Purpose

Treatment of osteomyelitis (OM) is challenging. Ilizarov bone transport is a commonly used technique for management of OM. The recently introduced limb reconstruction system (LRS) has been effectively used for management of OM. It was suggested to be easier in use and less invasive. The present retrospective study aimed to compare LRS and Ilizarov bone transport in management of femoral OM using a propensity score matched analysis.

Methods

The present retrospective study included 80 consecutive patients with femoral OM. The studied patients were managed either using Ilizarov external fixator (n = 40) or Orthofix LRS (n = 40). The clinical outcome measurements included union time, limb length discrepancy, additional operative procedures, refracture and infection.

Results

Patients in the LRS group were exposed to significantly higher frequency of bone transport (30.0 versus 15.0%) and lower frequency of acute compression and lengthening (10.0 versus 32.5%). Patients in Ilizarov group had significantly higher frequency of tobramycin pellets as compared to their counterparts. The studied groups were comparable regarding the operative complications including pin-tract infection, non-union at docking site and refracture. Patients in the Ilizarov had significantly shorter time to union (8.2 ± 3.2 versus 11.0 ± 5.6 months, p = 0.012). No statistically significant differences were found between the studied groups regarding the quality-of-life domains.

Conclusions

Use of Ilizarov external fixator and Orthofix LRS devices proved to be effective and reliable. Their influences on patients’ quality appear to be comparable.

Background

Laterality and bilaterality have been reported as prognostic variables in developmental dysplasia of the hip (DDH) outcomes. However, there is little clarity across the literature on the reporting of laterality in developmental dysplasia of the hip (DDH) due to the variability in severity of the condition. It is widely accepted that the left hip is most frequently affected; however, the true incidence of unilateral left, unilateral right and bilateral cases can be hard to quantify and compare across studies. The purpose of this study was to examine laterality accounting for graded severity in a multi-centre, international prospective observational study of infants with hip dysplasia to demonstrate the complexity of this issue.

Methods

A multi-centre, prospective hip dysplasia database was analyzed from 2010 to April 2015. Baseline diagnosis was used to classify patients into a graded laterality category accounting for hip status within the DDH spectrum.

Results

A total of 496 patients were included in the analysis; 328 were <6 months old at diagnosis and 168 were between 6 and 18 months old. Of these patients, 421 had at least one frankly dislocated hip. Unilateral left hip dislocations were most common, with 223 patients, followed by unilateral right and bilateral dislocations with 106 and 92 respectively. Stratifying these patients based on status of the contralateral hip, 54 unilateral left and 31 unilateral right dislocated patients also had a dysplastic or unstable contralateral hip. There were significantly fewer bilateral patients in the 6 to 18-month group (p = 0.0005). When classifying laterality by affected hip, bilaterality became the predominant finding, comprising 42% of all patients.

Conclusions

Findings from this multi-centre prospective study demonstrate the necessity to account for the graded severity in hip status when reporting DDH laterality. To accurately compare laterality across studies, a standardized, comprehensive classification should be established, as contralateral hip status may impact prognosis and treatment outcomes.

Level of Evidence

Level II Prognostic Study.

Purpose

Congenital accessory navicular bone (ANB) is a common variant in the foot and is prone to cause several clinical symptoms. Wearing custom-made foot orthosis is considered a desirable option; however, there is limited evidence of its effectiveness. This study aims to report the mid-term effect of foot orthosis for symptomatic pediatric ANBs.

Methods

School-age children with symptomatic ANBs combined with flexible flatfoot in the authors' institute were recruited and got custom-made foot orthosis treatment. They were followed up over 4 years. The general characteristics of these children were collected before treatment, including age, gender, and body mass index (BMI). The indicators of foot symptoms, including frequency and location of pain, visual analogue scale (VAS), arch index (AI), and hind foot valgus angle (HVA), were measured during pretreatment and at the last follow-up.

Results

Twenty-seven children were recruited for this study. After 4 years of custom-made foot orthosis treatment, significant improvements showed in pain frequency, VAS, AI, and HVA (P < 0.001). Type II ANBs showed a higher pain index pretreatment (P < 0.001) and reduced after treatment (P < 0.001).

Conclusion

Mid-term effect of custom-made foot orthosis is inspiring in clinical symptoms of pediatric congenital ANBs combined with flexible flatfoot and may be an optional nonoperative treatment.

Purpose

Vascular injuries are rarely associated with severe knee injuries; nonetheless, it is imperative to efficiently detect this condition and plan for either immediate or definitive treatment at later stages. The diagnosis and management of multiligament knee injuries still present unresolved issues, particularly in the early detection of vascular issues and the sequential stabilisation of ligaments. High-energy trauma is a frequently encountered cause, however, even low-energy trauma in those who are morbidly obese might pose a significant risk. Advancements in detection and management methods have greatly decreased the occurrence of vascular complications and amputation rates over time. MLKIs after transient knee dislocations are frequently misdiagnosed for vascular injuries, underscoring the necessity for improved diagnostic techniques to avoid avoidable amputations.

Methods

This article is a new conceptual review of vascular injuries associated with MLKIs. It provides a full overview of these conditions and includes a review of the most recent literature. We have included pertinent citations from the literature, together with suggestions derived from the latest studies. This review article had additional evaluation by proficient specialists with commendable outcomes and more than a decade of expertise in surgical techniques.

Results

This article offers a detailed overview of orthopaedic management, including new definitions and summaries of the causes, evaluation of patients, clinical assessment, identification of vascular injuries, and initial management in patients with vascular impairment following major limb and joint injuries (MLKIs).

Conclusion

MLKIs (patients with lower limb ischaemia) who have vascular damage necessitate meticulous physical assessment and sophisticated treatments in order to decrease amputation rates. Prompt identification and timely treatment of vascular lesions, namely in the popliteal artery, can substantially reduce the occurrence of amputations. Emerging research suggests that there is a heightened risk in low-energy situations, particularly amongst individuals who are extremely obese. Progress in vascular intervention has led to a reduction in amputation rates, whilst the implementation of new guidelines has enhanced identification. Thorough patient assessment is essential, utilising physical examinations and imaging techniques such as Computed tomography angiography, magnetic resonance angiography (CTA or MRA) to guide treatment decisions. MRA, in particular, is capable of identifying both vascular and knee structural damage.

Level IV, Literature reviews.

The peroneus longus graft has gained much attention in recent years as a reliable autograft for primary ACL surgery. Critics have voiced concerns related to its impact on ankle biomechanics. The current review aims to synthesize the available literature on ankle biomechanics after peroneus harvest. The quantum of evidence available shows that PL harvest does not significantly impact ankle eversion or plantarflexion strength. Its impact on gait needs to be studied more deeply before any significant conclusions can be drawn.

Introduction

Hip arthroplasty, including hemiarthroplasty and total hip arthroplasty is a common surgical procedure for patients suffering from hip joint disorders with an aim of complication free early return to activities of daily living. Various minimally invasive surgical approaches have been described to achieve this aim including a relatively new SPAIRE approach. This case series shows our technique of hip arthroplasty using the SPAIRE technique with the help of conventional instruments in an Indian Scenario at a tertiary care center in Eastern India along with our short-term functional outcomes till a follow up period of 6 months.

Materials and method

This was the prospective observational study done between May 2022 to Oct 2023 in Tata Main hospital, Jamshedpur. Total 35 patients were operated by this technique. Data including age, gender, time to return orthotic assisted mobility, Harris hip score at 2 months & any complications till the follow up of 6 months were recorded for each patient who underwent Hemiarthroplasty or Total Hip arthroplasty using the SPAIRE technique with conventional instruments for hip arthroplasty (performed by single surgeon – the senior author) in our tertiary care center.

Results

35 patients were operated during this span by using the SPAIRE technique. There were 30 cases of hip hemiarthroplasty and 5 cases of total hip arthroplasty (1 bilateral). 5 patients were lost to follow up during the period of 6 months. Harris hip score was measured for each patient at 2 months and mean Harris hip score was 83.16. Out of 35 patients, 9 patients had excellent outcome, 14 patients had good outcome and 7 patients had fair outcome. No patient had complications such as infection, delayed wound healing, periprosthetic fractures or sciatic nerve injury. One patient reported dislocation at 3 months following a fall. Mean time to return to orthotic assisted ambulation was 1.5 days for all 35 patients.

Conclusion

SPAIRE technique is one of the safe surgical approaches for primary hip arthroplasties. This minimally invasive tendon sparing approach which preserves quadricep coxa provides excellent hip stability, early return to preinjury activities. It also reduces postoperative complications such as dislocation.

Purpose

To evaluate the multimodality imaging features of chondroblastoma.

Materials and Methods

Retrospective analysis of imaging features of 52 cases of histopathologically proven chondroblastoma from 2010 to 2022 was performed. Radiographs were evaluated for lesion site, location, morphology, margins, matrix mineralization, cortical breach, periosteal reaction, eccentricity, and subarticular extension. Appearance on T1, T2 weighted and post-contrast T1 was evaluated on MRI, with analysis of peritumoral edema and joint effusion.

Results

Mean patient age was 18 years (10–57 years) with male preponderance (M = 39; F = 13). 75% (n = 39) cases involved an unfused skeleton and 25% (n = 13) affected a mature skeleton. Appendicular skeleton was involved in 88.5% (n = 46) cases and axial skeleton was involved in 11.5% (n = 6) cases with all cases involving epiphysis/epiphyseal equivalent. Radiographically, all cases were well-defined geographic osteolytic lesions with a narrow zone of transition, thin sclerotic rim and lobulated [56% (n = 29)] or smooth [44% (n = 23)] margins. Matrix calcification appreciable in 62% (n = 32) cases was ‘fluffy/smudgy’. Chondroblastoma appeared isointense (83%, n = 43) on T1 MRI with characteristically low signal and hyperintense foci within (67%, n = 35) on T2-weighted images and post-contrast enhancement [heterogeneous lobular (88%, n = 46) or septal pattern (12%, n = 6)] with all barring three lesions showing perilesional edema. None of the cases of chondroblastoma in our study developed metastasis till last follow-up (mean: 71 months).

Conclusion

Chondroblastoma has distinctive imaging appearance and is often unlike majority other cartilaginous benign lesions due to characteristic low T2 signal on MRI and associated exuberant perilesional edema.

Background

Valgus knee deformity poses great challenges in total knee arthroplasty (TKA) and requires precision in balancing of soft tissue and implant component positioning. The surgical approach used for TKA has a determinantal impact on intraoperative soft tissue balancing, postoperative knee function, and complications. We executed a systematic review and meta-analysis of current literature, which included a maximum number of studies with quantitative analysis of all possible outcomes to substantiate the current evidence of the advantage of lateral versus medial approach in TKA for valgus knee deformity.

Methodology

We performed a meticulous primary electronic search across PubMed, Emabse, Scopus, and Cochrane Library databases, and looked for the comparative studies that evaluated the medial versus lateral approach in TKA for valgus knees. Statistical analyses were executed with RevMan-5.4.1.

Results

On the evaluation of four randomized controlled trials (RCTs), two prospective and five retrospective comparative studies, our analysis revealed a better functional outcome in terms of Knee Society Score [MD 2.24, 95% CI 0.42, 4.05; p = 0.02] with the medial approach. However, comparable results were observed for two approaches with regard to Knee Society Function [MD 0.69, 95% CI − 1.77, 3.15; p = 0.58], knee flexion range of motion (ROM) [MD 3.30, 95% CI − 1.34, 7.95; p = 0.16], overall complications [OR 0.60, 95% CI 0.27,1.34; p = 0.22], wound-related complications, infection, nerve injury, periprosthetic fracture, post-operative valgus, blood loss, duration of surgery, postoperative pain, and patellar tilt for TKA in valgus knee.

Conclusion

Evidence from the currently available published data suggests that the lateral approach, compared to the medial approach in TKA for the valgus knee, does not show clear superiority.

Background

Musculoskeletal ultrasonography of the hand and wrist is becoming the trend in assessing and diagnosing most hand and wrist injuries, soft-tissue mass, and occult fractures. Its advantages include ultra-high frequency probes, noninvasiveness, cost-effectiveness, lack of ionising radiation, and portability. The patients are comfortable doing this procedure in the outpatient department, and visualising the ultrasound images increases their confidence.

Conclusions

Ultrasound has a practical and dynamic real-time diagnostic capability compared to other modalities, playing an important role in hand and wrist pathologies. Apart from the diagnostic utility, it has also been beneficial in musculoskeletal intervention procedures, such as trigger finger, carpal tunnel syndrome, and various tenosynovitis. The learning curve and limited deeper penetrations are relative limitations to ultrasound usage. More dedicated training centres and modules for future generations and CT/MRI for deeper structures are always an alternative. This article reviews the role of ultrasound in hand and wrist pathologies.

Background

The Timed 360° turn test (T-360° TT) was developed to assess balance and turning ability. Although validity and reliability have been performed in different diseases, validity and reliability have not been performed in individuals with ankle sprain (AS).

Purpose

The purpose of this study was to investigate the validity and reliability of the T-360° TT in individuals with AS.

Methods

The study included 54 individuals with AS. Participants were initially evaluated with T-360° TT, Timed Up and Go (TUG) test and Biodex Balance System (BBS). To assess test–retest reliability, the T-360° TT was performed again 5 days after the first measurement by the same assessor.

Results

At the end of the study, strong positive correlations were found between T-360° TT with TUG test and BBS (p < 0.05). In addition, T-360° TT had excellent test–retest reliability (Intraclass correlation coefficient = 0.87).

Conclusion

The T-360° TT is a valid and reliable tool for the evaluation of balance and turning ability in individuals with AS. We also think that it can be used practically in clinical settings because it is a test that can be easily and quickly performed.
