Rubber gloves in orthopaedic surgery (part II): Cooke and Goodyear; Halsted and Caroline's gloves of love; from cotton to rubber after Perthes' experiments; double glove technique with Urist.

PURPOSE: This study determines the timeline for surgeons adopting rubber gloves and the double glove technique in the operating room for orthopaedic surgery. MATERIAL AND METHODS: Using the vague historical terms of discovery, acceptance, commonplace, and consistency, we analyzed the influence of the different actors in each period. RESULTS: Cotton or silk was used for early gloves; they were permeable, sometimes coated with paraffin. Uses of rubber date to the 1600 s when the Mesoamericans used rubber to make shoes. After the discovery of rubber in 1735 by the French scientist Charles de la Condamine in Peru, the rubber glove was imagined in 1834 and done for the first time by R. F. Cooke. The acceptance of rubber gloves arrived when the Goodyear-Rubber Society began to manufacture rubber gloves. Halsted, at Johns Hopkins Hospital, negotiated in 1889 with the Goodyear Rubber Company to produce thin rubber gloves to protect his nurse's hands from the dermatologic effects of the carbolic acid used to sterilize instruments. Commonplace to protect patients from bacteria of hand surgeons necessitated several decades. Dr. Joseph Bloodgood (Halsted's senior resident) remarked that gloving the surgeon with rubber gloves reduced the infection rate. Still, surgeons were reluctant to wear gloves that impaired the sense of touch. Laboratory experiments performed by G. Perthes on cotton and rubber gloves were necessary to generalize rubber gloves for practice in orthopaedic surgery. Consistency of the double-glove technique arrived during World War II when M. Urist proposed the double protection against bites from bone or bullet fragments while exploring war wounds. Only in 1965, when The Ansell Rubber Company utilized gamma irradiation as a low-cost method of sterilizing the gloves they produced, did disposable gloves become sterile. CONCLUSION: This article helps to understand the detailed discussions before surgical gloves' modern operating equipment.

A Distally Based Sartorius Muscle Flap for a Gustilo Grade-III Open Fracture of the Lateral Femoral Condyle and the Head of the Fibula with a Complex Soft-Tissue Defect: A Case Report and Review of the Literature.

CASE: We present a case of lower-limb trauma associated with an extensive soft-tissue defect around the knee joint, which led to the exposure of bone and the metalwork that was used for the management of the associated fractures. Coverage was performed with a distally based sartorius muscle flap in a single-stage procedure, allowing good recovery with a nice aesthetic and functional outcome at the 1-year follow-up. Additionally, we discuss alternative options for the coverage of severe soft-tissue defects based on the clinical context. CONCLUSION: A distally based sartorius muscle flap may be a suitable alternative for coverage of complex soft-tissue defects around the knee joint.

History of club-foot treatment; part II: tenotomy in the nineteenth century.

Clubfoot is one of the most common congenital orthopaedic anomalies and was described by Hippocrates in the year 400 BC. From manipulation in antiquity to splint and plaster in the Renaissance the treatment had improved before tenotomy. Tenotomy was tested during the 19th century and will be explained in this manuscript; the introduction of subcutaneous tenotomy of the Achilles tendon had focused the attention of surgeons on the surgical treatment of clubfeet. While this operation was very successful in the correction of equinus deformities due to poliomyelitis, cerebral palsy, and old injuries, it was not a panacea for the patient with the congenital clubfoot. To be successful, the forefoot adduction and inversion had to be corrected completely before correction of the equinus deformity could benefit the patient. For this reason operations were extended to include tenotomies of other tendons, particularly the anterior tibial tendon and incisions in the capsules of the talar joints.

Posterior Arthroscopic Tibiotalar Arthrodesis: Anatomic Feasibility Study.

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications. We mapped 22 zones of the fibular tibiotalar mortise from 10 specimens. Medial and lateral para-Achilles arthroscopic approaches were used, with a 4-mm arthroscope at 30°. For chondral resection, we used a motorized burr, curette, and osteotome. The entire plafond of the tibial mortise could be freshened in all cases, but the talar dome could be freshened in its entirety in only 20% of cases. In 80%, only the posterior two thirds could be treated, because the anterior portion descending to the neck of the talus was poorly accessible. More than 50% of the area of the malleolar grooves was freshened. One medial malleolar fracture and one posterior fibular artery lesion developed. Thus, the technique was shown to be feasible, if no frontal hindfoot deformity or tibiotalar equinus is present, which would prevent satisfactory resection of the posterior and anterior talar cartilage. The procedure allows for single-step associated subtalar fusion, requiring 2 complementary arthroscopic approaches, 1 cm distally.

Dual-mobility implants prevent hip dislocation following hip revision in obese patients.

PURPOSE: Revision total hip arthroplasty (THA) is associated with increased rates of dislocation in obese patients. It is not known whether dual-mobility implants decrease dislocation in these patients with obesity. METHODS: We retrospectively reviewed two groups of revision THAs to compare the dislocation rate between 32 obese patients (BMI >30 kg/m2) with standard cups, and 35 obese patients (BMI >30 kg/m2) with dual-mobility cups. All patients received the same implants except for diameter head (32-mm head with standard cups and 28-mm head with dual mobility) and had the same cemented stem that was not changed at revision. The patients were followed at routine intervals and were specifically queried about dislocation. The two groups were similar in terms of age, gender, causes of revision and follow-up since the primary arthroplasty. RESULTS: With standard liners, more hips in obese patients dislocated than did hips in obese patients who received dual-mobility implants. The number of dislocations in standard hips was at one year follow-up 15.6 % (5 of 32) compared with 0 % in dual-mobility hips and was at five year follow-up 21.8 % (7 of 32) compared with 2.8 % (1 of 35). After a mean follow-up of seven years no cases of loosening were found. Five patients in the obese group with a standard liner underwent re-revision surgery, the additional re-operations being necessary to treat recurrent postoperative dislocation. CONCLUSIONS: Obese patients should be counselled about the important risk of dislocation that occurs with standard liners after revision THA. Dual-mobility liners in these patients with hip revision is an efficient technique to prevent post-operative hip dislocation.

Dual-mobility arthroplasty failure: a rationale review of causes and technical considerations for revision.

PURPOSE: Dual-mobility arthroplasty is an alternative to conventional total hip arthroplasty (THA) in appropriately selected, active adults with degenerative, necrotic or post-traumatic hip disease or with revision hip arthroplasty. Numerous papers have been published with results of dual-mobility arthroplasty, but there have been no comprehensive literature reviews that summarise the most recent findings and help the orthopaedic surgeon facing different scenarios in which revision of one or both components of a dual-mobility arthroplasty is indicated. METHODS: We performed a PubMed search for papers published on dual-mobility arthroplasty that provided data on revision and add our experience in order to describe different revision scenarios. We collected data on revision for any reason, for aseptic loosening, for infection, or for dislocation. For each complication, we summarise causes and diagnosis of this complication and describe the direction of possible therapeutic options. RESULTS: The dual-mobility arthroplasty offers the benefit of increased stability without compromising clinical outcomes and implant longevity. However, as with conventional arthroplasties, complications are also reported, with the most frequent being cup loosening, dislocation, accelerated wear and infection. Dual-mobility implants also have some specific complications secondary to their specific design, with the presence of a third joint. For example, intraprosthetic dislocation due to retentive failure of the polyethylene (PE) liner on the femoral head is a complication observed exclusively with this type of implant and involves articulation failure between the femoral head and the PE liner. Mechanical conflict with the iliopsoas tendon has also been reported, probably due to femoral head size, cup design, and/or a dysplastic hip. This systematic review of the literature identified several options for treating each complication, and in particular, options regarding conserving or not of one the two articulating devices. CONCLUSIONS: These findings can inform discussions relating to risks and benefits of different therapeutic options when performing revision of a dual-mobility arthroplasty.

Outcome of knee revisions for osteoarthritis and inflammatory arthritis with postero-stabilized arthroplasties: a mean ten-year follow-up with 90 knee revisions.

PURPOSE: Patients with rheumatoid arthritis (RA) and osteoarthritis (OA) may require revision total knee replacement. Few studies have compared post-operative complications, results and risk of re-revision in RA and OA patients. MATERIAL AND METHODS: Forty-five RA patients who had undergone revision TKA from 1998 to 2010 were selected and matched with 45 OA patients who had revision during the same period. Results of the use of a revision postero-stabilized implant in osteoarthritis were compared to results of its use in inflammatory arthritis. With a mean follow-up of ten years (range, 5-17 years) we determined differences in comorbidities, risk for peri-operative adverse events, functional and radiological results, and risk of subsequent re-revision, between patients suffering from OA versus RA. RESULTS: There were higher comorbidities, post-operative (<30 days) adverse events, and mortality at average ten years FU in RA than in OA patients. The mean overall changes in function scores were greater for the RA revision group when compared with the OA revision group. Taking steroids (Cox's regression, p = 0.001), and methotrexate or TNFα blockers (Cox's regression, p = 0.02) were not significant factors for radiolucent lines in RA and for loosening. At average ten years followup, patients with RA undergoing revision TKAs were not more likely to have a re-revision (4 among 45 patients; 9 %) than patients with OA undergoing revision in our department (7 patients; 15 %). CONCLUSIONS: Similar results for the knee were observed in these two forms of arthritis in spite of the fact that the initial local joint status and general health status are worse in inflammatory rheumatoid arthritis than in "degenerative" osteoarthritis. However, complications were more frequent with RA.

Mapping the quadriceps tendon: an anatomic and morphometric study to guide tendon harvesting.

INTRODUCTION: The quadriceps tendon (QT) may be used in first-line knee ligament surgery (Anterior and Posterior Cruciate Ligaments), surgical revision and multiligament surgery. There are few published anatomic guides to QT harvesting. The present anatomic study sought to determine the ideal harvesting site and exa mined possible correlation between patellar and graft sizes. MATERIALS AND METHODS: A descriptive morphometric anatomic study was performed on 12 cadaveric knees. The reference anatomical landmark was the center of the superior edge of the patella. The QT was dissected and sliced longitudinally into five 5-mm strips. The central strip corresponded to the anatomic center of the patella. QT thickness was measured every 10 mm over a length of 100 mm. Data were analyzed on Pearson correlation test and Student, Bartlett and Fisher tests (α risk = 0.05). RESULTS: QT thickness ranged from 0.7 to 9.78 mm, for a mean 4.94 mm. Mean thickness in the lateral, central and medial strips was, respectively, 3.464, 6.040 and 3.899 mm. Central and centromedial strips were thicker than medial, centrolateral and lateral strips; central and centromedial strips were similar at, respectively, 6.040 and 6.041 mm (non-significant: p = 0.95), and significantly thicker than lateral strips. QT thickness showed significant correlation with patellar length (r = 0.75; p = 0.0048; 95% CI [+0.31; +0.93]). CONCLUSION: The present anatomical study confirmed that QT should be harvested from the central and centromedial regions. Mean thickness was 7.84 mm at the patellar insertion, 7.37 mm at 20 mm from the insertion, 6.41 at 40 mm, 5.61 at 60 mm and 4.33 at 100 mm.
