Fractures Proximal humerus account for nearly 10 % of geriatric fractures. The treatment options varies. There is no consensus regarding the optimal treatment, with almost all modalities giving functionally poor outcomes. Hence literature recommends conservative management over surgical options. MULTILOC nail with its design seems to be a promising tool in treating these fractures. We hereby report our early experience in the treatment of 37 elderly patients To evaluate the radiological outcome with regards to union, collapse, screw back out/cut through, implant failures, Greater tuberosity migration. To evaluate the functional outcome at the end of 6 months using Constant scoreAbstract
Background
Objectives
Elective operating was halted during the COVID-19 pandemic to increase the capacity to provide care to an unprecedented volume of critically unwell patients. During the pandemic, the orthopaedic department at the Aneurin Bevan University Health Board restructured the trauma service, relocating semi-urgent ambulatory trauma operating to the isolated clean elective centre (St. Woolos’ Hospital) from the main hospital receiving COVID-19 patients (Royal Gwent Hospital). This study presents our experience of providing semi-urgent trauma care in a COVID-19-free surgical unit as a safe way to treat trauma patients during the pandemic and a potential model for restarting an elective orthopaedic service. All patients undergoing surgery during the COVID-19 pandemic at the orthopaedic surgical unit (OSU) in St. Woolos’ Hospital from 23 March 2020 to 24 April 2020 were included. All patients that were operated on had a telephone follow-up two weeks after surgery to assess if they had experienced COVID-19 symptoms or had been tested for COVID-19. The nature of admission, operative details, and patient demographics were obtained from the health board’s electronic record. Staff were assessed for sickness, self-isolation, and COVID-19 status.Aims
Methods
Surgeons fixing scaphoid fractures need to be familiar with its morphological variations and their implications on safe screw placement during fixation of these fractures. Literature has limited data in this regard. The purpose of this CT-based study was to investigate scaphoid morphometry and to analyse the safe trajectories of screw placement in scaphoid. We measured the coronal and Sagittal widths of scaphoid in CT-scans of 60 patients using CT based data from 50 live subjects with intact scaphoid. Safe placements for screws with diameters of 1.7mm, 2.4mm, 3.5mm and 4mm were studied using trajectories with additional 2mm safety corridor.Introduction
Methods
To assess the effectiveness of role of frozen section in revision arthroplasty. 21 patients with infected hip arthroplasties were operated in the form of one or two-staged revision hip arthroplasties. A frozen section was obtained intra-operatively and >5 PMN's/ HPF was considered as a positive indicator of infection. Fig 1 llustrating frozen section image. If the frozen section was reported negative (≤5 PMN's/HPF), the revision prosthesis was implanted after a thorough debridement and a wash. If the frozen section was reported as positive, after the debridement a non-articulating antibiotic loaded cement spacer was implanted for 8 weeks, supplemented with 3 weeks of intravenous antibiotics and 3 weeks of oral antibiotics. This was followed by an antibiotic free interval of 2 weeks. The patient was taken up for a revision surgery once the frozen section study was negative (≤5 PMN's/HPF). The patients were followed up for minimum of 1 year to a maximum of 2 years after the revision for any evidence of infection (assessed clinically and serologically, radiologically).Aim

Optimal management of acute patellar dislocation is still a topic of debate. Although, conventionally it has been managed by non-operative measures, recent literature recommends operative treatment to prevent re-dislocations. Our study recommends that results of non-operative measures comparable to that of operative management. Our study is the retrospective with 46 consecutive patients (47 knees) of first time patellar dislocation managed between 2012 and 2014. The study methodology highlighted upon the etiology, mechanism of injury and other characteristics of first time dislocations and also analysed outcomes of conservative management including re-dislocation rates. The duration of follow up ranged from 1 to 4 years. Average age at first-time dislocation was 23 years (Range 10–62 years). Male:Female ratio was 30:17. Twisting injury was the commonest cause. 1 patient required open reduction but all others relocated spontaneously or had successful closed reduction. Medial Patello-Femoral Ligament injury was frequent associated feature. 11 knees Conservative management of primary patellar dislocation is successful in majority of patients. Surgery should be reserved for the carefully selected patients with specific indications.
To reduce several disadvantages many surgeons are not using tourniquet in TKA. Here we compared functional outcome along with pain and blood loss in sixty patients. 60 patients who underwent TKA wererandomized into a tourniquet group (n2 = 30) and a non-tourniquet group (n1 = 30). All operations were performed by the samesurgeon and follow-up was for 6 month. Primary outcomes werefunctional and clinical outcomes, as evaluated by KSS and postoperative pain. Secondary outcomes were blood loss, surgical time and visibility, extensor lag and Knee ROM, DVT and radiolucency.Introduction
Material and Method
To demonstrate the role of an antibiotic containing bone substitute, native bone active proteins and muscle transforming into bone.
Recurrent osteomyelitis was eradicated and filled with a gentamycin eluting bone substitute (Cerament™l G) consisting of sulphate and apatite phases and covered by a muscle flap. C2C12 muscle cells were seeded on the bone substitute in-vitro and their phenotype was studied. Another muscle cell line L6 was seeded with osteoblast conditioned medium containing bone active proteins and specific markers were studied for bone differentiation.
A chronic, longstanding, fistulating osteomyelitis was operated with radical eradication and filling of the cavity with gentamycin eluting bone substitute. At one year, the patient had no leg pain and a healed wound. Significant bone was also seen in the overlaying muscle, at one month post-op disappearing after 6-months. Local delivery of gentamycin had a protective effect on bone formation. C2C12 cells seeded on the gentamycin eluting bone substitute depicted no difference in proliferation when compared to plain bone substitute and expressed 4 folds higher Alkaline phosphatase (ALP) compared to controls. C2C12 cells expressed proteins and genes coding for collagen type 1 (Col 1), osteocalcin (OCN), osteopontin (OPN) and bonesialoprotein (BSP). L6 cells cultured with osteoblast conditioned medium remained uninucleated and expressed osteoblastic proteins like Col 1, OCN, OPN and BSP.
Bone substitute with gentamycin leads to differentiation of mesenchymal cells into bone in-vitro. Native bone active proteins from an osteoblast culture can induce differentiation of muscle cells in-vitro. Clinical observations with rapid bone formed in the bone substitute and in some cases in the muscle are a consequence of both leakage of bone active proteins and also from osteoprogenitor cells coming from the overlaying muscle interacting with the osteoinductive bone substitute.
Role of intra-articular Tranexamic acid in total knee replacement arthroplasty Prospective evaluation was done to see the effect of intra-articular Tranexamic acid on blood loss in 60 patients (120 knees) undergoing total knee arthroplasty. All the patients were operated by one surgeon with same technique by using same implants. Patients were randomly injected 1500 mg/20 ml of Tranexamic acid on one side of the knee only. Nothing was injected on the contra lateral knee. Evaluation was done for swelling and the amount of blood loss in the drain.Background:
Materials and methods
Modified posterior approach and its effect on stability and functional outcome in total hip arthroplasty. A retrospective comparative evaluation was done to assess the functional outcome and rate of dislocation in 233 hips (Group A) operated before 2007 by convention posterior approach and 567 hips (Group B) were operated by modified posterior approach.(2007–2011) In this modified posterior approach technique, 2–3 stay sutures (non-absorbale Nylon) are applied in the piriformis tendon, short external rotator and proximal part of Quadratous muscle. Then a conjoint- myocapsular sleeve is raised by starting cutting (with cautery) linearly over the capsule with adherent fibers of gluteus minimus to piriformis tendon, short rotators and part of quadratus to expose and dislocate the head. After inserting the definite prosthesis, upper part of sleeve (capsule, piriformis tendon) is sutured with same nonabsorbable Nylon at the lower part of tip of greater trochanter by passing through the bone with needle or by drilling the bone; lower part of the sleeve is tied with lateral trochanteric bone. Additional stability to repair was given by closing the tendinous part of the gluteus maximus by horizontal cross mattress sutures up its attachment to the proximal femoral shaft.Background:
Material & Methods:
To validate accuracy of transepicondylar axis as a reference for femoral component rotation in primary total knee arthroplasty. A prospective study done from dec 2010 to dec 2011 at tertiary centre. 80 knees were included (43 females and 21 males). All surgeries were carried out by one senior arthroplasty surgeon. All patients undergoing primary total knee replacement were included and all revision cases were excluded. Intraoperative assessment of TEA was done by palpating most prominent point on lateral epicondyle and sulcus on medial epicondyle and passing a k wire through it. Confirmation is done under image intensifier C arm with epicondylar view. Postoperative TEA was assessed by taking CT scan, measuring condylar twist angle and posterior condylar angle. Also correlation of femoral component rotation with postoperative anterior knee pain was assessed.Purpose

Material & Methods:
In recent times there has been an increasing trend towards surgical intervention in paediatric femoral shaft fractures with widening indications. Titanium elastic nails and external fixation are two widely practiced procedures for such fractures. We report a series of 48 children with 52 fractured femurs, 18 being managed by TENS and 34 in a linear external fixator. Children were aged between 3.5 to 12 years and the fractures were stabilised after an optimal closed reduction on a normal theatre table under image intensifier control. Fracture site distribution was nearly uniform in both the groups. Though most children were assigned to any of the groups at random, external fixators were applied on many younger children and those having financial constraints.Background:
Materials & Methods:
Recurrent dislocation after hip arthroplasty is a difficult problem. The purpose of the present study was to evaluate the results with the use of a constrained cup for treatment for instability after hip arthroplasty. A prospective database of 30 patients who underwent revision hip surgery for dislocation of hip arthroplasty was kept with the surgeries taking place between Nov 2005 to Feb 2010.Introduction
Materials/Method
We hypothesised whether MIS techniques confer any benefit when treating thoracolumbar burst fractures. This was a prospective, non-randomised study over the past seven years comparing conservative (bracing:n=27), conventional surgery (open techniques:n=23) and MIS techniques (n=21) for stabilisation and correction of all thoracolumbar spinal fractures with kyphosis of >200, using Camlok S-RAD 90 system (Stryker Spine). All patients previously had normal spines, sustained only a single level burst fracture (T12, L1 or L2) as their only injury. Age range 18–65 years. All patients in both operatively treated groups were corrected to under 100 of kyphosis, posteriorly only. All pedicle screws/rods were removed between 6 months and 1 year post surgery to remobilise the stabilised segments once the spinal fracture had healed, using the original incisions and muscle splitting/sparing techniques. Patients were assessed via Oswestry Disability Index (ODI) and work/leisure activity status 1 year post fracture. The conservatively treated group fared worst overall, with highest length of stay, poorest return to work/activity, and with a proportion (5/27) requiring later intervention to deal with post-traumatic deformity. 19/27 returned to original occupation, at average 9 months. ODI 32%. Conventional open techniques fared better, with length of stay 5 days, most (19/23) returning to original work/activity, and none requiring later intervention. Average return to work was at 4 months. ODI 14%. MIS group fared best, with shorter length of stay (48 hours), all returning to original work/activity at average 2 months, and none requiring later intervention. ODI negligible. There was no loss of correction in either operatively treated groups. The Camlok S-RAD 90 system is a powerful tool for correction of thoracolumbar burst fractures, and maintains an excellent correction. MIS techniques provide the best outcomes in treating this group of spinal fractures, and offer patients the best chance of restoration to pre-fracture levels of activity.
A series of 14 patients suffering from tuberculosis of the sternum with a mean follow-up of 2.8 years (2 to 3.6) is presented. All were treated with antitubercular therapy: ten with primary therapy, two needed second-line therapy, and two required surgery (debridement). All showed complete healing and no evidence of recurrence at the last follow-up. MRI was useful in making the diagnosis at an early stage because atypical presentations resulting from HIV have become more common. Early adequate treatment with multidrug antitubercular therapy avoided the need for surgery in 12 of our 14 patients.
