Clinical outcomes with the corticotomy-first technique associated with the Ilizarov method for the management of the septic long bones non-union.

PURPOSE: Corticotomy is an integral part of the Ilizarov method on management of infected nonunited fractures that are challenging orthopaedic surgeons. However, the presence of active draining sinuses may contaminate the operative field with the potential of developing corticotomy site infection. The authors present a surgical technique aiming at minimizing or avoiding the risk of surgical site infection (SSI) in the corticotomy zone. PATIENTS AND METHODS: A total of 144 cases of draining infected nonunions were treated by Ilizarov fixator using the corticotomy-first technique. The study included humeral (18 cases), femoral (52 cases), and tibial (74 cases) nonunions. The mean age was 44.48 years with 87 males and 57 females. The mean duration of nonunion was 28.69 months. After debridement, the combined shortening and nonunion gap averaged 5.98 (range 3-10) cm. Evaluation of bone and functional results was done according to Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. RESULTS: The follow-up period averaged 51.05 (range 36-72) months. None of the cases developed corticotomy site or distraction gap infection. Union was successfully achieved in 141 cases (97.92%). Nonunion persisted in three cases (2.08%) in the distal tibia. Infection was eventually controlled in 138 cases (95.83%). Bone grafting was not needed in any case. CONCLUSIONS: The Ilizarov fixator with the corticotomy-first technique was effective in the management of draining infected non-united fractures of long bones while avoiding the SSI in the corticotomy site in all cases.

High tibial osteotomy for acute correction and subsequent gradual tensioning of the posterolateral knee ligament complex in treating genu varum combined with a lateral thrust using the Ilizarov technique in adults: surgical technique and early results.

OBJECTIVE: To report the early results of using the Ilizarov technique in performing medial wedge opening high tibial osteotomy (MWOHTO) combined with gradual tensioning of the posterolateral corner in adult patients presenting with genu varum (GV) and lateral thrust. METHODS: A prospective case series study included 12 adult patients with a mean age of 25.2 ± 8.1 years who presented with GV deformity associated with lateral thrust. They were evaluated clinically using the "hospital for special surgery" (HSS) knee scoring system. Radiological evaluation was performed using long film from hip to knee to ankle (HKA) radiographs; the overall mechanical alignment was measured as the HKA angle, the upper tibial deformity was measured as the medial proximal tibial angle (MPTA), and the joint line convergence angle (JLCA) was measured. Surgical technique included using Ilizarov for MWOHTO below the level of the tibial tubercle, acute correction of the GV deformity, fibular osteotomy, and gradual distalization of the proximal fibula. RESULTS: After a mean follow-up of 26.3 ± 6.4 months, all osteotomies were united. All patients achieved fibular osteotomy site bony union except two with a fibrous union. The HSS score showed improvement from a mean preoperative score of 88.7 ± 7.6 to a postoperative 97.3 ± 3.9 (P < 0.05). The overall mechanical lower limb alignment improved significantly from a mean preoperative HKA of 164.5 ± 3.2 to a postoperative 178.9 ± 1.6 (P < 0.05). The MPTA improved significantly from 74.6 ± 4.1 to 88.9 ± 2.3, as well as the JLCA from 12.17 ± 1.9 to 2.3 ± 1.7 (P < 0.05). Grade 1 pin tract infection was developed in four patients and was treated conservatively. In two patients, mild pain over the fibular osteotomy site was relieved over time. The lateral thrust reoccurred at the last follow-up evaluation in the two poliomyelitis patients. CONCLUSION: MWOHTO, concomitant with tensioning the knee lateral soft tissue structure at the same setting through applying an Ilizarov apparatus, showed promising functional and radiological outcomes.

Lateral column lengthening (LCL) using a rectangular shape graft for managing symptomatic flexible flatfoot showed acceptable early functional and radiological outcomes.

PURPOSE: We aimed to report the results of performing lateral column lengthening (LCL) using a rectangular-shaped graft to correct the flat foot deformity. METHODS: A total of 28 feet of 19 patients (10 males, 9 females) having an average age of 10 ± 3.2 years who were unresponsive to conservative management underwent flat foot deformity correction through LCL procedure supplemented with rectangular-shaped graft harvested from the fibula. Functional assessment was performed according to the American Orthopedic Foot and Ankle Society (AOFAS) scale. The radiographic assessment consisted of four parameters, Meary's angle in both anteroposterior (AP) and lateral (Lat.) views, calcaneal inclination angle (CIA), and calcaneocuboid angle (CCA). RESULTS: After an average of 30.2 ± 8.1 months, the AOFAS improved significantly from 46.7 ± 10.2 preoperatively to 86.7 ± 9.5 at the last follow up (P < 0.05). All the osteotomies showed healing at an average of 10.3 ± 2.7 weeks. All the radiological parameters showed significant improvement at the last follow up compared to the preoperative measurements, CIA from 6.3 ± 2.8-19.3 ± 3.5, Lat. Meary's angle from 19.3 ± 4.9-5.8 ± 2.5, AP Meary's Angle from 19.3 ± 5.8-6.1 ± 3.1, and CCA from 23.9 ± 8.2-6.8 ± 4.5, (P < 0.05). No pain at the site of the fibular osteotomy was reported in any of the patients. CONCLUSION: Lateral column lengthening using a rectangular graft effectively restores bony alignment with good radiological and clinical results, high patient satisfaction, and acceptable complications.
