentially Reducible Atlantoaxial Dislocation Secondary to Transverse Ligament Laxity in Patients with Rheumatoid Arthritis. World Neurosurg 2022; 167:e789-e794. [PMID: 36038120 DOI: 10.1016/j.wneu.2022.08.097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 08/17/2022] [Accepted: 08/20/2022] [Indexed: 10/31/2022]
Abstract
OBJECTIVE Atlantoaxial dislocation (AAD) is classified into reducible AAD and irreducible AAD (IRAAD). Anterior or posterior releasing followed by occipitocervical/atlantoaxial fusion is often performed for IRAAD, but is technically demanding. This study aimed to evaluate the results of the posterior open reduction technique without releasing the atlantoaxial joint in the treatment of potentially reducible AAD (PRAAD) caused by transverse ligament laxity in patients with rheumatoid arthritis (RA). METHODS Data from 38 RA patients who experienced PRAAD due to transverse ligament laxity were retrospectively reviewed. They all underwent posterior open reduction and fusion without releasing the atlantoaxial joint. Outcomes were evaluated by using atlantodental interval, modified Japanese Orthopedic Association scores, Nurick grade, Neck Disability Index, and visual analog scale score for neck pain. RESULTS All the patients achieved solid bone fusion at follow-up. The mean atlantodental interval was reduced to 5.6 ± 0.7 mm and 2.1 ± 0.5 mm after traction and operation, respectively, from a preoperative score of 8.2 ± 0.6 mm (P < 0.05). Compared with the respective preoperative values, the mean modified Japanese Orthopedic Association score and Nurick grade were significantly increased at the final follow-up (both P < 0.05), whereas the Neck Disability Index and visual analog scale score for neck pain were significantly decreased (both P < 0.05). CONCLUSIONS AAD with partial reduction after skeletal traction for 48 hours should be defined as PRAAD, not IRAAD. Open reduction with a C1-C2 pedicle screw-rod system can be safely and effectively applied in the treatment of PRAAD due to transverse ligament laxity in patients with RA.

Orthop Traumatol Surg Res 2022; 108:103354. [PMID: 35716987 DOI: 10.1016/j.otsr.2022.103354] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 04/10/2022] [Accepted: 04/22/2022] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Minimally invasive approaches (direct anterior approach: DAA; minimally invasive anterolateral: MIAL; piriformis-sparing posterior approach: PSPA) are widely used for total hip arthroplasty (THA), with a muscle-sparing objective. There are no published comparative studies of muscle damage secondary to these approaches. The aim of the present study was to compare fatty infiltration (FI) on MRI induced by DAA, MIAL and PSPA in THA 1) in the tensor fasciae latae (TFL) and sartorius muscles, 2) in the gluteal muscles, and 3) in the pelvitrochanteric muscles. HYPOTHESIS Greater FI is induced by DAA in anterior muscles, by MIAL in gluteal muscles and by PSPA in pelvitrochanteric muscles. MATERIALS AND METHODS Three continuous prospective series of THA by DAA, MIAL and PSPA included 25 patients each. MRI was performed preoperatively and at 1 year postoperatively. FI was graded on the Goutallier classification in all periarticular hip muscles. Muscles showing ≥2 grade aggravation at 1 year were considered damaged. RESULTS Nine patients whose preoperative MRI was uninterpretable were excluded. In all, 66 patients (21 DAA, 24 MIAL and 21 PSPA) with 132 MRI scans were analyzed. TFL was damaged in 2/21 DAA patients (9.5%), 1/24 MIAL patients (4.2%) and 0/21 PSPA patients (0%). There were no sartorius lesions. The anterior third of the gluteus medius was damaged in 8/24 MIAL patients (33.3%) and the gluteus minimus in 10/24 (41.7%), compared to 1/21 DAA patients (4.8%) and 0/21 PSPA patients (0%). The mid and posterior thirds of the gluteus medius and the gluteus maximus were never damaged. The piriformis muscle was damaged in 3/21 DAA patients (14.3%), 2/24 MIAL patients (8.3%) and 2/21 PSPA patients (9.5%). The obturator internus was damaged in 4/21 DAA patients (19%), 1/24 MIAL patients (4.2%) and 16/21 PSPA patients (76.2%). The obturator externus and quadratus femoris were mainly damaged in PSPA patients: respectively, 5/21 (23.8%) and 4/21 patients (19%)). CONCLUSION The muscle-sparing properties of minimally invasive hip approaches are only theoretical. In the present series, there were rare TFL lesions with DAA and MIAL. Gluteus medius and minimus lesions were frequent in MIAL. Pelvitrochanteric muscles lesions were more frequent in PSPA, but found in all 3 approaches. These findings should help guide surgeons in their choice of approach and in informing patients about the damage these minimally invasive approaches can cause.

Abstract
Introduction This study aims to compare cup inclination achieved (1) Using two orientation guides, whilst using the same 3-point pelvic positioner and (2) Using two types of pelvic positioners, whilst measuring intra-operative cup inclination with an inclinometer. Materials and methods This is a prospective, diagnostic cohort study of a consecutive series of 150 THAs performed through a posterior approach. Two types of 3-point pelvic positioners were used (Stulberg and modified Capello Hip Positioners) and the cup was positioned freehand using one of two orientation guides (mechanical guide or digital inclinometer). Intra-operative inclination was recorded, radiographic cup inclination and anteversion were measured from radiographs. The differences in inclination due to pelvic position (ΔPelvicPosition) and orientation definitions (ΔDefinition) were calculated. Target radiographic inclination and anteversion was 40/20° ± 10°. Results There was no difference in radiographic cup inclination/ (p = 0.63) using a mechanical guide or digital inclinometer. However, differences were seen in ΔPelvicPosition between the positioners ((Stulberg: 0° ± 5 vs. Capello: 3° ± 6); p = 0.011). Intra-operative inclination at implantation was different between positioners and this led to equivalent cases within inclination/anteversion targets (Stulberg:84%, Capello:80%; p = 0.48). Conclusions With the pelvis securely positioned with 3-point supports, optimum cup orientation can be achieved with both alignment guides and inclinometer. Non-optimal cup inclinations were seen when intra-operative inclinations were above 40° and below 32°, or the ΔPelvicPosition was excessive (> 15°; n = 2). We would thus recommend that the intra-operative cup inclination should be centered strictly between 30° and 35° relative to the floor. Small differences exist between different type of pelvic positioners that surgeons need to be aware off and account for.

Abstract
OBJECTIVE To compare postoperative opioid morphine milligram equivalents (MME) prescriptions for opioid-naïve patients undergoing single-level transforaminal lumbar interbody fusion (TLIF) versus posterolateral lumbar fusion (PLF) and total postoperative MME prescribed based on operative duration. METHODS Patients undergoing single-level TLIF or PLF from September 2017 to June 2020 were identified from a single institution. Patients were first grouped based on procedure type (TLIF or PLF) and subsequently regrouped based on median operative duration. Statistical tests compared patient demographics and opioid prescription data between groups. Multivariate regressions were performed to control for demographics, operative time, and procedure type. RESULTS Of 345 patients undergoing single-level PLF or TLIF, 174 (50.4%) were opioid-naïve; 101 opioid-naïve patients (58.0%) underwent PLF and 73 (42.0%) underwent TLIF. Patients undergoing TLIF received more opioid prescriptions (1.99 vs. 1.26, P < 0.001) and total MME (91.2 vs. 66.8, P = 0.002). After regrouping patients based on operative duration, independent of procedure type, there were no differences in postoperative opioid prescriptions, and Spearman rank correlation coefficient between total MME and operative duration was r = 0.014. Multivariate analysis identified TLIF as an independent predictor of increased postoperative opioid prescriptions (β = 0.64, P < 0.001), prescribers (β = 0.49, P = 0.003), and MME (β = 24.4, P = 0.030). CONCLUSIONS Opioid-naïve patients undergoing single-level TLIF receive a greater number of postoperative opioids than patients undergoing single-level PLF, and TLIF was an independent predictor of increased postoperative opioid prescribers, prescribers, and MME. There were no differences in postoperative opioid prescriptions when assessing patients based on operative duration.

Abstract
Background Prosthesis dislocation following total hip arthroplasty (THA) is one complication that affects treatment outcome and increases the cost of treatment. Currently, many surgeons prohibit patients from performing floor-based activities; however, these prohibitions might affect the lifestyle of a number of patients. Objective This study aimed to evaluate the ability of floor sitting after THA, and factors associated with this ability. Methods This study was a retrospective cohort study, evaluating 240 patients who underwent THA with a posterolateral approach, in a single tertiary hospital. Patient demographic data, preoperative clinical data, prostheses type, and postoperative radiographic were extracted from the electronic medical records. Postoperative ability to perform floor sitting was evaluated at 6 months postoperatively. Results There were 52 patients (21.66%) who were able to sit on the floor postoperatively. Multivariate logistic regression analysis showed independent association between three factors with ability to sit on the floor after surgery: pre-operative external rotation range of motion (OR 1.03; 95% CI, 1.01-1.06; P = 0.01), pre-operative Harris Hip Scores (OR 1.05; 95% CI, 1.01-1.10; P = < 0.01), pre-operative ability to sit on the floor (OR 10.2; 95% CI, 3.65-28.5; P = < 0.01). Conclusion There were a number of patients who could sit on the floor after THA. However, there were factors which were associated with this ability. Hence, these results could be useful for adjusted patient preoperative expectations, and did not preclude all patients to perform floor activities.

Abstract
BACKGROUND Management of posterolateral tibial plateau quadrant fractures can be challenging, and two posterior approaches were frequently used for exposure, reduction, and fixation: posterolateral approach and posteromedial approach. The purpose of this study was to compare their deep anatomical structure and analyze their limits and the risk of injury to important structures during surgical dissection of two approaches. METHOD Five lower limb specimens were used in this study. After dissection of the skin and superficial fascia of each specimen, deep structures were dissected via posteromedial and posterolateral approach, and several parameters including perpendicular distance from the anterior tibial artery coursing through the interosseous membrane fissure to the lateral joint line and apex of fibular head and so on were measured and analyzed. RESULT The perpendicular distance from the ATA coursing through the interosseous membrane fissure to the lateral joint line was 49.3 ± 5.6 mm (range 41.3-56.7 mm), while the distance to the apex of fibular head was 37.7 ± 7.2 mm (range 29.0-48.0 mm). The transverse distance of the anterior tibial vascular bundle is around 10 mm. The perpendicular distance from the top accompanying vein of the ATA bundle to lateral joint line and apex of fibular head was 44.1 ± 6.3 mm and 32.5 ± 7.6 mm, respectively. The maximum proportion of posterolateral tibial plateau shielded by the fibular head from the posterior view was 61.7 ± 4.9% (range 55.6-64.1%). The average length of popliteus muscle outside the joint was 83.1 ± 6.0 mm (range 76.5-92.2 mm), and the width in the middle was 28.1 ± 4.3 mm (range 26.6-29.1 mm). CONCLUSION Although posterolateral approach seems more direct for exposure of posterolateral quadrant tibial plateau fracture, it has three major disadvantages in deep dissection. Posteromedial approach through the medial board of medial head of gastrocnemius-soleus may be safer, but it was hard for direct visualization of articular surface which limits it usage for only a few cases.

Abstract
PURPOSE To compare the clinical, radiological and functional outcomes of three-column osteotomy (3CO) by a single-stage posterior approach in patients with isolated congenital angular kyphosis (CK) and healed post-tubercular kyphosis (PTK). METHODS The hospital records of 30 patients with isolated congenital kyphosis (Group CK) and 51 patients with healed post-tubercular kyphosis (Group PTK), operated at a single centre utilizing a 3CO by a single-stage posterior-only approach, were retrospectively analysed. The two groups were compared with respect to selected demographic variables with clinical, radiological and functional outcome measures at a minimum follow-up of 24 months. RESULTS Patients in Group CK (median: 13 years, range: 4-30 years) presented earlier than those in Group PTK (median: 16 years, range: 6-45 years). The apex of the deformity was most often located in the thoracic spine in Group PTK, and in the thoracolumbar or lumbar spine in Group CK. The mean operative time (198.2 ± 31.5 min v/s 174.4 ± 34.5; p = 0.01) and estimated blood loss (859.6 ± 312.2 ml v/s 720.8 ± 187.3; p = 0.04) were significantly higher in Group PTK. While the local kyphosis angle was significantly corrected with surgery in both groups, the correction was significantly better in Group CK-this group also had significantly better overall functional (SRS-22r) scores at a follow-up of 24 months (p < 0.05). The overall complication rate (29.4% v/s 23.3%) and neurological complication rate (9.8% v/s 6.6%) were higher in Group PTK. Permanent neurological deterioration occurred in one patient in each group. CONCLUSION Patients with PTK have significantly higher age of presentation, higher operative time and higher complication rate as compared to CK. However, good functional outcomes and kyphosis angle correction can be achieved in both the groups with posterior-only three-column osteotomies.
