There is no clear evidence on indications and outcomes of hip arthroscopy in sequelae of Legg-Calve-Perthes disease (LCPD). The aim of the current study was to evaluate current literature on the role and outcome of hip arthroscopy in LCPD. A literature search using four databases was conducted in April 2020, focusing on the role of hip arthroscopy in sequelae of LCPD. A systematic search was carried out in confirmation with the Cochrane Collaboration, Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of nine studies were included in the systematic review. The total number of hip arthroscopies performed for LCPD was 109. The mean age of included patients was 34.8±7.88 years (7-58 years). Recalcitrant hip pain was the main indication for surgery, followed by pain and stiffness. The most common finding in arthroscopy was labral tears, followed by osteochondral lesions of femoral head or acetabulum and intra-articular loose bodies. Consequently, debridement of labrum tears chondroplasty for cartilage defects and osteoplasty for impingement from deformed femoral head (hinged abduction) were commonly performed. A significant improvement in hip function was seen in all studies. Pooled data of Harris hip score showed significant improvement after surgery was conducted.Hip arthroscopy may be beneficial in patients having symptoms of impingement secondary to changes in labrum, femoral head or acetabulum. Limited evidence shows improved function and range of motion after surgery. This treatment has been found to be safe in terms of complication rates and improvement may persist for years.

Background: Several methods of measurement of anteversion of acetabular components after total hip arthroplasty (THA) have been described in the literature using plain radiographs or computed tomography (CT) scans. None of these have proved to be the gold standard. We aimed to study the correlation between the CT and radiographic methods of calculation of acetabulum anteversion. Methods: CT scans of the pelvis, anteroposterior (AP) and cross-table lateral (CL) radiographs were obtained in 60 patients who underwent THA two weeks after surgery. Anteversion was measured using Widmer method and Liaw method on AP radiographs, and the ischiolateral method on CL radiographs. Anteversion measured on the CT scan was taken as the reference anteversion and the above measurements were analysed for correlation with the measurements on CT scan. Intraclass correlation coefficients (ICCs) were calculated for both intra- and interobserver reliability. Results: Mean acetabular version on CL radiographs was 53.1 ± 10.7. Mean version on AP radiographs by Widmer method was 21.4 ± 3.6 and by Liaw method was 20.3 ± 4.8. Mean version on CT scans was 26.02 ± 6.8. There was a good correlation between the acetabular version on CT scans with the version on AP radiographs by Widmer method (r = 0.78, p < 0.001) and Liaw method (r = 0.87, p < 0.001). Good correlation was seen between the acetabular version on CL radiographs and CT scans (r = 0.91, p < 0.001). Also, a good correlation was observed between the acetabular version measurements on CL radiographs and AP radiographs by Widmer method (r = 0.81, p < 0.001) or Liaw method (r = 0.70, p < 0.001). Excellent inter- and intraobserver reliability were seen for all the measurements. Conclusions Calculation of acetabular component version on AP views as well as CL views of plain radiographs showed a strong correlation with the version measurements on CT scans. Good correlations were observed between different techniques of measurement on radiographs. Therefore, all these measurements can be valid methods for assessment of anteversion.

A 38-year-old man was operated with posterior spinal decompression and pedicle screw instrumentation for his L2 fracture with incomplete neurological deficit. In the recovery, he complained of blindness in both eyes after twelve hours. Computed tomographic scan and magnetic resonance angiography revealed bilateral occipital lobe infarcts. He remained permanently blind even after three years follow-up. Though rare, perioperative vision loss is a potential complication following spine surgery in prone position. We report a rare occurrence of cortical blindness following lumbar spine surgery.

Concomitant dislocation of the tarsometatarsal and metatarsophalangeal joints of foot is an extremely rare injury. Such injuries presenting in a single or adjacent dual rays have been described in few cases previously. We describe such an injury in adjacent three metatarsals of a polytrauma patient. These injuries are likely to be missed in the initial assessment of a polytrauma patient. These patients are at risk of an overlooked diagnosis but the consequences of missing this type of injury may be quite severe. This case is presented in view of its uniqueness along with possible mechanism of injury, the sequence of reduction and follow-up. Knowledge of such injury and its proper management may be useful to the trauma surgeons.

This paper discussed the injury mechanism and management of a patient who had concomitant ipsilateral hip and knee dislocations and contralateral open leg fracture. A 32-year-old man presented with ipsilateral fracture-dislocations of the left hip (Pipkin's type IV) and knee (Moore II) joints and contralateral open fracture of the leg bones after a car accident. After emergency resuscitative measures, the hip joint was reduced and Pipkin's fracture was fixed using Ganz approach with lag screws; knee joint was reduced closely and tibial plateau fracture was stabilized with lateral buttress plate and a transarticular spanning fixator. The open fracture on the other leg was debrided and fixed with an external fixator. There was no instability in both joints after fixation when he was examined under anesthesia. The fractures united after 3 months and the patient had no residual instability of hip and knee. There was no clinical or radiological evidence of osteonecrosis in the hip joint after 6 months. At one-year follow-up, he had satisfactory functional outcome with almost normal range of motion at both joints. Ipsilateral hip and knee dislocations are rare injuries and more caution is needed for early diagnosis. A timely appropriate intervention can provide good functional outcome to the patient in this situation.

Traumatic posterior dislocation of hip associated with ipsilateral displaced femoral neck fracture is a rare injury. Moreover, the management of such patients evokes strong views regarding primary replacement or preserving the femoral head. We presented a case of young adult with such an injury. He was operated upon with reduction of the dislocation and fixation of femoral neck fracture with the help of cancellous screws. Two years later, the fracture had united and the patient was asymptomatic. We further proposed the mechanism of injury for such a fracture and discussed the management in the changing trauma scenario of the developing world.
