The management of comminuted metaphyseal fractures is a technical challenge and satisfactory outcomes of such fixations often remain elusive. The small articular fragments and bone loss often make it difficult for standard fixation implants for proper fixation. We developed a novel technique to achieve anatomical reduction in multiple cases of comminuted metaphyseal fractures at different sites by employing the cantilever mechanism with the help of multiple thin Kirschner wires augmented by standard fixation implants. We performed a retrospective study of 10 patients with different metaphyseal fractures complicated by comminution and loss of bone stock. All patients were treated with the help of cantilever mechanism using multiple Kirschner wires augmented by compression plates. All the patients were operated by the same surgeon between November 2020 to March 2021 and followed up till March 2023. Surgical outcomes were evaluated according to the clinical and radiological criteria. A total of 10 patients were included in the study. Since we only included patients with highly unstable and comminuted fractures which were difficult to fix with traditional methods, the number of patients in the study were less. All 10 patients showed satisfactory clinical and radiological union at the end of the study with good range of motion. One of the patient in the study had post-operative wound complication which was managed conservatively with regular dressings and oral antibiotics. Comminuted metaphyseal fractures might differ in pattern and presentation with every patient and there can be no standard treatment for all. The cantilever technique of fracture fixation is based on the principle of cantilever mechanism used in bridges and helps achieve good anatomical reduction and fixation. It provides a decent alternative when standard modes of fixation don't give desired result owing to comminuted nature of fractures and deficiency of bone stock.
External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting. This prospective case series evaluated the first 20 consecutive cases of EF removal in the outpatient clinic between 10/06/22 to 16/09/22. Regional anaesthesia using ultrasound-guided blockade of peripheral nerves was administered using 1% lidocaine due to its rapid onset and short half-life. Patients were assessed for additional analgesia requirement, asked to evaluate their experience and perceived pain using the Visual Analogue Scale (VAS).Introduction

This study was proposed to evaluate the efficacy of fibrin clot augmentation in meniscal tear using inside-out meniscal repair. A total of 35 patients with meniscus tears were operated on with inside-out meniscus repair and fibrin clot augmentation. Patients were evaluated preoperatively and postoperatively with clinical criteria, Lysholm knee scoring system, and MRI. Out of the total 35 cases, 5 cases were lost to follow up. Clinical improvement was observed in 29 out of 30 patients (96.6%). The mean Lysholm score improved significantly from 67.63 ± 6.55 points preoperatively to 92.0 ± 2.9 points postoperatively (P < 0.05) in 2 years follow-up. Follow-up MRI in all patients revealed complete healing except in 1 case where the patient presented with recurrence of symptoms such as pain and locking which resolved with partial meniscectomy. Paraesthesia in the anterior part of the knee was observed in 2 cases. (6.6%). We conclude that fibrin clot augmentation is a good cost-effective modality of treatment for repairable meniscus tears to preserve the meniscus and decrease the point contact pressure on the condyles which may prevent the early occurrence of osteoarthritis.
To evaluate the functional outcome of open humerus diaphyseal fractures treated with the Three-stitch technique of antegrade humerus nailing. This is a retrospective study conducted at the Department of Orthopaedics in D. Y. Patil University, School of Medicine, Navi Mumbai, India. The study included 25 patients who were operated on from January 2019 to April 2021 and follow-ups done till May 2022. Inclusion criteria were adult patients with open humerus diaphyseal fractures (Gustilo-Anderson Classification). All patients with closed fractures, skeletally immature patients, and patients with associated head injury were excluded from the study. All patients were operated on with a minimally invasive Three-stitch technique for antegrade humerus nailing. All patients were evaluated based on DASH score. Out of the 25 patients included in the study, all patients showed complete union. The mean age of the patients was 40.4 years (range 23–66 years). The average period for consolidation of fracture was 10.56 weeks (range 8–14 weeks). The DASH score ranged from 0 to 15.8 with an average score of 2.96. Five patients reported complications with three patients of post-operative infection and delayed wound healing and two patients with screw loosening. All complications were resolved with proper wound care and the complete union was noted. None of the patients had an iatrogenic neurovascular injury. Three-stitch antegrade nailing technique is a novel method to treat diaphyseal humerus fractures and provides excellent results. It has various advantages such as minimal invasiveness, minimal injury to the rotator cuff, fewer infection rates, minimal iatrogenic injuries, and good functional outcomes. Therefore, this treatment modality can be effectively used for open humerus diaphyseal fractures.
Osteomyelitis is an inflammatory condition accompanied by the destruction of bone and caused by an infecting microorganism. Open contaminated fractures can lead to the development of osteomyelitis of the fractured bone in 3-25% of cases, depending on fracture type, degree of soft-tissue injury, degree of microbial contamination, and whether systemic and/or local antimicrobial therapies have been administered. Untreated, infection will ultimately lead to non-union, chronic osteomyelitis, or amputation. We report a case series of 10 patients that presented with post-operative infected non-union of the distal femur with or without prior surgery. The cases were performed at Padmashree Dr. D. Y. Patil Hospital, Nerul, Navi Mumbai, India. All the patients’ consents were taken for the study which was carried out in accordance with the Helsinki Declaration. The methodology involved patients undergoing a two-stage procedure in case of no prior implant or a three-stage procedure in case of a previous implant. Firstly, debridement and implant removal were done. The second was a definitive procedure in form of knee arthrodesis with ring fixator and finally followed by limb lengthening surgery. Arthrodesis was planned in view of infection, non-union, severe arthritic, subluxated knee, stiff knee, non-salvage knee joint, and financial constraints. After all the patients demonstrated wound healing in 3 months along with good radiographic osteogenesis at the knee arthrodesis site, limb lengthening surgeries by tibial osteotomy were done to overcome the limb length discrepancy. Distraction was started and followed up for 5 months. All 10 patients showed results with sound knee arthrodesis and good osteogenesis at the osteotomy site followed by achieving the limb length just 1-inch short from the normal side to achieve ground clearance while walking. Our case series is unique and distinctive as it shows that when patients with infected nonunion of distal femur come with the stiff and non-salvage knee with severe arthritic changes and financial constraints, we should consider knee arthrodesis with Ilizarov ring fixator followed by limb lengthening surgery.
Higher uric acid levels or hyperuricemia is a product of more uric acid production, dysfunctional renal excretion, or a combination of both leading to deposition of urate crystals in the joints and kidneys and has been strongly linked with the development of gout, that is, acute inflammatory arthritis. Uric acid levels have been suggested to depend on multiple factors including lifestyle, diet, alcohol consumption, etc. As these are risk parameters for hyperuricemia and since lifestyle choices vary amongst different Indian communities, we sought to study the prevalence of hyperuricemia in these communities. Also, large-scale data (in terms of gender, age, lifestyle, community) on the prevalence of hyperuricemia in subjects amongst different community populations, Hindu, Muslim, Sikh, and Christian was generated. In a retrospective study conducted at Dr. D. Y. Patil School of Medicine & Research Centre, Navi Mumbai from April 2018 to May 2021, information was gathered from four major communities on a range of indicators including serum uric acid levels followed by a thorough multilevel logistic analysis. We evaluated uric acid levels in 10,378 patients of four different communities. Outcomes were assessed biochemically as well as clinically based on the levels of serum uric acid. The mean serum uric acid levels were highest in Sikhs (7.6 mg%, n=732) followed by Christians (7.3 mg%, n=892) and then by Hindus (5.9 mg%, n=6846) and Muslims (5.6 mg%, n=1908). About 83.7% of Christians consumed meat in a non-vegetarian diet followed by 45.7% Muslims. Percentage of Christians who binge drink were highest whereas percentage of Sikh people in the heavy drinkers’ category were 5.2%. Further, 9.5% Hindus were current smokers followed by 7.8% Sikhs who smoked at present. Overall, our study of 10,378 patients demonstrated that the serum uric acid levels varied from one Indian community to another due to varying external factors like diet, age, lifestyle, and addictions. Thus, lifestyle modification in communities with higher serum uric acid levels is highly advocated and this may reduce the healthcare burden of gouty arthritis in these communities.
Osteochondromas are benign chondrogenic lesions arising on the external surface of the bone with aberrant cartilage (exostosis) from the perichondral ring that may contain a marrow cavity also. In a few cases, depending on the anatomical site affected, different degrees of edema, redness, paresthesia, or paresis can take place due to simple contact or friction. Also, depending on their closeness to neurovascular structures, the procedure of excision becomes crucial to avoid recurrence. We report a unique case of recurrent osteochondroma of the proximal humerus enclosing the brachial artery which makes for an important case and procedure to ensure that no relapse occurs. We report a unique case of a 13-year-old female who had presented with a history of pain and recurrent swelling for 5 years. The swelling size was 4.4 cm x 3.7 cm x 4 cm with a previous history of swelling at the same site operated in 2018. CT reports were suggestive of a large well defined broad-based exophytic diaphyseal lesion in the medial side of the proximal humerus extending posteriorly. Another similar morphological lesion measuring approximately 9 mm x 7 mm was noted involving the posterior humeral shaft. The minimal distance between the lesion and the brachial artery was 2 mm just anterior to the posterio-medial growth. Two intervals were made, first between the tumor and the neurovascular bundle and the other between the anterior tumor and brachial artery followed by exostosis and cauterization of the base. Proper curettage and excision of the tumor was done after dissecting and removing the soft tissue, blood vessels, and nerves so that there were very less chances of relapse. Post-operative X-ray was done and post 6 months of follow-up, there were no changes, and no relapse was observed. Thus, when presented with a case of recurrent osteochondroma of the proximal humerus, osteochondroma could also be in proximity to important vasculature as in this case enclosing the brachial artery. Thus, proper curettage and excision should be done in such cases to avoid recurrence.
Total Knee Arthroplasty (TKA) improves the quality of life of osteoarthritic and rheumatoid arthritis patients, however, is associated with moderate to severe postoperative pain. There are multiple methods of managing postoperative pain that include epidural anesthesia but it prevents early mobilization and results in postoperative hypotension and spinal infection. Controlling local pain pathways through intra-articular administration of analgesics is a novel method and is inexpensive and simple. Hence, we assess the effects of postoperative epidural bupivacaine injection along with intra-articular injection in total knee replacement patients. The methodology included 100 patients undergoing TKA randomly divided into two groups, one administered with only epidural bupivacaine injection and the other with intra-articular cocktail injection. The results were measured based on a 10-point pain assessment scale, knee's range of motion (ROM), and Lysholm knee score. The VAS score was lower in the intra-articular cocktail group compared to the bupivacaine injection group until the end of 1-week post-administration (p<0.01). Among inter-group comparisons, we observed that the range of motion was significantly more in cocktail injection as compared to the bupivacaine group till the end of one week (p<0.05). Lysholm's score was significantly more in cocktail injection as compared to the bupivacaine group till the end of one week (p<0.05). Our study showed that both epidural bupivacaine injection and intra-articular injection were effective in reducing pain after TKA and have a comparable functional outcome at the end of 4 weeks follow up. However, the pain relief was faster in cases with intra-articular injection, providing the opportunity for early rehabilitation. Thus, we recommend the use of intra-articular cocktail injection for postoperative management of pain after total knee arthroplasty, which enables early rehabilitation and faster functional recovery of these patients.
To compare the efficacy of decompression alone (DA) with i) decompression and fusion (DF) and ii) interspinous process device (IPD) in the treatment of lumbar stenosis with degenerative spondylolisthesis. Outcomes of interest were both patient-reported measures of postoperative pain and function, as well as the perioperative measures of blood loss, operation duration, hospital stay, and reoperation. Data were obtained from electronic searches of five online databases. Included studies were limited to randomised-controlled trials (RCTs) which compared DA with DF or IPD using patient-reported outcomes such as the Oswestry Disability Index (ODI) and Zurich Claudication Questionnaire (ZCQ), or perioperative data. Patient-reported data were reported as part of the systematic review, while meta-analyses were conducted for perioperative outcomes in MATLAB using the DerSimonian and Laird random-effects model. Forest plots were generated for visual interpretation, while heterogeneity was assessed using the Aims
Methods
En bloc resection for primary bone tumours and isolated metastasis are complex surgeries associated with a high rate of adverse events (AEs). The primary objective of this study was to explore the relationship between frailty/sarcopenia and major perioperative AEs following en bloc resection for primary bone tumours or isolated metastases of the spine. Secondary objectives were to report the prevalence and distribution of frailty and sarcopenia, and determine the relationship between these factors and length of stay (LOS), unplanned reoperation, and 1-year postoperative mortality in this population. This is a retrospective study of prospectively collected data from a single quaternary care referral center consisting of patients undergoing an elective en bloc resection for a primary bone tumour or an isolated spinal metastasis between January 1st, 2009 and February 28th, 2020. Frailty was calculated with the modified frailty index (mFI) and spine tumour frailty index (STFI). Sarcopenia, determined by the total psoas area (TPA) vertebral body (VB) ratio (TPA/VB), was measured at L3 and L4. Regression analysis produced ORs, IRRs, and HRs that quantified the association between frailty/sarcopenia and major perioperative AEs, LOS, unplanned reoperation and 1-year postoperative mortality. One hundred twelve patients met the inclusion criteria. Using the mFI, five patients (5%) were frail (mFI ³ 0.21), while the STFI identified 21 patients (19%) as frail (STFI ³ 2). The mean CT ratios were 1.45 (SD 0.05) and 1.81 (SD 0.06) at L3 and L4 respectively. Unadjusted analysis demonstrated that sarcopenia and frailty were not significant predictors of major perioperative AEs, LOS or unplanned reoperation. Sarcopenia defined by the CT L3 TPA/VB and CT L4 TPA/VB ratios significantly predicted 1-year mortality (HR of 0.32 per one unit increase, 95% CI 0.11-0.93, p=0.04 vs. HR of 0.28 per one unit increase, 95% CI 0.11-0.69, p=0.01) following unadjusted analysis. Frailty defined by an STFI score ≥ 2 predicted 1-year postoperative mortality (OR of 2.10, 95% CI 1.02-4.30, p=0.04). The mFI was not predictive of any clinical outcome in patients undergoing en bloc resection for primary bone tumours or isolated metastases of the spine. Sarcopenia defined by the CT L3 TPA/VB and L4 TPA/VB and frailty assessed with the STFI predicted 1-year postoperative mortality on univariate analysis but not major perioperative AEs, LOS or reoperation. Further investigation with a larger cohort is needed to identify the optimal measure for assessing frailty and sarcopenia in this spine population.
The routine use of intraoperative vancomycin powder to prevent postoperative wound infections has not been borne out in the literature in the pediatric spine population. The goal of this study is to determine the impact of vancomycin powder on postoperative wound infection rates and determine its potential impact on microbiology. A retrospective analysis of the Harms Study Group database of 1269 adolescent idiopathic scoliosis patients was performed. Patients that underwent a posterior fusion from 2004-2018 were analyzed. A comparative analysis of postoperative infection rates was done between patients that received vancomycin powder to those who did not. Statistical significance was determined using Chi-squared test. Additionally, the microbiology of infected patients was examined. In total, 765 patients in the vancomycin group (VG) were compared to 504 patients in the non-vancomycin group (NVG). NVG had a significantly higher rate of deep wound infection (p<0.0001) and associated reoperation rate compared to VG (p<0.0001). Both groups were compared for age, gender, race, weight, surgical time, blood loss, number of levels instrumented, and preop curve magnitude. There were significant differences between the groups for race (p<0.0001); surgical time (p=0.0033), and blood loss (p=0.0021). In terms of microbiology, VG grew p.acnes (n=2), and serratia (n=1), whereas NVG grew p.acnes (n=1) and gram positive bacilli (n=1). The remaining cultures were negative. The use of intraoperative vancomycin powder in adolescent idiopathic scoliosis appears to contribute significantly to deep wound infection prevention and reduction of associated reoperations. Based on this study's limited culture data, Vancomycin does not seem to alter the microbiology of deep wound infections.
Fracture dislocation of the knee involves disruption of knee ligaments with associated tibial plateau fracture. If these injuries are not evaluated swiftly, can result in a limb-threatening injury. The aim of this study is to look at the clinical outcomes of a single surgeon case series at a major trauma centre. Prospectively collected data was analysed for a 5-year period. Primary outcome measures used were International Knee Documented Committee (IKDC) score and Knee Injury & Osteoarthritis Outcome Score (KOOS). The secondary outcome measures include Tegner activity scale, knee range of movements and complications.Abstract

Methods
Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Eighty-seven patients with knee dislocation were treated at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 4 weeks was preferred unless the patient was too unstable (Injury severity score>16). The collaterals were repaired and augmented using a variety of autografts, allografts or synthetic grafts. PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score.Abstract

Background
Objective
Management of gap non-union of the tibia, the major weight bearing bone of the leg remains controversial. The different internal fixation techniques are often weighed down by relatively high complication rates that include fractures which fail to heal (non-union). Minimally invasive techniques with ring fixators and bone transport (distraction osteogenesis) have come into picture as an alternative allowing alignment and stabilization, avoiding a graduated approach. This study was focused on fractures that result in a gap non-union of > 6 cm. Ilizarov technique was employed for management of such non-unions in this case series. The Ilizarov apparatus consists of rings, rods and kirschner wires that encloses the limb as a cylinder and uses kirschner wires to create tension allowing early weight bearing and stimulating bone growth. Ilizarov technique works on the principle of distraction osteogenesis, that is, pulling apart of bone to stimulate new bone growth. Usually, 4–5 rings are used in the setup depending on fracture site and pattern for stable fixation. In this study, we demonstrate effective bone transport and formation of gap non-union more than 6 cm in 10 patients using only 3 rings construct Ilizarov apparatus. This case study was conducted at Dr. D. Y. Patil Medical Hospital, Navi Mumbai, Maharashtra, India. The study involved 10 patients with a non-union or gap > 6 cm after tibial fracture. 3 rings were used in the setup for the treatment of all the patients. Wires were passed percutaneously through the bone using a drill and the projecting ends of the wires were attached to the metal rings and tensioned to increase stability. The outcome of the study was measured using the Oxford Knee scoring system, Functional Mobility Scale, the American Foot and Ankle Score and Visual Analog Scale. Further, follow up of patients was done upto 2 years.Introduction and Objective
Materials and Methods
Injuries to the hamstring muscle complex are common in athletes, accounting for between 12% and 26% of all injuries sustained during sporting activities. Acute hamstring injuries often occur during sports that involve repetitive kicking or high-speed sprinting, such as American football, soccer, rugby, and athletics. They are also common in watersports, including waterskiing and surfing. Hamstring injuries can be career-threatening in elite athletes and are associated with an estimated risk of recurrence in between 14% and 63% of patients. The variability in prognosis and treatment of the different injury patterns highlights the importance of prompt diagnosis with magnetic resonance imaging (MRI) in order to classify injuries accurately and plan the appropriate management. Low-grade hamstring injuries may be treated with nonoperative measures including pain relief, eccentric lengthening exercises, and a graduated return to sport-specific activities. Nonoperative management is associated with highly variable times for convalescence and return to a pre-injury level of sporting function. Nonoperative management of high-grade hamstring injuries is associated with poor return to baseline function, residual muscle weakness and a high-risk of recurrence. Proximal hamstring avulsion injuries, high-grade musculotendinous tears, and chronic injuries with persistent weakness or functional compromise require surgical repair to enable return to a pre-injury level of sporting function and minimize the risk of recurrent injury. This article reviews the optimal diagnostic imaging methods and common classification systems used to guide the treatment of hamstring injuries. In addition, the indications and outcomes for both nonoperative and operative treatment are analyzed to provide an evidence-based management framework for these patients. Cite this article:
As the peak of the COVID-19 pandemic passes, the challenge shifts to safe resumption of routine medical services, including elective orthopaedic surgery. Protocols including pre-operative self-isolation, COVID-19 testing, and surgery at a non-COVID-19 site have been developed to minimize risk of transmission. Despite this, it is likely that many patients will want to delay surgery for fear of contracting COVID-19. The aim of this study is to identify the number of patients who still want to proceed with planned elective orthopaedic surgery in this current environment. This is a prospective, single surgeon study of 102 patients who were on the waiting list for an elective hip or knee procedure during the COVID-19 pandemic. Baseline characteristics including age, ASA grade, COVID-19 risk, procedure type, surgical priority, and admission type were recorded. The primary outcome was patient consent to continue with planned surgical care after resumption of elective orthopaedic services. Subgroup analysis was also performed to determine if any specific patient factors influenced the decision to proceed with surgery.Aims

Radiotherapy has contributed with a significant and impressive stride to the survival rates of oral cancer patients. However, quality and alterations in the biochemical composition of bones used for dental implantation after radiotherapy in cancer patients is always a critical and debatable factor. The aim of this study was to determine compositional alterations in human mandible bone after irradiation using Raman microspectroscopy. A total of 36 bone biopsies (21-control, 4-cancer and 11-irradiated) obtained from 36 patients during implant surgery were used. Raman measurements were carried out using a Bruker Senterra LX200 dispersive Raman spectrometer. Data acquisition points were determined under pathological supervision. Three measurements from different locations were conducted with a spot size of 10 microns. Spectra were acquired for 60s and averaged over 5-accumulations. Both mineral and matrix constituents were analysed by computing area associated with of phosphate (958 cm-1), carbonate (1070 cm-1), collagen (amide III) and matrix (amide I) bands using in-house MATLAB-based software. Unpaired student ‘t’ test was employed to measure level of significance.Background

The objectives of this study are to ascertain primary caregivers' understanding of risks associated with home trampoline use; to educate caregivers in regard to documented literature based risks associated with home trampoline use; and to evaluate if this information will have any influence on their future regulation of home trampoline use for their children. One hundred primary caregivers of patients treated in the paediatric orthopaedic surgery outpatient clinic at London Health Sciences centre were surveyed. All caregivers in clinic were invited to participate. The only exclusion criteria was the inability to provide consent. Caregivers' baseline perceptions on the risks associated with home trampoline use were assessed using a questionnaire. Caregivers then received an information pamphlet outlining documented trampoline safety data. They were then sent the same questionnaire to complete within one week of reading the pamphlet. Using our research electronic database capture (Redcap), the results of the surveys were compiled and analysed using spss 22, paired t-test and repeated measures anova. A sample size of 55 was calculated to result in a power of 80%. Of primary caregivers surveyed, 36% owned a home trampoline, and only 5% had personal experiences with their child sustaining a trampoline injury. Pre-education, when caregivers were asked on a scale of one (not dangerous) to 10 (very dangerous) how dangerous they felt a trampoline was for their child, the average response was six. Post-education, this number changed to eight. Providing education to primary caregivers significantly changed their perceptions on all sections of the questionnaire, yet 47% of primary caregivers were willing to allow their child to use a trampoline at home despite their new understanding of trampoline injury and safety. Providing education to primary caregivers significantly changed their perceptions on all trampoline safety questions, indicating effective comprehension. Despite caregivers' understanding of the risks associated with home trampoline use, approximately half of the study population continue to permit this activity for their children. There is potential to reduce paediatric orthopaedic injuries associated with home trampoline use if safer trampoline related practices are implemented based on information provided.
Previous studies have individually shown extracorporeal shockwave therapy (ESWT) to be beneficial for mid-substance Achilles tendinopathy, insertional Achilles tendinopathy or plantar fasciitis. The purpose of this pragmatic study was to determine the efficacy of ESWT in managing the three main causes of refractory heel pain in our routine clinical practice. 236 patients (261 feet) aged between 25 – 81 years (mean age 50.4) were treated in our NHS institute with ESWT between April 2014 and May 2016. They all underwent a clinical and radiological assessment (ultrasonography +/− magnetic resonance imaging) to determine the primary cause of heel pain. Patients were subsequently categorized into three groups, mid-substance Achilles tendinopathy (55 cases), insertional Achilles tendinopathy (55 cases) or plantar fasciitis (151 cases). If their symptoms were recalcitrant to compliant first line management for 6 months, they were prescribed three consecutive ESWT sessions at weekly intervals. All outcome measures (foot & ankle pain score, EQ-5D) were recorded at baseline and 3-month follow-up (mean 18.3 weeks, range 11.4 to 41).Background
Methods
We investigated whether an alternative tension band wire technique will produce greater compression and less displacement at olecranon (elbow) fracture sites compared to a standard figure of eight tension band technique. Olecranon fractures are commonly treated with tension band wiring using stainless steel wire in a figure of eight configuration. However recently published studies have raised doubts over the validity of the tension band concept proving that the standard figure of eight configuration does not provide fracture compression when the elbow is flexed. We propose an alternative tension band technique where the figure of eight is applied in a modified configuration producing greater compression across the fracture. An artificial elbow joint was simulated using artificial forearm (ulna) and arm (humerus) bones. The design simulated the action of the muscles around the elbow joint to produce flexion and extension. There were two arms to this investigation. (1) Standard tension band wire configuration with stainless steel. (2) Modified tension band wire configuration with stainless steel. The simulated elbow was put through a range of movement and sensors measured the compression at the articular and non-articluar surfaces of the fracture. Measurements were taken for compression with different weights applied to challenge both the techniques of tension band wiring. Measurements from the non articular surface of the fracture demonstrated greater compression with alternative tension band technique. However it was not statistically significant (ANOVA). Compression at the articular surface of the fracture exhibited statistically significant (p<0.05) greater compression with the alternative technique. Neither technique produced greater compression during flexion of the simulated elbow. The alternative tension band wiring technique proved superior in providing greater compression over the fracture site.
In the early 2000s hip resurfacing became an established bone conserving hip arthroplasty option particularly for the fit and active patient cohort. The performance of second-generation metal-on-metal bearings had led to the reintroduction of hip resurfacing. The Birmingham Hip resurfacing (BHR) was introduced in 1997. This was followed by a number of different designs of the hip resurfacing. The Durom hip resurfacing was introduced in 2001. These two designs had different metallurgical properties, design parameters particularly clearance and different implantation techniques. Data from joint registries show that both prosthesis perform well. Our objective was to perform a retrospective survival analysis comparing the Birmingham to the Durom hip resurfacing and analyse the mode of failures of the cases revised.Introduction

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

Management of failed total ankle replacements (TAR) remains a difficult challenge. Ankle arthrodesis, revision TAR, debridement and amputation are all utilized as surgical options. The purpose of the study was to review a series of failed TAR surgically managed in our tertiary referral centre. A retrospective review of 18 consecutive failed TARs, either within or referred to our institution, which required surgical management were reviewed. The average age was 58.2 (range 25–77) with 11 males and 6 females.Background

In 2009 the Smart Toe implant was introduced as an option for lesser toe fusion in our department. The Smart Toe is an intramedullary device made from Nitinol, an alloy that can change shape with a change of temperature, expanding within the intramedullary canals of the proximal and middle phalanx to achieve fixation. The advantages of the Smart Toe are that patients are spared 6 weeks with K-wires protruding from their toes and there is no need for wire removal. We conducted a retrospective review of radiographic and clinical outcomes to assess the performance of this implant. We present a consecutive series of 192 toe fusions using the Smart Toe implant in 86 patients, between January 2009 and November 2013. All radiographs and case notes were reviewed to assess for radiological fusion, satisfactory clinical outcome and complications.Introduction:

Recent published studies have examined the normal dimensions of the syndesmosis on CT. However, previous anatomical studies have shown variations of the articulating facets within the tibialae fibularis and may contribute to the false appearance of increased spacing within the syndesmosis. In this study, we measured and compared anterior and posterior distances of the distal tibiofibular(DTF) syndesmosis on MRI and CT imaging. We identified adult patients who had had both a CT scan and an MRI scan of their ipsilateral ankle to investigate symptoms Introduction:

and two female; mean age 33.67 years (24.6 to 42.7)) were treated
operatively by fixation of the clavicular fracture alone. Outcome
was assessed using the Herscovici score, which was also related
to changes in the GPA at one year post-operatively. The mean Herscovici score was significantly better three months
and two years after the injury in the operative group (p <
0.001
and p = 0.003, respectively). There was a negative correlation between
the change in GPA and the Herscovici score at two years follow-up
in both the conservative and operative groups, but neither were
statistically significant
(r = -0.295 and r = -0.19, respectively). There was a significant
difference between the pre- and post-operative GPA in the operative
group (p = 0.017). When compared with conservative treatment, fixation of the clavicle
alone gives better results in the treatment of patients with a floating
shoulder. The GPA changes significantly with fixation of clavicle
alone but there is no significant correlation between the pre-injury
GPA and the final clinical outcome in these patients. Cite this article:
Distal radius fractures are typical and frequent fracture of elderly woman with reduced bone density. Thus implant fixation is more difficult. Dorsal and radial comminution are frequent in these patients and so reduction and angle stable osteosynthesis needed. The angle stable plate, often also multidirectional is today the most common stabilisation device. Because of the introduction of bulky and bended implants as the Micronail or Targon DR wich require difficult opening of the bone with awles we decided to test the XS radius nail witch is a 4,5mm or 3,5mm straight nail and witch is introduced after guide wire placement and over drilling with a canulated drill of the same diameter. It is locked parallel to the joint in 3 different directions with angular stability with threaded wires. Methods 16 radius sawbones were osteotomised corresponding to a A3 Fracture and stabilised with a angle stable plate (8) and XS nail (8). 1000 alternating load cycles from 20–200N were performed and the deformation was registered. Also a FE analysis with the MSC Patran/Marc softwere were performed. Also the calculated deformation in the FE study was 20% lower. Also deformation amplitude was lower with 0.31mm compared to 0.42mm in the plate group. The differences however were not significant. Both devices show good biomechanical results. The XS nail has the advantage of mainly intraosseus position, simple operation technique with introduction over a guide wire from the proc. Styloideus radii and over drilling with a canulated drill of the same size. The exposure of the N rad. superf. must be performed. First clinical evaluation is presented. Due to the results we developed a anatomically adapted XS radius nail. The results of the first 100 patients are presented. Both angular stable plate and XSR nail can be used in unstable distal radius fracture fixation. The mainly intraosseus position of the nail and saving of the pronator quadratus as well as lower deformation are in favour of the XSR nail. However frontal plane fractures and very comminuted fractures are better treated with a multidirectional locking plate due to technical reasones so that we use the XSR nail mainly in A3 and C1 fractures.Conclusions
The aim of the study was to highlight the absence of an important pitfall in the Advanced Trauma Life Support protocol in application of rigid collar to patients with potentially unstable cervical spine injury. We present a case series of two patients with ankylosed cervical spines who developed neurological complications following application of rigid collar for cervical spine injuries as per the ATLS protocol. This has been followed up with a survey of A&E and T&O doctors who regularly apply cervical collars for suspected unstable cervical spine injuries. The survey was conducted telephonically using a standard questionnaire. 75 doctors completed the questionnaire. A&E doctors = 42, T&O = 33. Junior grade = 38, middle grade = 37. Trauma management frontline experience >1yr = 50, <1yr = 25. Of the 75 respondents 68/75 (90.6%) would follow the ATLS protocol in applying rigid collar in potentially unstable cervical spine injuries. 58/75 (77.3%) would clinically assess the patient prior to applying collar. Only 43/75 (57.3%) thought the patients relevant past medical history would influence collar application. Respondents were asked whether they were aware of any pitfalls to rigid collar application in suspected neck injuries. 34/75 (45.3%) stated that they were NOT aware of pitfalls. The lack of awareness was even higher 17/25 (68%) amongst doctors with less that 12 months frontline experience. When directly asked whether ankylosing spondylitis should be regarded as a pitfall then only 43/75 (57.3%) answered in the affirmative. We would like to emphasise the disastrous consequences of applying a rigid collar in patients with ankylosed cervical spine. The survey demonstrates the lack of awareness (∼ 50%) amongst A&E and T&O doctors regarding pitfalls to collar application. We recommend the ATLS manual highlight a pitfall for application of rigid collars in patients with ankylosed spines and suspected cervical spine injuries.
Retrospective review of growth sparing spinal instrumentation. Medical records of 30 children with spinal deformity treated were evaluated. There were 14 male and 16 female patients at an average age of 4.9 years (1-14) at the time of presentation. These included 18 idiopathic, 11 congenital and a 14 year old with delayed growth having GH treatment. All patients underwent dual growing rod construct using hook and pedicle screw instrumentation. Extensions were carried out at approximately 6 monthly intervals. Average follow up was 4.2 years (2-8.5) with an average of 7.3(3-15) extension/exchange procedures per patient. Average immediate postoperative Cobb angle was 29(15-55) from a preoperative Cobb of 68(55-100) and this was maintained to a final mean Cobb angle of 30(15-60). Average gain in T1-S1 length was 5.7(3.5-9.8) cm. Five patients had final fusion at an average age of 15.5 years. There were no infections following primary operation. Out of 249 procedures including extensions/exchange, there were 9(4.5%) episodes of deep infection in 7 patients requiring debridement. Four patients (13%) had revisions for rod breakage/screw loosening/hook pullout/junctional kyphosis and three(10%) had prominent implants.Purpose

Study Method
Tibiotalocalcaneal arthrodeisis is performed for a variety of conditions, including advanced osteoarthritis, Charcot arthropathy, rheumatoid arthritis, post-traumatic arthrosis and foot deformities such as fixed equinovarus. There have been few published studies showing the results of such a procedure for limb salvage. Over a period of 11 years between 1996 and 2007, 18 patients underwent calcaneotalotibial arthrodeisis using either cannulated screws or a retrograde intramedullary locking nail. Post-operative rehabilitation regimes were standardised. VAS, AOFAS ankle-hindfoot, SF-36 and patient satisfaction scores were obtained and analysed. Eighteen patients (10 male and 8 female) with 19 ankles underwent tibiotalocalcaneal arthrodeisis at an average age of 52.3 (31.4 to 70.2 years). Seven patients had cavovarus deformity, six had osteoarthritis, three had Charcot's joint, two had failed previous fusions and one patient had a footdrop post-T12 tumour resection. Twelve right and seven left fusions were performed, with six cannulated screws and 13 retrograde nails. The mean time to complete fusion was 5.89 (3 to 11) months in 18 ankles (94.7%). There was one pseudoarthrosis (5.3%). Patients were followed up for an average of 35.6 (11 to 144) months. Four wound infections (21%) occurred post-operatively. Two patients died from unrelated caused whilst on follow-up. Thriteen patients returned for follow-up scoring. VAS scores improved from 7.85 to 2.54 (p=0.00). AOFAS ankle-hindfoot scores improved from 30.50 to 63.62 (p=0.00). SF-36 scores also improved in several parameters. Physical function improved from 40.38 to 66.15 (p=0.02); physical role improved from 15.38 to 53.85 (p=0.03); Bodily pain improved from 36.69 to 62.23 (p=0.00); emotional role improved from 69.23 to 100 (p=0.04); and mental health improved from 62.77 to 0.15 (p=0.04). Eleven patients (84.6%) reported good to excellent satisfaction and expectation scores. Hindfoot arthrodesis, via retrograde imtramedullary nailing or cannulated screw insertion, are effective techniques for treating complex foot deformities and often is the only alternative to amputation. Although a demanding procedure with high potential complications, they provide effective relief from pain, improves the quality of life, and has high patient satisfaction.
Traditional teaching, and indeed the impression from the BOA BAPS working party report on open tibial fractures, suggests that soft tissue cover of the distal third of the leg will often need a free flap. However, more recently with the introduction of propeller flaps by Quaba, and the reintroduction of the concept of Ponten's nerve oriented flaps with the reverse sural artery flap, the role of free tissue transfer comes into question. The attraction of local flaps for distal third fractures is the reduced operating time, reduced morbidity of donor site, versatility and reliability. However, detractors would argue that muscle enhances bone union and reduces local infection. Previous reviews of lower limb soft tissue cover look at all areas of the leg. This series of 30 (14 free and 16 local flaps) cases looks exclusively at the distal third fractures, compares the complication rate of free versus local flaps and looks at the change in approach to distal third fractures with the more recently described fascio-cutaneous flaps. Our results challenge the conventional teaching and indicate that fasciocutaneous flaps can play a more active role in distal third fractures. Our study shows that the local flaps are a valuable alternative to free flaps for managing soft tissue defects in distal third fractures of tibia especially in smaller wound size and low energy fractures. The advantages are lesser operating time, reliability, versatility, lesser wound complication and osteomyelitis incidence, earlier flap cover and lesser post op morbidity leading to shorter hospital stay. The free flaps on balance are probably better with larger soft tissue defects and with more severe limb injury. This supports the use of fascio-cutaneous flaps in distal third tibial fractures.
We present an objective method for predicting the redisplacement of paediatric forearm and wrist fractures. Novel radiographic measurements were defined and their value assessed for clinical decision making. In Phase I of the study we defined the Cast Index (a/b) is the ratio of cast width in lateral view (a) and the width of the cast in AP view (b). Padding Index (x/y) isthe ratio of padding thickness in the plane of maximum deformity correction (x) and the greatest interosseous distance (y) in AP view. The sum of cast index and padding index was defined as the Canterbury Index. In Phase I, 142 children's radiographs were analysed and a statistically significant difference was identified between redisplacement and initial complete off-ending of the bones, cast index > 0.8 and padding index of > 0.3. There was no significant association with age, fracture location, seniority of surgeon or angulation. In Phase II, radiographs of 5 randomly selected cases were presented to 40 surgeons (20 consultants & 20 registrars). Following an eyeball assessment they were asked to measure the cast index and padding index (after instruction). With eyeballing the consultants predicted 33% and registrars 25% of the cases that redisplaced. After learning to measure the indices the accuracy increased to 72% for consultants and 81% for registrars (p<0.001). We conclude that the cast index, padding index and Canterbury Index are validated tools to assess plaster cast quality and can be used to predict redisplacement of paediatric forearm fractures after manipulation. They can easily be taught to orthopaedic surgeons and are more accurate than eyeballing radiographs in the clinical setting. Redisplacement can be predicted if cast index > 0.8, padding index > 0.3 and Canterbury Index > 1.1.

What was the question? The treatment of multi-injured patients requires initial stabilization of general conditions and vital parameters. The first stage in orthopedic management of the fractures in trauma involves stabilization of the bone segments to reduce blood loss and allow nursing. External fixators are fast, versatile and essential in the emergency situation in cases of multiple fractures, especially with soft tissue loss. According to damage control orthopedics (DCO) concepts, it is possible to replace an external fixator (EF) with internal synthesis (ORIF) after a period of time to reduce the risks of ORIF. However, surgery can be difficult to perform and pin sites can be the source of bone infection, in which the EF as a definitive treatment option may be considered. How did you answer the question? In trauma surgery, instability of the hardware, fractures near the joint, frame extending across the knee and the ankle, initial fixation was converted to definitive treatment with circular frames according to the Ilizarov method. Fourteen patients (2 female and 12 males; age 24 to 80 yrs, average age 43,4 y/o) were treated with various circular framses as definitive treatment: Ilizarov (2), Sheffield (7), Taylor Spatial Frame (TSF) (4) and TrueLok (1) between November 2002 and December 2007 in multiply injured patients with ISS >
20. Seven cases were femoral and seven tibial. The femoral group had four knee spanning fixator configurations and three unilateral external fixators. The tibial group had 4 unilateral frames, 1 hybrid EF, 1 across the knee EF and 1 across the ankle EF. Five patients had temporary femoral and tibial hardwares in the same side. Three patients had unilateral tibial and femoral fractures. What are the results? All patients achieved consolidation. The mean duration of femoral EF was 7.6 months (5–9 months). One bone loss in a distal femoral shaft treated with Sheffield EF had lengthening (5 cm) after acute short-hening. Two patients had a gradual distal femoral fracture reduction and a mechanical axis correction by TSF. Three patients with tibial bone loss had 2 trifocal bone transport (17,5 and 9 cm) and 1 bifocal bone transport 5 cm. The TSF had no additional pre-operative planning and major post-operative frame adjustments. The intra-operative devices was easier for the TSF. What are your conclusions? Circular frame osteosynthesis following initial EF, is a reliable and effective strategy for treatment in severe open femur and tibia fractures and post traumatic reconstruction.
We describe the clinical and radiological results of 38 total hip replacements (THR) using the JRI Furlong hydroxyapatite-ceramic (HAC) – coated femoral component in patients younger than 50 years. The mean age at the time of operation was 42 years and the mean length of follow-up was ten years. All patients receiving a Furlong HAC THR were entered into the study regardless of the primary pathology including patients who had undergone previous hip surgery. The mean Harris hip sc ore improved from 44 before operation to 92 at the last post-operative review. After 12 years the cumulative survival for the stem was 100%. No femoral component was revised. Our results show that the Furlong HAC implant gives excellent long-term results in young patients with high demands.
Bone Tissue Engineering Program, Institute of Health and Biomedical Innovation, Queensland University of Technology, Brisbane, QLD 4059, Australia. Osteophytes are the most remarkable and consistently distinct feature of osteoarthritis (OA). Their formation may be related to pluripotential cells in the periosteum responding to stimulus during OA. This study aimed to isolate stem cells from osteophyte tissues, and characterise their phenotype, proliferation and differentiation potential, and immuno-modulatory properties. Osteophyte derived cells were isolated from five osteophyte tissue samples collected during knee replacement surgery. These cells were characterised by the expression of cell surface antigens, differentiation potential into mesenchymal lineages, growth kinetics and modulation of allo-immune responses. Multipotential stem cells (MSCs) were identified from all osteophyte samples namely osteophyte derived MSCs (oMSCs). The surface antigen expression of oMSCs was consistent with that of mesenchymal stem cells, such as lacking the haematopoietic and common leukocyte markers (CD34, CD45) while expressing those related to adhesion (CD29, CD166, CD44) and stem cells (CD90, CD105, CD73). The longevity of oMSCs in culture was superior to that of bone marrow derived MSC (bMSCs), and they readily differentiated into tissues of the mesenchymal lineages. oMSCs also demonstrated the ability to suppress allogeneic T-cell proliferation, which was associated with the expression of tryptophan degrading enzyme indoleamine 2,3 dioxygenase (IDO). Our results showed that osteophyte derived cells had similar properties to mesenchymal stem cells in the expression of antigen phenotype, differential potential and suppression of allo-immune response. Furthermore, when compared to bMSCs, oMSCs maintained a higher proliferative capacity, which may offer an alternative source for therapeutic stem cell based tissue regeneration.
We describe the clinical and radiological results of thirty eight consecutive total hip replacements, using the JRI Furlong Hydroxyapatite ceramic coated femoral component (JRI Instrumentation Ltd, London, UK) in patients under the age of 50 at the time of surgery. The mean age at the time of operation was 42 years (range 22 to 49 years). The average length of follow up was 10 years (range 63 to 170 months). All patients receiving a Furlong HAC THR were included regardless of their primary aetiology. These included patients on whom previous hip joint surgery had taken place. The mean Harris hip score improved from 44 pre-operatively to 92 at the latest post-operative review. The mean WOMAC and Oxford scores at the latest review for this study were 29 and 16 respectively. Using the Charnley modification of the Merle d’Aubign_ and Postel hip score, at the latest follow up the mean scores were as follows: Pain 5.37, Function 5.47, and Range of Motion 5.71. The mean pain visual analogue score was 1.1 and 94% of patients returned to outdoor activities or sports. There were no reports of thigh pain at any review. There was no loss to follow-up. There were no revisions of any femoral component. Radiological review of the femoral components revealed no continuous or progressive radiolucent lines around the stem. No osteolysis was noted. Using revision or impending revision as the end point at 12 years the cumulative survival for the stem was 100% (95% CI 89 to 100). We present excellent clinical, radiological and survivrship results with the use of HAC components in young, active patients with varying primary pathology, after ten years use.
Limb lengthening by callus distraction and external fixation has a high rate of complications. We describe our experience using an intramedullary nail (Fitbone) which contains a motorised and programmable sliding mechanism for limb lengthening and bone transport. Between 2001 and 2004 we lengthened 13 femora and 11 tibiae in ten patients (seven men and three women) with a mean age of 32 years (21 to 47) using this nail. The indications for operation were short stature in six patients and developmental or acquired disorders in the rest. The mean lengthening achieved was 40 mm (27 to 60). The mean length of stay in hospital was seven days (5 to 9). The mean healing index was 35 days/cm (18.8 to 70.9). There were no cases of implant-related infection or malunion.
We describe the clinical and radiological results of 120 consecutive revision hip replacements in 107 patients, using a titanium alloy femoral component fully coated with Hydroxyapatite ceramic (HAC). The mean age at operation was 71 years (range 36 to 92). The average length of follow up was 8.0 years (range 5.0 to 12.4). All patients receiving a JRI Furlong HAC coated femoral component (JRI Instrumentation Ltd, London, UK) with a minimum follow up of 5 years were included. These included patients on whom previous revision hip joint surgery had taken place. Patients were independently reviewed and scored using the Harris Hip Score (HHS), the Charnley modification of the Merle d’Aubigne and Postel Score (MDP), and The Western Ontario and McMaster Universities Osteoarthritis index (WOMAC). Radiographs were assessed by three reviewers (blinded to clinical details) for new bone formation, osteolysis, osteointegration and radiolucent lines in each Gruen Zone. The mean Harris hip score was 85.8 (range 42 to 100) at the latest post-operative review. The mean WOMAC and MDP scores were 34.5 and 14.8 respectively. The mean pain visual analogue score (range 0 to 10) was 1.2 overall and 0.5 specifically for mid-thigh pain. There were no revisions of any femoral component for aseptic loosening. There were four stem re-revisions (3 cases of infection, 1 recurrent dislocation). Radiological review of all femoral components, including the four mentioned, revealed stable bone ingrowth with no new radiolucent lines in any zone. Using revision or impending revision for aseptic loosening as the end point, at 10 years the cumulative survival for the stem was 100% (95% CI 94 to 100). We present excellent medium to long term clinical, radiological and survivorship results with the use of a fully HAC coated titanium stem in revision hip surgery.
We describe the clinical and radiological results of 120 consecutive revision hip replacements in 107 patients, using the JRI Furlong hydroxyapatite-ceramic-coated femoral component. The mean age of the patients at operation was 71 years (36 to 92) and the mean length of follow-up 8.0 years (5.0 to 12.4). We included patients on whom previous revision hip surgery had taken place. The patients were independently reviewed and scored using the Harris hip score, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the Charnley modification of the Merle d’Aubigné and Postel score. Radiographs were assessed by three reviewers for the formation of new bone, osteolysis, osseointegration and radiolucent lines in each Gruen zone. The mean Harris hip score was 85.8 (42 to 100) at the latest post-operative review. The mean WOMAC and Merle d’Aubigné and Postel scores were 34.5 and 14.8, respectively. The mean visual analogue score for pain (possible range 0 to 10) was 1.2 overall, but 0.5 specifically for mid-thigh pain. There were no revisions of the femoral component for aseptic loosening. There were four re-revisions, three for infection and one for recurrent dislocation. Radiological review of all the femoral components, including the four re-revisions showed stable bony ingrowth and no new radiolucent lines in any zone. Using revision or impending revision for aseptic loosening as an end-point, the cumulative survival of the femoral component at ten years was 100% (95% confidence interval 94 to 100). We present excellent medium- to long-term clinical, radiological and survivorship results with the fully hydroxyapatite-ceramic-coated femoral component in revision hip surgery.
We describe the clinical and radiological results of 38 total hip replacements (THR) using the JRI Furlong hydroxyapatite-ceramic (HAC)-coated femoral component in patients younger than 50 years. The mean age at the time of operation was 42 years (22 to 49) and the mean length of follow-up was ten years (63 to 170 months). All patients receiving a Furlong HAC THR were entered into the study regardless of the primary pathology including patients who had undergone previous hip surgery. The mean Harris hip score improved from 44 before operation to 92 at the last postoperative review. After 12 years the cumulative surivival for the stem was 100% (95% confidence interval 89 to 100). No femoral component was revised. Our results show that the Furlong HAC implant gives excellent long-term results in young patients with high demands.
We reviewed 64 anterolateral decompressions performed on 63 patients with tuberculosis of the dorsal spine (D1 to L1). The mean age of the patients was 35 years (9 to 73) with no gender preponderance. All patients had severe paraplegia (two cases grade III, 61 cases grade IV). The mean number of vertebral bodies affected was 2.6; the mean pre-treatment kyphosis was 24.8° (7 to 84). An average of 2.9 ribs were removed in the course of 64 procedures. The mean time taken at surgery was 2.45 hours when two ribs were removed and 3.15 hours when three ribs were removed. Twelve patients (19%) showed signs of neurological recovery within seven days, 33 patients (52%) within one month and 12 patients (19%) after two months; but six patients (10%) showed no neurological recovery. Forty patients were followed up for more than two years. In 34 (85%) of these patients there was no significant change in the kyphotic deformity; two patients (5%) showed an increase of more than 20°.
Tibialis posterior tendon (TPT) dysfunction is a disorder of unknown aetiology. Trauma, inflammatory processes, anatomical abnormalities and iatrogenic factors have all been implicated as causative mechanisms. The condition presents with pain and swelling around the medial malleolus. The pain is characteristically worse on exercise and relieved by elevation. The disorder has been classified by Johnson and Strom (1989); stage I is characterized by pain around the medial malleolus and mild weakness of single heel raising. Without treatment the condition may progress to a fixed valgus deformity along with pes planus.
To assess the outcome of surgical decompression of stage I TPT dysfunction.
Ten cases were identified, operated on by a single surgeon over a three-year period. The patients were assessed in a dedicated clinic by administration of a questionnaire and by clinical examination.
Nine patients with an average age of 30 years (13–51) agreed to participate in the study. Six of the nine patients recalled a sporting injury to the ankle prior to onset of symptoms. Eight of these of patients underwent a course of physiotherapy prior to surgery. After decompression all patients reported reduction of pain as measured using a visual analogue scale, with five patients reporting complete resolution of pain. Patients experienced relief of pain on average four weeks (1.5–6) after surgery. All patients were able to return to work and normal leisure activities after appropriate rehabilitation.
Decompression of the tibialis posterior tendon in stage I dysfunction leads to pain relief and enables an early return to normal activities. Therefore surgical decompression of the tibialis posterior tendon may be considered in cases of stage I dysfunction which are refractory to conservative measures, particularly in young and active patients.
