C. Difficile infections in elderly patients with hip fractures is associated with high morbidity and mortality. Antibiotic regimens with penicillin and its derivatives is a leading cause. Antibiotic prophylactic preferences vary across different hospitals within NHS. We compared two antibiotic prophylactic regimens - Cefuroxime only prophylaxis and Teicoplanin with Gentamicin prophylaxis in fracture neck of femur surgery, and evaluated the incidence of C. Difficile diarrhea and Surgical Site Infection (SSI).

To assess the Surgical Site Infection and C. Difficile infection rate associated with different regimens of antibiotics prophylaxis in fracture neck of femur surgery.

Data was analyzed retrospectively. Neck of femur fracture patients treated surgically from 2009 in our unit were included. Age, gender, co morbidities, type of fracture, operation, ASA grade was collected. 1242 patients received Cefuroxime only prophylaxis between January 2009 and December 2012 (Group 1) and 486 patients received Teicoplanin with Gentamicin between October 2015 and March 2017 (Group 2). There were 353 males and 889 female patients in Group 1 and 138 males and 348 female patients in Group 2. The co morbidities in both groups were comparable. Incidence of C. Difficile diarrhea and Surgical Site Infection (SSI) was noted. Statistical analysis with chi square test was performed to determine the ‘p’ value.

C. Diff diarrhea rate in Group 2 was 0.41 % as compared to 1.29 % in Group 1. The Surgical Site Infection (SSI) rate in Group 2 was 0.41 % as compared to 3.06 % in Group 1. The comparative results were statistically significant (p = 0.0009).

Prophylactic antibiotic regimen of Teicoplanin with Gentamicin showed significant reduction in C. Difficile diarrhea & Surgical Site Infection in fracture neck of femur patients undergoing surgery.

Introduction

The purpose of this study was to identify the factors contributing to the development and progression of periacetabular osteolytic lesions and to identify which of these lesions can progress at an early stage following THA using repeated computed tomography scans. We also evaluated the accuracy of radiographs in assessing periacetabular osteolysis after THA with uncemented acetabular components and compared it with results of CT analysis.

Methods

CT scans were done in ninety-seven patients (118 hips) who had undergone primary THA between 1996 and 2004 at our hospital at a minimum of two-years postoperatively, from April to August 2006. All the CT images were acquired using high resolution multi-detector row CT (MDCT). The mean age of the patients at the time of surgery was 46.2 years (range, 21–65 years). The mean follow-up at the time of obtaining CT scan was 82.1 months (range, 18–234 months). The second CT scans were obtained in sixty three hips of 49 patients (36 males and 13 females) in 2009. The mean of patient's age was 52.7 years (range, 30 to 76 years). At the time of initial CT scan, the mean duration of implantation was 76.9 months (range, 17–156 months). The volume of periacetabular osteolysis was measured using Rapidia 3D software version. Linear wear of the PE was measured in digitalized radiographs obtained within 3 months of the surgery.

Purpose

Handgrip dynamometry has previously been used to detect pre - operative malnutrition and predict the likelihood of post - operative complications. This study explored whether a relationship exists between pre-operative pinch and power grip strength and length of hospital stay in patients undergoing hip and knee arthroplasty. We investigated whether handgrip dynamometry could be used pre - operatively to identify patients at greater risk of longer inpatient stays.

Methods

164 patients (64 male, 100 female) due to undergo lower limb arthroplasty (83 Total Knee Replacement, 81 Total Hip Replacement) were assessed in pre - admission clinic. Average measurements of pinch grip and power grip were taken from each patient using the Jamar hydraulic dynamometer (Jamar, USA). Duration of each inpatient stay was recorded. Patients with painful or disabling conditions involving the upper limb were excluded. Other clinical variables such as age and ASA grade were investigated as potential confounders of the relationship of interest and adjusted for.

An 83-year-old woman presented with acute weakness in her right hand and wrist extensors and swelling in the proximal right forearm. Nerve conduction studies confirmed compression of posterior introsseous nerve at the level of proximal forearm. MR imaging demonstrated the characteristics of lipoma which extended on the atero-lateral aspect of the right radius neck. The lesion was parosteal lipoma of the proximal radius causing paralysis of the posterior interosseous nerve without sensory deficit. In this case report, posterior inretosseous nerve palsy due to compression of a parostel lipoma was recovered after excision of the lipoma followed by intensive rehabilitation for six month. Surgical excision should be promptly performed to ensure optimal recovery from the nerve paralysis.

Flexion contracture in total knee arthroplasty (TKA) remains a challenge. Soft tissue management and additional bone resection are traditional options for flexion contracture correction. Our hypothesis was that the post implant computer aided measurements would not be significantly different to the extension angles measured at six weeks post-operatively in the follow-up clinic.

One hundred continuous TKA were performed by a single consultant using the OrthoPilot® (BBraun, Aesculap) navigation system and Columbus implants. Of the group, 45 were male and 55 were female. Average age was 68 (range 49–87), mean BMI was 32.86 (22.26–51.86) and mean Oxford score preoperatively was 42 (range 21–56) and post-operatively 28 (range15–50). Data recorded at the preoperative assessment clinic included clinical flexion contracture and Oxford scores. Intra-operatively data were recorded using the navigation system. These included pre-operative flexion and extension angles, actual bone cuts of tibia and femur (both medial and lateral), postoperative correction of flexion and extension angles and soft tissue releases. At six weeks post operation, patients were seen in the follow clinic and clinical flexion contracture and Oxford score reassessed by the Arthroplasty outcome service.

Measurements were grouped and comparisons were made using a Pearson Chi-square test. There was no relationship between post-implant extension angle measurements (by computer) and extension angles at six weeks (by goniometer) (p=0.682). Also, there was no relationship between pre-operative measurement angles collected at the pre-assessment (by goniometer) and the pre-implant angles measured on the table (by computer) (p=0.682). We found that BMI (up to 35) and postoperative Oxford scores were significantly related to the extension levels with values of (p=0.008) and (p=0.027) respectively. Pre-operative Oxford scores, pre-operative extension, amount of bony resection and soft-tissue releases did not show any significant relationship with the post-operative extension obtained at six weeks.

The conclusions that we draw from this study are that there might be other factors that are likely to influence extension lag between the operation and the follow-up at six weeks. One of the factors that we could identify was the BMI. Attention to extensor lag is important because it leads to a poorer knee function, as indicated by the Oxford scores. Despite most of the post-implant measurement angles showing no extensor lag, about 20% of our patients still had more than five degrees flexion contracture at six weeks.

Digital x-ray systems are now widely used in hospitals in the UK. Most systems have facilities to take measurements from the images that, we are lead to believe, can be used in accurate pre-operative planning. The aim of this study was to assess whether or not pre-operative planning can reliably predict the size of the implant required when using a hemiarthroplasty to treat an intracapsular hip fracture.

A magnification factor was calculated for pre-operative pelvic x-rays using typical beam to plate distance and plate to hip distance. The pre-operative digital radiographs of 188 consecutive patients who underwent a hip hemiarthroplasty were examined. The femoral head diameters of both the fractured and non-fractured sides were measured. The size of the implanted prosthesis was also recorded from the patients’ operation notes. The x-ray measurements were multiplied by the magnification factor and compared with the known size of the prosthesis. The calculated magnification factor was 128%. Attempts at estimating implant size from measurements of the fractured and non-fractured sides underestimated the size of the prosthesis by 3.0mm (CI 6.5 to −0.5) and 3.1mm (CI 6.8 to −0.6) respectively.

Many hospitals do not stock the full range of hemiarthroplasty implants on the shelf. Sizes at the extremes of the range may need to be specially ordered. It is important that the correct size prosthesis be inserted; an oversized prosthesis can increase the risk of dislocation and an undersized prosthesis will result in point loading and acetabular erosion. Our study shows that pre-operative planning consistently underestimates the size of the implant. However, the accuracy of these estimations is not sufficiently reliable, being +/− 3.5mm, to be able to accurately predict the size of the prosthesis required. Reasons for the under estimation are likely to be due to the fact that the measurement taken from the images does not account for the articular cartilage covering the femoral head. One of the factors leading to inaccuracy in the estimation is variation in patient anatomy and habitus, which affects hip to plate distance and thus the magnification factor. Also, the distance of the beam to plate will vary according to the radiographer’s positioning of the x-ray source.

In order to accurately pre-operatively plan the size of the prosthesis one would need to standardise the beam to hip distance. radio-opaque markers would need to be positioned at the level of the hip in order to accurately calculate the magnification factor. Without these modifications, we do not feel that hip prosthesis size can be accurately predicted from pre-operative images.

Scaphoid fractures are commonly seen fractures following distal radius fractures, yet its diagnosis can be difficult. The present study is to explore the diagnostic approach to suspected scaphoid fractures in a district general hospital in the UK.

This is a retrospective study. 286 Suspected scaphoid injuries were seen in our Fracture clinics. 184/286 were known to have normal x-ray findings initially and repeat x-ray in 10 days time. They were all treated as a simple case of a sprained wrist. 40 Patients out of the remaining 102 patients were noted to have scaphoid fractures on follow up x-rays and accordingly treated with cast. The remaining 62 patients were considered for further imaging. 28/102 went for bone scan, which confirmed scaphoid fracture in 4/28 cases. It also picked up other degenerative pathology in 4/28 cases. The rest of the scans were normal. 22/102 Were sent for CT scan which identified the fracture in 20 cases. CT scans provided details about the configuration of fracture, level of healing etc. MRI was performed in 12/102 cases, which confirmed fracture in 2/12 cases and bone bruising in 2/12 cases.

There is no consensus regarding the investigation of choice when a follow up scaphoid x-ray is inconclusive in diagnosing a possible scaphoid fracture. In this study we note that a bone scan does not offer much information. On the other hand MRI and CT investigations were useful. We recommend the use of an MRI investigation for a fresh injury, and a CT scan for fresh and old injuries.

Giant cell tumor of bone is a benign lesion that is ‘locally aggressive and potentially malignant’. The most common specific location of ‘GCT’ is about the knee (50–65%), followed by the distal radius (10–12%), sacrum (4–9%) and proximal humerus (3%–8%). The pelvis is recognized as an infrequent site of involvement accounting for as few as 2% to 3% of all giant cell tumors. Giant cell tumors often can reach an alarming size in the pelvis jeopardizing the surrounding structures.

Treatment options described in literature for pelvic giant cell tumors include radiation therapy; surgery with intralesional margin; surgery with an intralesional margin and physical adjuvants, and surgery with wide margins.

Following Type II (Periacetabular) resections the two preferred modes of reconstruction are either Saddle Prosthesis or Ilio femoral fusion. But, in patients with extensive periacetabular involvement with tumor extension into ilium the type II resection has to be combined with a Type I (Ilial) resection. This may result in insufficient ilium being available for reconstruction to consider either a iliofemoral fusion or a saddle prosthesis. In such situations we recommend Sacroiliofemoral fusion as a novel variation of iliofemoral arthrodesis.

We present two cases of GCT of pelvis with significant periacetabular involvement treated by Sacroiliofemoral fusion. A follow up at 2 years in both cases showed no recurrences, mean MSTS of 21 & TESS of 70.

This paper discusses the various treatment options for such extensive periacetbular giant cell tumors, operative technique for sacroiliofemoral fusion, outcome evaluation after 2 years by MSTS & Toronto Extremity Salvage scores.

Acute urinary retention (AUR) is a common complication following arthroplasty of the major joints and may lead to a delayed discharge with financial considerations not to mention the risks of sepsis – in the urinary tract and also rarely but very significantly in the joint itself. Our aim was to study the various factors associated with risk of AUR following arthroplasty.

We conducted a retrospective review of all available casenotes of patients undergoing total hip (THR) and knee arthroplasty (TKR) in a consecutive three year period. Variables noted included rate of AUR, catheterisation, urinary tract infection (UTI), urinanalysis, joint sepsis, anaesthetic type, use of patient controlled analgesia, postoperative morphine requirement, alpha blockade, past medical and urological history.

100 patients underwent THR. AUR occurred in 22%. Deep joint sepsis occurred in 1% – this patient had not been catheterised. 3% had positive urine analysis but were asymptomatic. No patients had a symptomatic postoperative UTI. 117 patients underwent TKR. AUR occurred in 19%. The rate of deep joint sepsis was 0.85%. There was one case of superficial infection. Neither of these cases was catheterised. There were no cases of postoperative UTI. There was correlation between previous AUR and incidence of AUR (p=0.95).

There was no significant correlation between past medical history and AUR contrary to reports by previous authors. The correlation between previous AUR with risk of AUR in the TKR group warrants further investigation. Catheterisation has been previously thought to be associated with infection. In our study with cefuroxime at induction and two doses postoperatively and gentamicin for catheter insertion and removal there were no cases of postoperative UTI and although deep sepsis was seen it was not associated with catheterisation either pre-operatively, perioperatively or postoperatively in AUR.

We undertook the current study to analyze the factors involved with failed previous stabilization surgery for patients with anterior or anteroinferior glenohumeral instability. Between 1997 and 2003 we treated seventy-four patients with traumatic unidirectional instability. The average age was thirty-two and the average follow up was fifty-eight months. There were sixteen females and fifty-eight males. All patients underwent a primary diagnostic arthroscopy followed by arthroscopic stabilization in forty-seven and open stabilization in twenty-seven cases. Ten had a recurrence of instability. Of these two had significant trauma. Of the remaining, six were in the arthroscopic group and two in the open procedure group.

Analyze the factors involved with failed previous stabilization surgery for patients with anterior or anteroinferior glenohumeral instability.

Between 1997 and 2003 we treated seventy-four patients with traumatic unidirectional instability. The average age was thirty-two years (range nineteen to forty-seven). There were sixteen females and fifty-eight males. The average follow up was fifty-eight months (range seven to eighty-three). All patients underwent a primary diagnostic arthroscopy followed by arthroscopic stabilization in forty-seven and open stabilization in twenty-seven cases. The arthroscopic procedure involved two Suretac II labral reattachment and capsular shrinkage using electrocautery. The open procedure involved a Bristow/Latarjet procedure using a delto-pectoral approach and reattachment of coracoid process using a single malleolar screw.

Ten patients had a recurrence of instability. Of these two had significant trauma, one each group. Of the remaining eight, six were in the arthroscopic group and two in the open procedure group. In the arthroscopic recurrence group, three had a large Hill Sach’s lesion and one a large Bankart Lesion. In the open procedure group, both had a large Hill Sach’s and Bankart’s lesion. This gave a recurrence rate of 12.7% in the arthroscopic group and 7.4% in the open group.

A large Hill-Sach lesion > 2mm is a contra-indication to arthroscopic repair and the optimum stabilisation procedure is an open repair (Bristow/Laterjet). Without a significant Hill-Sach’s lesion an arthroscopic Suretac II labral re-attachment is an effective way of achieving stability. Those who have a large Hill-Sach and significant Bankart’s lesion may need a combination of Bankart’s repair plus an extra-articular procedure like a Bristow/Laterjet procedure.

We conducted a randomised controlled trial to compare external fixation of trochanteric fractures of the femur with the more costly option of the sliding hip screw. Patients in both groups were matched for age (mean 67 years, 50 to 100) and gender. We excluded all pathological fractures, patients presenting at more than one week, fractures with subtrochanteric extension or reverse obliquity, multiple fractures or any bone and joint disease interfering with rehabilitation. The interval between injury and operation, the duration of surgery, the amount of blood loss, the length of hospital stay and the cost of treatment were all significantly higher in the sliding hip screw group (p < 0.05). The time to union, range of movement, mean Harris hip scores and Western Ontario and McMaster University knee scores were comparable at six months. The number of patients showing shortening or malrotation was too small to show a significant difference between the groups. Pin-track infection occurred in 18 patients (60%) treated with external fixation, whereas there was a single case of wound infection (3.3%) in the sliding hip screw group.

Background: To look into the incidence of lymphatic spread in Soft Tissue Sarcomas (STS) of the extremities and its relevance to the patient’s prognosis.

Patients & Methods: Retrospective review of 96 patients over a period of 5 years from 1999 to 2004 with a minimum follow up of 8 months. Complete data of every patient was reviewed with particular emphasis on lymph node and distant metastasis. All the patients were seen by one consultant and the histology reports were given by one Pathologist. 2 consultant radiologists were also involved in giving reports.

Results: There were 39 males and 57 females with an average age of 51 years. The average duration of swelling at presentation was 6 months. There was a strong family history of cancer in first degree relatives in 23 patients (24%). Liposarcoma was the commonest tumour (22) followed by Leiomyosarcoma (19), Fibro sarcoma (14), Synovial Sarcoma (12), Rhabdomyosarcoma (10), Histiocytoma (9) and other rare sarcomas. The Trojani grade of the tumours was Grade 1 = 36, Grade 2 = 39 & Grade 3 = 21. No metastasis (mets) were found during pre op. screening in 71 patients (74%) while 11 (12%) had lung mets, 9 (10 %) had lymph node involvement and 5 had liver involvement (4 %). 4 had multiple organ involvement on presentation. All except 6 patients had either wide local or radical excision of the tumour. The average interval between presentation and definitive treatment was 28 days. 9 of the patients with lymph node mets underwent nodal clearance during primary surgery. 2 turned out to be reactive hyperplasia while 7 proved to be malignant. 22 of the 71 patients (31 %) with no mets pre op. developed mets during follow up at an average duration of 11 months (11 to lungs, 8 to regional lymph nodes, 2 to liver and one to bone. 4 patients had multiple mets) In addition to this, there was local recurrence in 12 patients of whom 9 had incomplete excision during primary surgery. Of the total 15 patients who had proven lymph node mets, 5 came from Rhabdomyosarcoma, 4 from Leiomyosarcoma, 3 each from Lipo & Synovial sarcoma. The average life span in patients with lymph node involvement was 13 months in total when compared to 31 months for others. As on 31-3-2005, 39 were dead and the rest were alive. The average life span of the patients who died from the time of confirmed diagnosis was 23 months. The average life span for Rhabdomyosarcoma was 8 months, Histiocytoma was 12 months, Liposarcoma was 19 months, Leiomyosarcoma was 28 months and Synovial sarcoma was 36 months. Patients with Trojani grade 3 STS died at an average of 9 months when compared to 38 months for grade 1.

Discussion: There is a 16% spread to regional lymph nodes. It appears that lymph node involvement is indicative of micrometastatic disease elsewhere. Excision of the lymph nodes during primary surgery did not improve the life expectancy.

Conclusion:

Lymph node involvement is a poor prognostic sign

While removal of clinically suspicious lymph nodes is reasonable, there appears to be little justification for treating clinically uninvolved draining regional lymph nodes

Therapeutic lymph node dissection might be indicated as part of the palliative management

The presence of regional lymph node metastasis at any time should be interpreted as an expression of systemic tumour spread and treated palliatively only.

Purpose of Study – The unusual presentation of this case posed a diagnostic dilemma between a chronic haematoma and soft tissue sarcoma even after full investigation and biopsy. Salient points to differentiate between the two are discussed along with literature review.

Case Report – A 61 year old gentleman presented with sudden increase in size of an already existing swelling over the mid third of right leg associated with throbbing pain & foot drop of 4 months duration. There was no recent history of trauma or bleeding abnormalities but there was a vague history of injury to his leg during his late teens. Clinical signs showed features suggestive of malignancy with engorged veins and diffuse margins with complete foot drop (Fig 1 & 2). X-rays showed calcifications within the substance of the swelling along with proximal tibiofibular synostosis (Fig 3). MRI scan revealed a well encapsulated mass between the peroneal muscles mechanically compressing the common peroneal nerve (Fig 4). Trucut biopsy showed cholesterol clefts and areas of dystrophic calcification characteristic of chronic haematoma (Fig 5). Patient successfully underwent enucleation of the swelling along with cutaneofascial suture to obliterate the dead space leading to complete recovery of foot drop. Biopsy confirmed a Chronic Haematoma.

Discussion – Reid et al first used the term chronic expanding haematoma for haematomas that persisted and increased in size more than a month after the initiating haemorrhage. The cause of initial haemorrhage is most commonly trauma which results in displacement of skin and subcutaneous fatty tissue from more deeply located fixed fascia with formation of blood filled cysts surrounded by dense fibrous tissue. Factors in the blood-clotting cascade are said to be associated with an inflammatory reaction leading to additional bleeding from fragile capillaries and thus to additional inflammation, hence setting up a self-perpetuating process.

Although the MRI & biopsy results in this case were reassuring, the clinical scenario of sudden foot drop with increase in pain point more towards a malignant process rather than a benign condition. Some salient points to differentiate the two include that sarcoma have no history of trauma and the duration of symptoms is longer in haematoma than sarcoma. Also, sarcomas usually involve deeper structures while haematoma occur in superficial layers. It should also be noted that several soft tissue sarcoma themselves commonly reveal haemorrhagic or cystic changes. Other differential diagnosis includes myositis ossificans and tumoral calcinosis.

Conclusion – It is difficult to differentiate between chronic haematoma and soft tissue sarcoma based on clinical findings alone. X-ray and biochemical tests are always essential to rule out any fracture or bony mass but MRI is the gold standard and biopsy is the only way to rule out a malignant tumour. Surgical excision of the swelling including the fibrous pseudocapsule along with cutaneofascial suture to obliterate the dead space is the treatment of choice for chronic haematoma because aspiration of the fluid or incomplete excision could lead to recurrence, continued growth or a chronic draining sinus with or without infection.

In the 1950s Frederick Dwyer evolved the concept of treating resistant and relapsed clubfoot by osteotomy of the calcaneum. He published the results of his medial opening wedge procedure in 1963 with a mean follow-up of five years. We present the structured, radiographic and functional results at a mean elapsed time of 27 years of 36 feet (26 patients) all operated on by Dwyer. Their mean Laaveg and Ponseti (1980) grading was 83.7%. In 94% the heel was in neutral or valgus and 86% of the feet were plantigrade. A good range of movement was present in the ankle and subtalar joints in 83%.
