RESUMEN
BACKGROUND: This study analysed changes in gait and pedobarography and subjective and functional outcomes after isolated Chopart joint injury. METHODS: The results of 14 patients were reviewed. Kinematic 3D gait analysis, comparative bilateral electromyography (EMG) and pedobarography were performed. RESULTS: On the injured side, the 3D gait analysis showed a significantly increased internal rotation and decreased external rotation of the hip and significantly decreased adduction and decreased range of motion (ROM) for the ankle. On the healthy side, the pedobarography revealed a significantly increased mean force in the forefoot, an increased peak maximum force and an increased maximum pressure in the metatarsal. When standing, significantly more weight was placed on the healthy side. The EMG measurements showed no significant differences between the healthy and injured legs. CONCLUSIONS: After isolated Chopart injuries, significant changes in gait and pedobarography can be seen over the long term.

BACKGROUND: Fractures of the anterior process of the calcaneus are often missed, and their treatments and results receive little attention in the current literature. The aim of this study was to specify treatment algorithms through a modification of the Degan classification. METHODS: Between 2009 and 2019, patients with APC fractures were retrospectively analyzed. The Degan classification was used and modified. Type III fractures were further divided into subgroups A (not displaced) and B (displaced). The type of treatment and complications were recorded. Return to work and posttraumatic osteoarthritis were determined as primary and secondary outcome parameters, respectively. RESULTS: Forty-one patients with 43 fractures were included. Follow-up averaged 35,5 months (range 1,5-152 months). Fractures were eight type I, six type II, 15 type IIIA and 14 type IIIB. The fracture was initially recognized in 29 (70,7%) patients, and missed in 12 (29,3%) patients, respectively. Overall, the delayed diagnosed fractures had a significantly higher complication rate (p < 0,000) than the initially diagnosed fractures and received surgical treatment significantly (p < 0,009) more often. After surgical treatment of 13 type IIIB, one nonunion occurred. Six missed type IIIA fractures were treated surgically after delayed diagnosis because of persistent symptoms. Two type I fractures required arthrodesis of the Chopart joint. Four patients did not return to work during the follow-up (3 missed type IIIA fractures, 1 type II fracture). CONCLUSION: Missed APC type IIIA fractures are at risk to develop complications, which is why computed tomography diagnostics should be performed if there is any clinical suspicion.

BACKGROUND: The role of illicit drug abuse in total joint arthroplasty is largely unknown and is likely underestimated. Patients with drug addictions often suffer from septic osteoarthritis or a necrosis of the femoral head. Purpose of the study was to evaluate the operative management and clinical outcome of total hip replacement in patients with a history of intravenous drug abuse. METHODS: This retrospective study included 15 patients with a history of intravenous drug abuse who underwent total hip arthroplasty. A total of 6 females and 9 males with an average age of 34.3 years were identified. Ten patients presented an acute bacterial coxitis (Coxitis-group) and five an aseptic osteonecrosis of the femoral head (Osteonecrosis-group). RESULTS: Ten patients with a bacterial coxitis underwent a two-staged total hip arthroplasty (THA), with temporary insertion of a drug-eluting spacer. Five patients with a necrosis of the femoral head were primarily treated with THA. All patients developed multiple re-infections after insertion of a drug-eluting spacer or THA. Only two patients finally achieved a THA without infection in the period of 3.9 years follow-up. The other 13 patients underwent a Girdlestone arthroplasty (7 patients) or total joint replacement with a chronic fistula (6 patients). CONCLUSION: THA in patients with illicit drug abuse shows a low success rate. Following septic osteoarthritis or osteonecrosis in drug-addicted patients, we recommend a two-stage procedure with temporary insertion of a drug-eluting spacer. THA might follow only under strict premises.

Despite modern conservative and surgical procedures, the number of amputations of the lower limb remains at a consistently high level. With the demographic changes and the consequent prevalence of atherosclerosis and diabetes mellitus, there is a steady increase of the risk factors that can lead to an amputation. The cause, which ultimately leads to the loss of the affected limb is therefore a symptom of the underlying disease. Primarily, the purpose of any medical treatment is the prevention of any amputation. If the preservation of the limb is not achievable, the surgical procedure follows. In principle the preparation of the stump should be as peripheral as possible. The actual prosthetic fitting starts with the dimension and the impression (negative-copy) of the prosthesis a few weeks following surgery. The technical requirements of a prosthesis will depend on the degree of mobility and the medical history of the patient. Prosthetic adjustments are available for all amputation levels and activities. The essential basic modules of a modern prosthesis can be combined and exchanged freely, so as to allow a change of function, form and axis. The aim of rehabilitation is the full reintegration into daily life. Especially young patients can provide amazing professional and athletic achievements.

Azathioprine (Aza) is a widely used immunosuppressive drug in multiple sclerosis (MS) treatment. Recently, the incidence of secondary myelodysplastic syndromes (sMDS) associated with a poor prognosis was found to be elevated in patients treated with Aza for non-malign disorders. Three hundred and seventeen MS patients were retrospectively analysed and complete blood counts were examined for those exposed to Aza. We identified one case of sMDS (cumulative dose 627 g) in a young patient and two further malignancies (cumulative doses 27 g and 54 g) in the Aza group (n = 81; 3.7%). In the non-Aza (n = 236) group, five malignancies (2.1%, P = 0.419) were identified. Including our patient, four cases of sMDS after long-term Aza therapy in MS have been reported so far. Cases suggest a time- and dose-dependent risk of sMDS in long-term therapy of MS with Aza. Long-term Aza therapy needs careful monitoring.
