Mid-term follow-up results of gradual capitate lengthening for the treatment of stage IIIA Kienbock's disease.

Purpose: This study aimed to evaluate the mid-term radiological and clinical results of gradual lengthening of capitate for the treatment of stage IIIA Kienbock's disease.

Methods: We retrospectively reviewed nine patients (five females, four males) with Lichtman stage IIIA Kienbock's disease who underwent gradual capitate lengthening at our hospital. Their clinical (range of motion (ROM), grip strength, visual analogue scale (VAS) value for pain, and Mayo wrist score (MWS)) and radiological outcomes (in terms of progression of arthritis and carpal height ratio) at the last follow-up were compared to the preoperative values.

Acute correction of distal femoral deformities by retrograde femoral nail using preoperative planning.

Purpose: This study presents the technique and results of acute correction of distal femoral deformities using retrograde femoral nailing based on preoperative planning without using a fixator.

Methods: Twenty-eight patients (34 limbs: 22 left-sided, 12 right-sided, mean age = 36 years) undergoing distal femoral deformity correction with retrograde femoral nailing between 2013 and 2020 were examined retrospectively. The osteotomy line, block screw location and number were identified by detailed preoperative planning.
