Evidence in literature is contradicting regarding outcomes of total knee arthroplasty (TKA) in post-traumatic osteoarthritis (PTOA) and whether they are inferior to TKA in primary osteoarthritis (OA). The aim of this review was to find out if any difference exists in the results of TKA between the two indications. The electronic databases MEDLINE, EMBASE, The Cochrane Collaboration, and PubMed were searched and screened in duplicate for relevant studies. The selected studies were further subjected to quality assessment using the modified Coleman method. The primary outcome measure was patient reported outcome, and secondary outcome measures were infection, revision, stiffness, and patella tendon rupture.Introduction and Objective
Materials and Methods
Hip fractures in elderly patients are managed at both major trauma centers (MTC) and trauma units (TU). Previous evidence has demonstrated the importance of early surgery to reduce the morbidity and mortality related to the injury. The aim of this study is to compare the ‘time to theatre' and ‘30 day mortality' in TUs versus MTC in UK. A retrospective review of prospectively collected data on NHFD was performed. The average ‘time to theatre' in hours and ‘30 day mortality' of all hospitals were analysed between January and December 2018. Further subgroup analysis was done to check for any regional variations; in each instance a Shapiro-Wilk test was used to check for normal distribution, followed by a one-way ANOVA with a Tukey's post hoc test. Data from 158 hospitals in England (ENG), Wales (WAL) and Northern Ireland (NI) were used; 18 of which were MTC. There were 57,936 operative cases in TUs and 8606 in MTC's. The mean time (hours) to surgery from presentation was 32.51 and 32.64 for TUs and MTC respectively (p=0.513). There was no significant difference in ‘30 day mortality' (p=0.635) between TUs (6%) and 5.7% MTC's (5.7%), MTC's and TUs in ENG, WAL and NI (p=0.555), and MTC and WAL, NI and the different regions of ENG (p=0.209). A significant difference was observed, between the regional practice for TUs versus MTC's in ENG, WAL and NI (p=0.001) and between MTC's and TUs in WAL, NI and the different regions of ENG (p=0.001), with patients waiting significantly longer in NI for their procedure (mean=60.25 hours, p=0.001) There was no significant difference in time to surgery or 30 day mortality between TUs and MTC's, demonstrating comparable hip fracture care, despite MTCs need to prioritise more serious injuries.
Scapholunate instability is a common form of carpal instability and Brunelli procedure has been advocated as a surgical intervention for this difficult problem. Twenty five patients with clinical and radiological diagnosis of scapholunate dissociation were included in the study. Mean age of the patients was 37 years. All the patients were treated by modified Brunelli procedure, with the flexor carpi radialis tendon being passed through a drill hole in scaphoid and sutured to radiotriquetral ligament. All patients had a wrist arthroscopy prior to the index procedure and associated injuries recorded. The average postoperative follow up for the patients was 60 months.INTRODUCTION
MATERIALS AND METHODS
Internal fixation of pertrochanteric fractures is evolving as newer implants are being developed. Proximal Femoral Nail Antirotation (PFNA) is a recently introduced implant from AO/ASIF designed to compact the cancellous bone and may be particularly useful in unstable and osteoporotic hip fractures. This study is a single and independent centre experience of this implant used in management of acute hip fractures. 68 patients involving 68 PFNA nailing procedures done over a period of 2 years (2007–09) were included in the study. Average follow-up period of patients was 1 year. AO classification for trochanteric fractures was used to classify all the fractures. Radiological parameters including tip-apex distance and neck shaft angle measurement were assessed.Introduction
Methods
A detailed clinical examination and investigations are required to evaluate the cause of persisting groin pain following a metal on metal (MoM) hip replacement. Adverse reaction to metallic debris (ARMD) is an emerging problem with MoM hip replacements. It is an umbrella term encompassing metallosis, pseudo-tumors and aseptic lymphocytic vasculitis associated lesions (ALVAL). The role of imaging in the diagnosis of this complex problem is still unclear. A study was undertaken to evaluate the efficacy of ultrasound in diagnosis of ARMD following a MoM hip replacement. The study group included 35 patients with a clinical and histological diagnosis of ARMD, who had a preoperative ultrasound. All ultrasound procedures were performed on the anterior and lateral aspects of the painful hip with a high frequency probe of 9–13 MHz (Sonoline Antares – Siemens).INTRODUCTION
METHODS
Ultrasonography for rotator cuff disease is a cheap and non-invasive investigation. Our study investigates the tendon specific pathologies leading to misinterpretation of ultrasound findings and their implication for the surgical management. On hundred and five consecutive patients who had an ultrasound scan by a single musculoskeletal radiologist and then underwent shoulder arthroscopy by a single shoulder surgeon for rotator cuff pathologies were included. Surpraspinatus Tendon (SST): There was a sensitivity of 90%. The relatively low positive predictive value (76%) and specificity (42.5%) were influenced by a high number of false positives. This was a mixed group of 23 cases, in which ultrasonography had described either a full-thickness (FTT) or partial-thickness (PTT) tear when arthroscopy did not show any evidence for a cuff tear. Seven of these cases were described as FTT with dimensions less than 1 cm and in ten cases the radiologist described a “possible sub-centimetre tear”. Subscapularis Tendon (SSC): There was a specificity of 100%. The poor negative predictive value (78%) and sensitivity (26%) were caused by a high number of false negatives. Further analysis of the 20 “false negative” patients showed four FTT and sixteen PTT. All partial thickness tears involved the superior fibres of the subscapularis tendon. Our results confirm that USG is a reliable investigation in larger full thickness tears, particularly of the superior rotator cuff (SST). The reliability is significantly reduced in sub-centimetre tears and partial thickness tears, particularly of the subscapularis tendon. Associated tendon pathologies like intra-tendinous calcifications and intra-substance tears make an accurate diagnosis even more difficult and add to the tendency to ‘over-diagnose’ tears of the rotator cuff with use of ultrasonography. The shoulder surgeon should be aware of the potential misinterpretation of ultrasonography findings and be prepared to adjust the surgical procedure accordingly.
Fractures of humeral shaft are commonly seen in orthopaedic practice accounting for approximately 3% of all fractures. Treatment of these injuries continue to evolve as advances are made in both nonoperative and operative management. We performed a prospective study in the management of fractures of diaphysis of humerus by interlocking nail fixation and dynamic compression plating (DCP) was undertaken over a period of 3 years. Forty five patients with humerus fracture were treated with either interlocking nailing or plating. Rodriguez-Merchan et al criteria was used to compare results of both groups postoperatively. Fractures with unacceptable alignment was the most common indication for operative intervention (53%). While only 50% of the interlocking group had healed by 16 weeks, 75% of the plating group had united by this time. Overall results (Rodriguez-Merchan) show 65% excellent and good results in interlocking group and 93% similar results in the plating group. Postoperative radial nerve palsy was not seen in the interlocking group but was noted in 6.25% of the plating group. All of them recovered uneventfully with time. Plating is generally considered gold standard and to have predictable results in treatment of humerus shaft fractures. We have noted earlier union and better overall results in the plating group. Interlocking nailing is particularly preferable in communited, segmental and pathological fractures.
