Full thickness open tear of the tendoachilles - Functional outcomes following a stable,single stage repair

ObjectiveOpen injuries of the Tendoachilles present a challenge to the treating surgeon. Although, common in our setting, there is a paucity of literature regarding management of the same. The purpose of this retrospective study was to analyse the functional outcomes following debridement and primary repair of open tears of the Tendoachilles.Materials and methodsPatients with open tears of the tendoachilles, between January 2012 to January 2017. After obtaining demographic data, including mechanism of injury, all patients were managed by adequate debridement and primary repair, by Pennington’s modification of Kessler’s technique in a single sitting, paratenon closed circumferentially, plantaris reinforcement used when end to end repair couldn’t be achieved. Below knee cast for 2 months. Weight bearing started at three months. Statistical analysis using paired t-test for calf circumference, ankle range of motion comparing with uninjured limb. Functional outcome assessment by AOFAS hindfoot score and Achilles tendon rupture score.Results23 male patients, mean age 35, were analysed. Field injury was the most common mechanism, with slip in Indian lavatory pans accounting for four patients. Average time to surgery from injury was 22 hours. Plantaris reinforcement in one case. No case of wound dehiscence, scar adherence, tendon rerupture or infection. One patient had serous discharge at three weeks which settled with oral antibiotics. 21 patients performed single heel raise. There was no significant difference in calf circumference and ankle range of motion compared to uninjured limb. Mean AOFAS score was 92, mean Achilles tendon rupture score 77.ConclusionThough open injuries of the tendoachilles is fraught with complications, early debridement, adequate repair of the tendon edges with circumferential closure of the paratenon, yields adequate functional outcomes with minimal complications.     

Elbow reconstruction after excision of proximal ulna tumors: Challenges and solutions

Most malignant bone tumors are treated with surgical excision, adhering to oncologic principles, followed by reconstruction to preserve form and function whenever feasible. Primary bone tumors around the elbow are rare accounting for <1% of all skeletal tumors. They pose a reconstructive challenge, due to the complex interplay between the osseous & capsulo-ligamentous structures which is essential for elbow stability and function. Tumors affecting the proximal ulna are rare and reconstruction of the defects following these tumors is extremely challenging. Various reconstruction options like arthrodesis, autogenous bone grafts, allografts, re-implantation of sterilized tumor bone, pseudoarthrosis, and endoprosthesis have been tried with variable success. However, due to lack of standardization and the rarity of the site, surgeons are often in a dilemma to choose the correct option. This can lead to suboptimal functional outcomes and long-term failures. In this article, we reviewed the published literature on proximal ulnar tumors and noted the pros and cons of various reconstructive procedures. We have also attempted to formulate reconstruction recommendations based on the level of resection of proximal ulna.

Dual antibiotic loaded bone cement in patients at high infection risks in arthroplasty: Rationale of use for prophylaxis and scientific evidence

In view of the demographic changes and projected increase of arthroplasty procedures worldwide, the number of prosthetic joint infection cases will naturally grow. Therefore, in order to counteract this trend more rigid rules and a stricter implementation of effective preventive strategies is of highest importance. In the absence of a "miracle weapon" priorities should lie in evidence-based measures including preoperative optimization of patients at higher infection risks, the fulfilment of strict hygiene rules in the operating theatre and an effective antibiotic prophylaxis regimen. Instead of a "one size fits all" philosophy, it has been proposed to adjust the antibiotic prophylaxis protocol to major infection risks taking into account important patient-and procedure-related risk factors. A stronger focus on the local application mode via use of high dose dual antibioticloaded bone cement in such risk situations may have its advantages and is easy to apply in the theatre. The more potent antimicrobial growth inhibition in vitro and the strong reduction of the prosthetic joint infection rate in risk for infection patients with aid of dual antibiotic-loaded bone cement in clinical studies align with this hypothesis.     

Immediate rehabilitation of a rheumatoid arthritis patient with single-piece implants

Introduction and importanceThe aim of this article is to report the long-term outcome of full mouth rehabilitation with single piece, smooth surface implants following immediate loading protocol on a patient suffering with RA and severe unilateral condylar resorption.Case presentationHere, we present a challenging case of a patient suffering from Rheumatoid Arthritis who was stabilized and completed successfully with a 4 year follow-up period. Prosthetic management optimized the inter-occlusal relationship to maintain both function and esthetic integrity. Single piece implants are designed to engage and take support from the cortical bone low in metabolic activities thus promoting the force transmission through apical threads that are engaged in the cortical bone.DiscussionRheumatoid Arthritis [RA] is an auto-immune inflammatory condition in which the inflamed and hypertrophic synovial membrane grows into the articulation surfaces. The Temporomandibular Joints [TM] are frequently involved in rheumatoid arthritis. According to the literature on RA, due to frequent periodontitis, decreased salivary secretion, medication, as well as decrease in bone regenerative potential, RA is often considered as a relative contraindication in the use of implants. Atrophic jaws and cases with comorbidities like osteoporosis, diabetes, rheumatoid arthritis, periodontally infected cases are restored with high success by single piece smooth surface.ConclusionTo the best of our knowledge, this may be the first case of immediate functional loading by bi-cortical single piece implants.     

Single channel activity associated with the calcium dependent outward current inHelix pomatia

A recently improved version of the extracellular patch clamp technique (9, 13) was used to record currents from microscopic membrane areas of Helix neurons with predominant Ca²⁺ dependent outward currents. Current fluctuations in the patches consisted mainly of frequently interrupted, one-sided steps indicating discrete open-closed state changes of single channels with an ohmic conductance of approximately 19 pS. Frequency of occurrence of the elementary events compares with amplitudes of macroscopic currents during depolarizing voltage steps of varied amplitude. Average delays in appearance of the events vary in line with delayed time courses of the cell's outward current.
