Novel Mini-Invasive Surgical Technique for Treating Fifth Metacarpal Neck Fractures: A Case Report.

BACKGROUND Fracture of the fifth metacarpal of the hand is due to trauma to the clenched fist. The non-displaced fracture can be treated by splinting and immobilization, but fracture dislocation requires individualized management to ensure the return of function. The Jahss maneuver for reduction of volar displaced metacarpal neck fractures involves flexion of the metacarpophalangeal and proximal interphalangeal joint at 90°, with the proximal phalanx used to reduce the metacarpal head. This report is of a 25-year-old male Italian pianist with a displaced fifth metacarpal neck fracture successfully treated by reduction using the Jahss maneuver and K-wire attachment of subchondral bone to the metacarpal. CASE REPORT A pianist presented with a trauma to his right hand due to punching a wall. Radiograph images demonstrated an angulated, displaced right fifth neck fracture. A specific approach was decided, considering the complexity of the musical movements and the patient's performance needs. After fracture's reduction by the Jahss maneuver, 2 retrograde cross-pinning K-wires were inserted at the subchondral bone of the metacarpal head. Healing under splinting was uneventful, and the K-wires were removed after 45 days. At 4 months after surgery, the patient had complete recovery of both range of motion and strength. CONCLUSIONS Our technique avoided piercing the metacarpophalangeal joint capsule, preventing extensor tendon damage, dislocation, instability, and pain and retraction of the extensor cuff. This novel mini-invasive technique successfully achieved early metacarpophalangeal joint motion, joint stability, and complete recovery of movements in all planes.

Volar Plate Interposition Arthroplasty of the Proximal Interphalangeal Joint: A Novel, Modified Malerich's Technique.

The choice of prosthetic or autologous reconstruction for proximal interphalangeal (PIP) joint arthroplasty in degenerative osteoarthritis represents a challenge for hand surgeons, especially in consideration of complications and patient's quality of life. We report the case of a 49-year-old woman who developed diffuse arthritis of the finger joints, especially at the PIP joint of the third right finger. Radiographs showed destruction of the PIP joint, large osteophytes, marked narrowing of joint space, severe sclerosis, and deformation of bone contour. Through a volar approach, we removed the osteophytes, reshaped the joint, and performed an arthroplasty with volar plate interposition. The patient had an improved range of motion at 3 months postoperatively. This case study gives a detailed description and discussion, together with literature revision, of volar plate interposition arthroplasty to treat PIP osteoarthritis, as an alternative to other methods.

The Use of a High-Tech Knee Pad for Reduction of the Postoperative Effusion after Total Knee Arthroplasty.

Purpose After total knee arthroplasty (TKA), pain and swelling, especially in older and less cooperative patients, can limit the retrieval of a good range of motion and muscle tone and consequently the achievement of an optimal function outcome. A high-tech knee pad made of metal fibers emitting infrared energy was used in a group of patients undergoing TKA to assess its efficacy in the postoperative period with respect to a group with a placebo. Methods Twelve patients used knee pads after surgery for 3 weeks and were evaluated using visual analog scale (VAS), Knee Society Rating Score, Cincinnati Knee Rating Score, and painkillers at specific timings. Results At 3 weeks, all scores improved in a significant manner in the treated group compared with the placebo group. At 2 months after surgery, VAS was better in the study group than the control group, whereas other parameters were similar. However, the use of rescue drugs was less in the study group than in the placebo group. Conclusion A high-tech knee pad may contribute to a faster recovery within the first week after a knee replacement, limiting the use of painkillers and allowing a quick functional recovery by the control of pain and postoperative effusion. Level of Evidence Level II, randomized prospective study with small sample size.

Acute Traumatic Swan Neck Deformity: A Case Report of the Oblique Retinacular Ligament Lesion.

Swan neck deformity (SND) can be the manifestation of an acute trauma. We present a case report of a young basketball player with an acute traumatic SND determined by the single ulnar oblique retinacular ligament rupture. The patient caught a ball directly upon the tip of his right's hand middle finger into extension. He immediately presented a SND with impossibility to actively flex the proximal interphalangeal joint (PIPJ), while preserving active flexion and extension of the distal interphalangeal joint (DIPJ). Hyperextension of PIPJ was reducible with passive mobilization, thus allowing full passive range of motion. The SND was seen to be caused by the lesion of the ulnar oblique retinacular ligament (ORL) on its distal insertion, with consequent dorsomedial migration of the ulnar lateral band. The early surgical distal reinsertion of the ORL allowed the restoration of the original kinematics of the finger flexion-extension.
