Cemented bipolar hemiarthroplasty for unstable intertrochanteric fracture in elderly patients over 70 years: Boon or bane?

INTRODUCTION: The surgical management of intertrochanter femur fracture in elderly patient is still under debate. Various implants can be utilised but prosthetic replacement is gaining popularity. This study was performed to evaluate the functional and clinical outcomes of cemented bipolar arthroplasty as a primary treatment for unstable intertrochanteric fracture in elderly patients (> 70 years). MATERIALS AND METHODS: Thirty-seven patients with unstable intertrochanteric fracture in elderly patient (> 70 years) who underwent cemented bipolar hemiarthroplasty. Intra-operative and post-operative complications were noted; functional outcomes were assessed using Harris hip score (HHS). All patients were followed up for a minimum of 12 months. RESULTS: Overall 90% of patients has some minor or major intra or post-operative complication. One year mortality rate was 16% (6/37). Cardiopulmonary events were the most common life threatening incident. Mean fall in Haemoglobin was 1.6 gm/dL. The average time for full weight bearing mobilisation with the help of walker was 2.8 ± 1.2 days (1-8 days). The average duration of surgery was 58 ± 6 min (44-96 min) with an average blood loss of 126 ± 24 mL (90-380 mL). HHS at the end of 12 months was 77. CONCLUSIONS: The use of bipolar hemiarthroplasty in senile patient with unstable hemiarthroplasty gives an advantage of early weight bearing. However, it is associated with risk of significant intra or post-operative morbidity due to intra-operative trauma, surgical time and blood loss during the surgery. Although hemiarthroplasty can be a single-time solution to the complexities of intertrochanter fracture in elderly patients but should be performed in selected patients only.

Acquired Hallux Varus Deformity Correction: Pivotless Distraction Technique.

Acquired hallux varus deformity secondary to postburn contracture is a rare condition. It causes cosmetic disfigurement, pain, and inability to wear a shoe. Soft-tissue procedures and tendon transfers have been described for correction; however, these may require multiple operations and the outcome may be poor. We report a 6-year-old neglected case of hallux varus deformity secondary to burn contracture successfully managed by contracture release with pivotless distraction technique using a biplanar distractor and skin grafting with Z-plasty in the same procedure. The deformity was corrected to a lesser extent and with good functional outcomes. The scar was excised and Z-plasty was performed. The medial joint capsule was released. We used gradual differential distraction with monitoring on sequential radiographs. Pain-free flexion of 45° and extension of 40° were achieved and the patient was able to wear shoes after 4 weeks postoperatively. Hallux varus is a multidimensional deformity. A severe and rigid deformity might not respond well to tendon transfers in a single stage. Our described technique can be used to correct rigid hallux varus deformity with preservation of joint function.

Proximal Tibiofibular Joint: A Forgotten Entity in Multi-Ligament Injuries of the Knee.

PURPOSE: The proximal tibiofibular joint (PTJF) can be injured with the structures in the lateral aspect of the knee in a multi-ligament knee injury (MLKI) patient. Such injuries are scarce but require attention in the management of the complex MLKIs. The assessment and management of such injuries are not well described in the English literature. This study describes the frequency of PTFJ injuries, clinical assessment and functional outcomes of such injuries in MLKI patients. METHODOLOGY: The data were collected retrospectively from the cohort from 2013 to 2018. The 84 MLKI were included in the study, out of which 9 patients had associated PTFJ injury. All the PTFJ injuries were operated by one single surgeon (D.S) which involves stabilization with K-wires (Kirschner wire) and fixation with 4 mm cancellous cannulated screw along with reconstruction surgery for MLKI in single stage. RESULTS: The frequency of PTFJ injury in our patient cohort is 10.71%. Three patients out of the nine patients received Larson procedure apart from the fixation of PTFJ. At a mean follow-up of 13 months, the Lysholm score was 77.4 (range: 69-86) and mean modified Cincinnati score was 62 (range: 52-72). There was grade I posterior laxity present in one patient with PCL and PLC injury, one patient with ACL, PCL and PLC injury, and one patient with ACL, PCL, MCL and PLC injury at final follow-up. Terminal flexion of 15° or more restriction was noted in six patients. All patients were satisfied with the outcome. CONCLUSION: Evaluation of PTFJ should be an integral part of preoperative as well as an intraoperative examination of MLKI patients. The fixation of this joint is of utmost importance for the reconstructive ligament procedures on the lateral aspect of the knee. The dial test used for the assessment of the integrity of PLC injury should have a prerequisite of proximal tibiofibular joint stability, otherwise, it can lead to erroneous assessment. LEVEL OF EVIDENCE: IV.

3D CT evaluation of femoral and tibial tunnels in anatomic double bundle anterior cruciate ligament reconstruction.

BACKGROUND: An anatomical double bundle ACL reconstruction replicates the anatomy of native ACL as the tunnels are made to simulate the anatomy of ACL with AM and PL bundle foot prints. The goal of anatomic ACL reconstruction is to tailor the procedure to each patient's anatomic, biomechanical and functional demands to provide the best possible outcome. The shift from single bundle to double bundle technique and also from transtibial to transportal method has been to provide near anatomic tunnel positions. PURPOSE: To determine the position of femoral and tibial tunnels prepared by double bundle ACL reconstruction using three dimensional Computed tomography. STUDY DESIGN: A prospective case series involving forty patients with ACL tear who underwent transportal double bundle ACL reconstruction. METHOD: Computed tomography scans were performed on forty knees that had undergone double bundle anterior cruciate ligament reconstruction. Three-dimensional computed tomography reconstruction models of the knee joint were prepared and aligned into an anatomical coordinate axis system for femur and tibia respectively. Tibial tunnel centres were measured in the anterior-to-posterior and medial-to-lateral directions on the top view of tibial plateau and femoral tunnel centres were measured in posterior to anterior and proximal-to-distal directions with anatomic coordinate axis method. These measurements were compared with published reference data. RESULTS: Analysing the Femoral tunnel, the mean posterior-to-anterior distances for anteromedial and posterolateral tunnel centre position were 46.8% ± 7.4% and 34.5% ± 5.0% of the posterior-to-anterior height of the medial wall and the mean proximal-to-distal distances for the anteromedial and posterolateral tunnel centre position were 24.1% ± 7.1% and 61.6% ± 4.8%. On the tibial side, the mean anterior-to-posterior distances for the anteromedial and posterolateral tunnel centre position were 28.8% ± 4.3% and 46.2% ± 3.6% of the anterior-to posterior depth of the tibia measured from the anterior border and the mean medial-to-lateral distances for the anteromedial and posterolateral tunnel centre position were 46.5% ± 2.9% and 50.6% ± 2.8% of the medial-to-lateral width of the tibia measured from the medial border. There is high Inter-observer and Intra-observer reliability (Intra-class correlation coefficient). DISCUSSION AND CONCLUSION: Femoral AM tunnel was positioned significantly anterior and nearly proximal whereas the femoral PL tunnel was positioned significantly anterior and nearly distal with respect to the anatomic site. Location of tibial AM tunnel was nearly posterior and nearly medial whereas the location of tibial PL tunnel was very similar to the anatomic site Evaluation of location of tunnels through the anatomic co-ordinate axes method on 3D CT models is a reliable and reproducible method. This method would help the surgeons to aim for anatomic placement of the tunnels. It also shows that there is scope for improvement of femoral tunnel in double bundle ACL reconstruction through transportal technique.

A Percutaneous Technique to Reposition the Cortical Button of Adjustable-Loop Devices in Anterior Cruciate Ligament Reconstruction.

Adjustable-loop devices are relatively new but quite popular and have been routinely used for around a decade in arthroscopic anterior cruciate ligament reconstruction for hamstring graft fixation on the femur. They allow surgeons to adapt to different tunnel lengths, eliminate the need for multiple loop sizes, decrease the "bungee cord effect," maximize the amount of graft within the femoral socket available for incorporation, and allow retensioning of the graft. Apart from these advantages, certain complications are associated with the use of adjustable-loop devices. When the cortical button is being pulled up through the femoral tunnel, it may be pulled up with greater force, causing it to come out of the vastus lateralis, the iliotibial band, or even the skin. When the graft is pulled back from the tibial side, the cortical button may flip in the substance of the vastus lateralis or outside the iliotibial band. This soft-tissue interposition can cause ischemic necrosis of the interposed tissue, soft-tissue irritation, migration of the cortical button, or early loosening of the graft, leading to anterior cruciate ligament reconstruction failure. We describe a percutaneous solution to this common intraoperative technical complication. The outer sheath of a 4.5-mm arthroscope, 4.5-mm acromionizer, or notchplasty burr can be safely used to put the cortical button back against the lateral cortex of the femur.

A Rare Case of Complex Carpal Injury: Divergent Trapezium-Trapezoid Fracture Dislocation.

Background Divergent trapezium-trapezoid fracture dislocation is a rare and complex injury. The authors present an unusual case of dislocation of the trapezium-trapezoid complex with scaphoid fracture. Case Description A 25-year-old man suffered a road traffic accident leading to complex carpal injury due to axial and rotation forces (steer wheel injury) on the left wrist. X-rays and computed tomographic (CT) scan were done showing trapezium-trapezoid dissociation with fracture of distal pole of scaphoid and ulna styloid. The second metacarpal base was fractured with many ligamentous injuries in the wrist. Methods Volar flexor carpi radialis (FCR) approach was used to reduce and fix scaphoid fracture with 2.7-mm cannulated screw. Dorsal approach was used to fix fracture of second metacarpal base and perform reduction in trapezium-trapezoid complex with help of 0.8-mm K-wires, and suspension wiring of first to second and second to third metacarpal was done using 1.5-mm K-wires. The transverse flexor retinaculum (TFR) in this case was avulsed. Discussion The divergent trapezium-trapezoid joint with scaphoid fracture is not described in the literature yet. The authors implicate steering wheel injury pattern for such complex carpal fracture dislocations. CT scan is imperative to diagnose and plan treatment of such fracture morphology. Early fracture reduction and stabilization of carpal dislocations are essential for proper functioning of wrist.

Bicondylar conjoint Hoffa's fracture with patella entrapped in the fracture: A rare case report.

Bicondylar Hoffa fracture involving both the femoral condyles is a rare injury. Conjoint variety with intact bone bridge between condyles in intercondylar notch area is even rare. We report a conjoint variety of bicondylar open grade III A Hoffa's fracture with patella entrapped in the fracture with quadriceps rupture in an adult which was surgically treated with initial debridement and later open reduction with fixation and quadriceps repair. The final outcome at 1 year post injury is satisfactory. To the best of our knowledge, no such case has been reported till date in English literature.

Pediatric conjoint Hoffa's fracture: An uncommon injury and review of literature.

Coronal plane fracture of femoral condyles was first elaborated by Hoffa. These are difficult articular injuries, often described in adult skeleton and very rarely in pediatric age group. Conjoint variety with intact bone bridge between condyles in intercondylar notch area is rare. We report a conjoint variety of bicondylar Hoffa's fracture in a child which was surgically treated using headless compression screws along with a brief review of literature about fracture entity and complexities associated with it.

Arthroscopic-assisted fixation of Hoffa fracture: A case report and description of technique.

Medial condyle Hoffa fractures are intra articular injuries, which require prompt anatomical reduction and internal fixation. Arthroscopy-guided fixation of these fractures has also been advocated; the advantages include avoidance of soft tissue dissection, fast recovery and mobilization. We describe a case of a 28-year-old male patient presenting with a 10-day-old medial condylar Hoffa fracture. Skin condition prevented from conventional open reduction and internal fixation; hence, taking note of the urgency of fixation of an intraarticular fracture, arthroscopic-assisted minimally invasive approach was performed with good outcome.

Displaced Posterior Cruciate Ligament Avulsion Fractures: A Retrospective Comparative Study Between Open Posterior Approach and Arthroscopic Single-Tunnel Suture Fixation.

PURPOSE: To retrospectively compare the clinical outcomes of displaced tibial-side posterior cruciate ligament (PCL) avulsion fractures treated with open reduction and screw fixation versus arthroscopic suture fixation. METHODS: From 2005 to 2013, all displaced PCL tibial-side avulsion fractures treated surgically-initially by an open posterior approach and later by arthroscopic-assisted suture fixation-were retrospectively reviewed. The cases with radiographic evidence of greater than 3 mm of displacement and/or grade II or III laxity on the posterior drawer test were included in the study group. The associated injuries were duly treated. A conservative rehabilitation protocol was followed until radiologic fracture union occurred. The patients' clinicoradiologic assessment data at 1 year of follow-up were used for comparison between the open and arthroscopic groups. RESULTS: Forty-seven patients were available with 1 year of follow-up: 27 in the open group and 20 in the arthroscopic group. More than 90% of patients in both groups rated their knee function as normal or nearly normal. At 1 year of follow-up, knee function in terms of the Lysholm score (mean of 95.3 with 95% confidence interval [CI] 92.85 to 97.75 in open group and mean of 94.8 with 95% CI 91.38 to 98.22 in arthroscopic group; P = .812), Tegner activity level (mean of 6.8 with 95% CI 6.16 to 7.44 in open group and mean of 7.0 with 95% CI 6.44 to 7.66 in arthroscopic group, P = .677), International Knee Documentation Committee evaluation, and 1-leg hop test was comparable in both groups. The postoperative arthrometric laxity measurements with a KT-2000 arthrometer (MEDmetric, San Diego, CA) were better in the arthroscopic group, with 0 to 3 mm of laxity in 85% of cases in the arthroscopic group versus 74% in the open group. Avulsed fracture fragments were usually united by 3 months after surgery. No significant complication was noted. CONCLUSIONS: Both arthroscopic and open methods of treatment for PCL tibial-side avulsion injuries resulted in comparably good clinical outcomes, radiologic healing, and stable knees at short-term follow-up. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Tuberculosis of wrist joint in an 8-year-old child presenting as hamate osteitis: A rare case report.

Tuberculosis rarely involves wrist joint and is usually diagnosed in arthritic stage. We, hereby, describe a case of TB afflicting wrist joint in a young child. To our knowledge, similar presentation has never been reported. Diagnostic dilemma became more pronounced as the radiograph presented with features of osteitis of hamate instead of a classical phemister's triad, as is usually expected.

Partial tears of anterior cruciate ligament: Results of single bundle augmentation.

BACKGROUND: Partial tears of the anterior cruciate ligament (ACL) are common and usually present with symptomatic instability. The remnant fibers are usually removed and a traditional ACL reconstruction is done. But with increased understanding of ACL double bundle anatomy, the remnant tissue preservation along with a single bundle augmentation of the torn bundle is also suggested. The purpose of this study was to evaluate the results of selective anatomic augmentation of symptomatic partial ACL tears. Our hypothesis is that this selective augmentation of partial ACL tears could restore knee stability and function. MATERIALS AND METHODS: Consecutive cases of 314 ACL reconstructions, 40 patients had intact ACL fibers in the location corresponding to the anteromedial (AM) or posterolateral (PL) bundle and were diagnosed as partial ACL tears perioperatively. All patients underwent selective augmentation of the torn bundle, while keeping the remaining fibers intact using autogenous hamstring graft. A total of 38 patients (28 males, 10 females) were available with a minimum of 3 years followup. 26 cases had AM bundle tears and 12 cases had PL bundle tears respectively. Patients were assessed with International Knee Documentation Committee (IKDC) 2000 Knee Evaluation Form, Lysholm score; instrumented knee testing was performed with the arthrometer (KT 2000). Statistical analysis was performed to compare the preoperative and postoperative objective evaluation. RESULTS: At 3 years followup, 31.6% patients were graded A, 65.8% were graded B and 2.6% was graded C at IKDC objective evaluation. Manual laxity tests, Lysholm's score, mean side to side instrumental laxity and Tegner activity score improved significantly. 76% patients returned to preinjury level of sports activity after augmentation. CONCLUSION: The results of anatomic single bundle augmentation in partial ACL tears are encouraging with excellent improvement in functional scores, side to side laxity and return to sports activity.

Late extensor pollicis longus rupture following plate fixation in Galeazzi fracture dislocation.

Late rupture of extensor pollicis longus (EPL) tendon after Galeazzi fracture dislocation fixation is an unknown entity though it is a well-established complication following distal radius fractures. We report the case of a 55-year old male who presented with late EPL tendon rupture 4 months following internal fixation of Galeazzi fracture dislocation with a Locking Compression Plate (LCP). He was managed with extensor indicis proprius (EIP) transfer to restore thumb extension. At 4 years followup, functional result of the transfer was good. We identify possible pitfalls with this particular patient and discuss how to avoid them in future.

Inadvertent advancement of guide wire across the knee caused by incarcerated bone fragment at the nail tip during femoral nailing.

Fracture of femoral shaft in adults is common and mostly managed with intramedullary interlocking nails. Complications during closed intramedullary femoral nailing are uncommon, and mostly of them are caused by technical reasons. We describe a case of closed nailing for a femoral shaft fracture in which a jammed intramedullary guide wire, due to an incarcerated bone fragment at the nail tip, was inadvertently advanced across the knee. Forceful attempt of nail insertion caused this complication, which was probably attributed to nail design.

Nerve injury during hamstring graft harvest: a prospective comparative study of three different incisions.

PURPOSE: To compare the incidence, extent of sensory loss, its clinical effect and natural course caused by three different skin incisions used for autogenous hamstring graft harvest during anterior cruciate ligament (ACL) reconstruction. METHODS: One hundred and twenty patients who underwent hamstring graft harvest during ACL reconstruction, participated in the study. All patients were randomized into 3 groups as per the 3 incisions used-vertical, transverse and oblique. The area of sensory loss was documented as per anatomical distribution of the infrapatellar branch of saphenous nerve (IPSBN) and sartorial branch of sensory nerve (SBSN) at 6 weeks, 3 months and 6 months follow-ups. The length of incision, area of sensory loss and subjective pain score (out of 10) were also noted. RESULTS: The incidence, area of hypesthesia and persistence at 6 months were significantly higher with vertical incision at all times, whereas it was the least with oblique incision. Injury to IPSBN was maximum with vertical incision (p = 0.000), and it was similar in the transverse and oblique incision groups. The SBSN injury incidence was not significantly different between the three groups (n.s.). Subjective cutaneous hypesthesia incidence was quite low in all the three groups. The oblique incision group had highest subjective satisfaction closely followed by the horizontal incision group. CONCLUSIONS: Vertical incision has highest incidence of IPBSN injury, persistent hypesthesia, largest area of sensory loss and poorest subjective outcome. Oblique and transverse incision groups had statistically comparable results, though better outcome was noted in the oblique incision group. The SBSN injury was equally common in all the three incisions used. However, the sensory loss does not impair normal daily activities in the patients. We recommend use of oblique incision for hamstring graft harvest. LEVEL OF EVIDENCE: Therapeutic randomized controlled prospective study, level I.

We need a break: Bisphosphonates.

Bone is a dynamic tissue. It remodels, thereby maintaining serum calcium, repairing micro damage and maintaining strength. A reduction in the strength of bone leads to osteoporosis that may manifest clinically as low energy vertebral and non-vertebral fractures. The bone strength, in turn, is determined by its material, structural properties and on its remodeling potential. Commonly, osteoporosis is objectively evaluated by 'T' and 'Z' scores and these are the indicators of bone density as determined by Dexa scan; these scores correlate inversely with the fracture risk. Quite often, we forget that Dexa scan results are not the only factors determining bone strength and the association between bone density and bone strength is not fixed, and is exemplified by the example of "osteopetrosis". The same issue is happening with the prolonged use of bisphosphonates (BP's).

Isolated involvement of the posterior elements in spinal tuberculosis: a review of twenty-four cases.

BACKGROUND: The literature on tuberculosis of the posterior spinal elements without involvement of the vertebral body is scarce. In this study we report our experience with twenty-four cases of neural arch tuberculosis that were treated at our center. METHODS: We performed a retrospective review of the clinical and radiographic data of twenty-four consecutive patients who had tuberculosis of the posterior spinal elements with total sparing of the vertebral bodies and intervertebral disc space. We categorized the patients into two groups on the basis of the clinical and radiographic evaluation. The patients who had rapid onset weakness of the lower limbs or pyramidal signs or who showed evidence of epidural abscess underwent emergency decompressive laminectomy (Group A). Patients who had pyomyositis of the posterior spinal muscles without any neurological deficit, pyramidal signs, or epidural abscess were managed with antitubercular therapy alone (Group B). RESULTS: The common presenting features were spastic limb weakness and back pain. The majority of the patients had involvement of the thoracic spine. Epidural abscess, erosion of lamina, and pyomyositis of posterior spinal muscles were common imaging findings. Group A consisted of nineteen patients and Group B consisted of five patients. The mean period of follow-up was 16.9 months (range, nine to sixty months). Patients in Group A had a poorer outcome than those in Group B. Thirteen of the nineteen patients in Group A improved to become independent in the activities of daily living, with complete neurological recovery in eight patients and partial recovery in five patients. Six of the nineteen patients continued to have spastic paraplegia and were wheelchair-dependent. All of the patients in Group B remained neurologically intact during the follow-up period. None of the patients had recurrence of the disease or developed anterior element involvement or kyphotic deformity during the follow-up period. CONCLUSIONS: Neural arch tuberculosis is often missed at the time of initial presentation. In association with epidural abscess, it leads to rapid neurological deterioration. This atypical picture of spinal tuberculosis showed a high rate of neurological deficit at the time of initial presentation for medical care.
